Description

本発明は、送風機に接続して使用される集塵袋および集塵装置に関する。   The present invention relates to a dust collection bag and a dust collection device that are used by being connected to a blower.

一般に、建築、土木現場等の作業時に発生する粉塵、または清掃時等に舞い上がるほこりが作業場および作業者へ飛散、付着するのを防止するため、および、作業者の視界を防ぐために、以下のような対策がとられていた。例えば、中小現場においては、粉塵またはほこり(以下、塵埃と称する)対策は作業者の自己管理に任せられ、塵埃が気になる場合はホームセンターなどで購入した使い捨てマスクを着用したり、少量の塵埃であればタオルを口、鼻に巻き付けて作業を行っていた。しかしながら、塵埃対策として十分といえるものではなかった。   In general, in order to prevent dust generated during construction, civil engineering work, etc., or dust that rises during cleaning, etc. from scattering and adhering to the workplace and workers, and to prevent workers from seeing, Measures were taken. For example, at small and medium-sized sites, dust or dust (hereinafter referred to as “dust”) countermeasures are left to the operator's self-management. If dust is a concern, wear a disposable mask purchased at a home center or a small amount of dust. Then I wrapped a towel around my mouth and nose. However, it was not sufficient as a dust countermeasure.

また、大型現場では、送風機などの機械を使って塵埃を吸引して、送風機に接続されたダストホース(ジャバラホース)を使って作業現場外へ廃棄していた。しかし、その場をしのいで作業への負担を少なくしているだけにとどまるもので、塵埃対策として十分といえるものではなかった。時には、一般家庭を含む周辺に塵埃が飛散し、一般家庭等への環境影響を免れないという問題が発生していた。   At large sites, dust is sucked using a machine such as a blower and discarded outside the work site using a dust hose (bellows hose) connected to the blower. However, it was only enough to reduce the burden on the work over the spot and was not sufficient as a dust countermeasure. At times, there has been a problem that dust is scattered around surroundings including ordinary households, and the environmental impact on ordinary households cannot be avoided.

従来、非特許文献1において、送風機に簡単脱着でき、集塵作業が容易で、塵埃の破棄が一般家庭等への環境影響なしに行うことが可能な集塵袋が記載されている。この集塵袋は、10μmより小さい空中浮遊粒子または汚染物質等を効果的に捕集して、作業空間での空中浮遊粒子または汚染物質等の移動を減少させ、1立方フィートの作業空間の環境を向上させることができること記載されている。また、集塵袋の全長にわたって開口用ファスナーが設けられ、集塵袋の内部を清掃することによって、集塵袋の再使用が可能になることが記載されている。さらに、24インチ以下の送風機に簡単に装着できることが記載されている。   Conventionally, Non-Patent Document 1 describes a dust collection bag that can be easily attached to and detached from a blower, can easily collect dust, and can be disposed of without dust having an environmental impact on ordinary households. This dust bag effectively collects airborne particles or pollutants etc. smaller than 10 μm, reduces the movement of airborne particles or pollutants etc. in the work space, and the environment of 1 cubic foot work space It is described that can be improved. Further, it is described that an opening fastener is provided over the entire length of the dust bag, and the dust bag can be reused by cleaning the inside of the dust bag. Furthermore, it is described that it can be easily mounted on a blower of 24 inches or less.

そして、図4に示すように、集塵袋20は、略円筒状の本体部21からなり、その一端には、送風機27の吹出口部28と装着して、塵埃Dを含む空気を本体部21の内部に取り入れるための取入口部24を有し、他端は閉じた底部25を有する。また、本体部21は、取入口部24側に所定径を有し、塵埃Dを含む空気を本体部21の内部へ導入するための導入部22が形成され、底部25側には導入部22より外径が大きく形成され、塵埃を収納するための収納部23が形成されると共に、本体部21の長手方向に取入口部24から底部25にわたって開口用ファスナー26が設けられている。   And as shown in FIG. 4, the dust bag 20 consists of the substantially cylindrical main-body part 21, The air outlet part 28 of the air blower 27 is attached to the end, and the air containing dust D is main-body part 21 has an inlet 24 for taking in, and the other end has a closed bottom 25. The main body portion 21 has a predetermined diameter on the intake port portion 24 side, and an introduction portion 22 for introducing air containing dust D into the main body portion 21 is formed, and the introduction portion 22 is formed on the bottom portion 25 side. An outer diameter is formed larger, a storage portion 23 for storing dust is formed, and an opening fastener 26 is provided from the intake portion 24 to the bottom portion 25 in the longitudinal direction of the main body portion 21.

また、特許文献1でも、図示しないが、粉塵、落葉、木片等の吹き出し作業または吸い込み作業において、送風機の吹出口部に装着して使用される、非特許文献1と同一形態の集塵袋が記載されている。   Also, in Patent Document 1, although not shown, a dust collection bag having the same form as Non-Patent Document 1 is used by being attached to a blower outlet of a blower in a blowing operation or suction operation of dust, fallen leaves, wood pieces, or the like. Are listed.

送風機付属品(Blower Accessories)、“集塵袋(Dust Containment Bag)”、[online]、テンペストテクノロジィ(TEMPEST TECHNOLOGY)、[平成17年3月18日]、インターネット(URL:http://www.tempest-edge.com/blowers/accessories.htm)Blower Accessories, “Dust Containment Bag”, [online], TEMPEST TECHNOLOGY, [March 18, 2005], Internet (URL: http: // www. tempest-edge.com/blowers/accessories.htm) 特開2002−332995号公報(段落0030、図11)JP 2002-332995 A (paragraph 0030, FIG. 11)

しかしながら、従来の集塵袋においては、以下に示すような問題が存在した。集塵袋の本体部を構成する材料として、通気性を有するメッシュ状の布製シートを使用することが一般的であるが、この布製シートは、集塵袋の連続使用によって、メッシュの開口部が本体部の内部に収納された塵埃によって詰まる、すなわち、目詰まりが発生しやすかった。それによって、集塵袋は、集塵能力が低下し、寿命が短くなるという問題があった。   However, the conventional dust bag has the following problems. As a material constituting the main body of the dust bag, it is common to use a mesh-like cloth sheet having air permeability. However, this cloth sheet has a mesh opening due to continuous use of the dust bag. It was clogged with dust stored inside the main body, that is, clogging was likely to occur. As a result, the dust collecting bag has a problem that the dust collecting ability is lowered and the life is shortened.

また、非特許文献1に記載された集塵袋20では、本体部21の全長にわたって設けられた開口用ファスナー26を開口することによって本体部21を展開し、本体部21の内面を清掃、例えば、電気掃除機等で吸引して、本体部21の目詰まりを解消させ、集塵袋20の寿命を伸ばすことが行われていた。しかしながら、このような清掃作業は、作業場および作業者への塵埃の飛散、付着が再度発生する危険があり、また、作業者の負担を増加させると共に、清掃作業が長時間になるという問題があった。   Moreover, in the dust bag 20 described in the nonpatent literature 1, the main body part 21 is expand | deployed by opening the fastener 26 for opening provided over the full length of the main body part 21, and the inner surface of the main body part 21 is cleaned, for example, Then, suction with a vacuum cleaner or the like was used to eliminate clogging of the main body 21 and extend the life of the dust bag 20. However, such a cleaning work has a risk of dust scattering and adhering to the workplace and the worker again, increasing the burden on the worker, and lengthening the cleaning work. It was.

さらに、集塵袋20では、本体部21の内容積を大きくして、塵埃Dの分別に寄与する布製シートの表面積を増加させると共に、集塵された塵埃Dの収納空間を増加させることによって、目詰まりを防止し、寿命を延ばすことも行われていた。しかしながら、集塵袋20が大型化しコスト高になるという問題があった。   Further, in the dust bag 20, by increasing the internal volume of the main body portion 21 and increasing the surface area of the cloth sheet that contributes to the separation of the dust D, the storage space for the collected dust D is increased, It was also attempted to prevent clogging and extend the life. However, there is a problem that the dust bag 20 becomes large and expensive.

本発明は前記問題に鑑みてなされたものであり、塵埃による目詰まりが発生しても、迅速、かつ、簡単に解消できるため、集塵能力に優れ、寿命の長い、作業者への負担が少ない、かつ、集塵作業の時間短縮が図れる集塵袋および集塵装置を提供することを目的とする。   The present invention has been made in view of the above problems, and even if clogging due to dust occurs, it can be quickly and easily resolved. An object of the present invention is to provide a dust collection bag and a dust collection device that can reduce the time required for dust collection work.

前記課題を解決するために、請求項1に記載の発明は、送風機に接続され、空気中の塵埃を集塵する集塵袋において、筒状の内部空間を有する柔軟な通気性シートからなる筒状胴体の一端部に前記送風機の吹出口部に接続される取入口部を、その一端部と反対側の他端部に排出口部を有すると共に、前記筒状胴体の前記排出口部側に、前記内部空間の軸方向に直交する断面の内部空間断面積が当該排出口部に向かって減少する集塵部を有する本体部と、前記本体部の排出口部に接続される筒状の連結部と、前記連結部の前記排出口部が接続される一端部と反対側の他端部に接続され、前記本体部より小さな内容積を有すると共に、柔軟な通気性シートからなる袋状の回収部とを備える集塵袋として構成したものである。   In order to solve the above-mentioned problem, the invention according to claim 1 is a dust collection bag that is connected to a blower and collects dust in the air, and is formed of a flexible air-permeable sheet having a cylindrical inner space. An intake port connected to the blower outlet of the blower at one end of the cylindrical body, a discharge port at the other end opposite to the one end, and on the discharge port side of the cylindrical body A main body portion having a dust collecting portion in which an inner space cross-sectional area of the cross section orthogonal to the axial direction of the inner space decreases toward the discharge port portion, and a cylindrical connection connected to the discharge port portion of the main body portion And a bag-like collection made of a flexible air-permeable sheet having an inner volume smaller than that of the main body and connected to the other end opposite to the one end to which the discharge port of the connecting portion is connected. It is comprised as a dust collection bag provided with a part.

前記構成によれば、送風機の吹出口部から吹き出された塵埃を含む空気が取入口部から本体部の内部に取り入れられる。取り入れられた空気は、本体部を構成する通気性シートによって、空気と塵埃に分別され、空気は本体部外に排出され、塵埃は内部空間断面積が減少した集塵部に集塵される。そのため、本体部、特に集塵部以外の本体部の通気性シートの開口部が塵埃で詰まる、すなわち、目詰まりの発生が減少する。また、集塵された塵埃は、本体部を外部からたたく等することによって、集塵部から連結部を通って回収部に容易に排出される。そのため、本体部の内部の塵埃の量が減少し、目詰まりの発生がより一層減少する。また、目詰まりが発生しても、迅速、かつ、簡単に目詰まりが解消される。その結果、集塵能力が向上し、従来の集塵袋ように頻繁に本体部の内部を清掃する必要がなくなると共に、従来の集塵袋(本体部)より小さな内容積を持った集塵袋(本体部)で十分な集塵を行うことが可能となり、集塵袋が小型化する。さらに、回収部が簡易な構成となり、集塵袋の作製が容易で、低コストとなると共に、回収部の持ち運びと廃棄が簡単となる。   According to the said structure, the air containing the dust blown from the blower outlet part of the air blower is taken in into the inside of a main-body part from an inlet_port | entrance part. The taken-in air is separated into air and dust by a breathable sheet constituting the main body, and the air is discharged out of the main body, and the dust is collected in a dust collecting portion having a reduced internal space cross-sectional area. Therefore, the opening of the air permeable sheet of the main body portion, particularly the main body portion other than the dust collecting portion is clogged with dust, that is, the occurrence of clogging is reduced. Further, the collected dust is easily discharged from the dust collecting section through the connecting section to the collecting section by hitting the main body from the outside. Therefore, the amount of dust inside the main body is reduced, and the occurrence of clogging is further reduced. Even if clogging occurs, clogging is quickly and easily eliminated. As a result, the dust collection capacity is improved, and it is no longer necessary to clean the inside of the main unit as frequently as the conventional dust collection bag, and the dust collection bag has a smaller internal volume than the conventional dust collection bag (main unit). (Main body part) can perform sufficient dust collection, and the dust collection bag is downsized. Furthermore, the collection unit has a simple configuration, making it easy to produce a dust bag, reducing the cost, and simplifying the carrying and disposal of the collection unit.

また、請求項2に記載の発明は、送風機に接続され、空気中の塵埃を集塵する集塵装置において、筒状の内部空間を有する柔軟な通気性シートからなる筒状胴体の一端部に前記送風機の吹出口部に接続される取入口部を、その一端部と反対側の他端部に排出口部を有すると共に、前記筒状胴体の前記排出口部側に、前記内部空間の軸方向に直交する断面の内部空間断面積が当該排出口部に向かって減少する集塵部を有する本体部と、前記本体部の排出口部に接続される筒状の連結部と、前記連結部の前記排出口部が接続される一端部と反対側の他端部に接続される回収部とを備えると共に、前記回収部が、前記連結部と接続される接続管と、前記接続管と連通する回収袋および前記回収袋に隣接する吸引機を内蔵する回収部本体とを備える集塵装置として構成したものである。   According to a second aspect of the present invention, there is provided a dust collector that is connected to a blower and collects dust in the air, and is provided at one end of a cylindrical body made of a flexible air-permeable sheet having a cylindrical inner space. An intake port connected to the blower outlet of the blower has a discharge port at the other end opposite to the one end, and the shaft of the internal space on the discharge port side of the cylindrical body. A main body portion having a dust collecting portion in which an internal space cross-sectional area of a cross section perpendicular to the direction decreases toward the discharge port portion, a cylindrical connection portion connected to the discharge port portion of the main body portion, and the connection portion A recovery portion connected to the other end portion on the opposite side to the one end portion to which the discharge port portion is connected, and the recovery portion is connected to the connection portion and to the connection tube And a collection unit main body containing a suction device adjacent to the collection bag. Those configured as a device.

前記構成によれば、回収部本体の吸引機の吸引力によって、本体部の内部(集塵部)に集塵された塵埃が排出されるため、本体部の内部の塵埃の量がより一層減少し、目詰まりの発生がより一層減少する。また、目詰まりが発生しても、より一層迅速、かつ、簡単に目詰まりが解消される。   According to the above configuration, the amount of dust inside the main body is further reduced because the dust collected inside the main body (dust collecting portion) is discharged by the suction force of the suction unit of the recovery unit main body. Therefore, the occurrence of clogging is further reduced. Moreover, even if clogging occurs, clogging can be solved more quickly and easily.

本発明に係る集塵袋によれば、集塵能力に優れ、寿命の長い、作業者への負担が少ない、かつ、集塵作業の時間短縮が図れるものとなる。加えて、同じ集塵能力の従来の集塵袋と比べて、小型化することが可能となり、コストが低くなる。
また、集塵装置によれば、回収部が吸引機を内蔵する回収部本体を備えることにより、前記効果がより一層高まる。
According to the dust collection bag of the present invention, the dust collection ability is excellent, the lifetime is long, the burden on the operator is small, and the time for the dust collection work can be shortened. In addition, it is possible to reduce the size and cost as compared with a conventional dust bag having the same dust collection capability.
Moreover, according to the dust collector, the said effect is further improved by providing the collection | recovery part main body which incorporates a suction device in a collection | recovery part.

The connection member used for other connection methods is shown, (c) is a side view, (d) is XX sectional drawing of (c).

図1に示すように、本発明に係る集塵袋1は、送風機9の吹出口部10に接続して使用されるもので、本体部2と、連結部7と、回収部8とを備える。ここで、送風機9は、例えば、モータ等の駆動部と、駆動部によって回転する羽根部と、羽根部の回転によって発生する風を吹き出す吹出口部10とを備えるもので、市販されている送風機を使用する。そして、送風機9の大きさ(送風能力)は、集塵作業を必要とする作業空間の大きさに対応して、適宜選択される。以下、各構成について説明する。   As shown in FIG. 1, a dust collection bag 1 according to the present invention is used by being connected to an air outlet portion 10 of a blower 9, and includes a main body portion 2, a connecting portion 7, and a collecting portion 8. . Here, the blower 9 includes, for example, a drive unit such as a motor, a blade unit that is rotated by the drive unit, and a blowout port unit 10 that blows out wind generated by the rotation of the blade unit. Is used. And the magnitude | size (blower capability) of the air blower 9 is suitably selected according to the magnitude | size of the working space which requires dust collection work. Each configuration will be described below.

〔本体部〕
本体部2は、送風機9に接続され、空気中の塵埃Dを集塵する内部空間を有する柔軟な通気性シートからなる筒状胴体の一端部に送風機9の吹出口部10に接続される取入口部5を、その一端部と反対側の他端部に排出口部6を有するものである。
通気性シートは、例えば、布製シート、高分子樹脂製シート等であって、単層シートまたは積層シートからなる。シート厚は0.5〜1.0mmが好ましく、0.5mm未満であると本体部2の強度が不足し集塵作業の際に破損しやすくなり、1.0mmを超えると本体部2の柔軟性が低下し集塵作業の際の取り回しが困難になりやすく、持ち運びに不便である。
(Main body)
The main body 2 is connected to the blower 9 and is connected to the blowout port 10 of the blower 9 at one end of a cylindrical body made of a flexible air-permeable sheet having an internal space for collecting dust D in the air. The inlet 5 has a discharge port 6 at the other end opposite to the one end.
The breathable sheet is, for example, a cloth sheet, a polymer resin sheet, and the like, and is formed of a single layer sheet or a laminated sheet. The sheet thickness is preferably 0.5 to 1.0 mm. If the sheet thickness is less than 0.5 mm, the strength of the main body 2 is insufficient, and the dust tends to be damaged during dust collection. This makes it difficult to carry out dust collection work and is inconvenient to carry.

布製シートとしては、木綿、羊毛、絹等の天然繊維、ポリオレフィン系、ポリエステル系、ポリアミド系、ポリアクリル系、ポリウレタン系高分子樹脂等の合成繊維、ポリアセテート等の半合成繊維、レーヨン、ポリノジック、キュプラ等の再生繊維、またはこれらを組み合わせた繊維から公知の方法で製造した織布、編布、不織布が使用される。   As fabric sheets, natural fibers such as cotton, wool and silk, synthetic fibers such as polyolefins, polyesters, polyamides, polyacrylic and polyurethane polymer resins, semi-synthetic fibers such as polyacetate, rayon, polynosic, A woven fabric, a knitted fabric, or a non-woven fabric manufactured by a known method from a recycled fiber such as a cupra or a combination of these fibers is used.

高分子樹脂製シートとしては、ポリオレフィン系、ポリエステル系、ポリアミド系、ポリアクリル系、ポリウレタン系高分子樹脂等を公知の方法でシート状に成形加工したものが使用される。   As the polymer resin sheet, a sheet obtained by molding a polyolefin-based, polyester-based, polyamide-based, polyacryl-based, polyurethane-based polymer resin or the like into a sheet shape by a known method is used.

また、集塵作業は、送風機9の羽根部を回転させることにより塵埃を空気と共に吸入し、吸入された塵埃を含む空気を吹出口部10に接続される本体部2の内部に取り入れることによって行われる。本体部2の内部に集塵される塵埃には、送風機9を通過する際に摩擦により静電気が帯電することがある。そのため、本体部2を布製シートで構成した場合には、本体部2の内部の塵埃の量が多くなるにしたがって、本体部2にも静電気が帯電し、本体部2に作業者の手が触れたり接近したりすると、放電して作業者に不快感を与えることがある。そこで、前記繊維に金属化合物を化学結合させた導電性繊維、または金属繊維を、前記織布、編布、不織布に織り込む、または、縫い付けることが好ましい。   In addition, the dust collection work is performed by sucking dust together with air by rotating the blade portion of the blower 9 and taking the air containing the sucked dust into the main body portion 2 connected to the air outlet portion 10. Is called. The dust collected inside the main body 2 may be charged with static electricity due to friction when passing through the blower 9. Therefore, when the main body 2 is composed of a cloth sheet, static electricity is charged in the main body 2 as the amount of dust inside the main body 2 increases, and the operator's hand touches the main body 2. When approaching or approaching, it may discharge and cause discomfort to the operator. Therefore, it is preferable to woven or sew conductive fibers or metal fibers obtained by chemically bonding a metal compound to the fibers into the woven fabric, knitted fabric, or nonwoven fabric.

通気性シートは、通気度8〜18cc/cm2・secであることが好ましい。通気度8cc/cm2・sec未満であると通気性シートの開口部に塵埃が詰まりやすくなり、通気度18cc/cm2・secを超えると通気性シートの集塵能力が低下しやすい。また、通気性シートとして不織布を使用する場合には、不織布の目付量で通気度を制御することが好ましく、目付量70〜90g/m2が好ましい。なお、目付量が小さいと通気度が高くなり、目付量が大きいと通気度が低くなる。 The breathable sheet preferably has an air permeability of 8 to 18 cc / cm 2 · sec. When the air permeability is less than 8 cc / cm 2 · sec, dust tends to be clogged in the opening of the air permeable sheet, and when the air permeability exceeds 18 cc / cm 2 · sec, the dust collecting ability of the air permeable sheet tends to be lowered. Moreover, when using a nonwoven fabric as a breathable sheet, it is preferable to control an air permeability with the fabric weight of a nonwoven fabric, and the fabric weight of 70-90 g / m < 2 > is preferable. When the basis weight is small, the air permeability increases. When the basis weight is large, the air permeability decreases.

本体部2は、筒状の内部空間を有し、その軸方向に直交する断面は円形状が好ましいが、円形状に限定されず、図示しない角型形状、または、円形状と角型形状の組み合わせ(例えば、図1において同径部3が角型形状、集塵部(縮径部)4が円形状)であってもよい。また、本体部2は、本体部2の軸方向(以下、軸線方向と称す)に直交する断面の内部空間断面積が後記する排出口部6に向かって減少する集塵部4を有する。集塵部4以外の取入口部5側の本体部2は、本体部2の軸方向に沿って、内部空間断面積を変化させない(図1の同径部3参照)ことが好ましいが、図示しない取入口部5に向かって内部空間断面積を縮小または拡大する形状であってもよい。   The main body 2 has a cylindrical inner space, and the cross section orthogonal to the axial direction is preferably circular, but is not limited to a circular shape, and is not shown in the figure, or a circular shape and a rectangular shape. A combination (for example, in FIG. 1, the same-diameter portion 3 has a square shape and the dust collection portion (reduced diameter portion) 4 has a circular shape) may be used. Further, the main body 2 has a dust collection part 4 in which the internal space cross-sectional area of the cross section perpendicular to the axial direction (hereinafter referred to as the axial direction) of the main body 2 decreases toward the discharge port 6 described later. The main body 2 on the intake port 5 side other than the dust collection unit 4 preferably does not change the internal space cross-sectional area along the axial direction of the main body 2 (see the same-diameter portion 3 in FIG. 1). The inner space cross-sectional area may be reduced or enlarged toward the intake portion 5 that is not.

集塵部4は、内部空間断面積の減少率が90〜98%であることが好ましい。ここで、減少率は、本体部2の内部空間断面積の最大断面積に対する、集塵部4の内部空間断面積の最小断面積の比率をいう。具体的には、図1においては、最大断面積は内径d1を有する同径部3の内部空間断面積であって、最小断面積は内径d2を有する排出口部6側の集塵部(縮径部)4の内部空間断面積である。減少率90%未満であると、後記する連結部7の内径が小さくなり、塵埃を排出しにくくなり、回収部8に回収される塵埃の量が少なくなる。その結果、本体部2(通気性シート)に目詰まりが発生しやすくなる。減少率98%を超えると、集塵部4に塵埃が集塵しにくくなり、本体部2(通気性シート)に目詰まりが発生しやすくなる。   The dust collection part 4 preferably has a reduction rate of the internal space sectional area of 90 to 98%. Here, the reduction rate refers to the ratio of the minimum cross-sectional area of the internal space cross-sectional area of the dust collector 4 to the maximum cross-sectional area of the internal space cross-sectional area of the main body 2. Specifically, in FIG. 1, the maximum cross-sectional area is the internal space cross-sectional area of the same-diameter portion 3 having the inner diameter d1, and the minimum cross-sectional area is the dust collecting portion (reduced size) on the discharge port portion 6 side having the inner diameter d2. (Diameter portion) 4 is an internal space cross-sectional area. When the reduction rate is less than 90%, the inner diameter of the connecting portion 7 to be described later becomes small, it becomes difficult to discharge dust, and the amount of dust collected in the collecting portion 8 is reduced. As a result, the main body 2 (breathable sheet) is likely to be clogged. When the reduction rate exceeds 98%, it becomes difficult for dust to be collected in the dust collection portion 4 and the main body portion 2 (breathable sheet) is likely to be clogged.

集塵部4は、排出口部6側から所定長さLに形成されている。そして、本体部2の全長に対する所定長さLの割合は20〜40%が好ましい。割合が20%未満であると、塵埃の集塵スペース(集塵部4)が狭くなり、集塵される塵埃量が低下し、集塵されない塵埃Dが本体部2の内部空間に舞い上がり、本体部2(通気性シート)の目詰まり発生の原因となりやすい。割合が40%を超えると、本体部2(通気性シート)の内表面積が減少し、集塵能力が低下しやすい。また、風速が低下し、塵埃Dが回収部8に移動し難くなる。   The dust collection part 4 is formed in the predetermined length L from the discharge port part 6 side. And the ratio of the predetermined length L with respect to the full length of the main-body part 2 has preferable 20 to 40%. If the ratio is less than 20%, the dust collection space (dust collection unit 4) becomes narrow, the amount of dust collected decreases, and the dust D that is not collected rises to the internal space of the main unit 2 and the main unit. This is likely to cause clogging of the portion 2 (breathable sheet). When the ratio exceeds 40%, the inner surface area of the main body 2 (breathable sheet) is reduced, and the dust collection ability tends to be lowered. Further, the wind speed is reduced, and the dust D is difficult to move to the collection unit 8.

(取入口部)
取入口部5は、本体部2の送風機9側の一端部に形成され、送風機9の吹出口部10に接続され、吹出口部10から吹き出される塵埃Dを含む空気を本体部2の内部に取り入れる流路を形成するものである。また、軸線方向に直交する断面において、取入口部5の流路断面積は送風機9(吹出口部10)の大きさで決定され、吹出口部10の断面積と同等、または、それより大きいことが好ましい。取出口部5の流路断面積が吹出口部10の断面積より小さいと、取入口部5での空気の圧力損失が大きくなり、本体部2(同径部3)の内部への空気の取入を阻害しやすい。また、取入口部5の流路断面形状は、吹出口部10の断面形状と同一形状とすることが好ましい。
(Intake section)
The intake 5 is formed at one end of the main body 2 on the side of the blower 9, is connected to the blower outlet 10 of the blower 9, and air containing dust D blown out from the blower 10 is inside the main body 2. The flow path to be taken in is formed. Moreover, in the cross section orthogonal to the axial direction, the flow path cross-sectional area of the intake port portion 5 is determined by the size of the blower 9 (blow-out port portion 10), and is equal to or larger than the cross-sectional area of the blow-out port portion 10. It is preferable. If the cross-sectional area of the outlet portion 5 is smaller than the cross-sectional area of the outlet portion 10, the pressure loss of air at the inlet portion 5 increases, and the air into the main body portion 2 (same diameter portion 3) is increased. It tends to hinder uptake. Moreover, it is preferable that the flow path cross-sectional shape of the intake port 5 be the same as the cross-sectional shape of the air outlet 10.

取入口部5の吹出口部10への接続方法は、図1に示すように、吹出口部10の外周面に取入口部5の内周面を接続し、取入口部5の外周面をヒモ、マジックテープ(登録商標)等の結束手段17で結束することによって行われる。しかしながら、接着方法は前記方法に限定されず、例えば、吹出口部10の内周面に取入口部5の外周面を接続してもよい。また、図3(a)〜(d)に示すように、取入口部5の内周面に接続部材15を取り付けて吹出口部10aと接続する方法でもよい。具体的には、吹出口部10aの外周面にL字型の溝(軸線方向溝13、周方向溝14)を形成すると共に、接続部材15の内周面には前記溝に対応する突起16を形成する。そして、突起16を軸線方向から溝に挿入し、周方向に回転することによって、吹出口部10a(送風機9)に取入口部5(本体部2)が接続される。   As shown in FIG. 1, the connection method of the intake port portion 5 to the air outlet portion 10 is that the inner peripheral surface of the intake port portion 5 is connected to the outer peripheral surface of the air outlet portion 10, and the outer peripheral surface of the intake port portion 5 is connected. This is performed by bundling with a bundling means 17 such as a strap or a magic tape (registered trademark). However, the bonding method is not limited to the above method, and for example, the outer peripheral surface of the intake port portion 5 may be connected to the inner peripheral surface of the air outlet portion 10. Moreover, as shown to Fig.3 (a)-(d), the method of attaching the connection member 15 to the internal peripheral surface of the inlet part 5, and connecting with the blower outlet part 10a may be sufficient. Specifically, L-shaped grooves (axial grooves 13 and circumferential grooves 14) are formed on the outer peripheral surface of the outlet 10 a, and the protrusions 16 corresponding to the grooves are formed on the inner peripheral surface of the connecting member 15. Form. Then, by inserting the protrusion 16 into the groove from the axial direction and rotating in the circumferential direction, the intake portion 5 (main body portion 2) is connected to the outlet portion 10a (blower 9).

(排出口部)
排出口部6は、本体部2の取入口部5と反対側の他端部に形成され、後記する連結部7に接続して、集塵部4に集塵された塵埃を連結部7に排出する流路を形成するものである。また、排出口部6の軸線方向に直交する流路断面積は、前記集塵部4の減少率で決定される。また、排出口部6の断面形状は、本体部2(集塵部4)と同一形状とすることが好ましい。さらに、排出口部6の連結部7への接続は、図1に示すように、前記取入口部5の吹出口部10への接続と同様に、ヒモ、マジックテープ(登録商標)等の結束手段17で結束、または、図示しないが接続部材15を使用して、溝と突起による嵌合によって行われる。
(Discharge port)
The discharge port portion 6 is formed at the other end portion of the main body portion 2 on the opposite side to the intake port portion 5 and is connected to a connecting portion 7 which will be described later. The dust collected in the dust collecting portion 4 is connected to the connecting portion 7. A flow path for discharging is formed. Further, the flow path cross-sectional area perpendicular to the axial direction of the discharge port portion 6 is determined by the reduction rate of the dust collection portion 4. Moreover, it is preferable to make the cross-sectional shape of the discharge port part 6 the same shape as the main-body part 2 (dust collecting part 4). Further, as shown in FIG. 1, the connection of the discharge port 6 to the connecting portion 7 is a binding of string, magic tape (registered trademark), etc., similarly to the connection of the intake port 5 to the air outlet 10. Bundling is performed by the means 17, or the connection member 15 (not shown) is used to fit the groove and the projection.

〔連結部〕
連結部7は、排出口部6に接続される筒状体で、集塵部4に集塵された塵埃Dを後記する回収部8に排出させる流路を形成するものである。そして、連結部7は、柔軟性と強度を考慮して、高分子樹脂等で構成されることが好ましい。また、連結部7の軸線方向に直交する流路断面積は、塵埃の排出性を考慮して、排出口部6の流路断面積と同一とすることが好ましい。さらに、連結部7の断面形状は、排出口部6および回収部8との接続性を考慮して、排出口部6と同一形状とすることが好ましい。なお、連結部7の流路内に、流路の開閉を制御するバルブ等を設けてもよい。そして、集塵作業の際には流路を閉じて、集塵部4から回収部8に空気(集塵)が排出されないようにする。これにより、集塵能力が向上する。
(Connecting part)
The connection part 7 is a cylindrical body connected to the discharge port part 6 and forms a flow path for discharging the dust D collected in the dust collection part 4 to the collection part 8 to be described later. And it is preferable that the connection part 7 is comprised with a polymer resin etc. in consideration of a softness | flexibility and intensity | strength. Moreover, it is preferable that the flow path cross-sectional area perpendicular to the axial direction of the connecting portion 7 is the same as the flow path cross-sectional area of the discharge port 6 in consideration of dust discharge. Further, the cross-sectional shape of the connecting portion 7 is preferably the same shape as the discharge port portion 6 in consideration of the connectivity with the discharge port portion 6 and the recovery portion 8. A valve or the like for controlling the opening / closing of the flow path may be provided in the flow path of the connecting portion 7. In the dust collection operation, the flow path is closed so that air (dust collection) is not discharged from the dust collection unit 4 to the collection unit 8. Thereby, dust collection capability improves.

〔回収部〕
回収部8は、連結部7の排出口部6が接続される一端部と反対側の他端部に接続され、本体部2より小さな内容積を有すると共に、柔軟な通気性シートからなる袋状のものである。また、回収部8は、集塵部4(本体部2)から連結部7を通して排出される塵埃Dを回収するものである。このような構成により、回収部8は、持ち運びと、廃棄が簡単なものとなる。具体的には、図1に示すように、袋状容器である。

回収部8の内容量は、本体部2の内容量の1/4〜1/3であることが好ましい。回収部8の内容量が1/4未満であると、回収部8に回収される塵埃量が少なく、本体部2の内部に塵埃が残留し、本体部2の目詰まり発生につながり、集塵能力が低下しやすい。また、交換用の回収部8を準備して、複数の回収部8で回収作業を行うこともできるが、交換作業の手間が増える分、作業効率が低下、作業者の負担が増加することとなる。内容量が1/3を超えると、回収される塵埃の回収率は所定値以上に向上しないため、内容量の増加分だけ回収部8の製造コストが高くなりやすく、また、廃棄し難くなる。   The internal volume of the collection unit 8 is preferably 1/4 to 1/3 of the internal volume of the main body unit 2. If the internal volume of the collection unit 8 is less than ¼, the amount of dust collected in the collection unit 8 is small, dust remains inside the main unit 2, leading to clogging of the main unit 2, and collecting dust Capability is likely to decline. In addition, the recovery unit 8 for replacement can be prepared and the recovery operation can be performed by the plurality of recovery units 8, but the work efficiency is reduced and the burden on the operator is increased because the labor of the replacement operation is increased. Become. When the internal capacity exceeds 1/3, the recovery rate of the collected dust does not improve to a predetermined value or more, and therefore the manufacturing cost of the recovery unit 8 is likely to increase by the increase of the internal capacity, and is difficult to dispose.

回収部8を構成する柔軟な通気性シートは、集塵袋1の作製の容易さから、本体部2と同様に、布製シート、高分子樹脂製シート等で作製することが好ましい。また、回収部8の形状は、図1に示すような略円筒形状が好ましいが、塵埃Dを回収可能であれば、特に限定されず、例えば、角型形状であってもよい。   The flexible breathable sheet constituting the collection unit 8 is preferably made of a cloth sheet, a polymer resin sheet, or the like in the same manner as the main body unit 2 because of the ease of producing the dust bag 1. Moreover, the shape of the collection | recovery part 8 is preferable substantially cylindrical shape as shown in FIG. 1, However, if dust D is collectable, it will not specifically limit, For example, square shape may be sufficient.

回収部8の連結部7への接続は、図1に示すように、取入口部5および排出口部6と同様に、ヒモ、マジックテープ(登録商標)等の結束手段17で結束、または、図示しないが接続部材15(図3(c)、(d)参照)を使用して、溝と突起による嵌合によって行われる。   As shown in FIG. 1, the collection unit 8 is connected to the connection unit 7 by bundling with a bundling means 17 such as a strap, a magic tape (registered trademark), or the like, similarly to the intake port 5 and the discharge port 6.
