Abstract
The invention relates to a filtering device, discloses a filtering device with a venturi tube fixing structure, and aims to solve the problems of bolt breakage and toppling of the whole venturi tubes due to shear force on connecting bolts at the bottoms of the venturi tubes caused by excessively high back flushing pressure of a back flushing device of the conventional filtering device. The filtering device comprises venturi tube fixing components, a filtering element and a filter barrel, wherein the filtering element comprises venturi tubes and a filter element; the venturi tube fixing components are mounted on the venturi tubes, are connected with the venturi tubes, and are also connected with the filter barrel. According to the filtering device, the problems of bolt breakage and toppling of the whole venturi tubes caused by the shear force on the connecting bolts at the bottoms of the venturi tubes due to impact of high-speed gas generated during back flushing on the venturi tubes are effectively solved.
Description
Technical field
The present invention relates to defecator, more particularly to a kind of defecator with Wen's pipe fixation structure.
Background technology
At present pneumatic filter be widely used in metallurgy, chemical industry, oil, papermaking, medicine, food, mining, electric power, city to
Water field.The used rigid filter element of high temperature and high pressure gas filter, high temperature and high pressure gas filter can be retained when filtering
Lower dust impurities, dust impurities are piled up, are attached on filter element, can reduce the filter efficacy of filter, so general filter is all
Can be just like the aid system of back-blowing device, to remove the dust impurities on filter element, because being rigid filter element, what is used is anti-
The blowback pressure of blowing apparatus can be higher.When high temperature and high pressure gas filter carries out blowback, purge gas is blown from above filter
Enter, purge gas removes the dust deposited on filter element after accelerating through Venturi tube, and reach carries out the effect of deashing to filter
Really, without interrelated but between adjacent Venturi tube, the high-speed gas produced during blowback are impacted to Venturi tube, cause Wen
The connecting bolt of bottom of the tube is subject to shearing force, causes bolt fracture, and the problem that Venturi tube is integrally toppled over occurs.
The content of the invention
For the defect that above-mentioned prior art is present, it is an object of the invention to provide a kind of mistake with Wen's pipe fixation structure
Filter device.
In order to solve the above problems, the present invention provide solution technical scheme be, a kind of mistake with Wen's pipe fixation structure
Filter device, including Venturi tube fixation kit, filter element and filter cylinder, filter element include Venturi tube and filter element, Wen
Venturi tube fixation kit is installed on pipe, the fixation kit is connected with each Venturi tube, and is connected with filter cylinder.
By fixation kit, Venturi tube is firmly fixed, keeps in situ, such network structure is connected with filter cylinder
Connect, it is ensured that its stability, make network structure solid and reliable.
It is further that described Venturi tube fixation kit includes retainer ring, fix bar, suit fixation on the outside of Venturi tube
Ring, retainer ring surrounding are connected bar.
The netted fixed ring structure that described Venturi tube fixation kit is constituted is split type, is easily installed and dismounting, side
Just use and maintenance.
Further that retainer ring surrounding connects three fix bars, two by union joint respectively with installed in adjacent text
Retainer ring on family name's pipe is connected, and one is connected with filter cylinder by union joint in addition.
Each Venturi tube retainer ring and surrounding three-point mount, stressed effect are good, can be with effectively solving Venturi tube high pressure blowback
The problem that appearance is toppled over.
It is further that described fix bar is Collapsible structure.
The fix bar of Venturi tube retainer ring is designed as Collapsible structure, Wen's pipe fixation structure can be greatly increased not
Adaptability under same scene, environment.
It is further, installation locking mechanism in described fix bar.
The installation locking mechanism in fix bar, prevent fix bar because itself Telescopic and internal slide.
It is further that the retaining mechanism is threaded fastener.
Using screw threads for fastening, bolt is conventional reliable, convenient to keep in repair, and replaces.
It is further to install in described retainer ring and hold out against part.
Part is held out against to fixed Venturi tube and the relative position and adjusting elasticity degree of retainer ring.
Particularly, the described part that holds out against is puller bolt.
It is further that the described part that holds out against installs anti-release member.
Particularly, described anti-release member is spring washer.
Spring washer is with low cost, easy for installation, it is adaptable to assemble and disassemble frequently position.
The beneficial effect that the present invention brings is：
Using netted fixed ring structure, it is installed in the middle part of Venturi tube, is prevented using the relation of the mutual restriction between Venturi tube
Only single Venturi tube is subject to impact to topple over.
The network structure is connected with cleaner unit cylinder inboard wall, it is ensured that stability.
The netted fixed ring structure is split type, is easily installed dismounting.
Effectively solve the high-speed gas produced during blowback to impact Venturi tube, cause the connection of Wen's bottom of the tube
Bolt is subject to shearing force, causes bolt fracture, and the problem that Venturi tube is integrally toppled over occurs.

Specific embodiment
Accompanying drawing will be combined to illustrate the present invention.The retaining mechanism that the present embodiment is used is threaded fastener, locking
Part is spring washer, holds out against part for puller bolt.
As seen in figures 3-6：Venturi tube fixation kit 1 is set with Venturi tube, including retainer ring 101 and fix bar 104.It is logical
Fixation kit 1 is crossed, Venturi tube 3 is firmly fixed, keep in situ, such network structure is connected with 2 inwall of filter cylinder,
Guarantee its stability, make network structure solid and reliable.
1st, circular retainer ring 101 is installed in outside in the middle part of every Venturi tube 3.101 surrounding of circular retainer ring connects three
Fix bar 104, wherein two are connected with the retainer ring 101 on adjacent Venturi tube 3 respectively by union joint 106, in addition
One is connected with 2 inwall of filter cylinder by union joint 106.Venturi tube fixation kit constitute the netted fixed ring structure because
For split type, so be easily installed and dismounting, convenient use and maintenance.
Circular retainer ring 101 and the surrounding three-point mount of each Venturi tube, stressed effect are good, can be with effectively solving Venturi tube
The problem toppled over that high pressure blowback occurs.
2nd, fix bar 104 is designed as the mechanism of 101 spacing of telescopically adjustable retainer ring, after relative position determines passes through spiral shell
Stricture of vagina securing member 105 is fastened.The fix bar 104 of Venturi tube retainer ring 101 is designed as the mechanism of telescopically adjustable fixed ring spacing,
To can greatly increase adaptability of Wen's pipe fixation structure under different scenes, environment.Using screw threads for fastening, bolt routinely may be used
Lean on, it is convenient to keep in repair, replace.
3rd, held out against using multiple puller bolts 102 between retainer ring 101 and Venturi tube 3, and spring washer 103 is installed.Top
Tight bolt 102 is to fixed Venturi tube 3 and the relative position and adjusting elasticity degree of retainer ring 101.103 low cost of spring washer
It is honest and clean, easy for installation, it is adaptable to assemble and disassemble frequently position.
By installing the Venturi tube fixation kit described in the present embodiment, the high-speed gas produced during blowback are effectively solved
Venturi tube is impacted, is caused the connecting bolt of Wen's bottom of the tube to be subject to shearing force, is caused bolt fracture, Venturi tube occurs whole
The problem that body is toppled over.
