Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Below in conjunction with concrete accompanying drawing, realization of the present invention is described in detail.
Specific embodiments of the invention 1 as shown in figures 1-4, the non-woven former of a kind of energy-saving wind nido hot blast, comprise and organize heat exchange unit more, often organize heat exchange unit and comprise the thermal current circulation canal 3 being positioned at outside blower fan 1, heater 2 and being positioned at inside, described thermal current circulation canal 3 comprises malleation runner and negative pressure runner; Malleation runner and the negative pressure runner of often organizing heat exchange unit are arranged for paired up and down and be mutually mirror to structure, two runners comprise runner housing 31, the nest alveolus 32 set gradually from inside to outside in runner housing 31 and commutating zone 33 respectively, and runner housing 31 is for wrapping up runner.Be provided with the adjustable clearance passed through for fiber web between the commutating zone 33 of two runners, this gap is as product heat exchange zone.The hole pattern curtain supporting fiber web and move ahead is provided with in the middle of gap.
In the present embodiment, the power set maintaining air current flow are blower fan 1, are the electric heater be connected in the circulatory system for adding the device of hot-air.Equipment is made up of the blower fan 1 of 4 groups of frequency conversion drive, heater 2 and corresponding pipeline.Malleation runner is connected with the circulating line outside machine with negative pressure runner.Each nest alveolus 32 is respectively equipped with and is criss-cross arranged by 1 ~ 5 layer of nest chamber transverse slat and multiple nest chambeies riser and is arranged superimposed little airflow passage in order, and namely nest alveolus 32 is the wind nido structure be made up of radial guiding runner, horizontal runner.The nest chamber riser in nest alveolus 32 is with 20 ~ 400 millimeters spaced apart and be covered with runner.
Commutating zone 33 is positioned at the outside in nest alveolus 32, and commutating zone 33 is provided with 1 ~ 3 layer of horizontally disposed mesh plate.Runner housing 31 inwall being positioned at commutating zone 33 is provided with slot, and mesh plate activity is plugged in runner housing 31.Slot plays the effect of support and slideway, is convenient to mesh plate and extracts out and push.In Fig. 4, in figure, illustrate only the local mesh effect on mesh plate.
In the present embodiment, commutating zone 33 is provided with three-layer network orifice plate altogether, and three-layer network orifice plate interval is arranged, ecto-entad is respectively as heat exchanger plate 33a, homogenizing plate 33b and choke plate 33c.Heat exchanger plate 33a, homogenizing plate 33b and choke plate 33c are respectively equipped with the hole that diameter is 1 millimeter ~ 40 millimeters, the layout of this hole size is increased to the order of choke plate 33c successively by heat exchanger plate 33a, homogenizing plate 33b.
In the present embodiment, runner housing 31 is by housing shrouding 31a, heat-insulation layer 31b, and housing inner bag 31c forms.The cooling device of equipment adopts bleeder air-cooled structure, concrete employing cooling blower 4.
Specific works principle of the present invention is as follows:
Outside windmill transports the thermal current of coming, when nest alveolus 32, thermal current separate by single little airflow passage, thus the phenomenon of the turbulence that thermal current is produced when flowing through existing regular channels, sinuous flow reduces and even disappears.Nest chamber transverse slat and nest chamber riser play the effect of shunting and guiding, thus reduce in heat exchange zone thermal current physical quantity inequality transversely.
In region, commutating zone 33, because the air-flow flowing through little airflow passage transfers vertical motion to by transverse movement, now there is the flow perturbation that little, choke plate 33c near the outlet in nest alveolus 32 and also institute's perforate footpath larger, total air-flow is less than the area of nest chamber outlet by area, and thermal current is accelerated a little, and then is full of in the space that is made up of homogenizing plate 33b and choke plate 33c, the thermal current in this space trends towards blast unanimously on the whole, and flow velocity is consistent.This air-flow enters the space be made up of heat exchanger plate 33a and homogenizing plate 33b through homogenizing plate 33b is excessive again, in this space, although the aperture of heat exchanger plate is less, but pitch-row is also nearer, total percent opening is comparatively large on the contrary, and such thermal current also becomes large by the total area of heat exchanger plate 33a, and now flow velocity reduces, blast reduces, and therefore just forms one to flow through temperature on direction, flow velocity, blast variable gradient with thermal current.
Be be that mirror image combines and configures with malleation runner due to negative pressure runner, therefore, the variable gradient of the temperature about thermal current produced in negative pressure runner, flow velocity, blast is also mirror with the variable gradient of malleation.And when entering the negative pressure runner of combinations of pairs with it after penetrating fiber web under swabbing action at circulating fan of the thermal current of malleation runner, the thermal current that integral planar is evenly distributed also can enter negative pressure runner uniformly.Flow through the space that thermal current that heat exchanger plate 33a enters negative pressure runner will be full of between the heat exchanger plate 33a of negative pressure runner and homogenizing plate 33b again, under the swabbing action of circulating fan, homogenizing plate 33b and the choke plate 33c of negative pressure runner is flowed through by the thermal current that product takes away partial heat, enter the commutating zone of negative pressure runner, in this district, the flow velocity of thermal current increases, and the overall circulation system unit interval exchange efficiency of heat increases.
Therefore, in the heat exchange zone on the whole between positive and negative runner, the thermal current being full of space is more homogeneous in the horizontal further, thus temperature, flow, flow velocity, blast reach horizontal homogeneity and uniformity.Thus improve the quality of existing Through-Air Thermal Bonded Nonwovens production, add pliability and the comfort of product.Due to the uniformity of each manufacturing parameter, and then speed of production can be improved.
In the above embodiments, according to the feel of institute's converted products or performance requirement, the installation quantity of mesh plate can be determined.Heat exchanger plate 33a, homogenizing plate 33b and choke plate 33c not necessarily have simultaneously, can select wherein 1 ~ 3 in practical application.Such as, commutating zone 33 can only be provided with one deck mesh plate, and this mesh plate is as heat exchanger plate 33a.Commutating zone 33 is also provided with two layers of mesh orifice plate, and two layers of mesh orifice plate interval is arranged, the mesh plate being positioned at outside, as heat exchanger plate 33a, is positioned at the mesh plate of inner side as homogenizing plate 33b or choke plate 33c.Specific works principle is with reference to above-described embodiment.
The above embodiments are only the preferred embodiments of the present invention, interest field of the present invention can not be limited with this, and can be extended to other be similar to situation of the present invention, such as increase or reduce the number of wind nest body, increase or reduce the mesh plate quantity etc. of commutating zone 33, as long as ensure rational in infrastructure, and energy resource consumption can be reduced, physical quantity such as temperature, flow, flow velocity, blast that the thermal current of heat exchange zone is relevant are transversely evenly distributed, and can be used.Therefore, the equivalent variations done according to the present patent application the scope of the claims, still belongs to the scope that the present invention is contained.
