Description
TECHNICAL FIELD
[0001] The utility model relates to a dust collector. BACKGROUND
[0002] Generally, in a wood factory or other working place, due to sawing, grinding and other operations, the workshop is full of dust. The dust not only affects the health of workers, but also may cause dust explosion, fire and other industrial disasters. Therefore, a large industrial dust collector must be installed in the workshop to continuously filter and remove the air in the workshop.
[0003] The existing industrial dust collector, as described in Taiwan Patent No. 424564, mainly comprises a suction pump, one end of which is connected to a wind guide pipe. A ring body is provided at the outlet end of the wind guide pipe. A gas permeable bag is fitted on the upper edge of the ring body, and a dust collection bag is fitted on the lower edge of the ring body. When the suction pump is running, the dust-containing air in the workshop is sucked into the wind inlet of the wind guide pipe and guided to the ring body. The air is then backflowed in the space formed by the gas permeable bag and the dust collection bag, so that the dust in the air falls into the dust collection bag during the backflow process, and the air with reduced dust content is discharged through the mesh of the gas permeable bag.
[0004] Taiwan Patent No. M284435 also points out that a "industrial filter cartridge" for use in a working place has been developed by those skilled in the art. The "industrial filter cartridge" is composed of a base plate, a folded filter paper cartridge, a support body and a flange. A receiving groove is provided on the base plate to embed one end of the folded filter paper cartridge, and a ring-shaped groove is formed on the flange to embed the other end of the folded filter paper cartridge. Then, the support body is inserted into the central hole of the folded filter paper cartridge, and the support body and the groove are used to clamp the filter paper cartridge, so that the folded filter paper cartridge can filter fine dust.
[0005] Due to the structure of the "industrial filter cartridge", the entire structure including the base plate, the folded filter paper cartridge, the support body and the flange must be discarded when the filter paper cartridge is replaced. This not only wastes resources but also increases costs. Moreover, the base plate, the support body and the flange cannot be recycled and burned, becoming garbage that is difficult to dispose of and occupies space.
[0006] Taiwan Patent No. M284435 proposes a structure improvement of the filter cartridge of an industrial dust collector. The integrally fixed and combined filter cartridge structure is divided into a base plate, a folded filter paper cartridge, a support body and a flange, which are combined into an independent element. The end of the folded filter paper cartridge is hardened by impregnation treatment, so that it can be embedded in the inner groove of the base plate and the flange, respectively. Then, the assembly is positioned by screwing and locking, so that the folded filter paper cartridge can be replaced individually.
[0007] The installation mode of the raised filter paper bag or the separately replaceable folded filter paper cylinder cannot solve the problems of material waste and environmental burden. Utility model content
[0008] Therefore, the dust collector is composed of a cover plate, a dust collecting cylinder, a bottom plate seat and a supporting cylinder. The supporting cylinder is arranged inside the dust collecting cylinder. The surface of the supporting cylinder is provided with a plurality of through holes. The upper end and the lower end of the dust collecting cylinder are respectively provided with a cover plate and a bottom plate seat. The dust collecting cylinder is surrounded by a plurality of folded and overlapped sheet filter materials with mesh holes. The outer surface of the filter material is provided with a dust collecting film with air permeability. The surface of the supporting cylinder is provided with a buffer filter material between the dust collecting film. The surface of the filter material of the dust collecting cylinder is attached with a dust collecting film with air permeability and elasticity. The dust collecting film is locally connected with the surface of the filter material. The dust collecting film can be pushed outward and shaken by the gas. When the gas disappears, the dust collecting film automatically shrinks and reattaches to the surface of the filter material.
[0009] According to the dust collector, the air permeation hole of the dust collecting film is smaller than the mesh hole of the filter material. When the dust in the air adheres to the surface of the dust collecting film to a certain amount, the filter material is exhausted from the inside of the dust collecting cylinder. The dust collecting film is pushed outward and shaken. The dust adhering to the surface of the dust collecting film is shaken off. The buffer filter material inside the dust collecting film is annular and arranged at the inner side of the dust collecting film. The average stress of the filter core is increased. This is the second purpose of the utility model.
[0010] According to the dust collector, the buffer filter material is an elastic material. The dust in the air can be quickly collected in the predetermined collection equipment by the dust collecting film with air permeability and elasticity. The material cost can be avoided. The buffer filter material inside the dust collecting film can reduce the phenomenon that the backwash wave directly impacts the outer film. The service life of the dust collector is increased. This is the third purpose of the utility model.
[0011] Optionally, the buffer filter material is a film material.
[0012] Optionally, the buffer filter material and the outer cylinder surface of the supporting cylinder are attached.
[0013] Optionally, the dust collecting film can be pushed outward and shaken to shake off the dust adhering to the surface of the dust collecting film when the dust collecting cylinder is exhausted from the inside of the supporting cylinder. When the gas disappears, the dust collecting film can automatically shrink and reattach to the surface of the filter material.
[0014] The dust collector of the utility model has the advantages that the dust collecting film can be repeatedly used, the environmental protection problem can be reduced, the filter efficiency can be improved by the added buffer filter material, the environmental protection problem is also helpful, and the utility model also has the purpose of improving the filter efficiency.
[0015] The utility model has the advantages that:
[0016] The dust collecting film with the air permeability and elasticity is pasted on the outer surface of the filter material of the dust collecting cylinder, the buffer filter material is arranged on the inner side, the dust in the air is attached to the surface of the dust collecting film to a certain amount, the filter material is exhausted from the inside of the dust collecting cylinder, the dust collecting film is pushed out by the air and shakes outward, and the dust attached to the surface of the dust collecting film is shaken off.

[0041] The dust collector of this utility model, such as Figures 1 to 4 As shown, the dust collector 10 is composed of a cover plate 100, a dust collection cylinder 200, a base 300, a support cylinder 400, a dust collection membrane 500 and a buffer filter material 600.
[0042] Similarly, Figures 1 to 4 As shown, the cover plate 100 and the base 300 are respectively disposed at the upper and lower ends of the dust collection cylinder 200 to clamp and fix the dust collection cylinder 200 from the top and bottom. The cover plate 100 has a through hole 101 in the center, which allows gas to enter and exit. Inside the base 300, opposite to the through hole 101 of the cover plate 100, there is an arc-shaped convex plate 301 that arches upwards in an arc shape. A small through hole 302 is provided at the high center of the arc-shaped convex plate 301. Between the edge of the arc-shaped convex plate 301 and the edge of the base 300, there is an annular groove 303 for placing the dust collection cylinder 200.
[0043] Similarly, Figures 1 to 4 As shown, the outer edge of the arc-shaped protrusion 301 of the chassis base 300 provides support for the upright sleeve 400. The surface of the support sleeve 400 is densely covered with multiple vent holes 401, through which gas can enter and exit.
[0044] A dust collection cylinder 200 is provided around the support cylinder 400. The dust collection cylinder 200 is formed by bending and overlapping a filter material 201 with dense mesh to form a cylindrical body. The outer surface of the filter material 201 is covered with the dust collection membrane 500. The buffer filter material 600 is located inside the dust collection membrane 500 and between the support cylinders 400.
[0045] Similarly, Figures 1 to 4As shown, the dust collecting film 500 is made of elastic material. The dust collecting film 500 is in the form of a thin film, which is air-permeable and elastic, and the air-permeable holes thereof are smaller than the mesh holes of the filter material 201, so as to block the dust or particles in the air. The dust collecting film 500 is connected with the peripheral bending point 202 of the filter material 201, so as to be attached to the surface of the filter material 201 and to be bounced outwards and then elastically retracted in time.
[0046] In implementation, as shown in Figure 5 When the dust collecting cylinder 200 is placed in a working place, the dust 6 in the air will gradually adhere to the surface of the dust collecting film 500. When the supporting cylinder 400 rotates, the plurality of air holes 401 thereof will generate a backwash wave, and the impact of the backwash wave will be reduced due to the buffer filter material 600 between the dust collecting cylinder 200 and the dust collecting film 500.
[0047] Please refer to Figure 6 and Figure 7 When the surface of the dust collecting film 500 accumulates a certain amount of dust, the original gas continuously enters the inside of the supporting cylinder 400 from the through hole 101 of the cover plate 100, and the gas entering the inside of the supporting cylinder 400 will be blocked by the arc-shaped convex plate 301 of the bottom seat 300, so as to form a swirling vortex in the inside of the supporting cylinder 400. After accumulating to a certain pressure, the gas is discharged from the air holes 401 of the supporting cylinder 400 and the mesh holes of the filter material 201. Due to the effect of the buffer filter material 600, the strength of the swirling vortex in the inside of the supporting cylinder 400 is greatly reduced. The gas discharged from the mesh holes of the filter material 201 further impacts the dust collecting film 500 attached to the surface of the filter material 201, so that the dust collecting film 500 is bounced outwards, the dust attached to the surface of the dust collecting film 500 is shaken off and falls into the collecting device (not shown in the figure). When the gas that pushes the dust collecting film 500 to be bounced outwards disappears, the dust collecting film 500 is elastically retracted and then attached to the surface of the filter material 201 again. In this way, the service life of the dust collector is greatly increased.
[0048] Therefore, the dust collector of the present application can gradually and evenly collect the dust in the air into the collecting device for improving the air quality in the working place, so as to not only improve the cost of material use, but also further avoid the environmental problem.
[0049] The above description is only the best specific embodiment of the present application, and the structural features of the present application are not limited to this. Any person skilled in the art can easily think of changes or modifications in the field of the present application, which can be covered by the patent range of the present application.
