Abstract
Description
Technical Field
[0001] The utility model relates to the field of waste gas treatment, and more specifically, it relates to a dust removal and ventilation environmental protection device. Background Technique
[0002] A dust removal and ventilation environmental protection device is a device used to filter solid particles in an air flow. Generally, it consists of a fan, a flow channel, and a filter screen. The fan guides the air flow to flow, and the air flow carries the particles to flow in the flow channel. When the air flow passes through the filter screen, the particles are intercepted by the filter screen to achieve the capture of solid particles in the air flow. However, the maximum value of the effective filtration area of the existing filter screen depends on the cross-sectional area of the flow channel, resulting in low filtration efficiency.
[0003] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

One end of the pipeline is fixedly connected to a fan, and the other end of the pipeline is detachably connected to a mesh frame. The inner side of the mesh frame is fixedly connected to a filter screen. The filter screen is in a frustum shape. A support frame is fixedly connected inside the pipeline, and the end of the filter screen is detachably connected to the support frame.
[0006] The present utility model is further provided as follows: A connection block is fixedly connected to the end of the filter screen. The support frame includes a magnetic block and several support feet. The two ends of the support feet are respectively fixedly connected to the magnetic block and the pipeline, and the magnetic block is attracted to the connection block.
[0007] The present utility model is further provided as follows: The filter screen is in a quadrangular frustum shape, and a reinforcing edge is fixedly connected to the outer edge of the filter screen.
[0008] The present utility model is further provided as follows: On the projection plane along the length direction of the pipeline, the projection of the reinforcing edge coincides with the projection of the support feet.
[0009] The present utility model is further provided as follows: A through hole is penetrated through the connection block, and an opening communicating with the through hole is penetrated through the magnetic block.
[0010] The present utility model is further provided as follows: Several convex blocks are fixedly connected to the end of the pipeline away from the fan, and the convex blocks are embedded in the side of the mesh frame close to the pipeline.
[0011] In summary, the utility model has the following beneficial effects: The filter screen bulges towards the direction of the fan in the pipeline to form a frustum shape, increasing the surface area of the filter screen, that is, improving the effective filtering area of the filter screen, thereby improving the filtering efficiency. The support frame plays a supporting role for the filter screen, reducing the shaking of the filter screen in the air flow. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following combines the drawings and embodiments to describe the utility model in detail.
[0017] Embodiment: A dust removal and ventilation environmental protection device, as Figure 1 , Figure 2 , Figure 3 shown, includes a pipeline 1. One end of the pipeline 1 is fixedly connected with a fan 2, and the other end of the pipeline 1 is detachably connected with a mesh frame 3. The inner side of the mesh frame 3 is fixedly connected with a filter screen 4. The filter screen 4 is in a frustum shape. A support frame is fixedly connected in the pipeline 1. The end of the filter screen 4 is detachably connected with the support frame. A plurality of convex blocks 11 are fixedly connected to the end of the pipeline 1 away from the fan 2, and the convex blocks 11 are embedded in the side of the mesh frame 3 close to the pipeline 1.
[0018] Specifically, the pipeline 1 is a square pipe. The mesh frame 3 and the filter screen 4 are welded. A plurality of filtering holes are formed in the filter screen 4. The filter screen 4 bulges towards the direction of the fan 2 in the pipeline 1 to form a frustum shape, increasing the surface area of the filter screen 4, that is, improving the effective filtering area of the filter screen 4, thereby improving the filtering efficiency. The support frame plays a supporting role for the filter screen 4, reducing the shaking of the filter screen 4 in the air flow. Four embedding grooves are formed in the side of the mesh frame 3 close to the fan 2, and the embedding grooves penetrate through the side wall of the mesh frame 3. There are four convex blocks 11 on the pipeline 1, and the four convex blocks 11 are respectively embedded in the four embedding grooves. The convex blocks 11 play a limiting role for the mesh frame 3, preventing the mesh frame 3 from shaking. The depth of the embedding groove is greater than the thickness of the convex block 11. When it is necessary to remove the filter screen 4, the mesh frame 3 can be pried out through the embedding groove.
[0019] Such as Figure 1 , Figure 2 , Figure 3As shown, a connecting block 5 is fixedly connected to the end of the filter screen 4. The support frame includes a magnetic block 6 and a plurality of support feet 7. The two ends of the support feet 7 are respectively fixedly connected to the magnetic block 6 and the pipeline 1. The magnetic block 6 is attracted to the connecting block 5. The filter screen 4 is in the shape of a frustum of a pyramid. A reinforcing edge 8 is fixedly connected to the outer edge of the filter screen 4. On the projection plane along the length direction of the pipeline 1, the projection of the reinforcing edge 8 coincides with the projection of the support feet 7. A through hole 9 is provided through the connecting block 5, and an opening 10 communicating with the through hole 9 is provided through the magnetic block 6.
[0020] Specifically, the connecting block 5 with the through hole 9 is in the shape of a square frame, and the magnetic block 6 with the opening 10 is also in the shape of a square frame. The connecting block 5 and the magnetic block 6 are attracted to each other, which improves the connection strength between the filter screen 4 and the pipeline 1. At the same time, the magnetic connection facilitates the disassembly and assembly of the filter screen 4 and improves the maintenance efficiency. The through hole 9 and the opening 10 further increase the effective filtering area of the filter screen 4. The four reinforcing edges 8 are integrally formed with the filter screen 4, which increases the strength of the filter screen 4. Along the air flow direction, the magnetic block 6 is connected to the pipeline 1 through the four support feet 7. The projection of the reinforcing edge 8 coincides with the projection of the support feet 7, which reduces the influence of the support feet 7 on the air flow.
[0021] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. Any technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
