Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust collector technology, specifically to a post-dust collector filter element. Background Technology
[0002] In industrial production and various scenarios requiring gas purification, post-dust collectors play a crucial role. They can effectively remove dust particles and other impurities from the gas, ensuring the normal operation of subsequent process equipment and the cleanliness and safety of the production environment. As the core component of the post-dust collector, the performance of the filter element directly determines the filtration effect and service life of the dust collector.
[0003] In traditional post-dust collectors, as dust-laden gas continuously passes through the filter media during the filtration process, dust gradually accumulates on the surface, forming a thick dust layer. This dust layer reduces the air permeability of the filter media, increasing the resistance to gas flow and consequently affecting the dust collector's processing air volume and filtration efficiency. To restore the air permeability of the filter media, it is usually necessary to clean the dust on the filter element regularly. For some small post-dust collectors, mechanical cleaning is typically used, where manual or mechanical shaking causes the filter element to vibrate, thus shaking off the dust adhering to the filter media. However, manual shaking is inefficient, while mechanical shaking consumes a lot of energy.
[0004] Therefore, we have designed a post-dust collector filter element to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a post-dust collector filter element to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a post-dust collector filter element, comprising a beater structure, wherein the beater structure is disposed inside a cylindrical frame, comprising a rotating shaft, elastic plates, rubber blocks, and guide plates. The rotating shaft is vertically disposed at the axis of the frame, and multiple strip-shaped elastic plates are fixed to the side of the rotating shaft. A rubber block is fixed to the end of each elastic plate, and the rubber block is in close contact with the inner wall of the frame. Multiple vertical guide plates are fixed to the inner wall of the frame. A connector and a bottom seal are fixed to the top and bottom of the frame, respectively. An air outlet is opened at the center of the connector, and a cross is fixed to the inner side of the air outlet. The rotating shaft is rotatably mounted between the cross and the bottom seal via a bearing. A handwheel is installed at the top of the rotating shaft, and filter material is wrapped around the outside of the frame.
[0007] As a preferred embodiment of this utility model, the filter material has seven layers, with the innermost and outermost three layers being PP filter membranes and the remaining three layers being GF filter membranes.
[0008] As a preferred embodiment of this utility model, both ends of the filter material are sealed with sealant between the connector and the bottom seal.
[0009] As a preferred embodiment of this utility model, the top of the connector and the bottom of the sealing cap are both pre-set with mounting holes.
[0010] As a preferred embodiment of this utility model, the length of the elastic plate is greater than the inner radius of the skeleton, and the elastic plate is bent and arranged inside the skeleton.

[0013] Compared with the prior art, this utility model provides a post-dust collector filter element, which has the following characteristics:
[0014] Beneficial effects:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-4 In this embodiment: a post-dust collector filter element includes a beating structure disposed inside a cylindrical frame 5. The beating structure includes a rotating shaft 1, elastic plates 2, rubber blocks 3, and guide plates 4. The rotating shaft 1 is vertically positioned along the axis of the frame 5. Multiple strip-shaped elastic plates 2 are fixed to the side of the rotating shaft 1. The length of each elastic plate 2 is greater than the inner radius of the frame 5. The elastic plates 2 are bent within the frame 5. A rubber block 3 is fixed to the end of each elastic plate 2, and the rubber block 3 is in close contact with the inner wall of the frame 5. Multiple vertical guide plates 4 are fixed to the inner wall of the frame 5, with an angle of approximately 45°-60° between the guide plates 4 and the inner wall of the frame 5. The plates 4 are arranged in a ring array inside the frame 5. The top and bottom of the frame 5 are fixed with connectors 6 and bottom seals 7 respectively. The top of connectors 6 and the bottom of bottom seals 7 are pre-set with mounting holes. An air outlet is opened in the center of connectors 6, and a cross 8 is fixed inside the air outlet. The rotating shaft 1 is rotatably installed between the cross 8 and the bottom seal 7 through bearings. A handwheel 9 is installed at the top of the rotating shaft 1. The outer side of the frame 5 is wrapped with filter material 10. Both ends of the filter material 10 are sealed with sealant to connectors 6 and bottom seals 7. The filter material 10 has seven layers. The innermost and outermost three layers are PP1 filter membranes, and the remaining three layers are GF filter membranes. Each two layers of filter material 10 are separated by wire mesh.
[0023] Utility Model 1: This embodiment provides a post-dust collector filter element, which includes a frame 5 and a beater structure. The frame 5 is cylindrical, with a connector 6 and a bottom seal 7 fixed at the top and bottom respectively. Filter material 10 is wrapped around the outside of the frame 5. An air outlet is opened at the center of the connector 6, and a cross 8 is fixed inside the air outlet. The beater structure is located inside the frame 5 and specifically consists of a rotating shaft 1, elastic plates 2, rubber blocks 3, and guide plates 4. The rotating shaft 1 is vertically positioned at the axis of the frame 5 and is rotatably mounted between the cross 8 and the bottom seal 7 via bearings. A handwheel 9 is installed at the top of the rotating shaft 1 for easy manual rotation by the user. Multiple strip-shaped elastic plates 2 are fixed to the side of the rotating shaft 1. The length of the elastic plates 2 is greater than the inner radius of the frame 5 and is bent inside the frame 5. A rubber block 3 is fixed to the end of each elastic plate 2. The rubber block 3 is attached to the frame. The inner walls of the frame 5 are in close contact. Multiple vertical guide plates 4 are fixed on the inner walls of the frame 5. The angle between the guide plates 4 and the inner walls of the frame 5 is about 45°-60°. The multiple guide plates 4 are arranged in a ring array inside the frame 5. When the rotating shaft 1 rotates, multiple elastic plates 2 and rubber blocks 3 will rotate with it. During the rotation, the rubber blocks 3 pass through the guide plates 4 and move towards the inner side of the frame 5 under the guidance of the guide plates 4. At the same time, the elastic plates 2 bend and deform, and the elastic potential energy increases until the rubber blocks 3 leave the guide plates 4. Under the elastic force of the elastic plates 2, the rubber blocks 3 move outward quickly and beat the inner walls of the frame 5, causing the frame 5 and the filter material 10 wrapped on the outside of the frame 5 to vibrate, thereby shaking off the dust attached to the surface of the filter material 10. With the cooperation of multiple elastic plates 2 and rubber blocks 3, the filter element can vibrate at a high frequency, so that the dust attached to the surface of the filter material 10 can be shaken off quickly.
[0024] Example 2: Based on Example 1, this example further optimizes the structure of the filter media 10. The filter media 10 wrapped around the outside of the skeleton 5 has seven layers. The innermost and outermost three layers are PP1 filter membranes, and the remaining three layers are GF filter membranes. Each pair of filter media 10 is separated by a wire mesh to prevent the filter media 10 from sticking together and affecting the filtration effect. Both ends of the filter media 10 are sealed with the connector 6 and the bottom seal 7 with sealant to ensure that the gas can only be filtered through the filter media 10 and discharged from the gas outlet.
[0025] Example 3: Based on Example 1, this example optimizes the materials of each component of the filter element. The elastic plate 2 is made of alloy spring steel, the guide plate 4 is made of stainless steel plate, the frame 5 is made of stainless steel powder or copper powder sintered, and the connector 6 and the bottom seal 7 are both made of round steel. The top of the connector 6 and the bottom of the bottom seal 7 are both pre-set with mounting holes to facilitate the installation of the filter element into the post-dust collector.
[0026] Usage Procedure: First, install the filter element into the post-dust collector. After installation, dust-laden gas enters from the outside of the filter element and must pass through the seven layers of filter media 10 wrapped around the frame 5 for filtration. The innermost and outermost three layers are PP1 filter membranes, and the remaining three layers are GF filter membranes. Each pair of filter media 10 layers is separated by a wire mesh, ensuring smooth gas passage while effectively intercepting dust and preventing the filter media 10 from sticking together and affecting the filtration effect. During the filtration process, to prevent excessive dust accumulation on the surface of the filter media 10 from affecting filtration efficiency, the dust adhering to the surface of the filter media 10 needs to be cleaned regularly. When cleaning, first turn off... The dust collector is closed. By turning the handwheel 9, the rotating shaft 1 is driven to rotate. When the rotating shaft 1 rotates, the multiple elastic plates 2 fixed on its side will rotate along with the rubber blocks 3. When the rubber blocks 3 pass through the area of the guide plate 4, the rubber blocks 3 will move towards the inside of the frame 5 under the guidance of the guide plate 4. At the same time, the elastic plates 2 bend and the elastic potential energy increases until the rubber blocks 3 leave the guide plate 4. Under the elastic force of the elastic plates 2, the rubber blocks 3 move outward quickly and beat the inner wall of the frame 5, causing the frame 5 and the filter material 10 wrapped on the outside of the frame 5 to vibrate, thereby shaking off the dust attached to the surface of the filter material 10.
[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
