Description

Technical Field

[0001] This utility model relates to the field of filter bag technology, specifically to a multi-layer composite dust removal filter bag. Background Technology

[0002] Multi-layer composite dust collector filter bags consist of a bottom layer, a base layer, a top layer, and other functional layers, and are commonly used in industries such as chemical, building materials, metallurgy, power, and food.

[0003] A search revealed a multi-layer composite dust collector filter bag in Chinese application number CN202222330929.3, belonging to the technical field of dust collector filter bags. The bag includes a filter bag body, a connecting plate at the upper end of the filter bag body, several reinforcing rods at the lower end of the connecting plate, and a support assembly on the outer side of the filter bag body. In this prior art, by setting the support assembly, several support rings and vertical rods are provided on the outer surface of the filter bag body, which can play a certain limiting and supporting role, increasing the strength of the filter bag body. This makes the filter bag less prone to deformation and damage when scraped by the scraper, and the connecting support rods can support the support rings, making its structure more stable.

[0004] In the aforementioned prior art, a motor and transmission assembly installed inside the filter bag drive a rotating rod to rotate, which in turn drives a cleaning brush to rotate, thus cleaning the inside of the filter bag. The motor is mounted on a cover plate at the top of the filter bag, and the cover plate is connected to the filter bag frame by bolts. Although this connection method is relatively stable, when the cleaning brush needs to be replaced later, each bolt must be unscrewed, and then the cover plate, motor, rotating rod, and cleaning brush must be removed from the filter bag before the cleaning brush can be replaced. The replacement method is cumbersome and requires the assistance of tools. In addition, the cleaning brush and rotating rod are assembled by welding, and when replacing them, the rotating rod and cleaning brush must be separated from the motor for overall replacement, resulting in high replacement costs.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a multi-layer composite dust collector filter bag, including a frame 1, a filter bag 11 fixedly connected to the lower side of the frame 1, and a protective cover 12 sleeved on the outer side of the filter bag 11. The upper end of the protective cover 12 is fixedly connected to the frame 1, and a replacement component 2 is provided on the inner side of the frame 1. The replacement component 2 includes a cover plate 21 inserted into the inner side of the frame 1, and a sealing gasket 22 is fixedly connected to the lower side of the cover plate 21. The lower side of the sealing gasket 22 is attached to the frame 1, and an air inlet 13 is fixedly connected to one end of the cover plate 21. The replacement component 2 can be used to quickly remove the filter bag and replace the cleaning brush 27 independently, which improves the convenience of disassembly and reduces the replacement cost.

[0029] like Figure 2 and Figure 3As shown, a motor 23 is fixedly connected to the middle position of the cover plate 21, and a rotating rod 24 is fixedly connected through the output shaft of the motor 23 through the cover plate 21. The upper end of the rotating rod 24 is rotatably connected to the cover plate 21, and fixed brackets 25 are fixedly connected to both ends of the rotating rod 24. The rotating rod 24 and the fixed brackets 25 are rotated by the output shaft of the motor 23.

[0030] like Figure 4 As shown, a plate 26 is inserted into the end of the fixed frame 25 away from the rotating rod 24, and a cleaning brush 27 is fixedly connected to the end of the plate 26 away from the fixed frame 25. The side of the cleaning brush 27 away from the plate 26 is in contact with the inside of the filter bag 11. The plate 26 drives the cleaning brush 27 to rotate, so that the cleaning brush 27 cleans the inside of the filter bag 11.

[0031] like Figure 4 As shown, a locking block 28 is inserted into the end of the insert plate 26 away from the cleaning brush 27, and a first spring 29 is fixedly connected to the end of the locking block 28 inserted into the insert plate 26. The end of the first spring 29 away from the locking block 28 is fixedly connected to the insert plate 26. When the insert plate 26 is inserted into the fixing frame 25, the fixing frame 25 squeezes the locking block 28. After the locking block 28 is squeezed, it compresses the first spring 29. After the insert plate 26 is inserted, the elastic potential energy of the first spring 29 pushes the locking block 28 to pop out and insert it into the fixing frame 25 to lock and fix the insert plate 26.

[0032] like Figure 4 As shown, positioning rods 210 are fixedly connected to both ends of the frame 1, and a rotating plate 211 is rotatably connected to the upper end of the positioning rods 210. A pressure block 212 is fixedly connected to one end of the rotating plate 211 near the positioning rods 210, and the lower side of the pressure block 212 is in contact with the cover plate 21. By using the rotating plate 211 to drive the pressure block 212 to rotate under the restriction of the positioning rods 210, the pressure block 212 can be used to lock and restrict the cover plate 21.

[0033] like Figure 4 As shown, a retaining plate 213 is inserted inside the end of the rotating plate 211 away from the positioning rod 210, and a second spring 214 is fixedly connected to both ends of the retaining plate 213. The upper end of the second spring 214 is fixedly connected to the rotating plate 211, and a pull block 215 is fixedly connected to the middle position of the upper side of the retaining plate 213. A pull ring 216 is fixedly connected to the upper end of the pull block 215. Pulling the pull ring 216 can pull the retaining plate 213 upward through the pull block 215 to compress the second spring 214, thereby allowing the retaining plate 213 to pull the insert block 217 and the ball 218 upward.

[0034] like Figure 4As shown, a plug 217 is fixedly connected to the lower side of the card plate 213, and the lower end of the plug 217 is inserted into the cover plate 21. A ball bearing 218 is inserted into the inner side of the lower end of the plug 217. When the rotating plate 211 pushes the pressure block 212 to rotate, the plug 217 synchronously drives the ball bearing 218 to rotate. The ball bearing 218 rotates by rolling with the cover plate 21 and the frame 1 to assist the rotating plate 211 in rotating.

[0035] Working principle: When cleaning the inside of the filter bag 11 is required, the motor 23 is started to drive the rotating rod 24 and the fixing frame 25 to rotate. The fixing frame 25 drives the insert plate 26 and the cleaning brush 27 to rotate, thereby cleaning the inside of the filter bag 11 through the cleaning brush 27. After cleaning, the motor 23 is turned off. When the cleaning brush 27 needs to be replaced, the pull rings 216 on both sides are pulled first. After the pull rings 216 are pulled, the pull block 215 drives the clamping plate 213 to move upward and compress the second spring 214. After the clamping plate 213 is pulled upward, the insert block 217 and the ball bearing 218 are pulled upward simultaneously. After the insert block 217 and the ball bearing 218 are pulled out of the cover plate 21, this... Under the constraint of the positioning rod 210, the rotating plate 211 can be rotated. After the rotating plate 211 rotates, it drives the pressure block 212 to rotate and disengage from the cover plate 21. Then, the pull ring 216 is released, and the elastic potential energy of the second spring 214 pushes the clamping plate 213 and the insert block 217 to move down. At this time, the insert block 217 pushes the ball 218 to fit against the frame 1. Then, the motor 23 is pulled to drive the cover plate 21, sealing gasket 22, rotating rod 24 and fixing frame 25 to pull out the filter bag 11. After the inserting plate 26 and cleaning brush 27 are pulled out of the filter bag 11, the clamping blocks 28 inserted inside both ends of the fixing frame 25 can be pressed. After the clamping blocks 28 are pressed, they are inserted into the inserting plate 26. After compressing the first spring 29, the cleaning brush 27 can be pulled to pull the insert plate 26 out of the fixing frame 25 for replacement. The replaced cleaning brush 27 then pulls the insert plate 26 into the fixing frame 25. During insertion, the fixing frame 25 presses against the locking blocks 28 at both ends of the insert plate 26. The locking blocks 28, after being compressed, are inserted into the insert plate 26, compressing the first spring 29. After insertion, the elastic potential energy of the first spring 29 pushes the locking blocks 28 out and into the fixing frame 25 to lock and fix the insert plate 26. Then, the motor 23 drives the rotating rod 24 and the fixing frame 25 into the filter bag 11. The cover plate 21 and the sealing gasket 22 are then inserted into the frame. After the frame 1 is engaged, the rotating plates 211 on both sides can be moved. After the rotating plates 211 are moved, they drive the pressure block 212 and the insertion block 217 to rotate under the restriction of the positioning rod 210. The insertion block 217 drives the ball 218 to move. During the movement, the ball 218 rolls in contact with the frame 1 and the cover plate 21. The rolling of the ball 218 assists the movement of the insertion block 217 and the pressure block 212. When the insertion block 217 moves into the slots opened at both ends of the cover plate 21, the elastic potential energy of the second spring 214 pushes the insertion block 217 and the ball 218 to move down and insert into the slots for fixation. The pressure block 212 is used to fix the cover plate 21.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
