Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a filter disc. Background Technology

[0002] Filter discs are key components in air filtration systems, primarily used to capture particulate matter in the air. They are commonly found in precision air conditioning, fresh air systems, clean rooms, and industrial ventilation equipment. Their core function is to purify airflow, protect downstream equipment, and maintain environmental cleanliness.

[0003] Chinese Patent CN221084809U discloses a filter disc in a filter, including a filter disc body, a limiting rod fixedly installed on the inner wall of the filter disc body, a return spring installed inside the filter disc body, a filter screen fixedly installed at the bottom of the filter disc body, a filter disc mounting block fixedly installed on the side of the filter disc body, and a cleaning component installed inside the filter disc body, with a cleaning scraper fixedly installed at the bottom of the cleaning component. This invention uses a dirt collection box. After the filter disc body has been used for a period of time, pulling the handle to the left allows the cleaning component to slide to the left, causing the cleaning scraper to slide to the left against the top of the filter screen. The sliding of the cleaning scraper scrapes the scale covering the top of the filter screen to the left, facilitating regular cleaning of the filter disc body.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: due to the difficulty in disassembling and installing the existing filter discs, the cleaning work of the filter discs is also quite troublesome. Not only is the cleaning effect of the filter discs poor, but it also increases the time consumed in cleaning the filter discs. At the same time, it cannot protect the filter discs, which makes the filter discs easy to be damaged when subjected to large impact forces. Utility Model Content

[0005] The purpose of this invention is to address the problems in the prior art where filter discs cannot be automatically and effectively cleaned and cannot be buffered and protected, and to propose a new type of filter disc.

[0006] The technical solution of this utility model is as follows: a filter disc, including a mounting plate; and further comprising:

[0007] Automatic cleaning mechanism, located on the side of the mounting plate, is used to perform comprehensive automatic cleaning of the filter discs.

[0008] A buffer assembly is located inside the automatic cleaning mechanism to cushion and protect the filter disc when the impact force is too great.

[0009] The cleaning brush is mounted on an automatic cleaning mechanism. The bottom of the cleaning brush has a filter disc body. The cleaning brush moves back and forth under the drive of the automatic cleaning mechanism, and the filter disc body rotates under the drive of the automatic cleaning mechanism, so that the cleaning brush can clean the filter disc body in all directions.

[0010] Preferably, the automatic cleaning mechanism includes a rotating component and a reciprocating cleaning component;

[0011] The rotating assembly is located on the side of the mounting plate and is used to drive the filter disc body to rotate and provide power for the reciprocating cleaning assembly.

[0012] The reciprocating cleaning component is located on the side of the rotating component and is used to drive the cleaning brush to make a reciprocating motion.

[0013] Preferably, the rotating assembly includes a motor, a rotating shaft, a circular gear, and a gear ring;

[0014] The motor is located on the side of the mounting plate, the first rotating shaft is located at the output end of the first motor, the spur gear is located at the end of the first rotating shaft away from the first motor, the gear ring is located on the side of the spur gear and the spur gear and the gear ring mesh with each other, the inner side of the gear ring is provided with a mounting ring, the bottom of the mounting ring is rotatably provided with a support frame, and the inner side of the mounting ring is provided with a rotating frame.

[0015] Preferably, the reciprocating cleaning assembly includes a timing pulley one, a timing belt, and a timing pulley two;

[0016] Synchronous pulley one is located on the outside of rotating shaft one, synchronous belt is located on the outside of synchronous pulley one, synchronous pulley two is located at the end of synchronous belt away from synchronous pulley one, rotating shaft two is located at the axis of synchronous pulley two, a fixed cylinder is rotatably mounted at the end of rotating shaft two, the end of fixed cylinder away from rotating shaft two is connected to the side of mounting plate, rotating shaft two, a sleeve is rotatably mounted on the outside of rotating shaft two, rotating rod one is located at the top of rotating shaft two, rotating rod two is rotatably mounted at the end of rotating rod one away from rotating shaft two, a connecting shaft is rotatably mounted at the end of rotating rod two away from rotating rod one, a sliding block is located on the outside of connecting shaft, a fixed frame is slidably mounted on the outside of sliding block, and a connecting block is located at the end of fixed frame away from sleeve.

[0017] Preferably, the buffer assembly includes a hydraulic pipe, a piston plate, and a connecting rod;

[0018] The hydraulic pipe is located at the top of the rotating frame, the piston plate is slidably located inside the hydraulic pipe, the connecting rod is located at the top of the piston plate, and a spring is located on the outside of the connecting rod.

[0019] Preferably, a diffuser is rotatably provided on the side of the mounting ring, and a dust collection box is provided at the bottom of the diffuser.

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] 1. With the automatic cleaning mechanism, the motor drives the filter disc body to rotate through the sprocket and gear ring. At the same time, the motor drives the cleaning brush to move back and forth through the synchronous wheel one and synchronous wheel two. This allows each area of ​​the filter disc surface to be exposed to the cleaning brush in turn, avoiding the formation of stubborn accumulation of pollutants in fixed areas due to long-term contact. It also covers all radial positions on the surface of the filter disc, ensuring that each fan-shaped area is brushed. In the collaborative cleaning mode, the rotation and movement are carried out simultaneously, which can shorten the cleaning time and improve the cleaning efficiency.

[0022] 2. By setting up buffer components and diffusers, the diffusers can reduce the impact force brought by material transportation through the gradually expanding internal space. The filter disc body moves when subjected to impact force, thereby appropriately absorbing the impact force through springs and hydraulic pipes, further reducing the impact force. This can avoid uneven material accumulation on the filter screen surface, forming "channels" or "dead zones" and reducing filtration efficiency. At the same time, it protects the filter disc body and prevents damage. Attached Figure Description

[0028] Example 1

[0029] like Figures 1-3As shown, the present invention proposes a filter disc, which includes a mounting plate 1, an automatic cleaning mechanism, a buffer assembly, and a cleaning brush 218.

[0030] An automatic cleaning mechanism is located on the side of the mounting plate 1 and is used to perform full automatic cleaning of the filter discs;

[0031] The buffer assembly is located inside the automatic cleaning mechanism to cushion and protect the filter disc when the impact force is too great.

[0032] The cleaning brush 218 is mounted on the automatic cleaning mechanism. The bottom of the cleaning brush 218 is equipped with a filter disc body 210. The cleaning brush 218 moves back and forth under the drive of the automatic cleaning mechanism, and the filter disc body 210 rotates under the drive of the automatic cleaning mechanism, so that the cleaning brush 218 can clean the filter disc body 210 in all directions.

[0033] The automatic cleaning mechanism includes a rotating component and a reciprocating cleaning component. The rotating component is located on the side of the mounting plate 1 and is used to drive the filter disc body 210 to rotate and provide power to the reciprocating cleaning component. The reciprocating cleaning component is located on the side of the rotating component and is used to drive the cleaning brush 218 to perform reciprocating motion. The rotating component includes a motor 201, a rotating shaft 202, a spur gear 207, and a gear ring 208. The motor 201 is located on the side of the mounting plate 1, the rotating shaft 202 is located at the output end of the motor 201, the spur gear 207 is located at the end of the rotating shaft 202 away from the motor 201, the gear ring 208 is located on the side of the spur gear 207 and the spur gear 207 and gear ring 208 mesh, and a mounting ring 209 is provided on the inner side of the gear ring 208. The inner side of the mounting ring 209 is slidably connected to the outer side of the filter disc body 210, and the bottom of the mounting ring 209... The mounting ring 209 is rotatably equipped with a support frame 211, and a rotating frame 220 is provided on the inner side of the mounting ring 209. The end of the support frame 211 away from the mounting ring 209 is connected to the side of the mounting plate 1. The support frame 211 is used to reinforce the position of the mounting ring 209. The upper and lower surfaces of the mounting ring 209 are provided with sliding grooves. When the motor 201 is started, the motor 201 drives the rotating shaft 202 to rotate. The rotating shaft 202 drives the spur gear 207 to rotate. The spur gear 207 drives the gear ring 208 to rotate. When the gear ring 208 rotates, it drives the filter disc body 210 to rotate through the mounting ring 209.The reciprocating cleaning assembly includes a first synchronous pulley 203, a synchronous belt 204, and a second synchronous pulley 205. The first synchronous pulley 203 is located outside the first rotating shaft 202, the synchronous belt 204 is located outside the first synchronous pulley 203, and the second synchronous pulley 205 is located at the end of the synchronous belt 204 away from the first synchronous pulley 203. A second rotating shaft 221 is located at the axis of the second synchronous pulley 205, and a fixed cylinder 219 is rotatably mounted at the end of the second rotating shaft 221. The end of the fixed cylinder 219 away from the second rotating shaft 221 is connected to the side of the mounting plate 1. A second rotating shaft 221 has a sleeve 206 rotatably mounted on its outer side. The outer side of the sleeve 206 is connected to the inner side of the rotating frame 220, and the outer side of the sleeve 206 is also connected to the axis of the filter disc body 210, which is located above the rotating frame 220. A first rotating rod 212 is mounted on the top of the second rotating shaft 221. A second rotating rod 213 is rotatably mounted on the end of the first rotating rod 212 away from the second rotating shaft. A connecting rod is rotatably mounted on the end of the second rotating rod 213 away from the first rotating rod 212. A connecting shaft 214 is connected to a sliding block 215 on its outer side. A fixing bracket 216 is slidably mounted on the outer side of the sliding block 215. The end of the fixing bracket 216 is connected to the outer side of the sleeve 206. A connecting block 217 is provided at the end of the fixing bracket 216 away from the sleeve 206. The outer side of the connecting block 217 is rotatably connected to the groove above the mounting ring 209. The bottom of the sliding block 215 is connected to the top of the cleaning brush 218. The rotating shaft 202 drives the synchronous wheel 203 to rotate. The synchronous wheel 203 rotates through the same... The stepper belt 204 drives the synchronous pulley 205 to rotate, the synchronous pulley 205 drives the rotating shaft 221 to rotate, the rotating shaft 221 drives the rotating rod 212 to rotate, and the rotating rod 212 drives the rotating rod 213 to rotate. Due to the restriction of the fixed frame 216, the sliding block 215 can only move along a straight line. Therefore, the sliding block 215 moves back and forth on the fixed frame 216 under the drive of the rotating rod 212 and the rotating rod 213, thereby driving the cleaning brush 218 to move back and forth on the filter disc body 210 for cleaning.

[0034] Example 2

[0035] like Figures 1-4 As shown, the present invention proposes a filter disc. Compared with Embodiment 1, this embodiment details the structure of the buffer assembly, the diffuser tube 4, and the dust collection box 5.

[0036] The buffer assembly includes a hydraulic pipe 301, a piston plate 302, and a connecting rod 303. The hydraulic pipe 301 is located on the top of the rotating frame 220. The piston plate 302 is slidably located inside the hydraulic pipe 301. The connecting rod 303 is located on the top of the piston plate 302. A spring 304 is located on the outside of the connecting rod 303. The hydraulic pipe 301 is filled with hydraulic oil. When the filter disc body 210 is impacted, the filter disc body 210 squeezes the connecting rod 303. The connecting rod 303 drives the piston plate 302 to slide inside the hydraulic pipe 301, thereby causing the internal hydraulic oil to move and flow back. At this time, the spring 304 is compressed, thereby consuming the impact energy and providing appropriate buffering for the filter disc body 210. A diffuser tube 4 is rotatably mounted on the side of the mounting ring 209. The diffuser tube 4 is in the shape of a truncated cone. The end of the diffuser tube 4 away from the mounting ring 209 is set to be open. A dust collection box 5 is set at the bottom of the diffuser tube 4. The bottom of the dust collection box 5 is connected to the mounting plate 1. The diffuser tube 4 can reduce the impact of water flow, thereby further protecting the filter disc body 210. The dust collection box 5 is used to collect the dust and debris cleaned by the cleaning brush 218.

[0037] In summary, when using this utility model, the open end of the diffuser 4 is connected to the pipe containing the material to be filtered. Then, the motor 201 is started and the material is introduced. During the filtration process, the filter disc body 210 is driven by the motor 201 to rotate the first shaft 202, which in turn drives the spur gear 207 to rotate. The spur gear 207 then drives the gear ring 208 to rotate. When the gear ring 208 rotates, it drives the filter disc body 210 to rotate via the mounting ring 209. At the same time, the first shaft 202 drives the first synchronous pulley 203 to rotate. The first synchronous pulley 203 drives the second synchronous pulley 205 to rotate via the synchronous belt 204. The second synchronous pulley 205 drives the second shaft 221 to rotate, which in turn drives the first rotating rod 212 to rotate. The first rotating rod 212 then drives the second shaft 221 to rotate. Rotating rod 213 causes sliding block 215 to move back and forth on fixed frame 216 under the drive of rotating rod 212 and rotating rod 213, thereby driving cleaning brush 218 to move back and forth on filter disc body 210 for cleaning. The cleaned impurities and dust are pushed to the bottom by cleaning brush 218 and fall into dust collection box 5. The diffuser 4 can reduce the impact force during the material receiving process, thereby protecting the filter disc. After the filter disc comes into contact with the material, it moves under the action of impact force, thereby driving piston plate 302 to slide in hydraulic pipe 301 through connecting rod 303, thereby causing the internal hydraulic oil to move back. At this time, spring 304 is compressed, thereby consuming the impact energy and further buffering the filter disc body 210.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
