Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically a self-cleaning filter scraper structure. Background Technology

[0002] A self-cleaning filter is a precision device that uses a filter screen to directly intercept impurities in water, removing suspended solids and particulate matter, reducing turbidity, purifying water quality, and reducing the generation of system dirt, algae, and corrosion, thereby purifying water and protecting the normal operation of other equipment in the system. Existing self-cleaning filters generally have a scraper structure installed internally. This scraper structure typically consists of a geared motor, a drive shaft, a connecting rod, and scrapers. The geared motor drives the drive shaft to rotate, which in turn rotates the connecting rod, which in turn has a scraper fixed to it. The rotating scraper scrapes off foreign objects from the filter screen, preventing clogging. However, the existing scraper structure is fixed and its effect is limited. When the scraper wears or is damaged, it is inconvenient to adjust or replace it in a timely manner, resulting in poor performance. Furthermore, replacing the scraper requires replacing the entire filter, which can lead to resource waste. Utility Model Content

[0003] The purpose of this invention is to provide a self-cleaning filter scraper structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A circular shell has multiple water inlet holes and multiple water outlet holes. A fixed frame is rotatably sleeved on the top of the outer side wall of the circular shell, and a support frame is rotatably sleeved on the bottom of the circular shell. A reduction motor is provided on the top of the circular shell, and the output end of the reduction motor is fixedly connected to the top of the circular shell. A conveying assembly is provided on the top of the circular shell.

[0007] Multiple scraper mechanisms are located on the outer side of the circular shell.

[0008] Furthermore, the conveying assembly includes a rotating shell, which is rotatably sleeved with the top of the outer wall of the circular shell, and multiple water inlets are located inside the rotating shell, with the outer side of the rotating shell connected to a fixed conveying pipe.

[0009] Furthermore, the scraper mechanism includes:

[0010] A connecting shell is disposed on the outside of the circular shell. A circular groove is provided on the connecting shell. An adjustment component is provided on the connecting shell, and a flushing component is provided on the outside of the connecting shell.

[0012] Multiple scraper bodies are slidably connected to the interior of the connecting shell, and the scraper bodies are provided with round holes.

[0013] Preferably, the positioning component includes:

[0014] A screw is rotatably connected to the interior of the connecting housing, with the top of the screw passing through the side wall of the connecting housing and extending into the interior of the circular groove;

[0015] A movable block is screwed into the screw, and the movable block is slidably connected to the inside of the connecting shell. The movable block is provided with multiple connecting grooves.

[0016] The movable rod is slidably connected to the interior of the connecting shell. The movable rod has multiple connecting grooves II. A connecting rod is rotatably connected inside the connecting groove II, and one end of the connecting rod is rotatably connected to the interior of the corresponding connecting groove I. A round rod is fixedly connected to the movable rod, and the round rod is slidably connected to the corresponding round hole.

[0017] Preferably, a hexagonal block is fixed to the top of the screw, and the hexagonal block is located inside the circular groove.

[0018] Preferably, the outer diameter of the round rod is the same as the inner diameter of the round hole.

[0019] Preferably, the rinsing assembly includes:

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. By setting multiple scraper mechanisms on the outside of the circular shell, and starting the reduction motor, the circular shell and multiple scraper mechanisms are rotated. The rotating scraper bodies facilitate the cleaning of the filter screen. By rotating the screw, the distance between the multiple scraper bodies and the filter screen can be adjusted, ensuring the scraper mechanism's cleaning effect on removing foreign objects from the filter screen. If an external water pump and delivery pipe are used, water can be delivered into the rotating shell. The circular shell and flushing components work together to spray water from multiple nozzles. The sprayed water can rinse the areas scraped by the scraper bodies, further improving the cleaning effect of the scraper mechanism and thus enhancing the practicality of the self-cleaning filter scraper structure.

[0024] 2. A round rod is fixed to the moving rod. When the scraper body is damaged, rotating the screw moves the scraper body and the round rod out of the connecting shell. Multiple scraper bodies can be easily removed by sliding them upwards. The sliding connection between the round hole and the round rod makes the installation of multiple scraper bodies simpler, more convenient, and faster. When replacing multiple scraper bodies, only the damaged scraper body needs to be replaced, avoiding the waste of resources. After replacement, reversing the screw moves the moving rod into the connecting shell, thereby resetting the replaced scraper body. The operation is simpler and more convenient.

The circular shell 100 is provided with a plurality of water inlet holes 101 and a plurality of water outlet holes 102. A fixing frame 110 is rotatably sleeved on the top of the outer side wall of the circular shell 100, and a support frame 140 is rotatably sleeved on the bottom of the circular shell 100. A reduction motor 120 is provided on the top of the circular shell 100, and the output end of the reduction motor 120 is fixedly connected to the top of the circular shell 100. A conveying assembly is provided on the top of the circular shell 100, and the plurality of scraper mechanisms 200 are provided on the outer side of the circular shell 100.

[0036] Specifically, when the self-cleaning filter scraper structure is installed on the self-cleaning filter, the fixing frame 110, the reduction motor 120, and the support frame 140 are fixedly connected to the self-cleaning filter. The fixing frame 110 and the reduction motor 120 facilitate the support and limiting of the circular shell 100 and the multiple scraper mechanisms 200. By starting the reduction motor 120, the circular shell 100 and the multiple scraper mechanisms 200 are driven to rotate. The multiple scraper mechanisms 200 facilitate the scraping off of foreign objects on the filter screen of the self-cleaning filter, thereby facilitating the self-cleaning of the filter. The distance between the scraper mechanism 200 and the filter screen can be adjusted as needed to ensure the scraping effect of the scraper mechanism 200. Furthermore, the conveying component is used in conjunction with the multiple scraper mechanisms 200 to rinse the filter screen, thereby improving the cleaning effect of the filter screen.

[0037] Example 1

[0038] like Figure 3-6As shown, in this embodiment, the scraper mechanism 200 includes: a connecting shell 210, multiple fixing rods 220, and multiple scraper bodies 230. The connecting shell 210 is disposed on the outside of the circular shell 100, and a circular groove 211 is formed on the connecting shell 210. An adjustment component is provided on the connecting shell 210, and a flushing component is provided on the outside of the connecting shell 210. One end of each of the multiple fixing rods 220 is fixedly connected to the connecting shell 210, and the other end of each of the multiple fixing rods 220 is fixedly connected to the circular shell 100. A conveying hole 221 is formed on the fixing rod 220, and the conveying hole 221 corresponds to the corresponding water outlet hole 102. The multiple scraper bodies 230 are slidably connected to the inside of the connecting shell 210, and a circular hole 231 is formed on the scraper body 230. The adjustment component includes: a screw 250, a moving block 260, and a moving rod. 270. The screw 250 is rotatably connected to the interior of the connecting shell 210. The top of the screw 250 passes through the side wall of the connecting shell 210 and extends into the interior of the circular groove 211. The moving block 260 is screwed to the screw 250 and slidably connected to the interior of the connecting shell 210. Multiple connecting grooves 261 are provided on the moving block 260. The moving rod 270 is slidably connected to the interior of the connecting shell 210. Multiple connecting grooves 271 are provided on the moving rod 270. A connecting rod 272 is rotatably connected to the interior of the connecting groove 271, and one end of the connecting rod 272 is rotatably connected to the interior of the corresponding connecting groove 261. A circular rod 273 is fixedly connected to the moving rod 270, and the circular rod 273 is slidably connected to the corresponding circular hole 231. The outer diameter of the circular rod 273 is the same as the inner diameter of the circular hole 231.

[0039] In this embodiment, when the circular shell 100 rotates, the rotating circular shell 100 drives multiple fixed rods 220 and multiple connecting shells 210 to rotate, thereby causing multiple scraper bodies 230 to rotate. The rotating scraper bodies 230 facilitate the cleaning of the filter screen. When the scraper bodies 230 wear out after prolonged use, rotating the screw 250 causes the moving block 260 to move. The movement of the moving block 260 drives one end of multiple connecting rods 272 to move, thereby using the multiple connecting rods 272 to push the moving rod 270, the circular rod 273, and the multiple scraper bodies 230 to move. This facilitates fine-tuning of the position of the multiple scraper bodies 230, adjusting the distance between the multiple scraper bodies 230 and the filter screen, ensuring the scraper mechanism 200 effectively cleans the filter screen. To improve the cleaning effect of scraping foreign objects, if the scraper structure of the self-cleaning filter is damaged, the fixing frame 110, support frame 140 and multiple scraper mechanisms 200 are removed. By rotating the screw 250, the connecting rod 272 is deflected and moved. When the connecting rod 272 is in a horizontal state, the scraper body 230 and the round rod 273 are moved out of the interior of the connecting shell 210. By sliding multiple scraper bodies 230 upward, it is easy to remove the multiple scraper bodies 230 connected to the round rod 273. The installation of multiple scraper bodies 230 is simpler, more convenient and faster by using the sliding insertion of the round hole 231 and the round rod 273. After replacement, the screw 250 is reversed, causing the moving rod 270 to move into the interior of the connecting shell 210, thereby resetting the replaced scraper body 230.

[0040] like Figure 5 As shown, in this embodiment, a hexagonal block 251 is fixedly connected to the top of the screw 250, and the hexagonal block 251 is located inside the circular groove 211.

[0041] In practice, the hexagonal block 251 facilitates the rotation of the screw 250, and by connecting the sleeve to the hexagonal block 251 and using the sleeve in conjunction with the ratchet wrench, it is also convenient to rotate the hexagonal block 251 and the screw 250.

The outer side of the rotating shell 130 is connected to the fixed conveying pipe 131. The rinsing assembly includes a fixed shell 240 and an L-shaped shell 280. The fixed shell 240 is fixedly connected to the connecting shell 210 and to the corresponding fixed rod 220. The fixed shell 240 has a connecting hole at each of the multiple conveying holes 221. One end of the L-shaped shell 280 is connected and fixed to the fixed shell 240. The L-shaped shell 280 is fixedly connected to the connecting shell 210, and multiple nozzles 281 are connected and fixed on the L-shaped shell 280.

[0045] In specific implementation, by connecting the delivery pipe 131 to the water inlet of the external water pump and fixing the positions of the delivery pipe 131 and the rotating shell 130, the external water pump and delivery pipe 131 facilitate the delivery of water into the rotating shell 130, and multiple water inlets 101 facilitate the delivery of water into the round shell 100, and multiple water outlets 102 facilitate the delivery of water into the multiple delivery holes 221. The connecting holes on the fixed shell 240 allow water to flow into the fixed shell 240 and the L-shaped shell 280, and multiple nozzles 281 facilitate the spraying of water. The sprayed water can rinse the area scraped by the scraper body 230, improving the cleaning effect of the scraper mechanism 200. In use, the delivery component and the rinsing component can be selected for use as needed.

[0046] In specific implementation, by connecting 131 to the water inlet of an external water pump and fixing the positions of 131 and 130, the external water pump and 131 facilitate water delivery to the interior of 130, multiple 101 facilitate water delivery to the interior of 100, multiple 102 facilitate water delivery to the interior of multiple 221, and the connecting hole on 240 allows water to flow into the interior of 240 and 280, and multiple 281 facilitate water spraying. The sprayed water can rinse the area scraped by 230, improving the cleaning effect of 200. In use, the delivery component and the rinsing component can be selected for use as needed.
