Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically to the impurity cleaning structure of a multi-stage filtration device. Background Technology

[0002] Bottled water, as a convenient drinking water solution, is widely used in homes, offices, and public places. The production process of bottled water involves filtration. Multi-stage filtration technology removes impurities, microorganisms, and harmful substances from the water through multiple filtration layers (such as activated carbon, ultrafiltration membranes, and reverse osmosis membranes), significantly improving water quality safety and stability.

[0003] Utility model patent with authorization announcement number CN202322732315.2 discloses a purification device for drinking water treatment. The purification device includes a drinking water filter body, a filter screen, and a drinking water purification device body. A water pump is fixedly installed on one side of the top of the drinking water purification device body. A water suction pipe is connected to the bottom of the drinking water filter body through one side of the water pump. A purification agent inlet is fixedly installed through the other side of the top of the drinking water purification device body. An oil adsorption screen is slidably installed inside the drinking water filter body. Fixing plates are fixedly installed on both sides of the inner wall of the drinking water filter body. A through groove is opened inside the fixing plate. A sliding rod fixed to the oil adsorption screen is slidably installed inside the through groove. The system consists of a main body for drinking water filtration, a filter screen, a water pump, a suction pipe, and a purification agent inlet. Water to be purified is filtered through the filter screen, trapping sediment at the top. The water pump then draws the water into the main body of the drinking water purification system through the suction pipe. Finally, the purification agent is added into the main body of the drinking water purification system through the purification agent inlet to purify the drinking water, thus preventing sediment from affecting the water quality during the purification process.

[0004] Although the purification equipment for drinking water treatment avoids the impact of sediment on water quality, the device still has the following problems in actual use: While the design achieves efficient filtration of the water source through multiple filters, a large amount of impurities gradually accumulates on the filter surface as the filtration process continues. However, the current device does not integrate an automatic cleaning function, requiring users to manually clean the impurities on the filter screens periodically. This design not only increases the user's operational burden but may also lead to a decrease in equipment operating efficiency and even affect the filtration effect. Therefore, we propose a multi-filtration device impurity cleaning structure. Utility Model Content

[0005] The purpose of this invention is to provide an impurity cleaning structure for a multi-stage filtration device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The impurity cleaning structure of the multi-stage filtration device includes a base, two support plates fixed on the top of the base, a motor installed at the front end of the support plate on the front side, the output shaft of the motor coaxially connected to a first sprocket, a second sprocket above the first sprocket, and a chain between the first sprocket and the second sprocket.

A main pipe is installed at the front end of the connecting pipe. Multiple horizontal pipes are fixed on the outer wall of the main pipe. The horizontal pipes pass through to the bottom of the filter screen inside the tank. Multiple ring pipes are fixed on the outer wall of the horizontal pipes. Multiple spray holes for backwashing the filter screen are opened at the top of the ring pipes.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The design incorporates a motor, tank, and backwashing mechanism: during filter cleaning, the tank rotates 180°, causing the drain pipe to rotate downwards. Cleaning water enters through a bend in the pipe and flows into multiple horizontal pipes, exiting through multiple spray nozzles. The sprayed water is directly applied to the filter screen, causing impurities adhering to it to detach and be discharged to the outside through the drain pipe. This design facilitates backwashing of multiple filter screens, making operation convenient and quick, improving filter cleaning efficiency, and ensuring the filter screen's filtration efficiency for bottled water.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0029] Example 1

[0030] Please see Figures 1-4 As shown, the impurity cleaning structure of the multi-stage filtration device includes a base 1. Two support plates 10 are fixed to the top of the base 1. A motor 12 is installed at the front end of the front support plate 10. The output shaft of the motor 12 is coaxially keyed to a first sprocket 13. A second sprocket 15 is located above the first sprocket 13. A chain 14 is provided between the first sprocket 13 and the second sprocket 15. A hollow tank 2 is located between the two support plates 10. A connecting shaft 27 is fixed to the front side of the outer wall of the tank 2. The connecting shaft 27 passes through the front support plate 10 and is coaxially keyed to the second sprocket 15. Multiple filter screens 20 are installed inside the tank 2. A backwash mechanism 3 is provided on the rear side. The backwash mechanism 3 includes a bent pipe 30. A connecting pipe 32 is provided on the front side of the bent pipe 30. A rotary joint 31 is provided between the connecting pipe 32 and the bent pipe 30. The connecting pipe 32 is rotatably connected to the bent pipe 30 through the rotary joint 31. The connecting pipe 32 passes through the support plate 10 on the rear side and is rotatably connected to the support plate 10. A main pipe 33 is installed at the front end of the connecting pipe 32. Multiple horizontal pipes 34 are fixed on the outer wall of the main pipe 33. The horizontal pipes 34 pass through to the bottom of the filter screen 20 in the tank body 2. Multiple ring pipes 35 are fixed on the outer wall of the horizontal pipes 34. Multiple spray holes 350 for backwashing the filter screen 20 are opened at the top of the ring pipes 35.

[0031] In this embodiment, a drain outlet 25 is installed at the bottom of the tank 2, and a drain pipe 26 is fixedly installed at the front end of the drain outlet 25 via a flange. The drain outlet 25 and the drain pipe 26 facilitate the discharge of filtered water, and the flange fixing method not only ensures a secure connection but also facilitates the disassembly and assembly of the drain pipe 26 and the drain outlet 25, thereby making it convenient to turn the tank 2 around when cleaning the filter screen 20 later.

[0032] In this embodiment, a water inlet 21 is installed on the top of the tank 2, and a three-way valve 22 is installed on the top of the water inlet 21. A water inlet pipe 23 and a sewage discharge pipe 24 are respectively installed at the two openings of the three-way valve 22. The design of the three-way valve 22 allows for flexible switching between water inlet and sewage discharge, improving the ease of operation and functionality of the equipment. The separate design of the water inlet 21 and the sewage discharge pipe 24 avoids cross-contamination and ensures water quality safety.

[0033] In this embodiment, two connecting blocks 28 are tightly welded to the rear side of the outer wall of the tank 2. The main pipe 33 passes through the connecting blocks 28 and is fixedly connected to the connecting blocks 28 by bolts. The bolted connection blocks 28 enhance the stability of the main pipe 33, ensure the smooth operation of the backflushing mechanism 3, and extend the service life of the equipment. At the same time, the design of the connecting blocks 28 facilitates disassembly and maintenance, improving the ease of equipment maintenance.

[0034] In this embodiment, a mounting plate 11 is fixed to the front end face of the support plate 10 located on the front side, and the motor 12 is fixedly connected to the mounting plate 11 by bolts. The mounting plate 11 provides stable support for the motor 12, ensuring the installation stability and reliability of the motor 12.

[0035] In this embodiment, the overall shape of the ring tube 35 is ring-shaped, and multiple ring tubes 35 are arranged concentrically. The concentric ring design optimizes the backwashing effect, ensures thorough cleaning of the filter screen 20, and improves filtration efficiency.

[0036] In this embodiment, the cross-sectional shape of the nozzle 350 is circular, and multiple nozzles 350 are distributed in a ring with equal spacing. The design of the nozzles 350 can evenly distribute the high-pressure water flow and avoid the problem of incomplete cleaning in some areas.

[0037] In this embodiment, a sealing ring is provided at the point where the horizontal pipe 34 enters the tank body 2. The sealing ring is made of rubber. The rubber sealing ring effectively prevents leakage, enhances the sealing performance and durability of the equipment, and is suitable for high-pressure environments. At the same time, the design of the sealing ring facilitates replacement and maintenance, reducing equipment operating costs.

[0038] It is worth noting that the motor 12 involved in this embodiment is a conventional technology and will not be described in detail here.

[0039] When cleaning the filter screen 20, the user first releases the fixing between the drain pipe 26 and the drain outlet 25, and simultaneously releases the fixing between the inlet pipe 23 and the water supply pipe. Then, the user rotates the valve stem of the three-way valve 22, connecting the drain pipe 24 to the inlet 21. Next, the user connects the power to the motor 12, which begins to operate. The output shaft of the motor 12 rotates, driving the first sprocket 13 to rotate. Under the action of the chain 14, the second sprocket 15 rotates, driving the connecting shaft 27 to rotate. The connecting shaft 27 drives the tank 2 to rotate, and the tank 2 drives the main pipe 33 and the connecting pipe 32 to rotate. When the tank 2 rotates 180°, the user stops the motor 12. Next, the cleaning water enters the connecting pipe 32 and the main pipe 33 through the bend pipe 30. At the same time, the cleaning water enters multiple horizontal pipes 34 and multiple ring pipes 35. Finally, the water is sprayed onto the filter screen 20 through multiple spray holes 350. Under the flushing of the water, the impurities on the filter screen 20 are removed and finally discharged to the outside through the inlet 21 and the drain pipe 24.
