Description

Technical Field

[0001] This utility model relates to the field of membrane integrated water treatment technology, and in particular to an impurity interception mechanism for a membrane integrated water reuse device. Background Technology

[0002] Membrane-integrated water reuse devices achieve wastewater purification and reuse through a combination of processes such as ultrafiltration membranes and reverse osmosis membranes. They are widely used in industrial wastewater treatment, municipal sewage treatment and other scenarios. Before membrane filtration, large-particle impurities such as suspended particles, fibers and colloids in the water need to be removed by an impurity interception mechanism to avoid impurities clogging the membrane pores and scratching the membrane surface, thus extending the service life of the membrane module.

[0003] Existing impurity interception mechanisms mostly use a single filter screen or grid structure. The filter screen is prone to clogging due to the accumulation of impurities, requiring regular manual cleaning. This not only increases operation and maintenance costs but also causes the device to shut down, reducing the continuity of water reuse. Furthermore, after impurities are intercepted, they tend to adhere to the surface of the filter screen, making it difficult to completely remove them during cleaning. Over time, this can easily lead to the growth of bacteria, contaminating the water body that is subsequently treated and affecting the quality of the effluent. Utility Model Content

[0004] In view of the above-mentioned problems in impurity treatment, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an impurity interception mechanism for a membrane integrated water recycling device, comprising a body, a mounting base fixedly connected to the bottom of the inner wall of the body, an inlet fixedly installed on the outer ring surface of the body communicating with the inner ring surface of the body, a filter cylinder threadedly connected to the inner ring surface of the mounting base, a mounting cover installed on the top of the filter cylinder, an annular through hole opened on the end face of the mounting cover, a plurality of evenly distributed movable grids slidably connected in the annular through hole, a mounting frame rotatably connected between every two adjacent movable grids, a scraper fixedly connected to the surface of the mounting frame, the scraper fitting against the outer ring surface of the filter cylinder, a push plate sleeved on the circumferential surface of the filter cylinder near the mounting base, the top of the push plate fixedly connected to the bottom of the mounting frame, a through hole opened on the top of the mounting base communicating with the bottom of the body, a drain pipe fixedly connected in the through hole, and pressure sensors fixedly installed on both the filter cylinder and the inner ring surface of the body.

[0011] The beneficial effects of this utility model are: Large particles are initially intercepted by a moving grille, followed by fine filtration through the filter cartridge. This system adapts to different water quality needs without requiring any component replacement, effectively avoiding the inconvenience of frequent disassembly and replacement required by traditional single-screen filters due to their fixed precision. A pressure sensor monitors water pressure changes in real time; when the pressure exceeds a preset threshold, it automatically initiates cleaning, rotating a scraper to remove impurities from the filter cartridge surface.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Example 1 Reference Figures 1-5 This is the first embodiment of the present invention, which provides an impurity interception mechanism for a membrane integrated water recycling device, including a body 1. A mounting base 2 is fixedly connected to the bottom of the inner wall of the body 1. An inlet 11 communicating with the inner ring surface of the body 1 is fixedly installed on the outer ring surface of the body 1. A filter cylinder 3 is threadedly connected to the inner ring surface of the mounting base 2. A mounting cover 5 is installed on the top of the filter cylinder 3. An annular through hole is opened on the end face of the mounting cover 5. Multiple evenly distributed movable grids 6 are slidably connected in the annular through hole. A mounting frame 7 is rotatably connected between every two adjacent movable grids 6. A scraper 8 is fixedly connected to the surface of the mounting frame 7. The scraper 8 is in contact with the outer ring surface of the filter cylinder 3. A push plate 9 is sleeved on the circumferential surface of the filter cylinder 3 near the mounting base 2. The top of the push plate 9 is fixedly connected to the bottom of the mounting frame 7. A through hole communicating with the bottom of the body 1 is opened on the top of the mounting base 2. A drain pipe 21 is fixedly connected in the through hole. Pressure sensors 10 are fixedly installed on both the filter cylinder 3 and the inner ring surface of the body 1.

[0020] A top cover 16 is fixedly connected to the top of the body 1. A drive motor is provided above the top cover 16. An active bevel gear 18 is fixedly connected to the output end of the drive motor. A driven bevel gear 17 meshes with the circumferential surface of the active bevel gear 18. A connecting column 15 is fixedly connected to the bottom end of the driven bevel gear 17.

[0021] The bottom end of the connecting column 15 extends through the top cover 16 to the top end of the mounting cover 5. The top end of the mounting bracket 7 is fixedly connected to the fixing column 12. The circumferential surface of the fixing column 12 is fitted with a rotating plate 13. One end of the rotating plate 13 is fixedly connected to the circumferential surface of the connecting column 15.

[0022] During use, the wastewater to be treated enters the body 1 through the inlet 11 and first flows through the movable grille 6 on the end face of the mounting cover 5. The movable grille 6 initially intercepts larger suspended impurities such as fibers and particulate matter in the wastewater by setting the spacing. The wastewater after initial filtration flows to the filter cartridge 3, and further filters fine impurities through the filter membrane structure of the filter cartridge 3. The purified water is discharged from the outlet 19 at the bottom of the body 1 and enters the subsequent membrane integrated treatment unit.

[0023] Pressure sensors 10 on the main body 1 and filter cartridge 3 monitor the water pressure difference between them in real time. When the residual impurities on the surface of filter cartridge 3 gradually increase, the water flow resistance increases, and the water pressure difference exceeds the preset threshold. Pressure sensor 10 transmits a signal to the controller, which then starts the drive motor above the top cover 16. The output of the drive motor drives the active bevel gear 18 to rotate. The active bevel gear 18 meshes with and drives the driven bevel gear 17 to rotate. The driven bevel gear 17 drives the rotating plate 13 to rotate synchronously through the connecting column 15. When the rotating plate 13 rotates, it pushes... The fixed column 12 causes the mounting frame 7 to rotate around the filter cylinder 3. The scraper 8 on the surface of the mounting frame 7 slides close to the outer ring surface of the filter cylinder 3 to scrape off the attached impurities. At the same time, the mounting frame 7 drives the push plate 9 to rotate at the bottom of the filter cylinder 3, pushing the scraped impurities to the through hole at the top of the mounting base 2. At this time, the valve of the drain pipe 21 opens, and the impurities are discharged from the machine body 1 through the drain pipe 21. After cleaning is completed, the pressure sensor 10 detects that the water pressure difference has returned to normal, the controller closes the drive motor and the drain pipe 21 valve, and the device returns to normal filtration state.

[0024] Example 2 Reference Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a magnetic block 14 is fixedly connected to one end of the mounting cover 5 near the filter cylinder 3, a magnetic sheet that is in contact with and attracts the magnetic block 14 is fixedly connected to the top of the filter cylinder 3, and a sealing gasket 4 is fixedly connected to the top of the mounting base 2, with the top of the sealing gasket 4 in contact with the bottom of the filter cylinder 3.

[0025] The bottom of the body 1 is provided with a water outlet 19. A valve is fixedly installed on the inner ring surface of the water outlet 19. The drain pipe 21 is equipped with the same valve as the water outlet 19 on the inner ring surface near the top of the mounting base 2.

[0026] Multiple evenly distributed sliders 20 are fixedly connected to the outer ring surface of the mounting cover 5. Multiple sliding grooves corresponding to the sliders 20 are opened at the top of the body 1, and the sliding grooves are slidably connected to the sliders 20.

[0027] During use, when the filter cartridge 3 needs to be replaced, use a tool to loosen the connection structure between the top cover 16 and the body 1, and remove the top cover 16 upward from the body 1. The top cover 16 drives the drive motor, the active bevel gear 18, the driven bevel gear 17 and the connecting column 15 above to separate synchronously. The rotating plate 13 is separated from the fixed column 12 along with the connecting column 15, releasing the constraint on the mounting bracket 7.

[0028] Pull the mounting cover 5 upwards. The slider 20 on the outer ring of the mounting cover 5 slides along the groove at the top of the machine body 1, causing the magnetic block 14 at the bottom of the mounting cover 5 to disengage from the magnetic attraction at the top of the filter cartridge 3. At this time, the filter cartridge 3 is only fixed by the threaded connection between its bottom and the mounting base 2. Rotate the filter cartridge 3 to separate it from the mounting base 2, and the filter cartridge 3 can be removed from the machine body 1. When replacing the new filter cartridge 3, reverse the above steps and thread the new filter cartridge 3 to the mounting base 2. The sealing gasket 4 at the top of the mounting base 2 ensures that the connection is sealed. Lower the mounting cover 5 so that the magnetic block 14 is attracted and fixed to the magnetic plate at the top of the filter cartridge 3. Finally, reset the top cover 16 and the transmission assembly to complete the replacement.

[0029] The remaining structure is the same as that in Example 1.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
