Specific embodiments

[0028] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] In order to facilitate the addition of a multi-layer filter membrane structure, control and adjust the filtering quality and effect of the filtering device, thereby improving the use effect, as Figures 1-5 shown, a filtering device with a multi-layer membrane filtering structure according to the present utility model includes a housing 1, a positioning component 3 and a filter membrane component 4. A support rod 2 is arranged inside the housing 1. A positioning component 3 is sleeved outside the support rod 2, and a filter membrane component 4 is fixedly sleeved outside the positioning component 3;

[0030] The positioning component 3 includes a sliding sleeve 301. Levers 302 are arranged on both sides inside the sliding sleeve 301. Both sides of the top of the lever 302 are connected to a rotating shaft 303 by welding, and the lever 302 is rotatably connected to the sliding sleeve 301 through the rotating shaft 303. One side of the bottom of the lever 302 is fixedly connected to an insertion rod 304 for positioning by screws;

[0031] The filter membrane component 4 includes a mounting frame 401, and the sliding sleeve 301 is connected to the mounting frame 401 by bolts. A filter membrane 402 for filtering is fixedly arranged inside the mounting frame 401.

[0032] The filter membrane 402 includes a nylon filter membrane, a polypropylene filter membrane, and a glass fiber filter membrane.

[0033] During use, through the sliding sleeve 301, the lever 302, the rotating shaft 303, the inserting rod 304, the mounting frame 401 and the filter membrane 402, a multi-layer filter membrane structure can be realized in a way of socketing and sliding, increasing or decreasing and adjusting, so as to adapt to different sewage water qualities and usage requirements for filtration, thereby improving the flexibility of use and at the same time being beneficial to reducing the usage cost.

[0034] In order to improve the functionality of the equipment during use, by way of example, as Figure 3 , Figure 5 shown, the present utility model further includes that an arc-shaped piece 403 is rotatably connected to the periphery of the mounting frame 401 through a rotating shaft, a scraping piece 404 is connected to the outside of one end of the arc-shaped piece 403 by welding, a spring 405 is fixedly installed inside the mounting frame 401 and on the inner side of the arc-shaped piece 403 through a clamping groove, and sealing rings 406 are installed on the periphery of the mounting frame 401 at the top and bottom of the arc-shaped piece 403 through clamping grooves.

[0035] During use, through the arc-shaped piece 403, the scraping piece 404 and the spring 405, it is possible to use elastic force to push, and while disassembling and replacing the filter membrane assembly 4, assist in cleaning the inner wall of the housing 1, thereby improving the functionality of the equipment during use.

[0036] By way of example, as Figure 4 shown, the present utility model further includes that a coil spring 305 is sleeved on the periphery of the rotating shaft 303, one end of the coil spring 305 is connected to the rotating shaft 303 by welding, the other end of the coil spring 305 is connected to the sliding sleeve 301 through a clamping groove, and a pull rod 306 is connected to the other side of the bottom of the lever 302 by welding.

[0037] During use, the elastic deformation of the coil spring 305 drives the rotating shaft 303 to rotate, so that the inserting rod 304 can be driven to quickly perform a limiting and fixing action, and the pull rod 306 facilitates driving the lever 302 to slide outward for unlocking.

[0038] By way of example, as Figure 6 shown, the present utility model further includes that jacks 201 corresponding to the inserting rod 304 are formed on the surface of the support rod 2, threaded sections 202 are provided at both ends of the support rod 2, and flow equalizing plates 5 are threadedly connected to both ends of the support rod 2 through the threaded sections.

[0039] During use, the jacks 201 facilitate the insertion of the inserting rod 304 for quick limiting and fixing, and the threaded sections 202 facilitate the threaded connection of the flow equalizing plates 5 to enable sewage to enter and exit the equipment evenly.

[0040] By way of example, as Figure 2 shown, the present utility model further includes that a top cover 101 is threadedly connected to the top of the housing 1, the top cover 101 includes a water inlet 102, and a water outlet 103 is formed at the bottom of the housing 1.

[0041] During use, through the top cover 101, the water inlet 102 and the water outlet 103, it is convenient for sewage to enter and exit the device for filtration treatment.

[0042] When the utility model is in use, first, the operator slides the sliding sleeve 301 up and down around the outer periphery of the support rod 2 according to the actual wastewater quality and usage requirements to adjust its usage height and spacing. Then, the elastic deformation of the coil spring 305 drives the rotating shaft 303 and the lever 302 to rotate inward, so that the insertion rod 304 is inserted into the corresponding jack 201 of the support rod 2 to complete the limit fixing installation process. By adjusting the number of the filter membrane assemblies 4, not only can the usage effect of the device be improved to meet different usage requirements, but also it is beneficial to reduce the usage cost and resource waste. The use of the multi-layer filter membrane 402 structure can also improve the filtration effect and quality of sewage;

[0043] During the process of disassembling the filter membrane assembly 4 for replacement, by pulling up the support rod 2, the positioning assembly 3 and the filter membrane assembly 4 are taken out of the housing 1 together. At the same time, the support rod 2 can also be rotated, and the elastic force of the spring 405 is used to push one end of the arc-shaped piece 403 to rotate outward, so that the scraping piece 404 is in contact with the inner wall surface of the housing 1, playing an auxiliary cleaning function, and the dirt attached to the inner wall of the housing 1 can be taken out, thereby improving the convenience and functionality of the device, and having a relatively high practical value.
