Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] Example Please see Figures 1 to 4 This embodiment provides a technical solution: a wastewater detection solid-liquid separation device, comprising... The back plate 100, the water receiving tank 200 fixed at the bottom of the back plate 100, and the water holding frame 300 set on one side of the back plate 100 and located at the top of the water receiving tank 200 are connected at the top and bottom. When performing solid-liquid separation, wastewater can be put into the inside of the water holding frame 300 first, and the wastewater will seep into the inside of the water holding frame 300. The filter assembly 400 includes a filter frame 401 fixedly connected to the bottom of the water-holding frame 300 and connected to the back plate 100, three pull-out grooves 402 formed on the surface of the filter frame 401, and a filter screen plate 403 slidably installed inside the pull-out grooves 402. The upper and lower ends of the filter frame 401 are connected. The bottom opening of the water-holding frame 300 and the top opening of the filter frame 401 are adapted to each other. The filter screen plate 403 completely covers the inside of the filter frame 401. Wastewater flows from the water-holding frame 300 into the interior of the filter assembly 400. Through the three layers of filter screen plates 403, the wastewater can be filtered in stages, thereby improving the filtration effect. Moreover, the filter screen plate 403 can be completely removed from the pull-out grooves 402 by pulling it out, which is convenient for cleaning. A connecting plate 500 is fixedly connected between the filter frame 401 and the back plate 100, thus completing the fixed connection between the filter frame 401 and the back plate 100.

[0016] In this embodiment, preferably, the filter assembly 400 further includes a sealing sheet 404. The sealing sheet 404 is fixed to the front end of the filter screen plate 403 and its size is larger than the pull-out groove 402. When the filter screen plate 403 is inserted into the pull-out groove 402, the sealing sheet 404 can block the outside of the pull-out groove 402 and play a sealing role.

[0017] In this embodiment, preferably, the filter assembly 400 further includes a pull handle 405, which is fixed to the surface of the sealing sheet 404 to facilitate the pulling of the filter screen plate 403.

[0018] In this embodiment, preferably, the filter assembly 400 further includes rubber damping pads. The rubber damping pads are disposed on the inner walls of both sides of the pull-out groove 402 and are pressed against both sides of the filter screen plate 403 to increase friction. Except for manual pulling, the filter screen plate 403 is not easily moved.

[0019] In this embodiment, preferably, a top plate 600 is fixed to the top of the back plate 100, and a hydraulic rod 700 is provided on the bottom surface of the top plate 600. A top cover 800 is fixedly connected to the bottom end of the hydraulic rod 700. The inner wall of the top cover 800 is adapted to the outer surface of the water-holding frame 300. By activating the hydraulic rod 700, the top cover 800 can be pushed to cover the top of the water-holding frame 300. An air pump assembly 900 is provided between the top plate 600 and the top cover 800, including an air pump 901 provided on the surface of the top plate 600 and an air pipe 902 connected between the air pump 901 and the top cover 800. The inner sides of 902 and the top cover 800 are connected. During filtration, the wastewater can be allowed to settle and filter naturally in the water holding frame 300 and the filter assembly 400. If blockage occurs or there are too many impurities and a large amount of wastewater is absorbed, the top cover 800 can be placed on top of the water holding frame 300, and then the air pump 901 can be started to pressurize the inside of the water holding frame 300 through the air pipe 902. The air pressure can accelerate the infiltration of wastewater and squeeze out the wastewater absorbed in the impurities to a certain extent. The air pipe 902 is made of a flexible material to adapt to the lifting and moving of the top cover 800.

[0020] In this embodiment, preferably, a rubber sealing gasket 1000 is provided on the inner upper wall of the top cover 800. The rubber sealing gasket 1000 is adapted to the top of the water-holding frame 300. After the top cover 800 is placed over the top of the water-holding frame 300, the rubber sealing gasket 1000 can be squeezed and fitted to the top of the water-holding frame 300 to ensure a good sealing effect at the top of the water-holding frame 300.

[0021] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
