DETAILED DESCRIPTION

[0018] In order for those skilled in the art to better understand the utility model, the technical solutions of the utility model are further described below in combination with the drawings and embodiments.

[0019] Embodiment one:

[0020] As shown in Figure 1 and Figure 2 , wherein Figure 1 is the overall structure schematic view of the filter device for sewage, Figure 2 is the structure schematic view of the positioning seat 104, the utility model provides a filter device for sewage: including filter box 101, controller 102, water guide pipe 103 and filter assembly, the filter assembly includes positioning seat 104, first fixing frame 105, second fixing frame 106, first filter screen 107, second filter screen 108 and warning component, the warning component includes liquid level sensor 109 and alarm part, the alarm part includes bracket 110, warning light 111 and buzzer 112. Through the foregoing scheme, the problem that the existing filter device needs to stop sewage into the sewage pool when cleaning the filter screen can be solved, and then the problem that the filter screen cannot be cleaned in real time, resulting in low filtering efficiency. It can be understood that the foregoing scheme can improve the filtering efficiency.

[0021] In the embodiment, the controller 102 is installed on the front side of the filter box 101, and the water guide pipes 103 are installed on the left and right sides respectively, the shell of the controller 102 is fixed by bolts, and the connecting flanges of the water guide pipes 103 are fixed on the water inlet and water outlet of the filter box 101 by bolts and are connected with the corresponding water conveying pipes outside respectively.

[0022] The positioning seat 104 is detachably connected with the filter box 101 and symmetrically arranged in the filter box 101, the first fixing frame 105 is detachably connected with the left positioning seat 104, the number is two, the second fixing frame 106 is detachably connected with the right positioning seat 104, the number is two, the first filter screen 107 is welded in the square water cavity of the first fixing frame 105, the second filter screen 108 is welded in the square water cavity of the second fixing frame 106, and the filter hole diameter is smaller than that of the first filter screen 107, and the warning member is arranged on one side of the filter box 101 and electrically connected with the controller 102. The positioning seat 104 is an open upward U-shaped structure, and cooperating sliding grooves are arranged on the inner side wall and the bottom of the filter box 101, so that the positioning seat 104 is slidably installed, finally, the positioning seat 104 is fixed by bolts, the positioning seat 104 is symmetrically arranged and vertically arranged with two sliding grooves, so that the first fixing frame 105 and the second fixing frame 106 are slidably installed, the first fixing frame 105 and the second fixing frame 106 are consistent in size, and are fixed by bolts after sliding installation, which is beneficial to the disassembly and cleaning of the first filter screen 107 and the second filter screen 108, and the first filter screen 107 and the second filter screen 108 are welded in the square water cavity respectively for filtering, the warning member is used for warning when the water level rises due to the blockage of the filter screen, so that the first filter screen 107 and the second filter screen 108 can be cleaned in time, and the positioning seat 104 is provided with a corrosion-resistant coating on the surface for prolonging the service life.

[0023] Secondly, a plurality of liquid level sensors 109 are arranged on the top side of the filter box 101; the alarm component is electrically connected with the controller 102 and arranged on the left side wall of the filter box 101. The liquid level sensor 109 is used for water level monitoring, when the filter holes of the first filter screen 107 and the second filter screen 108 are blocked by impurities, the water flow is blocked, at this time, the water level in the filter box 101 will rise, so that a plurality of liquid level sensors 109 can be arranged for water level monitoring, when the liquid level sensor 109 detects the water level, an electrical signal is fed back to the controller 102, the controller 102 controls the alarm component to act and warn, then the first filter screen 107 and the second filter screen 108 need to be cleaned in time, so as to avoid water overflow from the filter box 101.

[0024] Then, the bracket 110 is fixed to the left side wall of the filter box 101; the warning light 111 is electrically connected to the controller 102 and fixed to the top of the bracket 110. The bracket 110 is L-shaped and is fixed with bolts. The base of the warning light 111 is fixed with bolts from bottom to top and is electrically connected to the controller 102 via a power cord. When working, it flashes red.

[0025] Finally, the buzzer 112 is fixed to the bracket 110 and electrically connected to the controller 102. The buzzer 112 is fixed with bolts and electrically connected to the controller 102 via a power cord, and can emit an alarm sound to remind users when in operation.

[0026] When using this utility model to solve the problem of low filtration efficiency caused by the need to stop sewage from entering the sewage tank when cleaning the filter screen in existing filtration devices, which leads to the inability to clean the filter screen in real time, sewage is introduced into the filter box 101 through the water guide pipe 103 on the left side during sewage filtration. Then, the sewage is filtered in stages by the first filter screen 107 and the second filter screen 108 and discharged through the water guide pipe 103 on the right side. When cleaning the first filter screen 107 and the second filter screen 108, they are respectively set into two sets with the cooperation of the first fixing frame 105 and the second fixing frame 106 of the same size. This design allows for direct disassembly of one set of the first filter screen 107 and one set of the second filter screen 108 during cleaning. Meanwhile, the remaining sets of the first and second filter screens 107 and 108 will work together to filter, ensuring simultaneous water injection and cleaning. After cleaning, the disassembled and cleaned set of the first and second filter screens 107 and 108 are reinstalled for filtration. Then, the other set of filter screens can be directly disassembled and cleaned. This eliminates the need to stop water injection during cleaning, thus solving the problem of existing filtration devices requiring the cessation of wastewater entry into the wastewater tank for filter screen cleaning, which leads to low filtration efficiency due to the inability to clean the filter screens in real time.

[0027] Example 2:

[0028] like Figure 3 As shown, where Figure 3 This is a schematic diagram of the overall structure of a wastewater filtration device. Based on the first embodiment, this utility model provides a wastewater filtration device, which also includes auxiliary components, including a support frame 201 and a third filter screen 202.

[0029] The support frame 201 is detachably connected with the filter box 101 and located between the positioning seats 104; the third filter screen 202 is welded in the mouth-shaped water passage of the support frame 201, and the filter hole diameter of the third filter screen 202 is smaller than that of the first filter screen 107 and larger than that of the second filter screen 108. The support frame 201 is T-shaped and fixed by bolts, and the bottom surface and the two side surfaces of the support frame 201 are respectively attached to the filter box 101 after installation; the third filter screen 202 is welded in the mouth-shaped water passage of the support frame 201, and the third filter screen 202 can cooperate with the first filter screen 107 and the second filter screen 108 to form a three-level filter structure after installation.

[0030] In the embodiment, the three-level filter structure can be formed by arranging the support frame 201 and the third filter screen 202, the filtering effect is further improved, the fixing bolts of the support frame 201 are removed, and the third filter screen 202 can be directly taken out for cleaning; since the third filter screen 202 is located between the first filter screen 107 and the second filter screen 108 after installation, the two-level filter structure still exists after the third filter screen 202 is removed, and sewage can be filtered and treated.

[0031] The above embodiment only exemplarily illustrates the principle and effect of the utility model, and is not used for limiting the utility model. Any person skilled in the art can modify or change the above embodiment without departing from the spirit and category of the utility model.
