Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a filtration device for wastewater treatment. Background Technology

[0002] Wastewater treatment is the process of removing or transforming pollutants in wastewater through physical, chemical, and biological methods to bring the water quality up to specific standards. Its core objective is to protect water resources and the ecological environment, and to achieve water recycling.

[0003] When treating wastewater, filtration equipment is usually used to filter the wastewater in order to remove impurities and particles.

[0004] Currently, most filtration equipment used for wastewater treatment lacks a cleaning mechanism. After the wastewater is filtered, it is not convenient to clean the filter screen inside the equipment. As a result, the filter screen is prone to clogging after a period of use, which reduces the subsequent filtration effect of the equipment. Utility Model Content

[0023] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-5 The present invention provides a technical solution: a filtration device for sewage treatment, comprising a filter frame 1, a filter chamber 24 and a purification chamber 25 respectively opened on the top of the filter frame 1, a filter screen frame 23 fixedly connected to the inner wall of the filter chamber 24, a hydraulic rod 2 fixedly connected to one side of the filter frame 1, a support rod 3 fixedly connected to one end of the hydraulic rod 2, a support frame 8 fixedly connected to one end of the support rod 3, a first motor 4 fixedly connected to the inner side wall of the support frame 8, a lead screw 6 fixedly connected to the output shaft of the first motor 4 through a coupling, and a movable block 5 movably connected to the outer wall of the lead screw 6.

[0025] A connecting rod 20 is fixedly connected to the bottom of the movable block 5. A brush plate 21 is fixedly connected to one end of the connecting rod 20. Brush bristles 22 are fixedly connected to the bottom of the brush plate 21. A sliding frame 7 is fixedly connected to the top of the support frame 8. A top frame 19 is fixedly connected to the top of the filter frame 1. A pump body 13 is fixedly connected to the top of the top frame 19. A water inlet pipe 9 is fixedly connected to the inlet of the pump body 13. A water outlet pipe 16 is fixedly connected to the outlet of the pump body 13. After the wastewater is filtered by the filtration equipment, the filter screen frame 23 can be brushed and cleaned to prevent the filtered impurities from sticking to the filter screen frame 23 and causing blockage. This ensures the cleanliness of the filter screen frame 23 and also ensures the filtration effect of the filtration equipment in subsequent use.

[0026] The shape and size of the combination of brush plate 21 and brush bristles 22 are matched with the shape and size of filter frame 23, and both brush plate 21 and brush bristles 22 are located above filter frame 23. By cleaning the filter frame 23, clogging of the filter frame 23 can be avoided, thus ensuring the filtration effect of the filter frame 23.

[0027] A fixed frame 15 is fixedly connected to the top of the top frame 19, and a second motor 10 is fixedly connected to the inner top wall of the fixed frame 15. The output shaft of the second motor 10 is fixedly connected to a rotating shaft 11 through a coupling. A movable shaft 14 is movably connected to the inner wall of the purification chamber 25, and stirring blades 18 are fixedly connected to the outer walls of the rotating shaft 11 and the movable shaft 14. This allows for stirring of the wastewater with the wastewater purification agent after filtration, so as to facilitate the purification treatment of the filtered wastewater and further improve the filtration effect.

[0028] A drive gear 12 is fixedly connected to the outer wall of the rotating shaft 11, and a driven gear 17 is meshed with the outer wall of the drive gear 12. The inner wall of the driven gear 17 is fixedly connected to the outer wall of the movable shaft 14. When the second motor 10 is working, the rotation of the rotating shaft 11 drives the movable shaft 14 to rotate, thereby reducing energy consumption.

[0029] One end of the water pumping pipe 9 extends into the interior of the filter chamber 24, and one end of the water supply pipe 16 extends into the interior of the purification chamber 25, so that the filtered wastewater can be introduced into the purification chamber 25 for purification treatment.

[0030] Both the bottom of the filter chamber 24 and the bottom of the purification chamber 25 are equipped with drain pipes, and the outer wall of the drain pipes is equipped with valves, which facilitates the discharge of wastewater from the cleaning filter screen frame 23 in the filter chamber 24 and the filtered and purified sewage in the purification chamber 25.

[0031] In use, when wastewater needs to be filtered, the wastewater is introduced into the filter chamber 24 inside the filter frame 1. After entering the filter chamber 24, the wastewater is filtered through the filter screen 23. After filtration, the pump body 13 can be turned on to allow the water pipe 9 to introduce the filtered wastewater from the filter chamber 24 into the purification chamber 25. An appropriate amount of reagent is added to the purification chamber 25. The second motor 10 is turned on to make the rotating shaft 11 drive the drive gear 12 to rotate. The drive gear 12 drives the driven gear 17 to rotate the movable shaft 14. When the rotating shaft 11 and the movable shaft 14 rotate, they respectively drive the stirring blades 18 to rotate, mixing the wastewater and the reagent. The filter screen 23 is designed to facilitate the purification of wastewater. After the wastewater is filtered and purified, when it is necessary to clean the filter screen 23, an appropriate amount of cleaning liquid or clean water can be added to the filter screen 23 according to actual needs. The hydraulic rod 2 is turned on to drive the support rod 3 to move the support frame 8 up and down horizontally. The support frame 8 drives the brush plate 21 to make the brush bristles 22 fit with the filter screen 23. The first motor 4 is turned on to drive the lead screw 6 to drive the movable block 5 to move the connecting rod 20 left and right horizontally. The connecting rod 20 drives the brush plate 21 to move the brush bristles 22 left and right horizontally. During the movement of the brush bristles 22, impurities on the filter screen 23 can be brushed and cleaned.
