Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment filter structure. Background Technology

[0002] Filtration is a crucial step in wastewater treatment. Typically, wastewater is filtered using filter cartridges, which adsorb solid impurities from the water to remove some of them. However, for small-scale wastewater treatment equipment, the filter cartridges need to be removed and cleaned after filtration, which is quite inconvenient. Utility Model Content

[0003] The purpose of this application is to provide a wastewater treatment filter structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this application provides the following technical solution: a wastewater treatment filter structure, comprising a housing, a first rubber plug fixedly installed at the bottom of the inner cavity of the housing, a top cover installed at the top of the housing, a buffer mechanism connected to the bottom of the top cover, a pressure plate connected to the bottom of the buffer mechanism, a second rubber plug fixedly installed at the bottom of the pressure plate, a cylindrical filter element coaxial with the housing inside the housing, the upper and lower ends of the cylindrical filter element being inserted into the second rubber plug and the first rubber plug respectively, and a water inlet fixedly installed on the top cover, one end of the water inlet extending to the top of the top cover. The bottom end of the inlet leads into the interior of the cylindrical filter element. A motor is fixedly mounted on the bottom end of the outer shell. The output end of the motor drives and connects to a first gear. A hollow stirring tube is rotatably mounted on the bottom end of the outer shell. The hollow stirring tube leads into the interior of the cylindrical filter element. A second gear that meshes with the first gear is fixedly mounted on the outer side of the bottom end of the hollow stirring tube. A through hollow branch pipe is connected to the outer wall of the hollow stirring tube. Brush bristles are fixedly mounted on the outer wall of the end of the hollow branch pipe. A drain hole is provided at the top of the hollow stirring tube near the first rubber stopper.

[0005] Preferably, the bottom end of the hollow stirring tube is rotatable and connected to a three-way pipe. One branch of the three-way pipe is a water injection pipe and a first valve is fixedly installed on this branch. A second valve is fixedly installed on the other branch of the three-way pipe.

[0006] Preferably, the bottom side of the outer casing is provided with a drain outlet communicating with its interior.

[0007] Preferably, the buffer mechanism includes a sleeve and a spring. The top end of the sleeve is fixedly connected to the bottom end of the top cover, the spring is sleeved on the sleeve, and the bottom end of the sleeve is slidably connected to the inner cavity of the pressure plate.

[0008] Preferably, the top cover and the outer shell are detachably connected by bolts.

[0009] In summary, the technical effects and advantages of this utility model are as follows:

[0010] In this invention, a motor drives a first gear to rotate, which in turn drives a second gear to rotate a hollow stirring tube. This causes the bristles to clean the inner wall of the cylindrical filter element. At the same time, water is injected into the hollow stirring tube through a water injection pipe. The water is sprayed from the end of the hollow branch pipe onto the inner wall of the cylindrical filter element for further cleaning. The wastewater from the cleaning process can enter the hollow stirring tube through the drain hole and be discharged through another branch of the three-way pipe. This makes maintenance very convenient. Attached Figure Description

[0019] Example: Reference Figure 1-2The wastewater treatment filter structure shown includes a housing 1. A first rubber plug 2 is fixedly installed at the bottom of the inner cavity of the housing 1. A top cover 4 is installed at the top of the housing 1. A buffer mechanism is connected to the bottom of the top cover 4. A pressure plate 5 is connected to the bottom of the buffer mechanism. A second rubber plug 6 is fixedly installed at the bottom of the pressure plate 5. A cylindrical filter element 3, coaxial with the housing 1, is provided inside the housing 1. The upper and lower ends of the cylindrical filter element 3 are respectively inserted into the second rubber plug 6 and the first rubber plug 2. An inlet 7 is fixedly installed on the top cover 4. One end of the inlet 7 extends above the top cover 4, and the bottom end of the inlet 7 leads into the interior of the cylindrical filter element 3. A motor 9 is fixedly mounted at the bottom of the housing 1. The output end of the motor 9 drives a first gear 10. A hollow stirring tube 11 is rotatably installed at the bottom of the housing 1. The hollow stirring tube 11 leads into the interior of the cylindrical filter element 3. A second gear 12, which meshes with the first gear 10, is fixedly installed on the outer side of the bottom end of the hollow stirring tube 11. A through hollow branch pipe 18 is connected to the outer wall of the hollow stirring tube 11. Brush bristles 19 are fixedly installed on the outer wall of the end of the hollow branch pipe 18. A drain hole 20 is provided at the top of the hollow stirring tube 11 near the first rubber stopper 2. The bottom end of the hollow stirring tube 11 rotates and is connected to a three-way pipe. One branch of the three-way pipe is a water injection pipe 8, and a first valve 14 is fixedly installed on this branch. A second valve 15 is fixedly installed on the other branch of the three-way pipe. The first gear is driven by a motor to rotate, which in turn drives the second gear to rotate the hollow stirring tube, so that the brush bristles clean the inner wall of the cylindrical filter element. At the same time, water is injected into the hollow stirring tube through the water injection pipe. The water sprays out from the end of the hollow branch pipe to the inner wall of the cylindrical filter element for brushing. The wastewater from brushing can enter the hollow stirring tube from the drain hole and be discharged through the other branch of the three-way pipe. This makes maintenance very convenient.
