Description

Technical Field

[0001] This utility model relates to the technical field of anaerobic tank sealing devices, and in particular to a sealing device for a water treatment filter. Background Technology

[0002] An anaerobic filtration tank is a device used for wastewater treatment. Its working principle is based on the metabolic process of anaerobic microorganisms, which mainly includes four steps: filtration, hydrolysis, absorption and denitrification.

[0003] Patent document CN222277482U discloses a sealing device for an anaerobic digester, including an anaerobic digester body and a sealing cover installed on top of the anaerobic digester body. A sealing assembly connects the anaerobic digester body and the sealing cover, belonging to the field of anaerobic digester technology. This invention, by setting a sealing assembly, achieves triple sealing between the anaerobic digester body and the sealing cover after the sealing cover is placed on top of the anaerobic digester body. This is achieved through the sealing fit between the abutment ring and the sealing plate, and the sealing fit between the inner and outer walls of the insert ring and the inside of the annular sealing ring. This effectively prevents the leakage of malodorous gases from the anaerobic digester body, reducing the risk of environmental pollution and pollutant diffusion. The reinforcing assembly allows the sealing cover to automatically slide towards the anaerobic digester body. Inserting the insert ring into the annular sealing ring improves the sealing performance between the insert ring and the annular sealing ring, as well as between the abutment ring and the sealing plate. This is more convenient and efficient than traditional multi-bolt fixing, and extends the service life of the sealing components.

[0004] In actual use, the above solution can only open and close the anaerobic tank and the sealing cover at a certain distance, but cannot completely separate the sealing cover from the anaerobic tank. As a result, when it is necessary to clean the inside of the anaerobic tank, it is still necessary to manually lift the sealing cover until the anaerobic tank is completely opened, which brings inconvenience to the opening of the anaerobic tank. Utility Model Content

[0005] This utility model discloses a sealing device for a water treatment filter, which aims to solve the technical problem that the existing sealing devices for anaerobic ponds are inconvenient to open and close.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sealing device for a water treatment filter includes a tank body, an installation opening on the left side of the tank body, a sealing cover plate inside the installation opening, an opening and closing mechanism between the tank body and the sealing cover plate, and an aeration mechanism and a tank wall cleaning mechanism respectively provided on the upper and lower surfaces of the sealing cover plate.

[0008] The opening and closing mechanism includes two mounting slots respectively formed in the front wall and the inner rear wall of the mounting opening. Guide rods are fixedly connected to the inner walls on both sides of the front mounting slot, and guide blocks are slidably connected to the surface of the guide rods. Reciprocating screws are rotatably connected to the inner walls on both sides of the rear mounting slot, and threaded blocks are threadedly connected to the surface of the reciprocating screws. The opposite surfaces of the guide blocks and the threaded blocks are fixedly connected to the front and back of the sealing cover, respectively. A motor is fixedly installed on the back of the pool body, and the output shaft of the motor extends into the interior of the rear mounting slot. Bevel gears are fixedly connected to the surface of the reciprocating screw and the end of the motor output shaft.

[0009] In a preferred embodiment, the pool wall cleaning mechanism includes two water pipes and two cleaning rods symmetrically installed on the lower surface of the sealing cover. The water pipes have water outlet holes on the side adjacent to the inner wall of the pool. The housing of the sealing cover has water passage cavities that communicate with the interior of the two water pipes. A water pump is fixedly installed on the upper surface of the sealing cover, and the water outlet of the water pump extends into the interior of the water passage cavity.

[0010] The inner wall of the pool can be flushed by using a water pump and water pipes.

[0011] In a preferred embodiment, the number of water outlet holes is several, and the several water outlet holes are equally spaced on the surface of the water pipe.

[0012] In a preferred embodiment, both cleaning rods are rotatably connected to the lower surface of the sealing cover. The lower end surface of the cleaning rod is provided with bristles, and the upper end surface of the cleaning rod is fixedly installed with a transmission gear. The inner front wall and inner rear wall of the pool are both provided with rack grooves that mesh with the transmission gear.

[0013] By incorporating a transmission gear, rack and pinion groove, and cleaning rod, the cleaning rod can be rotated via the transmission gear when the sealing cover moves, and the brush bristles will sweep and brush the inner wall of the pool, improving the cleaning effect of the pool wall.

[0014] In a preferred embodiment, the aeration mechanism includes an installation cylinder embedded in the upper surface of the sealing cover plate, the upper end of the installation cylinder having a first vent, the upper end of the installation cylinder being fitted with a cover, and the surface of the cover having a second vent adapted to the first vent.

[0015] By setting up the first and second vents, the tank can be depressurized and ventilated. The air intake and exhaust volume can be controlled by rotating the cover to adjust the opening size of the first and second vents.

[0016] In a preferred embodiment, the inner wall of the cover is provided with an installation ring, and the surface of the mounting cylinder is provided with an annular groove adapted to the installation ring. The cover is rotatably connected to the surface of the mounting cylinder through the installation ring and the annular groove. Angle brackets are installed on both sides of the cover, and fastening bolts are threaded onto the surface of the angle brackets.

[0017] In a preferred embodiment, the two sides of the pool are respectively provided with an inlet pipe and an outlet pipe.

[0018] As can be seen from the above, the sealing device for a water treatment filter provided by this utility model has the following technical effects.

[0019] Firstly, when the tank needs to be fully opened, the motor drives the reciprocating screw to rotate through the bevel gear. Under the conductive action of the guide slider and guide rod, the threaded block can cause the reciprocating screw to rotate, which in turn drives the sealing cover to move left and right in the installation opening until the sealing cover moves to the left and fully opens the tank, thus facilitating the opening and closing of the oxidation tank.

[0020] Secondly, the movement of the sealing cover drives the transmission gear to roll in the rack groove. The rolling of the transmission gear drives the cleaning rod and brush to sweep the inner wall of the pool. At the same time, the operation of the water pump draws external water into the water passage chamber. The water in the water passage chamber enters the interior of two water pipes and is sprayed out through several water outlets to rinse the inner wall of the pool. Combined with the sweeping of the brush, it can achieve a high degree of cleaning effect on the inner wall of the pool, which facilitates the subsequent cleaning work of the oxidation pool.

[0021] Thirdly, when aeration is required inside the tank, rotate the cover at the top of the mounting cylinder until the second vent on the cover surface is connected to the first vent on the mounting cylinder. At this point, air can be vented and introduced into the tank. By controlling the rotation angle of the cover, the size of the opening between the second and first vents can be adjusted, thereby controlling the amount of air vented and introduced, achieving the aeration effect and further improving the practicality of the sealing device.

[0034] The two sides of the pool body 1 are respectively provided with an inlet pipe and an outlet pipe.

[0035] Reference Figure 5 , Figure 6 and Figure 7 In a preferred embodiment, the pool wall cleaning mechanism includes two water pipes 9 and two cleaning rods 10 respectively symmetrically installed on the lower surface of the sealing cover plate 2. The water pipes 9 have water outlet holes 11 on the side adjacent to the inner wall of the pool body 1. The housing of the sealing cover plate 2 has water passage cavities 12 that communicate with the interior of the two water pipes 9 respectively. A water pump 13 is fixedly installed on the upper surface of the sealing cover plate 2. The water outlet end of the water pump 13 extends into the interior of the water passage cavity 12, and the water pumping end of the water pump 13 is connected to an external water source.

[0036] The inner wall of the pool 1 can be flushed by the water pump 13 and the water pipe 9.

[0037] There are several water outlet holes 11, which are equidistantly arranged on the surface of the water pipe 9.

[0038] Both cleaning rods 10 are rotatably connected to the lower surface of the sealing cover plate 2. The lower end surface of the cleaning rod 10 is provided with bristles 14, and the upper end surface of the cleaning rod 10 is fixedly installed with a transmission gear 15. The inner front wall and inner rear wall of the pool body 1 are provided with rack grooves 16 that mesh with the transmission gear 15.

[0039] With the arrangement of the transmission gear 15, rack groove 16 and cleaning rod 10, the cleaning rod 10 can be driven to rotate by the transmission gear 15 when the sealing cover plate 2 moves, and the inner wall of the pool body 1 can be swept and brushed by the bristles 14, thereby improving the cleaning effect of the pool wall.

[0040] Reference Figure 2 , Figure 3 and Figure 8 In a preferred embodiment, the aeration mechanism includes an installation cylinder 17 embedded in the upper surface of the sealing cover plate 2. The upper end of the installation cylinder 17 is provided with a first vent 18, and the upper end of the installation cylinder 17 is fitted with a cover 19.

During this process, the movement of the sealing cover 2 drives the transmission gear 15 to roll in the rack groove 16. The rolling of the transmission gear 15 drives the cleaning rod 10 and brush 14 to sweep and brush the inner wall of the pool body 1. At the same time, the operation of the water pump 13 pumps external water into the water passage chamber 12. The water in the water passage chamber 12 flows into two channels respectively. The water pipe 9 sprays water through several outlet holes 11 to rinse the inner wall of the tank 1. Combined with the brush bristles 14, it can achieve a high degree of cleaning of the inner wall of the tank 1. When it is necessary to aerate the inside of the tank 1 during the use of the oxidation tank, rotate the cover 19 at the upper end of the mounting cylinder 17 until the second vent 20 on the surface of the cover 19 is connected to the first vent 18 on the mounting cylinder 17. At this time, air can be discharged and introduced into the tank 1. By controlling the rotation angle of the cover 19, the size of the opening between the second vent 20 and the first vent 18 can be adjusted, thereby controlling the discharge and intake volume and achieving the aeration effect.
