Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment technology, and in particular to a water tank with no dead angles for water treatment. Background Technology
[0002] In the existing water treatment field, water tanks are important equipment for storing and transferring sewage or purified water, and their design and function are directly related to the efficiency of water treatment and the safety of water quality.
[0003] Traditional water tanks often employ rectangular or cylindrical structures. While these structures are simple to manufacture, they frequently create unavoidable dead-angle areas during actual use. These dead-angle areas not only easily accumulate contaminants, becoming breeding grounds for bacteria, but also significantly increase the difficulty of cleaning and maintenance. Especially in water treatment environments requiring frequent cleaning and disinfection, the presence of dead-angle areas seriously affects the hygiene of the water tank and water quality safety. Furthermore, traditional water tank cleaning methods often rely on manual operation, which is not only labor-intensive and inefficient, but also makes it difficult to ensure thorough and uniform cleaning. Therefore, to solve the aforementioned problems, we propose a water treatment tank without dead-angle areas. Utility Model Content
[0004] The purpose of this utility model is to solve the defects existing in the prior art by proposing a water treatment tank with no dead angles.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A water treatment tank with no dead angle includes a water tank, which has a spherical structure. An opening is provided on the top of the water tank, and a detachable tank cover is installed at the opening. An inlet pipe is fixedly installed on the top of the tank cover, and an outlet pipe is fixedly installed on the bottom of the water tank. Multiple support legs are fixedly installed on the lower part of the outer surface of the water tank.
[0007] A rotating assembly is installed in the middle of the top of the tank cover. A lifting assembly is installed on the tank cover via the rotating assembly. A flushing pipe is installed inside the lifting assembly, and the bottom end of the flushing pipe extends into the interior of the water tank.
[0008] Furthermore, the rotating assembly includes a mounting bracket, a motor is fixedly mounted on the top of the inner side of the mounting bracket, a gear is fixedly mounted on the output end of the motor, a gear is rotatably mounted on the middle of the top of the cover, the gear and the gear are meshed together, the bottom end of the flushing pipe passes through the gear, and the lifting assembly is fixedly mounted on the top of the gear.
[0009] Furthermore, the lifting assembly includes a mounting box, inside which a second motor is fixedly installed. The upper and lower ends of the flushing pipe pass through the top and bottom of the mounting box, respectively. On one side of the outer surface of the flushing pipe, multiple protruding teeth are fixedly installed at equal intervals from top to bottom. A third gear is fixedly installed at the output end of the second motor, and the third gear meshes with the protruding teeth.
[0010] Furthermore, each of the mounting boxes has through holes, and a limiting strip is fixedly installed on the other side of the outer surface of the flushing tube. The flushing tube passes through the mounting box through two of the through holes, and two grooves that are adapted to the limiting strip and the protruding teeth are opened inside each of the two through holes.
[0011] Furthermore, a rotary joint is fixedly installed at the top of the flushing pipe, and multiple nozzles facing different directions are fixedly installed at equal intervals below the outer surface of the flushing pipe.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This invention, through its spherical structure design, effectively eliminates dead corners inside the tank, preventing the accumulation of pollutants and significantly improving the hygiene of the water tank and the safety of the water quality. The spherical structure also allows for full utilization of the tank's internal space, reducing blind spots and providing favorable conditions for automated cleaning.
[0014] This invention achieves automatic rotation and lifting of the flushing pipe through the design of a rotating component and a lifting component. This not only greatly improves the efficiency and uniformity of cleaning but also avoids the labor intensity and safety hazards associated with manual cleaning. The rotating component, driven by a motor and gear transmission, allows the flushing pipe to rotate in all directions, ensuring that every corner inside the water tank is thoroughly rinsed. The lifting component, driven by a motor and the meshing of gears and convex teeth, enables the flushing pipe to move up and down, further enhancing the flexibility and thoroughness of cleaning.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;
[0023] Reference Figure 1-5 A water treatment tank with no dead angle includes a water tank 1, which has a spherical structure. An opening is provided on the top of the water tank 1. A detachable tank cover 2 is installed at the opening on the top of the water tank 1. An inlet pipe 4 is fixedly installed on the top of the tank cover 2. An outlet pipe is fixedly installed on the bottom of the water tank 1. Multiple support legs are fixedly installed on the lower part of the outer surface of the water tank 1.
[0024] Water tank 1 can store wastewater or clean water in water treatment. Water can be introduced into water tank 1 through water inlet pipe 4 and the stored water can be discharged through water outlet pipe. The circular structure of water tank 1 can effectively eliminate dead corners inside the tank and prevent pollutants from accumulating in dead corners.
[0025] A rotating assembly is installed in the middle of the top of the tank cover 2. A lifting assembly is installed on the tank cover 2 through the rotating assembly. A flushing pipe 7 is installed inside the lifting assembly. The bottom end of the flushing pipe 7 extends into the interior of the water tank 1.
[0026] The rotating component can drive the lifting component to rotate, and cause the flushing pipe 7 to rotate. The lifting component can drive the flushing pipe 7 to move up and down. When the inside of the water tank 1 does not need to be cleaned, the flushing pipe 7 can be removed from the inside of the water tank 1. The flushing pipe 7 can introduce clean water into the inside of the water tank 1 to flush the inside of the water tank 1.
[0027] The rotating assembly includes a mounting bracket, on the top of the inner side of the mounting bracket a motor 3 is fixedly mounted, on the output end of the motor 3 a gear 8 is fixedly mounted, on the middle of the top of the cover 2 a gear 6 is rotatably mounted, the gear 6 meshes with the gear 8, the bottom end of the flushing pipe 7 passes through the gear 6, and the lifting assembly is fixedly mounted on the top of the gear 6.
[0028] Motor 3 can drive gear 8 to rotate, gear 8 can drive gear 6 to rotate, and after gear 6 rotates, it can drive the flushing pipe 7 to rotate through the lifting assembly, thereby thoroughly flushing the inside of the water tank 1.
[0029] The lifting assembly includes a mounting box 5, in which a second motor 10 is fixedly installed. The upper and lower ends of the flushing pipe 7 pass through the top and bottom of the mounting box 5, respectively. Multiple protruding teeth 12 are fixedly installed at equal intervals from top to bottom on one side of the outer surface of the flushing pipe 7. A third gear 13 is fixedly installed at the output end of the second motor 10, and the third gear 13 meshes with the protruding teeth 12.
[0030] Motor 2 10 can drive gear 3 13 to rotate. Gear 3 13 can drive flushing pipe 7 to move up and down through the tooth 12, thereby moving flushing pipe 7 upward out of the water tank 1 and preventing sewage in water tank 1 from contaminating flushing pipe 7.
[0031] Each mounting box 5 has a through hole 9. A limiting strip 14 is fixedly installed on the other side of the outer surface of the flushing pipe 7. The flushing pipe 7 passes through the mounting box 5 through two through holes 9. The interior of each through hole 9 has two grooves that are adapted to the limiting strip 14 and the protruding teeth 12. The grooves and the limiting strip 14 allow the mounting box 5 to rotate together with the flushing pipe 7 through the through holes 9.
[0032] A rotary joint 11 is fixedly installed at the top of the flushing pipe 7, and multiple nozzles 15 facing different directions are fixedly installed at equal intervals on the lower surface of the outer surface of the flushing pipe 7. The flushing pipe 7 can be connected to a water supply pipeline through the rotary joint 11. The setting of the rotary joint 11 can prevent the flushing pipe 7 from being unable to rotate due to the influence of the external pipeline. The nozzles 15 facing different directions can more thoroughly flush the inside of the water tank 1, and can more thoroughly clean the inside of the water tank 1.
