[0025] Reference Figure 1 , Figure 3 A water inlet butt joint 20 is fixedly connected to the top right side of the exterior of the tank body 1, a water outlet butt joint 21 is fixedly connected to the bottom left side of the exterior of the tank body 1, an L-shaped sedimentation tube 22 is fixedly connected to the bottom of the tank body 1, and impurities can be deposited here.

A plurality of fixed legs 27 are fixedly connected to the bottom of the outer wall of the tank body 1.

[0026] Compared with some devices in the prior art, the above content is that the threaded tube 5 outside the screw rod 3 is driven to move by controlling the circular turning handle 4 so that the connecting block 6 drives the tank cover 7 to move, and the tank cover 7 and the base 18 are connected by a quick locking member, so that the device can be opened and closed for maintenance more conveniently, so that impurities inside the device can be effectively cleaned.

[0027] Working principle: Water enters the tank 1 from the water inlet butt joint 20. The water flows through the cylindrical filter 19, which is designed to allow water to flow through while intercepting impurities. Impurities in the water are collected by the circular scraper 12 and pushed to the bottom of the tank 1. The circular scraper 12 is driven by the cylinder 10 and connected by the drive shaft 11, so that it can move up and down inside the tank 1, effectively removing impurities attached to the filter.

[0028] As the filtration process proceeds, impurities gradually accumulate in the L-shaped sedimentation tube 22 at the bottom of the tank 1. This design allows heavy impurities to be concentrated in one area, facilitating subsequent cleaning work. The water outlet butt joint 21 of the tank 1 is located on the other side of the bottom of the tank 1, ensuring that clean water can be discharged from the tank 1 for continued recycling or discharge.

[0029] When maintenance or cleaning is required, the operator can rotate the circular handle 4, which drives the threaded tube 5 to move through the screw rod 3. The movement of the threaded tube 5 drives the connecting block 6 and the tank cover 7, so that the tank cover 7 can be opened or closed. The opening of the tank cover 7 provides a passage to access the inside of the tank body 1, which is convenient for cleaning and maintenance. The connection between the tank cover 7 and the base 18 is achieved by a quick locking member. This design supports fast opening and closing operations and improves maintenance efficiency.

[0030] After cleaning, the tank cover 7 is closed again and locked by the reverse operation of the round handle 1 4 and the threaded tube 5. The ball 24 provides an additional control mechanism at the end of the L-shaped sedimentation tube 22, and the position of the ball 24 is adjusted by rotating the round handle 26 to control the opening and closing of the water hole 25 to manage the discharge of sediment or keep it inside the tank body 1.
