Cleaning machine:

A cleaning machine is a mechanical equipment used to remove debris and dirt from water flow. Its main function is to intercept and remove floating debris, branches, leaves, garbage, etc. in the water, to ensure smooth water flow and normal operation of subsequent equipment. There are various types of cleaning machines, including rotary cleaning machines, grab type cleaning machines, etc., which can adapt to different working conditions and water environments. It has the characteristics of high cleaning efficiency and easy operation, and is widely used in water conservancy engineering, sewage treatment plants, pump stations and other places.

Grille cleaning machine:

The grid cleaning machine is a special type of cleaning machine. It intercepts large suspended solids and impurities in sewage by setting up a grid. A grid is usually composed of a series of parallel bars, and when sewage flows through, the pollutants are intercepted by the grid. The grid cleaning machine can continuously and automatically remove the dirt intercepted by the grid, maintaining the cleanliness of the grid. It can be divided into mechanical grid cleaning machines and manual grid cleaning machines, etc. The grid cleaning machine plays an important role in fields such as sewage treatment and urban drainage, effectively preventing pipeline blockage and equipment damage, and improving the operational efficiency and stability of water treatment systems. Its advantages include reliable operation, simple maintenance, and good cleaning effect.

Structurally, it usually consists of parts such as a door seat, door leaf, hinge shaft, etc.

The working principle is that when the water flows out from the pipeline or channel, the flap door opens under the impact of the water flow; When the water flow stops or flows in the opposite direction, the flap door quickly closes by its own gravity or under the action of water pressure, thereby preventing the water from flowing back.

The main characteristics of a shutter are: simple structure, convenient installation, and low cost; It has less resistance to water flow and relatively better water passing capacity.

It has a wide range of applications in water conservancy engineering, municipal drainage, and other fields, especially suitable for situations with high requirements for anti backflow.

In summary, the flap door is a common and practical hydraulic equipment that plays an important role in ensuring the normal operation of drainage systems and preventing water flow backflow.
