In industrial production and processing, many industrial wastewaters contain fine suspended solids, which are difficult to remove by sedimentation, so they must be intercepted during the grid decontamination process. At this time, the role of the screen is very obvious, and only the appropriate type of screen can intercept the suspended matter of the corresponding size. Therefore, when choosing a coarse grid, attention should be paid to the selection of the screen.

The screen is generally made of metal wire or chemical fiber, which has low operating cost, small footprint and easy maintenance. It is especially suitable for sewage treatment projects with fine impurities. The screen does not add any chemical substances, has no effect on the water source, and has a simple structure and high efficiency.

There are three types of screens commonly used by general users, namely rotary screen, hydraulic rotary screen and vibrating screen. Rotary screen can be divided into inner water inlet rotary screen and outer water inlet rotary screen. At present, the most widely used form in China is the inner water drum screen.

Stainless steel rakes may have deformation problems when using coarse gratings, so why is there deformation problems? How should attention be paid to prevent the above phenomenon?

The main reason is that there is too much dirt and high concentration in the flood season, which causes the single rake to be overloaded, and the rake tube deforms and causes failure. The rake tube is an important moving part of the rotary cleaning machine, which plays a dual role of supporting the chain and preventing the chain from derailing and scouring the dirt. The middle part is the weak link of the whole body, and many related problems, such as chain plate twisting, broken chain, etc., are mostly caused by the deformation of the rake tube, so its strength and rigidity must be sufficient.

For larger-sized rotary cleaners, multiple traction chains can be considered to improve the force-bearing condition of the rake tube, or the middle of the rake tube can be locally strengthened to make it a variable-section force-bearing member.

Coarse grille is an indispensable power in industrial production, without grille mechanical equipment can not work properly. Here are two ways to make a thick grid, I hope it will help you.

Because the power grid of my country's hydroelectric power generation machinery is restricted by the flood season of the water source, the power grid of hydropower generation machinery is unstable.

In recent years, on the one hand, due to the increasing shortage of coal resources, coal prices have risen, and on the other hand, due to the emphasis on the environmental protection work of fire-fighting coarse grille factories, fire-fighting coarse grille factories in various places have carried out environmental protection renovations. The increase in the cost of the coarse grille factory will inevitably lead to an increase in the price of the coarse grille.
