Long-term supply of steel grating

Steel grating is also called grating, steel grating or grating, which is welded by flat steel and twisted steel. Steel grille is durable and more affordable compared to other products. Its main uses are power plant platforms, parking lot platforms, maintenance platforms, drain covers and treads. It is also used in environmental protection equipment and sewage treatment. Because of its superiority, it is more and more widely used.

The width of the gap between the grid bars can be set according to the method of removing dirt and the requirements of the water pump. The gap between the manual cleaning grids is generally 16~25mm. The grit in front of the grit tank or sedimentation tank is generally 15-30mm, and the maximum is 40mm. There are three commonly used mechanical slag cleaning equipment, namely chain type, mobile type and wire rope traction grille cleaning machine.

According to the size of the grid bar spacing, the grid is divided into three types: coarse grid, medium grid and fine grid. According to the grill cleaning method, there are three kinds of artificial grill, mechanical grill and hydraulic cleaning grill. According to the different characteristics of the grille structure, it can be divided into multiple forms such as grab rake, circulation, arc, rotary, drum, rotary, tooth rake and stepped. The grille equipment is generally used on the inlet channel of sewage treatment or at the entrance of the lifting pump station collection basin. The main function is to remove the large suspended or floating matter in the sewage, so as to reduce the processing load of the subsequent water treatment process and play a Protect water pumps, pipelines, meters, etc. When the amount of slag intercepted is greater than 0.2m3/d, mechanical slag removal is generally adopted; when the amount of slag intercepted is less than 0.2m3/d, manual or mechanical slag removal can be used.

The application of the grille has a wide range of uses in the fields of construction, design and decoration, sewage treatment, and engineering applications.
