Role of crushing grid in Zhejiang Xinzhao environmental protection integrated sewage pump station:
Whether it is an integrated sewage pump station or an integrated rainwater lifting pump station, an important part of its structure is the grid system, which is divided into basket grid and crushing grid. Both of them are used to block garbage, prevent pipe blockage, and clean up sundries in time.
The difference between the two is that the basket grid is a grid device made of stainless steel, which blocks the large garbage entering the pump station and prevents the sewage pump and pipeline system from blocking. However, there are also some disadvantages. When the grid garbage is blocked to a certain extent, it needs to be cleaned regularly.
The crushing grid is a new type of crushing equipment that can crush the solid substances in the sewage flowing through the pipeline into fine particles. It can crush the wood chips, empty bottles, cloth pieces and other sundries in the sewage pipe network, so as to protect the equipment of the integrated prefabricated pump station and make it operate normally.
Generally, the crushing grid is used for the integrated sewage pump station, and the basket grid is used for the integrated rainwater pump station.
However, the crushing grid plays an indispensable role in the integrated sewage pump station. When the general urban sewage passes through the municipal pipe network, it will be mixed with a variety of solid wastes, such as branches, leaves, plastic bags, etc. A large amount of garbage will cause the pipe to be blocked. The function of the crushing grid is to crush the solid substances in the sewage into tiny particles, which can not be salvaged. At the same time, it can protect the follow-up treatment equipment (blockage / winding / jamming), improve the follow-up treatment effect, improve the water quality, etc. After the solid substances in the sewage enter the crusher with the water flow, the solid substances are intercepted by the rotating blade and transported to the cutting room, and are crushed into 6~10mm fine particles by the cutting blade. Most of the sewage and sufficiently small particles directly pass through the gap between the blades and flow to the subsequent process together with the crushed small particle substances for treatment.
