The width of the gap between the light pedal grid bars can be set according to the way of removing dirt and the requirements of the water pump. The gap between the manually removed grids is generally 16~25mm. The grid in front of the grit chamber or sedimentation tank is generally 15-30mm, and the larger one is 40mm. There are three types of mechanical slag cleaning equipment in common use, namely chain type, mobile type and wire rope (composed of steel wire, rope core and grease) traction type lattice trash cleaning machine. According to the size of the grid spacing, the grid is divided into three types: thick grid, medium grid and fine grid. According to the grid, there are three kinds of slag removal methods: manual grid, mechanical grid and hydraulic grid.
Dalian light steel mesh can be divided into grabbing type, circular type, arc type (explanation: it is an elegant line), rotary type, rotary drum type, rotary type, tooth harrow type and ladder type according to different grid structure characteristics. The grid equipment is generally used on the inlet channel of sewage treatment or at the inlet of the sump tank of the lift pump station. It is mainly used to remove large suspended or floating objects in the sewage, so as to reduce the treatment load of the subsequent water treatment process and protect the water pump, pipeline, instrument, etc. When the amount of slag intercepted is greater than 0. At 2m3/d, mechanical slag removal is generally adopted; Slag amount is less than 0. When 2m3/d, manual slag removal or mechanical slag removal can be used. The application of lattice is widely used in building construction, design and decoration, sewage treatment, engineering application and other fields.
