Description

TECHNICAL FIELD

[0001] The utility model relates to sewage pretreatment technical field, concretely is a V type diversion grit chamber. BACKGROUND

[0002] Sewage inevitably mixes mud and sand during migration, flow and collection. If the sand in the sewage is not pre-separated and removed, it will affect the operation of subsequent treatment equipment. The most important thing is that it will wear out the pump and block the pipe network, affecting and even destroying the subsequent treatment process effect. The grit chamber is mainly used for removing sand particles with a particle size greater than 0.2mm and a density greater than 2.65t / m 3 to protect the facilities such as pipes and valves from wear and blockage. Its working principle is based on gravity separation, so the inflow velocity of the grit chamber should be controlled to make the inorganic particles with high specific gravity sink, and the organic suspended particles can be taken away with the water flow. The grit can be removed by using a grating machine. At present, there are various V type diversion grit chambers on the market, but there are still some shortcomings.

[0003] The existing V type diversion grit chamber cannot improve the flow rate of sewage, which greatly reduces the efficiency of sand setting, etc. For example, the Chinese utility model patent with the authorization announcement number CN205965271U discloses a cyclone grit separation device, which includes a cyclone grit chamber. The cyclone grit chamber includes an inlet channel, a grit chamber, an outlet channel, and a sand collecting hopper arranged at the bottom of the grit chamber. A paddle driven by a motor is arranged in the grit chamber. A sand discharge mechanism is arranged in the sand collecting hopper. An annular flow guide plate is arranged at the upper part of the grit chamber. The cross section of the flow guide plate is V-shaped, the outer diameter is smaller than the inner diameter of the grit chamber, and the height is smaller than the height of the grit chamber. An inclined conveyor belt is arranged on the inlet channel. An arc-shaped groove is arranged at the bottom of the inlet channel to accommodate the front end of the conveyor belt. The track of the conveyor belt is made of a filter screen, and a plurality of sand filtering grooves are uniformly distributed on the track. The device has a simple structure and is easy to use. However, the device drives the paddle to rotate by the motor, thereby improving the flow rate of the sewage and increasing the load of the facility. After the sand setting of the sewage is completed, the sand at the bottom of the grit chamber cannot be quickly removed, which affects the efficiency of subsequent sand setting. Therefore, we propose a V type diversion grit chamber to solve the problems mentioned above. CONTENT OF THE UTILITY MODEL

In the process of sewage flow, the sewage enters the branch drainage channels 2, which can be divided into two parts for dispersed sand setting, so as to reduce the load of subsequent water treatment facilities, reduce the project land occupation and investment, and change the width and slope of the sewage entering the branch drainage channels 2 from the main channel 1, that is, improve the flow rate of the sewage. When the sewage enters the sand setting tank body 3 below the branch drainage channels 2, the rotation speed is increased, so as to improve the sand setting efficiency. Meanwhile, support frames 4 and stabilizing frames 5 are installed below the outer sides of the branch drainage channels 2 to firmly support them. Since the collecting boxes 6 are installed below the inside of the sand setting tank body 3, the mud sand quickly sinks into the inside of the collecting boxes 6, and the clean water is discharged from the discharge channels 19 installed at the rear side of the sand setting tank body 3. The connection part between the discharge channels 19 and the sand setting tank body 3 is provided with a filter screen 17.
