Precipitation and concentration integrated low-disturbance bottom mud precipitation device

Abstract

The invention discloses a precipitation and concentration integrated low-disturbance bottom mud precipitation device. The precipitation and concentration integrated low-disturbance bottom mud precipitation device comprises a tank body and a bottom mud pushing device. The tank body comprises a bottom plate, side plates and a partition plate, the bottom plate and the side plates define a water tankshape, the partition plate is arranged in the tank to divide the tank body into a precipitation bin and a concentration bin, holes are formed in the bottom of the partition plate to connect the precipitation bin with the concentration bin, and the bottom mud pushing devices are arranged in the precipitation bin and the concentration bin. The bottom mud pushing device is a rotary auger and comprises transverse augers and a longitudinal auger. The main sections of the transverse augers are located at the bottom of the precipitation bin, and one end of each transverse auger penetrates through thecorresponding hole in the bottom of the partition plate and is located in the concentration bin. The longitudinal auger is arranged at the bottom in the concentration bin, the axis of the longitudinal auger is in the length direction of the concentration bin, a pit is further formed in the bottom of the concentration bin, and a slurry pump is arranged in the pit. The cross section of the bottom plate is in a continuous V shape, and the multiple transverse augers are located at the bottom of a V-shaped groove of the bottom plate.

Description

technical field [0001] The invention relates to the field of lake management, in particular to a low-disturbance sedimentation device integrating sedimentation and concentration. Background technique [0002] An important operation in lake governance is to remove the bottom mud. The bottom mud boat drives on the lake and sucks up the bottom mud through the suction head. However, the sucked up bottom mud contains a lot of water, and because of When the mud pump is used, the mud and water are fully mixed together. When the mud-water mixture with a large water content is directly processed to the subsequent sediment, it needs to consume a lot of energy to transport water, which is completely unnecessary. Therefore, the sediment is generally pumped. After coming up, carry out preliminary precipitation to remove water. [0003] In the prior art, the sedimentation tank only uses a large pond. When the sediment at the bottom is collected and the mud-water mixture enters, the sedim...

Problems solved by technology

[0003] In the prior art, the sedimentation tank only uses a large pond. When the sediment at the bottom is collected and the mud-water mixture enters, the sedimentation tank will be stirred, resulting in insufficient sedimentation or the sediment that has settled is stirred up to affect the collection. The residence time Too long leads to low processing efficiency
