Description

Screw type pool bottom sludge cleaning device

Technical Field

The utility model relates to a desilting equipment, in particular to screw bottom of pool mud desilting device.

Background

The washed sand is sand in a river channel or sand on an old riverbed is washed and classified to separate sand of various grades and specifications, the production area is wide in distribution, compared with quartz sand, the cost is low, and the washed sand has the advantages of good construction fluidity and stable quality particularly in the building industry.

The sand washing field and the concrete prefabricated product front end sand washing wastewater contain a large amount of silt and suspended solids, and in a treatment facility, although partial large-particle sand is removed through pretreatment processes such as a grit chamber and the like, a large amount of silt still enters a rear end adjusting tank, so that a large amount of silt is deposited and hardened at the bottom of the tank, and the silt is pre-deposited at the bottom of the tank for a long time to cause abrasion of a rear end water pump and reduce the effective water storage volume of the tank body.

The conventional treatment method is to install a submersible mixer, an aeration pipe or a mud scraper in the tank, but the three methods have the following problems. 1. The submersible mixer is used for stirring up the silt at the bottom of the pool through the high-speed rotation of the blades to enable the silt in the pool to be in a suspended state, but by adopting the mode, the silt content in the pool is higher, and the suspended silt in water can cause the abrasion of the blades when the blades rotate at a high speed; secondly, the submersible mixer is used for mixing, dead corners exist in the pool, and silt in the dead corner area can be slowly accumulated. 2. Aeration and stirring, namely, an aeration pipeline is arranged at the bottom of the tank by using an aeration pipeline, and a large amount of air is aerated by an aeration fan to stir up suspended matters at the bottom of the tank, but the mode is firstly that the energy consumption is overhigh, and secondly, the aeration has better stirring effect on the suspended matters with smaller specific gravity in the water body, but the stirring effect on the impurities such as silt with larger specific gravity is not ideal; finally, the silt in the water is easy to block the aeration pipeline. 3. The mud scraper adopts a scraper to scrape the mud at the bottom of the pool to a mud collection pool, but if the mud collection at the bottom of the pool body is excessive, the mud scraping amount of the scraper increases, so that the actual load of the mud scraper increases, namely the torque of a mud scraping shaft of the mud scraper increases, and when the torque does not exceed the maximum torque which can be provided by the mud scraper and the strength of the shaft is enough, the mud scraper can still operate; when the maximum torque which can be provided by the mud scraper is exceeded, the motor does not rotate, the motor can be damaged, and the scraper can also be deformed and damaged after long-time operation.

Therefore, a dredging device with better dredging effect is needed.
