Skid-mounted type building mud treatment device and process

Abstract

The invention discloses a skid-mounted type building mud treatment device and process. The treatment device comprises a mud homogenizing tank, a screw overlapped type sludge dehydrator, a sludge storage tank, a sludge conveying pump, an agent preparation system, an agent adding pump and an electrical control cabinet which are installed on an overall base or in a container. The mud homogenizing tank comprises mud homogenizing stirring tanks and a mud and agent mixing stirring tank. The mud homogenizing tank is longer in retention time after being improved, and mud is mixed more uniformly and is not prone to settle. The screw pitch is in special reducing design after a screw shaft of the screw overlapped type sludge dehydrator is improved, the spiral angle is gentler, and an abrasion-resistant layer is thicker. Through special structural design, the building mud is rapidly dehydrated on the overall base or in the container, a whole system is high in integration degree, the occupied place is small, the mass is low, the size is small, mobility, environmental protection performance and dehydration speed are high, the effect is good, outward transport disposal cost is reduced, and treated soil can be directly modified and resourcefully utilized.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a skid-mounted construction mud treatment device and a treatment process. Background technique [0002] With the continuous advancement of my country's urbanization process, urban construction is changing with each passing day, and there are more and more constructions of high-rise, super high-rise buildings, subways, expressways, large bridges and other projects, and the resulting amount of construction mud is extremely huge. The composition and properties of these sludges are different from those of municipal sludge. They are mainly clay minerals, and the effects of natural settlement and direct dehydration are poor. If they are not handled properly, they will easily cause environmental pollution, damage water quality, and block municipal pipelines. Due to the high moisture content of the mud, most of the actual transported mud is water when the mud is directly t...

AI Technical Summary

Problems solved by technology

[0005] 1) Excavating pits, dams, gathering, and natural air-drying at the construction site. This method requires a large amount of space, a long air-drying period (about five years), difficult land reclamation, ecological damage and unsafe;

[0006] 2) Conventional dehydration equipment is placed on the construction site, which occupies a large space and the connection of pipelines is complicated; it needs to be temporarily taken over on site, with long construction period and low space utilization rate;

[0007] 3) Compared with municipal sludge, construction mud has more gravel content, higher specific gravity, higher proportion of inorganic matter in sludge, faster sedimentation, and uneven sludge concentration. If it is directly processed into conventional dehydration equipment, it will lead to mud discharge Moisture content is sometimes high and sometimes low, and the mud output effect is not stable
