Slurry reduction treatment system

Abstract

The invention discloses a mud reduction treatment system, which is composed of a mud extraction device, a mud removal and purification device, and a chemical agent treatment device connected in sequence, and is characterized in that the mud removal and purification device includes a mud storage tank, which is arranged The double-layer screen above the slurry tank, the main engine slurry pump, the cyclone, the middle storage tank and the first mud pool, the double-layer screen is composed of the lower double-layer coarse screen layer and the upper double-layer fine screen layer Composition, the inlet of the desilting and purification device is located above the coarse screen layer of the double-layer screen, the slurry storage tank is connected to the cyclone through the main engine slurry pump, the overflow of the cyclone is connected to the middle storage tank, and the underflow of the cyclone The outlet is located above the fine sieve layer of the double-layer sieve, and the mud outlet of the middle storage tank is connected to the first mud pool. The invention can effectively separate the mud and the waste residue, can reuse the mud, can also use the chemical agent plus centrifugal method to separate the mud from water, and guarantee the separation effect.

Description

technical field [0001] The invention relates to a mud processing method, in particular to a method for reducing the amount of construction mud. Background technique [0002] During building construction, for example during the construction of pile foundations, a large amount of mud is produced. Construction mud has a high water content (usually up to 70% to 80%), which is difficult to handle and will have adverse effects on the environment. Therefore, it is necessary to reduce the amount of mud to reduce the cost of mud transportation, reduce environmental pollution and realize the recycling of water resources. [0003] In the article "Application of centrifuge system in the process of construction mud reduction" in the fifth issue of "Construction Technology" in 2015, a centrifuge treatment system is disclosed, which consists of a mud inlet pump, a decanter centrifuge, and a dosing device. Composed of five components, compound feeding device and conveyor, the construction...

AI Technical Summary

Problems solved by technology

[0004] This technical solution can reduce the amount of mud. However, due to the use of the mud storage tank agitator, flocculant, and centrifuge, the viscosity of the mud to be treated is relatively consistent, and the mud particles contained in it should not be too large, otherwise it will cause system damage. Not working properly, not even able to achieve mud reduction treatment

[0005] However, in practical applications, the pumped mud usually contains both the slurry part with a large water content and soil clods of different sizes. If the above-mentioned system is used for treatment, pipeline blockage, agitator overload damage, and even The centrifuge is malfunctioning, making it difficult for the system to function properly
