Continuous kneading and crushing device

Abstract

The invention provides a continuous kneading and crushing device. The continuous kneading and crushing device comprises a conveying mechanism and a kneading and crushing mechanism located above the conveying mechanism. The kneading and crushing mechanism comprises first crushing rollers and second crushing rollers; the first crushing rollers and the second crushing rollers are arranged in a staggered mode in the conveying direction of the conveying mechanism. In the actual implementation process, the conveying mechanism conveys a mixed material formed by mixing a mud cake, an improved material and a moisture adjusting material into the kneading and crushing mechanism, the mixed material is kneaded and crushed through the first crushing rollers and the second crushing rollers, and a large mud cake block is crushed; the mud cake, the improving material and the moisture adjusting material are fully mixed to form small aggregates with uniform sizes; therefore, uniform feeding and metering of the soil are realized; the improved material can effectively reduce the viscosity of the mud cake, and the moisture adjusting material can adjust the moisture content of the mud cake, so that the characteristics of the mud cake are changed, the mud cake is prevented from adhering to equipment, the equipment can operate normally, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mud treatment, in particular to a continuous kneading and crushing device. Background technique [0002] The mud and muddy water that will be produced during the excavation and construction of construction projects will also produce a large amount of sludge in the process of wet sand making and sand washing, and the sludge will be discharged indiscriminately, which will cause serious environmental pollution problems; the sludge produced in construction projects The treatment of mud cake after dehydration has always been a major problem in the engineering field. There are at least the following problems in the prior art: [0003] 1. The mud cakes are agglomerated into lumps with different sizes, making it difficult to achieve uniform feeding and metering of soil. [0004] 2. The mud cake is highly viscous and sticks everywhere, causing the equipment to hold the shaft and stick to the material, which affe...

AI Technical Summary

Problems solved by technology

[0003] 1. The mud cakes are agglomerated into lumps with different sizes, making it difficult to achieve uniform feeding and metering of soil

[0004] 2. The mud cake is highly viscous and sticky everywhere, causing the equipment to hold the shaft and stick to the material, which affects the operation of the equipment

[0005] 3. The existing mud treatment equipment adopts intermittent production mode, which has low production efficiency and small processing capacity, and it is difficult to achieve a large processing capacity.
