AI Technical Summary

Technical Problem

In the existing technology, carbide slag has a high moisture content and uneven particle size. Directly feeding it into the pulping pool results in large pulping particles containing impurities, which corrodes downstream equipment. At the same time, acetylene gas accumulation is difficult to accurately detect, posing a safety hazard.

Method used

A crushing and separation device is designed, which uses the inclined first and second wall plates to form a crushing space, and provides an interface pipe at the upper part to connect to the pressurized filtered water source. The carbide slag is crushed and separated by the impact of water flow, and is combined with a combustible gas detector and an alarm device to ensure safety.

Benefits of technology

Effectively crush carbide slag into small particles, reduce abrasion to downstream equipment, improve safety, ensure the accuracy of acetylene gas detection, and reduce safety hazards.

Abstract

The present invention relates to the field of crushing and separation technology, and discloses a crushing and separation device for carbide slag, the crushing and separation device comprising: a shell (1), the shell comprising a first wall plate (101) and a second wall plate (102) extending obliquely downward relative to the vertical direction, and a side wall plate (103) connected between the first wall plate and the second wall plate and arranged vertically, the first wall plate, the second wall plate and the side wall plate enclosing a crushing space (104); an interface pipe (2), the interface pipe being used to connect a pressurized filtered water source, the interface pipe being arranged at the upper part of the crushing space and arranged on the first wall plate towards the second wall plate, so as to impact and crush the carbide slag falling from the upper part of the shell toward the second wall plate. The present invention solves the technical problem that the conventional carbide slag is directly fed into the pulping tank, the pulping particles are large and contain impurities, which causes abrasion to downstream equipment.
