Intelligent heat dissipation system for coal mining machine

Abstract

The invention discloses an intelligent heat dissipation system for a coal mining machine. The intelligent heat dissipation system for the coal mining machine comprises a heat dissipation controller, a refrigeration water tank, a water supply pipeline and a water return pipeline, multiple temperature detection units, multiple water cooling heat dissipation pipelines, multiple flow controlling valves, multiple flow detection units, an electric water pump, and multiple valve opening degree detection units, wherein the multiple temperature detection units are arranged on multiple portions which need to dissipating heat of the coal mining machine, and the electric water pump is mounted on the water supply pipeline. Two ends of the multiple water cooling heat dissipation pipelines are connected with the main water supply pipeline and the water return pipeline through a three-way pipe. The heat dissipation controller controls the electric water pump according to information detected by the multiple valve opening degree detection units and controls the multiple flow controlling valves according to information detected by the multiple temperature detection units. The intelligent heat dissipation system for the coal mining machine is reasonable in design, convenient to arrange, easy to operate, high in intelligent degree, and good in use effects. Heat of the multiple portions which need to dissipating heat is dissipated intensively through one electric water pump, and at the same time, flow of each water cooling heat dissipation pipeline can be adjusted according to the actual situation.

Description

technical field [0001] The invention relates to a heat dissipation system, in particular to an intelligent heat dissipation system for a coal mining machine. Background technique [0002] A coal shearer is a coal mining machine that breaks coal with a rotating working mechanism and reloads the broken coal into a conveyor or other transportation equipment. It is one of the key and indispensable equipment in coal mining machines. , plays a vital role in the entire coal mining process. The mechanism and function of the shearer itself are relatively complex. It is a large and complex system integrating machinery, electricity and hydraulic pressure, and the working environment is harsh. It is affected by the geological environment of the coal mining area and the geographical environment of the coal mining roadway where it is located. Larger, once the shearer breaks down in the actual working process, the entire coal mining work will be interrupted, resulting in huge economic los...

AI Technical Summary

Problems solved by technology

Nowadays, when water-cooling devices are used to perform water-cooling and heat-dissipation treatment on multiple parts of the coal mining machine that need heat dissipation, multiple circulating water pipes are usually used to dissipate heat separately, and each heat-dissipating pipe is independent of each other, so it is impossible to realize multiple heat-dissipating parts. Centralized heat dissipation control of parts

However, in the actual use process, the heat dissipation equipment installed on the existing coal mining machines has various defects and deficiencies such as inconvenient operation, low intelligence, high energy consumption, and poor heat dissipation effect to varying degrees.
