Embodiment Construction
[0009] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0010] Depend on figure 1 , figure 2 Given, the present invention is by its structure, is made up of the cutting head of mechanized excavator, foaming system, defoaming system. Because the present invention adopts foaming system and defoaming system to debug the foam machine, the coupling of foaming system and defoaming system can make the foam surround the cutting head of the fully mechanized excavator without a large amount of foam accumulation, and the cutting head Foam always surrounds the cutting head, safe and reliable,
[0011] The foaming system consists of a foam nozzle (1), a regulating valve (3), a foam liquid pipeline (18), a foamer (11), a foaming agent mixer (10), an adding pump (7), a foaming agent (8), It consists of a flow meter (4), a pressure gauge (5), a switch (6), a fully mechanized excavator air pressure device (14),...

The invention relates to a foam dust removing system during operation of an integrated excavator on an integrated excavating working face of a coal mine and aims to effectively solve the problem about dust flying during operation of the integrated excavator on the integrated excavating working face of the coal mine. The foam dust removing system is structurally composed of a foaming system and a defoaming system. The foam dust removing system is debugged by the aid of structures of the foaming system and the defoaming system, the foaming system and the defoaming system are coupled to enable foam to surround a cutting head rather than accumulate in mass, and the foam always surrounds the cutting head, so that security and reliability are achieved, and the foam dust removing system is of great significance in dust removing of the integrated excavating working face. The foam dust removing system is simple, novel and unique in structure and capable of preventing dust from flying and eliminating dust flying foundationally, is a great innovation for the dust removing industry of the integrated excavating working face of the coal mine, and has great social and economic benefits in promotion and application.
Description
technical field [0001] The invention relates to the field of coal mine safety, in particular to a dust removal system for a fully mechanized excavator in a coal mine fully mechanized excavation face. Background technique [0002] At present, the dust removal system of fully-mechanized excavation machines in coal mines in various countries uses press-in or exhaust ventilation for dilution. It is a kind of passive dilution of dust without dust removal, which only treats the symptoms but not the root cause. This method of diluting dust cannot eliminate dust in real time, and people can still inhale it into the body to cause harm. The fully mechanized excavation face of coal mines is in urgent need of a dust removal system that eliminates dust in real time. Contents of the invention [0003] In view of the above situation, the purpose of the present invention is to provide a real-time dust removal system for the fully-mechanized excavation machine of the coal mine fully-mecha...
