Problems solved by technology

At present, the dust removal devices for fully mechanized excavation working faces produced in the domestic market can only be used in low-gas mines. It is difficult to realize the dust treatment of fully mechanized excavation work in high and sudden mines, and it will also cause gas accidents; in addition, the nozzles of fully mechanized excavators are easy to block. , poor spray effect

Abstract

The invention discloses a strong and highly effective extravasation automatic liquid feeding device for a fully mechanized coal mining machine. The device consists of a water supply joint, an air supply joint, a water connecting pipe, an air connecting pipe, a dustfall agent box, a dustfall agent inlet, a flow meter, an observation hole, a dustfall agent suction pipe, a pressure water cavity, negative pressure ejectors, mixers and mixer outlets. The device is characterized in that the water connecting pipe is connected with the water supply joint and communicated with right lower parts of thethree mixers; the air connecting pipe, which is connected with the air supply joint and enters the three mixers from the bottom of the three mixers, is communicated with the three mixer outlets so asto form three negative pressure ejectors; one end of the dustfall agent suction pipe is connected with the flow meter, while the other end is communicated with the three negative pressure ejectors; and the dustfall agent suction pipe is inserted into the dustfall agent box through the dustfall agent inlet. The device has the advantages that own water source of a mine is used, the pressure air is dynamic force, good cooperation between the pressure air and dustfall water is realized, and dust on the working surface of the fully mechanized coal mining machine is clogged comprehensively. A spraying device is not clogged easily, spraying dustfall effect is good, the work production efficiency is greatly improved, the total dustfall rate can reach more than 95 percent, and the occurrence of lung diseases of coal mine workers is avoided. Meanwhile, gas accidents can be prevented.

Description

1. Technical field [0001] The invention relates to an external spray liquid adding device of a fully mechanized excavator in a coal mine, in particular to an external spray automatic liquid add device of a fully mechanized excavator. 2. Background technology [0002] At present, in coal mine production, dust is still one of the main problems. High concentration of dust not only poses a serious threat to coal mine safety, but also respirable dust is the direct cause of inducing pneumoconiosis among workers. Therefore, reducing dust concentration, especially Reducing the concentration of respirable dust is very necessary and also a major technical problem. In recent years, with the continuous improvement of the degree of mechanization of coal mines, the problem of dust in the fully mechanized excavation face has become a key issue that seriously restricts the improvement of the mechanization of fully mechanized excavators. At present, the dust removal devices for fully mechan...
