Embodiment Construction

[0011] An example of the present invention will be further described below in conjunction with accompanying drawing:

[0012] The adjustable foam injection device for preventing and controlling cutting dust of the present invention is mainly composed of a quick plug joint 1 , a control valve 2 , a foam delivery pipe 3 , an adjustment ring 4 , blades 5 and injection ports 6 . The quick plug-in joint 1 is set on the foam delivery pipe 3, and the outlet of the foam delivery pipe 3 is provided with a control valve 2. The inner diameter of the outlet of the foam delivery pipe 3 is a tapered inner diameter, and an adjustment ring 4 is set on the outer edge of the foam delivery pipe. Connected with the outer wall of the foam delivery pipe 3 through threads, the opening of the front end of the adjustment ring 4 is in the shape of a circular table; There is a gap between the annular injection ports 6, the gap of the annular injection ports 6 is adjustable, the position of the adjusting...

Abstract

The invention discloses an adjustable-type foam injection device for preventing cutting dust, which is composed of a quick connecting plug, a foam conveying tube, a control valve, an adjusting ring, a blade and injection orifices, wherein the quick connecting plug and the control valve are sequentially arranged at the front end of the foam conveying tube, the tail end of the foam conveying tube is connected with the adjusting ring, the blade is fixed in the adjusting ring, and a plurality of the injection orifices are formed at the end head of the blade. The flow of foams is adjusted via the control valve, and the injection angle of the foams is changed via the adjusting ring; a part of the foams is injected to the cutting part of mining machinery via the injection orifices under the drive of a pressure to form a conical foam cover for effectively covering and wrapping a cutting dust source, thus preventing the generated dust from escaping outwards while reducing the generation of dust; and the other part of the foams is injected via the injection orifices to rapidly capture the floating dust closed in the foam cover, thus realizing efficient suppression and sedimentation on the cutting part of the mining machinery. The device is good in dust capture effect, simple in structure, convenient to adjust, no moving parts in the interior, high in reliability, and wide in practicability.

Description

technical field [0001] The invention relates to a spraying device, in particular to an adjustable foam spraying device for preventing and controlling cutting dust. Background technique [0002] More than 80% of the dust in the underground coal mine comes from the mining face, and the cutting of coal and rock mass by mining machinery is the most important dust-producing process in the working face, and the floating dust generated by it accounts for more than 90% of the total dust production in the working face. Therefore, taking effective measures to prevent and control cutting dust is of great significance to protect the health of coal mining workers and prevent coal dust explosions. Compared with conventional dust control technology, foam dust suppression has the advantages of high dust reduction efficiency, less water consumption, and less impact on the sight of mining drivers. It is an emerging technology with important application prospects. It has been tested and verifi...
