Abstract

The invention relates to a spraying and dust settling device for a coal mine heading machine. The spraying and dust settling device comprises a case arranged on a heading machine body, a spraying cylinder arranged on the case and an air inlet pipe arranged in the middle of the spraying cylinder and communicated with the spraying cylinder. Two air blowers are fixed in the spraying cylinder and arepositioned on the two sides of the air inlet pipe correspondingly; and a water suction sleeve is arranged in the air inlet pipe, the outer side wall of the water suction sleeve is fixed to the inner side wall of the air inlet pipe, and the diameter of the inner wall of the water suction sleeve is gradually increased and then gradually decreased in the axis direction of the water suction sleeve. Awater supply tank is further arranged at the top of the spraying cylinder, water needed for atomizing is arranged in the water supply tank, and a connecting pipe is arranged between the water supply tank and the air inlet pipe; one end of the connecting pipe is connected with the bottom of the water supply tank and communicates with the interior of the water supply tank, the other end of the connecting pipe communicates with the inner side wall of the water suction sleeve, and the communicating position of the connecting pipe and the water suction sleeve is arranged at the smallest-inner-diameter position of the inner wall of the water suction sleeve. The spraying and dust settling device has a good spraying effect and is suitable for the severe working environment of the heading machine.

Description

technical field [0001] The invention relates to the technical field of spray dust suppression, in particular to a spray dust suppression device for a coal mine roadheader. Background technique [0002] Spray dust reduction is a new type of dust reduction technology. Its principle is to use the particles produced by spray. Because of its extremely small surface tension, it is basically zero. When sprayed into the air, it can quickly absorb dust particles of various sizes in the air and form an effective control system. dust. It has a good effect on dust control and dust reduction in large open areas. At the same time, this effect is completely an atomization effect, which will never produce water droplets and humidity. It is especially suitable for wide application in foundries, textile factories, food factories, printing factories, airports, playgrounds, pedestrian streets, etc., and the cost is low and the effect is obvious. Dust damage is one of the five common disaster...
