Spray dust suppression device for coal mine roadheader

Abstract

The invention relates to a spray dust suppression device for a coal mine roadheader, which comprises a machine case arranged on the body of the roadheader, a spray canister arranged on the chassis, and an air inlet pipe arranged in the middle of the spray canister and communicated with the spray canister; There are two blowers, and the two blowers are respectively located on both sides of the air inlet pipe; the air inlet pipe is provided with a water-absorbing jacket, the outer wall of the water-absorbing jacket is fixed to the inner wall of the air inlet pipe, and the diameter of the inner wall of the water-absorbing jacket is along its The direction of its own axis gradually becomes larger and then gradually smaller; there is also a water supply tank on the top of the spray tube, and the water supply tank is provided with the water required for fogging, and there is a connecting pipe between the water supply tank and the air inlet pipe; one end of the connecting pipe It is connected to the bottom of the water supply tank and communicates with the inside of the water supply tank. The other end of the connecting pipe communicates with the inner wall of the water-absorbing jacket, and the connection between the connecting pipe and the water-absorbing jacket is set at the inner diameter of the inner wall of the water-absorbing jacket. The invention has good spraying effect and is suitable for the harsh working environment of the roadheader.

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...
