An underground roadway spray dust suppression device

Abstract

The invention discloses a spraying dust fall device for an underground roadway in order to improve the situation. According to the spraying dust fall device for the roadway, after spraying dust fall,a mixture generated by water and dust particles is extracted, and dust in the extracted mixture is filtered away through multi-stage filter. The spraying dust fall device is characterized in that a fixed plate is placed in a main body box, the main body box is internally divided into a collecting cavity and a gas suction cavity, and the gas suction cavity is located on the upper portion of the collecting cavity; the right end of the fixed plate is inclined upwards; a plurality of filter plates are placed on the fixed plate, and the hole diameters of the multiple filter plates are decreased gradually from left to right; a through hole is formed in the right side of the main body box and communicates with the collecting cavity; one end of a water pumping pipe is placed on the right side of the main body box and corresponds to the through hole in the right side of the main body box; a strip-shaped groove is formed in the upper side of the main body box and is close to the left side of themain body box; and a gas collecting box is placed on the upper side of the main body box and communicates with the gas suction cavity through the strip-shaped groove in the upper side of the main body box.

Description

technical field [0001] The invention relates to an underground roadway spray dust suppression device, which relates to a coal mine underground dust suppression device for spraying roadways and belongs to the field of mining equipment. In particular, it relates to a roadway spray dust suppression device capable of pumping the mixture of water and dust particles after spray dust suppression, and filtering the dust in the pumped mixture through multi-stage filtration. Background technique [0002] At present, in the field of coal mines, during mining operations, the dust content in the air in areas such as roadways and mining faces is relatively large, and inhalation into the human body is extremely harmful to operators, and because of safety hazards such as explosions, spray dust is usually used for coal mine dust. The most commonly used spray dust suppression equipment is to spray water mist to reduce dust in areas with a lot of dust. The water mist is mixed with dust particl...

Problems solved by technology

[0002] At present, in the field of coal mines, during mining operations, the dust content in the air in areas such as roadways and mining faces is relatively large, and inhalation into the human body is extremely harmful to operators, and because of safety hazards such as explosions, spray dust is usually used for coal mine dust. The most commonly used spray dust suppression equipment is to spray water mist to reduce dust in areas with a lot of dust. The water mist is mixed with dust particles and the mass becomes larger and settles. Make the surface of the dust fall area adhere, destroy the working environment, easily cause the workers to slip and fall, and pollute the equipment. When the ventilation equipment is used for pumping, the mixture will be adsorbed to the pipes and blades, making it difficult to clean up. Long-term pumping will easily block the pipes , the existing dust suppression equipment, due to the high dust concentration in a short period of time when the coal mine is mining in the mining roadway, the dust suppression efficiency of the spray is poor, and the dust suppression device in the existing dust collection method does not consider the coal mine dust. Concentration problem, direct extraction of dust, the effect is even worse, and will face more serious blockage problems;

[0003] Publication number CN205135694U discloses an automatic dust suppression spraying device for coal mine transportation, including a spraying device, a control device and a water pump. The water pump is provided with a water inlet pipe and a water spray pipe. The device includes a rotary valve head, a wide-mouth spray head, a multi-way valve and a rotary spray head group. The valve is equipped with a rotating nozzle group. When using this device for dust reduction treatment, the mixed liquid falling on the ground will make the working environment worse, affect normal production, and the use effect is not good
