Description

Technical Field

[0001] The utility model relates to the field of coal mine dust removal equipment, in particular to a water power dust collector. Background Art

[0002] Coal mine dust is one of the five major hazards in mines. In the process of coal production, most of the operating procedures can generate dust. In recent years, with the continuous improvement of the intensive production intensity and mechanization degree of coal mines, the amount of dust generated in coal mining faces has increased sharply. The dust concentration on the mining faces of most coal mines is high, even exceeding the national requirements for coal mine dust. Respiratory dust is extremely harmful to the health of workers. Long-term inhalation of respirable dust by workers can cause lung lesions and pneumoconiosis. The incidence of coal mine pneumoconiosis is extremely high, which brings great pain to coal miners and their families. For pneumoconiosis, the current medical level can only alleviate it, but cannot cure it. Long-term illness will make patients lose their ability to work. In addition, local dust accumulation is also prone to dust explosion accidents. The impact of coal dust and coal explosion is strong. In severe cases, it can cause a large number of casualties and cause extremely serious social impacts.

[0003] Traditional dust removal equipment usually uses dry dust removal or filtering dust removal, but these methods are not effective in dealing with high-concentration, large-area, and complex dust, and are large and bulky. Therefore, it has become a top priority to develop a new, convenient, efficient, and energy-saving dust removal equipment for mining. Utility Model Content

[0004] In response to the problems existing in the background technology, a water-powered dust collector is proposed, which uses the water pressure of the underground water as the power source to drive the fan blades to rotate. The wind sucks the dust into the shell and forms water mist particles at the same time, realizing the wind-water linkage dust reduction.

[0005] The utility model provides a water-powered dust collector, comprising a filter that uses underground water as a filtering object, a shell having one end for air intake and dust and the other end for water and dust discharge, and a dust removal component located in the shell, one end of which is connected to the filter and the other end of which uses underground water pressure as a power to generate airflow and water mist that act on dust.

[0006] Preferably, the dust removal assembly includes a sleeve connected to the water outlet end of the filter, a water outlet pipe penetrating through the sleeve, a fan blade arranged in the middle of the water outlet pipe, and a nozzle arranged at the end of the water outlet pipe.

[0007] Preferably, the water outlet pipe is rotatably connected to the sleeve; a water shaft connected to the water outlet pipe is arranged in the sleeve.

[0008] Preferably, the nozzle is a cross-shaped structure.

[0009] Preferably, the dust removal assembly also includes two groups of mounting frames; the two groups of mounting frames are fixedly connected to the inner wall of the shell, one group is rotatably connected to the water outlet pipe, and the other group is fixedly connected to the sleeve.

[0010] Preferably, the water inlet end of the filter is connected to the underground water pipe through pipe 1, and the water outlet end is connected to the sleeve through pipe 2, and a filter screen is arranged inside.

[0011] Preferably, it also includes a base, and the filter and the shell are arranged on the base.

[0012] Preferably, the side walls of the shell are rotatably connected to the mounting posts on the base, and protective nets are provided at both ends.

[0013] Compared with the prior art, the utility model has the following beneficial technical effects:

[0014] 1. The utility model adopts a filter as a pre-treatment to filter and clean the underground water, remove impurities such as solid particles with slightly larger diameters in the water flow, such as mud and rust, so that the water-powered dust collector will not block the nozzle due to the water flow itself. On the one hand, the probability of nozzle blockage is reduced, and the cost of manual maintenance and replacement is reduced. On the other hand, the use effect of the nozzle is greatly improved. The water mist is combined with coal dust to reduce the environmental dust concentration in places such as tunnels and working surfaces.

[0015] Second, the utility model uses the water pressure of underground water to drive the water shaft to rotate, which in turn drives the water outlet pipe to rotate, generates power, drives the fan blades to rotate, and the wind sucks the dust into the shell. On the other hand, the underground water uses its own water pressure to disperse and spray out through the nozzle to form water mist particles. The refined water mist effectively captures the dust suspended in the working environment, realizing the wind and water linkage dust reduction. At the same time, it reduces the amount of water mist required for dust reduction, improving the extremely humid mining environment.

[0016] 3. The utility model effectively reduces the complexity of equipment installation and is highly adaptable to various complex environments. The overall structure of the equipment is compact and light, which is convenient for disassembly and movement during actual operations, saving mining labor maintenance, device replacement and time costs.
