Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to an adjustable wet dust collector for mining. Background Art

[0002] A dust collector is a device that separates dust from flue gas. The performance of a dust collector is expressed by the amount of gas that can be processed, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price, operation and maintenance costs, service life, and difficulty of operation and management of the dust collector are also important factors to consider its performance. Dust removal in coal mines is extremely important. It is related to the health of the workers. Severe dust pollution will threaten underground production safety and cause serious accidents such as casualties. A large amount of dust will inevitably be generated during underground mining. In the existing technology, mining wet dust collectors are usually used for dust removal.

[0003] However, when some existing wet dust collectors for mining are performing dust removal operations, the dust particles in some mines are of different sizes in different working environments. The pore sizes of the filter plates of most wet dust collectors for mining are fixed. Large dust particles are easily blocked by equipment that can filter fine dust, and small dust particles are filtered by equipment that can filter larger dust. The dust filtering effect is poor, and the subsequent cleaning and maintenance are cumbersome. It is necessary to replace different types of equipment to collect and filter the dust in the mine, which is inconvenient for staff to use and has low work efficiency. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an adjustable wet dust collector for mining to solve the technical problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable wet dust collector for mining, comprising a dust collector and a first motor, wherein fixed plates are fixedly installed at both ends of the dust collector, an outer drum screen is movably installed on one side of the fixed plate, and a limiting hole is provided at one end of the outer drum screen, a transmission shaft is movably installed at the output end of the first motor, and a spiral plate is movably installed at one end of the transmission shaft, an inner drum screen is fixedly installed on the side of the spiral plate, and an insert block matching the limiting hole is fixedly installed at one end of the inner drum screen.

[0006] By adopting the above technical solution, the outer drum screen is driven by the meshing of the gear shaft and the toothed disc to slowly move for fine adjustment, thereby changing the size of the screen holes of the outer drum screen and the inner drum screen, and resetting the inner drum screen by the hydraulic rod so that the limit hole can re-limit the plug block, thereby increasing the applicability of the mining wet dust collector to different working environments, simplifying the operating steps, facilitating the later cleaning and maintenance of the equipment, and facilitating the use of the staff, thereby reducing the work intensity of the staff to a certain extent.

[0007] The utility model is further configured as follows: support legs are fixedly installed at the bottom of the dust collector, and the support legs are arranged in four groups; a dust collecting pipe is fixedly installed at one end of the dust collector, and a water pipe is fixedly installed at one side of the dust collecting pipe.

[0010] By adopting the above technical solution, by installing a nozzle, the nozzle sprays water mist into the inside of the device, which can help absorb and lock dust, dirt and tiny particles, making them easier to be sucked away by the vacuum cleaner. In addition, water can also reduce the flying of dust and reduce the concentration of particles in the air, thereby improving indoor air quality.

[0012] By adopting the above technical solution and providing an inclined chute, the filtered sludge impurities can be better concentrated and discharged from the sewage outlet due to the action of gravity and the limitation of the inclined surface of the inclined chute, making it convenient to collect and process the filtered impurities.

[0013] The utility model is further configured that a second motor is fixedly installed on one side of the dust collector, and a gear shaft is movably installed on the output end of the second motor, and sieve holes are provided on the surfaces of the outer drum screen, the inner drum screen and the filter plate.

[0014] By adopting the above technical solution, sieve holes are opened on the outer drum screen, the inner drum screen and the surface of the filter plate. The appropriate size of the sieve holes can improve the filtration efficiency, reduce blockage and filtration time, and the sieve holes can prevent excessively large particles from entering the interior of the equipment, avoiding damage or wear to the equipment and improving work efficiency.

[0015] The utility model is further configured that a toothed disc is fixedly mounted on one end of the outer drum screen, and the toothed disc and the gear shaft are meshingly connected.

[0016] By adopting the above technical solution, a filter plate is fixedly installed at one end of the dust collector, and is meshedly connected between the toothed disc and the gear shaft, thereby making the transmission mode more stable and the device structure more perfect.
