Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal equipment, in particular to dust removal equipment for underground mines. Background Art

[0002] Dust removal equipment refers to equipment that separates dust from flue gas. It is also called a dust collector or dust removal equipment. Dust removal equipment utilizes underground dust removal water pipes and compressed air pipelines, adds certain additives to the water, introduces wind pressure, and completes a series of process flows through special equipment to generate foam, which is sprayed onto the dust source through a distributor and nozzle bracket assembly. Overview of the development of dust removal technology The application and development of dust removal technology is closely related to my country's industrialization process. Dust removal technologies generally include mechanical dust removal, wet dust removal, electrostatic dust removal and bag dust removal.

[0003] For example, a Chinese patent with publication number CN211397638U discloses a mine dust removal device. The patent passes the ventilation pipe into the hole, starts the driving assembly, and the controller controls the extension and retraction of the telescopic rod. The telescopic rod drives the first support assembly to move, so that the opening area adjustable mechanism on the surface of the ventilation pipe is unfolded, and the dust shield cloth on the first support rod will cover the hole according to the shape and size of the hole, so that dust will not float out from the edge of the ventilation pipe, and the induced draft fan is started to draw the dust inside out of the hole.

[0004] The above patent has the following problems:

[0005] This patent has some shortcomings when in use, such as: the dust sucked out by the induced draft fan is blocked by the dust shield cloth, and then the dust will accumulate on the surface of the dust shield cloth. When the dust shield cloth is blocked by dust, the staff may need to clean the dust on the surface of the dust shield cloth. When the dust leaves the surface of the dust shield cloth, the dust may be in a loose state, and then the scattered dust may drift into the air, causing dust pollution, which may affect the use effect of the dust removal equipment.

[0006] In view of this, we propose a dust removal equipment for underground mines. Utility Model Content

[0007] The purpose of the utility model is to provide a dust removal device for underground mines to solve the problems raised in the above background technology.

[0008] In view of this, the utility model provides a dust removal device for underground mines, comprising: a mounting plate, a dust removal box is fixedly mounted on the top surface of the mounting plate, a water storage tank is fixedly mounted on the top surface of the mounting plate, a circular through hole is opened on the top surface of the dust removal box, and a positioning ring is fixedly sleeved on the inner circular wall surface of the circular through hole;

[0009] Two exhaust holes, the two exhaust holes are respectively opened on both sides of the dust removal box, the insides of the two exhaust holes are fixedly sleeved with exhaust fans, the inner top surface of the dust removal box is fixedly installed with a support frame, and the interior of the positioning ring is provided with a dust-proof cloth bag;

[0010] A water storage tank, the water storage tank is fixedly mounted on the top surface of the dust removal box, a plurality of water mist nozzles are fixedly mounted on the top surface of the water storage tank, a water inlet pipe is fixedly mounted on the top surface of the water storage tank, a submersible pump is fixedly mounted on the inner bottom surface of the water storage tank, a connecting hole is opened on the top surface of the water storage tank, a connecting pipe is fixedly sleeved on the inner circular wall surface of the connecting hole, the connecting pipe is fixedly sleeved with the water outlet of the submersible pump, and one end of the connecting pipe is fixedly mounted on the water storage tank;

[0011] A limiting component is arranged on the top surface of the positioning ring and is used to limit and fix the dust bag.

[0012] In this technical solution, the staff adds water to the interior of the water storage tank through the water inlet pipe, and then the staff passes the dust-proof bag through the positioning ring and inserts it into the interior of the supporting frame. At this time, the staff uses two exhaust fans, and then the two exhaust fans will extract the air inside the dust removal box to the outside. Then, since the air inside the dust removal box is extracted, the air pressure in the dust removal box is lower than the outside air pressure. At this time, the outside air will enter the interior of the dust removal box under the action of atmospheric pressure, and then the dust-proof bag will block the dust in the air. In this process, the staff uses a submersible pump, and then the submersible pump will pump the water inside the water storage tank into the water storage tank through the connecting pipe. The dust collector is equipped with a water mist nozzle and a water mist nozzle. At this time, the external water mist will enter the dust removal box together with the air, and then the dust in the air will be adsorbed by the water mist and enter the dust barrier bag. When there is a lot of dust inside the dust barrier bag, the staff will remove the dust barrier bag and clean the dust. In this process, the dust is in a moist state due to the contact with the water mist. In the subsequent dust treatment process, the moist dust will be in the form of accumulation and agglomeration, thereby avoiding the phenomenon of secondary dusting during cleaning. The dust inside the mine is cleaned and the secondary dusting is prevented.

[0013] In the above technical solution, further, the limit assembly includes:

[0014] A pressure ring, wherein the pressure ring is arranged on the top surface of the positioning ring, and a plurality of mounting grooves are opened on the top surface of the positioning ring, and a plurality of connecting columns are slidably connected inside the plurality of mounting grooves, and a plurality of connecting columns are movably sleeved with springs on the outer circular walls, and a plurality of fixing rings are fixedly sleeved on the inner circular walls of the plurality of mounting grooves, and the inner circular walls of the plurality of fixing rings are respectively slidably connected with a plurality of connecting columns, and the bottom surface of the pressure ring is fixedly mounted on the connecting columns.

[0015] In the present technical solution, after the staff puts the dust bag into the interior of the supporting frame, the staff pulls the pressure ring, and the movement of the pressure ring will drive the movement of multiple connecting columns and squeeze the multiple springs. Then the staff places the open edge of the dust bag between the positioning ring and the pressure ring. At this time, the staff releases the pressure ring, and the rebound force of the multiple springs will drive the pressure ring to reset, and then the pressure ring will squeeze the dust bag, thereby achieving the effect of facilitating the limiting and fixing of the dust bag.

[0016] In the above technical solution, further, a collecting box is fixedly installed on the inner bottom surface of the dust removal box, a collecting bucket is fixedly installed on the top surface of the collecting box, the collecting bucket corresponds to the position of the supporting frame, a drain pipe mounting plate is fixedly installed on one side of the collecting box, and the drain pipe runs through the dust removal box.

[0019] In this technical solution, it is convenient for staff to know the water level inside the water tank.

[0020] In the above technical solution, further, mesh covers are fixedly installed on both sides of the exhaust hole, and the positions of the two mesh covers correspond to the positions of the two exhaust holes respectively.

[0025] The dust removal equipment used in the underground mine adds water into the water tank through the water inlet pipe, and the dust bag is inserted into the inside of the supporting frame. Two exhaust fans draw the air inside the dust removal box to the outside, and then the outside air will enter the inside of the dust removal box under the action of atmospheric pressure, and then the dust bag will block the dust in the air. At this time, a submersible pump is used to pump the water inside the water tank into the water tank through a connecting pipe, and spray it out through multiple water mist nozzles. Then, the dust in the air will be adsorbed by the water mist and then enter the inside of the dust bag.
