Technical Field

[0001] The invention relates to the field of mining, in particular to a multifunctional dust removal device for mine construction. Background Art

[0002] In recent years, with the advancement of science and technology, the degree of mechanized mining in mines has been increasing. While the production of mines has been greatly improved, the amount of dust generated during mining operations has also increased sharply. Especially in the process of mining, rock drilling, blasting, transportation, etc., the concentration of dust in mine production has become more and more serious, which not only reduces the visibility of the work site, but also has a great impact on production safety to a certain extent. The large amount of dust problems caused by this have become the key to threatening the safety of mine operations and the life and health of employees. In order to improve the working environment of mines and ensure production safety, most mines will adopt different dust removal and ventilation measures and a series of dust reduction methods to control dust according to actual conditions.

[0003] The dust suppression device can remove dust very well. The general dust removal device has a relatively single function and can only remove dust by spraying or ventilation. At this time, different dust removal devices need to be equipped during mining to adapt to various dust removal situations, which is more troublesome.

[0004] In summary, the present invention provides a multifunctional dust removal device for mine construction to solve the above problems. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a multifunctional dust removal device for mine construction to solve the problems that the general dust removal devices in the prior art have relatively single functions and low dust removal efficiency.

[0006] The multifunctional dust removal device for mine construction described in the present invention comprises a foam dust reduction device and a dust suction device. The foam dust reduction device comprises a water pump and a foaming agent storage tank, which are respectively located on the left and right sides of a mixer, and the two sides are connected by a conveying pipe. The upper conveying pipe connects the mixer to the outside. The foaming net is located at the connection between the mixer and the conveying pipe. The foam generated by the foaming net is conveyed to the nozzle by the conveying pipe. The nozzle is located on the upper right side of the box body, and the rubber hose connects the conveying pipe and the nozzle. The dust suction device comprises a dust collecting box, which is located on the left side of the box body. An air inlet and a fan are installed above the dust collecting box, and a water tank is provided below as a deposition component. A ventilation duct connects the air inlet and the water tank. The water tank and the water pump are connected by a water supply pipe for convenient water supply. Control valves are installed below and on the right side of the water tank. A motor is installed on the left side of the box body.

[0007] Preferably, the water pump is connected to a delivery pipeline on both the left and right sides, which can supply water to the water tank and the mixer; Preferably, a filter screen is installed at each of the air inlet and the air outlet to further enhance the dust removal effect; Preferably, the foam delivery pipeline is connected to the foam nozzle by a rubber hose, which has strong chemical resistance and also increases the dust reduction distance of the foam. BRIEF DESCRIPTION OF THE DRAWINGS

It is a schematic diagram of the structure of the present invention; in the figure: 1. water pump, 2. mixer, 3. foaming agent storage tank, 4. motor, 5. foaming net, 6. nozzle, 7. hose, 8. conveying pipeline, 9. dust removal box, 10. water tank, 11. water control valve, 12. ventilation duct, 13. fan, 14. filter, 15. air inlet, 16. air outlet, 17. box body. DETAILED DESCRIPTION

[0009] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the structures related to the present invention. When the present invention is in use, the foam dust reduction function can be used for large-area dust. The water in the water pump and the foaming agent in the foaming agent storage tank are mixed in a mixer, and foam is generated through the action of the foaming net. The foam is transported to the nozzle through a conveying pipeline. At the same time, the opening and closing of the nozzle and the nozzle area are manually controlled to spray the foam from the nozzle, so as to perform foam dust reduction treatment on the large amount of foam generated on the large-area working surface in the mine tunnel; For small-area fine dust particles, the dust suction function can be used to reduce dust. The dust suction device is controlled and the fan is used to suck air mixed with fine dust particles into the air inlet. After passing through the air inlet, it is first filtered by the filter and then introduced into the water tank through the ventilation duct for secondary dust reduction. When the water in the water tank is changed, the water can be discharged through the water control valve below and then injected into the water tank by the water pump. The filtered air is discharged from the air outlet under the action of the outlet fan and is dust-removed through the filter again before being discharged from the air outlet, so as to achieve the purpose of efficient dust removal of fine dust particles.
