Description

Technical Field

[0001] The utility model relates to the technical field of underground mines, in particular to air supply equipment for underground mines. Background Art

[0002] A mine is a general term for the shafts, chambers, equipment, ground buildings and structures that form an underground coal mine production system. Sometimes, inclined shafts, vertical shafts, horizontal shafts, etc. in underground mine development are also called mines. During the mine production process, a large number of shafts and tunnels are excavated to prepare new levels, new mining areas and mining faces. When excavating the tunnels, in order to supply enough oxygen to the workers and dilute the gas in the excavation working face, air supply equipment must be used to supply air to the excavation working face.

[0003] The utility model patent application document with publication number "CN221053954U" discloses a mine exhaust ventilation equipment, which is mainly composed of a ventilation cylinder shell, a cross support frame, a powerful motor, fan blades, a heating mesh plate, an adsorption plate, a filter plate and a sponge plate. This technical solution is provided with a heating mesh plate, a powerful motor and fan blades. Through the cooperation of the adsorption plate, the sponge plate and the filter plate, the powerful motor is used to drive the fan blades to rotate, so that the air generates airflow that passes through the adsorption plate, the filter plate and the sponge plate in turn, thereby completing the adsorption of dust, purification of air and adsorption of moisture in the air in turn. The purified airflow will then pass through the heating mesh plate under the rotation of the powerful motor and the fan blades.

[0004] The mine exhaust ventilation equipment disclosed in the above-mentioned document has the following defects: after long-term use, the outer surfaces of the adsorption plate, filter plate and sponge plate of the exhaust ventilation equipment will absorb a large amount of dust and impurities, thereby causing the air circulation to deteriorate. Since the adsorption plate, filter plate and sponge plate are fixedly connected to the inside of the ventilation shell, it is inconvenient to clean and replace the adsorption plate, filter plate and sponge plate, affecting the use of the equipment.

[0005] It can be seen from this that the existing mine exhaust ventilation equipment is not convenient for replacing adsorption plates, filter plates and sponge plates. It is necessary to improve the existing deficiencies and provide air supply equipment for underground mines. Utility Model Content

A support plate 101 is provided inside the ventilation shell 1, and a connecting ring 102 is provided at one end of the support plate 101 away from the ventilation shell 1. A motor 6 is installed inside the connecting ring 102, and a fan blade 7 is installed at the output end of the motor 6. A first connecting plate 202 is provided on the outer surface of the cover plate 2, and a second connecting plate 103 is provided on the outer surface of the ventilation shell 1. The outer surfaces of the first connecting plate 202 and the second connecting plate 103 are both provided with mounting holes 8, and a fixing component 9 is provided inside the mounting hole 8.

[0027] A support frame 104 is provided on the outer surface of the ventilation housing 1;

[0028] A base 10 is provided at one end of the support frame 104, and a ventilation housing 1 is mounted on the upper surface of the base 10;

[0029] A connecting flange 105 is provided at one end of the ventilation housing 1 away from the fan blades 7;

[0030] The fixing assembly 9 includes a connecting block 901, which is installed inside the mounting hole 8. A sliding groove 902 is provided on the upper surface of the connecting block 901. A connecting rod 903 is installed inside the sliding groove 902. A slider 904 is slidably connected to the outer surface of the connecting rod 903. The sliders 904 are set in two and are symmetrically distributed. A spring 905 is installed between the two sliders 904. The spring 905 is sleeved on the outer surface of the connecting rod 903. An abutment block 906 is provided at one end of the slider 904. One end of the abutment block 906 passes through the connecting block 901 and extends outward. The outer surface of the abutment block 906 abuts against the outer surface of the second connecting plate 103.

[0031] A protective shell 907 is mounted on the inner surface of the slide 902, and a baffle 908 is provided on the upper surface of the slider 904;

[0032] By squeezing the two baffles 908 inward, the two baffles 908 drive the slider 904 to move toward the adjacent end on the connecting rod 903, and at the same time, the abutment block 906 gradually retracts into the interior of the slide groove 902. When the outer surface of the abutment block 906 is flush with the outer surface of the connecting block 901, the baffle 908 can be pulled upward to disengage the connecting block 901 from the mounting hole 8, thereby canceling the fixed installation of the ventilation shell 1 and the cover plate 2, thereby facilitating the cleaning and replacement of the adsorption plate 3, filter plate 4 and sponge plate 5 in the slot 201, thereby achieving better practical effect.

[0033] When in use, first place the air supply equipment at the place to be worked, fix the connecting flange 105 to the external ventilation duct, start the motor 6, so that the output end of the motor 6 drives the fan blades 7 to rotate at high speed, so that the air flow generated by the air is sucked from the outside to the inside of the ventilation shell 1, and then the air flow passes through the adsorption plate 3, the filter plate 4 and the sponge plate 5 in turn. The air flow will be adsorbed dust, purified air and moisture contained in the adsorbed air flow in turn, and discharged into the interior of the mine through the ventilation duct. When the adsorption plate 3, the filter plate 4 and the sponge plate 5 need to be replaced, first remove the protective shell 907 from the inside of the slide 902, and by squeezing the two baffles 908 inward, the two baffles 908 drive the slider 904 to move to the near end on the connecting rod 903, and at the same time, the abutment block 906 gradually retracts into the inside of the slide 902. When the outer surface of the abutment block 906 is flush with the outer surface of the connecting block 901, the baffle 908 can be pulled upward to disengage the connecting block 901 from the mounting hole 8, so that the ventilation shell 1 and the cover plate 2 are fixedly installed, thereby facilitating the cleaning and replacement of the adsorption plate 3, the filter plate 4 and the sponge plate 5 in the card slot 201. After replacement, the cover plate 2 and the ventilation housing 1 are closed so that the mounting holes 8 of the first connecting plate 202 and the second connecting plate 103 are aligned. By squeezing the two baffles 908 inward, the two baffles 908 drive the slider 904 to move toward the adjacent end on the connecting rod 903, the spring 905 gradually contracts, and the abutment block 906 gradually retracts into the slide groove 902. When the outer surface of the abutment block 906 is flush with the outer surface of the connecting block 901, the connecting block 901 can be installed back into the mounting hole 8, and when the lower surface of the connecting block 901 abuts against the upper surface of the first connecting plate 202, the force on the baffle 908 can be cancelled, so that the spring 905 pushes the slider 904 to reset, so that the abutment block 906 extends from the inside of the slide groove 902 and abuts against the outer surface of the second connecting plate 103, thereby completing the fixed installation of the ventilation shell 1 and the cover plate 2.
