Description

Technical Field

[0001] This utility model belongs to the field of mining engineering technology, and specifically relates to a ventilation and dust removal device for mining. Background Technology

[0002] In underground mining operations, dust pollution is a core problem that has long plagued the industry’s safety and efficiency. During the mining process, the shock waves generated by blasting operations will crush rocks into micron-sized particles. The operation of mechanical excavation equipment such as tunneling machines and coal mining machines will further aggravate the spread of dust. The bumps and loading and unloading operations in the ore transportation process will also cause secondary dust. Dust removal equipment is usually needed to suppress dust during the mining process.

[0003] However, current dust removal equipment typically uses the rotation of fan blades to generate suction, drawing dust into the equipment for processing. But the fan blades come into contact with dust during operation, causing dust to accumulate on the surface of the blades, which can affect their performance. Regular cleaning is usually required. Since the fan blades are usually installed inside the casing, disassembly is required for cleaning, which adds to the inconvenience of the cleaning process. Therefore, the applicant proposes a ventilation and dust removal device for mining to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a ventilation and dust removal device for mining, which can completely expose the fan blades through a simple operation method, allowing personnel to easily clean the dust accumulated on the surface of the fan blades without the need for complicated operations such as disassembly, thus bringing more convenience to the cleaning of the fan blades.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0030] Example 1:

[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a ventilation and dust removal device for mining includes:

[0032] Dust collection mechanism 1 and dust collection mechanism 2 assembled on one side of dust collection mechanism 1;

[0033] The dust suppression mechanism 1 includes a base 14, a dust suppression cylinder 11 is fixedly installed on the top of the base 14, an annular pipe 111 is fixedly installed on the inner wall of the dust suppression cylinder 11, and spray nozzles 112 are evenly distributed on the annular pipe 111.

[0034] The dust collection mechanism 2 includes a dust collection cylinder 21 connected to one side of the dust collection cylinder 11. A rotating rod 26 is rotatably installed inside the dust collection cylinder 21. A fan blade 27 is fixedly installed at one end of the rotating rod 26. A movable cylinder 22 is slidably installed around the dust collection cylinder 21. The movable cylinder 22 is wrapped around the fan blade 27. A thrust spring 23 is fixedly installed between the movable cylinder 22 and the dust collection cylinder 21.

[0035] As can be seen from the above, when using this device, it is moved to a suitable position in the mining area. By driving the fan blade 27 to rotate, a suction effect can be generated, which can easily suck the dust in the mining area into the dust collection cylinder 21 along with the airflow. The dust can be transported into the dust collection cylinder 11. By supplying water to the annular pipe 111, the dust in the airflow can be sprayed and the dust can be reduced by the spray head 112. The dust-reduced air is then discharged with the airflow, which is convenient for ventilation of the mining area.

[0036] When cleaning the fan blades 27 is required, the movable cylinder 22 is pushed to slide along the outer edge of the vacuum cleaner cylinder 21, locking the movable cylinder 22 around the vacuum cleaner cylinder 21. This allows the fan blades 27 to be completely exposed, making it easier for personnel to clean the dust accumulated on the surface of the fan blades 27 without the need for complicated operations such as disassembly. This greatly facilitates the cleaning of the fan blades 27. After cleaning the fan blades 27, by releasing the lock on the movable cylinder 22, the push spring 23 can push the movable cylinder 22 to move and reset, allowing the movable cylinder 22 to wrap around the fan blades 27 again for protection, thus improving the usage effect.

[0037] Depend on Figure 3 It can be seen that a water storage tank 18 is fixedly installed on the top of the base 14, and a water inlet 19 is opened on the top of the water storage tank 18. A caster wheel 15 is fixedly installed on the bottom of the base 14.

[0038] As can be seen from the above, water can be easily injected into the water storage tank 18 through the water inlet 19 for storage, and the base 14 can be moved by the rolling action of the moving wheels 15, so that the device can be easily moved to a suitable position for dust removal operation.

[0039] For details, please refer to Figure 3 As shown, a water pump 16 is connected to one side of the water storage tank 18, and a delivery pipe 17 is connected between the water pump 16 and the annular pipe 111.

[0040] As can be seen from the above, the water pump 16 can draw water from the water storage tank 18 and transport it to the annular pipe 111 through the delivery pipe 17, so that the water can be easily sprayed out through the spray head 112 to suppress dust.

[0041] For details, please refer to Figure 4 As shown, the bottom of the dust collection cylinder 11 is connected to a collection box 12, and the bottom of the collection box 12 is connected to a drain pipe 13.

[0042] As can be seen from the above, the wastewater generated during dust suppression by spraying can flow into the collection box 12, and the wastewater can be conveniently discharged to a suitable area using the sewage pipe 13 to avoid pollution to the surrounding environment.

[0043] Example 2:

[0044] refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 As shown, a dust supply pipe 110 connects the dust collection cylinder 11 and the dust collection cylinder 21. The dust collection cylinder 21 and the movable cylinder 22 are slidably installed through a sliding groove 210. A handle 24 is fixedly installed on the outer wall of the movable cylinder 22.

[0045] As can be seen from the above, the dust sucked in by the dust collection tube 21 can be guided into the dust suppression tube 11 for spraying and dust suppression through the dust delivery tube 110. The movable tube 22 can be slidable through the slide groove 210 to prevent the movable tube 22 from rotating or falling off. The movable tube 22 can be easily pushed to the outside of the dust collection tube 21 by the handle 24, which is convenient for cleaning the fan blade 27.

[0046] refer to Figure 6 As shown, a motor 25 is fixedly installed on one side of the vacuum cleaner 21, and the output shaft of the motor 25 is fixedly connected to the rotating rod 26.

[0047] As can be seen from the above, the motor 25 can provide power to the rotating rod 26, which can drive the rotating rod 26 to rotate. The rotation of the rotating rod 26 can synchronously drive the fan blade 27 to rotate, and the fan blade 27 can conveniently suck dust in the surrounding air into the dust collection cylinder 21.

[0048] refer to Figure 7 As shown, a locking frame 28 is hinged to the top of the vacuum cleaner cylinder 21, and a locking post 29 that engages with the locking frame 28 is fixedly installed on the top of the movable cylinder 22.

[0049] As can be seen from the above, when the movable cylinder 22 is moved to the periphery of the vacuum cleaner cylinder 21, the locking pin 29 can be moved to the bottom of the locking frame 28. Utilizing the gravity of the locking frame 28, the locking frame 28 can engage and limit the locking pin 29, preventing the movable cylinder 22 from moving. After cleaning the fan blade 27, it is only necessary to operate the locking frame 28 to flip upward and separate it from the locking pin 29, which allows the movable cylinder 22 to automatically reset and wrap and protect the fan blade 27, effectively improving the usage effect.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
