Description

Technical Field

[0001] This invention relates to the field of dust removal technology in mining, and in particular to a multifunctional dust removal device for mining. Background Technology

[0002] Dust control is a crucial aspect of ensuring operational safety and worker health during mining operations. Currently, most common mine dust control devices employ a single dust removal method, often focusing only on dust removal in a specific area, such as top spraying or bottom suction. This fails to achieve synergistic operation between top spraying and bottom suction, leading to secondary suspension of dust in the air, resulting in low dust removal efficiency. Furthermore, traditional filter cartridges tend to accumulate dust on their surfaces after prolonged use, increasing airflow resistance and reducing dust removal effectiveness. Cleaning often requires shutdown and disassembly, impacting continuous operation efficiency. The lack of a self-cleaning mechanism or incomplete cleaning leads to frequent equipment maintenance, short lifespan, and high operating costs. Summary of the Invention

[0003] The purpose of this invention is to provide a multifunctional dust removal device for mining operations, which aims to solve or improve at least one of the above-mentioned technical problems, realize the integration of dust removal, cleaning and collection, reduce manual intervention, and adapt to the harsh environment of mines.

[0004] To achieve the above objectives, the present invention provides the following solution: The present invention provides a multifunctional dust removal device for mining operations, comprising: The dust collection box is equipped with a dust inlet and a drain outlet, and the dust inlet is connected to a dust suction mechanism. A water tank is connected to the drain outlet via a water inlet pipe. The water tank is connected to a spraying mechanism, which is located above the dust collection mechanism. The filter cartridge is slidably installed inside the dust collection box by a lifting mechanism, and the filter cartridge is connected to the dust inlet; An adsorption ring is rotatably connected inside the dust collection box via a rotating mechanism. The adsorption ring is sleeved outside the filter cartridge. A communicating cavity is provided inside the adsorption ring. Multiple elastic suction heads are arranged circumferentially on the adsorption ring and communicate with the communicating cavity. The elastic suction heads abut against the side wall of the filter cartridge. A negative pressure collection mechanism is connected to the communicating cavity.

[0005] Optionally, the lifting mechanism includes: A waterproof motor is installed inside the dust collection box. The output shaft of the waterproof motor is connected to a ball screw, and a ball nut is driven and fitted on the ball screw. The ball nut is connected to the filter cartridge. A pair of guide rods are fixedly connected inside the dust collector and symmetrically located on both sides of the ball screw. Guide rings are slidably fitted on the guide rods, and the guide rings are connected to the filter cartridge.

[0006] Optionally, the rotating mechanism includes: The toothed ring is fixedly connected to the adsorption ring; The gear is coaxially and fixedly connected to the ball screw, and the gear meshes with the gear ring.

[0007] Optionally, a rotating frame is fixedly connected inside the dust collection box, and the rotating frame is rotatably connected to the adsorption ring through a sliding groove and a slider.

[0008] Optionally, the flexible suction head includes: A fixed tube is fixedly connected to the adsorption ring and communicates with the communicating cavity; a movable groove is provided on the side wall of the fixed tube.

[0014] The present invention discloses the following technical effects: This invention employs a spray mechanism positioned above the dust collection mechanism, forming a three-dimensional dust removal mode of spraying from above and suction from below. The spray mechanism atomizes water into ultrafine droplets of 1-100 micrometers. These droplets collide with dust particles in the air to form agglomerates, which then settle rapidly under gravity, effectively inhibiting dust diffusion and improving dust removal efficiency.

[0018] Existing Chinese patent CN109779676A discloses a multifunctional dust removal device for mining operations. Before use, the connections between devices must be checked to ensure they meet requirements. The dust pump rotates, drawing dust from the suction device into the dust removal device. The dust then enters the ventilation pipe through the air pump connection pipe and exits through the air outlet. Dust, slag, and other particles in the air settle in water. Once a certain amount has settled, the suction pump stops. At this point, motor A drives pulley A to rotate. Pulley A, via belt A, drives the rotating pulley, which in turn drives the internal rotating screw. This rotating screw restricts the rotation of the threaded ring by a movable slot, causing the threaded ring to move on the internal rotating screw. The threaded ring, through the connecting block, drives the external moving pipe upwards. The external moving pipe then... During the upward movement, the mudguard is pushed upward around the mudguard mounting axis, finally blocking the air outlet to prevent coal slurry from returning to the air pipe. When the external moving pipe rises to the limit block, the drive motor is then started. The drive motor drives the power shaft to rotate through the connecting shaft, which in turn drives the active helical gear. The active helical gear drives the lead screw to rotate around the lead screw fixing ring through the driven helical gear. Because the fixed square tube and the moving inner tube are in tandem, the mating threaded ring will move on the lead screw, which in turn drives the moving inner tube to move. The moving inner tube drives the scraper device to move downward and insert into the coal slurry. Then, the rotating power motor is started, which drives the rotating output pulley to rotate. The rotating output pulley drives the rotating large pulley to rotate through the transmission belt. The large pulley drives the concave wheel to rotate via a connecting shaft. Because the concave wheel cooperates with the slide rail, the left and right moving device moves on the slide rail. The slide rail then drives the scraper device to move and scrape off the coal slurry from the slurry mesh. The coal slurry falls down along the gap between the water tank and the shell. The stirring motor drives the agitator to rotate via a coupling, mixing the coal slurry evenly. The evenly mixed coal slurry falls into the circular pit. Then, the motor drives the output belt A to rotate via output pulley A. Output belt A drives the actuating pulley to rotate. The actuating pulley swings on the rotating connecting shaft via a actuating fork, thereby driving the adjusting rotating pulley to rotate. The adjusting rotating pulley drives the coal slurry ball discharge device to rotate via transmission belt A. When the circular pit rotates to the coal ball discharge outlet, the coal balls are discharged. The adjusting rotating pulley rotates one revolution per minute. The coal slurry ball-discharging device rotates twice. Because the adjusting pulley pauses after every one-sixth of a rotation, the rotating cylinder rotates one-third of a rotation and then pauses. This allows the coal slurry to fully fill the circular pit and also allows the coal balls in the lower pit to fall. When the coal balls fall from the coal slurry ball-discharging device onto the coal ball transmission device, the drive motor drives the drive pulley to rotate. The drive pulley, through the drive belt, drives the rotating pulley to rotate, which in turn drives the rotating roller of the entire coal ball transmission device to rotate. The rotating roller then propels the coal balls outwards. During this transmission process, the air inlet device blows purified air from the dust removal device into the air inlet pipe through the vent pipe, and then into the heating device mounting layer.The heating device heats the incoming air and then blows it out through the hot air outlet to dry the coal briquettes on the coal briquette transmission device. Because the device needs to move within the mine, the power motor drives the output pulley to rotate, which in turn drives the transmission pulley via a belt. The transmission pulley drives the rotating shaft to rotate, which in turn drives the driving wheel to rotate. The driving wheel, through the tracks, drives the driven wheel to rotate, thus causing the tracks to move relative to the ground, allowing the device to move.

[0019] An existing Chinese patent, CN210509268U, discloses a multi-functional dust removal device for mining operations. In use, the device is first moved to the area requiring dust collection. The vacuum cleaner is then turned on, drawing dust into the dust collection box through the duct. A first water pump is activated, spraying water onto the dust through nozzles, causing the dust to degrade and fall through a filter into a wastewater tank below. Wastewater is then discharged through a drain outlet. After dust collection is complete, a second water pump is activated, drawing water from the storage tank into a water spraying device. The water is then atomized and sprayed outwards through an atomizer. The spraying device can be adjusted in angle by raising and lowering the lower movable column within the support column, controlling the spray range and achieving a secondary dust removal effect, thus improving dust collection efficiency. This multi-functional dust removal device is used for dust removal during mining operations.

[0023] The spray mechanism is located above the dust collection mechanism, forming a three-dimensional dust removal mode of spraying from above and suctioning from below. The negative pressure collection mechanism achieves negative pressure adsorption through the rotation of the adsorption ring and the elasticity of the flexible suction head. As the filter cartridge slides, it continuously cleans the surface of the filter cartridge. It realizes an integrated design of dust removal, cleaning and collection, with a compact structure, suitable for the narrow space of mines, and improves the integration and reliability of the overall dust removal system.

[0024] In one embodiment of the present invention, the lifting mechanism includes: A waterproof motor 6 is installed inside the dust collection box 1.

[0025] The waterproof motor 6 drives the ball screw 7 to rotate.

A spring 19 is fixedly connected between the movable tube 18 and the movable groove 17.

[0031] The movable tube 18 supported by spring 19 is designed to give the suction head an adaptive clamping capability, keeping it in close contact with the surface of filter cartridge 3, ensuring the sealing and cleaning effect of negative pressure adsorption.

[0032] In one embodiment of the present invention, the negative pressure collection mechanism includes: Collection box 20 is located outside dust collection box 1; The negative pressure unit 21 has its discharge end connected to the collection box 20, and its adsorption end connected to the connecting cavity through the connecting pipe 22.

[0033] By combining the negative pressure unit 21 with the collection box 20, the dust can be collected and treated in a centralized manner, avoiding secondary dust generation, meeting environmental protection requirements, and facilitating subsequent cleaning and transportation.

[0034] Furthermore, the adsorption ring 4 is circumferentially slidably fitted with a connecting ring 30. The contact surface between the connecting ring 30 and the adsorption ring 5 is sealed by a sealing gasket. The connecting ring 30 has a connection port that is connected to the communicating cavity. The connection port is fixedly connected to and communicates with the connecting pipe 22. In this way, the adsorption ring 4 can rotate circumferentially along the connecting ring 30 when it rotates, avoiding interference from the communicating pipe 22. The connection port on the connecting ring 30 ensures the communication between the communicating cavity and the communicating pipe 22.

[0036] The corrugated expansion tube 23 has good extensibility and sealing performance, adapts to the positional changes during the lifting and lowering of the filter cartridge 3, and ensures the continuity and stability of the dust inlet channel.

[0037] In one embodiment of the present invention, the dust collection mechanism includes: Vacuum cleaner 24, the discharge end is connected to the dust inlet; The conical extension shroud 25 is connected to the suction end of the vacuum cleaner 24.

[0038] The suction generated by the vacuum cleaner 24 allows dust to enter the filter cartridge 3 through the dust inlet.
