Description

Technical Field

[0001] This utility model relates to the field of dust removal technology in mining, specifically to an electromagnetic braking dust removal device for mining. Background Technology

[0002] Mining dust is an unavoidable byproduct of mining operations, primarily composed of ore particles and other powdery materials. This dust is generated during mining and subsequent processing. A complete mining processing line involves processes such as crushing, screening, grinding, transportation, and collection. Each process, accompanied by the breaking and movement of the ore, gradually separates fine particles, generating increasing amounts of dust.

[0003] The generation of mining dust poses the following hazards:

[0004] (1) Pollution of the environment and harm to human health: Dust pollution reduces the air quality of the work area and its surrounding environment. Long-term inhalation of dust can lead to occupational diseases such as pneumoconiosis.

[0005] (2) Causing explosions and fires: Some mineral dust (such as coal dust and sulfur dust) can burn or explode under certain conditions, causing serious consequences.

[0006] (3) Accelerate mechanical wear: Dust will accelerate the wear of mechanical equipment and shorten the service life of the equipment.

[0007] (4) Affects visibility and work safety: Excessive dust at the work site will reduce visibility in the workplace and increase the chance of mechanical personal injury accidents.

[0008] In existing technologies, dust removal is generally carried out by spraying, but this method has the following technical drawbacks:

[0009] (1) The mining environment is relatively complex and water supply is inconvenient. Portable water tanks are generally used as water sources for spraying. The spraying structure is relatively simple and cannot achieve efficient spraying effect.

[0010] (2) In the prior art, the water in the tank is pressurized first, and then the water is led to the spray head through the spray pipe for spraying. After the spraying is finished, the pipeline needs to be manually cut off, which is very inconvenient. Utility Model Content

[0011] To address the technical problems of poor spraying effect and inconvenient operation in existing mining dust removal systems, this utility model provides an electromagnetic braking dust removal device for mining, which improves the spraying effect and uses electromagnetic braking to cut off the water spray pipe, making it fast and easy to operate.

[0012] This utility model provides an electromagnetic braking dust removal device for mining, including a water tank, and further comprising:

[0013] A water storage tank is installed on the upper surface of the water tank.

[0014] The pressurization mechanism includes a pressurization pump installed on the bottom plate inside the water tank, and the outlet pipe of the pressurization pump is connected to the inside of the water storage tank through a high-pressure pipeline;

[0015] The spraying mechanism includes a water pipe closed at both ends, several atomizing nozzles inserted into the water pipe, a connecting pipe connected to the middle of the water pipe, the connecting pipe being inserted into the side wall of the water storage tank, and the opening of the connecting pipe being located inside the water storage tank.

[0016] The rotating mechanism includes a housing embedded in the side wall of the water storage tank, and a motor is installed inside the housing;

[0017] The braking mechanism includes a connecting block, one side of which is fixedly connected to a motor drive rod, and the other side is fixedly connected to a rotating shaft. The rotating shaft is located inside a connecting pipe. A coil box is provided on the outer surface of the connecting pipe opening, and a coil is wound inside the coil box. A circular iron plate for sealing the connecting pipe opening is provided between the connecting pipe opening and the connecting block. The rotating shaft passes through the circular iron plate, and the circular iron plate is connected to the connecting block by a leaf spring. When the leaf spring is in its natural state, there is a gap between the circular iron plate and the connecting pipe opening.

[0018] A fixing mechanism, located inside the water spray pipe, is used to fix the end of the connecting pipe to the water spray pipe.

[0019] Furthermore, the upper surface of the water tank has an opening, and the lower surface of the water tank is fixed to the base.

[0020] Furthermore, a solenoid valve is installed at the inlet of the booster pump. The solenoid valve opens before the booster pump starts working and remains closed when not in operation.

[0021] Furthermore, a layer of rubber is bonded to the outer surface of the circular iron plate. This serves to enhance the sealing effect of the circular iron plate on the opening of the connecting pipe.

[0022] Furthermore, a bearing is installed at the insertion point between the connecting pipe and the side wall of the water storage tank. This facilitates the rotation of the connecting pipe, and a bearing seal is provided at the bearing to enhance sealing.

[0023] Furthermore, the fixing mechanism includes a mounting plate that is vertically fixed to the inner wall of the water spray pipe, a sleeve that is fixed to the outer side of the mounting plate, and the end of the rotating shaft is inserted into the sleeve and fixed to the inner wall of the sleeve.

[0024] The beneficial effects of this utility model are as follows:

[0025] (1) This utility model uses a rotating mechanism to drive the spraying mechanism to rotate, so that the water stored in the water tank enters the rotating connecting pipe and is then sprayed out at the atomizing nozzle, thereby increasing the spraying area, expanding the spraying range, and achieving efficient spraying dust removal.

[0026] (2) This utility model adopts an electromagnetic braking mechanism. When dust removal is paused or completed, the pressurizing pump stops working, and then the spray pipe is cut off by electromagnetic braking. It is fast, convenient to operate, and saves water consumption. Attached Figure Description

[0033] Example 1

[0034] Combination Figures 1-3 This utility model provides an electromagnetic braking dust removal device for mining, comprising:

[0035] Water tank 2 is used to store water. The upper surface of water tank 2 has a tank opening 10 for adding water. The lower surface of water tank 2 is fixed on the base 1 to enhance stability.

[0036] Water storage tank 5 is installed on the upper surface of water tank 2 and is used to temporarily store the incoming water of water tank 2.

[0037] The pressurizing mechanism 7 includes a pressurizing pump 703 installed on the bottom plate inside the water tank 2. A solenoid valve 702 is provided at the inlet of the pressurizing pump 703's water inlet pipe 701. The outlet pipe 704 of the pressurizing pump 703 is connected to the inside of the water storage tank 5 through a high-pressure pipeline 705.

[0038] The spraying mechanism 4 includes a water pipe 401 closed at both ends, a number of atomizing nozzles 402 inserted into the water pipe 401, a connecting pipe 3 connected to the middle of the water pipe 401, the connecting pipe 3 being inserted into the side wall of the water storage tank 5, a bearing being provided at the insertion point to facilitate the rotation of the connecting pipe 3, and the opening of the connecting pipe 3 being located inside the water storage tank 5.

[0039] The rotating mechanism 9 includes a housing 901 embedded in the side wall of the water storage tank 5, and a motor is installed inside the housing 901;

[0040] The braking mechanism 6 includes a connecting block 601. One side of the connecting block 601 is fixedly connected to the motor drive rod, and the other side is fixedly connected to the rotating shaft 604. The rotating shaft 604 is located inside the connecting pipe 3. A coil box 605 is provided on the outer surface of the opening of the connecting pipe 3. A coil is wound inside the coil box 605. A circular iron plate 603 for sealing the opening of the connecting pipe 3 is provided between the opening of the connecting pipe 3 and the connecting block 601. A rubber layer is bonded to the outer surface of the circular iron plate 603. The rotating shaft 604 passes through the circular iron plate 603. The circular iron plate 603 and the connecting block 601 are connected by a leaf spring 602. When the leaf spring 602 is in its natural state, there is a gap between the circular iron plate 603 and the opening of the connecting pipe 3.

[0041] The fixing mechanism 8 includes a mounting plate 801 vertically fixed to the inner wall of the water spray pipe 401. A sleeve 802 is fixed to the outer side of the mounting plate 801. The end of the rotating shaft 604 is inserted into the sleeve 802 and fixed to the inner wall of the sleeve 802. Its function is to fix the end of the connecting pipe 3 to the water spray pipe 401, so that the rotation of the connecting pipe 3 drives the rotation of the water spray pipe 401.

[0042] The working process of this utility model is as follows: Water is added to the water tank 2 through the tank opening 10. When dust removal is required in the mining environment, the solenoid valve 702 is opened, the motor in the housing 901 is started, and the rotating shaft 604 is rotated, which in turn drives the connecting pipe 3 and the water spray pipe 401 to rotate. The pressure pump 703 is started, and water is led to the water storage tank 5 through the water outlet pipe 704 and the high pressure pipeline 705. After entering the connecting pipe 3, it is sprayed out at the atomizing nozzle 402. When the dust removal spraying is finished, the pressure pump 703 is turned off. At the same time, the coil in the coil box 605 is energized to generate magnetism, attracting the circular iron plate 603 to move towards the opening of the connecting pipe 3, covering and sealing the pipe. Water no longer enters the connecting pipe 3, preventing water from continuing to spray out at the atomizing nozzle 402 under residual pressure. This achieves rapid braking of the water spray and is convenient to operate.

[0043] When spraying needs to continue, the coil inside the coil box 605 is de-energized, and the circular iron plate 603 returns to its initial state under the tension of the leaf spring 602. The circular iron plate 603 detaches from the water inlet and re-enters the pipe, repeating the above operation to continue spraying and dust removal.

[0044] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
