Description

Technical Field

[0001] This utility model relates to the field of energy-saving dust removal technology in mining, and in particular to a mobile energy-saving dust removal device for mining. Background Technology

[0002] During mineral extraction, drilling, blasting, and transportation processes generate large amounts of dust, which not only severely pollutes the working environment but also poses significant occupational health risks. High concentrations of dust also pose safety hazards such as dust explosions and reduce visibility, increasing the risk of accidents. While fixed dust collection systems offer some efficiency, their coverage is rigid and cannot move with dynamic dust sources such as mining and transportation, resulting in many dust-generating points becoming dust collection blind spots. Dry equipment such as baghouse dust collectors are costly, have poor adaptability, and are inconvenient to move. Existing mobile dust collection devices lack energy-saving design features. Therefore, a mobile, energy-saving mining dust collection device is needed to achieve low energy consumption, mobility, and a wide coverage area.

[0003] Chinese patent document CN210145747U discloses a mobile mining dust removal device, including a base and a mounting plate. The mounting plate is located on the upper side of the base, and a spring is fixed between the mounting plate and the base. A water tank is fixed to the upper end of the mounting plate by bolts. A motor is fixed to the upper left part of the water tank by screws. A dust removal box is located on the upper side of the water tank. A fan is rotatably connected to the left part of the dust removal box. A second filter screen is fixed in the dust removal box to the right of the fan. A wind collection hood is welded and fixed to the right end of the dust removal box. Compared with the prior art, it has the following advantages: it is easy to use, facilitates dust removal by the first filter screen and the water tank, has a good dust removal effect, and the motor facilitates the rotation of the dust removal box, increasing the working area and facilitating shock absorption by the spring. The second filter screen facilitates the filtration of wastewater, facilitating water recycling and reducing water waste.

[0004] However, the aforementioned patent documents still have the following defects in implementation: the complex structure of the device increases the difficulty of manufacturing and assembly, and the complex structure may lead to more failure points during operation, such as the gear meshing part may be affected by wear, thus affecting the rotation effect; in addition, when there are many impurities in the sewage, filtration by the second filter screen alone may not be able to completely remove the impurities, resulting in low cleanliness of the circulating water and affecting the dust removal effect. Such a design cannot achieve the dual effect of energy saving and dust removal; the fixed-angle dust collection hood is difficult to cover dynamic dust sources, and the rotation range is limited, rotating only on the horizontal plane, making it impossible to accurately track the dust diffusion path. Utility Model Content

[0005] The main objective of this invention is to provide a mobile, energy-saving dust removal device for mining, which can effectively solve the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A mobile energy-saving dust removal device for mining includes a mobile base. A water tank is fixedly connected to the upper end of the mobile base.

[0016] 1.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1

[0026] like Figure 1 As shown, a mobile energy-saving mining dust removal device includes a mobile base 1, which can be moved within the mine or mine shaft as needed to meet dust removal requirements at different locations. A water tank 6 is fixedly connected to the upper end of the mobile base 1. The water tank 6 contains a liquid for dust removal, such as special coal mine dust removal fluid, filtered water, or tap water, which allows mineral dust to adhere to these liquids and fall to the ground under gravity. Two metal plates 7 are rotatably connected to the right end of the water tank 6 via a rotating bearing. The metal plates 7 can rotate with the rotating bearing. A power generation device 5 is fixedly connected to the upper end of the water tank 6. A power generation device is installed on the upper right side of the water tank 6. The water pump 2 is fixedly connected to the outlet of the water tank 6 at the right end of the power-assisted rotation device 4. The spraying device 8 is connected to the right end of the two metal plates 7 through multiple movable buckles. The movable buckles are used to fix the position of the spraying device 8. When there are damaged parts of the spraying device 8, they can be disassembled and replaced in time by opening the movable buckles. A support mechanism 9 is set on the right side of the spraying device 8. The lower end of the support mechanism 9 is threaded to the upper end of the movable base 1. A three-way pipe 3 is installed at the output end of the water pump 2. The water outlet of the three-way pipe 3 is connected to the water inlet of the spraying device 8. The dust removal liquid is pumped out from the output end of the water pump 2 and flows to the spraying device 8 through the three-way pipe 3.

[0027] Furthermore, such as Figure 2 and Figure 4As shown, the spraying device 8 includes six rigid pipes 81. Each of the six rigid pipes 81 has a number of nozzles 82 threaded onto its outer surface. The six rigid pipes 81 are divided into two groups and symmetrically distributed on both sides along the long axis of the water tank 6. Each group of three rigid pipes 81 are arranged vertically at intervals from top to bottom, forming a matrix array. The spray arms of the nozzles 82 are connected by universal joints, allowing manual adjustment of the spray angle to create a comprehensive spray network. Three flexible hoses 83 are installed on the side of each group of three rigid pipes 81 that are close to each other. A second rigid pipe 84 is installed on the same side of each group of three flexible hoses 83. Flexible hoses 85 are installed at the upper ends of the two second rigid pipes 84. The water pump 2 draws dust removal liquid from the outlet of the water tank 6 and pumps it into the three-way pipe 3 from the output end. The liquid flows from the other two outlets of the three-way pipe 3 into the connected flexible hoses 85, and then into the rigid pipes 84, thus entering the six rigid pipes 81 and being sprayed out from the nozzles 82.

[0028] Furthermore, to expand the spraying range and facilitate cyclic spraying within the area, combined with... Figure 1 and Figure 2 The power-assisted rotation device 4 includes a hydraulic cylinder 41. A metal plate 42 is fixedly connected to the telescopic end of the hydraulic cylinder 41. When the hydraulic cylinder 41 works, its telescopic end can drive the metal plate 42 to move back and forth. A sliding device 43 is fixedly connected to the right end of the metal plate 42. Two metal rods 44 are rotatably connected to the right end of the metal plate 42. The two metal rods 44 are located on both sides of the sliding device 43. The other ends of the two metal rods 44 are rotatably connected to the left end of the metal plate 7. When the metal plate 42 moves back and forth, it gives the metal rods 44 a certain pushing and pulling force. Along the direction of the force transmitted by the metal rods 44, the two metal plates 7 rotate around the axis, so that the spraying device 8 installed on the other side of the metal plate 7 also rotates to both sides, expanding the spraying range and making the blind areas on both sides also within the spraying range, realizing dust removal over a large area and meeting the needs of multiple scenarios in the mine. Furthermore, since the hose 83 is made of a soft material and its length is configured according to the rotatable angle of the metal plate 7, it will not cause the pipe to break and leak when the spraying device 8 rotates.

[0029] Furthermore, to achieve energy conservation, the power-assisted rotation device 4 is equipped with a device that can shut off the flow of liquid, see [reference]. Figure 3 As shown, the sliding device 43 includes a sliding base 431, and two sliders 432 are slidably connected to the sliding base 431. A push rod 433 is fixedly connected to the side of each slider 432 away from the sliding base 431.

[0030] For details, please refer to Figure 1 and Figure 3As shown, the sliding base 431 has stops on both sides of the slide rail. The two sliders 432 slide within the set slide rail length. One end of the push rod 433 is located at the center of the slider 432. Adjusting the position of the two sliders 432 can adjust the position of the push rod 433. When the center of the push rod 433 is aligned with the center line of the second hose 85, the hydraulic cylinder 41 is activated to push the metal plate 42 to move. The push rod 433 also moves forward, thereby squeezing the second hose 85 and reducing the water output. In some cases, such as when only one side needs to be sprayed, the second hose 85 can be flattened to shut off the spraying of liquid on one side, thus achieving energy saving. When the two sliders 432 are in close contact, the extension lines of the two sliders 432 fixed on the two sliders 432 do not overlap with the second hose 85. At this time, when the hydraulic cylinder 41 is working, the push rod 433 will not squeeze the second hose 85, thus ensuring that dust removal can be achieved on both sides.

[0031] Specifically, in order to ensure the squeezing effect of the push rod 433 when squeezing the hose 45 and to prevent dislocation, a support mechanism 9 is provided. The lower part of the support mechanism 9 is in the shape of a "Z", and a metal plate is fixed on the upper part of the "Z". This metal plate can prevent the push rod 433 from continuously pushing the hose 85.

[0032] In summary, during implementation, after the mobile base 1 moves the water tank 6 to the designated dust removal area, the water pump 2 draws dust removal liquid from the outlet at the right end of the water tank 6. The liquid is then diverted through the T-connector 3 at its output end to the two flexible hoses 85 on both sides of the spraying device 8. The liquid enters through the rigid pipe 84 into three vertically distributed rigid pipes 81 on each side, and is finally sprayed out by the threaded nozzles 82 to form a mist. To expand the coverage area, the hydraulic cylinder 41 pushes the metal plate 42 forward, causing the metal rods 44 on both sides to apply a lateral force to the metal plate 7, forcing the metal plate 7 to horizontally unfold around the rotating bearing at the right end of the water tank 6. The spraying device 8 then rotates to both sides, expanding the spray angle to the blind spot of traditional fixed nozzles. During the spraying process, the sliding device 43 achieves energy saving by adjusting the position of the push rod 433: when the two sliders 432 are in close contact, the push rod 433 avoids the hose 85 and sprays normally on both sides; if unilateral operation is required, the slider 432 is moved so that the push rod 433 is aligned with the hose 85, and the hydraulic cylinder 41 pushes the push rod 433 to squeeze the hose and cut off the flow, reducing the liquid output on one side or closing the liquid path on one side to reduce unnecessary consumption of dust removal liquid. The flexible design of the hose 83 ensures that the pipeline is not damaged when rotating.

[0033] Example 2

[0034] To better achieve resource conservation and ensure clean energy, please refer to Figure 5As shown, the power generation device 5 includes a metal base 51, the lower end of which is fixedly connected to the water tank 6. A hydraulic cylinder 53 is rotatably connected to the upper left side of the metal base 51, and a solar panel 52 is rotatably connected to the upper right side of the metal base 51. The telescopic end of the solar panel 52 is rotatably connected to the bottom of the solar panel 52. On sunny days, the hydraulic cylinder 53 is activated, and its telescopic end provides a certain thrust to the solar panel 52, causing the solar panel 52 to rotate upward. The solar panel 52 receives sunlight at a certain tilt angle and generates electricity, which is transmitted to the energy storage battery installed below the mobile base 1. The energy storage battery can drive the mobile base 1 to move within the mine and can also drive other devices. This method not only achieves clean energy but also saves electricity in the mine by utilizing the electricity generated by the solar panel 52.

[0035] Specifically, when the solar panel 52 is not in operation, it is in a horizontal position. That is, when the solar panel 52 is not needed for charging, or on a cloudy day, or after entering the mine, the hydraulic cylinder 2 53 is closed, so that the solar panel 52 returns to a horizontal position, thus avoiding damage to the solar panel 52.

[0036] In summary, in this embodiment, when the power generation device 5 operates independently in the open-pit mine, hydraulic cylinder 53 pushes the solar panel 52 to tilt and lift around the hinge point of the metal base 51, absorbing light energy at the optimal angle and converting it into electrical energy, which is then stored in the battery at the bottom of the movable base 1. The stored electricity can drive the water pump 2, various hydraulic systems, and the walking mechanism of the movable base 1. When entering the mine shaft or working at night, hydraulic cylinder 53 retracts to return the solar panel 52 to a horizontal position to avoid collisions.

[0037] It should be noted that the specific installation methods, circuit connection methods, and control methods of the water pump 2, hydraulic cylinder 41, hydraulic cylinder 53, and solar panel 52 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
