Description

Technical Field

[0001] This utility model relates to the field of dust control in mining, and in particular to a dust control device for mining. Background Technology

[0002] In mining operations, dust pollution not only threatens the health of workers but can also pose safety hazards. Therefore, the effectiveness and environmental adaptability of dust control devices are crucial. Existing mining dust control technologies face multiple challenges: traditional devices typically have fixed nozzle layouts, making it difficult to dynamically adjust the spray angle and coverage area according to dust concentration and diffusion direction in different areas of the mine; water tank capacities are often standardized, failing to meet the flexible operational needs of small mines or the continuous dust suppression requirements of large mines; furthermore, the devices lack adaptability to mine space dimensions (such as height and width), making it difficult to fully realize dust control effects in complex terrains or equipment layouts.

[0003] In the prior art, for example, patent CN117027916A discloses a dust suppression device for mining. This device uses a motor to drive a rotating disc, which in turn causes nozzles on a connecting rod to rotate in a circular motion to achieve multi-directional water spraying. The nozzle angle is adjusted via a universal hose. This solution simplifies the traditional multi-nozzle structure through a single-nozzle transmission mechanism, improving flexibility to some extent. However, despite these improvements, the following areas still require optimization:

[0004] 1. This device achieves planar circular motion of the nozzles only through disc transmission, but the nozzle spacing is fixed and the height is not adjustable. It cannot make precise adjustments to the spray angle and coverage for vertical dust diffusion (such as dust from falling ore at height) or dense areas, resulting in limited dust reduction efficiency in complex dust scenarios.

[0005] 2. The water tank has a fixed capacity and is integrated with the main body of the equipment. It is not possible to quickly change water tanks of different volumes according to the size of the mine (such as small tunnels or large mining faces). In scenarios that require long-term continuous operation, it is necessary to frequently stop the machine to replenish water, which affects mining efficiency. At the same time, the fixed size of the water tank is difficult to adapt to the space constraints of narrow mines.

[0006] Therefore, based on the above-stated viewpoints, there is still room for improvement in existing dust control equipment for mining. Utility Model Content

[0007] To solve the above problems, this utility model provides a dust control device for mining, including a cross plate, a support plate in the middle of the cross plate, and L-frame plates slidably fitted on the four extension sections of the cross plate. A water storage tank is placed on the upper end of the support plate, and an arc-shaped groove is opened at the end of the L-frame plate without contact with the outside of the water storage tank.

[0013] Preferably, a rectangular plate is also provided in the vertical extension section of the L-frame plate, and a reset tension spring is provided between the rectangular plate and the corresponding bent frame plate.

[0014] Preferably, a water pump is installed on the water storage tank, and a water pumping pipe extending into the water storage tank is provided at the bottom of the water pump. A water supply pipe is also provided at the top of the water pump, and the top of the water supply pipe is connected to the spraying unit.

[0015] Preferably, the spraying unit includes a main pipe that is rotatably mounted on a circular plate, a rotating pipe at the lower end of the main pipe that corresponds to the end of the water supply pipe, an annular groove at the upper end of the water supply pipe, and an annular ring at the lower end of the rotating pipe located in the annular groove. A bent pipe is provided at the upper end of the main pipe, and a telescopic pipe slides along the keyway at the end of the bent pipe. A spraying device is provided at the end of the telescopic pipe.

Detailed Implementation

[0031] The following combination Figures 1 to 8 The embodiments of this utility model will be described in detail below.

[0032] This application discloses a dust suppression device for mining. It is described that this application is used in dust suppression operations in mine tunnels. It can suppress dust generated during mining by supplying water through a water storage tank and atomizing it through a spraying unit. Furthermore, it can also adapt to water storage tanks of different specifications and perform multi-angle and multi-range spraying operations through an adjustable L-frame plate, upper unit and drive components, thereby improving dust suppression efficiency and device applicability.

[0033] Example 1: Refer to Figure 1 and Figure 2 As shown, it includes a cross plate 1, a support plate 10, an L-frame plate 11 and a water storage tank 12. The support plate 10 is provided in the middle of the cross plate 1, and the L-frame plate 11 is slidably fitted on the four extension sections of the cross plate 1, that is, the L-frame plate 11 can reciprocate at the upper end of the extension section of the cross plate 1.

[0034] A water storage tank 12 is placed on the upper end of the support plate 10, and an arc-shaped groove is opened at the end of the L-frame plate 11 that does not contact the outside of the water storage tank 12. The cross plate 1 can support the water storage tank 12 through the support plate 10, and the L-frame plate 11 can be moved on the cross plate 1 so that the arc-shaped groove at its end contacts the outside of the water storage tank 12, thereby further limiting the water storage tank 12 and preventing the water storage tank 12 from shaking.

[0035] A fixing component 3 is also provided between the cross plate 1 and the L frame plate 11. After the L frame plate 11 has moved, the fixing component 3 can fix the L frame plate 11 to the cross plate 1 to prevent it from shifting.

[0036] The L-frame plate 11 is provided with an upper unit 4 for limiting the upper end of the water storage tank 12. The upper unit 4 is used to limit and fix the upper end of the water storage tank 12 to prevent the water storage tank 12 from tilting. The upper unit 4 is also provided with a spraying unit 6 connected to the water storage tank 12. The water storage tank 12 supplies water to the spraying unit 6, and the spraying unit 6 sprays water mist into the mine to suppress dust.

[0037] Continue to refer to Figure 2 As shown, specifically, it includes casters 2. Casters 2 are installed at the lower end of the L-frame plate 11, which means that the device can be moved freely in the mine through the casters 2.

[0038] Reference Figure 3 As shown, the fixing component 3 is used to limit and fix the L-frame plate 11 and the cross plate 1; specifically, the fixing component 3 includes fixing bolts 30, and fixing grooves are opened on the four extension sections of the L-frame plate 11 and the cross plate 1, with fixing bolts 30 threadedly inserted into the upper and lower corresponding fixing grooves.

[0039] According to the size of the mine shaft and the usage requirements, water storage tanks 12 of different sizes can be installed on the support plate 10. Then, according to the size of the water storage tank 12, the position of the L-frame plate 11 on the cross plate 1 is moved so that the arc groove at the end of the L-frame plate 11 contacts the outside of the water storage tank 12. Then, the fixing bolts 30 are inserted into the corresponding two fixing grooves to achieve the effect of fixing the L-frame plate 11 on the extension section of the cross plate 1.

[0040] Reference Figure 4 As shown, the upper unit 4 limits the upper end of the water storage tank 12; specifically, the upper unit 4 includes a bent frame plate 40, a sliding plate 41, a circular plate 42, a contact plate 43, a rectangular plate 44, and a reset spring 45. The bent frame plate 40 is slidably disposed in the vertical section of the L-frame plate 11, that is, the bent frame plate 40 can move up and down in the L-frame plate 11; the sliding plate 41 slides in the lateral extension section of the bent frame plate 40, and the sliding plate 41 can move towards or away from the water storage tank 12 in the bent frame plate 40.

[0041] A circular plate 42 is provided between the sliding plates 41. A contact plate 43 is provided at the lower end of the circular plate 42, and the contact plate 43 contacts the upper end of the water storage tank 12. During the movement of the sliding plates 41, the axis of the circular plate 42 can always correspond to the axis of the water tank. That is, when the bending plate moves on the cross plate 1, it can drive the bending frame plate 40 to move synchronously. When the bending frame plate 40 moves, the sliding plates 41 and the bending frame plate 40 are slidably connected, so that the circular plate 42 is in its original position. After the water storage tank 12 is installed on the support plate 10, the height of the bending frame plate 40 is moved according to the height of the water storage tank 12, so that the circular plate 42 can drive the contact plate 43 to contact the upper end of the water storage tank 12, which plays a fixed and limiting role on the upper end of the water storage tank 12, and further limits the water storage tank 12. The spraying unit 6 is installed on the circular plate 42, that is, the circular plate 42 can support the spraying unit 6.

[0042] A rectangular plate 44 is also provided in the vertical extension section of the L-frame plate 11, and a reset spring 45 is provided between the rectangular plate 44 and the corresponding bent frame plate 40. The reset spring 45 can pull the bent frame plate 40 through the limiting of the rectangular plate 44, so that the bent frame plate 40 can indirectly drive the abutment plate 43 to continuously abut and limit the upper end of the water storage tank 12. When replacing the water storage tank 12, the bent frame plate 40 is pulled upward by external force, and then the L-frame plate 11 is limited by the fixing bolt 30. In addition, when the L-frame plate 11, the bent frame plate 40 and the sliding plate 41 in this device are adaptively extended and retracted, the volume of the device itself will also increase or decrease to adapt to mines of different sizes.

[0043] Continue to refer to Figure 4As shown, specifically, it includes a water pump 5, a water pumping pipe 50, and a water supply pipe 51. The water pump 5 is installed on the upper end of the water storage tank 12. The bottom of the water pump 5 is provided with a water pumping pipe 50 extending into the water storage tank 12, and the upper end of the water pump 5 is also provided with a water supply pipe 51. The upper end of the water supply pipe 51 is connected to the spraying unit 6.

[0044] That is, the water pump 5 can draw water from the water storage tank 12 into its body through the water pumping pipe 50, and then the water pump 5 can supply water to the spraying unit 6 through the water supply pipe 51.

[0045] Reference Figure 5 , Figure 6 and Figure 7 As shown, this is the spraying unit 6 used for spraying water mist. Specifically, the spraying unit 6 includes a main pipe 60, a rotating pipe 61, an annular ring 62, a bent pipe 63, a telescopic pipe 64, a spraying device 65, and a sealing ring 66. The main pipe 60 is rotatably mounted on the upper end of the circular plate 42, meaning that the main pipe 60 can rotate on the circular plate 42. The lower end of the main pipe 60 has a rotating pipe 61 corresponding to the end of the water supply pipe 51. The upper end of the water supply pipe 51 has an annular groove, and the lower end of the rotating pipe 61 is provided with an annular ring 62 located in the annular groove. Water in the water supply pipe 51 can enter the main pipe 60 through the rotating pipe 61. During the rotation of the main pipe 60, since the annular ring 62 at the lower end of the rotating pipe 61 is inserted into the annular groove, it not only has a sealing effect but also prevents the rotating pipe 61 from rotating, ensuring that only the main pipe 60 can rotate, thus preventing the rotating pipe 61 from rotating and rubbing against the end of the water supply pipe 51, which could lead to leakage.

[0046] The upper end of the main pipe 60 is provided with a bent pipe 63, and a telescopic pipe 64 is slidably connected to the keyway at the end of the bent pipe 63. A spraying device 65 is provided at the end of the telescopic pipe 64.

[0047] That is, the main pipe 60 can drive the bent pipe 63 to rotate synchronously along its axis, and the telescopic pipe 64 can drive the spraying device 65 at its end to slide and adjust synchronously on the bent pipe 63, changing the extension length of the spraying device 65. The telescopic pipe 64 and the bent pipe 63 can be locked together by a snap-fit ​​component, so that when the bent pipe 63 drives the telescopic pipe 64 to rotate, the telescopic pipe 64 will not slide accidentally. The telescopic pipe 64 will only slide when manually adjusted.

[0048] Water in the main pipe 60 can flow into the spraying device 65 through the bend pipe 63 and the telescopic pipe 64, so that the spraying device 65 has a sufficient water supply to spray water mist to suppress dust in the mine.

[0049] The spraying device 65 is hinged to the telescopic pipe 64, and a sealing ring 66 is installed at the hinge. The two ends of the sealing ring 66 are connected to the telescopic pipe 64 and the spraying device 65 respectively. This allows the spraying angle of the spraying device 65 to be adjusted according to actual use needs. The sealing ring 66 is used to seal the hinge gap between the telescopic pipe 64 and the spraying device 65 to prevent water leakage.

[0050] Reference Figure 8 As shown, the circular plate 42 is provided with a drive assembly 7 for driving the main pipe 60 to rotate; specifically, the drive assembly 7 includes a transmission gear 70, a drive motor 71 and a drive gear 72. The transmission gear 70 is sleeved on the outside of the main pipe 60, that is, the transmission gear 70 can drive the main pipe 60 to rotate when it is driven by an external force.

[0051] A drive motor 71 is mounted on the circular plate 42 via a motor mount. A drive gear 72 that meshes with a transmission gear 70 is sleeved on the outer side of the main shaft of the drive motor 71. The main shaft of the drive motor 71 can drive the drive gear 72 to rotate, so that the drive gear 72 can drive the main pipe 60 to rotate through the transmission gear 70.

[0052] During operation: First step: According to the size of the mine space and the dust reduction requirements, select a water storage tank 12 with an appropriate capacity and place it on the support plate 10 in the middle of the cross plate 1. At this time, the water storage tank 12 is supported by the support plate 10. Push the L frame plate 11 to slide along the four extension sections of the cross plate 1, so that the arc groove at the end of the L frame plate 11 fits against the outer wall of the water storage tank 12. The arc surface structure of the arc groove limits the water storage tank 12 in the circumferential direction and reduces horizontal shaking.

[0053] Step 2: After the L-frame plate 11 is moved to a position that is in close contact with the outer wall of the water storage tank 12, take the fixing bolts 30 and insert them into the corresponding fixing grooves on the upper and lower parts of the L-frame plate 1 and the extension section of the cross plate 1 in sequence. Tighten the fixing bolts 30 by thread to firmly fix the L-frame plate 11 on the cross plate 1 to prevent it from shifting during the movement or operation of the device.

[0054] Step 3: Based on the height of the water storage tank 12, manually move the bent frame plate 40 within the vertical section of the L-frame plate 11 upwards or downwards. This causes the lateral extension of the bent frame plate 40 to move the sliding plate 41 and the circular plate 42 up and down until the contact plate 43 at the lower end of the circular plate 42 contacts the upper surface of the water storage tank 12. At this point, the sliding plate 41 can adaptively slide within the lateral extension of the bent frame plate 40, ensuring that the axis of the circular plate 42 is always aligned with the axis of the water storage tank 12, thus achieving precise positioning of the upper end of the water storage tank 12.

[0055] Step 4: Start the water pump 5 installed on the upper end of the water storage tank 12. The water pump 5 draws water through the water pipe 50 extending from the bottom into the water storage tank 12. After being pumped internally, the water is delivered to the spraying unit 6 through the water supply pipe 51 at the upper end. During this process, the connection structure between the water supply pipe 51 and the spraying unit 6 ensures stable water flow and no leakage.

[0056] Step 5: The drive assembly 7 starts the drive motor 71. The motor spindle drives the drive gear 72 to rotate, and through the meshing transmission gear 70, the main pipe 60 rotates around the axis on the circular plate 42. When the main pipe 60 rotates, it drives the upper bent pipe 63 to rotate synchronously. The extension length of the telescopic pipe 64 at the end of the bent pipe 63 can be adjusted by the snap-fit ​​assembly, changing the horizontal coverage radius of the spraying device 65. At the same time, the sealing ring 66 at the hinge of the spraying device 65 and the telescopic pipe 64 allows manual adjustment of the spraying angle to adapt to the dust suppression needs of different areas in the mine. Water flows through the main pipe 60, the bent pipe 63, and the telescopic pipe 64 into the spraying device 65, and is sprayed into the mine through the atomization structure to suppress dust diffusion.

[0057] Step 6: When it is necessary to adjust the working position of the device in the mine, push the device to move freely via the universal wheels 2 at the lower end of the L-frame plate 11. After moving to the target position, the L-frame plate 11 can be locked again by the fixing component 3 to ensure the stability of the device during the spraying operation. When it is necessary to replace the water tank 12 of a different size, loosen the fixing bolts 30 to remove the L-frame plate 11, and repeat the above steps to complete the installation and positioning of the new water tank 12. At the same time, the bending frame plate 40, sliding plate 41 and other components automatically adapt to the size of the new water tank 12 through the reset spring 45 and the self-adaptive sliding structure, so as to realize the rapid response of the device to different working conditions.
