Description

Technical Field

[0001] This utility model relates to the field of mining drilling rig technology, specifically a dust suppression device for mining drilling rigs. Background Technology

[0002] Mining drilling rigs are mechanical equipment used for drilling operations during mining operations. They are mainly used for water exploration, gas exploration, coal seam water injection, geological exploration, and other work. During the drilling process, the drilling rig generates a large amount of coal dust, rock dust, and other dust. These dust particles are extremely small and can be easily inhaled by workers. At the same time, coal dust in coal mines and other mines is combustible dust. When the dust concentration reaches the explosion limit, it can easily cause a dust explosion accident when it encounters mechanical sparks, electrical sparks, or other ignition sources generated by the drilling rig, resulting in significant casualties and property damage.

[0003] However, existing technologies still have the following problems: Existing dust suppression devices for mining drilling rigs mostly adopt a single dust suppression method, or simply filter, which is difficult to remove harmful gases and fine particles, or spray, which is not comprehensive enough to quickly settle most of the dust. This results in high dust concentrations in the mine, which not only threatens the health of operators but also increases the risk of dust explosions.

[0004] Secondly, existing devices often lack flexible and mobile structures, making them difficult to adapt to the complex working environment of mines and unable to be easily adjusted to different working areas; moreover, most filter components are fixed structures, making replacement and cleaning operations cumbersome, with high maintenance costs and difficulties, which affects the efficiency of the device.

[0005] To address the aforementioned problems, the inventors have proposed a dust suppression device for mining drilling rigs. Utility Model Content

[0006] To address the problem that most dust suppression devices for mining drilling rigs employ a single dust suppression method and lack a flexible, mobile structure, the purpose of this utility model is to provide a dust suppression device for mining drilling rigs.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: a dust suppression device for mining drilling rigs, comprising a housing, a treatment liquid tank on the upper side of the housing, a cover plate snapped onto the upper surface of the treatment liquid tank, an input pipe fixed on one side of the housing, a dust collection component on one side of the input pipe, and a dust collection hopper on one side of the dust collection component, an air outlet pipe connected to the upper surface of the housing, and an activated carbon disc detachably arranged at equal intervals inside the input pipe, an insert plate movably inserted into the upper surface of the input pipe, and the insert plate and the activated carbon disc being detachably connected, connecting blocks arranged in a ring on the upper surface of the activated carbon disc, and locking blocks arranged in a ring symmetrically fixed on both sides of the lower surface of the insert plate, the connecting blocks being locked between corresponding two locking blocks, and the locking blocks and connecting blocks being connected by bolts, and a handle fixedly provided on the upper surface of the insert plate.

[0008] Preferably, a support block is fixed between the treatment liquid tank and the tank body, and a solenoid valve is provided inside the support block. The upper end of the solenoid valve is connected to the treatment liquid tank, and a transmission pipe is provided at the lower end of the solenoid valve. An inclined pipe distributed in a ring is connected to the outer surface of the transmission pipe, and a side nozzle is provided on the lower side of the outer surface of the inclined pipe. A main nozzle is provided at the lower end of the transmission pipe.

[0009] Preferably, one side of the housing is provided with an input groove for use with the input pipe, and the size of the input groove is the same as the inner diameter of the input pipe. Locking blocks are symmetrically fixed on both sides of the outer surface of the input pipe, and the locking blocks are connected to the corresponding insert plates by bolts. The upper surface of the input pipe is provided with a slot for use with the insert plate. Sealing strips are symmetrically fixed on both sides of the upper surface of the insert plate, and the sealing strips are in movable contact with the input pipe.

[0010] Preferably, a push handle is fixedly provided on the upper part of one side of the box, and universal wheels are symmetrically provided on the lower surface of the box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention employs a dual treatment method of adsorption filtration and spray sedimentation. The activated carbon disc can effectively adsorb harmful gases and fine particles in the dust, while the spray system forms an all-round coverage through side nozzles and main nozzles, which can quickly wet and settle most of the dust, significantly reducing the dust concentration in the mining operation environment, reducing the harm of dust to the health of operators, and reducing the risk of dust explosion.

[0012] This invention utilizes a combination of casters and a push handle, enabling the device to move flexibly to different work areas and adapt to the complex working environment of the mine. The activated carbon disc has a detachable structure, allowing for easy removal of the insert plate for replacement or cleaning via the handle. This simple and convenient operation reduces maintenance costs and difficulty. Attached Figure Description

[0019] Example: Figure 1-3 As shown, this utility model provides a dust suppression device for mining drilling rigs, including a housing 1. A treatment liquid tank 3 is located on the upper side of the housing 1, and a cover plate 37 is fitted onto the upper surface of the treatment liquid tank 3. An input pipe 2 is fixedly installed on one side of the housing 1, and a dust collection component 4 is located on one side of the input pipe 2. A dust collection hopper 41 is located on one side of the dust collection component 4. An air outlet pipe 13 is connected to the upper surface of the housing 1. Activated carbon discs 21 are detachably installed at equal intervals inside the input pipe 2. An insert plate 22 is movably inserted into the upper surface of the input pipe 2, and the insert plate 22 is detachably connected to the activated carbon discs 21. Connecting blocks 23 arranged in a ring are embedded in the upper surface of the activated carbon discs 21. Locking blocks 24 arranged in a ring are symmetrically fixed on both sides of the lower surface of the insert plate 22. The connecting blocks 23 are locked onto corresponding... Between the two locking blocks 24, and the locking blocks 24 and the connecting block 23 are connected by bolts, the upper surface of the insert plate 22 is fixedly provided with a handle 27. After the dust collection component 4 is started, the dust generated by drilling will enter the input pipe 2 through the dust collection hopper 41 under the suction of the dust collection component 4. When the dust is transported in the input pipe 2, it first passes through the activated carbon discs 21 arranged at equal intervals. The activated carbon discs 21 perform preliminary adsorption and filtration of harmful gases and some fine dust in the dust. The activated carbon discs 21 are locked between the annularly distributed locking blocks 24 symmetrically fixed on both sides of the lower surface of the insert plate 22 through the annularly distributed connecting blocks 23 embedded on the upper surface. The locking blocks 24 and the connecting blocks 23 are fixed by bolts. The insert plate 22 is movably inserted into the slot 26 on the upper surface of the input pipe 2.

[0020] A support block 31 is fixedly installed between the treatment liquid tank 3 and the tank body 1. An electromagnetic valve 33 is installed inside the support block 31. The upper end of the electromagnetic valve 33 is connected to the treatment liquid tank 3, and the lower end of the electromagnetic valve 33 is connected to a transmission pipe 32. An annularly distributed inclined pipe 34 is connected to the outer surface of the transmission pipe 32, and a side nozzle 35 is installed on the lower side of the outer surface of the inclined pipe 34. A main nozzle 36 is installed at the lower end of the transmission pipe 32. Under the control of the electromagnetic valve 33, the dust-suppressing treatment liquid in the treatment liquid tank 3 is transported downwards through the transmission pipe 32. The treatment liquid tank 3 is fixed to the upper side of the housing 1 by a support block 31. The solenoid valve 33 is located inside the support block 31 and its upper end is connected to the treatment liquid tank 3. The annular distribution inclined pipe 34 connected to the outer surface of the transmission pipe 32 diverts part of the treatment liquid, which is sprayed into both sides of the housing 1 through the side nozzles 35 on the lower side of the inclined pipe 34. The main nozzle 36 at the lower end of the transmission pipe 32 sprays the remaining treatment liquid into the lower part of the housing 1, forming an all-round spray area to further wet and settle the dust that has been initially filtered. The gas after dust suppression is discharged from the housing 1 through the exhaust pipe 13 connected to the upper surface of the housing 1.

[0021] A slot 11 for use with the input pipe 2 is provided on one side of the housing 1, and the size of the slot 11 is the same as the inner diameter of the input pipe 2. Locking blocks 25 are symmetrically fixed on both sides of the outer surface of the input pipe 2, and the locking blocks 25 are connected to the corresponding insert plates 22 by bolts. A slot 26 for use with the insert plates 22 is provided on the upper surface of the input pipe 2. Sealing strips 28 are symmetrically fixed on both sides of the upper surface of the insert plates 22, and the sealing strips 28 are movably fitted with the input pipe 2. The input pipe 2 connects to the housing 1 via the slot 11 on one side. The internal structure of the body 1 is interconnected, and the size of the input slot 11 matches the inner diameter of the input pipe 2, ensuring that dust can smoothly enter the body 1. At the same time, the locking block 25 and the corresponding insert plate 22 are fixed by bolts to ensure that the activated carbon disc 21 remains stable during operation. When the activated carbon disc 21 needs to be replaced or cleaned, the operator can hold the handle 27 and pull out the insert plate 22 upwards. The sealing strips 28 on both sides of the upper surface of the insert plate 22 are in contact with the input pipe 2 when inserted, which plays a role in sealing and preventing dust from leaking from the slot 26.

[0022] A push handle 5 is fixedly installed on the upper side of one side of the housing 1, and casters 51 are symmetrically provided on the lower surface of the housing 1. During the operation of the mining drilling rig, the operator can push the housing 1 with the push handle 5 and move the entire device to a suitable working position with the help of the casters 51 on the lower surface of the housing 1.

[0023] The solenoid valve 33 and the dust collection component 4 are existing technologies and will not be described in detail. In addition, this utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0024] Working Principle: During the operation of the mining drilling rig, the operator can push the housing 1 using the push handle 5, and move the entire device to a suitable working position using the casters 51 on the lower surface of the housing 1. After activating the dust collection component 4, the dust generated during drilling will be drawn into the input pipe 2 through the dust collection hopper 41 by the suction force of the dust collection component 4. The input pipe 2 is connected to the inside of the housing 1 through an input slot 11 opened on one side of the housing 1, and the size of the input slot 11 matches the inner diameter of the input pipe 2, ensuring that the dust enters the housing 1 smoothly. When the dust is transported in the input pipe 2, it first passes through the activated carbon discs 21 arranged at equal intervals. The activated carbon discs 21 perform preliminary adsorption and filtration of harmful gases and some fine dust in the dust. The activated carbon disc 21 is engaged between the annularly distributed connecting blocks 23 embedded on the upper surface and the annularly distributed locking blocks 24 symmetrically fixed on both sides of the lower surface of the insert plate 22. The locking blocks 24 and the connecting blocks 23 are fixed with bolts. The insert plate 22 is movably inserted into the slot 26 on the upper surface of the input pipe 2. At the same time, the locking block 25 is fixed with the corresponding insert plate 22 by bolts to ensure that the activated carbon disc 21 remains stable during operation. Subsequently, the dust-suppressing treatment liquid in the treatment liquid tank 3 is transported downwards through the transmission pipe 32 under the control of the solenoid valve 33. The treatment liquid tank 3 is fixed to the upper side of the housing 1 by the support block 31. The solenoid valve 33 is located inside the support block 31 and its upper end is connected to the treatment liquid tank 3. The annular distribution inclined pipe 34 connected to the outer surface of the transmission pipe 32 diverts part of the treatment liquid, which is sprayed into both sides of the housing 1 through the side nozzles 35 on the lower side of the inclined pipe 34. The main nozzle 36 at the lower end of the transmission pipe 32 sprays the remaining treatment liquid into the lower part of the housing 1, forming an all-round spray area to further wet and settle the pre-filtered dust. The gas after dust suppression is completed is discharged from the housing 1 through the exhaust pipe 13 connected to the upper surface of the housing 1. When the activated carbon disc 21 needs to be replaced or cleaned, the operator can hold the handle 27 and pull out the insert plate 22 upwards. The sealing strips 28 on both sides of the upper surface of the insert plate 22 are in contact with the input pipe 2 when inserted, which plays a role in sealing and preventing dust from leaking out of the slot 26.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
