Description

Technical Field

[0001] The utility model relates to the technical field of coal mining equipment, in particular to a spray dust reduction device for coal mining. Background Technique

[0002] Coal mining often generates a large amount of dust. These dusts will not only affect the physical health of miners, and long-term inhalation may lead to respiratory diseases, but also pose an explosion risk. At the same time, from the perspective of the working environment, a large amount of dust will reduce visibility, affect the operation vision of miners, and increase the probability of operation errors, thus triggering safety accidents. At this time, it is necessary to use a spray dust reduction device to carry out dust reduction treatment on the dust generated during coal mining;

[0003] A spray dust reduction device is an important device for reducing the dust content in the air and improving the environmental quality. The working principle of the spray dust reduction device is usually to atomize water into fine water droplets through high pressure and then spray them into the air. These fine water droplets collide and combine with the dust particles in the air, increasing the weight of the dust particles, thereby accelerating their settlement and achieving the effect of dust reduction;

[0004] However, the angle of the traditional spray dust reduction device is relatively single, and it is difficult to adjust the angle of the device according to the actual situation to make the internal water droplets spray to the designated area, reducing the efficiency of dust reduction for the dust generated during coal mining and making it difficult to achieve the expected dust reduction effect. Therefore, a spray dust reduction device for coal mining is proposed to solve the above problems. Content of the Utility Model

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Refer to Figure 1 - Figure 3 , an embodiment provided by the present invention: a spray dust reduction device for coal mine mining, including a bottom plate 8, a motor 1 9 is fixedly connected to one side of the top of the bottom plate 8, a motor 2 16 is fixedly connected to the other side of the top of the bottom plate 8, a connecting block 1 10 is fixedly connected to the output end of the motor 1 9, a worm 18 is fixedly connected to the output end of the motor 2 16, the inner part of the connecting block 1 10 is slidably connected to the outer wall of the worm 18, a connecting ring 11 is fixedly connected to the outer wall of the connecting block 1 10, a connecting column 12 is slidably connected to the inner part of the connecting ring 11, a worm gear 13 is fixedly connected to the outer wall of the connecting column 12, the worm gear 13 and the worm 18 are meshed with each other, a connecting block 2 15 is fixedly connected to the inner wall of the connecting ring 11, the inner part of the connecting block 2 15 is slidably connected to the outer wall of the worm 18, support blocks 1 14 are fixedly connected to both ends of the connecting column 12, a spray pipe 5 is fixedly connected to the top of the support blocks 1 14, a support block 2 19 is fixedly connected to the outer wall of the support blocks 1 14, a cleaning assembly is arranged on the outer wall of the spray pipe 5, the cleaning assembly is used for cleaning the filtering component, the cleaning assembly includes a fixed block 20, the inner wall of the fixed block 20 is fixedly connected to the outer wall of the spray pipe 5, a plurality of support frames 17 are slidably connected to the outer wall of the worm 18, the bottom of the support frames 17 is fixedly connected to the top of the bottom plate 8, and one side of the support block 2 19 is fixedly connected to the outer wall of the spray pipe 5.

[0034] Specifically, during the actual use of the spray dust suppression equipment, first start the first motor 9. Using the driving force at the output end of the first motor 9, drive the connecting block 10 fixedly connected thereto to perform a rotational motion. When the connecting block 10 rotates, it will cause the connecting ring 11 to also perform a synchronous rotational motion. And during the rotation of the connecting ring 11, drive the spray pipe 5 to perform a left - right angle adjustment motion through the adjacent first support block 14 and second support block 19. When it is necessary to adjust the angles on the front and rear sides of the spray pipe 5, next start the second motor 16. Use the output end of the second motor 16 to drive the worm 18 fixedly connected thereto to perform a synchronous rotation. Use the support frame 17 to support the worm 18. Then use the rotational motion of the worm 18 to further drive the worm gear 13 to start a synchronous rotational motion. While the worm gear 13 rotates, it will drive the first support block 14 to start a rotational motion through the connecting column 12, and drive the spray pipe 5 to perform an angle adjustment on the front and rear sides with the help of the second support block 19. In this way, it is possible to perform targeted angle adjustment on the spray pipe 5 according to the actual specific requirements, improving the dust removal efficiency of the equipment and the convenience of equipment use.

[0035] Refer to Figure 4 - Figure 5 As shown in the figure, a water tank 2 is fixedly connected to the bottom of the bottom plate 8, a trolley 1 is fixedly connected to the bottom of the water tank 2, a plurality of conveying pipes 3 are fixedly connected to the outer wall of the spray pipe 5, the conveying pipes 3 are fixedly connected to the inside of the spray pipe 5, one end of each conveying pipe 3 is fixedly connected with an atomizing nozzle 4, a fan 6 is fixedly connected to the inside of the spray pipe 5, a filter screen 7 is arranged on one side of the fan 6, the outer wall of the filter screen 7 is fixedly connected to the inner wall of the spray pipe 5, an electric telescopic rod 21 is fixedly connected to the inside of the fixing block 20, a connecting plate 22 is fixedly connected to the output end of the electric telescopic rod 21, a fixing shell 24 is fixedly connected to the bottom of the connecting plate 22, a cleaning plate 25 is fixedly connected to the inside of the fixing shell 24, sliding strips 23 are slidably connected to both ends of the fixing shell 24, and both ends of the sliding strips 23 are fixedly connected to the outer wall of the fixing block 20.

[0036] Specifically, during the actual use of the spray dust suppression equipment, use the suction of the fan 6 to conduct the external air through the filter screen 7 into the inside of the spray pipe 5. At this time, start the electric telescopic rod 21. Use the output end of the electric telescopic rod 21 to drive the fixing shell 24 at the bottom of the connecting plate 22 to also start a synchronous movement. During the movement of the fixing shell 24, it will drive the cleaning plate 25 inside it to move up and down synchronously on the outer wall of the filter screen 7. During this process, use the sliding strips 23 to limit and guide the movement of the fixing shell 24, so as to ensure that the cleaning plate 25 inside the fixing shell 24 moves more stably. Using the up - and - down movement of the cleaning plate 25, it is possible to effectively clean the dust attached to the outer wall of the filter screen 7 comprehensively, thereby effectively preventing the situation of dust accumulation and blockage on the filter screen 7, improving the working efficiency of the equipment and ensuring the smooth operation of the equipment.

[0037] Working principle: During the use of the spray dust suppression equipment, start the first motor 9. The output end of the first motor 9 drives the connecting block 10 fixedly connected thereto to rotate. The rotation of the connecting block 10 drives the connecting ring 11 to rotate synchronously. During the rotation of the connecting ring 11, the spray pipe 5 is driven to perform left and right angle adjustment movements through the adjacent first support block 14 and second support block 19. When the angles on the front and back sides of the spray pipe 5 need to be adjusted, start the second motor 16. The output end of the second motor 16 drives the worm 18 fixedly connected thereto to rotate synchronously. The rotation of the worm 18 drives the worm gear 13 to start rotating synchronously. While rotating, the worm gear 13 drives the first support block 14 to start rotating through the connecting column 12, and drives the spray pipe 5 to perform angle adjustment on the front and back sides through the second support block 19, so as to perform targeted angle adjustment on the spray pipe 5 according to actual needs, improving the dust removal efficiency of the equipment. During the use of the spray dust suppression equipment, the fan 6 conducts the external air to the inside of the spray pipe 5 through the filter screen 7. At this time, start the electric telescopic rod 21. The up and down movement of the output end of the electric telescopic rod 21 drives the fixed shell 24 at the bottom of the connecting plate 22 to move synchronously. While moving, the fixed shell 24 drives the cleaning plate 25 to move up and down synchronously on the outer wall of the filter screen 7. The slide bar 23 is used to limit the movement of the fixed shell 24 to ensure that the movement of the cleaning plate 25 inside the fixed shell 24 is more stable. The up and down movement of the cleaning plate 25 sweeps the dust attached to the outer wall of the filter screen 7, effectively preventing the filter screen 7 from being blocked by dust and ensuring the smooth operation of the equipment.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
