Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing, and more specifically, to a dust suppression device for concrete sand and gravel aggregate processing. Background Art

[0002] A dust suppression device for concrete sand and gravel aggregate processing is a special equipment designed to solve the dust pollution problem generated during the processing of concrete sand and gravel aggregate. This device can effectively reduce the dust concentration in the air at the work site by using advanced dust suppression technology, thereby protecting the health of workers and improving the working environment, while also meeting environmental protection requirements. At present, many dust removal devices on the market have an obvious shortcoming in practical applications, that is, the angle adjustment of the suction end of the dust collection cylinder is completely dependent on manual operation, which has poor stability. Each adjustment requires the operator to rely on experience and personal feeling, so it is difficult to ensure that the angle of each adjustment is accurate. What is more troublesome is that for dust in different directions, it may take multiple attempts and angle adjustments to find the best dust removal position, which not only increases the complexity and time cost of the operation, but also greatly reduces the practicality and efficiency of the dust removal device.

At this time, the dust enters the dust reduction box 8 through the connecting hose 7 for filtration, thereby completing the left and right angle adjustment of the fan 5.

[0024] When using the dust suppression device, the fan 5 is continuously adjusted to the left and right angles, the motor 16 is turned on, the motor 16 drives the rotating shaft 29 to rotate, the rotating shaft 29 drives the half gear 18 to rotate inside the box 2, the teeth between the half gear 18 and the gear 19 are meshed, the half gear 18 drives the gear 19 to rotate, the water pipe 9 drives the rotating column 3 to rotate, the rotating column 3 drives the fan barrel 4 to rotate, and the fan barrel 4 drives the fan 5 to adjust to the left and right.

[0025] A dust suppression box 8 is fixedly installed inside the support plate 1, a motor 20 is fixedly installed on the top of the dust suppression box 8, a rotating shaft 24 is fixedly installed on one end of the motor 20, a gear 22 is fixedly installed on the top of the rotating shaft 24, the gear 22 is meshed with the teeth 23, a nozzle 21 is fixedly installed inside the teeth 23, and one end of the nozzle 21 is movably installed inside the water storage tank 10;

[0026] The water tank 10 is fixedly installed on the top of the dust reduction box 8, a water pipe 9 is fixedly installed on the top of the water tank 10, and one end of the water pipe 9 is connected to the bottom of the dust reduction box 8, a water pump 16 is fixedly installed inside the water pipe 9, a nozzle 21 is provided with a water spray port 25, and a filter plate 26 is fixedly installed inside the dust reduction box 8.

[0027] The staff turns on the fan 5, and the dust is sucked into the fan cylinder 4 through the fan 5, and then into the dust reduction box 8 through the connecting hose 7. At this time, the water pump 16 is turned on, and water is sucked into the water storage tank 10 at the bottom of the dust reduction box 8 through the water pipe 9, and the motor 20 is turned on. The motor 20 drives the rotating shaft 1 24 to rotate inside the support plate 1, and then drives the gear 2 22 to rotate through the rotating shaft 1 24. Through the meshing of the teeth between the gear 22 and the teeth 23, the gear 22 drives the teeth 23 to rotate, and the teeth 23 drives the nozzle 21 inside the water storage tank 10. Now the water inside the water storage tank 10 is quickly sprayed out into the dust reduction box 8 through the water nozzle 25, and the dust-containing water is filtered through the filter plate 26. The filtered water slowly flows into the dust reduction box 8 and is recycled again, thereby completing the dust reduction.

[0028] By turning on the fan 5, the dust is sucked into the fan cylinder 4 through the fan 5, and then the dust is discharged into the dust box 8 through the connecting hose 7. At this time, the water pump 16 is turned on, and water is sucked into the water storage tank 10 from the bottom of the dust box 8 through the water pipe 9. The motor 20 is turned on, and the motor 20 drives the rotating shaft 1 24 to rotate inside the support plate 1, and the rotating shaft 1 24 drives the gear 22 to rotate, and the teeth of the gear 22 and the teeth 23 are meshed, and the teeth 23 are driven to rotate by the gear 22, and the teeth 23 drive the nozzle 21 inside the water storage tank 10. Now the water inside the water storage tank 10 is quickly discharged through the water nozzle 25. The water sprayed out from the dust suppression box 8 and then filtered through the filter plate 26 contains dust. Compared with the traditional device, the device drives the nozzle 21 to rotate in the dust suppression box 8 through the cooperation between the teeth 23 and the gear 2 22, so that the water sprayed out from the water spray port 25 is evenly sprayed on the surface of the dust, so that the water and the dust are in full contact, which improves the efficiency of dust reduction, effectively improves the efficiency of dust reduction, reduces dust diffusion, and optimizes the dust reduction effect, making wet particles easier to settle. This contact also reduces the risk of secondary pollution and saves water resources. Finally, the working environment is significantly improved, the health of employees is protected, and the work efficiency and comfort are improved.

[0029] A support column 13 is fixedly installed at the bottom of the support plate 1 , and a universal wheel 14 is fixedly installed at the bottom of the support column 13 . The universal wheels 14 and the support columns 13 are arranged in groups of two, and there are four groups at the bottom of the support plate 1 .

[0030] Since the universal wheels 14 and the support columns 13 are grouped in pairs, there are a total of four groups at the bottom of the support plate 1. Through the cooperation between the support columns 13 and the universal wheels 14, the device can be easily moved. Moreover, the processing equipment may change position as the project progresses, and the dust reduction device can follow the movement, ensuring the effectiveness of dust control.

[0031] A handrail 12 is fixedly installed on the top of the support plate 1, and the handrail 12 is in a U-shape.

[0032] Since the handrail 12 is in a U-shape, the support column 13 and the universal wheel 14 can be moved by holding the handrail 12, which makes it more convenient for the staff to move the device and improves the transfer efficiency of the device.

[0033] A limiting groove 17 is provided inside the support plate 1 , and a tool box 15 is fixedly installed inside the limiting groove 17 .

[0034] By holding the tool box 15, the tool box 15 is slowly pushed into the limiting groove 17, and the tool box 15 is fixed by the limiting groove 17. The tool box 15 is usually equipped with tools and spare parts required for daily maintenance and repair of the dust reduction device, such as screwdrivers, wrenches, seals, etc. When the dust reduction device fails or needs regular inspection, the staff can quickly take out the required tools from the tool box and quickly perform repairs, thereby reducing downtime and improving production efficiency.

[0035] Among them, a motor protection cover 27 is fixedly installed on the outer surface of the motor 1 6, and a heat dissipation hole is opened on the outer surface of the motor protection cover 27. A support rod 28 is fixedly installed on the bottom of the motor protection cover 27, and the support rod 28 is in the form of a circular array.

[0036] Since the support rods 28 are arranged in a circular array at the bottom of the motor protection cover 27, the support rods 28 are supported by the motor protection cover 27, thereby ensuring the stability of the motor 6 during operation. At the same time, heat dissipation holes are opened inside the motor protection cover 27 to extend the service life of the motor 6.

[0037] A fixing bracket 11 is fixedly installed at the bottom of the water pipe 9, and the fixing bracket 11 presents two shapes of the same size.

[0038] Since the fixed bracket 11 presents two identically sized shapes at the bottom of the water pipe 9, the water pipe 9 is supported by the fixed bracket 11. Such stability ensures that the water pipe 9 can maintain its predetermined position and shape, thereby maintaining its normal function. At the same time, it can disperse and alleviate these stresses, reduce the risk of damage to the water pipe 9, and extend its service life.

[0039] The working principle and use process of this utility model:

[0040] When using the dust reduction device, the staff continuously adjusts the angle of the fan 5 to the left and right, turns on the motor 6, and drives the rotating shaft 29 to rotate through the motor 6, and then drives the half gear 18 to rotate inside the box body 2 through the rotating shaft 29, and then drives the gear 19 to rotate through the meshing of the teeth between the half gear 18 and the gear 19, and then drives the rotating column 3 to rotate through the water pipe 9, and then drives the fan barrel 4 to rotate through the rotating column 3, and then drives the fan 5 to adjust to the left and right through the fan barrel 4, and the dust is sucked into the interior of the connecting hose 7 through the fan 5. At this time, the dust enters the dust reduction box 8 through the connecting hose 7 for filtration, thereby completing the left and right angle adjustment of the fan 5.

[0041] The staff turns on the fan 5, and the dust is sucked into the fan cylinder 4 through the fan 5, and then into the dust reduction box 8 through the connecting hose 7. At this time, the water pump 16 is turned on, and water is sucked into the water storage tank 10 at the bottom of the dust reduction box 8 through the water pipe 9, and the motor 20 is turned on. The motor 20 drives the rotating shaft 1 24 to rotate inside the support plate 1, and then drives the gear 2 22 to rotate through the rotating shaft 1 24. Through the meshing of the teeth between the gear 22 and the teeth 23, the gear 22 drives the teeth 23 to rotate, and the teeth 23 drives the nozzle 21 inside the water storage tank 10. Now the water inside the water storage tank 10 is quickly sprayed out into the dust reduction box 8 through the water nozzle 25, and the dust-containing water is filtered through the filter plate 26. The filtered water slowly flows into the dust reduction box 8 and is recycled again, thereby completing the dust reduction.
