Description

Technical Field

[0001] The present application relates to the technical field of dust suppression, and in particular to a dust suppression device for civil engineering. Background Art

[0002] In civil engineering construction, in order to reduce dust pollution in the air and protect the environment and the health of construction workers, dust suppression equipment is used to effectively suppress dust in the air. Spray dust suppression equipment and suction dust suppression equipment are the two most common types of dust suppression equipment.

[0003] The dust reduction principle of spray dust reduction equipment is to convert water into water mist through an atomizing nozzle and spray it into the air, so that the water mist contacts the dust particles in the air and adheres to the dust particles, increasing their weight and gradually sinking to the ground under the action of gravity, thereby achieving the effect of dust reduction; the dust reduction principle of suction dust reduction equipment is to generate negative pressure suction through motor drive, inhale the external dust-containing gas, physically filter the dust and purify the air inside the equipment, effectively remove and isolate the dust and pollutants in the air, thereby achieving the effect of dust reduction;

[0004] Existing spray dust suppression equipment often requires continuous dust suppression work when used in civil engineering construction. Continuous water mist spraying consumes a lot of water resources, and excessive spraying can easily lead to water accumulation on the ground, which in turn affects material storage or personnel walking safety. The dust raised during civil engineering construction often contains large particles of gravel or soil. Large particles of gravel or soil can cause rapid wear of the suction port of the suction dust suppression equipment, and easily clog the pipes and filtration system, affecting the dust suction and dust reduction efficiency. In order to solve the above problems, a dust suppression device for civil engineering is proposed.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0024] It should be noted that a connecting plate 4 is provided between the dust hood 3 and the anti-blocking filter 5 to connect the two.

[0025] It should be further explained that the anti-blocking filter 5 is tilted counterclockwise from top to bottom, and the tilt angle is 20-40 degrees counterclockwise;

[0026] By adopting the above technical solution, when dust reduction is needed, the negative pressure fan 9 is started to suck in the dust outside the equipment body 1. The large particles of gravel or dust in the dust are filtered by the anti-blocking filter 5 and fall to the ground through the stone drop port 18 along the inclined surface of the anti-blocking filter 5 under the action of their own gravity. The fine dust is gathered by the dust hood 3 and enters the equipment body 1 through the dust suction pipe 2. The spray component is started to spray the dust on the equipment body 1 to make it settle on the filter discharge component. After the settled dust is filtered, the air is discharged to the outside of the equipment body 1 again.

[0027] Reference Figure 1 , the anti-blocking filter 5 is provided with a cleaning component for cleaning the mesh;

[0028] The cleaning assembly includes a cleaning brush 6, a motor 7, and a rotating block 8. The rotating block 8 rotates on the anti-blocking filter 5. The cleaning brush 6 and the anti-blocking filter 5 are slidably arranged. The cleaning brush 6 is fixed on the rotating block 8. The motor 7 is fixed on the anti-blocking filter 5. The rotor end of the motor 7 is connected to the rotating block 8.

[0029] It should be noted that the cleaning brush 6 is fixed on the central axis of the rotating block 8 and rotates coaxially with the rotating block 8. A slide groove is provided at one end of the cleaning brush 6, and the edge of the anti-blocking filter 5 is gap-matched with the slide groove on the cleaning brush 6;

[0030] By adopting the above technical solution, in order to prevent large particles of gravel and dust from clogging the anti-blocking filter 5, when vacuuming, the motor 7 can be started to rotate the rotating block 8, thereby driving the cleaning brush 6 to slide along the edge of the anti-blocking filter 5, thereby cleaning the mesh surface and avoiding clogging of the mesh surface.

[0031] Reference Figure 1 The spray assembly includes a connecting pipe 10, a water tank 11, and an atomizing nozzle 14. The water tank 11 is fixed on the equipment body 1. The water tank 11 is connected to the inner cavity of the equipment body 1 through the connecting pipe 10. The atomizing nozzle 14 is circumferentially arranged at one end of the connecting pipe 10 and is located in the equipment body 1.

[0032] It should be noted that the model of the atomizing nozzle 14 can refer to the SPJT-SS spiral nozzle;

[0033] It should be further explained that the connecting pipe 10 is also provided with a valve for controlling the spraying amount, which may be a solenoid valve (not shown in the figure). When the solenoid valve is energized, the valve is opened, and when the solenoid valve is de-energized, the valve is closed.

[0034] By adopting the above technical solution, when dust enters the equipment body 1, the solenoid valve is energized and opened, so that the spray liquid in the water tank 11 is sprayed into the equipment body 1 through the atomizing nozzle 14. The end of the dust suction pipe 2 is slightly lower than the spraying height of the atomizing nozzle 14, so that the atomizing nozzle 14 can fully cover the dust in the equipment body 1. After the spraying is completed, the solenoid valve is powered off and closed.

[0035] Reference Figure 1 The filter and discharge assembly includes a filter plate 15, an exhaust fan 16, and an air outlet 17. The filter plate 15 is located in the device body 1, the exhaust fan 16 is located below the filter plate 15, the air outlet 17 is located at the bottom of the outer wall of the device body 1 and is arranged in a plurality of directions. The air outlet 17 is located below the filter plate 15;

[0036] It should be noted that the filter plate 15 may be an activated carbon plate, and the device body 1 is also provided with a cleaning port (not shown in the figure) for replacing or cleaning the filter plate 15;

[0037] By adopting the above technical solution, the dust after spraying settles onto the filter plate 15 under the action of gravity, and the exhaust fan 16 is started to accelerate the settling speed of the dust in the equipment main body 1. At the same time, after the dust is filtered on the filter plate 15, the air in the equipment main body 1 is discharged outside the equipment main body 1 through the air outlet 17.

[0038] Reference Figure 1-2 The equipment body 1 is also provided with a circulation component for circulating the spray liquid in the water tank 11. The circulation component is arranged on the equipment body 1. The circulation component includes a circulation water pipe 12 and a water pump 13.

The end of the circulation water pipe 12 close to the water tank 11 is provided with a water pump 13.

[0039] It should be noted that the port where the circulating water pipe 12 is connected to the water tank 11 is located below the air outlet 17;

[0040] By adopting the above technical solution, after the dust is sprayed, the dust is filtered on the filter plate 15, and the excess spray liquid will flow to the bottom of the equipment body 1 through the filter plate 15. When the spray liquid at the bottom of the equipment body 1 is collected to a port connected to the equipment body 1 that is higher than the circulating water pipe 12, the water pump 13 can be started to circulate the filtered spray liquid into the water tank 11, thereby recycling the spray liquid and saving a certain amount of water resources.

[0041] The implementation principle of a dust suppression device for civil engineering in an embodiment of the present application is as follows: when dust suppression is needed, the negative pressure fan 9 is started to suck in the dusty air outside the equipment main body 1, and the large particles of gravel and dust in the dust are filtered by the anti-blocking filter 5, and fall to the ground through the rock drop port 18 along the inclined surface of the anti-blocking filter 5 under their own gravity, and the fine dust is sucked into the equipment main body 1, and the dust in the equipment main body 1 is sprayed by the atomizing nozzle 14. After sufficient spraying, the exhaust fan 16 is started to accelerate the dust to settle on the filter plate 15. After the dust is filtered by the filter plate 15, the clean air is discharged outside the equipment main body 1 through the air outlet 17 under the action of the exhaust fan 16, and the excess spray liquid flows into the bottom of the equipment main body 1, and can be pumped into the water tank 11 by the water pump 13 for recycling, and the filter plate 15 can be replaced or cleaned through the cleaning port, and the dust suppression work is completed.
