Description

Technical Field

[0001] The present invention relates to the technical field of spray dust removal devices, and particularly to a controllable spray dust removal device for building construction. Background Technique

[0002] A spray dust removal device is a device used to reduce dust particles in the air. By spraying water through nozzles into tiny water droplets, these water droplets collide and come into contact with dust particles in the air, causing the dust particles to be adsorbed or wrapped by the water droplets, forming larger particle clusters, which settle to the ground or other surfaces due to gravity, thereby achieving the purpose of reducing the dust concentration in the air.

[0003] The patent with the application number 202420432086.4 relates to a controllable spray dust removal device for building construction, which particularly includes a water storage tank. A cleaning tank is fixedly connected to the left side surface of the water storage tank. A high-pressure air pump is fixedly connected to the inner wall of the cleaning tank. An air suction pipe is fixedly connected to the input end of the high-pressure air pump, and an air outlet pipe is fixedly connected to the output end of the high-pressure air pump. A rectangular groove is opened on the left side surface of the water storage tank. A telescopic rod is fixedly connected to the inner wall of the water storage tank. The telescopic end of the telescopic rod is fixedly connected to a connecting plate. A filter plate is fixedly connected to the outer surface of the connecting plate. The outer surface of the filter plate is slidably connected to the inside of the rectangular groove. By operating the high-pressure air pump, the air suction pipe can draw external air into the high-pressure air pump, and the air can be blown out through the air outlet pipe, so as to perform high-pressure air inflation cleaning on the upper filter plate, avoiding the problem that the filter plate used to filter water needs to be regularly taken out and cleaned by workers when the device is in use. However, the dust removal area of this device during building construction dust removal is small, and the height of dust removal cannot be adjusted, resulting in a low dust removal effect.

The slider 713 drives the articulated rod 714 to move through the hinge point. The articulated rod 714 drives the machine housing 72 to move through the hinge point. The machine housing 72 drives the spraying pipeline 78 to move. The spraying pipeline 78 drives the rotary nozzle 79 to adjust the height. While adjusting, the movement of the machine housing 72 drives the telescopic support 71 to move to limit the machine housing 72, avoiding a smaller dust reduction area during dust reduction, making the dust reduction range better, enabling the device to be applicable to more working places, improving the space utilization rate while achieving a good dust removal effect.

[0015] The protection mechanism 8 includes a positioning block 81, a protection shell 82, a buckle 83, and a clamping block 84. The positioning block 81 is fixedly connected to the front side of the vehicle shell 1.

The buckle 83 is rotatably connected to the inner wall of the right protection shell 82. The clamping block 84 is rotatably connected to the inner wall of the right protection shell 82 through a torsion spring. After the dust reduction is completed, the staff closes the protection shell 82. After closing, the buckle 83 is manually rotated. The rotation of the buckle 83 drives the clamping block 84 to rotate by contacting the outer surface with the clamping block 84. The clamping block 84 locks the buckle 83 through the torsion spring, preventing dust from adhering to the nozzle when the rotary nozzle 79 is not in use, resulting in the blockage of the spraying port, further improving the service life of the equipment, avoiding damage to the rotary nozzle 79 by foreign objects, saving the maintenance and cleaning costs of the equipment. The protection mechanism 8 also includes a convex block 85, a moving block 86, a sliding plate 87, and a knocking block 88.

The moving block 86 is fixedly connected to the outer surface of the sliding plate 87. The knocking block 88 is fixedly connected to the side of the sliding plate 87 away from the moving block 86.

The sliding plate 87 drives the knocking block 88 to move. When the convex block 85 leaves, the sliding plate 87 drives the knocking block 88 to reset through the spring and knock on the rotary nozzle 79, preventing impurities from blocking the spraying port during spraying, resulting in a reduction in the spraying area, making the spraying smoother and more stable, improving the service life of the nozzle, and also improving the overall dust reduction effect of the equipment.

[0016] Working principle: When the device is not in use, it is charged and energy-stored by the solar cell panel 11. When in use, water is supplied to the water tank 6 by the staff connecting to the water inlet pipe 12. When starting the device, water is filled into the casing 72 through the telescopic pipe 10. Before spraying, the staff manually rotates the turntable 711. The rotation of the turntable 711 drives the rotation of the threaded rod 712. The rotation of the threaded rod 712 moves through the slider 713 in the thread groove. The slider 713 drives the articulated rod 714 to move through the hinge point. The articulated rod 714 drives the casing 72 to move through the hinge point. The casing 72 drives the spraying pipe 78 to move. The spraying pipe 78 drives the rotary nozzle 79 to adjust the height. While adjusting, the movement of the casing 72 drives the telescopic bracket 71 to move to limit the casing 72, avoiding a smaller dust reduction area during dust reduction, making the dust reduction range better, enabling the device to be applicable to more working places, improving the space utilization rate and achieving a good dust removal effect at the same time. After adjusting the spraying pipe 78, the staff starts the motor 73 to work. The work of the motor 73 drives the rotation of the rotating shaft 74. The rotating shaft 74 drives the fan 75 to start rotating to break up the water. The small water droplets broken up by the fan 75 are more likely to capture the fine particulate dust floating out from the mixing plant, thereby improving the capture efficiency of fine dust. At the same time, the rotating shaft 74 drives the first column gear 77 to rotate. The first column gear 77 drives the second column gear 710 to rotate through the engagement of the circumferential surface with the second column gear 710. The second column gear 710 drives the rotary nozzle 79 to rotate for spraying, and can spray the surrounding and upper space of the stacking yard without dead angles, reducing the impact of dust on the surrounding environment and staff, and improving the overall dust reduction effect of the equipment.

[0017] After the dust reduction is completed, the staff closes the protective shell 82. After closing, by manually rotating the buckle 83, the rotation of the buckle 83 drives the rotation of the block 84 through the contact of the outer surface with the block 84. The block 84 locks the buckle 83 through the torsion spring, avoiding dust adhering to the nozzle when the rotary nozzle 79 is not in use, resulting in the blockage of the spraying port, further improving the service life of the equipment, and also avoiding the damage of foreign objects to the rotary nozzle 79, saving the maintenance and cleaning costs of the equipment. During the rotary dust reduction, the rotation of the rotary nozzle 79 drives the convex block 85 to rotate. The rotation of the convex block 85 drives the moving block 86 to displace through the outer surface. The moving block 86 drives the sliding plate 87 to move. The sliding plate 87 drives the knocking block 88 to move. When the convex block 85 leaves, the sliding plate 87 drives the knocking block 88 to reset through the spring to knock the rotary nozzle 79, avoiding impurities blocking in the spraying port during spraying, resulting in a reduction in the spraying area, making the spraying smoother and more stable, improving the service life of the nozzle, and also improving the overall dust reduction effect of the equipment.

While knocking on the nozzle, the knocking block 88 reciprocates and drives the pulley 97 to rotate through the top contact surface. The pulley 97 drives the reciprocating lead screw 98 to rotate. The reciprocating lead screw 98 drives the telescopic scraping rod 99 to reciprocate through the reciprocating chute to scrape the inner wall of the nozzle, avoiding the accumulation of debris in the spray holes, making the spraying area better, improving the dust removal effect of the device, reducing manual cleaning, and making the service life of the device longer.
