Description

Technical Field

[0001] The invention relates to the technical field of environmental protection dust removal, in particular to a dust removal device for environmental protection engineering. Background Art

[0002] In dusty environments, dust removal is usually achieved by spraying water mist. Existing dust removal equipment usually installs a water tank on a cart, and then installs a nozzle on the cart to spray the water in the water tank. In order to increase the spraying range, it is usually necessary to drive the nozzle to swing up and down when spraying water. When the nozzle swings upward, the water spraying range can be increased. As the water spraying range increases, the range that requires dust removal will also increase, so the nozzle needs to spray more water. When the nozzle swings downward, dust will be removed in the nearby range, and the dust removal range will be reduced. Therefore, the nozzle needs to spray less water, and the existing nozzle cannot change the water spraying amount, which will result in insufficient water when the nozzle increases the water spraying range and fails to achieve the desired dust removal effect, or too much water when the nozzle reduces the water spraying range, resulting in a waste of water resources.

[0036] When working, by driving the rotating rods 25 on the front and rear sides to rotate back and forth at the same time, the rotating rod 25 drives the first slider 27 on one side to move downward and the first slider 27 on the other side to move upward through the two first slide grooves 26, and the first slider 27 moving downward will drive the piston rod 24 connected thereto to move downward, and the piston rod 24 will drive the piston 23 to move downward when it moves downward, and when the piston 23 moves downward, the first one-way valve 21 in the water pump 18 corresponding to the piston 23 opens, and at this time, the water in the water tank 4 will enter the water pump 18 through the first water pipe 19; when the rotating rod 25 starts to rotate in the opposite direction, the first slider 27 at the lower position will be pushed to move upward , the first slider 27 moving upward will drive the piston rod 24 connected thereto to move upward, and the piston rod 24 moving upward will drive the piston 23 connected thereto to move upward, at this time, the second one-way valve 22 in the water pumping cylinder 18 is opened, and the first one-way valve 21 is closed, and the water in the water pumping cylinder 18 will pass through the second one-way valve 22 and enter the connecting pipe 16 through the second water pipe 20, and then be sprayed out through the nozzle 6; because when the rotating rod 25 rotates, the pistons 23 in the two water pumping cylinders 18 move upward and downward respectively, and at this time, the piston 23 moving upward will push the water in the corresponding water pumping cylinder 18 into the nozzle 6, thereby ensuring that the nozzle 6 can continuously spray water.

When the sliding rod 32 slides left and right, it will drive the sliding frame 36 connected thereto to move left and right. Since the sliding frame 36 is sleeved on the fixed rod 35, the sliding frame 36 will drive the half gear 34 to rotate back and forth continuously through the fixed rod 35, and the half gear 34 will drive the rotating rod 25 to rotate back and forth.

[0040] like Figure 6-Figure 9 As shown, as a further solution of the present invention, the adjustment mechanism includes two third support frames 37, the two third support frames 37 are symmetrically distributed at the front and rear sides of the second support frame 17, and the two third support frames 37 are fixedly connected to the support plate 1; a third slide groove 38 is provided on the third support frame 37, and a second slider 39 is slidably connected in the third slide groove 38, and the second sliders 39 on the front and rear sides are respectively fixedly connected to the driving frames 28 on the front and rear sides; a fixing ring 40 is provided at the bottom position of the turntable 9, and the fixing ring 40 is fixedly connected to the driving frames 28 on the front and rear sides; a lifting mechanism is provided on the fixing ring 40, and the lifting mechanism is used to drive the two driving frames 28 to slide up and down when the nozzle 6 swings up and down;

When the rotating ring 41 moves upward, it will drive the fixed ring 40 to move upward. The fixed ring 40 drives the driving frames 28 on the front and rear sides to move upward. When the driving frame 28 moves upward, it will drive the sliding frame 36 to move upward. At this time, the sliding frame 36 will be closer to the center of the half gear 34.
