Description

Technical Field

[0001] The invention relates to the technical field of environmental dust removal, and specifically discloses a dust removal device for air pollution control in environmental engineering. Background Art

[0002] Environmental protection refers to human beings solving real or potential environmental problems, coordinating the relationship between humans and the environment, and preventing the natural environment from being polluted and destroyed. In order to protect the natural environment, dust suppression devices are needed to reduce dust in the environment when transforming the environment.

[0003] Most of the existing dust suppression devices use sprinkler trucks or dust removal fog cannons to perform dust suppression work. When using sprinkler trucks or dust removal fog cannons to perform environmental dust suppression spraying work, electric push rods and other devices are often used to adjust the angle of the nozzle. Since the adjustment range of electric push rods and other devices is large, the accuracy and stability of environmental dust suppression spraying are low, which affects the work efficiency.

[0004] To solve the above problems, a Chinese patent with publication number CN218358196U discloses a spray device for environmental dust reduction, including a base and an adjusting mechanism; the base: a water tank is arranged on the left side of its upper end, a water supply port arranged on the upper end of the water tank is connected to the lower end of a water supply pipe, a water supply gate is connected in series in the middle of the water supply pipe, mounting seats are arranged on the right side of the upper end of the base, a mounting frame is rotatably connected between the mounting seats through a rotating shaft, the top wall and the bottom wall of the mounting frame are rotatably connected to the mounting frame through a pin shaft, nozzles are arranged at the upper and lower ends of the inner wall of the right end of the mounting frame, and mounting holes are arranged at the four corners of the lower end of the base; the adjusting mechanism is arranged inside the mounting frame, and the spray device for environmental dust reduction realizes the angle of the nozzle through the coordinated arrangement of the swing rod, thereby improving the accuracy and stability of environmental dust reduction spraying and improving the work efficiency.

[0005] The above device has the following problems during actual use: the number of water spraying holes of the nozzle cannot be adjusted during the water spraying period, so the pressure and range of the water spraying cannot be changed. As a result, when water is sprayed from the nozzle holes, the spraying method is relatively simple, and the effective distance of the water is relatively fixed, which leads to a limited range of contact between water and dust, reduces the utilization rate of water, and cannot ensure that the water can fully and comprehensively reduce dust, and has poor practicality. Summary of the invention

[0006] The invention provides a dust removal device for air pollution control in environmental engineering, so as to solve the problem that the existing spraying device cannot adjust the effective distance when the spray hole sprays water.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a dust removal device for air pollution control in environmental engineering, comprising a movable base, a lifting column, and a water tank, wherein the lifting column is fixedly connected to the base, the water tank is connected to the lifting column, and further comprises a connecting cylinder with a bottom opening, a water guide cylinder with a top opening, a hollow plate, an adjustment mechanism symmetrically arranged on both sides of the water guide cylinder along the axial direction of the water guide cylinder, and a driving mechanism for driving the hollow plate to rotate; the connecting cylinder is connected to the water tank; the water guide cylinder is fixedly connected to the lifting column; the hollow plate is fixedly connected to the water guide cylinder, the hollow plate is rotatably connected to the connecting cylinder, and both ends of the hollow plate They are respectively connected with the connecting tube and the water guide tube; the adjusting mechanism includes a nut seat, an adjusting assembly symmetrically arranged on both sides of the nut seat along the length direction of the nut seat, and a power assembly used to drive the nut seat to reciprocate along the axial direction of the water guide tube; the adjusting assembly includes an adjusting plate, a plurality of spray hole groups equidistantly opened on the water guide tube along the axial direction of the water guide tube, and a moving part used to drive the adjusting plate to reciprocate along the height direction of the nut seat; the adjusting plate is slidably connected to the nut seat; the spray hole group includes a plurality of spray holes equidistantly arranged along the circumferential direction of the water guide tube, and the spray holes are located on the movement trajectory of the adjusting plate.

[0008] The principles and advantages of this solution are:

[0009] 1. Water is introduced into the water guide cylinder through the water tank so that the water can be sprayed out through the spray hole. After the water is sprayed out from the spray hole, it can mix with the dust dispersed in the air, thereby achieving dust reduction in the air and reducing the amount of dust dispersed in the air, that is, reducing the pollution of dust to the environment and the harm to the human body.

[0010] During the water spraying from the spray hole, the hollow plate is driven to rotate by the driving mechanism. During the rotation of the hollow plate, the water guide cylinder rotates synchronously. During the rotation of the water guide cylinder, the water guide cylinder has a certain centrifugal force, so that the water sprayed from the spray hole can move in a circumferential direction. During the circumferential movement of water, the water's action range can be expanded, so that the contact area between water and dust is more sufficient, thereby enhancing the contact effect between water and dust, improving the utilization rate of water, and ensuring that dust can be more completely removed.

[0011] 2. When the water is sprayed out through the spray hole, the moving part drives the adjustment plate to reciprocate along the height direction of the nut seat. When the adjustment plate reciprocates toward the position of the spray hole, the adjustment plate can push the water to spray out, thereby enhancing the force of the water spraying, making the water's action distance farther and the action range wider, accelerating the dust reduction speed and shortening the dust reduction time.

[0012] Furthermore, when the adjustment plate moves toward the position where the spray holes are located, the power assembly drives the adjustment plate to move closer to or farther from the position where the hollow plate is located, so that each time the adjustment plate moves closer to the position where the spray holes are located, the number of spray holes that the adjustment plate can act on is different. When the number of spray holes spraying water decreases, the pressure in the water guide tube will increase, so that the distance at which the water can act is farther. When the number of spray holes spraying water increases, the pressure in the water guide tube will decrease, so that the distance at which the water can act is restored to the initial state. Through the above movement, by adjusting the number of spray holes, the distance at which the water can act can be changed from near to far or from far to near, thereby ensuring that the water can comprehensively reduce the dust dispersed in the air, further improving the utilization rate of water, and enhancing the effect of water.

[0013] Furthermore, a hollow rubber block is fixedly connected to the adjustment plate.

[0014] The hollow rubber block is provided so that when the regulating plate pushes the water out, a negative pressure environment will be formed between the regulating plate and the inner wall of the water guide tube, so that the water can be sprayed farther and have a wider range under the action of negative pressure, and can come into contact with the dust dispersed in the air more fully, thereby further improving the efficiency of the water action.

[0015] Furthermore, the adjustment component also includes an adjustment part; the adjustment part includes a first guide block, a moving block, a side block, a plurality of adjustment units equidistantly arranged along the length direction of the side block, and a driving unit for driving the moving block to reciprocate along the length direction of the first guide block; the first guide block is fixedly connected to the outer wall of the water guide cylinder; the moving block is slidingly connected to the first guide block; the side block is fixedly connected to the moving block; the adjustment unit includes an adjustment rod, a plurality of conical blocks equidistantly arranged along the length direction of the adjustment rod; the adjustment rod is fixedly connected to the side block; the conical block is fixedly connected to the adjustment rod, and the spray hole is located on the movement trajectory of the conical block.

[0016] During the water spraying from the spray hole, the cone block can continuously move toward the position close to the spray hole under the drive of the driving unit. During the movement of the cone block, the cone block can extend into the spray hole, thereby reducing the diameter of the water spray in the spray hole and increasing the pressure in the spray hole, so that the water sprayed from the spray hole has a stronger force under the action of the cone block. After the force of the water spray is enhanced, the water can act at a farther distance and over a wider range, which ensures that the water can come into contact with more dust in the air and speeds up the dust reduction process. In addition, after the force of the water is enhanced, the water can also disperse the dust dispersed in the air, reducing the probability of dust agglomeration.

[0017] During the vertical reciprocating motion of the adjusting rod, the adjusting rod can disperse the water sprayed from the spray hole, so that the water will be dispersed into a number of water droplets. After the water is dispersed into water droplets, the range of water action will be further expanded, so that the water can contact the dust more fully and comprehensively.

[0018] Furthermore, the adjustment component also includes a diffusion part; the diffusion part includes a side plate, a first screw, a first guide rod, a plurality of diffusion units equidistantly arranged along the axial direction of the first screw, and a power unit for driving the first screw to rotate; the side plate is fixedly connected to the outer wall of the water guide cylinder; the first screw is rotatably connected to the side plate; the first guide rod is fixedly connected to the side plate; the diffusion unit includes a movable block and a diffusion block; the movable block is rotatably connected to the first screw, and the movable block is slidably connected to the first guide rod; the diffusion block is fixedly connected to the movable block, and the diffusion block is located above the adjustment rod.

[0019] After the water is dispersed under the vertical action of the plurality of adjusting rods, it reciprocates along the length direction of the first guide rod through the plurality of diffusion blocks, so that the plurality of diffusion blocks can further disperse the water droplets after the adjustment rods act, that is, the water droplets can be dispersed into a plurality of water droplets with smaller particle sizes. Through the above movement, the contact area between the water droplets and the dust can be increased, ensuring that the water droplets and the dust contact more fully and thoroughly, and further improving the utilization rate of the water droplets.

[0020] To sum up, under the vertical action of the adjusting rod and the lateral action of the diffusion block, the water can be broken up into several water droplets with smaller particle sizes, and then the dust can be reduced by the water droplets, which can further enhance the dust reduction effect, improve the dust reduction efficiency, and ensure the dust reduction quality.

[0021] Furthermore, it also includes an auxiliary part symmetrically arranged on both sides of the water guiding cylinder along the axial direction of the water guiding cylinder; the auxiliary part includes an auxiliary frame, a piston cylinder, a piston block, an air pipe, a derivation unit symmetrically arranged on both sides of the piston cylinder along the width direction of the piston cylinder, and a motion unit used to drive the piston block to reciprocate along the length direction of the piston cylinder; the auxiliary frame is fixedly connected to the outer wall of the water guiding cylinder; the piston cylinder is fixedly connected to the outer wall of the water guiding cylinder; the piston block is slidably connected to the piston cylinder; the air pipe is connected to the piston cylinder; the derivation unit includes an auxiliary pipe, a conduit, and a plurality of guide holes equidistantly opened on the conduit along the length direction of the conduit; and the two ends of the auxiliary pipe are respectively connected to the piston cylinder and the conduit.

[0022] After the water is broken into several water droplets, the piston block and the piston cylinder cooperate with each other to continuously eject compressed air from the guide hole. During the ejection of compressed air, the compressed air has a certain force, and the compressed air can act on the water droplets. That is, with the assistance of compressed air, the water droplets can enhance the force of the water droplets when ejected, expand the range of the water droplets, and further enhance the dust reduction effect of the water droplets on the dust, which promotes a more comprehensive and complete contact between the water droplets and the dust, and accelerates the progress of dust reduction.

[0023] Furthermore, it also includes auxiliary units symmetrically arranged on both sides of the auxiliary frame along the length direction of the auxiliary frame; the auxiliary unit includes a second guide block, a slider, a fixed block, an extrusion plate, and an auxiliary part for driving the slider to reciprocate along the length direction of the second guide block; the second guide block is fixedly connected to the outer wall of the water guide cylinder; the slider is slidably connected to the second guide block; the fixed block is fixedly connected to the slider; the extrusion plate is fixedly connected to the fixed block, and the conduit is a rubber tube, which is located on the movement trajectory of the extrusion plate.

[0024] The extrusion plate can make vertical reciprocating motion under the action of the auxiliary parts, so that the extrusion plate can continuously squeeze the conduit, that is, the conduit will continuously deform. During the deformation of the conduit, the pressure inside the conduit will increase, and the force of the compressed air ejected from the guide hole can be further increased. After the force of the compressed air increases, the movement speed of the water droplets can be further accelerated, the range of action of the water droplets can be increased, the utilization rate of the water droplets is improved, and the water droplets can be more efficiently dusted.

[0025] Furthermore, it also includes a linkage part symmetrically arranged on both sides of the water guiding tube along the axial direction of the water guiding tube; the linkage part includes a swing frame and a linkage unit symmetrically arranged on both sides of the limit frame along the length direction of the limit frame; the swing frame is hinged to the limit frame; the linkage unit includes a second screw rod, a second guide rod, a side block, a swing block, and a linkage part for driving the second screw rod to rotate; the second screw rod is rotationally connected to the side plate; the second guide rod is fixed to the side plate; the side block is threadedly connected to the second screw rod, and the side block is slidably connected to the second guide rod; the two ends of the swing block are respectively hinged to the side block and the swing frame.

[0026] The swing block makes reciprocating motion along the length direction of the second guide rod, thereby enabling the swing block to drive the swing frame to swing back and forth. During the swinging of the swing frame, the movement path of the water droplets can be changed, so that the water droplets will be sprayed from different directions, that is, the diffusion range of the water droplets when sprayed will be further expanded, and the water droplets can be diffused over a large area, so that the dust reduction area of ​​the water droplets is more sufficient and complete, thereby further improving the utilization rate of the water droplets, enhancing the dust reduction effect, and ensuring the dust reduction quality.

[0027] Furthermore, the driving mechanism includes a rotating shaft, a connecting rod, and a driving member for driving the rotating shaft to rotate; the rotating shaft is rotatably connected to the connecting cylinder; and both ends of the connecting rod are fixedly connected to the rotating shaft and the hollow plate respectively.

[0028] The driving member drives the rotating shaft to rotate, and during the rotating shaft rotation, the connecting rod rotates synchronously. During the rotating shaft rotation, the connecting rod rotates synchronously, and during the rotating hollow plate rotation, the water guide cylinder rotates synchronously.

[0029] Furthermore, the power assembly includes a third screw, a third guide rod, and a power unit for driving the third screw to rotate; the third screw is rotatably connected to the hollow plate; the third guide rod is fixed to the hollow plate; the nut seat is threadedly connected to the third screw, and the nut seat is slidably connected to the third guide rod.

[0030] The third screw rod is driven to rotate by the power unit, and during the rotation of the third screw rod, the nut seat can perform reciprocating motion along the length direction of the guide rod.

[0031] Furthermore, it also includes a moving part symmetrically arranged on both sides of the water guide tube along the axial direction of the water guide tube; the moving part includes a driving shaft, a first gear, and a first rack; the driving shaft is rotatably connected to the nut seat; the first gear is fixed to the driving shaft; the first rack is fixed to the hollow plate, and the first gear is meshed with the first rack; the moving part includes a first cam and a first spring; the first cam is fixed to the driving shaft, and the first cam is against the adjustment plate; the two ends of the first spring are respectively connected to the adjustment plate and the nut seat.

[0032] When the nut seat reciprocates along the length direction of the third guide rod, the drive shaft moves synchronously. When the drive shaft moves, the first gear moves synchronously. When the first gear moves, the first gear is engaged with the first rack, so the first gear rotates. When the first gear rotates, the drive shaft rotates synchronously, so the drive shaft can rotate while reciprocating along the length direction of the third guide rod.

[0033] During the rotation of the drive shaft, the first cam rotates synchronously. During the rotation of the first cam, when the protrusion of the first cam abuts against the adjustment plate, the adjustment plate moves to a position close to the spray hole, and the first spring is compressed. When the protrusion of the first cam no longer abuts against the adjustment plate, the first spring drives the adjustment plate to reset, and the adjustment plate moves to a position away from the spray hole. Therefore, the adjustment plate can continuously approach or move away from the spray hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] Specific implementation process:

[0067] The water is introduced into the water guide tube 5 by the water pump in the water tank 3, so that the water can flow in the connecting tube 4 and the water guide tube 5, and finally the water is sprayed out through the spray hole 9. After the water is sprayed out from the spray hole 9, the water can be mixed with the dust dispersed in the air, thereby achieving dust reduction in the air, reducing the amount of dust dispersed in the air, that is, reducing the pollution of the environment by the dust and the harm to the human body.

[0068] During the water spraying from the spray hole 9, the motor is started, and the output shaft of the motor drives the rotating shaft 37 to rotate. During the rotation of the rotating shaft 37, the hollow plate 6 rotates synchronously. During the rotation of the hollow plate 6, the water guide tube 5 rotates synchronously. During the rotation of the water guide tube 5, the water guide tube 5 has a certain centrifugal force, so that the water sprayed from the spray hole 9 can move circumferentially. During the circumferential movement of water, the scope of action of water can be expanded, so that the contact area between water and dust is more sufficient, thereby enhancing the contact effect between water and dust, improving the utilization rate of water, and ensuring that dust can be more completely reduced.

[0069] During the circumferential movement of the water guide tube 5, the third screw rod 40 moves synchronously. During the movement of the third screw rod 40, the fourth gear 54 moves synchronously. During the circumferential movement of the fourth gear 54, when the fourth gear 54 is meshed with the first arc-shaped rack 52, the fourth gear 54 is not meshed with the second arc-shaped rack 53, and the fourth gear 54 rotates forward; when the fourth gear 54 is meshed with the second arc-shaped rack 53, the fourth gear 54 is not meshed with the first arc-shaped rack 52, and the fourth gear 54 rotates reversely. Therefore, under the action of the fourth gear 54, the third screw rod 40 can rotate while performing circumferential movement.

[0070] During the rotation of the third screw rod 40, the nut seat 7 can reciprocate along the length direction of the third guide rod 41. During the movement of the nut seat 7, the drive shaft 42 moves synchronously. During the movement of the drive shaft 42, the drive shaft 42 is engaged with the first gear 43 and the first rack 44, thereby rotating the drive shaft 42. Therefore, while the drive shaft 42 reciprocates along the length direction of the third guide rod 41, the drive shaft 42 can also rotate. During the rotation of the drive shaft 42, the first cam 57 rotates synchronously. During the rotation of the first cam 57, when the raised portion of the first cam 57 abuts against the adjustment plate 8, the adjustment plate 8 moves toward the position where the inner wall of the water guide tube 5 is located, and the first spring is compressed; when the raised portion of the first cam 57 no longer abuts against the adjustment plate 8, the adjustment plate 8 is reset under the action of the first spring, and the adjustment plate 8 moves away from the inner wall of the water guide tube 5.

[0071] When the adjusting plate 8 makes reciprocating motion toward the position of the spray hole 9, the adjusting plate 8 can push the water to spray out, thereby enhancing the force of the water spraying, making the water act at a longer distance and a wider range, thereby accelerating the dust reduction speed and shortening the dust reduction time.

[0072] Furthermore, when the adjustment plate 8 makes reciprocating motion toward the position where the spray holes 9 are located, the adjustment plate 8 can also move toward or away from the position where the hollow plate 6 is located, so that each time the adjustment plate 8 moves toward the position where the spray holes 9 are located, the number of spray holes 9 that the adjustment plate 8 can act on is different. When the number of spray holes 9 spraying water decreases, the pressure in the water guide tube 5 will increase, so that the distance at which the water can act is farther. When the number of spray holes 9 spraying water increases, the pressure in the water guide tube 5 will decrease, so that the distance at which the water can act is restored to the initial state. Through the above-mentioned movement, by adjusting the number of spray holes 9, the distance at which the water can act can be changed from near to far or from far to near, thereby ensuring that the water can comprehensively reduce the dust dispersed in the air, further improving the utilization rate of water, and enhancing the effect of water.

[0073] The hollow rubber block 10 is provided so that when the regulating plate 8 pushes the water out, a negative pressure environment will be formed between the regulating plate 8 and the inner wall of the water guide tube 5, so that the water can be sprayed farther and have a wider range of action under the action of negative pressure, and can contact the dust dispersed in the air more fully, thereby further improving the efficiency of the water action.

[0074] During the reciprocating motion of the adjusting plate 8 toward the position close to the inner wall of the water guide tube 5, the auxiliary block 46 can also reciprocate under the joint action of the adjusting plate 8 and the second spring. During the motion of the auxiliary block 46, the third rack moves synchronously. During the motion of the third rack, the third rack meshes with the third gear 47, so that the third gear 47 rotates. During the rotation of the third gear 47, the first screw 17 rotates synchronously. During the rotation of the first screw 17, the second gear 45 rotates synchronously. During the rotation of the second gear 45, the second gear 45 drives the second rack to reciprocate toward the position close to the spray hole 9. During the motion of the second rack, the side block 13 moves synchronously. During the motion of the side block 13, the conical block 15 moves synchronously.

[0075] While the conical block 15 is continuously moving toward the position where the spray hole 9 is located, the conical block 15 can extend into the spray hole 9, thereby reducing the diameter of the water sprayed from the spray hole 9 and increasing the pressure in the spray hole 9, so that the water sprayed from the spray hole 9 has a stronger force under the action of the conical block 15. After the force of the water spray is enhanced, the water can act at a farther distance and in a wider range, which ensures that the water can contact more dust in the air and speed up the dust reduction process. In addition, after the force of the water is enhanced, the water can also disperse the dust dispersed in the air, reducing the probability of dust agglomeration.

[0076] Furthermore, during the vertical reciprocating motion of the adjusting rod 14, the adjusting rod 14 can disperse the water sprayed from the spray hole 9 into a plurality of water droplets. After the water is dispersed into water droplets, the range in which the water can act is further expanded, so that the water can contact the dust more fully and comprehensively.

[0077] After the water is dispersed under the vertical action of the plurality of adjusting rods 14, the diffusion block 20 reciprocates along the length direction of the first guide rod 18 with the movable block 19. During the reciprocating motion of the plurality of diffusion blocks 20, the plurality of diffusion blocks 20 can further perform a step of horizontal dispersion processing on the water droplets after the action of the adjusting rods 14, that is, the water droplets can be dispersed into a plurality of water droplets with smaller particle sizes. Through the above movement, the contact area between the water droplets and the dust can be increased, ensuring that the water droplets contact the dust more fully and thoroughly, and further improving the utilization rate of the water droplets.

[0078] To sum up, under the vertical action of the adjusting rod 14 and the lateral action of the diffusion block 20, the water can be broken up into a number of water droplets with smaller particle sizes, and then the dust can be reduced by the water droplets, which can further enhance the dust reduction effect, improve the dust reduction efficiency, and ensure the dust reduction quality.

[0079] During the rotation of the first screw rod 17, the second screw rod 33 rotates synchronously with the first screw rod 17 under the action of the belt 51. During the rotation of the second screw rod 33, the side block 35 can drive the swing block 36 to reciprocate along the length direction of the second guide rod 34.

[0080] During the reciprocating motion of the swing block 36, the swing block 36 can drive the swing frame 32 to swing back and forth. During the swinging of the swing frame 32, the movement path of the water droplets can be changed, so that the water droplets will be sprayed from different directions, that is, the diffusion range of the water droplets when sprayed will be further expanded, and the water droplets can be diffused over a large area, so that the dust reduction area of ​​the water droplets is more sufficient and more complete, thereby further improving the utilization rate of the water droplets, enhancing the dust reduction effect, and ensuring the dust reduction quality.

[0081] During the rotation of the third screw rod 40, the fifth gear 55 and the sixth gear 56 are meshed, thereby driving the connecting shaft 48 to rotate. During the rotation of the connecting shaft 48, the second cam 49 rotates synchronously. During the rotation of the second cam 49, when the raised portion of the second cam 49 abuts against the piston block 23, the piston block 23 moves away from the position where the outer wall of the water guide cylinder 5 is located, and the third spring 50 is compressed; when the raised portion of the second cam 49 no longer abuts against the piston block 23, the piston block 23 is reset under the action of the third spring 50, and the piston block 23 moves to the position close to the outer wall of the water guide cylinder 5. Therefore, the piston block 23 can reciprocate along the length direction of the piston cylinder 22.

[0082] During the movement of the piston block 23, the piston block 23 and the piston cylinder 22 cooperate with each other to enable the compressed air to be continuously ejected from the guide hole 27. During the ejection of the compressed air, the compressed air has a certain force, and the compressed air can act on the water droplets. That is, with the assistance of the compressed air, the water droplets can enhance the force of the water droplets when ejected, expand the range of the water droplets, and further enhance the dust reduction effect of the water droplets on the dust, which promotes a more comprehensive and complete contact between the water droplets and the dust, and accelerates the progress of dust reduction.

[0083] During the movement of the third rack, the third rack drives the squeezing plate 31 to move synchronously through the fixed block 30. During the movement of the squeezing plate 31, the squeezing plate 31 can continuously squeeze the conduit 26, that is, the conduit 26 will continuously deform. During the deformation of the conduit 26, the pressure in the conduit 26 will increase, thereby further increasing the force of the compressed air ejected from the guide hole 27. After the force of the compressed air increases, the movement speed of the water droplets can be further accelerated, the range of action of the water droplets is increased, the utilization rate of the water droplets is improved, and the water droplets can be more efficiently dusted.
