Description

Technical Field

[0001] This utility model belongs to the field of chemical safety production technology, and in particular, it is a dust suppression device for chemical safety production. Background Technology

[0002] Chemical production processes refer to the production processes that chemically process raw materials to ultimately obtain valuable products. Looking at the numerous and complex chemical production processes, they are all organically combined with chemical (biological) reactions and several physical operations. A large amount of dust is generated during chemical production processes, and dust suppression devices are generally used to suppress the dust. However, most dust suppression devices now have fixed nozzle positions, which cannot be adjusted specifically, resulting in a small dust suppression range and thus reducing the dust suppression effect.

[0003] There is an existing Chinese patent (authorization announcement number CN213912890U) for a dust suppression device for chemical safety production, which: "includes a production workshop, the production workshop is equipped with mechanical equipment, a connecting plate is fixedly connected to the left end of the production workshop, a suction fan is fixedly connected to the top of the production workshop, a first suction pipe is connected to the lower end of the suction fan, and a connecting pipe is connected to the lower end of the first suction pipe."

[0004] It is evident that the cited patent document suffers from the problem of making it difficult to make targeted adjustments to the nozzle. Utility Model Content

[0005] The purpose of this invention is to provide a dust suppression device for safe chemical production, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression device for chemical safety production, comprising a dust suppression base, a horizontal block mounted on the top surface of the dust suppression base via a bracket, rotating rods rotatably connected to the inner walls of both sides of the horizontal block, connecting plates connected to the free ends of the two rotating rods, connecting rods connected to opposite sides of the two connecting plates, two vertical plates passing through the horizontal block sleeved on the periphery of the two connecting rods, movable blocks rotatably connected to opposite sides of the two vertical plates via pins, hinge plates hinged to one side of each of the two movable blocks, two bases symmetrically mounted on the top surface of the horizontal block, adjusting plates rotatably connected to the inner cavities of the two bases via rotating shafts, the free ends of the two hinge plates respectively hinged to one side of the two adjusting plates, and atomizing nozzles for dust suppression in the chemical production process mounted on one side of each of the two adjusting plates.

[0007] Preferably, two limiting rods are symmetrically welded to the top surface of the horizontal block, and the two movable blocks are respectively slidably sleeved on the periphery of the two limiting rods.

[0008] Preferably, one end of one of the rotating rods passes through a cross block and is connected to a rotating handle, and a mounting box is installed on one side of the cross block.

[0009] Preferably, a spring is connected to the inner wall of the mounting box, and a movable plate is connected to the free end of the spring.

[0010] Preferably, one side of the movable plate extends through the mounting box and is connected to a locking block, and the surface of the throttle is provided with a plurality of slots that are adapted to the locking block at equal intervals.

[0011] Preferably, the top surface of the dust-reducing base is equipped with a water tank with two water pumps, and the two water pumps on one side of the water tank are connected to telescopic hoses.

[0012] Preferably, the free ends of the two telescopic hoses pass through two adjusting plates and are connected to two atomizing nozzles.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This dust suppression device for chemical safety production provides power for the rotation of the rotating rod and connecting rod by turning the handle. In conjunction with the vertical plate, it realizes the longitudinal reciprocating motion of the movable block, thereby driving the adjusting plate to rotate clockwise and counterclockwise around the rotating shaft, adjusting the angle of the atomizing nozzle. Compared with the existing dust suppression devices, this device can adjust the angle of the atomizing nozzle, thus expanding the dust suppression range and treating dust in different locations.

[0015] The welded limiting rod can limit the longitudinal reciprocating motion trajectory of the moving block, preventing deviation.

[0016] By moving the movable plate, power can be provided to move the card block, thereby moving it out of or into the slot. This can fix the throttle, thereby fixing the rotating rod and preventing the rotating rod and connecting rod from rotating due to external factors. Attached Figure Description

Detailed Implementation

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] like Figures 1 to 4 The dust suppression device for chemical safety production shown includes a dust suppression base 1, with multiple casters installed on the top surface of the dust suppression base 1 and a push handle installed on the top surface of the dust suppression base 1 to facilitate personnel to move the dust suppression base 1 to the work area.

[0028] A horizontal block 2 is mounted on the top surface of the dust-collecting base 1 via a bracket. Rotating rods 3 are rotatably connected to the inner walls of both sides of the horizontal block 2. Connecting plates 4 are connected to the free ends of the two rotating rods 3. Connecting rods 5 are connected to the opposite sides of the two connecting plates 4. Two vertical plates 6 are fitted around the periphery of the two connecting rods 5, penetrating the horizontal block 2. Movable blocks 7 are rotatably connected to the opposite sides of the two vertical plates 6 via pins. By rotating the rotating rods 3, the connecting plates 4 can be rotated, thereby causing the connecting rods 5 to rotate. Since the vertical plates 6 are fitted around the periphery of the connecting rods 5, when the connecting rods 5 rotate, one end of the vertical plates 6 will be driven to make a circular motion. Since the movable blocks 7 are rotatably connected to one side of the vertical plates 6 via pins, when one end of the vertical plates 6 makes a circular motion, it will drive the movable blocks 7 to make a longitudinal reciprocating motion.

[0029] Each of the two vertical plates 6 has a through hole on one side for the connecting rod 5 to pass through. Bearings are installed on the inner walls of the two through holes, and the outer walls of the two bearings are connected and fixed to the inner walls of the two through holes. The connecting rod 5 passes through the two bearings and is connected and fixed to the inner walls of the two bearings. When the vertical plate 6 rotates, it will drive the outer ring of the bearing to rotate, so that the bearing can restrict the position of the vertical plate 6 without affecting the rotation of the vertical plate 6.

[0030] Each of the two movable blocks 7 has a hinge plate 8 hinged to one side. Two bases 9 are symmetrically mounted on the top surface of the horizontal block 2. The inner cavities of both bases 9 are rotatably connected to adjusting plates 10 via rotating shafts. The two adjusting plates 10 can rotate forward and backward around the rotating shaft. The free ends of the two hinge plates 8 are respectively hinged to one side of the two adjusting plates 10. Each side of the two adjusting plates 10 is equipped with an atomizing nozzle 11 for dust suppression in chemical production processes. When the movable blocks 7 reciprocate longitudinally, they drive the hinge plates 8 forward. When the movable block 7 moves upward, it pushes the adjusting plate 10 through the hinge plate 8, allowing the adjusting plate 10 to rotate clockwise around the pivot. Conversely, when the movable block 7 moves downward, it pulls the adjusting plate 10 through the hinge plate 8, allowing the adjusting plate 10 to rotate counterclockwise around the pivot. This adjusts the angle of the atomizing nozzle 11, thereby expanding the dust suppression range and enabling the treatment of dust in different locations, thus improving the dust suppression effect in the chemical safety production process.

[0031] Two limiting rods 20 are symmetrically welded to the top surface of the horizontal block 2. Two movable blocks 7 are slidably sleeved on the periphery of the two limiting rods 20. When the movable blocks 7 perform longitudinal reciprocating motion, they will move on the periphery of the limiting rods 20, which can limit the movement trajectory of the movable blocks 7 and ensure that the movable blocks 7 can only perform longitudinal reciprocating motion.

[0032] One end of one of the rotating rods 3 passes through the horizontal block 2 and is connected to the handle 12, making it convenient for people to rotate the rotating rod 3.

[0033] A mounting box 13 is installed on one side of the horizontal block 2. A spring 14 is connected to the inner wall of the mounting box 13. A movable plate 15 is connected to the free end of the spring 14. One side of the movable plate 15 passes through the mounting box 13 and is connected to a locking block 16. A pull rod passing through the mounting box 13 is connected to the other side of the movable plate 15. Several slots 17 that fit the locking blocks 16 are evenly spaced on the surface of the throttle 12. In the initial state, the locking blocks 16 are inside the slots 17. When the throttle 12 needs to be turned, the person pulls the pull rod, which moves the movable plate 15 and compresses the spring 14. The spring 14 will deform after being compressed. The change buffers the force received. When the moving plate 15 moves, it will drive the locking block 16 to move, so that the locking block 16 can be removed from the locking slot 17. At this time, the operator can turn the handle 12 to adjust the angle of the adjusting plate 10. When the adjusting plate 10 is adjusted to a suitable angle and the locking block 16 is aligned with one of the locking slots 17, the operator releases the lever. The spring 14 will then push the moving plate 15 and the locking block 16 back to their original positions, allowing the locking block 16 to engage in the aligned locking slot 17. This fixes the position of the handle 12 and prevents the rotating rod 3 from rotating due to external factors.

[0034] The top surface of the dust suppression base 1 is equipped with a water tank 18 with two water pumps. The two water pumps on one side of the water tank 18 are connected to telescopic hoses 19. The free ends of the two telescopic hoses 19 pass through two adjusting plates 10 and are connected to two atomizing nozzles 11. By turning on the water pumps, the water in the water tank 18 can be transported to the atomizing nozzles 11 through the telescopic hoses 19 and sprayed out, so that the water mist mixes with the dust and can perform dust suppression.

[0035] Working principle:

[0036] This dust suppression device for chemical safety production allows the dust suppression base 1 to be moved to the work area by pushing the handle and using the casters. Then, turning on the water pump delivers water from the water tank 18 to the atomizing nozzle 11 via the telescopic hose 19, allowing the water mist to mix with the dust for dust suppression. To adjust the angle of the atomizing nozzle 11, turning the handle 12 rotates the rotating rod 3, which in turn rotates the connecting rod 5 via the connecting plate 4. Since the vertical plate 6 is fitted around the connecting rod 5, the rotation of the connecting rod 5 causes one end of the vertical plate 6 to rotate. One side of the vertical plate 6 is rotatably connected to a movable... When one end of the vertical plate 6 moves in a circular motion, it drives the movable block 7 to move longitudinally back and forth, which in turn drives the hinge plate 8 to move. When the movable block 7 moves upward, it pushes the adjusting plate 10 through the hinge plate 8, so that the adjusting plate 10 can rotate clockwise around the axis of rotation. Conversely, when the movable block 7 moves downward, it pulls the adjusting plate 10 through the hinge plate 8, so that the adjusting plate 10 can rotate counterclockwise around the axis of rotation, thereby adjusting the angle of the atomizing nozzle 11, thereby expanding the dust suppression range, enabling the treatment of dust in different locations, and improving the dust suppression effect in the chemical safety production process.
