Description

Technical Field

[0001] This utility model relates to the technical field of electrostatic dust removal devices, and in particular to an adjustable electrostatic dust removal device suitable for chemical workshops. Background Technology

[0002] The large amount of dust generated in chemical workshops not only shortens the service life of equipment, but also threatens the health of workers. Electrostatic dust removal is a method of gas dust removal. When dust-laden gas passes through a high-voltage electrostatic field, it is electrically separated. After the dust particles combine with negative ions and become negatively charged, they tend to discharge and deposit on the anode surface. It is used in metallurgical and chemical industries to purify gases or recover useful dust particles.

[0003] However, the dust collection mechanism of electrostatic precipitators is usually fixed, and can only collect dust within its fixed coverage area. It cannot flexibly adjust the position and angle according to the actual distribution of dust. For some areas with high dust concentration or where the position changes, it cannot collect dust in a timely and effective manner. Therefore, we need to consider how to solve this problem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable electrostatic dust removal device suitable for chemical workshops. This device incorporates a rotating shaft, gears, and racks, allowing the oscillating plate to swing along with the dust collection plate. This enables the dust collection head to collect dust from different angles within the chemical workshop, expanding the dust collection range and improving dust collection efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable electrostatic precipitator suitable for chemical workshops includes a dust collection box. Multiple rollers are installed at the lower end of the dust collection box. A chute is formed in the inner top of the dust collection box. A sliding plate is slidably connected to the inner wall of the chute. One side wall of the sliding plate is elastically connected to the inner wall of the chute by multiple springs. An electrostatic precipitator is installed at the lower end of the sliding plate. A dust discharge hopper is fixedly connected to the lower end of the dust collection box. Two fixed plates are fixedly connected to one side wall of the dust collection box. A drive shaft is rotatably connected between the two fixed plates. Two... The dust collector has two swing plates, one of which is fixedly connected to the other end of a suction plate. The suction plate is hollow inside and has multiple suction heads connected to its bottom. A second threaded rod is rotatably connected between the top and bottom of the dust collector. A movable plate is threaded onto the second threaded rod. A movable cover is fixedly connected to one side wall of the movable plate. A fan is installed at the top of the dust collector. The fan's air inlet is connected to the inside of the suction plate through an air inlet pipe. The fan's air outlet is connected to the inside of the movable cover through an air outlet pipe. An air outlet pipe is fixedly connected to the other side wall of the dust collector.

[0007] Preferably, a rotating shaft is rotatably connected to one inner wall of the dust collector, and a cam is fixedly connected to the outer wall of the rotating shaft. The cam cooperates with the electrostatic precipitator. A first motor is installed on the outer wall of the dust collector, and the end of the output shaft of the first motor extends into the dust collector and is fixedly connected to one end of the rotating shaft.

[0008] Preferably, a gear is fixedly connected to the outer wall of the drive shaft, and arc-shaped plates are fixedly connected to the opposite sides of the two fixed plates. Arc-shaped grooves are opened in the two arc-shaped plates. Two fixed blocks are fixedly connected to the upper end of the dust collector box. One end of each of the two arc-shaped plates is fixedly connected to the corresponding fixed block. Guide rods are fixedly connected to the opposite sides of the two swing plates. Both guide rods are slidably connected to the inner wall of the corresponding arc-shaped groove.

[0009] Preferably, two mounting plates are fixedly connected to one side wall of the dust collector, and a first threaded rod is rotatably connected between the two mounting plates. A movable block is threadedly connected to the first threaded rod, and a rack is fixedly connected to one end of the movable block. The rack meshes with a gear.

[0010] Preferably, a second motor is installed at the lower end of the dust collection box, and the output shaft of the second motor extends into the interior of the dust collection box and is fixedly connected to the lower end of the second threaded rod.

[0011] Preferably, the lower end of the first threaded rod passes through the corresponding mounting plate and is connected to the output shaft of the second motor via a transmission mechanism. The transmission mechanism includes two pulleys, which are respectively mounted on the lower end of the first threaded rod and the output shaft of the second motor, and are connected by belt drive.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The structure is designed with gears, arc plates, and racks. When the rack moves under the drive of the first threaded rod, it drives the gears to rotate, which in turn causes the drive shaft to swing the swing plate and the dust collection plate. This expands the dust collection range, allowing the dust collection head to collect dust in the chemical workshop from different angles, thus improving the comprehensiveness and efficiency of dust collection.

[0014] 2. The structure includes a first threaded rod, a movable plate, and a movable cover. Rotating the first threaded rod allows the movable plate, along with the movable cover, to move up and down inside the dust collection box, thereby changing the airflow distribution entering the electrostatic precipitator. This allows dust to pass through the electrostatic precipitator more evenly, improving dust adsorption efficiency and resulting in better dust removal. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-7An adjustable electrostatic precipitator suitable for chemical workshops includes a dust collection box 1. Multiple rollers 2 are installed at the lower end of the dust collection box 1, allowing the device to move flexibly within the chemical workshop. A sliding groove 3 is formed in the inner top of the dust collection box 1. A sliding plate 4 is slidably connected to the inner wall of the sliding groove 3. One side wall of the sliding plate 4 is elastically connected to the inner wall of the sliding groove 3 by multiple springs 5. An electrostatic precipitator 6 is installed at the lower end of the sliding plate 4. The electrostatic precipitator 6 is existing technology and will not be described in detail here. A rotating shaft 7 is rotatably connected to one side inner wall of the dust collection box 1. A cam 8 is fixedly connected to the outer wall of the rotating shaft 7. In conjunction with the electrostatic precipitator 6, a first motor 9 is installed on the outer wall of the dust collection box 1. The output shaft of the first motor 9 extends into the interior of the dust collection box 1 and is fixedly connected to one end of the rotating shaft 7. The electrostatic precipitator 6 can efficiently capture dust particles in the dust collection box 1 by utilizing the principle of electrostatic adsorption. At the same time, the first motor 9 drives the rotating shaft 7 and the cam 8 to rotate, causing the electrostatic precipitator 6 to vibrate under the elastic action of the spring 5. This vibration helps to shake off the dust adsorbed on the electrostatic precipitator 6, avoiding dust accumulation that affects the dust removal effect and ensuring that the electrostatic precipitator 6 works continuously and efficiently.

[0025] The dust collector 1 has a dust outlet hopper 10 fixedly connected to its lower end. A sealing plate is installed at the lower end of the dust outlet hopper 10. The sealing plate temporarily stores the collected dust in the dust outlet hopper 10. Once a certain amount of dust has accumulated, the sealing plate is opened for unified cleaning. Two fixed plates 11 are fixedly connected to one side wall of the dust collector 1. A drive shaft 12 is rotatably connected between the two fixed plates 11. Two swing plates 13 are fixedly connected to the outer wall of the drive shaft 12. A suction plate 14 is fixedly connected to the other end of both swing plates 13. 4 is hollow inside, and multiple suction heads 15 are connected to the bottom inside. Gears 16 are fixedly connected to the outer wall of the drive shaft 12. Arc plates 17 are fixedly connected to the opposite sides of the two fixed plates 11. Arc grooves are opened in the two arc plates 17. The arc plates 17 and the arc grooves provide guidance for the swing of the swing plate 13 and the suction plate 14, ensuring that they swing according to a specific arc trajectory. Two fixed blocks 18 are fixedly connected to the upper end of the dust collection box 1. One end of each of the two arc plates 17 is fixedly connected to the corresponding fixed block 18.

[0026] In this structure, guide rods 19 are fixedly connected to the opposite sides of the two swing plates 13. Both guide rods 19 are slidably connected to the inner wall of the corresponding arc-shaped groove. The cooperation between the guide rods 19 and the arc-shaped groove restricts the movement direction and range of the swing plates 13, preventing them from shaking, shifting, or excessively swinging, thereby enhancing the stability of the entire dust collection structure. Two mounting plates 20 are fixedly connected to one side wall of the dust collection box 1. A first threaded rod 21 is rotatably connected between the two mounting plates 20. A moving block 22 is threaded onto the first threaded rod 21. A rack 23 is fixedly connected to one end of the moving block 22. The rack 23 meshes with a gear 16, and the movement is controlled by the first threaded rod 21. Rotation of the rack 23 causes the gear 16 to rotate, which in turn causes the dust collection plate 14 and the dust collection head 15 to swing. This expands the dust collection range and collects dust in the chemical workshop from different angles, improving dust collection efficiency. A second threaded rod 24 is rotatably connected between the top and bottom of the dust collection box 1. A movable plate 25 is threaded onto the second threaded rod 24. A movable cover 26 is fixedly connected to one side wall of the movable plate 25. By rotating the second threaded rod 24, the movable plate 25 moves up and down with the movable cover 26 inside the dust collection box 1, thereby allowing the dust to pass through the electrostatic precipitator 6 more evenly and improving the dust adsorption efficiency.

[0027] The dust collector 1 has a second motor 27 installed at its lower end. The second motor 27 is a servo motor. The output shaft of the second motor 27 extends into the dust collector 1 and is fixedly connected to the lower end of the second threaded rod 24. The lower end of the first threaded rod 21 passes through the corresponding mounting plate 20 and is connected to the output shaft of the second motor 27 via a transmission mechanism 28. The transmission mechanism 28 includes two pulleys, which are respectively installed on the lower end of the first threaded rod 21 and the output shaft of the second motor 27. The two pulleys are connected by a belt. The dust collection box 1 is connected by a transmission. A fan 29 is installed on the upper end of the dust collection box 1. The air inlet of the fan 29 is connected to the inside of the dust collection plate 14 through the air inlet pipe. The air outlet of the fan 29 is connected to the inside of the movable cover 26 through the air outlet pipe. Both the air inlet pipe and the air outlet pipe are flexible hoses. An air outlet pipe 30 is fixedly connected to the other side wall of the dust collection box 1. The fan 29 draws the air containing dust into the dust collection plate 14 through the dust collection head 15, and then sends it into the movable cover 26 through the air inlet pipe, the fan 29 and the air outlet pipe. Finally, after being treated by the electrostatic precipitator 6, the clean air is discharged from the air outlet pipe 30.

[0028] In this utility model, during use, the entire device is first moved to the location where dust removal is required by multiple rollers 2. Then, the fan 29 is started. After the fan 29 is started, under its suction, the air containing dust in the chemical workshop is sucked into the dust collection plate 14 through multiple dust collection heads 15. After passing through the dust collection plate 14, the air enters the fan 29 through the air inlet pipe and is then sent into the movable hood 26 through the air outlet pipe. After entering the movable hood 26, the dust-containing air passes through the electrostatic precipitator 6. The electrostatic precipitator 6 uses the principle of electrostatic adsorption to make the dust particles charged and adsorbed on the electrostatic precipitator 6, thereby separating the dust from the air and realizing the dust removal function.

[0029] During the above process, the first motor 9 can be started to make the rotating shaft 7 rotate, which in turn makes the cam 8 rotate. When the cam 8 rotates, it will continuously squeeze the electrostatic precipitator 6. Thus, under the squeezing of the cam 8 and the elastic action of the spring 5, the electrostatic precipitator 6 will vibrate and shake off the dust adsorbed on the electrostatic precipitator 6, so that the dust falls into the dust discharge hopper 10 below, avoiding the accumulation of dust and affecting the dust removal effect of the electrostatic precipitator 6.

[0030] In addition, the second motor 27 can be started to rotate the second threaded rod 24, which in turn causes the moving plate 25 to move up and down with the moving cover 26 inside the dust collection box 1. The up and down movement of the moving cover 26 can change the airflow distribution entering the electrostatic precipitator 6, so that the dust can pass through the electrostatic precipitator 6 more evenly and improve the dust adsorption efficiency. The second motor 27 also drives the first threaded rod 21 to rotate through the transmission mechanism 28, which in turn causes the moving block 22 to move with the rack 23. The movement of the rack 23 will cause the gear 16 meshing with it to rotate, which in turn causes the transmission shaft 12 to rotate. In this way, the swing plate 13 and the dust collection plate 14, which are fixedly connected to the transmission shaft 12, will also swing together. When the dust collection plate 14 swings, the dust collection head 15 below it will also swing, thereby expanding the dust collection range and enabling the collection of dust in the chemical workshop from different angles.

[0031] Finally, the clean air processed by the electrostatic precipitator 6 is discharged from the air outlet pipe 30 connected to the other side wall of the dust collector 1. The dust that falls into the dust hopper 10 can be temporarily stored through the sealing plate set at the lower end of the dust hopper 10. After the dust accumulates to a certain amount, the sealing plate is opened for unified cleaning.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
