Description

[0002] The background technology for dust removal devices in slag powder production stems from the demand for resource utilization of solid waste in the building materials and metallurgical industries.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Reference Figures 1-3 and Figure 5 As shown, a dust removal device for slag powder production includes an electrostatic precipitator body 1, a corona wire 2, and a dust collection plate 3. A drive lifting assembly 4 is provided at the left end of the electrostatic precipitator body 1 and the dust collection plate 3. The drive lifting assembly 4 is fixedly connected to one end of several suction pipes 5, which are arranged in parallel. The other end of the suction pipes 5 is fixedly connected to a lifting rod assembly 6. The other end of the suction pipes 5 is also fixedly connected to one end of a flexible hose. The other end of the flexible hose is fixedly connected to the upper end of a conical tube 7. The lower end of the conical tube 7 is fixedly connected to the upper end of a separation chamber assembly 8. An air pump 9 is fixedly connected inside the separation chamber assembly 8. A sliding air pump 9 is installed inside the separation chamber assembly 8. A filter assembly 10 is connected, and a curved guide plate assembly 20 is provided at the lower end of the filter assembly 10. The front and rear sides of the filter assembly 10 are respectively fixedly connected to one end of two connecting shafts 30. A slider assembly 40 is fixedly connected to the two connecting shafts 30. The two slider assemblies 40 are respectively slidably connected to two sliding grooves 50. The two sliding grooves 50 are respectively fixedly connected to the front and rear ends of the separation chamber assembly 8. A drive reciprocating vibration assembly 60 is also fixedly connected to the rear end of the separation chamber assembly 8. One end of the drive reciprocating vibration assembly 60 abuts against the connecting shaft 30. Two suction pipes 5 are provided between every two adjacent dust collection plates 3 in the electrostatic precipitator body 1.

[0022] When it is necessary to separate slag powder from dust, firstly, the corona wire 2 and the dust collection plate 3 are energized. The mixture of slag powder and dust is driven by the airflow into the left side of the electrostatic precipitator body 1. The dust is discharged through the corona wire 2, causing it to become negatively charged and move towards the dust collection plate 3. The uncharged slag powder flows out from the right side of the electrostatic precipitator body 1 with the airflow. In this way, the slag powder and dust are separated. However, a small amount of slag powder will be negatively charged and will be adsorbed onto the dust collection plate 3 along with the dust. Therefore, the separation operation is stopped after the electrostatic precipitator has been working for a period of time. At this time, the lifting assembly 4 drives several suction pipes 5 to move up and down together. At this time, the air pump 9 keeps the separation chamber assembly 8 in a low air pressure state. Since the separation chamber assembly 8 is connected to the suction pipe 5, the suction pipe 5 is also in a low air pressure state. The outside of the suction pipe 5 is relatively high pressure. The mixture of slag powder and dust adsorbed on the dust collection plate 3 is forced into the suction pipe 5 by the high air pressure. Then it enters the hose from the right end of the suction pipe 5 and then enters the conical tube 7. Since the diameter of the upper end of the conical tube 7 is larger than the diameter of the lower end, the mixture enters from the upper end of the conical tube 7 and flows out from the lower end of the conical tube 7. The speed increases. Then the mixture falls onto the filter screen assembly 10. The mixture with smaller particle size can fall through the filter screen and then pass through the curved guide plate assembly 20 and fall into the water at the bottom of the separation chamber assembly 8. Because slag powder is denser than dust, it sinks to the bottom of the water first. Once it reaches the bottom, the slag powder at the bottom is discharged with the water, thus separating it from the dust. Since the particle sizes of the slag powder and dust are not uniform, the reciprocating vibration component 60 drives the connecting shaft 30 to move up and down. Simultaneously, the connecting shaft 30 drives the slider component 40 and the filter screen component 10 to move up and down together. The mixture of slag powder and dust that falls onto the filter screen component 10 and cannot continue falling moves up and down with it, creating a vibration effect. This causes the mixture of slag powder and dust to collide. Combining these two methods pulverizes the mixture of slag powder and dust, preventing the uneven particle sizes from causing some of them to fall at the same speed, which would increase the difficulty of separation.

[0023] Reference Figures 2-3 and Figure 6As shown, the drive lifting assembly 4 includes two motors 41. The two motors 41 are fixedly connected to the front and rear ends of the left side of the inner cavity of the electrostatic precipitator body 1. The output ends of the two motors 41 are fixedly connected to bevel gears 42. The two bevel gears 42 mesh with two bevel gears 43 respectively. The two bevel gears 43 are fixedly connected to the lower ends of two lead screws 44 respectively. The two lead screws 44 are rotatably connected inside the electrostatic precipitator body 1. The two lead screws 44 are engaged with the two ends of the lifting rod 45 through threaded holes. The lifting rod 45 is fixedly connected to one end of several suction pipes 5.

[0024] The reciprocating rotation of motor 41 drives the reciprocating rotation of bevel gear 42, which is fixedly connected to it. Through the meshing of bevel gear 42 and bevel gear 43, bevel gear 42 drives bevel gear 43 to reciprocate as it reciprocates, which in turn drives lead screw 44 to reciprocate. The reciprocating rotation of lead screw 44 causes lifting rod 45 to move up and down, which in turn causes suction pipe 5 to move up and down. A mixture of slag powder and dust is introduced into the electrostatic precipitator body 1. After a period of time, because the dust collection plate 3 is adsorbed with slag powder and dust, the suction pipe 5 moves up and down, and its movement path covers the entire surface of the dust collection plate 3, which is beneficial for absorbing the mixture of slag powder and dust on the surface of the dust collection plate 3.

[0025] Reference Figure 4 and Figure 7 As shown, the lifting rod assembly 6 includes a second lifting rod 61. The two ends of the second lifting rod 61 are slidably connected to two guide rods 62 respectively. The two guide rods 62 are fixedly connected in the inner cavity of the electrostatic precipitator body 1. The two guide rods 62 are located on the right side of the inner cavity of the electrostatic precipitator body 1. The two guide rods 62 are arranged parallel to the two lead screws 44. The second lifting rod 61 is arranged parallel to the first lifting rod 45. The second lifting rod 61 is fixedly connected to the other end of several suction pipes 5. The other end of several suction pipes 5 is also fixedly connected to one end of several hoses. The other end of several hoses is fixedly connected to the upper end of several tapered tubes 7.

[0026] When the vacuum cleaner pipe 5 moves up and down, it drives the lifting rod 61, which is fixedly connected to it, to move up and down together. This causes the lifting rod 61 to slide up and down on the guide rod 62, so that both ends of the vacuum cleaner pipe 5 slide up and down synchronously, making the vacuum cleaner pipe 5 slide more stably.

[0027] Several suction pipes 5 have several suction ports 51, and the suction ports 51 are close to the surface of the dust collection plate 3.

[0028] Since the suction port 51 is close to the surface of the dust collection plate 3, when the suction pipe 5 moves up and down, the suction port 51 can cover one side of the dust collection plate 3. Through the air pump 9, the air pressure inside the suction pipe 5 is lower than the external air pressure. As a result, the mixture of slag powder and dust attached to the dust collection plate 3 enters the suction pipe 5 through the suction port 51 under the action of external air pressure. Then the mixture moves towards the low-pressure area, that is, towards the hose and the conical tube 7. The mixture passes through the hose and the conical tube 7 in sequence, enters the conical tube 7 from the upper end of the conical tube 7, and then flows out from the lower end of the conical tube 7. Since the diameter of the lower end of the conical tube 7 is small, the flow rate of the mixture increases when it passes through the lower end of the conical tube 7.

[0029] Reference Figure 5 and Figure 9 As shown, the separation chamber assembly 8 includes a cover 81, the lower ends of several conical tubes 7 are fixedly connected to the cover 81, the cover 81 is fixedly connected to the upper end of the chamber body 82, the chamber body 82 is fixedly connected to the outer side of the right end of the electrostatic precipitator body 1, a valve 83 is fixedly connected to the lower end of the chamber body 82, and an air pump 9 is fixedly connected inside the chamber body 82.

[0030] The mixture of slag powder and dust sucked into the suction pipe 5 moves towards the low-pressure area due to the air pressure difference. As a result, the mixture flows out from the right end of the suction pipe 5 into the hose and then into the upper end of the conical pipe 7, flows out from the lower end of the conical pipe 7, and enters the chamber 82. Because the mixture flows out from the lower end of the conical pipe 7, the flow rate of the mixture increases, and the mixture quickly enters the chamber 82 and moves towards the bottom of the chamber 82.

[0031] Reference Figure 5 , Figure 8 and Figure 10 As shown, the filter assembly 10 includes an arc-shaped filter 101, which is located above the inner cavity of the chamber 82. Connecting plates 102 are fixedly connected to both the front and rear sides of the arc-shaped filter 101. The two connecting plates 102 are fixedly connected to one end of the two connecting shafts 30 respectively. The lower ends of several tapered tubes 7 are located directly above the arc-shaped filter 101.

[0032] As the mixture flows into the chamber 82 at a faster rate, it impacts the arc-shaped filter screen 101, causing larger slag powder and dust particles to be broken up. The mixture entering the chamber 82 falls onto the arc-shaped filter screen 101. Smaller particles pass through the arc-shaped filter screen 101 and continue to fall, while larger particles remain on the arc-shaped filter screen 101 and then slide down to the lowest end of the arc-shaped filter screen 101.

[0033] The lower end of the arc-shaped filter screen 101 is fixedly connected to the upper end of the box-shaped filter screen 103.

[0034] The box-shaped filter 103 has a space inside that can hold the mixture. The mixture that slides to the lowest end of the arc-shaped filter 101 then falls from the connection between the arc-shaped filter 101 and the box-shaped filter 103 into the box-shaped filter 103. The mixture with smaller particle size continues to fall from the box-shaped filter 103.

[0035] The curved guide plate assembly 20 includes several curved guide plate bodies 201, which are fixedly connected inside the cabin 82. The curved guide plate bodies 201 are arranged in parallel below the box-shaped filter screen 103. An air pump 9 is arranged above the box-shaped filter screen 103 and is fixedly connected inside the cabin 82.

[0036] Smaller particles of the mixture continuing to fall from the box-shaped filter screen 103 pass between several curved guide plate bodies 201, which slows down their falling speed and thus prevents the slag powder and dust from falling too fast and impacting the water surface.

[0037] Both slider assemblies 40 include slider bodies 401. The two slider bodies 401 are fixedly connected to the two connecting shafts 30 respectively. The two slider bodies 401 are slidably connected to the two slide grooves 50. The two slide grooves 50 are fixedly connected to the front and rear sides of the cabin 82. The upper ends of the two slider bodies 401 are fixedly connected to one end of the two springs 402 respectively. The other ends of the two springs 402 are fixedly connected to the outer side of the cabin 82. The two springs 402 are arranged longitudinally.

[0038] When the connecting shaft 30 moves up and down, it drives the slider body 401 to slide up and down on the slide groove 50. The spring 402 is compressed or stretched, which at the same time drives the arc-shaped filter screen 101 and the box-shaped filter screen 103 to move up and down together. The up and down movement of the box-shaped filter screen 103 generates a vibration effect, which causes the mixture of larger-diameter slag powder and dust falling into the internal space of the box-shaped filter screen 103 to collide fully, thereby reducing its particle size.

[0039] The reciprocating vibration drive assembly 60 includes a second motor 601, which is fixedly connected to the outer side of the rear end of the cabin 82. The output end of the second motor 601 is fixedly connected to a cam 602, and the other end of a connecting shaft 30 abuts against the cam 602.

[0040] The rotation of motor 601 drives the rotation of cam 602. Since the other end of connecting shaft 30 abuts against cam 602, the rotation of cam 602 causes connecting shaft 30 to move up and down.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
