Description

Technical Field

[0001] The invention belongs to the technical field of cyclone separators, and in particular relates to an anti-blocking device for a cyclone separator. Background Art

[0002] A cyclone separator is a device that separates gas-solid systems or liquid-solid systems. It usually introduces airflow, causing it to rotate inside the device, which creates a greater centrifugal force in the gas, thereby throwing dust particles inside the gas out of the gas, thereby purifying the gas. Cyclone separators are widely used because of their simple structure, great operational flexibility, high efficiency and easy maintenance.

[0003] However, in the gas processing process of the existing cyclone separator, when the gas medium contains large solid particles or impurities, these particles or impurities may be deposited inside the cyclone separator and cause blockage, especially on the cyclone cylinder and other parts of the cyclone separator. Due to the centrifugal force generated by the rotation of the airflow, the particles or impurities are more likely to be thrown to the wall and deposited;

[0004] In addition, a screen is installed at the clean air outlet of some cyclone separators to further filter and intercept solid particles. When the dust-laden gas passes through the screen, fine solid particles will be intercepted by the screen, thereby further improving the separation effect. However, too many impurities attached to the screen will cause the screen holes to be blocked, affecting the exhaust effect and then affecting the gas treatment work.

[0005] Therefore, we propose an anti-blocking device for a cyclone separator to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that during the gas processing process of the existing cyclone separator, when the gas medium contains larger solid particles or impurities, these particles or impurities may be deposited inside the cyclone separator and cause blockage, especially on the cyclone cylinder and other components of the cyclone separator. Due to the centrifugal force generated by the rotation of the airflow, particles or impurities are more easily thrown to the wall of the device and deposited. A screen will be set at the clean air outlet of some cyclone separators to further filter and intercept solid particles. When the dust-containing gas passes through the screen, fine solid particles will be intercepted by the screen, thereby further improving the separation effect. However, too many impurities attached to the screen will cause the filter holes of the screen to be blocked, affecting the exhaust effect and then affecting the gas processing work. A blockage prevention device for a cyclone separator is proposed.

[0035] An annular rotating plate 8 is rotatably installed inside the upper end of the columnar shell 1 through the ball bearing 9. The setting of the ball bearing 9 enables the annular rotating plate 8 to rotate stably while reducing the friction between the annular rotating plate 8 and the columnar shell 1, thereby increasing the service life of the annular rotating plate 8. The lower surface of the annular gear plate 7 is fixedly connected to the upper surface of the annular rotating plate 8, so that when the servo motor 4 drives the rotating gear 6 to rotate, the rotating gear 6 can drive the annular rotating plate 8 to rotate through the annular gear plate 7. Vertical plates 10 are provided on both sides of the lower end of the annular rotating plate 8. A horizontal plate 11 is provided on one side of the two vertical plates 10 close to the clean air discharge pipe 3. A vertical plate 2 12 is provided on the lower end of the other side of the two horizontal plates 11. A cleaning brush 13 is provided on one side of the vertical plate 10 and the vertical plate 2 12. The two groups of cleaning brushes 13 are respectively in contact with the inner side wall of the columnar shell 1 and the outer side wall of the clean air discharge pipe 3.

[0036] It should be noted that the two groups of cleaning brushes 13 are in close contact with the inner wall of the columnar outer shell 1, the inner wall of the conical outer shell 2 and the outer wall of the clean air exhaust pipe 3, respectively, so that when the cleaning brushes 13 rotate, they can clean and scrape the inner wall of the columnar outer shell 1, the inner wall of the conical outer shell 2 and the outer wall of the clean air exhaust pipe 3, respectively, and then sweep away the dust and impurities that fall on the inner wall of the columnar outer shell 1, the inner wall of the conical outer shell 2 and the outer wall of the clean air exhaust pipe 3, so that the dust and impurities are smoothly discharged from the ash outlet by gravity.

[0037] A rotating rod 14 is rotatably installed in the middle of the inner part of the horizontal plate 11, a rotating block 15 is arranged on the circumferential surface of the rotating rod 14, a striking hammer 16 is arranged at the lower end of the rotating block 15, a driven gear 17 is arranged on the circumferential surfaces of the front and rear sides of the rotating block 15, a spur plate 18 is meshedly connected at the upper end of the driven gear 17, and the spur plate 18 is slidably installed inside the horizontal plate 11, a push plate 19 is arranged in the middle of the upper surface of the spur plate 18, and the push plate 19 is of trapezoidal design, a push block 20 is arranged on the inner top wall of the columnar housing 1, and two push blocks 20 are arranged, and the two push blocks 20 correspond to the left and right sides of the push plate 19 respectively;

[0038] The upper surface of the horizontal plate 11 near the side of the vertical plate 2 12 is rotatably connected with the inside of the columnar housing 1 through the support rotating plate 40. The upper end of the horizontal plate 11 is provided with a horizontal through groove 21, a slide groove 22 and a moving groove 23. The horizontal through groove 21 is connected to the slide groove 22, and the horizontal through groove 21 is connected to the moving groove 23. There are two slide grooves 22. The push plate 19 is located in the middle of the horizontal through groove 21. The straight tooth plate 18 is arranged inside the moving groove 23. The setting of the moving groove 23 provides a space for the straight tooth plate 18 to move, so that the straight tooth plate 1 8 can smoothly move horizontally, the left and right ends of the push plate 19 are respectively arranged inside the two slide grooves 22, and the two push blocks 20 are matched with the two slide grooves 22 respectively. The setting of the slide grooves 22 provides a movable space for the push plate 19, so that the push plate 19 can smoothly move horizontally. The setting of the horizontal through groove 21 enables the push block 20 to smoothly enter the inside of the horizontal through groove 21 when the horizontal plate 11 rotates, thereby pushing the push plate 19 horizontally, and then the push plate 19 drives the driven gear 17 to rotate;

[0039] It should be noted that one of the two push blocks 20 is arranged at the top rear side of the columnar housing 1, and the other is arranged at the top front side of the columnar housing 1. At the same time, the trapezoidal design of the push plate 19 enables the horizontal plate 11 to rotate to the rear side at the top of the columnar housing 1, and the horizontal plate 11 will approach the rear push block 20, so that the rear push block 20 enters the horizontal through groove 21 close to the side of the vertical plate 10. Then, when the horizontal plate 11 continues to rotate, due to the trapezoidal design of the push plate 19, the push block 20 will push the push plate 19 to the right, so that the push plate 19 drives the spur plate 18 to the right, and then drives the driven gear 17, the rotating block 15 and the rotating rod 14 to rotate, and then drives the striking hammer 1 6 deflects to the left, so that the striking hammer 16 strikes the vertical plate 10 once, causing the cleaning brush 13 on the vertical plate 10 to vibrate and shake off the dust attached to the cleaning brush 13, and then the horizontal plate 11 continues to rotate, so that the pushing block 20 moves out of the horizontal slot 21 as a whole, and the striking hammer 16 is reset by gravity. Similarly, when the horizontal plate 11 rotates to the front side, the pushing block 20 at the front end will enter the horizontal slot 21 close to the side of the vertical plate 12, and then when the horizontal plate 11 continues to rotate, the pushing block 20 will push the pushing plate 19 to the left, causing the striking hammer 16 to deflect to the right and strike the vertical plate 12 once, so that the dust attached to the surface of the cleaning brush 13 on the vertical plate 12 is shaken off.

[0040] A screen 25 is provided inside the clean air discharge pipe 3, and a lifting connection block 26 is provided on the upper surface of the screen 25. The lifting connection block 26 is L-shaped and is arranged in a circumferential array. A connecting rod 27 is provided on the upper and lower surfaces of the plurality of lifting connection blocks 26. A return spring 28 is sleeved on the circumferential surface of the connecting rod 27. The lower end of the return spring 28 is connected to the inner wall of the clean air discharge pipe 3, and the upper end of the return spring 28 is connected to the lifting connection block 26. The lower end of the connecting rod 27 is provided with a semi-return spring 28. The two vertical plates 12 are provided with a push plate 24 at the lower end, and the front and rear sides of the push plate 24 are both arc-shaped. One end of the push plate 24 is arranged at the lower end of the clean air discharge pipe 3 and abuts against one of the semicircular protrusions 29. The arc-shaped design of the front and rear sides of the push plate 24 enables the push plate 24 to smoothly push the semicircular protrusion 29 upward when it rotates horizontally, so that the semicircular protrusion 29 can move vertically back and forth under the action of the push plate 24 and the return spring 1 28;

[0041] It should be noted that the arrangement of several groups of lifting connecting blocks 26, connecting rods 27, return springs 28 and semicircular protrusions 29 enables the push plate 24 to squeeze the semicircular protrusions 29 more frequently, so that the screen 25 can vibrate faster, and then the dust and impurities attached to the lower surface of the screen 25 can be shaken off more smoothly.

[0042] The inner bottom of the clean air discharge pipe 3 is provided with a mounting groove 42, and the upper end of the lifting connection block 26, the connecting rod 27, the return spring 28 and the semicircular protrusion 29 are all arranged inside the mounting groove 42. The setting of the mounting groove 42 provides installation space for the upper end of the lifting connection block 26, the connecting rod 27, the return spring 28 and the semicircular protrusion 29, and at the same time enables the lifting connection block 26, the connecting rod 27 and the semicircular protrusion 29 to move vertically smoothly. The inner side wall of the clean air discharge pipe 3 is provided with a movable groove 30, and the movable groove 30 is symmetrically arranged in two groups up and down. Sealing plates 31 are slidably installed inside the two groups of movable grooves 30. The two sealing plates 31 are respectively connected to the upper and lower sides of the upper part of the lifting connection block 26. The setting of the movable groove 30 provides a movable space for the lifting connection block 26 and the sealing plate 31. The setting of the sealing plate 31 can close the movable groove 30 without affecting the vertical movement of the lifting connection block 26, so as to prevent dust and impurities from flowing out through the movable groove 30.

[0043] The lower ends of the two vertical plates 10 are each provided with a horizontal plate 2 32, and the two horizontal plates 2 32 are rotatably mounted on the outer portion of the lower end of the conical shell 2 through an annular rotating plate 2 33. The setting of the annular rotating plate 2 33 can limit and support the horizontal plate 2 32, thereby improving the stability of the horizontal plate 2 32 and the lower portion of the vertical plate 10 without affecting the rotation of the vertical plate 10 and the horizontal plate 2 32. The outer sides of the upper surfaces of the two horizontal plates 2 32 are each provided with a push block 2 34, and the outer side wall of the lower portion of the conical shell 2 is rotatably mounted with a knocking hammer 2 35 through a fulcrum 36, and a plurality of knocking hammers 2 35 are arranged in a circular array. The setting of several groups of knocking hammers 2 35 enables the knocking hammers 2 35 to knock and vibrate the conical shell 2 more frequently, so that the shell can vibrate and shake off the dust and impurities deposited on the inner wall of the shell. A circular pressure block 37 is provided at the lower end, and the circular pressure block 37 is located on the annular moving path of the push block 2 34, so that a connecting plate 38 is provided on the inner side of the circular pressure block 37, and a return spring 2 39 is provided on the inner side of the connecting plate 38, and the other end of the return spring 2 39 is connected to the outer side wall of the conical shell 2. When the cross plate 2 32 drives the push block 2 34 to rotate horizontally, the push block 2 34 can push the circular pressure block 37 in the direction of the conical shell 2, so that the circular pressure block 37 drives the knocking hammer 2 35 to rotate, so that the upper end of the knocking hammer 2 35 is away from the conical shell 2, and then after the push block 2 34 is no longer in contact with the circular pressure block 37, the knocking hammer 2 35 is reset under the elastic force of the return spring 2 39, and before resetting, because the swing is more violent, it will first knock on the conical shell 2, causing the conical shell 2 to vibrate.

[0044] When the present invention is in use, when the cyclone separator is working, the servo motor 4 is started, and the servo motor 4 drives the rotating shaft 5 and the rotating gear 6 to rotate, so that the rotating gear 6 drives the annular rotating plate 1 8 to rotate through the annular gear plate 7, and then drives the vertical plate 1 10, the horizontal plate 1 11 and the vertical plate 2 12 to rotate, so that the cleaning brushes 13 on the vertical plate 10 and the vertical plate 2 12 clean and scrape the inner wall of the columnar shell 1, the inner wall of the conical shell 2 and the outer wall of the clean air discharge pipe 3, and sweep away the dust and impurities attached and deposited thereon, so that the dust and impurities are discharged from the ash outlet under the action of gravity;

[0045] During the rotation of the horizontal plate 11, the horizontal plate 11 will first approach the rear push block 20, so that the rear push block 20 enters the horizontal through groove 21 close to the side of the vertical plate 10. Then, when the horizontal plate 11 continues to rotate, due to the trapezoidal design of the push plate 19, the push block 20 will push the push plate 19 to the right, so that the push plate 19 drives the spur plate 18 to the right, and then drives the driven gear 17, the rotating block 15 and the rotating rod 14 to rotate, and then drives the knocking hammer 16 to deflect to the left, so that the knocking hammer 16 knocks the vertical plate 10 once, so that the cleaning on the vertical plate 10 is The sweeping brush 13 vibrates to shake off the dust attached to the sweeping brush 13, and then the horizontal plate 11 continues to rotate, so that the push block 20 moves out of the horizontal slot 21 as a whole, and the knocking hammer 16 is reset by gravity. Similarly, when the horizontal plate 11 rotates to the front side, the push block 20 at the front end will enter the horizontal slot 21 close to the side of the vertical plate 2 12, and then when the horizontal plate 11 continues to rotate, the push block 20 will push the push plate 19 to the left, so that the knocking hammer 16 deflects to the right and knocks the vertical plate 2 12 once, so that the dust attached to the surface of the sweeping brush 13 on the vertical plate 2 12 is shaken off;

[0046] The vertical plate 2 12 will also drive the push plate 24 to rotate during the rotation process. When the push plate 24 contacts the semicircular protrusion 29 during the rotation process, the semicircular protrusion 29 will be pushed upward into the interior of the clean air discharge pipe 3, so that the semicircular protrusion 29 pushes the connecting rod 27, the lifting connecting block 26 and the screen 25 to move upward. Then, after the push plate 24 is no longer in contact with the semicircular protrusion 29, the semicircular protrusion 29, the connecting rod 27, the lifting connecting block 26 and the screen 25 are reset downward under the action of the reset spring 1 28, so as to realize the vertical reciprocating movement of the screen 25, thereby shaking off the dust and impurities attached to the lower surface of the screen 25, and preventing the impurities from clogging the filter holes and affecting the exhaust effect.

[0047] During the rotation of the vertical plate 10, the horizontal plate 2 32, the annular rotating plate 2 33 and the push block 2 34 are also driven to rotate. When the push block 2 34 rotates to contact the circular pressure block 37, the push block 2 34 can push the circular pressure block 37 in the direction of the conical shell 2, so that the circular pressure block 37 drives the knocking hammer 2 35 to rotate, so that the upper end of the knocking hammer 2 35 is away from the conical shell 2, and then after the push block 2 34 is no longer in contact with the circular pressure block 37, the knocking hammer 2 35 is reset under the elastic force of the reset spring 2 39, and before resetting, because the swing is more violent, it will first knock on the conical shell 2, causing the conical shell 2 to vibrate, thereby further shaking off the dust and impurities deposited on the inner wall of the shell, thereby improving the dust removal effect.
