Description

Two fifth rotating shafts 59 move upwards through the side end of the horizontal plate 19, and driven gears 58 are fixed to the surface of each of the two fifth rotating shafts 59. Both driven gears 58 mesh with the drive gear ring 60. The drive motor 16 drives the first gear 17 to rotate, and the first gear 17 drives the second gear 17 to rotate. 8 rotates, the second gear 18 drives the rotating tube 4 to rotate, the rotating tube 4 drives the fixed rod 7 to rotate, the fixed rod 7 drives the two horizontal plates 19 to rotate, the two horizontal plates 19 drive the two cleaning brushes 22 to perform circular motion, wipe and clean the inner wall of the cylinder, and at the same time drive the driven gear 58 to perform circular motion, the driving gear ring 60 drives the driven gear 58 to rotate, the driven gear 58 drives the fifth rotating shaft 59 to rotate, the fifth rotating shaft 59 drives the first rotating rod 24 to rotate, the first rotating rod 24 drives the extrusion rod 23 to perform circular motion, the extrusion rod 23 slides in the first sliding groove 26 when it performs circular motion, the extrusion rod 23 thereby drives the vertical rod 25 to perform relative reciprocating swing around the first rotating shaft 20 as the center, the fixed cylinder 21 drives the cleaning brushes 22 to swing and clean during the circular motion;

[0054] Two positioning plates 68 are fixed to both sides between two horizontal plates 19. Each end of the two positioning plates 68 has a third rotating shaft 41. The surfaces of the four third rotating shafts 41 are each fixed with a second rotating rod 42. The sides of the four second rotating rods 42 are each fixed with a connecting plate. The sides of the four connecting plates are each fixed with multiple air nozzles for blowing air to clean the inner wall of the cylinder. Each positioning plate 68 has a swing cleaning assembly. Two sets of swing cleaning assemblies are used to drive the multiple air nozzles to swing and blow air. Each set of swing cleaning assemblies includes a first groove 45 formed within the positioning plate 68. A fourth rotating shaft 57 rotates within the first groove 45. A third rotating rod 50 is fixed to the side end of 57. Two limiting rods 46 are fixed in the first groove 45. The same sliding plate 47 slides on the surface of the two limiting rods 46. A third sliding groove 48 is opened in the sliding plate 47. A second slider 49 slides in the third sliding groove 48. The second slider 49 is fixed to the side end of the third rotating rod 50.

[0055] Furthermore, the second connecting pipe 54 is fixedly connected to the air inlet pipe 2 for supplying air into multiple jet nozzles.

[0056] Example 2

[0057] Improvement based on Embodiment 1: In this embodiment, a device for powerfully cleaning cylinder is provided, including a cleaning pipe 1, an air inlet pipe 2 and a rotating assembly. The rotating assembly includes a rotating joint 3 and a rotating pipe 4. The air inlet pipe 2 is connected to the rotating joint 3, and the rotating pipe 4 is connected to the cleaning pipe 1. The rotating pipe 4 and the rotating joint 3 are rotatably connected and their inner cavities remain connected.

[0058] Multiple air jet holes 11 are provided axially along the cleaning pipe 1. One end of the air inlet pipe 2 is connected to an external air source and the other end is connected to the rotary joint 3 so that the air inlet pipe 2 is connected to the cleaning pipe 1.

[0059] It is understandable that clean air enters the cleaning pipe 1 through the air inlet pipe 2, and then exits from the jet hole 11 on the cleaning pipe 1 to blow the material on the inner wall of the cylinder to the bottom of the cylinder.

[0060] At least one set of cleaning pipes 1, which are symmetrically arranged and located near the inner wall of the cylinder, are connected to the rotating pipe 4;

[0061] The cleaning pipe 1 includes a connecting pipe 12 and a jet pipe 13. The left and right ends of the connecting pipe 12 are connected to the jet pipe 13 and the rotating pipe 4, respectively. The jet hole 11 is provided on the jet pipe 13.

[0062] The opening direction of the jet nozzle 11 forms an angle with the horizontal direction, and the angle ranges from 20° to 40°. It can be understood that the opening direction of the jet nozzles 11 on both sides of the rotating pipe 4 and the cleaning pipe 1 forms an angle with the axis of the connecting pipe 12, and the opening directions of the jet nozzles 11 on both sides are opposite. When the cleaning pipe 1 rotates within the cylinder, the direction of the gas ejected from the jet nozzles 11 on both sides is at the same angle.

[0063] The rotary joint 3 includes a protective sleeve 31, a first connecting pipe 32, and a connecting joint 33. One end of the first connecting pipe 32 is connected to the connecting joint 33, and the other end is connected to the bearing of the rotary pipe 4. The protective sleeve 31 is fitted onto the connection between the first connecting pipe 32 and the connecting joint 33. It can be understood that the upper end of the rotary joint 3 is connected to the intake pipe 2, and the rotary joint 3 is connected to the rotary pipe 4 through the first connecting pipe 32. When the rotary pipe 4 rotates, driving the cleaning pipe 1 to rotate in the cylinder, the rotary joint 3 remains stationary, so that the intake pipe 2 remains stationary during the operation of this invention.

[0064] Bearing 34 is disposed between rotating tube 4 and first connecting tube 32.

[0065] The bearing 34 is sleeved outside the first connecting tube 32. The first connecting tube 32 has grooves at the upper and lower ends of the bearing 34 for the first limiting block 35 and the second limiting block 36 to engage. The rotating tube 4 has a protrusion for placing the bearing 34. The protrusion is located at the lower end of the second limiting block. The rotating tube 4 has a threaded pressure plate 37. The pressure plate 37 is located at the upper end of the first limiting block 35.

[0066] Example 3

[0067] Improvements based on Example 1: See Appendix Figure 11 -Appendix Figure 14 It includes at least one symmetrically arranged scraper assembly 5, a fixing assembly 6, and a fixing rod 7 disposed at the lower end of the rotating tube 4. The fixing rod 7 extends downward to a position near the bottom of the cylinder body, and the two scraper assemblies 5 are fixedly connected to the fixing rod 7 through the fixing assembly 6.

[0068] It is understandable that in Embodiment 1, clean gas is sprayed out through the jet hole 11 to blow the material on the inner wall of the cylinder to the bottom of the cylinder. However, the material that has been stuck to the inner wall of the cylinder for a long time has formed a deposit that is difficult to blow off. It is easier to scrape the deposits on the inner wall of the cylinder by using the scraper assembly 5. The scraper assembly 5 is fixed to the fixing rod 7 by the fixing assembly 6. When the rotating tube 4 rotates, the scraper assembly 5 also rotates to scrape the deposits on the inner wall of the cylinder.

[0069] The present invention employs symmetrical scraper assemblies 5 on both sides of the fixed rod 7, which facilitates installation and disassembly, and also facilitates modular production.

[0070] The scraper assembly 5 and the cleaning pipe 1 are at a certain angle. It can be understood that the scraper assembly 5 and the cleaning pipe 1 are not on the same horizontal line, and both the scraper assembly 5 and the cleaning pipe 1 are driven by the rotating pipe 4 to complete the rotation process.

[0071] The scraper assembly 5 includes a cleaning component 51, a mounting plate 52, and a connecting rod 53. The cleaning component 51 is detachably mounted on the mounting plate 52, and the two ends of the connecting rod 53 are fixedly connected to the mounting plate 52 and the fixing rod 7, respectively. It is understood that prolonged use of the cleaning component 51 to scrape material from the inner wall of the cylinder will wear down the contact area between the cleaning component 51 and the inner wall of the cylinder. The detachable and replaceable cleaning component 51 allows for the reuse of the remaining parts of the scraper assembly 5, except for the cleaning component 51.

[0072] The cleaning component 51 is a deformable structure, and the length of the scraper assembly 5 is adapted to the inner diameter of the cylinder. It can be understood that, due to the cylinder's shape being smaller at the top and larger at the bottom, the deformable structure of the cleaning component 51 allows the invention to be smoothly installed into the cylinder and fit snugly against the inner wall of the cylinder. The cleaning component 51 can be a reasonable structural component such as brush bristles or an integrated scraper.

[0073] The fixing component 6 includes a fastening body and a first fastener 61. The fastening body is sleeved on the outer wall of the fixing rod 7, and the fastening body has a through hole 63 for the fixing rod 7 to pass through. The outer side of the fastening body has a plurality of first fastening holes 611 adapted to the first fastener 61. The first fastening holes 611 transversely penetrate the fastening body and communicate with the through hole 63. It can be understood that, firstly, the fixing rod 7 passes through the through hole 63 on the fastening body to a certain position. When the present invention is in this position, the length of the scraper assembly 5 is adapted to the length of the inner wall of the cylinder. At the same time, the first fastener 61 is inserted into the first fastening hole 611 to fix the fixing component 6 to the fixing rod 7.

[0074] The fastening body has bushings 65 at both its upper and lower ends that are fitted over the fixing rod 7. The first fastening hole 611 is located on the bushing 65. The fastening body is fixedly connected to the fixing rod 7 via a first fastener 61. It can be understood that the first fastening hole 611 is located on the bushings 65 at both ends. The diameter of the bushing 65 is smaller than the diameter of the fastening body but larger than the diameter of the fixing rod 7. The first fastener 61 passes through the first fastening hole 611 to limit the movement of the fastening body at both ends, thus fixing the fixing component 6 to the fixing rod 7.

[0075] The fastening body has a limiting groove 62 for placing and matching the connecting rod 53. It can be understood that placing the connecting rod 53 in the limiting groove 62 fixes the connecting rod 53 to the fixing component 6, thereby indirectly achieving a fixed connection between the connecting rod 53 and the fixing rod 7.

[0076] The fastening body is provided with a second fastener 64. The fastening body consists of a set of symmetrically arranged first fastening parts 66 and second fastening parts 67. The first fastening parts 66 and the second fastening parts 67 are respectively provided with a plurality of second fastening holes 641 adapted to the second fastener 64 at relative positions. It can be understood that the fastening body can be integrally formed or separately arranged. In this invention, the fastening parts are arranged symmetrically. The first fastening parts 66 and the second fastening parts 67 are provided with limiting grooves 62 for placing the connecting rod 53. At the same time, the second fastener 67 adapts to the second fastening holes 641 and passes through the first fastening parts 66 and the second fastening parts 67 in sequence, so that the fastening body fixes the connecting rod 63 in the limiting groove.

[0077] The connecting rod 53 has a semi-circular locking block 531 on the side near the fixed rod 7. The semi-circular locking blocks 531 on the two symmetrically arranged connecting rods 53 are connected to form a locking block that fits onto the fixed rod 7. The first fastening part 66 and the second fastening part 67 are provided with semi-circular slots 532 that are adapted to the semi-circular locking blocks 531. It can be understood that the connection between the semi-circular locking blocks 531 and the slots 532 on the connecting rods 53 makes the connecting rods 53 fixed on the fixing component 6, which is more effective.
