Description

Technical Field

[0001] This utility model relates to the field of air classifier cleaning technology, specifically a rotor air classifier cleaning device. Background Technology

[0002] A powder classifier is an industrial piece of equipment. In the production of some powder materials, the particle size of the powder produced varies. Depending on the application of the powder, a powder classifier is needed to separate the powders according to their particle size. During long-term operation, powder particles and dust inevitably accumulate on the internal structure of the powder classifier. In order to ensure the quality of powder sorting, the internal structure of the powder classifier needs to be cleaned regularly.

[0003] When cleaning an air classifier, due to its complex internal structure, it needs to be disassembled for cleaning. Some types of air classifiers contain a rotor with several ring-shaped blades, which are mainly used to separate and classify the materials entering the air classifier, playing a core role. In the existing technology, the blades on the rotor are arranged relatively closely, making it extremely easy for dust to accumulate during cleaning. It is necessary for staff to wipe each blade individually, and since there are a large number of blades on the rotor, this seriously affects the cleaning efficiency of the air classifier.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This rotor classifier cleaning device uses a cleaning tank filled with cleaning water and a locking mechanism to fix the sand layer in the cleaning tank. Abrasive sand is then added to the sand layer. During cleaning, the rotor body is removed from the classifier and mounted on the guide mechanism, causing the blades at the lower end of the rotor body to sink into the sand layer and remain below the water surface. The tumbling mechanism in the sand layer continuously agitates the abrasive sand in the water, causing the rotor blades submerged in the water to be continuously impacted by the abrasive sand carried by the water flow, achieving a grinding and washing effect. This ensures thorough cleaning without dead angles, eliminating the need for manual wiping and cleaning of each blade individually. The rotor body can be cleaned quickly, significantly improving the cleaning efficiency of the classifier.

[0017] 2. This rotor classifier cleaning device, by setting up a base, a winding mechanism, a lifting mechanism, and a guide mechanism, addresses the issue of the rotor body being large and difficult to lift. The winding mechanism controls the lifting mechanism to fold and flatten the rotor, allowing the structure on the guide mechanism to be placed vertically. Subsequently, the rotor body can be hoisted and placed directly on the guide mechanism, enabling the rotor body to be directly and accurately submerged into the cleaning tank, thus improving the convenience of cleaning the classifier rotor body.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-9 A cleaning device for a rotor classifier includes: a cleaning tank 1, which is funnel-shaped and has an integral drain outlet 2 at its bottom; a sand-turning layer 9 is provided inside the cleaning tank 1; the inner wall of the cleaning tank 1 is engaged with the sand-turning layer 9 by a locking mechanism 10; a turning mechanism 11 is rotatably provided inside the sand-turning layer 9; a first driving mechanism 3 is provided at the bottom of the inner wall of the cleaning tank 1; and the bottom end of the turning mechanism 11 passes through the sand-turning layer 9 and is inserted into the first driving mechanism 3.

[0030] A base 4 is provided on the back of the cleaning tank 1. A lifting mechanism 6 is rotatably provided on the base 4. A guide mechanism 7 is provided on the top of the lifting mechanism 6. A rotor body 8 is sleeved on the front end of the guide mechanism 7. The lower end of the rotor body 8 is submerged in the water filled in the cleaning tank 1. The sand layer 9 contains abrasive made of silica. A winding mechanism 5 is provided on the base 4.

[0031] The locking mechanism 10 includes a clamp 101, which is integrally installed on the inner wall of the cleaning tank 1. A pressure pin 102 is provided on the clamp 101, and a spring 104 is sleeved on the pressure pin 102. A sleeve 103 that slides with the pressure pin 102 is sleeved on the outside of the spring 104. A clamping block 105 is integrally provided on the outer edge of the sleeve 103. The bottom of the clamping block 105 overlaps with the sanding layer 9. By setting the locking mechanism 10, the sanding layer 9 can be quickly disassembled from the cleaning tank 1. After cleaning a number of rotor bodies 8, it is convenient to remove the sanding layer 9 to replace the abrasive, thus ensuring the cleaning effect of the subsequent rotor bodies 8.

[0032] The sand-forming layer 9 includes a washing hood 91, which is divided into an upper section and a lower section. The upper and lower sections of the washing hood 91 are respectively provided with a drain hole 92 and a water intake hole 93. The turning mechanism 11 is located in the lower section where the water intake hole 93 is located. The particle size of the abrasive is larger than the aperture of the drain hole 92 and the water intake hole 93. As the turning mechanism 11 operates, the water flow in the sand-forming layer 9 is pushed upward and falls back along the edge. At this time, the sewage and dust particles after washing will reach the edge of the sand-forming layer 9 with the water flow and be pushed outward through the drain hole 92, so that some sewage and dust particles fall into the outside of the sand-forming layer 9 through the drain hole 92, thereby maximizing the cleanliness of the water flow in the sand-forming layer 9.

[0033] Among them, the washing cover 91 is provided with a locking sleeve 94 along the front and rear edges, and an ultrasonic vibrator 95 is inserted into the inside of the locking sleeve 94. The washing cover 91 is provided with a locking groove 96 along the left and right edges, and the position of the locking groove 96 corresponds to the position of the locking mechanism 10. By setting the locking sleeve 94 and inserting the ultrasonic vibrator 95, the water flow in the cleaning tank 1 will generate ultrasonic waves, which will achieve the effect of ultrasonic cleaning and further improve the cleaning effect of the rotor body 8.

[0034] The first drive mechanism 3 includes a bracket 31 installed inside the cleaning tank 1. A shaft 32 is rotatably installed in the middle of the bracket 31. The bottom end of the shaft 32 passes through the cleaning tank 1 through a mechanical seal and a first motor 33 is installed at the bottom of the shaft 32. A hexagonal seat 34 is installed at the top end of the shaft 32. The hexagonal seat 34 is inserted into the turning mechanism 11. By setting the first motor 33 as the power source of the first drive mechanism 3, the turning mechanism 11 can be directly driven to rotate by the first motor 33 after it is inserted into the first drive mechanism 3.

[0035] The tumbling mechanism 11 includes a limiting seat 111, with a hexagonal groove 112 at the bottom and a vortex shaft 113 at the top. The vortex shaft 113 is equipped with vortex blades 114. When the tumbling mechanism 11 is inserted into the first drive mechanism 3 along with the placement of the sand layer 9, starting the first drive mechanism 3 can drive the tumbling mechanism 11 to tumble the abrasive in the sand layer 9, so that the abrasive can fully contact the blades of the rotor body 8 and avoid leaving dead corners.

[0036] The winding mechanism 5 includes a roller 51 rotatably mounted on the base 4. One end of the roller 51's shaft passes through the base 4 and is equipped with a second motor 52. A pull rope 54 is wound on the roller 51. A first guide roller 53 is rotatably mounted on the roller 51. The end of the roller 51 passes through the outer edge of the first guide roller 53 and through the second guide wheel 12 mounted on the washing tank 1, and is then folded back onto the lifting mechanism 6. By setting up the winding mechanism 5, the rotation of the lifting mechanism 6 can be directly controlled by the winding state of the winding mechanism 5, thereby facilitating the control of the lifting mechanism 6 to lay flat and stand upright.

[0037] The lifting mechanism 6 includes a main lifting column 61 rotatably mounted on the base 4. The top of the main lifting column 61 has a sliding groove and a sliding column 62 is slidably mounted inside it. The top of the sliding column 62 is provided with a mounting seat 63. A guide rotation mechanism 7 is mounted on the mounting seat 63. A hydraulic cylinder 64 is embedded in the main lifting column 61. The piston rod of the hydraulic cylinder 64 passes through the main lifting column 61 and is installed at the bottom of the sliding column 62. A rubber pad 13 is provided on the main lifting column 61. The rubber pad 13 overlaps with the back of the cleaning tank 1. By setting up the lifting mechanism 6, when the rotor body 8 is driven to stand up, the lifting mechanism 6 can be controlled to raise the height of the rotor body 8 first, so that the rotor body 8 is completely suspended above the cleaning tank 1, and then the height is lowered, so that the lower end of the rotor body 8 can be submerged in the water for cleaning.

[0038] The guide rotation mechanism 7 includes a cover 71 mounted on the top structure of the lifting mechanism 6. A long shaft 74 is rotatably mounted inside the cover 71. One end of the long shaft 74 passes through the lifting mechanism 6 and is equipped with a third motor 73. A disc base 72 is provided at the end of the cover 71 away from the lifting mechanism 6. A driven pulley 76 is sleeved on the main shaft of the disc base 72. A main pulley 75 is sleeved inside the cover 71 on the long shaft 74. The main pulley 75 and the driven pulley 76 are connected by a drive belt 77. A slot is opened at the bottom of the cover 71 for the drive belt 77 to pass through. By setting the third motor 73 as the power source and setting the disc base 72 as the support mechanism for cleaning the rotor body 8, the rotor body 8 can be rotated by turning on the third motor 73 during the cleaning process, thereby gradually cleaning the outer edge of the rotor body 8 without the need for manual turning, which improves the convenience of cleaning.

[0039] The working principle is as follows: When the air classifier needs to be cleaned, the abrasive is first placed in the sand-turning layer 9. After a certain amount of water is injected into the cleaning tank 1, the sand-turning layer 9 is fixed in the cleaning tank 1 by the locking mechanism 10. Then, the air classifier is completely disassembled. The winding mechanism 5 is controlled to lower the lifting mechanism 6 to a flat position. The rotor body 8 is then hoisted and placed on the guide rotation mechanism 7. The winding mechanism 5 is started to control the lifting mechanism 6 to gradually stand up. At the same time, the lifting mechanism 6 is started to raise the height of the rotor body 8 on the guide rotation mechanism 7. When the rotor body 8 is suspended directly above the cleaning tank 1, the lifting mechanism 6 is controlled to lower the height of the rotor body 8 so that the lower end of the rotor body 8 sinks below the water surface in the sand-turning layer 9. Then, the first drive mechanism 3 is started to make the turning mechanism 11 start to stir. At the same time, the guide rotation mechanism 7 is started to make the rotor body 8 rotate slowly. The abrasive in the sand-turning layer 9 is used to continuously wash the rotor body 8 with the water flow until the cleaning is completed.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
