Abstract
Description
Technical Field
[0001] This utility model relates to the field of hollow ball screening technology, specifically a hollow ball screening machine with a spiral propulsion structure. Background Technology
[0002] Hollow alumina spheres are a new type of high-temperature insulation material. They are made by melting and blowing industrial alumina in an electric furnace, and the crystal form is α-Al2O3 microcrystals. Using hollow alumina spheres as the main body, various shapes of products can be made. The maximum service temperature is 1800℃. The products have high mechanical strength, several times that of general lightweight products, while the bulk density is only half that of corundum products.
[0003] After the production of alumina hollow spheres, they generally need to be screened to separate small particles and broken hollow spheres to improve the overall quality of the product. Currently, when screening hollow spheres, most methods involve feeding them directly onto a conical drum installed above the screening machine. However, this method can easily lead to material accumulation at the opening of the feeding drum, preventing discharge. Increasing the diameter of the feeding drum can result in excessively fast feeding, which can negatively impact subsequent screening of the hollow spheres.
[0004] Therefore, we propose a hollow ball screening machine with a spiral propulsion structure. Utility Model Content
[0005] The purpose of this invention is to provide a hollow ball screening machine with a spiral propulsion structure to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a hollow ball screening machine with a spiral propulsion structure, comprising a processing barrel, a feeding barrel placed above the processing barrel, a feeding pipe fixedly connected to the bottom surface of the feeding barrel, the feeding pipe being fixedly connected to the processing barrel, a feeding assembly installed inside the feeding pipe, the feeding assembly being used for spiral feeding of materials inside the feeding barrel, the feeding assembly allowing for more uniform feeding of materials into the feeding barrel and preventing feeding jamming, and a screening assembly installed inside the processing barrel, the screening assembly being used for screening the materials fed into the feeding barrel.
[0007] Preferably, the feeding assembly includes a drive motor, which is fixedly connected to the bottom wall of the processing barrel. The output shaft of the drive motor is fixedly connected to a rotating shaft, and a spiral auger is fixedly connected above the outer surface of the rotating shaft. The spiral auger is located inside the feeding pipe, and the size of the spiral auger is adapted to the inner diameter of the feeding pipe.
[0008] Preferably, a fixed frame is rotatably connected to the top end of the rotating shaft, and the outer surface of the fixed frame is fixedly connected to the inner wall of the feeding hopper.
[0009] Preferably, the outer surface of the feeding barrel is fixedly connected with several fixing rods, and the other end of each fixing rod is fixedly connected to the upper surface of the processing barrel.
[0010] Preferably, the screening assembly includes a first screen plate and a second screen plate, which are placed inside the processing barrel from top to bottom. Both the first and second screen plates are sleeved with a rotating shaft. Elastic steel plates are fixedly connected to the upper surface of the first screen plate and the bottom surface of the second screen plate. The other end of the upper elastic steel plate is fixedly connected to the top wall of the processing barrel, and the other end of the lower elastic steel plate is fixedly connected to the bottom wall of the processing barrel. Several circumferentially distributed mounting rods are fixedly connected between the adjacent sides of the two first screen plates. A collision ball is fixedly connected to the adjacent end of each group of mounting rods. Several circumferentially distributed connecting rods are fixedly connected to the middle of the outer surface of the rotating shaft. A striking ball is fixedly connected to the distant end of each of the connecting rods. The position of each striking ball corresponds to the position of each group of collision balls.
[0011] Preferably, both the collision ball and the striking ball have smooth outer surfaces.
[0012] Preferably, the upper surfaces of the first sieve plate and the second sieve plate are provided with two guide grooves, and each guide groove is fitted with a guide rod. The other ends of the two guide rods located at the top are fixedly connected to the top wall of the processing barrel, and the two guide rods located at the bottom are fixedly connected to the bottom wall of the processing barrel.
[0013] Preferably, a motor protective cover is fixedly connected to the bottom wall of the processing barrel, and the motor protective cover is sleeved with the output shaft of the drive motor.
[0014] This utility model has at least the following beneficial effects:
[0015] 1. When screening alumina hollow spheres, first place the processed alumina hollow spheres into the feeding hopper. Then, turn on the power switch connected to the drive motor, which will cause the output shaft of the drive motor to rotate. This will drive the rotating shaft fixedly connected to the output shaft of the drive motor to rotate synchronously. When the rotating shaft rotates, the auger fixedly connected to the outer surface of the rotating shaft will rotate synchronously. When the auger rotates, it will transport the material inside the feeding hopper to the processing hopper through the auger. By setting a fixed frame rotatably connected to the upper surface of the rotating shaft, the rotation of the rotating shaft can be made more stable, and further, the rotation of the auger can be made more stable.
[0016] By setting up a feeding component, the feeding speed can be made more uniform when conveying materials inside the feeding hopper, and the jamming of materials during feeding can be avoided.
[0017] 2. When the material inside the feeding hopper is conveyed to the processing hopper by the auger, the material inside the auger first enters above the first screen plate. At this time, the rotating shaft rotates slowly and continuously, causing the auger to feed the material inside the feeding hopper. When the rotating shaft rotates, the connecting rod drives the striking ball to make a circular motion. When the striking ball rotates, it will collide with the upper and lower collision balls. At this time, the first and second screen plates can be shaken up and down. The elastic steel plate can make the first and second screen plates automatically reset when shaking. With the guidance of the guide groove and guide rod, the first and second screen plates can be prevented from tilting and getting stuck during operation. When the first and second screen plates vibrate continuously, they will screen the material inside the processing hopper. At this time, the broken hollow balls will remain above the first screen plate, and the smaller fragments will flow to the bottom of the second screen plate, thus achieving the purpose of screening.
[0018] By setting up screening components, hollow sphere materials can be subjected to secondary screening, thereby achieving better screening results. Attached Figure Description

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.
[0025] Please see Figures 1-4 This utility model provides a technical solution:
[0026] Example 1: A hollow ball screening machine with a spiral propulsion structure includes a processing barrel 3, a feeding barrel 4 placed on top of the processing barrel 3, a feeding pipe 5 fixedly connected to the bottom surface of the feeding barrel 4, the feeding pipe 5 being fixedly connected to the processing barrel 3, a feeding assembly 1 installed inside the feeding pipe 5, the feeding assembly 1 being used for spiral feeding of materials inside the feeding barrel 4, the feeding assembly 1 ensuring more uniform feeding of materials into the feeding barrel 4 and preventing feeding jamming, and a screening assembly 2 installed inside the processing barrel 3, the screening assembly 2 being used for screening the materials fed into the feeding barrel 4.
[0027] The feeding assembly 1 includes a drive motor 6, which is fixedly connected to the bottom wall of the processing barrel 3. The output shaft of the drive motor 6 is fixedly connected to a rotating shaft 7. A spiral auger 8 is fixedly connected above the outer surface of the rotating shaft 7. The spiral auger 8 is located inside the feeding pipe 5, and the size of the spiral auger 8 is adapted to the inner diameter of the feeding pipe 5.
[0028] A fixed frame 9 is rotatably connected to the top of the rotating shaft 7, and the outer surface of the fixed frame 9 is fixedly connected to the inner wall of the feeding barrel 4.
[0029] Several fixing rods 10 are fixedly connected to the outer surface of the feeding barrel 4, and the other end of each fixing rod 10 is fixedly connected to the upper surface of the processing barrel 3.
[0030] When screening alumina hollow spheres, the processed alumina hollow spheres are first placed inside the feeding hopper 4. At this time, the power switch connected to the drive motor 6 is turned on, which allows the output shaft of the drive motor 6 to rotate. This drives the rotating shaft 7, which is fixedly connected to the output shaft of the drive motor 6, to rotate synchronously. When the rotating shaft 7 rotates, the spiral auger 8, which is fixedly connected to the outer surface of the rotating shaft 7, rotates synchronously. When the spiral auger 8 rotates, it transports the material inside the feeding hopper 4 to the processing hopper 3. By setting a fixed frame 9 that is rotatably connected to the upper surface of the rotating shaft 7, the rotation of the rotating shaft 7 can be made more stable, and the rotation of the spiral auger 8 can be made more stable.
[0031] By setting up the feeding component 1, the feeding speed can be made more uniform when conveying materials inside the feeding hopper 4, and the jamming of materials during feeding can be avoided.
[0032] Example 2: Screening assembly 2 includes a first screen plate 11 and a second screen plate 12. The first screen plate 11 and the second screen plate 12 are placed inside the processing barrel 3 from top to bottom. Both the first screen plate 11 and the second screen plate 12 are sleeved with the rotating shaft 7. The upper surface of the first screen plate 11 and the bottom surface of the second screen plate 12 are fixedly connected to elastic steel plates 13. The other end of the upper elastic steel plate 13 is fixedly connected to the top wall of the processing barrel 3, and the other end of the lower elastic steel plate 13 is fixedly connected to the bottom wall of the processing barrel 3. Several circumferentially distributed mounting rods 14 are fixedly connected between the sides of the two first screen plates 11 that are close to each other. The close ends of each set of mounting rods 14 are fixedly connected to collision balls 15. Several circumferentially distributed connecting rods 16 are fixedly connected to the middle of the outer surface of the rotating shaft 7. The distant ends of the connecting rods 16 are fixedly connected to striking balls 17. The position of each striking ball 17 corresponds to the position of each set of collision balls 15.
[0033] Both the collision ball 15 and the striking ball 17 have smooth outer surfaces.
[0034] Two guide grooves 18 are provided on the upper surfaces of the first screen plate 11 and the second screen plate 12. Each guide groove 18 is fitted with a guide rod 19. The other ends of the two upper guide rods 19 are fixedly connected to the top wall of the processing barrel 3, and the two lower guide rods 19 are fixedly connected to the bottom wall of the processing barrel 3.
[0035] A motor protective cover 20 is fixedly connected to the bottom wall of the processing barrel 3, and the motor protective cover 20 is sleeved with the output shaft of the drive motor 6.
[0036] When the material inside the feeding hopper 4 is conveyed to the processing hopper 3 by the auger 8, the material inside the auger 8 first enters above the first screen plate 11. At this time, the rotating shaft 7 rotates slowly to feed the material inside the feeding hopper 4 by the auger 8. When the rotating shaft 7 rotates, the connecting rod 16 drives the striking ball 17 to make a circular motion. When the striking ball 17 rotates, it will collide with the upper and lower collision balls 15. At this time, the first screen plate 11 and the second screen plate 12 can be shaken up and down by the set elasticity. The steel plate 13 allows the first screen plate 11 and the second screen plate 12 to automatically reset when shaking. With the guidance of the guide groove 18 and the guide rod 19, the first screen plate 11 and the second screen plate 12 can be prevented from tilting and getting stuck during operation. When the first screen plate 11 and the second screen plate 12 vibrate continuously, they will screen the material inside the processing barrel 3. At this time, the broken hollow ball will remain above the first screen plate 11, and the smaller fragments will flow into the lower part of the second screen plate 12, thereby achieving the purpose of screening.
[0037] By setting up screening component 2, a secondary screening function can be performed on hollow sphere materials, thereby achieving a better screening effect.
