Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of pulverizer, in particular, to an airflow pulverizer capable of automatic feeding. BACKGROUND

[0002] The airflow pulverizer capable of automatic feeding carries material particles at high speed by airflow, so that the material particles collide and rub with each other, thereby achieving the purpose of pulverization. In this process, the automatic feeding device can continuously and stably deliver the material into the pulverization cavity according to the set parameters such as feeding speed and feeding amount, thereby ensuring the continuity and stability of the pulverization process.

[0003] Due to the factors such as humidity, particle size and viscosity of some materials, when the operator delivers the material to be pulverized into the airflow pulverizer, the material may stick to the inner wall of the delivery pipeline or accumulate and stick together in the storage bin, making it difficult to deliver the material normally. Therefore, the operator often needs to shut down the airflow pulverizer, check the accumulation position, manually remove the accumulated material, and then open the airflow pulverizer and directly add the material into the airflow pulverizer. During the shutdown and maintenance of feeding, the entire production process is interrupted. For large-scale production or production tasks with high continuity requirements, frequent shutdown and restart will affect the pulverization efficiency of the airflow pulverizer and increase the production cycle.

[0051] As shown in Figures 1-4 The present disclosure shows an embodiment of an automatic feeding airflow crusher, which comprises a body 1 and a discharge pipe 2, the discharge pipe 2 is in communication with the outer wall of the body 1, the outer wall of the body 1 near the bottom is fixedly connected with a base 3, the outer wall of the body 1 is communicated with an air guide pipe 4, further comprising a spiral blade 5, a rotating mechanism, a storage mechanism and a dispersion mechanism, the spiral blade 5 is arranged above the body 1, the spiral blade 5 is used for conveying materials into the body 1, the rotating mechanism is arranged on the spiral blade 5, the rotating mechanism is used for driving the spiral blade 5 to rotate, the storage mechanism is arranged at the top of the body 1, the storage mechanism is used for pre-storing materials, the dispersion mechanism is arranged on the rotating mechanism, the dispersion mechanism is used for dispersing and discharging the materials conveyed by the spiral blade 5, and the bottom of the body 1 is detachably connected with a bottom plate 23.

[0052] First, the operator will first take the material to be crushed to the workshop, and store it using the storage mechanism, the storage mechanism comprises a cover plate 6, a storage frame 7 and a support assembly, the cover plate 6 is detachably connected to the top of the body 1, and the top of the cover plate 6 is provided with a feeding port, the storage frame 7 is fixedly connected to the top of the cover plate 6, and the support assembly is arranged on the inner wall of the storage frame 7, the support assembly comprises a support rod 8 and a support plate 9, the support rod 8 is fixedly connected to the inner wall of the storage frame 7, and the support plate 9 is fixedly connected to the other end of the support rod 8, by placing the material to be crushed into the storage frame 7, a small part of the material in the storage frame 7 will slowly flow into the body 1 through the feeding port.

[0053] The remaining sticky material needs to be conveyed and discharged by rotating mechanism. The rotating mechanism comprises motor 10, rotating ring 11, rotating shaft 12, fixed column 13, connecting column 14, fixed block 15 and scraping assembly. The motor 10 is installed on the top of the support plate 9. The rotating ring 11 is coaxially connected with the output end of the motor 10. The rotating shaft 12 is fixedly connected with the other end of the rotating ring 11, and the spiral blade 5 is fixedly connected with the outer wall of the rotating shaft 12. The fixed column 13 is fixedly connected with the bottom of the cover plate 6. The connecting column 14 is fixedly connected with the outer wall of the fixed column 13. The fixed block 15 is fixedly connected with the other end of the connecting column 14, and the rotating groove is formed in the fixed block 15. The end of the rotating shaft 12 away from the motor 10 is rotatably connected in the rotating groove. The scraping assembly is arranged on the outer wall of the rotating ring 11. By starting the motor 10, the motor 10 drives the rotating ring 11 and the rotating shaft 12 to rotate in the rotating groove. At this time, the spiral blade 5 fixedly connected with the outer wall of the rotating shaft 12 also rotates. In the process of rotation, the spiral blade 5 will convey the material into the machine body 1 along the blade angle of the spiral blade 5.

[0054] At this time, some sticky material will be attached to the inner wall of the storage frame 7, which needs to be scraped by the scraping assembly. The scraping assembly comprises vertical rod 16, inclined rod 17 and scraper 18. The vertical rod 16 is fixedly connected with the outer wall of the rotating ring 11. The inclined rod 17 is fixedly connected with the other end of the vertical rod 16. The scraper 18 is fixedly connected with the other end of the inclined rod 17. The scraper 18 is close to the inner wall of the storage frame 7. The purpose is that part of the material is sticky and will be attached to the inner wall of the storage frame 7. Therefore, the motor 10 drives the scraper 18 to scrape the inner wall of the storage frame 7. The material attached to the inner wall of the storage frame 7 is scraped off by the scraper 18 and conveyed into the machine body 1 by the spiral blade 5. By starting the motor 10, the vertical rod 16 fixedly connected with the rotating ring 11 drives the inclined rod 17 and the scraper 18 to rotate around the inner wall of the storage frame 7. At this time, the scraper 18 will be close to the inner wall of the storage frame 7 to scrape off the material on the inner wall of the storage frame 7. The scraped material will be conveyed into the machine body 1 by the spiral blade 5.

[0055] Since the material is prevented from being transported into the body 1 by being stacked together, the material transported by the spiral blade 5 is dispersed and discharged using a dispersion mechanism, which includes a second motor 19, a fixed rod 20 and a dispersion disc 21. The second motor 19 is installed at the bottom of the fixed block 15, the fixed rod 20 is coaxially connected with the output end of the second motor 19, and the dispersion disc 21 is fixedly connected to the other end of the fixed rod 20. After the material passes through the spiral blade 5, it will fall into the dispersion disc 21. The second motor 19 is started to drive the fixed rod 20 and the dispersion disc 21 to rotate back and forth. The second motor 19 is set as a forward and reverse motor. The use of the forward and reverse motor can enhance the dispersion force of the dispersion disc 21. Through forward rotation and reverse rotation, the material can be dispersed and discharged outward, avoiding a large group of material directly falling into the body 1. In addition, the top of the dispersion disc 21 is provided with an arc surface 22 to avoid clogging caused by the material accumulated in the dispersion disc 21.

[0056] It should be noted that the detachable connection structure used in the embodiment is a flange bolt connection. The flange of the bottom plate 23 is matched with the flange at the bottom of the body 1, and the locking bolt 24 is used to tightly connect the bottom plate 23 and the body 1. When the body 1 needs to be opened, the locking bolt 24 is loosened, the bottom plate 23 is removed, and the material accumulated at the bottom of the body 1 is discharged outward. After the flange of the cover plate 6 is matched with the flange at the top of the body 1, the locking bolt 24 is used to tightly connect the cover plate 6 and the body 1. When the body 1 needs to be opened for internal inspection, the locking bolt 24 is loosened, the cover plate 6 is removed, and the internal part of the body 1 is inspected.

[0057] Working principle: when the airflow pulverizer is used to pulverize the material, the operator will first put the material into the storage frame 7, and then start the first motor 10 to drive the spiral blade 5 to rotate, so that the material in the storage frame 7 can be transported into the body 1 through the blade angle of the spiral blade 5. Start the air guide pipe 4 to inflate the body 1, and wait for the material to collide with the intersecting gas to be pulverized. While the spiral blade 5 transports the material, the scraper 18 will also scrape the inner wall of the storage frame 7 along with the rotation of the first motor 10, and the scraped material will be transported into the dispersion disc 21 through the spiral blade 5. Start the second motor 19 to drive the dispersion disc 21 to disperse and discharge the material, and make the second motor 19 rotate forward and then reverse, so as to swing the material on the dispersion disc 21 into the body 1. At this time, the material falling into the body 1 will contact the intersecting gas flow, and the gas flow will pulverize the material. The pulverized material is transported outward through the discharge pipe 2. After this batch of material is pulverized, new material can be continuously poured into the storage frame 7 for automatic discharging and pulverizing.

[0058] It should be noted that the above examples are only used to illustrate the technical solutions of the present disclosure rather than limit the present disclosure. Although the present disclosure is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and all should be covered in the scope of the claims of the present disclosure.
