Description

Technical Field

[0001] This utility model relates to the field of PAEK production, specifically to a soluble PAEK production equipment. Background Technology

[0002] PAEK production equipment is a specialized device for manufacturing polyaryletherketones. Polyaryletherketones are a type of crystalline polymer composed of phenylene rings linked by oxygen bridges and carbonyl groups. They have excellent heat resistance, mechanical strength, and chemical stability. In the production process, the crushing device is an important component of the equipment, used to crush the polymerized PAEK material into particles or powders suitable for subsequent processing, facilitating transportation, storage, and further molding.

[0003] Chinese patent CN117244650A discloses a continuous crushing device for the production of polyaryletherketone polymers, including a crossbar and a rotating rod. A second belt is fitted on the outer wall of both the rotating rod and the crossbar. Two cams are fixedly connected to the outer wall of the crossbar. A guide rod is fixedly connected to the bottom of the filter screen. The guide rod is inserted into the discharge hopper of the polyaryletherketone polymer. The polyaryletherketone polymer can be crushed by the cooperation of the cutting blade and the crushing roller. The rotation of the cams can drive the filter screen to move up and down, avoiding clogging of the filter screen and achieving a good crushing effect on the polyaryletherketone polymer.

[0004] In the continuous crushing device for producing polyaryletherketone polymers mentioned above, during the production process, when the crushed material is crushed and falls from a pair of crushing rollers, the crushed material sticks together due to the squeezing of the pair of crushing rollers, making it difficult to pass directly through the filter screen. The material passes through the filter screen excessively by the rotation of the cam, which is not convenient for the material to be discharged. The crushed material is easy to be repeatedly transported and crushed. Utility Model Content

[0005] The purpose of this invention is to provide a soluble PAEK production device that uses a stirring paddle to agitate a pair of crushing rollers to crush the material, so that the material is completely dispersed after crushing. Finally, a screw rod limits the falling speed of the granular material, so that the completely dispersed material contacts the filter screen at a uniform speed, reducing the probability of crushed material accidentally falling into the secondary collection box, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a soluble PAEK production device, comprising a shell, a main storage box at the lower end of the shell, a filter screen at the upper end of the main storage box, a collection frame in the middle of the shell, a dispersing bucket at the lower end of the collection frame, the dispersing bucket and the collection frame being sealed together by a first pipe, a first bevel gear in the middle of the dispersing bucket, a second bevel gear on one side of the lower end of the first bevel gear, and a stirring paddle at the lower end of the second bevel gear.

[0007] Preferably, a second pipe is provided at the lower end of the dispersing bucket facing the filter screen.

[0008] Preferably, a helical rod is provided through the interior of the second pipe.

[0009] Preferably, the upper end of the auger is welded and fixed to the lower end of the agitator, and the second bevel gear is meshed with the first bevel gear.

[0010] Preferably, the upper end of the first bevel gear is covered with a protective cover, and the protective cover is welded and fixed to the inner wall of the dispersing barrel.

[0011] Preferably, the stirring paddle and the screw rotate clockwise.

[0012] Preferably, crushing rollers are provided on both sides of the upper end of the second pipe.

[0013] Preferably, a feeding port is provided at the upper end between the two crushing rollers.

[0014] Preferably, the collection frame is rectangular and completely covers the gap between a pair of crushing rollers.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] After the material is pulverized by the rotation of a pair of crushing rollers, the material is first collected by the collection frame and uniformly transported to the dispersing bucket. The material stored in the dispersing bucket can be dispersed by the rotation of the stirring paddle. The dispersing and the spiral rod limit the falling speed of the granular material, so that the granular material slowly and in small amounts comes into contact with the filter screen. This ensures that the pulverized material fully contacts and passes through the filter screen, preventing the material from sticking together and piling up in large quantities to contact the filter screen, and preventing qualified material from accidentally falling into the secondary collection box.

[0023] The present invention will be further described below with reference to specific embodiments.

[0024] Example 1

[0025] like Figure 1 As shown, a soluble PAEK production device in this embodiment includes a shell 1. A main storage box 4 is provided at the lower end of the shell 1. A secondary storage box 3 is provided on both sides of the main storage box 4. After filtration, the material with the correct diameter will fall directly into the main storage box 4, while the material with the incorrect diameter will spread to both sides and fall into the secondary storage box 3.

[0026] In order to facilitate the diversion and collection of crushed materials, a filter screen 15 is provided at the upper end of the main collection box 4. Guide plates 16 are provided on both sides of the filter screen 15, and the guide plates 16 are welded and fixed to the filter screen 15. The guide plates 16 extend to the upper end of the secondary collection box 3. Materials that cannot pass through the filter screen 15 will be guided by the guide plates 16 and transferred to the upper end of the secondary collection box 3. A vibration motor 5 is provided at the front end of the outer shell 1. The start of the vibration motor 5 can provide vibration, which can facilitate the material to fall from the upper end of the guide plates 16 and also facilitate the dispersal of materials inside the dispersing bucket 8, thereby improving the operating effect and production efficiency of the equipment.

[0027] Additionally, a rectangular collection frame 7 is provided in the middle of the interior of the outer casing 1. The collection frame 7 completely covers the gap between the pair of crushing rollers 6, and the rectangular collection frame 7 can completely collect the material that falls off after being crushed by the pair of crushing rollers 6. Figure 2As shown, a dispersing bucket 8 is provided at the lower end of the collection frame 7. The middle position of the dispersing bucket 8 and the collection frame 7 is sealed and connected by the first pipe 9. The vibration of the vibration motor 5, combined with the weight of the material itself, will cause the material collected by the collection frame 7 to converge and fall into the dispersing bucket 8.

[0028] To prevent the material pulverized by the pair of crushing rollers 6 from sticking together due to the clamping of the crushing rollers 6, such as Figure 3 and Figure 4 As shown, a first bevel gear 11 is provided in the middle of the inside of the dispersing tank 8, and a second bevel gear 13 is provided on one side of the lower end of the first bevel gear 11. The second bevel gear 13 is meshed with the first bevel gear 11. A stirring paddle 12 is provided at the lower end of the second bevel gear 13. The material gathered inside the dispersing tank 8 can be dispersed inside the dispersing tank 8 after being stirred by the stirring paddle 12, and the dispersing is prepared for subsequent filtration by the filter screen 15.

[0029] In order to avoid the material affecting the meshing between the first bevel gear 11 and the second bevel gear 13, the upper end of the first bevel gear 11 is covered with a protective cover 10, and the protective cover 10 is welded and fixed to the inner wall of the dispersing bucket 8. By covering the first bevel gear 11 and the second bevel gear 13 with the protective cover 10, the meshing connection can be prevented from being affected by the debris, thus improving the stability of the transmission structure.

[0030] To ensure that the particulate material falls steadily onto the upper part of the filter screen 15, a second pipe 17 is provided at the lower end of the dispersing bucket 8 facing the filter screen 15. The second pipe 17 is welded and fixed to the dispersing bucket 8. The material dispersed by the rotation of the stirring paddle 12 is gathered through the second pipe 17 and falls uniformly into the center of the filter screen 15, preventing the particulate material from splashing directly to the surrounding area of ​​the filter screen 15.

[0031] In addition, in order to allow the granular material to accumulate inside the dispersing bucket 8 for a longer period of time, and also to limit the speed at which the granular material falls from the second pipe 17, such as Figure 5 As shown, a spiral rod 14 is installed through the interior of the second pipe 17, and the upper end of the spiral rod 14 is welded and fixed to the lower end of the stirring paddle 12. While the stirring paddle 12 is transmitting and rotating to agitate the material, the rotation of the spiral rod 14 will limit the speed at which the granular material falls.

[0032] Furthermore, the stirring paddle 12 and the screw rod 14 rotate clockwise. The clockwise rotating screw rod 14 can push the granular material vertically upward, further limiting the falling speed of the granular material, so that the granular material inside the dispersing tank 8 falls slowly and uniformly, avoiding a large amount of granular material falling onto the surface of the filter screen 15 at the same time.

[0033] Crushing rollers 6 are installed on both sides of the upper end of the second pipe 17. The two crushing rollers 6 rotate relative to each other. The crushing of granular materials can be achieved by the relative rotation of the two crushing rollers 6. A feeding port 2 is provided at the upper end between the two crushing rollers 6. The feeding port 2 penetrates and extends to both the inner and outer ends of the outer shell 1. The PAEK material to be crushed and processed is fed into the equipment through the feeding port 2 and comes into contact with the rotation of the crushing rollers 6.

[0034] Working principle: The device crushes soluble PAEK for subsequent processing. Particles are fed into the outer shell 1 through the feed port 2. The material falls between a pair of crushing rollers 6, and the relative rotation of the two rollers crushes the material. The crushed material is collected by the collection frame 7 and transported to the dispersing tank 8 through the first pipe 9. The vibration motor 5 is started, generating vibration. This starts the motor at one end of the first bevel gear 11. The first bevel gear 11 can drive the stirring paddle 12 and the screw rod 14 to rotate via the second bevel gear 13, initially stirring... The rotation of paddle 12 can agitate and break up the material inside the crushing barrel 8. Secondly, the rotation of screw rod 14 will give the material an upward force. The weight of the crushed material itself, combined with the rotation of screw rod 14, will cause the crushed material to be discharged from the second pipe 17 at a uniform speed and slowly. After being discharged, it falls on the upper end of filter screen 15. After being filtered by filter screen 15, the material with the correct diameter will fall into the main collection box 4, while the material with the incorrect diameter will slide along the guide plate 16 and fall into the secondary collection box 3. The material in the secondary collection box 3 can be repeatedly fed into the feeding port 2 to complete the repeated crushing.
