However, this structure is relatively complex, and the gaps at the corners are small, making it easy for material to get stuck in the gaps. This part of the material is inconvenient to clean, and there is room for improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a vacuum drying device suitable for PPS crosslinking and mixing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vacuum drying device suitable for PPS crosslinking and mixing, comprising a base and a material tank, wherein the material tank is located on top of the base, and an auxiliary component is installed inside the material tank.

A flange ring adapted to the connecting ring is provided on the outer circumference of the material tank. Several through holes are provided inside the connecting ring and the flange ring. A reinforcing plate is fixedly connected to the side of each baffle that is far away from each other, and the reinforcing plates are all in contact with the inner wall of the material tank.

[0007] The baffle can be moved to the discharge tank as needed. During the movement, the material adhering to the outside of the baffle will be cleaned, and the cleaning of the inner wall of the tank will be more convenient. When the tank is tilted, the baffle inside will also be moved synchronously. The baffle can bring the material at the bottom to the top position, and then fall to the top of the material along the slope of the baffle, which helps to improve the flowability of the material and make the material heat evenly. After the drying work is completed, the bolts of the fixing connecting ring can be removed, and the connecting ring will no longer be restricted. By moving the connecting ring with the handle and the baffle outward, the groove connecting the tank and the baffle can scrape off the material at the corner. There is no longer any obstruction on the inner wall of the tank, which is convenient for cleaning.

[0008] As a further preferred embodiment of this technical solution, a tilting assembly is installed on the outside of the material tank.

When the tank is flipped, the baffle inside will also be moved synchronously. The baffle can bring the material at the bottom to the top position and then fall to the top of the material along the slope of the baffle, which is conducive to improving the fluidity of the material and making the material heated evenly. After the drying work is completed, the bolts of the fixed connecting ring are removed, and the connecting ring will no longer be restricted. By driving the connecting ring with the handle and moving the baffle outward, the groove connecting the tank and the baffle can scrape off the material at the corner position. There is no longer any obstruction on the inner wall of the tank, which is convenient for cleaning.

[0017] (2) By setting up a turning component, this utility model ensures that the material is turned evenly while the state of the material tank is stable enough.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 and Figure 3 As shown in this embodiment, a vacuum drying device suitable for PPS crosslinking and mixing includes a base 1 and a material tank 3. The material tank 3 is located on top of the base 1. An auxiliary component 5 is installed inside the material tank 3. The auxiliary component 5 includes several baffles 502 that are slidably inserted inside the material tank 3. The baffles 502 near the outside are fixedly connected to the same connecting ring 501. A flange ring 503 adapted to the connecting ring 501 is provided on the outer circumference of the material tank 3. Several through holes are opened inside the connecting ring 501 and the flange ring 503. A reinforcing plate 504 is fixedly connected to the side of the several baffles 502 that is far away from each other, and the several reinforcing plates 504 are all in contact with the inner wall of the material tank 3.

[0025] When the material tank 3 is tilted, the baffle 502 inside it will also move synchronously. The baffle 502 can bring the material at the bottom to the top position, and then fall to the top of the material along the slope of the baffle 502. This helps to improve the flowability of the material and make the material heat up evenly. After the drying work is completed, the bolts fixing the connecting ring 501 can be removed. The connecting ring 501 will no longer be restricted. By moving the connecting ring 501 and the baffle 502 outward by the handle, the groove connecting the material tank 3 and the baffle 502 can scrape off the material at the corner. There is no longer any obstruction on the inner wall of the material tank 3, making cleaning more convenient.

[0026] like Figure 1 and Figure 3 As shown, a tilting assembly 7 is installed on the outside of the material tank 3. The tilting assembly 7 includes two support rings 701 that are rotated and sleeved on the outside of the material tank 3 through bearings. A horizontally arranged motor 703 is fixedly installed inside one of the support rings 701. A gear 704 is coaxially fixed at the output end of the motor 703. A toothed ring 702 is coaxially fixed on the outside of the material tank 3. The gear 704 meshes with the toothed ring 702.

[0027] The motor 703, which is fixed at the bottom of the support ring 701, is started. The motor 703 drives the gear 704 to start rotating. The gear 704 drives the gear ring 702 to rotate through meshing. The gear ring 702 drives the material tank 3 to tumble, and the material will be driven to flow. With the help of the electric heating tube inside the installation sleeve 2, the material will be evenly radiated with heat.

[0028] like Figure 2 and Figure 4 As shown, a discharge assembly 6 is installed between the base 1 and the material tank 3. The discharge assembly 6 includes a support plate 605 hinged to the top of the base 1. Two support rings 701 are fixedly connected to the top outer wall of the support plate 605. A vertically arranged hydraulic cylinder 606 is fixedly installed on the bottom inner wall of the base 1. A horizontally arranged drive ring 607 is fixedly connected to the output end of the hydraulic cylinder 606. A horizontally arranged mounting column 608 is fixedly connected inside the support plate 605. The drive ring 607 is slidably sleeved on the outside of the mounting column 608.

[0029] A cylinder 601 is fixedly installed on the outer wall of both ends of the base 1 by a support frame. A connecting frame 602 is fixedly connected to the output end of each cylinder 601. The same reinforcing plate 604 is fixedly connected to the two connecting frames 602. A cover 603 is rotatably connected inside the reinforcing plate 604. The cover 603 is fitted outside the opening of the material tank 3.

[0030] The two cylinders 601 are controlled to operate synchronously, and the two connecting frames 602 are driven to move away from the material tank 3 synchronously. The two connecting frames 602 drive the reinforcing plate 604 and the cover 603 to move synchronously, and the opening of the material tank 3 will be exposed. The material will flow outward through the opening. Then, the hydraulic cylinder 606 is started, and the drive ring 607 is driven to move upward. The drive ring 607 drives one end of the support plate 605 to move upward through the mounting column 608, so that the tilt angle of the material tank 3 increases, thereby ensuring that the material can be completely discharged.

[0031] like Figure 1 As shown in Figure 2, the top of the support plate 605 is fixedly connected to the mounting sleeve 2. Several equally spaced electric heating tubes are installed inside the mounting sleeve 2. The electric heating tubes inside the mounting sleeve 2 emit heat, and the material will be uniformly radiated with heat.

[0032] like Figure 2 and Figure 3 As shown, an air extraction pipe 4 is rotatably connected inside the cover 603. The air extraction pipe 4 is fixed inside the reinforcing plate 604 by a bracket, and a filter sleeve is provided at one end of the air extraction pipe 4 inside the material tank 3. The air inside the material tank 3 is extracted by an external vacuuming device through the air extraction pipe 4 to create a vacuum environment for the material.

[0033] like Figure 3As shown, each of the several baffles 502 has a positioning protrusion 505 near one end of the cover 603, and the outer wall of one end of the cover 603 has several slots that fit the positioning protrusions 505. This can improve the stability of the moving end of the baffle 502 and ensure that the cover 603 will not shake at will.

[0034] This invention provides a vacuum drying device suitable for PPS crosslinking and mixing, the specific working principle of which is as follows:

[0035] When the device is working, adjust the position of the material tank 3 so that its feeding port is moved to the highest point. Then, use the feeding machine to introduce the material into the material tank 3 through the feeding port, and then seal the feeding port opening. Then, use the external vacuum equipment to extract the air from the inside of the material tank 3 through the air extraction pipe 4 to create a vacuum environment for the material. Start the motor 703 fixed at the bottom of the support ring 701. The motor 703 drives the gear 704 to start rotating. The gear 704 drives the gear ring 702 to rotate through meshing. The gear ring 702 drives the material tank 3 to tumble, and the material will be driven to flow. With the help of the electric heating tube inside the installation sleeve 2, the material will be evenly radiated with heat. When the material tank 3 is tilted, the baffle 502 inside it will also move synchronously. The baffle 502 can bring the material at the bottom to the top position, and then fall to the top of the material along the slope of the baffle 502. This helps to improve the flowability of the material and make the material heat up evenly. After the drying work is completed, the bolts fixing the connecting ring 501 can be removed. The connecting ring 501 will no longer be restricted. By moving the connecting ring 501 and the baffle 502 outward by the handle, the groove connecting the material tank 3 and the baffle 502 can scrape off the material at the corner. There is no longer any obstruction on the inner wall of the material tank 3, making cleaning more convenient. The discharge process is as follows: control two cylinders 601 to operate synchronously, and two connecting frames 602 are driven to move away from the material tank 3 synchronously. The two connecting frames 602 drive the reinforcing plate 604 and the cover 603 to move synchronously, and the opening of the material tank 3 will be exposed. The material will flow outward through the opening. Then, control the hydraulic cylinder 606 to start, and drive the drive ring 607 to move upward. Drive ring 607 drives one end of support plate 605 to move upward through mounting column 608, so that the tilt angle of material tank 3 increases, thereby ensuring that the material can be completely discharged.

[0036] 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.
