For materials with melting points higher than room temperature, pump jamming is likely to occur, which cannot meet the transportation needs of materials with high melting points. This leads to easy damage to the discharge pump and affects the transportation efficiency. Utility Model Content

[0009] Preferably, one end of the first connecting shaft passes through one side of the rear cover plate, and an inner rotor is mounted on the outside of the first connecting shaft.
[0010] Preferably, an isolation sleeve is installed on the outside of the inner rotor.
[0011] Preferably, a pressure plate is installed on one side of the rear cover plate, and one end of the first connecting shaft passes through one side of the pressure plate.

[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0026] Example 1: As Figure 1-Figure 5As shown, this utility model provides a high-vacuum magnetic discharge pump with a jacket design, including a discharge pump assembly 1. The discharge pump assembly 1 includes a pump body shell 11 and fixing screws 112. A material conveying port 116 is provided on one side of the pump body shell 11. Sealing covers 12 are installed on both sides of the middle of the pump body shell 11. A first connecting shaft 19 is rotatably connected between the two sealing covers 12. One end of the first connecting shaft 19 passes through one side of the sealing cover 12. A driving gear 110 is fixedly connected to the outside of the first connecting shaft 19. A driven gear 114 meshes with one side of the driving gear 110. A second connecting shaft 115 is fixedly connected to the middle of the driven gear 114. The end of the second connecting shaft 115 is rotatably connected to the sealing cover 12. A jacket mechanism 2 is installed inside the pump body shell 11. The jacket mechanism 2 includes a fixed cavity 21, which is opened inside the pump body shell 11. A fixing plate 22 is fixedly connected inside the fixed cavity 21. One side of the fixing plate 22 is fixedly connected to the fixed plate 22. A first conveying pipe 23 and a second conveying pipe 24 are fixedly connected. Both ends of the first conveying pipe 23 and the two ends of the second conveying pipe 24 pass through one side of the pump body housing 11. A front cover plate 111 is installed on one side of the pump body housing 11 by fixing screws 112, and a rear cover plate 13 is installed on the other side of the pump body housing 11 by fixing screws 112. A second rubber ring 113 is installed between the pump body housing 11 and the front cover plate 111, and a first rubber ring 17 is installed between the pump body housing 11 and the rear cover plate 13. Bushings 18 are provided on both sides of the driving gear 110 and both sides of the driven gear 114. The four bushings 18 are respectively fitted on the outside of the first connecting shaft 19 and the outside of the second connecting shaft 115. One end of the first connecting shaft 19 passes through one side of the rear cover plate 13, and an inner rotor 14 is installed on the outside of the first connecting shaft 19. An isolation sleeve 16 is installed on the outside of the inner rotor 14. A pressure plate 15 is installed on one side of the rear cover plate 13, and one end of the first connecting shaft 19 passes through one side of the pressure plate 15.
[0027] The rear cover plate 13, pump body housing 11, and front cover plate 111 are installed sequentially using fixing screws 112. Two sealing covers 12 are fixed to the middle sides of the pump body housing 11, creating a sealed space inside. A motor drives the magnetic coupling to rotate, causing the first connecting shaft 19 and the drive gear 110 to rotate. The drive gear 110 meshes with the driven gear 114, driving the driven gear 114 to rotate. This rotation moves the material from one end of the material conveying port 116 to the other, achieving the purpose of material conveying. During material conveying, a fixed cavity 21 is provided inside the pump body housing 11, and the first conveying pipe 23 and the second conveying pipe are installed inside the fixed cavity 21. 24. The two ends of the first conveying pipe 23 and the second conveying pipe 24 are respectively connected to the inlet and outlet of the heat transfer oil circulation device, and the heat transfer oil conveying directions of the first conveying pipe 23 and the second conveying pipe 24 are opposite, thereby improving the efficiency of heat transfer oil circulation heating inside the fixed cavity 21, ensuring that the high melting point material inside the pump body shell 11 remains in a liquid state and does not solidify. The active gear 110 and the second connecting shaft 115 are made of high-strength PEEK material, which not only has high hardness but also high temperature resistance. The materials of the discharge pump assembly 1 can meet the high temperature of over 200 degrees, ensuring that the material can be discharged smoothly not only under high vacuum, but also for high melting point materials, effectively increasing the application range of the discharge pump.
[0028] Example 2: Figure 3 and Figure 5 As shown, a positioning mechanism 3 is installed on one side of the pressure plate 15. The positioning mechanism 3 includes a fixing rod 31, one end of which is fixedly connected to a first sleeve block 34; a second sleeve block 35 is fixedly connected to the outside of the fixing rod 31, and a positioning block 33 is rotatably connected to the outside of the fixing rod 31. One side of the positioning block 33 overlaps one side of the front cover plate 111; a torsion spring 32 is sleeved on the outside of the fixing rod 31, and the two ends of the torsion spring 32 are respectively installed on one side of the positioning block 33 and one end of the second sleeve block 35.
[0029] The overall effect of this embodiment is that after installing the pump body housing 11, front cover plate 111 and rear cover plate 13 using fixing screws 112, by restoring the deformed torsion spring 32 to its original shape, the positioning block 33 rotates outside the fixing rod 31. The positioning block 33 rotates to fit against one side of the front cover plate 111, thereby providing pressure between the rear cover plate 13, the pump body housing 11 and the front cover plate 111, preventing the rear cover plate 13, the pump body housing 11 and the front cover plate 111 from loosening during operation, and improving the tightness of the discharge pump installation.
[0030] The usage and working principle of this device are as follows: The rear cover plate 13, pump body shell 11, and front cover plate 111 are installed in sequence by fixing screws 112. The deformed torsion spring 32 returns to its original shape, so that the positioning block 33 rotates to fit against one side of the front cover plate 111, thereby providing pressure between the rear cover plate 13, pump body shell 11, and front cover plate 111 to make them fasten. The motor drives the magnetic coupling to rotate, so that the first connecting shaft 19 and the driving gear 110 rotate, driving the driven gear 114 to rotate, rotating the material from one end of the material conveying port 116 to the other end. During the material conveying process, the two ends of the first conveying pipe 23 and the second conveying pipe 24 are respectively connected to the inlet and outlet of the heat transfer oil circulation device, ensuring that the high melting point material inside the pump body shell 11 remains in a liquid state and does not solidify.
[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
