[0002] NMP stands for N-methylpyrrolidone. The production of NMP requires cyclopentanone as a starting material. Since cyclopentanone is a liquid, it needs to be transported through a conveying device during the production of NMP. Therefore, an NMP raw material conveying device is required.

[0003] The NMP raw material conveying devices currently on the market have the following problems in actual use: Traditional NMP raw material conveying devices usually use water pumps to transport liquids. The installation of these water pumps requires the use of various fasteners, which necessitates the use of multiple sealing methods to prevent liquid leakage. At the same time, the water pump needs to be in the liquid, while cyclopentanone is a chemical liquid. When the metal comes into contact with the liquid, a reaction may occur, making it very troublesome to use. Utility Model Content

[0024] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an NMP raw material conveying device.

[0025] like Figure 1-5 As shown, this utility model discloses an NMP raw material conveying device, including a housing 1. An inlet pipe 6 is opened at the top of the housing 1, with external threads on its surface. An internally threaded cap 7 is fitted onto the surface of the inlet pipe 6, and a sealing plug 8 is bonded inside the internally threaded cap 7. The surface of the sealing plug 8 is attached to the inner wall of the inlet pipe 6. An air pump 2 is installed at the top of the housing 1. By installing the air pump 2, when conveying cyclopentanone liquid, air can be pumped into the housing 1, increasing the internal air pressure. This allows the cyclopentanone liquid inside the housing 1 to be conveyed through the outlet pipe 10, thus avoiding direct contact with the cyclopentanone liquid and making it more convenient to use. A fixing plate 3 is welded to the surface of the air pump 2 for fixation. A sealing ring 4 is bonded to the bottom of plate 3, and a sealing groove 5 is opened on the top of the box 1. The sealing ring 4 is located inside the sealing groove 5. A first external threaded rod 11 is welded to the top of the box 1. The first external threaded rod 11 passes through the fixing plate 3. A nut 12 is sleeved on the surface of the first external threaded rod 11. One end of the nut 12 is attached to the top of the fixing plate 3. An outlet pipe 10 is fixedly connected to the surface of the box 1. A rotating plate 9 is welded to the surface of the internal threaded cover 7. By installing the sealing ring 4 and the sealing plug 8, the sealing plug 8 can provide a sealing effect for the inlet pipe 6, while the sealing ring 4 can provide a sealing effect between the air pump 2 and the box 1. Moreover, the sealing structure is located at the top of the device, so the liquid will not leak out, which is very convenient to use.

[0026] Side plates 14 are installed on the side of the enclosure 1. Support rods 15 are fixedly connected to the side of the side plates 14. The support rods 15 are evenly distributed. Support rings 16 are welded to the other end of the support rods 15. By installing the support rods 15, the support rods 15 can provide support for the side plates 14, so that the enclosure 1 can be stably placed on the side plates 14, thereby providing a stable installation effect for the enclosure 1 and strong stability during use.

[0027] A groove 19 is formed on the surface of the side plate 14. A second external threaded rod 20 is welded to the side of the box body 1. The second external threaded rod 20 is located inside the groove 19. A pressing turntable 21 is sleeved on the surface of the second external threaded rod 20. One end of the pressing turntable 21 is attached to the surface of the side plate 14. By installing the second external threaded rod 20, when installing the box body 1, the box body 1 can be placed on the side of the side plate 14, and the second external threaded rod 20 can be placed inside the groove 19. Then the pressing turntable 21 can be rotated. The pressing turntable 21 can increase the friction between the box body 1 and the side plate 14, thereby providing a fixed installation effect between the box body 1 and the side plate 14, which is very convenient during installation.

[0028] A fixing strip 17 is welded inside the support ring 16. A base plate 18 is welded to the other end of the fixing strip 17. A support column 23 is welded to the top of the base plate 18. A support plate 24 is welded to the other end of the support column 23. The top of the support plate 24 is attached to the bottom of the box 1. By installing the base plate 18 and the support plate 24, the contact area between the support ring 16 and the ground can be increased by using the base plate 18. At the same time, the support plate 24 can provide support for the box 1, thereby improving the stability of the device when placed on the ground. The device is more stable during use.

[0029] The bottom of the support ring 16 is bonded with an anti-slip ring 25, the bottom of the base plate 18 is bonded with an anti-slip pad 26, and the support columns 23 are distributed at equal intervals. By installing the anti-slip pad 26 and the anti-slip ring 25, the friction between the device and the ground can be further increased, thereby improving the stability of the device after it is placed on the ground.

[0030] The other end of the second external threaded rod 20 is welded with a baffle 22. The extrusion turntable 21 is located between the baffle 22 and the housing 1. A transparent strip 13 is installed on the surface of the housing 1. By installing the baffle 22, the baffle 22 can provide a limiting effect for the extrusion turntable 21, so that the extrusion turntable 21 will not detach from the second external threaded rod 20, which is very convenient to use.

[0031] The working principle of this NMP raw material conveying device is as follows: When using this device, the housing 1 should first be installed on the side plate 14. The housing 1 can be placed on the side of the side plate 14, with the second external threaded rod 20 positioned inside the slide groove 19. Simultaneously, the bottom of the housing 1 should be flush against the top of the support plate 24. Then, the extrusion turntable 21 can be rotated. The extrusion turntable 21 increases the friction between the housing 1 and the side plate 14, thus providing a secure mounting effect. The device is then placed in a suitable position. Finally... Place the outlet pipe 10 in a suitable position, and the device can then be used. When using the device, an inlet pipe 6 is opened at the top of the housing 1, with external threads on its surface. An internally threaded cap 7 is fitted onto the surface of the inlet pipe 6, and a sealing plug 8 is bonded inside the internally threaded cap 7. The surface of the sealing plug 8 is fitted to the inner wall of the inlet pipe 6. Simultaneously, an air pump 2 is located at the top of the housing 1, and a fixing plate 3 is welded to its surface. A sealing ring 4 is bonded to the bottom of the fixing plate 3, and a sealing groove 5 is opened at the top of the housing 1. The sealing ring 4 is located within the sealing groove. Inside the housing 1, a first external threaded rod 11 is welded to the top. This first external threaded rod 11 passes through the fixing plate 3, and a nut 12 is fitted onto the surface of the first external threaded rod 11. One end of the nut 12 is attached to the top of the fixing plate 3. A liquid outlet pipe 10 is fixedly connected to the surface of the housing 1. When using the device, cyclopentanone liquid can be added into the housing 1 through the liquid inlet pipe 6. Then, the internal threaded cap 7 is installed on the surface of the liquid inlet pipe 6 by rotation. At this time, the sealing plug 8 can provide a sealing effect for the liquid inlet pipe 6, and the sealing ring 4 can be used for the air pump 2 and the housing 1. The system provides a sealing effect. When conveying cyclopentanone liquid, air can be pumped into the tank 1 by the air pump 2 to increase the air pressure inside the tank 1, thereby conveying the cyclopentanone liquid inside the tank 1 through the liquid outlet pipe 10. At this time, the sealing structure of the device is located at the top of the device, and the liquid will not leak out. At the same time, the use of the air pump 2 avoids direct contact with the cyclopentanone liquid, making it more convenient to use. Furthermore, the amount of remaining cyclopentanone liquid inside the tank 1 can be observed through the transparent strip 13, so that cyclopentanone liquid can be added to the tank 1 in a timely manner.
