It includes raw material pretreatment section and continuous rectification section, etc. In the raw material pretreatment section, the raw material needs to be filtered to remove solid impurities.

[0003] In the prior art, the existing technology usually uses filter plate (such as metal sintered filter screen) to remove solid impurities (such as catalyst residue, polymer particles, etc.) in crude amino glycerin to prevent impurities from entering the rectification system, affecting product quality and equipment life. However, this technology has the following problems in actual application:

[0004] Amino glycerin has high viscosity and may contain tiny polymer particles. After long-term operation, impurities are easy to accumulate on the surface of the filter plate, causing the filtration resistance to increase, and even completely block, which requires frequent shutdown for cleaning or replacement of the filter plate. After blocking, it will cause the feed flow to fluctuate, affecting the stable operation of the rectification tower and reducing production efficiency. Therefore, it is urgent to develop a raw material pretreatment technology that is anti-blocking, easy to maintain and suitable for continuous production to improve the overall stability and economy of the amino glycerin rectification process.

However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid obscuring the utility model, some technical features known in the art are not described.

[0026] Unless the direction indicated by the single definition, the directions such as up, down, left, right, front, back, inside and outside involved in this paper are based on the directions such as up, down, left, right, front, back, inside and outside in the drawing shown by the utility model, which is explained here.

[0027] The connection mode can adopt existing modes such as bonding, welding, bolt connection, etc., and the actual needs are accurate.

[0028] Please refer to Figures 1 to 6As shown, a special equipment for the research and development of continuous distillation process of aminoglycerol includes a preheating tank 2, a filter box 1 for processing raw materials is set on the top of the preheating tank 2, a feed inlet 6 is set on the top of the filter box 1, a collection bin 5 is set on the back of the filter box 1, a filter plate 18 is set inside the filter box 1, and a distillation column 3 is an existing device, the working principle of which will not be described in detail here, and is set on one side of the preheating tank 2. A connecting pipe 4 is set between the distillation column 3 and the preheating tank 2.

[0029] A moving assembly for cleaning the filter plate 18 is provided on one side of the filter box 1. The moving assembly includes a mounting plate 12 fixedly installed on one side of the filter box 1. The top of the mounting plate 12 has a mounting groove, and a connecting plate 8 is slidably connected in the mounting groove. A motor 7 is provided on one side of the connecting plate 8. The motor 7 is fixedly installed on one side of the connecting plate 8. The output end of the motor 7 passes through the sliding plate 16 and is connected to a gear 9. A rack 10 is also provided on the top of the mounting plate 12. The gear 9 is meshed with the rack 10. A sliding plate 16 is provided on one side of the gear 9. Limit blocks 17 are provided at both ends of the sliding plate 16. A rotating shaft is provided where the limit block 17 is connected to the gear 9. This way, when the gear 9 rotates, it will not affect the sliding plate 16. A through sliding groove 11 is provided on the outside of the filter box 1. A moving groove 15 is provided on one side of the inside of the filter box 1. The limit block 17 is slidably connected in the sliding groove 11 and the moving groove 15. A scraper 19 is provided at the bottom of the sliding plate 16.

[0030] When the motor 7 is driven, it drives the gear 9 to rotate, so that the gear 9 slides on the top of the rack 10, thereby driving the connecting plate 8 to slide in the mounting groove on the mounting plate 12, and thus driving the entire sliding plate 16 to move.

[0031] A fixing component for limiting the position of the filter plate 18 is provided on one side. The fixing component includes a rotating column 13 provided on one side of the filter box 1. A limiting plate 14 is symmetrically arranged inside the filter box 1. A slot for matching the clamping plate 23 is opened on one side of the limiting plate 14. The filter plate 18 is slidably connected in the limiting plate 14. An installation ring 20 is provided on the outside of the rotating column 13. A top block 21 is provided on one side of the installation ring 20. During rotation, the top block 21 can enter the slot to abut against the top plate 23. A groove corresponding to the position of the top block 21 is opened on the side of the filter plate 18 facing the rotating column 13. A spring 22 is provided in the groove. In its natural state, the spring 22 pushes the clamping plate 23 out of the groove. The end of the spring 22 is connected to the clamping plate 23, and the clamping plate 23 is rotatably connected in the groove.

[0032] When installing the filter plate 18, it is inserted into the limiting plate 14. When the card plate 23 on one side of the filter plate 18 contacts the limiting plate 14, the card is pushed into the groove. Then the filter plate 18 is pushed into the filter box 1. When the card plate 23 contacts the card slot in the filter box 1, the spring 22 returns to its original shape and pushes the card plate 23 out into the card slot to form a limit.

[0033] Working principle: When in use, the raw material is added into the filter box 1 through the feed port 6, and then filtered by the filter plate 18. The raw material is then heated by the preheating tank 2 and enters the distillation column 3 through the connecting pipe 4. Solid impurities remain on the surface of the filter plate 18. Then, the motor 7 is started, and the motor 7 drives the gear 9 to rotate. Since the rack 10 is fixedly installed on the mounting plate 12, the connecting plate 8 drives the motor 7 to move on the mounting plate 12, thereby driving the limit block 17 to drive the sliding plate 16 to move. Thus, the connecting block slides in the sliding groove 11 and the moving groove 15, and the sliding plate 16 drives the scraper 19 to clean the filter plate 18, thereby pushing the impurities into the collection bin 5.

[0034] When the filter plate 18 needs to be replaced, rotate the rotating column 13 so that the top block 21 connected to the outer mounting ring 20 of the rotating column 13 abuts against the clamping plate 23, thereby pushing the clamping plate 23 into the groove, thereby compressing the spring 22, thereby releasing the limit between the filter plate 18 and the filter box 1, and then pulling the filter plate 18 out of the limiting plate 14.

[0035] When the filter plate needs to be replaced, rotate the rotating column so that the top block connected to the outer mounting ring of the rotating column abuts against the clamping plate, thereby pushing the clamping plate into the groove. This compresses the spring, thereby releasing the limit between the filter plate and the filter box, and then pulling the filter plate out from the limit plate.
