Description

Technical Field

[0001] This utility model relates to the field of evaporator equipment technology, specifically a hybrid cylindrical thin-film evaporator. Background Technology

[0002] Thin-film evaporators are highly efficient evaporation devices widely used in chemical, pharmaceutical, and food industries. They work by evenly distributing materials onto a heated wall to form an extremely thin liquid film, increasing the contact area between the material and the heated surface. Simultaneously, the liquid film is continuously renewed using scrapers or centrifugal force, enhancing the heat and mass transfer process and thus achieving rapid evaporation of the material. During the evaporation process, volatile components in the material vaporize into steam under heating, while non-volatile components are concentrated and discharged.

[0003] Existing Chinese patent document CN118512780A discloses a hybrid cylindrical film evaporator, including a separation cylinder, a first main cylinder, a second main cylinder, a third main cylinder, a fourth main cylinder, and a bottom end cap, which are connected sequentially from top to bottom. The inner lining of the fourth main cylinder and the bottom end cap is made of enamel material. This patent optimizes the material of the inner lining of the film evaporator based on the prior art. By replacing the inner lining of the fourth cylinder and the bottom end cap with enamel material, it can enhance corrosion resistance, resist the erosion of various chemical substances, and improve service life. At the same time, the optimized material selection also reduces costs. However, this hybrid cylindrical film evaporator still has shortcomings: its multiple sets of scraper structures have the same and fixed specifications, and the distance between the scraper end face and the cylinder wall cannot be flexibly adjusted. Since different materials to be evaporated have different physical properties, the scraper with the inability to adjust the distance may cause excessive shearing during the scraping process of some materials, affecting the coating thickness and uniformity, and affecting energy utilization.

[0030] Reference Figure 4 and Figure 5 The fixed collar 10 and the fixed collar 29 are symmetrically provided with bolt holes 11 in four directions on their sides, and fixed bolts 12 are inserted inside the bolt holes 11. The rotating shaft 5 is provided with bolt holes 13 on its side that match the number, specifications and positions of the fixed bolts 12, so as to facilitate and secure the fixed collar 10 and the fixed collar 29 on the rotating shaft 5.

[0031] The above scheme is adopted: the rotating motor 4 is installed on the top of the motor frame 3, the motor frame 3 is fixed to the top surface of the cylinder cover 2, the rotating motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 is movably fitted with a fixing collar 10 and a fixing collar 29. The two are securely fitted on the rotating shaft 5 by the fixing bolt 12 in the bolt through hole 11 and the bolt thread hole 13 on the side of the rotating shaft 5. This structure enables the fixing collar 10 and the fixing collar 29 and the structure connected to them on the outside to achieve quick disassembly and assembly, which facilitates quick replacement and maintenance of the structure connected to the outside of the rotating shaft 5.

[0032] Reference Figures 7 to 9 The second connecting strip 16 is telescopically connected to the first connecting strip 14 through the telescopic groove 15. The fixing stud 20 passes through the adjustment groove 22 and the stud hole 19 and is screwed into the fixing nut 21 to fix the degree of telescopic extension of the second connecting strip 16 and the first connecting strip 14. The scale pointer 25 fixed to the top surface of the end of the second connecting strip 16 extends out of the reading groove 23 and cooperates with the scale mark 24 to facilitate accurate control of the degree of telescopic extension of the second connecting strip 16 and the first connecting strip 14.

[0033] The above scheme is adopted: the paint scraper 18 is connected to the fixed collar 10 and fixed collar 29 through the telescopic structure of connecting strip 14, connecting strip 26, telescopic strip 128 and telescopic strip 20, which can flexibly adjust the distance between the end face of the paint scraper 18 and the inner wall of the mixing cylinder 1, adapt to the characteristics of different materials, and avoid excessive shearing of the material during scraping, which affects the evaporation efficiency and material properties. When adjusting the degree of telescopic movement, the connecting strip 26 can telescopically move within the telescopic groove 15 of the connecting strip 14. The fixing stud 20 passes through the adjusting groove 22 and the stud hole 19 and is screwed into the fixing nut 21 to fix the degree of telescopic movement. The scale pointer 25 on the top surface of the end of the connecting strip 26 extends out of the reading groove 23 and cooperates with the scale mark 24 to facilitate accurate control of the amount of telescopic movement.

[0034] Reference Figure 6 The outer side of the fixed collar 29 is connected by telescopic strips 28 and 30 to realize the function of adjusting the distance between the scraper connecting block 27 driving the paint scraper 18 structure and the rotating shaft 5.

[0035] The above scheme is adopted: telescopic strip 1 28 and telescopic strip 2 30, auxiliary connecting strip 1 14 and connecting strip 2 16 connect the paint scraper 18 and the fixing collar 2 29 to improve the vertical stability of the paint scraper 18.

[0036] Reference Figures 5 to 9 There are four sets of paint scrapers 18, all of which are telescopically connected to the first fixed collar 10 and the second fixed collar 29 through the same connection method. Each set of paint scrapers 18 has several sets of material blocking blocks 26 structures evenly fixed on one side. The direction of the material blocking blocks 26 is consistent with the rotation direction of the rotating shaft 5, so as to limit the speed of the flowing material and increase its contact time with the inner wall of the mixing cylinder 1 in layers.

[0037] The above scheme is adopted: as the rotating shaft 5 rotates, the coating scraper 18 evenly scrapes the material onto the inner wall of the mixing cylinder 1 to form an extremely thin liquid film. At the same time, several sets of material blocking blocks 26 on one side of the coating scraper 18 are arranged in the same direction as the rotation direction of the rotating shaft 5, which can limit the speed of the flowing material, perform simple stratification of the material, increase the contact time between the material and the inner wall of the mixing cylinder 1, and enhance the heat and mass transfer effect.

[0038] Reference Figures 1 to 3 The exhaust vent plate 7 has symmetrical steam vents 31 extending through it in four directions. The mixing cylinder 1 has a steam outlet 32 ​​extending through it on one side. The steam outlet 32 ​​is located between the feed vent plate 6 and the exhaust vent plate 7. The top surface of the cylinder cover 2 has a feed inlet 33 extending through it.

[0039] The above scheme is adopted: steam holes 31 are symmetrically opened in four directions on the plane of the exhaust hole circular plate 7. The vaporized steam rises through these steam holes 31 and is finally discharged from the steam outlet 32 ​​located between the feed hole circular plate 6 and the exhaust hole circular plate 7 on one side of the mixing cylinder 1.

[0040] The working principle of this utility model is as follows: When in use, the material enters from the feed port 33 at one end of the top surface of the cylinder cover 2 and falls onto the feed drain circular plate 6. The feed drain circular plate 6 is a circular plate structure with four sets of symmetrical holes. The material flows through these holes into the conical feed cylinder 8 fixed to the bottom surface. The conical feed cylinder 8 is arranged around the rotating shaft 5. The four sets of feed guide tubes 9 symmetrically arranged on the outer side of the conical feed cylinder 8 introduce the material to the bottom of the exhaust drain circular plate 7, realizing the initial dispersion and conveying of the material. This makes the material flowing into the equipment for distribution evaporation evenly dispersed, thereby improving the evaporation efficiency.

[0041] The rotating motor 4 is installed on the top of the motor frame 3, which is fixed to the top surface of the cylinder cover 2. The rotating motor 4 drives the rotating shaft 5 to rotate. The rotating shaft 5 is movably fitted with a fixing ring 10 and a fixing ring 29. The two are securely fitted onto the rotating shaft 5 by the fixing bolt 12 in the bolt through hole 11 and the bolt thread hole 13 on the side of the rotating shaft 5. This structure allows the fixing ring 10 and the fixing ring 29 and the structure connected to them on the outside to achieve quick disassembly and assembly, which facilitates quick replacement and maintenance of the structure connected to the outside of the rotating shaft 5.

[0042] Fixed collar 10 and fixed collar 29 drive the paint scraper 18 connected to them to rotate around the rotating shaft 5. The paint scraper 18 is connected to the fixed collar 10 and fixed collar 29 through telescopic structures such as connecting strip 14, connecting strip 26, telescopic strip 128 and telescopic strip 20. It can flexibly adjust the distance between the end face of the paint scraper 18 and the inner wall of the mixing cylinder 1 to adapt to the characteristics of different materials and avoid excessive shearing of the material during scraping, which affects the evaporation efficiency and material properties. When adjusting the degree of telescopic movement, the connecting strip 26 can telescopically move within the telescopic groove 15 of the connecting strip 14. The fixing stud 20 passes through the adjusting groove 22 and the stud hole 19 and is screwed into the fixing nut 21 to fix the degree of telescopic movement. The scale pointer 25 on the top surface of the end of the connecting strip 26 extends out of the reading groove 23 and cooperates with the scale mark 24 to facilitate accurate control of the amount of telescopic movement.

[0043] As the rotating shaft 5 rotates, the paint scraper 18 evenly scrapes the material onto the inner wall of the mixing cylinder 1, forming an extremely thin liquid film. At the same time, several sets of material blocking blocks 26 on one side of the paint scraper 18 are arranged in the same direction as the rotation of the rotating shaft 5, which can limit the speed of the flowing material, perform simple stratification of the material, increase the contact time between the material and the inner wall of the mixing cylinder 1, and enhance the heat and mass transfer effect. Under the heating action, the volatile components in the material vaporize into steam.

[0044] The exhaust vent plate 7 has symmetrical steam vents 31 extending through it in all four directions. The vaporized steam rises through these steam vents 31 and is eventually discharged from the steam outlet 32 ​​located between the feed vent plate 6 and the exhaust vent plate 7 on one side of the mixing cylinder 1. The non-volatile components are concentrated inside the mixing cylinder 1 and then discharged from the bottom of the equipment, completing the entire evaporation and concentration process.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
