Its advantages include high heat transfer efficiency, fast evaporation rate, and short material residence time, making it particularly suitable for the evaporation of heat-sensitive substances.

[0003] During evaporation extraction, the evaporated gas needs to undergo flash evaporation for easy collection. However, low entry steam temperatures affect the effectiveness of flash evaporation, hindering the process. Therefore, a thin-film evaporation fabrication device is provided. The evaporator heats the incoming steam, a fabrication disc inside the evaporator distributes the fabric, and the tubes disperse the steam for easy flash evaporation. Utility Model Content

[0004] The purpose of this invention is to provide a thin-film evaporation fabric device that solves the problem that the low temperature of the evaporating gas makes it difficult to perform flash evaporation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A motor is installed at the top of the evaporator. The motor is connected to a rotating shaft. Connecting rods are installed at the top and bottom of the rotating shaft, and a tube is installed between the upper and lower connecting rods.

[0009] Furthermore: a fabric disc is provided on the rotating shaft, the fabric disc is a circular plate and the circular wall of the fabric disc is serrated.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) In this utility model, the steam that cannot directly enter the flash chamber is dispersed and distributed by the material distribution plate set in the evaporator. The connecting rod connected by the rotating shaft moves, thereby driving the tube between the connecting rods to move. The tube is set in close contact with the evaporator wall, which facilitates the dispersion of the material.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] See Figure 1-3 The present invention provides a thin-film evaporation fabric device, comprising: an evaporator 1, a discharge pipe 2, a first pipe 3, a flash evaporation chamber 4, a pressure gauge 5, a second pipe 6, a control valve 7, a third pipe 8, a desiccant 9, a feed pipe 10, a motor 11, a rotating shaft 12, a connecting rod 13, a pipe body 14, a sealing plate 15, a fabric tray 17, a heating chamber 18, a water inlet pipe 19, a hot water tank 20, a hot water pump 21, a hot water outlet pipe 22, a thermometer 23, a pressure gauge port pipe 24, and a thermometer port pipe 25.

[0026] The evaporator 1 has discharge pipes 2 on the upper and lower sides of its side wall. The discharge pipes 2 are connected to the flash chamber 4 through the first pipe 3. The first pipe 3 is equipped with a pressure gauge 5. The flash chamber 4 has a second pipe 6 at the bottom and a control valve 7 on the second pipe 6. The flash chamber 4 has a third pipe 8 at the top and is connected to the vacuum condenser.

[0027] Both the evaporator 1 and the flash chamber 4 are equipped with desiccant 9 in the upper part.

[0028] A feed pipe 10 is provided on the upper side wall of the evaporator 1. The discharge end of the feed pipe 10 extends into the evaporator 1. A motor 11 is provided on the top of the evaporator 1. The motor 11 is connected to the rotating shaft 12. The rotating shaft 12 extends through the desiccant 9 inside the evaporator 1. Connecting rods 13 are provided at both the top and bottom of the rotating shaft 12. A tube body 14 is provided between the upper and lower connecting rods 13. There are four connecting rods 13 and four tube bodies 14. The tube body 14 is located at one end of the connecting rod 13. The tube body 14 is a hollow tube. Sealing plates 15 are provided at both ends of the tube body 14.

[0029] A fabric disc 17 is provided on the rotating shaft 12 at the upper part of the connecting rod 13. The fabric disc 17 is a circular plate and the circular wall of the fabric disc 17 is serrated.

[0030] A heating chamber 18 is provided on the outer wall of the evaporator 1 at the lower part of the feed pipe 10. The heating chamber 18 is a hollow structure. The heating chamber 18 is connected to the hot water tank 20 through the water inlet pipe 19. The hot water tank 20 is provided with a water inlet. A hot water pump 21 is provided on the water inlet pipe 19. A hot water outlet pipe 22 is provided on the upper wall of the heating chamber 18. A thermometer 23 is provided in the hot water tank 20.

[0031] The upper wall of evaporator 1 is equipped with a pressure gauge port 24 and a temperature gauge port 25.

[0032] Working process: The material extracted in the second distillation of the material is fed into the evaporator 1 through the feed pipe 10. The evaporator 1 is selected as a thin film evaporator. Some of the materials with higher temperature can be directly fed into the flash evaporator 4 through the discharge pipe 2 and the first pipe 3 on the upper side wall of the evaporator 1.

[0033] Materials that do not directly enter the flash evaporator 4 enter the evaporator 1 through the feed pipe 10. A distribution plate 17 is installed on the rotating shaft 12, located below the feed pipe 10 and above the connecting rod 13 within the evaporator 1. The distribution plate 17 is a circular plate with a serrated wall, allowing material to enter the evaporator 1 below it through the serrated area. A motor 11 is installed at the top of the evaporator 1, connected to the rotating shaft 12. The rotating shaft 12 extends through the desiccant 9 and the distribution plate 17 within the evaporator 1. When the rotating shaft 12 moves, the connecting rod 13 moves, thereby driving the tube 14 between the connecting rods 13 to move. The tube 14 is fitted against the wall of the evaporator 1, facilitating the dispersion and distribution of materials. Simultaneously, under the action of the hot water pump 21, the hot water from the hot water tank 20 enters the heating chamber 18 through the inlet pipe 19 to heat the material in the evaporator 1. The heated water is then output through the hot water outlet pipe 22 for recycling. The heating chamber 18 heats the dispersed material, causing a portion of the material to pass between the material distribution plate 17 and the wall of the evaporator 1, and then enter the upper part of the evaporator 1. From there, it enters the flash evaporator 4 through the discharge pipe 2 and the first pipe 3 on the upper side wall of the evaporator 1.

[0034] Material that cannot enter the upper part of evaporator 1 enters flash chamber 4 through discharge pipe 2 and first pipe 3 connected to the bottom of evaporator 1. Evaporator 1 and both flash chambers 4 are equipped with demisters 9 at the top to separate liquid droplets entrained in the gas. Material in the two flash chambers enters the vacuum condenser through third pipe 8 for condensation and collection. The vacuum condenser provides a vacuum in the condenser. Material at the bottom of flash chamber 4 is discharged through second pipe 6. The arrangement of evaporator 1 and two flash chambers 4 facilitates better steam treatment.

[0035] Among them, the pipe body 14 is selected as a PPR pipe, and the two ends of the pipe body 14 are equipped with sealing plates 15. The PPR pipe distributes the steam material in a relatively dispersed manner, which is conducive to heating through the heat conducted by the heating chamber 18 to achieve the evaporation effect.

[0036] The serrated outer wall of the material distribution tray 17 has a gap of 5mm with the inner wall of the evaporator 1. The material distribution tray 17 moves circumferentially with the rotating shaft, which facilitates the even distribution of materials in the evaporator 1.

[0037] The motor 11 uses frequency conversion control to control the speed at 60-80 r / m. A suitable speed is fixed so that the material is evenly distributed in the evaporator 1 through centrifugal force.

[0038] A tube body 14 is provided between the upper and lower connecting rods 13. There are four tube bodies 14. The tube body 14 is a hollow tube. Sealing plates 15 are provided at both ends of the tube body 14 to facilitate the distribution of materials.

[0039] The upper wall of the evaporator 1 is equipped with a pressure gauge port 24 and a temperature gauge port 25. Pressure gauges or temperature gauges can be installed at the corresponding positions on the pressure gauge port 24 and temperature gauge port 25 for easy monitoring.
