[0006] To achieve the above object, the utility model provides the following technical scheme:

[0007] An alkylbenzene sulfonate calcium dehydration and recovery device includes a dehydration tank. An electric heating element is installed on one inner surface of the dehydration tank, and a tank cover is installed at the top of the tank. Through holes are opened on both the left and right sides of the tank cover. Collection mechanisms are provided on both the left and right sides of the dehydration tank.

[0021] Please see Fig. 1 and Fig. 2 In this embodiment of the present invention, a calcium alkylbenzene sulfonate dehydration and recovery device includes a dehydration tank 1, an electric heating tube 22 is installed on one side of the inner surface of the dehydration tank 1, and a tank cover 2 is installed at the upper end of the dehydration tank 1. Through holes 3 are opened on both the left and right sides of the inner surface of the tank cover 2. A collection mechanism 4 is provided on both the left and right sides of the dehydration tank 1. The collection mechanism 4 includes a collection tank 5. A heat exchanger 6 is installed at the upper end of the collection tank 5. A collection pipe 7 is installed at the upper end of the heat exchanger 6. A valve 8 is installed at the upper end of the collection pipe 7. The valve 8 is installed on the upper surface of the tank cover 2 and is directly opposite the through hole 3.

[0022] The heating element 22 is used to heat the calcium alkylbenzene sulfonate inside the dehydration tank 1; and it has a temperature regulation function.

[0023] When the heating temperature is between 64-100℃ (i.e., methanol is above its boiling point), the methanol in the alkylbenzene sulfonate evaporates. At this time, the left valve 8 opens and the right valve 8 closes, and the methanol vapor enters the left collection tank 5. When the heating temperature is above 100℃, the water in the alkylbenzene sulfonate evaporates. At this time, the left valve 8 closes and the right valve 8 opens, and the water vapor enters the right collection tank 5.

[0024] The heat exchanger 6 is used to condense methanol vapor and water vapor into liquid for recycling. The heat exchanger includes a shell and condenser tubes installed in the shell. A refrigerant flows into the condenser tubes to cool the methanol vapor and water vapor.

[0025] exist Figs. 1-4 In the middle section: A first motor 9 is installed on the upper surface of the tank lid 2 between two through holes 3. A stirring rod 10 is installed inside the dehydration tank 1. A lifting mechanism 11 is provided between the first motor 9 and the stirring rod 10. The lifting mechanism 11 includes a support plate 12. A support base 13 is installed on the upper end of the support plate 12. The output end of the first motor 9 is connected to the upper end of the support base 13. A second motor 14 is installed on the rear surface of the support plate 12. A turntable 15 is installed on the output end of the second motor 14. The turntable 15 is located on the front side of the support plate 12. A rotating rod 16 is installed on the outer edge of the front surface of the turntable 15. The surface is provided with a lifting component 17, which includes a connecting rod 18 and two sliding sleeves 20 located on the right side of the connecting rod 18. The rear end of the connecting rod 18 is mounted on the front surface of the support plate 12, and the connecting rod 18 is located on the right side of the turntable 15. A sector-shaped toothed component 19 is rotatably connected to the outside of the connecting rod 18. A rotating rod 16 is slidably connected to the left end of the sector-shaped toothed component 19. The rear end of the sliding sleeve 20 is mounted on the front surface of the support plate 12. A toothed rod 21 is slidably connected inside the two sliding sleeves 20. The right end of the sector-shaped toothed component 19 is meshed with the toothed rod 21. The lower end of the toothed rod 21 is mounted on the upper end of the stirring rod 10.

[0026] The first motor 9 drives the stirring rod 10 to stir the calcium alkylbenzene sulfonate, thereby promoting heating and improving heating efficiency;

[0027] The second motor 14 has a self-locking function, meaning that the motor shaft cannot rotate after the power is cut off;

[0028] When the turntable 15 rotates, the rotating rod 16 will cause the left end of the sector tooth 19 to swing up and down, thereby causing the right end of the sector tooth 19 to swing up and down, which in turn causes the tooth rod 21 to move up and down reciprocally. This allows the stirring rod 10 to move up and down rapidly while rotating horizontally, avoiding the formation of stirring dead zones in certain areas by simply stirring horizontally, thus improving stirring efficiency.

[0029] The working principle of this utility model is as follows: During use, the electric heating tube 22 heats the calcium alkylbenzene sulfonate at a temperature of 64-100℃. The left valve 8 is opened and the right valve 8 is closed, allowing methanol vapor in the calcium alkylbenzene sulfonate to enter the left collection tank 5. After a period of time, the heating temperature of the electric heating tube 22 exceeds 100℃, causing water in the calcium alkylbenzene sulfonate to evaporate. The left valve 8 closes and the right valve 8 opens, allowing water vapor to enter the right collection tank 5, thus completing the dehydration of the calcium alkylbenzene sulfonate. During this process, the first motor 9 drives the stirring rod 10 to rotate and stir the calcium alkylbenzene sulfonate. The second motor 14 drives the rotating rod 16 to rotate via the turntable 15, and drives the toothed rod 21 to move up and down via the sector toothed part 19, thereby driving the stirring rod 10 to move up and down rapidly, thus promoting heating and improving the heating efficiency of the calcium alkylbenzene sulfonate.

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.
