[0032] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0033] like Figures 1-2 As shown, a dehydration apparatus for processing quinine solvent includes:

[0034] The dehydration tank 1 has an inlet 11 on the upper part of its side wall, an outlet 12 on the bottom, and an air outlet pipe on its side wall.

[0035] Conical heating column 2 is located at the bottom center of dehydration tank 1;

[0036] The stirring device includes:

[0037] Drive mechanism 31, drive mechanism 31 is installed on top of dehydration tank 1;

[0038] A stirring shaft assembly is connected to the drive mechanism 31 via a transmission connection.

[0039] The stirring blade 33 is fixedly installed on the stirring shaft assembly.

[0040] In this embodiment, as Figures 1-2As shown, during use, the detoxifying quinine solvent enters from the feed inlet 11 on the upper side wall of the dehydration tank 1. The stirring device drives the stirring shaft assembly to rotate through the drive mechanism 31, so that the stirring blades 33 continuously stir the solvent inside the dehydration tank 1, enhancing the contact effect between the solvent and the heating surface, and achieving uniform mixing of the materials. The conical heating column 2 is set at the bottom of the dehydration tank 1, which can heat the solvent in the tank over a large area from below and accelerate the evaporation of water. The steam generated during the dehydration process is discharged through the vent pipe set on the side wall of the dehydration tank 1.

[0041] Specifically, such as Figure 1 As shown, the drive mechanism 31 is a motor.

[0042] Specifically, such as Figure 1 As shown, the stirring device also includes a planetary gear transmission mechanism, which is installed on the upper part of the dehydration tank 1. The planetary gear transmission mechanism is connected to the output shaft of the drive mechanism 31, and the stirring shaft assembly is connected to the planetary gear transmission mechanism.

[0043] Specifically, such as Figures 1-2 As shown, the planetary gear transmission mechanism includes:

[0044] Planetary carrier, the planetary carrier is rotatably mounted on the upper part of the dehydration tank 1, and the planetary carrier is provided with radial extension arms;

[0045] External gear ring 41 is fixedly installed on the upper inner wall of dehydration tank 1;

[0046] Sun gear 42 is connected to drive mechanism 31 via transmission.

[0047] A pair of planetary gears 43 are located between the outer gear ring 41 and the sun gear 42. The planetary gears 43 are rotatably connected to the radial extension arm of the planet carrier. The planetary gears 43 simultaneously mesh with the inner wall of the outer gear ring 41 and the outer wall of the sun gear 42.

[0048] Specifically, such as Figure 2 As shown, the stirring shaft assembly includes:

[0049] The central stirring shaft 321 is fixedly connected at its upper end to the center of the sun gear 42.

[0050] A pair of side stirring shafts 322, the upper ends of which are fixedly connected to the corresponding planetary gears 43;

[0051] The spiral stirring shaft 323 is located at the end of the central stirring shaft 321 and has a spiral structure.

[0052] In this embodiment, as Figures 1-2As shown, during operation, the detoxifying quinine solvent enters the dehydration tank 1 through the feed inlet 11. After the drive mechanism 31 is started, the motor output shaft drives the sun gear 42 to rotate. The sun gear 42 simultaneously drives a pair of planetary gears 43 to revolve along the inner wall of the outer gear ring 41, and the planetary gears 43 themselves rotate around their axes. The rotation of the sun gear 42 drives the central stirring shaft 321 to rotate, while the combined motion of the planetary gears 43 drives the side stirring shaft 322 to perform a circular trajectory motion, thereby achieving multi-directional stirring of the solvent in the dehydration tank 1.

[0053] Specifically, such as Figure 1 As shown, the dehydration device for processing quinine solvent also includes an observation window 5, which is installed on the dehydration tank 1.

[0054] Specifically, such as Figure 2 As shown, an electric heating tube is installed inside the conical heating column 2, and the electric heating tube is arranged in a spiral structure along the inner circumference of the conical heating column 2.

[0055] Specifically, such as Figure 1 As shown, the outer wall of the dehydration tank 1 is provided with an annular heat-insulating jacket.

[0056] In this embodiment, as Figures 1-2 As shown, the observation window 5 is installed on the side wall of the dehydration tank 1 to monitor the working status inside the dehydration tank 1. Through the observation window 5, the operator can observe the dehydration status, stirring status, and possible abnormalities of the detoxifying quinine solvent in real time.

[0057] The electric heating tubes inside the conical heating column 2 are arranged in a spiral structure along the circumference of the inside of the conical heating column 2. When the electric heating tubes are powered on, heat is conducted to the dehydration tank 1 through the outer wall of the conical heating column 2. The conical structure causes the heat to diffuse upward from the bottom, forming a temperature gradient and promoting the evaporation process of water in the solvent.

[0058] The annular insulating jacket circumferentially arranged on the outer wall of the dehydration tank 1 serves to insulate against heat and reduce heat loss to the outside. In another embodiment, the outer wall of the dehydration tank 1 may not be insulated; instead, heating elements may be installed on the outer wall. By heating the outer wall of the dehydration tank 1, a bidirectional heating mode is formed, resulting in a more uniform temperature distribution inside the tank and facilitating the rapid evaporation of water from the detoxifying solvent. The outer wall heating elements can be heated synchronously with the internal conical heating column 2.

[0059] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
