[0023] Reference Figure 2 A leak-proof extraction tank structure includes a tank body 1, two stainless steel plates 2, a roller assembly 3 and a wall plate 4. The inner sides of the wall plates 4 on both sides of the tank body 1 are welded with stainless steel plates 2. The three parts are firmly welded to form a sealed tank structure. The wall plate 4 is connected to the outer side of the stainless steel plate 2. When the extract is contained, there is no leakage at all. The roller assembly 3 includes a roller body 31, a magnetic coupling 32 and a driving assembly 33. The roller body 31 is arranged inside the tank body 1, and the two ends of the roller body 31 are respectively connected to the two stainless steel plates. 2 is rotatably connected, the magnetic coupling 32 is adsorbed on one of the stainless steel plates 2, the driving assembly 33 is fixedly connected to the wall panel 4, and the roller body 31 is connected to the driving assembly 33 through the magnetic coupling 32. By adopting this structure, the roller body 31 is completely sealed in the groove, and then the magnetic coupling principle of the magnetic coupling 32 is utilized to realize the transmission of force and torque between the motor shaft and the roller body bearing without direct contact, thereby eliminating the risk of leakage of the extraction liquid from the roller body mounting hole on the stainless steel plate 2 in the prior art.

[0024] Reference Figure 2In an embodiment of the utility model, bearings 311 and bearing mounting seats 312 are provided at both ends of the roller body 31. The two bearing mounting seats 312 are respectively fixedly connected to the inner walls of the two stainless steel plates 2 and maintained at the same height. A mounting hole is provided on the bearing mounting seat 312, and the bearing 311 is fixedly connected in the mounting hole. The bearing 311 is sleeved on the end of the roller body 31, so that the roller body 31 is rotatably connected to the bearing mounting seat 312 through the bearing 311, so that the roller body 31 can be rotatably connected to the inside of the trough body, thereby ensuring the normal rotation of the roller body 31.

[0025] Reference Figure 3 In the embodiment of the utility model, the magnetic coupling 32 includes an inner magnet 321 and an outer magnet 322. A bearing 311 mounting seat is provided with a cavity. The inner magnet 321 is provided in the cavity, so that the inner magnet 321 is provided on the inner side of the stainless steel plate 2, and the inner magnet 321 is connected to one side of the roller body 31. The outer magnet 322 is provided on the outer side of the stainless steel plate 2. The outer magnet 322 is connected to the driving shaft of the driving assembly 33. When the outer magnet 322 rotates under the drive of the driving assembly 33, the inner magnet 321 is still in a stationary state at the beginning due to the friction force and the resistance of the roller body 31. At this time, the outer magnet 322 begins to deviate from the inner magnet 321 by a certain angle. Due to the existence of this angle, the N pole (S pole) of the outer magnet 322 has a pulling effect on the S pole (N pole) of the inner magnet 321, so that the inner magnet 321 has a tendency to rotate with it, thereby rotating the roller body 31. Under the action of the magnetic coupling 32, the driving motor 331 can effectively transmit the torque to the roller body 31 without contact, thereby realizing the driving function of the roller body 31 and avoiding hitting the mounting holes required for the installation of the roller body 31, thereby effectively preventing the leakage of the extract in the extraction tank, reducing the loss of the extract, and reducing the pollution to the environment and the harm to people.

[0026] Reference Figure 4 , Figure 5 In an embodiment of the utility model, the driving assembly 33 includes a driving motor 331 and a motor fixing seat 332. The driving motor 331 is fixed to the motor fixing seat 332 using fixing screws, and the motor fixing seat 332 is fixedly connected to the wall panel 4 using fixing screws. The output shaft of the driving motor 331 is connected to the external magnet 322, so that the kinetic energy of the driving motor 331 can be transmitted to the roller body 31 through the external magnet 322 and the internal magnet 321, thereby driving the roller body 31 to rotate.

[0027] Since the magnetic coupling 32 has a working clearance requirement, and the wall panel 4 of this embodiment is 30 mm thick, which is too thick, an avoidance hole 21 is provided on the wall panel 4, and the external magnet 322 is arranged in the avoidance hole 21. The thickness of the stainless steel plate 2 welded on the inner side of the wall panel 4 is 3 mm, so that there is only a thinner steel plate as a spacer between the inner magnet 321 and the outer magnet 322, so as to ensure the strength of the connection structure of the magnetic coupling 32, and further ensure the normal operation of the overall structure.

[0028] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
