At the same time, the positioning bar 211 limits the positioning of the positioning rod 212, thereby improving the stability of the electric control push rod 26 when pushing the refrigeration ring 25 to move.

[0038] At the same time, when the stirring rod 12 rotates, the inclined rail column 35 will be driven to rotate. Since the fixed rod 34 limits the position of the slip ring 32, and the slip ring 32 limits the position of the slip column 33, when the inclined rail column 35 rotates, the inclined groove of the inclined rail column 35 drives the slip column 33 to move up and down, and the slip column 33 drives the slip ring 32 to move up and down along the outer wall of the fixed rod 34.

One extraction tube 412 extends to cavity one 48, and the other extraction tube 412 extends to cavity two 49. The two extraction capsules 411 are respectively plugged into the tops of the two extraction tubes 412. When the sampling tube 42 completes sampling, the two extraction capsules 411 are pressed, and the two extraction capsules 411 respectively extract the sample liquid in cavity one 48 and cavity two 49 through the two extraction tubes 412 and enter the two extraction capsules 411, thereby achieving the purpose of sampling for workers.

[0042] The anti-sedimentation device 5 includes a flipping assembly 51, a cylinder 52 and an arc rod 53. The cylinder 52 is fixed at the bottom of the stirring rod 12, and the arc rod 53 is fixed at the bottom of the cylinder 52. The bottom of the arc rod 53 contacts the bottom of the inner wall of the evaporator body 1. The flipping assembly 51 is arranged on the outside of the cylinder 52. When the stirring rod 12 rotates, the stirring rod 12 drives the cylinder 52 to rotate, and the cylinder 52 drives the arc rod 53 to scrape the raw materials precipitated at the bottom of the inner wall of the evaporator body 1, thereby avoiding the problem of the raw materials sinking to the bottom.

[0043] The flipping assembly 51 includes a pressure ring 511, a hinged rod 512 and a flipping push rod 513. The flipping push rod 513 is hinged at the bottom outer wall of the cylinder 52, and the flipping push rod 513 contacts the outer wall of the blade of the stirring rod 12. The pressure ring 511 is slidably installed under the outer wall of the inclined rail column 35. The hinged rod 512 is hinged between the bottom of the pressure ring 511 and the top of the flipping push rod 513. At the same time, the sliding column 33 pushes the pressure ring 511 to move downward, and the pressure ring 511 pushes the hinged rod 512 to drive the flipping push rod 513 to swing away from the cylinder 52. The flipping push rod 513 pushes the middle part of the evaporator body 1 to the edge of the evaporator body 1, thereby improving the efficiency of uniformly mixing the precipitated raw materials in the raw material liquid.

[0044] When in use, in order to ensure the quality of the product during the evaporation of the raw material liquid, it is often necessary to sample the product. When it is necessary to sample the raw material liquid in the evaporator body 1, the I-shaped rod 43 is rotated, and the I-shaped rod 43 drives the arc-shaped port plate 47 to rotate, and the port of the arc-shaped port plate 47 and the ports corresponding to the cavity 1 48 and the cavity 2 49 are moved to the same vertical line. At the same time, the arc-shaped port plate 47 drives the push plate 45 to rotate, and the push plate 45 moves to the position below the slip ring 32. When the slip ring 32 moves downward, the slip ring 32 will push the push plate 45 to drive the arc-shaped port plate 47 to move downward, and the port of the arc-shaped port plate 47 coincides with the ports corresponding to the cavity 1 48 and the cavity 2 49. At this time, the upper and lower raw material liquids in the evaporator body 1 will flow into cavity 1 48 and cavity 2 49 for collection, thereby achieving the purpose of sampling. When the slip ring 32 pushes the push plate 45 to drive the arc-shaped port plate 47 to move downward, the arc-shaped port plate 47 drives the I-shaped rod 43 to move downward. The staff judges whether the sampling tube 42 has successfully sampled by the moving trajectory of the I-shaped rod 43; when the sampling tube 42 completes the sampling, the two extraction capsules 411 are pressed, and the two extraction capsules 411 respectively extract the sample liquid in cavity 1 48 and cavity 2 49 through the two extraction tubes 412 and enter the two extraction capsules 411, thereby achieving the purpose of sampling by the workers.

[0045] When the stirring rod 12 rotates, the stirring rod 12 drives the cylinder 52 to rotate, and the cylinder 52 drives the arc rod 53 to scrape the raw materials precipitated on the bottom of the inner wall of the evaporator body 1, thereby avoiding the problem of the raw materials sinking to the bottom; at the same time, when the inclined groove of the inclined rail column 35 drives the sliding column 33 to move downward, the sliding column 33 pushes the pressure ring 511 to move downward, and the pressure ring 511 drives the hinged rod 512 to drive the flipping rod 513 to swing away from the cylinder 52, and the flipping rod 513 pushes the middle part of the evaporator body 1 toward the edge of the evaporator body 1, thereby improving the efficiency of uniformly mixing the precipitated raw materials in the raw material liquid.
