[0027] In this embodiment, the automatic conveyor belt 11 is coated with an anti-stick coating for the pour point depressant, and then the user starts the automatic conveyor belt 11, and the automatic conveyor belt 11 starts to operate. After the desulfurized pour point depressant falls onto the automatic conveyor belt 11, the first motor 3 installed on the slide plate 2 is started. Under the action of the first motor 3, the output end of the first motor 3 rotates to drive the turntable 4 to rotate. Under the action of the first chute 5, the turntable 4 rotates to drive the first chute 5 to rotate, thereby driving the central axis 8 to move. Under the action of the second chute 10, the central axis 8 moves to drive the connecting plate 7 to move on the guide rail 9. The movement of the connecting plate 7 drives the interference plate 6 to move. Under the action of the interference plate 6, the accumulated pour point depressant is flattened, thereby improving the production efficiency of the pour point depressant, avoiding equipment blockage or uneven production of the pour point depressant, and improving the quality of the product. The bracket 1 has a supporting function for the automatic conveyor belt 11.

[0028] Example 2

[0029] like Figure 1-Figure 5As shown, a depressant production box 12 is fastened to one side of the top wall of the automatic conveyor belt 11, a water tank 15 is fastened to one side of the inner wall of the depressant production box 12, a water inlet 13 is connected to one side of the top wall of the water tank 15, a water hole 16 is provided on the bottom side of the inner wall of the water tank 15, two water curtain plates 20 are fastened to the inner wall of the depressant production box 12, a water receiving trough 22 is provided on one side of the inner wall of the depressant production box 12, a water pump 17 is installed on one side of the inner wall of the water receiving trough 22, a water supply pipe 18 is installed on one side of the surface wall of the water pump 17, a bellows 14 is fastened to one side of the surface wall of the depressant production box 12, a fan 19 is installed on one side of the inner wall of the bellows 14, and a filter plate 21 is fastened to the bottom side of the inner wall of the depressant production box 12.

Under the action of the water hole 16, the pour point depressant production water in the water tank 15 flows down to the water curtain plate 20 through the water hole 16. Under the action of the water curtain plate 20, the increase The evaporation area of ​​the depressant production water is increased, and the evaporation of the depressant production water takes away the heat inside the depressant production box 12, thereby reducing the temperature inside the depressant production box 12. Then, the fan 19 is started, and the cooler air inside the depressant production box 12 is blown out by the fan 19 to cool the depressant. Finally, the depressant production water that has not evaporated is received by the water receiving tank 22, and the water pump 17 is started. Under the action of the water delivery pipe 18, the depressant production water is returned to the inside of the water tank 15. By setting a reaction and blending chamber 23, when the depressant moves to the rear side through the automatic conveyor belt 11, it is scraped into the reaction and blending chamber 23 by the glue scraper 27. The staff places oil products in the reaction and blending chamber 23, and drives the drive shaft 24 to rotate by the second motor 26. The drive shaft 24 rotates and drives the surface stirring rod 25 to evenly stir the oil products and the depressant, and finally the oil products and the depressant are discharged through the discharge pipe 28 for collection.
