A frame screen 20 is rotatably connected to the end of support rod 19 away from disc 18 through a shaft. Rectangular sliders 21 are installed on the front and back of frame screen 20. Strip plates 22 are installed on the inner wall of screening box 2. A sealing door 23 is hinged to the top of screening box 2 through a hinge.

[0017] Specifically, the meshing of gears 4 facilitates the two granulation rollers 3 to rotate in opposite directions for extrusion granulation.

[0018] Please see Figure 5 The gear 4 is located inside the motor housing 5. There are two granulation rollers 3 and two gears 4. One end of the granulation roller 3 is fixedly connected to the output end of the drive motor 6. The two granulation rollers 3 abut against each other, and the two gears 4 mesh with each other.

[0019] Specifically, the cleaning brush 15 is designed to facilitate the removal of de-icing agent adhering to the granulation roller 3, thus facilitating granulation; the tension spring 14 is designed to allow the cleaning brush 15 to better fit the granulation roller 3; and the through groove allows the cleaning brush 15 to be easily removed, facilitating its disassembly and replacement.

[0020] Please see Figures 2 to 3 The cleaning brush 15 abuts against the outer surface of the granulation roller 3, one end of the tension spring 14 is fixedly connected to the end of the guide rod 11, and through grooves are provided on both sides of the granulation box 1, with the position of the sealing baffle 10 corresponding to the position of the through groove.

[0021] Specifically, the discharge pipe 24 is designed for easy discharge; the feed hopper 26 is designed for easy feeding; the sealing cap 28 is designed for easy closure of the feed hopper 26, allowing it to granulate in a relatively enclosed space; and the exhaust pipe 27 and pressure relief valve 29 are designed for easy exhaust, preventing excessive pressure inside the granulation box 1 and the screening box 2.

[0022] Please see Figures 1 to 2 The bottom of the screening box 2 is provided with a discharge pipe 24, and the inside of the discharge pipe 24 is provided with a valve 25. The top of the granulation box 1 is provided with a feed funnel 26 and an exhaust pipe 27. The end of the feed funnel 26 is provided with a sealing cap 28, and the inside of the exhaust pipe 27 is provided with a pressure relief valve 29.

[0023] Specifically, the rectangular slider 21 and the rectangular groove on the strip plate 22 work together to guide the frame screen 20 and facilitate the back-and-forth movement of the frame screen 20 to screen the de-icing agent particles.

[0024] Please see Figures 2 to 4 The front of the strip plate 22 is provided with a rectangular groove with the front-back direction as the depth direction and the left-right direction as the length direction. The end of the rectangular slider 21 is located inside the rectangular groove, and the rectangular slider 21 can slide along the length direction of the rectangular groove.

[0025] Specifically, the de-icing agent particles are screened using a frame-shaped screen 20; the sealing door 23 facilitates the removal of the de-icing agent particles remaining in the frame-shaped screen 20.

[0026] Please see Figures 1 to 5 The positions of the frame screen 20 correspond to the positions of the discharge hopper 8 and the sealing door 23, respectively, and the bottom of the granulation box 1 is fixedly connected to the top of the screening box 2.

[0027] In use, open the sealing cap 28 and feed the de-icing agent into the granulation box 1 through the inside of the feed funnel 26. Then, close the feed funnel 26 with the sealing cap 28. The de-icing agent slides down the discharge plate 7 onto the granulation roller 3. The drive motor 6 drives the granulation roller 3 to rotate, and the gears 4 on the granulation roller 3 mesh, causing the two granulation rollers 3 to rotate in opposite directions. The constant temperature heater 9 works to heat and dry the de-icing agent granules, reducing the moisture content in the granules. The exhaust pipe 27 and pressure relief valve 29 facilitate venting and prevent granulation. The pressure inside box 1 and screening box 2 is too high, causing the cleaning brush 15 to come into contact with the granulating roller 3. The guide rod 11 and guide ring 12 work together to guide the brush. The tension spring 14 ensures that the cleaning brush 15 is in close contact with the granulating roller 3. As the granulating roller 3 rotates, the cleaning brush 15 can easily clean the de-icing agent adhering to it. When disassembling and replacing the cleaning brush 15, loosen the bolt 16 to disengage it from the threaded hole, then move the sealing baffle 10 to separate the cleaning brush 15 from the granulating roller 3, and remove the cleaning brush 15 from the through groove. Replace with a new one. After cleaning the brush 15, bring the brush 15 into contact with the granulating roller 3, and bring the sealing baffle 10 into contact with the granulating box 1. Align the threaded hole on the sealing baffle 10 with the threaded hole on the granulating box 1, and screw the bolt 16 into the threaded hole to secure the sealing baffle 10 and the granulating box 1. The formed de-icing agent granules fall onto the discharge funnel 8 and then slide into the inside of the frame screen 20. The servo motor 17 drives the disc 18 to rotate, and the two ends of the support rod 19 are rotatably connected to the disc 18 and the frame screen 20, respectively, so that the support rod 19 and the disc 18 are rotatably connected. The rotating connection revolves around the center of the disc 18, causing the frame screen 20 to move. The rectangular slider 21 moves within the rectangular groove on the strip plate 22, allowing the frame screen 20 to move back and forth to screen the de-icing agent particles. Larger particles are left inside the frame screen 20. The sealing door 23 is opened to easily remove the de-icing agent particles left inside the frame screen 20. Particles of the correct size fall onto the inner bottom wall of the screening box 2. The valve 25 is opened to facilitate discharge through the discharge pipe 24.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
