[0035] In the preferred embodiment, the hot air pipe 12 includes two groups, an upper group and an lower group. A scraper ring 13 is sleeved on the hot air pipe 12. Multiple scraper rings 13 at the same horizontal height are connected to form a whole through a main connecting plate 131. A threaded hole 132 is provided in the middle of the main connecting plate 131, and a screw rod 14 is passed through the threaded hole 132.

[0036] In a preferred embodiment, the same end of the upper and lower screw rods 14 passes through the outside of the box body 1, and the two screw rods 14 outside the box body 1 are matched through a gear set 16, and a crank 15 is provided at the end of one of the screw rods 14.

[0037] In this embodiment:

[0038] Box 1 design:

[0039] The material is stainless steel, with the dimensions of 2000mm in length, 1500mm in width and 1800mm in height, to ensure that the internal space is sufficient for drying the organic silicon raw materials. An interface is reserved at the top of the box to connect the spiral feed pipe 2, and a receiving box 17 is installed at the bottom to collect the dried raw materials.

[0040] Spiral feeding tube 2 and spiral feeding blade 3:

[0041] The spiral feed pipe has a diameter of 200 mm and a length of 1200 mm. The top of one end is connected to the feed pipe 4 through a flange to facilitate the continuous input of raw materials. The spiral feed blade 3 is made of wear-resistant material and arranged along the inner wall of the spiral feed pipe to ensure that the raw materials can be continuously and evenly transported downward.

[0042] Layered blanking structure:

[0043] The upper baffle plate 6 is located at a height of about 600mm in the box body, and the plate surface is provided with 8 first feeding holes 7, the hole diameter decreases from φ50mm to φ20mm from top to bottom to adjust the material flow. The movable rod 8 is arranged below the upper baffle plate and can be driven by a motor to move horizontally in the box body. The movable rod is equipped with 10 spaced-apart material-dispensing blocks 9 to ensure uniform distribution of the material.

[0044] Hot air circulation system:

[0045] Two groups of hot air pipes 12 are arranged in the box, each group includes 4 stainless steel pipes with a diameter of 50 mm, which are distributed on both sides of the box. After the air is heated by the electric heating element, it is evenly sprayed out through the air outlet 121 at the bottom of the hot air pipe. A scraper ring 13 is installed above the hot air pipe, which is driven by the screw rod 14 and the gear set 16 and rotates regularly to remove the material attached to the pipe wall and keep the hot air flowing smoothly.

[0046] Control system:

[0047] The motor 22 is installed on the top of the box body and is connected to the rotating block 21 through a transmission shaft. The annular groove 211 on the rotating block engages with the protrusion 192 of the fan-shaped tooth 19. The fan-shaped tooth support rod 20 is fixed to the outer wall of the box body through a pin shaft. The operator can adjust the reciprocating frequency of the movable rod manually or by motor drive through the crank 15 to achieve precise control of the drying process.

[0048] When the above structure is adopted, after the organosilicon raw material enters the spiral feed pipe 2 through the feed pipe 4, it is slowly transported downward under the action of the spiral feeding blade 3. When it reaches the upper baffle plate 6, the raw material gradually falls into the main area of ​​the box through the first discharge hole 7 of variable diameter. The movable rod 8 is driven by the motor to move laterally periodically, and the material block 9 pushes the material to disperse and avoid accumulation. At the same time, the hot air flow generated by the hot air pipe 12 circulates from bottom to top, quickly taking away the moisture in the raw material. The timed rotation of the scraper ring 13 ensures that the hot air flow path is unobstructed and avoids the accumulation of raw materials on the top of the hot air pipe 12. The entire drying process is fast and uniform, and the dried organosilicon raw material finally falls into the receiving box 17 through the second discharge hole 11 on the lower baffle plate 10, completing the drying process.
