[0041] Also includes:

[0042] The partition 2 is provided with a plurality of partitions 2, which are sequentially arranged along the height direction of the silo 1. A cooling pipe 3 is installed inside the partition 2. Both ends of the cooling pipe 3 pass through the silo 1 and are rotatably connected to the silo 1. A damping structure is provided between the cooling pipe 3 and the outer wall of the silo 1, so that the cooling pipe 3 will not rotate under the drive of the external force of the two gears. Both ends of the cooling pipe 3 extend to the outside of the first structural box 6 and the second structural box 9 respectively, and are rotatably connected with a rotary sealing joint 29. The two rotary sealing joints 29 are respectively installed on the outer walls of the first structural box 6 and the second structural box 9, one of the rotary sealing joints 29 is connected to the water supply equipment, and the other rotary sealing joint 29 is connected to the water storage tank. The setting of the rotary sealing joint 29 enables the cooling pipe 3 to rotate normally during use;

[0043] The silo 1 stores granular raw materials, which are stored in different areas through the partition 2 to prevent the raw materials entering the silo 1 first and the raw materials entering later from influencing each other due to large temperature differences. Cooling liquid is introduced into the cooling pipe 3 inside the partition 2 through the water supply equipment, and then the raw materials in the top area are cooled through the partition 2.

[0044] The temperature-averaging and anti-clumping mechanism is provided with multiple groups. The temperature-averaging and anti-clumping mechanism is located above the partition 2. The temperature-averaging and anti-clumping mechanism includes a driven disk 4 rotatably connected to the outer wall of one side of the silo 1, a plurality of mixing rods 5 slidably connected to the inside of the driven disk 4, a driving component for driving the driven disk 4 to rotate, and a displacement component for driving the plurality of mixing rods 5 to move. A second structural box 9 is installed on the outer wall of one side of the silo 1; the displacement component includes a first screw rod 10 rotatably connected to the inside of the second structural box 9, a first motor 11 installed on the outer wall of the second structural box 9, and a driving disk 12 fixed to one end of the plurality of mixing rods 5.

The drive assembly includes a second motor 15 mounted on the outer wall of the second structural box 9 and a linkage sleeve 16 slidably sleeved on the outside of the output shaft of the second motor 15. The outside of the output shaft of the second motor 15 is fixedly connected with a key pin, and a key slot is provided inside the linkage sleeve 16, and the key pin is slidably connected to the inside of the key slot; the drive disk 12 is fixedly sleeved on the outside of the linkage sleeve 16, and a through slot is provided inside the movable block 13, and the inner diameter of the through slot is larger than the outer diameter of the linkage sleeve 16;

[0045] During the raw material storage process, the mixing rod 5 is located inside the silo 1 and above the partition 2. By controlling the second motor 15 to drive the linkage sleeve 16 and the drive disc 12 outside its output shaft to rotate, the multiple mixing rods 5 are driven to rotate synchronously in the circumferential direction, turning the raw materials on the top of the partition 2, so that the raw materials at different positions circulate and contact the partition 2, and the lumps in the raw materials are broken up;

[0046] When the raw materials on the top of the partition 2 need to be guided downward, the first motor 11 is controlled to drive the first screw rod 10 to rotate counterclockwise, driving the movable block 13 to move to the right along the outside of the guide rod 14, and the driving disk 12 moves to the right synchronously, thereby driving multiple mixing rods 5 to move to the right along the inside of the driven disk 4 until the left end of the mixing rod 5 is aligned with the left outer wall of the driven disk 4. In this process, the raw materials adhered to the outside of the mixing rod 5 are removed, and space is made for the partition 2 to flip over. After the material guiding is completed and the partition 2 is in a horizontal state again, the first motor 11 is controlled to drive the first screw rod 10 to rotate clockwise, driving the movable block 13 to move to the left along the outside of the guide rod 14, and the driving disk 12 moves to the left synchronously, thereby driving multiple mixing rods 5 to move to the inside of the silo 1, and re-drive multiple mixing rods 5 to rotate circumferentially to flip the raw materials on the top of the partition 2.

[0047] A first structural box 6, which is installed on the outer wall of the other side of the silo 1;

[0048] The material guide mechanism is arranged inside the first structural box 6 and is used to drive the rotation of each partition 2 from bottom to top. The material guide mechanism includes a first gear 17 installed on the outside of the cooling pipe 3, a second screw rod 18 rotatably connected to the inside of the first structural box 6, and a third motor 19 installed on the top of the first structural box 6; the output end of the third motor 19 is fixedly connected to the top end of the second screw rod 18; the external thread of the second screw rod 18 is connected to a first rack 20, which meshes with each first gear 17 in sequence when moving upward. The first gear 17 is a one-way gear, and the first rack 20 slides with the outer wall of the silo 1;

[0049] When it is necessary to discharge materials from the inside of the silo 1, the raw materials in each area of ​​the silo 1 need to be guided downward in sequence. The third motor 19 is controlled to drive the second screw rod 18 to rotate counterclockwise, and the first rack 20 is driven to move upward along the outer wall of the silo 1. When the first rack 20 is engaged with the first gear 17 at the bottom, the cooling pipe 3 is driven to rotate, and the partition 2 is synchronously driven to rotate, and the raw materials on the top of the partition 2 are gradually guided downward. During the entire engagement process of the first rack 20 and the first gear 17, the cooling pipe 3 and the partition 2 are driven to rotate 180° so that the raw materials on the top of the partition 2 can be fully discharged. As the first rack 20 continues to move upward, each partition 2 is driven to flip 180° in turn, so that the raw materials on the top of each partition 2 are discharged downward in sequence until the first rack 20 completely loses engagement with the first gear 17 at the top;

[0050] After the raw material is guided at the top of the partition 2, the third motor 19 is controlled to drive the second screw 18 to rotate clockwise, driving the first rack 20 to move downward, and the first rack 20 also engages with each first gear 17 in turn. However, since the first gear 17 is a one-way gear, the first rack 20 moves upward to drive the first gear 17 to rotate counterclockwise, and the cooling pipe 3 rotates accordingly. The first rack 20 moves downward to drive the first gear 17 to rotate clockwise, and the cooling pipe 3 does not rotate accordingly, and guides the first rack 20 to lose engagement with the bottom first gear 17.

[0051] An auxiliary processing mechanism is provided inside the first structural box 6 and is used to drive each partition 2 to reciprocate within a set angle. The auxiliary processing mechanism includes a fourth motor 21 mounted on the top of the first structural box 6, a reciprocating screw 22 fixedly sleeved on the outside of the output shaft of the fourth motor 21, and a second gear 23 fixedly sleeved on the outside of the cooling pipe 3; the external thread of the reciprocating screw 22 is connected to a linkage frame 24, which is slidably engaged with the inner wall of the first structural box 6. A plurality of second racks 25 are fixedly connected to the outer wall of the linkage frame 24 along its height direction, and the plurality of second gears 23 respectively cooperate with the plurality of second racks 25;

[0052] During the process of the mixing rod 5 turning the raw materials on the top of the partition 2, the reciprocating screw 22 outside its output shaft is driven to rotate by the fourth motor 21, driving the linkage frame 24 to move back and forth up and down along the outside of the reciprocating screw 22, and the linkage frame 24 drives multiple second racks 25 to move back and forth synchronously up and down, and through the action of the multiple second racks 25 meshing with the multiple second gears 23 respectively, the cooling pipe 3 and the partition 2 are driven to rotate back and forth within a range of 20° in both directions, so that the raw materials at the end of the partition 2 can be repeatedly gathered to the middle thereof, so that the raw materials on the top of the partition 2 can be evenly contacted with the partition 2, and then the raw materials on the top of the partition 2 are evenly cooled, and at the same time, the lumps in the raw materials on the top of the partition 2 can be evenly broken up, avoiding the problem that some lumps are difficult to be broken up due to the dead zone on the top of the partition 2. Before the raw materials on the top of the partition 2 are guided downward, the second rack 25 is driven to separate from the second gear 23, so that the partition 2 is restored to a horizontal state.

[0053] Both ends of the partition 2 are equipped with an extended sealing mechanism, which includes a slide 26 provided at the end of the partition 2, a sealing strip 27 slidably connected to the inside of the slide 26, and a plurality of springs 28 fixed to the inner wall of the slide 26. The other end of the spring 28 is fixed to the outer wall of the sealing strip 27.

[0054] During the process of the mixing rod 5 turning over the raw materials on the top of the partition 2, since the partition 2 will rotate back and forth within a range of 20°, a gap will be generated between the partition 2 and the inner wall of the silo 1. Through the elastic action of the spring 28, the sealing strip 27 is always in contact with the inner wall of the silo 1 to prevent the raw materials from leaking downwards during the turning process.

[0055] Working principle: The silo 1 stores granular raw materials, and the granular raw materials are stored in different areas through the partition 2 to prevent the raw materials that enter the silo 1 first and the raw materials that enter later from having large temperature differences and affecting each other. The cooling liquid is introduced into the cooling pipe 3 inside the partition 2 through the water supply equipment, and then the raw materials in the top area are cooled through the partition 2. During the raw material storage process, the mixing rod 5 is located inside the silo 1 and above the partition 2. By controlling the second motor 15 to drive the linkage sleeve 16 and the drive disk 12 outside its output shaft to rotate, the multiple mixing rods 5 are driven to rotate synchronously in the circumferential direction to turn the raw materials on the top of the partition 2. At the same time, The fourth motor 21 drives the reciprocating screw 22 outside its output shaft to rotate, driving the linkage frame 24 to move back and forth up and down along the outside of the reciprocating screw 22, and through the linkage frame 24, drives the multiple second racks 25 to move back and forth synchronously up and down, and through the multiple second racks 25 respectively meshing with the multiple second gears 23, drives the cooling pipe 3 and the partition 2 to rotate back and forth within a range of 20 degrees in both directions, so that the raw materials at the end of the partition 2 can be repeatedly gathered to the middle thereof, so that the raw materials at the top of the partition 2 can be evenly contacted with the partition 2, and then the raw materials at the top of the partition 2 are evenly cooled, and at the same time, the lumps in the raw materials at the top of the partition 2 can be evenly dispersed. The processing avoids the problem that some lumps are difficult to be broken up due to the dead zone on the top of the partition 2. When the raw materials on the top of the partition 2 need to be guided downward, the first motor 11 is controlled to drive the first screw 10 to rotate counterclockwise, driving the movable block 13 to move to the right along the outside of the guide rod 14, and the driving disk 12 moves to the right synchronously, thereby driving multiple mixing rods 5 to move to the right along the inside of the driven disk 4 until the left end of the mixing rod 5 is aligned with the left outer wall of the driven disk 4. In this process, the raw materials adhered to the outside of the mixing rod 5 are removed, and space is made for the flipping of the partition 2. When it is necessary to discharge the materials from the inside of the silo 1, the raw materials in various areas inside the silo 1 need to be It is guided downward in sequence, and the second screw 18 is driven to rotate counterclockwise by controlling the third motor 19 to drive the first rack 20 to move upward along the outer wall of the silo 1. When the first rack 20 is engaged with the first gear 17 at the bottom, the cooling pipe 3 is driven to rotate, and the partition 2 is driven to rotate synchronously, and the raw materials on the top of the partition 2 are gradually guided downward. During the entire engagement process of the first rack 20 and the first gear 17, the cooling pipe 3 and the partition 2 are driven to rotate 180° so that the raw materials on the top of the partition 2 can be fully discharged. As the first rack 20 continues to move upward, each partition 2 is driven to flip 180° in turn, so that the raw materials on the top of each partition 2 are discharged downward in turn.
