The end of the plate 454 away from the return pipe 452 is fixedly connected to the inner sticking rod 37, wherein the number of the guide push plate 454 is several, and the end of the guide push plate 454 away from the No. 1 support circular sleeve 451 is provided with a feeding assembly 455, wherein the number of the feeding assembly 455 is several, and a circle is formed in the form of a circumferential array, and a compartment assembly 456 is provided at the center of the circle formed by the feeding assembly 455. By throwing the boiler bottom ash from the top of the slag inlet pipe 33, the boiler bottom ash will enter the slag inlet pipe 33 and the compensation cylinder 34 in sequence. The servo motor 22 is then started, so that the driving gear 23 connected to the output end thereof through the coupling will rotate forwardly, wherein the driving gear 23 will transmit the rotational force to the large sprocket 25 through the chain 24, so the large sprocket 25 will rotate forwardly along with the driving gear 23, and the inner wall of the large sprocket 25 is connected to the return pipe 452, wherein the interior of the return pipe 452 is filled with the low-temperature solution required for heat exchange, so the return pipe 452 will carry the guide push plate 45 fixedly connected to its inner wall 4 rotates forwardly, wherein the other end of the guide push plate 454 is connected to the inner sticking rod 37, so the double-headed rod 36 connected to the other end of the inner sticking rod 37 will lead the blocking fan 35 to rotate forwardly periodically, wherein the blocking fan 35 blocks the tail end of the slag inlet pipe 33, and the number of the blocking fans 35 is two, thereby playing a role in periodic circulation of the boiler bottom ash, making it have a good quality stability during transportation, avoiding local overheating or overcooling, and at the same time playing a role in clear batch management and facilitating the close connection of subsequent processes.

[0047] The low-temperature solution in the reflux pipe 452 will undergo heat exchange with the high-temperature boiler bottom ash.

[0048] The material conveying assembly 455 includes a partition plate 4551, which is fixedly connected to the inner side of the return pipe 452 and the forming plate 453 respectively. The two ends of the partition plate 4551 are symmetrically connected with the longitudinal plates 4552, and the top of the longitudinal plate 4552 is fixedly connected with the guide plate 4553. With the positive rotation of the guide push plate 454, the boiler bottom ash entering the inside of the cylinder formed by the return pipe 452 and the forming plate 453 will be pushed forward to a deep place by the guide push plate 454. The guide push plate 454 is spiral, and the spiral guide push plate allows the material to quickly enter the cylinder in a natural flow state, thereby reducing the retention time of the material when entering the sub-bin and avoiding the accumulation of material at the feed end, preventing the material from being scattered excessively and forming internal dust. When the boiler bottom ash moves to a certain distance, the partition plate 4551 fixedly connected to the inner side of the reflux pipe 452 and the forming plate 453 respectively will rotate forward with the former two, and the top of the partition plate 4551 is fixedly connected to the guide plate 4553 through the longitudinal plate 4552. Therefore, the forward rotation of the guide plate 4553 will push the boiler bottom ash to continue to move forward, and the guide plate 4553 also plays a guiding and conveying role for the boiler bottom ash.

[0049] The bin assembly 456 includes a central roller shaft 4561, both ends of the central roller shaft 4561 are symmetrically connected to end plates 4562, the outer side of the central roller shaft 4561 is fixedly connected to a paging sleeve 4563, the outer side of the paging sleeve 4563 is fixedly connected to an insert plate 4564, the end of the insert plate 4564 away from the paging sleeve 4563 is fixedly connected to a connecting plate 4565, and the two sides of the connecting plate 4565 are symmetrically connected to a first oblique blade 4566 and a second oblique blade 4567, and are accompanied by The positive rotation of the partition plate 4551 will drive the coupling plate 4565 to rotate forward together, wherein the coupling plate 4565 is clamped inside the cylinder. In addition, the entire compartment assembly 456 presents a shape that divides the cylinder into three parts. Therefore, a three-compartment design structure is adopted, which greatly increases the heat exchange area. Therefore, under the same output, the speed of the cylinder with a compartment design is about half of that without a compartment, reducing the wear of the heated surface of the cylinder caused by the high-speed movement of materials at high speeds, as well as the wear of rotating parts at high speeds. The three-compartment structure can support the cylinder and enhance the strength of the cylinder. The internal structure of the cylinder is simple and easy to maintain. The three-compartment structure can evenly distribute the material in the cylinder and reduce the torque of the transmission chain. Under the same size of the cylinder, the motor power of the new Fangyuan three-compartment design is lower and the efficiency is higher.

[0050] In addition, the three-compartment design structure is adopted, which greatly increases the heat exchange area. Therefore, under the same output, the drum speed of the divided compartment design is about 2 / 3 of that of the non-divided compartment design, which reduces the wear of the drum heating surface and the possibility of material breakage caused by the high-speed movement of materials at high speed. The divided compartment design also reduces the height of the material falling after being brought to the top of the drum. The material slides and contacts with the heating surface in the divided compartment space to transfer heat, which greatly reduces the possibility of material breakage.

[0051] The material blocking design is adopted in the cooling section of the cylinder, which increases the stagnation time of the material, reduces the flow speed of the material, increases the contact time between the material and the heat dissipation surface, and prevents the material from being broken due to excessive flow of the material in the cylinder. The material blocking is the material guide plate 4553, and the material lifting is the first oblique blade 4566 and the second oblique blade 4567.

The limit strip 502 is fixedly connected to the outer sleeve 56. 502 is fixedly connected to the top of the inner cavity of the outer sleeve 56, the inner part of the outer sleeve 56 is slidably adapted to the flow limiting slide plate 54, the top of the flow limiting slide plate 54 is fixedly connected to the first magnet 55, the end of the flow limiting slide plate 54 away from the transition plate 52 is squeezed and adapted to the discharge pipe 57, the top of the outer sleeve 56 is fixedly connected to the folding plate 59, the inner side of the folding plate 59 is fixedly connected to the slot plate 50, and the inner side of the slot plate 50 is fixedly connected to the second magnet 501, and finally the boiler bottom ash will be It is transported to the tail end of the reflux pipe 452 and enters the transition plate 52 until it is discharged from the slag discharge pipe 53. When the boiler bottom ash accumulates and blocks the slag discharge pipe 53 and the transition plate 52, the boiler bottom ash will squeeze the current limiting slide plate 54 outward, and then the squeezed current limiting slide plate 54 will carry the leakage pipe 57 and move outward along the inner wall of the outer sleeve 56. When the current limiting slide plate 54 moves to the bottom of the top groove 58 and is limited by the limiting strip 502, the No. 1 magnet 55 fixedly connected to the top of the current limiting slide plate 54 will generate attraction with the No. 2 magnet 501. Finally, under the action of the attraction, the current limiting slide plate 54 will pass through the top groove 58 and be inserted into the slot plate 50. Then the leakage pipe 57 originally blocked by the current limiting slide plate 54 will be connected with the transition plate 52, and finally the subsequent boiler bottom ash will be discharged outward, thereby performing leakage treatment on the boiler bottom ash that is blocked during the discharge process.

[0053] When the present invention is in use: first, the boiler bottom ash is thrown into the cooling mechanism 4 through the top of the slag inlet pipe 33, and then the boiler bottom ash will enter the cooling mechanism 4 through the slag inlet pipe 33 and the compensation cylinder 34 in turn, and then the servo motor 22 is started, so that the driving gear 23 connected to its output end through the coupling will rotate forward, wherein the driving gear 23 will transmit the rotational force to the large sprocket 25 through the chain 24, so the large sprocket 25 will rotate forward together with the driving gear 23, and the inner wall of the large sprocket 25 is connected to the return pipe 452, so the return pipe 452 will rotate forward with the guide push plate 454 fixedly connected to its inner wall, wherein the other end of the guide push plate 454 is connected to the inner sticking rod 37, so the double-headed rod 36 connected to the other end of the inner sticking rod 37 will cause the sealing fan 35 to rotate forward periodically, wherein the sealing fan 35 blocks the tail end of the slag inlet pipe 33, and the number of the sealing fans 35 is two.

[0054] With the forward rotation of the guide pusher plate 454, the boiler bottom ash entering the cylinder body formed by the return pipe 452 and the forming plate 453 will be pushed forward to a deep position by the guide pusher plate 454. When the boiler bottom ash moves to a certain distance, the partition plate 4551 fixedly connected to the inner side of the return pipe 452 and the forming plate 453 respectively will rotate forward with the former two. The top of the partition plate 4551 is fixedly connected to the guide plate 4553 through the longitudinal plate 4552, so the forward rotation of the guide plate 4553 will push the boiler bottom ash to continue to move forward. In addition, with the forward rotation of the partition plate 4551, it will pull the connecting plate 4565 to rotate forward together. However, the two sides of the connecting plate 4565 are symmetrically connected with the first oblique blade 4566 and the second oblique blade 4567.

[0055] Finally, the boiler bottom ash will be transported to the tail end of the reflux pipe 452 and enter the transition plate 52 until it is discharged from the slag discharge pipe 53. When the boiler bottom ash is blocked in the slag discharge pipe 53 and the transition plate 52, the boiler bottom ash will squeeze the current limiting slide plate 54, and then the squeezed current limiting slide plate 54 will carry the leakage pipe 57 and move outward along the outer sleeve 56. When the current limiting slide plate 54 moves to the bottom of the top groove 58 and is limited by the limiting strip 502, the No. 1 magnet 55 fixedly connected to the top of the current limiting slide plate 54 will generate an attraction with the No. 2 magnet 501. Finally, under the action of the attraction, the current limiting slide plate 54 will pass through the top groove 58 and be inserted into the slot plate 50, and then the leakage pipe 57 and the transition plate 52 will be connected to each other, so that the boiler bottom ash will be discharged outward.
