The chain-plate conveying structure of the present invention is located in a completely enclosed pyrolysis and carbonization device, which can completely isolate the air and ensure that no air enters during the operation of the device. In addition, the scraper moves along the surfaces of the upper and lower partitions to ensure that the material will not stick and clog in the device, and no coking will occur inside the device. At the same time, the devices can be connected and stacked in sequence for use, which can extend the carbonization time of the material and further ensure the carbonization effect.

[0018] 2. A carbonization refining device for a new energy refining furnace.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0034] Reference Figures 1-9, a carbonization refining device of a new energy refining furnace, including a box body 1, heaters 4 are respectively installed on both sides of the box body 1, a feed port 2 is opened on the top of the box body 1, and a discharge channel 3 is installed at the bottom. An upper partition 5 and a lower partition 6 are fixedly connected in the box body 1, a pair of main shafts 8 are rotatably connected in the box body 1, a pair of sprockets 9 are respectively installed on the two main shafts 8, and the two sprockets 9 in the same group are connected by a chain 10. A plurality of scrapers 11 are fixedly connected between the two chains 10, the upper partition 5 can contact the bottom of the scraper 11, and the lower partition 6 can contact the top of the scraper 11. A blanking port 7 communicating with the discharge channel 3 is opened on the lower partition 6, and a motor 12 is fixedly connected to the rear end of the box body 1, and the output shaft of the motor 12 is fixedly connected to the end of one of the main shafts 8;

[0035] When in use, after starting the device, the raw materials to be refined are added into the box body 1 from the feed port 2, the output shaft of the motor 12 will drive the main shaft 8 to rotate, the main shaft 8 drives the chain 10 to rotate through two sets of sprockets 9, and then the chain 10 will synchronously drive the scraper 11 to move, the scraper 11 will push the raw materials falling from the feed port 2 along the upper partition 5 to the right, and then the raw materials fall onto the lower partition 6 at the end of the upper partition 5, and then the scraper 11 will push the raw materials falling from the upper partition 5 to the left along the lower partition 6, and finally the raw materials fall from the drop port 7 into the discharge channel 3 for discharge, completing the carbonization process, and the equipment can be connected in sequence for superposition use (such as Figure 6 ), so that the carbonization time of the material can be extended.

[0036] Furthermore, the upper partition 5 is rotatably connected to the central shaft 13 at one end away from the feed port 2. The outer wall of the central shaft 13 is fixedly connected to a plurality of blades 14 distributed in an annular array. Both ends of the blades 14 are provided with downwardly inclined material guide portions 15.

[0037] During use, since the width of the upper partition 5 is smaller than the width of the lower partition 6, when the material falls from the end of the upper partition 5, it will hit the blade 14, and then drive the blade 14 to drive the central axis 13 to rotate. The rotating blade 14 can disperse the raw materials, and the material guide parts 15 at both ends of the blade 14 can also guide the raw materials to both sides and disperse them. In this way, the raw materials falling from the upper partition 5 can be more evenly covered on the entire lower partition 6, so that the raw materials are heated more evenly and the carbonization efficiency is improved.

[0038] Furthermore, a pair of baffles 16 are fixedly connected to the top of the lower partition 6, with the ends extending to the blanking port 7. The two baffles 16 are respectively close to the two ends of the scraper 11;

[0039] When in use, the two baffles 16 can block the raw materials, so that the scraper 11 can push away all the raw materials on the lower partition 6, avoiding the raw materials remaining in the equipment and causing adhesion, blockage and coking.

[0040] Furthermore, the top end of the lower partition 6 away from the feed port 2 is an upwardly curved structure;

[0041] When in use, the raw materials falling from the end of the upper partition 5 can slide along the arc structure to the position where the scraper 11 can contact, thereby preventing the raw materials from remaining in the equipment and causing adhesion, blockage and coking.

[0042] In another embodiment, a feed hopper 17 communicating with the feed port 2 is fixedly connected to the top of the box body 1. The upper portion of the feed hopper 17 is spiral-shaped, and a material control mechanism is installed inside the feed hopper 17 and the discharge channel 3.

[0043] During use, raw materials are added to the entire device through the feed hopper 17. The spiral-shaped feed hopper 17 allows the raw materials to be dispersed as much as possible after entering the feed hopper 17 to avoid concentrated accumulation. In this way, when the raw materials enter the upper partition 5, they can also be dispersed. The feed hopper 17 can be controlled to feed intermittently through the material control mechanism, so that a part of the raw materials can be stored in the feed hopper 17 instead of continuous feeding. In this way, the stored raw materials can isolate the feed hopper 17 and the discharge channel 3 from the outside world respectively, preventing air from entering the interior of the equipment. In this way, an oxygen-deficient environment can be actively created for the equipment, so that the equipment does not need to rely on other devices to create a negative pressure environment.

[0044] Furthermore, the material control mechanism includes a sealing plate 18 and a second motor 19. The sealing plate 18 is mounted on the output shaft of the second motor 19. The sealing plate 18 is rotatably connected to the inside of the feed hopper 17 or the discharge channel 3 via a rotating shaft. The second motor 19 is mounted on the outer wall of the feed hopper 17 or the discharge channel 3.

[0045] During use, when the material accumulates to a certain thickness above the sealing plate 18, the motor 2 19 will start to drive the sealing plate 18 to rotate. At this time, the feed hopper 17 and the discharge channel 3 will be connected to realize feeding and discharging respectively. During the feeding and discharging process, since there is material accumulated above the sealing plate 18, the accumulated material can be used to isolate the outside air.

[0046] Furthermore, a plurality of coverage collection modules 20 distributed at the edge are installed on the upper surface of the sealing plate 18. A thickness collection module 21 located above the sealing plate 18 is fixedly connected to the inner wall of the feed hopper 17. A control module 22 is fixedly connected to the outer wall of the feed hopper 17. The coverage collection module 20 is used to detect the area percentage of the raw material covering the sealing plate 18, and the thickness collection module 21 is used to detect the raw material stacking height in real time.

[0047] It should be noted that the coverage acquisition module 20 can be an infrared photoelectric sensor or other device capable of detecting in real time the area percentage of the raw material covering the sealing plate 18, the thickness acquisition module 21 can be an ultrasonic sensor or other device capable of detecting in real time the height of the raw material stacking, and the control module 2 is an embedded controller (such as STM32 series) with an integrated data fusion algorithm. Therefore, the coverage acquisition module 20, the thickness acquisition module 21 and the control module 22 are not specifically limited here and can be selected according to actual needs;

[0048] When in use, the control module 22 receives the information collected by the coverage acquisition module 20 and the thickness acquisition module 21, and compares the collected coverage area percentage with the preset minimum coverage area threshold and the raw material stacking height with the preset thickness threshold, and controls the working state of the material control mechanism according to the comparison results, thereby realizing the automatic opening and closing of the sealing plate 18.

[0049] In another embodiment, through the cooperation of the coverage acquisition module 20, the thickness acquisition module 21, and the control module 22, the control module 22 receives the information collected by the coverage acquisition module 20 and the thickness acquisition module 21, and compares the collected coverage area percentage with a preset minimum coverage area threshold and the raw material stacking height with a preset thickness threshold. The judgment logic for controlling the working state of the material control mechanism based on the comparison results is as follows:

[0050] If D detected ≥D th And at the same time satisfy C detected ≥C th , the sealing plate 18 rotates to open, otherwise the sealing plate 18 remains closed, wherein, D detected is the raw material stacking height, D th is the preset thickness threshold, C detected is the coverage area percentage, C th The preset minimum coverage area threshold.

[0051] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
