Description

Technical Field

[0001] This invention relates to the field of heat treatment equipment technology, and in particular to a partitioned, segmented, multi-material synergistic heat treatment experimental device. Background Technology

[0002] As a heat treatment experimental device, the tube furnace is mainly used in industries such as metallurgy, glass, heat treatment, lithium battery positive and negative electrode materials, new energy, and abrasives. It is a professional equipment for measuring materials under certain temperature conditions and is widely used in experimental research such as calcination, pyrolysis, and material preparation.

[0003] However, with the increasing complexity of industrial production processes, the requirements for reaction equipment in related experimental research are becoming more stringent. Traditional tubular furnace reactors have relatively simple structures and functions, and can only be used for heat treatment processes involving single materials or pre-mixed multi-material treatment processes. They cannot be used to study more complex multi-material heat treatment processes where one material is pre-treated and then other materials are added. Therefore, it is necessary to improve the structure of existing tubular furnace heat treatment experimental equipment to adapt it to more complex multi-material heat treatment research. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a partitioned, segmented, multi-material synergistic heat treatment experimental device. This device improves the structure of the traditional horizontal tubular furnace reactor, making the device more functional and effectively enhancing the accuracy and scientific rigor of the experimental research process.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A multi-material synergistic heat treatment experimental device with partitioned segmentation, characterized in that it includes a furnace body, furnace tubes, a first material container, and a second material container.

[0007] The furnace body is divided into a first heating zone at the front and a second heating zone at the rear by an internal heat insulation layer. The temperatures of the first heating zone and the second heating zone are controlled by a temperature control device respectively.

[0008] The furnace tube is installed through the furnace body. The interior of the furnace tube is divided into an upper layer and a lower layer by a furnace tube partition. The furnace tube partition is provided with a square through hole, which is located in the first heating zone.

[0009] The first material container is disposed in the upper layer of the furnace tube and can move along the furnace tube, and the second material container is disposed in the lower layer of the furnace tube and can move along the furnace tube. The material in the first material container can be transferred to the second material container through the square through hole.

[0010] Furthermore, the first material container is a square corundum crucible, which is divided into upper and lower parts by a movable pull-out material plate. The upper and lower ends of the square corundum crucible are provided with an upper opening and a lower opening, and the size of the lower opening is less than the size of the square through hole and less than the size of the upper opening.

[0011] Furthermore, it also includes an upper pusher motor, a crucible pusher rod, and a material plate telescopic rod. The square corundum crucible is connected to the upper pusher motor through the crucible pusher rod, and the pull-out material plate is connected to the upper pusher motor through the material plate telescopic rod, which are respectively used to push the square corundum crucible and the pull-out material plate to move.

[0012] Furthermore, the second material container is a cylindrical material bucket with a material inlet at the top. A movable cover is provided at the material inlet, and a cover lever is connected to the movable cover to control the opening and closing of the movable cover.

[0013] Furthermore, it also includes a pusher motor, a connecting rod, and a connecting rod sleeve. The cylindrical material bucket is sequentially driven and connected to the pusher motor through the connecting rod and the connecting rod sleeve to push the cylindrical material bucket to move.

[0014] Furthermore, it also includes a manual rotating shaft, which is connected to the axis of the cylindrical material container and is used to drive the cylindrical material container to rotate.

[0015] Furthermore, a baffle is hinged to the square through hole, and the baffle is connected to a baffle push rod for opening and closing the baffle.

[0016] Furthermore, the two ends of the furnace tube are sealed together by an inlet flange and an outlet flange. An air supply assembly is provided on the inlet flange, and an exhaust assembly is provided on the outlet flange. The air supply assembly and the exhaust assembly are used to supply air to and exhaust air into the furnace tube.

[0017] Furthermore, the gas supply assembly includes an upper inlet valve, an upper flow meter, a lower inlet valve, and a lower flow meter. The upper inlet valve, the upper flow meter, and the upper layer of the furnace tube are connected in sequence, and the lower inlet valve, the lower flow meter, and the lower layer of the furnace tube are connected in sequence.

[0018] Furthermore, the exhaust assembly includes an upper exhaust pipe and a lower exhaust pipe, the upper exhaust pipe being connected to the upper layer of the furnace tube and the lower exhaust pipe being connected to the lower layer of the furnace tube.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. By setting a furnace tube partition, the present invention divides the furnace tube into two independent spaces, allowing the heat treatment process to be carried out simultaneously in the upper and lower layers of the furnace tube without causing relative interference.

[0021] 2. The setting of square through holes, square corundum crucible, and cylindrical material bucket allows the material above to be added to the cylindrical material bucket below, realizing a multi-material collaborative processing process where material A in the cylindrical material bucket is pre-treated and then material B in the square corundum crucible is added.

[0022] 3. The opening and closing design of the material inlet of the cylindrical material tank and the linked manual rotating shaft enable uniform mixing of materials inside the cylindrical material tank, that is, to realize the multi-material mixing process after the pretreatment of material A is completed and material B is added.

[0023] 4. The atmosphere control of the upper and lower layers of the furnace tube is independent of each other, which can ensure the different atmosphere requirements of the materials in the upper and lower layers and meet the different experimental requirements such as pyrolysis, oxidation, and reduction.

[0024] 5. The feeding process of the square corundum crucible and the cylindrical material container is driven by a motor, which can ensure the stability of the experiment and reduce experimental errors caused by human factors. Attached Figure Description

Detailed Implementation

[0029] To enhance understanding of the present invention, we will now describe it in further detail with reference to the accompanying drawings. These embodiments are for illustrative purposes only and do not constitute a limitation on the scope of protection of the present invention.

[0030] Figure 1A specific embodiment of a partitioned segmented multi-material synergistic heat treatment experimental device is shown, including a furnace body 1, a furnace tube 21, a gas supply component, an exhaust component, a square corundum crucible 20, a cylindrical material bucket 24, etc.

[0031] The furnace body 1 is divided into a first heating zone 2 at the front and a second heating zone 4 at the rear by an internal heat insulation layer 3. The temperatures of the first heating zone 2 and the second heating zone 4 are independently controlled by a temperature control device 10 located at the lower end of the furnace body 1. The furnace tube 21 runs through the furnace body 1. The interior of the furnace tube 21 is divided into an upper layer 9 and a lower layer 27 by a furnace tube partition 22. A square through hole 35 is provided on the furnace tube partition 22. The square through hole 35 is located in the center of the first heating zone 2. A baffle 23 is hinged to the square through hole 35. The baffle 23 is connected to a baffle push rod 6. The opening and closing of the baffle 23 is controlled by pulling the baffle push rod 6.

[0032] A square corundum crucible 20 is disposed within the upper layer 9 of the furnace tube and can move along the furnace tube 21. The square corundum crucible 20 is divided into upper and lower parts by a movable pull-out material plate 29. The upper part is a regular square, and the lower part gradually narrows from top to bottom, forming a perforated shape. The upper and lower ends of the square corundum crucible 20 are provided with an upper opening 36 and a lower opening 37, respectively. The size of the lower opening 37 is less than the size of the square through hole 35, which is less than the size of the upper opening 36. The square corundum crucible 20 is connected to an upper pusher motor 14 via a crucible pusher rod 30, and the pull-out material plate 29 is connected to the upper pusher motor 14 via a material plate telescopic rod 31, which are used to push the square corundum crucible 20 and the pull-out material plate 29 to move.

[0033] A cylindrical material hopper 24 is positioned within the lower layer 27 of the furnace tube and can move along the furnace tube 21. A material inlet 32 ​​is located at the upper end of the cylindrical material hopper 24, and a movable cover 34 is located at the material inlet 32. A cover lever 33 is connected to the movable cover 34 to control its opening and closing. The cylindrical material hopper 24 is driven by a connecting rod 25 and a connecting rod sleeve 26, which in turn drives a lower pusher motor 13 to move the cylindrical material hopper 24 back and forth within the lower layer 27 of the furnace tube. A manual rotating shaft 28 is connected to the axis of the cylindrical material hopper 24 and drives the cylindrical material hopper 24 to rotate around the axis, thus mixing the materials within the cylindrical material hopper 24.

[0034] The two ends of the furnace tube 21 are sealed together by an inlet flange 19 and an outlet flange 8. An air supply assembly is installed on the inlet flange 19, and an exhaust assembly is installed on the outlet flange 8. The air supply and exhaust assemblies are used to supply and exhaust air into the furnace tube 21. The air supply assembly includes an upper inlet valve 16, an upper flow meter 17, a lower inlet valve 15, and a lower flow meter 18. The upper inlet valve 16, upper flow meter 17, and upper layer 9 of the furnace tube are connected in sequence, and the lower inlet valve 15, lower flow meter 18, and lower layer 27 of the furnace tube are connected in sequence, respectively controlling the air flow into the upper layer 9 and lower layer 27 of the furnace tube. The exhaust assembly includes an upper exhaust pipe 5 and a lower exhaust pipe 7. The upper exhaust pipe 5 connects to the upper layer 9 of the furnace tube, and the lower exhaust pipe 7 connects to the lower layer 27 of the furnace tube.

[0035] Preferably, the upper pusher motor 14, the lower pusher motor 13, and the manual rotation shaft 28 are all located on one side of the furnace tube inlet flange 19, and the upper pusher motor 14 and the lower pusher motor 13 are supported and connected by the first fixed bracket 11 and the second fixed bracket 12, respectively.

[0036] The specific working process and principle of co-processing two materials using the above embodiments are as follows:

[0037] Before the experiment begins, open the material inlet 32 ​​of the cylindrical material container 24, weigh out the required amount of material A and place it in the cylindrical material container 24, keeping the pull-out material plate 29 in its original position so that the upper and lower parts of the square corundum crucible 20 are separated. Weigh out the required amount of material B and place it into the square corundum crucible 20 through the upper opening 36. Then, set the heating program for the first heating zone 2 and the second heating zone 4 through the temperature control program 10, and use the upper pusher motor 14 and the lower pusher motor 13 to move the square corundum crucible 20 and the cylindrical material container 24 to the left side of the furnace tube 21, further away from the first heating zone 20.

[0038] After the first heating zone 2 and the second heating zone 4 reach the specified temperature, open the lower air inlet valve 15 and adjust the lower flow meter 18 to the specified flow rate. Purge with N2 for 5 minutes. After purging, push the cylindrical material bucket 24 to the constant temperature zone of the first heating zone 2 by the lower pusher motor 13 to perform pyrolysis pretreatment of material A and remove some impurities.

[0039] After the pyrolysis pretreatment of material A is completed, the baffle 23 is opened by pulling the baffle push rod 6, and the upper pusher motor 14 is started at the same time. This drives the crucible push rod 30 and the material plate extension rod 31 of the square corundum crucible 20 to push the square corundum crucible 20 to the position of the square through hole 35. At this time, the square corundum crucible 20 is just stuck in the square through hole 35. Then, the pull-out material plate 29 is pulled to let material B fall from the material port 32 through the lower opening 37 of the square corundum crucible 20 into the cylindrical material bucket 24. Then, the pull-out material plate 29 is returned to its position, the baffle push rod 6 is pushed to close the baffle 23, keeping the upper layer 9 and the lower layer 27 of the furnace tube independent. The material port 32 is closed by the material port sliding rod 33, and the cylindrical material bucket 24 is rotated by shaking the manual rotating shaft 28 to complete the mixing process of the two materials A and B.

[0040] After mixing, the material inlet 32 ​​is opened by the material inlet lever 33, and the cylindrical material bucket 24 is pushed to the constant temperature zone of the second heating zone 4 by the lower pusher motor 13. Air is introduced into the lower layer 27 of the furnace tube through the lower air inlet valve 15 to carry out the synergistic heat treatment process of the mixed materials. The gas generated by the pyrolysis of material A and the synergistic heat treatment process of the mixed materials is discharged through the lower exhaust pipe 7, which facilitates the collection, detection and purification of flue gas.

However, the above content does not limit the scope of protection of the present invention. Any equivalent changes or modifications made in accordance with the spirit and essence of the present invention should fall within the scope of protection of the present invention.
