Description

Technical Field

[0001] The invention relates to the technical field of graphite plate curing devices, and in particular to a graphite plate electric heating curing device. Background Art

[0002] Graphite plates are generally used for chemical electrolysis or battery manufacturing. Graphite plates can provide a reaction surface for electrochemical reactions. Graphite is also corrosion-resistant and can be immersed in chemical liquids for a long time. It can also conduct electricity in a stable state and provide an electron transmission channel for chemical reactions.

[0003] Before manufacturing graphite plates, formed graphite plates are required; the manufacturing process of graphite plates mainly includes five steps in sequence, including:

[0004] 1. Batching and mixing: high-quality graphite powder and adhesive are batched and mixed.

[0005] 2. Compression molding: Use a mold to press the mixture into shape.

[0006] 3. Pre-curing: The molded graphite sheet needs to be pre-cured at low temperature to allow the adhesive to initially solidify.

[0007] 4. High temperature curing: The pre-cured graphite sheet is placed in a curing furnace, usually at a temperature ranging from 1500°C to 3000°C, and heated continuously for several hours. The graphite sheet is finally formed under high temperature curing.

[0008] 5. Cooling and testing: After curing, it needs to be cooled slowly and gradually for several hours to prevent stress from forming inside the board. Finally, quality testing is carried out to ensure that the product meets the predetermined physical and chemical properties.

[0009] In completing the above process, the cooperation of equipment such as molding machines, curing furnaces, cooling mechanisms, etc. is also required to produce high-performance graphite plates.

[0010] In order to increase the number of graphite plates in the curing furnace and improve the curing efficiency of the curing furnace, the graphite plates are placed vertically. In this way, the lower end of the graphite plate needs to bear weight for a long time at high temperature during curing. In order to avoid deformation of the graphite plate, before curing, it is necessary to design a special shell to wrap the graphite plate as a support and then send it into the curing furnace.

[0011] However, if the existing graphite plate curing production line is to complete the step of packing the graphite plate into the shell before high-temperature curing, the production efficiency will be reduced; and the high-temperature curing step of the existing graphite plate curing production line is subject to the functional and structural limitations of the production line equipment. The graphite plates can only be fed in and taken out in batches, and the graphite plates cannot be continuously fed in and taken out online, and the high-temperature curing efficiency of the graphite plates is low. In order to improve the production efficiency of the latest structure of graphite plates, new graphite plate high-temperature heating and curing equipment is needed.

[0012] In summary, it is found that the prior art has at least the following technical problems:

[0013] The existing high-temperature curing furnace for graphite plates cannot be placed vertically, and the graphite plates are continuously fed in and taken out online, and the high-temperature curing step leads to low production efficiency. Summary of the invention

[0027] The graphite plate electric heating curing device provided by the present invention has multiple beneficial effects and greatly improves the curing efficiency and quality of the graphite plate.

[0028] (1) The device uses a high-temperature curing furnace with horizontal rotary feeding and unloading. Compared with the traditional static furnace design, the horizontal rotary feeding and unloading curing furnace uses the horizontal rotation of the roller to make the graphite plate evenly heated during the curing process, avoiding local overheating or uneven cooling, and ensuring the curing quality. In addition, the use of the indexing machine accurately controls the rotation angle of the roller, so that the plate bin on each side of the sealing plate can accurately connect to the inlet or outlet of the high-temperature curing furnace.

[0030] (3) The configuration of the feeding and discharging conveyor lines, in conjunction with the rhythmic feeding unit and the rhythmic removal unit, realizes the automated transportation and processing of graphite plates. The rhythmic feeding unit automatically feeds the graphite plates to be cured into the plate bin, while the rhythmic removal unit is responsible for hooking out the cured graphite plates and sending them to the discharging conveyor line. The entire process does not require manual intervention, preventing workers from approaching the high-temperature curing furnace, greatly improving production efficiency and safety, and reducing operating costs and manual errors.

[0031] (4) The introduction of the temperature control unit and the curing controller further improves the intelligence level of the device. The temperature control unit accurately controls the temperature inside the insulation shell, so that the temperature fluctuation during the curing process is kept within the minimum range, ensuring the consistency and quality of the graphite plate curing. The curing controller monitors and controls the entire curing process in real time through electrical communication connections with the temperature control unit, the indexing machine, the conveyor line, the feeding unit and the removal unit. It can not only record and time the curing time of the graphite plate in each plate bin, but also flexibly adjust the working speed and frequency of the conveyor line, the feeding unit and the removal unit according to the actual position of the plate bin, so as to ensure that each graphite plate can meet the preset curing requirements and realize the online continuous production process of the graphite plate entering and exiting the high-temperature curing furnace.

[0032] In addition, the plate bin inside the drum is designed as a polygonal cover plate, and support columns are set at the corners of each side, making the drum more stable during rotation and the distribution of the plate bin more uniform. This structural design not only simplifies the mechanical structure of the device, but also improves the durability and maintenance convenience of the device. And the polygonal cover plate can be enlarged according to the designed output of the production line, so as to achieve the setting of more bins and improve the curing efficiency of the high-temperature curing furnace.

[0033] In summary, the graphite plate electric heating curing device provided by the present invention realizes efficient, uniform and stable curing treatment of the graphite plate through a series of innovative designs, improves production efficiency and product quality, and reduces operating costs and maintenance difficulties. It has broad application prospects and significant economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS
