Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of feeding equipment, specifically to a feeding device for continuous graphitization processing. Background Technology
[0002] Graphitization is a general term for the process of converting products into graphite at high temperatures. Petroleum coke is a byproduct of petroleum processing and is a black carbon product. It is crushed, ground, shaped, dried, and finally converted into graphite through high temperature.
[0003] The production of graphite from petroleum coke requires a high temperature of 2800-3000 degrees Celsius. Continuous processing refers to the continuous graphitization process, which requires the feeding and discharging to be carried out simultaneously. However, current feeding devices can only feed and discharge in single batches, which is intermittent processing and has low efficiency. Therefore, a feeding device for continuous graphitization processing is proposed here. Utility Model Content
[0004] The technical problem this invention aims to solve is that current feeding devices can only feed and discharge materials in single batches, which is intermittent processing and has low efficiency. This invention provides a feeding device for continuous graphitization processing that enables simultaneous feeding and discharging, thereby achieving continuous processing and ensuring processing efficiency.
[0005] The technical solution adopted by this utility model to solve the technical problem is: a feeding device for continuous graphitization processing, including a graphite furnace, with material inlets on both sides of the graphite furnace, a conveyor belt inserted inside the graphite furnace, a preheater on one side of the graphite furnace, a section of the conveyor belt inserted inside the preheater, the conveyor belt being a circulating conveying structure, and limiting plates being fixedly connected at equal intervals to the top side wall of the conveyor belt, the limiting plates being a paired structure, with a placement tray between each pair of limiting plates, and petroleum coke billets placed in the placement tray.
[0006] As a preferred technical solution of this utility model, the inner wall of the preheater is detachably embedded with an electric heating tube, and the upper edge of the openings at both ends of the preheater is fixedly connected with a flexible sealing strip, which is a heat-insulating flexible rubber structure and is a stacked structure.
[0007] As a preferred technical solution of this utility model, slots are provided on the inner wall of the limiting plate and near both ends. Insert blocks are fixedly connected to both ends of the placement plate and at positions opposite to the slots. Both the insert blocks and the slots are T-shaped structures, and the insert blocks are inserted into the slots.
[0008] As a preferred technical solution of this utility model, the placement tray is a through rectangular structure, and a support plate is fixedly connected to the middle of the four inner walls of the placement tray. A partition plate is set in the placement tray through the support plate. The four side walls of the partition plate are not in contact with the inner wall of the slot. A material groove is evenly and throughly opened on the partition plate. A support ring is fixedly connected to the material groove near the bottom edge.
[0009] As a preferred technical solution of this utility model, the graphite furnace is provided with a sliding groove at both ends and near the material inlet, and the graphite furnace is slidably connected to a sealing plate through the sliding groove. The sealing plate has a U-shaped structure and is engaged with the conveyor belt through a bottom recess. The conveyor belt has a slot on the side wall between adjacent limiting plates, and the sealing plate is engaged in the slot.
[0010] This utility model has the following advantages: because the conveyor belt passes through the graphite furnace, it can drive the material on it to move synchronously when the conveyor belt is running, thereby discharging the processed material from the graphite furnace and simultaneously feeding new material into the graphite furnace, achieving the effect of simultaneous discharge and feeding, thus achieving the effect of continuous processing, saving the time spent on feeding, and improving processing efficiency.
[0011] A preheater is installed at the feeding end. The preheater can preheat the material to be processed, thereby reducing the time required for the material to heat up and improving processing efficiency. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] Please refer to the following: Figure 1-3This utility model discloses a feeding device for continuous graphitization processing, including a graphite furnace 1. The graphite furnace 1 has a feeding port 2 on both side walls at both ends. A conveyor belt 4 is inserted inside the graphite furnace 1. A preheater 5 is provided on one side of the graphite furnace 1. One section of the conveyor belt 4 is inserted inside the preheater 5. The conveyor belt 4 is a circulating conveying structure. A limiting plate 8 is fixedly connected at equal intervals on the top side wall of the conveyor belt 4. The limiting plate 8 is a paired structure. A placement tray 10 is provided between each pair of limiting plates 8. Petroleum coke billets are placed in the placement tray 10.
[0018] The technical benefits of this solution are as follows: Material is placed on conveyor belt 4, and starting conveyor belt 4 moves the material into graphite furnace 1. Simultaneously, the processed material in graphite furnace 1 is moved out, achieving synchronous feeding and discharging. This avoids prolonged delays in feeding, which would result in longer processing gaps. Longer gaps lead to lower temperatures inside graphite furnace 1, increasing the time and energy consumed in subsequent processing and hindering efficiency. Because conveyor belt 4 is a circulating conveying structure, its size and space requirements can be reduced. Furthermore, conveyor belt 4 has excellent high-temperature resistance, ensuring its stable existence within graphite furnace 1 and preventing high temperatures from affecting its normal operation.
[0019] The inner wall of the preheater 5 is detachably inlaid with an electric heating tube 6. The upper edge of the openings at both ends of the preheater 5 is fixedly connected with a flexible sealing strip 7, which is a heat-insulating flexible rubber structure and is a stacked structure.
[0020] The technical effects of this solution are as follows: the material to be processed will be located in the preheater 5, and the electric heating tube 6 embedded in the preheater 5 can preheat the material, which can shorten the time required for the material to heat up. Moreover, the preheated material can ensure that the internal and external temperatures rise synchronously during the final heating, thereby reducing the temperature difference and making the two quickly uniform, ensuring high quality and high efficiency of high-temperature processing.
[0021] The inner wall of the limiting plate 8 is provided with slots 9 near both ends. The two ends of the placement tray 10 are fixedly connected with inserts 14 at positions opposite to the slots 9. Both the inserts 14 and the slots 9 are T-shaped structures. The inserts 14 are inserted into the slots 9. The placement tray 10 is a through rectangular structure. The middle of the inner walls of the four sides of the placement tray 10 is fixedly connected with a support plate 16. A partition plate 12 is set inside the placement tray 10 through the support plate 16. The four side walls of the partition plate 12 are not in contact with the inner wall of the slot 11. A material groove 13 is evenly opened through the partition plate 12. A support ring 15 is fixedly connected to the bottom edge of the material groove 13.
[0022] The graphite furnace 1 has grooves at both ends and near the material inlet 2, and the graphite furnace 1 is slidably connected to the sealing plate 3 through the grooves. The sealing plate 3 has a U-shaped structure and is locked onto the conveyor belt 4 through the bottom recess. The conveyor belt 4 has a slot 11 on the side wall between adjacent limiting plates 8, and the sealing plate 3 is locked into the slot 11.
[0023] The technical effect of this solution is as follows: the material to be processed is placed into the placement tray 10, and the placement tray 10 is placed between the two corresponding limiting plates 8 to ensure the stability of the material. The support ring 15 fixed in the material trough 13 and the support plate 16 in the slot 11 can ensure that the bottom of the material is suspended, so that the bottom of the material can fully contact the hot air and achieve the effect of full and synchronous heating of the material. The insertion block 14 and the slot 9 can ensure the stability of the slot 11.
[0024] A sealing plate 3 is connected to the side wall of the feed port 2 via a sliding groove, which can block the feed port 2. A high-temperature resistant sealing gasket is fixed on the back of the sealing plate 3 to ensure the tightness of the sealing plate 3 and the feed port 2.
[0025] Specifically, when using this utility model, the placement tray 10 is first placed between the two corresponding limiting plates 8, and then the partition plate 12 is placed in the placement tray 10. Then, the materials are inserted one by one into the material trough 13. The material trough 13 can be opened according to the different shapes of the materials. Then, the conveyor belt 4 is started to send this batch of materials into the preheater 5. During this process, the materials that were originally in the preheater 5 will be sent into the graphite furnace 1, and the materials that were originally processed in the graphite furnace 1 will also be pushed out of the graphite furnace 1 at the same time to achieve the effect of continuous feeding. Then, the staff can place the next batch of materials to be processed through the above steps and wait for the next round of feeding. The materials discharged after processing can be removed from the conveyor belt 4 by mechanical means to avoid the placement tray 10 affecting the bending and conveying of the conveyor belt 4.
