[0003] The graphitization furnace is usually heated by the resistance heating principle. Resistor material is filled in the graphitization furnace, and the resistor material is energized. The resistor material generates heat and heats the target material in the graphitization furnace. Since the characteristic of the resistor material is that the resistivity decreases with increasing temperature, during the heating process of the graphitization furnace, the temperature of the resistor material continues to rise, and the resistivity of the resistor material gradually decreases, resulting in a gradual increase in the heating power. This causes the power transformer to have a lower load in the initial heating stage and a higher load in the later heating stage. Therefore, a high-power transformer needs to be purchased for power supply, and the power utilization rate of the transformer is not high in the initial heating stage, which increases the production cost.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] In order to solve the technical problem that the transformer supplying power to the graphitization furnace has a low load in the initial stage of heating and a high load in the later stage of heating, so it is necessary to purchase a high-power transformer for power supply, and the power utilization rate of the transformer is not high in the initial stage of heating, which increases the production cost, the present invention provides a track-movable constant-power power supply continuous graphitization system and an operation method, which can make the power demand in the heating process of the graphitization furnace more stable, improve the power utilization rate of the transformer, and reduce the production cost.

[0019] It should be noted that the track-movable constant-power-supply continuous graphitization system and operation method described in the present invention are used for but not limited to graphitization systems, etc. For the convenience of explanation, in the present invention, only the track-movable constant-power-supply continuous graphitization system and operation method applied to the graphitization system are used as an example for explanation, and the principles of applying the track-movable constant-power-supply continuous graphitization system and operation method to other types of equipment are substantially the same as those applied to the graphitization system, which will not be described one by one here.

[0020] See also Figure 1 , Figure 1Schematic diagram of the structure of a track-movable constant-power-powered continuous graphitization system in one embodiment of the present invention. The track-movable constant-power-powered continuous graphitization system includes a circulating conveying mechanism 1, a power receiving mechanism 2 and a power transmission mechanism 3.

[0021] The circulating conveying mechanism 1 includes a circular track 11 and a plurality of moving carts 12, each of the moving carts 12 can move along the circular track 11, each of the moving carts 12 is installed with a graphitization furnace 4, and each of the graphitization furnaces 4 is provided with a temperature sensor; in this embodiment, two adjacent moving carts 12 are connected by a retractable buffer, and the buffer is hinged to the moving cart, and each moving cart 12 can have its own power and brake device, or some of the moving carts can be selected to have their own power and brake device, and the remaining moving carts are not powered.

[0022] The power connection mechanism 2 includes a plurality of clamps 21, each of which is arranged in sequence along the moving direction of the moving trolley 12, and each of which is used to be electrically connected to a corresponding connector 41 of the graphitization furnace 4; The power transmission mechanism 3 includes a transformer 31 , and an output end of the transformer 31 is electrically connected to each of the clamps 21 .

[0023] When in use, each mobile carriage 12 moves synchronously on the circular track 11, thereby driving the graphitization furnace 4 to pass through the loading station A1, the heating station A2, the cooling station A3 and the unloading station A4 in sequence, and each mobile carriage 12 stops once every time it moves a unit length, and the unit length is the distance between the midpoints of two adjacent graphitization furnaces 4; when any graphitization furnace 4 moves to the loading station A1, the graphitization furnace 4 is loaded; the heating station A2 is divided into a plurality of heating zones A21, each heating zone A21 has a preset heating target temperature, and along the moving direction of the mobile carriage 12, the heating target temperature of each heating zone A21 increases in sequence, and each heating zone A21 is equipped with a clamp 21, when any graphitization furnace 4 moves to a certain heating zone A21, the clamp 21 of the heating zone A21 is electrically connected to the joint 41 of the graphitization furnace 4, and the temperature of the graphitization furnace 4 is detected during heating. When the temperature reaches the preset heating target temperature, the connection between the clamp 21 and the joint 41 of the graphitization furnace 4 is disconnected, and a movement request is issued at the same time. When the system detects that other stations meet the movement conditions, each mobile carriage 12 moves synchronously by a unit length, and the graphitization furnace 4 moves to the next heating zone A21, and continues to heat in the next heating zone A21. The power transmission mechanism 3 supplies power to the clamps 21 of all heating zones A21 at the same time; when any graphitization furnace 4 moves to the cooling station A3, the graphitization furnace 4 is cooled; when any graphitization furnace 4 moves to the unloading station A4, the graphitization furnace 4 is unloaded.

[0024] The technical solution provided by the present invention drives each graphitization furnace 4 to pass through each heating zone A21 in sequence through a circulating conveying mechanism 1. The heating target temperature of each heating zone A21 is different. When the graphitization furnace passes through each heating zone A21 in sequence, the temperature gradually increases. The heating power of the heating zone A21 with a high heating target temperature is high, and the heating power of the heating zone A21 with a low heating target temperature is low. However, since the power transmission mechanism 3 supplies power to the clamps 21 of all heating zones A21 at the same time, after the system is stably running, the total heating power can be kept roughly stable, thereby making the power demand in the heating process more stable, improving the power utilization rate of the transformer, and reducing production costs.

[0025] In one embodiment, see Figure 2-Figure 5 The clamp 21 includes a box body 211, two clamping assemblies 212 and an opening drive member 213. The two clamping assemblies 212 are respectively arranged on both sides of the box body 211. The clamping assemblies 212 include a mounting plate 2121, an elastic member 2122 and an electrode plate 2123. The mounting plate 2121 is fixed in the box body 211. The two ends of the elastic member 2122 are respectively fixedly connected to the mounting plate 2121 and the electrode plate 2123. The electrode plate 2123 is used to abut against a joint 41 of the graphitization furnace 4. The opening drive member 213 is used to make the electrode plates 2123 of the two clamping assemblies 212 move away from each other. In this embodiment, a clearance groove 2111 is provided on one end surface of the box body 211 close to the track. The clearance groove 2111 is used to allow the joint 41 to enter the box body 211.

[0026] In one embodiment, see Figure 2-Figure 5 Two guide holes are provided on the mounting plate 2121, and the clamping assembly 212 also includes two guide rods 2124, one end of the two guide rods 2124 is fixed to the pole plate 2123, and the other end of the two guide rods 2124 is slidably inserted into the two guide holes respectively. By setting the guide rods 2124, the stability of the movement process of the pole plate 2123 can be improved.

[0027] In one embodiment, see Figure 2-Figure 5The opening drive member 213 includes an opening motor 2131, a sleeve 2132 and two pull ropes 2133. The output shaft of the opening motor 2131 is coaxially fixedly connected to the sleeve 2132. One end of the two pull ropes 2133 is fixed and wound around the sleeve 2132. The other ends of the two pull ropes 2133 are respectively fixedly connected to the two electrode plates 2123. When in use, when it is necessary to make the electrode plates 2123 and the joints of the graphitization furnace 4 When the two pole plates 2123 are separated from each other, the sleeve 2132 is driven to rotate by opening the motor 2131, and the pull rope 2133 is reeled in, thereby driving the two pole plates 2123 to move away from each other. When the pole plates 2123 need to clamp the joint 41 of the graphitizing furnace 4, the sleeve 2132 is driven to rotate in the opposite direction by opening the motor 2131, and the pull rope 2133 is unreeled. The two pole plates 2123 are moved closer to each other under the action of the elastic member 2122, thereby clamping the joint 41 of the graphitizing furnace 4.

[0028] In one embodiment, see Figure 2-Figure 5 The opening driving member 213 further includes a plurality of guide wheels 2134 , each guide wheel 2134 is rotatably disposed on the box body 211 , and the pull rope 2133 is sequentially wound around each guide wheel 2134 .

[0029] In one embodiment, see Figure 2-Figure 5 The power connection mechanism 2 also includes a translation assembly 22, which includes a fixed seat 221, a translation cylinder 222 and a connecting plate 223. The cylinder body of the translation cylinder 222 is fixed to the fixed seat 221, and the output shaft of the translation cylinder 222 is fixedly connected to the connecting plate 223. The connecting plate 223 is fixedly connected to each of the box bodies 211 via a plurality of connecting rods 224.

[0030] In one embodiment, see Figure 2-Figure 5 The fixing seat 221 is provided with a plurality of limiting holes, and the translation assembly 22 also includes a plurality of limiting rods 225. The limiting rods 225 are slidably inserted into the limiting holes one by one, and the limiting rods 225 are fixedly connected to the connecting plate 223. By setting the limiting rods 225, the stability of the movement of the connecting plate 223 can be improved.

[0031] The working principle of the power connection mechanism 2 is as follows: (1) When it is necessary to connect electricity, the sleeve 2132 is driven to rotate by opening the motor 2131, and the pull rope 2133 is reeled, thereby driving the two electrode plates 2123 to move away from each other, so that the distance between the two electrode plates 2123 is greater than the distance between the two joints 41 of the graphitization furnace 4, and then the connecting plate 223 is driven by the translation cylinder 222 to move in the direction close to the graphitization furnace 4, so that the two electrode plates 2123 move to the outside of the two joints 41 of the corresponding graphitization furnace 4, and then the sleeve 2132 is driven to rotate in the opposite direction by opening the motor 2131, and the pull rope 2133 is unwound, and the two electrode plates 2123 are moved closer to each other under the action of the elastic member 2122, thereby clamping the joints 41 of the graphitization furnace 4, and connecting electricity; (2) When the connection needs to be disconnected, the sleeve 2132 is driven to rotate by opening the motor 2131, and the pull rope 2133 is reeled in, thereby driving the two electrode plates 2123 away from each other, so that the two electrode plates 2123 are separated from the two joints 41 of the graphitization furnace 4, and then the connecting plate 223 is driven by the translation cylinder 222 to move away from the graphitization furnace 4 to achieve power off.

[0032] In one embodiment, see Figure 2-Figure 5 Each of the clamps 21 includes two first connectors 214, the two first connectors 214 are fixed to the box body 211, and the two first connectors 214 are electrically connected to the two electrode plates 2123 via two first wires 215 respectively; The power connection mechanism 2 also includes two second connectors 23, both of which are fixed to the connecting plate 223, and the two second connectors 23 are electrically connected to the corresponding first connectors 214 of each of the clamps 21 via a plurality of second wires 24; the output end of the transformer 31 is electrically connected to the two second connectors 23, specifically, the output end of the transformer 31 is electrically connected to the two second connectors 23 via two third wires 32.

[0033] The present invention also provides an operation method of a track-movable constant-power-supply continuous graphitization system, which is applicable to the track-movable constant-power-supply continuous graphitization system and comprises the following steps: S1, each mobile carriage 12 moves synchronously on the circular track 11, thereby driving the graphitization furnace 4 to pass through the loading station A1, the heating station A2, the cooling station A3 and the unloading station A4 in sequence, and each mobile carriage 12 stops once every time it moves a unit length, and the unit length is the distance between the midpoints of two adjacent graphitization furnaces 4; S2, when any graphitization furnace 4 moves to the charging station A1, the graphitization furnace 4 is charged; S3, the heating station A2 is divided into several heating zones A21, each heating zone A21 has a preset heating target temperature, and along the moving direction of the mobile trolley 12, the heating target temperature of each heating zone A21 increases in sequence, each heating zone A21 is equipped with a clamp 21, when any graphitization furnace 4 moves to a certain heating zone A21, the clamp 21 of the heating zone A21 is electrically connected to the joint 41 of the graphitization furnace 4, and the temperature of the graphitization furnace 4 is detected during heating. When the temperature reaches the preset heating target temperature, the connection between the clamp 21 and the joint 41 of the graphitization furnace 4 is disconnected, and a moving request is issued at the same time. When the system detects that other stations meet the moving conditions, each mobile trolley 12 moves synchronously by a unit length, and the graphitization furnace 4 moves to the next heating zone A21, and continues to heat in the next heating zone A21. The power transmission mechanism 3 supplies power to the clamps 21 of all heating zones A21 at the same time; S4, when any graphitization furnace 4 moves to the cooling station A3, the graphitization furnace 4 is cooled; S5. When any graphitization furnace 4 moves to the unloading station A4, the graphitization furnace 4 is unloaded.

[0034] The technical solution provided by the present invention drives each graphitization furnace 4 to pass through each heating zone A21 in sequence through a circulating conveying mechanism 1. The heating target temperature of each heating zone A21 is different. When the graphitization furnace passes through each heating zone A21 in sequence, the temperature gradually increases. The heating power of the heating zone A21 with a high heating target temperature is high, and the heating power of the heating zone A21 with a low heating target temperature is low. However, since the power transmission mechanism 3 supplies power to the clamps 21 of all heating zones A21 at the same time, after the system is stably running, the total heating power can be kept roughly stable, thereby making the power demand in the heating process more stable, improving the power utilization rate of the transformer, and reducing production costs.
