Description

Technical Field

[0001] This invention relates to the field of roasting furnace technology, and in particular to a graphite product roasting furnace that prevents dry burning. Background Technology

[0002] Graphite products typically require high-temperature roasting in a roasting furnace during production to complete the heat treatment process under set temperature conditions. Some existing roasting furnaces require operators to monitor and replenish the material inside the furnace based on its condition. If the material inside the furnace gradually decreases without timely replenishment, the furnace may continue heating, potentially leading to insufficient material or even a lack of material and increasing the risk of dry burning.

[0003] Meanwhile, when manually observing the material condition inside the furnace and replenishing it, the timing of replenishment is easily affected by the operator's experience and observation, making it difficult to continuously replenish in a timely manner based on changes in the material inside the furnace. Therefore, it is necessary to provide a graphite product roasting furnace that can detect changes in the weight of the material inside the furnace and replenish it when the material is insufficient, in order to reduce the possibility of continuous heating under material shortage conditions. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a graphite product roasting furnace that prevents dry burning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A graphite product roasting furnace with anti-dry burning capability includes a support frame, a mounting frame, a furnace body, a mounting platform, a displacement mechanism, and a feeding mechanism. The support frame has a support platform on both sides, and multiple guide rails are vertically and symmetrically arranged on both sides of the support platform. The mounting frame is vertically and slidably installed between the guide rails on both sides. The furnace body is set on the mounting frame. Side mounting plates are vertically arranged on both sides of the mounting frame. The side mounting plates are slidably fitted on the corresponding guide rails, and a weighing sensor is provided at the bottom of the side mounting plate that contacts the support platform. A mounting platform is provided on one side of the support frame, and a displacement mechanism is arranged laterally on the mounting platform. The feeding mechanism slides laterally on the displacement mechanism. A furnace opening is provided at the end of the furnace body near the feeding mechanism, and a cover plate is provided at the end of the feeding mechanism near the furnace body. When the feeding mechanism moves toward the furnace body through the displacement mechanism, the cover plate seals the furnace opening. The weighing sensor is used to detect changes in the weight of the mounting frame and the furnace body, and the feeding mechanism is used to replenish materials into the furnace body when the detected weight is lower than a set value.

[0006] In addition, a preferred structure is that a guide block corresponding to the guide rail is provided on the outer side of the side mounting plate, the guide block is vertically slidably fitted on the guide rail, the weighing sensor is provided at the bottom of the side mounting plate, and the bottom of the weighing sensor is in contact with the corresponding support platform.

[0007] In addition, a preferred structure is that the furnace body is horizontally arranged in the mounting frame, the mounting frame is provided with a stirring assembly, the stirring assembly is configured to cooperate with the furnace body, and the furnace opening is located on the side of the furnace body close to the mounting platform.

[0008] Furthermore, in a preferred configuration, the displacement mechanism includes a guide rail seat laterally disposed on the mounting platform, a sliding seat slidably fitted on the guide rail seat, and a lead screw motor assembly at one end of the guide rail seat, the lead screw motor assembly being used to control the sliding seat to reciprocate laterally along the guide rail seat.

[0009] In addition, a preferred structure is that the feeding mechanism includes a base, which is disposed on a sliding seat. An extrusion tube is horizontally disposed on the top of the base, and a feeding box is connected to the top of the extrusion tube. A discharge tube is connected to the end of the extrusion tube near the furnace body.

[0010] In addition, a preferred structure is that the extrusion tube has a transversely opened extrusion chamber inside, a motor unit is provided at the end of the extrusion tube away from the discharge pipe, and a screw is transversely rotatably provided inside the extrusion chamber; The screw is connected to the output end of the motor unit, and the inside of the feeding box is provided with a feeding chamber, the bottom of which is connected to the extrusion chamber.

[0011] In addition, a preferred structure is that the discharge pipe has an internal discharge chamber that communicates with the extrusion chamber, and a cover plate is provided at one end of the discharge pipe near the furnace body. The cover plate has a discharge port that communicates with the discharge chamber, and the outer diameter of the cover plate is larger than the inner diameter of the furnace opening.

[0012] In addition, in a preferred configuration, the weighing sensor is used to detect changes in the load on the furnace body in real time. When the detected weight is lower than the set value, the motor unit drives the screw to rotate, so that the material in the feeding chamber is transported into the furnace body through the extrusion chamber, the discharge chamber and the discharge port. When the detected weight reaches the set upper limit, the motor unit stops driving the screw.

[0013] The beneficial effects of this invention are as follows: 1. By installing weighing sensors on both sides of the mounting frame, the load generated by the furnace body and the materials inside can be transmitted to the weighing sensors. This allows the changes in the weight of the furnace body to be judged based on the changes in the internal materials, providing a basis for replenishing materials when they are insufficient, and reducing the possibility of dry burning due to continuous heating of the furnace body in the absence of materials.

[0014] 2. At the same time, the displacement mechanism drives the feeding mechanism to move towards the furnace body, so that the cover plate can seal the furnace opening. The motor unit drives the screw to rotate, and the material in the feeding box is transported into the furnace body through the extrusion pipe and the discharge pipe. This realizes the coordination of weighing detection and feeding process, and reduces the need for repeated manual observation and manual feeding. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Reference Figure 1-9 A graphite product roasting furnace with anti-dry burning function includes a support frame 1, a mounting frame 2, a furnace body 3, a mounting platform 4, a displacement mechanism 5, and a feeding mechanism 6.

[0019] Support platforms 11 are provided on both sides of the support frame 1, and multiple guide rails 12 are vertically and symmetrically arranged on both support platforms 11. The mounting frame 2 is vertically installed between the guide rails 12 on both sides. The furnace body 3 is set on the mounting frame 2, so that the furnace body 3 and the mounting frame 2 form an integral support structure.

[0020] The mounting frame 2 has side mounting plates 22 vertically arranged on both sides. The outer side of the side mounting plates 22 is provided with guide blocks 23 corresponding to the guide rails 12. The guide blocks 23 slide vertically on the guide rails 12, so that the mounting frame 2 can move vertically within a small range along the guide rails 12. At the same time, multiple guide rails 12 are used to restrict the mounting frame 2 from lateral displacement.

[0021] A weighing sensor 24 is provided at the bottom of the side mounting plate 22, and the bottom of the weighing sensor 24 contacts the corresponding support platform 11. Thus, the load formed by the mounting frame 2, the furnace body 3, and the materials inside the furnace body 3 can be transmitted to the weighing sensor 24 through the side mounting plate 22, and the weighing sensor 24 obtains the weight change of the furnace body 3 and the materials inside it according to the load change.

[0022] The furnace body 3 is horizontally arranged inside the mounting frame 2. A furnace opening 31 is provided on the side of the furnace body 3 near the mounting platform 4. The furnace body 3 is used to hold the graphite products to be roasted. A stirring assembly 21 is also provided on the mounting frame 2. The stirring assembly 21 is arranged in conjunction with the furnace body 3 to assist the roasting operation of the furnace body 3.

[0023] A mounting platform 4 is provided on one side of the support frame 1. The mounting platform 4 is adjacent to the furnace opening 31 of the furnace body 3. A displacement mechanism 5 is provided laterally on the mounting platform 4.

[0024] The displacement mechanism 5 includes a guide rail seat 53, a sliding seat 52, and a screw motor assembly 51. The guide rail seat 53 is horizontally fixed on the mounting platform 4, and the sliding seat 52 is horizontally slidably fitted on the guide rail seat 53. The screw motor assembly 51 is located at one end of the guide rail seat 53. The screw motor assembly 51 can control the sliding seat 52 to move along the guide rail seat 53 toward or away from the furnace body 3.

[0025] The feeding mechanism 6 is mounted on the sliding seat 52, so that when the sliding seat 52 moves, it can synchronously drive the feeding mechanism 6 to move laterally.

[0026] The feeding mechanism 6 includes an extrusion tube 61, a feeding box 62, a discharge tube 63, and a base 64. The base 64 is fixedly mounted on the sliding seat 52, and the extrusion tube 61 is horizontally mounted on the top of the base 64. An extrusion chamber 611 is horizontally opened inside the extrusion tube 61. A motor unit 612 is mounted at the end of the extrusion tube 61 away from the furnace body 3. A screw 613 is horizontally rotatably mounted inside the extrusion chamber 611, and one end of the screw 613 is connected to the output end of the motor unit 612.

[0027] The feeding box 62 is located at the top of the extrusion tube 61, and the feeding box 62 has a feeding chamber 621 inside. The bottom of the feeding chamber 621 is connected to the extrusion chamber 611. Before feeding, the material to be roasted can be placed in the feeding chamber 621 in advance, and the material can enter the extrusion chamber 611 under its own gravity.

[0028] The end of the extrusion tube 61 near the furnace body 3 is connected to a discharge tube 63. The discharge tube 63 has an outlet chamber 633 that communicates with the extrusion chamber 611. The end of the discharge tube 63 near the furnace body 3 is provided with a cover plate 631. The cover plate 631 has an outlet 632 that communicates with the outlet chamber 633.

[0029] During material replenishment, the screw motor unit 51 drives the sliding seat 52 to move along the guide rail seat 53 towards the furnace body 3. Simultaneously, the sliding seat 52 drives the feeding mechanism 6 to move, causing the discharge pipe 63 to gradually approach the furnace opening 31 until the cover plate 631 abuts against and seals the furnace opening 31. At this time, the discharge port 632 is connected to the interior of the furnace body 3, forming a material replenishment channel between the feeding mechanism 6 and the furnace body 3.

[0030] In this embodiment, during the roasting operation in the furnace body 3, the load changes of the furnace body 3 are continuously obtained through the weighing sensors 24 on both sides. When the material inside the furnace body 3 gradually decreases, causing the detected weight to drop to the set replenishment range, the displacement mechanism 5 drives the feeding mechanism 6 to approach the furnace body 3, and the cover plate 631 seals the furnace opening 31.

[0031] Then the motor unit 612 is started, and the motor unit 612 drives the screw 613 to rotate in the extrusion chamber 611. After the material in the feeding chamber 621 enters the extrusion chamber 611, it passes through the extrusion chamber 611, the discharge chamber 633 and the discharge port 632 in sequence under the push of the screw 613, and finally enters the furnace body 3 through the furnace opening 31, realizing material replenishment without stopping in the state of manual observation.

[0032] As materials continue to enter the furnace body 3, the overall weight of the furnace body 3 increases synchronously, and the weighing sensor 24 continues to detect the load changes. When the weight of the furnace body 3 reaches the set upper limit for feeding, the motor unit 612 stops driving the screw 613, thereby stopping the feeding; the lead screw motor unit 51 then drives the sliding seat 52 and the feeding mechanism 6 away from the furnace body 3, causing the cover plate 631 to separate from the furnace opening 31.

[0033] The weighing sensor 24 directly detects changes in the material inside the furnace body 3, and works in conjunction with the displacement mechanism 5 and the feeding mechanism 6 to automatically replenish the material. This allows for timely replenishment when the material inside the furnace body 3 is insufficient, reducing the possibility of dry burning caused by continued heating of the furnace body 3 when there is too little or no material. At the same time, the screw 613 can continuously convey the replenished material, making the replenishment process more stable. In this invention, by setting weighing sensors 24 on both sides of the mounting frame 2, the load generated by the furnace body 3 and the materials inside it can be transmitted to the weighing sensors 24. This allows the change in the internal materials to be judged based on the weight change of the furnace body 3, providing a basis for replenishing materials when they are insufficient, and reducing the possibility of the furnace body 3 drying out due to continuous heating in a material shortage state.

[0034] At the same time, the displacement mechanism 5 drives the feeding mechanism 6 to move toward the furnace body 3, so that the cover plate 631 can be sealed at the furnace opening 31. The motor unit 612 drives the screw 613 to rotate, and the material in the feeding box 62 is transported into the furnace body 3 through the extrusion pipe 61 and the discharge pipe 63. This realizes the coordination of weighing detection and feeding process, and reduces the need for repeated manual observation and manual feeding.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
