Description

Technical Field

[0001] This application relates to the field of cathode carbon block processing equipment technology, and in particular to a fire channel structure for a carbon calcining furnace. Background Technology

[0002] Cathode carbon blocks refer to carbon blocks made from high-quality anthracite, coke, graphite, etc. The processing technology generally includes: raw material crushing → screening → batching → mixing → molding → roasting → cooling → molding processing steps, etc.

[0003] In the roasting stage of charcoal blocks, the main equipment used is the ring roasting furnace. Ring roasting furnaces are generally divided into two types: covered ring roasting furnaces and open ring roasting furnaces. In open ring roasting furnaces, fuel combustion and flue gas flow take place in a closed fire channel, so the furnace is not covered during operation. Open roasting furnaces have the advantages of low fuel consumption, low scrap rate, low filler consumption, high control level, and good product quality.

[0004] The open-type ring roasting furnace is mainly composed of the furnace bottom, fire channel wall, horizontal wall, and material box. When roasting charcoal blocks, a layer of filler material (metallurgical coke) is first laid at the bottom of the material box. Then, the charcoal blocks are moved into the material box, and filler material is filled between the charcoal blocks and the fire channel wall, and between adjacent charcoal blocks. Then, filler material is also covered on top of the charcoal blocks, and then the roasting is carried out.

[0005] Regarding the aforementioned technologies, the inventors believe that the following defects exist: After the charcoal blocks are fired and cooled, before hoisting them, the filler material on top of the charcoal blocks needs to be removed until the hoisting clamps can hold the charcoal blocks. In this process, the filler material may clump together, resulting in greater friction between the charcoal blocks and the filler material. During hoisting, this can easily lead to greater tensile stress on the charcoal blocks, affecting the quality of the finished charcoal blocks. Summary of the Invention

[0006] To improve the quality of finished carbon blocks, this application provides a fire channel structure for a carbon calcining furnace.

[0007] The technical solution for the flue structure of a carbon calcining furnace provided in this application is as follows:

[0008] A carbon calcining furnace flue structure includes a flue wall and a transverse wall, which surround a material box. A receiving plate for receiving carbon blocks and filler is provided at the bottom of the material box. The sidewalls of the receiving plate abut against the flue wall and the transverse wall. Multiple receiving seats are provided on the receiving plate, and carbon blocks are placed on the receiving seats. The receiving seats are slidably mounted on the receiving plate, with the sliding direction of the receiving seats parallel to the depth direction of the material box. A first driving member is provided on the receiving plate for driving the receiving seats to slide. The receiving plate is slidably mounted inside the material box, with the sliding direction of the receiving plate parallel to the depth direction of the material box. The furnace flue structure also includes a second driving member for driving the receiving plate to slide.

[0009] By adopting the above technical solution, the charcoal blocks are placed in front of the material box. First, the filler is laid on the receiving plate, and the receiving seat is submerged in the filler. Then, the charcoal blocks are placed on the receiving seats according to their positions. Finally, the material box is filled with filler, which covers the top of the charcoal blocks. After the charcoal blocks are fired, the first driving component drives the receiving seat to slide. The sliding of the receiving seat causes the charcoal blocks to slide. During the sliding process, the charcoal blocks separate from the bonded filler, which facilitates the subsequent hoisting of the charcoal blocks and reduces the tensile stress inside the charcoal blocks during hoisting. This increases the possibility of improving the molding quality of the charcoal blocks; at the same time, the receiving seat moves the top of the charcoal block out of the filler, making it easier for workers to use clamps to hold the charcoal block and to lift it; also, as the receiving seat moves the charcoal block to push open the filler, it reduces the amount of work that workers have to do to remove the top of the charcoal block from the filler, thus reducing the workload and saving manpower; after the charcoal block is removed, the second driving component drives the receiving plate to slide, and the receiving plate moves the filler toward the opening of the material box, increasing the distance between the top of the filler and the opening of the material box, which facilitates the removal of subsequent filler.

[0010] Optionally, the second driving component includes a first steel wire rope disposed on the bearing surface of the bearing plate, wherein one end of the first steel wire rope away from the bearing plate is connected to the lifting component.

[0011] By adopting the above technical solution, when the receiving plate is moved out, the first wire rope is connected to the overhead crane in the workshop. Then the overhead crane winds up the first wire rope, and the winding of the first wire rope causes the receiving plate to slide, thereby removing the filler material. The operation is simple and convenient.

[0012] Optionally, the first driving component includes a plurality of driving blocks slidably disposed within a receiving plate. Each driving block corresponds to a receiving seat. A driving rod is disposed on the bottom surface of the receiving seat. The driving rod enters the receiving plate and abuts against the top surface of the driving block. The first steel wire rope at one end of the receiving plate enters the receiving plate and is fixedly connected to the driving block. The first steel wire rope slidably passes through the receiving plate, and the other end of the first steel wire rope is fixedly disposed on the receiving plate. The top surface of the driving block is inclined downward toward the direction of the first steel wire rope. The first driving component also includes a second steel wire rope disposed between adjacent driving blocks. The second steel wire rope is in a taut state. The first driving component also includes a return component, which is used to drive the driving block back to its initial position when the first steel wire rope is in a slack state.

[0013] By adopting the above technical solution, after the first wire rope is connected to the gantry crane, the gantry crane winds up the first wire rope. During the winding and sliding process of the first wire rope, the drive block slides. Under the action of the second wire rope, all drive blocks slide. The sliding of the drive blocks causes the drive rod to slide away from the bottom wall of the material box. The sliding of the drive rod causes the receiving seat to slide. The operation is simple and convenient. At the same time, after the drive block slides to the maximum displacement, the position of the drive block is fixed at the above position. Then, the first wire rope is wound up to drive the receiving plate to slide. The operation is simple and convenient. After the lower receiving plate reaches the bottom wall of the material box, the drive block is located close to the sliding first wire rope. The first wire rope is in a slack state. Under the action of the elastic element, the drive block is driven to slide towards the fixed first wire rope, so that the drive block returns to the initial position, which facilitates the subsequent removal of the carbon block from the filler by the receiving seat.

[0014] Optionally, the return component includes a spring disposed within the receiving plate, one end of which is located on the drive block away from the first wire rope, and the other end is located on the receiving plate.

[0015] By adopting the above technical solution, during the lowering process of the receiving plate, under the action of the gravity of the receiving plate, the driving block is located near the sliding first steel wire rope, and the spring is in a stretched state. When the receiving plate is supported by the bottom wall of the material box, under the action of the spring force, the driving block is driven to slide to the initial position, which is simple and convenient to operate. At the same time, the spring has the advantages of simple structure and long service life.

[0016] Optionally, a first connecting pipe is fixedly provided on the receiving plate, the length direction of the first connecting pipe is perpendicular to the length direction of the receiving plate, the first steel wire rope is located inside the first connecting pipe, the first steel wire rope slides inside the first connecting pipe, and the first connecting pipe is filled with cooling water.

[0017] By adopting the above technical solution, during the firing process of the charcoal block, the temperature of the charcoal block, the filler and the fire channel wall is relatively high, close to 1800 degrees Celsius, which affects the physical and chemical properties of the first wire rope. Under the action of the first connecting pipe and cooling water, the maximum temperature of the environment where the first wire rope is located is lower than 100 degrees Celsius, which reduces the possibility of the first wire rope breaking, and thus facilitates the sliding of the receiving seat and the receiving plate.

[0018] Optionally, the first connecting pipe includes an outer pipe and an inner pipe sleeved inside the outer pipe, the first wire rope is located in the inner pipe, and cooling water is contained in the inner pipe and the interlayer between the outer pipe and the inner pipe.

[0019] By adopting the above technical solution, after the cooling water between the outer tube and the inner tube boils, the temperature of the cooling water is about 100 degrees Celsius. At this time, the cooling water heats the inner tube, making the temperature of the cooling water in the inner tube lower than 100 degrees Celsius, which further reduces the working environment temperature of the first wire rope, thereby extending the service life of the wire rope.

[0020] Optionally, the bottom wall of the receiving plate is recessed towards the top wall of the receiving plate to form a receiving groove, the end face of the side wall of the receiving groove is recessed towards the top wall of the receiving plate, and the vertical cross-section of the side wall of the receiving groove is triangular.

[0021] By adopting the above technical solution, when the receiving plate slides towards the opening of the hopper, the powder material of the filling material falls to the bottom of the hopper through the gap between the receiving plate and the side wall of the hopper. This causes the receiving plate to tilt when it is lowered to the bottom wall of the hopper, resulting in the charcoal blocks being in an tilted state during the firing process, making the charcoal blocks prone to deformation. During the lowering process, the triangular side wall of the receiving plate squeezes the side wall of the hopper and the powder material accumulated at the corners of the hopper, causing the powder material to move towards the center of the hopper, thus facilitating the bottom of the receiving plate to be supported by the bottom wall of the hopper.

[0022] Optionally, the receiving groove is provided with multiple partitions, which are parallel to each other and parallel to the width direction of the material box. Each partition has a cleaning plate on its sidewall in the same direction, located on the sidewall facing the adjacent partition. The cleaning plate is hinged to the partition, and the extended surfaces of the cleaning plate and the partition intersect. The hinge axis of the cleaning plate is parallel to the length direction of the partition. A triangular block is provided on the surface of the cleaning plate near the bottom wall of the material box, with one corner of the triangular block abutting against the bottom wall of the material box. The cleaning plate is slidably mounted on the partition, and the sliding direction of the cleaning plate is parallel to the height direction of the partition. A third driving component is provided on the partition for driving the cleaning plate to slide and rotate, scraping impurities from the bottom wall of the material box to the top of the cleaning plate.

[0023] By adopting the above technical solution, after the receiving plate is supported on the bottom wall of the material box, the partition and the triangular block abut against the bottom wall of the material box. At this time, the cleaning plate is driven to slide by the third driving component. Since the cleaning plate is hinged to the partition, the cleaning plate drives the triangular block to slide towards the adjacent partition during the sliding process. During the sliding process, the triangular block scrapes the powder on the bottom wall of the material box, causing the powder to slide onto the cleaning plate. When the triangular block abuts against the adjacent partition, a collection groove is formed between the cleaning plate and the partition. The powder is located in the collection groove. After the receiving plate is placed behind the material box, the staff removes the powder from the collection groove, thereby reducing the amount of powder in the material box and facilitating the horizontal placement of the receiving plate. At the same time, it reduces the process of staff entering the material box to clean the powder, saving manpower.

[0024] Optionally, the third driving component includes a lead screw rotatably mounted on the partition, a mounting block threaded onto the lead screw, a cleaning plate hinged to the mounting block, a spiral spring sleeved on the lead screw, one side of the spiral spring fixedly mounted on the lead screw, and the other side fixedly mounted on the partition, the spiral spring driving the lead screw to have a rotational tendency; a locking block slidably mounted on the partition, a locking block provided at the end of the lead screw, the locking block having a locking groove for locking, after the locking block slides and disengages from the locking block, the lead screw rotates and drives the mounting block to slide, the third driving component further includes a fourth driving component for driving the locking block to slide.

[0025] By adopting the above technical solution, when the cleaning plate is driven to slide, the fourth driving component first drives the locking block to slide. The locking block slides and disengages from the lead screw. At this time, the locking block releases the restriction on the rotation of the lead screw. Under the action of the spiral spring, the lead screw is driven to rotate. The rotation of the lead screw drives the mounting block to slide towards the bottom of the material box. At the same time, the mounting block drives the cleaning plate to rotate, thereby scraping the powder on the bottom wall of the material box. The operation is simple and convenient.

[0026] Optionally, the sliding direction of the latching block is parallel to the sliding direction of the partition. The fourth driving component includes a plug rod slidably disposed on the partition. The sliding direction of the plug rod is parallel to the height direction of the partition. When the receiving plate slides toward the bottom wall of the material box, the plug rod abuts against the bottom wall of the material box, driving the plug rod to slide toward the inside of the partition and abut against the latching block, and causing the latching block to disengage from the latching block.

[0027] By adopting the above technical solution, during the lowering process of the receiving plate, after the insertion rod contacts the bottom of the material box, the insertion rod slides towards the inside of the partition and towards the locking block. When the partition is completely placed on the bottom wall of the material box, the locking block and the lead screw are separated. Then the spiral spring drives the lead screw to rotate, making the operation simple and convenient.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. Place the charcoal blocks in front of the material box. First, lay the filler on the receiving plate and submerge the receiving seat in the filler. Then, place the charcoal blocks on the receiving seats according to their positions. Finally, fill the material box with the filler and cover the top of the charcoal blocks with the filler. After the charcoal blocks are fired, the first driving component drives the receiving seat to slide. The sliding of the receiving seat causes the charcoal blocks to slide. During the sliding process, the charcoal blocks separate from the bonded filler, which facilitates the subsequent hoisting of the charcoal blocks. This reduces the possibility of large tensile stress inside the charcoal blocks during hoisting and improves the molding quality of the charcoal blocks.

[0030] 2. The receiving seat moves the top of the carbon block out of the filler material, making it easier for workers to use clamps to hold the carbon block and for hoisting it. At the same time, as the receiving seat moves the carbon block to push open the filler material, it reduces the amount of work that workers have to do to remove the top of the carbon block from the filler material, thus reducing their workload and saving manpower. After the carbon block is removed, the second driving component drives the receiving plate to slide, and the receiving plate moves the filler material toward the opening of the material box, increasing the distance between the top of the filler material and the opening of the material box, which facilitates the removal of subsequent filler material.

[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0038] This application discloses a fire channel structure for a carbon calcining furnace. (Refer to...) Figure 1 and Figure 2 The carbon calcining furnace flue structure includes a flue wall 1 and a transverse wall 2. In this embodiment, multiple flue holes are opened in the flue wall 1, and refractory bricks are arranged in the flue holes. The flue wall 1 and the transverse wall 2 surround a material box 3, which is rectangular. Further, a receiving plate 4 for receiving carbon blocks and filler is provided at the bottom of the material box 3. The side wall of the receiving plate 4 abuts against the flue wall 1 and the transverse wall 2. Multiple receiving seats 5 are provided on the receiving plate 4. The multiple receiving seats 5 are spaced apart and evenly arranged along the length direction of the receiving plate 4. Carbon blocks are placed on the receiving seats 5. The receiving seats 5 are slidably arranged on the receiving plate 4. The sliding direction of the receiving seats 5 is parallel to the depth direction of the material box 3. A first driving member for driving the receiving seats 5 to slide is provided on the receiving plate 4.

[0039] Before the charcoal blocks are placed into the roasting furnace for firing, filler material is first laid on the receiving plate 4, covering the receiving seat 5. Then, the charcoal blocks are hoisted into the material box 3 and placed on the receiving seat 5. The filler material is then filled into the material box 3 to complete the covering of the charcoal blocks. The charcoal blocks are then fired using natural gas. After the charcoal blocks are fired, the receiving seat 5 is driven to slide by the first driving component. The receiving seat 5 slides away from the bottom of the material box 3, and the receiving seat 5 drives the charcoal blocks to slide towards the opening of the material box 3. During the sliding process, the charcoal blocks push open the filler material covering them. Then, the charcoal blocks are clamped by clamps and removed. In the above process, the charcoal blocks are first separated from the filler material under the action of thrust, and then removed by tension. This reduces the tensile stress in the charcoal blocks, reduces the possibility of damage to the charcoal blocks, and improves the forming quality of the charcoal blocks.

[0040] Reference Figure 1 and Figure 2When the next batch of charcoal blocks is fired in the feed bin 3, the filler material inside the feed bin 3 needs to be removed. At this time, a grab bucket needs to be used to enter the feed bin 3 and grab the filler material. During the operation, there is a possibility that the grab bucket will collide with the fire channel wall 1, and the travel distance of the grab bucket gradually increases, making it difficult to remove the filler material. In order to facilitate the removal of the filler material in the feed bin 3, the receiving plate 4 is slidably set in the feed bin 3. The sliding direction of the receiving plate 4 is parallel to the depth direction of the feed bin 3. The furnace fire channel structure also includes a second driving component for driving the receiving plate 4 to slide. The system includes a first steel wire rope 6 installed on the receiving surface of the receiving plate 4. The end of the first steel wire rope 6 facing away from the receiving plate 4 is connected to a lifting device, which is a gantry crane located in the workshop. The first steel wire rope 6 is connected to the steel wire rope of the gantry crane, and then the winch of the gantry crane is started. The winch winds up the first steel wire rope 6. During the winding process, the receiving plate 4 is gradually moved upward. During the movement of the receiving plate 4, the filler material is gradually moved out of the material box 3, thereby reducing the depth of the grab bucket entering the material box 3 and reducing the possibility of the grab bucket colliding with the side wall of the fire channel wall 1.

[0041] Reference Figure 2 and Figure 3 In this embodiment, the first driving component includes a plurality of driving blocks 7 slidably disposed within the receiving plate 4. The driving blocks 7 are located below the receiving seat 5, and each driving block 7 corresponds to a receiving seat 5. A driving rod 8 is disposed on the bottom surface of the receiving seat 5 and is fixedly disposed on the bottom surface of the receiving seat 5. The driving rod 8 enters the receiving plate 4 and abuts against the top surface of the driving block 7. A first steel wire rope 6 at one end of the receiving plate 4 enters the receiving plate 4 and is fixedly connected to the driving block 7. The first steel wire rope 6 slidably passes through the receiving plate 4, and the other end of the first steel wire rope 6 is fixedly disposed on the receiving plate 4. The top surface of the driving block 7 is inclined downward toward the direction of the first steel wire rope 6. The first driving component also includes a second steel wire rope 9 disposed between adjacent driving blocks 7, and the second steel wire rope 9 is in a taut state.

[0042] When the receiving seat 5 is driven to slide, the first steel wire rope 6 is first wound up. The winding of the first steel wire rope 6 causes the drive block 7 to slide. The sliding of the drive block 7 causes the drive rod 8 to slide away from the bottom wall of the material box 3. The drive rod 8 pushes the receiving seat 5 to slide. The operation is simple and convenient. When the drive block 7 moves to the maximum displacement, the first steel wire rope 6 is in a tightened state. Then the winding of the first steel wire rope 6 causes the receiving plate 4 to slide, thereby causing the filler material to move out of the material box 3.

[0043] Reference Figure 2 and Figure 3To facilitate the return of the drive block 7 to its initial position, the first drive component also includes a return component. The return component is used to drive the drive block 7 back to its initial position when the first wire rope 6 is in a slack state. The return component includes a spring 10 disposed in the receiving plate 4. One end of the spring 10 is located on the drive block 7 away from the first wire rope 6 and is fixedly disposed on the drive block 7, and the other end is located in the receiving plate 4 and is fixedly disposed in the receiving plate 4. After the receiving plate 4 is supported by the bottom wall of the material box 3, the first wire rope 6 is in a slack state. Under the elastic force of the spring 10, the drive block 7 is pulled to slide to one side. At the same time, under the gravity of the receiving seat 5, the drive block 7 is driven back to its initial position, which facilitates the receiving seat 5 to support the carbon block.

[0044] Reference Figure 2 and Figure 3 To extend the service life of the first wire rope 6, a first connecting pipe is fixedly installed on the receiving plate 4. The first connecting pipe is a high-temperature resistant pipe, and its length direction is perpendicular to the length direction of the receiving plate 4. The first wire rope 6 is located inside the first connecting pipe and slides within it. The first connecting pipe contains cooling water. The first wire rope 6 is immersed in the cooling water, which keeps the ambient temperature of the first wire rope 6 at around 100 degrees Celsius, effectively reducing the ambient temperature and thus improving the service life of the first wire rope 6.

[0045] Reference Figure 2 and Figure 3 To further reduce the working environment temperature of the first wire rope 6, the first connecting pipe includes an outer pipe and an inner pipe sleeved inside the outer pipe. The first wire rope 6 is located in the inner pipe, and cooling water is contained in the inner pipe and the interlayer between the outer pipe and the inner pipe.

[0046] Reference Figure 4 When the receiving plate 4 moves the filler out of the hopper 3, the powdered filler may fall into the hopper 3 through the gap between the receiving plate 4 and the side wall of the hopper 3. Over time, this will cause the powder to accumulate on the bottom wall of the hopper 3 to be thick, which will easily cause the receiving plate 4 to tilt in the hopper 3. In order to facilitate the stable placement of the receiving plate 4 on the bottom wall of the hopper 3, the bottom wall of the receiving plate 4 is recessed towards the top wall of the receiving plate 4 to form a receiving groove 11. The end face of the side wall of the receiving groove 11 sinks towards the top wall of the receiving plate 4, and the vertical cross section of the side wall of the receiving groove 11 is triangular.

[0047] Reference Figure 4 and Figure 5 To facilitate cleaning of the powder on the bottom wall of the discharge box 3, a plurality of partitions 12 are provided in the receiving trough 11. The partitions 12 are fixedly installed on the bottom wall of the receiving trough 11. The plurality of partitions 12 are parallel to each other and parallel to the width direction of the material box 3. The side walls of the plurality of partitions 12 in the same direction are provided with cleaning plates 13. The cleaning plates 13 are located on the side walls directly opposite the adjacent partitions 12.

[0048] Reference Figure 4 and Figure 5 Furthermore, the cleaning plate 13 is hinged to the partition plate 12, and the extended surfaces of the cleaning plate 13 and the partition plate 12 are intersecting. The hinge axis of the cleaning plate 13 is parallel to the length direction of the partition plate 12. A triangular block 14 is provided on the surface of the cleaning plate 13 near the bottom wall of the material box 3. One corner of the triangular block 14 abuts against the bottom wall of the material box 3. The cleaning plate 13 is slidably disposed on the partition plate 12. The sliding direction of the cleaning plate 13 is parallel to the height direction of the partition plate 12. A third driving member is provided on the partition plate 12 for driving the cleaning plate 13 to slide and rotate, and scraping the impurities on the bottom wall of the material box 3 to the top of the cleaning plate 13. A snap-fit ​​groove for snapping the triangular block 14 is provided on the adjacent partition plate 12.

[0049] Reference Figure 4 and Figure 5 The third driving component includes a lead screw 15 rotatably mounted on the partition 12. The length direction of the lead screw 15 is parallel to the height direction of the partition 12. A mounting block 16 is threaded onto the lead screw 15. The cleaning plate 13 is hinged to the mounting block 16. A spiral spring 17 is sleeved on the lead screw 15. One side of the spiral spring 17 is fixedly mounted on the lead screw 15, and the other side is fixedly mounted on the partition 12. The spiral spring 17 drives the lead screw 15 to have a rotational tendency.

[0050] After the bottom wall of the receiving plate 4 is supported by the bottom wall of the material box 3, the partition plate 12 is also supported by the bottom wall of the material box 3. At this time, the spiral spring 17 drives the lead screw 15 to rotate. The rotation of the lead screw 15 drives the mounting block 16 to slide towards the bottom wall of the material box 3. The sliding of the mounting block 16 drives the cleaning plate 13 to rotate. During the rotation of the cleaning plate 13, it pushes the triangular block 14 to slide towards the adjacent partition plate 12 and abut against the adjacent partition plate 12. After the triangular block 14 abuts against the partition plate 12, one corner of the triangular block 14 is engaged with the partition plate 12, thereby fixing the cleaning plate 13 to the above state. During the rotation of the cleaning plate 13, it scrapes the powder and makes the powder sit on the cleaning plate 13. During the removal of the receiving plate 4, the powder is removed from the material box 3.

[0051] Reference Figure 4 and Figure 5To ensure that the partition 12 and the receiving plate 4 are located on the bottom wall of the material box 3, the spiral spring 17 drives the lead screw 15 to rotate. A locking block 18 is slidably arranged on the partition 12, and a locking block 19 is provided at the end of the lead screw 15. A locking groove 20 is provided on the locking block 18 to engage with the locking block 19. After the locking block 18 slides and disengages from the locking block 19, the lead screw 15 rotates and drives the mounting block 16 to slide. The third driving component also includes a fourth driving component for driving the locking block 18 to slide. The sliding direction of the locking block 18 is parallel to the sliding direction of the partition 12. The fourth driving component includes a plug rod 21 slidably arranged on the partition 12. The sliding direction of the plug rod 21 is parallel to the height direction of the partition 12. When the receiving plate 4 slides toward the bottom wall of the material box 3, the plug rod 21 abuts against the bottom wall of the material box 3, driving the plug rod 21 to slide toward the inside of the partition 12 and abut against the locking block 18, and driving the locking block 18 to disengage from the locking block 19.

[0052] After the partition plate 12 and the receiving plate 4 are both located at the bottom of the material box 3, the plug rod 21 slides towards the partition plate 12 and abuts against the locking block 18. The locking block 18 drives the locking groove 20 to slide, so that the locking block 18 and the locking block 19 are disengaged, thereby releasing the restriction of the locking block 18 on the spiral spring 17, so that the spiral spring 17 can drive the lead screw 15 to rotate.

[0053] The implementation principle of a carbon calcining furnace flue structure in this application embodiment is as follows:

[0054] Before the charcoal blocks are moved into the roasting furnace for firing, filler material is first laid on the receiving plate 4, covering the receiving seat 5. Then, the charcoal blocks are hoisted into the material box 3 and placed on the receiving seat 5. The filler material is then filled into the material box 3 to complete the covering of the charcoal blocks. The charcoal blocks are then fired using natural gas. After the charcoal blocks are fired, the receiving seat 5 is driven to slide by the first driving component. The receiving seat 5 slides away from the bottom of the material box 3, and the receiving seat 5 drives the charcoal blocks to slide toward the opening of the material box 3. During the sliding process, the charcoal blocks push open the filler material covering them. Then, the charcoal blocks are clamped by clamps and removed.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
