Description

Technical Field

[0001] This utility model relates to the field of carbonization furnace technology, and in particular to an intermittent litchi wood charcoal firing furnace. Background Technology

[0002] The lychee wood charcoal kiln is a specialized device for converting lychee wood into high-quality charcoal. Through a firing process, the lychee wood is heated and decomposed in an oxygen-deficient environment, resulting in charcoal products with high carbon content, good combustion performance, and a unique aroma.

[0003] Intermittent lychee charcoal kilns operate in batches, completing the loading, firing, and cooling process for one batch of lychee charcoal before proceeding to the next. This highly flexible operating mode allows for adjustments to firing parameters based on actual needs, producing lychee charcoal that meets specific market requirements and caters to diverse customer demands.

[0004] Currently, the connection between the furnace door and the furnace body of the intermittent lychee charcoal kiln is sealed with rubber strips. Under long-term high-temperature conditions, the rubber strips are prone to aging and deformation, leading to seal failure. This disrupts the ideal oxygen-deficient firing environment inside the furnace, resulting in unstable charcoal quality. Existing technology uses high-temperature and corrosion-resistant graphite sealing materials, with an outer layer of ceramic fiber sealing gaskets with a low expansion coefficient. At the same time, high-temperature sealant is applied to all joints in the furnace body to enhance the sealing effect. However, during loading, the lychee wood can only be placed manually inside the furnace. Due to the small space and dim lighting inside the furnace, the wood is unevenly distributed, resulting in poor firing effect and low product qualification rate. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an intermittent lychee wood charcoal kiln, which aims to improve the problem in the existing technology that when loading materials, lychee wood can only be placed manually inside the kiln, resulting in uneven distribution of the wood inside the kiln, poor firing effect, and low product qualification rate.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of an intermittent lychee wood charcoal kiln, including a carbonization furnace 1, which provides a closed space for the firing process. Limiting grooves 3 are provided on the left and right sides of the bottom of the carbonization furnace 1 for limiting. Limiting plates 4 are fixedly connected to the bottom left and right sides of the firing plate 5. The two limiting plates 4 are slidably connected within their respective limiting grooves 3 to ensure stable sliding of the firing plate 5. A lifting base 6 is slidably connected to the bottom of the firing plate 5, allowing adjustment of the height of the firing plate 5. A base plate 7 is fixedly connected to the bottom of the lifting base 6, providing a load-bearing function. Top plates 8 are fixedly connected to the four corners of the bottom of the base plate 7, connecting the base plate 7 to support columns 9. Support columns 9 are fixedly connected to the bottom of multiple top plates 8, supporting the entire device. Connecting plates 10 are fixedly connected to the bottom of multiple support columns 9, connecting the support columns 9 to the outer shell 11. The bottom of multiple connecting plates 10 is provided with an outer shell 11. Each connecting plate 10 has screws 12 rotatably connected around its top, which serves a fastening function. Multiple screws 12 pass through the corresponding connecting plates 10 and are threaded to the top of the corresponding outer shells 11 to achieve a stable connection. Each outer shell 11 has a brake plate 13 fixedly connected to one side. The brake plate 13 can be used to control the braking of the rotating wheel 14 to facilitate the fixing of the device position. Each outer shell 11 has a rotating wheel 14 rotatably connected to its bottom, which allows the entire device to move flexibly. Each of the four corners of the bottom of the carbonization furnace 1 has a support leg 15 fixedly connected to support the carbonization furnace 1. Each of the left and right ends of the front side of the bottom plate 7 has a push rod 16 fixedly connected to it. The push rod 16 facilitates the operator to push the bottom plate 7. Each of the two push rods 16 has the same handle 17 fixedly connected to its front end. The handle 17 provides the operator with a force point to facilitate pushing the device. The front side of the carbonization furnace 1 is provided with an opening and closing mechanism 2. The opening and closing mechanism 2 is used to automatically open and close the door of the furnace to achieve convenient material loading and unloading operations.

[0033] Specifically, when using an intermittent lychee wood charcoal kiln, firstly, the lychee wood to be charred is neatly placed on the charring plate 5 manually. Then, the handle 17 and push rod 16 are used to rotate the wheel 14 at the bottom of the base plate 7. The base plate 7 moves the lifting base 6, and the charring plate 5 moves accordingly, entering the charcoal furnace 1. The lifting base 6 moves downwards, and at this time, the limiting plate 4 slides inside the limiting groove 3. Pulling the handle 17 moves the lifting base 6 outwards. As the temperature rises, the lychee wood begins to char. During this process, the support leg 15 stabilizes the charcoal furnace 1. When the charcoal needs to be removed, the firing plate 5 is pushed by the handle 17 and the push rod 16. The lifting base 6 is inserted into the limit plate 4 and lifted upwards. Then, the firing plate 5 is pulled out by the handle 17. During the movement, the brake plate 13 can brake the wheel 14 when needed to ensure safe operation. By neatly placing the lychee wood on the firing plate 5 outside the furnace, the operator can place the lychee wood neatly and evenly on the firing plate 5 in a well-lit and open space outside the furnace. This avoids working in the small and dark space inside the furnace, effectively solves the problem of uneven distribution of the wood, and improves production efficiency and product quality.

[0034] Reference Figure 1 , Figure 2 and Figure 3The opening and closing mechanism 2 includes two sealing doors 201, which serve to isolate air and heat. Both sealing doors 201 are slidably connected to the front side of the carbonization furnace 1. Locking plates 202 are fixedly connected to the upper and lower sides of both sealing doors 201, providing a locking connection. Corresponding locking blocks 203 are slidably connected to the rear sides of multiple locking plates 202, providing sliding tracks for the locking plates 202 to ensure smooth movement of the sealing doors 201. The rear sides of both locking blocks 203 are fixedly connected to the front side of the carbonization furnace 1, securing the locking blocks 203 to the carbonization furnace 1. A connecting plate 204 is fixedly connected to the top of the upper right end of the locking plate 202, connecting the locking plate 202 to the rack 205 for power transmission. The rack 205 is fixedly connected to the left end of the connecting plate 204. Driven by the drive gear 209, rack 1 205 drives the right sealing door 201 to move. A connecting block 206 is fixedly connected to the top of the upper left end locking plate 202. The connecting block 206 is used to connect the locking plate 202 and rack 2 207. A motor 208 is fixedly connected to the top of the carbonization furnace 1. The motor 208 serves as a power source to provide power for the opening and closing of the sealing door 201. The output end of the motor 208 is fixedly connected to the drive gear 209. The drive gear 209 converts the rotational motion of the motor 208 into linear motion, driving rack 1 205 and rack 2 207 to move. The drive gear 209 meshes with rack 1 205 and rack 2 207 respectively. Through the meshing of the gear and rack, the synchronous opposite and reverse movements of the two sealing doors 201 are realized, thereby controlling the opening and closing of the front opening of the carbonization furnace 1.

[0035] Specifically, when the furnace door needs to open and close automatically, the motor 208 starts, and its output drives the drive gear 209 to rotate. The top of the upper right end locking plate 202 is fixedly connected to rack one 205 through connecting plate 204, and the top of the upper left end locking plate 202 is fixedly connected to rack two 207 through connecting block 206. Since the drive gear 209 meshes with rack one 205 and rack two 207 respectively, as the drive gear 209 rotates, rack one 205 and rack two 207 will produce linear movements in opposite directions. When the drive gear 209 rotates clockwise, it meshes with them. When rack 1 205 moves to the right, it causes the right sealing door 201 to slide to the right. At the same time, rack 2 207 moves to the left, causing the left sealing door 201 to slide to the left. At this time, the sealing door 201 is open. When motor 208 reverses and drive gear 209 rotates counterclockwise, rack 1 205 moves to the left and rack 2 207 moves to the right. The two sealing doors 201 slide towards each other, thus closing the sealing door 201. During this process, locking plate 202 and locking block 203 cooperate with each other to prevent the sealing door 201 from shifting or shaking during the sliding process, ensuring the smoothness and accuracy of the opening and closing action.

[0036] Reference Figure 1 , Figure 3 and Figure 4 Multiple screws 12 are rotatably connected to washers 18 on their outer walls. Washers 18 can increase the contact area between screws 12 and connecting plates 10 and distribute pressure. The bottom of multiple washers 18 is respectively attached to the top of the corresponding connecting plates 10, which plays a role in stabilizing the connection and preventing loosening. The top of the firing plate 5 is fixedly connected to the surrounding area of ​​the top of the plate 5. The plate 19 is used to prevent the litchi wood from rolling off during the firing process. The plate 19 is made of stainless steel to ensure that the plate 19 has good corrosion resistance and strength. The top of the bottom plate 7 is fixedly connected to the rear side of the top of the bottom plate 7. The triangular block 20 plays a role in supporting and strengthening the structural stability. The top of the triangular block 20 is fixedly connected to the bottom of the lifting base 6, further stabilizing the connection between the lifting base 6 and the bottom plate 7. The right side of the carbonization furnace 1 is fixedly connected to the controller 21. The controller 21 is electrically connected to the motor 208 to realize precise control of the operating status of the motor 208.

[0037] Specifically, the gasket 18 increases the contact area between the screw 12 and the connecting plate 10, which can distribute the pressure more evenly when tightening the screw 12, avoiding excessive local stress on the connecting plate 10 and preventing damage. At the same time, it effectively prevents the screw 12 from loosening and enhances the stability of the connection between the connecting plate 10 and the outer shell 11. The protective plate 19 can prevent the litchi wood from falling off the firing plate 5 due to rolling and displacement during the firing process, ensuring the smooth progress of the carbonization process. Since the protective plate 19 is made of stainless steel, it has good corrosion resistance and can withstand high temperature and chemical corrosion environments. The triangular block 20 uses the stability principle of triangles to provide additional support for the lifting base 6. The top of the triangular block 20 is fixedly connected to the bottom of the lifting base 6, which strengthens the connection strength between the base plate 7 and the lifting base 6. The controller 21, as the control center of the equipment, integrates various control circuits and operating interfaces. The controller 21 is electrically connected to the motor 208, and the operator can precisely control the motor 208 through the controller 21.

[0038] Working principle: When using the intermittent lychee wood charcoal kiln, firstly, the lychee wood to be charred is neatly placed on the charring plate 5 manually. The handle 17 and push rod 16 push the wheel 14 at the bottom of the base plate 7 to rotate, causing the base plate 7 to move the lifting base 6. The charring plate 5 also moves accordingly, entering the charcoal furnace 1. The lifting base 6 moves downwards, at which point the limiting plate 4 slides inside the limiting groove 3. Pulling the handle 17 moves the lifting base 6 outwards. As the temperature rises, the lychee wood begins to char. During this process, the support leg 15 stabilizes the charcoal furnace 1. When the charcoal needs to be removed, the firing plate 5 is pushed by the handle 17 and the push rod 16. The lifting base 6 is inserted into the limit plate 4 and lifted up. Then the firing plate 5 is pulled out by the handle 17. During the movement, the brake plate 13 can brake the wheel 14 when needed to ensure safe operation. By neatly placing the lychee wood on the firing plate 5 outside the furnace, the operator can place the lychee wood neatly and evenly on the firing plate 5 in a well-lit and open space outside the furnace. This avoids working in the small and dark space inside the furnace, effectively solves the problem of uneven distribution of the wood, and improves production efficiency and product quality.

[0039] Furthermore, when the furnace door needs to open and close automatically, the motor 208 starts, and its output drives the drive gear 209 to rotate. The top of the upper right end locking plate 202 is fixedly connected to rack one 205 via connecting plate 204, and the top of the upper left end locking plate 202 is fixedly connected to rack two 207 via connecting block 206. Since the drive gear 209 meshes with rack one 205 and rack two 207 respectively, as the drive gear 209 rotates, rack one 205 and rack two 207 will produce linear movements in opposite directions. When the drive gear 209 rotates clockwise, the meshing racks... When rack 1 205 moves to the right, it causes the right-side sealing door 201 to slide to the right. At the same time, rack 2 207 moves to the left, causing the left-side sealing door 201 to slide to the left. At this time, the sealing door 201 is open. When motor 208 reverses and drive gear 209 rotates counterclockwise, rack 1 205 moves to the left and rack 2 207 moves to the right. The two sealing doors 201 slide towards each other, thus closing the sealing door 201. During this process, locking plate 202 and locking block 203 cooperate with each other to prevent the sealing door 201 from shifting or shaking during the sliding process, ensuring the smoothness and accuracy of the opening and closing action.
