Abstract
Description
Technical Field
[0001] This utility model relates to the field of pyrolysis furnace technology, and more specifically, it relates to a protective structure for uniform heating of a pyrolysis furnace. Background Technology
[0002] When processing waste tires, they can be refined into oil. When refining waste tires into oil using equipment, a pyrolysis furnace is needed to load and burn the rubber particles, which are then heated into oil and gas.
[0003] In related technologies, a continuous high-efficiency internally heated pyrolysis furnace places the material to be pyrolyzed on a pushing cylinder. The pushing cylinder is pushed towards one end of the feed pipe, allowing the material to enter the kiln body through the feed pipe. After the pushing cylinder pushes the pyrolysis material, it stops in the pushing state, and works with the feed gate and the compacted pyrolysis material to isolate the air. Then, the burner and blower are turned on, and hot air enters the hot air pipe to heat the kiln body (because the hot air pipe has a loop structure, the hot air can circulate several times inside the kiln body, making full use of its heat). At the same time, the power mechanism is started, causing the kiln body to rotate on the base via a rotary wheel. At this time, the front and rear covers rotate with the kiln body, while the other components remain stationary. The material inside the kiln body tumbles inside the kiln body as the kiln body rotates, thus being fully pyrolyzed.
[0004] The existing technical solutions mentioned above have the following drawbacks: when heating the pyrolysis furnace, the furnace is directly heated through the hot gas pipe. During heating, the hot gas cannot be retained and can only be heated by the heat dissipated through the hot gas pipe. Therefore, the heating operation of the pyrolysis furnace is inefficient and the heat is dissipated quickly, resulting in heat waste. Utility Model Content
[0005] (1) Technical problems to be solved
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a protective structure for uniform heating of pyrolysis furnace, which has the feature of rapid heating of pyrolysis furnace.
[0007] (2) Technical solution
[0008] To achieve the above objectives, this utility model provides a protective structure for uniform heating of a pyrolysis furnace, including a support base. The top of the support base is provided with a sliding placement frame, and the top of the placement frame is provided with three storage slots, each of which contains multiple refractory bricks.
[0009] Refractory bricks are used for temperature transfer during heating in pyrolysis furnaces;
[0010] The top of the support base has two sliding grooves, and the bottom of the placement frame is connected to a first slider and a second slider, which are slidably connected in the two sliding grooves respectively.
[0011] A limit component is provided on one side of the second slider;
[0012] The limiting component includes a stop block for blocking and limiting the placement frame.
[0013] When using the protective structure for uniform heating of a pyrolysis furnace according to this technical solution, refractory bricks are arranged in an arc-shaped placement frame to assist in the heating of the pyrolysis furnace. The refractory bricks conduct heat, thereby ensuring that the overall heating temperature of the bottom of the pyrolysis furnace remains consistent. This results in a better melting effect of the rubber particles in the pyrolysis furnace. The placement frame is removed by sliding the first slider and the second slider in the groove. After the placement frame is moved to the use position, it is fixed by a stop block to prevent it from sliding during use.
[0014] Furthermore, support plates are connected to both sides of the top of the support base, and a semi-circular protective shell is connected to the top of the two support plates. Multiple guide plates are connected to the inner wall of the protective shell.
[0015] Furthermore, the placement frame is located between two support plates. The placement frame is arc-shaped and forms a circle with the protective shell. Multiple refractory bricks are evenly arranged inside the placement frame, and due to the limitation of the placement frame, the top of the arranged refractory bricks is arc-shaped.
[0016] Furthermore, the top of the support base is provided with an installation groove, the bottom of the installation groove is connected to a burner, the burner is located below the placement frame, the output end of the burner is connected to the installation base, the installation base is provided with a hot air pipe, the bottom of the storage groove is provided with a working groove, and the hot air pipe is located in the working groove.
[0017] Furthermore, the limiting component includes a first adjusting groove, which is formed on one side of the second slider. A damper is connected to one side of the first adjusting groove, and a first limiting plate is connected to the output end of the damper. A spring is sleeved on the damper, and a stop block is connected to the other side of the first limiting plate.
[0018] Furthermore, a second adjustment groove is provided on one side of the sliding groove of the second slider, and a second limiting plate is slidably connected in the second adjustment groove. A push frame is connected to the side of the second limiting plate away from the first limiting plate. A rotating groove is provided on one side of the second adjustment groove, and a movable shaft is connected in the rotating groove. A push rod is rotatably connected on the movable shaft. One end of the push rod is rotatably connected to one side of the push frame, and the other end of the push rod is connected to a push plate. The push plate is located on one side of the support base.
[0019] (3) Beneficial effects
[0020] In summary, this utility model has the following beneficial effects:
[0021] 1. By setting up a placement frame, storage slot, and refractory bricks, the refractory bricks are simultaneously heated while the pyrolysis furnace is heated through hot gas pipes. The refractory bricks absorb the hot gas, allowing the heat to be maintained for a longer time. Furthermore, the refractory bricks transfer heat, resulting in a more uniform temperature on the surface of the pyrolysis furnace. This leads to better melting of the rubber particles inside the pyrolysis furnace. By setting up a protective shell and baffles, the contact area of the inner wall of the protective shell is increased, and the space between the baffles retains heat, thus improving the heating effect.
[0022] 2. By setting a slide, a first slider, and a second slider, the placement frame is pushed, which facilitates the replacement of refractory bricks in the placement frame. By setting a limiting component, the placement frame placed on the support is limited, which facilitates the use by the staff. Attached Figure Description

[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.
[0033] Example 1:
[0034] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: a protective structure for uniform heating of a pyrolysis furnace, including a support base 1, a sliding placement frame 7 on the top of the support base 1, three storage slots 8 on the top of the placement frame 7, and multiple refractory bricks 9 in each of the three storage slots 8; the refractory bricks 9 are used for temperature transfer during heating of the pyrolysis furnace; two sliding grooves 4 are opened on the top of the support base 1, and a first slider 5 and a second slider 6 are connected to the bottom of the placement frame 7, the first slider 5 and the second slider 6 are slidably connected in the two sliding grooves 4 respectively; a limiting component 15 is provided on one side of the second slider 6; the limiting component 15 includes a stop 154 for blocking and limiting the placement frame 7.
[0035] Specifically, support plates 2 are connected to both sides of the top of the support base 1. A semi-circular protective shell 3 is connected to the top of the two support plates 2. Multiple guide plates 16 are connected to the inner wall of the protective shell 3. The placement frame 7 is located between the two support plates 2. The shape of the placement frame 7 is arc-shaped and forms a circle with the protective shell 3. Multiple refractory bricks 9 are evenly arranged in the placement frame 7. Due to the limitation of the placement frame 7, the top of the arranged refractory bricks 9 is arc-shaped. The top of the support base 1 is provided with an installation groove 11. The bottom of the installation groove 11 is connected to a burner 12. The burner 12 is located below the placement frame 7. The output end of the burner 12 is connected to a mounting base 13. A hot gas pipe 14 is provided on the mounting base 13. A working groove 10 is provided at the bottom of the storage groove 8. The hot gas pipe 14 is located in the working groove 10. By adopting the above technical solution, a space is formed on the support base 1 through the support plate 2 and the protective shell 3, which shields the heat when heating the pyrolysis furnace. The guide plate 16 increases the contact area of the inner wall of the protective shell 3, so that the heat stays between the guide plates 16 for a longer time and reduces heat dissipation. The arc-shaped placement frame 7 and the arc-shaped refractory bricks 9 arranged on the placement frame 7 are closer to the surface of the pyrolysis furnace, so that the temperature of the bottom pyrolysis furnace is kept consistent and the melting effect of rubber particles in the pyrolysis furnace is better.
[0036] Example 2:
[0037] Based on Example 1, please refer to Figure 4 , Figure 5 and Figure 6 .
[0038] Specifically, the limiting component 15 includes a first adjusting groove 151, which is formed on one side of the second slider 6. A damper 152 is connected to one side of the first adjusting groove 151, and a first limiting plate 153 is connected to the output end of the damper 152. A spring 155 is sleeved on the damper 152. A stop block 154 is connected to the other side of the first limiting plate 153. A second adjusting groove 156 is formed on one side of the sliding groove 4 of the second slider 6. A first limiting plate 155 is slidably connected in the second adjusting groove 156. The second limiting plate 157 has a push frame 158 connected to the side of the second limiting plate 157 away from the first limiting plate 153. A rotating groove 159 is opened on one side of the second adjusting groove 156. A movable shaft 1510 is connected in the rotating groove 159. A push rod 1511 is rotatably connected to the movable shaft 1510. One end of the push rod 1511 is rotatably connected to one side of the push frame 158. The other end of the push rod 1511 is connected to a push plate 1512. The push plate 1512 is located on one side of the support base 1. By adopting the above technical solution, through the first adjusting groove 151, spring 155, stop block 154 and second adjusting groove 156, when the placement frame 7 is pushed to move on the support base 1, after the placement frame 7 moves to the use position, the stop block 154 is inserted into the second adjusting groove 156 to block and limit the placement frame 7, so that the placement frame 7 can remain stable during use. Through the push frame 158, push rod 1511, movable shaft 1510 and push plate 1512, it is convenient to replace the refractory brick 9 in the placement frame 7 when it is necessary. By rotating the push rod 1511 on the movable shaft 1510, the second limiting plate 157 slides in the second adjusting groove 156, and pushes out the stop block 154 that extends into the second adjusting groove 156, so that the placement frame 7 can be removed from the support base 1.
[0039] The working principle of this utility model is as follows: During use, the operator places the refractory bricks 9 into the storage slots 8 on the placement frame 7. Multiple refractory bricks 9 are arranged in the storage slots 8, and the shape of the refractory bricks 9 arranged in the storage slots 8 is adjusted to create space in the working slot 10 at the bottom of the storage slots 8. After arranging the refractory bricks 9 in the three storage slots 8 at the top of the placement frame 7, the operator places the placement frame 7 on the support base 1 and places the first slider 5 and the second slider 6 into the two sliding grooves 4 respectively. By pushing the placement frame 7, the operator causes it to slide between the two support plates 2 on the support base 1. The placement frame 7 then causes the first slider 5 and the second slider 6 at the bottom to slide and be limited within the two sliding grooves 4. As the placement frame 7 is fully inserted between the two support plates 2, and the placement frame 7 moves to the predetermined position, the first slider 5 and the second slider 6 gradually move within the two sliding grooves 4. When the second slider 6 moves within the sliding groove 4, the stop block 154 in the first adjustment groove 151 on one side of the second slider 6 slides. When the stop block 154 is blocked by the sliding groove 4 and positioned within the first adjustment groove 151, the stop block 154 blocks the first limiting plate 153, thereby compressing the spring 155 through the first limiting plate 153, causing the spring 155 to undergo elastic deformation. When the stop block 154 enters the second adjustment groove 156, the first spring 155 generates a reverse thrust, pushing the first limiting plate 153, thereby causing the first limiting plate 153 to move within the first adjustment groove. The first adjusting groove 151 slides within the second adjusting groove 156, causing the stop block 154 to slide out within the first adjusting groove 151. Since the first limiting plate 153 and the stop block 154 are a single unit, the first limiting plate 153 is located in the first adjusting groove 151, and one side of the stop block 154 is positioned within the second adjusting groove 156. This is blocked by the second slider 6, which is then limited within the sliding groove 4. This limits the placement frame 7 on the top of the support base 1, facilitating its use. The secure locking of the placement frame 7 ensures greater safety during use, preventing the placement frame 7 from sliding during heating, which could cause the heated refractory brick 9 to slide and injure workers. After the placement frame 7 is installed, the workers... Insert the hot gas pipe 14 into the working slot 10 on the placement frame 7 and screw it onto the mounting base 13 of the burner 12. After installing the hot gas pipe 14, the operator places the pyrolysis furnace for heating rubber granules between the two support plates 2. After the rubber granules are placed into the pyrolysis furnace, the burner 12 operates, and hot gas is sprayed through the hot gas pipe 14 to heat the pyrolysis furnace. During the heating of the pyrolysis furnace, the hot gas surrounds the surface of the pyrolysis furnace and simultaneously heats the refractory bricks 9, causing the refractory bricks 9 to heat up. This allows the hot gas to remain between the pyrolysis furnace and the refractory bricks 9 for a longer time, and the refractory bricks 9 absorb and transfer the heat, thus maintaining a consistent temperature on multiple refractory bricks 9 and ensuring a uniform heating temperature for the pyrolysis furnace.The heating effect on rubber particles inside the pyrolysis furnace is better, and the area of the inner wall of the protective shell 3 is increased by the guide plates 16 on the inner wall of the protective frame. This allows the heat to be retained for a longer time through the space between the guide plates 16, resulting in higher heat utilization efficiency.
[0040] After a period of use, refractory brick 9 may become damaged, requiring replacement. When replacement is needed, after the refractory brick 9 has cooled down, the hot gas pipe 14 can be removed from the mounting base 13. After removal, the operator pushes the push plate 1512, which in turn rotates the push rod 1511 on the movable shaft 1510, causing the push rod 1511 to rotate within the rotating groove 159. The other end of the push rod 1511 pushes the push frame 158, which in turn pushes the second limiting plate 157, causing it to slide within the second adjusting groove 156. This push plate 157 then pushes out the stop block 154 that has entered the second adjusting groove 156, forcing the stop block 154 into place. Within the first adjustment groove 151, the first limiting plate 153 is pushed to move towards the side of the first adjustment groove 151 connected to the spring 155, thereby squeezing the spring 155 through the first limiting plate 153. After the stop block 154 enters the first adjustment groove 151, the operator can push the placement frame 7 to slide on the support base 1. After the stop block 154 moves and is no longer aligned with the second adjustment groove 156, the side wall of the slide groove 4 blocks the stop block 154, keeping the stop block 154 within the first adjustment groove 151, thus preventing the stop block 154 from blocking the placement frame 7. After the operator slides the placement frame 7 out, the operator can replace the refractory brick 9 in the storage groove 8. After replacement, the placement frame 7 is slid and pushed back into the support base 1, and fixed again by the limiting component 15, thus enabling subsequent use.
[0041] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
