Description

Technical Field

[0001] The present application relates to the field of carbonization furnaces, and in particular to a high-efficiency carbonization treatment furnace. Background Art

[0002] The working principle of carbonization furnace is mainly based on pyrolysis technology. In a closed system, wood or other biomass materials are heated and decomposed into combustible gas, wood vinegar and charcoal in an oxygen-deficient environment. This process requires high temperature heating of the raw materials to be carbonized.

[0003] In the related art, a Chinese patent with application number 202121717459.5 proposes to move the raw material to be carbonized in chambers of different temperatures by rotating spiral blades, thereby realizing the process of preheating and carbonizing the raw material to be carbonized;

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the spiral blades will cause the raw materials to be carbonized to move stably in the chamber. When there are a lot of raw materials to be carbonized, the raw materials to be carbonized will accumulate in the gap between the spiral blades and the chamber, and it will be difficult to create space in the raw materials to be carbonized, which will cause the raw materials to be carbonized that are in contact with the inner wall of the chamber to have a fast heat exchange rate, while the raw materials that cannot contact the inner wall of the chamber will have a slow heat exchange rate, which will cause the raw materials to be carbonized to have different heating rates. The different carbonization rates will lead to incomplete carbonization and low carbonization efficiency. Summary of the invention

[0005] In order to improve the problems of incomplete carbonization treatment and low carbonization treatment efficiency, the present application provides a high-efficiency carbonization treatment furnace.

[0006] The present application provides a high-efficiency carbonization treatment furnace adopts the following technical solution:

[0007] A high-efficiency carbonization furnace, comprising

[0008] Low temperature preheating mechanism, used to form a low temperature heat exchange chamber of 200-400℃;

[0009] Medium temperature preheating mechanism, used to form a medium temperature heat exchange chamber of 500-700℃;

[0010] High temperature carbonization mechanism, used to form a high temperature processing chamber of 900-1100°C;

[0011] A feeding assembly, used to allow the raw materials to be carbonized to pass through the low-temperature heat exchange chamber, the medium-temperature heat exchange chamber and the high-temperature treatment chamber in sequence;

[0012] The feeding assembly comprises: a rotating cylinder and a driving mechanism, wherein the driving mechanism is used to drive the rotating cylinder to rotate so that the raw material to be carbonized moves in the low-temperature heat exchange chamber, the medium-temperature heat exchange chamber and the high-temperature treatment chamber;

[0013] A feeding chamber is formed in the rotating cylinder; a plurality of material transport troughs are provided on the inner wall of the rotating cylinder; a plurality of material transport troughs in each group are distributed in a circular array along the axis of the rotating cylinder; each group of material transport troughs can form a circular motion area as the rotating cylinder rotates; along the axis direction of the rotating cylinder, the circular motion areas formed by two adjacent groups of material transport troughs intersect.

[0014] By adopting the above technical scheme, the raw material to be carbonized is preheated before carbonization, so that the raw material to be carbonized is slowly heated up, so that when the raw material to be carbonized enters the high-temperature treatment chamber, the raw material to be carbonized itself has a relatively high temperature, so that the raw material to be carbonized can be quickly heated up in the high-temperature treatment chamber, which is conducive to ensuring the temperature of the high-temperature treatment chamber; in addition, the multiple material transport troughs opened on the rotating cylinder will drive the raw material to be carbonized to be transported through the material transport troughs during the rotation of the rotating cylinder. To be precise, the raw material to be carbonized was originally in one group of material transport troughs, specifically the part of the material transport troughs below the axis of the rotating cylinder. The rotating cylinder rotates, which will cause the material transport troughs to rotate together. When the material transport troughs rotate above the axis of the rotating cylinder, the raw material to be carbonized in the material transport troughs will fall downward under the action of its own gravity, and when the two adjacent groups of material transport troughs intersect, the raw material to be carbonized that falls downward will fall into another group of material transport troughs, thereby realizing the transportation of the raw material to be carbonized. In addition, when the raw materials to be carbonized are transported by falling, the raw materials to be carbonized are in a lifted state in the feeding chamber, which increases the contact range between the raw materials to be carbonized and the air in the feeding chamber, which is beneficial to the rapid heating of the raw materials to be carbonized as a whole. The raw materials to be carbonized fall and contact with the inner wall of the rotating cylinder, which can collide with each other, which is beneficial to the raw materials to be carbonized being broken into multiple small particles by collision, so that the raw materials to be carbonized are more dispersed in the feeding chamber, which is more beneficial to the heating of the raw materials to be carbonized and the carbonization speed.

[0015] Optionally, the material transport trough includes a first material transport surface, a second material transport surface, a third material transport surface and a fourth material transport surface;

[0016] The first material transport surface, the second material transport surface, the third material transport surface and the fourth material transport surface are sequentially connected end to end to form the material transport trough;

[0017] The first material conveying surface, the second material conveying surface, the third material conveying surface and the fourth material conveying surface are all inclined relative to the axis of the rotating drum, and when the material conveying trough is flush with the axis of the rotating drum, the second material conveying surface and the fourth material conveying surface are both inclined downward relative to the axis of the rotating drum;

[0018] When the rotating drum rotates, the first material transporting surface forms a first motion track, the second material transporting surface forms a second motion track, the third material transporting surface forms a third motion track, and the fourth material transporting surface forms a fourth motion track;

[0019] In two adjacent groups of material transport troughs, the first motion trajectory of one group of material transport troughs intersects with the third motion trajectory of the other group of material transport troughs; the second motion trajectories of the two groups of material transport troughs intersect; and the third motion trajectories of the two groups of material transport troughs intersect.

[0020] By adopting the above technical solution, when the rotating drum rotates, when the material transport trough rotates to be inclined relative to the horizontal plane, the second material transport surface and the fourth material transport surface of the material transport trough are both inclined downward relative to the axis of the rotating drum, so that the raw materials to be carbonized in the material transport trough are gathered between the fourth material transport surface and the third material transport surface, and the raw materials to be carbonized can also move in the material transport trough by themselves to the third motion trajectory, and then the third motion trajectory intersects with the first motion trajectory of another material transport trough, so that the raw materials to be carbonized can be directly dropped into another material transport trough, thereby increasing the material transportation speed and ensuring stable transportation of the raw materials to be carbonized.

[0021] Optionally, the high-efficiency carbonization treatment furnace further includes a burner, a first heat transfer mechanism, a second heat transfer mechanism and a recovery mechanism;

[0022] The burner is used to generate heat, and the heat generated by the burner is added to the high temperature treatment chamber;

[0023] The first heat transfer mechanism is used to transfer the heat in the high temperature processing chamber to the medium temperature heat exchange chamber; the second heat transfer mechanism is used to transfer the heat in the medium temperature heat exchange chamber to the low temperature heat exchange chamber;

[0024] The recovery mechanism is used to add the combustible gas generated by the material to be carbonized in the low-temperature heat exchange chamber, the medium-temperature heat exchange chamber and the high-temperature treatment chamber into the burner by means of pipeline transportation.

[0025] By adopting the above technical solution, the heat in the high temperature treatment chamber is reused to maintain the normal operation of the medium temperature heat exchange chamber and the low temperature heat exchange chamber. The recovery mechanism utilizes the combustible gas generated by the carbonization raw material during the carbonization process and adds it to the burner, thereby achieving energy saving effect and better utilizing the energy of the carbonized raw material.

[0026] Optionally, the feeding assembly further comprises an elastic mechanism; a plurality of the elastic mechanisms are provided; the elastic mechanism is provided in the material transport trough;

[0027] The elastic mechanism has a concave state and a convex state;

[0028] A first area and a second area are formed in the rotating cylinder; the first area is a cylindrical area with a minor arc cross section of the rotating cylinder, and the second area is a cylindrical area with a major arc cross section of the rotating cylinder;

[0029] When the material transport trough is located in the first area, the elastic mechanism is in the recessed state; when the material transport trough is located in the second area, the elastic mechanism is in the protruding state;

[0030] When the elastic mechanism is in the recessed state, the elastic mechanism and the material transport trough form a material transport chamber for accommodating the raw material to be carbonized;

[0031] When the elastic mechanism is in the protruding state, the ejection mechanism forms a push surface that partially protrudes outward relative to the material transport chamber;

[0032] When the elastic structure changes from the concave state to the convex state, the push surface moves outward relative to the material transport chamber.

[0033] By adopting the above technical solution, the push surface moves outward relative to the material transport chamber and can push the raw material to be carbonized in the material transport chamber outward. Then, the raw material to be carbonized changes from falling outward to falling outward and being pushed outward, so that the force with which the raw material to be carbonized leaves the material transport trough from the second area and falls onto other material transport troughs or the inner wall of the rotating cylinder is greatly increased, which can increase the force of the raw material to be carbonized colliding with the rotating cylinder, facilitate the fragmentation of the raw material to be carbonized, and thus increase the carbonization speed of the raw material to be carbonized.

[0034] Optionally, the elastic mechanism includes an elastic metal plate and a counterweight;

[0035] The end of the elastic metal plate abuts against the inner wall of the material transport trough; the counterweight block is fixed to the elastic metal plate;

[0036] When the elastic mechanism is in the recessed state, the elastic metal plate is bent away from the axis of the rotating cylinder by the gravity of the counterweight block, so that the elastic metal plate and the material transport trough form a material transport chamber;

[0037] When the elastic mechanism is in the convex state, the elastic force of the elastic metal plate and the gravity of the counterweight block together cause the elastic metal plate to bulge outward to form a curved arc structure;

[0038] The surface of the elastic metal plate forms the push surface.

[0039] By adopting the above technical solution, the elastic metal plate is bent and deformed in a way that the elastic metal plate is in a concave state, and the elastic metal plate is released from the bending deformation in a way that the elastic metal plate is in a convex state. Then, when the elastic metal plate changes from a concave state to a convex state, the force of the pushing surface being pushed outward can be greatly increased under the effect of its own elasticity, so that the force with which the raw material to be carbonized hits the rotating cylinder is greatly increased.

[0040] Optionally, the counterweight is fixedly mounted on the middle or edge of the elastic metal plate.

[0041] By adopting the above technical solution, the elastic metal plate is in a concave state, that is, the elastic metal plate is bent and deformed, and the bending and deformation of the elastic metal plate is caused by the gravity of the counterweight part. Then, when the counterweight part is located in the middle of the elastic metal plate, the elastic metal plate changes from a concave state to a convex state, and the middle part of the elastic plate is concave and convex, so that the thrust applied by the push surface of the elastic metal plate to the raw material to be carbonized is perpendicular to the axis of the rotating drum. When the counterweight part is located at the edge of the elastic metal plate, the deformation degrees on both sides of the bending and deformation position of the elastic metal plate are different. Then, when the elastic metal plate changes from a concave state to a convex state, the direction of the force pushed outward by the push surface is inclined relative to the axis of the rotating drum, so that the raw material to be carbonized can be tilted and pushed into another material transport trough, which can increase the conveying speed of the raw material to be carbonized.

[0042] Optionally, the high-efficiency carbonization treatment furnace further includes a material blocking mechanism and a control mechanism;

[0043] The material blocking mechanism is used to form a material blocking surface at the outlet area of ​​the feeding chamber to block the outlet area of ​​the feeding chamber;

[0044] The control mechanism is used to drive the material blocking mechanism to move so that the material blocking surface and the inner wall surface of the outlet area form a passage for the carbonized material to pass through;

[0045] The control mechanism comprises a driving member and a transmission member, and the driving member enables the material blocking mechanism to move through the transmission member.

[0046] By adopting the above technical solution, the material blocking mechanism blocks the outlet area of ​​the feeding chamber, so the raw material to be carbonized cannot leave the outlet area of ​​the feeding chamber, so the raw material to be carbonized can be automatically fed by the rotating drum and the feeding can be controlled by the material blocking mechanism, so that the raw material to be carbonized is kept in the low-temperature heat exchange chamber, the medium-temperature heat exchange chamber or the high-temperature treatment chamber for a long time, so as to better control the time of the raw material to be carbonized in each chamber, so as to achieve full preheating or full carbonization in any chamber before being discharged, and finally make the carbonization degree more thorough;

[0047] In addition, the rotation speed of the rotating drum can be increased to increase the feeding speed. Since the faster the feeding speed, the higher the frequency of the falling and impact of the raw materials to be carbonized, the raw materials to be carbonized can be better broken into smaller particles, further improving the speed of the carbonization process. At the same time, the blocking surface formed by the blocking mechanism can prevent the raw materials to be carbonized from leaving the low-temperature heat exchange chamber, the medium-temperature heat exchange chamber or the high-temperature treatment chamber, thereby controlling the processing time in the low-temperature heat exchange chamber, the medium-temperature heat exchange chamber or the high-temperature treatment chamber. The raw materials to be carbonized will also hit the blocking surface, further increasing the better breaking of the raw materials to be carbonized into smaller particles, improving the speed of the carbonization process, and making the carbonization degree more thorough.

[0048] Optionally, the material blocking mechanism comprises: a material blocking plate body and a rotating body; the material blocking plate body is used to form the material blocking surface;

[0049] The driving member enables the rotating body to drive the baffle plate body to rotate through the transmission member.

[0050] By adopting the above technical solution, the baffle plate can be opened and closed relative to the feeding channel, and the baffle plate is opened and closed by rotating, and the degree of opening and closing can be controlled.

[0051] Optionally, the material blocking plate body comprises: a supporting portion, a first blocking portion and a second blocking portion;

[0052] The rotating body comprises: a first rotating part and a second rotating part;

[0053] The first rotating part is used to make the first stopper rotatably connected to the support part, and the second rotating part is used to make the second stopper rotatably connected to the support part;

[0054] The first rotating part and the second rotating part are both rotationally matched with the rotating cylinder;

[0055] The driving member drives the first stopper and the second stopper to rotate relative to the supporting portion through the transmission member, the first rotating portion and the second rotating portion at one time.

[0056] By adopting the above technical solution, another method is used to realize that the baffle plate can be opened and closed relative to the feeding channel. The baffle plate is opened and closed by rotating, and the degree of opening and closing can be controlled.

[0057] Optionally, the control mechanism further includes: a first displacement tube, a second displacement tube, and a transmission tube located between the first displacement tube and the second displacement tube; the first displacement tube and the second displacement tube are both located outside the low-temperature heat exchange chamber, the medium-temperature heat exchange chamber, and the high-temperature processing chamber.

[0058] The transmission tube is rotatably connected to the first displacement tube and the second displacement tube;

[0059] The transmission tube is rotatably matched with the rotating cylinder; the driving member sequentially drives the rotating body to drive the baffle plate body to rotate through the first displacement tube, the second displacement tube, the transmission tube and the transmission member.

[0060] By adopting the above technical solution, the opening and closing of the baffle plate can be achieved by controlling the first displacement tube or the second displacement tube, and the baffle plate can be controlled outside the chamber with high temperature, making the implementation method simpler and more reliable.

[0061] In summary, this application includes the following beneficial technical effects:

[0062] By setting up a rotating drum and opening a material transport trough on the rotating drum, all the space in the rotating drum can be used to transport the raw materials to be carbonized, thereby increasing the amount of raw materials transported. The setting of the material transport trough can cause the raw materials to be carbonized to be lifted back and forth in the rotating drum, so that the raw materials to be carbonized can be transported in different material transport troughs. During the replacement process, the raw materials to be carbonized will collide with the inner wall of the rotating drum, so that the raw materials to be carbonized can be broken into small particles, which will greatly increase the heating rate of the raw materials to be carbonized, thereby improving the efficiency of the carbonization treatment and the thoroughness of the carbonization treatment.

DETAILED DESCRIPTION

[0080] The following is combined with Figure 1-16This application is described in further detail.

[0081] A high-efficiency carbonization treatment furnace comprises a low-temperature preheating mechanism 1, a medium-temperature preheating mechanism 2, a high-temperature carbonization mechanism 3 and a feeding assembly 4. The feeding assembly 4 comprises a rotating cylinder 41 and a driving mechanism 42.

[0082] In this embodiment, the low temperature preheating mechanism 1 is a low temperature preheating shell, and a low temperature preheating chamber is formed in the low temperature preheating shell. The medium temperature preheating mechanism 2 is a medium temperature preheating shell, and a medium temperature preheating chamber is formed in the medium temperature preheating shell; the high temperature carbonization mechanism 3 is a high temperature carbonization shell, and a high temperature processing chamber is formed in the high temperature carbonization shell;

[0083] The low temperature preheating mechanism 1 is used to form a low temperature heat exchange chamber of 200-400°C, preferably 300°C. The medium temperature preheating mechanism 2 is used to form a medium temperature heat exchange chamber of 500-700°C, preferably 600°C. The high temperature carbonization mechanism 3 is used to form a high temperature treatment chamber of 900-1100°C, preferably 1000°C.

[0084] The feeding assembly 4 is used to allow the raw materials to be carbonized to pass through the low-temperature heat exchange chamber, the medium-temperature heat exchange chamber and the high-temperature treatment chamber in sequence.

[0085] The feeding assembly 4 includes a rotating drum 41 and a driving mechanism 42. The driving mechanism 42 is used to drive the rotating drum 41 to rotate so that the raw materials to be carbonized move in the low-temperature heat exchange chamber, the medium-temperature heat exchange chamber and the high-temperature treatment chamber.

[0086] Specifically, a feeding chamber is formed in the rotating cylinder 41. A plurality of groups of material transport troughs 411 are provided on the inner wall of the rotating cylinder 41; each group of the material transport troughs 411 is arranged in a circular array along the axis of the rotating cylinder 41; each group of the material transport troughs 411 can form a circular motion area 412 as the rotating cylinder 41 rotates; along the axis direction of the rotating cylinder 41, the circular motion areas 412 formed by two adjacent groups of the material transport troughs 411 intersect. The material transport troughs 411 on the rotating cylinder 41 are blind troughs, so that the raw materials to be carbonized can be normally transported in the rotating cylinder 41. The raw materials to be carbonized in the material transport troughs 411 will fall outwards as the rotating cylinder 41 rotates, and can fall into another group of material transport troughs 411, so that the raw materials to be carbonized can be transported in the rotating cylinder 41 by falling outwards multiple times.

[0087] In this embodiment, the material conveying groove 411 is one of a square blind groove, a circular blind groove, a parallelogram blind groove and a triangular blind groove, among which the parallelogram blind groove is preferred.

[0088] In this embodiment, the driving mechanism 42 includes a driving motor 421 and two meshing gears, one of which is a driving gear 422 connected to the output end of the driving motor 421, and the other gear is a driven gear 423 fixed to the rotating cylinder 41, so that the driving motor 421 drives the rotating cylinder 41 to rotate through the two gears.

[0089] In some embodiments, the low temperature heat exchange chamber, the medium temperature heat exchange chamber and the high temperature processing chamber are connected in sequence. The rotating cylinder 41 passes through the low temperature heat exchange chamber, the medium temperature heat exchange chamber and the high temperature processing chamber in sequence.

[0090] In some other implementation means, the low-temperature preheating shell and the medium-temperature preheating shell are located above the high-temperature carbonization shell, and the high-temperature carbonization shell is misaligned relative to the low-temperature preheating shell and the medium-temperature preheating shell, so that the low-temperature preheating shell, the medium-temperature preheating shell and the high-temperature preheating shell are convenient for daily maintenance and repair. The rotating cylinder 41 runs through the low-temperature preheating shell and the medium-temperature preheating shell. The feeding mechanism also includes: a feeding pipeline 431, a spiral conveying slurry and a rotating motor 432. The feeding pipeline 431 connects the rotating cylinder 41 in the medium-temperature preheating shell with the rotating cylinder 41 in the high-temperature carbonization shell, and the spiral conveying slurry is arranged inside the feeding pipeline 431. The spiral conveying slurry and the feeding pipeline 431 are used to transport the raw materials to be carbonized in the medium-temperature preheating shell to the rotating cylinder 41 of the high-temperature carbonization shell, so that the raw materials to be carbonized pass through the low-temperature preheating chamber, the medium-temperature preheating chamber and the high-temperature carbonization chamber in sequence.

[0091] By adopting the above technical solution, the raw material to be carbonized is preheated before carbonization, so that the raw material to be carbonized is slowly heated up, so that when the raw material to be carbonized enters the high-temperature treatment chamber, the raw material to be carbonized itself has a higher temperature, so that the raw material to be carbonized can be quickly heated up in the high-temperature treatment chamber, which is conducive to ensuring the temperature of the high-temperature treatment chamber. The multiple material transport troughs 411 opened on the rotating cylinder 41 will drive the raw material to be carbonized to be transported through the material transport troughs 411 during the rotation of the rotating cylinder 41. To be precise, the raw material to be carbonized was originally in one of the groups of material transport troughs 411, specifically in the part of the material transport trough 411 below the axis of the rotating cylinder 41. The rotating cylinder 41 rotates, which causes the material transport trough 411 to rotate together. The material transport trough 411 rotates above the axis of the rotating cylinder 41, and then the raw material to be carbonized in the material transport trough 411 will fall downward under the action of its own gravity. When the two adjacent groups of material transport troughs 411 intersect, the raw material to be carbonized that falls downward will fall into another group of material transport troughs 411, thereby enabling the transportation of the raw material to be carbonized. In addition, when the raw material to be carbonized is transported in this falling manner, the raw material to be carbonized is in a lifted state in the feeding chamber, increasing the contact range between the raw material to be carbonized and the air in the feeding chamber, which is beneficial to the rapid heating of the raw material to be carbonized as a whole. The falling raw materials to be carbonized will contact with the inner wall surface of the rotating cylinder 41 and may collide with it, which is conducive to breaking the raw materials to be carbonized into multiple small particles by collision, making the raw materials to be carbonized more dispersed in the feeding chamber, which is more conducive to heating the raw materials to be carbonized and increasing the carbonization speed.

[0092] Specifically, the high-efficiency carbonization treatment furnace further includes a burner 5 , a first heat transfer mechanism 51 , a second heat transfer mechanism 52 and a recovery mechanism 6 .

[0093] The burner 5 is connected to a natural gas pipeline, which delivers natural gas to the burner 5 to generate heat through combustion. The burner 5 is connected to the high temperature treatment chamber through a pipeline. The heat generated by the burner 5 is added to the high temperature treatment chamber.

[0094] The first heat transfer mechanism 51 includes a first heat exchange pipeline 511 and a first blower 512; one end of the first heat exchange pipe is connected to the low-temperature heat exchange chamber, and the other end is connected to the medium-temperature heat exchange chamber, and the output end of the first blower 512 is connected to the first heat exchange pipe. The hot air in the medium-temperature heat exchange chamber passes through the first heat exchange pipeline 511 to reach the low-temperature heat exchange chamber, and the first blower 512 adds the external normal-temperature air to the first heat exchange pipeline 511, so that the external normal-temperature air is mixed with the hot air in the first heat exchange pipeline 511, thereby cooling the hot air, and the temperature in the low-temperature heat exchange chamber is controlled by adjusting the air supply of the first blower 512;

[0095] The second heat transfer mechanism 52 includes a second heat exchange pipeline and a second blower; one end of the second heat exchange pipe is connected to the medium-temperature heat exchange chamber, and the other end is connected to the high-temperature treatment chamber, and the output end of the second blower is connected to the second heat exchange pipe. The hot air in the high-temperature treatment chamber passes through the second heat exchange pipeline to reach the medium-temperature heat exchange chamber, and the second blower adds the external normal-temperature air to the second heat exchange pipeline, so that the external normal-temperature air is mixed with the hot air in the second heat exchange pipeline, thereby cooling the hot air, and the temperature in the medium-temperature heat exchange chamber is controlled by adjusting the air supply of the second blower;

[0096] The recovery mechanism 6 is used to add the combustible gas generated by the materials to be carbonized in the low-temperature heat exchange chamber, the medium-temperature heat exchange chamber and the high-temperature treatment chamber to the burner 5 through pipeline transportation. The recovery mechanism 6 includes an intermediate tank body 61, a gas pipeline 62 and a filter; wherein the gas pipeline 62 is composed of a plurality of pipe bodies, and the gas pipeline 62 is used to connect the intermediate tank body 61 with the feeding chamber in the high-temperature treatment chamber, and also to connect the intermediate tank body 61 with the burner 5. The filter is arranged on the interface between the intermediate tank body 61 and the burner 5, and the filter is used to prevent the raw materials to be carbonized from reaching the burner 5 through the gas pipeline 62.

[0097] The normal operation of the medium-temperature heat exchange chamber and the low-temperature heat exchange chamber is maintained by reusing the heat in the high-temperature processing chamber.

[0098] Specifically, the feeding assembly 4 further includes an elastic mechanism 44; a plurality of the elastic mechanisms 44 are provided; the elastic mechanism 44 is provided in the material transport trough 411; and the elastic mechanism 44 has a recessed state and a protruding state.

[0099] When the elastic mechanism 44 is in the recessed state, the elastic mechanism 44 and the material transport groove 411 form a material transport chamber for accommodating the raw materials to be carbonized; when the elastic mechanism 44 is in the protruding state, the pop-up mechanism forms a push surface that partially protrudes outward relative to the material transport chamber; when the elastic structure changes from the recessed state to the protruding state, the push surface moves outward relative to the material transport chamber.

[0100] The elastic mechanism 44 includes an elastic metal plate 441 and a counterweight 442 ; the end of the elastic metal plate 441 abuts against the inner wall surface of the material transport trough 411 ; and the counterweight 442 is fixed to the elastic metal plate 441 .

[0101] When the elastic mechanism 44 is in the recessed state, the elastic metal plate 441 is bent away from the axis of the rotating cylinder 41 by the gravity of the counterweight block 442, so that the elastic metal plate 441 and the material transport trough 411 form a material transport chamber; when the elastic mechanism 44 is in the protruding state, the elastic force of the elastic metal plate 441 and the gravity of the counterweight block 442 jointly cause the elastic metal plate 441 to protrude outward to form a curved arc structure; the surface of the elastic metal plate 441 forms the push surface.

[0102] The rotating cylinder 41 forms a first area and a second area; the first area is a cylindrical area with a minor arc cross section of the rotating cylinder 41, and the second area is a cylindrical area with a major arc cross section of the rotating cylinder 41; the first area is the lower part of the rotating cylinder 41, and the second area is the entire area of ​​the rotating cylinder 41 outside the first area. In other embodiments, the first area and the second area may both be a rotating cylinder 41 with a semicircular cross section, or the first area is a cylindrical area with a major arc cross section of the rotating cylinder 41, and the second area is a cylindrical area with a minor arc cross section of the rotating cylinder 41.

[0103] When the material transport trough 411 is located in the first area, the elastic mechanism 44 is located in the recessed state; when the material transport trough 411 is located in the second area, the elastic mechanism 44 is located in the protruding state. Among them, regarding the material transport trough 411 being located in the first area and the material transport trough 411 being located in the second area, it is preferred that the material transport trough 411 being located in the first area means that the entire material transport trough 411 is located in the first area, and the material transport trough 411 being located in the second area means that the entire material transport trough 411 is located in the second area. However, there are also some situations where a portion of the material transport trough 411 is located in the first area and a portion of the material transport trough 411 is located in the second area. If the material transport trough 411 moves from the first area to the second area, then the position of the material transport trough 411 at this time is the first area; if the material transport trough 411 moves from the second area to the first area, then the position of the material transport trough 411 at this time is the second area.

[0104] The elastic metal plate 441 is bent and deformed in such a way that it is in a concave state, and the elastic metal plate 441 is released from the bending and deformation in such a way that it is in a convex state. When the elastic metal plate 441 changes from a concave state to a convex state, the force of pushing the pushing surface outward can be greatly increased due to its own elasticity, so that the force with which the raw material to be carbonized hits the rotating cylinder 41 is greatly increased. Example 2

[0105] The difference from Example 1 is:

[0106] Optionally, the material transport trough 411 includes a first material transport surface 411A, a second material transport surface 411B, a third material transport surface 411C and a fourth material transport surface 411D;

[0107] The first material transport surface 411A, the second material transport surface 411B, the third material transport surface 411C and the fourth material transport surface 411D are sequentially connected end to end to form the material transport trough 411;

[0108] The first material conveying surface 411A, the second material conveying surface 411B, the third material conveying surface 411C and the fourth material conveying surface 411D are all inclined relative to the axis of the rotating cylinder 41, and when the material conveying trough 411 is flush with the axis of the rotating cylinder 41, the second material conveying surface 411B and the fourth material conveying surface 411D are both inclined downward relative to the axis of the rotating cylinder 41; Figure 8 .

[0109] When the rotating drum 41 rotates, the first material transporting surface 411A forms a first motion track, the second material transporting surface 411B forms a second motion track, the third material transporting surface 411C forms a third motion track, and the fourth material transporting surface 411D forms a fourth motion track;

[0110] In two adjacent groups of material transport troughs 411, the first motion trajectory of one group of material transport troughs 411 intersects with the third motion trajectory of the other group of material transport troughs 411; the second motion trajectories of the two groups of material transport troughs 411 intersect; and the third motion trajectories of the two groups of material transport troughs 411 intersect.

[0111] When the rotating cylinder 41 rotates and the material transport trough 411 rotates to be inclined relative to the horizontal plane, the second material transport surface 411B and the fourth material transport surface 411D of the material transport trough 411 are both inclined downward relative to the axis of the rotating cylinder 41, so that the raw materials to be carbonized in the material transport trough 411 are gathered between the fourth material transport surface 411D and the third material transport surface 411C, and the raw materials to be carbonized can also move in the material transport trough 411 by themselves to the third motion trajectory, and then the third motion trajectory intersects with the first motion trajectory of the other material transport trough 411, so that the raw materials to be carbonized can be directly dropped into the other material transport trough 411, thereby increasing the material transportation speed and allowing the raw materials to be carbonized to be stably transported. Example 3

[0112] One specific example of the fixation of the counterweight block 442 and the elastic metal plate 441 is: the counterweight block 442 is fixed to the middle part of the elastic metal plate 441 close to the feeding chamber side by welding, and the elastic metal plate 441 is in a recessed state, that is, the elastic metal plate 441 is bent and deformed, and the bending and deformation of the elastic metal plate 441 is caused by the gravity of the counterweight part. Then, when the counterweight part is located in the middle part of the elastic metal plate 441, the elastic metal plate 441 changes from a recessed state to a convex state, and the middle part of the elastic plate is recessed and convex, so that the thrust applied by the push surface of the elastic metal plate 441 to the raw material to be carbonized is perpendicular to the axis of the rotating cylinder 41.

[0113] Another specific example of fixing the counterweight block 442 to the elastic metal plate 441 is: the counterweight block 442 is fixed to the edge of the elastic metal plate 441 close to the feeding chamber by welding, and when the counterweight portion is located at the edge of the elastic metal plate 441, it will cause the elastic metal plate 441 to bend and deform at different degrees on both sides of the position where the deformation degree occurs. Then, when the elastic metal plate 441 changes from a concave state to a convex state, the direction of the force pushing the surface outward is inclined relative to the axis of the rotating cylinder 41, so that the raw material to be carbonized can be tilted and pushed into another material transport trough 411, thereby increasing the conveying speed of the raw material to be carbonized. Example 4

[0114] A specific example of the elastic mechanism 44 being arranged in the material transporting trough 411 is that one end of the elastic metal plate 441 is fixed to one inner wall surface of the material transporting trough 411, and the other end of the elastic metal plate 441 is fixed to another inner wall surface of the material transporting trough 411. In this case, the material transporting trough 411 is a blind trough.

[0115] Another specific example of the elastic mechanism 44 being arranged in the material transport groove 411 is as follows: the difference between this embodiment and embodiment 1 is that the rotating cylinder 41 includes an inner cylinder 413 and an outer cylinder 414, and the inner cylinder 413 is inserted into the outer cylinder 414 to form the rotating cylinder 41. A plurality of material transport grooves 411 are formed on the inner cylinder 413, so that after the inner cylinder 413 is inserted into the outer cylinder 414 to form the rotating cylinder 41, the material transport grooves 411 are blind grooves. The elastic mechanism 44 is fixedly arranged on the outer cylinder 414, wherein both ends of the elastic metal plate 441 are fixed to the inner wall surface of the outer cylinder 414, and after the inner cylinder 413 is inserted into the outer cylinder 414, the plurality of elastic mechanisms 44 on the inner wall surface of the outer cylinder 414 match the plurality of material transport grooves 411 on the inner cylinder 413. Example 5

[0116] The difference from Example 1 is

[0117] The high-efficiency carbonization treatment furnace also includes a material blocking mechanism 7 and a control mechanism 8. The material blocking mechanism 7 is used to form a material blocking surface in the outlet area of ​​the feeding chamber to block the outlet area of ​​the feeding chamber. The control mechanism 8 is used to drive the material blocking mechanism 7 to move so that the material blocking surface and the inner wall surface of the outlet area form a passage for the carbonized material to pass through. The control mechanism 8 includes a driving member 85 and a transmission member 86, and the driving member 85 moves the material blocking mechanism 7 through the transmission member 86.

[0118] The blocking mechanism 7 blocks the outlet area of ​​the feeding chamber, so the raw material to be carbonized cannot leave the outlet area of ​​the feeding chamber, so the raw material to be carbonized can be automatically fed through the rotating cylinder 41 and the feeding can be controlled by the blocking mechanism 7, so that the raw material to be carbonized is in the low-temperature heat exchange chamber, the medium-temperature heat exchange chamber or the high-temperature treatment chamber for a long time, so as to better control the time of the raw material to be carbonized in each chamber, so as to achieve full preheating or full carbonization in any chamber before being discharged, and finally make the carbonization degree more thorough. Increasing the rotation speed of the rotating cylinder 41 to increase the feeding speed, because the faster the feeding speed, the higher the frequency of the falling and impact of the raw material to be carbonized, so that the raw material to be carbonized can be better broken into smaller particles, further improving the speed of carbonization treatment.

[0119] One specific example of the material blocking mechanism 7 is as follows: the material blocking mechanism 7 comprises: a material blocking plate 71 and a rotating body 72; the material blocking plate 71 is used to form the material blocking surface; the driving member 85 drives the rotating body 72 to drive the material blocking plate 71 to rotate through the transmission member 86. The material blocking plate 71 can be opened and closed relative to the feeding channel, and the material blocking plate 71 is opened and closed by rotating, and the degree of opening and closing can be controlled.

[0120] Another specific example of the material blocking mechanism 7 is as follows: the material blocking mechanism 7 includes: a material blocking plate body 71 and a rotating body 72. The material blocking plate body 71 includes: a support portion 711, a first blocking portion 712 and a second blocking portion 713. The rotating body 72 includes: a first rotating portion 721 and a second rotating portion 722. The first rotating portion 721 is used to make the first blocking portion 712 rotatably connected to the support portion 711, and the second rotating portion 722 is used to make the second blocking portion 713 rotatably connected to the support portion 711. The first rotating portion 721 and the second rotating portion 722 are both shaft bodies. The support portion 711 is a plate body, and the first blocking portion 712 and the second blocking portion 713 are both plate bodies. The first rotating portion 721 and the second rotating portion 722 are both rotatably matched with the rotating cylinder 41. Another method is used to realize that the material blocking plate body 71 can be opened and closed relative to the feeding channel, and the material blocking plate body 71 is opened and closed by rotating, and the degree of opening and closing can be controlled.

[0121] The control mechanism 8 further includes: a first displacement tube 81, a second displacement tube 82, and a transmission tube 83 located between the first displacement tube 81 and the second displacement tube 82; and a sleeve 84. The first displacement tube 81 and the second displacement tube 82 are both located outside the low-temperature heat exchange chamber, the medium-temperature heat exchange chamber, and the high-temperature treatment chamber. The transmission tube 83 is rotatably connected with the first displacement tube 81 and the second displacement tube 82; the transmission tube 83 is rotatably matched with the rotating cylinder 41; the driving member 85 sequentially drives the rotating body 72 to drive the material blocking plate body 71 to rotate through the first displacement tube 81, the second displacement tube 82, the transmission tube 83, and the transmission member 86. The sleeve 84 is sleeved on the first displacement tube 81, the second displacement tube 82 and the transmission tube 83. The sleeve 84 is fixed to the first displacement tube 81 and the second displacement tube 82 by screws. When in use, the transmission tube 83 is first placed between the first displacement tube 81 and the second displacement tube 82, and then the first displacement tube 81 and the second displacement tube 82 are fixed by the sleeve 84, so that the transmission tube 83 is located between the first displacement tube 81 and the second displacement tube 82.

[0122] A first specific example of the driving member 85 moving the material blocking mechanism 7 through the transmission member 86 is as follows:

[0123] The driving member 85 is one of a pneumatic cylinder, a hydraulic cylinder and an electric cylinder, and the transmission member 86 includes a transmission rack 861 and a transmission gear 862. A mounting groove for mounting the transmission rack 861 is provided on the transmission tube 83, and the transmission gear 862 is fixed to the rotating body 72, and the transmission gear 862 is meshed with the transmission rack 861. The driving member 85 is used to drive the first displacement tube 81, the second displacement tube 82, the transmission tube 83 and the sleeve 84 to move, so that the transmission tube 83 moves relative to the rotating cylinder 41, and the transmission rack 861 is driven to rotate through the transmission gear 862, and then the transmission gear 862 drives the rotating body 72 and the material blocking plate body 71 to rotate.

[0124] A second specific example of the driving member 85 moving the material blocking mechanism 7 through the transmission member 86 is as follows:

[0125] The driving member 85 is one of a pneumatic cylinder, a hydraulic cylinder and an electric cylinder, and the transmission member 86 includes a first transmission link 863 and a second transmission link 864. The first transmission link 863 is fixed to the rotating body 72, one end of the second transmission link 864 is hinged to the first transmission link 863, and the other end of the second transmission link 864 is hinged to the transmission tube 83. The first transmission link 863, the second transmission link 864, the rotating body 72 and the transmission tube 83 form a crank slider structure, so that the driving member 85 is used to drive the first displacement tube 81, the second displacement tube 82, the transmission tube 83 and the sleeve 84 to move, and the transmission tube 83 moves relative to the rotating cylinder 41, so that the second transmission link 864 drives the first transmission link 863 to rotate, and the first transmission link 863 drives the rotating body 72 and the baffle plate body 71 to rotate.

[0126] A third specific example of the driving member 85 moving the material blocking mechanism 7 through the transmission member 86 is as follows:

[0127] The driving member 85 is one of a pneumatic cylinder, a hydraulic cylinder and an electric cylinder, and the transmission member 86 includes a first contact rod 865, a second contact rod 866 and a torsion spring 867, and the torsion spring 867 is a high temperature resistant spring body. The first contact rod 865 is connected to the driving member 85, the second contact rod 866 is fixed to the rotating body 72, and the torsion spring 867 is arranged on the rotating body 72. Under the action of the torsion spring 867, the rotating body 72 is subjected to the force of the first contact rod 865 approaching the second contact rod 866, and the first contact rod 865 is driven to move by the driving member 85, and the first contact rod 865 pushes the second contact rod 866 to rotate, so that the rotating body 72 rotates, thereby realizing the second contact rod 866 rotating the rotating body 72 and the baffle plate body 71.

[0128] In some embodiments, the material baffle plate 71 is a solid plate or a plate with filtering holes. The material baffle plate 71 is a plate with filtering holes that can first break large particles of the raw materials to be carbonized into small particles before conveying the raw materials to be carbonized.

[0129] In some embodiments, a tapered rod is provided on the material baffle plate 71. When the material baffle plate 71 includes a support portion 711, a first stop portion 712, and a second stop portion 713, two or more tapered rods are provided. When two tapered rods are provided, one tapered rod is provided on the first stop portion 712, and the other tapered rod is provided on the second stop portion 713. When the material baffle plate 71 is a complete circular plate, multiple tapered rods are provided.

[0130] The arrangement of multiple cone rods can make it possible for the raw material to be carbonized to collide with the material baffle plate 71 under the action of the material transport trough 411 and the elastic mechanism 44, and also collide with the cone rod. When it hits the side of the cone rod, the raw material to be carbonized can be better broken due to the small contact area. When two cone rods are arranged, when the first stop 712 and the second stop 713 rotate around the support part 711, the cone rod on the first stop 712 and the cone rod on the second stop 713 collide with each other, thereby causing vibrations on the first stop 712 and the second stop 713, and preventing the raw material to be carbonized from colliding with the material baffle plate 71 and causing adhesion.

[0131] The implementation principle of a high-efficiency carbonization treatment furnace in an embodiment of the present application is as follows: the raw material to be carbonized is added into the low-temperature preheating chamber, and then the driving member 85 drives the rotating cylinder 41 to rotate, and the material conveying trough 411 on the rotating cylinder 41 drives the raw material to be carbonized to be conveyed in the low-temperature preheating chamber, so that the raw material to be carbonized can be conveyed to the medium-temperature preheating chamber, and from the medium-temperature preheating chamber to the feeding pipeline 431, and then conveyed to the high-temperature treatment chamber through the feeding pipeline 431, the rotating motor 432 and the spiral conveying pulp, and finally output from the high-temperature treatment chamber through the rotating cylinder 41.

[0132] The material transport chute 411 will lift the raw materials to be carbonized in the feeding chamber, so that the raw materials to be carbonized will hit the inner wall of the rotating cylinder 41. The elastic mechanism 44 in the material transport chute 411 will increase the force of lifting the raw materials to be carbonized, thereby increasing the force of the raw materials to be carbonized hitting the inner wall of the rotating cylinder 41.

[0133] The control mechanism 8 drives the baffle plate 71 to rotate, so that the baffle plate 71 can block the raw material to be carbonized in the feeding chamber, or can prevent the baffle plate 71 from blocking the raw material to be carbonized in the feeding chamber.

[0134] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
