Description

Technical Field

[0001] The present invention relates to the technical field of renewable resources, and particularly to an intelligent multi-channel biomass carbon and steam co-production device. Background Art

[0002] Biomass carbonization is a type of biomass pyrolysis technology. Currently, according to different product requirements, there are mainly two types: direct combustion internal heating type and indirect wall heating type. The direct combustion internal heating type provides heat for pyrolysis by directly burning biomass raw materials in the reaction vessel. Since the combustion fraction and parameters are uncontrollable, it is suitable for application scenarios with no special requirements for carbon quality. The indirect wall heating type separates the reaction vessel and the heating area, and the inside of the reaction vessel is in an anaerobic state, which is more suitable for producing high-quality biochar. Currently, most of the external heating type carbonization devices are relatively crude and difficult to be large-sized, continuously operated, and precisely controlled.

[0003] The patent with the patent publication number CN110129076B discloses a biomass low-temperature carbon and gas co-production device, a biomass low-temperature carbon and gas co-production device and a carbon and steam co-production method. The biomass low-temperature carbon and gas co-production device includes a feeding device, a fluidized bed carbon and gas co-production furnace body, a biomass carbon reheating device, a gas-solid separation device, a blower, and a biomass carbon cooling and collection device. The biomass low-temperature carbon and steam co-production device further includes a waste heat boiler and a flue gas fan in addition to all the devices of the biomass low-temperature carbon and gas co-production device. This patent has the advantages of high-quality biomass carbon produced and low pyrolysis temperature of biomass raw materials.

[0004] However, this device still has deficiencies: This patent has the advantage of producing high-quality biomass carbon, but it is difficult to timely distinguish raw material blocks with different diameters falling into the carbonization furnace, and when larger raw material blocks fall into the carbonization furnace, it is difficult to timely carry out effective fragmentation treatment, resulting in some larger raw material fragments being difficult to be fully carbonized and fully carry out gas conversion, thus causing resource waste. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides an intelligent multi-channel biomass carbon and steam co-production device, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An intelligent multi-channel biomass carbon and steam co-production device, including a base, a hot blast stove is arranged on the top of the base, a preheating flue is arranged on the right side of the hot blast stove, a carbonization chamber is arranged on the right side of the preheating flue, and a carbonization furnace is arranged on the right side of the carbonization chamber;

[0007] An anti-caking device is arranged inside the carbonization furnace, an anti-settling device is arranged at the bottom of the anti-caking device, and an anti-blocking device is arranged above the anti-settling device;

[0008] The anti-caking device includes an electric rotating rod, the bottom of which is rotatably installed at the center of the bottom inner wall of the carbonization furnace. A reciprocating spiral groove is provided on the outer wall of the top of the electric rotating rod. A sieve plate is penetrated and movably installed on the outer wall of the reciprocating spiral groove of the electric rotating rod. The outer wall of the sieve plate is slidably connected to the inner wall of the carbonization furnace. A fixed ring is fixedly installed on the outer wall of the top of the electric rotating rod. A number of cross bars are fixedly installed at equal intervals on the outer wall of the fixed ring. Rolling rollers are rotatably installed on the outer walls of the cross bars. A telescopic scraping plate is fixedly installed at one end of the cross bar close to the inner wall of the carbonization furnace, and the outer wall of the telescopic scraping plate is in contact with the inner wall of the carbonization furnace. The bottom of the telescopic end of the telescopic scraping plate is located on the movement track of the top of the filter plate. A filter plate is fixedly installed in the middle of the inner wall of the carbonization furnace. A number of pushing plates are slidably installed at equal intervals on the top of the filter plate. Transmission plates are hinged between the tops of the pushing plates and the bottom of the sieve plate. A number of dust-removing mesh plates are fixedly installed at equal intervals on the outer wall of the bottom of the electric rotating rod. U-shaped grooves are provided at the bottoms of the dust-removing mesh plates. When the carbonaceous raw materials that have been preliminarily heated and carbonized in the carbonization chamber enter the interior of the carbonization furnace, the electric rotating rod is started. When the electric rotating rod rotates along the bottom of the inner wall of the carbonization furnace, through the restriction of the built-in block of the sieve plate by the reciprocating spiral groove on its own outer wall, the sieve plate is driven to slide upward and reset along the outer wall of the reciprocating spiral groove of the electric rotating rod. The sieve plate receives the raw materials falling from the top of the carbonization furnace. While the sieve plate drives the raw materials to reciprocate in the vertical direction, during the upward movement of the sieve plate, the bottom of the telescopic end of the sieve plate will contact the bottom of the telescopic scraping plate. At this time, the telescopic end of the telescopic scraping plate contracts towards the inside of its fixed end. And when the electric rotating rod drives the fixed ring to rotate, the fixed ring drives the cross bar to revolve. When the cross bar revolves, it drives the rolling roller to revolve. When the rolling roller revolves, it contacts and rubs against the top of the upward-moving sieve plate. At this time, the rolling roller starts to rotate along the outer wall of the cross bar by friction and rolls and compresses the raw materials during revolution; when the sieve plate moves upward, it pulls the transmission plate to move synchronously. The bottom of the transmission plate is limited by the top of the pushing plate, causing the hinge shaft of itself to start rotating. At this time, the bottom of the transmission plate drives the pushing plate to slide along the edge of the top of the filter plate towards its center direction, and the raw materials falling on the top of the filter plate are evenly dispersed and fall to the bottom of the inner wall of the carbonization furnace through the pushing plate. At the same time, the electric rotating rod drives the dust-removing mesh plate to revolve, and the dust-removing mesh plate rotates and stirs the raw materials.

[0009] According to the above technical solution, a feeding device is provided below the front of the carbonization chamber. A feeding trolley is arranged inside the feeding device. A feeding isolation door is arranged on the front of the carbonization chamber. A material basket assembly is arranged above the periphery of the base. A preheated flue gas control valve is arranged on the front of the carbonization furnace. A carbonization chamber is arranged on the right side of the carbonization furnace. A flue gas-air composite air supply door is arranged on the front of the carbonization chamber. A combustible flue gas control valve is arranged on the back of the carbonization furnace. An intermediate isolation door is arranged on the right side of the carbonization chamber. A cooling area is arranged on the right side of the intermediate isolation door. An outlet isolation door is arranged on the right side of the cooling area. An outlet device is arranged on the right side of the outlet isolation door;

[0010] The back of the carbonization chamber is arranged on the front of the boiler through a pipeline, a U-shaped connecting pipe is arranged on the top of the boiler, an environmental dust removal system is arranged on the left side of the boiler, a main induced draft fan is arranged on the left side of the environmental dust removal system, an energy saver is arranged on the left side of the main induced draft fan, a recirculation fan is arranged on the left side of the energy saver, a recirculation cold flue is arranged on the front side of the cooling zone and the top of the carbonization chamber, and a recirculation hot flue is arranged on the back side of the cooling zone and the top of the carbonization chamber.

[0011] According to the above technical scheme, the anti-sinking device includes a number of friction wheels, a reciprocating screw, a sliding block, an L-shaped combing plate and a number of swinging plates. The several friction wheels are symmetrically and rotatably installed on the inner wall of the U-shaped groove of the dust reduction mesh plate. Both ends of the reciprocating screw are fixedly installed on the side of the friction wheel close to the center of the dust reduction mesh plate. The sliding block penetrates inside and is movably installed on the outer wall of the reciprocating screw. The top carbonization furnace side of the L-shaped combing plate is fixedly installed on the right side of the sliding block. The several swinging plates are equidistantly close to the inner wall of the carbonization furnace and are hinged to the outer wall of the L-shaped combing plate.

[0012] According to the above technical solution, the outer wall of the friction wheel contacts the bottom of the inner wall of the carbonization furnace, the top of the sliding block is slidably installed on the top of the inner wall of the U-shaped groove of the dust reduction mesh plate, the bottom of the L-shaped combing plate contacts the bottom of the inner wall of the carbonization furnace, and a torsion spring is arranged between the swing plate and the L-shaped combing plate. When the dust reduction mesh plate revolves, it drives the friction wheel to revolve along the bottom of the inner wall of the carbonization furnace. When the outer wall of the friction wheel contacts and rubs against the bottom of the inner wall of the carbonization furnace, friction force is generated and the friction wheel starts to rotate. The friction wheel drives the reciprocating screw to rotate, and the reciprocating screw passes through the reciprocating spiral groove on its outer wall. The restriction of the built-in card block of the sliding block can drive the sliding block to move along the outer wall of the reciprocating screw toward the direction close to the electric rotating rod and reset. The sliding block drives the L-shaped combing plate to move synchronously along the bottom of the inner wall of the carbonization furnace. The L-shaped combing plate drives the swinging plate to move synchronously. When the swinging plate's own arc surface contacts the raw material block during the movement, a resistance force is generated. At this time, the hinge shaft of the swinging plate starts to rotate and deflects to the other side of the resisted surface, that is, the swinging plate pushes the raw material block with an inclined surface. When the swinging plate is no longer resisted, it is reset by the torsion spring, and this process repeats reciprocally.

[0013] According to the above technical solution, the anti-sinking device further includes a vertical plate, a corrugated plate, a U-shaped plate and a protective sheet. The bottom of the vertical plate is fixedly installed on the top of the sliding block. The side of the corrugated plate close to the inner wall of the carbonization furnace is fixedly installed on the outer wall of the vertical plate. The bottom of the U-shaped plate is fixedly installed on the top of the vertical plate. The protective sheet is fixedly installed between the top of the U-shaped plate and the outer wall of the electric rotating rod, and the protective sheet is elastic. When the sliding block slides horizontally, it drives the vertical plate to move synchronously. The vertical plate drives the corrugated plate to move synchronously. During the movement, the corrugated plate guides and pushes the raw materials within the revolution range of the dust-removing mesh plate through its own corrugated surface. At the same time, the vertical plate drives the U-shaped plate to move synchronously, and the U-shaped plate drives the protective sheet to move synchronously. Restricted by the electric rotating rod, the U-shaped plate will contact the protective sheet during movement and deform, thereby changing the convexity amplitude.

[0014] According to the above technical solution, the anti-blocking device includes an arc-shaped plate, a chamfered scraper, a hollow plate, a vibrating frame and a through plate. The side of the arc-shaped plate close to the electric rotating rod is fixedly installed on the outer wall of the U-shaped plate. The side of the chamfered scraper away from the electric rotating rod is fixedly installed on the side of the arc-shaped plate close to the electric rotating rod. The side of the hollow plate close to the electric rotating rod is fixedly installed on the outer wall of the arc-shaped plate. The top of the vibrating frame is fixedly installed at the bottom edge of the filter plate. The outer wall of the through plate penetrates and is slidably installed inside the vibrating frame.

[0015] According to the above technical solution, the top of the chamfered scraper contacts the bottom of the filter plate. A spring is arranged between the through plate and the inside of the vibrating frame. The arc surface on the side of the through plate close to the electric rotating rod is located on the movement track of the hollow plate. When the U-shaped plate revolves and moves horizontally, it drives the arc-shaped plate to move synchronously. The arc-shaped plate drives the chamfered scraper to move synchronously along the bottom of the filter plate. The chamfered scraper reciprocally scrapes the bottom of the filter plate. At the same time, the arc-shaped plate drives the hollow plate to move synchronously. During the revolution of the hollow plate, it will impact the through plate to generate vibration. Through the transmission of force, the vibrating frame is driven to vibrate synchronously. And by virtue of the hollow design of the vibrating frame, the vibration effect generated during the impact is amplified. When the hollow plate impacts the arc surface of the through plate, a reaction force will be generated. At this time, the through plate slides along the inner wall of the vibrating frame towards its interior direction through the reaction force and will not block the rotation track of the hollow plate. And the hollow plate will follow the horizontal displacement of the arc-shaped plate. Therefore, the vibration force of the impact is intermittent vibration.

[0016] According to the above technical solution, the anti-blocking device further includes a guide plate, a hook-shaped plate and a friction plate. The top of the guide plate is hinged to the outer wall of the top of the chamfering scraper through a torsion spring. The bottom of the guide plate is in contact with the arc surface of the top of the protective sheet. The top of the hook-shaped plate is hinged to the top of the inner wall of the chamfering scraper. The outer wall of the friction plate is slidably installed on the side of the guide plate close to the arc panel. The side of the friction plate close to the arc panel is hinged to the bottom of the hook-shaped plate. When the chamfering scraper moves horizontally, it drives the guide plate to move synchronously. The bottom of the guide plate is deformed and resisted by the arc surface of the top of the protective sheet. At this time, the hinge shaft at the top of the guide plate starts to rotate and drives the guide plate to move upward gradually along an arc track, that is, the inclination angle of the guide plate is constantly changed. When the inclination angle of the guide plate changes, the friction plate is restricted by the hook-shaped plate, and the top of the hook-shaped plate is limited by the chamfering scraper, prompting the hinge shaft of the hook-shaped plate to start pulling the friction plate to slide along the inclined surface of the guide plate.

[0017] The present invention provides an intelligent multi-channel biomass carbonization and steam co-production device, which has the following beneficial effects:

[0018] (1) Through the cooperation of the carbonization chamber, the feeding device, the feeding trolley, the feeding isolation door, the preheated flue gas control valve, the flue gas and air composite air supply valve, the combustible flue gas control valve, the intermediate isolation door, the carbonization furnace, the cooling zone, the discharging isolation door, the discharging device and the boiler, the present invention realizes a multi-channel parallel arrangement, which are independent of each other, serve as starting heat sources for each other, are controlled in zones, and work together. It can adapt to different materials at the same time, and each channel is arranged in parallel and can operate independently; at the same time, the temperature and carbonization time can be adjusted according to the raw materials. In theory, the raw materials can be changed each time feeding. The carbonization and cooling are integrated design, closely combined, with a compact structure, strong independence and expansion ability. The carbonization zone and the cooling zone are arranged in unit bodies, and can operate independently or in parallel; and during the design stage, the scale can be increased or decreased by simple replication, and during the operation stage, the production capacity can be adjusted by adjusting the number of unit bodies operating simultaneously.

[0019] Through the setting of the anti-caking device, through the cooperation of the electric rotating rod, sieve plate, fixed ring, cross bar, rolling roller, telescopic scraping plate, filter plate, pushing plate, transmission plate and dust reduction mesh plate, the rapid separation and falling of small-diameter raw materials are realized by relying on the reciprocating motion of the sieve plate, which facilitates the rapid carbonization and gas conversion of the raw materials falling to the bottom of the carbonization furnace by itself. At the same time, the rolling roller crushes the large pieces of raw materials received on the top of the sieve plate to avoid resource waste caused by the large pieces being difficult to be fully carbonized and then gas-converted, and the telescopic scraping plate continuously changes the scraping range of the inner wall of the carbonization furnace to avoid the solidification phenomenon of the dust raised when the raw materials fall and adhere to the inner wall of the carbonization furnace, preventing the aggravation of the later maintenance difficulty; and effectively avoiding the centralized accumulation of the vertically falling raw materials at the bottom center of the inner wall of the carbonization furnace, avoiding the reduction of the effect of the dust reduction mesh plate on stirring the raw materials and dispersing their uniform heating and carbonization, and at the same time, the dust reduction mesh plate rotates and adsorbs the powder raised by the raw materials to avoid the powder residue being mixed with the finished carbon and discharged synchronously, reducing the quality of the finished carbon. (2) Through the setting of the anti-bottom-settling device, through the cooperation of the dust reduction mesh plate, friction wheel, reciprocating lead screw, sliding block, L-shaped combing plate, swinging plate, vertical plate, corrugated plate, U-shaped plate and protective piece, relying on the L-shaped combing plate to shovel and dredge the raw materials remaining at the bottom of the inner wall of the carbonization furnace, and at the same time, the swinging plate pushes the raw materials dredged by the L-shaped combing plate away from itself, effectively avoiding the bottom-settling and coking phenomenon of the raw material blocks sticking to the bottom of the inner wall of the carbonization furnace for a long time and on the same side, ensuring the activity of the raw material reaction and avoiding a large amount of smoke generated after coking; at the same time, relying on the corrugated plate to revolve and move horizontally to dredge and push the raw materials in multiple directions, avoiding the mutual stacking and superposition of the raw materials after falling, thereby reducing the flow gap between them, preventing the reduction of the air flow velocity inside the raw materials and thus the reaction efficiency of the carbonaceous raw materials, and at the same time, the protective piece protects the top of the dust reduction mesh plate well during the continuous change of the convex amplitude, and disperses the falling trajectory of the raw materials to a certain extent by relying on the arc surface. (3) Through the setting of the anti-blocking device, through the cooperation of the U-shaped plate, arc-shaped plate, chamfered scraping plate, hollow plate, vibration frame, through plate, guide plate, hook-shaped plate and friction plate, relying on the chamfered scraping plate to realize the revolution and horizontal displacement scraping of the bottom of the filter plate, avoiding the raw material particles being stuck in the filter holes of the filter plate, ensuring the smoothness of the filter holes of the filter plate through the scraping of the chamfered scraping plate and the vibration force of the vibration frame, avoiding the obstruction of the raw material falling rate, and at the same time, the intermittent vibration ensures the smooth movement of the pushing plate, avoiding excessive frictional loss between the pushing plate and the filter plate; and relying on the guide plate with continuously changing inclination angles to conduct fixed-point and quantitative dredging of the falling raw materials, facilitating the stirring of the dust reduction mesh plate and the pushing and dispersion of the corrugated plate, making the powder separation in the raw materials more thorough and the flow gap between the raw materials more sufficient, and then relying on the reciprocating sliding of the friction plate to ensure the cleanliness of one side of the inner wall of the guide plate, preventing the hinge end of the guide plate from being attached with powder and increasing the rotation difficulty of its own angle.

[0044] Temperature increase at the end of the reaction: The temperature of the carbonization chamber 22 is directly adjusted through the flue gas-air composite air supply valve 227, and the oxygen-deficient hot flue gas in the flue is introduced into the carbonization chamber 22 to increase the temperature of the carbonization chamber 22; or ambient air is introduced into the carbonization chamber 22 to promote the spontaneous combustion of the products in the carbonization chamber 22 to increase the temperature of the carbonization chamber 22.

[0045] Heating method for new materials during hot operation: The waste heat of the inner shell is used to preheat the biomass raw materials. Then, by adjusting the opening and closing of the new material carbonization chamber 22 and the combustible flue gas control valve 228, the hot flue gas is led to the flue of the new material carbonization chamber 22 to preheat the biomass raw materials inside.

[0046] Continuous operation and large-scale method: Multiple carbonization chambers 22 operate alternately to keep the entire carbonization furnace 23 in a continuous operation state macroscopically. The alternating logic of the carbonization chambers 22 is compiled to maintain continuous operation.

[0047] At the same time, the carbonization area and the cooling area 231 are designed as a unitary structure and can be continuously increased to achieve large-scale operation. During operation, the production capacity can also be adjusted by adjusting the number of unitary structures operating simultaneously.

[0048] Coordinated control of the boiler 24 and the carbonization furnace 23 system: The heat of the boiler 24 comes from the gaseous and liquid-phase products of carbonization. By adjusting the temperature of the carbonization chamber 22, the ratio of carbon and gaseous and liquid-phase in the carbonization products is adjusted. The boiler 24 automatically makes adaptive adjustments or makes reverse adjustments according to the steam demand. The boiler 24 adjusts the temperature of the recycled flue gas by burning and heat absorption of the heating surface, and the economizer 32 absorbs heat to adjust the cooling rate of the carbon. The cooling area 231 automatically makes adaptive adjustments or makes reverse adjustments according to the carbon outlet temperature demand.

[0049] During use, when the carbonaceous material raw material that has been preliminarily heated and carbonized in the carbonization chamber 226 enters the interior of the carbonization furnace 23, the electric rotating rod 41 is started. When the electric rotating rod 41 rotates along the bottom of the inner wall of the carbonization furnace 23, through the restriction of the built-in block of the sieve plate 42 by the reciprocating spiral groove on its outer wall, the sieve plate 42 is driven to slide upward along the outer wall of the reciprocating spiral groove of the electric rotating rod 41 and reset. The sieve plate 42 receives the raw material falling from the top of the carbonization furnace 23, and drives the raw material to reciprocate in the vertical direction. At the same time, during the upward movement of the sieve plate 42, it will contact the bottom of the telescopic end of the telescopic scraper 46. At this time, the telescopic end of the telescopic scraper 46 contracts towards its fixed end. And when the electric rotating rod 41 drives the fixed ring 43 to rotate, the fixed ring 43 drives the cross bar 44 to revolve. When the cross bar 44 revolves, it drives the rolling roller 45 to revolve. When the rolling roller 45 revolves, it contacts and rubs against the top of the upward moving sieve plate 42. At this time, the rolling roller 45 starts to rotate along the outer wall of the cross bar 44 by friction and rolls and crushes the raw material during its revolution. Through the above cooperation, the rapid separation and falling of the raw material with a small diameter are realized by relying on the reciprocating movement of the sieve plate 42, which is convenient for the carbonization furnace 23 to quickly carbonize the raw material falling to its bottom and convert it into gas. At the same time, the rolling roller 45 crushes and pulverizes the large pieces of raw material received on the top of the sieve plate 42, avoiding the waste of resources caused by the large pieces being difficult to fully carbonize and convert into gas, and the telescopic scraper 46 continuously changes the scraping range of the inner wall of the carbonization furnace 23, avoiding the solidification phenomenon of the dust raised when the raw material falls and adhering to the inner wall of the carbonization furnace 23, preventing the aggravation of the later maintenance difficulty; when the sieve plate 42 moves upward, it pulls the transmission plate 49 to move synchronously. The bottom of the transmission plate 49 is limited by the top of the pushing plate 48, which causes the hinge shaft of itself to start rotating. At this time, the bottom of the transmission plate 49 drives the pushing plate 48 to slide along the top edge of the filter plate 47 towards its center direction, and the raw material falling on the top of the filter plate 47 is evenly dispersed and falls to the bottom of the inner wall of the carbonization furnace 23 through the pushing plate 48. At the same time, the electric rotating rod 41 drives the dust reduction net plate 410 to revolve, and the dust reduction net plate 410 rotates and stirs the raw material. Through the above cooperation, it effectively avoids the centralized accumulation of the vertically falling raw material at the bottom of the inner wall of the carbonization furnace 23, avoiding the reduction of the effect of evenly heating and carbonizing the raw material by the rotation and agitation of the dust reduction net plate 410, and at the same time, the dust reduction net plate 410 rotates and adsorbs the powder raised by the raw material, avoiding the mixing of the powder residue into the finished carbon and being discharged synchronously, reducing the quality of the finished carbon.

[0050] Please refer to Figures 1 - 14 , on the basis of the above embodiments, in another embodiment of the present invention, a sinking prevention device 5 is further included;

[0051] The anti-settling device 5 includes a plurality of friction wheels 51, a reciprocating lead screw 52, a sliding block 53, an L-shaped combing plate 54 and a plurality of swing plates 55. A plurality of friction wheels 51 are symmetrically and rotatably installed on the inner wall of the U-shaped groove of the dust settling screen plate 410. Both ends of the reciprocating lead screw 52 are fixedly installed on the side of the friction wheel 51 close to the center of the dust settling screen plate 410. The sliding block 53 is internally penetrated and movably installed on the outer wall of the reciprocating lead screw 52. The top of the L-shaped combing plate 54 is fixedly installed on the right side of the sliding block 53 on one side of the carbonization furnace 23. A plurality of swing plates 55 are evenly spaced and hinged on the outer wall of the L-shaped combing plate 54 close to the inner wall of the carbonization furnace 23 in sequence.

[0052] The outer wall of the friction wheel 51 contacts the bottom of the inner wall of the carbonization furnace 23. The top of the sliding block 53 is slidably installed on the top of the inner wall of the U-shaped groove of the dust settling screen plate 410. The bottom of the L-shaped combing plate 54 contacts the bottom of the inner wall of the carbonization furnace 23. A torsion spring is arranged between the swing plate 55 and the L-shaped combing plate 54. Through the above cooperation, the raw materials remaining at the bottom of the inner wall of the carbonization furnace 23 are shoveled and guided by relying on the L-shaped combing plate 54. At the same time, the swing plate 55 pushes the raw materials guided by the L-shaped combing plate 54 in the direction away from itself, effectively avoiding the phenomenon of settling and coking due to the long-term contact of the raw material blocks with the bottom of the inner wall of the carbonization furnace 23 on the same side, ensuring the reactivity of the raw material reaction and avoiding the generation of a large amount of smoke after coking.

[0053] The anti-settling device 5 further includes a vertical plate 56, a corrugated plate 57, a U-shaped plate 58 and a protective piece 59. The bottom of the vertical plate 56 is fixedly installed on the top of the sliding block 53. The side of the corrugated plate 57 close to the inner wall of the carbonization furnace 23 is fixedly installed on the outer wall of the vertical plate 56. The bottom of the U-shaped plate 58 is fixedly installed on the top of the vertical plate 56. The protective piece 59 is fixedly installed between the top of the U-shaped plate 58 and the outer wall of the electric rotating rod 41, and the protective piece 59 is elastic. Through the above cooperation, the raw materials are guided and pushed in multiple directions by relying on the revolution and horizontal movement of the corrugated plate 57, avoiding the mutual stacking of the raw materials after falling, thereby reducing the flow gap between them, preventing the reduction of the flow rate of air inside the raw materials and thus the reaction efficiency of the carbonaceous raw materials. At the same time, during the process of the protective piece 59 continuously changing the convex amplitude, it provides good protection for the top of the dust settling screen plate 410, and disperses the falling trajectory of the raw materials to a certain extent by relying on the arc surface.

[0054] When in use, the dust suppression mesh plate 410 drives the friction wheel 51 to revolve along the bottom of the inner wall of the carbonization furnace 23 when it revolves. When the outer wall of the friction wheel 51 contacts and rubs against the bottom of the inner wall of the carbonization furnace 23, friction is generated and the friction wheel 51 starts to rotate. The friction wheel 51 drives the reciprocating screw rod 52 to rotate. The reciprocating screw rod 52 limits the built-in block of the sliding block 53 through the reciprocating spiral groove on its outer wall. The sliding block 53 can be driven to move along the outer wall of the reciprocating screw rod 52 toward the direction close to the electric rotating rod 41 and reset. The sliding block 53 drives the L-shaped combing plate 54 to move synchronously along the bottom of the inner wall of the carbonization furnace 23. The L-shaped combing plate 54 drives the swinging plate 55 to move synchronously. When the arc surface of the swinging plate 55 contacts the raw material block during the movement, a resistance force is generated. At this time, the hinge shaft of the swinging plate 55 starts to rotate and deflects to the other side of the resistance surface, that is, the swinging plate 55 pushes the raw material block with an inclined surface. When the swinging plate 55 is no longer resisted, it is reset by the torsion spring, and the same process is repeated. Through the above cooperation, the raw materials accumulated at the bottom of the inner wall of the carbonization furnace 23 are shoveled and guided by the L-shaped combing plate 54, and at the same time, the swinging plate 55 pushes the raw materials guided by the L-shaped combing plate 54 away from itself. , effectively avoiding the phenomenon of the raw material block sticking to the bottom of the inner wall of the carbonization furnace 23 for a long time and with the same surface, thereby preventing the raw material block from sinking to the bottom and coking, ensuring the activity of the raw material reaction and avoiding the generation of a large amount of smoke after coking; when the sliding block 53 slides horizontally, it drives the vertical plate 56 to move synchronously, and the vertical plate 56 drives the wave plate 57 to move synchronously. During the movement, the wave plate 57 guides and pushes the raw materials within the revolution range of the dust reduction mesh plate 410 through its own wave surface. At the same time, the vertical plate 56 drives the U-shaped plate 58 to move synchronously, and the U-shaped plate 58 drives the protective plate 59 to move synchronously. The protective plate 59 is driven by the electric rotating rod Due to the limitation of 41, the U-shaped plate 58 will resist the protective sheet 59 and deform during the movement, thereby changing the protrusion amplitude. Through the above cooperation, the wave plate 57 revolves and moves horizontally to guide and push the raw materials in multiple directions, so as to avoid the raw materials from piling up and overlapping each other after falling, thereby reducing the flow gaps between each other, and preventing the air circulation speed inside the raw materials from slowing down and thus the reaction efficiency of the carbon material raw materials. At the same time, the protective sheet 59 continuously changes the protrusion amplitude to protect the top of the dust suppression mesh plate 410 well, and relies on the arc surface to disperse the falling trajectory of the raw materials to a certain extent.

[0055] See also Figures 1 - 14 , based on the above embodiment, another embodiment of the present invention further includes an anti-blocking device 6;

[0056] The anti-blocking device 6 includes an arc panel 61, a chamfered scraper 62, a hollow plate 63, a vibrating frame 64, and a through plate 65. The side of the arc panel 61 close to the electric rotating rod 41 is fixedly installed on the outer wall of the U-shaped plate 58. The side of the chamfered scraper 62 away from the electric rotating rod 41 is fixedly installed on the side of the arc panel 61 close to the electric rotating rod 41. The side of the hollow plate 63 close to the electric rotating rod 41 is fixedly installed on the outer wall of the arc panel 61. The top of the vibrating frame 64 is fixedly installed at the bottom edge of the filter plate 47. The outer wall of the through plate 65 penetrates and is slidably installed inside the vibrating frame 64.

[0057] The top of the chamfered scraper 62 contacts the bottom of the filter plate 47. A spring is provided between the through plate 65 and the inside of the vibrating frame 64. The arc surface on the side of the through plate 65 close to the electric rotating rod 41 is located on the movement track of the hollow plate 63. Through the above cooperation, the revolution and horizontal displacement scraping of the bottom of the filter plate 47 are realized by relying on the chamfered scraper 62, avoiding the clogging of raw material particles inside the filter holes of the filter plate 47. The smoothness of the filter holes of the filter plate 47 is ensured by the scraping of the chamfered scraper 62 and the vibration force of the vibrating frame 64, avoiding the obstruction of the raw material falling rate. At the same time, the intermittent vibration ensures the smooth movement of the pushing plate 48, avoiding excessive frictional loss between the pushing plate 48 and the filter plate 47.

[0058] The anti-blocking device 6 further includes a guide plate 66, a hook-shaped plate 67, and a friction plate 68. The top of the guide plate 66 is hinged to the outer wall of the top of the chamfered scraper 62 through a torsion spring. The bottom of the guide plate 66 contacts the arc surface at the top of the protective piece 59. The top of the hook-shaped plate 67 is hinged to the top inner wall of the chamfered scraper 62. The outer wall of the friction plate 68 is slidably installed on the side of the guide plate 66 close to the arc panel 61. The side of the friction plate 68 close to the arc panel 61 is hinged to the bottom of the hook-shaped plate 67. Through the above cooperation, relying on the guide plate 66 with continuously changing inclination angles, the falling raw materials are guided in a fixed-point and quantitative manner, facilitating the agitation of the dust reduction mesh plate 410 and the pushing and dispersion of the corrugated plate 57, promoting more thorough separation of the powder in the raw materials and more sufficient flow gaps between the raw materials. Then, relying on the reciprocating sliding of the friction plate 68, the cleanliness of the inner wall side of the guide plate 66 is ensured, preventing the hinge end of the guide plate 66 from being attached with powder and increasing the difficulty of its own angle rotation.

[0059] During use, when the U-shaped plate 58 rotates around its axis and moves horizontally, it drives the arc-shaped panel 61 to move synchronously. The arc-shaped panel 61 drives the chamfered scraping plate 62 to move synchronously along the bottom of the filter plate 47. The chamfered scraping plate 62 reciprocally scrapes the bottom of the filter plate 47. At the same time, the arc-shaped panel 61 drives the hollow plate 63 to move synchronously. During the revolution of the hollow plate 63, it will impact the through plate 65 to generate vibration. Through the transmission of force, the vibration frame 64 is driven to vibrate synchronously. And by virtue of the hollow design of the vibration frame 64, the vibration effect generated during the impact is amplified. When the hollow plate 63 impacts the arc surface of the through plate 65, a reaction force will be generated. At this time, the through plate 65 slides along the inner wall of the vibration frame 64 towards its interior direction through the reaction force, thus not blocking the rotation trajectory of the hollow plate 63. And the hollow plate 63 will follow the horizontal displacement of the arc-shaped panel 61. Therefore, the vibration force of the impact is intermittent vibration. Through the above cooperation, relying on the chamfered scraping plate 62, the revolution and horizontal displacement scraping of the bottom of the filter plate 47 are realized, preventing raw material particles from getting stuck inside the filter holes of the filter plate 47. Through the scraping of the chamfered scraping plate 62 and the vibration force of the vibration frame 64, the smoothness of the filter holes of the filter plate 47 is ensured, preventing the falling rate of the raw materials from being blocked. At the same time, the intermittent vibration ensures the smooth movement of the pushing plate 48, avoiding excessive frictional loss between the pushing plate 48 and the filter plate 47. When the chamfered scraping plate 62 moves horizontally, it drives the guide plate 66 to move synchronously. The bottom of the guide plate 66 is deformed and resisted by the arc surface at the top of the protective piece 59. At this time, the hinge shaft at the top of the guide plate 66 starts to rotate and drives the guide plate 66 to gradually move upward in an arc-shaped trajectory, that is, the inclination angle of the guide plate 66 is constantly changing. When the inclination angle of the guide plate 66 changes, the friction plate 68 is restricted by the hook-shaped plate 67. The top of the hook-shaped plate 67 is limited by the chamfered scraping plate 62, prompting the hinge shaft of the hook-shaped plate 67 to pull the friction plate 68 to slide along the inclined surface of the guide plate 66. Through the above cooperation, relying on the guide plate 66 with a continuously changing inclination angle, the falling raw materials are guided in a fixed-point and quantitative manner, facilitating the agitation of the dust reduction mesh plate 410 and the pushing and dispersion of the corrugated plate 57, making the separation of the powder in the raw materials more thorough and the flow gap between the raw materials more sufficient. Then, relying on the reciprocating sliding of the friction plate 68, the cleanliness of one side of the inner wall of the guide plate 66 is ensured, preventing the hinge end of the guide plate 66 from being attached with powder, thus increasing the difficulty of rotating its own angle.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
