Technical Field

[0001] This application relates to the field of biomass carbonization technology, and in particular to a horizontal continuous biomass carbonization furnace. Background Technology

[0002] Biomass energy, with its characteristics of being renewable, low-pollution, widely distributed, and abundant, has become an important research direction for global energy transformation. Currently, mainstream biomass energy conversion technologies cover multiple pathways such as gasification, carbonization, direct combustion power generation, liquefaction, and biogas production. Among them, biomass carbonization technology stands out due to its multi-dimensional value advantages. This technology achieves the targeted removal of moisture, oxygen, and some carbon components from biomass raw materials by pyrolyzing them in a limited or anaerobic environment.

[0005] In existing technologies, undehydrated biomass can easily enter the main body of the carbonization furnace, and during the dehydration process of the biomass, the drain outlet can easily become clogged, affecting the efficiency of the operation. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the easy entry of undehydrated biomass into the carbonization furnace body and the easy clogging of the drain outlet during the dehydration process of biomass, which affects work efficiency. Therefore, a horizontal continuous biomass carbonization furnace is proposed.

[0007] The horizontal biomass continuous carbonization furnace provided in this application adopts the following technical solution: A horizontal biomass continuous carbonization furnace, comprising: The housing and the feed hopper located on one side of the top of the housing; The dehydration device is located inside the chamber; A sealing mechanism is installed on the dehydration mechanism; The carbonization device is located inside the enclosure; The anti-clogging mechanism is located inside the enclosure.

[0008] Furthermore, the dehydration device includes an inclined plate disposed inside the chamber, a frame fixedly connected to one side of the inclined plate, a base movably connected inside the frame, a dehydration tank fixedly connected inside the chamber, a hydraulic cylinder fixedly connected to the bottom inside the dehydration tank, and a pressure plate fixedly connected to the output end of the hydraulic cylinder.

[0009] Furthermore, the carbonization mechanism includes a carbonization furnace body disposed inside the box, a guide plate rotatably connected between the carbonization furnace body and the frame, an ignition device disposed at the bottom of the carbonization furnace body, a vacuum pump disposed on one side inside the box, and a pipe fixedly connected to the output end of the vacuum pump, the pipe being fixedly connected to the carbonization furnace body.

[0010] Furthermore, a motor is fixedly installed on the rear side of the box body, a stirring rod is rotatably connected inside the main body of the carbonization furnace, four connecting plates are fixedly connected to the outer surface of the stirring rod, and the output shaft of the motor is fixedly connected to the stirring rod.

[0011] Furthermore, the sealing mechanism includes an inlet located on one side of the dehydration tank, a recycling trough 1 located on the top of the inlet, a sealing plate 1 slidably connected inside the recycling trough 1, a rack 1 fixedly connected to one side of the sealing plate 1, a gear 1 meshing with the rack 1, a rotating rod 2 fixedly connected to the gear 1, and the rotating rod 2 rotatably connected to the recycling trough 1.

[0012] Furthermore, a rack two is fixedly connected to the top of the pressure plate, a gear two is meshed with the rack two, a rotating rod three is fixedly connected to the gear two, the rotating rod three is rotatably connected to the dehydration box, and a sprocket two and a sprocket one are fixedly connected to the rear ends of the rotating rod three and the rotating rod two, respectively, and the same chain one is meshed with the sprocket two and the sprocket one.

[0013] Furthermore, the anti-clogging mechanism includes multiple drain outlets located on one side of the top of the base, a collection box located on the bottom inside the housing, a protective block fixedly installed inside the collection box, a second motor fixedly installed on one side inside the housing, a rotating column fixedly connected to the output shaft of the second motor, and a first cam and a second cam fixedly connected to the outer surface of the rotating column.

[0014] Furthermore, the second cam is located inside the protective block. Cam grooves are provided around the periphery of both the first cam and the second cam, and reciprocating rods are slidably connected in the cam grooves. A vibrating plate is rotatably connected to one of the reciprocating rods, and the vibrating plate is fixedly connected to the base.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. This solution activates a hydraulic cylinder, which drives the pressure plate downwards, simultaneously moving the rack and pinion downwards. Through this linkage, the gear drives the rack and pinion downwards, causing the sealing plate to move downwards and close the inlet. This allows the pressure plate to squeeze and dehydrate the biomass. Closing the inlet prevents undehydrated biomass from continuously entering the dehydration tank and accumulating on the pressure plate during the dehydration process, thus improving work efficiency. 2. This solution starts the second motor, whose output shaft drives the rotating column to rotate. The rotating column drives the first and second cams to rotate, causing one of the reciprocating rods to drive the vibrating plate to move up and down repeatedly, thus vibrating the base and accelerating the entry of biomass into the carbonization furnace body. This also prevents biomass from adhering to the base and improves the feeding efficiency. At the same time, the other reciprocating rod drives the bottom plate and column to move upward continuously, allowing multiple columns to clear the drain outlet and prevent biomass from getting stuck in the drain outlet during the feeding process. 3. This solution starts motor one, whose output shaft drives rotating rod four to rotate, and through linkage, opens the discharge port. Simultaneously, rotating rod four drives one of the sprockets three to rotate, and through linkage, sealing plate three slides open, allowing the dewatered biomass to enter the carbonization furnace body through the inclined base and guide plate. After feeding is complete, starting motor one in reverse will simultaneously close sealing plate three and sealing plate two, preventing biomass from accumulating on the guide plate. The setting of sealing plate two will not affect the dewatering treatment of the next batch of biomass, greatly improving work efficiency.

[0016] This invention can prevent undehydrated biomass from entering the carbonization furnace and can also clear the dehydration port to prevent biomass from getting stuck in it, thereby improving work efficiency. Attached Figure Description

The same chain 27 is meshed with the sprocket 26 and the sprocket 22.

[0034] The implementation principle of a horizontal biomass continuous carbonization furnace in this application embodiment is as follows: Biomass is poured into the feed hopper 2 and then enters the dewatering tank 5 through the inclined plate 3. By starting the hydraulic cylinder 6, the hydraulic cylinder 6 drives the pressure plate 7 to move downward, and at the same time drives the rack 23 to move downward. The rack 23 drives the gear 24 to rotate, the gear 24 drives the rotating rod 25 to rotate, the rotating rod 25 drives the sprocket 26 to rotate, the sprocket 26 drives the sprocket 22 to rotate through the chain 27, the sprocket 22 drives the rotating rod 21 to rotate, the rotating rod 21 drives the gear 20 to rotate, the gear 20 drives the rack 19 to move downward, so that the sealing plate 18 moves downward to close and seal the inlet. Since the rack 23 is relatively short, the sealing plate 18 closes first, and then the pressure plate 7 contacts the biomass and squeezes and dewaters it. During the extrusion process, water can enter the collection box through multiple drains 44. At the same time, during the discharge process, the second motor 38 is started. The output shaft of the second motor 38 drives the rotating column to rotate. The rotating column drives the first cam 39 and the second cam 41 to rotate, so that one of the reciprocating rods drives the vibrating plate 40 to move up and down repeatedly, which can vibrate the base 8. At the same time, the other reciprocating rod drives the base plate 42 and the column 43 to move upward continuously, so that multiple columns 43 can clear the drains 44 and prevent biomass from getting stuck in the drains 44 during the discharge process. Then, by starting the motor 14, the output shaft of the motor 14 drives the rotating rod 31 to rotate, which in turn drives the gear 30 to rotate. The rotation of the gear 30 drives the rack 29 to move upward, and at the same time, it drives the sealing plate 28 to move upward, opening the discharge port. Simultaneously, the rotating rod 31 drives one of the sprockets 32 to rotate, and the sprocket 32 ​​drives the other sprocket 32 ​​to rotate via the chain 2. This causes the rotating rod 15 to drive the gear 33 to rotate, which in turn drives the gear 5 34 to rotate. The rotation of the gear 5 34 causes the rack 36 to slide, causing the sealing plate 37 to slide open. This allows the dehydrated biomass to enter the carbonization furnace body 10 through the inclined base 8 and guide plate 9. After feeding is completed, the motor 14 is started in reverse, which simultaneously closes the sealing plate 37 and the sealing plate 28. Then, the vacuum pump 12 extracts the air from the carbonization furnace body 10, making the carbonization furnace body 10 a vacuum state. Then, combustion is initiated by the ignition device 11. Example 2

[0035] The difference between this embodiment and embodiment one is that a valve is installed inside the feed hopper 2 to prevent dust from entering the device through the feed hopper 2 when the device is idle, thus affecting the use of the device.
