At a certain temperature, the water in the biomass material is first evaporated, and then the organic matter begins to decompose and release volatile gases. With the further increase of temperature and the restriction of oxygen, the decomposed substances gradually carbonize to form solid charcoal.

During this process, when the accommodating groove 341 provided on the circumferential side wall surface of the first roller 32 passes through the lower side of the output port of the feeding funnel 61, a bamboo stored in the inner cavity of the feeding funnel 61 falls into the inner cavity of the accommodating groove 341 through the output end of the feeding funnel 61, and moves sideways with the first roller 32 toward the output port of the feeding funnel 61. As the rotation angle of the first roller 32 increases, the bamboo moves from the upper side of the first roller 32 to the lower side of the first roller 32. When the bamboo moves with the rotation of the first roller 32 When it reaches the lower side of the first roller, the extrusion block 342 located in the same accommodating groove 341 as the bamboo slides downward under the action of gravity, thereby crushing the bamboo into multiple strips of bamboo chips; as the first roller 32 further rotates, the pressure block drives the strips of bamboo chips to move toward the tail end of the partition 31 until they pass through the gap between the tail end of the partition 31 and the inner wall of the inner shell 2 and fall into the bottom of the inner cavity of the inner shell 2; according to the above steps, until the first roller 32 crushes all the bamboo in the inner cavity of the storage and loading funnel 61 into strips of bamboo chips and transfers them to the bottom of the inner cavity of the inner shell 2, the first motor 33 stops running.

[0081] After the multiple bamboos stored in the inner cavity of the loading funnel 61 are put into the inner cavity of the inner shell 2, the user reinserts the sealing plug 62 into the port at the output end of the loading funnel 61 to seal the port at the output end of the loading funnel 61. Then, the heating device 4 arranged on the inner wall of the outer shell 1 is started to perform a smoldering and carbonization process on the bamboo strips stored at the bottom of the inner cavity of the inner shell 2. During this process, the steam generated by the bamboo strips is discharged through the multi-way pipe 56.

[0082] After the bamboo strips are smoldered and carbonized to form bamboo charcoal, the second motor 36 drives the second roller 35 to rotate. When the second roller 35 is in the starting position, the guide hole 371 at the head end of the second roller 35 is in a vertical state, and the accommodating cavity 372 at the head end of the second roller 35 is inclined toward the bottom of the inner cavity of the inner shell 2. Figure 6 As shown, in this state, the positioning rod 374 is located at the tail end of the accommodating chamber 372, and the head end of the hammer slide bar 373 abuts against the receiving plate 52. When the second roller shaft 35 rotates 90° counterclockwise, the positioning rod 374 slides from the tail end of the accommodating chamber 372 to the head end of the accommodating chamber 372, and the clamping portion 3742 of the positioning rod 374 extends into the inner cavity of the guide hole 371 and clamps with the positioning groove 3731 provided on the hammer slide bar 373 to position the hammer slide bar 373; as the second roller shaft 35 further rotates counterclockwise, when the rotation angle of the second roller shaft 35 is less than 180°, the hammer slide bar 373 is locked by the positioning rod 374, and the head end of the hammer slide bar 373 always protrudes from the outer surface of the second roller shaft 35, and as the second roller shaft 35 rotates, it is positioned from the lower side of the second roller shaft 35 When the second roller 35 rotates counterclockwise over 180°, the positioning rod 374 is affected by gravity and slides from the head end of the accommodating chamber 372 to the tail end of the accommodating chamber 372. The clamping portion 3742 of the positioning rod 374 is disengaged from the positioning groove 3731 of the hammer slide 373, thereby releasing the lock on the hammer slide 373. Thereafter, the hammer slide 373 is affected by gravity and slides downward along the guide hole 371, hammering the carbonized bamboo strip at the bottom of the inner cavity of the inner shell 2 to produce bamboo charcoal fragments. When the hammer slide 373 hammers the bamboo strip, the receiving plate 52 is impacted by the hammer slide 373 and deflected to one side by a certain angle, so that the produced bamboo charcoal fragments slide along the guide of the receiving plate 52 into the receiving drawer 55. The user can obtain the bamboo charcoal fragments by opening the receiving drawer 55.

[0083] Above, refer to Figures 1 to 9 The intelligent biomass carbonization furnace for laboratory use according to an embodiment of the present invention is described, which has the following beneficial effects:

[0084] 1. The device sets a crushing module in the inner cavity of the inner shell so that it hammers the bamboo strips at the bottom of the inner cavity of the inner shell and has been treated with smoldering carbonization to produce bamboo charcoal fragments. The toughness of the bamboo strips after carbonization is greatly reduced, thereby reducing the energy consumed by the device in the process of crushing bamboo, and solving the problem of high energy consumption in the process of crushing bamboo in the process of preparing bamboo charcoal using the existing technology.

[0085] 2. This equipment utilizes the characteristic that bamboo is prone to longitudinal cracking when subjected to radial external force. By setting a first roller, a first motor and an extrusion assembly, during the rotation of the first roller, the weight of the extrusion block is used to apply radial pressure to the bamboo to crush the bamboo to form regularly shaped strips of bamboo. Under the premise of ensuring the carbonization effect of the bamboo, the extrusion assembly of this equipment can then conveniently carry the strips of bamboo to the bottom of the inner cavity of the inner shell for smoldering carbonization processing, thereby improving the processing efficiency of this equipment.

[0086] 3. The device is provided with a second roller, a second motor and a crushing assembly, so that the second motor continuously increases the gravitational potential energy of the hammer slide bar and releases it during the process of driving the second roller to rotate, and utilizes the gravity of the hammer slide bar to hammer the bamboo strips that have been processed by smoldering and carbonization to produce bamboo charcoal fragments, and utilizes the impact force of the hammer slide bar during the process of hammering the bamboo strips to drive the receiving plate to flip open, so that the bamboo charcoal fragments can fall into the receiving drawer through the unloading window, so as to ensure the airtightness of the inner shell cavity during the smoldering and carbonization of the bamboo strips at the bottom of the inner shell cavity, thereby improving the carbonization effect of the device.
