Description

Technical Field

[0001] This utility model relates to the field of carbonization furnace technology, specifically a vertical carbonization furnace. Background Technology

[0002] A carbonization furnace is a thermal device that uses oxygen-limited heating to convert carbonaceous raw materials (such as wood, fruit shells, straw, etc.) into carbon compounds (biochar, charcoal, activated carbon precursors, etc.) in an oxygen-free or oxygen-deficient environment. Some existing devices exist, such as the one described in announcement number CN215828687U: an energy-saving and environmentally friendly single-tube vertical carbonization furnace, comprising a base, a furnace box at the top of the base, condenser pipes on the inner wall of the furnace box, insulation cotton on the inner wall of the condenser pipes, a carbon bin inside the insulation cotton, a furnace cover at the top of the carbon bin, a burner at the bottom of the carbon bin, and a filter pipe on the right side of the furnace box. When the carbonization furnace is used, the combination of the burner and the carbon bin allows for efficient and complete combustion of the material.

[0003] Although the above-mentioned device achieves the harmless treatment of exhaust gas, in actual use, the exhaust gas contains a large amount of heat. The device does not optimize the exhaust gas path, resulting in the waste of heat in the exhaust gas, which further reduces the heat recovery efficiency of the device. Utility Model Content

[0004] The purpose of this invention is to provide a vertical carbonization furnace to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vertical carbonization furnace includes a mounting base, a burner is placed on the upper surface of the mounting base, a carbonization cylinder is embedded and connected to the upper surface of the mounting base, and a placement box is fixedly connected to one side of the mounting base.

[0007] A drive mechanism is fixedly connected to the upper surface of the placement box. The drive mechanism includes a lower housing, an upper housing, a hydraulic cylinder, a limiting block, a gear, and a heat-insulating pipe. The lower housing is fixedly connected to the upper surface of the placement box, and the upper housing is embedded in the upper surface of the lower housing. The hydraulic cylinder is threadedly connected to the side surfaces of the lower housing and the upper housing. A rack is fixedly connected to the output end of the hydraulic cylinder. The limiting block is fixedly connected to the upper surface of the lower housing. The rack and the limiting block are slidably connected. The heat-insulating pipe is rotatably connected to the upper surface of the placement box and passes through the lower housing and the upper housing. The gear is fixedly connected to the outer surface of the heat-insulating pipe. The rack and the gear are meshed together. A water tank is placed inside the placement box.

[0008] Furthermore, the outer surface of the insulation pipe is fixedly connected to a box door, the outer surface of the box door is provided with an air vent communicating with the insulation pipe, a filter box is fixedly connected inside the placement box, a fan is embedded in the outer surface of the filter box, activated carbon filter material is placed inside the filter box, and a door is hinged to the outer surface of the filter box and the activated carbon filter material at the corresponding positions.

[0009] Furthermore, the outer surface of the water tank is provided with a channel, a slide rail is fixedly connected to the outer surface of the channel, a first partition is slidably connected inside the slide rail, and a second partition is slidably connected inside the slide rail.

[0010] Furthermore, the lower surface of the mounting base is fixedly connected with a support leg for supporting the mounting base.

[0011] Furthermore, the side surface of the burner is connected by bolts to a first valve for controlling the gas path.

[0012] Furthermore, a channel tube is fixedly connected to the upper surface of the carbonization cylinder, a connection notch is provided on the upper surface of the carbonization cylinder, and a cover is fixedly connected to one end of the heat insulation tube.

[0013] Furthermore, the upper surface of the water tank is connected by bolts to a second valve for controlling the flow of water, and the lower surface of the channel is connected to a water outlet pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The gears rotate the insulation tube, causing the door to seal the placement box and the cover to seal the carbonization cylinder, so that the door opens simultaneously when the cover is opened, facilitating the later adjustment of the positions of the first and second partitions;

[0016] 2. Both the first and second baffles can slide left and right within the slide rail. When the two baffles are alternately inserted into the channel, an "S"-shaped or multiple-fold flue gas path can be formed within the channel, significantly extending the residence time of the flue gas in the water. Similarly, when the first and second baffles are on the same side, the flue gas flow is smoothest, making the flue gas path adjustable, which facilitates improving the efficiency of the water tank in absorbing heat and realizing the recovery and reuse of some heat.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 In this embodiment of the utility model, a vertical carbonization furnace includes a mounting base 1, a burner 2 is placed on the upper surface of the mounting base 1, a carbonization cylinder 3 is embedded and connected to the upper surface of the mounting base 1, and a placement box 7 is fixedly connected to one side of the mounting base 1.

[0024] A drive mechanism 5 is fixedly connected to the upper surface of the placement box 7. The drive mechanism 5 includes a lower housing 501, an upper housing 502, a hydraulic cylinder 503, a limiting block 504, a gear 506, and a heat-insulating pipe 507. The lower housing 501 is fixedly connected to the upper surface of the placement box 7, and the upper housing 502 is embedded in the upper surface of the lower housing 501. The hydraulic cylinder 503 is threadedly connected to the side surfaces of the lower housing 501 and the upper housing 502. A rack 505 is fixedly connected to the output end of the hydraulic cylinder 503. The limiting block 504 is fixedly connected to the upper surface of the lower housing 501. The rack 505 and the limiting block 504 are slidably connected. The heat-insulating pipe 507 is rotatably connected to the upper surface of the placement box 7 and passes through the lower housing 501 and the upper housing 502. The gear 506 is fixedly connected to the outer surface of the heat-insulating pipe 507. The rack 505 and the gear 506 are meshed. A water tank 8 is placed inside the placement box 7.

[0025] Specifically, during use, firewood is placed into the carbonization cylinder 3, and then the hydraulic cylinder 503 is activated. The output end of the hydraulic cylinder 503 drives the rack 505 to move. The limit block 504 limits the movement of the rack 505. Driven by the rack 505, the gear 506 causes the heat preservation tube 507 to rotate, so that the door 701 seals the box 7 and the cover 6 seals the carbonization cylinder 3. This allows the door 701 to open simultaneously when the cover 6 is opened, facilitating the later adjustment of the positions of the first partition 803 and the second partition 804. The burner 2 is connected to an external gas pipe, and the operation of the burner 2 carbonizes the firewood in the carbonization cylinder 3.

[0026] Example 1

[0027] like Figure 1-4 As shown, a box door 701 is fixedly connected to the outer surface of the insulation pipe 507. An air vent 702 communicating with the insulation pipe 507 is opened on the outer surface of the box door 701. A filter box 703 is fixedly connected inside the box 7. A fan 704 is embedded in the outer surface of the filter box 703. Activated carbon filter material 705 is placed inside the filter box 703. A door is hinged to the outer surface of the filter box 703 and the activated carbon filter material 705 at corresponding positions.

[0028] In this embodiment, the flue gas generated inside the carbonization cylinder 3 enters the insulation pipe 507 through the air outlet 702 under the negative pressure of the fan 704, and then enters the filter box 703 along the insulation pipe 507. After the flue gas passes through the activated carbon filter material 705 in sequence, the dust and tar are adsorbed. The purified gas passes through the fan 704 and is discharged to the atmosphere. The door can be opened outward to facilitate the regular replacement of the activated carbon filter material 705 and ensure continuous purification effect.

[0029] Example 2

[0030] Based on Example 1, this addresses the issue of the inconvenience in extending the flue gas path, which was present in Example 1.

[0031] like Figure 1-4 As shown, the outer surface of the water tank 8 is provided with a channel 801, and a slide rail 802 is fixedly connected to the outer surface of the channel 801. A first partition 803 is slidably connected inside the slide rail 802, and a second partition 804 is slidably connected inside the slide rail 802. A second valve 4 for controlling the water flow is connected to the upper surface of the water tank 8 by bolts and threads, and a water outlet pipe is connected to the lower surface of the channel 801.

[0032] In this embodiment, both the first partition 803 and the second partition 804 can slide left and right within the slide rail 802. When the two partitions are alternately inserted into the channel 801, an "S"-shaped or multiple-fold flue gas path can be formed within the channel 801, significantly extending the residence time of the flue gas in the water. Similarly, when the first partition 803 and the second partition 804 are on the same side, the flue gas flow is smoothest, making the flue gas path adjustable, which facilitates improving the efficiency of heat absorption in the water tank 8 and realizing the recovery and reuse of some heat. The second valve 4 is used to cooperate with the water pipe to supply water, and the water outlet pipe cooperates with the external valve to discharge hot water from the water tank 8.

[0033] like Figure 1-4 As shown, a support leg 101 for supporting the mounting base 1 is fixedly connected to the lower surface of the mounting base 1, a first valve 201 for controlling the gas passage is connected to the side surface of the burner 2 by bolt thread, a channel pipe 301 is fixedly connected to the upper surface of the carbonization cylinder 3, a connection notch 302 is opened on the upper surface of the carbonization cylinder 3, and a cover 6 is fixedly connected to one end of the heat insulation pipe 507.

[0034] In this embodiment, the support leg 101 lifts the mounting base 1 off the ground, which not only prevents heat from being conducted to the ground, but also leaves enough air intake space at the bottom of the burner 2. The first valve 201 is quickly connected to the external gas pipeline, and the gas flow can be adjusted or cut off by turning it. When the cover 6 is closed by rotating with the insulation pipe 507, the flange at the lower end of the cover 6 is embedded in the connection notch 302 to achieve circumferential positioning.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
