Description

Technical field:

[0001] The present invention relates to the technical field of carbonization processing equipment, and more specifically to a carbonization box. Background technology:

[0002] Carbonization, also known as dry distillation, carbonization, and coking, refers to the reaction process of heating and decomposing solid or organic matter in an air-tight condition or a method of heating solid substances to produce liquid or gas (usually solid) products.

[0003] The existing carbonization of objects, such as wood or bamboo chips, is generally carried out in a carbonization furnace or a carbonization box. In order to achieve the heating effect of the heat preservation box, the existing carbonization furnace or carbonization box has a heat preservation layer component fixed on the inner wall of the box to achieve heat preservation. However, during use, after the carbonization is completed, the furnace body or the box body needs to be cooled down before the material can be taken out. At this time, the only way is to wait for the box body to cool down naturally or blow air to it. Blowing air directly at the box body can easily cause dust in the box body to float, affecting the surrounding environment. In addition, since the heat preservation layer components, such as insulation bricks, have a high temperature and good heat preservation, they cannot be cooled down quickly, thereby affecting the cooling effect.

[0004] Moreover, the existing carbonization furnace or carbonization box is provided with a high-temperature inlet and a high-temperature outlet, and a frame is placed inside for placing materials, but there is no gas guide structure, and the uniform flow of the internal gas cannot be achieved, which affects the carbonization uniformity. Summary of the invention:

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a carbonization box, which has uniform carbonization and high efficiency. The spiral channel formed between the main box and the outer box can be filled with nitrogen and ensure that it has a heat preservation effect when the gas is not flowing. When cooling is required, the external gas flows in the spiral channel and is discharged, which can achieve rapid cooling of the main box and the inner box, thereby allowing the temperature in the inner box to drop rapidly, making it convenient to take out the material.

[0100] In this embodiment, asbestos insulation layers are fixed on the outer wall of the main box body 10 and the outer wall of the pipes and shells of all exposed components to ensure heat insulation and reduce heat loss during operation of the equipment.

[0101] The fans, blowers, etc. used in this embodiment are all high-temperature resistant fans, which can adopt a high-temperature magnetic levitation circulation fan with Chinese patent application number 202410001217.8, which will not be described in detail here.

[0102] When the present embodiment is in use, first, the push rods of all the clamping oil cylinders 33 are pushed so that all the hooks 34 are opened, and the door body 30 can be opened. Then, all the inner material discharging boxes 100 that need to be processed are moved to the left along the guide wheel 1003 on the corresponding guide rail 21, and all the inner material discharging boxes 100 are placed in the inner box body 20. The left side plate of the leftmost inner material discharging box 100 is pressed against the right end surface of the left end plate 11. Then, the door cover 165 is opened, and the transverse connecting shaft 18 is inserted into the corresponding middle through hole. The left end of the transverse connecting shaft 18 extends out of the left end of the corresponding middle through hole. A radially extending edge is formed on the outer side wall of the left end of the transverse connecting shaft 18. The right end surface of the radially extending edge is pressed against the left side wall of the support frame 163. The connecting shaft 18 is inserted into the middle ventilation connecting pipe 1001 corresponding to the middle part of all the inner discharge boxes 100, and its right end extends out of the through hole on the right side plate of the rightmost inner discharge box 100 and the middle through hole of the right baffle 1004 installed on the right side wall of the right side plate of the rightmost inner discharge box 100. Then, the pin 181 is inserted into the two corresponding positioning pin through holes and the radial through hole, and the pressing part formed on the top of the pin 181 presses on the top surface of the guide sleeve 1005. The screw connection part formed in the middle part of the right end face of the horizontal connecting shaft 18 extends out of the right end face of the guide sleeve 1005 and is screwed with two locking nuts pressed against each other, and the left end face of the locking nut on its left side presses against the right end face of the guide sleeve 1005 to achieve fixation;

[0103] Then, after the door body 30 is closed, the push rods of all the pressing cylinders 33 will shrink, causing the hook 34 to flip back to its original position, connecting and fixing the door body 30 and the right door frame 12;

[0104] During operation, high-temperature gas enters the left cover body 16 from the first main air inlet pipe 161, then enters all the middle ventilation connecting pipes 1001, and then is discharged from the corresponding side air outlet holes and ends. The gas discharged from the side air outlet holes is blown onto the materials placed on the middle ventilation connecting pipe 1001 and the air guide pipe 1002, providing heat for heating, drying and carbonizing the materials. Then, part of it is discharged from the flow holes and the top of the inner discharge box 100, and part of it enters from the side air inlet holes of the air guide pipe 1002, and then is discharged from both ends of the air guide pipe 1002, thereby increasing the flow time of the hot air in the inner discharge box 100. Moreover, since the air guide pipe 1002 and the middle ventilation connecting pipe 1001 are staggered, the materials thereon are heated uniformly, thereby improving the uniformity of carbonization and the effect.

[0105] During the heating process, nitrogen is passed through the spiral channel 1, and a control valve (which is a conventional structure and is omitted in the accompanying drawings) is connected to the top of the exhaust pipe 15. When it is closed, the blowing device stops running to ensure that the nitrogen in the spiral channel 1 does not flow. Of course, a control valve can be connected to the air outlet of the blowing device to communicate with the cooling air inlet pipe 14. When not in use, the control valve is closed (the control valve is not installed in this embodiment). When flushing nitrogen, nitrogen is introduced through the top of the exhaust pipe 15 (a connecting pipe on the nitrogen tank is connected to the control valve at the top of the exhaust pipe 15). When introducing nitrogen, the blowing device stops running. After the addition is completed, the control valve at the top of the exhaust pipe 15 is closed and the connected connecting pipe can be pulled out.

[0106] Then, the hot air in the inner box 20 flows back to the lower extension sleeve 131 from the side return air hole of the lower extension sleeve 131, and then flows to the main outlet pipe 13, and the main outlet pipe 13 is connected to the air inlet of the circulation pipeline, and the air outlet of the circulation pipeline is connected to the combustion device, so that the gas is heated again, and the air outlet of the combustion device is connected to the first main air inlet pipe 161, and the heated hot air is passed into the inner box 20 again to provide hot air for it;

[0107] After being heated to a certain temperature, such as 150° (its temperature is sensed by the temperature sensor 3 and the data is transmitted to the control host), the control valves (which are conventional structures and not shown in the drawings) arranged at the main air outlet pipe 13 and the first main air inlet pipe 161 are closed. At the same time, the control valve at the air outlet of the first circulating air outlet pipe 17 is opened, and the control valve at the first circulating air inlet pipe 162 is opened. At the same time, the air inlet pipe (not shown in the drawings) connected to the main air outlet pipe 13 can pass oxygen into the left cover body 16, thereby providing oxygen to the inner box body 20, so that the material inside it is fully burned and carbonized. During the combustion process, the circulating fan 61 is operated, so that the hot air in the inner box body 20 enters the dust collector 60, and after dust removal, it enters the condenser 40. At this time, the cooling water in the condenser 40 does not flow, so the gas is not condensed, and then returns to the inner box body 20 for combustion. When its temperature reaches 450°, oxygen stops being added. , the gas continues to flow, and when the pressure is too high during the heating process or the gas circulation process (when it exceeds 2 kPa, it is sensed by the pressure sensor 4), at this time, it is necessary to open the control valve on the connecting pipe connecting the outlet end of the cooling gas outlet pipe 432 of the condenser 40 and the air inlet connector of the negative pressure tank 50. At the same time, the cooling water in the condenser 40 flows. At this time, after the gas passes through the condenser 40, the gas temperature will be greatly reduced, and the water, grease and other substances in the hot gas will be discharged, and part of the gas discharged from the condenser 40 will enter the negative pressure tank 50 from the cooling gas outlet pipe 432 to achieve storage, thereby reducing the pressure of the inner box 20. When its pressure is less than 2 kPa, the control valve on the connecting pipe connecting the outlet end of the cooling gas outlet pipe 432 and the air inlet connector of the negative pressure tank 50 is closed, and the gas in the negative pressure tank 50 can be discharged to the subsequent gas storage tank through the discharge pipe connected thereto for subsequent use, which will not be described in detail here.

[0108] After running at 450° for a certain period of time, carbon dioxide can be introduced into the air inlet pipe (not shown in the drawings) connected to the main air outlet pipe 13. At the same time, steam is introduced into the steam air inlet pipe 5. The steam first enters the annular pipe 1631, and then is discharged from the multiple steam through holes on the extension pipe 1632 and enters the inner box 20. Together with the carbon dioxide, the material in the inner discharge box 100 is activated. After a certain period of time, the activation is completed, and then the addition of steam and carbon dioxide is stopped.

[0109] Then, the temperature is lowered. When lowering the temperature, the control valve connected to the top of the exhaust pipe 15 is opened, the blowing device is turned on, the external gas is passed into the spiral channel 1, the nitrogen inside is discharged, and the main box body 10 and the inner box body 20 are quickly cooled. At this time, the control valves arranged at the main outlet pipe 13 and the first main inlet pipe 161 are still closed. At the same time, the control valve at the outlet of the first circulation outlet pipe 17 is still opened, the control valve at the first circulation inlet pipe 162 is opened, and the circulation fan 61 is operated, so that the hot air in the inner box body 20 enters the dust collector 60, and after dust removal, enters the condenser 40 for condensation. At this time, the condenser 4 0 is still flowing, thereby continuing to cool the gas and materials in the inner box body 20 until the temperature drops to about 80°, then the door body 30 can be opened, and then the door cover 165 can be opened, the pin 181 can be pulled out, and the two locking nuts can be removed. Then, the transverse connecting shaft 48 can be pulled out to the left from the disassembly through-tube 164 (it is necessary to use a manipulator or a clamp to extend into the disassembly through-tube 164, and its end is screwed to the screwed portion at the left end of the transverse connecting shaft 48, and the transverse connecting shaft 48 can be pulled out by pulling outward). At this time, all the inner discharge boxes 100 can be removed from the inner box body 20. It is easy to operate and has a good use effect.

[0110] In this embodiment, when the condenser 40 is in use, the first heat exchange water outlet connecting pipe 4112 is connected to the water return pipe, and the first heat exchange water inlet connecting pipe 4121 is connected to the cooling water outlet pipe, and the cooling water outlet pipe and the water return pipe are connected to a water-cooled chiller (which is a conventional structure and can be purchased directly, and will not be described in detail here), and the sum of the cross-sectional areas of the inner flow cavities of all inner tube bodies 414 is greater than or equal to the cross-sectional area of ​​the inner flow cavities of the total air outlet connecting pipe head 431 or the total air inlet connecting pipe head 421, and the cross-sectional areas of the inner flow cavities of the total air outlet connecting pipe head 431 and the total air inlet connecting pipe head 421 are equal.

[0111] The hot air from the furnace body enters from the main air inlet connecting pipe head 421, reaches the bottom air inlet shell 420, and then enters all the inner tube bodies 414. The cooling water enters the lower shell 412 from the first heat exchange water inlet connecting pipe 4121, and then enters the outer tube body 413, so that the gas in the inner tube body 414 and the water in the outer tube body 413 exchange heat, thereby cooling the gas. The cooled gas enters the upper air outlet shell 430, and then is discharged from the main air outlet connecting pipe head 431 and enters the inner box body 20.

[0112] The water after heat exchange enters the upper shell 411 and then flows out from the first heat exchange water outlet connecting pipe 4112;

[0113] Some water droplets or oil will be formed in the cooled gas, which will fall along the inner tube body 414 and enter the lower cylindrical body 422 from the lower part of the bottom air inlet shell 420. The liquid level in the lower cylindrical body 422 can be checked by the liquid level gauge 425. When the liquid exceeds the sensing end of the liquid level sensor 426 (the liquid level sensor 426 in this embodiment is a photoelectric liquid level sensor, which uses the principle of reflection and refraction of light at the interface of two different media to achieve sensing), the liquid is sensed by the sensing end of the liquid level sensor 426. When it senses the liquid, the control host receives the signal transmitted by the liquid level sensor 426 and processes it, and then opens the first solenoid valve at the oil outlet pipe 424 until the liquid level sensor 426 is filled. When liquid is sensed, the first solenoid valve at the oil outlet pipe 424 is closed, and then the control host controls the first solenoid valve at the liquid outlet connecting pipe 423 to open, so that water can flow out from the liquid outlet connecting pipe 423. It is usually opened for about 60 seconds, and the first solenoid valve at the liquid outlet connecting pipe 423 can also be manually closed by manually observing the liquid level gauge 425 according to the decrease in the liquid level of the liquid level gauge 425. The oil and part of the water above the water at the sensing end of the liquid level sensor 426 can be discharged from the oil outlet pipe 424 (usually it is oil, and occasionally there will be part of water, but it will not affect the discharge); the rest of the water is discharged from the liquid outlet connecting pipe 423 (a small amount of oil may occasionally be mixed in the liquid outlet connecting pipe 423, but it will not affect the discharge).

[0114] The liquid discharged from the liquid outlet connecting pipe 423 and the oil outlet pipe 424 can be subsequently processed and reused.

[0115] It can automatically discharge the water and oil generated by cooling in real time, reduce accumulation, ensure the normal operation of the equipment, and achieve good use effect.

[0116] When the dust collector 60 of this embodiment is in use, after the hot air enters from the right air inlet connector 63, it is blocked by multiple middle partitions 621 to increase the circulation time in the dust collector 60 (wherein, multiple through holes are formed on the middle partition 621, so as to ensure that the hot air can flow out from the through holes and achieve guidance), and then, after being filtered by the filter screens of all the filter screens 66 with gradually increasing mesh numbers, the dust particles of corresponding sizes can fall into the corresponding dust collection cylinder 65, and the discharge control valve 67 at the bottom thereof is opened, so that the dust can fall into the discharge control valve 67 at the bottom thereof. The storage bag is a conventional structure and will not be described in detail here. Before the dust is discharged from the discharge control valve 67, it passes through the cooling ring assembly 66. One end of the two water-passing connectors of the cooling ring assembly 66 is connected to the water inlet pipe and the other end is connected to the water outlet pipe (the water inlet pipe and the water outlet pipe are connected to a water-cooled chiller, which is a conventional structure and can be directly purchased and will not be described in detail here), so that cooling water passes through the cooling ring assembly 66, and the dust passing through the cooling ring assembly 66 is cooled to ensure that the temperature of the dust entering the storage bag is not high, and the safety is high.

[0117] At the same time, when in use, the timed vibration of the vibration motor 68 can prevent dust accumulation in the dust collection tube 65 and ensure normal material dropping. At the same time, the vibration is transmitted to the dust removal main box 62, and the corresponding filter screen plate 66 can also be vibrated, so that the accumulated dust placed thereon will not fall off, thereby improving the dust removal effect.
