Description

TECHNICAL FIELD

[0001] The present application relates to the field of wood processing, in particular to the field of wood drying and carbonization. BACKGROUND

[0002] Wood drying and carbonization is a homogeneous carbonization process of wood under high temperature without any chemical agent. There are many factors affecting the strength of carbonized wood, such as the water content in the carbonization environment during the carbonization process.

[0003] According to the search, the patent for invention with publication number CN101214675B discloses a wood hot-pressing carbonization strengthening method, which dries, planes, hot-presses, cools and finishes the wood in sequence to obtain the expected carbonized wood. However, it has the following shortcomings: during the wood carbonization process, the water vapor content in the carbonization environment is one of the important factors affecting the carbonization quality. Specifically, the water in the wood is evaporated to form water vapor, which increases the water content in the carbonization environment. If not removed in time, it may cause the wood to crack and deform during the carbonization process, resulting in low wood strength. This is the reason why the water content needs to be controlled in the drying kiln according to the density of the wood during the drying process, which further demonstrates that the water content is one of the important factors affecting the strength of carbonized wood. Therefore, accurate control of the water content, which is an influencing factor, can positively affect the final carbonization quality and improve the mechanical properties such as the strength of carbonized wood.

[0004] Based on the above, according to the search, the patent for invention with publication number CN109397450B discloses a wood carbonization device. During the water vapor flow, the high-temperature water absorption block absorbs water vapor, and the connecting suction block sucks the liquid in the high-temperature water absorption block into the water storage tank. Although it can realize the absorption of water during the wood drying and carbonization process, and ensure that the water content in the carbonization environment is within the preset range, it still has some shortcomings: it only passively captures water in the water vapor flow path and cannot timely process according to the real-time data of the water content in the carbonization environment. On the one hand, it may cause the wood to be carbonized in a humidity environment exceeding the preset range, resulting in low strength of the carbonized wood. On the other hand, it may cause uneven distribution of water in the carbonization environment, which may also cause low strength of the carbonized wood. In addition, the wood cannot be evenly dried and carbonized, which needs to be improved.

[0040] REFERENCE Figures 1-9 An integrated device for wood drying and carbonization includes a carbonization tank 100, a supporting frame 200, and an air supply mechanism 300, wherein:

[0041] The carbonization tank 100 is horizontally arranged in a horizontal position, and each of the two openings is provided with a tank cover 101, which is driven to open or close by an opening and closing member 105.

[0042] The supporting frame 200 is used for carrying the wood to be carbonized, and is pulled by the pulling member 500 to enter or leave the carbonization tank 100, and is driven to rotate by the driving member 400 after entering the carbonization tank 100;

[0043] The gas supply mechanism 300 is used for supplying dry hot gas to the carbonization tank 100, and further, the outer circumferential surface of the carbonization tank 100 is provided with a linear hole 102 at the lowest point along the axial direction, the linear hole 102 is provided with an air inlet pipe 103 at the hole opening, the air inlet pipe 103 and the gas supply mechanism 300 are communicated through a connecting pipe 104, and the outer circumferential surface of the carbonization tank 100 is provided with an air outlet pipe 106 at the highest point.

[0044] I. Opening or closing of the tank cover 101:

[0045] Referring to Figure 7 With Figure 9 , the outer surface of the tank cover 101 extends an L-shaped rod 1011, and the outer surface of the carbonization tank 100 is provided with a protruding bracket.

[0046] The opening and closing member 105 includes a threaded shaft 1053 installed on the protruding bracket, the threaded shaft 1053 is parallel to the carbonization tank 100, the threaded shaft 1053 is provided with two and the two threaded shafts 1053 are engaged with a worm gear 1055, it should be noted here that the teeth on the worm are wrapped around the worm shaft like threads, so the threaded shaft 1053 can engage with the worm gear 1055.

[0047] The worm gear shaft of the worm gear 1055 is connected with the L-shaped rod 1011.

[0048] In addition, the worm gear 1055 is installed on the bracket body 1054, and the bracket body 1054 and the protruding bracket form a sliding fit along the axial direction of the threaded shaft 1053.

[0049] Since the two tank covers 101 are provided, the two opening and closing members 105 are provided, so as to reduce the cost of the power source, two motors two 1051 can be provided on the brackets, the output end of each motor two 1051 is connected with a transmission shaft 1052, and the two ends of the transmission shaft 1052 are connected with the threaded shafts 1053 of the two opening and closing members 105. The two motors two 1051 can drive the two threaded shafts 1053 to rotate, the rotation direction of the threaded shaft 1053 is positive when the worm gear 1055 rotates forward, and the rotation direction of the threaded shaft 1053 is reverse when the worm gear 1055 rotates reversely. When the two threaded shafts 1053 rotate at the same speed, the worm gear 1055 rotates and drives the L-shaped rod 1011 and the tank cover 101 to rotate. When one of the two threaded shafts 1053 rotates forward and the other rotates reversely at the same speed, the meshing relationship between the worm gear 1055 and the threaded shaft 1053 is locked, the worm gear 1055 can only move along the axis of the threaded shaft 1053, and the L-shaped rod 1011 and the tank cover 101 move together. In addition, when one of the two threaded shafts 1053 rotates forward and the other rotates reversely at different speeds, the worm gear 1055 rotates and moves, and the tank cover 101 rotates and moves. Based on these actions, the tank cover 101 can be coaxial with the carbonization tank 100, then the tank cover 101 retreats to close the opening of the carbonization tank 100, or the tank cover 101 advances to open the opening of the carbonization tank 100, and then moves away from the opening of the carbonization tank 100. Such closing or opening action can better seal the opening of the carbonization tank 100.

[0050] II. The supporting frame 200 bears wood:

[0051] Referring to Figure 1 With Figure 3 , the supporting frame 200 is split type, including a main frame 201 and a sub-frame 202, which are detachably connected, for example, by bolts and screws, and can together form a rectangular frame that bears wood and has a circular frame at both ends. The outer ring surface of the circular frame is provided with a plurality of balls 205. When the supporting frame 200 is located in the carbonization tank 100, the balls 205 are in contact with the tank wall of the carbonization tank 100, the circular frame is coaxial with the carbonization tank 100, and the balls 205 are arranged in an array. In addition, the sub-frame 202 is installed on the upper end of the main frame 201, i.e. the upper end of the main frame 201 is open, for placing wood, and then the sub-frame 202 is installed on the main frame 201, so as to limit the movement of the wood.

[0052] The main frame 201 is provided with a main gear ring 203, and the sub-frame 202 is provided with a sub-gear ring 204. When the main frame 201 and the sub-frame 202 are connected, the main gear ring 203 and the sub-gear ring 204 together form a complete gear ring.

[0053] III. Movement of the supporting frame 200:

[0054] Referring to Figure 3 The circular frame of the supporting frame 200 is provided with slots 206.

[0055] Referring to Figure 4 With Figure 5 The push-pull member 500 comprises a support rail 507, the upper end of which is provided with an arc slot parallel to the axis of the carbonization pot 100, and the ball 205 arranged at the lowest point of the outer circular surface of the supporting frame 200 is located in the arc slot to support and guide the movement of the supporting frame 200.

[0056] The push-pull member 500 further comprises a push-pull frame 502 and a linear module I 501 for driving the push-pull frame 502 to move along the axis of the carbonization pot 100.

[0057] The push-pull frame 502 is provided with two sets of oppositely arranged plug-in components, further, the plug-in components comprise a plug-in plate 504 slidingly installed on the push-pull frame 502 in a horizontal direction perpendicular to the axis of the carbonization pot 100 and a linear module II 503 for driving the plug-in plate 504 to move, the opposite sides of the plug-in plate 504 in the two sets of plug-in components are provided with a plug pin, the plug pin comprises two vertical plug pins 505 arranged vertically and two horizontal plug pins 506 located between the two vertical plug pins 505, and the slots 206 are correspondingly matched in shape with the plug pin and are provided with two.

[0058] Initially, the supporting frame 200 is supported from the bottom by the support rail 507, and the two plug pins are respectively located in the two slots 206 to fix the supporting frame 200, after the wood is placed and the supporting frame 200 is assembled, the push-pull frame 502 is driven to move by the linear module I 501 to send the supporting frame 200 into the carbonization pot 100, the rotational fit between the supporting frame 200 and the carbonization pot 100 is completed by the ball 205, then the plug pin is driven to disengage from the slot 206 by the linear module II 503, the push-pull frame 502 is driven to retreat by the linear module I 501, and finally the pot cover 101 is closed;

[0059] Conversely, the pot cover 101 is opened, the plug pin is inserted into the slot 206 by the cooperation of the linear module I 501 and the linear module II 503, and then the supporting frame 200 can be pulled out of the carbonization pot 100 by the linear module I 501.

[0060] IV. Rotation of the supporting frame 200 in the carbonization pot 100:

[0061] Referring to Figure 7 With Figure 8, the outer surface of the carbonization tank 100 is provided with a notch, the driving member 400 comprises a gear 402 parallel to the carbonization tank 100 and a motor 401 for driving the gear 402 to rotate, the gear 402 partially extends into the carbonization tank 100, when the supporting frame 200 enters the carbonization tank 100, the gear 402 is engaged with the gear ring on the supporting frame 200, then the supporting frame 200 can be driven to rotate by the motor 401, further, a sealing element is matched and installed at the notch, preferably, the teeth of the gear 402 are chamfered at two edges along the circumferential direction of the index circle, which is meaningful that the supporting frame 200 may be affected to enter the carbonization tank 100 due to the misalignment of the teeth on the gear 402 and the teeth on the gear ring, therefore, the chamfering can make the supporting frame 200 enter the carbonization tank 100 smoothly and the gear 402 is engaged with the gear ring.

[0062] The working process of the embodiment one is as follows:

[0063] Firstly, the supporting frame 200 is fixed by the supporting rail 507 and the plug-in part, then wood is put into the supporting frame 200, after the wood is placed and the supporting frame 200 is assembled, the linear module 501 drives the push-pull frame 502 to move, the supporting frame 200 is sent into the carbonization tank 100, the rotating fit between the supporting frame 200 and the carbonization tank 100 is completed by the ball 205, then the linear module 503 drives the plug to separate from the slot 206, the linear module 501 drives the push-pull frame 502 to retreat, finally the opening and closing member 105 closes the tank cover 101, and the preparation work is completed.

[0064] Then, the dry hot gas provided by the gas supply mechanism 300 enters the carbonization tank 100 through the connecting pipe 104, the gas inlet pipe 103 and the wire hole 102, and is discharged through the gas outlet pipe 106, at the same time, the supporting frame 200 is driven to rotate at a low speed by the motor 401, and the wood on the supporting frame 200 can be more uniformly and fully contacted with the hot gas, and the drying and carbonization effect is better.

[0065] During the drying and carbonization process of the wood, the humidity of the drying environment can be monitored in real time by the humidity sensor embedded in the carbonization tank 100, if the humidity exceeds the preset range, the motor 401 can be driven to drive the supporting frame 200 to rotate at a high speed, since the supporting frame 200 is loaded with wood boards, when rotating at a high speed, it is equivalent to a fan blade, which can actively drag the air in the carbonization tank 100 to move into the gas outlet pipe 106, and the water vapor will be discharged together, that is, the water vapor can be actively dragged out of the carbonization tank 100, the humidity in the carbonization tank 100 is timely restored to the preset range, the strength of the carbonized wood is ensured, and the carbonization tank 100 can also be air-stirred, so that the moisture in the carbonization tank 100 is more evenly distributed, which can also improve the strength of the carbonized wood.

[0066] In the above process, the air discharged through the air outlet pipe 106 still has residual heat, so a drying structure can be arranged between the air outlet pipe 106 and the air supply mechanism 300 to dry the air, which is then returned to the air supply mechanism 300 for heating, thereby greatly reducing the energy consumption of the air supply mechanism 300. The drying structure can be realized by existing drying technologies, such as desiccant, activated carbon, etc., which will not be described in detail. Embodiments

[0067] With reference to Figures 10-14 , the air supply mechanism 300 includes a fan 301 and a heat exchange component 303. The air inlet end of the fan 301 is used to receive dry air. The drying technology of the air is realized by existing technology, which will not be described in detail. The air outlet end of the fan 301 and the air inlet end of the heat exchange component 303 are connected by air pipe one 302. The air outlet end of the heat exchange component 303 and the connecting pipe 104 are connected by air pipe two 304.

[0068] With reference to Figure 12 , the heat exchange component 303 includes an outer support 3031 and a heat exchange pipe installed on the outer support 3031 by an elastic connecting piece 3033. Further, the outer surface of the heat exchange pipe is provided with a lug. The elastic connecting piece 3033 includes a connecting shaft connected with the lug and a hollow shaft connected with the outer support 3031. The hollow shaft is coaxially located outside the connecting shaft. The connecting shaft is parallel to the heat exchange pipe. A plurality of elastic metal sheets are arranged between the hollow shaft and the connecting shaft. The outer portion of the heat exchange pipe is provided with a vibrator 305. The heat exchange pipe can be driven to vibrate by the vibrator 305. The two ends of the heat exchange pipe are respectively connected with the air pipe one 302 and the air pipe two 304.

[0069] With reference to Figure 12 and Figure 13 , the heat exchange pipe includes an outer pipe 3032 connected with the elastic connecting piece 3033, a core pipe 3035 coaxially located inside the outer pipe 3032, and an intermediate pipe 3037 coaxially located between the outer pipe 3032 and the core pipe 3035. The intermediate pipe 3037 and the outer pipe 3032 are connected by a fin 3034. A heating element 3038 is arranged between the intermediate pipe 3037 and the core pipe 3035. The heating element 3038 can adopt existing electric heating technology or existing high-frequency heating technology. A heat insulation sleeve 3039 is arranged between the heating element 3038 and the intermediate pipe 3037. The end portion of the intermediate pipe 3037 extends an embedded step, which is connected with the core pipe 3035.

[0070] Preferably, a core shaft 3036 is coaxially arranged in the core pipe 3035. The core shaft 3036 is thick in the middle and thin at both ends.

[0071] Preferably, with reference to Figure 14The heat exchange pipe is provided with two groups of fins 3034 arranged in a staggered manner.

[0072] The working process of the second embodiment is as follows:

[0073] The fan 301 runs to pull dry air to enter the carbonization tank 100 through the air pipe one 302, the heat exchange pipe, the air pipe two 304, the connecting pipe 104, the air inlet pipe 103 and the wire hole 102 in sequence.

[0074] The heat exchange process is as follows: the heating element 3038 runs to make the core shaft 3036, the core pipe 3035, the intermediate pipe 3037 and the fins 3034 made of heat-conducting materials in a high-temperature state. At the same time, when the air passes through the heat exchange pipe, part of the air passes through the core pipe 3035 and tightly adheres to the core shaft 3036 based on the Bernoulli principle, so that the heat exchange efficiency is higher. Another part of the air passes through the area where the fins 3034 are located. Since the fins 3034 in the two heat exchange pipes are arranged in a staggered manner, the air collides with the fins 3034 in the other heat exchange pipe after passing through one heat exchange pipe and is scattered. In this way, the heat exchange efficiency between the fins 3034 and the air can be improved. At the same time, the existence of the vibrator 305 can drive the fins 3034 to actively hit the air, so that the heat exchange efficiency between the fins 3034 and the air is further improved. In summary, the heat exchange efficiency of the heat exchange component 303 is higher, the heating effect is better, and the energy consumption is lower.

[0075] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, without departing from the technical solution of the present application. Any modification, change, equivalent change and modification of the above embodiments based on the technical essence of the present application are still within the scope of the present application.
