Description

Technical Field

[0001] The invention relates to the technical field of drying, in particular to a drying device used for producing reconstituted wood. Background Art

[0002] Reconstructed wood, also known as regenerated wood or engineered wood, is a kind of artificial wood that is re-modified and reassembled while retaining the basic characteristics of wood. Reconstructed wood has the advantages of high strength, large size and natural wood texture structure. It is widely used in construction, furniture, interior decoration and packaging materials. The production process of reconstructed wood includes peeling and cutting logs into sheets and impregnating with phenolic resin. Because the peeled wood chips usually contain moisture, in order to improve the physical and mechanical properties of the wood chips and reduce the risk of deformation and cracking of the reconstructed wood, the peeled wood chips are dried.

[0003] Existing wood drying equipment, such as Chinese document CN202111549749.8, discloses a comprehensive wood drying device, which enables the device to evenly and comprehensively dry the wood by means of the first motor, heating box, induced draft fan, conveying pipe, heating pipe and air supply pipe and other components. However, when drying wood in the heating box, the moisture on the surface of the wood is easier to evaporate, while the moisture migration rate inside the wood is slower, which will result in the internal moisture not being fully evaporated during drying, resulting in too large a difference in moisture content between the inner and outer layers of the wood, resulting in greater stress inside the wood, which in turn causes deformation of the wood. If the drying temperature and time are increased, the outer layer of the wood may be over-dried.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. The present invention divides the interior of the casing into a low-temperature chamber, a rehumidification chamber, a high-temperature chamber and a cooling chamber by opening and closing door components. The low-temperature chamber can fully evaporate the moisture on the surface of the reconstituted wood log chips.

[0017] 2. The present invention is provided with a heat increasing component. The hot air coming out of the low temperature chamber usually carries dried water vapor. The water vapor reacts with the quicklime bag to release a large amount of heat. The released heat can heat the air and generate higher temperature gas. The high temperature gas flows into the high temperature chamber from the air outlet of the heating box and is finally ejected by the hot air nozzle in the high temperature chamber.

[0018] 3. The present invention is provided with a cooling component. The cooler conveys the coolant to the cooling pipe and starts the induced draft fan at the same time. The induced draft fan draws in air from the external environment. The air is sucked into the interior of the frame from the induced draft port. When flowing through the cooling pipe, the air exchanges heat with the cooling pipe. The coolant in the cooling pipe absorbs the heat in the air, the temperature of the air drops, and cold air is generated. The cold air is then blown into the interior of the cooling chamber from the air outlet. This can effectively avoid the cooling effect being affected by changes in the external environment temperature and ensure the stability and efficiency of the cooling.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0032] A drying device for reconstituted wood production, such as Figure 1-Figure 11As shown, it includes a frame 1 and a casing 2. A conveying component for conveying reconstituted wood log chips is arranged inside the frame 1. The casing 2 is installed on the top surface of the frame 1. A feed port and a discharge port are arranged on the left and right sides of the casing 2 respectively. A humidity detection component for detecting the humidity of the reconstituted wood log chips is arranged at the feed port and the discharge port. An opening and closing door component is arranged inside the casing 2. The opening and closing door component divides the interior of the casing 2 into four processing chambers, which are a low temperature chamber 5, a rehumidification chamber 6, a high temperature chamber 7 and a cooling chamber 8 from left to right. When drying the reconstituted wood log chips, the moisture on the surface of the reconstituted wood log chips is easier to evaporate, while the migration speed of the moisture inside is slower, which will result in that the moisture inside is not fully volatilized during drying, resulting in a large difference in moisture content between the inner and outer layers of the wood. , resulting in greater stress inside the wood, which in turn causes the wood to deform and affects the quality of subsequent reconstituted wood products. To solve this problem, during specific work, the reconstituted wood log chips are placed on the conveying component and enter from the left feed port. The humidity detection component at the feed port will detect the humidity of the reconstituted wood log chips and transmit the data to the external control system. The external control system can adjust the parameters in the low-temperature chamber 5, the rehumidification chamber 6 and the high-temperature chamber 7 according to the humidity of the current reconstituted wood log chips to ensure that each reconstituted wood log chip is in a suitable drying condition. The conveying component drives the reconstituted wood log chips to pass through the low-temperature chamber 5, the rehumidification chamber 6, the high-temperature chamber 7 and the cooling chamber 8 in sequence. Among them, before the reconstituted wood log chips enter the high-temperature treatment, they are first subjected to low-temperature treatment. The reconstituted wood logs are subjected to a low temperature treatment (relatively low temperature) to fully evaporate the moisture on the surface of the reconstituted wood logs, in preparation for the subsequent moisture reconditioning and high temperature treatment. After the low temperature treatment, the reconstituted wood logs are subjected to a moisture reconditioning treatment. The moisture reconditioning treatment can make the moisture distribution on the surface and inside of the reconstituted wood logs more uniform, avoiding problems such as uneven drying, cracks or warping during the subsequent high temperature treatment, thereby improving the quality of the final product. At the same time, moisture reconditioning can reduce the drying stress of the reconstituted wood logs during the high temperature treatment, ensuring the processing quality and stability of the reconstituted wood. After the moisture reconditioning treatment, the reconstituted wood logs are subjected to high temperature drying. High temperature drying can change and remove excess moisture from the reconstituted wood logs, improve the physical and mechanical properties of the reconstituted wood, and enhance the stability of the reconstituted wood. In order to improve the quality and durability of the reconstituted wood logs, after high-temperature treatment, cooling is carried out. The temperature of the reconstituted wood log chips is slowly reduced by the cooling component, so that they are more stable in subsequent processing and use, avoiding thermal stress caused by a sudden drop in temperature. Finally, the humidity detection component at the discharge port detects whether the dried reconstituted wood log chips are qualified. When unqualified is detected, the humidity detection component will transmit the data to the external control system, and then the external control system controls the robot or uses an alarm to remind the operator to take away the unqualified reconstituted wood log chips. Such staged drying treatment can effectively improve the drying effect, reduce the deformation or stress concentration caused by the difference in moisture inside and outside the reconstituted wood log chips during the high-temperature drying process, and improve the overall stability of the reconstituted wood log chips.

[0033] Furthermore, in order to reduce energy consumption, a hot air blower 10 is installed on the top surface of the housing 2, and the hot air blower 10 is connected to the low temperature chamber 5 through a hot air duct and a hot air nozzle. The low temperature chamber 5 is connected to the high temperature chamber 7 through a hot air duct, a heat increasing component and a hot air nozzle. The heat increasing component includes a heat increasing box 1201 fixedly installed on the front and rear sides of the frame 1, and the heat increasing box 1201 is provided with an air inlet 1202 and an air outlet 1203 for ventilation. The air inlet 1202 and the air outlet 1203 are fixedly connected with a filter screen 1 204, a cleaning component for cleaning residues is provided on the filter screen 1204, two movable plates 1205 are slidably connected in the heat increasing box 1201, four quicklime bags are fixed on the opposite surfaces of the two movable plates 1205 by ropes, a box cover is sealedly connected to the top of the heat increasing box 1201, and a drying plate 1206 is fixed at the air outlet 1203. When working, the hot air blower 10 conveys hot air to the low temperature chamber 5 through the hot air duct and the hot air nozzle, and the hot air dried in the low temperature chamber 5 is then passed through the hot air duct and the heat increasing box 1201. The hot air is transported to the high temperature chamber 7, and the dried hot air enters from the air inlet 1202 of the heating box 1201, and then is filtered by the filter 1204 on the air inlet 1202. The filter 1204 on the air inlet 1202 can filter out most of the wood chips and impurities in the hot air. Then the hot air passes through the interior of the heating box 1201. The hot air coming out of the low temperature chamber 5 usually carries the dried water vapor, which reacts with the quicklime bag to release a large amount of heat. The released heat can heat the air. Gas, thereby generating even higher temperature gas, which then flows into the high temperature chamber 7 from the gas outlet 1203 of the heat increasing box 1201, and is finally ejected from the hot air nozzle in the high temperature chamber 7. The filter 1204 at the gas outlet 1203 can prevent part of the quicklime powder from flowing into the hot air nozzle and causing blockage. The drying plate 1206 can absorb the residual water vapor in the high temperature gas and prevent the residual water in the high temperature gas from entering the high temperature chamber 7. In this way, the hot air of the hot air blower 10 is recycled and the energy consumption is reduced.

[0034] Furthermore, in order to remove the residue attached to the filter 1204, the cleaning component includes a rotating rod 1211 rotatably connected to the middle of the filter 1204, and a scraper 1212 is fixedly connected to the rotating rod 1211, wherein the scrapers 1212 are arranged on both sides of the filter 1204 at the air inlet 1202, and the scraper 1212 is arranged on one side of the filter 1204 at the air outlet 1203 located in the heat increasing box 1201, and a fan 1213 is fixedly connected to one end of the rotating rod 1211, and the fan 1213 is fixedly connected to the fan 1213. 13 are all arranged toward the air inlet 1202, and a collecting box 1214 for collecting residues is arranged at the bottom of the heating box 1201. During specific operation, due to the flow of hot air, the fan 1213 is driven to rotate, and the rotation of the fan 1213 drives the rotating rod 1211 to rotate, and the rotating rod 1211 drives the scraper 1212 to rotate, and the scraper 1212 can scrape off the residue adhering to the filter 1204, and the scraped residue will fall into the collecting box 1214 and be collected.

[0035] Furthermore, in order to make the moisture content of the inner and outer surfaces of the reconstituted wood log chips more uniform, an insulating water tank 11 is installed on the top surface of the casing 2, and the insulating water tank 11 is connected to the rehumidification chamber 6 through a water pipe and an atomizing nozzle. Seven guide plates 14 are evenly arranged in the low-temperature chamber 5, and a guide groove 1401 is formed between two adjacent guide plates 14. A water tank 15 is arranged on the front and rear sides of the low-temperature chamber 5, and the water tank 15 is connected to the guide groove 1401. A water pump 16 is installed on the outside of the water tank 15, and both ends of the water pump 16 are respectively connected to the water tank 15 and the insulating water tank 11 through water pipes. The low-temperature chamber 5, the rehumidification chamber 6 and the high-temperature chamber 7 are all provided with ventilation and dehumidification systems (not shown in the figure) to ensure that moisture is removed in time. However, in the low-temperature chamber, if the temperature is low and the humidity is high, water vapor is easily condensed into water droplets. If these water droplets cannot be discharged in time, the subsequent drying efficiency may be affected. During the specific operation, during the drying process, the condensed water droplets flow into the water tank 15 through the guide groove 1401, and then the water in the water tank 15 is transported to the insulation water tank 11 by the water pump 16. The water in the insulation water tank 11 is used to adjust the humidity in the rehumidification chamber 6, wherein the insulation water tank 11 can be connected to an external water source, and then the external control system controls the insulation water tank 11 to heat and adjust the temperature of the water in the insulation water tank 11. Water with a higher temperature evaporates faster, which can more effectively increase the humidity in the rehumidification chamber 6. The water in the insulation water tank 11 flows into the rehumidification chamber 6 through the water pipe and is sprayed out by the atomizing nozzle. After the conveying component conveys the reconstituted wood log chips to the rehumidification chamber 6, the water mist sprayed by the atomizing nozzle will increase the humidity in the rehumidification chamber 6, thereby improving the moisture difference between the inner and outer surfaces of the reconstituted wood log chips, so that the moisture on the inner and outer surfaces of the reconstituted wood log chips is more uniform.

[0036] Furthermore, in order to more accurately measure the humidity of the reconstituted wood log chips, the humidity detection component includes an L-shaped block 401 fixedly connected to the left and right side surfaces of the frame 1, and a screw 402 is threadedly sleeved on the L-shaped block 401. One end of the screw 402 is rotatably connected to a mounting plate 403, and the other end is fixedly connected to a handle. Three humidity sensors 404 for detecting the humidity of the reconstituted wood log chips are installed on the top surface of the mounting plate 403. The humidity sensor 404 is a microwave sensor, which uses the reflection characteristics of microwave signals to check the humidity of an object. During specific operation, the handles on both sides are rotated, and then the handles drive the screw 402 to rotate, thereby adjusting the vertical height of the mounting plate 403, and then adjusting the distance between the humidity sensor 404 and the reconstituted wood log chips, thereby more accurately measuring the humidity of the reconstituted wood log chips.

[0037] Furthermore, in order to avoid the influence of the cooling effect on the temperature change of the external environment and to better cool the reconstituted wood logs, the cooling assembly includes a frame 1301 fixedly connected to the outer walls of the front and rear sides of the cooling chamber 8, a draft fan 1302 and a cooling pipe 1303 are installed in the frame 1301, and a cooler 1304 is installed on the front and rear sides of the frame 1. The cooling pipe 1303 is connected to the cooler 1304 through a pipe. The draft fan 1302 and the cooling pipe 1303 are separated by a water baffle 1305. The water baffle 1305 absorbs moisture in the air to prevent moisture from the outside from being brought into the cooling chamber 8. An air inlet 1307 is provided on one side of the frame 1301, and an air outlet 1308 is provided on the other side. The air inlet 1307 is provided with a A dustproof plate 1306 is provided, which can prevent external dust from entering the cooling chamber 8. During specific operation, the cooler 1304 transports the coolant to the cooling pipe 1303, and at the same time starts the induced draft fan 1302, which inhales air from the external environment. The air is inhaled from the air inlet 1307 into the interior of the frame 1301. When flowing through the cooling pipe 1303, the air will exchange heat with the cooling pipe 1303. The coolant in the cooling pipe 1303 absorbs the heat in the air, and the temperature of the air will drop, thereby generating cold air, which is then blown into the cooling chamber 8 from the air outlet 1308. This can effectively avoid the cooling effect being affected by changes in the external environment temperature, thereby ensuring the stability and efficiency of the cooling.

[0038] Furthermore, in order to ensure that the reconstituted wood log chips can be transported normally, the transport assembly includes five groups of first synchronous belt components 1701 installed inside the frame 1, a flip component 1704 is arranged between two adjacent first synchronous belt components 1701, and the flip component 1704 is located between the front and rear first synchronous belt components 1701, and the flip component 1704 includes a support frame 1705 arranged between two adjacent first synchronous belt components 1701, and the upper part of the support frame 1705 is rotatably connected to a rotating shaft 1706, and both ends of the rotating shaft 1706 are fixedly connected to flip disks 1707, and eight support plates for flipping the reconstituted wood log chips are evenly fixed on the flip disk 1707. Four motors 1708 are installed at the bottom of the frame 1, and the motors 1708 and the pairs of motors 1708 are connected to the flip disks 1707. The corresponding rotating shafts 1706 are connected to each other through the second synchronous belt component 1709, and the first positioning block 1702 and the second positioning block 1703 for limiting the position of the reconstituted wood log pieces are pasted on the synchronous belt of the first synchronous belt component 1701. The opening and closing door assembly includes five lower fixed plates 304 sealed and fixed to the inside of the frame 1, and three upper fixed plates 301 are sealed and fixed to the inside of the casing 2. The inlet and outlet of the casing 2 are both provided with heat insulation curtains 308. The upper fixed plates 301, the lower fixed plates 304 and the heat insulation curtains 308 divide the inside of the frame 1 and the casing 2 into a low temperature chamber 5, a rehumidification chamber 6, a high temperature chamber 7 and a cooling chamber 8. The lower part of the upper fixed plate 301 is slidably connected to the upper movable door 302, and an upper movable door 302 is provided between the upper fixed plate 301 and the upper fixed plate 301. The elastic member 303, the two ends of the upper elastic member 303 are respectively fixed to the upper movable door 302 and the upper fixed plate 301, the lower fixed plate 304 is provided with a slide groove, the lower movable door 306 is slidably connected in the slide groove, a lower elastic member 307 is provided between the lower fixed plate 304 and the lower movable door 306, the two ends of the lower elastic member 307 are respectively fixed to the lower fixed plate 304 and the lower movable door 306, the upper elastic member 303 and the lower elastic member 307 are springs, the first positioning block 1702 is provided with an inclined surface that cooperates with the upper movable door 302 and the lower movable door 306, and the front and rear first positioning blocks 1702 are provided with an extended protrusion on one side away from each other, and the extended protrusion contacts with the second positioning block 1703. The extended protrusion is used to ensure that the reconstituted wood logs can be stably The reconstituted wood log pieces are placed between the first positioning block 1702 and the second positioning block 1703 manually or by a robot, and then the reconstituted wood log pieces are transported by the synchronous belt of the first synchronous belt component 1701 through the low temperature chamber 5, the rehumidification chamber 6, the high temperature chamber 7 and the cooling chamber 8. At the same time, since the four processing chambers are provided with a turning component 1704, the first synchronous belt component 1701 and the turning component 1704 are matched through the setting of the external control program, so that the reconstituted wood log pieces are turned over in the four processing chambers respectively, and then both sides of the reconstituted wood log pieces can be processed. When turning over, the synchronous belt of the first synchronous belt component 1701 transports the reconstituted wood log pieces to the turning position.At the same time, the motor 1708 is started, and then the motor 1708 drives the rotating shaft 1706 to rotate through the second synchronous belt component 1709, and then the rotating shaft 1706 drives the flip disk 1707 to rotate, and then the support plate on the flip disk 1707 lifts the reconstructed wood log piece and rotates it 180 degrees, and then the reconstructed wood log piece is rotated by the flip disk 1707 to between the first positioning block 1702 and the second positioning block 1703 of another first synchronous belt component 1701. Through external program control, the continuous coordination of the first synchronous belt component 1701 and the flip component 1704 can be achieved, and then the continuous flipping of the reconstructed wood log piece can be achieved. Transportation, it should be noted that when the pallet lifts the reconstructed wood log piece and rotates it to more than 90 degrees, the reconstructed wood log piece will slide between two adjacent pallets and slide from a high place to a low place. At this time, the front and rear distance of the reconstructed wood log piece may move slightly, and a certain distance is set between the extended protrusion of the first positioning block 1702 and the first synchronous belt component 1701. This distance can prevent the extended protrusion from causing obstruction when the flipping component 1704 flips. It should also be noted that the materials used for the synchronous belts of the first synchronous belt component 1701 and the second synchronous belt component 1709 are both high-temperature resistant materials, such as silicone. ,

[0039] When replacing the processing chamber, the first positioning block 1702 squeezes the upper movable door 302, so that the upper movable door 302 moves upward, and then the upper movable door 302 can be opened, and then the upper movable door 302 squeezes the upper elastic member 303, so that the upper elastic member 303 is deformed. Since an extended protrusion is provided at one end of the first positioning block 1702, it can ensure that the reconstituted wood log pieces can completely replace the processing chamber. When the second positioning block 1703 replaces the processing chamber, the upper elastic member 303 is reset, and then the upper movable door 302 is reset. In this way, during transportation, the interference between the two adjacent processing chambers is reduced, ensuring that the processing effect of each processing chamber is not affected. The technical principles and effects of the lower movable door 306 and the upper movable door 302 are consistent, so they are not elaborated.
