Description

Technical Field

[0001] This invention relates to the field of wood treatment technology, specifically to an environmentally friendly wood heat treatment device with a rotating heating mechanism. Background Technology

[0002] As a renewable resource, wood has inherent defects such as easy deformation, easy decay, and dimensional instability. In the wood processing industry, heat treatment is the core physical modification method to improve the performance of wood. Through pyrolysis treatment under specific temperature, humidity and gas environment, the dimensional stability, decay resistance and insect resistance of wood can be significantly enhanced, the hygroscopicity and expansion rate and the moisture content of wood can be reduced, and the wood can be given a natural warm color. This provides high-quality materials for furniture manufacturing, building decoration, landscaping and other fields, thereby expanding the application scenarios of wood. The wood heat treatment process will generate a large amount of waste gas (such as volatile organic compounds), dust (wood fiber debris) and condensation water droplets after water evaporates.

[0003] Existing wood heat treatment equipment mostly uses a fixed clamping method, keeping the wood stationary inside the treatment chamber. The heating source is usually fixedly installed on one side or in a localized area of ​​the chamber. This can easily lead to excessively high temperatures in the parts of the wood near the heating source, while the parts farther away from the heating source are not heated sufficiently, resulting in a significant temperature gradient. This, in turn, causes inconsistent moisture content and uneven deformation in different parts of the wood, ultimately affecting the stability of product quality and even leading to problems such as cracking and warping, rendering the wood unusable. At the same time, the exhaust gas and dust generated during the wood heat treatment process are mostly directly emitted into the air, polluting the ecological environment and endangering the health of the operators. Condensed water droplets adhere to the top of the inner wall of the treatment chamber. If they drip onto the surface of the wood being heated, they can disrupt the heat treatment process, causing abnormal local moisture content and further affecting product quality.

[0004] Based on this, the present invention designs an environmentally friendly wood heat treatment device with a flipping and heat equalization mechanism to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an environmentally friendly wood heat treatment device with a flipping and heat equalization mechanism, to solve the problems mentioned in the background art. Existing wood heat treatment devices often use a fixed clamping method, keeping the wood stationary inside the treatment chamber. The heating source is usually fixedly installed on one side or in a localized area of ​​the chamber, which easily leads to excessively high temperatures in parts of the wood near the heating source and insufficient heating in parts far from the heating source, resulting in significant temperature gradients. This causes inconsistent moisture content and uneven deformation in different parts of the wood, ultimately affecting product quality stability and even leading to problems such as cracking and warping, rendering the wood unusable. Furthermore, the waste gas and dust generated during wood heat treatment are often directly emitted into the air, polluting the ecological environment and harming the health of operators. Condensed water droplets adhering to the top of the inner wall of the treatment chamber, if dripping onto the surface of the heated wood, can disrupt the heat treatment process, causing abnormal local moisture content and further affecting product quality.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up an intermittent turntable, cylindrical pins, limiting turntables, movable clamping blocks, connecting slide bars, movable frames, a dual-output shaft motor, and a linkage bar, controls the synchronous extension and retraction of electric push rods inside two relatively limiting turntables, pushing the movable frames to slide, causing the linkage sliders to slide in the middle of the connecting slide bars and at both ends of the movable frames, driving the connecting slide bars to slide on both sides of the limiting turntables, and pushing the movable clamping blocks to slide inside the movable slide grooves, until the four movable clamping blocks approach the four corners of the wood for clamping and fixing. When the wood is fixed inside the processing box for heating and baking, the dual-output shaft motor is started to drive the drive turntable to rotate, causing the linkage bar to drive the three dials on the same side to rotate synchronously, controlling the cylindrical pins to intermittently engage with the intermittent slots, pushing the intermittent turntables to drive the rotating clamping mechanism to rotate intermittently, causing the wood clamped and fixed between the two limiting turntables to rotate intermittently, so that the surface of the wood intermittently aligns with the swing heating mechanism, realizing the uniform turning of the wood during the heat treatment process, ensuring that all parts of the wood are in full contact with the heating source, improving the uniformity of heating, and ensuring the stability of product quality; 2. This invention, by incorporating a reciprocating screw, a movable seat, a cleaning scraper, a lifting spring, an exhaust fan, an air filter box, and a rotating clamping plate, addresses the issue of pollutants such as exhaust gas, wastewater, and dust generated during heat treatment of wood within the processing chamber. The air filter box is inserted into the top of the exhaust hood, and the rotating clamping plate engages with the fixing hook, thus securing the air filter box to the top of the exhaust hood. Activating the exhaust fan draws air from inside the processing chamber, causing the air to carry the exhaust gas and dust through the air filter box, where the pollutants are filtered out. After adsorption and purification, the wastewater is discharged. At the same time, the wastewater generated during heat treatment evaporates and condenses into water droplets at the top of the treatment tank. The drive motor is started to drive the reciprocating screw to rotate, causing the moving seat to move the collection box back and forth on the surface of the two limit slide rods. Under the rebound action of the lifting spring, the first bevel gear is lifted, so that the cleaning scraper sticks to the top of the treatment tank to scrape off the water droplets. The water droplets are scraped off and concentrated inside the collection box for treatment, realizing the synergistic purification of pollutants such as waste gas, wastewater, and dust generated during heat treatment, protecting the ecological environment and human health.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-10 The present invention provides a technical solution:

[0031] An environmentally friendly wood heat treatment device with a flipping and heat equalization mechanism includes a treatment box 1. A sliding door panel 2 is symmetrically slidably installed on one side of the treatment box 1. A swing heating mechanism 3 is symmetrically fixedly installed on the inner wall of the treatment box 1 away from the sliding door panel 2. Three intermittent rotation mechanisms 4 are rotatably installed on both sides of the treatment box 1 via bearings. Three rotation clamping mechanisms 5 are respectively provided on both sides of the inner wall of the treatment box 1, and the positions of the rotation clamping mechanisms 5 and the intermittent rotation mechanisms 4 are corresponding. A drive mechanism 6 is fixedly connected to the top of the treatment box 1, and a cleaning mechanism 7 is provided on the top of the inner wall of the treatment box 1. An exhaust hood 8 is fixedly connected to the bottom of the side of the treatment box 1 away from the sliding door panel 2. An exhaust fan 9 is fixedly connected to the top of one side of the exhaust hood 8. An air filter box 10 is slidably inserted into the top of the exhaust hood 8. Fixing buckles 11 are fixedly connected to the top of both sides of the exhaust hood 8.

[0032] During operation, insert the air filter box 10 into the top of the exhaust hood 8, and secure it to the top of the exhaust hood 8 with the fixing buckle 11. Slide open the two sliding door panels 2, lift the wood and clamp it between the two opposing rotating clamping mechanisms 5, and push to close the two sliding door panels 2. Start the swing heating mechanism 3 to bake and heat one side of the wood. Start the drive mechanism 6 to drive the intermittent rotation mechanism 4 to rotate, and control the rotating clamping mechanism 5 to drive the wood to rotate intermittently inside the processing box 1, so that the surface of the wood intermittently faces the swing heating mechanism 3, ensuring that all surfaces of the wood are in full contact with the swing heating mechanism 3 for uniform heating. At the same time, start the exhaust fan 9 to draw the exhaust gas and dust generated during wood processing inside the processing box 1 out of the exhaust hood 8. The exhaust gas and dust are filtered by the air filter box 10 and clean air is discharged from the processing box 1. The top of the treatment chamber 1, away from the sliding door panel 2, is equipped with a vent. When the air containing exhaust gas and dust is extracted from the treatment chamber 1, outside air is introduced into the treatment chamber 1 through the vent to ensure the balance of air pressure inside the treatment chamber 1. The hot air generated during baking, along with the water vapor evaporated from the wood, floats up and condenses into water droplets on the top of the treatment chamber 1. The cleaning mechanism 7 scrapes and cleans the water droplets condensed on the top of the treatment chamber 1 to prevent water droplets from dripping onto the surface of the wood and affecting the heat treatment effect of the wood.

[0033] As a further embodiment of the present invention, the intermittent rotation mechanism 4 includes an intermittent turntable 401, which is rotatably connected to the processing box 1 via bearings. The outer circular surface of the intermittent turntable 401 is provided with four intermittent slots 402 at equal angles. An arc-shaped groove 403 is provided between two adjacent intermittent slots 402 on the outer circular surface of the intermittent turntable 401. A mounting turntable 404 is provided on one side of the intermittent turntable 401, which is rotatably connected to the processing box 1 via bearings. A dial 405 is fixedly connected to one side of the mounting turntable 404. The dial 405 is a semi-circular arc disc, and the arc surface of the dial 405 fits tightly against the arc-shaped groove 403. A cylindrical pin 406 is fixedly connected to the edge of the mounting turntable 404 on one side of the dial 405, and the cylindrical pin 406 is engaged with the intermittent slots 402.

[0034] During operation, the rotating installation turntable 404 drives the dial 405 to rotate close to the arc-shaped slide groove 403, causing the cylindrical pin 406 to rotate intermittently and engage with the corresponding intermittent slot 402. This pushes the intermittent turntable 401 to rotate intermittently, causing the intermittent turntable 401 to drive the rotating clamping mechanism 5 to rotate intermittently inside the processing box 1. This causes the wood surface, which is clamped and fixed between the two rotating clamping mechanisms 5, to intermittently face the swing heating mechanism 3, making the wood rotate evenly inside the processing box 1 and ensuring that all sides of the wood are intermittently facing the swing heating mechanism 3 for even heating and baking.

[0035] As a further embodiment of the present invention, the rotating clamping mechanism 5 includes a limiting turntable 501, and the limiting turntable 501 is coaxially and fixedly connected to the intermittent turntable 401. Four movable grooves 502 are provided at equal angles on one side of the limiting turntable 501. A movable clamping block 503 is slidably connected through the interior of each movable groove 502. A connecting slide bar 504 is slidably connected between two movable clamping blocks 503 on the same side. The connecting slide bar 504 has sliding through grooves at both ends, and the connecting slide bar 504 controls the movable clamping block when sliding. Block 503 slides synchronously within the corresponding movable slide groove 502, thereby controlling the synchronous movement of the movable clamping blocks 503 at both ends of the connecting slide bar 504, so that the four movable clamping blocks 503 slide and unfold synchronously, thereby clamping and fixing the two ends of the square wood, and the movable clamping blocks 503 slide at both ends of the connecting slide bar 504; an electric push rod 505 is fixedly connected to the center position of one side of the limiting turntable 501. The electric push rod 505 consists of a rectangular sleeve and a telescopic block. One end of the telescopic block is connected to the movable frame 506. The fixed connection allows the movable frame 506 to slide when the telescopic block extends or retracts into the sleeve. The telescopic end of the electric push rod 505 is fixedly connected to the movable frame 506, which has a symmetrical C-shaped layout. A straight rod in the middle connects to the lugs at both ends, and each lug has a through groove. The movable frame 506 slides against the connecting slide bar 504 at both ends, and a linkage slider 507 is slidably connected at the overlapping positions of the movable frame 506 and the connecting slide bar 504. One side of the linkage slider 507... The connecting slide bar 504 is slidably connected to the connecting slide bar 504. A through groove is provided through the center of the connecting slide bar 504. Through grooves are provided at both ends of the moving frame 506. The linkage slider 507 is slidably connected inside the through groove. At the same time, one end of the linkage slider 507 extends through the through groove to the through grooves at both ends of the moving frame 506. When the moving frame 506 slides, the overlapping position of the through grooves of the moving frame 506 and the connecting slide bar 504 changes, pushing the linkage slider 507 to slide in the through grooves of the moving frame 506 and the connecting slide bar 504.

[0036] During operation, the electric push rod 505 is extended and retracted to push the movable frame 506 to slide inside the limiting turntable 501, so that the two ends of the movable frame 506 slide close to the connecting slide bar 504 on one side, which drives the linkage slider 507 to slide in the center of the connecting slide bar 504. The connecting slide bar 504 slides along the slide groove at both ends of the movable frame 506, pushing the connecting slide bar 504 to slide to both sides, which drives the movable clamping block 503 to slide inside the movable slide groove 502 until the four movable clamping blocks 503 are close to the four corners of the wood, clamping and fixing the wood between the two limiting turntables 501, which is convenient for clamping and fixing the wood or releasing and removing it.

[0037] As a further embodiment of the present invention, the drive mechanism 6 includes a dual-output shaft motor 601. Rotating columns 602 are fixedly connected to the output ends on both sides of the dual-output shaft motor 601. A support plate 603 is symmetrically rotatably connected to the surface of the rotating column 602 through bearings. The support plate 603 is fixedly connected to the top of the processing box 1. A drive turntable 604 is fixedly connected to one end of the rotating column 602. A linkage bar 605 is rotatably connected to the edge of the drive turntable 604 through a rotating shaft. The linkage bar 605 is rotatably connected to the edge of the dial 405 through the rotating shaft.

[0038] During operation, the dual-output shaft motor 601 is started to drive the two rotating columns 602 to rotate synchronously, causing the two drive turntables 604 to rotate synchronously, which in turn drives the linkage bar 605 to reciprocate. Under the action of the rotating shaft connection between the linkage bar 605 and the edge of the dial 405, the three dials 405 on the same side are driven to rotate synchronously, controlling the three sets of intermittent turntables 401 to rotate intermittently synchronously.

[0039] As a further embodiment of the present invention, the cleaning mechanism 7 includes a reciprocating screw 701, and both ends of the reciprocating screw 701 are rotatably connected to the top of the inner wall of the processing box 1 through bearings. One end of the reciprocating screw 701 is fixedly connected to a bevel gear 702 through the processing box 1. A drive motor 703 is fixedly connected to the bottom of one side of the processing box 1. A bevel gear 704 is fixedly connected to the output end of the drive motor 703, and the bevel gear 704 meshes with the bevel gear 702. Limiting slide rods 705 are symmetrically fixedly connected to the top of the inner wall of the processing box 1 on both sides of the reciprocating screw 701. A movable seat 706 is threaded through the surface of the reciprocating screw 701, and both sides of the movable seat 706 are slidably connected to the surface of the limiting slide rod 705.

[0040] During operation, the drive motor 703 is started to drive the second bevel gear 704 to rotate. Under the meshing action of the second bevel gear 704 and the first bevel gear 702, the reciprocating screw 701 is driven to rotate on the inner wall of the processing box 1, so that the moving seat 706 moves back and forth on the surface of the reciprocating screw 701. When the moving seat 706 slides on the surface of the limiting slide bar 705, the moving seat 706 is limited to ensure that the moving seat 706 will not tilt or deflect during the sliding process.

[0041] As a further embodiment of the present invention, the top of the movable seat 706 is symmetrically provided with limiting slots 707, and a collection box 708 is slidably inserted into the top of the movable seat 706. Limiting inserts 709 are fixedly connected to the bottom of both sides of the collection box 708, and the limiting inserts 709 are correspondingly inserted into the limiting slots 707. An elastic pad 710 is fixedly connected to one side of the bottom of the collection box 708. Mounting brackets 711 are fixedly connected to both sides of the inner wall of the collection box 708, and a top plate 712 is slidably connected through the surface of the mounting bracket 711. A cleaning scraper 713 is fixedly connected between the two top plates 712, and the cleaning scraper 713 is slidably connected to the top of the processing box 1. A lifting spring 714 is sleeved on the surface of the mounting bracket 711 at the bottom of the top plate 712.

[0042] During operation, the collection box 708 is tightly inserted into the top of the movable seat 706, so that the limiting strip 709 is inserted into the corresponding limiting slot 707 until the elastic pad 710 is tightly pressed against the top of the movable seat 706, fixing the collection box 708 to the top of the movable seat 706. Under the rebound action of the lifting spring 714, the top plate 712 is lifted, so that the cleaning scraper 713 is pressed against the top of the processing box 1. When the movable seat 706 rotates with the reciprocating screw 701, it drives the cleaning scraper 713 to move back and forth in the top of the processing box 1, scraping away the water droplets condensed in the top of the processing box 1. The scraped water droplets fall into the collection box 708 for collection and treatment.

[0043] As a further embodiment of the present invention, positioning slots 801 are respectively provided through both sides of the exhaust hood 8, and positioning blocks 1001 are respectively fixedly connected to both sides of the air filter box 10, and the positioning blocks 1001 are correspondingly inserted into the positioning slots 801. A fixing hook 1002 is fixedly connected to the bottom of one side of the positioning block 1001. The fixing buckle 11 includes a mounting base 1101, and the mounting base 1101 is fixedly connected to the top of both sides of the exhaust hood 8. The top of the mounting base 1101 is rotatably connected to a rotating plate 1102 through a pin, and the top of the rotating plate 1102 is engaged with the fixing hook 1002. Positioning blocks 1103 are symmetrically fixedly connected to the bottom of the opposite side of the mounting base 1101 and the rotating plate 1102, and a fixing spring 1104 is sleeved between the two opposite positioning blocks 1103.

[0044] During operation, the air filter box 10 is inserted into the top of the exhaust hood 8, aligning the positioning block 1001 with the positioning slot 801 until the fixing hook 1002 is pressed against the rotating plate 1102, causing the rotating plate 1102 to rotate and compress the fixing spring 1104. After the fixing hook 1002 passes the rotating plate 1102, the fixing spring 1104 rebounds and pushes the rotating plate 1102 back, causing the top of the rotating plate 1102 to engage with the fixing hook 1002, thereby securing the air filter box 10 to the top of the exhaust hood 8. The exhaust fan 9 is then activated to filter and discharge the air inside the treatment box 1, which contains waste gas and dust, through the air filter box 10.

[0045] As a further embodiment of the present invention, the swing heating mechanism 3 includes mounting plates 301, and the number of mounting plates 301 is six. Two mounting plates 301 are fixed to each other on the inner wall of the processing box 1. A connecting shaft 302 is rotatably mounted between each group of mounting plates 301 via bearings. Swing plates 303 are fixedly connected to the two ends of the connecting shaft 302 located between the two mounting plates 301. A swing groove 304 is provided through one side of the swing plate 303. A movable slide rod 305 is slidably connected between two opposing swing grooves 304. A heating lamp box 311 is fixedly connected between the sides of the two opposing swing plates 303 away from the swing grooves 304. Connecting rods 306 are fixedly connected to both ends of each movable slide rod 305. A fixed slider 307 is slidably connected through the surface of the connecting rod 306, and one side of the fixed slider 307 is fixedly connected to the inner wall of the processing box 1. A movable sleeve 308 is slidably connected through the surface of the top movable slide rod 305. A swing motor 309 is fixedly connected to the top of the processing box 1 on the side away from the sliding door panel 2, and the output end of the swing motor 309 is rotatably connected to the processing box 1 through a bearing. The output end of the swing motor 309 extends through the processing box 1 and is fixedly connected to the inside of the processing box 1 to a swing turntable 310. The edge of the swing turntable 310 is rotatably connected to the movable sleeve 308 through a bearing.

[0046] During operation, the oscillating motor 309 is started to drive the oscillating turntable 310 to rotate, which in turn drives the movable sliding sleeve 308 to rotate synchronously with the oscillating turntable 310, pulling the movable sliding rod 305 to slide up and down. The two ends of the movable sliding rod 305 slide inside the oscillating groove 304, causing the oscillating plate 303 to swing back and forth around the connecting shaft 302, which drives the heating lamp box 311 to swing and irradiate the wood surface, allowing the heating light to cover more areas of the wood surface and avoiding insufficient heating in some areas of the wood due to being far away from the heating source.

[0047] Working principle of this invention:

[0048] The movable air filter box 10 is inserted into the exhaust hood 8. Under the rebound action of the fixing spring 1104, the rotating plate 1102 is lifted and engaged with the fixing hook 1002, fixing the air filter box 10 to the top of the exhaust hood 8. After pushing the sliding door panel 2 open, the collection box 708 is placed on the top of the movable base 706, so that the limiting strip 709 is inserted into the limiting slot 707 until the elastic pad 710 is pressed against the top of the movable base 706, fixing the collection box 708 to the top of the movable base 706. Under the rebound action of the lifting spring 714, the cleaning scraper 713 is lifted and pressed against the top of the processing box 1. The electric push rod 505 is controlled to retract and pull the movable frame 506 to slide, so that the linkage is activated. The slider 507 slides along the grooves at both ends of the movable frame 506, pushing the connecting slide bar 504 to slide to both sides, pushing the movable clamping block 503 to slide away from each other inside the movable groove 502, lifting the wood and suspending it between the two limiting turntables 501, so that the two ends of the wood are stuck between the corresponding four movable clamping blocks 503. The electric push rod 505 is controlled to extend and lift the movable frame 506, so that the connecting slide bar 504 pulls the movable clamping block 503 to slide closer to each other inside the movable groove 502, until the movable clamping block 503 is close to the two ends of the wood, clamping and fixing the wood between the four movable clamping blocks 503, so that the three pieces of wood are respectively fixed between the two opposite limiting turntables 501.

[0049] Pushing the sliding door panel 2 to close activates the swing motor 309 in the swing heating mechanism 3. The output of the swing motor 309 drives the swing turntable 310 inside the processing box 1 to rotate. During rotation, the moving sleeve 308 slides along the surface of the top moving slide rod 305, thereby driving the top moving slide rod 305 to move up and down reciprocally. The top moving slide rod 305 is linked with the two sets of moving slide rods 305 below through the connecting rod 306, causing the swing plate 303 to swing back and forth, so that the heating lamp box 311 swings to control the light to shine on the wood surface, ensuring that the light swings evenly on the wood surface. Activating the dual-output shaft motor 601 drives the rotating column 602 to rotate, causing the drive turntable 604 to drive the linkage bar 605 to move, causing the two opposing dials 405 to rotate, driving the cylindrical pin 406 to engage with the intermittent slot 402, pushing the intermittent turntable 401 to drive the limit turntable 501 to rotate intermittently, thus clamping... The wood, fixed between two limit turntables 501, is rotated to ensure that the surface of the wood is intermittently facing the swing heating mechanism 3 for uniform baking. At the same time, the exhaust fan 9 is started. When the wood is heated and baked inside the processing box 1, it generates exhaust gas, wastewater and dust. The air mixed with exhaust gas and dust inside the processing box 1 is drawn out from the exhaust hood 8. The air mixed with exhaust gas and dust is filtered by the air filter box 10, and the clean air is discharged from the exhaust fan 9. At the same time, the drive motor 703 is started to drive the reciprocating screw 701 to rotate, and the moving seat 706 is controlled to slide back and forth on the surface of the two limit slide rods 705, which drives the cleaning scraper 713 to slide on the top inside the processing box 1. Under the rebound action of the lifting spring 714, the cleaning scraper 713 slides close to the top inside the processing box 1, and scrapes away the water droplets condensed on the top inside the processing box 1. The scraped water droplets flow into the collection box 708 for centralized treatment.

[0050] After the wood heat treatment is completed, the drive motor 703, the dual-shaft motor 601, and the exhaust fan 9 are stopped, so that the linkage bar 605 stops driving the dial 405 to rotate, ensuring that the limit turntable 501 stops the wood from rotating inside the treatment box 1. The swing heating mechanism 3 is turned off and the wood is no longer baked. The drive motor 703 stops rotating, so that the moving seat 706 drives the collection box 708 to stand still on the surface of the reciprocating screw 701. The cleaning scraper 713 is still at the top inside the treatment box 1 and no longer scrapes off the water droplets condensed at the top inside the treatment box 1. At the same time, the exhaust fan 9 stops controlling the inside of the treatment box 1. The sliding door 2 is pushed open, the electric push rod 505 is controlled to retract, and the moving frame 506 is pulled to push the connecting slide bar 504, so that the four moving clamps 503 are released at both ends of the wood, making it easy to remove the baked wood from between the two limit turntables 501 for replacement.
