Description

Technical Field

[0001] The present application relates to the technical field of plate drying, and in particular to an energy-saving plate drying device that utilizes hot air circulation. Background Art

[0002] During the board manufacturing process, boards need to be dried. However, traditional board drying technologies suffer from low efficiency, high energy consumption, and inconsistent drying quality. For example, natural drying relies on weather conditions, takes months, and is easily affected by ambient humidity, resulting in uneven moisture content. Steam drying, while shortening the drying cycle, requires large boilers, resulting in high equipment costs, and significant heat loss and energy consumption during the drying process. Board drying is a critical step in determining product quality and production efficiency, but it struggles to meet the stringent requirements of the high-end market for board stability, environmental performance, and production efficiency.

[0003] The existing technology still has the following problems: 1. Existing boards are dried by manual loading, which is inefficient and difficult to control the feeding rhythm. The boards cannot be placed straight on the conveying mechanism. The boards are tilted and need to be corrected, which seriously affects the efficiency of board transportation. At the same time, the tilted boards are prone to collision with equipment. The boards tilt into the drying chamber, resulting in a change in the distance between the local board and the heat source, which makes the boards dry unevenly.

[0004] 2. The existing drying device cannot preheat the plate, resulting in heat loss mainly occurring in the gaps of the drying chamber, resulting in a low proportion of effective heat energy. The heat energy in the drying process cannot be fully utilized to preheat the plate. The unheated plate is directly exposed to a high temperature environment, and the surface temperature rises suddenly while the internal temperature remains low, which can easily cause thermal stress and cause cracks on the outer surface of the plate. In addition, when the hot air circulates on the plate, dust is easily mixed in the hot air, which will cause uneven drying on the surface of the plate, and color spots and unevenness will appear. Dust adheres to the surface of key components such as heating tubes and fan blades to form an insulation layer, resulting in a decrease in heat conduction efficiency, seriously affecting the drying efficiency of the plate and reducing the service life of the equipment. Summary of the Invention

The plates cannot be placed straight on the conveying mechanism, and the plates are placed tilted and need to be corrected, which seriously affects the efficiency of plate transportation.

The unheated plates are directly exposed to the high temperature environment, and the surface temperature rises suddenly while the internal temperature remains low, which can easily cause thermal stress and cause cracks on the outer surface of the plates. In addition, when the hot air circulates on the plates, dust is easily mixed in the hot air, which can cause uneven drying on the surface of the plates, and cause color spots and unevenness. Dust adheres to the surfaces of key components such as heating tubes and fan blades, forming an insulation layer, which reduces the heat conduction efficiency and seriously affects the drying efficiency of the plates. , and at the same time reduces the service life of the equipment. The present invention can prevent heat loss in the drying chamber through the drying component, which helps water evaporate faster and reduces stress concentration caused by temperature differences and uneven moisture during the drying process, thereby effectively preventing the plate from cracking or deformation and balancing the air pressure inside the drying chamber. In addition, the filter can prevent dust generated in the hot air circulation from adhering to the plate.

Dust filtering can ensure that the air entering the drying chamber is clean and prevent dust from contaminating the plate, thereby improving product quality and appearance and extending the service life of the equipment.

A feeding component 3 is fixedly installed on the upper surface of the drying equipment main body 1. A plate 4 is placed in the inner cavity of the feeding component 3. A drying component 5 is provided on the upper surface of the drying equipment main body 1. The first conveyor belt 2 rotates to drive the plate 4 to pass through the inner cavity of the drying component 5, and the plate 4 is placed in the feeding component 3 for loading.

The outer surface of the bottom end of the feeding rack 31 is provided with a second motor 34, and the output end of the second motor 34 is sleeved with one of the rotating rods 32. The inner cavity of the feeding rack 31 is provided with a movable groove 35, and the outer surface of the second conveyor belt 33 is fixedly installed with a push block 36. When the second conveyor belt 33 rotates, the push block 36 can pass through the inner cavity of the movable groove 35. The outer surface of the feeding rack 31 is provided with a connecting groove, which can accommodate a plate 4 to pass through the feeding rack 31. The inner cavity of the feeding rack 31 is provided with a plate 4, and the top of the push block 36 is located in the middle part of the bottom plate 4. The outer surface of the feeding rack 31 is fixed A fixed plate 37 is installed, and a correction mechanism 38 is provided in the inner cavity of the fixed plate 37. The operation of the second motor 34 drives the rotating rod 32 to rotate, and the rotation of the rotating rod 32 drives the second conveyor belt 33 to rotate. The rotation of the second conveyor belt 33 drives the push block 36 to move in the inner cavity of the movable groove 35. When the push block 36 moves in the inner cavity of the movable groove 35, it drives the plate 4 on the lowest side of the inner cavity of the feeding rack 31 to move, so that the plate 4 slides out of the connecting groove on the bottom side of the feeding rack 31, and then the plate 4 slides down in turn under the action of gravity, so that the plate 4 can be loaded in turn under the action of the push block 36, and the position of the plate 4 on the first conveyor belt 2 is corrected by the correction mechanism 38 on the fixed plate 37 to prevent collision with the equipment, and at the same time ensure the uniformity of drying of the plate 4.

[0024] See also Figure 1 and Figure 3384 is connected to the cam 386, and the cam 386 is connected to the cam 386 by the screw threaded rod 384 at the top of the cam 386.

That is, the spacing between the two guide cylinders 387 at the parallel positions can accommodate the plate 4 to pass through. When the plate 4 slides on the first conveyor belt 2, it will contact the guide cylinder 387. The guide cylinder 387 is used to correct the position of the plate 4. When the plate 4 is tilted at a certain position, it drives the correction frame 381 to shake in the inner cavity of the fixed plate 37. At this time, the first slide bar 382 slides in the inner cavity of the fixed plate 37.

[0025] See also Figure 5 and Figure 6As shown, the drying component 5 includes a drying chamber 51, the top inner walls on both sides of the drying chamber 51 are rounded, and a circulation plate 52 is fixedly installed on the inner wall of the drying chamber 51. The left and right sides of the circulation plate 52 are tightly connected to the drying chamber 51, and there is a gap between the front and rear ends of the circulation plate 52 and the inner wall of the drying chamber 51. A first fan 53 is provided on the upper surface of the circulation plate 52, and a capacitor 54 is provided on the upper surface of the circulation plate 52.

The outer surface of the preheating box 551 is fixedly installed with a fixing strip 555, and the bottom end of the fixing strip 555 is fixedly connected with a cloth bag 556. The bottom end of the cloth bag 556 is in contact with the upper surface of the first conveyor belt 2, and a hot air circulation is generated by the first fan 53 and the capacitor 54, that is, the wind forms a hot air around the circulation plate 52. The air circulation, the preheating mechanism 55 is used to preheat the plate 4, thereby saving energy. The pressure regulating mechanism 56 prevents excessive heat and is used to balance the heat of the drying chamber 51 and the preheating mechanism 55. The dustproof mechanism 57 is used to block the dust accompanying the hot air circulation and prevent the dust from adhering to the outer surface of the plate 4. When the preheating mechanism 55 is preheating, the preheating box 551 is used to prevent the heat on both sides of the drying chamber 51 from being lost from the gap, so that the heat will enter the inner cavity of the preheating box 551 during drying. The operation of the second fan 554 drives the heat in the preheating box 551 containing the connecting cover 553 into the heat pipe 552, and then enters the heat pipe 552 from the heat pipe 552 to the side near the feeding assembly 3. The inner cavity of the preheating box 551, when the board 4 enters the drying chamber 51 for drying, it first enters the preheating box 551 near the feeding assembly 3, and the board 4 is preheated by the heat in the preheating box 551. The preheating treatment can make the moisture inside the board 4 evenly distributed, reduce the moisture content gradient, and preheating can also increase the temperature of the board 4, so that it can be evenly heated and enhanced. The plasticity of the wood is enhanced, which helps the moisture evaporate faster and reduces the stress concentration caused by temperature differences and uneven moisture movement during the drying process, thereby effectively preventing the board 4 from cracking or deformation. The cloth bag 556 on the fixing bar 555 is used to prevent heat from being lost from the preheating box 551, and the cloth bag 556 is made of cloth and will not block the board 4 from entering the drying chamber 51.

[0026] See also Figure 6 、 Figure 7 and Figure 8As shown, the pressure regulating mechanism 56 includes a regulating cylinder 561, which is fixedly connected to the inner wall of the drying chamber 51 away from the feeding assembly 3, a fixing ring 562 is fixedly installed on the inner wall of the regulating cylinder 561, a connecting pipe 563 is fixedly installed on the outer surface of the fixing ring 562, a connecting hole 564 is opened on the outer surface of the connecting pipe 563, a first connecting rod 565 is fixedly installed on the middle part of the fixing ring 562, a second spring 566 is sleeved on the outer surface of the first connecting rod 565, an elastic ring 567 is slidably connected to the inner cavity of the regulating cylinder 561, the regulating cylinder 561 is located above the circulation plate 52, one end of the regulating cylinder 561 is located in the inner cavity of the preheating box 551, the second spring 566 is located between the fixing ring 562 and the elastic ring 567, the elastic ring 567 is slidably connected to the connecting pipe 563, the elastic ring 567 is slidably connected to the first connecting rod 565, and the inner cavity of the connecting pipe 563 near the fixing ring 562 is hollowed out and connected to the preheating box 551. The inner cavity of the box 551 is connected. When the heat generated in the drying chamber 51 is too high, the pressure inside the drying chamber 51 increases. At this time, the air pressure in the drying chamber 51 squeezes the elastic ring 567, driving the elastic ring 567 to slide in the inner cavity of the regulating cylinder 561. The movement of the elastic ring 567 compresses the second spring 566 and exposes the connecting hole 564 in the inner cavity of the drying chamber 51, so that the air pressure generated in the drying chamber 51 can enter the connecting pipe 563 from the connecting hole 564, and then enter the preheating box 551 adjacent to the regulating cylinder 561 from the connecting pipe 563, which can balance the internal air pressure of the drying chamber 51 and prevent heat loss, thereby recycling the collected heat. When the air pressure is relatively balanced, the elastic force of the second spring 566 drives the elastic ring 567 to slide on the first connecting rod 565, so that the elastic ring 567 blocks the connecting hole 564, thereby ensuring that the heat in the drying chamber 51 will not be lost in large quantities, facilitating the subsequent drying of the plate 4.

The dust box 573 is used to collect dust, and the shielding strip 574 is used to prevent dust from being collected in the dust box 573 and raised again. When dust is generated on the surface of the filter 572, it will cause the dust frame 571 to float in the inner cavity of the drying chamber 51, that is, the overall resistance of the filter 572 increases, causing the dust frame 571 to float in the inner cavity of the drying chamber 51.

The third spring 5769 is located between the hand-shift block 5768 and the inner wall of the fixed block 5766.

When the filter 572 is clogged, the filter 572 causes the dust frame 571 to slide in the inner cavity of the drying chamber 51 under the action of wind force. The sliding of the dust frame 571 drives the slider 5711 to slide. The sliding of the slider 5711 drives the second baffle 5761 to slide.

In addition, when the second baffle plate 5761 moves, the second connecting rod 5710 drives the first baffle plate 5751 to move. The movement of the first baffle plate 5751 makes the dustproof frame 571 and the cleaning mechanism 575 remain stable as a whole, and drives the third motor 5752 to work under the pressure of the button 5763. The work of the third motor 5752 drives the transmission belt 5753 to rotate, and the rotation of the transmission belt 5753 drives the transmission rod 5754 to rotate, and the rotation of the transmission rod 5754 drives the transmission belt The dynamic cleaning brush 5755 moves back and forth on the outer surface of the dustproof frame 571, so that the cleaning brush 5755 cleans the outer surface of the filter 572, so that the filter 572 can be automatically cleaned when it is blocked, preventing dust from being accompanied by the hot air circulation, ensuring that the plate 4 is not affected by dust when it is drying, improving the cleanliness of the outer surface of the plate 4 and the production quality of the plate 4, and the ball engagement of the positioning groove 5764 and the positioning rod 5767 prevents the button 5763 and the pressure block 5765 from being unstable during the squeezing process, that is, when the cleaning brush 5755 cleans a part of the filter 572, the filter 572 is The filter 572 is partially unblocked. At this time, if the positioning groove 5764 is not limited, the button 5763 and the pressure block 5765 will be disengaged under the elastic force of the fourth spring 579, resulting in incomplete cleaning of the filter 572. When the filter 572 is clean, the elastic force of the fourth spring 579 can drive the ball on the positioning rod 5767 and the positioning groove 5764 to disengage, thereby ensuring the stability of the cleaning brush 5755 in cleaning the filter 572. When the ball on the positioning rod 5767 and the positioning groove 5764 are engaged, it is not easy to use too much force, ensuring that the filter 572 can be reset in time after cleaning, saving energy. At the same time, when the filter 572 is partially clogged, the second shielding plate 5761 is moved to a certain extent.

When the push block 36 moves in the inner cavity of the moving groove 35, it drives the plate 4 on the lowest side of the inner cavity of the feeding rack 31 to move, so that the plate 4 slides out of the connecting groove on the bottom side of the feeding rack 31, and then the plate 4 slides down one by one under the action of gravity, so that the plate 4 can be The materials are loaded in sequence under the action of the push block 36. The position of the plate 4 on the first conveyor belt 2 is corrected by the correction mechanism 38 on the fixed plate 37 to prevent collision with the equipment. At the same time, the uniformity of drying of the plate 4 is ensured.

The preheating mechanism 55 is used to preheat the plate 4, thereby saving energy. The pressure regulating mechanism 56 prevents excessive heat and is used to balance the heat of the drying chamber 51 and the preheating mechanism 55. The dustproof mechanism 57 is used to block the dust accompanying the hot air circulation, avoid dust adhering to the outer surface of the plate 4, and improve the production quality of the plate 4.
