Description

Technical Field

[0001] The utility model belongs to the technical field of wooden pallet processing, and particularly relates to a drying device for wooden pallet processing. Background Art

[0002] A wooden pallet is a wooden pallet made of natural wood and is the most widely used wooden pallet at present. A wooden pallet is a horizontal platform device used for containerizing, stacking, handling, and transporting goods and products placed as a unit load. It is generally made of wood, metal, or fiberboard and is convenient for loading, unloading, handling unit materials, and small quantities of materials. The wooden pallet is the most common type of pallet. Before use, the moisture content of the wooden pallet needs to be reduced and the internal stress needs to be eliminated, so the wooden pallet needs to be dried.

[0003] For example, the Chinese patent with the publication number CN214307908U discloses a wooden pallet drying device for wooden pallet production, belonging to the technical field of wooden pallet processing equipment. It includes a pallet pushing component, an exhaust passage, and several groups of pallet supporting components. A sealing box is provided on the back of the drying cabinet, and a sealing door hinged to it is provided on the front of the drying cabinet. The pallet pushing component includes a material moving component, a pushing bar, and two mounting plates. Jet pipes are provided on the side walls of each mounting plate. Intake pipes are provided on both sides at the bottom of the drying cabinet, and each intake pipe corresponds to a jet pipe. Each group of pallet supporting components includes two supporting cross bars. Through the pallet pushing component of the utility model, the pushing bar can push each placed wooden pallet outward, eliminating the need for manual extraction of the wooden pallet. And the activated carbon filter screen is used to filter the impurity particles in the waste gas. The worker can clean the activated carbon filter screen by opening the sealing strip and manually taking out the mounting frame through the discharge slot.

[0004] The above patent has the following problems:

[0005] When the above patent is in use, there are some disadvantages. For example, the above device uses flue gas to dry and repel insects from the wooden pallet, and the high-temperature flue gas continuously entering the drying cabinet is directly discharged to the outside through the exhaust passage, resulting in heat loss. The discharged heat energy cannot be utilized, causing waste of resources and additional economic expenses. During the process of drying the wooden pallet with high-temperature flue gas, water vapor will also be generated and attached to the top of the inner cavity of the drying cabinet. When the water vapor accumulated on the top of the inner cavity of the drying cabinet is too much, it will also fall onto the wooden pallet below, affecting the drying of the wooden pallet. In view of this, we propose a drying device for wooden pallet processing. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a drying device for wooden pallet processing to solve the problems raised in the above background art.

[0007] In view of this, the utility model provides a drying device for processing wooden pallets, including a drying cabinet, and further including:

[0008] A sealed box fixedly installed on one side of the drying cabinet;

[0009] A trapezoidal distillation hood fixedly installed on the top of the drying cabinet, and one side of the trapezoidal distillation hood is connected to a heating pipe through a connecting pipe. The bottom end of the heating pipe extends into the sealed box, and a sealed door is slidably installed at the feed inlet of the drying cabinet;

[0010] A grid pipe fixedly installed at the bottom of the inner cavity of the drying cabinet, and several feed ends of the grid pipe penetrate through one side of the inner cavity of the drying cabinet and one side of the sealed box and extend into the inner cavity of the sealed box. Several bearing nets are slidably installed above the grid pipe and inside the drying cabinet;

[0011] A first water collecting plate and a second water collecting plate. The first water collecting plate is fixedly installed at the bottom of the trapezoidal distillation hood, and a trapezoidal net is fixedly installed on the first water collecting plate. The second water collecting plate is fixedly installed inside the heating pipe, and a conical net is fixedly installed on the second water collecting plate. Plastic films are sleeved on both the conical net and the trapezoidal net;

[0012] A fan fixedly installed inside the heating pipe, and several heating wires are fixedly installed below the fan and inside the heating pipe;

[0013] A driving mechanism located on the heating pipe and used to drive the fan to rotate;

[0014] Heat insulation layers are fixedly installed on the surfaces of the drying cabinet, the heating pipe, the sealed box, the connecting pipe, the trapezoidal distillation hood and one side of the sealed door.

[0015] In this technical solution, through the drying cabinet, heating tubes, sealed box, connecting pipes, trapezoidal distillation hood, sealed door and heat preservation layer provided, it is ensured that the fan is driven to rotate by the driving mechanism, and several heating wires are started. The rotating fan sucks the air above the conical net into the lower part of the fan in the heating tube, and then the fan blows the air through several heating wires. The several heating wires generate heat and heat the passing air to produce high-temperature air. Under the blowing action of the fan, the high-temperature air in the heating tube enters the inner cavity of the sealed box. Subsequently, the high-temperature air in the inner cavity of the sealed box enters the grid tube through several feeding ends of the grid tube. Then, the high-temperature air in the grid tube is discharged upward through several holes on the grid tube, and the wooden pallet on the bearing net is dried. Subsequently, the high-temperature air in the drying cabinet enters the trapezoidal distillation hood. Then, the high-temperature air in the trapezoidal distillation hood enters the heating tube through the connecting pipe. Through the above operations, the high-temperature air in the overall device can form a heat cycle. Under the action of the heat preservation layer, the heat energy loss in the overall device can be avoided, thereby reducing the power consumption, preventing the waste of electric energy and additional economic expenses;

[0016] By further setting the first water collecting plate and the second water collecting plate, water vapor will be generated when the high-temperature air dries the wooden pallet on the bearing net. The water vapor follows the air flow through the trapezoidal net, and the water vapor is easily attached to the plastic film on the trapezoidal net and condenses into water droplets, which flow down along the plastic film on the trapezoidal net to the first water collecting plate. Subsequently, the remaining water vapor follows the air flow through the connecting pipe into the heating tube. When the water vapor entering the heating tube passes through the conical net, the water vapor is easily attached to the plastic film on the conical net and condenses into water droplets, which flow down along the plastic film on the conical net to the second water collecting plate. It is ensured that during the process of drying the wooden pallet by the high-temperature air, the water vapor in the high-temperature air is collected, the moisture in the high-temperature air is reduced, and the drying of the wooden pallet is accelerated. At the same time, the inner wall of the trapezoidal distillation hood is of an inclined structure, and even if there are water droplets condensed by water vapor, they will fall onto the second water collecting plate for collection.

[0017] In the above technical solution, further, the driving mechanism includes:

[0018] A motor, the motor is fixedly installed on the top of the sealed box, and one end of the output shaft of the motor penetrates through the circumferential wall of the heating tube and is fixedly installed with a first bevel gear. A second bevel gear is meshed and installed on the first bevel gear, and the second bevel gear is fixed to the fan through a transmission rod.

[0019] In this technical solution, the motor is powered on and started. The output shaft of the motor drives the first bevel gear to rotate. The rotation of the first bevel gear drives the second bevel gear to rotate. The second bevel gear drives the fan to rotate through the transmission rod. When the fan rotates, it will absorb the air at the top of the inner cavity of the heating tube and blow it into the inner cavity of the sealed box. During the blowing process, the blown air will be heated by several heating wires and form high-temperature air.

[0020] In the above technical solution, further, it further includes:

[0021] A cross beam, the cross beam is fixedly installed inside the heating pipe and is located at the bottom of the second bevel gear. The transmission rod is located inside the cross beam, and the transmission rod is rotatably connected to the cross beam. The two ends of the transmission rod are tightly welded to the second bevel gear and the fan respectively. The output shaft of the motor is rotatably connected to the heating pipe. The first bevel gear is located below the second water collecting plate.

[0022] In this technical solution, it is ensured that the transmission rod can rotate normally on the cross beam. At the same time, the structural stability of the transmission rod, the fan and the second bevel gear is ensured, and it is ensured that the output shaft of the motor can rotate normally inside the heating pipe.

[0023] In the above technical solution, further, it further includes:

[0024] Two drain pipes, the two drain pipes are respectively fixedly installed on the heating pipe and the trapezoidal distillation hood, and the two drain pipes are respectively communicated with the heating pipe and the trapezoidal distillation hood. One ends of the two drain pipes are respectively in contact with the top of the second water collecting plate and the top of the first water collecting plate. Sealing plugs are inserted and installed in both drain pipes.

[0025] In this technical solution, when the overall device stops running, through the two drain pipes provided, the operator first pulls out the sealing plug in one of the drain pipes, so that the liquid collected on the first water collecting plate flows out through one of the drain pipes. Subsequently, the sealing plug in the other drain pipe is pulled out, so that the liquid on the second water collecting plate flows out through the other drain pipe. Sealing plugs are inserted in both drain pipes to ensure the airtightness of the two drain pipes.

[0026] In the above technical solution, further, it further includes:

[0027] An air inlet pipe, the air inlet pipe is fixedly installed on the heating pipe and is located above the conical net. A wind blocking plate is inserted and installed at the feed inlet of the air inlet pipe.

[0028] In this technical solution, before the overall device runs, the operator can lift the wind blocking plate so that the heating pipe is connected to the outside through the air inlet pipe. When the fan rotates, the heating pipe will draw in a part of the external air through the air inlet pipe. After the overall device works for a period of time, the operator presses down the wind blocking plate to seal the air inlet pipe, so that there is enough air for internal circulation inside the overall device.

[0029] In the above technical solution, further, the drying cabinet, the heating pipe, the sealing box, the connecting pipe and the trapezoidal distillation hood are of an integrally formed structure, and a sealing gasket is fixedly installed on the other side of the sealing door.

[0030] In this technical solution, the structures of the drying cabinet, heating pipes, sealed box, connecting pipes, and trapezoidal distillation hood are ensured to be stable to guarantee the overall sealing performance of the device. Meanwhile, through the provided sealing gasket, when the sealing door is closed at the feeding port of the drying cabinet, the sealing gasket can abut against the feeding port of the drying cabinet and the sealing door to ensure that the feeding port of the drying cabinet is sealed.

[0031] In the above technical solution, further, the conical net has a conical structure, and the cross-section of the trapezoidal net has a trapezoidal structure.

[0032] In this technical solution, through the provided conical net, it is convenient for water vapor to adhere to the plastic film on the conical net. Meanwhile, it is convenient for the water vapor that has condensed into water droplets to slide down along the plastic film on the conical net to the second water collecting plate. By setting the trapezoidal net on the first water collecting plate, when the water vapor rises, the water vapor will adsorb on the plastic film on the trapezoidal net and condense into water droplets, and then slide down along the plastic film on the trapezoidal net to the first water collecting plate obliquely. This gradually reduces the moisture in the hot air inside the overall device.

[0033] In the above technical solution, further, the number of the heating wires is at least three.

[0034] In this technical solution, it is ensured that the air in the heating pipes is fully heated to guarantee the heating efficiency of the device.

[0035] The beneficial effects of the present utility model are as follows:

[0036] 1. For the drying equipment for processing wooden pallets, through the cooperation of the provided heating pipes, sealed box, sealing door, connecting pipes, trapezoidal distillation hood, fan, heating wires, driving mechanism, and heat preservation layer, after the fan is driven by the driving mechanism, the air blown by the fan will pass through several heating wires and be heated to form high-temperature air. Under the blowing of the fan, the high-temperature air inside the overall device can form a hot circulation airflow. Under the action of the heat preservation layer, the overall device can reduce the loss of heat energy, ensure that the heat inside the overall device can be effectively recycled and continuously utilized, thereby avoiding the consumption of electric energy resources and additional financial expenses. At the same time, it can raise the temperature of the wooden pallets in the drying cabinet as a whole, and even if there are pests on the wooden pallets, they will be killed and eradicated under the continuous high temperature.

The drying equipment for processing wooden pallets, through the cooperation of the trapezoidal distillation hood, the first water collecting plate, the second water collecting plate, the conical net and the trapezoidal net, when the high-temperature air dries the wooden pallets on the bearing net, water vapor will be generated. The water vapor follows the air flow through the trapezoidal net, and the water vapor is easily attached to the plastic film on the trapezoidal net and condenses into water droplets, which flow along the plastic film on the trapezoidal net to the first water collecting plate. Subsequently, the remaining water vapor follows the air flow through the connecting pipe and enters the heating pipe. When the water vapor entering the heating pipe passes through the conical net, the water vapor is easily attached to the plastic film on the conical net and condenses into water droplets, which flow along the plastic film on the conical net to the second water collecting plate. It ensures that during the process of drying the wooden pallets with high-temperature air, the water vapor in the high-temperature air is collected, the moisture in the high-temperature air is reduced, and the drying of the wooden pallets is accelerated. At the same time, the inner wall of the trapezoidal distillation hood is of an inclined structure, and even the water droplets condensed by the water vapor will fall onto the second water collecting plate for collection.

[0054] Embodiment 1:

[0055] Please refer to Figure 1 - Figure 10 As shown, this embodiment provides a drying device for processing wooden pallets, which includes a drying cabinet 1, and further includes:

[0056] A sealed box 3, which is fixedly installed on one side of the drying cabinet 1;

[0057] A trapezoidal distillation hood 12, which is fixedly installed on the top of the drying cabinet 1, and one side of the trapezoidal distillation hood 12 is connected to a heating pipe 2 through a connecting pipe 5. The bottom end of the heating pipe 2 extends into the sealed box 3, and a sealed door 4 is slidably installed at the feed inlet of the drying cabinet 1;

[0058] A grid pipe 9, which is fixedly installed at the bottom of the inner cavity of the drying cabinet 1, and several feed ends of the grid pipe 9 penetrate through one side of the inner cavity of the drying cabinet 1 and one side of the sealed box 3 and extend into the inner cavity of the sealed box 3. Above the grid pipe 9 and slidably installed inside the drying cabinet 1 are several bearing nets 11;

[0059] The water collecting plate one 16 and the water collecting plate two 17. The water collecting plate one 16 is fixedly installed at the bottom of the trapezoidal distillation hood 12, and a trapezoidal mesh 25 is fixedly installed on the water collecting plate one 16. The water collecting plate two 17 is fixedly installed inside the heating tube 2, and a conical mesh 24 is fixedly installed on the water collecting plate two 17. Plastic films are sleeved on both the conical mesh 24 and the trapezoidal mesh 25;

[0060] The fan 18. The fan 18 is fixedly installed inside the heating tube 2, and a number of heating wires 19 are fixedly installed below the fan 18 and inside the heating tube 2;

[0061] The driving mechanism. The driving mechanism is located on the heating tube 2 and is used to drive the fan 18 to rotate;

[0062] Heat insulation layers are fixedly installed on the surfaces of the drying cabinet 1, the heating tube 2, the sealed box 3, the connecting pipe 5, the trapezoidal distillation hood 12 and one side of the sealed door 4.

[0063] Among them, by setting the drying cabinet 1, the heating tube 2, the sealed box 3, the connecting pipe 5, the trapezoidal distillation hood 12 and the sealed door 4 as well as the heat insulation layer, it is ensured that the driving mechanism drives the fan 18 to rotate, and a number of heating wires 19 are started. The rotating fan 18 sucks the air inside the heating tube 2 and above the conical mesh 24 into the lower part of the fan 18. The fan 18 then blows the air through a number of heating wires 19. The number of heating wires 19 generate heat and heat the passing air to produce high-temperature air. Under the blowing action of the fan 18, the high-temperature air inside the heating tube 2 enters the inner cavity of the sealed box 3. Subsequently, the high-temperature air in the inner cavity of the sealed box 3 enters the grid tube 9 through a number of feeding ends of the grid tube 9. Then, the high-temperature air in the grid tube 9 is discharged upward through a number of holes on the grid tube 9 and dries the wooden pallets on the bearing net 11. Subsequently, the high-temperature air in the drying cabinet 1 enters the trapezoidal distillation hood 12. Then, the high-temperature air in the trapezoidal distillation hood 12 enters the heating tube 2 again through the connecting pipe 5. Through the above operations, the high-temperature air inside the overall device can form a heat cycle. Under the action of the heat insulation layer, the heat energy loss inside the overall device can be avoided, thereby reducing the power consumption, preventing the waste of electric energy and the additional economic expenses;

[0064] By further providing a water collecting plate 16 and a water collecting plate 17, when the high-temperature air dries the wooden pallets on the bearing net 11, water vapor will be generated. The water vapor will flow along the air current through the trapezoidal net 25, and it is easy for the water vapor to adhere to the plastic film on the trapezoidal net 25 and condense into water droplets, which will flow down along the plastic film on the trapezoidal net 25 to the water collecting plate 16. Subsequently, the remaining water vapor will flow along the air current through the connecting pipe 5 into the heating pipe 2. When the water vapor entering the heating pipe 2 passes through the conical net 24, it is easy for the water vapor to adhere to the plastic film on the conical net 24 and condense into water droplets, which will flow down along the plastic film on the conical net 24 to the water collecting plate 17. This ensures that during the process of drying the wooden pallets with high-temperature air, the water vapor in the high-temperature air is collected, reducing the moisture in the high-temperature air and accelerating the drying of the wooden pallets. At the same time, the inner wall of the trapezoidal distillation hood 12 is of an inclined structure, so that even if there are water droplets condensed by water vapor, they will also fall onto the water collecting plate 17 for collection.

[0088] This embodiment provides a drying device for processing wooden pallets. In addition to including the technical solutions of the above embodiment, it also has the following technical features. The number of heating wires 19 is at least three.

[0089] Among them, it ensures that the air in the heating pipe 2 is fully heated, guaranteeing the heating efficiency of the device.

[0090] Working principle: The operator holds the handle on the sealing door 4 and pulls the sealing door 4 backward, causing the sealing door 4 to slide on the drying cabinet 1. Subsequently, the operator places several wooden pallets onto several bearing nets 11 respectively. Then, the operator pushes the handle on the sealing door 4 to drive it to move on the drying cabinet 1 until the feeding port at the front side of the drying cabinet 1 is sealed. The operator lifts the air blocking plate 6, causing the air inlet pipe 7 to open. Subsequently, the motor 8 and several heating wires 19 are powered on and started. The output shaft of the motor 8 drives the first bevel gear 20 to rotate, and the first bevel gear 20 then drives the second bevel gear 21 to rotate. The second bevel gear 21 drives the fan 18 to rotate through the transmission rod 23. When the fan 18 rotates, it sucks the air above the cross beam 22 below the cross beam 22, causing a negative pressure to appear above the cross beam 22 and inside the heating pipe 2. Subsequently, a large amount of external air enters the heating pipe 2 through the air inlet pipe 7. After the motor 8 works for a period of time, the air blocking plate 6 is slid downward, causing the air inlet pipe 7 to be sealed. At this time, when the fan 18 rotates, the air blown downward will pass through several heating wires 19. The several heating wires 19 heat up and heat the passing air to generate high-temperature air. Under the action of air pressure, the high-temperature air in the heating pipe 2 enters the inner cavity of the sealing box 3. Subsequently, the high-temperature air in the inner cavity of the sealing box 3 enters the grid pipe 9. Then, the high-temperature air in the grid pipe 9 is discharged upward through several holes. During the process of drying several wooden pallets with the high-temperature air, the moisture in the wooden pallets forms water vapor and rises. After passing through the first water collecting plate 16, most of the water vapor adheres to the plastic film on the trapezoidal net 25 and condenses into water droplets. Subsequently, the water droplets flow obliquely along the plastic film on the trapezoidal net 25 to the first water collecting plate 16. Under the action of air pressure, the high-temperature air enters the heating pipe 2 through the connecting pipe 5. At the same time, the remaining part of the water vapor in the high-temperature air passes through the plastic film attached to the conical net 24 and condenses into water droplets. Subsequently, the water droplets flow obliquely along the plastic film on the conical net 24 to the second water collecting plate 17. Under the rotation of the fan 18, the high-temperature air above the cross beam 22 in the heating pipe 2 is heated by several heating wires 19 again, and then enters the inner cavity of the sealing box 3 and flows into the grid pipe 9. Through the above operations, a thermal cycle of the high-temperature air can be formed inside the overall device. Moreover, the outer walls of the drying cabinet 1, the heating pipe 2, the connecting pipe 5, the sealing box 3, and the trapezoidal distillation cover 12, as well as the side of the sealing door 4 away from the drying cabinet 1, are all protected by heat insulation layers, ensuring that the heat inside the overall device will not be lost in large amounts, enabling the heat inside the overall device to be effectively circulated and continuously utilized, thereby avoiding the consumption of electric energy resources and additional financial expenses. At the same time, it can raise the temperature of the wooden pallets in the drying cabinet 1 as a whole, and even if there are pests on the wooden pallets, they will be killed and eradicated under continuous high temperature;

[0091] After the overall device finishes working, the operator pushes the handle on the sealing door 4 to open the sealing door 4. After removing the wooden pallets on several carrier nets 11, subsequently, the sealing plugs 15 in the two drain pipes 14 are removed, so that the water collected on the first water collecting plate 16 and the water collected on the second water collecting plate 17 are discharged from the two drain pipes 14 respectively.

[0092] The embodiments of the present application have been described above in conjunction with the accompanying drawings. Without conflict, the embodiments and the features in the embodiments in the present application can be combined with each other. The present application is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them belong to the protection scope of the present application.
