Description

Technical Field

[0001] This invention relates to the field of drying, specifically to a dryer and drying process for the production and processing of foamed materials. Background Technology

[0002] PU foam board is a new type of board material, which is obtained by hot-melt extrusion of foam material. PU foam board has the advantages of high temperature resistance, good impact resistance, high compressive strength, safety and environmental protection, so PU foam board has a very wide range of applications.

[0003] After the foamed board is produced, it needs to undergo pre-dehydration treatment to prevent the moisture from affecting its performance. Currently, the dehydration method for foamed boards involves placing them in a high-temperature environment—using hot air to blow on the foamed board, raising the surface temperature of the board to evaporate and expel the internal moisture. However, as the foamed board gradually dehydrates and the hot air continues to blow, the internal moisture decreases, and the outer surface temperature of the foamed board rises. If the foamed board continues to be blown by high-temperature hot air at this point, the surface of the foamed board may be damaged. Furthermore, the internal moisture of the foamed board does not require excessively high temperatures to evaporate. Therefore, the dehydration treatment of foamed boards requires staged temperature control. Summary of the Invention

[0006] Furthermore, the conveyor network is divided into multiple segments, the number of segments being consistent with the number of partitions within the installation frame, and the position of each segment of the conveyor network corresponding to the position of each partition within the installation frame; it also includes: a drive wheel fixedly connected to the conveyor roller, with two drive wheels forming a group, and the two drive wheels in the same group being respectively set on one conveyor roller connected to each of the two adjacent segments of the conveyor network, and there is a size difference between the two drive wheels in the same group; and a drive belt wound between the two drive wheels in the same group.

[0007] Furthermore, it also includes: neutralizing components connected to the mounting bracket, the number of neutralizing components being the same as the number of partitions within the mounting frame, and the neutralizing components being located below each partition of the mounting frame.

[0008] Furthermore, the neutralizing component includes: a mounting base fixedly connected to the rear of the mounting frame, the mounting base being located in the middle section of the conveyor belt; a fan blade rotatably connected to the mounting base, the rear of the fan blade being slidably connected to the mounting frame; a mounting block fixedly connected to the mounting frame; a connecting block rotatably connected to the rear of the fan blade; and a connecting rod connecting the conveyor roller and the connecting block, one end of the connecting rod being rotatably connected to the rear eccentric position of the conveyor roller, the other end of the connecting rod being rotatably connected to the end of the connecting block, and the connecting end of the connecting rod and the connecting block being slidably connected within the mounting block.

[0009] Furthermore, it also includes: vibration components connected to the mounting frame and the conveyor rollers, with the number of vibration components matching the number of partitions within the mounting frame, and a vibration component provided in the middle section of each section of the conveyor network.

[0010] Furthermore, the vibration assembly includes: a pusher block fixedly connected to the side wall of one of the conveyor rollers connected to the conveyor network, with at least two pushers provided on each conveyor roller; a mounting strip fixedly connected to the mounting bracket; a top plate rotatably connected to the mounting strip, the number of top plates being the same as the number of pushers on a single conveyor roller, the position of each top plate corresponding to the position of each pusher block, and one end of the top plate being able to contact the foam board; a torsion spring fixedly connected between the top plate and the mounting strip; and a roller rotatably connected to the other end of the top plate, the roller being able to contact the pusher block.

[0011] Furthermore, it also includes: a sliding plate within the mounting frame, the sliding plate being located at the bottom of a side wall of the mounting frame through which the foam board can pass; a roller rotatably connected to the bottom of the sliding plate; and a spring fixedly connected between the mounting frame and the sliding plate.

[0012] Furthermore, it also includes: a manifold plate fixedly connected to the mounting frame, the manifold plate being located below the conveyor network, and the manifold plate having holes; and a return pipe fixedly connected between the compressor and the manifold plate.

[0013] A drying process for a drying machine used in the production and processing of foamed materials, employing the drying machine for the production and processing of foamed materials as described in any one of claims 1-7, comprises the following specific steps:

[0014] S1. Start the compressor. The compressor delivers heat to the mounting frame through the guide plate. Place the foam board on the conveyor belt, start the motor, and the conveyor belt transports the foam board into the mounting frame.

[0015] S2. The foamed board rolls and contacts the roller, pushing the sliding plate and roller upward and entering the partition of the mounting frame. The foamed board enters different partitions in the mounting frame and will undergo staged dehydration treatment under gradually decreasing temperature and gradually increasing transport speed.

[0016] S3. During the dehydration process of the foam board, the fan blades are oscillating to evenly distribute the temperature in each section of the installation frame; the top plate is rotated to continuously strike the foam board and change its position; the manifold and return pipe return the hot flow to the compressor for reuse.

[0017] S4. After the dehydration process is completed, the foamed board is removed from the right side of the mounting frame and collected uniformly.

[0018] Beneficial effects: By setting up gradually increasing drying spaces within the installation frame and gradually rising guide plates, the foamed board passes through each zone with gradually decreasing dehydration temperature for multi-stage dehydration. This ensures effective dehydration of the foamed board while preventing damage. Compared to existing technologies, this dryer represents a significant technological improvement and offers superior performance. Furthermore, the conveyor rollers control the up-and-down movement of the fan blades, altering the air position below the installation frame zones and promoting high-temperature airflow. This results in more uniform temperature distribution within the installation frame zones, ensuring even heating of the foamed board and effective top-and-bottom drying. Finally, the conveyor rollers control the top plate to tap the foamed board, preventing uneven dehydration caused by prolonged blockage of certain areas. Attached Figure Description

Detailed Implementation

[0030] It should be noted that the technical solutions of the present invention will be described in detail and completely below with reference to the accompanying drawings and the markings in the drawings. However, the described content is only one embodiment of the technical solutions of the present invention and cannot cover all the contents of the present invention. Therefore, any embodiments derived from the embodiments given in the present invention that are obtained by those skilled in the art without substantial creation will fall within the protection scope of the present invention.

[0031] Example: A drying machine for the production and processing of foamed materials, see reference. Figures 1-4The system includes: a mounting bracket 1; a mounting frame 2 fixedly mounted on the mounting bracket 1, wherein two upright plates are provided inside the mounting frame 2, creating three independent horizontal partitions on the left and right sides of the mounting frame 2, with the volume of the three partitions increasing sequentially from left to right; and slots for foam boards to pass through the bottom of the upright plates and the bottom of the left and right side walls of the mounting frame 2; a control panel 3 fixedly mounted on the top of the mounting frame 2; and three guide plates 4 fixedly mounted on the top of the mounting frame 2, each guide plate 4 corresponding to one of the three partitions within the mounting frame 2. Specifically, the height of the three guide plates 4 is set at a specific angle. The guide plates 4 are connected to each other, with increasing height from left to right. Each guide plate 4 has an outlet slot 401 at its bottom and an inlet slot 402 on the leftmost guide plate 4. The compressor 5 is fixedly installed on the left side of the mounting frame 2. The compressor 5 is used to provide high-temperature airflow. A connecting frame 501 is provided between the compressor 5 and the inlet slot 402 of the guide plate 4. The connecting frame 501 allows the high-temperature airflow generated by the compressor 5 to enter the guide plate 4 and enter different sections of the mounting frame 2 through the outlet slot 401. The compressor 5 is electrically connected to the control panel 3 and is operated by the control panel 3.

[0032] See Figure 5 The system includes: a conveyor roller 6 rotatably mounted on the mounting frame 1; a conveyor net 7 wound between the conveyor rollers 6, the conveyor net 7 having three sections, the positions of the three sections of the conveyor net 7 corresponding to the positions of the three partitions of the mounting frame 2; a motor 8 fixedly mounted on the left side of the mounting frame 1, the output end of the motor 8 being connected to the leftmost conveyor roller 6, the motor 8 being electrically connected to the control panel 3, and the motor 8 being operated by the control panel 3; a transmission wheel 9 fixedly mounted on the conveyor roller 6, two transmission wheels 9 forming a group, the two transmission wheels 9 in the same group being respectively set on the conveyor roller 6 connected to two adjacent sections of the conveyor net 7, and in the same group of transmission wheels 9, the diameter of the left transmission wheel 9 being larger than the diameter of the right transmission wheel 9, so that the transmission speed of the three sections of the conveyor net 7 gradually increases from left to right; and a transmission belt 10 wound between the two transmission wheels 9 in the same group.

[0033] The foam board is placed on the conveyor belt 7. The control panel 3 starts the compressor 5, which transmits high-temperature airflow through the guide plate 4 into the three sections of the mounting frame 2. The control panel 3 also starts the motor 8, controlling the conveyor belt 7 to transport the foam board from left to right. The foam board is transported into the mounting frame 2. As the foam board passes through the three sections of the mounting frame 2 in sequence, the distance between the guide plate 4 and the foam board gradually increases, and the space in the three sections also gradually increases, so the temperature in the three sections decreases step by step. Therefore, when the foam board enters the first section, it completes basic dehydration, and when it enters the next section... The temperature of the foam board surface can be neutralized by the lower temperature in the second zone, preventing the surface temperature from rising continuously and thus preventing damage to the foam board. At the same time, the temperature in this zone can continue to process any remaining moisture, because after the foam board has been dehydrated in the first zone, the moisture content has been significantly reduced compared to the initial content. Therefore, the temperature in this zone is sufficient to further dehydrate the foam board. Similarly, after entering the third zone, the surface temperature of the foam board is neutralized again, and further dehydration is carried out, ensuring the dehydration effect of this dryer on the foam board.

[0034] Using this dryer, by setting up partitions with gradually increasing drying space within the mounting frame 2 and guide plates 4 with gradually increasing height, the foamed board passes through each partition with gradually decreasing dehydration temperature in sequence, undergoing multi-stage dehydration. This ensures the dehydration effect of the dryer on the foamed board while preventing damage to the foamed board. Compared with existing technologies, this dryer has significant technological improvements and significantly better performance.

[0035] See Figure 6 and Figure 7 It also includes: a neutralization component installed on the mounting frame 1. There are three sets of neutralization components, which are located below the three sections of the mounting frame 2. The neutralization components are used to even out the temperature in each section of the mounting frame 2. The neutralizing assembly includes: a mounting base 11 fixedly installed at the rear of the mounting frame 1, the mounting base 11 being located in the middle section of the conveyor network 7; a fan blade 12 rotatably installed on the mounting base 11, the rear of the fan blade 12 having a long rod portion slidably connected to the mounting frame 1, the fan blade 12's front tail swinging up and down when the long rod portion slides up and down on the mounting frame 1; a mounting block 13 fixedly installed on the mounting frame 1, the mounting block 13 having a left-right transverse sliding groove 1301; a connecting block 14 rotatably installed at the end of the long rod portion of the fan blade 12; and a connecting rod 15 installed between the conveyor roller 6 and the connecting block 14, one end of the connecting rod 15 rotatably installed at an eccentric position at the rear end of the conveyor roller 6, the other end of the connecting rod 15 rotatably connected to the end of the connecting block 14, the connecting rod 15 and the connecting block 14 being connected by a connecting shaft 1501, the connecting shaft 1501 being slidably installed in the sliding groove 1301 of the mounting block 13.

[0036] See Figure 7 When the conveyor roller 6 rotates, the right end of the connecting rod 15 connected to the conveyor roller 6 will follow the conveyor roller 6 to produce a circular displacement change, causing the connecting rod 15 to move left and right as a whole. At the same time, the connecting rod 15 rotates relative to the conveyor roller 6, and the right end of the connecting rod 15 moves up and down. The left and right movement of the connecting rod 15 will push the connecting shaft 1501 to slide left and right in the groove 1301 of the mounting block 13, thereby driving the lower end of the connecting block 14 to move left and right. The upper end of the connecting block 14 is restricted from moving left and right by the long rod of the fan blade 12. Therefore, the connecting block 14 is rotated, and the upper end of the connecting block 14 will drive the long rod of the fan blade 12 to move up and down. The blade tail at the front of the fan blade 12 swings up and down, changing the position of the air below the partition of the mounting frame 2, promoting the flow of high-temperature airflow, making the temperature in the partition of the mounting frame 2 more uniform, and allowing the bottom of the foam board to be heated as well. That is, the foam board can be heated evenly, ensuring the drying effect of the foam board from top to bottom.

[0037] See Figure 8 It also includes: a vibration assembly installed on the mounting frame 1 and the conveyor roller 6. The vibration assembly is used to vibrate the foam board and change the position of the foam board. There are three sets of vibration assemblies, and one vibration assembly is provided in the middle section of each section of the conveyor network 7. The vibration assembly includes: a pusher block 16 fixedly installed on the side wall of one of the conveyor rollers 6 connected to the conveyor network 7, with three pushers 16 correspondingly provided on each conveyor roller 6; a mounting strip 1701 fixedly installed on the mounting frame 1, the mounting strip 1701 being parallel to the conveyor roller 6; a top plate 17 rotatably installed on the mounting strip 1701, the top plate 17 being perpendicular to the conveyor roller 6, with three top plates 17 provided on each mounting strip 1701, the positions of the three top plates 17 corresponding to the positions of the three pushers 16, and a rubber pad 1702 provided at the end of the top plate 17 away from the conveyor roller 6, the rubber pad 1702 being able to contact the foam board; a torsion spring 18 fixedly installed between the top plate 17 and the mounting strip 1701; and a roller 19 rotatably installed at the other end of the top plate 17, the roller 19 being able to contact the pusher block 16.

[0038] When the conveyor roller 6 rotates, it will cause the pusher block 16 to contact the top plate 17, and push the top plate 17 upwards near the end of the pusher block 16. The top plate 17 will twist, and the torsion spring 18 will deform. When the pusher block 16 is rotated away and disengaged from the top plate 17, the torsion spring 18 will return to its original state and rotate back to the top plate 17. The other end of the top plate 17 will strike the foam board to prevent uneven dehydration caused by the foam board being blocked for a long time. The rubber pad 1702 at the end of the top plate 17 can prevent the foam board from being damaged when the top plate 17 strikes the foam board. The roller 19 makes the top plate 17 and the pusher block 16 roll in contact, making the cooperation between the top plate 17 and the pusher block 16 smoother.

[0039] See Figure 9It also includes: mounting grooves 201 on the left and right side walls and bottom of the upright plate of the mounting frame 2; a sliding plate 20 slidably installed in the mounting grooves 201; a roller 21 rotatably installed at the bottom of the sliding plate 20; and a spring 22 fixedly installed between the mounting frame 2 and the sliding plate 20. The spring 22 causes the sliding plate 20 to move down, so that the roller 21 contacts the conveyor net 7 and seals the notches on the left and right side walls and bottom of the upright plate of the mounting frame 2.

[0040] The roller 21 and sliding plate 20 can block the slots on the mounting frame 2 through which the foam board passes. When the foam board needs to enter the mounting frame 2, or enter different sections within the mounting frame 2, the foam board can push the roller 21 and sliding plate 20 upward, automatically opening the slots and passing through them. After completely entering the next section of the mounting frame 2, the foam board disengages from the roller 21, the spring 22 returns to its original position, causing the roller 21 and sliding plate 20 to move downward and return to their original position, automatically closing the slots. In this way, all three sections can be kept sealed, reducing heat loss.

[0041] See Figure 10 It also includes: a manifold 23 fixedly installed on the mounting frame 1, the manifold 23 being located below the conveyor network 7, and the manifold 23 having holes; and a return pipe 24 fixedly installed between the compressor 5 and the manifold 23, the return pipe 24 and the manifold 23 converging and collecting excess heat flow and guiding it back into the compressor 5.

[0042] Excess heat flow within the mounting frame 2 can be returned to the compressor 5 via the manifold 23 and return pipe 24 for heating and utilization, reducing heat loss, improving the energy efficiency of the dryer, and reducing energy consumption.

[0043] The drying process of a drying machine for the production and processing of foamed materials includes the following specific steps:

[0044] S1. Start the compressor 5. The compressor 5 delivers heat to the mounting frame 2 through the guide plate 4. Place the foam board on the conveyor belt 7 and start the motor 8. The conveyor belt 7 transports the foam board into the mounting frame 2.

[0045] S2. The foam board rolls and contacts the roller 21, pushing the sliding plate 20 and the roller 21 upward, opening the notch on the mounting frame 2, and entering the partition of the mounting frame 2. The foam board enters different partitions in the mounting frame 2 and will undergo staged dehydration treatment under different temperatures and different transport speeds.

[0046] S3. During the dehydration process of the foam board, the fan blades 12 are oscillating to evenly distribute the temperature in each section of the mounting frame 2; the top plate 17 is rotated to continuously strike the foam board and change its position; the manifold 23 and the return pipe 24 return the hot flow to the compressor 5 for reuse.

[0047] S4. After the dehydration process is completed, the foamed board is removed from the right side of the mounting frame 2 and collected uniformly.
