Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Reference Figure 1 , Figure 2 and Figure 4The utility model provides an embodiment: a drying device for the production of polystyrene foam boards, comprising a bottom plate 1, a heating tank 2 is fixedly connected to the top of the bottom plate 1, a heating wire 3 is arranged on the inner wall of the heating tank 2, a top cover 7 is slidably connected to the top of the heating tank 2, a motor 8 is fixedly connected to the top of the top cover 7, a rotating shaft 9 is fixedly connected to the output end of the motor 8, a plurality of connecting plates 10 are fixedly connected to the outside of the rotating shaft 9, a fixing seat 11 is fixedly connected to the outside of the connecting plate 10, a screw rod 12 is threadedly connected to the outside of the fixing seat 11, two supporting vertical plates 4 are fixedly connected to the top edge of the bottom plate 1, two supporting vertical plates 4 are fixedly connected to the top of the top plate 5, two cylinders 6 are fixedly connected to the bottom of the top plate 5, the output ends of the two cylinders 6 are fixedly connected to the top of the top cover 7, and the top edge of the top cover 7 A vacuum pump 14 is fixedly connected, and an exhaust pipe 15 is fixedly connected to the input end of the vacuum pump 14. The end of the exhaust pipe 15 away from the vacuum pump 14 is fixedly connected to the top edge of the top cover 7. An exhaust pipe 16 is fixedly connected to the output end of the vacuum pump 14. The end of the exhaust pipe 16 away from the vacuum pump 14 is fixedly connected to an installation box 18. An air supply pipe 17 is fixedly connected to the left side of the installation box 18. The end of the air supply pipe 17 away from the installation box 18 is fixedly connected to the outer wall of the heating tank 2. A dehumidification component is arranged inside the installation box 18. A handle 13 is fixedly connected to the side end of the screw rod 12. The bottom end of the rotating shaft 9 is rotatably connected to the inner bottom wall of the heating tank 2. The exhaust pipe 15 and the air supply pipe 17 are connected. A collecting box 26 is fixedly connected to the bottom of the installation box 18, and the bottom of the collecting box 26 is fixedly connected to the top of the base plate 1.
[0031] Specifically, the bottom plate 1 serves as the base of the entire device and provides a stable support for other components. The heating tank 2 serves as the main place for drying. It provides an enclosed space for the foam board so that it can be evenly heated under the action of the heating wire 3. The heating wire 3 is the heat source for drying. It generates heat through electric current to heat the inside of the heating tank. The support vertical plate 4 connects the bottom plate 1 and the top plate 5 to provide a stable support structure for the equipment. The cylinder 6 drives the top cover 7, the rotating shaft 9, the fixed seat 11 and other components to move up and down through telescopic movement. The top plate 5 is used to connect the cylinder 6. The top cover 7 is located above the heating tank 2 and is connected to the cylinder 6. When the cylinder 6 rises, the top cover 7 opens accordingly to allow the foam board to enter and exit. When the cylinder 6 descends, the top cover 7 is reset to seal the heating tank 2. The motor 8 provides rotational power to drive the rotational movement of the shaft 9 and the foam board, which ensures that the foam board can be evenly heated during the drying process. The shaft 9 connects the motor 8 and the connecting plate 1, and is the core component of the entire rotating system. Driven by the motor, the shaft 9 drives the foam board to rotate. The connecting plate 10 connects the shaft 9 and the fixed seat 11, which plays the role of transmitting power and supporting the fixed seat 11, which ensures that the fixed seat 11 and the foam board remain stable during the rotation process. The fixed seat 11 is used to fix the foam board to ensure that it does not move during the drying process. The screw rod 12 is connected to the handle 13, and the handle is turned to rotate. The hand 13 makes the screw rod 12 fix the foam board, and the handle 13 is convenient for the worker to operate the screw rod 12 to fix or loosen the foam board. The vacuum pump 14 is used to extract the moisture inside the heating tank 2 to ensure the smooth progress of the drying process. It is connected to the heating tank 2 through the exhaust pipe 15 to transport the moisture to the dehumidification system. The exhaust pipe 15 connects the vacuum pump 14 and the heating tank 2 to provide a channel for the extraction of moisture. The exhaust pipe 16 is used to transport moisture to the inside of the installation box 18. The air supply pipe 17 connects the dehumidification system and the heating tank 2 to return the dehumidified dry gas to the inside of the heating tank 2. It ensures the recycling of hot air and improves the drying efficiency. The installation box 18 provides an installation space for the dehumidification system, which usually includes a silica gel water absorption layer 24, a hollow plate 25 and other components.
[0032] Reference Figure 1 and Figure 3 The dehumidification component includes a motor 2 19, the bottom of the motor 2 19 is fixedly connected to the top of the installation box 18, the output end of the motor 2 19 is fixedly connected to a threaded rod 20, the outer thread of the threaded rod 20 is threadedly connected to a slider 1 22, a support rod 21 is fixedly connected to the front side of the inside of the installation box 18, and a slider 27 is slidably connected to the outside of the support rod 21, and an extrusion roller 23 is rotatably connected between the slider 1 22 and the slider 2 27, a silica gel water absorption layer 24 is fixedly connected to the right side of the inside of the installation box 18, and a hollow plate 25 is fixedly connected to the side of the silica gel water absorption layer 24 away from the extrusion roller 23, and both ends of the threaded rod 20 are rotatably connected to the inner wall of the installation box 18, and the extrusion roller 23 and the silica gel water absorption layer 24 are abutted against each other.
[0033] Specifically, the motor 2 19 drives the threaded rod 20 in the dehumidification system. The threaded rod 20 is connected to the motor 2 19 and drives other components to perform dehumidification operation through rotation. The support rod 21 is used to support the squeezing roller 23. The slider 22 plays a guiding and limiting role in the dehumidification process to ensure the smooth movement of the components. The squeezing roller 23 is used to squeeze the silica gel water absorption layer 24 to squeeze out the moisture therein. The silica gel water absorption layer 24 is the core component of the dehumidification system and can absorb and store moisture. The hollow plate 25 provides a support for the squeezing roller 23, and the holes on the surface do not affect the air circulation. The collection box 26 is used to collect the moisture squeezed out from the silica gel water absorption layer 24.
[0034] Working principle: when the foam board needs to be dried, the worker starts the cylinder 6 to drive the top cover 7, the rotating shaft 9, the fixing seat 11, the connecting plate 10, and the screw 12 to move upward. When it moves to the appropriate position, the worker places the foam board between the two fixing seats 11, and turns the handle 13 to fix the foam board with the screw 12. When the foam board is placed, the cylinder 6 is started to drive the foam board into the heating tank 2 until the top cover 7 is reset, and the motor 8 is started to drive the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 drives the connecting plate 10 and the fixing seat 11 to rotate, and then drives the foam board to rotate. Under the action of the heating wire 3, the foam board is dried in all directions. When the moisture on the foam board is dried, it will turn into water vapor. When too much moisture accumulates, it will condense into water vapor. The water vapor accumulates When there is too much moisture accumulated, it affects the drying speed and causes the internal temperature of the heating tank 2 to drop. At this time, the interior needs to be dehumidified. Start the vacuum pump 14 to extract the moisture inside the heating tank 2 through the exhaust pipe 15, and then transport it to the exhaust pipe 16, and then transport it to the installation box 18. When moisture and hot air enter the installation box 18, the silica gel water absorption layer 24 will absorb the moisture, and the dry hot air will pass through the hollow plate 25 and be sent back to the heating tank 2 through the air pipe 17. When the silica gel water absorption layer 24 is saturated with water, the moisture needs to be squeezed out. At this time, start the motor 2 19 to drive the threaded rod 20 to rotate. The rotation of the threaded rod 20 simultaneously drives the slider 1 22 to move, and then drives the extrusion roller 23 to extrude the silica gel water absorption layer 24, and squeeze the moisture inside it into the collection box 26.
