Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and in particular to an expandable polystyrene dryer. Background Technology

[0002] Expandable polystyrene (EPS) is a new type of thermoplastic material. It is made from polystyrene beads through pre-foaming and curing, followed by steam heating and molding. EPS has the advantages of being lightweight, heat-insulating, sound-insulating, and having good cushioning properties. In the fields of packaging, building insulation, and decoration, its unique internal structure is composed of countless tiny closed pores, which give EPS its excellent properties.

[0003] The purpose of an expandable polystyrene dryer is to remove moisture from EPS materials. Moisture can interfere with many processes in EPS production and subsequent processing. During molding, moisture can cause bubbles and deformation in the product, severely affecting product quality. Through the drying process, expandable polystyrene can reach the appropriate humidity levels for subsequent processing. Using an expandable polystyrene dryer enables efficient dehydration, improves the drying efficiency of EPS materials, and shortens the production cycle.

[0004] Currently, there is a type of expandable polystyrene dryer on the market. This dryer uses a hot air circulation system to dry expandable polystyrene. During operation, hot air continuously blows through the expandable polystyrene material, removing moisture and preventing the material from affecting subsequent processing performance due to dampness. However, in actual operation, due to its single hot air outlet structure, the hot air can only be blown out from a specific direction, resulting in uneven heating of the material. During the drying process, some materials may become over-dried due to prolonged exposure to direct hot air, even turning yellow or deteriorating, while other materials may not be sufficiently heated due to distance from the hot air outlet, resulting in poor drying effect. This greatly affects the quality stability and production efficiency of expandable polystyrene products. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an expandable polystyrene dryer, comprising a shell 1, an inlet 3 on the top left side of the shell 1 for the expandable polystyrene material to enter the dryer, a hopper 4 fixedly connected to the upper left side of the shell 1 to guide the material smoothly into the inlet 3, multiple inclined plates 5 fixedly connected at equal intervals on both the left and right sides of the interior of the shell 1 to extend the residence time of the material in the dryer and increase the drying effect, multiple supports 6 fixedly connected at equal intervals on the right side of the interior of the shell 1 to support heating tubes 7 and fans 8, heating tubes 7 fixedly connected to the right side of the multiple supports 6 to generate heat and increase the internal temperature of the dryer, and fans 8 fixedly connected to the left side of the multiple supports 6 to blow the heat generated by the heating tubes 7 onto the material to accelerate the evaporation of moisture in the material, and an outlet 9 on the lower left side of the shell 1 to discharge air. The outlet 9 is used to discharge moisture generated during the drying process. Multiple baffles 10 are fixedly connected at equal intervals inside the outlet 9. The baffles 10 can prevent the material from being discharged with the moisture and can also adjust the speed and direction of the airflow. The bottom right side of the outer shell 1 is provided with a discharge port 11, which is used to discharge the dried material. The bottom inside the outer shell 1 is fixedly connected with a conveying device 12, which is used to transport the dried material to the discharge port 11. The right end of the conveying device 12 passes through the discharge port 11, so that the conveying device 12 can smoothly send the material out. The inside of the outer shell 1 is provided with a water absorption mechanism 2, which is used to absorb the water vapor inside the outer shell 1 and reduce the humidity inside the dryer. The front side of the outer shell 1 is fixedly connected with an observation window 13, which allows the operator to observe the drying status of the material inside the dryer. The outer wall of the observation window 13 is fixedly connected with a protective frame 14, which can protect the observation window 13 from damage caused by external impact.

[0033] Specifically, the material enters the dryer through the feed inlet 3, which is located on the top left side of the outer shell 1. The feed hopper 4 is fixedly connected to the upper left side of the outer shell 1. The material is smoothly guided into the feed inlet 3 through the feed hopper 4 and then enters the interior of the outer shell 1. Inside the outer shell 1, the material comes into contact with multiple inclined plates 5, which are equidistantly fixed to the left and right sides of the interior of the outer shell 1. The material slides down the inclined plates 5, extending its residence time in the dryer and increasing the drying effect. At the same time, multiple supports 6 on the right side of the interior of the outer shell 1 provide support. The supports 6 are equidistantly fixed to the right side of the interior of the outer shell 1, and the heating tubes 7 fixedly connected to their right sides start working, generating heat and raising the temperature inside the outer shell 1. Meanwhile, the fan 8 fixedly connected to the left side of the supports 6 also starts operating, dissipating the heat generated by the heating tubes 7. The air is blown towards the material to accelerate the evaporation of moisture and achieve the drying process. During the drying process, the generated moisture is discharged from the air outlet 9, which is located on the lower left side of the outer casing 1. Multiple baffles 10 are fixedly connected at equal intervals inside the outlet 9 to prevent the material from being discharged with the moisture. They can also adjust the speed and direction of the airflow. The dried material falls onto the conveying device 12 at the bottom inside the outer casing 1. The conveying device 12 is fixedly connected to the bottom inside the outer casing 1, and its right end passes through the discharge port 11, which is located at the bottom right side of the outer casing 1. The conveying device 12 transports the dried material out from the discharge port 11, completing the entire drying process. The observation window 13 allows the operator to observe the drying status of the expandable polystyrene inside the dryer.

[0034] Reference Figure 2 and Figure 5The water absorption mechanism 2 includes a fixed plate 201, which provides a mounting support base for components such as the telescopic rod 203. The left side of the fixed plate 201 is fixedly connected to the lower left side of the interior of the outer casing 1 to ensure stable installation of the fixed plate 201 within the outer casing 1. The same U-shaped frame 202 is fixedly connected to the front and rear ends of the bottom of the outer casing 1. The U-shaped frame 202 can support and limit the water absorption sponge 205. Telescopic rods 203 are fixedly connected to the front and rear sides of the bottom of the fixed plate 201. The telescopic rods 203 can move the pressure plate 204 by telescopic movement. The other ends of the two telescopic rods 203 are fixedly connected to the same pressure plate 204, so that the pressure plate 204 can be raised under the action of the telescopic rods 203. The pressure plate 204 is fixedly connected to the bottom of the pressure plate 204. The pressure plate 204 can squeeze or release the water-absorbing sponge 205 when moving. The bottom of the water-absorbing sponge 205 is fixedly connected to the bottom of the inner side of the U-shaped frame 202 to ensure that the water-absorbing sponge 205 is in a suitable position for water absorption. The bottom left side of the outer shell 1 is slidably connected to the water collection tank 206, which is used to collect the water squeezed out by the water-absorbing sponge 205. The pressure plate 204 is slidably connected to the front and rear sides inside the U-shaped frame 202, making the movement of the pressure plate 204 more stable and accurate. The size of the pressure plate 204 matches the internal size of the U-shaped frame 202 to ensure that the pressure plate 204 will not shake or deviate when moving inside the U-shaped frame 202.

[0035] Specifically, when the water absorption operation begins, the absorbent sponge 205 fully utilizes its absorbent properties. Since the bottom of the absorbent sponge 205 is fixed to the bottom inner side of the U-shaped frame 202, and the U-shaped frame 202 is fixedly connected to the front and rear ends of the bottom of the outer casing 1, this provides stable support for the absorbent sponge 205, allowing it to be positioned appropriately to fully contact the area to be absorbed and absorb a large amount of water. After the water absorption process is completed, the telescopic rods 203 connected to the front and rear sides of the bottom of the fixing plate 201 begin to function. The left side of the fixing plate 201 is fixed to the lower left side of the inner side of the outer casing 1, providing a stable support point for the telescopic rods 203. Upon receiving a command, the telescopic rods 203 begin to retract. Because the other ends of the two telescopic rods 203 are jointly fixedly connected to the pressure plate 20... 4. Therefore, the retraction of the telescopic rod 203 will cause the pressure plate 204 to move downward. During the downward movement of the pressure plate 204, it will squeeze the water-absorbing sponge 205 fixedly connected to the bottom. Since the water-absorbing sponge 205 is elastic, when it is squeezed, the water absorbed in it will be squeezed out. The squeezed water flows into the water collection tank 206 through the preset channel. The water collection tank 206 is slidably connected to the bottom left side of the outer shell 1. The operator only needs to slide the water collection tank 206 out of the outer shell 1, pour out the water inside, and then slide it back to the installation position to continue the water collection work. The pressure plate 204 is slidably connected to the front and rear sides inside the U-shaped frame 202 and matches the internal size of the U-shaped frame 202, making the pressure plate 204 more stable when moving.

[0036] Reference Figure 1 , Figure 2 and Figure 5 A switch 15 is fixedly connected to the lower front part of the outer casing 1. Switch 15 provides operators with a convenient access point to control some functions of the equipment. Switch 15 is electrically connected to the blower 8 and the telescopic rod 203, allowing operators to turn the blower 8 on or off, adjust internal airflow and heat distribution, and control the extension and retraction of the telescopic rod 203 to operate the water suction mechanism 2. A horizontal plate 16 is fixedly connected to the left side of the outer casing 1. The horizontal plate 16 provides the mounting base for the support plate 17. Support plates 17 are fixedly connected to the front and rear sides of the top of the horizontal plate 16, providing upward support. The tops of adjacent sides of the two support plates 17 are fixedly connected to the front and rear sides of the feed hopper 4, thus stably supporting the feed hopper 4 and ensuring that the material can be... The feed can smoothly enter the dryer through the feed hopper 4. The bottom four corners of the outer shell 1 and the bottom right front and rear ends of the conveying device 12 are all fixedly connected to the support feet 18. The support feet 18 support the entire dryer and keep it at a certain distance from the ground to avoid the ground conditions from adversely affecting the equipment. The outer walls of the multiple support feet 18 are respectively fixedly connected to the corresponding connecting plates 19. The connecting plates 19 enhance the connection stability between the support feet 18 and ensure the stability of the entire equipment support structure. The left side of the water collection tank 206 is fixedly connected to the handle 20. The handle 20 makes it convenient for the operator to move the water collection tank 206. The outer wall of the handle 20 is designed with rounded edges to prevent the operator from being injured when holding the handle 20, and improve the safety and comfort of operation.

[0037] Specifically, the operator can easily control the start and stop of the blower 8 via switch 15, thereby regulating the airflow inside the dryer and accelerating moisture evaporation. The cross plate 16 and the support plate 17 work together to provide stable support for the feed hopper 4, ensuring that the feed hopper 4 remains in a fixed position during use. The support feet 18 support the entire dryer, keeping the dryer at a certain distance from the ground to avoid the dryer being affected by factors such as ground moisture. When it is necessary to clean the water collection tank 206, the operator can slide the water collection tank 206 out from the bottom left side of the outer casing 1 by holding the handle 20.

[0038] Working Principle: When using the expandable polystyrene dryer, the operator pours the expandable polystyrene to be dried into the outer shell 1 through the feed hopper 4 and feed inlet 3. The material entering the outer shell 1 first falls onto the inclined plates 5. Multiple inclined plates 5 are equidistantly distributed on the left and right sides of the inner shell 1. Their inclination angle guides the material to slide down slowly, prolonging the residence time of the material in the dryer. As the material slides down the inclined plates 5, the blowers 8 installed on the left side of the support 6 blow air evenly onto the material, allowing the material to fully contact the hot air. Meanwhile, the heating tubes 7 fixed on the right side of the support 6 generate heat. The heat emitted by the heating tubes 7 mixes with the airflow from the blowers 8 to form a hot airflow, which dries the material. The material flows inside the outer shell 1 from right to left, carrying away moisture. As the hot air flows to the left, it passes through the air outlet 9, which is located in the lower left part of the outer shell 1. Multiple baffles 10 are fixedly connected at equal intervals inside the outlet 9. The function of the baffles 10 is to regulate and block the exhaust airflow, preventing the unutilized hot airflow from being discharged too quickly, and also preventing the material from escaping with the airflow, thus improving energy utilization and drying effect. After drying, the material continues to slide down and finally reaches the bottom of the outer shell 1. At this time, the conveying device 12 installed at the bottom of the inner shell 1 starts to work. The conveying device 12 transports the dried expandable polystyrene material out of the discharge port 11, ensuring that the material can be discharged smoothly and enter the subsequent processing stage.

[0039] Furthermore, moisture is generated during the drying of materials. The absorbent sponge 205 absorbs moisture inside the outer shell 1. When it is saturated, the telescopic rod 203 extends downward, causing the connected pressure plate 204 to move downward. The bottom of the pressure plate 204 is fixedly connected to the absorbent sponge 205, and the bottom of the absorbent sponge 205 is also fixedly connected to the inner bottom of the U-shaped frame 202. As the telescopic rod 203 drives the pressure plate 204 to continue downward, it squeezes the absorbent sponge 205 against the U-shaped frame 202, causing the absorbed moisture in the absorbent sponge 205 to be squeezed out and flow into the water collection tank 206. When the water collection tank 206 is full, the operator can easily pull the water collection tank 206 out of the outer shell 1 and empty the water for convenient treatment of the collected moisture.
