Description

Technical Field

[0001] This utility model relates to the field of EPS processing equipment technology, specifically to an EPS foaming particle drying device. Background Technology

[0002] EPS foam board is made by mixing expandable polystyrene particles with steam and heating to foam, and then drying and pressing it into shape. The foam board is widely used for building exterior walls, roof insulation, and packaging. After foaming, the particles have a lot of moisture and are irregular in shape. If they are directly put into the curing box, it will affect the curing efficiency and curing quality. Therefore, drying is required. The existing self-control force disclosure number CN216804075U discloses an EPS particle foaming and drying device. The foamed EPS particles are poured into the drying box through the feed pipe. The stirring blade is driven by the first drive component to rotate continuously. The stirring blade continuously turns the EPS particles that have settled to the bottom of the drying box. The steam generated during drying is discharged from the air hole, which ensures the drying time of the EPS particles and helps to improve the drying effect. In the aforementioned patent, the stirring blades rotate horizontally at the bottom of the drying chamber. The material is agitated by the water direction of the stirring blades, which cannot effectively ensure that the material at the bottom of the drying chamber is stably turned upwards. Consequently, it cannot guarantee a uniform drying effect for the material inside the drying chamber. Furthermore, the drying chamber is stuck inside the sealing frame, making it inconvenient to quickly discharge the dried material and collect it. Utility Model Content

[0003] The purpose of this utility model is to provide an EPS foamed granule drying device to solve the problems mentioned in the background art, where the stirring blades are located at the bottom of the drying chamber and rotate horizontally. The material is stirred by the water direction of the stirring blades, which cannot effectively ensure that the material at the bottom of the drying chamber is stably turned upwards, thus failing to ensure a uniform drying effect of the material in the drying chamber. At the same time, the drying chamber is stuck inside the sealing frame, making it inconvenient to quickly discharge the dried material and collect it.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an EPS foamed granule drying device, comprising a drying chamber, a support frame, and a top cover. The top cover is fixedly installed on the top of the drying chamber. A feeding assembly is fixedly installed inside the drying chamber, and a blowing assembly is fixedly installed on the outside of the drying chamber. A discharge assembly is movably installed at the bottom of the drying chamber. The feeding assembly includes a guide cylinder, which is fixedly installed at the bottom of the drying chamber. The guide cylinder is coaxial with the drying chamber. Return ports are equidistantly opened on the outer side of the bottom of the guide cylinder. A rotating shaft is provided on the inner side of the guide cylinder. A spiral auger is fixedly installed on the outside of the rotating shaft. A drive motor connected to the rotating shaft is fixedly installed on the top of the support frame.

[0005] Preferably, the blowing assembly includes an air supply pipe fixedly connected to the outside of the drying chamber, a heating cylinder fixedly connected to the end of the air supply pipe away from the drying chamber, a fan fixedly connected to the top of the heating cylinder, a controller fixedly installed on the front side of the heating cylinder, and a blowing pipe connected to the air supply pipe fixedly installed on the inside of the drying chamber.

[0006] Preferably, the blower pipe is located outside the guide tube, and an oblique blower port is provided on the inner side of the blower pipe.

[0007] Preferably, a guide sleeve is movably engaged at the top of the return material inlet, and the guide sleeve is arranged in a cone shape that gradually widens downwards.

[0008] Preferably, the bottom of the drying chamber has a limiting groove, and the discharge assembly includes an outer jacket fixedly installed on the lower outer side of the drying chamber. Support plates are fixedly connected to both the left and right sides of the outer jacket. An electric push rod is fixedly installed on the inner side of the support plate. A push block is fixedly connected to the inner side of the electric push rod. A baffle is fixedly connected to the inner side of the push block. The baffle is movably engaged with the inner side of the limiting groove.

[0009] Preferably, the inner sides of both the baffle and the limiting groove are provided with rubber sealing strips.

[0010] Preferably, the drying chamber is fixedly installed on the top of the support frame, and the top of the top cover is provided with a dehumidification pipe and a feed inlet.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. Hot air between the drying chamber and the guide cylinder comes into contact with the material for drying. The material then settles to the bottom of the drying chamber and enters the spiral auger through the return port. The drive motor drives the rotating shaft and the spiral auger to rotate. The spiral auger adheres to the inner wall of the guide cylinder and conveys the material upward. The material is conveyed from the bottom of the drying chamber to the top of the guide cylinder and then spreads outward. It passes through the drying chamber again for drying, effectively ensuring the agitation of the settled material and improving the uniformity of drying. 2. By controlling the electric push rods on both sides, the push block can be moved outward. When the push block moves, it will drive the baffle to slide outward along the limiting groove, thereby opening the bottom of the drying chamber. In conjunction with the reverse rotation of the rotating shaft, the spiral auger will rotate in the opposite direction, pushing the material downward and discharging it from the bottom of the drying chamber, which facilitates the discharge and collection of the dried material.

[0014] 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.

[0015] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: an EPS foamed granule drying device, including a drying chamber 1, a support frame 2, and a top cover 3. The top cover 3 is fixedly installed on the top of the drying chamber 1. A feeding assembly 4 is fixedly installed inside the drying chamber 1, and a blowing assembly 5 is fixedly installed on the outside of the drying chamber 1. A discharge assembly 6 is movably installed at the bottom of the drying chamber 1. The feeding assembly 4 includes a guide cylinder 41, which is fixedly installed at the bottom of the drying chamber 1. The guide cylinder 41 is coaxial with the drying chamber 1. Return ports 42 are equidistantly opened on the outer side of the bottom of the guide cylinder 41. A rotating shaft 43 is provided on the inner side of the guide cylinder 41. A spiral auger 44 is fixedly installed in the drying chamber 1, and a drive motor 45 connected to the rotating shaft 43 is fixedly installed on the top of the support frame 2. Hot air between the drying chamber 1 and the guide cylinder 41 comes into contact with the material for drying. Subsequently, the material settles to the bottom of the drying chamber 1 and enters the spiral auger 44 through the return port 42. The drive motor 45 drives the rotating shaft 43 and the spiral auger 44 to rotate. The spiral auger 44 fits against the inner wall of the guide cylinder 41 and conveys the material upward. After being conveyed from below the drying chamber 1 to above the guide cylinder 41, the material spreads outward and passes through the drying chamber 1 again for drying, effectively ensuring the agitation of the settled material and improving the uniformity of drying.

[0016] The blowing assembly 5 includes an air supply pipe 51 fixedly connected to the outside of the drying chamber 1. A heating cylinder 52 is fixedly connected to the end of the air supply pipe 51 away from the drying chamber 1. A fan 53 is fixedly connected to the top of the heating cylinder 52. A controller 54 is fixedly installed on the front side of the heating cylinder 52. A blowing pipe 55 connected to the air supply pipe 51 is fixedly installed on the inside of the drying chamber 1. An electric heating wire is installed inside the heating cylinder 52. The heating temperature is adjusted by the controller 54. When the fan 53 is running, it introduces external air into the heating cylinder 52 for heating. Then, the hot air enters the drying chamber 1 through the air supply pipe 51 and the blowing pipe 55, which enhances the stability and controllability of the drying process.

[0017] The air blowing pipe 55 is located on the outside of the guide cylinder 41, and the inner side of the air blowing pipe 55 is provided with an oblique air blowing port. The design of the air blowing port allows the hot air to be blown out at a certain angle, so that the hot air is in the drying chamber 1 and the guide cylinder 41 in a ring and comes into contact with the material, ensuring drying efficiency. The oblique air blowing port guides the airflow to form a circulation to a certain extent, avoiding the hot air from directly penetrating the material layer and causing energy waste, making the temperature field in the drying chamber 1 more uniform and reducing the situation of local overheating or insufficient drying.

[0018] The top of the return material outlet 42 is movably connected to a guide sleeve 46. The guide sleeve 46 is a cone shape that gradually widens downwards. The cone shape of the guide sleeve 46 can effectively guide the material to slide down smoothly, reduce the accumulation and blockage of the material at the return material outlet 42, and at the same time effectively disperse the material outwards, so as to fully contact the hot air and improve the drying effect.

[0019] The drying chamber 1 is fixedly installed on the top of the support frame 2. The top of the top cover 3 is equipped with a dehumidification pipe 7 and a feed inlet 8. The dehumidification pipe 7 can effectively remove the moisture generated during the drying process, keep the humidity in the drying chamber 1 within a suitable range, and further improve the drying efficiency. The feed inlet 8 facilitates the feeding of materials. The connection between the top cover 3 and the drying chamber 1 adopts a sealed structure to prevent hot air leakage, ensure the stability of the drying process and energy utilization. At the same time, the top cover 3 can be disassembled for convenient daily maintenance and cleaning.

[0020] Please see Figure 2 and Figure 5The bottom of the drying chamber 1 has a limiting groove 11. The discharge assembly 6 includes an outer jacket 61 fixedly installed on the lower outer side of the drying chamber 1. Support plates 62 are fixedly connected to both sides of the outer jacket 61. An electric push rod 63 is fixedly installed on the inner side of the support plate 62. A push block 64 is fixedly connected to the inner side of the electric push rod 63. A baffle 65 is fixedly connected to the inner side of the push block 64. The baffle 65 is movably engaged with the inner side of the limiting groove 11. By controlling the electric push rods 63 on both sides, the push block 64 can be moved outward. When the push block 64 moves, it will drive the baffle 65 to slide outward along the limiting groove 11, thereby opening the bottom of the drying chamber 1. In conjunction with the rotating shaft 43 reversing, it drives the spiral auger 44 to rotate in the opposite direction, pushing the material downward and discharging it from the bottom of the drying chamber 1, which facilitates the discharge and collection of the dried material.

[0021] Both the baffle 65 and the limiting groove 11 are equipped with rubber sealing strips on their inner sides. The design of the sealing strips effectively prevents the material from leaking from the bottom during the drying process, ensuring the sealing performance of the drying chamber 1.

[0022] Working principle: EPS particles are fed into the drying chamber 1 through the feed inlet 8. Air is drawn into the heating cylinder 52 by the fan 53. The heating element in the heating cylinder 52 is controlled by the controller 54 to heat the air, which is then sent through the air supply pipe 51 into the air blowing pipe 55. The air is blown obliquely into the drying chamber 1 from the air blowing pipe 55. The material falls inside the drying chamber 1, allowing the hot air between the drying chamber 1 and the guide cylinder 41 to contact the material for drying. The material then settles to the bottom of the drying chamber 1 and enters the return outlet 42. On the spiral auger 44, the drive motor 45 drives the rotating shaft 43 to rotate, which in turn drives the spiral auger 44 to rotate. The spiral auger 44 is attached to the inner wall of the guide cylinder 41. As the spiral auger 44 rotates, the material that gathers from the return port 42 on the spiral auger 44 is conveyed upward. After the material is conveyed from the bottom of the drying box 1 to the top of the guide cylinder 41, it rolls and spreads outward along the guide sleeve 46 and passes through the middle of the drying box 1 again for drying. This can effectively ensure the effective turning of the settled material and improve the uniform drying effect. After the material is dried, the electric push rod 63 inside the support plate 62 drives the push block 64 to move outward. The push block 64 drives the baffle 65 to slide outward along the limiting groove 11, thereby opening the bottom of the drying chamber 1. The drive motor 45 drives the rotating shaft 43 to reverse, and the rotating shaft 43 drives the spiral auger 44 to rotate in the opposite direction. The material that enters the spiral auger 44 from the return port 42 is pushed downward and discharged from the bottom of the drying chamber 1, which facilitates the discharge of the dried material and makes it easier to collect the material. The above is the working process of the whole device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
