Description

Technical Field

[0001] This utility model relates to the field of drying technology, and in particular to a high-efficiency centrifugal dryer. Background Technology

[0002] Polystyrene is typically produced by free radical polymerization of styrene monomer. The process can be continuous or batch: the monomer is first purified to remove impurities, an initiator is added, and polymerization is carried out in a reactor at 80-120℃ to form polystyrene melt. After polymerization, the granules are extruded and then dried to remove moisture: a hot air dryer is used to dry them at 60-80℃ for 2-4 hours to prevent the formation of bubbles during processing. The dried granules can be used for injection molding, extrusion, and other processing to produce various products. The entire process requires precise temperature and time control to ensure stable product performance.

[0003] Polystyrene dryers are used to remove trace amounts of moisture and volatiles from granules. This prevents defects such as bubbles and silver streaks caused by moisture vaporization during processing, ensuring the surface smoothness and mechanical properties of the finished products; reduces moisture corrosion of equipment, extending the life of molds and screws; stabilizes the moisture content of raw materials, ensuring consistent process parameters for injection molding and extrusion, and improving production qualification rates; at the same time, it reduces the release of volatiles, improves the workshop environment, meets environmental protection requirements, and ultimately improves product quality and production efficiency.

[0004] In existing technologies, some polystyrene is typically dried using hot air dryers. However, hot air dryers have temperature requirements and require a long drying time, which can reduce production efficiency, extend processing cycles, and increase energy costs. Furthermore, uneven temperature control or excessive drying time can cause localized overheating and discoloration of particles, affecting product appearance consistency and thus reducing the finished product qualification rate. Therefore, a high-efficiency centrifugal dryer is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-efficiency centrifugal dryer, which aims to improve the problem that in the prior art, some polystyrene drying is usually carried out by hot air dryer, which has temperature requirements and takes a long time to operate, resulting in low production efficiency and a decrease in product qualification rate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-efficiency centrifugal dryer includes a casing, a centrifugal mechanism installed on the inner wall of the casing, an installation mechanism installed on the top of the casing, two water pumping mechanisms installed on the inner wall of the casing, a centrifugal dust removal pipe fixedly connected to the rear side of the casing, and two airflow pipes fixedly connected to the top of the casing.

The bottom of the filter screen is fixedly connected to the bottom of the housing. A bearing is fixedly connected to the top of the drive rod. The bearing is fixedly connected to the inner wall of the housing. A loading and unloading assembly is installed on the inner wall of the filter screen. Through the above technical solution: the casing serves as the basic frame supporting all components; the centrifugal mechanism dries materials through centrifugal force; the installation mechanism facilitates component maintenance; two pumping mechanisms improve drainage efficiency; the centrifugal dust removal pipe treats dust-laden gas to prevent pollution; two airflow pipes introduce drying gas to enhance the drying effect; all components work together to improve drying efficiency; the drive motor provides power to the centrifugal mechanism and is fixed at the bottom of the casing to ensure stable operation; the drive motor drives the drive rod to rotate, which in turn drives the auger to rotate to transport materials and enhance the centrifugal effect; the filter screen intercepts materials while allowing moisture and gas to pass through; the bearings reduce friction during drive rod rotation to ensure smooth rotation; and the loading and unloading components enable material entry and exit, improving the continuity and efficiency of the centrifugal dryer.

Two rotating plates are rotatably connected to the top of the installation box. A sealing box is detachably connected to the top of the housing. Two installation rods are fixedly connected to both sides of the sealing box. A limit component is installed on the inner wall of the installation box, and a control component is installed on the inner wall of the installation box.

[0009] As a further description of the above technical solution: The limiting component includes a fixing plate, the bottom of which is fixedly connected to the top of the housing. A square block is slidably connected to the bottom of the mounting box. Two L-shaped plates are slidably connected to the top of the housing, and the bottom of the square block is slidably connected to the top of the L-shaped plate. Through the above technical solution: the fixing plate provides installation conditions for the reset spring, the square block slides at the bottom of the mounting box to drive the L-shaped plate to move, and the two L-shaped plates limit the mounting rod from both sides to achieve a stable fixation of the sealing box, ensuring that the sealing box does not loosen during operation and ensuring the sealing effect.

The above technical solution involves fixing the two ends of the reset spring. When the control component releases the restriction on the square block, the reset spring releases its elastic potential energy to push the square block to move, which in turn drives the L-shaped plate to move and release the restriction on the mounting rod, facilitating the disassembly of the sealing box and enabling rapid maintenance.

[0011] As a further description of the above technical solution: The control component includes an eccentric wheel, the bottom of which is rotatably connected to the top of the housing.

A pumping pipe is internally fixedly connected to the water pump, and a pipe exhaust valve is internally fixedly connected to the pumping pipe.

[0014] The above technical solution involves a water pump providing power to extract moisture from the casing through a water extraction pipe. An air vent valve in the pipe discharges air from the water extraction pipe to ensure smooth water extraction, improve water extraction efficiency, and promptly remove moisture from the casing to prevent moisture accumulation from affecting the drying effect, thus ensuring a highly efficient drying process.

[0015] This utility model has the following beneficial effects: 1. In this utility model, the starting of the drive motor drives the auger to rotate. While the auger rotates, the polystyrene containing water that needs to be dried is centrifugally thrown onto the surface of the filter screen. At this time, drying gas is introduced from top to bottom through the airflow pipe. Then, under the dual action of centrifugation and drying gas, the polystyrene containing water to be dried falls, and the water is thrown out and carried away by the gas. When the moisture inside the casing reaches a certain level, the water pump starts to draw away the moisture inside the casing. Then, the exhaust valve in the pipeline facilitates the auxiliary water pump to draw out the moisture through the water suction pipe, thereby completing the efficient drying.

[0016] 2. In this utility model, when the lever is turned, the eccentric wheel rotates. The rotation of the eccentric wheel causes it to no longer press against the square block. At this time, the return spring releases its elastic potential energy to push the square block out. The square block slides inside the mounting box. By controlling the sliding of the square block in the groove inside the L-shaped plate, the L-shaped plate is moved inward, so that the L-shaped plate no longer acts as a limit to the mounting rod, thereby achieving the purpose of removing the sealing box from the top of the housing.

[0027] Working principle: When the centrifugal dryer is needed, the material to be dried is put in through the feed inlet 261, and then the drive motor 21 is started. The start of the drive motor 21 drives the auger 24 to rotate. While the auger 24 is rotating, the polystyrene containing water to be dried is centrifuged and thrown onto the surface of the filter screen 25. At this time, drying gas is introduced from top to bottom through the airflow pipe 5. Then, under the dual action of centrifugation and drying gas, the water in the polystyrene containing water to be dried is thrown out and carried away by the gas. When the moisture inside the casing 1 reaches a certain level, the water pump 31 is started to pump away the moisture inside the casing 1. Then, the exhaust valve 32 in the pipeline facilitates the auxiliary water pump 31 to pump out the moisture through the water suction pipe 33, thereby completing the efficient drying and enabling the polystyrene containing water inside to dry quickly.

[0028] When it is necessary to inspect or remove the bearing 23 outside the drive rod 22, the lever 461 is moved. The movement of the lever 461 causes the eccentric wheel 463 to rotate. The rotation of the eccentric wheel 463 causes it to no longer press against the square block 453. At this time, the return spring 452 releases its elastic potential energy and pushes the square block 453 out. The square block 453 slides inside the mounting box 41. The sliding of the square block 453 in the control groove 454 inside the L-shaped plate 455 drives the L-shaped plate 455 to move inward. This makes the L-shaped plate 455 no longer act as a limit for the mounting rod 44, thereby achieving the purpose of removing the sealing box 43 from the top of the housing 1. This facilitates the inspection of the bearing 23 on the top of the housing 1. The sealing strip 6 cooperates with the sealing groove 7 to prevent dust and other foreign objects from affecting the operation of the bearing 23.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
