Description

Technical Field

[0001] The utility model relates to the technical field of plastic polymer production, in particular to a drying device for the production of plastic polymer products. Background Art

[0002] Since polymer plastic materials absorb moisture from the air when placed, they need to be dried before injection molding. Otherwise, defective products with flow marks or bubbles are very likely to appear during injection molding. They must be sealed and collected after drying, otherwise they are likely to absorb water again. However, general drying equipment requires manual estimation of drying time, and manual material replacement and collection after drying. This not only requires a lot of manpower, but also cannot guarantee the efficiency of drying. Manual material replacement also has the risk of polymer plastic materials absorbing water again. Therefore, plastic polymer products need to be dried.

[0003] In the prior art, a Chinese patent document with publication number CN220670002U proposes that an inner box, a second fixing plate and a filter plate are provided in a drying device for producing a uniformly heated polymer plastic film.

Specifically, the second fixing plate, the second through pipe, the second heating pipe, the through hole and the filter plate are protected by the inner box, and the inner box has a certain heat insulation effect, thereby protecting the box body and facilitating the stable operation of the equipment. Furthermore, the filter plate can filter out bacteria in the gas and liquid, and acts on the heat dissipation plate to achieve a certain degree of protection, and the practicability is relatively strong. In the above equipment, in the process of drying the plastic polymer product, the steps of the equipment for drying the plastic polymer product are relatively complicated, and a large amount of heat energy is wasted.

[0014] Beneficial effects of the utility model:

[0015] 1. This kind of drying device for the production of plastic polymer products is provided with a stirring component. The rotation of the stirring blades not only makes the wet plastic polymer products evenly mixed, but also significantly increases the gaps inside the materials. These gaps provide more circulation paths for hot air, promote the full contact between hot air and materials, thereby accelerating the evaporation rate of water and realizing a more efficient drying process. Through continuous stirring, the agglomeration and accumulation of materials in a static state are effectively prevented, ensuring the uniform distribution of materials in the charging barrel, so that each part can obtain a balanced drying effect, avoiding deformation or quality problems caused by uneven local drying. Since the stirring effect improves the drying efficiency, the device can achieve the desired drying effect in a shorter time, thereby reducing energy consumption and operating costs. At the same time, it avoids extra energy consumption and unnecessary energy waste caused by long-term drying. The stirring blades automatically clean the inner wall of the loading barrel during rotation, reducing the cleaning workload and maintenance costs caused by material adhesion, and extending the service life of the equipment. Through the automatic control of the blower and motor, the whole process from feeding, stirring to drying is realized through automatic operation, which reduces the need for manual intervention and improves production efficiency and convenience of operation.

[0016] 2. This kind of drying device for the production of plastic polymer products is provided with a stirring component and a drying component. Through the design of the heat conductive sheet, heat transfer between the small area and the large area inside the drying shell is realized. The humid hot air in the small area releases heat when passing through the heat conductive sheet, heating the cold dry air in the large area and converting it into hot dry air. This process not only improves the heat exchange efficiency, but also realizes the recycling of heat energy that may have been wasted, significantly reduces energy consumption, minimizes heat energy loss, and improves the overall energy utilization efficiency. Compared with cold dry air, hot dry air has a higher temperature and lower relative humidity, and can more effectively take away moisture on the surface of plastic polymer products, thereby accelerating the drying process and shrinking Short production cycle. Since the hot air is fully heated and evenly distributed in the drying shell, the hot dry air entering the loading barrel can act more evenly on the surface of the material, avoiding the problem of uneven local drying and improving the overall quality of the product. Various components in the device, such as hot air blowers and honeycomb rotors, are modularly designed for easy replacement and maintenance, which improves the operational flexibility of the equipment. Through the design of the sump and drain pipe, the water droplets generated inside the device are discharged in time, which effectively reduces the accumulation of moisture inside the equipment, reduces the risk of equipment damage due to moisture corrosion, and extends the service life of the equipment. By recycling and utilizing the originally wasted heat energy, the maximum utilization of resources is achieved and the dependence on external energy is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

A first gear 13 is fixedly installed at the power output end of the motor 30, a triangular fixing frame 28 is fixedly installed on the inner wall of the charging barrel 6, three stirring blades 18 are arranged below the triangular fixing frame 28, and a plurality of second gears 14 are rotatably installed above the triangular fixing frame 28, the first gear 13 is respectively meshed with the three second gears 14, three third gears 15 are rotatably installed below the triangular fixing frame 28, the three second gears 14 are respectively fixedly connected with the three third gears 15, three fourth gears 16 are rotatably installed below the triangular fixing frame 28, the three third gears 15 are respectively meshed with the three fourth gears 16, second fixing rods 17 are respectively fixedly installed below the three fourth gears 16, the three second fixing rods 17 are respectively fixedly connected with a plurality of stirring blades 18, a filter screen 11 is arranged at the connection between the other end of the drying shell 7 and the charging barrel 6, and a ladder 8 is fixedly connected to the outside of the drying shell 7.

[0027] First, the gas is dried by the drying device 5 and then transported to the charging barrel 6 through the blower 2. After the plastic polymer product in the charging barrel 6 is filled, the motor 30 is started to drive the first gear 13 to rotate. The first gear 13 is meshed with the second gear 14. The second gear 14 is rotated by the rotation of the first gear 13. The second gear 14 is fixedly connected with the third gear 15. The second gear 14 is meshed with the third gear 15. The third gear 15 is rotated by the rotation of the second gear 14. The third gear 15 is meshed with the fourth gear 16. The fourth gear 16 is rotated by the rotation of the third gear 15. The fourth gear 16 is fixedly connected to the second fixed rod 17. The second fixed rod 17 is rotated by the rotation of the fourth gear 16. The second fixed rod 17 is connected to the stirring rod 17. The blades 18 are fixedly connected, and the second fixed rod 17 rotates to drive the stirring blades 18 to rotate. The wet plastic polymer products are easy to agglomerate or accumulate in a static state, which will hinder the evaporation of water. The stirring blades 18 rotate to stir the originally wet plastic polymer products evenly, increase the contact area with the air, and are conducive to the rapid evaporation of water. During the stirring process, the gaps in the wet objects are opened, allowing air to flow more smoothly, keeping the objects loose, which is conducive to the uniform evaporation of water. While the stirring blades 18 rotate, they will also scratch the inner wall of the loading barrel 6 to prevent the wet plastic polymer products from adhering to the inner wall of the loading barrel 6, causing agglomeration and accumulation, thereby increasing the drying efficiency, avoiding deformation caused by uneven drying, and improving the overall quality of the product.

[0028] like Figures 1 to 4 As shown, the drying component includes a baffle 19 fixedly installed inside the drying shell 7, a hot air blower 20 fixedly installed above the baffle 19, a third fixed rod 21 fixedly installed on the right side of the baffle 19, a bearing 22 rotatably installed on the right side of the third fixed rod 21, a plurality of fan blades 23 fixedly installed on the bearing 22, a honeycomb rotor 24 fixedly installed on the right side of the bearing 22, a plurality of heat conducting plates 25 fixedly connected to the baffle 19 on the right side of the honeycomb rotor 24, a water collecting tank 31 fixedly connected to the drying shell 7 below the heat conducting plates 25, a drain pipe 9 fixedly installed below the water collecting tank 31, an exhaust pipe 10 fixedly connected to the drying shell 7 on the right side of the water collecting tank 31, two exhaust holes 26 are provided on the exhaust pipe 10, and an exhaust fan 27 fixedly connected to the right side of the exhaust pipe 10.

[0029] The baffle 19 is arranged in an "L" shape, dividing the interior of the drying shell 7 into two areas: a large area and a small area. After the plastic polymer products fill the loading barrel 6, the drying component starts to operate, and the exhaust fan 27 starts to rotate to drive the air in the device to circulate. The exhaust fan 27 blows the air into the loading barrel 6 through the drying shell 7, taking away the moisture on the surface of the wet plastic polymer products. The wet and cold air will enter the honeycomb rotor 24 along the large area of ​​the drying shell 7, and the honeycomb rotor 24 will dry the wet and cold air and turn it into dry and cold air. The hot air blower 20 is fixedly mounted on the baffle 19 and arranged in the small area of ​​the drying shell 7 to heat the air in the small area inside the drying shell 7. Under the blowing of the hot air from the hot air blower 20, the hot air will take away the moisture remaining in the honeycomb rotor 24 in the small area of ​​the drying shell 7, and the plurality of blades 23 fixedly mounted on the bearing 22 will rotate, and part of the moisture remaining in the honeycomb rotor 24 will continuously rotate to the small area inside the drying shell 7, and the moisture will be taken away by the hot air blown by the hot air blower 20. At the same time, the part of the heat conductive sheet 25 in the small area of ​​the drying shell 7 will absorb the heat of the humid hot air and become hot. Since the large area inside the drying shell 7 is dry and cold wind and the small area inside the drying shell 7 is hot and humid wind, the water vapor in the area where the heat conductive sheet 25 exists will condense into water droplets, which will drip onto the water collecting tank 31 due to gravity and be led out of the device through the drain pipe 9, so as to reduce the accumulation of moisture inside the device. Reducing moisture can protect the equipment from corrosion, extend the service life of the equipment, keep the inside of the equipment dry, and reduce the possibility of failure. , ensuring that the heat exchange surface is clean and unobstructed, thereby improving the heat exchange efficiency, the humid hot air is discharged from the exhaust pipe 10 through the exhaust hole 26, and after the heat conductive sheet 25 is heated, the cold dry air in a large area inside the drying shell 7 passing through the heat conductive sheet 25 will be heated into hot dry air, and then drawn into the loading barrel 6 by the exhaust fan 27. Compared with cold dry air, hot dry air can accelerate the drying efficiency. The heat conductive sheet 25 can recycle heat, and the originally wasted heat energy can be reused, thereby reducing energy waste, improving energy utilization efficiency, reducing energy consumption, and reducing energy costs.
