Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a plastic granule extrusion drying device. Background Technology

[0002] In the plastics processing industry, drying plastic granules is a crucial step. During transportation and storage, plastic granules often absorb moisture from the air. If used directly in processing, this can lead to defects and deformation in plastic products, seriously affecting product quality.

[0003] Traditional plastic granule drying processes rely solely on hot air for heating and drying. The limited contact area between the hot air and the plastic granules, coupled with uneven hot air distribution, results in low drying efficiency and requires a long drying time. During the drying process, plastic granules are prone to localized overheating or under-drying. Furthermore, without effective cooling during hot air discharge, the emitted gas temperature can be high, causing thermal pollution to the environment and potentially posing safety hazards to operators. To address these issues, this invention provides a plastic granule extrusion drying device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a plastic granule extrusion drying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A plastic granule extrusion drying device includes a base, several support rods fixedly connected to the middle of the upper surface of the base, the upper ends of the support rods fixedly connected to the same drying barrel, a barrel lid fixedly connected to the upper surface of the drying barrel, air inlets fixedly connected to both sides of the upper surface of the barrel lid, a hot air fan fixedly connected to one side of the upper surface of the base, a cooling barrel fixedly connected to the other side of the upper surface of the base, a processing component provided at the lower end of the barrel lid, an air outlet component fixedly connected to one side of the surface of the drying barrel, a feed inlet fixedly connected to the upper end of the surface of the drying barrel, and a sealing cap hinged to the upper end of the feed inlet.

[0007] As a further improvement of this utility model, the processing component includes a rotating rod rotatably connected to the lower end of the bucket lid, several mixing rods are fixedly connected to the surface of the rotating rod, a drive motor is fixedly connected to the middle end of the upper surface of the bucket lid, and the power end of the drive motor is fixedly connected to the rotating rod.

[0008] As a further improvement of this utility model, the air outlet component includes an air outlet fixedly connected to one side of the surface of the drying barrel, a filter screen fixedly connected inside the air outlet, an air outlet pipe fixedly connected to the other end of the air outlet, and a cooling pipe fixedly connected to the other end of the air outlet pipe.

[0009] As a further improvement of this utility model, the air outlet of the hot air blower is fixedly connected to an air supply pipe, and the other end of the air supply pipe is fixedly connected to the air inlet.

[0010] As a further improvement of this utility model, a valve pipe is fixedly connected to the lower surface of the drying barrel.

[0011] As a further improvement of this utility model, a slot is provided at the middle of the upper surface of the base, and a discharge bucket is inserted into the slot.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a hot air blower and processing components, hot air is directly input into the drying drum during use, making direct contact with the plastic granules. At the same time, through the stirring of the mixing rod, the plastic granules are fully collided and dispersed in the drying drum, effectively increasing the contact area between the granules and the hot air, thereby improving the heat transfer efficiency, shortening the drying time, and increasing production efficiency.

[0014] By incorporating a cooling tank and an exhaust assembly, hot air enters the cooling pipe through the exhaust pipe after drying the plastic granules. The hot air is then thoroughly cooled within the cooling pipe, which not only reduces the temperature of the hot air and minimizes heat loss, but also heats the cooling water within the pipe, improving energy efficiency. This design avoids the potential environmental impact of directly emitting high-temperature gases, embodying a green and energy-saving design philosophy.

[0015] By setting up a drying hopper and a discharge hopper, after the plastic granules are processed, the drive motor and hot air fan are turned off and the valve pipe is opened. The dried plastic granules smoothly enter the discharge hopper through the valve pipe under the action of gravity. The operation process is simple and quick, without the need for additional power equipment or complicated operating steps, which facilitates subsequent packaging, transportation and processing, and improves production efficiency.

[0016] In summary, this utility model demonstrates significant beneficial effects in improving drying efficiency, ensuring drying quality, saving energy and protecting the environment, being easy to operate and safe and reliable, and having strong adaptability. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 A plastic granule extrusion drying device includes a base 1, several support rods 2 fixedly connected to the middle of the upper surface of the base 1, the upper ends of the several support rods 2 fixedly connected to the same drying barrel 3, a barrel cover 4 fixedly connected to the upper surface of the drying barrel 3, air inlets 5 fixedly connected to both sides of the upper surface of the barrel cover 4, a hot air blower 6 fixedly connected to one side of the upper surface of the base 1, a cooling barrel 7 fixedly connected to the other side of the upper surface of the base 1, a processing component provided at the lower end of the barrel cover 4, an air outlet component fixedly connected to one side of the surface of the drying barrel 3, a feed inlet 8 fixedly connected to the upper end of the surface of the drying barrel 3, and a sealing cap 9 hinged to the upper end of the feed inlet 8.

[0023] In this invention, the processing assembly includes a rotating rod 10 rotatably connected to the lower end of the lid 4. Several mixing rods 11 are fixedly connected to the surface of the rotating rod 10. A drive motor 12 is fixedly connected to the middle end of the upper surface of the lid 4. The power end of the drive motor 12 is fixedly connected to the rotating rod 10. When the drive motor 12 is started, it drives the rotating rod 10 and the mixing rods 11 to rotate. Through the stirring of the mixing rods 11, the plastic particles are fully collided and dispersed in the drying barrel 3, effectively increasing the contact area between the particles and the hot air, thereby improving the heat transfer efficiency.

[0024] The air outlet assembly includes an air outlet 13 fixedly connected to one side of the surface of the drying barrel 3. A filter screen 14 is fixedly connected inside the air outlet 13. An air outlet pipe 19 is fixedly connected to the other end of the air outlet 13. A cooling pipe 20 is fixedly connected to the other end of the air outlet pipe 19. The filter screen 14 prevents plastic particles from entering the air outlet pipe 19. The purified hot air enters the cooling pipe 20 through the air outlet pipe 19 and is fully cooled in the cooling pipe 20 and the cooling barrel 7. This not only reduces the temperature of the hot air and reduces the heat loss, but also heats the cooling water in the cooling pipe 20.

[0025] The outlet of the hot air blower 6 is fixedly connected to an air supply pipe 15, and the other end of the air supply pipe 15 is fixedly connected to an air inlet 5. A valve pipe 16 is fixedly connected to the lower surface of the drying barrel 3. A slot 17 is opened in the middle of the upper surface of the base 1. A discharge barrel 18 is inserted into the slot 17. The hot air generated by the hot air blower 6 is input into the drying barrel 3 through the air supply pipe 15. The plastic granules can be easily discharged through the valve pipe 16. The discharged plastic granules are collected through the discharge barrel 18.

[0026] In use, the following steps are taken: First, open the sealing cover 9 and add the plastic granules into the drying barrel 3 through the feed port 8. After adding the appropriate amount, close the sealing cover 9. At the same time, inject an appropriate amount of cooling water into the cooling barrel 7 to soak the cooling pipe 20. Then, start the drive motor 12 to drive the rotating rod 10 and the mixing rod 11 to rotate. At the same time, start the hot air blower 6 to input hot air into the drying barrel 3 through the air supply pipe 15 and the air inlet 5. The plastic granules are stirred and collided by the mixing rod 11 while contacting the hot air, which increases the contact area between the plastic granules and the hot air to achieve the drying effect. After the hot air inside the drying barrel 3 is running, it enters the cooling pipe 20 through the filter screen 14 of the air outlet 13 and the air outlet pipe 19. After being fully cooled in the cooling pipe 20 and the cooling barrel 7, it is discharged. Finally, after the processing is completed, turn off the drive motor 12 and the hot air blower 6 and open the valve pipe 16. The dried plastic granules enter the discharge barrel 18 through the valve pipe 16 to complete the discharge.
