Description

Technical Field

[0001] This utility model relates to the field of raw material particle drying technology, specifically a raw material particle drying device for plastic products. Background Technology

[0002] Plastic products are usually made from plastic granules, which are melted at high temperatures and then manufactured using different injection molds. Plastic products may become damp after being stored for a long time, so they need to be dried by a drying device before use.

[0003] Currently, when drying plastic raw material granules, the granules are usually placed in a drying oven and then dried with hot air. To prevent the raw materials from piling up and affecting the drying effect, an agitation structure is usually set up to stir the piled-up raw material granules. However, when drying a large number of raw material granules, simply stirring can only break up the raw material granules, and the flow between different layers of raw material granules is poor, which makes it difficult to dry the raw material granules evenly.

[0004] To address the problems mentioned above, those skilled in the art have proposed a raw material granule drying device for plastic products. Utility Model Content

[0005] The purpose of this invention is to provide a raw material granule drying device for plastic products, so as to solve the problems mentioned in the background art.

[0016] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0017] Please see Figures 1-3 A drying device for raw material granules for plastic products includes a base 1, a support frame 2 mounted on the base 1, a drying chamber 3 mounted on the support frame 2, a feeding port 8 mounted on the top of the drying chamber 3, and a discharge chamber 4 connected to the feeding port 8 on the top of the drying chamber 3. Drying chambers 5 are located on both sides of the drying chamber 3, and the drying chambers 5 are connected to the discharge chambers 4 via connecting ports 6. A conveying cylinder 9 is installed inside the drying chamber 5, and the top of the conveying cylinder 9 is connected to the feeding port 8 via a guide pipe 13. A feed inlet 14 is located at the bottom of the conveying cylinder 9. A groove 15 is located at the bottom of the conveying cylinder 9 inside the drying chamber 3, and discharge ports 7 are located on both sides of the groove 15. The device also includes: A conveying assembly is disposed inside the conveying cylinder 9 and is used to convey the raw material particles in the drying chamber 5 to the feed pipe 13; A discharge assembly is disposed in the groove 15 and is used to discharge raw material particles from the drying chamber 5. A drying assembly is installed inside the drying chamber 3 and is used to dry the raw material particles in the drying chamber 5 and the material discharge chamber 4 with hot air.

[0018] This invention involves pouring raw material particles from the feeding port 8 into the discharge chamber 4 of the drying chamber 3. Hot air blown into the discharge chamber 4 by the drying component dries the falling raw material particles. The raw material particles that fall to the bottom of the discharge chamber 4 enter the drying chamber 5 through the connecting port 6. The hot air blown into the drying chamber 5 by the drying component also dries the raw material particles in the drying chamber 5. In addition, the raw material particles at the bottom of the drying chamber 5 can be continuously conveyed to the guide pipe 13 by the conveying component and fall back into the discharge chamber 4. During the falling process of the raw material particles, they can be fully and evenly dried by hot air. Compared with the method of piling up raw material particles and stirring them for drying, the drying of this application is more uniform and can ensure the effective drying time of all raw material particles, thus improving the drying effect. After drying is completed, the discharge component opens, allowing the raw material particles in the drying chamber to be discharged from the discharge port 7.

[0019] In one embodiment, the conveying assembly includes a rotating shaft 10 rotatably disposed inside a conveying cylinder 9, an auger 11 mounted on the rotating shaft 10, and a motor 12 connected to the rotating shaft 10 mounted on the top of the conveying cylinder 9.

[0020] When it is necessary to transport the raw material particles at the bottom of the drying chamber 5 to the guide pipe 13, the raw material particles enter the bottom of the conveying cylinder 9 through the feed port 14, and the motor 12 is started. The motor 12 drives the rotating shaft 10 to rotate, causing the auger 11 to rotate. The auger 11 continuously transports the raw material particles at the bottom of the conveying cylinder 9 to the guide pipe 13, so that the raw material particles re-enter the dropping chamber 4 through the guide pipe 13.

[0021] In one embodiment, the discharge assembly includes a hydraulic rod 17 installed at the bottom of the groove 15, and a baffle 16 that fits against the inner wall of the groove 15 is installed on the hydraulic rod 17. The baffle 16 is used to seal the bottom of the conveying cylinder 9.

[0022] Once the raw material particles are dried, the hydraulic rod 17 is activated, and the hydraulic rod 17 descends to open the discharge port 7. At this time, the raw material particles at the bottom of the conveying cylinder 9 will enter the groove 15 and be discharged from the discharge ports 7 on both sides, thus achieving discharge.

[0023] In one embodiment, the drying assembly includes a hot air blower 18 installed at the bottom of the drying chamber 3. The hot air blower 18 is connected to a conveying pipe 19. The conveying pipe 19 is connected to a first diversion pipe 20 that communicates with the material discharge chamber 4. The drying chamber 3 is provided with an annular pipe 22 at the bottom of the drying chamber 5. A second diversion pipe 23 that communicates with the drying chamber 5 is provided on the annular pipe 22. The annular pipe 22 is connected to the conveying pipe 19 through a connecting pipe 21.

[0024] By starting the hot air blower 18, hot air is generated and transported to the first diversion pipe 20 through the conveying pipe 19, thereby guiding the hot air into the material discharge chamber 4. At the same time, the hot air from the conveying pipe 19 will also enter the annular pipe 22 through the connecting pipe 21, and then be introduced into the drying chamber 5 from the second diversion pipe 23, thus facilitating the drying of the raw material particles in the drying chamber 5 and the material discharge chamber 4.

[0025] In one embodiment, the inner walls of the material discharge chamber 4 are provided with a plurality of staggered guide plates 24, which are inclined.

[0026] The inclined and spaced guide plates 24 can extend the time that the raw material particles fall in the discharge chamber 4, thereby facilitating the introduction of hot air into the discharge chamber 4 to have sufficient time to perform hot air drying on the raw material particles.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
