Technical Field
[0001] This utility model relates to the field of PVC granule processing technology, specifically a cooling and drying device for PVC granule processing. Background Technology
[0002] PVC granules, or polyvinyl chloride granules, are a common type of synthetic material granules that have wide applications in various fields such as industry, construction, medical care, and daily life.
[0003] Before industrially produced PVC granules are processed into hard granules, they need to be heated to a certain temperature to form them. The next step is to turn the formed granules into granules. After they become granules, the granular PVC needs to be cooled and dried. However, existing methods only cool and dry the granules during the falling process, which results in a short cooling and drying time and poor cooling and drying effect. Therefore, those skilled in the art have proposed a cooling and drying device for PVC granule processing to solve the problems mentioned in the background. Utility Model Content
[0004] The purpose of this invention is to provide a cooling and drying device for PVC granule processing, so as to solve the problems mentioned in the background art.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0020] Please see Figures 1-2 A cooling and drying apparatus for PVC granule processing includes a drying chamber 1, and further includes:
[0021] The material holding mechanism includes a drying tray 8 and a bracket 2. Several sliders 7 arranged in a ring are installed on the bottom of the drying tray 8. A ring slide rail 6 that slides with the sliders 7 is installed on the bracket 2. A through hole 9 is opened at the bottom of the drying tray 8. An elastic element is connected to the bracket 2.
[0022] A rotating mechanism is installed inside the drying chamber 1 to drive the drying tray 8 to rotate;
[0023] A shaking mechanism is installed in the drying chamber 1 to drive the drying tray 8 to shake.
[0024] A drying mechanism is installed on the drying box 1 and is used to cool and dry the PVC particles in the drying tray 8.
[0025] By opening the drying chamber 1 and placing the PVC granules on the drying tray 8, then closing the drying chamber 1, the drying mechanism is started to dry the PVC granules in the drying tray 8. The rotating mechanism, in conjunction with the shaking mechanism, causes the PVC granules in the drying tray 8 to shake, so that the PVC granules can be evenly covered in the drying tray 8 and continuously turned over, which facilitates the drying mechanism to dry the PVC granules evenly and also prevents the PVC granules from sticking together.
[0026] In one embodiment, the elastic element includes a guide rod 3 installed inside the drying chamber 1. The guide rod 3 is slidably connected to the bracket 2. A top plate 4 is installed on the top of the guide rod 3, and a spring 5 is provided between the inner wall of the drying chamber 1 and the top plate 4.
[0027] Under the elastic tension of spring 5, bracket 2 is subjected to downward elastic tension, which, together with the shaking mechanism, enables bracket 2 to swing up and down, so that drying tray 8 can swing up and down.
[0028] In one embodiment, the rotating mechanism includes a motor 10 installed at the bottom of the drying chamber 1. The driving end of the motor 10 is connected to a drive shaft 11, and the drive shaft 11 is slidably connected to a shaped rod 12, which is connected to the drying tray 8.
[0029] When the drying mechanism dries the PVC particles in the drying tray 8, the motor 10 drives the drive shaft 11 to rotate, the drive shaft 11 drives the shaped rod 12 to rotate, and then drives the drying tray 8 to rotate. The slider 7 at the bottom of the drying tray 8 slides along the annular slide rail 6, so that the PVC particles in the drying tray 8 can be spread flat on the drying tray 8, which is convenient for cooling and drying the PVC particles.
[0030] In one embodiment, the shaking mechanism includes a bracket 13 mounted on the bottom of the drying chamber 1, a rotating shaft rotatably mounted on the bracket 13, a cam 15 mounted on the rotating shaft, a second bevel gear 17 mounted on the drive shaft 11, and a first bevel gear 16 meshing with the second bevel gear 17 mounted on the rotating shaft.
[0031] Because of the elastic element, the bracket 2 is in contact with the cam 15. When the drive shaft 11 rotates, the shaft will also rotate under the drive of the meshing first bevel gear 16 and second bevel gear 17, causing the cam 15 to rotate. This will drive the bracket 2 to move up and down along the guide rod 3, causing the drying tray 8 to shake up and down. This allows the PVC particles to be evenly covered in the drying tray 8 and to be continuously turned over, making it convenient for the drying mechanism to dry the PVC particles evenly.
[0032] In one embodiment, the drying mechanism includes a processing box 18 installed on the top of the drying chamber 1. The processing box 18 is connected to an air inlet pipe 22 and a conveying pipe 19. The conveying pipe 19 is connected in sequence to an air pump 20 and a drying rack 21. The air pump 20 is installed on the inner wall of the drying chamber 1. The processing box 18 is provided with absorbent cotton 23.
[0033] During the drying process, the air pump 20 is started to draw in air. The outside air enters the processing box 18 through the air inlet pipe 22, is filtered by the absorbent cotton 23, and is then transported to the drying rack 21 through the conveying pipe 19 and sprayed out. The sprayed air cools and dries the PVC particles in the drying tray 8.
[0034] This invention involves opening the drying chamber 1 and placing PVC granules on the drying tray 8, then closing the drying chamber 1 and starting the drying mechanism to dry the PVC granules in the drying tray 8. The rotating mechanism, in conjunction with the shaking mechanism, causes the PVC granules in the drying tray 8 to shake, ensuring that the PVC granules are evenly distributed in the drying tray 8 and are constantly turned over. This facilitates uniform drying of the PVC granules by the drying mechanism and also prevents the PVC granules from sticking together.

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.
