Description

Technical Field

[0001] This utility model relates to a rapid cooling conveying screw structure. Background Technology

[0002] In the PVC granulation process, rapid cooling of the granules is crucial for ensuring product quality, preventing adhesion, and facilitating subsequent processing. Traditional cooling conveying devices often suffer from low cooling efficiency, complex maintenance, high noise levels, high energy consumption, and environmental pollution. Therefore, developing a PVC granulation cooling conveying device that integrates high-efficiency cooling, easy maintenance, low noise, energy saving, and environmental protection is particularly important. Existing cooling conveying devices achieve PVC granule cooling by supplying air to the outer wall of the conveying chamber. This structure results in a small contact area with the plastic granules and poor cooling effect. Utility Model Content

[0003] This utility model proposes a rapid cooling conveying screw structure, including a conveying screw body, conveying blades arranged around the conveying screw body, a water-passing cavity provided on the conveying screw body, and the outer surface of the water-passing cavity being a plastic contact layer of the conveying screw body.

[0004] In one or more embodiments, the conveying screw body is provided with an input end shank and a tail end shank, and the conveying screw body is located between the input end shank and the tail end shank.

[0005] In one or more embodiments, a water inlet is provided on the input end handle, and a water outlet is provided on the tail end handle. The water inlet is connected to a water cavity, and the water outlet is also connected to the water cavity to enable water flow.

[0006] In one or more embodiments, the water inlet is located at the front end section of the input end handle, and the water outlet is located at the rear end section of the tail end handle, which realizes water flow without affecting the rotation of the conveying screw body, thus solving the problem of the conveying screw body rotating and water flowing at the same time.

[0007] In one or more embodiments, the conveying screw body is provided with a tail end, and a reverse blade opposite to the direction of the conveying blade is provided on the tail end. A gap is provided between the reverse blade and the conveying blade. The reverse blade can effectively reduce the conveying speed of the plastic particles and make the plastic particles stay at a set position to solve the problem of the plastic particles being discharged at the set position.

[0008] In one or more embodiments, the conveying screw body is further provided with a baffle plate, which connects two adjacent conveying blades. The height of the baffle plate is less than the height of the conveying blades. The baffle plate can effectively prevent plastic particles from remaining on the top of the conveying screw body and turn the plastic particles on the top of the conveying screw body over to make them fall off, thereby increasing the running speed of the plastic particles and enabling the plastic particles to fully contact the surface of the conveying screw body, thus improving the cooling effect.

[0009] In one or more embodiments, the material-blocking and tilting plate is provided with an upper material-blocking and tilting plate and a lower material-blocking and tilting plate.

[0010] The beneficial effects of this utility model are as follows: by setting a water-filled cavity on the conveying screw, the surface of the conveying screw is cooled. When the conveying screw is conveying, it can fully contact the plastic particles. At the same time as the plastic particles come into contact with the conveying screw, the heat of the plastic particles is carried away by the water in the water-filled cavity, thereby achieving the effect of rapid cooling of the plastic particles, improving the cooling effect, and making the cooling efficient. This solves the problems of poor cooling effect and slow cooling of plastic cooling devices. Attached Figure Description
