Description

Technical Field

[0001] The utility model relates to the technical field of PVC material mixing devices, in particular to a mixing device for producing and processing PVC materials. Background Art

[0002] Polyvinyl chloride (PVC) is the third most produced synthetic polymer plastic in the world (after polyethylene and polypropylene), with approximately 40 million tons produced annually. PVC is a polymer formed by the free radical polymerization mechanism of vinyl chloride monomer (VCM) in the presence of initiators such as peroxides and azo compounds, or under the action of light or heat. Vinyl chloride homopolymers and copolymers are collectively referred to as vinyl chloride resins. In the daily production and processing of PVC materials, mixing equipment is required to assist in production and processing operations.

[0003] For example, application number 201721907324.9 discloses a mixing device for PVC material production and processing, including a stirring body, an inner cavity, a rotating shaft, a stirring blade, a discharge port, a machine base, a crossbeam, an inlet, an electromagnetic valve, a temperature sensor, a guide plate, an alarm light, a control panel, a support rod, a high-pressure water pump, an accelerator, a drive motor, a support leg, an outer wall and an inner wall. The mixing device for PVC raw material processing is provided with an electromagnetic valve at the inlet, which can control the quality of material delivery; the umbrella-shaped guide plate can break up the material and additives when the PVC material enters the stirring chamber from the inlet, so that the PVC material and additives fall more evenly to the bottom of the stirring chamber; when the stirring blade is running at high speed, friction occurs between the PVC raw material and the additive, and between the raw material and the inner wall, generating high temperature, causing the raw material and additive to partially melt, and the inner cavity provided on one side of the inner wall circulates the coolant to reduce the temperature to the rated value, thereby making the PVC raw material and additives more evenly stirred and improving the stirring effect.

[0004] However, although this mixing device for PVC material production and processing can perform a good mixing operation on PVC materials during use, the feeding port is often clogged due to excessive or too fast feeding, and it is not easy to clear the blockage of the feeding port. In addition, the crushing effect of larger particles of PVC materials is not high, which affects the fineness of the mixing of the PVC materials and reduces the production and processing effect of the mixing device on PVC materials.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a mixing device for the production and processing of PVC materials is proposed. Utility Model Content
