Description

Technical Field

[0001] The utility model relates to the technical field of plastic production, in particular to a magnetic stirring constant temperature water bath device for plastic production. Background Art

[0002] The magnetic stirring constant temperature water bath device for plastic production is a device used to ensure that materials are evenly mixed and heated at a specific temperature. It maintains the water in the constant temperature chamber at the set temperature through a heating tube and an external heater, thereby providing a stable reaction environment; a high-speed motor drives the stirring blades for rapid stirring, improving reaction efficiency. It is suitable for various plastic production processes. This device plays an important role in the processing and production of plastic materials, improving product quality and production efficiency.

[0003] In a constant-temperature water bath reactor, relying solely on lateral stirring results in insufficient uniformity of the material in the vertical direction. In a liquid, gravity causes the material to stratify, with heavier particles sinking to the bottom and lighter liquids floating on top. During the stirring process, the flow pattern of the fluid (laminar or turbulent) has a significant impact on the mixing effect of the materials. Laminar flow leads to uneven mixing, while turbulent flow can improve mixing efficiency. Horizontal stirring cannot effectively overcome the sedimentation and aggregation of materials, especially when the stirring depth is large, and the exchange of upper and lower materials is limited. In view of this, we propose a magnetic stirring constant-temperature water bath device for plastic production. Utility Model Content
