4results about How to "Eliminate temperature difference" patented technology

This utility model provides a temperature-controlled chamber for temperature measurement, relating to the technical field of temperature measurement equipment. It includes a temperature control component and a deceleration component disposed on top of the temperature control component. The temperature control component includes a chamber body and an air storage tank. A door is movably installed on the front surface of the chamber body. A set of heating wires is symmetrically fixedly installed on the inner wall of the chamber body near the upper part. A rotating rod is rotatably connected to the top of the chamber body. A set of stirring blades is arranged and fixedly installed on the outer surface of the rotating rod. A set of slide rails is symmetrically fixedly installed on the inner wall of the chamber body near the center. Through the action of the temperature control component, this utility model enables efficient and uniform mixing of the air inside the chamber, effectively eliminating significant temperature differences between the upper and lower areas, corners, and the center area. This improves the accuracy of synchronous measurement data and ensures the consistency of temperature value transmission.

This invention discloses a solid-phase thickening reactor for PETG chips, belonging to the field of polyester chip processing technology. It includes an outer cylinder with an inlet pipe and an outlet pipe installed at its top and bottom, respectively. Support legs are installed on the side of the outer cylinder. Inside the outer cylinder are a supporting cylinder and four movable inner cylinders. Connecting rings connect the supporting cylinder to the movable inner cylinders and between adjacent movable inner cylinders. This invention ensures that each chip can undergo sufficient and uniform heat exchange with the heat medium, eliminating heating "dead zones" and temperature differences in traditional equipment. Based on the synergistic effect of uniform dispersion, controllable feeding, and a three-dimensional thermal field, the raw material can undergo a thickening reaction in the reactor in an optimal state. This ensures the uniformity and thoroughness of the reaction, effectively avoiding quality problems such as chip viscosity differences and yellowing caused by uneven heating or inconsistent reaction times. Therefore, it significantly improves the final product quality, production efficiency, and batch stability of the PETG chips.
