Measurement and control type cooling equipment for screw extruder

Abstract

Measurement and control type cooling equipment for a screw extruder comprises three cooling modes, namely, the water cooling mode, the air cooling mode and the water cooling and air cooling mixed mode. The cooling equipment is composed of a detection device, a cooling device, a controller, a controllable display device and a trough structure. The cooling device comprises a water spraying device, an air supply device and a refrigeration device. The controller is electrically connected with the controllable display device. A water tank is arranged on the lower portion of the trough structure. According to the measurement and control type cooling equipment, the limitation that existing cooling equipment is singular in cooling mode is fundamentally overcome, thus, the cooling mode can be selected according to properties of polymers, the cooling equipment can accurately measure the temperature and adjust the cooling speed in real time in the cooling process, the effect that the cooling speed of the different polymers can be adjusted in time according to the properties and the extrusion conditions of the polymers, and accordingly, the stably and reliable quality is achieved; and through the mode that the temperature is precisely measured, and differentiated cooling is conduced according to different areas, energy source consumption and resource consumption are effectively reduced.

Description

technical field [0001] The invention relates to a measuring and controlling cooling device for a screw extruder. Background technique [0002] The plastic is in a highly elastic state when it is extruded by a screw extruder, and it needs to be cooled to a glass state before subsequent processing. Different plastics have different requirements for cooling methods and cooling rates. performance is greatly affected. [0003] The cooling methods of the existing cooling equipment are relatively simple, and most of them can only cool the plastic in a single way of water cooling or air cooling, and it is impossible to detect the cooling data of the plastic in real time to adjust its cooling rate and cooling method in time, resulting in low cooling efficiency and difficult Accurately and digitally achieve the required cooling state of the polymer, and then affect the properties of the polymer. Polylactic acid is a new type of biodegradable and environmentally friendly material, bu...

AI Technical Summary

Problems solved by technology

[0005] It can be seen that the cooling equipment on the existing market is difficult to meet the needs of different cooling methods for different polymer materials at the same time, and it is even more difficult to control the cooling speed according to the needs

At the same time, the existing water-cooled and air-cooled equipment adopts the method of full coverage and no difference in the whole cooling process, which leads to low cooling efficiency and serious waste of resources.
