Problems solved by technology

[0002] At present, the heating method of the screw extruder for spinning in the chemical fiber industry is to use a heating box composed of a cast aluminum heating ring and a ceramic electric heater ring to heat outside the screw, which has high energy consumption, uneven temperature, and equipment investment. Disadvantages such as large size and inconvenient maintenance, etc., the uneven thickness of the tow and broken filaments are prone to occur during the spinning process, which seriously affects the quality and cost of silk products

Abstract

The invention relates to a heating device of a screw extruder, which comprises heat-conducting oil body arranged inside an interlayer of a machine body shell, a pipeline, a valve and a heat-conducting oil heating device, and is characterized in that the heat-conducting oil heating device comprises a heating oil tank, an electric heater, an oil pump and an electrical control system, wherein the electric heater and the heating oil tank are inserted and connected with a flange and jointed for location; and the electrical control system is controlled by a control cabinet according to the information given by a temperature sensor, an electro connecting pressure gauge and the like. The heating device of the screw extruder has simple structure, convenient maintenance and use, even heating temperature and low equipment investment; and by adopting the heating device, the quality of silk product produced by the extruder is improved, and the electricity is saved by more than 30% compared with the existing way.

Description

technical field [0001] The invention relates to a heating device, in particular to a screw extruder heating device. Background technique [0002] At present, the heating method of the screw extruder for spinning in the chemical fiber industry is to use a heating box composed of a cast aluminum heating ring and a ceramic electric heater ring to heat outside the screw, which has high energy consumption, uneven temperature, and equipment investment. Large size, inconvenient maintenance and other disadvantages, it is easy to have uneven thickness of tow and broken filaments during spinning, which seriously affects the quality and cost of silk products. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a new heating device, which has simple structure, convenient use and maintenance, uniform heating temperature, and low equipment investment. Using such a heating device, the quality of silk products produced ...
