A hot box device for a nylon yarn texturing machine

Abstract

The invention relates to a hot box device of a novel nylon yarn elasticizer. The device is in such a structural mode that three rails, six spindles and three pipes are used, an evaporation pipe (1) is connected with a condensing pipe (3) through a return liquid pipe (5), an electric heating bar (7) is installed inside the evaporation pipe (1) and is directly immersed in heat-conduction oil inside the evaporation pipe (1), heating rails (2) are communicated with the condensing pipe (3) through a pipe (8), a throttler (6) is arranged at a top end position of the pipe (8), and two vent pipes (4) are arranged near heating rails (2) which are close to two ends of the condensing pipe (3). The throttler is arranged, the inside of heating rails is full of steam, and the steam inside a hot box is circulated compulsively, so that the normal usage time of the hot box is greatly prolonged; the TherminolVP-1 or DOWTHERNA type heat-conduction oil is used, so that the safety is greatly improved when the device works at 250 DEG C; and the heating method that the electric heating bar is directly immersed in heat-conduction oil is used, so that the temperature controlling is sensitive.

Description

technical field [0001] The invention belongs to a hot box device in the textile field, in particular to a hot box device for a nylon yarn texturing machine. Background technique [0002] At present, the hot box device of the domestic professional nylon yarn texturing machine has been used by the user for more than one month, and the following problems have occurred, which seriously affect the normal spinning of the user: the hot box is unstable, and the temperature of the heating guide rail fluctuates greatly, above ±5°C ; The temperature uniformity of the hot box heating guide rail is poor, and the maximum temperature difference in the silk track is > 3°C; some hot boxes do not start; when working at 250°C, the internal pressure of the hot box is 4.47x105Pa, which is dangerous. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention further provides a hot box device for a nylon yarn texturing machine, which can...
