Abstract

The invention disclosed in the invention belongs to the technical field of textile printing and dyeing equipment, in particular to an online air exhaust automatic control device, comprising a machine base, a preset air exhaust device and a chassis, and the machine base, the preset air exhaust device and the chassis are used in cooperation with each other, The preset air exhaust device includes a bottom cover, a support plate is arranged on the top of the bottom cover, a support ring is fixedly installed on the top of the support plate, a cover is arranged on the top of the bottom cover, and the opening of the wind plate is controlled by a controller, The negative pressure fan exhausts a pair of preset air exhaust devices. The preset air exhaust device extracts the hot air in the drying room. At the same time, the temperature sensor detects the hot air. The thermostat detects whether the temperature in the drying room reaches the standard. When it is high, the controller controls the air baffle to open, and the second negative pressure fan works with the plate cooler at the same time. The effect of oven temperature.

Description

technical field

[0001] The invention relates to the technical field of textile printing and dyeing equipment, in particular to an online exhaust automatic control device. Background technique

[0002] In the process of textile printing and dyeing, in the drying room of the tenter, combustible gas such as natural gas will be used to heat the drying room, which is dangerous. Therefore, the drying room needs to be vented regularly.

[0003] The prior art has the following deficiencies: the existing air is usually sensed and operated manually, and the worker judges when the air is needed and how long the air is exhausted based on experience, and this control method cannot be accurate. If the exhaust time is too long, the temperature in the drying room is too low, and the drying room needs to be reheated to the preset temperature, which will increase energy consumption; if the exhaust time is short, the humidity in the drying room will increase, which will affect the speed of the...
