Online exhaust automatic control device

Abstract

The invention belongs to the technical field of textile printing and dyeing equipment, and particularly relates to an online exhaust automatic control device. The online exhaust automatic control device comprises a machine base, a preset exhaust device and a machine case, wherein the machine base, the preset exhaust device and the machine case are used in cooperation, the preset exhaust device comprises a bottom cover, a supporting disc is arranged at the top of the bottom cover, a supporting ring is fixedly installed at the top of the supporting disc, and a cover cap is arranged at the top of the bottom cover. A controller controls an air shield disc to be opened, a first negative pressure fan conducts air draft on the preset air exhaust device, the preset air exhaust device draws out hot air in a drying room, meanwhile, a temperature sensor detects the hot air, a temperature controller detects whether the temperature in the drying room reaches the standard or not, when the temperature in the drying room is too high, the controller controls the air shield disc to be opened, a second negative pressure fan and a plate cooler work at the same time, the second negative pressure fan pumps out hot air in the drying room through the preset exhaust device, and meanwhile, a humidity sensor detects the humidity of the hot air, so that an effect of precisely controlling the temperature of the drying room is achieved.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing equipment, in particular to an online air exhaust automatic control device. Background technique [0002] During the textile printing and dyeing process, combustible gases such as natural gas are used to heat the drying room in the drying room of the stenter frame, which is dangerous. Therefore, it is necessary to regularly exhaust the drying room. [0003] The existing technology has the following deficiencies: the existing ventilation is usually perceived and operated manually, and the workers judge when the ventilation is needed and how long the ventilation time is based on experience. This control method cannot be accurate. If the exhaust time is 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 inc...

Problems solved by technology

[0003] The existing technology has the following deficiencies: the existing ventilation is usually perceived and operated manually, and the workers judge when the ventilation is needed and how long the ventilation time is based on experience. This control method cannot be accurate

If the exhaust time is 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 vehicle. , which affects the quality of the fabric, and the existing exhaust device has low flow accuracy when discharging hot air, making it difficult to control the temperature in the drying room
