Air return system and intelligent control system for cotton inspection thermostatic chamber

Abstract

The invention discloses an air return system and an intelligent control system for a cotton inspection constant-temperature room, and relates to the technical field of cotton inspection constant-temperature rooms. The air return system comprises a machine room, an HVI environment room is fixedly installed on one side of the machine room, an intelligent controller is arranged in the machine room, and an indoor air conditioner is arranged below the intelligent controller; a fresh air conveying channel is fixedly mounted at a left air inlet of the indoor air conditioner. According to the device, rapid humidification treatment is carried out on the interior of the HVI environment chamber, so that flammable cotton fibers in air of the HVI environment chamber are rapidly wetted, fire diffusion is restrained, automatic closing of the lower air return plenum chamber is achieved, waste water is prevented from entering an exhaust filtering pipeline through the lower air return plenum chamber during fire extinguishing, and the waste water is prevented from entering the exhaust filtering pipeline through the lower air return plenum chamber. And moreover, the cotton fiber filter plate can be automatically cleaned, so that the filter effect of the cotton fiber filter plate is better, and the service life of the cotton fiber filter plate is prolonged.

Description

technical field [0001] The invention relates to the technical field of a constant temperature room for cotton inspection, in particular to a return air system and an intelligent control system for a constant temperature room for cotton inspection. Background technique [0002] At present, during the cotton inspection process in the cotton inspection constant temperature room, cotton fiber is a good textile raw material. Cotton wadding and dust in the cotton will fill the room, and too much cotton fiber will enter the respiratory tract and lungs, which will endanger human health. At the same time, the concentration of dust in the laboratory is high, which is easy to cause fires. From picking in the farmland to ginning in the ginning factory to become raw cotton, the cotton bales are inevitably mixed with a large amount of fine debris such as leaf dust and dust.

[0002] At present, during the cotton inspection process in the cotton inspection constant temperature room, cotton fiber is a good textile raw material. Cotton wadding and dust in the cotton will fill the room, and too much cotton fiber will enter the respiratory tract and lungs, which will endanger human health. Healthy, at the same time, the concentration of laboratory dust is high, which is easy to cause fire. From picking in the farmland to ginning in the ginning factory to become raw cotton, the cotton bales are inevitably mixed with a lot of fine debris such as leaf dust and dust

[0003] Existing air return system cannot carry out smoke detection and fire prevention treatment indoors, which may lead to untimely disaster relief in the event of a fire. At the same time, the bottom air inlet is prone to water ingress during fire fighting, causing water to enter the channel and damage parts, and the filter plate is often covered with cotton. Fiber clogging results in poor detection
