Automatic ventilation plant

Abstract

The invention discloses an automatic ventilation plant. The automatic ventilation plant comprises a plant body. A plurality of ventilation devices capable of ascending and descending are arranged on a roof of the plant body. Each ventilation device comprises a ventilation pipe body, wherein a filtering and dust removing interlayer is arranged in the middle of the ventilation pipe body, the ventilation pipe body is arranged in a through hole of the roof, a step face is arranged above the through hole, annular bosses are arranged at the two ends of the ventilation pipe body, an air inlet / air outlet is formed in the upper end of the ventilation pipe body, and an air outlet / air inlet is formed in the lower end of the ventilation pipe body. A control device is arranged on the side wall of the plant body, the control device controls opening of the air inlets and the air outlets in the ventilation pipe bodies, and a pressure sensor is arranged below each ventilation pipe body. According to the automatic ventilation plant, the top of the plant body is provided with the multiple ventilation devices capable of ascending and descending for ventilation, the ventilation devices are automatically controlled according to the pressure, the temperature and the like in the plant, and the automatic ventilation plant is very convenient to use.

Description

technical field [0001] The invention relates to the technical field of plant air circulation, in particular to an automatic ventilation plant. Background technique [0002] As a factory for production and processing, due to price increase and processing activities during use, it is easy to cause problems such as excessive internal temperature and smoke and dust. Therefore, general factory ventilation is very important. Existing factory buildings are generally equipped with ventilation structures or ventilation equipment while ventilating through doors and windows, but the general ventilation structures are connected to the outside world, and there will be situations such as high humidity and no heat preservation, etc., and the purchase of ventilation devices, Not only the cost is high, but also the installation and maintenance are very troublesome. Contents of the invention [0003] The purpose of the present invention is to provide a simple factory building automatic ven...
