Oxygen aeration system and plant factory with the oxygen aeration system

Abstract

The present invention discloses an oxygen aeration system and a plant factory with the oxygen aeration system. The oxygen aeration system comprises a nutrient solution box and a cultivation box, a water pump is disposed on a bottom part of the nutrient solution box, a liquid inlet valve and a filter screen are disposed between the water pump and the cultivation box, the water pump and the cultivation box are connected through a liquid inlet pipe, a liquid return hole is disposed in a right side wall of a lower end of the cultivation box, a filter screen and a liquid return valve is disposed between the liquid return hole and the nutrient solution box, and a dissolved oxygen concentration sensor is disposed at an inner side wall of the nutrient solution box. The plant factory with the oxygen aeration system comprises the nutrient solution box, a cultivation zone bottom plate and a cabinet, wherein the cultivation zone bottom plate is disposed inside the cabinet body, the nutrient solution box, a first exhaust fan, a power supply and a vent hole are disposed at a lower end of the cultivation zone bottom plate, and a first cultivation zone, a second cultivation zone and a third cultivation zone are disposed from bottom to top in turn on the cultivation zone bottom plate. The oxygen aeration system can detect content of dissolved oxygen in real time, so as to timely determine if oxygen aeration shall be carried out, and oxygen aeration can be rapidly and effectively carried out.

Description

technical field [0001] The invention relates to a plant factory, in particular to an aeration system and a plant factory with the aeration system. Background technique [0002] The concentration of dissolved oxygen in water is related to the growth and respiration of plant roots. When the concentration of dissolved oxygen in water is too low, the roots of plants cannot respire well, which will affect the healthy growth of plants, and the water is also prone to stink at this time. Existing plant factories seldom take this into consideration. They only feel to increase the dissolved oxygen concentration in water through water circulation. There is no real-time detection of the dissolved oxygen concentration in the existing water, and it is impossible to judge in real time whether the dissolved oxygen content in the water needs to be supplemented; The effect of increasing the dissolved oxygen content in water only through circulation is not direct, obvious and rapid enough.

[0002] The concentration of dissolved oxygen in water is related to the growth and respiration of plant roots. When the concentration of dissolved oxygen in water is too low, the roots of plants cannot respire well, which in turn affects the healthy growth of plants, and the water is also prone to stink at this time.

Existing plant factories seldom take this into consideration. They only feel to increase the dissolved oxygen concentration in water through water circulation. There is no real-time detection of the dissolved oxygen concentration in the existing water, and it is impossible to judge in real time whether the dissolved oxygen content in the water needs to be supplemented; The effect of increasing the dissolved oxygen content in water only through circulation is not direct, obvious and rapid.
