Ventilating device for plant seedling nursing in full-sealed environment

Abstract

The invention discloses a ventilating device for plant seedling nursing in full-sealed environment. The ventilating device comprises a ventilating device main body. One side of the ventilating device main body is provided with a glass bearing plate made of poison-free and environment-friendly glass; a control panel and a corrugated pipe are arranged on the top of the ventilating device main body; the ventilating device main body is adhered to the control panel via heat-resistant super glue; a plastic branch pipe is arranged on one side of the venting device main body; the plastic branch pipe is parallel to the corrugated pipe; and a hanger is arranged on one end of the internal surface of the ventilating device main body. By the use of the ventilating device for the plant seedling nursing in the full-sealed environment, internal air environment of a plant greenhouse can be improved, combustible and harmful substances in the air can be eliminated and internal temperature and cleanness of the greenhouse air can be guaranteed; in the full-sealed plant nursing environment, seedlings can be nursed via a multi-layer seedling nursing rack, so seedling nursing work can be individually conducted; the layers can be evenly ventilated and demands for ventilation of plant seedling nursing can be met; and with an exhausting device and the work of a draught fan, plant seedling nursing work in the full-sealed environment can be achieved.

Description

technical field [0001] The invention relates to the technical field of ventilation devices, in particular to a ventilation device for plant seedling raising in a fully enclosed environment. Background technique [0002] The so-called ventilation device is an environmental control technology that controls the spread and harm of air pollutants by means of ventilation dilution or ventilation elimination, and realizes the quality assurance of indoor and outdoor air environment for plant seedlings in a fully enclosed environment. Function, due to the respiration of plants, etc., increases the concentration of carbon dioxide and water vapor, and also pollutes the environment, for the health and comfort of plants, fresh air must be introduced from the outside to replace the dirty air inside, in addition, ventilation can also regulate the interior temperature. In the prior art, there are mainly two ventilation methods for raising seedlings in greenhouses (including plastic greenhou...

AI Technical Summary

Problems solved by technology

In the prior art, there are two main ventilation methods for growing seedlings in greenhouses (including plastic greenhouses, glass greenhouses, etc.) in facility agriculture. One is to adopt the method of only installing two-way fans, blowing fresh air into the room or blowing the indoor The method of extracting air and exhausting it to the outside realizes indoor ventilation and fresh air supplementation; another method is to open the covers on both sides of the greenhouse to allow natural ventilation. These ventilation methods all have the following deficiencies: First, the indoor ventilation is not uniform; The second is that the energy consumption of fan ventilation is large, and the third is that it cannot solve the requirements for uniform ventilation conditions when planting seedlings, especially the uniform ventilation, dehumidification, humidification, refrigeration, and O2 required for high-density seedling cultivation in multi-layer seedling racks in a closed environment , CO2 supplementation and other needs
