Description
Technical Field
[0001] The invention relates to the technical field of greenhouse planting, and in particular to an automatic carbon dioxide replenishing device for a stacked greenhouse. Background Art
[0002] Carbon dioxide fertilizer is increasingly used as an important nutrient fertilizer for greenhouse cultivation. The related patents and products of its generating device are also relatively common and of various styles. However, as a grower, it is hoped that its carbon dioxide generating device is simple in structure, cheap, easy to use and reliable. Chinese patent CN 205052344 U introduces a greenhouse vertical carbon dioxide generator, which has a simple structure, reliable performance, and is easy to use, which meets the needs of growers. However, some problems have been found in the long-term use of its product: (1) When the patented product was first used, the gas production per unit time was sufficient. After a period of use, the bottom plate of the generator chamber and the heating part were bonded, and the heating caused the bottom plate to warp and deform, which eventually led to uneven heating of the material in the gas generating chamber and significantly insufficient gas production per unit time; (2) Due to its own structural characteristics, the patented product is prone to dry burning; (3) Due to the structure of the patented product itself, the heating component cannot be replaced when burned and needs to be eliminated as a whole, resulting in waste; (4) With the development of advanced automation control technology, people hope that the patented product will have a higher degree of automation and reduce manpower. Summary of the invention

[0004] The technical solution of the present invention is: a stacked greenhouse carbon dioxide automatic replenishment device, including an intelligent control unit and a gas thermal decomposition reaction generating unit;
[0005] The intelligent control unit is composed of a PID temperature controller, a disc temperature sensor, a time relay, a buzzer, a carbon dioxide sensor and other conventional electrical control components; the PID temperature controller uses the disc temperature sensor to collect the temperature of the liquid heat conduction cavity to control the heating operation of the detachable heating rod; the time relay controls the rated ammonium bicarbonate feeding amount node put into the gas generating cavity, that is, after the rated ammonium bicarbonate in the gas generating cavity is generated, the circuit working mode is turned off; the buzzer alarms and notifies the user after the rated ammonium bicarbonate feeding amount in the gas generating cavity is used up; the carbon dioxide sensor collects the carbon dioxide concentration in the greenhouse, and the feedback signal controls the switch of a stacked greenhouse carbon dioxide automatic replenishment device;

[0009] The beneficial effects of the present invention are:
[0010] 1. It can quickly thermally decompose ammonium bicarbonate to produce carbon dioxide fertilizer.
[0011] By heating the ammonium bicarbonate in the gas generating chamber, it is decomposed into a mixed gas of ammonia and carbon dioxide. The mixed gas flows to the gas filter chamber. The ammonia dissolves in water and remains in the water, while the carbon dioxide is insoluble in water and overflows the water surface, enters the greenhouse exhaust system, and is then transported to various parts of the greenhouse.
[0012] 2. It has automatic compensation and automatic control functions.

[0014] 3. It has the characteristics of preventing dry burning and uneven heating, and the heating part is easy to replace when it is damaged.
[0015] The liquid heat conduction cavity contains heat conduction oil as a medium, which can prevent dry burning; the time relay turns off the circuit operation mode after the rated ammonium bicarbonate in the gas generating cavity (2a) is completely generated, which also has the function of preventing dry burning.
[0016] By utilizing the liquid form of the heat transfer oil, the deformation of the liquid heat transfer cavity caused by heating can be automatically compensated to ensure that the upper plate of the liquid heat transfer cavity is heated evenly, and ultimately ensure uniform heating of the gas generating cavity.
[0017] By utilizing the combined structure of the detachable heating rod and the liquid heat conduction cavity, when the detachable heating rod is damaged, it can be directly pulled out and replaced.
[0018] 4. Simple structure, low cost, easy to promote and use.
