Fertilization tank for micro-irrigation system

Abstract

The invention discloses a fertilization tank for a micro-irrigation system, wherein the essential of the technical scheme disclosed by the invention for solving the technical problems is as follows: the fertilization tank for a micro-irrigation system comprises a fertilization tank, wherein a glass tube is arranged on the upper part of one side of the fertilization tank; one end of a water outlet tube is connected with the upper port of the glass tube, and the other end of the water outlet tube is connected with the water outlet end of a fertilization valve on a micro-irrigation system pipeline; a water inlet tube is arranged in the fertilization tank, and the upper end of the water inlet tube is connected with the water inlet end of the fertilization valve; valves are arranged on the water inlet tube and the water outlet tube respectively; a floating ball having a specific gravity which is greater than the specific gravity of water is arranged in an inverted-conical hole in the glass tube; a scale mark for indicating the position of the floating ball is formed on the glass tube; an exhaust valve is arranged at the bottom of the glass tube; and the water outlet of the water inlet tube is formed in the centre of the bottom of the fertilization tank and not contacted with the bottom surface of the fertilization tank. Compared with the prior art, the fertilization tank for a micro-irrigation system disclosed by the invention has the remarkable advantages of being uniform in fertilization, good in effect and easy to operate.

Description

technical field [0001] The invention belongs to irrigation equipment, in particular to a micro-irrigation system fertilization tank. Background technique [0002] Commonly used fertilization equipment for micro-irrigation systems are powered fertilizer injection pumps, hydraulic piston pumps, Venturi fertilizer applicators, differential pressure fertilization devices, etc. These fertilization devices will cause uneven fertilization when there is less fertilizer liquid in the fertilization device. Defects, even the inability to fertilize due to insufficient pressure, such as Venturi fertilizer applicators, in addition, such as power fertilizer injection pumps and water-driven piston pumps, all require additional power equipment, which requires a large investment and is not suitable for low-pressure irrigation systems; differential pressure fertilization If the pressure difference between the two ends of the valve of the tank is not well controlled, the pressure difference is ...

Problems solved by technology

[0002] Commonly used fertilization equipment for micro-irrigation systems are powered fertilizer injection pumps, hydraulic piston pumps, Venturi fertilizer applicators, differential pressure fertilization devices, etc. These fertilization devices will cause uneven fertilization when there is less fertilizer liquid in the fertilization device. Defects, even the inability to fertilize due to insufficient pressure, such as Venturi fertilizer applicators, in addition, such as power fertilizer injection pumps and water-driven piston pumps, all require additional power equipment, which requires a large investment and is not suitable for low-pressure irrigation systems; differential pressure fertilization If the pressure difference between the two ends of the valve of the tank is not well controlled, the pressure difference is too large, resulting in less water entering the system, greater water head loss, and easy precipitation of fertilizers, which affects fertilization. The adjustment of the valve for this pressure difference fertilization tank The requirements are high, the fertilizer is brought into the pipeline by the water, and the concentration of the fertilizer is difficult to control. The operator can only sense whether the fertilizer in the tank has been applied through the drain pipe, and cannot control the fertilization well
