Description

A fertilization tank for a micro-irrigation system

technical field

The utility model belongs to irrigation equipment, in particular to a micro-irrigation system fertilization tank.

Background technique

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.

Contents of the invention

The purpose of the utility model is to provide a micro-irrigation system fertilization tank with good fertilization effect and easy control. The technical solution of the utility model to solve the technical problem is to include a fertilization tank, which is characterized in that: the upper part of one side of the fertilization tank is provided with a glass tube, one end of the outlet pipe is connected to the upper port of the glass tube, and the other end of the outlet pipe One end is connected to the water outlet end of the fertilization valve on the pipeline of the micro-irrigation system. The water inlet pipe is placed in the fertilization tank. The upper end of the water inlet pipe is connected to the water inlet end of the fertilization valve. The above water inlet pipe and the water outlet pipe are each provided with a valve. A floating ball with a specific gravity greater than water is placed in the inverted cone hole in the above glass tube. The glass tube is provided with a scale line indicating the position of the floating ball, and an exhaust valve is provided at the bottom of the glass tube. The water outlet of the water inlet pipe is placed at the center of the bottom of the fertilization tank and is not in contact with the bottom of the fertilization tank. Compared with the prior art, the utility model has the remarkable advantages of uniform fertilization, good effect and easy operation.

Detailed ways

The utility model is described in detail in conjunction with the following embodiments, the two ends of the fertilization valve 2 on the pipeline 1 of the micro-irrigation system are respectively connected with a water inlet pipe 5 and a fertilizer liquid pipe 6, wherein the water inlet pipe 5 passes into the fertilization tank 10 At the bottom of the tank, the fertilizer liquid pipe is connected to the upper port of the glass tube 8 outside the upper part of the fertilization tank. In the inverted tapered hole of glass tube, the specific gravity of this floating ball is greater than the specific gravity of water, and it can be made of metal, respectively be provided with valve 3,4 on the above-mentioned water inlet pipe 5 and fertilizer liquid pipe 6, the top of fertilization tank is provided with. There is a fertilizer injection port sealing cover (the known structure on the existing fertilization tank). In order to prevent the residue in the fertilizer solution from clogging the sprinkler, a filter needs to be installed on the pipeline 1 at the water outlet of the fertilization valve.

The working principle and operation method of the utility model are as follows: pour quantitative fertilizer into the fertilization tank through the fertilization port on the top of the fertilization tank and seal the fertilization port, open the valve 3 and close the valve 2 to make the water on the pipeline Fully flow into the fertilization tank and gradually fill the fertilization tank with water, so that the fertilizer is gradually dissolved by water, and then open the valve 4 to deliver the fertilizer solution to the pipeline and send it to the capillary tube in the field to deliver the fertilizer solution to the plant roots. The working principle of the utility model is, through the adjustment of the fertilization valve 2 on the pipeline to make the pressure difference at both ends, part of the water is diverted into the fertilization tank and the fertilizer liquid is sent into the pipeline. When the concentration of the fertilizer solution in the fertilization tank increases beyond the set value, the floating ball will move up to above the set scale line. At this time, the adjustment valve 2 will increase the amount of water entering the fertilization tank, the concentration of the fertilizer solution will decrease, and the float will drop. until it returns to the set scale line. The concentration of the fertilizer liquid drops, the floating ball moves down, and the reverse adjustment valve 2 makes it reach the set concentration value. When the fertilizer is completely dissolved, the floating ball is greater than the specific gravity of the water and drops to block the inverted cone hole of the glass tube, indicating that the fertilizer is used. At this time, the valves 3 and 4 can be closed, and the fertilization valve can be fully opened. The utility model has the advantages of adjustable fertilizer concentration, uniform fertilization and no need for external power equipment. At the same time, the outlet of the water inlet pipe is arranged at the bottom of the fertilization tank, which has the advantages of preventing waste from being completely dissolved at the bottom of the tank.
