Description

Technical Field

[0001] The utility model relates to a fertilizer tank, in particular to a centrifugal differential pressure fertilizer application device. Background Art

[0002] At present, the commonly used drip irrigation fertilizer application devices include differential pressure fertilizer tanks, venturi fertilizer applicators and fertilizer injection pumps. Among them, the differential pressure fertilizer tank has become the most widely used large-field drip irrigation fertilizer application device in the industry due to its simple structure, low cost and easy operation. It mainly consists of a tank body, a water inlet pipe, a fertilizer application pipe and a pressure regulating valve. One end of the water inlet pipe is connected to the front end of the pressure regulating valve installed on the irrigation pipeline, and the fertilizer application pipe is connected to the rear end of the pressure regulating valve. The pressure regulating valve regulates the pressure to form a pressure difference between the front and rear ends of the irrigation pipeline, and uses this pressure difference to input the fertilizer added to the tank body into the irrigation pipeline through the fertilizer application pipe for fertilizing and irrigating crops.

[0003] However, during the fertilizer application process of the existing differential pressure fertilizer tank, manual stirring of the fertilizer is required. The insufficient dissolution of the fertilizer and the resulting risk of clogging of the drip irrigation belt are important reasons that hinder its further development. At the same time, the pressure difference also affects the fertilizer application efficiency, and technical methods are needed to accelerate the dissolution of solid fertilizers and increase the fertilizer application efficiency. Summary of the Utility Model

[0004] In order to overcome the disadvantages of the prior art, the utility model provides a centrifugal differential pressure fertilizer application device. A filter pipe and a turbo fan device are installed below the fertilizer application pipe. The water inlet is used to drive the turbo fan to rotate for stirring and boosting pressure, ensuring sufficient dissolution of the fertilizer and improving the fertilizer application efficiency and uniformity.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A centrifugal differential pressure fertilizer application device, the fertilizer application device includes a fertilizer application tank body, a water inlet pipe, a fertilizer application pipe, a filter screen pipe, a turbo fan and a support leg. The upper section of the fertilizer application tank body is set as a cylinder, and the lower section is set as a cone. The water inlet pipe is tangentially connected to the cylinder on the fertilizer application tank body. The fertilizer application pipe is arranged on the top of the fertilizer application tank body. The top end of the filter screen pipe is connected to the fertilizer application pipe and is located inside the cylinder of the upper section of the fertilizer application tank body. The bottom of the filter screen pipe is connected to the turbo fan through a bearing structure. The water inlet pipe and the turbo fan are on the same horizontal plane. A fertilizer injection port and a sewage discharge port are respectively arranged at the top and bottom of the fertilizer application tank body. A sewage discharge valve is arranged on the pipeline connected to the sewage discharge port. The support leg is arranged on the outer surface of the cone of the lower section of the fertilizer application tank body.

[0007] For the above-mentioned centrifugal differential pressure fertilizer application device, the fertilizer application pipe is set as a tee structure, one end is connected to the filter screen pipe, a fertilizer application valve is arranged on one end and is connected to the irrigation system pipeline, and an exhaust valve is arranged on the other end.

[0008] In the above-mentioned centrifugal differential pressure fertilizer applicator, the bottom of the filter screen pipe is connected to the bearing, the central ring of the turbine fan is sleeved on the outer ring of the bearing, and the fan blades are evenly arranged on the central ring.

[0009] In the above-mentioned centrifugal differential pressure fertilizer applicator, a sealing cover is provided at the fertilizer injection port.

[0010] The beneficial effects of the present utility model are as follows: A pressurized centrifugal stirring structure is arranged in the fertilizer application tank body of the present utility model, that is, the combination of the filter screen pipe and the turbine fan structure. The water enters tangentially through the water inlet pipe to drive the turbine fan to rotate, thereby realizing the automatic stirring and dissolution of the fertilizer in the fertilizer application tank body, significantly improving the dissolution efficiency of the fertilizer, reducing the risk of blockage, reducing the system maintenance frequency and cost, and without manual intervention, reducing the labor intensity and saving labor costs.

[0011] The turbine fan can not only play the role of stirring and dissolving, but its rotation can also increase the pressure of the fertilizer-water mixture, ensuring that the fertilizer enters the irrigation system more efficiently through the fertilizer application pipe, improving the fertilizer application efficiency and uniformity. The tank body is designed with a cylindrical upper part and a conical lower part, combined with the layout of the filter screen pipe, effectively promoting the dissolution and separation of the fertilizer, and at the same time, the overall structure is compact, facilitating installation and maintenance.

[0017] The following further describes the present utility model in conjunction with the drawings.

[0018] Refer to Figures 1 to 3, the pressure - boosting centrifugal differential - pressure fertilizer application device of the utility model includes a fertilizer application tank body 1, a water inlet pipe 2, a fertilizer application pipe 3, a filter screen pipe 4, a turbine fan 5 and legs 6. The upper and lower ends of the fertilizer application tank body 1 are both closed. Its upper section is set as a cylinder, and its lower section is set as a cone. Water flows tangentially into the fertilizer application tank body and makes a rotational motion in the tank. The water inlet pipe 2 is tangentially connected to the cylinder of the upper section of the fertilizer application tank body 1, and a water inlet valve is arranged on the water inlet pipe. The fertilizer application pipe 3 is arranged at the top of the fertilizer application tank body 1 and is set as a tee structure. One end is connected to the filter screen pipe 4, one end is connected to the irrigation system pipeline, and a fertilizer application valve 9 is arranged on it. The other end is provided with an exhaust valve 10. The filter screen pipe 4 is located in the cylinder of the upper section of the fertilizer application tank body 1. The bottom of the filter screen pipe 4 is connected to a bearing 12, and the central ring of the turbine fan 5 is sleeved on the outer ring of the bearing. The fan blades are evenly arranged on the central ring. The water inlet pipe 2 and the turbine fan 5 are on the same horizontal plane. Water enters tangentially through the water inlet pipe. Under the action of water pressure, the turbine fan rotates. When the turbine fan rotates rapidly, it will perform reverse pressure - boosting on the fertilizer solution. The pressure above the turbine fan will increase, and the fertilizer - water mixture will be pressurized into the filter pipe, increasing the pressure of the fertilizer application pipe and improving the fertilizer application efficiency. A fertilizer injection port 7 and a sewage discharge port are respectively arranged at the top and bottom of the fertilizer application tank body 1. A sewage discharge valve 8 is arranged on the pipeline connected to the sewage discharge port, and a sealing cover 11 is also arranged at the fertilizer injection port 7. The legs 6 are arranged on the outer surface of the cone of the lower section of the fertilizer application tank body 1 to support and fix the entire fertilizer application tank body.

[0019] Working process: Fertilizer is injected into the fertilizer application tank body 1 from the fertilizer injection port 7, and the sealing cover closes the fertilizer injection port. Irrigation water enters the fertilizer application tank body 1 tangentially through the water inlet pipe, driving the fertilizer mixture in the fertilizer application tank to make a rotational motion. Under the action of centrifugal force, the fertilizer in the tank moves towards the tank wall with the water flow. At the same time, under the action of gravity, the fertilizer moves downward along the tank wall. The dissolved fertilizer - mixed clear liquid enters the fertilizer application pipe through the middle filter screen pipe and is input into the external irrigation pipeline through the fertilizer application pipe. At the same time, the water flow of the water inlet pipe jets on the fan blades of the turbine fan and drives the turbine fan to rotate rapidly. When the turbine fan rotates rapidly, it will perform reverse pressure - boosting on the fertilizer solution. The pressure above the turbine fan will increase, and the fertilizer - water mixture will be pressurized into the filter screen pipe, increasing the pressure of the fertilizer application pipe and improving the fertilizer application efficiency.
