A hydraulic self-adaptive dynamic water and fertilizer mixed rectifier regulator and method

Abstract

The present invention is based on the structure of static mixer blades commonly used in water and fertilizer blending, and clockwise and counterclockwise actuators are arranged inside adjacent blades, so that the relative positions of adjacent blades can be adjusted according to the flow velocity and pressure, thereby increasing the fertilizer liquid mixing process. Stability; the inner counterclockwise mixing blade and the inner clockwise mixing blade are used in conjunction with the adjustment mechanism and the blade installation shaft to achieve the continuous compression and expansion of the water and fertilizer mixing liquid, which increases the mixing time of water and fertilizer and improves the blending of water and fertilizer. It can adapt to the water and fertilizer mixing conditions of different flow rates and pressures, and can meet the irrigation needs of various types of crops in different growth periods and different water and fertilizers. It can effectively reduce the variation of water flow and pressure, and make the water and fertilizer mixture in the irrigation pipeline The pressure remains stable, the water and fertilizer are mixed evenly, the self-adaptation is strong, and the structure is simple. It can not only be installed in large-scale irrigation water and fertilizer machine equipment, but also suitable for the use and promotion of large-scale water and fertilizer integrated irrigation.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation, and relates to a voltage stabilizer suitable for a water-fertilizer irrigation integrated machine with a large irrigation area, multi-channel fertilizer supply and irrigation water, in particular a hydraulic self-adaptive dynamic water-fertilizer mixing rectifier voltage stabilizer and methods. Background technique [0002] my country is a large agricultural country, and agricultural water consumption accounts for 80% of the total water consumption, and the vast majority of agricultural water consumption is used for crop irrigation. However, the irrigation equipment in our country is far behind that of developed countries. The shortage of water resources has seriously affected the healthy development of local industry and agriculture, and also affected the safety of domestic water in local cities. Water and fertilizer integration technology is a new agricultural technology that i...

Problems solved by technology

In the process of mixing fertilizer and liquid, most of them use active fertilizer injection, venturi or proportional fertilization pump for passive fertilizer absorption. These methods have their own advantages and disadvantages. For most irrigation, it depends on the different growth stages of the crops. According to the needs of different types of fertilizers, the integrated irrigation of water and fertilizers is carried out. Therefore, the method commonly used at home and abroad is to supply different types of fertilizers through multiple channels. The fertilizers mainly include N, P and K fertilizers, which are in large demand and Ca, Composed of trace elements such as Mg, in the irrigation of the water and fertilizer integrated machine, since the multi-channel fertilizer pipeline injects fertilizer into the main waterway during the fertilizer injection process, it is easy to cause the instability of the pipeline water pressure and flow rate

At present, static mixers are mostly used for mixing various types of fertilizers. The blades of the mixers are fixed. During the process of water and fertilizer blending, there is no feedback for changes in pipeline water pressure and flow rate. When the flow rate is relatively stable, the effect of water and fertilizer blending is better, but for the state of poor water pressure and flow rate stability, the effect of water and fertilizer blending is poor. When the irrigation area is large, it is easy to cause poor uniformity of irrigation and fertilization, affecting crop yield and quality

[0004] At present, related patents related to dynamic mixers include: Dynamic mixer (2015100478889), the device fluid passes through the gap between the end of the raised structure and the inner wall of the outer sleeve, and the formation of an axially stretched flow field is beneficial to improve The mixing efficiency of the melt, but this device is suitable for the fusion of the melt, the flow rate of the fusion process of water and fertilizer is relatively large, and the flow rate of this dynamic mixer is small, which is not suitable for the process of water and fertilizer fusion; a double cone dynamic mixer (201510205055.0), the device, through the cooperation of the east piece and the static piece set on Tongzhou, the flow channel of the stroke cone, is beneficial to extend the length of the flow channel, and the shear force on the fluid is large, but in this mixed flow process, For a variety of large elements, the ability to quickly and uniformly mix is ​​limited, the processing cost of the biconical surface is high, and the applicability of the device is limited; the dynamic mixer and its use (2012800107296), the device is applied to the dynamic mixing of multiple fluid components, Although it is suitable for the mixing of multi-channel fertilizers and waterways, the structure of the device is complex, the comprehensive feedback ability of fluid pressure and flow rate is limited, and the cost is high. The production input capacity of farmers in our country is limited, and the use of this device increases the burden of agricultural production.
