Technical Field
The utility model belongs to the technical field of liquid manure integration irrigation equipment, especially, relate to an improve venturi uniform fertilizing device of choke negative pressure.
Background
At present, the water and fertilizer integrated fertilization modes adopted at home and abroad mainly comprise two modes: the additional power injection mode and the differential pressure injection mode of the high-pressure water power of the sprinkler irrigation system are adopted, wherein the additional power injection mode pumps the fertilizer liquid into the main pipeline in an additional pump mode, the mode is convenient and quick, the fertilizer is uniformly applied, but the equipment is expensive and the maintenance is difficult; the device for forming the pressure difference in the pressure difference injection mode mainly comprises three types of series-parallel venturi tubes, valve ports or pitot tubes, wherein the mode of adopting the parallel venturi tubes has simple structure and low cost, and is an ideal pressure difference device in the three modes for forming the pressure difference.
The principle of venturi fertilizer absorber work is that rivers through one by big gradually little by little when the pipeline that grows gradually again (venturi throat), because rivers flow rate increases when narrow portion, pressure drop, forms pressure differential around making, when the throat has the entry of a less pipe diameter, forms the negative pressure, utilizes the pressure differential between external atmospheric pressure and the throat negative pressure, inhales fertilizer solution from open fertilizer jar in through the small pipe diameter and inhales irrigation system.
But the venturi fertilizer sucker has the following defects in use: (1) the venturi tube is required to realize natural fertilizer suction, and the sufficient difference between the inlet pressure and the outlet pressure is ensured, so that water is spouted instead of fertilizer suction when the pressure difference is small, and the problem that the normal fertilizer suction cannot be realized due to insufficient negative pressure of the throat tube can occur in the fertilizer suction process. (2) The venturi fertilizer suction device is sensitive to pressure and flow changes during working, and the changes of the operating conditions of the venturi fertilizer suction device can cause fluctuation of water-fertilizer ratio, so that the fertilizer application is not uniform. (3) In water-saving irrigation, peasant household generally uses sprinkling irrigation and burette dual mode, and wherein the burette is owing to block up the dripper easily, arrange loaded down with trivial details, generally difficult peasant household accepted, and little sprinkling irrigation area is because low price lays and is used by peasant household extensively easily, nevertheless the sprinkling irrigation area will make the water column have certain height, must the end tie tightly, can cause rivers to be obstructed like this, venturi advances, outlet pressure differential diminishes, can't obtain using in the sprinkling irrigation area.
