The utility model relates to a theory of operation of water conservancy formula self-adaptation developments liquid manure mixed rectification stabiliser is: in the large-area water and fertilizer integrated irrigation, N elements, P fertilizers, K fertilizers and trace elements through multi-branch fertilizer pipelines enter an irrigation water main pipeline in an active fertilizer injection or passive fertilizer suction mode, and uneven water and fertilizer mixed liquid is formed through preliminary mixing.
As shown in fig. 18, uneven water and fertilizer mixed liquid enters the mixer from the water inlet joint 11 of the irrigation main pipeline entering device, and when the water and fertilizer mixed liquid enters the mixer at the initial stage, axial forces of the water outlet end spring 4 and the water inlet end spring 8 at two ends of the blade mounting shaft 22 are equal, so that the tensile force of the pre-tightening spring 19 inside the adjacent inner anticlockwise mixing blade 5 and the inner clockwise mixing blade 6 and the tensile force of the cylindrical convex column 23 on the blade mounting shaft 22 and the inner anticlockwise spiral channel 14 and the inner clockwise spiral channel 16 inside the blade are equal, and the adjacent inner anticlockwise mixing blade 5 and the inner clockwise mixing blade 6 are in a relative vertical relationship. At the moment, the liquid-fertilizer mixed liquid flows around the two sides of the inner clockwise mixing blade 6 in two ways, then enters the two sides of the inner anticlockwise mixing blade 5 vertical to the liquid-fertilizer mixed liquid, and is mixed with the liquid-fertilizer through different blades in sequence.
When the liquid fertilizer mixture enters the device, the internal pressure is gradually increased, and the liquid fertilizer mixture starts to enter a cavity formed by the blade adjuster seat 20, the blade adjusting actuator 18 and the blade adjuster mounting outer hole 13 through the blade pressure adjusting channel 12 under the action of pressure. Because the pre-tightening spring 19 is in a stretching state, the pressure inside the cavity is gradually increased along with the continuous entering of the water-fertilizer mixed liquid into the cavity under the condition of pressure variation, and when the pressure of the cavity is greater than the tension of the pre-tightening spring 19, the blade adjusting and executing part 18 moves along the axial direction. Because the cylindrical boss 23 provided on the vane mounting shaft 22 is not changed in position relative to the vane mounting shaft 22, the axial movement of the vane adjusting actuator 18 causes the inner counterclockwise mixing vane 5 to move axially in the other direction of the axial movement of the vane adjusting actuator 18 under the cooperation and guidance of the cylindrical boss 23 on the vane mounting shaft 22 and the inner counterclockwise helical channel 14. During the movement, the inner anticlockwise mixing blade 5 rotates a certain angle in the radial direction due to the action of the cylindrical convex column 23 and the inner anticlockwise spiral channel 14. The helical channels inside the inner counter-clockwise and inner- counter-clockwise mixing blades 5, 6 are inner counter-clockwise helical channels 14, 16, respectively, so that for the inner-clockwise mixing blade 6, due to the increased water pressure adjacent to the inner counter-clockwise mixing blade 5 and entering its cavity, there is also an axial movement in the other direction of the axial movement of the blade adjustment actuator 18, but unlike the inner counter-clockwise mixing blade 5, the inner-clockwise mixing blade 6 is rotated in the opposite radial direction to the inner counter-clockwise mixing blade 5.
As shown in fig. 19, the inner clockwise mixing blades 6 and the inner counterclockwise mixing blades 5 are opposite in radial rotation direction in case of water pressure variation, the two blades are changed from the original mutually vertical state to the non-vertical state, which is equivalent to that the liquid manure mixed liquid firstly passes through the inner clockwise mixing blade 6 to be divided into two parts to flow around, when the two parts flow through the inner clockwise mixing blade 6 and enter the range of the inner anticlockwise mixing blade 5, one part of the mixed volume on the inner anticlockwise mixing blade 5 is reduced and compressed, and the mixed liquid of the other part expands due to the volume increase, and the two parts of mixed liquid pass through the inner anticlockwise mixing blades 5 and enter the range of the next inner clockwise mixing blade 6, the compressed portion of the fluid becomes less pressurized due to the increased volume and the expanded portion of the fluid becomes more pressurized due to the decreased volume, thus reciprocating into the next mixing blade. In the mixing process, because the fluid is constantly compressed and expanded, so the process of melting mutually of water and fertilizer has been accelerated, improves mixing efficiency, simultaneously, can carry out the rectification to the liquid manure mixed liquid of entering device for the mixed liquid pressure variation through the device reduces, has improved the velocity of flow and the pressure in the liquid manure irrigation process and has kept stable.
While the present invention has been particularly shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
