Description

Technical Field

[0001] The invention relates to the field of static mixers, in particular to a static mixer for hydroponic cucumber breeding and a use method thereof. Background Art

[0002] Cucumber planting requires breeding in advance. In order to advance the planting season, greenhouse breeding is usually used. The seedlings after breeding are then transplanted and planted. When using greenhouse hydroponic breeding, nutrients need to be added to the hydroponic water regularly. The general way of adding nutrients is to mix the fertilizer particles with the water, and then transport the prepared nutrient solution to the culture water to achieve the effect of fertilization. However, the method of mixing first and then fertilizing increases the process, and the mixing process will waste a lot of time. Therefore, a static mixer is used to mix the fertilizer with the irrigation water. Mixing can save time. For example, the invention patent with application number CN201310624992.0 proposes a dispersed flow-around static mixer, including a cone fixed in a pipe for mixing. It has the advantages of sufficient mixing and no dead angle of flow. However, its auxiliary dissolution and mixing efficiency for fertilizer particles is low, resulting in the fertilizer particles remaining in granular form after passing through the device, resulting in poor solubility in water, affecting the uniformity of subsequent irrigation and fertilization, and general static mixers have the problem of large resistance resulting in slow flow rate, which also affects the mixing efficiency. Summary of the invention

[0010] Preferably, the cross-sectional shape of the mounting top seat is "L"-shaped, and the cross-sectional shape of the top limit ring is "7"-shaped. The control closing blade is clamped and fixed between the mounting top seat and the top limit ring. The inner side height of the bottom limit ring is higher than the outer side height. When the mounting top seat drives the control closing blade to move downward to above the bottom limit ring, the control closing blade is lifted upward by the bottom limit ring, so that the control closing blade opens upward to release the blockage on the top end of the inner sleeve.

[0011] Preferably, the outer wall of the inner sleeve is provided with a threaded groove, and the inner wall of the control sleeve is provided with a matching threaded ring, and the inner sleeve is driven to move up and down along the inner wall of the vertical pipeline by rotating the control sleeve.

[0012] Preferably, the installation positions of the lower end of the upper dispersion blade and the upper end of the lower dispersion blade are in a cross shape, and the spiral directions of the upper dispersion blade and the lower dispersion blade are opposite. The upper dispersion blade and the lower dispersion blade separate the flowing liquid twice. Through the obstruction of the upper dispersion blade and the lower dispersion blade, the liquid will first deflect counterclockwise and then clockwise during the flow inside the mixing pipe, thereby improving the effect of turbulent mixing.

[0013] Preferably, the arc-shaped flow guide cover is an arc-shaped filter plate, and the flow guide and cutting blade is spiral-shaped as a whole and is located on the inner side of the arc-shaped flow guide cover.

[0015] Preferably, the height of the left end of the cross-flow pipe is higher than that of the right end, so as to reduce the velocity of the cross-flow water during the initial irrigation and facilitate the formation of a siphon effect.

[0016] A method for using a static mixer for hydroponic cucumber breeding comprises the following steps:

[0017] S1. Close the control valve, rotate the control sleeve to drive the inner sleeve to move downward along the vertical pipe, seal the left end of the cross flow pipe through the inner sleeve, connect the water supply pipe with the water supply connecting pipe, and inject water into the water supply connecting pipe through the water supply pipe. The water fills the mixing pipe, rectifier box, heating box, concentration box and cross flow pipe;

[0018] S2. Rotate the control sleeve to drive the inner sleeve to move downward, so that the side opening is connected with the left end of the cross flow pipe, and the water inside the cross flow pipe flows into the inner sleeve through the side opening and flows downward. At this time, the filter cartridge is dragged by hand to move upward along the outer side of the control sleeve, so that the buffer diffusion cone moves upward and approaches the bottom end of the control sleeve, so that the drainage port at the bottom end of the control sleeve becomes smaller, so that the water flow inside the inner sleeve accumulates and fills the inner cavity of the inner sleeve. Then, the upper support of the filter cartridge is released, and the water inside the inner sleeve flows downward quickly to form a siphon;

[0019] S3. Add fertilizer particles into the fertilizer box. The fertilizer particles pass through the fertilizer delivery pipe downward through the water tank into the mixing pipe and then fall to the top of the upper cutting blade for the first crushing. Then, they continue to move downward until they contact the upper fitting blade on the surface of the upper dispersing blade. The fertilizer particles are crushed for the second time by the upper fitting blade. The water flow drives the fertilizer particles to flow along the surface of the upper dispersing blade and deflects in the counterclockwise direction. When the water flow and fertilizer particles flow to the lower end of the upper dispersing blade, the fertilizer particles are separated by the arc guide cover under the action of centrifugal force and move along the inner side of the arc guide cover. Finally, they contact the guide cutting blade for crushing. When the water flow flows to the connection position between the bottom end of the upper dispersing blade and the top end of the lower dispersing blade, the water flow is divided and evenly distributed again by the separation at the top end of the lower dispersing blade. The fertilizer particles contacting the lower cutting blade and the lower fitting blade are cut and crushed again. The water flow flowing to the surface of the lower dispersing blade is deflected clockwise under the restriction of the lower dispersing blade, and finally flows downward to the inside of the rectifier box for collection.

[0020] S4. The water flow entering the rectifier box continues to flow downward into the upper connecting pipe, flows downward along the upper connecting pipe, the spiral turning pipe and the lower connecting pipe, and is heated by the heating wire inside the heating box. When the water flow drives the fertilizer particles to flow along the spiral turning pipe, they will flip under the restriction of the spiral partition plate, and then the water flows downward into the concentration box. Finally, the water flows to the left through the cross flow pipe and enters the inner sleeve on the inside of the vertical pipe and flows downward to the inside of the filter cartridge. The filter cartridge blocks the fertilizer particles that are not fully broken and dissolved in the water. The blocked fertilizer particles are melted under the impact of the water flow inside the filter cartridge and are irrigated with the water body into the water body of the hydroponic cucumber seedlings.

[0021] (III) Beneficial effects

[0022] The present invention provides a static mixer for hydroponic cucumber breeding and a method for using the same. The invention has the following beneficial effects:

[0023] 1. Through the cooperation of the static mixing device and the auxiliary mixing device, the fertilizer particles in the flowing liquid collide with the multiple sets of blades inside the static mixing device, so that the fertilizer particles are cut and broken, and the flow direction of the liquid is disturbed at the same time, so that the liquid rotates clockwise first and then counterclockwise. The mixing effect is further improved by changing the flow direction, so that the fertilizer particles are fully broken and mixed with the irrigation water, thereby improving the nutrient uniformity of the nutrient solution during subsequent irrigation.

[0024] 2. When working, it mixes and discharges the nutrient solution for irrigation. At the same time, the internal liquid flow rate is increased with the siphon effect. By increasing the flow rate, the collision and crushing effect of the fertilizer particles and the blade is improved, thereby further improving the mixing and crushing effect of the fertilizer.

[0025] 3. Through the cooperation of the spiral-shaped spiral tube and the spiral partition plate, a threaded groove is opened inside the spiral tube, and the spiral partition plate itself is twisted, so that the water flow inside the spiral tube will produce a spinning flow effect. During spinning, the water in the four cavities close to the center of the spiral tube will flow along the spiral partition plate to the inner wall of the spiral tube, so that the water inside the spiral tube flows evenly to the outside and contacts the spiral tube, thereby improving the uniformity of water heating, and reducing the temperature difference between the irrigation nutrient solution and the hydroponic water by heating, preventing the cucumber seedlings from being stressed and affecting their normal growth. At the same time, the efficiency of fertilizer dissolution is also improved after heating. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Preferably, the cross-sectional shape of the mounting top seat 43 is "L"-shaped, the cross-sectional shape of the top limit ring 45 is "7"-shaped, the control closing blade 44 is clamped and fixed between the mounting top seat 43 and the top limit ring 45, the inner height of the bottom limit ring 47 is higher than the outer height, and the control closing blade 44 is fan-shaped.

[0041] In this embodiment, a thread groove is formed on the outer wall of the inner sleeve 41 , and a matching thread ring is formed on the inner wall of the control rotating sleeve 48 .

[0042] Specifically, the inner sleeve 41 is driven to move up and down along the inner wall of the vertical pipe 3 by rotating the control sleeve 48 .

[0043] In this embodiment, the installation positions of the lower end of the upper dispersing blade 71 and the upper end of the lower dispersing blade 75 are in a cross shape, and the spiral directions of the upper dispersing blade 71 and the lower dispersing blade 75 are opposite.

[0044] Specifically, the upper dispersion blades 71 and the lower dispersion blades 75 separate the flowing liquid twice. Through the obstruction of the upper dispersion blades 71 and the lower dispersion blades 75, the liquid will first deflect counterclockwise and then clockwise during the flow inside the mixing pipe 6, thereby improving the effect of turbulent mixing.

[0050] Specifically, the lateral water flow velocity is reduced during the initial irrigation to facilitate the formation of a siphon effect.

[0051] A method for using a static mixer for hydroponic cucumber breeding comprises the following steps:

[0052] S1, close the control valve 11, rotate the control sleeve 48 to drive the inner sleeve 41 to move downward along the vertical pipe 3, seal the left end of the cross flow pipe 64 through the inner sleeve 41, connect the water supply pipe with the water supply connecting pipe 2, and inject water into the water supply connecting pipe 2 through the water supply pipe, so that the water fills the mixing pipe 6, the rectifier box 61, the heating box 62, the concentration box 63 and the cross flow pipe 64;

[0053] S2, rotating the control sleeve 48 drives the inner sleeve 41 to move downward, so that the side opening 42 is connected with the left end of the cross flow pipe 64, and the water inside the cross flow pipe 64 flows into the inner sleeve 41 through the side opening 42 and flows downward. At this time, the filter cartridge 9 is dragged by hand to move upward along the outer side of the control sleeve 48, so that the buffer diffusion cone 10 moves upward and approaches the bottom end of the control sleeve 48, so that the drainage port at the bottom end of the control sleeve 48 becomes smaller, so that the water flow inside the inner sleeve 41 accumulates and fills the inner cavity of the inner sleeve 41, and then the support of the filter cartridge 9 is released, and the water inside the inner sleeve 41 flows downward quickly to form a siphon;

[0054] S3, adding fertilizer granules into the fertilizer box 5, the fertilizer granules pass through the fertilizer delivery pipe 51 downward through the water tank 1 into the mixing pipe 6, and then fall to the top of the upper cutting blade 72 for the first crushing, and then continue to move downward until it contacts the upper fitting blade 73 on the surface of the upper dispersing blade 71, and the fertilizer granules are crushed for the second time by the upper fitting blade 73. The water flow drives the fertilizer granules to flow along the surface of the upper dispersing blade 71 and deflects in the counterclockwise direction. When the water flow and the fertilizer granules flow to the lower end of the upper dispersing blade 71, the fertilizer granules are centrifuged. The water particles are separated by the arc-shaped guide cover 74 and move along the inner side of the arc-shaped guide cover 74, and finally contact the guide cutting blade 78 to be broken. When the water flows to the connection position between the bottom end of the upper dispersing blade 71 and the top end of the lower dispersing blade 75, the water flow is divided and evenly distributed again by the separation at the top end of the lower dispersing blade 75. The fertilizer particles contacting the lower cutting blade 76 and the lower fitting blade 77 are cut and broken again. The water flow flowing to the surface of the lower dispersing blade 75 is deflected clockwise under the restriction of the lower dispersing blade 75, and finally flows downward to the inside of the rectifier box 61 to be collected.

[0055] S4. The water flow entering the rectifier box 61 continues to flow downward into the upper connecting pipe 82, and flows downward along the upper connecting pipe 82, the spiral turning pipe 81 and the lower connecting pipe 83. At the same time, it is heated by the heating wire inside the heating box 62, and the water flow drives the fertilizer particles to flow along the spiral turning pipe 81. When it is restricted by the spiral partition plate 85, the water flows downward into the concentration box 63. Finally, the water flows to the left through the cross flow pipe 64 and enters the inner sleeve 41 on the inner side of the vertical pipe 3 and flows downward to the inside of the filter cartridge 9. The filter cartridge 9 blocks the fertilizer particles that are not fully broken and dissolved in the water. The blocked fertilizer particles are melted under the impact of the water flow inside the filter cartridge 9 and are irrigated into the water body of the hydroponic cucumber seedlings with the water body.

[0056] The working principle and use process of the present invention are as follows: the device is erected above the hydroponic box through an external bracket, so that the filter cartridge 9 is located above the hydroponic box, and the water supply pipe is connected to the water supply connection pipe 2. When it is necessary to directly irrigate and replenish water, the control valve 11 is opened, and the control sleeve 48 is rotated to drive the inner sleeve 41 to move downward along the inside of the vertical pipe 3. The left end of the cross flow pipe 64 is sealed by the inner sleeve 41, so that the water added to the inside of the water tank 1 can directly flow downward through the vertical pipe 3 into the inside of the inner sleeve 41, and finally flow downward into the inside of the filter cartridge 9 and be discharged outward for water replenishment. When it is necessary to supplement nutrients in the water body, the control valve 11 is closed, and the control sleeve 48 is rotated to drive the inner sleeve 41 to move upward, so that the inner sleeve 41 drives the side opening 42 The left end of the cross flow pipe 64 is connected, and the water inside the cross flow pipe 64 flows into the inner sleeve 41 through the side opening 42 and flows downward. At this time, the filter cartridge 9 is dragged by hand to move upward along the outer side of the control rotating sleeve 48, so that the buffer diffusion cone 10 moves upward and approaches the bottom end of the control rotating sleeve 48, so that the drainage port at the bottom end of the control rotating sleeve 48 becomes smaller, so that the water flow inside the inner sleeve 41 is accumulated, and the internal cavity of the inner sleeve 41 is filled with water, and then the upper support of the filter cartridge 9 is released, and the water body inside the inner sleeve 41 flows downward rapidly to form a siphon, and the fertilizer particles are added to the inside of the fertilizer box 5. The fertilizer particles pass through the fertilizer delivery pipe 51 downward through the water tank 1 into the inside of the mixing pipe 6, and then fall to the top of the upper cutting blade 72 for the first crushing, and then continue to move downward to The upper fitting blade 73 contacts the surface of the upper dispersing blade 71, and the fertilizer particles are crushed for the second time by the upper fitting blade 73. The water flow drives the fertilizer particles to flow along the surface of the upper dispersing blade 71 and deflects in the counterclockwise direction. When the water flow and the fertilizer particles flow to the lower end of the upper dispersing blade 71, the fertilizer particles are separated by the arc guide cover 74 under the action of centrifugal force and move along the inner side of the arc guide cover 74, and finally contact the guide cutting blade 78 for crushing. When the water flow flows to the connection position between the bottom end of the upper dispersing blade 71 and the top end of the lower dispersing blade 75, the water flow is divided and evenly divided again by the separation at the top end of the lower dispersing blade 75, and the fertilizer particles contacting the lower cutting blade 76 and the lower fitting blade 77 are cut and crushed again, and flow to the lower dispersing blade The water flow on the surface of 75 is deflected clockwise under the restriction of the lower dispersion blade 75, and finally flows downward to the inside of the rectifying box 61 for collection. The water flow entering the rectifying box 61 continues to flow downward into the upper connecting pipe 82, and flows downward along the upper connecting pipe 82, the spiral turning pipe 81 and the lower connecting pipe 83. At the same time, it is heated by the heating wire inside the heating box 62. The water flow inside the spiral turning pipe 81 will produce a spinning flow effect. During the spinning, the water body at the center of the spiral turning pipe 81 in the four cavities separated by the spiral dividing plate 85 will flow along the spiral dividing plate 85 to the inner wall of the spiral turning pipe 81, so that the water body inside the spiral turning pipe 81 flows evenly to the outside and contacts with the spiral turning pipe 81, thereby improving the uniformity of water heating.And by heating, the temperature difference between the irrigating nutrient solution and the hydroponic water body is reduced to prevent the cucumber seedlings from being stressed and affecting their normal growth. At the same time, the efficiency of fertilizer dissolution is also improved after heating. Then the water flows downward into the interior of the concentration box 63, and finally the water flows to the left through the cross-flow pipe 64 into the interior of the inner sleeve 41 inside the vertical pipe 3 and flows downward to the interior of the filter cartridge 9. The filter cartridge 9 blocks the fertilizer particles that are not fully broken and dissolved in the water. The blocked fertilizer particles are melted under the impact of the water flow inside the filter cartridge 9 and then irrigated into the water body of the hydroponic cucumber seedlings with the water body. The water flow contacts the buffer diffusion cone 10 and diffuses outward for buffering, reducing the impact force of the discharged water flow.

7. A method for using a static mixer for hydroponic cucumber breeding, comprising the static mixer for hydroponic cucumber breeding according to claim 1, characterized in that: The following steps are involved: S1. Close the control valve (11), rotate the control sleeve (48) to drive the inner sleeve (41) to move downward along the inside of the vertical pipe (3), seal the left end of the cross flow pipe (64) through the inner sleeve (41), connect the water supply pipe with the water supply connecting pipe (2), and inject water into the water supply connecting pipe (2) through the water supply pipe, so that the water fills the mixing pipe (6), the rectifier box (61), the heating box (62), the concentration box (63) and the cross flow pipe (64); S2. The control sleeve (48) is rotated to drive the inner sleeve (41) to move downward, so that the side opening (42) is connected to the left end of the cross flow pipe (64), and the water in the cross flow pipe (64) flows into the inner sleeve (41) through the side opening (42) and flows downward. At this time, the filter cartridge (9) is dragged by hand to move upward along the outer side of the control sleeve (48), so that the buffer diffusion cone (10) moves upward and approaches the bottom end of the control sleeve (48), so that the drainage port at the bottom end of the control sleeve (48) becomes smaller, so that the water flow inside the inner sleeve (41) is accumulated and the internal cavity of the inner sleeve (41) is filled. Then, the support of the filter cartridge (9) is released, and the water inside the inner sleeve (41) flows downward quickly to form a siphon; S3. Fertilizer particles are added to the interior of the fertilizer box (5). The fertilizer particles pass through the fertilizer delivery pipe (51) downward through the water tank (1) into the interior of the mixing pipe (6) and then fall to the top of the upper cutting blade (72) for the first crushing. The particles then continue to move downward until they come into contact with the upper fitting blade (73) on the surface of the upper dispersing blade (71). The fertilizer particles are crushed for the second time by the upper fitting blade (73). The water flow drives the fertilizer particles to flow along the surface of the upper dispersing blade (71) and deflect in a counterclockwise direction. When the water flow and the fertilizer particles flow to the lower end of the upper dispersing blade (71), the fertilizer particles are crushed by the centrifugal force. Under the action of the curved guide cover (74), the water is separated and moves along the inner side of the curved guide cover (74), and finally contacts the guide cutting blade (78) to be broken. When the water flows to the connection position between the bottom end of the upper dispersing blade (71) and the top end of the lower dispersing blade (75), the water flow is again separated and evenly divided by the separation at the top end of the lower dispersing blade (75). The fertilizer particles contacting the lower cutting blade (76) and the lower fitting blade (77) are cut and broken again. The water flow flowing to the surface of the lower dispersing blade (75) is deflected clockwise under the restriction of the lower dispersing blade (75), and finally flows downward to the inside of the rectifier box (61) to be collected. S4. The water flow entering the rectifying box (61) continues to flow downward into the upper connecting pipe (82), flows downward along the upper connecting pipe (82), the spiral turning pipe (81) and the lower connecting pipe (83), and is heated by the heating wire inside the heating box (62). The water flow drives the fertilizer particles to flow along the spiral turning pipe (81), and the fertilizer particles are turned under the restriction of the spiral partition plate (85). Then the water flows downward into the concentration box (63). Finally, the water flows to the left through the cross flow pipe (64) and enters the inner sleeve (41) inside the vertical pipe (3) and flows downward into the filter cartridge (9). The filter cartridge (9) blocks the fertilizer particles that are not fully broken and dissolved in the water. The blocked fertilizer particles are melted under the impact of the water flow inside the filter cartridge (9) and are irrigated into the water body of the hydroponic cucumber seedlings.
