It is to be understood that the first to second aspects described in the present specification are merely referred to in order to distinguish between different components and are not limited to the order in which they are manufactured, It may not match.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1, the powder liquid injection system according to the present invention includes a high-pressure pump 10, an ejector 20, a hopper 30, and an injector 50 as shown in FIG. An auxiliary pipe 65 capable of supplying the liquid supplied from the high-pressure pump 10 and a flocculant 70 to the ejector 20 (in the middle) while the loess powder is supplied from the hopper 30 to the ejector 20 And a coagulant supply pipe 75 for supplying the coagulant to the downstream side.

The high-pressure pump 10 sucks the liquid 200 stored in the liquid storage part 300 at a high pressure and supplies the liquid 200 to the ejector 20. The term "high pressure" in the present specification does not mean a pressure higher than a certain specific pressure, but liquid in the injection system according to the present invention is passed through the ejector 20, mixed with the loess powder supplied from the hopper 30, The present invention is not limited to the above-described embodiments. Although the present invention has been described in detail with reference to specific embodiments thereof, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention. It is obvious that it does not interfere.

The liquid storage unit 300 may be separately provided, but usually means a natural storage unit such as a sea, a lake, a river, or the like. The liquid 200 may be seawater, river or the like. The high-pressure pump 10 should not be construed to be limited to a specific pressure range which means that the pressure of the liquid to be discharged is higher than the pressure of the suction liquid.

 The ejector 20 is a mechanical device for mixing liquids. The liquid 200 that has entered the direction A passes through nozzles in the ejector 20 to perform a high-speed flow. At this time, The ocher powder 100 of the hopper 30 is supplied in the direction B and mixed with the liquid so as to come out of the ejector 20 and flow along the supply pipe 60. The pressure in the ejector 20 drops and a negative pressure is applied so that the loess powder of the hopper 30 can be easily fed into the ejector 20 through the loess powder feed amount adjusting device 40 (to be described later).

The ejector 20 will be described in more detail with reference to an enlarged view of FIG. 1 is an enlarged cross-sectional view showing the ejector 20 of the present invention.

1, the ejector 20 includes an inlet 24 connected to the liquid reservoir 300 to receive liquid from the high-pressure pump 10, a mixing unit 22 connected to the inlet, A supply nozzle 21 connected to the inlet port 24 to be connected to the mixing section 22 and a diffusion section 23 connected to the inlet port 24 to receive the powder liquid from the connection port 23, (25)

The ejector 20 uses a venturi effect and can easily receive the loess powder 100 from the hopper 30 by using a change in velocity and pressure of the liquid.

The supply nozzle 21 of the ejector is formed in such a form that the cross-sectional area decreases toward the A direction. The liquid is injected into the mixing portion 22 through the supply nozzle 21. At this time, the liquid passing through the supply nozzle 21 is converted into velocity energy by the pressure energy and is jetted at high speed.

Therefore, the pressure in the mixing section 22 drops to a very low pressure, and the loess powder and a flocculating agent to be described later are supplied through the supply pipes 41 and 75 connected to the mixing section 22 due to the low pressure inside .

The loess powder and the coagulant supplied due to the high-speed injected liquid and the pressure difference through the supply nozzle 21 are transferred and mixed together through the mixing portion 22 and the connecting portion 23 according to the Bernoulli principle, Compressed and discharged through a diffusion portion 25 into a powder liquid supply pipe 55 connected to the injection device.

This makes it possible to smoothly supply the loess powder by using the Venturi effect through the Bernoulli theorem, to increase the mixing efficiency with the liquid introduced from the liquid storage part, and to ensure the discharge pressure for reaching the powder liquid to the spray device to be.

1, the powder liquid injection system according to the present invention further includes a flocculant storage tank and a flocculant supply pipe 75 connected to the ejector and supplying the flocculant 70 to the downstream side of the ejector 20 .

A flocculant storage tank for supplying the flocculant 70 to the downstream side of the ejector 20 is provided. By supplying the flocculant to the liquid discharged from the ejector 20 mixed with the loess powder, The sedimentation efficiency can be increased by shortening the sedimentation time of algae such as greenhouse. As the coagulant (70), HiBPAHCS2020 or HiBPAHCS2500, which are products sold by Sanko Chemical Co., Ltd., can be used.

The hopper 30 serves as a reservoir for storing the loess powder 100 and a powder supply amount regulating device 40 is provided between the hopper 30 and the ejector 20. The powder is supplied into the mixing portion of the ejector 20 in the direction B by an amount specified by the powder feed amount regulating device 40. [ It should be understood that the powder may be a loess powder or the like and covers other types of powders in addition to the loess according to the application of the present invention.

As shown in FIG. 2, the hopper 30 may further include stirring means. Fine loess particles have mutual stenosis properties, so that in a butttle neck under the hopper, loess may be leviated only at the upper part like a tunnel. In this case, the suction force due to the vacuum pressure of the ejector 20 is not sufficient, so that the yellow soil may not be sucked. Therefore, when the very fine loess of the particles is used, the hopper 30 is provided with the vibration generator 31, and the inside of the hopper, that is, adjacent to the bottle neck, It is preferable to act as stirring means.

Vibrations generated by the vibration generator 31 installed in contact with the hopper 30 or the vibrating element 32 generate vibration in the hopper 30 to prevent mutual constriction of the yellowing powder, The vibration transmitted to the piece 32 can secondarily break the balance state of the levitated yellow soil mentioned above and smooth the supply of the powder to the ejector.

Further, the hopper 30 may further include a vibrating rod (not shown) connected to the vibration generator and vertically penetrating the bottle neck of the hopper. The vibrating rod also functions as a stirring means like the above-mentioned vibrating piece, and it is possible to supply the powder to the ejector 20 smoothly.

1, the pressure loss in the injector 50 may be reduced due to a considerable pressure loss occurring in the ejector 20. In this case, The capacity of the ejector 20 can be reduced by providing the supply amount regulating device 40 and the pressure loss can also be reduced due to the reduction of the capacity of the ejector 20. [

The loess powder feed amount adjustment device 40 preferably has a structure in which an electric gear device (not shown) is provided therein to supply the loess powder of the hopper 30 to the ejector 20 by driving the gear device, The amount of the loess powder supplied per hour can be adjusted as desired by the user.

According to another embodiment of the present invention, a manual control valve may be provided in place of the loess powder feed amount adjusting device 40 using the electric gear device to adjust the loess powder feed amount. This manual regulating valve has an effect of preventing the liquid from flowing back toward the hopper 30 at the time of stoppage of the injection system because the supply of the manual regulating valve can be blocked completely, that is, the outlet of the hopper 30 can be blocked .

In another embodiment according to the present invention, the powder supply amount regulating device 40 may further include a sliding valve 42 together with the manual regulating valve so as to constitute a double supply valve (see the upper enlarged view of FIG. 1) ).

First, the manual control valve may be composed of a ball valve 41 having the lowest flow efficiency among the various valves with the least amount of interim shutoff. In the case where the valve position of the ball valve 41 is in an intermediate state, it is difficult to adjust the flow amount (supply amount) with respect to the powder flow, A separate sliding valve 42 is added to the upper part of the ball valve 41 to quantitatively control the amount of powder to be supplied to the ball valve 41. The ball valve 41 is connected to the hopper 41, (I.e., ON / OFF) only.

Since the ball valve 41 and the sliding valve 42 are easily obtainable as an average descriptor in the field to which this technology belongs, and the configuration thereof is well known, a detailed description thereof will be omitted.

Meanwhile, the hopper 30 is preferably detachably connected to the ejector 20 at the separation boundary 35. The separation boundary 35 is provided between the loess powder feed regulator 40 and the hopper 30 and may be provided between the loess powder feed regulator 40 and the ejector 20 . The hopper 30 may be detachably attached to the separating boundary 35 in a bolt-nut manner, or may be detachably coupled in a manner such as threaded engagement or the like, and various methods widely known to those skilled in the art And the scope of rights of the present invention should not be construed as being limited to such a fastening method.

When the hopper 30 is detachably provided at the separating boundary line 35, it is possible to separate the hopper 30 and facilitate the cleaning of the discharge port when the yellow clay powder clogs the discharge port of the hopper 30 in the course of supplying the loess powder Advantages are provided.

There is provided an auxiliary pipe 65 for supplying the liquid 200 on the way upstream of the ejector 20 from the liquid supply source 60 and on the middle of the supply of the loess powder from the hopper to the ejector 20.

Since the liquid 200 is supplied between the hopper 30 and the ejector 20 through the auxiliary pipe 65, the loess powder 100 is supplied between the hopper 30 and the ejector 20, The clogging phenomenon can be prevented.

Further, the auxiliary pipe 65 can prevent clogging of the loess powder 100 through the ejector 20 using the venturi effect described above, so that it can be omitted in the present invention.

The yellow loose powder liquid mixed with the loess powder 100 in the ejector 20 is supplied to the spraying apparatus 50 along the supply line 55. Here, the loess powder is a mixture of a liquid and a loess powder. The loess powder includes a mixture in which the powder is sprayed together with the liquid even when the powder is not completely dissolved or completely dissolved in the liquid, .

The controller 51 and the operating unit 53 are connected to the injector 50. When the user selects the injection speed, the direction and the injection amount through the operating unit 53, the controller 51 controls the injector 50) so that the loess powder liquid can be sprayed as desired.

However, when the loess is sprayed on the surface, the specific gravity of the loess is higher than that of the water, so it sinks vertically and settles on the floor. Therefore, in order to increase the algae elimination effect of loess, it is necessary to lengthen the staying time of the loess powder in the water as possible and to create an environment in which the algae can be adsorbed by mixing (mixing and mixing).

To this end, the powder liquid spraying system according to the present invention is provided with components such as the high-pressure pump 10, the hopper 30, the ejector 20 and the spraying device 50 on the main line, ) Can be additionally provided.

3 is a perspective view showing a second embodiment of the injection system according to the present invention. As shown in FIG. 3, the blending means includes a plurality of plotters 3A coupled together to secure a floating force, and a plotter longitudinal line 3 capable of self-propelling can be formed by mounting a propeller 57 or the like. have.

The plotter vertical line 3 is formed by a plurality of plotters 3A coupled to each other. Although FIG. 3 shows a second embodiment in which eight plotters are combined to form a square shape, the number and shape of the floaters 3A forming the plotter vertical line 3 are not limited by the present specification.

Since the plurality of plotters 3A are coupled to each other, the plotter vertical line 3 may further include coupling means for coupling the floaters 3A. The coupling means may be a separate member to forcefully constrain each of the floaters, but may also be coupled to each other with coupling means on the floats themselves.

3, the plotter 3A has an engaging projection 3a serving as a male thread on one side thereof, and an engaging projection 3a on the other side thereof. And an engaging groove 3b to which the engaging projection 3a is engaged. As described above, the plotter vertical line 3 shown in Fig. 3 is an embodiment for convenience of explanation, and the present invention is not limited thereto. If the plotter 3A is fixedly coupled to each other and the floating force can be ensured, No restraint. In FIG. 3, each of the plotters 3A is provided with a coupling means composed of coupling protrusions and coupling grooves, respectively. However, the present invention is not limited thereto. Furthermore, it is preferable to provide a plurality of coupling means so that the plotters 3A can be combined with each other in a desired form so that the plotter vertical line 3 can be formed.

Further, the plotter longitudinal line 3 of the present invention can have a propeller 57 for allowing the powder liquid to be mixed while allowing the self-discharge. Therefore, the propeller 57 provided on the bottom surface of the plotter longitudinal line 3 is formed to be spaced apart from the bottom surface by a predetermined distance, unlike a conventional small ship.

As described above, in order to enhance the algae removing effect, the present invention preferably generates a vortex at a deep water depth through a propeller 57 formed at a predetermined distance in the vertical direction from the bottom surface of the plotter longitudinal line 3.

The expression that the propeller 57 is formed with a predetermined distance is expressed as an optimum depth of water capable of maximizing the algae elimination effect by mixing the powder liquid through the vortex, A person skilled in the art can predict the depth of the water well and adjust the optimum gap between the bottom surface of the plotter vertical line 3 and the flowplayer, so that the present invention is not limited thereto.

Therefore, it is preferable that the propeller 57 is formed so as to adjust the bottom surface and depth and position of the plotter longitudinal line 3 in order to adjust the distance between the plotter longitudinal line 3 and the propeller 57. Further, it is more preferable that the size and number of the propeller 57 are not limited, and that the propeller 57 is formed by appropriately sizing or numbering a person skilled in the art to mix the powder liquid and maximize the algae removing effect Do.

The powder liquid injected by the injector 50 mounted on the main line precipitates at the water surface to cause algae removing action. The powder liquid is injected through a vortex generated in water by the propeller 57 of the plotter vertical line 3, It can be mixed with seawater or fresh water of the target area (sea or lake) to increase the water retention time and increase the algae removal time.

Further, as shown in FIG. 4, the powder liquid system according to the present invention is a third embodiment, and the mixing means can be constituted by a ship type self-contained vertical line 2. As shown in FIG. 4, the vertical line 2 is made of FRP (Glass Fiber Reinforced Plastic) and is an ultra small unmanned ship having a length of about 1 to 2M. .

The self-contained vertical line 2 is formed by spacing the propeller 57 at a predetermined distance from the bottom as in the plotter vertical line 3 described above, thereby replacing the plotter vertical line 3 described above to increase the water retention time of the powder liquid .

By providing the self-contained vertical line 2 made up of a very small ship, it is possible to more easily control the vertical line with the blending means and to increase the algae removing effect. The self-contained vertical line 2 has a function of replacing the above-mentioned vertical line by increasing the length of the water retention time of the powder liquid by forming the propeller 57 at a predetermined distance from the bottom surface as in the plotter vertical line 3. The configuration and function of the self-contained vertical line (2) are substantially the same as those of the plotter vertical line (3), and thus are omitted for convenience of explanation.

The plotter vertical line (3) and the self-standing vertical line (2) can be adjusted by connecting the power line and the adjustment line (not shown) to the main line or the land line and attaching the plotter to the line .

In addition, the powder liquid jetting system according to the present invention can make the jetting operation possible by mounting the jetting device 50 on the plotter vertical line 3 and the self-propelled vertical line 2. 5, the powder liquid injection system according to the present invention includes a high-pressure pump 10, a hopper 30 and an ejector 20 (see FIG. 1) mounted on a main line 1, The injector 50 can be mounted on the plotter vertical line 3 or the vertical line 2. [ 5, only the fourth embodiment having the injector 50 in the vertical line is shown. However, this is for convenience of explanation, and the space excluding the plotter coupling portion of the plotter vertical line 3 shown in FIG. 3, that is, The injection device 50 shown in Fig. 5 can be mounted on the release space 3B formed by releasing one or a part of the plotter 3 of the plotter vertical line 3 in a state in which the floating force can be ensured.

When the above-described high-pressure pump 10, the hopper 30, the ejector 20, etc. are mounted on a ship, a minimum space is required, so that the size of the main line is inevitably limited. Therefore, in order to effectively remove the algae on the coast or the like where the water depth is shallow or inaccessible to the main line, the powder liquid is dispersed through the jetting device 50 mounted on the plotter vertical line 3 and the vertical line 2, It is also possible to remove algae from difficult areas.

Instead of aerial spraying of powdered liquid at this time, the injector 20 is connected directly to the feeder tube 55 from the ejector 20 to the plotter longitudinal line 3 or the self-contained vertical line 2, and the injector 50 is connected to the plotter longitudinal line 3 or And it is preferably formed on the bottom surface of the vertical line 2 so as to be directly jetted from the front portion of the propeller 57.

The powder liquid injection system according to the present invention is characterized in that the injector 50 mounted on the plotter longitudinal line 3 or the self-propelled vertical line 2 is a submerged venturi tube 50A. An upper sectional view of Fig. 6 shows the venturi pipe 50A.

The aeration type venturi pipe 50A injects a mixture of the powder and the liquid into the water, wherein the powder liquid and the air are mixed with each other to further enhance the algae removing effect. For the mixing of powdered liquid and air, the aeration-type venturi tube 50A has a powdered liquid inlet connected to the injector 50 through an inlet tube 58, as shown in Figures 5 and 6, And a venturi portion 59 for generating an air suction negative pressure.

The air suction hole 52 is protruded from the outer surface of the aeration type venturi tube 50A and penetrates the inside of the aeration type venturi tube 50A. The air suction hole 52 can be naturally introduced by the suction force of the venturi portion 59 and forced air can be introduced from the air compressor. The air suction hole 52 is formed with an air tube for receiving air naturally or from an air compressor (not shown).

The suction hole 52 is oriented in a direction eccentric to one side without being directed toward the center of the venturi portion 59. This is to allow the air introduced into the suction hole to naturally rotate in the venturi portion 59 so as to be mixed with the powder liquid more easily. At this time, it is preferable that the eccentric direction of the suction hole (52) is eccentric to the right so that the swirling motion of the introduced air becomes more active due to the influence of the turning force according to the rotation of the earth.

Furthermore, in order to further facilitate the mixing of the air and the powder liquid, the aeration type venturi tube 50A may embed an amplifying member. The amplifying member is composed of a helical spiral (not shown) at an inlet through which the powder liquid is introduced, thereby forming a vortex (swirl) upon the inflow of the powder liquid. It is preferable that the spiral portion is formed in the right direction so as to increase the rotational force of the powdered liquid that is influenced by the influence of the turning force.

When the powdery liquid introduced into the aeration type venturi pipe 50A causes a vortex, the outside air can be sucked more strongly through the air suction hole 52, and the air introduced into the venturi portion 59 is separated into powdery liquid And the mixed air is swirled in the powder liquid by the vortex so that the contact area (contact frequency) with the powder liquid is increased so that the mixing can be performed more easily and the efficiency of the algae removal after the powder liquid discharge can be improved .

Thus, the air introduced from the air suction hole 52 is atomized and uniformly mixed with the powder liquid passing through the aeration type venturi tube 50A, whereby a larger amount of atomized air is mixed into the powder liquid, It is possible to increase the dissolved oxygen amount of the powder liquid to further enhance the algae elimination effect together with the loess contained in the powder liquid.

As described above, by providing the aeration type venturi pipe 50A on the front surface of the propeller 57 of the self-propelled vertical line 2 or the flow-line type line 3, the powder liquid to be sprayed backward is propelled by the propeller 57 So that the effect of removing algae can be further improved. The powdery liquid which forms the vortex due to the spiral amplifying member is amplified by the rotation of the propeller 57 and can be extended to the rear of the vertical line.

By using the micro plotter vertical line 3 or the self-propelled vertical line 2, it is possible to improve the accessibility to the coast or the area where the large main line 1 is inaccessible and the rotation of the venturi pipe 50A and the propeller 57 This makes it easier to remove algae through the widely dispersed powdered liquid, and a high removal effect can be expected.

5 and 6, the powder liquid injection system according to the present invention is mounted separately on the above-described aeration type venturi pipe 50A and the above-described floatation line 3 or the vertical line 2 Means 54 may be further included. The mounting means 54 is formed on the bottom surface of the plotter longitudinal line 3 or the vertical line 2 and is engaged with the aeration type venturi pipe 50A.

The mounting means 54 includes a main body 500 connected to the bottom surface of the plotter longitudinal line 3 or the vertical line 2 and an upper panel 555 connected to one side of the main body and engaged with the venturi pipe 50A. And a lower panel 530. A side view of the vertical line 2 shown in Fig. 5, a bottom view seen from the lower side of the vertical line 2 and an engagement relationship between the vertical line 2 and the mounting means 54 and the aeration type venturi pipe 50A More accurately.

5 shows that the anchor type venturi tube 50A is mounted with the mounting means 54 on the vertical line 2 but it is also possible to use the float vertical line 3 in addition to the vertical line 2, It goes without saying that it can be applied to all equipments. In FIG. 5, two aeration type venturi pipes 50A are shown mounted on both sides through the mounting means 54, but there is no limitation on the number of the aeration type venturi pipes 50A.

The mounting means allows the detachable venturi tube 50A to be easily detachable, and the mounting operation can be performed quickly and accurately without risk of dropping or loss of the bolt even in the presence of vibration when the venturi tube 50A is mounted .

The mounting means 54 will now be described in more detail with reference to FIGS. 5 and 6. FIG.

The mounting means includes a main body 500, a lower panel 530 coupled to the main body 500 in a detentable manner, and an upper panel 555 coupled to the upper portion of the main body 500 so as to be raised and lowered The lower panel 530 and the upper panel 555 enclose and fix the aeration type venturi pipe 50A. The mounting means 54 includes a tongue spring 590 which is built in the main body 500 and elastically supports the upper panel 555 and the lower panel 530 and the upper panel 555, Type venturi pipe 50A, as shown in Fig.

The lower panel 530 is protruded to the outside of the main body 500 and exposed to the outside of the main body 500. The lower panel 530 has a lower concave semicircular part 531 for contacting and covering the outer surface of the main body 500 of the aeration type venturi pipe 50A And a slit-shaped restraining portion 533 and a nut portion 535 having a through-hole shape are formed on the inner side of the main body 500.

[ It is possible to prevent the tongue spring 590 from coming off and to prevent the bracket part 553 of the upper panel 555 from coming off so as to secure the connection between the aeration type venturi tube and the vertical or vertical line of the plotter, When the venturi tube is replaced, the fixing bolt and the like are not detached, so that the user can easily perform the replacement work.

In the powder liquid injection system according to the present invention, a sweet joint can be attached to the connection portion so that the connection hose and the vertical line 2 can move relative to each other smoothly, thereby improving the adjustment and mobility of the vertical line 2. Furthermore, it is also possible that the vertical line 2 further includes a radio control unit and is guided by a radio control method other than the wire control method described above.

Herein, in describing the powder liquid system, the object to be mixed to be supplied to the ejector 20 through the hopper 30 has been described based on the loess powder, but this is not limitative. Thus, in the present specification, the powder includes all the mixed objects which are effective for algae removal not only in the yellow loess but also in the lake such as activated carbon.

Also, in the present specification, the object of blending and the like is accomplished by mixing and spraying the mixed object with a liquid by referring to the mixed object, but this is also for the convenience of explanation, and thus it is not limited to the powder form.

The powder material of the loess or the like may be mixed with the ejector 20 through the hopper 30 by a selection of a person skilled in the art or, in some cases, a mixing object in the form of a gel (gel material, semi-solid material such as mayonnaise, And injected by using the injection device 50 after mixing with the liquid. Therefore, it is more preferable that the useful microorganisms and the like having a great effect on algae removal are formed into a gel state and mixed with a liquid and then sprayed.

Furthermore, it is also possible to mix the useful microbes in the gel state with the powdered yellow loess or the like, or to cultivate useful microorganisms in loess or the like, and then to supply the gelate to the ejector 20 through the hopper 30 to be.

In this case, when the mixing object in the gel state is used, the suction control device 40 or the hopper 30 may be provided with a screw-type injection device or the like which is not a valve type in order to smoothly supply the mixture object to the ejector, can do.

It is possible to inject various kinds of materials of the kind that do not smoothly supply by the self weight or the venturi effect of the ejector by using the injection device of the present invention as well as the mixture object mixed with the gel or gel, It is clear that the above-described screw-type injection device can further include a conventional supply means capable of being selected by a person skilled in the art according to the injection material (that is, the mixture object) and capable of forced injection or supply.

While the preferred embodiments of the present invention have been described with reference to the accompanying drawings, it is to be understood that the scope of the present invention is defined by the appended claims rather than by the foregoing description and drawings.
