Description

Technology Field

[0001] The present invention relates to a separation device for separating green algae and water.

[0002] Specifically, the invention relates to a separation device for separating algae and water, wherein water containing algae (hereinafter referred to as 'algae water') is introduced and the water falls through the mesh pores by gravity to separate it from the algae.

[0003] Furthermore, the invention relates to a separation device for separating algae and water, which provides vibration to enable water to be separated from algae more easily, prevents the adsorption of algae inside the device through vibration, and facilitates the removal of adsorbed algae. Background Technology

[0005] The 'Nok' in 'Nok-algae' (green algae) means green, and 'Joryu' refers to lower plants that live in water and lead an autotrophic life using photosynthetic pigments. In other words, green algae refer to algae that appear green because their chlorophyll bodies contain a large amount of chlorophyll. Examples of green algae include *Cornus controversa*, *Parasitic sea lettuce*, and *Sargassum horneri*.

[0006] This type of algal bloom refers to a phenomenon where the water turns green due to an increase in green algae caused by rising nutrients in aquatic ecosystems such as rivers, seas, and lakes. Green algae proliferate significantly even in streams with slow currents. In some areas, a red tide occurs, where plankton proliferate and the water turns yellowish-brown.

[0008] Although algal blooms have occurred consistently every year, they can become particularly severe at certain temperatures due to the influence of heatwaves. Both red tides and algal blooms are closely linked to rising temperatures. When temperatures rise and water temperatures remain above 25 degrees Celsius while sunlight increases, an excessive supply of nutrients into the water causes green algae and plankton to proliferate actively.

[0009] When algal blooms become severe, they cause problems for the aquatic ecosystem. This is because when algae cover the water surface, they block sunlight from penetrating the water; consequently, the influx of additional oxygen is cut off, leading to a decrease in dissolved oxygen levels. A drop in dissolved oxygen results in the death of aquatic life. Dissolved oxygen refers to the amount of oxygen dissolved in water, such as rivers and lakes, and is one of the indicators of water quality pollution.

[0011] Algal blooms frequently occur even in areas with slow water flow. When high temperatures caused by heatwaves persist, water dries up and slows the flow, and if rainfall decreases, the water volume also diminishes, exacerbating the damage.

[0012] While algal blooms are generally not known to pose a significant risk to the human body, there is a possibility that they could cause direct harm. Drinking lake water contaminated with toxic cyanobacteria can lead to liver damage, vomiting, and abdominal pain. Furthermore, long-term consumption over several decades can result in death.

[0013] Furthermore, when an algal bloom occurs, fish and aquatic life die, emitting foul odors and destroying the aquatic ecosystem of the area. Some algae that destroy aquatic ecosystems produce toxic substances; representative examples include Anabaena, Microcystis, and Geosmin, which are types of cyanobacteria frequently found in Korea. While Geosmin is harmless to humans, it is the cause of foul odors in water.

[0014] In fact, the toxins produced by these cyanobacteria are also the most serious problem. In 1878, animals died for the first time in Australia due to an algal bloom. Since then, damage to livestock and wildlife caused by geosmin toxins has occurred in various parts of the world. Although there have been no reports in Korea yet, the possibility of damage occurring cannot be ruled out.

[0016] Water wheels are also used to resolve such algal blooms.

[0017] In this regard, Registered Patent Publication No. 10-0699598 describes a device for removing green algae and red tide.

[0018] The above technology comprises: a flat portion having several holes and a rim portion of a certain height formed obliquely upward along the edge of the flat portion, and a dish-shaped panel body made of a material with a specific gravity less than that of water; a pipe located on the bottom surface of the flat portion and coupled to each hole; and a water discharge means for forcibly discharging water contained in the dish-shaped panel body to the outside of the dish-shaped panel body.

[0020] This technology utilizing water wheels operates on the principle that as the wheels rotate, they agitate the lake water, and by introducing air to the bottom of the lake as the water mixes, the dissolved oxygen content is increased. In addition, there is a method of operating algae removal vessels equipped with devices that suck in, filter, and recover algae. While this method has the advantage of being environmentally friendly, maintenance costs are high.

[0022] The simplest and safest method is to let the water flow. In fact, when the sluice gates of the Chungju Dam, Ipo Weir, and Yeoju Weir were opened, the algal bloom in the Han River decreased noticeably, and rainfall also contributed significantly to the reduction of the algae. This can be seen as similar to the method of using water wheels. By letting the water flow out, it is mixed, thereby eliminating the oxygen-free layer within the water. Prior art literature

[0052] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.

[0054] Before proceeding with the following description with reference to the drawings, it should be noted that matters not necessary to reveal the gist of the invention, namely known configurations that a person skilled in the art with ordinary knowledge can obviously add, have not been illustrated or specifically described.

[0056] The present invention relates to a separation device for separating green algae and water.

[0057] Specifically, the invention relates to a separation device for separating algae and water, wherein water containing algae (hereinafter referred to as 'algae water') is introduced and the water falls through the mesh pores by gravity to separate it from the algae.

[0058] Furthermore, the invention relates to a separation device for separating algae and water, which provides vibration to enable water to be separated from algae more easily, prevents the adsorption of algae inside the device through vibration, and facilitates the removal of adsorbed algae.

[0060] The separation device for separating green algae and water according to the present invention will be explained through the attached drawings.

[0061] FIG. 1 schematically shows a separation device for separating green algae and water according to the present invention, and FIG. 2 and FIG. 3 show a separation device for separating green algae and water according to the present invention from the top.

[0063] The present invention according to the attached drawing includes a box-shaped receiving container (10) and a mesh portion (20) coupled inside the receiving container (10).

[0064] A separate hose (1) is installed on one side of the upper portion of the above-mentioned receiving container (10). The installation of the hose (1) means placing the hose (1) over the upper surface. This hose (1) serves to introduce algae water into the receiving container (10).

[0066] On one side of the bottom surface (11) of the above-mentioned receiving container (10), a discharge hole (111) is formed to penetrate in the upward / downward direction.

[0067] In addition, the mesh portion (20) coupled to the above-mentioned receiving container (10) is composed of a screen or the like configured to form a plurality of perforations, such as a mesh net, and these perforations are configured to have a size such that water can pass through but algae cannot.

[0068] The above mesh portion (20) also has a second discharge hole (not shown in the drawing) formed therein, having a size and position corresponding to the discharge hole (111) of the above receiving container (10).

[0069] In connecting such a net (20) to a receiving box (10), a separate connecting clip (21) may be used. The connecting clip (21) may be a large clip for organizing documents. As shown in FIGS. 2 and FIGS. 3 of the attached drawings, this connecting clip (21) connects the receiving box (10) and the net (20) to firmly secure the net (20).

[0070] Additionally, the discharge hole (111) and the second discharge hole are configured to be closed using a separate cover. The cover has a size and shape corresponding to the discharge hole and the second discharge hole, and is opened from the discharge hole when removing the algae after separating the algae and water.

[0072] Meanwhile, the bottom surface (11) of the above-mentioned receiving container (10) is configured to have a mesh shape having a plurality of through holes. The mesh size of such receiving container (10) may be larger than that of the mesh portion (20).

[0073] That is, the green algae water supplied to the inside of the net (20) can be discharged through the net (20) and the water contained in the green algae water can be discharged through the bottom surface (11) of the receiving container (10).

[0075] As another example, as shown in FIG. 4 of the attached drawings, a separate plate (12) may be further configured on the bottom surface (11) of the receiving container (10), and the plate (12) has a size corresponding to the bottom surface (11) of the receiving container (10). This plate (12) may also form a third discharge hole (121) corresponding to the discharge hole (111).

[0076] FIG. 4 schematically shows a separation device for separating green algae and water according to another example of the present invention.

[0077] At this time, the above-mentioned plate (12) can be configured to have a mesh shape identical to the bottom surface (11), and a plurality of springs are attached to the lower surface of the plate (12) to be spaced apart from the bottom surface (11) of the receiving container (10) at a certain distance and to have elasticity.

[0078] In this case, water discharged through the cover plate (12) can be guided to be discharged through the discharge hole (111), and as another example, unlike FIG. 4, both the cover plate (12) and the bottom surface (11) can be configured to have the shape of a mesh net.

[0080] Meanwhile, as shown in FIGS. 2 and FIGS. 3 of the attached drawings, a control unit (30) that controls length adjustment is further included on one side of the receiving unit (10). At this time, the control unit (30) is composed of a cylinder, and the end of the rod of the cylinder can be positioned inside the receiving unit (10) by penetrating the receiving unit (10).

[0081] To this end, a hole may be formed on one side of the above-mentioned mesh (20) for the rod of the cylinder to pass through.

[0082] At this time, the control unit (30) is composed of one or more units, and an adsorption prevention unit (40) is coupled to the end thereof.

[0084] This adsorption prevention part (40) can be moved forward or backward by adjusting the length of the control part (30) as shown in Figures 2 and 3 of the attached drawings. For example, when green algae are adsorbed on the bottom surface (11) of the receiving container (10) as shown in Figure 2, the adsorption prevention part (40) can push the green algae on the bottom surface (11) and be discharged in the direction of the discharge hole (111) as shown in Figure 3.

[0085] In this case, a person can assist with the discharge by using a separate pusher.

[0087] The above-mentioned adsorption prevention part (40) can be configured as shown in FIGS. 5 and FIGS. 6 of the attached drawings.

[0088] FIG. 5 shows the configuration of an adsorption prevention part of a separation device for separating green algae and water according to the present invention, and FIG. 6 shows the configuration of an adsorption prevention part of a separation device for separating green algae and water according to another example of the present invention.

[0090] The adsorption prevention part (40) according to Fig. 5 of the attached drawing includes a pushing end (41) that contacts the bottom surface (11) of the receiving container (10) to perform pushing; and one or more connecting parts (42) formed protruding upward from the pushing end (41).

[0091] At this time, the number of the coupling portions (42) corresponds to the number of control portions (10), and the end of the control portion (30), i.e., the rod of the cylinder, is coupled to the coupling portions (42). At this time, various coupling methods used in the field of conventional cylinder technology can be employed for coupling the rod.

[0092] In addition, the reason the above-mentioned connecting part (42) is positioned above the pushing end (41) is to ensure that the pushing end (41) is configured at the lowest possible position.

[0094] The above-mentioned push end (41) includes an inclined surface (411) formed so that the front direction is inclined downward, so that the end is formed sharply, and a groove (412) formed in the width direction of the push end (41) is further formed on one side of the rear lower surface.

[0095] One or more vibration generators (motors, etc.) are connected to the above-mentioned groove (412). The connection can be achieved using separate bolts and brackets, and the vibration generators are configured to apply vibration downwards to the pushing end (41).

[0096] Accordingly, when the above-mentioned adsorption prevention unit (40) is not operating, the vibration generator applies vibration to the bottom surface (11) or the cover plate (12) to facilitate the separation of water from the algae.

[0097] In addition, when the above-mentioned adsorption prevention unit (40) moves forward to operate, the application of vibration can facilitate the detachment of the adsorbed algae.

[0099] Meanwhile, as shown in Fig. 6 of the attached drawings, a box (413) can be joined to one side of both ends of the above-mentioned end portion (41) by bolting, welding, etc.

[0100] A side wall detachment section (50) may be formed inside such a box (413), and the side wall detachment section (50) is used to remove algae adsorbed on the side walls of the receiving container (10) or the mesh section (20). When not in use, it is folded and stored inside the box (413), and when in use, it is unfolded as shown in FIG. 6. To elaborate, the side wall detachment section (50) is configured such that a plurality of unit modules (51) having a block shape are joined together by hinges so that it can be folded and unfolded.

[0101] At this time, a blade (52) may be integrally formed on one side of the unit module (51) by welding or the like, and the blade (52) is formed so that it can be positioned in a straight line on the same line when the unit module (51) is unfolded in a straight line.

[0102] In addition, a hanging part (53) is formed on the uppermost side of the unit module (51) by welding, etc.

[0103] These hanging portions (53) are configured to include a groove like a handle so as to be hung on a guide (14) formed on the side wall of the receiving container (10) shown in FIG. 4.

[0104] The above guide (14) is configured to be inserted into a guide groove (13) formed concavely along the longitudinal direction on the side wall of the receiving container (10). At this time, to prevent the guide (14) from coming off, the end may be expanded into a 'convex' shape, and the guide groove (13) may also have the same shape.

[0105] Accordingly, when the control unit (30) is driven with the side wall detachment unit (50) unfolded and the hook unit (53) hooked on the guide (14), the guide (14) moves along the guide groove (13), and the blade (52) of the side wall detachment unit (50) pushes while sweeping the surface of the mesh unit (20) to remove the adsorbed algae.

[0106] At this time, the mesh portion (20) can form a hole along the guide groove (13) so that the guide (14) protrudes into the mesh portion (20).

[0108] According to the separation device for separating algae and water according to the present invention, configured as described above, water containing algae (hereinafter referred to as 'algae water') is introduced so that the water falls through the mesh pores by gravity and can be separated from the algae.

[0109] In addition, it provides vibration to allow water to be separated from the algae more easily, prevents the adsorption of algae inside the device through vibration, and facilitates the removal of adsorbed algae.

[0111] The description above using the drawings describes only the main aspects of the present invention, and it is obvious that the present invention is not limited to the configuration of the drawings, as various designs are possible within the technical scope. Explanation of the symbols
