Description

Water purification device utilizing the aeration function of a water wheel

[0001] The present invention relates to a device capable of efficiently improving and purifying the water quality of rivers or lakes by utilizing the aeration function of a water wheel.

[0002] Generally, algal blooms are a phenomenon in which algae proliferate in large numbers and change the color of the water to green. When an algal bloom occurs, the amount of dissolved oxygen in the water decreases, fish die in large numbers, and the water emits a rotting smell, causing immense damage to daily life and fisheries.

[0003] Although algal blooms can be temporarily removed by injecting substances such as loess or chemicals, this method has many side effects. Furthermore, as the phenomenon has recently worsened due to abnormal weather conditions and has become a social issue, problems such as contamination of drinking water sources, fish kills, and foul odors are continuously occurring.

[0004] Looking at the invention of the prior art document 1 related to this background technology, this invention is a device having a loess spraying function that allows loess powder to be finely dispersed by the downward means by spraying loess liquid through a nozzle close to the downward means to enhance the effect of removing green algae and red algae. However, as pointed out above, this invention has the disadvantage that although it can remove green algae and red algae by spraying loess liquid, the loess liquid may cause other environmental problems.

[0007] In order to solve the problems of the current technology described above, the present invention aims to prevent water pollution caused by algal blooms by installing a structure including a water wheel in a river or lake where algal blooms have occurred, or by installing a water wheel on a barge, and by using a means to continuously supply a large amount of oxygen from the air into the water during the rotation process of the water wheel, thereby enabling aquatic organisms in the area where algal blooms have occurred to breathe smoothly.

[0008] Furthermore, the present invention aims to prevent water pollution caused by algae blooms by means of continuously introducing a large amount of oxygen from the air into the water during the rotation process of the water wheel, and by utilizing relatively clean, unpolluted water from outside a river or lake as a drop water to purify the water quality in areas where algae blooms have occurred and to enable aquatic organisms to breathe smoothly.

[0009] In addition, the present invention aims to provide a device that minimizes side effects by not using a method of treating and removing green algae or red algae using drugs or red clay.

[0047] In describing the present invention, if it is determined that a detailed description of related current prior art (known technology) could obscure the essence of the present invention, such detailed description is omitted.

[0048] One of the embodiments of the present invention is described below.

[0049] The present invention relates to a device capable of efficiently improving and purifying the water quality of rivers or lakes by utilizing the aeration function of a water wheel.

[0050] The present invention is characterized by the ability to effectively purify the water of a river or lake by using the water of a river or lake or relatively clean external water to rotate a water wheel (100) using drop energy, and simultaneously using an aeration function through an air bucket (112) installed on the water wheel.

[0051] As explained earlier, when an algal bloom occurs, the amount of dissolved oxygen in the water decreases rapidly, making it impossible for various aquatic organisms, such as fish, to survive. As they die and rot, various foul odors are produced.

[0052] To prevent this phenomenon, the problem can be resolved to some extent by using devices such as mechanical air blowers to continuously supply oxygenated air to fish tanks or aquariums; however, using this method in rivers or large lakes is not very economical compared to its effectiveness.

[0053] In this regard, a method is sometimes used to continuously create water droplets using a device with rotating blades to supply air containing oxygen into the water, but this method has the disadvantage of low energy efficiency because it requires operating a motor to rotate the device.

[0054] Furthermore, when looking at the process of operating a conventional water wheel similar to the aforementioned device with rotating blades, the problem is that the structure of the water wheel makes it difficult to introduce oxygen-containing air into the water, and the amount of air is also too small.

[0055] The present invention is characterized in that, in order to solve the problems of the current water wheel structure as described above, a water wheel (100) with a structure that rotates using the falling of water is formed with a water receiving part (111) on the outer circumference of the water wheel rim (101) and a plurality of air bucket parts (112) formed below the water receiving part or at a certain distance, so that oxygen from the air can be continuously supplied to the water for a long time by the air bucket parts.

[0056] The features of the present invention are clearly shown by looking at the water aberrations in FIGS. 1 to 7, which are one of the embodiments according to the present invention.

[0057] First, Figure 1 conceptually shows an example of a water aerator (100) according to the present invention.

[0058] Looking at FIG. 2, the water aberration of type (a) in FIG. 1 rotates around the rotation axis (113). Although the drawings of the present invention show the water aberration rotating in a clockwise direction on the drawings, it is not necessary to rotate in this direction, and there is no difference in the operation and effect according to the present invention even if it rotates in a counter-clockwise direction.

[0059] However, if the water wheel according to the present invention rotates in the counterclockwise direction, the roles of the water receiving part (111) and the air bucket part (112) are reversed and function.

[0060] Therefore, it should be noted that, unless there are special circumstances, the present invention is described based on the appearance of rotation in the clockwise direction.

[0061] In addition, in the description of the present invention, the number of water receiving parts and air bucket parts formed on the rim of the water wheel is depicted as eight, but since this number is arbitrarily limited for the purpose of describing the present invention, it should be understood that the description of the present invention is not necessarily limited to eight.

[0062] Therefore, considering the symmetrical arrangement structure, it is generally preferable to have four or more water receiving and air bucket sections formed on the outer perimeter of the water wheel, and since it does not necessarily have to be a multiple of four, the implementer can appropriately design the number to be, for example, 4 to 20 depending on the size of the water wheel.

[0063] In addition, a water receiving portion (111) and an air bucket portion (112) may be formed on the outer surface of the water wheel rim (101) and below or at a certain distance from the water receiving portion. These portions may be formed with a symmetrical shape and form, or asymmetrically.

[0064] Furthermore, an air bucket section (112) may be formed at a certain distance from the water receiving section on the outer edge of the water wheel, but since resistance from water may occur as the water wheel rotates if formed in this way, it is preferable to keep the distance as short as possible or to form the air bucket section attached to the water receiving section.

[0065] In the structure of the water wheel as in the present invention, the water wheel rotates by means of falling water (300) through the external water pipe (301), etc.

[0066] Although the actual appearance of water falling through external water pipes, etc. may differ from that depicted in FIGS. 2 to 4, etc., the description of the invention should be understood with the understanding that the drawings related to the description of the invention are conceptually simplified to explain the operation and effects of the invention.

[0067] Therefore, the actual rotational conditions and environment of the water wheel according to the present invention may differ from those depicted in the drawings.

[0068] As can be seen in FIG. 3, the water wheel of the present invention is rotated by gravity as the falling water (300) falls into the water receiving part (111) and the water receiving part becomes heavier.

[0069] In the present invention, the water receiving part is characterized by having the shape of a distorted cuboid with an open upper surface, and its shape is similar to the shape of a bucket of an excavator. Since the shape and form of such a water receiving part are known technologies in the field of water wheels, a detailed description or illustration is omitted here.

[0070] During the rotation process described above, as can be seen in Figure 2, the air bucket section (112) does not have a structure to receive or receive falling water, so the space inside the air bucket section is filled with air and rotates together with the water wheel as it rotates.

[0071] As shown in FIG. 4, during the rotation process of this water wheel, the end of the air bucket wall (122), which is the end of the air bucket wall (123), comes into contact with the water surface (200) and rotates, entering the water.

[0072] In this way, when the air bucket (112) enters the water, the oxygen (131) in the air inside the space of the air bucket is trapped in the sealed space (124) before the air bucket reaches the water surface.

[0073] For example, this phenomenon is based on a principle similar to the air pocket that forms when a ship capsizes at sea.

[0074] As shown in FIGS. 6 and 7, the oxygen (131) in the air trapped in the sealed space (124) as described above remains trapped during the rotation of the water wheel, and this process is maintained until the air bucket section (112) comes out of the water again due to the rotation of the water wheel about 180 degrees after the air bucket section wall end (123), which is the end of the air bucket section wall (122), touches the water surface (200).

[0075] Figure 5(b) shows the process of oxygen (131) in the air trapped in the sealed space (124) described above dissolving into the water.

[0076] The process of oxygen (131) in the air trapped in the sealed space (124) described above dissolving into the water continues as the water wheel rotates, as can be seen in FIG. 6, and FIG. 7 clearly illustrates this.

[0077] As described above, the water wheel according to the present invention includes a water receiving section (111) as in the current conventional technology, and further includes an air bucket section (112). When the water wheel rotates and enters the water through this air bucket section, a sealed space (124) is formed instantaneously. Since oxygen in the air trapped in this sealed space dissolves in the water and changes into dissolved oxygen, aquatic organisms can breathe in the water, thereby preventing water pollution caused by algae blooms, etc.

[0078] Another embodiment of the present invention is described below.

[0079] In the present invention, the configuration of the air bucket part is important because the air bucket part causes oxygen in the air to dissolve into the water.

[0080] In the drawings of the present invention, the water receiving section and the air bucket section are depicted as being formed symmetrically in the same shape, but the invention is not necessarily limited to this form.

[0081] However, if the water receiving section and the air bucket section are formed symmetrically in the same shape as above, there is an advantage in that when the direction of rotation of the water wheel changes, the water receiving section and the air bucket section can switch roles and function accordingly.

[0082] In the air bucket section (112) according to the present invention, the size or shape of the wall surface (122) of the air bucket section is important.

[0083] In the present invention, the shape or form of the air bucket section is similar to the shape of the water receiving section, having a form similar to the bucket of an excavator.

[0084] As can be seen in FIG. 8 (a), if only the wall surface (121) of the water receiving section (111) is formed as in the current conventional technology, the phenomenon of oxygen in the air dissolving into the water, which is a feature of the present invention, does not occur, and as shown in FIG. 8 (b), the wall surface (122) of the air bucket section (112) must be formed so that a sealed space (124) can be formed during the rotation process of the water wheel.

[0085] Looking at FIG. 9(a), the wall (122) of the air bucket section is formed perpendicular to the water surface (200), and looking at FIG. 9(b), the wall (122) of the air bucket section is formed at an angle (A1) less than 90 degrees to the water surface (200).

[0086] On the other hand, looking at (c) of FIG. 9, the wall (122) of the air bucket section is formed at an angle (A2) greater than 90 degrees with respect to the water surface (200).

[0087] In the present invention, the shape of the air bucket section wall (122) is such that, among the shapes described above, the shape of (c) in FIG. 9 has the longest distance (L) between the water wheel edge end (102) and the point where the air bucket section wall end (123) touches the water surface (200), and as a result, the largest water surface contact area is obtained in the sealed space (124), so the amount of oxygen in the air dissolved in the water increases.

[0088] Therefore, assuming that the water receiving section and the air bucket section are not formed symmetrically in the same shape, but are rotated only in one direction of clockwise rotation as shown in the drawings, it can be seen that it is preferable for the air bucket section wall (122) to be formed at an angle greater than 90 degrees with respect to the water surface (200).

[0089] However, if the angle of the air bucket wall surface relative to the water surface is formed at too large an angle, the radius of rotation of the rotating water wheel increases, and furthermore, the three-dimensional size of the air bucket section itself increases. Therefore, in the present invention, it is preferable that the angle (A) formed between the virtual vertical line (201) of the water surface and the air bucket wall surface (122) be formed in the range of 20 to 50 degrees.

[0090] If the angle (A) formed by the virtual vertical line (201) of the water surface and the wall (122) of the air bucket section is less than 20 degrees, the distance (L) between the end of the water wheel rim (102) and the end of the wall (123) of the air bucket section touches the water surface (200) becomes shorter, and the amount of oxygen in the air dissolved in the water decreases. If it is 50 degrees or more, the distance (L) between the end of the water wheel rim and the end of the wall of the air bucket section touches the water surface becomes longer, and the amount of oxygen in the air dissolved in the water increases, but the overall size of the water wheel becomes too large, the radius of rotation of the water wheel also increases, and furthermore, the resistance applied to the water wheel that moves by water power increases, so there may be a disadvantage that the rotation of the water wheel becomes impossible.

[0091] In the present invention, the angle (A) formed by the virtual vertical line (201) and the wall surface (122) of the air bucket can preferably be set in the range of 20 to 25 degrees, but is not necessarily limited to this form.

[0092] In addition, if the total volume of the air bucket section (112) in the present invention is designed to be 40 to 60% of the total volume of the water receiving section (111), the size of the air bucket section becomes relatively smaller compared to the water receiving section. Since configuring the air bucket section in this way reduces the resistance that occurs while the water wheel rotates, thereby enabling smooth rotation, the implementer of the present invention can design and implement the size of the air bucket section in various ways.

[0093] As can be seen in FIG. 11, a method to reduce the volume of the air bucket section may be used to reduce the horizontal length (L) of the air bucket section (112), and furthermore, a method to reduce the length of the wall (122) of the air bucket section may be used. Therefore, the implementer may reduce the total volume of the air bucket section (112) by reducing the horizontal length (L) of the air bucket section or the length of the wall (122) of the air bucket section, or by reducing both the horizontal length (L) of the air bucket section and the length of the wall (122) of the air bucket section, or by other methods.

[0094] In this invention, the materials of the water wheel, the water receiving section, and the air bucket section may be traditional wood; however, since wood may have durability issues, it is preferable to manufacture them using metal materials.

[0095] For example, the implementer may use iron material, stainless steel material, or aluminum alloy material for manufacturing.

[0096] Furthermore, since there is no impediment to the operation and effects of the present invention even if the water wheel of the present invention is constructed using a polymer resin plastic material rather than necessarily using a metal material, the practitioner of the present invention can complete the construction of the water wheel, water receiving part, and air bucket part of the present invention by using a suitable material.

[0097] Another embodiment of the present invention is described below.

[0098] In the present invention, the water wheel described above can be installed in a fixed manner, but there are many difficulties in moving, installing, and operating the water wheel when the places where water purification is required are scattered in many locations.

[0099] Accordingly, to implement the present invention, as can be seen in FIGS. 12 to 14, a water wheel (100) is fixedly installed on a barge (400) floating on a river or lake, and a water tank (302) structure is formed at a high place on the barge, and then water (300) is dropped onto the water wheel through a water pipe (301) connected to the water tank to make the water wheel rotate.

[0100] The size of the barge can be appropriately designed according to the size of the water wheel or the size of the river or lake to be purified, and furthermore, the size of the water tank (302) or the size of the water pipe (301) can also be appropriately designed according to the size of the water wheel or the size of the river or lake to be purified, so they are not specifically illustrated or explained here.

[0101] The water in the water tank (302) can be stored by using a water pump to draw up water from a river or lake and then flowing it through a water pipe (301) and then dropping water (300) onto a water wheel (100). In the present invention, the water drop height (H), which is the distance from the end of the water pipe to the water receiving part of the water wheel, can be set in the range of 5 to 10m, and if smooth rotation of the water wheel is possible, it is possible to set the water drop height (H) to 5m or less or 10m or more.

[0102] Even if the water wheel of the present invention is installed in a fixed manner, it can similarly be allowed to flow through the water pipe (301) and then drop water (300) onto the water wheel (100). The water drop height (H), which is the distance from the end of the water pipe to the water receiving part of the water wheel, can be set in the range of 5 to 10 m, and if smooth rotation of the water wheel is possible, it is possible to set the water drop height (H) to 5 m or less or 10 m or more.

[0103] Another embodiment of the present invention is described below.

[0104] In the present invention, as described above, the water wheel may be installed in a fixed manner, or it may be installed on a barge by utilizing a barge.

[0105] However, whether the waterwheel is installed as a fixed unit or a barge is used, a problem may arise as to where the water for the water tank used to rotate the waterwheel of the present invention is drawn from and utilized.

[0106] Typically, when implementing the present invention, since it is a facility for purifying the water quality of a river or lake, water is drawn up from a river or lake through the inlet pipe of a water pump and stored in a water tank, and the water in this tank is dropped onto a water wheel to rotate the water wheel.

[0107] However, there are limitations to purifying the water of a river or lake by allowing oxygen (131) from the air to dissolve into the water through the sealed space (124) of the air bucket (112), which is the effect of the present invention, so it may take a long time or the power consumption due to the operation of the water pump may be excessive.

[0108] Therefore, another feature of the present invention is that, in the implementation of the invention, the water flowing into the water tank is not water from a river or lake to be treated, but rather water from an external, relatively clean, unpolluted river or stream, or water from a lake or reservoir, and is utilized as fallwater.

[0109] As described above, if water from relatively clean, unpolluted rivers, streams, lakes, or reservoirs is used instead of the water to be treated, it has the advantage of eventually combining with the polluted water to be treated to create clean mixed water. Furthermore, this process is not merely a mixing step; it offers the dual benefit of utilizing the relatively clean, unpolluted water from external rivers, streams, lakes, or reservoirs as a potential energy source to rotate a water wheel.

[0110] As can be seen in FIGS. 15 and 16, the above embodiment of the present invention additionally forms a water pump (500) connected to an external pipe (501) through which relatively clean water is introduced from the outside into a water tank (302), so that relatively clean water from the outside is stored in the water tank, and the stored water falls through the water pipe (301) to perform the function of turning a water wheel.

[0111] If relatively clean water is continuously supplied from the outside, it can be continuously dropped through the water pipes to rotate the water wheel without the need to temporarily store water in a water tank.

[0112] As described above, when purifying rivers or lakes, if the water wheel is rotated using relatively clean water flowing in from the outside rather than the water to be treated, the function of the air bucket section allows oxygen from the air to dissolve into the river or lake being treated, while the relatively clean water from the outside is simultaneously introduced and mixed. This offers the advantage of purifying the river or lake in a short period of time.

[0113] If a water wheel is turned using relatively clean water flowing in from the outside, and the elevation of the water flowing in from the outside is higher than the height of the water tank, the water can flow directly into the water tank through the external pipe (501) without a water pump (500), so the implementer can design a structure to draw in water flowing in from the outside appropriately according to the elevation of the place where the water quality is to be purified.

[0114] Another embodiment of the present invention is described below.

[0115] In the present invention, it was previously explained that the water wheel is rotated by the force of falling water from the water tank. However, if the water pump for lifting water into the water tank malfunctions or is unable to perform its function, as can be seen in FIG. 17, the water wheel may be rotated by temporarily connecting a motor (600) to the rotation shaft of the water wheel.

[0116] As shown above, when rotating the water wheel, the structure of the water receiving part (111) is not required in the water wheel structure. Therefore, as can be seen in FIG. 1 (b) and FIG. 18, the water receiving part (111) can be designed as a detachable structure that can be removed from the water wheel, thereby reducing the resistance of the water and the water receiving part colliding when the water wheel rotates, and leaving only the air bucket part (112) in the water wheel so that the operation and effect of the air bucket part can be displayed.

[0117] In the embodiment in which the motor is connected to the rotation shaft of the water wheel as described above to rotate the water wheel, the configuration of the water tank (302), water pipe (301), etc., which are required when water falls to rotate the water wheel as described above, is not needed, so the structure of the barge becomes simpler.

[0118] Even if the water wheel is rotated by connecting it to the rotation shaft of the water wheel using a motor in the embodiment of the present invention, since the water tank (302), water pipe (301), etc., required for rotating the water wheel by water falling in the conventional form are basically installed on the barge, when the water pump operates smoothly, the water wheel can be rotated using oxygen from the air and relatively clean water from the outside as described above. Therefore, in such a situation, it is of course possible to install the water receiving part (111), which had been separated and removed, back onto the water wheel to rotate the water wheel.

[0119] Another embodiment of the present invention is described below.

[0120] In the present invention, as can be seen in FIGS. 19 and 20, a wind power drive (700) is installed on a barge, and when the wind power drive rotates due to the power of the wind, this rotating power can be used to rotate the water turbine by connecting the power transmission shaft (701) to the rotation shaft (113) of the water turbine.

[0121] In relation to the above embodiments of the present invention, the principle of wind power generation, such as using power generated from a wind turbine to rotate a generator, is widely known. Furthermore, since the principle and mechanical structure of connecting the power generated from the wind turbine to the power transmission shaft and the rotation shaft of the turbine to rotate the turbine are known technologies, their structures are not described in detail here.

[0122] In the above embodiment, when rotating the water wheel, the water receiving part is not required, just as in the case where the water wheel is rotated using a motor as explained earlier.

[0123] In the above embodiment, the configuration of the water tank (302), water pipe (301), etc., which is required when the water falls and rotates the water wheel as described above, is not needed, so the structure of the barge becomes simpler.

[0124] Even if the water wheel is rotated by connecting the rotation shaft of the water wheel using a wind power drive (700) in the embodiment of the present invention, since the water tank (302), water pipe (301), etc., required for rotating the water wheel by water falling in the conventional form are basically installed on the barge, when the water pump operates smoothly, the water wheel can be rotated by injecting oxygen from the air and using relatively clean water from the outside as described above. Therefore, in such a situation, it is of course possible to rotate the water wheel by reinstalling the water receiving part (111) that had been separated and removed onto the water wheel.

[0125] The excellent operation and effects according to the embodiments of the present invention are described below.

[0126] When the water wheel according to the present invention is continuously rotated, waves are continuously generated in a river or lake.

[0127] Since these wave patterns have the function of preventing water from freezing in winter, the present invention, by utilizing an air bucket to rotate a water wheel, has the advantage of continuously supplying oxygen to the water in aquaculture farms in an environment where the water does not freeze even during winter.

[0128] The present invention relates to a water purification device utilizing the aeration function of a water wheel and is an invention available for industrial application.
