Description

{Algae Removing Apparatus}

More particularly, the present invention relates to an algae removing apparatus capable of efficiently removing algae without ecological contamination due to a coagulant by sucking and filtering algae such as green tide or red tide floating in surface water in a lake or a river .

In recent years, due to rapid population growth and rapid industrialization, pollutant emissions and fertilizer usage have soared, and water pollution of rivers and lakes has been intensified. Furthermore, red tides and green tides due to eutrophication of rivers and lakes have occurred, It is hindering the environment.

In general, red tide and green tide are mostly caused by a large amount of fish excrement and feed residue in polluted lake or river farms, and the proliferation of red tide and green tide is increased when the amount of sunshine or nutrients is high, When maintained at 20 to 25 ° C, it is massively proliferated and causes a serious problem of water pollution.

These red tides and green tides cause problems of filter paper clogging in the water treatment process, and when various red tides and green tides are generated, various toxic substances may be generated. In addition, due to depletion of oxygen in the metabolic process by microorganisms, It is urgently required to improve the water quality of the euphoric lake and rivers.

As a prior art disclosed to solve the above problems, Korean Patent Registration No. 1028175 (Apr. 21, 2011) discloses a buoyant plate installed on a ship and floating on the sea surface, and a plurality of buoyant plates A lowering means for ejecting the surface water into the lower part of the underwater and pushing out the yellowing liquid spraying device for supplying the yellowing liquid by the lowering means of the buoyancy plate, There is known a ship type red tide and algae removing device having a function of removing water.

In addition, in Patent Registration No. 1206941 (November 26, 2012), there is disclosed a first reaction tank in which a lake containing algae is introduced and an algae sulphate is added to cause a flocculation reaction with the algae, A second reaction tank which is charged with the algae and coagulated with the algae, a first settling tank into which the second reacted lake water is introduced and settled, and a second settled tank which receives the first settled treated lake water and separates and discharges the sludge by sedimentation treatment And a re-use tank which contains a tea settling tank and reuses the slaked liquor which is not dissolved in the primary settling tank into the primary tank so as to be reused, thereby improving the removal efficiency of the algae Lt; / RTI >

In addition, in the registered patent publication No. 1189746 (Oct. 11, 2012), a bubble generating / charging unit provided at the front end of the hull for traveling along a lake, a bubble generating unit for injecting the bubble into the lake by generating bubbles, A coagulant injecting unit disposed adjacent to the bubble generating / charging unit and injecting a coagulant into a region into which the bubbles are injected; and a coagulant injecting unit attached to the bottom of the hull in a region where the coagulant is charged, A mixing unit for mixing the bubbles and the flocculant introduced into the lake into the lake and rapidly mixing with the lake water to make the dissolved material into granular sludge so as to float to the upper part of the lake; A scraper unit for collecting the sludge collected by the scraper unit; And a pair of lifting units disposed on both sides of the hull and along the longitudinal direction of the hull so as to float the hull to the surface of the water. Accordingly, it is possible to prevent and alleviate algae that can secure high quality water resources An algae removal line for removal is known.

However, in the above-mentioned prior art, in the case of the Japanese Patent Registration No. 1028175, since a continuous yellowing solution is required to remove red tide and green tide, a large amount of yellowing solution is used in the operation, And furthermore, organic matter in loess becomes food of microorganisms and causes eutrophication, so that red tide and green tide are reproduced again.

In addition, in the case of the above-mentioned prior arts, 1206941 and 1189746, since separate coagulant is added to remove red tide and green tide, it is difficult to supply and receive chemicals according to a large amount of drug input, In addition to the problem of secondary contamination due to coagulant application, it causes ecotoxicity and the government prohibits the use of coagulant. Therefore, additional work is required to remove dead red tide and green tide after work, which is very troublesome and time consuming .

The suction module 110 is positioned on the water surface so as to contact the surface waters containing algae, and is submerged to a certain depth (for example, 5 to 10 cm) toward the water from the water surface.

The suction module 110 may have a plate-like or cylindrical structure.

The drive pump 130 drives the suction module 110 to generate a suction force. That is, since the suction force is generated in the suction module 110 by driving the drive pump 130, the surface layer water containing algae is sucked.

The driving pump 130 and the suction module 110 are structured to communicate with each other through a suction pipe 120.

The driving pump 130 may be integrally formed on the suction module 110 of the suction unit 100 and may be disposed at a distance from the suction module 110 and may be connected to the suction pipe 110 through the suction pipe 120 It is also possible to constitute the filter unit 200 as a separated type having a structure in which it is located close to the filter unit 200.

The suction frame 113b may have a plurality of suction frames 113b having different diameters at regular intervals inward / outward.

The suction module 110 may be integrally formed with the drive pump 130. That is, it is preferable that a more powerful suction force is applied to the suction hole 115b as the drive pump 130 is mounted on the upper portion of the water guide bracket 111b.

The suction unit 100 may further include position adjusting means 119 for adjusting the suction position (height and height) of the suction frame 113b of the suction module 110 according to the water surface position under water to be operated It is possible.

The position adjusting means 119 is provided on the water guide bracket 111b and includes a fixed frame 119a, a rotating screw 119b and a guide rod 119c.

The fixed frame 119a is installed at a position above the suction module 110 with a gap therebetween and is fixed to a position where the suction unit 100 is to be mounted and the rotating frame 119b and the guide rod 119c, And constitutes the overall configuration of the suction unit 100 to be supported.

The rotary screw 119b is rotatably screwed on the fixed frame 119a and the upper part of the suction module 110 is coupled to the lower end of the rotary screw 119b. That is, the water guide bracket 111b and the suction frame 113b of the suction module 110 are formed to be vertically movable according to the rotating direction of the rotating screw 119b.
