DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a mixer-type algaecide device according to the present invention will be described in detail with reference to the accompanying drawings.

2 and 3 are a front view and a rear view of a mixer-type algaecide device according to the present invention, and FIG. 4 is a cross-sectional view of a mixer-type algae removing device according to the present invention. Fig. 3 is an exploded perspective view of a body and a spiral blade included in the removal device.

The mixer-type algaecide device according to the present invention is for removing algae contained in water, and is equipped not only with algae but also with a physical filtering function to filter foreign substances such as suspended substances and contaminants contained in water And also has a biological filtering function to remove the algae more efficiently and environmentally friendly.

That is, the mixer-type algaecide device according to the present invention includes a chamber 100 in which water is filled, water (hereinafter abbreviated as 'polluted water') containing algae and foreign matter through a polluted water supply pipe 510 A driving motor 400 that rotates the body 200 along the longitudinal center axis of the body 200 to rotate the body 200 and a driving motor 400 installed inside the body 200 to rotate the body 200. [ And a spiral blade 300 for discharging foreign substances present inside the body 200 to the outside of the body 200 as basic components.

The body 200 includes a skeleton frame 210 mounted in the chamber 100 to allow water to flow in and out of the inner space and rotatable about a central axis in the longitudinal direction of the body 100, And a filter cloth 220 surrounding the side surface. The driving motor 400 for rotating the body 200 is installed outside the chamber 100 and the driving shaft penetrates the side wall of the chamber 100 and is coupled to the skeleton frame 210. At this time, the water filled in the chamber 100 does not flow out through the portion of the side wall of the chamber 100 through which the drive shaft of the drive motor 400 passes, A sealing unit is provided at the penetrating portion.

When the body 200 is mounted in the chamber 100, one side in the longitudinal direction (left side in FIG. 1) is immersed in the water in the chamber 100 and the other side in the longitudinal direction (right side in FIG. 1) When the filter 200 is rotated by the driving motor 400, the contaminated water supplied to the inside of the body 200 is subjected to physical filtration while passing through the filter cloth 220. The foreign matter and the algae contained in the contaminated water are accumulated in the body 200 and the foreign matter and the algae contained in the contaminated water are accumulated in the spiral blade 300, And is transported through the foreign matter collecting pipe 520. [0050]

In this embodiment, the body 200 is inclined obliquely to one side so that the foreign substance inside the body 200 can be easily discharged to the outside of the body 200. Even if the body 200 is not inclined, The body 200 may be mounted in a vertically erected structure as long as foreign substances in the body 200 can be discharged to the outside by the spiral blade 300. However, if the central axis of the body 200 and the spiral blade 300 are vertically erected, the foreign body can not be smoothly discharged by the spiral blade 300, And it is preferably installed at an angle to the upper surface of the side wall of the chamber 100. At this time, when the inlet frame 212 directly contacts the upper surface of the side wall of the chamber 100, frictional force between the inlet frame 212 and the side wall is greatly generated when the body 200 rotates, so that the body 200 may not rotate smoothly Therefore, it is preferable that one or more rollers 110 are provided on the upper surface of the side wall of the chamber 100 where the inlet frame 212 is mounted.

The spiral blade 300 is formed in a spiral shape surrounding the rotation axis of the skeleton frame 210 and is coupled to the inner side surface of the skeleton frame 210. The spiral blade 300 has a non- That is, a coil spring shape. Therefore, the contaminated water supply pipe 510 is installed to supply the contaminated water to the central axis of the helical blade 300, that is, the hollow portion.

Although only one spiral blade 300 is provided in this embodiment, the spiral blades 300 may be arranged in two or more rows. The spiral blade 300 for transferring the solids having particles having a predetermined size in one direction has been manufactured in various shapes and structures in the related art to be commercialized, Detailed description of the detailed structure and operation principle is omitted.

The filter cloth 220 surrounding the skeleton frame 210 is made of a fabric having a void such as a nonwoven fabric and is immersed in the water filled in the chamber 100 while being rotated along the skeleton frame 210, As the supply of moisture and oxygen continues, biologically filtered microbes grow to remove algae from the water. Therefore, in the mixer-type algaecide device according to the present invention, the polluted water passing through the filter cloth 220 is not only physically filtered but also biologically filtered, so that the algae contained in the polluted water can be effectively removed .

At this time, the aerobic microorganism can be normally grown only when oxygen is sufficiently supplied. However, oxygen may not be sufficiently supplied to the filter fabric 220 by merely extracting the filter fabric 220 onto the water surface filled in the chamber 100. Accordingly, the mixer-type algaecide device according to the present invention includes an air supply pipe 600 for spraying compressed air to a submerged portion of water in the chamber 100 of the filter cloth 220 so as to supply sufficient oxygen to the filter fabric 220 ) May be additionally provided.

As described above, the air supply pipe 600 is configured to uniformly jet the high-pressure compressed air supplied from the air compressor 620 to the filter cloth 220 side through the plurality of air injection nozzles 610, Oxygen can be supplied during the time it is placed on the surface of the water as well as while it is immersed in water. Therefore, aerobic microorganisms can be more actively grown on the filter fabric 220. At this time, although only the case where the air supply pipes 600 are arranged in two rows is shown in this embodiment, the air supply pipes 600 may be arranged in one column or three or more columns according to the required oxygen amount.

In addition, foreign matter and algae are filtered during the passage of the polluted water into the body 200. As the operation period is long, a large amount of foreign matter and foreign matters are accumulated on the inner side of the filter cloth 220 Birds will accumulate. If the foreign matter and the algae are accumulated on the inner surface of the filter cloth 220 to a certain level or higher, the air gap of the filter cloth 220 is filled up, so that the physical filtering performance of the filter cloth 220 is deteriorated and the growth of aerobic microorganisms is difficult .

The mixer-type algaecide device according to the present invention is preferably constructed to have a backwash function so as to eliminate the foreign matter and algae stacked on the inner surface of the filter fabric 220 in order to solve the above problems. That is, the mixer-type algaecide device according to the present invention may include a reverse water supply line 700 for spraying reverse water in a portion of the filter cloth 220 exposed above the water surface in the chamber 100. The backwash water supply pipe 700 injects the high-pressure compressed water supplied through the pump 720 through the plurality of reverse water spray nozzles 710 so that the foreign matter and the algae stacked on the inner side of the filter cloth 220 So that it can be dropped.

The mixer-type algaecide device according to the present invention includes a return pipe 550 for supplying water in the chamber 100 to the pump 720 so that the water filled in the chamber 100 can be used as backwash water . Since the backflow pipe 550 and the pump 720 are provided, backwashing can be performed even if no separate water is supplied from the outside, so that the water consumption can be reduced and the internal structure can be simplified.

On the other hand, the filtered water filtered through the filter cloth 220 is filled in the chamber 100, and the filtered water in the chamber 100 may contain some foreign matter or sediment. Therefore, the filtered water discharge pipe 530 for discharging the filtered water in the chamber 100 is installed at a position spaced upward from the bottom surface of the chamber 100, and the inlet of the filtered water discharge pipe 530 is arranged And a plurality of V-shaped notches 532 are formed at an inlet-side end of the filtered water discharge pipe 530. When a plurality of V-shaped notches 532 are formed at the inlet end of the filtered water discharge pipe 530, even if floating matters exist on the water surface of the filtered water in the chamber 100, (532) and is prevented from flowing into the filtered water discharge pipe (530).

A drain pipe 540 is installed on the bottom surface of the chamber 100 to discharge the deposit to the outside of the chamber 100 when the deposit is accumulated on the bottom of the chamber 100 above the reference value. The drain pipe 540 is normally closed and is only opened while cleaning the inside of the chamber 100 or discharging the sediment. The drain pipe 540 is substantially the same as the conventional water tank or the like And the drain pipe 540 will not be described in detail.

The skeletal frame 210 included in the present invention has sufficient internal space to allow the spiral blade 300 to be mounted therein so that the contaminated water supplied to the inside can be smoothly discharged to the outside through the filter cloth 220 , And a plurality of openings on the side wall. The skeleton frame 210 includes a plate-shaped bottom plate 211, a ring-shaped inlet frame 212 spaced upward from the bottom plate 211 in parallel to the bottom plate 211, And a plurality of longitudinal frames 213 and a transverse frame 214 arranged to surround the space between the frames 212. [

At this time, when the opening is formed in the bottom plate 211, the contaminated water supplied to the inside of the skeleton frame 210 can flow out into the chamber 100 without passing through the filter cloth 220. Therefore, It is preferable to form the plate-like plate shape as shown in the example.

5, when the sidewalls of the skeleton frame 210 are formed of the longitudinal frame 213 and the transverse frame 214, the size of the opening formed in the sidewall of the skeleton frame 210 is maximized It is possible to maximize the filtration efficiency as well as to reduce the weight of the skeleton frame 210 and to minimize the power required to rotate the body 200.
