Description

Suction duck for sludge}

The present invention relates to a drain pipe body for sucking water including bottom sludge, which is used in a farm where a water is laid.

An inland aquaculture nourishes the target species through retained water. The water quality is easily deteriorated by a variety of causes such as food supply, individual excretion and mortality, and the problems of collective mortality and growth are caused thereby, and the success of the aquaculture is greatly influenced by the water quality management from the fish to the fish .

Furthermore, in order to increase the productivity, it is necessary to densify the possible objects in the designated breeding space, thereby further increasing the cause of the deterioration of the water quality. An artificial aquaculture facility has a very low filtration capacity and should have a separate filtration facility. The filtration facility removes solid dirt and dissolved organic matter, and performs various water treatments such as pH adjustment, reduction treatment of toxic compounds such as ammonia and nitrite, and increase of dissolved oxygen.

FIG. 7 schematically shows a conventional aquaculture facility 200 and a drainage line 220. The farm site 200 has a polygonal or circular cross section and a certain depth to accommodate the water. A drain 210 for drainage is installed at the center of the farm 200. Also, although not shown, a filtration apparatus for purifying confined water is installed in the vicinity of the farm, and the water sucked through the drain line 220 is cleaned by the filtration apparatus and then returned to the farm site .

The purified water discharged from the filtration apparatus is discharged along the edge of the farm, thereby making a water flow in one direction about the center of the farm 200 as shown in FIG. This swirling flow provides an ecological environment close to nature where water flow is constantly present to the breeding individual, and it has the effect of rapidly mixing the reduced water and the existing water to prevent water stagnation in the corner.

On the other hand, the bottom of the farm 200 is flat or the center is formed to be deeply recessed as compared with the edge. The submerged sludge generated in the farm sinks on the bottom, and it naturally accumulates in the middle of the bottom center. At this time, since the bottom of the bottom is formed deep and the bottom surface has a sloping surface, even if swirling flow is always present, the bottom sloping surface is actually very gentle, so that the immersion sludge does not stick to the center of the bottom of the farm.

In the conventional art, a plurality of drainage lines 220 for drawing water into the filtration processing apparatus are installed, and the inundation port of each drainage line 220 is opened and processed in a manner that spreads the flooded sludge on the floor of the farm have.

Such conventional techniques have a disadvantage in that effective sludge suction is not achieved because the size of the farm is increased and the bottom surface on which the sludge accumulates is widened so that the submergible sludge spreads widely.

Korean Patent Publication No. 10-1996-0701797 (June, 1995)

The present invention provides a drain pipe body for effectively sucking sludge that sits on the floor of a farm.

Other objects and advantages of the present invention will become apparent to those skilled in the art from the following detailed description.

In order to solve the above problems, the present invention provides a method of manufacturing a swing structure, comprising the steps of: forming a hollow body to be used for a swinging farm, And a second suction port facing the water flow corresponding to the swirling flow is formed between the primary suction port and the body spaced apart from the primary suction port.

At this time, the secondary suction port may be provided with an inlet guide protruding from the body to guide the water passing through the secondary suction inlet to the secondary suction inlet.

On the other hand, the primary intake port faces the rotation center of the swirling flow, and the body is arranged to form a backward angle with respect to the entry direction of the swirling flow, thereby forming a water flow along the body toward the secondary intake port .

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the structure, function and operation of a sludge suction pipe according to the present invention will be described with reference to the accompanying drawings. It should be noted, however, that the drawing numbers for the same or similar components throughout the drawings and embodiments shall be used collectively.

In the following description, terms such as 'first', 'second', and the like are used to distinguish constituent elements whose technical meaning is within the same range for convenience. That is, any one configuration may be arbitrarily referred to as a 'first configuration' or a 'second configuration'.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention and, therefore, are not to be construed as limiting the technical spirit of the invention. It is to be understood that the invention is not to be limited by any of the details of the description to those skilled in the art from the standpoint of a person skilled in the art that any or all of the drawings shown in the drawings are not necessarily the shape,

1 to 5 relate to a drain pipe body for sludge suction according to the first embodiment of the present invention.

The drain pipe body 100 according to the embodiment of the present invention is used for sucking the water immersion sludge and water together in a farm having a swirl flow. The drain pipe body 100 is installed on the bottom 201 of the farm 200 and is connected to the suction pipe H. In the illustrated embodiment, the suction pipe H is made of a bendable bellows.

Although not shown, the suction pipe is connected to a fluid pump or the like which provides negative pressure. Water and submerged sludge that pass through the suction piping can be returned to the farm after removing the sludge through a separate filtration device.

The swirling flow in the farm 200 can be generated by the reduced water through the filtration device. Specifically, reduced water can flow along the wall surface of the farm to generate a swirl flow. In addition, a swirl flow can be formed through various devices such as aberration and the position of the air outlet of the air supply device.

The swirling flow is the slowest in the center of the farm 200, which is the center of rotation, and the flow rate is faster toward the edge of the farm 200. The immersion sludge is collected at the center of the bottom. Occasionally, by forming the center of the bottom concave, the immersion sludge can be better gathered at the bottom center. Even in such a case, the swirling flow is not so fast and the bottom inclination angle can not be formed very large, so that the immersion sludge is gathered in a relatively wide circular form at the center of the bottom of the farm.

3 shows a drain pipe body according to the first embodiment of the present invention.

The water pipe body 100 is formed by forming a primary inlet 11 and a secondary inlet 12 in a hollow body 10. Here, although the body 10 is shown in a rectangular shape in cross section, it may be variously changed, such as a circular shape, an elliptical shape, and the like.

The body 10 is straight and straight. There is no space between the floor of the farm 200 and the body 10 when the water pipe 100 is laid so that the bottom of the body 10 is in contact with the bottom 201 of the flat farm 200. If the bottom of the farm is formed with a gentle curved surface, the body may be curved according to the curvature of the bottom of the farm. Or a gap fill plate to fill the empty space between the bottom of the farm and the straight body.

Clamps (C), screws, etc. may be used to fix the drainage pipe body (100) to the floor of the farm site (200). Or if the water pipe body is heavy enough, its position may be fixed at the bottom of the farm with its own weight.

The primary intake port (11) is formed at the tip of the body (10). In FIG. 3, the duct 111 is formed in the primary inlet 11 so that the angle of the primary inlet 11 is slightly inclined.

The secondary suction port 12 is formed in the middle portion of the body 10. The secondary suction port 12 is spaced apart from the primary suction port 11 and is spaced a considerable distance from the distal end portion where the primary suction port 11 is formed. The distance from the primary inlet (11) to the secondary inlet (12) depends on the area where flooded sludge mainly collects on the bottom of the farm.

For example, assuming that the circular area in which the submergible sludge is collected is represented by the imaginary circle M in FIG. 4, the first inlet 11 is connected to the center of the virtual circle M, The position of the secondary suction port 12 can be made to have a length reaching the edge of the virtual circle M in a state of being arranged in the radial direction of the virtual circle M. [

Although not shown, the body is divided into a front body portion having a first inlet port and a rear end body portion having a second inlet port so as to correspond to a farm having various areas, and then the front end body is inserted into the rear end body portion So that the interval between the primary inlet and the secondary inlet can be adjusted.

On the other hand, the direction in which the secondary suction port 12 is formed is a direction facing the water flow corresponding to the swirling flow. 3 to 4, in the illustrated embodiment, the swirling flow rotates in a clockwise direction, and the drain pipe body 100 is placed at approximately 9 o'clock. As the swirling flow enters the side of the body facing the incoming swirling flow, A suction port 12 is formed. As a result, the water and the sludge, which have flowed toward the front of the secondary suction port 12 by the swirling flow, are immediately sucked into the drain pipe body 100 through the secondary suction port 12.

An inlet guide 122 is formed to protrude along the periphery of the secondary inlet through an additional construction that can be omitted so as to guide water around the secondary inlet 12 into the secondary inlet 12.

In the illustrated embodiment, the inlet guide 122 protrudes around the second half of the second inlet 12 so that the angle of the inlet of the second inlet 12 is about 45 degrees Changing.

On the other hand, FIG. 6 shows a drain pipe body 100 according to a second embodiment of a simpler shape. The drain pipe body 100 according to the second embodiment includes the technical features of the above-described first embodiment as it is within the range not to conflict with the following description.

The water pipe body 100 shown in Fig. 6 has a primary inlet 11 at the front end and a secondary inlet 12 at the side. The primary intake port 11 and the secondary intake port 12 are spaced apart from each other.

The primary intake port 11 is formed so as to be inclined with respect to the longitudinal direction of the body 10 by obliquely cutting the front end of the body 10. [ On the other hand, the second suction port 12 is not provided with an inlet guide unlike the previous embodiment, and the direction in which the second suction port 12 is opened is perpendicular to one side surface of the body 10.

Referring again to FIGS. 1 to 2 and 4, a coupler 101 connected to the suction pipe H is coupled to the rear end of the drain pipe body 100. If the body 10 has a circular cross-section, the coupler may be omitted.

On the other hand, the suction pipe H is spaced apart from the bottom 201 of the farm 200 to form a gap. In order to separate the suction pipe H from the bottom of the farm, a plurality of supports S are used.

As the suction piping H is separated from the bottom of the farm, the flooded sludge is not interfered with the suction piping H, and can continue to rotate in accordance with the swirling flow. Then, as the sludge moves circularly due to the swirl flow, the sludge gradually collects in the center of the farm.

Hereinafter, the fixing position of the drain pipe body 100 will be described. As described above, the drain pipe body 100 is fixed on the floor so as to contact with the bottom 201 of the farm site 200. At this time, the primary intake port 11 is disposed so as to face the rotation center of the swirling flow. In the drawing, a drain 210 is provided at the center of rotation. The primary intake port 11 is not directly in contact with the drain 210 but is located substantially adjacent to the drain 210.

Further, the body 10 is arranged obliquely with respect to the entry direction of the swirling flow so as to form a receding angle A with respect to the entry direction of the swirling flow. 3 and 4, when it is assumed that the flow of the swirling flow is an ideal circle, the swirling flow corresponding to the drain pipe body 100 located at the 9 o'clock position in Fig. 4 locally flows in a straight line (see Fig. 5) . With respect to the flow of this straight line, the body is arranged at a rearward angle (A). That is, the drain pipe body 100 is arranged obliquely with respect to the swirling flow.

The water and the sludge entering between the primary inlet 11 and the secondary inlet 12 are blocked by the body 10 and flow back along the inclination of the body 10 forming the backward angle A . Then enters the secondary inlet 12 and is collected into the drain pipe body 100 and sent to a separate filtering device.

At this time, since the inlet guide 122 is further formed in the secondary inlet 12, the water and the sludge flowing strongly toward the rear end of the body on the outer wall surface of the body can be completely sucked into the secondary inlet.

The body 10 is immersed in an area covering the swirling flow from the primary intake port 11 to the secondary intake port 12 in addition to the area occupied by the suction force of the primary intake port 11 and the secondary intake port 12, The sludge can be effectively sucked in comparison with the conventional technique because the sexual sludge is sucked. As a result, there is no long-term sludge remaining on the bottom of the farm, so water quality in the farm is greatly improved.
