It should be noted that in the drawings, the same members are denoted by the same reference numerals. Detailed descriptions of well-known functions and constructions which may be unnecessarily obscured by the gist of the present invention are omitted.

1 is a side sectional view showing a side structure of a plankton cultivation apparatus 100 according to the present invention.

As shown in the figure, the plankton culture apparatus 100 according to the present invention includes a raw water separation tank 110 into which raw water is introduced and separated into phytoplankton and zooplankton, A zooplankton culture tank 130 provided at a lower portion of the phytoplankton culture tank 120 for culturing zooplankton and a zooplankton culture tank 130 coupled to a lower portion of the zooplankton culture tank 130, A sludge collecting pipe 140 for collecting the sludge A generated in the incubation tank 130 and discharging the sludge to the outside and a sludge collecting pipe 140 connected to the bottom of the zooplankton culture tank 130, And a sludge discharge cap 150 discharging the sludge.

Here, the raw water separation tank 110, the phytoplankton culture tank 120, and the zooplankton culture tank 130 are arranged in a stacked manner. And a phytoplankton culture tank 120 and a raw water separation tank 110 are arranged in this order on the lowermost portion. Thus, phytoplankton and zooplankton are supplied from the upper part to the lower part. Since the plankton culture apparatus 100 is formed by the multi-layer lamination method, the installation area can be minimized.

The raw water separating tank (110) is provided on the upper part of the phytoplankton culture tank (120). The plurality of raw water separators 110 may be used together or alternatively. A raw milk infusion inlet 111 to which raw water is supplied is connected to one side of the raw water separation tank 110. The raw milk feed pipe 111 receives raw water from a lake, a reservoir, a fresh water lake, etc. through a raw water pump (not shown).

A phytoplankton supply pipe 113 for supplying phytoplankton to the phytoplankton culture tank 120 in a direction opposite to the raw milk feed pipe 111 is formed. Although not shown in the drawing, a partition wall (not shown) and a separation membrane (not shown) are disposed in the raw water separation tank 110. The membrane (not shown) separates phytoplankton and zooplankton from the raw water. The raw water passed through the partition wall (not shown) passes only the phytoplankton through the separation membrane, and the zooplankton remains in the raw water separation tank 110. The phytoplankton that has passed through the separation membrane (not shown) is supplied to the phytoplankton culture tank 120 through the phytoplankton supply pipe 113.

The zooplankton which has not passed through the separation membrane (not shown) is supplied to the zooplankton culture tank 130 through the zooplankton supply pipe 115 connecting the raw water separation tank 110 and the zooplankton culture tank 130.

The phytoplankton culture tank 120 is provided between the raw water separation tank 110 and the zooplankton culture tank 130. The phytoplankton culture tank 120 receives the phytoplankton from the phytoplankton supply pipe 113, explosively increases the population, and supplies the phytoplankton to the phytoplankton culture tank 130. The phytoplankton culture tank 120 and the zooplankton culture tank 130 are connected via a connection pipe 121, and phytoplankton is supplied.

The zooplankton culture tank 130 cultivates zooplankton and discharges the zooplankton to the outside. 2 is a perspective view showing the structure of the zooplankton culture tank 130 according to the present invention.

The zooplankton culture tank 130 includes a culture tank main body 131 in which the number of zooplankton cultures W is accommodated, an overflow pipe 133 and 135 at an upper portion of one side of the culture tank main body 131, And a sludge discharge hole 137 formed through the bottom surface of the sludge discharge pipe 131 and coupled to the sludge discharge cap 150.

The upper part of the culture tank main body 131 is structured so as not to be exposed to sunlight. The culture tank main body 131 is formed to have a constant volume. At this time, the bottom surface of the culture tank main body 131 is formed to be inclined outward from the center as shown in Fig. Whereby the animal plankton carcass can be concentrated to the lowest center. A sludge discharge hole 137 is formed in the center area of the bottom surface to guide sludge such as carcass of zooplankton to the sludge discharge cap 150.

On the other hand, a discharge pipe 135 is provided at one side of the culture tank main body 131. The discharge pipe 135 discharges the zooplankton in the culture tank 131 to the outside.

The sludge collecting pipe 140 is connected to the lower part of the zooplankton culture tank 130 to collect sludge such as animal plankton carcass and discharge it to the outside. The sludge collecting pipe 140 is provided with a tube having a semicircular cross section. The upper portion of the sludge collecting pipe 140 is open and is coupled to the bottom surface of the culture tank main body 131. At this time, the sludge collecting pipe 140 is arranged to communicate with the sludge discharge hole 137.

At one end of the sludge collecting pipe 140, an exhaust pipe 141 for discharging the odor and gas generated inside is extended upward. A sludge discharge valve (143) is provided at the other end of the sludge collecting pipe (140) to collectively discharge the collected sludge to the outside.

The operator can open the sludge discharge valve 143 at predetermined intervals to discharge the collected sludge to the outside.

The sludge discharge cap 150 is connected to a sludge discharge hole 137 of the culture tank main body 131 to discharge sludge such as animal plankton bodies suspended in the culture liquid W and excretion to the sludge collecting pipe 140.

The sludge discharge cap 150 includes a cap body 151 disposed on the upper surface of the sludge discharge hole 137 as shown in FIGS. 2 and 3, And a sludge guide pipe 153 for guiding the sludge to the sludge pipe 140.

The cap body 151 is formed of a plate-like material having an area capable of covering the sludge discharge hole 137. [ The cap body 151 has an area that can be seated in the sludge discharge hole 137. At this time, a plurality of discharge ports 151a for discharging the sludge to the sludge collecting pipe 140 are formed in the plate surface of the cap body 151. The outlet 151a is sized to pass through the sludge and not through the zooplankton.

The discharge port 151a is formed only in the remaining area except for the guide tube coupling area 151b in the center area of the cap main body 151. [ A coupling surface 153a of the sludge guide pipe 153 is coupled to the lower portion of the guide tube coupling region 151b. Since the engaging surface 153a is hermetically closed, the discharge port 151a is formed in an area excluding the guide tube engaging area 151b.

The sludge guide pipe 153 is integrally coupled to the lower surface of the cap body 151. The sludge guide pipe 153 is formed in a rectangular shape in cross section, and its area gradually increases from the upper part to the lower part. The sludge guide pipe 153 is formed in a trapezoidal shape when viewed from the front. The coupling surface 153a formed on the upper surface of the sludge guide pipe 153 is integrally coupled to the lower surface of the guide tube coupling area 151b of the cap body 151. [

The sludge guide pipe 153 is provided so that both the engagement surface 153a and the lower surface 153b are sealed. The sludge in the sludge collecting pipe 140 is prevented from flowing into the sludge discharge hole 137 through the inside of the sludge guide pipe 153.

That is, as shown in FIG. 4, the sludge A is moved to the sludge collecting pipe 140 through the outlet 151a of the cap body 151. At this time, the discharged sludge (A) moves along the inclined surface of the sludge guide pipe (153) and moves to the lower side of the sludge collecting pipe (140). The sludge A in the sludge collecting pipe 140 is blocked from moving to the discharge port 151a by the moving pressure of the sludge A flowing downward through the discharge port 151a. Also, the lower surface 153b of the sludge guide pipe 153 is blocked, and the backward flow of the sludge through the sludge guide pipe 153 to the discharge port 151a is also blocked.

The sludge in the zooplankton culture tank 130 can be naturally trapped in the sludge collecting pipe 140 through the sludge discharge cap 150 and the collected sludge A is returned to the inside of the culture tank main body 131 So that the zooplankton culture tank 130 can be managed cleanly.

The operation of the plankton cultivation apparatus 100 according to the present invention having such a configuration will be described with reference to FIGS. 1 to 4. FIG.

Raw water of the lake is introduced into the raw water separating tank 110 through the raw water inflow inlet 111 through a raw water pump (not shown). The phytoplankton contained in the raw water is supplied to the phytoplankton culture tank 120 through a phytoplankton pipeline 113 through a separation membrane (not shown). The phytoplankton is cultivated in the phytoplankton culture tank 120 to increase its population and is supplied to the zooplankton culture tank 130 through the connection pipe 121.

The zooplankton that has not passed through the separation membrane (not shown) remains in the raw water separation tank 110 and is supplied to the zooplankton culture tank 130 through the zooplankton supply pipe 115. The zooplankton contained in the zooplankton culture tank 130 is fed with the phytoplankton supplied through the connection pipe 121 to increase its population.

And the culture water overflowing in the zooplankton culture tank 130 is discharged to the outside through the overflow pipe 133 because it is supplied in a continuous batch manner. At this time, a blocking film (not shown) is provided in front of the overflow pipe 133 to block the discharge of the zooplankton to the overflow pipe 133. Since the zooplankton does not pass through the barrier (not shown), the density of the zooplankton in the zooplankton culture tank 130 increases and becomes concentrated after a certain period of time.

When the population of zooplankton is cultured above the reference value, the discharge pipe 135 is opened to discharge the zooplankton culture water to the outside.

On the other hand, the bottom of the zooplankton culture tank 130 has a low height at the center and an inclined height to be gradually elevated to the outside, so that sludge such as animal carcass of plankton and manure are concentrated at the center.

The sludge A is discharged to the sludge collecting pipe 140 through an outlet 151a formed in the cap body 151 of the sludge discharging cap 150 as shown in FIG. At this time, the discharged sludge (A) moves along the inclined surface of the sludge guide pipe (153) and moves to the lower side of the sludge collecting pipe (140). The sludge A in the sludge collecting pipe 140 is blocked from moving to the discharge port 151a by the moving pressure of the sludge A flowing downward through the discharge port 151a. Also, the lower surface 153b of the sludge guide pipe 153 is blocked, and the backward flow of the sludge through the sludge guide pipe 153 to the discharge port 151a is also blocked.

The sludge in the zooplankton culture tank 130 can be continuously collected by the sludge collecting pipe 140 through the sludge discharge cap 150 and the collected sludge A is collected into the culture tank main body 131 So that the zooplankton culture tank 130 can be managed cleanly.

Since the zooplankton B is larger than the discharge port 151a, the zooplankton B remains in the culture tank main body 131 without being discharged to the discharge port 151a.

The sludge A collected in the sludge collecting pipe 140 is discharged periodically by opening the sludge discharge valve 143.

As described above, the plankton culture apparatus according to the present invention includes a sludge collection pipe for collecting sludge at the lower part of the zooplankton culture tank, and a sludge discharging pipe for discharging sludge only to the sludge collecting pipe between the sludge collecting pipe and the zooplankton culture tank A cap is provided.

The embodiments of the plankton culture apparatus of the present invention described above are merely illustrative and those skilled in the art will appreciate that various modifications and equivalent embodiments can be made without departing from the spirit and scope of the invention. It will be possible. Therefore, it is to be understood that the present invention is not limited to the above-described embodiments. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims. It is also to be understood that the invention includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
