Abstract

PURPOSE:To cultivate a large amount of a diatom in space, by setting detachably a great number of collectors in a multi-layer state in space in a chamber, sprinkling a culture solution on the collectors by a water sprinkling machine, filtering the dropped culture solution and feeding it to the water sprinkling machine. CONSTITUTION:The culture solution feeder 5 is operated, a culture solution is sprayed from the water sprinkling machine 4 and the culture solution is sprinkled on the surfaces of the collectors 3. The culture solution is dropped while cultivating gradually a diatom attached to the collectors 3, dropped on the after-floor surface 7 and collected in the tank 6. An unnecessary diatom, miscellaneous marine algae, spores, etc., are removed by the filter 5a and sent by pressure to the water sprinkling machine 4 by the pump 5b again.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a culturing device for diatoms that serve as separation feed for snails such as abalones and crawling animals such as sea cucumbers, and particularly relates to a culturing device for culturing diatoms in the air. This invention relates to a diatom spray culture device.

[Conventional technology]

In the aquaculture production process of snails such as abalone and crawling animals such as sea cucumbers, diatoms are used as feed. Conventionally, diatoms are cultured by attaching them to a collector using a corrugated vinyl plate, but two commonly used methods are one by fertilization management in land aquariums and the other by natural propagation in the natural sea. There is.

[Problems to be solved]

In the conventional diatom cultivation methods mentioned above, the former cultivation method requires large equipment and has the problems of relatively difficult control of conditions such as water temperature, while the latter cultivation method is difficult to adapt to natural conditions. The problem was that it was easily influenced and it was difficult to maintain stable production. Furthermore, this has also resulted in secondary problems such as a shortage in the supply of diatoms and an increase in costs.

[Means for solving problems]

The diatom spray culture device of the present invention has been made to solve the above problems, and includes a large number of collectors arranged in multi-layers in a detachable manner in the air indoors, and a water sprinkler that sprays culture solution onto the collectors. The system is constructed with a culture solution supply device that is installed near the top of the collector, and further includes a culture solution supply device that filters the culture solution dripping from the collector and supplies it again to the water sprinkler. and,
With this configuration, diatoms can be stably cultured in large quantities in the air without using an aquarium.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

Figure 1 is a front sectional view of the entire device, and Figure 2 is A-A in Figure 1.
A sectional view taken along line A is shown.

In these drawings, 1 is a simple house made of aggregate and at least a transparent material at the roof. Reference numeral 2 denotes pillars, and a plurality of pillars are installed inside the simple house 1 on two levels at the bottom of the hill. 3 is a collector with a hole 3a at the upper end.
is provided, and the support pillar 2 is passed through the support pillar 2 and suspended from the support pillar 2. This collector 3 is detachable and movable from the support 2, and a large number of collectors 3 are suspended from the wooden support 2. Since the pillars 2 are installed in two layers, upper and lower, the collectors 3 are arranged in two layers in the simple house 1.

4 is a water sprinkler, and a plurality of water sprinklers are installed near a part of the collector 3 in a direction perpendicular to the arrangement direction of the collector 3 to the pillars 2. This water sprinkler 4 is formed by providing a large number of spray holes at appropriate positions on the circumferential surface of a pipe. Reference numeral 5 denotes a culture fluid supply device, which is composed of a filter 5a and a pump section 5b. The filter 5a is installed in a tank 6 provided on a part of the indoor floor 7 of the 1wN easy house l, and the pump part 5b is
The culture solution sucked through the filter 5a is pumped to each water sprinkler 4.

In addition, the indoor floor of the simple house 1 is slightly sloped down toward the tank 6 installed in a part of the house, so that the culture solution dripping onto the floor 7 can be collected in the tank 6. .

Therefore, when the culture solution supply device 5 is operated and the culture solution is sprayed from the sprinkler 4, the culture solution sprinkles on the surface of the collector 3 and flows down while gradually cultivating the diatoms attached to the collector 3. The culture solution that dripped onto the floor surface 7 after flowing down the surface of the collector 3 is collected in the tank 6, and after removing unnecessary silicon, seaweed, spores, etc. with a filter 5a, it is passed through the pump 5b again. The water is fed under pressure to the water sprinkler 4.

In addition, the amount of culture solution sprayed from the water sprinkler 4 to the collector 3,
! The degree, temperature, etc. may be controlled by installing these controllers in the culture solution supply device 5 (not shown), and it is also possible to control them using a computer.

Furthermore, the diatom spray culture apparatus of the present invention is not limited to the above-mentioned embodiments, but includes, for example, the following modifications.

(1) The collector should be arranged in multiple layers with three or more stages.

(2) Change the shape of the collector to another shape, for example, to a shape with a large surface area.

(3) Install the sprinkler in the same direction as the collector arrangement or diagonally.

(4) Use a one-way sprinkler system or another type of water sprinkler.

(5) Control the temperature inside the simple greenhouse.

〔Effect of the invention〕

According to the diatom spray culture device of the present invention configured as described above, the following effects are achieved.

(1) Huge aquarium equipment etc. are not required.

(2) Since the cultivation is carried out in the air and requires only a small amount of culture solution, various conditions can be controlled and water quality can be easily and quickly controlled.

(3) Since it is easy to control various conditions and manage water quality, it is possible to improve culture efficiency and also to perform single-species, pure culture.
