The invention relates to the fishing industry, namely to the cultivation of marine organisms, mainly mollusks.

The aim of the invention is to provide optimal temperature conditions for the cultivation of mollusks by ensuring the constant circulation of water during the cultivation process.

FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 is a section A-A in FIG. one.

The device contains two parallel plates 1, which are hermetically interconnected by a casing 2. In through holes 3, arranged in pairs on plates 1, pipes 4 are hermetically fixed. Casing 2 is equipped with inlet 5 and outlet 6 nozzles, by means of which the space formed The plates 1, the casing 2 and the pipes 4, are supplied and discharged, being made with double walls, the space between which is filled with air.

The internal cavity of the tubes can be used as a collector for settling the larvae and their rearing. However, in a number of cases it is advisable to use removable collectors that can be placed in the internal cavity of the pipes. As such collectors, ropes, perforated cylinders, flexible plates, mesh bags and so on can be used.

The use of the proposed device makes it possible to create and maintain 15 optimal conditions for growing mollusks, regulating the temperature regime and feeding regime, depending on the convection rate of the growing medium along the collectors. Creating optimal conditions

growing allows for improved production. To increase the buoyancy of the plantations, their profitability, and the cover 2 can also be performed with the utilization of low-grade heat discharged into reservoirs. The device is convenient to transport, compact, allows you to refuse confusing cold walls 7, the space between which is filled with air. To regulate the flow rate of the medium through the pipes 4, the device is equipped with roof covers in the form of ropes, does not require a turtleneck 8 with a hole 9 and a locking body 10 In the cavity of pipes 4, collectors 11 can be placed in the form of ropes, cylinders, flexible plates, mesh bags.

maintenance of plantations, allows to realize the technological process of processing the grown mollusks directly in the device. Lifting hot steam into the last of the water and supplying the heat carrier, instead of the heat exchanger, can reach the outer surface of the pipes, open the sinks through the sump, and the executing branch pipe supplies the heat carrier which is discharged through the discharge branch pipe. This ensures that the pipes are heated and, therefore, the water in the pipes is heated. Heated portion of water raises the collection of interstitial fluid. The removal of mollusks from the collectors can be accomplished, for example, using a jet of steam or liquid or pushing the piston through the collectors. The device can be mnos, and in its place a new one comes from the bottom - 35 is used once and for all.

When using removable collectors 11 (ropes, cylinders, flexible plates, mesh bags), they are inseminated separately, and then placed collectors 11 into the internal cavities of pipes 4. If used as collectors 11, they are beaten in the zone controlled thermal effect and circulation of seawater.

By changing the temperature of the coolant, you can adjust the flow rate of the medium along the pipes. Device supply cover

Since the device is intended to function as a submerged state in layers of water, it is necessary in this

During the operation of these stations, up to 70% of the energy they generate is lost in the form of low-grade heat, which is not used by industry.

able to maintain, for example, with the help of Koreas and floats. When using the gaseous medium as the coolant, the device itself plays the role of a float by filling the space between the casing, the plates and the collectors with gas. With the same purpose — to increase buoyancy in the case of using a heat-transfer fluid, as well as to reduce heat losses — the device’s casing can

be made with double walls, the space between which is filled with air.

The lecturers in the form of ropes, do not require diving maintenance of the plantations, allows to realize the technological process of processing the grown mollusks directly in the device. Raising the last of the water and supplying hot steam instead of the coolant, you can achieve the opening of the sinks and collect at the same time the collection of the inter-shell liquid. The removal of mollusks from the collectors can be accomplished, for example, using a jet of steam or liquid or pushing the piston through the collectors. The device may be mnomoluskov produce insemination of the internal cavities of the pipes 4 of the device, for example, by pumping water with larvae through them.

When the operation of these stations, up to 70% of the energy they produce is lost in the form of low-grade heat, which is not used by industry.

carrier. Thus, the coolant enters the space formed by the inner wall 7 of the casing 2, the plates 1 and the pipes 4, and, releasing heat to the water in the pipes 4 that it washes, is discharged through the discharge pipe 6 into the closed circulation system of the coolant. The water in pipes 4 and having a temperature higher than the temperature of the surrounding water rises, and a new portion comes from its place. As the temperature of the coolant increases, the temperature of water heating in the pipes 4 and, consequently, the speed of raising it to the upper layers increases. Thus, it is possible to regulate the flow rate of the growing medium along the collectors from 0, when the temperature of the coolant is equal to the ambient temperature, to a speed corresponding to the required temperature for heating the growing medium near the collectors. Regulating the flow rate of the medium through the collectors and the speed of its heating can not only vary the temperature of the coolant, but also by adjusting the degree of opening of the hole - 9 in the cover 8 by the locking member 10. From the state when the hole 9 is closed, there is no flow and the medium is heated collectors to the temperature of the coolant, to the state when the opening 9 is open and the flow is free, and

the speed depends only on the temperature of the coolant.
