(54) DEVICE FOR EXTRACTION OF ALGAE

one

The invention relates to the fishing industry, in particular to devices for the extraction of algae.

A device for the extraction of algae is known; it includes a mesh conveyor belt with fixtures across it, which are attached to them, which are installed at a distance from one another, and are equipped with supporting sprockets, traction sprockets, a receiving conveyor and a resetter located at the output section of the mesh conveyor belt. tape transversely to its longitudinal axis, while the ejector is formed from sprockets mounted on a shaft with a gap for the passage of catching devices, and each of the latter is made in Ide comb with a tooth mi wedge-shaped, sharpened under the knife. The device allows a continuous process of extraction of most species of algae of industrial importance, in particular kelp, phyllophor, etc. 1.

However, the device has drawbacks that reduce the efficiency of lifting cut and trapped algae processes.

from water on board the carrier ship of the device and removal of algae from the conveyor belt and working devices and overload them to the receiving conveyor. In the first case, when the conveyor belt leaves the water and

5 due to centrifugal forces, part of the algae falls off the working devices and falls back into the water, and in the second the diverter does not fully remove the algae

10 from the conveyor belt and working devices and overload them to the receiving conveyor. At the same time, part of the algae is wound on the ejector, crushed by the ejector and falls back into the water in the gap between the working devices.

15 and receiving conveyor. Moreover, the large gap between the working devices and the receiving conveyor is caused by the angle of deviation of the conveyor belt running down into the water due to hydrodynamic resistance forces, which tend to deflect the branch each time in the direction of the receiving conveyor (the stern of the vessel). The purpose of the invention is to ensure complete removal of the cut algae and thereby prevent their loss during overload. This is achieved by the fact that it is equipped with an additional inclined plate conveyor mounted between the conveyor belt and the receiving conveyor, while the conveyor belt in the area of the plate conveyor has a bend, and the dumper consists of two collectors with nozzles for supplying water jets located above and below the conveyor belt taped. FIG. 1 shows a device for the extraction of algae, a side view and node 1; in fig. 2 - section of the conveyor belt in the section, side view. The device is mounted on a vessel 1 (Fig. 1) of a catamaran type between the hulls of the latter and contains a mesh conveyor belt 2 with catching devices 3, traction sprockets 4, support roller 5, stretching sprockets 6, limiting asterisks 7, a resetter located on the output the end of the conveyor belt, consisting of two collectors with nozzles 8 for supplying water jets, an inclined plate conveyor 9, a receiving conveyor 10 and a baffle sheet 11. The plate conveyor 9 is located between the conveyor belt 2 and the receiving a conveyor belt 10. Tightening sprockets 6 are located below the water level and are connected to a crosspiece 12 mounted in guides 13 and connected by a cable 14 to a traction mechanism 15. Conveyor belt 2 has a bend formed by sprockets 4 in the area of the plate conveyor 9 , 7 and roller 5. Restrictive asterisks 7 are placed under the traction stars 4 so that the conveyor belt 2, bending around the asterisks 7, thereby eliminates the deviation in this area of the descending branch of the conveyor belt 2 towards the inclined plate conveyor 9 (towards the stern of the vessel). In this case, the conveyor belt 2 includes two lamellar traction chains 16 (see Figs. 1 and 2) with extended inner plates 17 interconnected at a distance by fixing devices 3 and axes 18, between which there is a wire along the length of the tape. 19 forming a mesh web. In order to more effectively remove algae from the conveyor belt and catching devices 3 with water jets, it is advisable to place one collector with nozzles 8 on the inside of the conveyor belt 2 in the area of its bend on traction sprockets 4, and the second in the same area but above the conveyor belt tape 2, and the lower end of the inclined plate conveyor 9, it is advisable to place under the bend, as shown in FIG. 1. The device operates as follows: during the course of the vessel 1, the algae are cut off and caught by devices 3 located on the sagging part of the conveyor belt 2 and climbed onto the vessel. The depth of the sagging part of the conveyor belt 2 and the catch devices 3 is controlled by moving the stretching sprockets 6 along the vessel in the guides 13. At the same time, the counter-flow of water keeps the cut algae on the fixtures 3 and the ascending branch of the conveyor belt 2 until it turns to stretch Asterisks 6 and out of the water at an angle, precluding the subsequent decline of algae back into the water. Algae from the conveyor belt 2 and devices 3 are overloaded on the inclined plate conveyor 9 by water jets coming out of the collector nozzles 8, and the algae are loaded from the inclined plate conveyor 9 onto the receiving conveyor 10 by their free fall due to gravitational forces The invention will improve the efficiency of the extraction of algae by 50-60% in comparison with known devices. Claims An apparatus for extracting algae, comprising a mesh conveyor belt with securing fixtures across it, a receiving conveyor and a dumper fixed on the output conveyor belt, characterized in that in order to ensure complete removal of the cut algae and to prevent their losses during overload It is equipped with an additional inclined plate conveyor mounted between the conveyor belt and the receiving conveyor, while the conveyor belt in the area of The plate conveyor has a bend, and the ejector consists of two headers with nozzles for supplying water jets located above and below the conveyor belt.
