Abstract

This publication relates to a system and a method for transporting a goods in a main liquid, causing the main liquid to flow at a velocity in a desired direction through the system, using an ejector as a driving means for creating a suction 5 upstream of the ejector inlet, wherein the flow is produced by means of an ejector (10,10') injecting a liquid into the main flow. The system comprises a first injector (10) and a second injector (10') connected in series and with a liquid take out chamber (40) arranged between an outlet of the first injector (10) and the inlet of the second injector (10'), the liquid to be injected in the second injector (10') being drawn 0 from the exit liquid from the first ejector (10).

Claims (17)

Claims
1. System for transporting a goods in a main liquid, such as fish or other types of solid articles or materials, where a suction is made upstream by a suction producing device (10), and where the suction producing device (10) causes the main liquid to flow at a velocity in a desired direction through the system, wherein the flow is produced by means of an ejector (10, 10') injecting a liquid into the main flow, c h a r a c t e r i z e d i n that the system comprises a first injector (10) and a second injector (10') connected in series and with a liquid take out chamber (40) arranged between an outlet of the first injector (10) and the inlet of the second injector (10'), the liquid to be injected in the second injector (10') being drawn from the exit liquid from the first ejector (10).
2. System according to claim 2, wherein liquid is drawn from the outlet of the first ejector (10) by a powered pump ((31 '), the withdrawn liquid being delivered as injection liquid to the second ejector (10') by the same pump (31').
3. System according to claim 1 or 2, wherein the ejector (10, 10') comprises a main tube or cylinder with an inlet, through which the primary fluid flow is flowing, ejector chamber provided with one or more peripherally opening or nozzles (26), and an outlet, the ejector chamber and openings or nozzles being associated with a pump (31 ,31'), supplying injection liquid to the injector chamber and through the nozzles (26) into the primary flow, and a downstream chamber where the main fluid flow is mixed with the fluid from the injector, and wherein that the downstream chamber is configured in such way that injected fluid from the one or more nozzle aperture or opening (26) to a large degree may be in the form of a directional determined flow, flowing out of the openings or aperture (26) along the circumference of the downstream chamber at least until the difference in energy of the injected flow is more or less levelled out with that of the main flow.
4. Ejector according to claim 3, wherein a number of fins or ribs (23) are arranged on the inner circumferential surface of the downstream chamber, extending downstream in generally longitudinal direction of the downstream chamber.
5. Ejector according to claim 4, wherein the ribs (23) extend upstream beyond the openings or apertures of the nozzle (26).
6. Ejector according to claim 5 wherein the ends of the ribs (23) extending upstream the openings or apertures of the nozzle (26) have a decreasing height in upstream direction .
7. Ejector according to one of the claims 3 to 6, wherein the upstream ends of the ribs (23) extend into interior of the ejector chamber.
8. Ejector according to 7, wherein the part of the ribs (23) arranged inside the ejector chamber and an outer and inner circumferential wall form guides towards the nozzle openings or apertures "6) for the supplied liquid to be injected.
9. Ejector according to one of the claims 4 to 8, wherein the upper surface of the downstream end of the ribs (23) are skewed downwards towards the ejector end, forming an angle a in the range of 2 to 10 degrees.
10. System according to one of the claims 1 to 9, wherein the liquid take out unit (40) comprises a duct or channel communicating seamless with the outlet of the first ejector (10) and the inlet of the second ejector (10') .
11. System according to claim 10, wherein the duct in the liquid taken out unit (40) comprises a number of parallel fins or plates (45) arranged in spaced relation and extending the direction of the general direction of flow, the ducts being in fluid communication with a surrounding annulus (44), the annulus (44) being in fluid communication with the inlet to the pump (31'), delivering liquid to the second ejector (10').
12. System according to claim 1 1 , wherein the fines (45) are configured to extend around the entire periphery of the a duct, and the distance between two adjacent fins (45) are chosen such that liquid is allowed to flow between the fins, while the particles transported I the main flow is prevented from entering the surrounding chamber.
13. Method for transporting goods from one station to another using a liquid as a transport agent, using an ejector as a driving means for creating a suction upstream of the ejector inlet, wherein an injected liquid flow is injected into a main flow carrying a goods, by forcing liquid through nozzle outlets or apertures, c h a r a c t e r i z e d in that the system uses more than one ejectors (10.10') arranged in series is used and where liquid to be delivered as injection liquid to a consecutive ejector (19') is drawn from liquid flow leaving an upstream ejector (10).
14. Method according to claim 13, wherein a liquid is withdrawn by means of a liquid take out unit by means of a pump delivering pressurized liquid to nozzles in the consecutive ejector.
15. Method according to claim 13 or 14, wherein the pump used for delivering injection liquid to the second ejector is the same as used for drawing liquid from the main flow in a suction unit.
16. Method according to one of the claims, wherein part of the liquid is drawn out of the main flow, while the goods still follow the general direction of flow .
17. Method according to claim 13, where the suction in the suction unit is created by a pump and that the same pump re-delivers the liquid to the downstream ejector as injection liquid.
