Description

Technical Field

[0001] The invention relates to an Antarctic krill ship end shrimp water separation and conveying device, belonging to the technical field of fishery machinery. Background Art

[0002] All fishing activities in the Antarctic waters are strictly managed by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). CCAMLR implements a quota-based fishing management system for Antarctic krill fisheries. Krill fishing is an internationally competitive situation, that is, the total catch is certain, and the greater the fishing capacity of the fishing vessel, the greater the competitive advantage. In recent years, the main krill vessels engaged in the Antarctic krill fishery are Norway, South Korea, China, Ukraine, Chile and other countries. At present, Norway has 3 continuous pump-suction professional krill fishing and processing vessels, China has 1 independently developed continuous pump-suction professional fishing and processing vessel, and the rest are traditional tail slide trawlers. The annual output of continuous pump-suction krill vessels accounts for more than half of the total krill output. Developed fishery countries represented by Norway have built the Antarctic krill fishery into a new marine biological industry supported by efficient fishing technology, driven by high value-added products, and integrating fishing and shipboard processing. It presents a new form with high technical barriers, long industrial chains, and greatly improved economic benefits, which fully demonstrates the huge productivity of innovative technologies. Therefore, the higher the degree of automation in Antarctic krill fishing and processing, the greater the share of Antarctic krill fishing will account for, and the production space for traditional fishing vessels will become smaller and smaller. The level of automation in Antarctic krill fishing and processing has a great impact on the production capacity and quality of krill products.

[0003] The existing Antarctic krill processing ships generally use an inclined upward screw conveyor for conveying and separating krill from water. During the screw conveying process, the krill bodies are seriously damaged due to the sliding and rolling of the krill. Summary of the invention

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Antarctic krill are continuously pumped and caught, and their flow rate is often much greater than the processing capacity. Therefore, they need to be pumped into the cold seawater tank 4 for temporary storage. During this period, the Antarctic krill are squeezed through the net bag and then transported over long distances through the pumping device. Some shrimps are already fragile in their biological state. The shrimps are taken from the cold seawater tank through the energy-saving and low-loss shrimp water separation and transportation device on the Antarctic krill ship end. The Antarctic krill shrimp water separation and transportation device is matched according to the calculation of the ship end processing capacity. After the shrimp and water mixture is separated, the Antarctic krill is directly lifted and transferred to the conveyor belt for transportation to the processing workshop.

[0026] The technical solution described in this embodiment can solve the problems of the hopper conveying capacity, low-loss transportation technology, drainage hole area, and scattered shrimps in the Antarctic krill ship-side energy-saving and low-loss shrimp water separation device. The specific description is as follows:

[0027] See also Figure 1-Figure 5 , a shrimp-water separation and conveying device at the end of an Antarctic krill ship, comprising a hoist 6, a shrimp suction pump, a shrimp-water mixture input pipe 5, and a conveyor belt 7; the hoist 6 has a first horizontal section, a hoist section, and a second horizontal section in sequence, and a hoist inlet 11 is provided at the upper part of the first horizontal section, and the hoist inlet 11 is connected to the bottom outlet of the cold sea water tank; the hoist 6 has a guide wheel 9 and a guide chain inside, and a plurality of hoppers 8 are hung at intervals along the guide chain, and the hoppers have water-leaking punching holes; a hoist outlet 13 is provided at the bottom of the end of the second horizontal section, and the conveyor belt 7 is provided below the hoist outlet 13; a hoist return water port 12 is also provided at the lower part of the first horizontal section, and the hoist return water port 12 is connected to the cold sea water tank through a return water pipe 2 and the shrimp suction pump provided thereon; the shrimp-water mixture input pipe 5 extends below the liquid level of the cold sea water tank.

[0028] In this embodiment, see Figure 4 and Figure 5 A flexible baffle plate 10 is installed below the entrance of the elevator. There is a set small gap between the lower surface of the flexible baffle plate 10 and the hopper 8 at the corresponding position to prevent the shrimp-water mixture from falling out of the hopper following the turbulence generated by the water flow when it enters the hopper 8.

[0029] In this embodiment, see Figure 4 and Figure 5 The hopper 8 is rotatably connected to the guide chain so that the open end of the hopper always faces the forward direction during the movement.

[0030] In this embodiment, see Figure 4 and Figure 5 , the hopper 3 is in a trapezoidal shape.

[0031] See also Figure 2 and Figure 3 The outer shape of the elevator 6 is Z-shaped.

[0032] See also Figure 4 and Figure 5 The flexible material blocking plate 10 covers the periphery of the elevator entrance 11 and a distance in the forward direction of the hopper.

[0033] See also Figure 4 and Figure 5 The punching holes are provided on the side and bottom of the hopper.

[0034] The working method of the above-mentioned Antarctic krill ship-end shrimp water separation and transportation device is as follows:

[0035] After being processed by the pump-suction fishing equipment, the shrimp-water mixture enters the liquid surface of the cold sea water tank 4 from the shrimp-water mixture input pipe 5, and the proportion and temperature of the shrimp-water mixture in the cold sea water tank 4 are adjusted; the shrimp-water mixture is extracted from the bottom of the cold sea water tank 4 and the connecting port of the elevator inlet 11 and the elevator return port 12 by using the centrifugal shrimp suction pump 1, the return pipe 2 and the elevator 6. The shrimp-water mixture moves from the elevator inlet 11 to the elevator return port 12 with the water flow, and the water flows out from the punching hole of the hopper 8, and the shrimp remains in the hopper 8. A flexible baffle plate 10 is installed below 11 to prevent the shrimp-water mixture from entering the hopper 8 and scattering out of the hopper 8 along with the turbulence generated by the water flow. It moves horizontally for a distance and then stabilizes before being lifted. During the lifting process, after the shrimp and water in the hopper 8 are separated, the guide wheel 9 makes a vertical movement and lifts it to the top of the conveyor belt 7, and the hopper 8 is turned over to pour out the Antarctic krill. The Antarctic krill falls onto the conveyor belt 7 through the elevator outlet 13 and is transported to the processing workshop. A small amount of shrimp scattered in the elevator 6 is pumped back to the cold sea water tank 4 along with the circulating water using the centrifugal shrimp suction pump 1.

[0036] The device can uniformly and continuously transfer and separate the shrimp-water mixture, and will not cause large-scale accumulation of Antarctic krill, which will lead to damage to the Antarctic krill body and deterioration in quality, thereby ensuring the needs of high-value deep processing. Specifically, it has the following advantages: after matching the flow rate with the continuous pump suction fishing device, the shrimp-water mixture is continuously separated, and the hopper drives the shrimp to move to avoid damage to the shrimp body caused by spiral conveying in the prior art. The hopper body is punched with holes to separate the shrimp and water while transporting the Antarctic krill to the conveyor belt mechanism without loss; it involves the transfer, lifting, water separation and cold seawater circulation of the shrimp-water mixture, which improves the automation level of shrimp-water separation, and the circulating water system is green and energy-saving. The shrimp taking and shrimp-water separation parameters are designed and matched according to the processing capacity, thereby realizing the automation of the shrimp-water separation link in the Antarctic krill fishery; an outlet is opened at the bottom of the elevator to recover cold seawater and scattered Antarctic krill, which are recovered to the cold seawater tank by a return pipe and a shrimp suction pump to form a closed circulation loop.

[0037] The above are preferred embodiments of the present invention. Those skilled in the art may also make respective changes or improvements thereon. Without departing from the general concept of the present invention, these changes or improvements shall fall within the scope of protection claimed by the present invention.
