Preferably, the light source of the lighting device 400 irradiates toward the filter 220.
The method for purifying the hooked shrimps by adopting the hooked shrimps purifying device comprises the following steps of:
(1) Removing impurities: fine and large impurities are removed, the hooked shrimps are firstly loaded into a first bolting-silk net to wash out sediment, preferably, the first bolting-silk net in the embodiment is a 20-40-mesh bolting-silk net, the sediment is washed out by low-temperature seawater during washing, and then the washed hooked shrimps are put into the first bolting-silk net to screen out large impurities, preferably, the second bolting-silk net is a 2-4-mesh bolting-silk net. Removing the reason of tiny and massive impurities; firstly, tiny (such as sediment and the like) are too much to easily block the gills of the hooked shrimps, the breathing of the hooked shrimps is not facilitated, the anoxic death of the hooked shrimps is easily caused finally, and secondly, large-scale impurities (such as moss algae and the like) are too much to easily bring moss algae slices and spores thereof into a culture pond for stocking the hooked shrimps, so that the moss algae is flooded. Thirdly, too many tiny and large impurities are unfavorable for sales.
(2) And (3) dehydration: the dehydration is mainly because the water content of the hooked shrimps is too high, which is not beneficial to the dissolution of oxygen into water, and the hooked shrimps are easy to die due to lack of oxygen, and are put into a net bag smaller than the size of the hooked shrimps for spin-drying; specifically, the method can be used for manually drying the shrimps in the mesh bags with 20-40 meshes or putting the shrimps in the mesh bags with 20-40 meshes and using a washing machine drying barrel to dehydrate for 20-30 seconds, the dehydration time cannot be too short or too long, the shrimps are easy to die due to lack of oxygen caused by the fact that the shrimps are not completely dehydrated after too short dehydration time, and the shrimps are too dry and die due to too much dehydration time.
(3) Separating the hooked shrimps: the lighting device 400 is turned on, the hooked shrimps fall down from the hooked shrimp separating piece 200 along the filter screen 220 of the hooked shrimp separating piece 200, the lighting device 400 is used for irradiating the hooked shrimps from the bottom, the hooked shrimps are sensitive to strong light, the hooked shrimps can be drilled out from impurities after being irradiated by strong light, the separation of the hooked shrimps from the impurities and dead hooked shrimps is realized, the hooked shrimps can climb down along the inclined surface of the filter frame 210 after being drilled out from the impurities, the irradiation lasts for about 1 hour, more than 98% of the hooked shrimps can climb to the bottom position of the filter frame 210 of the hooked shrimp separating piece 200, then fall into the hooked shrimp receiving device 300, and the impurities and the dead hooked shrimps remain on the hooked shrimps separating piece, so that the purification of the hooked shrimps is completed. Proved by practical experiments, the purity of the hooked shrimps positioned on the hooked shrimp carrying device 300 can reach more than 99 percent, the purifying effect is good, and the operation mode is simple and convenient.
The invention utilizes the characteristic of strong light fearing of the hooked shrimps, so that the hooked shrimps can be rapidly separated from impurities, and the purification efficiency is high.
The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be apparent to one skilled in the art that modifications may be made to the technical solutions described in the foregoing embodiments, or equivalents may be substituted for some of the technical features thereof; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
