SU961631A1 - Apparatus for sorting fish spawn - Google Patents

Description

The invention relates to the processing of fish, in particular, to devices for the purification of impurities of fish roe, mainly mints, and can be used at coastal enterprises and at sea level fish.

A device for sorting fish eggs is known, which is a table that has screens on both sides, illuminated by whitewaters, as well as pockets for collecting impurities. Workers serve caviar on the surface of the screen and choose impurities with tweezers in their pockets. The caviar is sorted in such a way on the bent side of the screen is discharged into special containers.

The known device is poorly produced. requires manual labor.

The closest to the proposed technical, essence and achievable effect is a device for sorting caviar, including a caviar silo feeder, a device for feeding caviar for sorting, an illuminator, a photosensor associated with the last actuator

for dropping caviar and collections of clean caviar and waste C2J |.

In the known device, the device for feeding the caviar to the sorting consists of a screw mounted in the bunker and driven into rotation of the table with the groove along the edge to create a stream of caviar in the form of a chain. The speed of rotation of the table and, consequently, the supply of caviar is limited by the centrifugal force that drops eggs from the table, which limits the performance of the device. In addition to this, the presence of a screw and a table driven in rotation makes the device more complicated.

The purpose of the invention is to simplify the design and improve the performance of the device.

30 is a pumping hopper and a nozzle mounted on its discharge pipe, with the pump and nozzle arranged vertically to direct the calf to the collection of clean caviar. The drawing schematically shows the proposed device. The device consists of a bunure treatment unit 1 of caviar, a pump 2 located under it, a nozzle 3 installed on a pohpednee discharge pipe, an illuminator 4, an actuator 5 for dropping rejected caviar, a tray 6, a collection of 7 pure eggs, a collection of 8 waste, and also between the photo sensor 9 of the reference one, the photo sensor 10 of the control sensor, the amplifier 11 of the electric signal, the generator 12 of the electric pulse, the amplifier 13 of the electric pulse and the electric drive 14 of the executive mechanism 5 (electric magnetic, piezoelectric or electrodynamic). The device works as follows. By pump 2, the semi-finished product caviar from the feeder bin 1 through the nozzle 3 is jetted 15 through the open space into the collection 7 of clean caviar. At the source, the stream of semi-finished caviar shines through the illuminator 4 and controls the photo sensor 10 for lumen, producing an electrical signal together with the reference photo sensor 9 when an impurity particle passes through the stream that differs from pure caviar in color. an electrical pulse, which is amplified in the amplifier 13 and fed to the actuator electric drive. 5. The impurity particles detected by the photosensor and moved with the jet during the response time of the actuator from the photosensor under the actuator blade 5, together with the jet section 16 containing these particles, are intercepted by the actuator and are sent to tray 8 for waste. The proposed device, in which the supply of caviar with a stream for sorting and separation is provided, ensures the achievement of high productivity, is easy to maintain, and using it will eliminate the dissemination of eggs by microorganisms in the process of its separation. The economic effect from the introduction of the device on the vessels of the Far Eastern Basin will be more than 1.5 million rubles. The invention includes a device for sorting fish eggs, preferably mines, including a caviar feeder, a device for feeding eggs for sorting, an illuminator, a photo sensor, the last actuator for discarding rejected caviar, and collections of clean caviar and waste, characterized in that , in order to simplify the design and increase productivity, the device for feeding caviar to sorting consists of a pump located under the feed hopper and installed on its discharge nozzle cost sharing, the pump and the nozzle are arranged vertically to direct a stream of eggs in the collection net calves.
