(54) DEVICE FOR REMOVAL OF IMPURITIES FROM FISH RAW

I

The invention relates to separated solid materials by means of a liquid, namely, devices for removing impurities from fish raw materials, and can be used on vessels and enterprises of the fishing industry.

A device is known for removing impurities from: fish raw materials, containing a feed bin, a chamber, one of the side walls of which is inclined, a water separator connected to the chamber, made in the form of an inclined perforated tray, devices for pumping water into the chamber, one of which located under the bunker at the level of the transition of the inclined chamber wall into the water separator, and a device for collecting and unloading impurities 1.

However, the known device does not have high performance, does not ensure complete removal of impurities from fish raw materials and requires a lot of water pressure.

The aim of the invention is to provide more complete removal of mechanical impurities from fish raw materials and increase

device performance with a simultaneous decrease in water pressure.

The goal is achieved by the fact that in the device, including the hopper, the chamber, one of the side walls of which is located obliquely, the separator connected to the chamber, made in the form of an inclined perforated tray, devices for pumping water into the chamber, one of which is located under the transition level of the inclined chamber wall into the water separator, and the device for collecting and unloading impurities is mounted in the bottom of the chamber, the inclined wall of the chamber is concave, and the bottom is opposite to ENKA - vyfj convex, installed inside the chamber rotatably driven blade of an elastic material and the partition forming the wall of the inclined concave sections alternating gap whose width increases toward Jizni part of the chamber, wherein

ao is the second water injection device; it is located in the gap at the junction point; the concave wall of the concave wall is in the device for collecting and unloading impurities, and the water injection device is made with a series of nozzles.

FIG. I schematically depicts the proposed device; in fig. 2 — water injection device.

A device for removing impurities from fish raw materials contains a feed hopper 1 and a chamber 2 for separating mechanical impurities.

The side wall 3 of chamber 2 is inclined and concave, and the bottom and opposite wall are convex. With chamber 2 a water trap 4 is coupled, made in the form of a well-aged inclined perforated tray. for injecting water into chamber 2 and a device for collecting and unloading impurities, mounted into the bottom of chamber 2, which is a collection 6 with an opening bottom 7.

Inside the chamber 2, there are mounted rotatable blades 8 of elastic material and a partition 9 forming an alternating section gap with an inclined concave wall 3, the width of which increases towards the lower part of chamber 2. In the upper part of the gap between the partition 9 and wall 3 there is a slot 10, and In the lower wide part of the gap at the point of transition of the inclined concave wall 3 into the collection of 6 mechanical impurities is located the second device 1 for pumping water. Devices 5 and I for injecting water are made with a series of nozzle openings 12.

A device for removing impurities from fish raw materials works as follows.

The raw materials coming from the hopper 1 into chamber 2 are mixed with water coming from the nozzle holes 12. In the chamber 2, a circular directional flow of water is provided by chamber 5 and I for pumping water, and a number of nozzle holes 12 provide high speed This layer is across the entire width of the chamber 2. The arrangement of the water injection device 11 in the wide part of the gap ensures its ejection through the slot 10 of the chamber 2. Narrow strong jets of water push the raw material, and mechanical impurities, settling to the bottom, enter the collection 6, from which through the opening bottom 7 are removed. Fish raw material is picked up by a directional circular flow of water and carried to the surface to the water trap 4. Elastic vanes 8, rotating at a speed of 30-40 rpm, promote the fish raw material from the chamber 2 to the water separator 4 In the water separator 4, the water separates completely from the water.

The proposed device allows reducing the water pressure and eliminating multiple

closed circular movements of fish raw materials in the installation chamber, thereby increasing the productivity of the device.
