SU44179A1 - Floating device for transferring fish from the pool to the freezer - Google Patents

Description

It is known to use pumping units for reloading fish carried by a stream of water drawn from a fish storage and directed to a receiving tank. However, such fish suction installations are usually not sufficiently reliable in operation and consume a significant amount of energy from the transporting liquid, while the same (with the fish passing through the pump) are inapplicable because they violate the safety of the fish.

The proposed flotation device is intended to transfer fish from the pool to the freezer by means of a pumping installation, the essence of the invention is that between the suction pump and the fish collection pool there is a water-filled intermediate tank connected to the freezing hopper, into which the fish are dragged by the current pumped out water from it and from which it is then distilled into the receiving hopper of the freezer during the subsequent injection of water.

In FIG. 1 shows in perspective a diagram of the proposed device; FIG. A 2-pipe connecting the intermediate tank to the receiving hopper of the freezer is a longitudinal section; FIG. 3-tee connecting intermediate tanks with a pipeline through which fish and water are sucked out of the collecting basin - a longitudinal section; FIG. 4-connection of the suction pipe with a national pool, longitudinal section; FIG. 6- cross section through the freezer and drain tray; FIG. 1-grid of the freezer drain pan in the plan.

In the vessel's hold are two tanks 7 and 2, serving as intermediate tanks for fish to be reloaded. On the left, these tanks are connected by pipes 5 and - to the receiving hopper 6 of the freezer, between which funnel and the mouth of the mitrube 4 there is an inclined tray 5 with a mesh bottom, through which the transporting fish passes through and diverted to the side with a chute 7 and a tube 8. Ust pipes 3 - to . 4 are equipped with rotary valves 9 and W (FIG. 2). On the right, tanks 7 and 2 are connected by a tee 11 to pipe 74, to the end of which, a flexible hose / 6 connected in turn to a collecting tank with fish, for example, a pontoon 77, is connected to the end of the waterline passing through the vessel’s waterline. filled with water with fish and divided into parts by bulkheads. To receive fish from both sides, the pipeline H may be provided with a branch 75 directed toward the opposite side and also provided with a flexible hose connected to the pontoon with the fish. The pontoon 17 is provided with air drains to give it the necessary buoyancy when it is filled with water and is divided by a longitudinal bulkhead into two equal parts, which in turn can be divided by transverse lattice bulkheads into separate compartments to facilitate consideration of the fish being reloaded. In the fore part, the pontoon is equipped with a chamber Pa (Fig. 4), which is disengaged from the rest of the pontoon by placing a solid bulkhead and connecting it to the sleeve 16 through an opening blocked by a rotary valve 18. For communication with the outboard water, the pontoon is equipped with a lattice stern.

Tanks / and 2 through pipes 22 and 23 are connected to pumps (not shown in the drawing).

The pipeline 14 may be separated from the tanks / and 2 by means of the rotary valves 72 and 13 located in the tee 77 (Fig. 3). Directly above these valves into the tee are tubes and 20 and 2 /, which are connected. alternately to the tube 19, which with its other end enters the chamber 77a of the pontoon 77 above the valve 18. To transfer fish from the pontoon to one of the intermediate tanks 7 or 2, the system must be pre-filled with water. To do this, turn on the pump on the tube 75 (not shown in the drawing), through which water flows to the mouth of the sleeve 16, deflects the valve 18 and presses it to the saddle, fills the sleeve 16, pipe 7 and 75 and through the tee 11 enters the tanks 7 and 2.

The air displaced from the system will flow through tube 3 (or, respectively), deflecting valve 9 (or 10}, as well as through tube 24, through the side of the vessel and fitted with a non-return valve; since the bend of tube 24 is located below the bend of the tube 3, then the appearance of water from the tube 24 indicates that the entire system is filled with water.

After filling, in this way, the intermediate tank from it through the pipe 22 or 23, respectively, begins to pump iodine through a pump. With this, the flow

water will drain valve 18 and connect the receiving working chamber 77a with the rest of the system, and valve 9 (or 10 respectively) will press it to its seat and close the non-return valve in tube 24, as a result of which water will flow with fish into reservoir 7 ( or 2).

When the intermediate tank is filled with fish, the pumping of water from it stops and water is pumped into it through pipe 20 (or 27). The flow of water will deflect the valve 72 (or 75) and press it to its saddle, separating the intermediate tank with the fish chamber. Pumped water will fill pipe 4 (or 5), deflect valve 9 (or 7 (9) and will pour into tray 5, through which fish entrained with water will slide into the freezer receiving hopper 6, and the water passing through the grate bottom of the tray will fall into the trough 7 and will be withdrawn from it by tube 8.

During water injection into the tank 7, it is possible to pump water out of the tank 2, filling it with fish from the pontoon. A series of work of both tanks, it is possible to achieve a continuous supply of fish from the pontoon to the receiving funnel. By pumping water into both intermediate tanks, one can simultaneously feed the fish into the receiving hopper of the freezer, and by simultaneously pumping out the water, both tanks can be loaded with fish from the pontoons 17. The pontoons are loaded with fish from boats. After at least one half of the pontoon is loaded with fish, all transverse bulkheads in this half are removed and the fish are drawn into the intermediate tank.

The freezer chamber is made in the form of a horizontally curved pipe 25 with vertically-curved ends located in the middle of the chamber, one of which communicates with the funnel 6, and the box 26 (Fig. 6) adjoins the other end, equipped with an inclined tray 27 with a grate bottom made of two grids: 25, used for draining the freezing liquid displaced from the freezer chamber, and 57 for draining water, washing the frozen fish, slipping along tray 27 (Fig. 7). Under the grill 28 there is a chute 29, through which the freezing liquid passing through the grill is led to tank 30 (phage 1), and under the grill 5 / there is a chute 32, through which the water is flushed out overboard.

The tube box of the freezer is provided with a longitudinal slit 37 (Fig. 5) communicating with the internal cavity of the chamber

the sheet 3, which is bent out from the outside and riveted to the chamber wall, forms, together with the inner sheet, an additional cavity into which the amoraging fluid is pumped through the pipes 34 and pours into the freezer chamber through the slit 37.

From the bottom of the freezer compartment, along its length, are attached a row of tubes 35, fitted with valves and included in a common collector 36, from which the spent freezing fluid is directed to the tank 30.

Fresh freezing fluid is supplied to the freezer compartment through pipes 34 in larger amounts than it flows through tubes 35 to collector 36, as a result, excess freezing fluid is poured together with frozen fish into box 26, and from it is drained through tray 27, and freezing fluid, having passed through the grill 28, it is directed along the chute 2P into the tank 30, and the fish, sliding off the web, is washed with clean water, discharging through the grill 5 / and discharged through the chute 32 overboard, and enters the container 38.

Due to the fact that the density of the freezing liquid is usually greater than one, the fish, trying to float in it, could freeze to the walls of the freezing chamber. However, when floating, the fish will fall into a stream of freezing fluid flowing under a known pressure from the slot 37 tangentially to the circumference of the chamber cross section, as a result of which the fish, along with the freezing fluid, will rotate around the longitudinal axis of the chamber and sink down. After the supply of manpower supplied to the fish by the stream of the freezing liquid is exhausted, the fish will re-emerge, but, falling under the stream of liquid escaping from the slot, will again sink and thus will not be able to press and freeze to the chamber walls. will participate in the forward movement of the fluid created by the difference in the supply and selection of the latter. Using the valves to change the amount of liquid taken, it is possible to regzlirovat the rate of passage of fish through the freezer.

The subject matter of the invention.
