(5) PORTABLE METAL BATTERY DISPENSER

one

The invention relates to metallurgy, in particular to the protection of compact pallets from premature heat when casting steel from the top into through molds.

Until recently, protection of pallets from premature heat and the prevention of ingots ingots to them when casting steel from above was carried out by stacking in the cumpel pits of the pallets of specially shaped inserts concave in the shape of a cumpel. Protecting the pallet from the heat and welding of the ingot, the liner also reduces the surface defect of the ingot - to the captivity, as it creates a cushion of liquid metal, which reduces splashing on the walls of the burner.

Recently, in order to save quality metal on liners and refusal to manufacture and lay down, they began to use a backfill of a dimple recess in their place. In the pallet, sheet rolling wastes - sheet shear,

It is very important when dumping trim on the pallet is its dosing, respecting the optimal amount for a given weight of the type. An insufficient amount of trimming does not give the expected effect; an excessive amount leads to an increase in the bottom trimming during rolling.

The closest in technical essence is a device for loading the charge into an electric furnace containing a hopper with vertical walls, a crane hook and a sector lock with

IS doors P 1.

A disadvantage of the known device is that it does not have the ability to produce a material.

20 in several portions, does not allow the material to be concentrated in the center of the pallet, and also significantly increases the debt of crane operations.

when servicing multiple pallets.

The purpose of the invention is to improve metering accuracy and increase productivity.

This goal is achieved by the fact that the metering device containing a sector-locked bunker with flaps and a crane hook is additionally provided with a counterweight, made in the form of a base plate with a window and levers, kinematically connecting the base plate with sector-gate leaves, and adjustments are made in the levers holes.

The length of the levers selected and fixed by the fingers in the hinged joints ensures the dispensing of a strictly defined dose dispenser when lowering it on each pallet.

FIG. V shows the batch dispenser in the initial position; Fig.2vid bottom of the dispenser at the time of the dose; in fig. 3 dispenser at the time of its transfer by crane from one pallet to another.

The batch dispenser includes a hopper 1 with vertical walls and an outlet 2, a receiving funnel 3, a crane hook with support 5 for orienting the dispenser and a sector closure 6. To the sector closure on the levers 7 through the hinges 8 there is a cracked support plate - counter load 9 having a window in the center 10. The levers are equipped with adjustment adjusters, 11. The dispenser is filled with trimming 12, located under the tray 13 with a cumpell, recess 1L.

The portion dispenser operates in the following manner. one

The dispenser is installed on the floor of the workshop and the silo 1 through the receiving hopper 3 is filled with trimming 12. Then a crane, for the crane hook k, is passed over the composition of carts with pallets 13, previously blown with compressed air. The dosing unit is oriented on the crane suspension in one position with the aid of a stop 5

The crane driver, visually centering the base plate 9 in the center of the dummy tray 13, lowers the dispenser on each of the pallets. At the same time, the support plate, after contact with the pallet, presses the levers 7 which, turning in the hinges 8, forcefully open the flaps sec.

the rotary shutter under the force of the body of the tin of the hopper with trimming. When the shutter is fully opened, the trimming 12 is lowered along the mine hopper 1, the exhaust hole 2 passes, and through the window 10 in the base plate enters the plug recess AND of the pallet. Upon reaching the bottom of the dimple recess, the trimming column stops, but does not spread, since its height does not exceed 1.8-2.0 of the length of the trimming strip. After that, the dispenser is raised.

When lifting, the massive support plate at the first moment remains on the pallet and turns the flaps of the sector plate towards the closing side by the levers. The shutter flaps do not intersect the immobilized trimming column, turning at a slight angle, securely clamp

it from the sides under the action of the force of the sheet support plate - a counter-load with levers.

Upon further raising of the metering unit, the plate is detached from the pallet, and at the same time the stobl trims into a dose left in the capsule well and the rest of the trimmings in the metering unit.

The counter-load is chosen such that a partial cover of the shutter with the trimmed clamped on it is sufficient to reliably hold the remaining trim column in the bunker. In this position, the dispenser is transferred to the next pallet and the operation is repeated.

Changing the dose of trimming is achieved by jokingly changing the length of the levers 7 by swiping the fingers in the hinged joints through the holes 11. Extending or shortening the levers results in a corresponding dose change, as it changes the height of the trim column to the outlet of the hopper with the feeder lowered within 1 , 8-2.0 length trimming
