Description

The device consists of a measuring device for bulk solids, a measuring device for liquid bodies, a distributor for matching the supply of bulk and liquid parts of the mixture and a stirrer for mixing the mixture. The bulk solids gauge is a rotary drum placed in a closed casing and provided with a certain volume of compartments that receive the bulk body from one side of the casing and transfer it from the other side to the mixer. The liquid dipstick is a closed tank that carries a plunger on its lid and overlaps the end of a vertical pipe, which in turn serves as a supply and drain pipe. The distributor for simultaneous rotation of the measuring device of bulk solids and the three-way valve on the pipe of the measuring device for liquid bodies is a shaft carrying on itself two teeth, one of which is connected to the shaft of the drum, and the other to the tail of the valve of the three-way crane. The agitator is designed in the form of a removable vessel, equipped with a fixed gear and blades, which are fixed on two gears, enclosing the fixed gear.

In the schematic drawing of FIG. 1 shows a general view of the device with partial cuts; FIG. 2 - section

duplicated three-way crane; FIG. 3 and 4 - two cuts of the bourgeois.

Inside a fixedly reinforced casing 3 (Fig. 1) communicating through the adjusting valve 2 with the lower conical part of the loading tank 1 fixedly mounted on the racks supporting the device, there is a rotary drum 4 for measuring the bulk material, equipped with blades that divide the annular space between with a drum and a comb into six defined volume of compartments 5, which, when the drum rotates, receive bulk material from the tank 1 and transfer the sleeve b to the metal box 7 of the agitator.

In the guide slots 9 and 10, mounted on the same racks of the device, a reservoir 8 for measuring the liquid is freely located, equipped with a bottom, which through the gland 11 freely surrounds the pipe 12 connected to the feed pipe 14 and the outlet pipe 15 to the agitator box 7 through a duplicate three-way valve 13 (Fig. 2). The lid of the tank 8 is provided with a cable; the valve 18 of which, when the tank is filled with liquid from the pipe 14 through a three-way valve and the pipe 12, floats up and, closing the opening 19, informing the inner space of the tank with the outer

air, stops the flow of fluid into the tank. When liquid flows out of the tank through the upper opening of the pipe 12 and further through the duplicated three-way valve, through the pipe 15 into the mixer box 7, the same drill is lowered and again communicates the inside space of the tank with outside air. The volume of fluid transferred through the tank for each flow depends on the height of the cover over the pipe 12, what height is adjusted by means of gear 17 coupled with a rail mounted on the outer wall of the tank, and the volume is determined on a scale of 16, an indicator strengthened on the wall of the tank.

In order to match the flow of the bulk and liquid parts into the mixer, the shaft of the drum 4 and the tail of the tap of the crane 13 are connected via chains of Gall 21 to the shaft of the distributor, which carries on itself a handle 20 and two teeth, ONE for each chain, with such gear ratios, that when the handle is turned half a turn, the drum is turned one twelfth and the crane is turned one quarter turn.

In order to mix the bulk and liquid parts of the mixture, the device is equipped with an agitator, the removable metal box of which (Fig. 3 and 4) is pressed by means of a spring abutting against the turning support 26 against the rigid support 24 fixedly mounted on the racks of the device. Gear 27 is rigidly attached to the center of the box, in its center, and the gear from the handle 25 or from the drive pulley through a pair of bevel gears 23 to the shaft 28 is located above the same pinnacle; freely passed inside the box through the support 24 and gear 27 and carrying the bar 29 rigidly fastened on it at its end inside the box. Through the ends of the bar 29, rollers 30 freely coupled to gear 27 by means of gears 31 and fitted with vanes 32 are missed. When the shaft 28 rotates

The rollers 30, rotating around their axis, simultaneously move around the axis of the shaft 28, as shown in the drawing (Fig. 4) by arrows, mixing the material filling the agitator.

At the position of the drum indicated in the drawing (Fig. 1), when the bulk material is fed from it through the sleeve 6 into the mixer box 7, the tap of the valve 13 is in the position telling the tank 8 with the same mixer box. When the distributor knob is rotated half a turn, the valve plug informs the tank 8 with the supply pipe, when the distributor knob is turned to the next half turn-tank with liquid and the next drum compartment is again connected, the mixer is empty and emptied, and the opposite drum compartment is charged from the tank, 1 new portion of bulk material.

The subject matter of the invention.
