SU31639A1 - Automatic scales for fluid bodies - Google Patents

Description

In the proposed automatic scales for liquid bodies, the latter enter one of two drums, equipped with drain holes and swivel under, hung on earrings to the arm of the rocker, with an eccentric arrangement of one relative to the other. By means of the pin drums fixed on the bottom and the rod resting on them, the inlet valve is kept in the open position until the balance is reached when equilibrium occurs, after which the fluid is added to a certain weight from an additional tank.

The drawing shows a front view of an automatic balance for liquid bodies.

The weighed liquid enters the acceptance collector /, from where through the discharge pipe 2 enters one of the two swing-arms of the rocker J3 of the rocker arm J3 a and b, which are inserted one into the other, with common bottoms and with diametrically located drain holes: for inlet and draining the liquid from both compartments thus obtained. The drums a VI b are eccentrically positioned relative to each other, with the eccentre | 1 system e and the angle a of inclination of the line connecting the centers of the two cylinders to the horizontal axis of the large cylinder so that the drum with one half filled

its capacity, due to the displacement of its center of gravity from the axis of the support, had such a reserve of potential energy that, if it went over during the tilting of the drum to the kinetic, it would be able to perform the following work: turn the drums 180 °, raise the gate 7 to the position shown in the drawing, and lift the rod 8 together with the valve 9. The excess force is spent on hitting the buffer U in the rubber pad of the buffer //.

The drums are hung on two earrings 12 to the shoulder 3 of a double equal-arm rocker arm 13, at the other end of which a cup 14 for weights is suspended. The opening of the discharge pipe 2 of the collector /, closed by the valve 9, must be larger than the opening of the pipe supplying the liquid to the collection / so that the incoming liquid does not remain in the collection when the valve 9 is opened. Collection 1 serves to collect liquid in it only during topping up the weight and rollover drums. The pipe 2 is connected by a wide pipe 26, equipped with a tray. 75, with a canister 16 serving to trap a portion of the liquid, the bottom of which is connected by a narrower tube 27 to a tube 2.

When the balance is in position shown in the drawing, the collection / liquid enters the pipe 2 into the bar an b, the second drum a is empty. As the drum b is filled with liquid, the arm 5 is lowered, at which time the buffer 10 moves down and is released from the buffer 11 holding it, the drum rotates slightly and the protrusion 5, located rik the common bottom of the drums, presses against the hook 6, which keeps the drum from rotating and tipping to the side indicated by the arrow. In this chewing roller roller 8 departs from the pin 28 supporting it, fixed on the bottom. At this time, the balance is still in the equilibrium position, since the part of the weight of the valve 9 and the rod 8 that was earlier acting on the drum ceased to be transferred to it. In order to reach the maximum weight, the liquid continues to flow in a thin thin stream from the tank 16. As soon as the full weight is reached and the balance is in the equilibrium position, the arrow of the balance 17 will touch the spring plate 18 and close the electromagnet, thus causing the 7P electromagnet to move the latch 20 back. the lump-like gate 7 falls down and covers the opening of the pipe 2, catching a jet of liquid at the moment of turning the drum. The crank lever 21, which is on the same axis with the gate 7, lifts the hook 6 with the help of the rod 22 rotating on the stud 12 and releases the protrusion 5, and the drum, tilting, turns around its OSIN half a turn. Due to pouring a part of the liquid out of the drum b through the hole rf, the shoulder of the rocker arm 75 rises and the drum takes up its original position in height. The second buffer 10 engages the protrusion 23 of the gate 7 and lifts it into its original position, hits the rubber pad of the buffer //. The second pin 28 fits under the roller of the rod 8 and lifts the valve 9, due to which the liquid from the collector 7 begins to flow through pipe 2 into the drum and through the opposite

pipe 2 hole with. From the filled drum b, however, the liquid is poured out through the opening d turned down. Further, the effect of the scales is repeated. The turns of the drums are fixed by a rev counter 24 attached to the shackle 12. The movable weight 4 serves to adjust the time of the fluid valley to a certain weight ..

The subject matter of the invention.
