SU1253959A1 - Device for filling container with fluid - Google Patents

Description

The invention relates to a dosing technique and can be used, for example, in the chemical industry for filling containers with corrosive liquids.

The purpose of the invention is to increase reliability and simplify the design.

FIG. 1 shows the proposed device, a general view; in fig. 2 - the same, the final position; in fig. 3 shows the node I in FIG. one; in fig. 4 shows section A-A in FIG. 2

The device consists of a supply tank 1, a nozzle 2 installed therein for supplying liquid, a level regulator 3, a support pipe 4 with an emphasis 5, a drain pipe 6 coaxially disposed therein with an electrically conductive rod 7 located therein with a cable 8 for removing static electricity, mounted with the possibility of vertical reciprocating movement of the measuring cup 9, the locking device 10 and the lever system 11 containing the lead 12, the slave 13 and the intermediate 14 levers, while the lead 12 the lever ujap- Nirn is mounted with the middle part on the support 15, one of its shoulders 16 is connected by means of pins 17 to the drain pipe 6, and the other shoulder 18 to the intermediate 14 lever. On the discharge pipe 6, it is reinforced with a flexible pipe-source of vacuum and has 21 and a sealant cartridge 19, a wire with a second spool 22.

Valve from the housing 23

system 10 may be centered

a spring-loaded threaded rod 24, one end of which is connected to cable 8 for discharging static electricity, and on the other a plate 25 is fastened with a gasket 26, while the electrically conductive sterr, gum 7 is connected to the plate 25.

The device works as follows.

The filling fluid enters the supply tank 1 through the nozzle 2, and its level is maintained by the level 3 regulator.

In the initial position, the measuring cup 9 is located in the liquid below its level in the reservoir 1, and the cartridge 19 with the drain pipe 6 is in its extremely low position and connected to a vacuum system. The spool 21 under the action of the spring overlaps the message of the internal cavity of the cartridge 19 with a vacuum system.

The lifting table 27 with the container installed on it, after the corresponding command, lifts it to the specified working height. In the process of lifting the container rests on the cartridge 19 and lifts it. The seal 22 seals its neck, compresses the spring 28, and the spool 21 approaches the stop 5 of the support pipe 4. Under the action of the stop 5, the spring is compressed until the spool 21 reaches the lowest position, which allows the drain path to reach the vacuum. -system

Simultaneously with the cartridge 19, the drain pipe 6 rises, and the measuring cup 9 rises above the level of the liquid, the compartment in this way, the desired dose.

When lifting the drain pipe 6, the shoulder 16 of the driving lever 12 rises up, and its second shoulder 18 is lowered down through the intermediate lever 14. carries along the shoulder 29 of the driven lever 13, as well as the locking device 10 interconnected with it. locking device 10 lowers down the conductive rod 7 to the bottom of the container. The rod 7, having reached the bottom, rests on nei o, and the locking device 10, continuing to fall under the action of the lever system 11, compresses its spring 30, thus compensating for the inaccuracy of the container in height and reliable sealing of the vertical end of the drain pipe 6.

Thus, at the maximum lift of the drain pipe 6 upwards, the locking device 10 descends to the maximum. After the upper end of the discharge pipe 6 is sealed by a vacuum, the liquid is drained into the container. After emptying the measuring cup 9. Since it is placed above the liquid, air enters the discharge pipe 31, the vacuum in the system drops and the table lowering drive is automatically activated, and the drain pipe 6 is lowered by spring action. One drain pipe (tr) - the conduit 6 is carried down by the shoulder 16 of the driving lever 2, and the shoulder 29 of the driven lever 13 rises upward under the action of the intermediate lever 14 and the lever system 11 occupies the initial position.

When lowering the drain pipe 6, the spool 21 moves away from the stop 5 of the support pipe 4 and under the action of the spring disconnects the device from the vacuum system. On this cycle of the device is over.
