SU59012A1 - A device for spilling liquids - Google Patents

Description

The proposed device for spilling liquids, mainly for bacteriological nutrient media, refers to the type of devices in which the spill is effected by the force of compressed air, using a reservoir for the liquid to be dispensed, communicated through a distribution valve with a measuring vessel, forcing air fluid. According to the invention, this device is provided with a distribution device consisting of two spring-loaded clips operating from a pedal, acting on a system of tubes, supplying liquid and compressed air from a reservoir and a measuring device pumping air, and diverting them from the measuring device to a receiver and in atmosphere . The invention also provides for the use of a spare magazine for compressed air, which is injected with fur through a pipe with a baffle valve. By using this device, the proposal has in mind: 1) to facilitate the work of maintenance personnel in relation to pumping air and simplifying manipulation during the production of a spill compared with existing devices, 2) speeding up and refining the pouring of the medium on mattresses and 3) reducing the cost of manufacturing by simplifying the design and easy replacement of worn parts.

The drawing shows a schematic general view of the device.

On table 5, the legs of which are attached to the floor 44 by means of squares and screws, is placed a tank 1 for molten agar medium with a rubber stopper 4 held by the lever bolt 4. A glass tube slider 6 passes through the stopper and is connected to clamps with flexible hoses for inlet and outlet compressed air from a spare magazine in the form of a battery of bottles 35, into which it is pumped with the help of fur 26. In the bottom board of the fur, there is an intake valve 33 and a pipeline is fastened, which supplies compressed air through the baffles valve 34 in the bottle. The upper fur board is equipped with an edge 28 with a shackle 29 in which the lever 30 slides. The fur with its lower board and the end of the lever 30 are mounted on a separate board reinforced to the floor 44 and the leg

- desk screws. To lift the lever 30 upward, there are rubber rods 32. The side tube 2 of the tank 1 is designed to connect a short flexible tube with a clip connected to an agar spill tool. The latter consists of a graduated grader 14, connected to the bottom with agar pipes, and at the top through a ball fuse 15 (to prevent possible transfer of agar to the air ducts) with air pipes from which the outlet opens freely to the outside. A measuring device designed to fill two mattresses — a small size of 100 m of medium and a large (normal) size of 133 m of medium — can be provided with a casing to prevent the agar solution from solidifying. All four tubes 16a, 166, 8a, 86 (supply and output air, supply and output agar) are blocked by spring-loaded clamps 12, 12a, which are controlled from pedal 38 using wire grids 42. When the pedal 38 is in neutral position, all tubes are overlapped. When the pedal is pressed with the toe, the clip 12 opens, blocking the output of the compressed air from the measuring device 14 to the tube 166 and the tube For feeding the agar into the measuring device; when you press . pedal opens the clip 12a with a pedal, overlapping the tube 1ba, supplying compressed air to the measuring device, and the pipe 86, removing the solution of agar from it, which through the cannula 17 is poured into the mattress 18 being inserted underneath it An agar tank is connected to the tank 1, which is also a safety valve, for which the long bend 21 of the manometric tube 20 has an expansion at the top filled with mercury when an excessive pressure is formed in the pipeline. In this way, the air leak can come out through the expansion tube, the end of which is lowered into the cup 22 in order to avoid loss of mercury, which can be carried along by the air passing through. Lynometer mounted on board 19, reinforced

on table 5, and facing the person working on the device.

The order of operation using the proposed device is as follows. Before starting, pour the agar solution into the pre-heated tank 1 with the tube 2 clamped, then connect the tube with the system of tubes for agar, close the tank with stopper 4 by means of a lever mechanism 7 and remove the clamp 8 on the main tube between the pressure gauge and tank 1. After This, pumping air into the system to a pressure of approximately 0.2 atm by the right foot, sitting on a stool 43 and pressing the toe on the pedal 38 fill the measuring device with an agar to the upper division of 266 cm. Then take the mattress 18 with his left hand. to cannula 17, insert it right th hand into the neck of the mattress and pushing the pedal heel portion of agar is poured into the mattress to 133 cm, and dividing the t. d.

The subject matter of the invention.

Claims (2)

1. A device for bottling using compressed air liquids, mainly bacteriological nutrient media, using a reservoir for the liquid to be dispensed, communicated through a distribution valve with a measuring vessel, an air-injection device and a receiver for the liquid to be dispensed, characterized by the use of a distributor in the form of two from the pedal 38 spring-loaded clips 12, 12a, of which clip 12 is installed over a tube 8a supplying a liquid to be poured from the reservoir 1 to the measuring device 14, and the tube 166, which discharges compressed air from the measuring device 14 to the atmosphere, and the clamp 12a for the tube 86, which discharges the liquid to be poured from the measuring device 14 to the receiver 18, and the tube 16a, which supplies compressed air to the measuring device from the air pumping device. 2. In the device according to claim 1, use a spare magazine for compressed air in the form of a battery of bottles 35 for injecting air through a pipe provided with a baffle clan 34.
