Description

The invention relates to equipment for cleaning and washing vessels, such as ampoules, in particular to devices for cleaning vessels. The known devices for pointer purposes are made in the form of a vacuum washing apparatus with a washing tank, a tank for collecting used water, pipelines with remote control valves and a control device. However, such devices consume a lot of electricity and water. To reduce energy consumption in the proposed device, annular manifolds are mounted inside the washing tank. They are connected to steam and water supply pipelines. On the water supply collector there are injection nozzles, and on the bottom of the washing tank there is a vertical annular partition. FIG. 1 is a diagram of the proposed device; in fig. 2 - washing tank in section. The device contains a washing tank I with a lid 2. With the help of a pipeline equipped with an actuator - valve 3, the tank is connected to a steam generator 4. The pipeline has a spout - output to the atmosphere through IS-1Olnite, Aiyy mechanism 5 and filter 6. Pipelines with a valve 7 and 8 connect the tank with pressure tanks 9 and 10 equipped with jackets or coils for heating, as well as a drain tank | {. In addition, the tank has a vacuum gauge 12, a pipeline with a valve 13 for introducing water, and a start button 14. Inside the tank is the sensor 15 gauge. The cover 2 is provided with pneumatic cylinder 16. The automatic operation of the valves, actuator 5, pneumatic cylinder 16, sensor 15 and vacuum gauge 12 is carried out remotely using a control device - a programming unit 17. Inside the tank, a ring collector 18 for steam supply is fixed with eyelets 19 for fastening interchangeable stops 20, on which the cassette 21 with vessels, for example, ampoules 22, is installed. The manifold holes are directed upwards and into the middle of the reservoir. voara. A ring-mounted water supply manifold with injecting nozzles 23, the nozzles of which are directed downwards, in the middle of the tank, is also installed there. On its bottom there is a vertical annular partition 24 reinforced, forming an inner cup 25 and an outer barrel 26.

The pipeline connecting the bowl 25 with one compartment of the drain tank 11 formed by the partition 27 has a valve 28, and the pipeline connecting the bowl 26 with the other compartment of this tank is valve 29. The tank And with the drain holes 30 and 31 are installed in both compartments on the supports 32. A bracket 33 is attached to one of them, which secures the opening of the pneumatic cylinder 6. On the vkutfenny side of the cover 2, a disk 34 is fixed, limiting the movement of the ampoules upward from the cartridge during the water hammer during the filling of the ampoules. The lid 2 of the washing tank is balanced by a counterweight 35.

The device operates as follows. The cassette 21 is loaded with neck-vials. us down, placed on the lugs 20 and pressing the start button 14 turn on the device. According to the signal from programming unit 17, the pneumatic cylinder 16 closes tank I with lid 2, then the emulsion is supplied from it to valve 3 and a sharp stream of water vapor is displaced into the tank 1 through the manifold 18, displacing air from there. Through valve 13 and nozzle 23, sprayed cold water is injected into the vapor medium. The steam condenses and a vacuum is created inside the tank. This very tip sucks air from the vessels - ampoules 22.

The remaining vacuum inside the tank is quenched by iodine a new portion of steam and injected with water.

The above process is repeated two times. The frequency of cycles depends on the volume of vessels being cleaned.

After water is injected through valve 7 from tank 9 into tank 25, desalted tap water with a temperature of 70-EO C is fed. 18. Due to the vacuum in the vessels, created by the co-exposure to them in them with steam, they are intensely filled with a washing liquid coming from the bowl. Filling is accompanied by a water hammer. To completely destroy the vacuum, the collector 18 is again fed

the steam inside the tank I. At the same time, the rest of the washing liquid, which was not collected by the cleaning fluid from the bowl 25, is freely drained through valve 28 into drain tank P. After complete draining, the steam supply stops, and sprayed cold water is injected through valve 13 and nozzle 23.

The vapor inside the tank is condensed, and a vacuum is created in it, in which the washing liquid with a temperature of 70-90 ° in ampoule vessels boils rapidly and is ejected from them. When it boils inside the ampoules, there is an intense destruction of the molecular film and peeling of particles from the inner walls of the vessels being cleaned. They are ejected from the vials along with boiling liquid. The complex physicochemical effects of steam and vacuum, in addition to cleaning the walls of glass and other mechanical particles, also destroy microorganisms. Then steam is again supplied to reservoir I through collector 18 and the cycle can be repeated.

For the subsequent rinsing of the vessels into the bowl 25 through valve 8, distilled water is supplied from the pressure tank 10. The cleaned vessels are dried and sterilized by alternating the steam and cold water injection into the tank.

Before opening the cover 2 at the end of the cleaning process, through the valve 5 and the filter 6, the tank I communicates with the atmosphere.

All vessel cleaning operations are carried out according to the instructions of the programming unit 17, adjusted in accordance with the described process, using a level sensor 15 and a vacuum gauge 12.
