Description

(5) METHOD FOR WASHING THE INTERNAL SURFACE OF CAPACITY.

one

The invention relates to a washing technique and can be applied in enterprises of machine-building, chemical and other industries.

A known method of cleaning containers by washing with a solution of a collector reagent and a modifying reagent in distilled water, followed by removing the solution from the tank, in which the solution is pre-saturated with neutral gas under pressure, is fed into the tank being cleaned, held to ensure that the surface of the soil particles is hydrophobic and removed from the tank when the pressure is reset to a value less than the saturation pressure 1 1.

The disadvantage of the method is the selective action of the collector reagent and the modifier reagent on a specific group of materials, while in the tank being washed there are several types of contaminants, for example sand dust, pile, steel, aluminum sawdust, rubber pieces, etc. Thus, the known method allows effective cleaning of contaminants of a certain type, while the separation and transportation of particles of contaminants of other species from the tank. The drugs are not produced intensively enough. In addition, the corrosive activity of these detergent compositions limits their use in cleaning processes.

There is a known method of washing the inner surface of the container, which consists in the action of jets of washing liquid on the surface being cleaned and its subsequent suction with a periodic change in the orientation of the container during the washing process 2.

However, in the process of accumulation of liquid, before it is drained from it onto the lower panel of the container, sediment of suspended particles occurs, which, when developed longitudinally transversely in the details of the container being cleaned, is removed even if unsteady fluid movements are created when it is drained due to the presence of many stagnant zones inside capacity. This reduces the effectiveness of the wash. The purpose of the invention is to improve the quality of washing. This goal is achieved by the fact that the method of washing the inner surface of a vessel, which has a complex shape, consists in the effect of jets of washing liquid on the surface being cleaned with its subsequent suction with a periodic change in the orientation of the container in the process of washing, capacity they are divided into two isolated cavities by a horizontal hermetic septum and are subjected to a stream of washing liquid successively in each cavity, and the exhausted suction is performed from the horizontal The partition. The drawing shows the capacity. Inside the washable tank 1, washing nozzles 2 and 3 and suction devices A and 5 are installed. Fill the container half with an aqueous detergent solution at a temperature, stearic acid is introduced in an amount o6e "which forms a layer of stearic acid 6 mm thick on the surface of the liquid, and is cooled washing liquid. As a result of cooling, an even layer of hardened acid is formed, which divides the container into two isolated cavities A and B. The cavity A is rinsed, feeding washing liquid through nozzle 2 and sucking it to form an even surface OTcacciation device k. Upon reaching the pre-set cleaning degree of cavity A, the suction is stopped from it, completely filled with liquid, and capacity 1 is turned over by 180, so that the upper position is occupied by cavity B. The cavity B is washed with the help of nozzle 3 and suction device 5, and the filling before it is washed, the layer of stearic acid is re-melted and removed by suction, organizing a liquid intake in the form of a funnel. All liquid is drained, rinsed and dried capacity. Residues of stearic acid are removed by dissolving, for example, by rinsing with ether. This diaphragm is formed not only by curing the liquid component. It can be made in the form of a film, which is installed inside the container during its assembly, and after washing it is removed, for example, by dissolution. The method makes it possible to increase the washing efficiency by improving the transport of soil particles by the flow of liquid to the suction devices. The invention of the method of washing the inner surface of a vessel having a complex shape consisting in the action of jets of washing liquid on the surface being cleaned and its subsequent suction with a periodic change in the orientation of the vessel during the washing process, characterized in that, in order to improve the quality of the washing, the tank is divided into two isolated cavities by a horizontal hermetic septum and are exposed to a stream of washing liquid successively in each cavity, and the exhausted suction is carried out with a horizontal partitions.
