Description

one

The invention relates to the washing of products from technological contaminants and can be used in engineering and repair enterprises, as well as in the electronics industry for cleaning radio components from residual resinous fluxes after soldering and tinning.

The known method of washing products by successive immersion in a two-well liquid containing water and an organic solvent 1.

The disadvantage of this method is low cleaning efficiency.

A device for washing is known, including a washing chamber in which there is a washing area for dipping products, a jet washing zone and a platform for placing products, which is made up and down 2.

A disadvantage of the known washer is the increased consumption of the washing medium and the lack of washing efficiency due to the fact that the flammable medium is quickly polluted.

A device for washing products is known, which comprises a washing chamber with a lifting and lowering platform for placing products and a set of filters 3.

A disadvantage of the known device is the low washing efficiency.

The purpose of the invention is to reduce the consumption of 5 solvents and increase the washing efficiency.

The goal is achieved by the method of washing products and regenerating a working agent, consisting in that they are successively immersed from cases and into a two-layer liquid having a different specific gravity, one of the layers of which contains organic solvent and regenerates it by filtering it, The organic solvent is regenerated in two steps by bleeding up the contaminants with a high specific gravity liquid, and the filtration is performed after draining.

Claims (3)

A device for carrying out the method of cleaning products 20, comprising a washing chamber with a lifting and lowering platform for positioning products — and a filter, has means for placing a filter in the washing chamber, made in the form of a sleeve with reciprocating DRIVE. FIG. 1 shows an apparatus for carrying out the method; in fig. 2 - rod with a platform for placing products; in fig. 3 - device for washing products; in fig. 4 - filter. Example. Water 2 and solvent 3 are poured into the washing chamber 1 (when the valve 4 is closed). The rod 5 performs reciprocating movements first below the section 6 line (in water), then above the section 6 line (in a solvent). Contamination 7 with a specific gravity greater than the specific gravity of the solvent is collected in the lower part of the washing chamber, where, after opening the valve 4, it is discharged together with water. Thereafter, water 2 is poured into the washing chamber 1 again, and after separation, the process continues. Products are placed on platform 8, which is a container with perforated walls and a bottom. The platform 8 is connected to the brush 5. The device for carrying out the proposed method comprises a washing chamber formed by the housing 9 and the cover 10 with a hole for the rod. The lid 10 is made of two parts to provide input and output from the washing chamber of the platform with IDs (not shown in Fig. 3). The washing chamber has a drain pipe 11 with a valve 12. The filter consists of a shell with metal 13 and fabric 14 sieves fixed on it. The washing process associated with the discharge of contaminants with water is described above. Cleaning the washing chamber from soils with a specific weight equal to or less than the specific gravity of the solvent (for example, residues of resin fluxes on radio components) is performed as follows. When the solvent is contaminated, the platform with articles using a rod (not shown) is removed from the washing chamber into which the filter 15 is lowered, after which, since the filter 15 shields the solvent from contamination, the process continues. When the solvent is contaminated again, the next filter is lowered, etc. several times. Then open the lid, remove the platform with the products with the help of a brush, remove the filters 15, For example, using the sleeve 16, open the valve 12 and drain the washing liquid. The valve 12 is closed, fill the washing chamber with water and solvent, clean the filters and the washing process continues. Washing according to the proposed method reduces the consumption of scarce solvents (e.g. gasoline, kerosene) due to their repeated use and increases the efficiency of washing due to the fact that large soils are washed off with water and the solvent is periodically filtered. Claim 1. A method of washing products and regenerating a working agent, which consists in sequentially immersing products in a two-layer liquid having a specific specific gravity, one of the layers of which contains an organic solvent, and regenerating it by filtering it, characterized in that increasing the efficiency of purification, regeneration of the organic solvent is carried out in two steps by blending the contaminants together with a liquid with a higher specific gravity, and filtration is performed after draining. 2. A device for carrying out the method of cleaning products according to claim 1, comprising a washing chamber with a lifting / lowering platform for placing products and a filter, characterized in that it has means for placing the filter in the washing chamber, made in the form of a sleeve with a return-drive drive forward movement.
