Abstract

Usage: for cleaning small products of complex configuration with a liquid medium from chips and grease stains. SUMMARY OF THE INVENTION: the apparatus comprises a washing liquid unit, in the upper part of which a working bath is mounted with a conical container for accommodating products. The bath is in fluid communication with a compartment in a tank containing a check valve. The compartment is immersed in a bath and connected to a source of compressed air. The execution of the container conical with the top down ensures mixing of the parts with flows of liquid and air. 4 ill.

Description

The invention relates to techniques for washing and degreasing parts and can be used in mechanical engineering and instrumentation for cleaning small parts from chips and grease.

A well-known washing machine for washing and degreasing parts based on the principle of submerged jets, comprising a bath with a washing solution, a basket with o parts to be cleaned, a pump and nozzles with nozzles. However, this machine does not provide high-quality cleaning of small parts of complex configuration with blind holes.

It is also known that a device for washing articles comprising a washing liquid bath, a washing chamber, a tubular panel with nozzles and means for supplying a washing liquid. This device does not allow high-quality cleaning of parts located in the washing chamber in an unoriented position.

The closest in technical essence is the installation for washing products containing a bath with a washing liquid, a working chamber and a compartment with a check valve immersed in the bath, connected to the working chamber by means of a pressure pipe. A disadvantage of the known installation is that it does not provide high-quality cleaning of small parts of complex configuration with blind holes. This is because the small parts are in an unoriented position and their inaccessible cavities and blind holes cannot be cleaned with directed jets.

The purpose of the invention is to improve the cleaning quality of small parts of complex configuration with blind holes.

The goal is achieved in that in a known installation comprising a tank for washing liquid, a working bath with a holder for parts and a compartment for supplying alternating jets of liquid, according to

According to the invention, the part holder is made in the form of a conical perforated container with holes in the apex of the cone connected to the pressure pipe of the tank compartment. It is because of the inventive design of the container for parts that, with alternating supply of liquid jets to its apex, multiple mixing of parts during washing and their high-quality cleaning are ensured.

1 and 2 show the proposed installation; in Fig.Z - the washing process; figure 4 - filling the compartment.

The installation comprises a bath 1 with a drain channel 2, a conical container 3 and a cover 4. The bath 1 is mounted in the upper part of the washing liquid tank 5. equipped with a partition b and a filter 7. The bath 1 is connected with a pressure pipe 8 and a compartment 9 containing a check valve 10 and step for supplying compressed air 11. An electrical cabinet 12 with a control panel 13 is installed at the rear of the unit.

Installation works as follows.

When compressed air is supplied through the hose 11 to the compartment 9, the washing liquid therein is supplied through the pressure line 8 to the top of the conical container 3. The parts located in the container are repeatedly mixed with the liquid stream. Contaminated liquid is discharged through channel 2 to filter 7 and then to tank 5

The compressed air supply is interrupted. Compartment 9 communicates with the atmosphere. Under the influence of hydrostatic pressure of the liquid column located in the tank 5, the check valve 10 opens, the liquid fills the compartment 9. Compressed air is supplied to the compartment 9. The cycle repeats. Using the proposed technical solution, in comparison with existing technologies, it is possible to improve the quality of cleaning small parts of complex configuration from oil, emulsion and chips, reduce labor costs, and increase the production culture.
