Description

I

The invention relates to a technique for cleaning products and can be used in mechanical engineering, metallurgy and other industries.

Closest to the invention to the technical essence and the achieved effect is a device for washing products, containing a bath with a drain hole and collectors located therein with nozzles connected to the compressed air supply system U.

The disadvantage of this setup is the complexity and considerable energy consumption for the ejection and circulation of the washing liquid.

The purpose of the invention is to simplify the design and reduce energy consumption.

This goal is achieved by the fact that in an apparatus for washing products containing a bath with a drain hole and located in it collectors with nozzles connected to a compressed air supply system, the collectors nozzles are located 1-100 mm below the drain hole of the bath.

In addition, the installation is equipped with reflectors installed in the bath above the collectors.

The drawing shows schematically a plant for washing products, a general view.

Claims (2)

The installation includes a bath 1, supply pipe 2, and a discharge pipe 3 with a drain hole, a removable cover 5 and reflectors 6 8. Bath 1 is divided into compartments by partitions 9 and 10, which are installed so that between the bottom 11 of the bath and partitions 9 and 10 there is a gap. Collectors 12–17 with 20 cages 18–23 are installed along the bath width below drain hole k at a distance of 1–100 mm in the vertical, preferably 3–0 mm. 3 Under each reflector 6-8, in particular, two or more collectors can be installed in parallel. On adjacent collectors in one of the compartments of the bath, nozzles of one collector can be positioned with a shift, for example, nozzles 18 are installed in a checkerboard pattern with respect to nozzles 19 other collector 13. Installation works as follows. Compressed air supplied to the collectors 12-17 installed in the compartments of the bath, the output through the nozzles 18-23 and the passage through the fluid layer creates a liquid-air jet of the required parameters, which falls on the product being washed, such as wire or mesh. Fresh liquid in the compartments of the bath 1 enters through the inlet pipe 2 and the gap between the bottom 11 and partitions 9 and 10. The contaminated liquid is discharged from the bath through the drain opening and the discharge pipe of the 3 Stroi, which are not reflected by the product being washed, fall into the reflectors 6 -8 Then they fall down from them, washing the product from above and again, and the same compartment flows down. Thus, the product undergoes repeated washing in each compartment, and the liquid in the compartments circulates many times. The parameters defining the positions of the nozzles with respect to the drain hole k are determined experimentally. When lowering the nozzle at a distance of up to 100 mm, washing is carried out efficiently at pressures of 0.17–8 atm. When lowering the nozzles by more than 100 mm, even with a significant increase in air pressure, 5 MPa, washing is ineffective. In this case, the operation of the device is not stable, a strong pulsation of the liquid is observed, which is characterized by periodic ejections of the liquid onto the surface being washed. 04 When lowering the nozzle within 3 mm AO and low air pressure (0.17-0.6 atn), the most effective flushing (), the device operates stably. This unit for jet washing of products, as compared with the known, allows to reduce the consumption of washing liquid, to improve the quality of the washed surface, to exclude the use of acid-resistant pumps with pipelines. The installation is easy to operate. The nozzles of the nozzles are not clogged, since only air passes through the air nozzles and the water is outside the nozzles and collectors. Installing two or more collectors under a single reflector allows you to adjust the parameters of the jets within wide limits, depending on the type of contamination, the type of products and the requirements for the surface to be treated. The location of the nozzles on adjacent collectors with a shift, for example, in a checkerboard pattern, prevents the workpiece from escaping from the zone of impact. Claims 1. A device for washing products comprising a bath with a drain hole and collectors located therein with nozzles connected to a compressed air supply system, which, in order to simplify the design and reduce energy costs, collectors nozzles are located on The distance is 1100 mm below the drain hole of the bath. 2. Installation as claimed in claim 1, which is supplied with reflectors installed in the bath above the collectors. Sources of information taken into account in the examination 1.
