Description

The invention relates to the liquid treatment of products in baths and can be used, for example, to wash products after electroplating, chemical and anodizing coatings.

Installations are known for the processing and washing of avt.Sv. No. 1196417, 494203, 548324, 1013000. The disadvantage of these systems is the considerable water consumption for washing the products.

The known system of cascade washing products (see the book I. Telnova Technologists cleaning and washing of agricultural machines M., 1975, p. 164-166). This system has the advantage of reducing the water consumption for flushing, however, with continuous production

requires significant water consumption (for example, at the Red Excavator factory in the chrome plating line of hydraulic cylinders, the water consumption during cascade washing is about 900 m3 / day). The consumption of industrial water can be reduced by increasing the number of baths (see Guide materials. Use of water for washing products in electroplating, M., 1970).

However, an increase in the number of wash baths leads to an increase in production space, additional labor costs for moving products.

The aim of the invention is to improve the economy by reducing

discharge of heavy metals and reduction of wash water consumption.

FIG. 1 shows the scheme of lines, a general view; in fig. 2 shows the layout of the units under the process bath.

The device includes a processing bath 1 and a 2,3,4,5 cascade countercurrent washing bath interconnected by overflow pipes, a displacement assembly 6, a hinge 7 mounted on a monorail 8, Lini also contains a pallet 9 placed above bath 1, above which is installed nozzle 10 compressed air. The pallet 9 is connected to a vibrating device 11. Near the pallet is mounted on support 12 a rocker arm 13, connected by a rod 14 with an electromagnet 15. One part of the rocker arm is located near the pallet 9, the other is near the pallet 16, located inside the intermediate chamber 17, 18, and a drain is also provided in the accumulator 19, connected by means of the actuator 20 to the bath 1. A baffle plate 21 is installed on the wall of the bath 1. In the upper part of the chamber 17 there is also a pan 22, which is connected to a vibrating plate. unit 23. Near the pallet 22, the form-: unit of water supply 24 and air 25 is installed. The nozzle 24 is connected by means of a pump 26 to the bath 2.

The work of the line is as follows.

The parts placed in the hitch 7 by means of the displacement unit 6 are electroplated in the electroplating bath 1, removed from the electrolyte and kept above the bath 1 to drain the excess electrolyte, after which they are transferred to the pallet 9, then the vibrating device 11 is turned on, compressed air is fed into the tank 10, there is a further release of the sample with the details from the residual water. Subsequently, the vibrator 11 is turned off and the air supply to the nozzle 10 is stopped. Then the electromagnet 15 is activated and the hitch 7 moves along the rocker from the first pallet to the second pallet 16 into the intermediate chamber 17 above the dipping tank 18. Thus, the dipping of the sample into the container 18 occurs, and the value of the container 18 is slightly more than the value of the sample. Next, the electromagnet 15 is activated and the hitch is moved from the pallet 16 to the pallet 22 by means of the rocker arm. The liquid flows down from the hitch, then the vibrating device 23 is turned on, then water is supplied to the nozzle 24 and then the air to the nozzle 25.

The use of the line for liquid OD-processing of products allows to reduce the water consumption for washing the products by 100-150 times in comparison with the existing washing devices, and also excludes

or significantly reduce the discharge of waste water containing heavy metals to local wastewater treatment plants. The reuse of wastewater for charging the electroplating bath and adjusting the electrolyte makes it possible to return 90-100% of non-ferrous metals to production.
