Description

The proposed utility model relates to the field of galvanic coatings and can be used in technological processes that ensure the complete capture of toxic components and return them to production.

One of the important operations in galvanic production is the washing of parts. The purpose of washing is not only to carefully remove the solutions and products from the previous operation from the surface of the products, but also to ensure that they reach the waste water at an economical flow rate. Water after galvanization is a dangerous source of environmental pollution by heavy metal ions, salt components of electrolytes and technological solutions. After each technological operation, the product is sequentially washed in a cascade of water baths and as the products are processed, the content of components from the solution from the main process bath is accumulated in them and, as a result, their concentration in the discharge from the flow-through bath is increased. Upon reaching a certain concentration of components in the wash baths, their contents are pumped to the treatment plant, and the bathtubs are filled with clean water. In industry, the washing process in a sequential cascade of bathtubs is considered the most effective. See book Electroplating in Mechanical Engineering, A Handbook in Two Volumes, Volume 1, edited by Dr. Tech. sciences prof. M.A.Shlugera, M, "Engineering", 1985, pp. 86-89.

The disadvantage of this process is the need to use a large amount of water, which after washing is contaminated with toxic components and this water enters the central treatment plant, requiring huge material costs and occupying large areas.

As a prototype, the installation of jet washing of parts according to the patent of the Russian Federation No. 2054978 with a priority of 05.21.1990 was chosen. The installation includes: a jet bath for washing parts with a drain pipe, device catchers with parts, an actuator for supplying washing liquid, elements for forming jets with nozzle-shaped devices, an actuator for supplying a cleaning medium and sensors for monitoring the processes occurring in the installation. The unit operates in an automatic galvanic coating line.

This installation is complex in design, but the main disadvantage is the need to discharge the used wash water into a central treatment plant.

The objective of this utility model is to create a washing plant for parts used in degreasing, pickling and plating, working in a closed cycle, not requiring centralized treatment facilities.

The problem is solved in that a flushing plant is proposed that contains a container with a drain pipe, in which a fixture with parts is installed, a cleaning medium and pipelines, while the tank is made in the form of a sealed chamber with nozzles installed in it, which are connected through pipelines to a vaporizing chamber connected using pipelines with a tank with distilled water and a condensate accumulator connected to the drain pipe of the sealed chamber, and the vaporizing chamber pa and condensate drain lines are drive, and between the container with distilled water and a pump evaporative chamber, all valves are pipes, and the entire installation is sealed, impermeable to air cleaning media - steam.

The essence of the utility model is illustrated by the drawing, which shows: 1 - chamber, 2 - fixture with parts, 3 - condensate storage, 4 - boiling chamber, 5 - boiling chamber heater, 6 - steam pipe, 7 - nozzles, 8 - distilled water tank, 9 - pump, Cl. 1 ... Cl. 8 valves. Installation works as follows. After the main technological operations (degreasing, etching, galvanic coating, etc.), the parts are placed in the chamber 1 of the washing unit. Water vapor from the boiling chamber 4 through the steam line 6 through the valves Kl6, Kl7 and nozzles 7 enters the chamber 1 and condensing washes the parts in the device 2. The steam-water mixture flushes the solution and flows through the Kl1 valve to the accumulator 3 with the Kl2 valve open and the Kl3 valves closed and Cl8. Upon reaching a certain level of condensate, the valves Kl3 and Kl 8 open, the valves Kl1 and Kl2 are closed, and the condensate flows into the boiling chamber 4. To compensate for the loss of the liquid water phase due to incomplete condensation of steam, a container with distilled water 8 and a line with a pump 9 and Cl5 valve.

As the solution is concentrated in the boiling chamber 4, it, through the Кл4 valve, merges into the process bath. The installation fully implements the principle of closed closed-loop technology and the return of the components of technological baths to production without intermediate operations. The use of the proposed device is especially relevant in the technological processes of chromium plating. In mass production, galvanic plants dump very large volumes of wash water (hundreds and thousands of cubic meters per day) into treatment plants, which have to be treated in central treatment plants.

Thus, obtaining a technical result is achieved in the proposed installation by ensuring that parts are cleaned in closed mode without draining water to treatment plants with little external compensation, which promises large economic profits.
