Description

The invention relates to methods for separating solid materials comprising metal reinforcement, for example, reinforced concrete products and T, n, j, and can be used in the regeneration of old and rejected concrete products to separate their metallic armature and concrete mass, followed by crushing the concrete mass to required dispersion and separation of it.

Mechanical methods are known for separating reinforcement from the concrete mass of old or rejected reinforced concrete structures or for removing PPH by crushing for reuse or other use of reinforcement and crushed stone,

However, these methods are non-productive, complex, the processes of mechanical crushing of reinforced concrete materials are accompanied by increased dust emission, which creates a danger to the health of service personnel and reduces the production culture.

The aim of the invention is to increase the production and productivity of the process during the regeneration of old or rejected concrete products.

This is achieved by immersing the concrete products in a water bath and expose electrohydraulic shocks from the discharges to a pre-grounded reinforcement, and after peeling the reinforcement from the concrete mass, the latter is directed to further separation in electrohydraulic crushers.

An example of the use of the proposed method.

Reinforced concrete products are immersed in a water bath, previously in two or three places exposing its armature for earthing or connecting the negative pole of the electrical circuit to it, then, next to electrodes, placed on a trolley going over the top of the bath and located at a distance of 300-500 mm friend

Weighing the entire surface of products across the width must be taken somewhat large,

electro-hydraulically, the diameter of the largest particles, the processing of the product with the discharges, of the material used in the concrete, to the reinforcement through the pores of the concrete, as a result of the separation process

When this happens, intensive reinforcement is obtained, clean

destruction of concrete and flaking-crushed stone or gravel, clean-large

its production from fittings, which allows popesok, cement milk and fine end of passage of electrodes throughout the entire JQ,

select the reinforcement for the product length, remove the uda-process rationally, and assemble the pieces of concrete from the sub-DUJ regime: don bath, direct them to electric U - 40 - 60 kV

hydraulic crushers for complete with 1.0 - 3.0 microfarads,

separation of concrete from rubble and U particles - voltage, kV gravel, C - capacity, in microfarads,

Further separation of concrete. At the same time, energy consumption does not exceed the gravel, gravity and sand are carried out by 2-3 kWh per tonne of reinforced concrete of conventional electro-hydraulic draw-products.
