Description

A kind of mixing reinforcing bar cutting double teeming method

Technical field

The present invention is the field of metal processing, and in particular to a kind of mixing reinforcing bar cutting double teeming method.

Background technique

Existing building is mostly the combination of armored concrete, and when building faces disassembly & recycling, reinforcing bar can be weighed as one kind The building materials utilized again can utilize again after making certain processing, some recovery methods are directly that reinforcing bar after the recovery is direct Secondary use is put into, certain supporting role is played in interior of building, but reinforcing bar is wrecked by disassembly by a large amount of external force, Certain injury itself is received, there are certain risk, therefore keep reinforcing bar reacquisition tough reinforcing bar recycling again forging Property, preferably guarantee the safety of reinforcing bar.

Summary of the invention

To solve the deficiencies in the prior art, it is an object of the invention to separate reinforcing bar with concrete, weight is carried out to reinforcing bar New forging, improves the toughness of reinforcing bar.

In order to achieve the above objectives, the present invention adopts the following technical scheme that:

A kind of mixing reinforcing bar cutting double teeming method, which comprises the following steps:

S1, the mixing reinforcing bar being recovered to is separated, including concrete separation is separated with muscle body, the mode for first passing through impact will The concrete disintegrating separation on mixing reinforcing bar is sticked in, then the mixing reinforcing bar of initial gross separation is entered in reagent and is impregnated, waiting takes Out;

S2, the mixing reinforcing bar taken out after impregnating are placed in heavy-duty machinery and carry out hammering separation, make to mix concrete on reinforcing bar with Mixing reinforcing bar is completely separated, then the mixing reinforcing bar after separation is placed in assembly line;

S3, mixing reinforcing bar are entered in rapid cutting device by assembly line, are rapidly cut into the biggish mixing reinforcing bar of specification small Block, and assembly line is followed to be transferred in smelting furnace;

S4, mixed solution is obtained after high-temperature calcination in smelting furnace, and appropriate iron powder and reagent is added in mixed solution, It flows into mold and is cooled and shaped again.

Further preferably the time impregnated in the step S1 is greater than 24 hours, connects mixing reinforcing bar sufficiently with reagent Touching dissolution.

Further preferably the reagent impregnated in the step S1 includes hydrochloric acid, sulfuric acid and water, generates rebar surface rotten Erosion changes the contact surface shape with concrete, so that mixing reinforcing bar and concrete preferably separate.

Further preferred, the mass ratio of the hydrochloric acid, sulfuric acid and water is (20-30): (20-30): 50.

Further preferred, the movement speed of the assembly line in the step S2 is 5-8 meters per minute, promotion mixing reinforcing bar Advance.

Further preferably the rapid cutting device in the step S3 is worn thoroughly to be set on assembly line, and is misplaced and put Assembly line is divided into the several segments to differ in size.

The invention has the beneficial effects that: by impact so that mixing reinforcing bar and concrete quick separating, then pass through hydrochloric acid Make to mix rebar surface and generate to corrode with the corrosion of sulfuric acid, then by impact so that mixing reinforcing bar is more fully shelled with concrete From, the rapid cutting device on assembly line is passed through by assembly line, cutting separation is carried out to reinforcing bar, make mix reinforcing bar separation At fritter and the abundant melting in smelting furnace, it is equipped with appropriate iron powder and obtains new bar material.

Specific embodiment

Below in conjunction with detailed description of the invention by specific embodiments.

Embodiment one

A kind of mixing reinforcing bar cutting double teeming method, comprising the following steps:

S1, the mixing reinforcing bar being recovered to is separated, including concrete separation is separated with muscle body, the mode for first passing through impact will The concrete disintegrating separation on mixing reinforcing bar is sticked in, then the mixing reinforcing bar of initial gross separation is entered in reagent and is impregnated, immersion Time is greater than 24 hours, makes to mix reinforcing bar and reagent comes into full contact with dissolution, wait to be removed;

S2, the mixing reinforcing bar taken out after impregnating are placed in heavy-duty machinery and carry out hammering separation, make to mix concrete on reinforcing bar with Mixing reinforcing bar is completely separated, then the mixing reinforcing bar after separation is placed in assembly line, and the movement speed of the assembly line is per minute 5-8 meters, mixing reinforcing bar is pushed to advance;

S3, mixing reinforcing bar are entered in rapid cutting device by assembly line, are rapidly cut into the biggish mixing reinforcing bar of specification small Block, and assembly line is followed to be transferred in smelting furnace, rapid cutting device wears thoroughly and sets on assembly line, and misplaces and put flowing water Line is divided into the several segments to differ in size;

S4, mixed solution is obtained after high-temperature calcination in smelting furnace, and appropriate iron powder and reagent is added in mixed solution, It flows into mold and is cooled and shaped again.

The reagent impregnated in the step S1 of the present embodiment includes hydrochloric acid, sulfuric acid and water, and rebar surface is made to generate corrosion, is changed With the contact surface shape of concrete so that mixing reinforcing bar and concrete preferably separate.

The mass ratio of the hydrochloric acid of the present embodiment, sulfuric acid and water is 20:30:50.

Embodiment two

The present embodiment is similar to embodiment one, and difference is only that the mass ratio of hydrochloric acid, sulfuric acid and water is 30:20:50.

The invention has the beneficial effects that: by impact so that mixing reinforcing bar and concrete quick separating, then pass through hydrochloric acid Make to mix rebar surface and generate to corrode with the corrosion of sulfuric acid, then by impact so that mixing reinforcing bar is more fully shelled with concrete From, the rapid cutting device on assembly line is passed through by assembly line, cutting separation is carried out to reinforcing bar, make mix reinforcing bar separation At fritter and the abundant melting in smelting furnace, it is equipped with appropriate iron powder and obtains new bar material.

The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should Understand, the above embodiments do not limit the invention in any form, all obtained by the way of equivalent substitution or equivalent transformation Technical solution is fallen within the scope of protection of the present invention.
