Description

A kind of waste and old CRT monitor surface trimming separating machine

Technical field

The utility model relates to the chemical metallurgy technical field, particularly a kind of waste and old indicating meter surface trimming separating machine.

Background technology

According to the relevent statistics, the social recoverable amount of China's televisor surpasses 400,000,000, and wherein very major part is the product that enters family late 1980s, now to scrapping the time limit.Expectation was from 2003, and China has 5,000,000 above televisors to scrap every year.To the striding forward of informationized society, approximately have 3,000 ten thousand above robot calculator to enter family every year along with country at present, what wherein the display equipment of most computers was used is CRT monitor.CRT monitor is divided into two portions, i.e. panel glass and cone glass, and wherein cone glass contains lead, and lead content is 20-28%, and panel glass is leaded lower or not leaded.CRT is carried out the Environmental-protection recycling recycling, need to separate unleaded panel glass with the cone glass that lead is arranged, make glass and lead all get utilization in the control Lead contamination.The method of disassembling the CRT glass bulb that Present Domestic is studied employing outward can be divided into two classes substantially, and namely physics is disassembled method and chemistry is disassembled method.

Physics is disassembled method and is comprised electrical heating wire method, deformation method, scorification, laser treatment method, and other dividing methods such as hard metal rod, diamond cutting etc.

It is acid system that chemistry is disassembled method, but is a kind of low melting glass of micritization owing to being used for the sintered glass of sealing-in CRT cone panel glass, more soluble in the solution such as nitric acid, hydrofluoric acid.So can adopt the solution such as nitric acid, hydrofluoric acid, organic acid, dissolve sintered glass by the mode of soaking or rinse, and be aided with the separation of thermal shock process implementation CRT using glass bulb.

(1) nichrome wire cutting method.Be the method for utilizing electric-heating-wire-heating quenching thermal stresses to make it to separate, its shortcoming is that sepn process is loaded down with trivial details, and is unstable, and otch is not too neat, need knock after cutting and processes and separate.

(2) thermal deformation method.Add heat shielding, bore the junction, then water is cooling rapidly, makes screen, cone separately.Shortcoming is to obtain complete tube panel, pipe cone assembly.

(3) laser cutting method.The laser automatic cutting device is the patent equipment of Finland Preventia company, this is a cover fully-automatic equipment, the laser that utilizes laser generator to produce separates tube panel, pipe cone, separable unleaded panel glass and the leaded cone glass opened, the cutting and separating face in good order, disintegrate-quality is good, but expensive.

(4) diamond cutting knife patterning method.Be to cut CRT with a pair of cutting knife, its cut surface is neat, but cutters are more expensive, and during cutting, noise is large, and tool wear is serious, is not suitable for industrial application.

(5) scorification.Scorification utilizes the softening temperature of sintered glass lower than the characteristic of cone glass and panel glass, whole glass bulb is heated to the softening temperature of sintered glass, and this moment, cone glass and panel glass were also not softening, pipe is kept certain angle of inclination, can realize boring the natural separation of screen, the operating time of the method is long, generally needs 6～8h.

(6) shield, bore the junction with dissolvings such as nitric acid, hydrofluoric acid, the method for chemical treatment that makes it to separate, subsequent wastewater treatment cost is higher, and efficient is lower.This method is applicable to the manufacturer of CRT picture tube, can continue on for producing new CRT to the defective in quality CRT screen of new production in production line, the component that cone is disassembled after separation.Method of chemical treatment comprises that hot acid sprays and hot acid is bathed two kinds of methods.
