Description
Technical field
The present invention relates to a kind of daylight lamp recovery process, be specifically related to reclaim the work of discarded fluorescent tube fluorescent material middle rare earth metal
Skill.
Background technology
Since T.A. Edison in 1879 manufactures carbon fibre electric filament lamp, electric filament lamp with swift and violent speed replace oil lamp,
Wax candle, becomes necessary illuminator in people's life.Along with the development of science and technology, electric filament lamp can not meet the need of people
Ask, although invented volume and the less halogen tungsten lamp of auroral poles that declines afterwards, but the principle that electric filament lamp relies on tungsten filament luminous makes it
Luminous efficiency is the most on the low side.In order to save the energy, fluorescent lamp and the LED of high-luminous-efficiency are arisen at the historic moment.
In the application of daily life, a class fluorescent lamp and LED are designed to be placed in fluorescent tube, and people claim this respectively
Planting fluorescent lamp is daylight lamp, and this LED is called LED daylight lamp, and daylight lamp model conventional in Common People is T5 and T8, T5 table
A diameter of 5/8ths inches of bright lamp pipe, i.e. 16 millimeters, in like manner a diameter of an inch of T8.Along with sustainable development of China plan
Propelling slightly, the requirement to saving the energy is more and more higher, and the popularity of daylight lamp or LED daylight lamp increases the most year by year.But,
After daylight lamp breaks down, just need to reclaim the daylight lamp of substantial amounts, the three primary colors fluorescent powder wherein contained, metal, plastics, glass
It is all can be with the resource of recycling.
Traditional daylight lamp recovery process mainly uses to cut and directly crushes fluorescent tube after fluorescent material is blown at two ends, carries out the most again
Selecting crude drugs with winnower, thus reach metal, plastics, glass, the separate purpose of fluorescent material, but, a part of fluorescent material is to stick to fluorescent tube
On, by simply blowing powder operation without departing from cullet, if the most broken fluorescent tube after blowing powder, fluorescent material mixes with cullet
It is combined, the recovery difficult of glass and fluorescent material will be greatly increased, reduce the fluorescent material and the purity of glass obtained after reclaiming
And quality, moreover, also can affect the quality of downstream product manufactured by the glass obtained by recovery, cause waste, against
The original intention of the waste and old daylight lamp of recycling.
Summary of the invention
The technical problem to be solved is the defect for current waste and old daylight lamp recovery process, it is therefore intended that carry
For reclaiming the technique of discarded fluorescent tube fluorescent material middle rare earth metal, solve traditional daylight lamp recovery process the most broken after cut end blows powder
Broken fluorescent tube causes cullet and the fluorescent material separating difficulty adhered on cullet increases, and reduces the problem reclaiming product quality.
The present invention is achieved through the following technical solutions:
The technique reclaiming discarded fluorescent tube fluorescent material middle rare earth metal, comprises the following steps:
(A) use in residential block waste and old daylight lamp collection box that waste and old daylight lamp is reclaimed, and be transferred to be arranged on recovery
In the cleaning machine in workshop, cleaning machine is used to be carried out outside fluorescent tube；
(B) ClO 2 solution is used to carry out disinfection to outside daylight lamp；
(C) sieve according to the extent of damage of daylight lamp: lamp holder, electronic component are damaged but the daylight lamp that remains intact of fluorescent tube
Send in step (D) and process, intact for lamp holder, electronic component, but there is the daylight lamp of fragmentation in fluorescent tube, reclaims its lamp holder and electricity
Sub-element, collects the fluorescent tube of fragmentation, by selecting crude drugs with winnower separation fluorescent tube and fluorescent material, is all intact for lamp holder, electronic component, fluorescent tube
, cause fluorescent material to come off and the daylight lamp of cisco unity malfunction for a long time for no other reason than that having used, its whole lamp is reclaimed；
(D) use cutting machine that the two ends of daylight lamp are cut in confined space, separate fluorescent tube and two lamp holders, remove lamp
Electronic component in pipe, then is sent in disintegrating machine crush by electronic component, lamp holder, will broken after metal fragment and
Plastic flakes is separated, and metal fragment and plastic flakes are respectively sent in metal recovery device and plastics recovery device, add thermometal
Withdrawer and plastics recovery device, distill the hydrargyrum being adsorbed on metal fragment and plastic flakes；
(E) fluorescent tube behind heating excision two ends, removes the hydrargyrum being adsorbed on fluorescent material and fluorescent tube；
(F) fluorescent tube is put in ultrasound wave pond, start supersonic generator, fluorescent tube is carried out ultrasonic Treatment, reduce fluorescence
Adhesive ability between powder and fluorescent tube, the fluorescent material departed from fluorescent tube falls into the water, and forms ultrasonic Treatment liquid in powder, then will
Fluorescent tube service sink sent into by fluorescent tube, is carried out tube inner wall, the fluorescent material adhering to tube inner wall in fluorescent tube service sink
Scrape to fluorescent tube rinse water, form fluorescent tube service sink liquid in powder, finally ultrasonic Treatment is contained with fluorescent tube service sink containing powder liquid
Powder liquid mixes and filters.
In prior art, the recovery process of daylight lamp is: at the two ends of excision daylight lamp, i.e. after lamp holder, uses blower fan
Blow the fluorescent material in fluorescent tube off, the most directly crush fluorescent tube, cullet, metal fragment and the plastic flakes produced is carried out wind
Choosing, thus reach metal fragment, plastic flakes, the separate purpose of cullet, but, such method is worthless, because of
Sticking on fluorescent tube for some fluorescent material, it is to take off that this part fluorescent material only simply blows powder by blower fan
From cullet, if the most broken fluorescent tube after blowing powder, the fluorescent material adhered on glass is blended in one with cullet or glass dregs
Rising, the method such as selecting crude drugs with winnower, electric separation of use is difficult to separate them, and cullet are greatly increased with the recovery difficult of fluorescent material, reduce
The fluorescent material obtained after recovery and the purity of glass and quality；More seriously, the glass institute obtained by recovery can also be reduced
The quality of the downstream product manufactured, thus cause waste, against the original intention of the waste and old daylight lamp of recycling.Above-mentioned in order to solve
Problem, the invention provides a kind of technique reclaiming waste and old daylight lamp, first, places waste and old daylight lamp in each residential block and reclaim
Case, owing to current promotion efficiency is inadequate, does not arrange the collection box of waste and old daylight lamp in a lot of communities, a lot of residents are even
Thrown away in refuse receptacle after wrapping up waste and old daylight lamp with newspaper.Afterwards collection box is transferred in recovery workshop, takes out daylight
Lamp, transfers them in cleaning machine, is carried out its surface, because the source of daylight lamp is different, and thin contained by its surface
Bacterium, dust, mud can increase the burden of subsequent recovery operation, so needing to be carried out the surface of daylight lamp.Clean complete
After, use ClO 2 solution to carry out disinfection to outside daylight lamp.Traditional technique typically uses ultraviolet sterilization technique, but
Ultraviolet sterilization not only due to ultraviolet penetration capacity is weak and cause sterilizing ability general, and, some antibacterials such as spore bar
Spore produced by bacterium is that ultraviolet sterilization is not removed.Waste and old daylight lamp because of according to source difference, more or less can
With antibacterial, if store in collection box improper, in conjunction with certain environmental condition such as temperature, humidity etc., it is easy to grow Soviet Union
The antibacterial of the bacillus such as cloud gold bacillus cereus, bacillus subtilis.The antibacterial of bacillus is different from general antibacterial, energy
Enough formation spore in the environment being unfavorable for self, spore has resistivity to many sterilizations means, and such as, spore can support
Anti-a lot of antibacterials overpowering ultraviolet sterilization operation.Bacillus cereus can increase the difficulty of follow-up daylight lamp recovery process, sternly
Also the downstream product manufactured by the material after reclaiming can be impacted during weight.In order to solve the problems referred to above, the present invention is cleaning
The outer rear flank of complete daylight lamp, uses ClO 2 solution to carry out disinfection the outside of daylight lamp, and ClO 2 solution is as disinfectant
It is possible not only to kill almost all microorganisms, including spore, but also is the safe and nontoxic green disinfectant generally acknowledged in the world
Agent, after being sterilized by ClO 2 solution, the antibacterial on daylight lamp surface is completely removed.
After completing disinfection by chlorine dioxide operation, it is sent to daylight lamp sieve platform, carries out according to the extent of damage of daylight lamp
Screening.In traditional daylight lamp recovery process, some processes whole daylight lamp is directly carried out fragmentation then selecting crude drugs with winnower separation metal,
Plastics, fluorescent material and cullet；Some processes, after taking out electronic component, lamp holder, crushes fluorescent tube and electronic component, lamp respectively
Head.Such technique is worthless, because the daylight lamp extent of damage is different, its corresponding process technique also can be different, all
Impose uniformity without examining individual cases according to the same processing mode, if the process imposed uniformity without examining individual cases is simple, then for the daylight that damage situations is complicated
Lamp recovering effect is bad；If it is not the process imposed uniformity without examining individual cases is complicated, impaired serious, by simply screening with regard to energy for itself
The daylight lamp directly reclaimed, its cost recovery increases.Such as, daylight lamp is fluorescent tube fragmentation, but its internal electricity
Sub-element is intact, if using directly broken mode, then intact electronic component is just taken as the electronics unit broken down
Part and crush, finally become metal fragment and reclaim, the most again these metal fragments processed, process and obtain new electronics
Element, this is to waste very much resource.In order to solve the problems referred to above, the daylight lamp after cleaning sends into screening platform, by daylight lamp
It is divided three classes according to damage situations: lamp holder, electronic component damages but the daylight lamp that remains intact of fluorescent tube is sent in next step
Row cutting two ends, after its step can be described in detail in detail；Intact for lamp holder, electronic component, but there is the daylight lamp of fragmentation in fluorescent tube, selects
And its lamp holder of recycling and electronic component, collect the fluorescent tube of fragmentation, unified carry out break process, by selecting crude drugs with winnower separation fluorescent tube
With fluorescent material, owing to fluorescent tube has crushed, lose without the fluorescent material being adsorbed on fluorescent tube, so
Screening substantially is carried out by simple selecting crude drugs with winnower；It is all intact for lamp holder, electronic component, fluorescent tube, for no other reason than that using
Cause fluorescent material to come off and the daylight lamp of cisco unity malfunction for a long time, its whole lamp is reclaimed, make by adding fluorescent material
