In the application of daily life, one class fluorescent lamp and LED are designed to be placed in fluorescent tube, the most this fluorescent lamp of people is called daylight lamp, this LED is called LED daylight lamp, daylight lamp model conventional in Common People is T5 and T8, T5 shows a diameter of 5/8ths inches of fluorescent tube, i.e. 16 millimeters, in like manner a diameter of an inch of T8.Along with the propelling of sustainable development of China strategy, 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 needing to reclaim the daylight lamp of substantial amounts, the three primary colors fluorescent powder wherein contained, metal, plastics, glass are all can be with the resource of recycling.
Traditional daylight lamp recovery process mainly uses to cut after fluorescent material is blown at two ends and directly crushes fluorescent tube, carry out selecting crude drugs with winnower the most again, thus reach metal, plastics, glass, the separate purpose of fluorescent material, but, a part of fluorescent material sticks on fluorescent tube, by simply blowing powder operation without departing from cullet, if the most broken fluorescent tube after blowing powder, fluorescent material mixes with cullet, the recovery difficult of glass and fluorescent material will be greatly increased, reduce the fluorescent material and the purity of glass and quality obtained after reclaiming, moreover, also can affect the quality of downstream product manufactured by the glass obtained by recovery, cause waste, original intention against 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, purpose is to provide the disassembly system of a kind of low pressure mercury lamp, solve traditional daylight lamp recovery process after cut end blows powder, i.e. crush the fluorescent material separating difficulty increase that fluorescent tube causes cullet and adheres on cullet, reduce the problem reclaiming product quality.
The present invention is achieved through the following technical solutions:
The disassembly system of a kind of low pressure mercury lamp, 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 in the cleaning machine of recovery workshop, use cleaning machine to be carried out outside fluorescent tube；
(B) use cutting machine that the two ends of daylight lamp are cut in confined space, separate fluorescent tube and two lamp holders, remove the electronic component in fluorescent tube, then it is sent in disintegrating machine crush by electronic component, lamp holder, metal fragment and plastic flakes after crushing are separated, metal fragment and plastic flakes are respectively sent in metal recovery device and plastics recovery device, heating metal recovery device and plastics recovery device, distill the hydrargyrum being adsorbed on metal fragment and plastic flakes；
(C) fluorescent tube behind heating excision two ends, removes the hydrargyrum being adsorbed on fluorescent material and fluorescent tube；
(D) fluorescent tube is put in ultrasound wave pond, start supersonic generator, fluorescent tube is carried out ultrasonic Treatment, reduce the adhesive ability between fluorescent material and fluorescent tube, the fluorescent material departed from fluorescent tube falls into the water, form ultrasonic Treatment liquid in powder, then fluorescent tube is sent into fluorescent tube service sink, tube inner wall is carried out by fluorescent tube service sink, the fluorescent material adhering to tube inner wall is scraped to fluorescent tube rinse water, form fluorescent tube service sink liquid in powder, finally ultrasonic Treatment is contained powder liquid and mix with fluorescent tube service sink liquid in powder and to filter；
(E) fluorescent material obtained after filtering is purified, fluorescent material is mixed with dichloromethane stirring, then use acetone that fluorescent material is washed for several times.In prior art, the recovery process of daylight lamp is: at the two ends of excision daylight lamp, i.e. after lamp holder, blower fan is used to blow the fluorescent material in fluorescent tube off, the most directly crush fluorescent tube, to the cullet produced, metal fragment and plastic flakes carry out selecting crude drugs with winnower, thus reach metal fragment, plastic flakes, the separate purpose of cullet, but, such method is worthless, because some fluorescent material sticks on fluorescent tube, it is without departing from cullet that this part fluorescent material only simply blows powder by blower fan, if the most broken fluorescent tube after blowing powder, the fluorescent material adhered on glass mixes with cullet or glass dregs, use selecting crude drugs with winnower, the methods such as electric separation are difficult to separate them, cullet are greatly increased with the recovery difficult of fluorescent material, the fluorescent material obtained after reducing recovery and the purity of glass and quality；More seriously, also can reduce the quality of downstream product manufactured by the glass obtained by recovery, thus cause waste, against the original intention of the waste and old daylight lamp of recycling.In order to solve the problems referred to above, the invention provides a kind of technique reclaiming waste and old daylight lamp, first, waste and old daylight lamp collection box is placed in each residential block, owing to current promotion efficiency is inadequate, not arranging the collection box of waste and old daylight lamp in a lot of communities, a lot of residents are thrown away in refuse receptacle after even wrapping up waste and old daylight lamp with newspaper.Afterwards collection box is transferred in recovery workshop, take out daylight lamp, transfer them in cleaning machine, its surface is carried out, because the source of daylight lamp is different, antibacterial contained by its surface, dust, mud can increase the burden of subsequent recovery operation, so needing to be carried out the surface of daylight lamp.After cleaning, in confined space, the two ends of daylight lamp are excised, it is to avoid gaseous mercury leaks, and cutter sweep can use the cutting equipments such as single head saw, dual-end saw.After having cut, take out the electronic component within fluorescent tube, it is sent to electronic component together with lamp holder disintegrating machine crushes, after having crushed, metal fragment and plastic flakes are separated, and deliver to respectively, in metal recovery device and plastics recovery device, finally metal recovery device and plastics recovery device be heated, remove the hydrargyrum of absorption in metal fragment, particle fragment.The fluorescent tube being cut off lamp holder is the most heated, is adsorbed in the hydrargyrum on fluorescent tube or on fluorescent material to remove.After removing hydrargyrum,
