Abstract
The present invention relates to a recovering and regenerating technology for waste foamed plastic products, which comprises the steps that the waste foamed plastic products in a crushing and washing machine set are crushed and are washed by washing agent water at the same time; then, the waste foamed plastic products are discharged to a cleaning, dewatering and drying machine set to clean and clear the washing agent and other adhesive substances; after the waste foamed plastic products are dewatered and dried, the waste foamed plastic products are transported to a melting machine set to be melted at high temperature; after the waste foamed plastic products are plasticized, the waste foamed plastic products are transported to a regenerating granulator set and are granulated, and waste white pollutants are changed into a recoverable reutilization resource. After the discharged washing agent sewage and solid sundries are separated, the discharged washing agent sewage and the solid sundries are purified for a fertilizer preparing technology. The whole process is scientific and reasonable, the white pollution is radically treated in a no pollution mode, the living environment of people is improved, and the problem of white pollution is effectively solved.
Description
The invention belongs to the recovery technology of high molecular polymer, be specifically related to a kind of reclaiming method of waste foamed plastic product.
Foam plastic product such as disposable household electrical appliances wrapping material, industrial packaging material and fast food etc. since with after promptly abandon, the person who abandons is not perishable again, therefore becomes one of important source of pollution of present society, is referred to as " white pollution ", seriously influence people's quality of life and social environment, this pollutant quantity is big, and weight is little, and volume is big, be not easy to transportation, also do not have a kind of method of simple and easy to do recycling so far.In the prior art as patent CN1080645A, though adopt liquid medium high temperature hot melt froth breaking, but its complex process, select deleterious solvent xylene for use, during operation, secondary pollution is serious, and for example patent CN1043323A " uses continuous catalytic cracking method for reclaiming waste foam polystyrene ", this method is with behind the waste foam polystyrene hydrocarbon dry type removal of contamination, add in the pulverizer, be crushed to the bulk below 30 millimeters, add then in the implanter, inject the cracking case after the fluidisation of heating, carry out catalytic pyrolysis.This method reclaims the method for waste foam polystyrene, complex process, and service temperature height, and not only energy consumption is big, but also can influence the performance that reclaims raw material.
The object of the present invention is to provide the reclaiming method of the simple waste foamed plastic product of a kind of technology.
The reclaiming method of waste foamed plastic product of the present invention is characterized in that may further comprise the steps successively:
Waste foamed plastic product is joined in fragmentation, the washing unit, under the delivery of the current that contain washings, enter the spin shredder assembly, these float over the mutual impact that waste foamed plastic product on the washings is subjected to high-rate cutting, stirring action and the washings of high speed rotating tool, in fragmentation, obtained powerful cleaning function, its surface repeatedly contacts with washings repeatedly, makes greasy dirt impurity fully be dissolved in the washings; Through fragmentation, waste foamed plastic product after the washing is admitted to the screening part, do not reach the broken large size foam plastic product that requires and send shredder assembly automatically back to once more by above-mentioned flow process circulation continuation fragmentation, washing, fully broken small size foam plastic product then is admitted to the cleaning and dewatering drying unit, remove residual washings with clear water, dehydrate and be sent to fusing behind the moisture contained in the scumming plastics and extrude unit, foam plastic product is joined extruding filter forcibly, 150--180 ℃ of fusing down, behind elimination micro-foreign material wherein, be added in second forcing machine, make the strip material of suitable dimension by die head, behind the tank cooling and shaping, deliver to the granulation of regeneration and granulation unit; And the spent scrub stream of discharging from broken, washing unit removes by filter to return behind the solid-state foreign material that wash out in the waste foamed plastic product in the washings treatment unit and recycles in fragmentation, the washing unit, is sent to the circulating water treatment unit and carries out purifying treatment replenishing spent scrub stream that new washings postposition swaps out.
Adopt the reclaiming method of waste foamed plastic product of the present invention, technology is simple, has very realized making depleted white pollution thing to become the recyclable resource of utilizing again effectively; Adopt greasy dirt and pollutent in nontoxic washing composition and some auxiliarys removal waste foamed plastic product, free from environmental pollution, and the washing composition sewage of discharging send purifying treatment and fertilize preparation craft with solid sundries after separating, whole flow process is scientific and reasonable, realized pollution-free radical cure white pollution, improve people's living environment, solved the problem of white pollution effectively.
Be described further below in conjunction with the reclaiming method of accompanying drawing waste foamed plastic product of the present invention:
Fig. 1 is the process flow diagram of the reclaiming method of waste foamed plastic product of the present invention.
As shown in Figure 1, the reclaiming method of waste foamed plastic product of the present invention, be that waste foamed plastic product is joined fragmentation, the washing unit 2 from dog-house 1, under the delivery of the current that contain washings, enter spin shredder assembly wherein, these float over the mutual impact that waste foamed plastic product on the washings is subjected to high-rate cutting, stirring action and the washings of high speed rotating tool, in fragmentation, obtained powerful cleaning function, its surface repeatedly contacts with washings repeatedly, makes greasy dirt impurity fully be dissolved in the washings; Through fragmentation; waste foamed plastic product after the washing is admitted to screening part wherein; do not reach the broken large size foam plastic product that requires and send shredder assembly 2 automatically back to once more by above-mentioned flow process circulation continuation fragmentation; washing; fully broken small size foam plastic product then is admitted to cleaning and dewatering drying unit 3; remove residual washings with clear water; dehydrate the contained moisture of scumming plastics and extrude unit 6 after feeding mouth 5 is delivered to fusing; 150--180 ℃ of fusing down; behind elimination micro-foreign material wherein, be added in second forcing machine 7; make the strip material of suitable dimension by die head 8; behind tank 9 cooling and shapings, deliver to regeneration pelletizer 10 granulations: and from fragmentation; removing by filter the solid-state foreign material that wash out in the waste foamed plastic product in washings treatment unit 4 after, the spent scrub stream of discharging in the washing unit 2 returns fragmentation; washing recycles in the unit, can deliver in the special circulating water treatment unit and carries out purifying treatment replenishing spent scrub stream that new washings postposition swaps out.
