Abstract

The invention discloses a water purification cycle process in modified reprocessed plastic production, relating to the technical field of sewage purification. The water purification cycle process comprises the following steps: (1) configuring a filtering tank, a precipitation tank and a water reservoir with appropriate areas according to production demands, and introducing wastewater produced in production into the filtering tank through a pipeline; (2) putting an appropriate amount of precipitant into the filtering tank to ensure that impurities in water precipitate, and standing the water in the filtering tank for a certain period of time; (3) putting the water into the metal precipitation tank after the precipitation is ended, and putting alkali and polyacrylamide into the metal precipitation tank, so that waste water undergoes reactions; (4) after the reactions are ended, pumping the wastewater into a plate-and-frame filter press by using a high pressure pump, filtering off metallic impurities in the wastewater by the plate-and-frame filter press, and enabling the filtered water to flow into the water reservoir, wherein filter cakes are used for refining; and (5) testing pH value of water in the water reservoir, adjusting pH value according to the actual testing result, and supplying water to production equipment by a water pump as required after the pH value is adjusted to be qualified.

Description

Water decontamination cycle technique in modification regeneration plastics-production
Technical field
The present invention relates to sewage purification technology field, be specifically related to water decontamination cycle technique in a kind of modification regeneration plastics-production.
Background technology
The store battery that automobile, electric bicycle use is at present mainly lead acid cell, and it is with low cost, manufacturing process is simple, occupy an leading position in electric bicycle market, and 2011, when the output of national lead acid cell has reached 2.4 hundred million kilovolt-amperes.Be the time of a year and a half to two year the work-ing life of the lead acid cell of automobile, electric bicycle, although while production in strict accordance with process control quality, can thereby a lot of batteries all can agingly shorten its work-ing life after half a year.Waste and old automobile, electric bicycle lead acid cell cumulative year after year, total amount is huge, and environment is made a big impact.
For the discarded lead acid cell of scientific and normal recovery, country has set up special recovery market.The recovery of lead acid cell comprises the step such as recycling, the separation of acid solution of plumbous recovery, shell.The shell of lead acid cell is taking PP as main, so the development of the recycling technology of PP shell not only provides safeguard for the long-run development of electric bicycle lead acid cell industry, economizes in raw materials especially and the requirement of the Sustainable development that resource secondary utilizes.
Lead acid cell recovery and utilization technology has a lot of reports at present, China Patent No. is CN101608264, a kind of recovery method of lead acid cell scrap lead is disclosed, China Patent No. is the recovery method that CN101613803 discloses a kind of lead acid cell lead plaster, China Patent No. is CN101173326, discloses a kind of recovery method of the acid waste liquid that reclaims plumbous process generation.The processing steps such as the reprocessed plastic(s) prepared of tradition recovery method all need through melting, extrude, tie rod, cooling, cutting, granulation, again adding also needs many plastic grains again to melt man-hour, and processing step is loaded down with trivial details, and resource consumption is many, and cost is high.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of and reduces costs, reduces resource, improve water decontamination cycle technique in the modification regeneration plastics-production of plastic quality.
Technical problem to be solved by this invention realizes by the following technical solutions:
Water decontamination cycle technique in a kind of modification regeneration plastics-production, comprises following processing step,
1) according to needs of production, the suitable filtering basin of area, settling tank, water reservoir are set, the waste water (as rinse water) producing in producing is introduced to filtering basin by pipeline;
2) in filtering basin, put into appropriate precipitation agent, the foreign material in water are precipitated, and make water in filtering basin, leave standstill for some time;
3) precipitation process is put into water precipitated metal pond again after completing, and throws in alkali and polyacrylamide in precipitated metal pond, allows waste water react;
4) after having reacted, by high-pressure pump, waste water is sent into plate-and-frame filter press, through plate-and-frame filter press, containing metal foreign material in waste water are filtered out, filtered water flows into water reservoir, and filter cake is for refining;
5) the pH value of test retaining pool inner water, and regulate pH value according to actual test result, after the adjusting of pH value is qualified, when needed, supplies with production unit by water pump and use.
A kind of modification regeneration plastics integrated energy-saving complete processing, comprises following processing step,
1) used and scrapped battery is carried out to cutting process, then the plastic component containing in used and scrapped battery, grid, lead plaster, lead powder etc. are separated in succession;
2) plastic component of separating is put into cleaning equipment and clean, after having cleaned, drain the water and send into sterilization equipment disinfection;
3) plastic component after sterilization is sent into pulverizer and is ground into particle, then plastic grain is put in forcing machine quantitatively, according to prepared product need to add again other batchings, extrude through forcing machine;
4) plastic strip that forcing machine is extruded directly enters into forming mould, directly obtains finished product after the demoulding, and finished product is carried out after surface treatment.
The invention has the beneficial effects as follows: the present invention can carry out collection and purification recycling by the sewage of discharging in producing; make sewage aborning reach zero release, effectively protection of the environment, has saved resource; reduce production costs, reached the doulbe-sides' victory of protection of the environment and company interest.
Embodiment
For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
Embodiment 1:
Water decontamination cycle technique in a kind of modification regeneration plastics-production, comprises following processing step,
