常熟市福新包装容器有限公司Changshu Fuxin Packaging Container Co. LTD
Process flow description:
The iron drum entering the production line is first processed in the early stage, and then entered the production line for processing. After processing, it is later assembled. After assembly, it is painted and dried, and the finished product is obtained after passing inspection.
① Pre-treatment
The old iron drums will be classified and screened, and then the old iron drums that can be refurbished will be pre-processed. First, the cover will be dropped, and then the residual materials in the barrel body will be cleaned by horizontal scraping equipment or vertical cleaning equipment. Pour the residual liquid from the waste packaging barrel into a special residual liquid collection barrel, and the solid waste generated is S1. Exhaust gas G1 is produced in the process of cover dropping and residual cleaning.
② Automated production line
A. Heat and polish
Use diesel fuel as fuel and heat the residual material in the iron drum. Deformation, metal iron drum in order to ensure performance doesn't change, then control the flame is not direct contact with the iron drum wall, in order to avoid burning, only to heat the iron drum and stripping scrap and under 200 ℃, the temperature control loop through four station heating, grinding, heating 6-10 s, every time will be scrap bucket curing processing, finally remove residues in barrels. The exhaust gas G1 is produced in the heating and grinding process.
B. to take off the lacquer
The paint removal is shot blasting, and the paint removal treatment is carried out on the outside surface of the iron drum, so that the surface finish is uniform, the iron drum is not easy to rust, and the processing quality and service life of the iron drum are improved. Exhaust gas G1 and solid waste S2 are produced in the process of paint removal.
C. plastic
Rounding the defects such as the concave and convex of the iron drum, the iron drum can meet the requirements of the roundness of the new drum after being reshaped.
D. Polishing rinse
Use the brush to brush the residue on the inner wall of the bucket, and then soak the bucket upside down in the antirust liquid water tank to remove the residue on the inner wall of the bucket. The exhaust gas G1 is produced during the polishing and washing process.
E. Rustproof drying
The inner wall of the iron drum is treated with antirust liquid, and dried with gas pipeline, and then dried with high-frequency equipment. Waste gas G1 is produced in the process of rust prevention and drying.
F. Treatment of drum cover
The barrel cover treatment includes the heating and grinding of the barrel cover and the paint removal of the barrel cover. The paint removal of the barrel cover is carried out to remove the residues in order to meet the requirements of the later treatment. The waste gas G1 is produced during the treatment of the barrel cover.
③ Post-processing
Processing including the barrel of the processing and steel drum assembly processing, barrel processing including the cap, plastic injection and baking, barrel cover order cover equipment, its purpose is to will build for plastic barrels, reached the requirements of assembly, injecting device and barrel cover cover the same type of equipment, its purpose is to ensure that the lid and body assembly after sealing, barrel cover baking equipment USES a multi-layer barrel cover baking box, The purpose is to dry the glue filling place of the barrel cover. Iron drum assembly adopts single position assembly equipment, its role is to combine the barrel body and the barrel cover as one, the leak testing device adopts leak testing equipment, the purpose is to check the tightness of the iron drum, to ensure the quality of the iron drum. The exhaust gas G1 is produced in the process of drying and leakage testing. Defects S5, whose solid waste is iron drum, are produced in the process of leak testing.
(4) painting, drying: this section is set up a water curtain type painting room. The packaging barrel that needs to be painted is hung on the shelf in the barrel area, and enters the painting area from the side of the painting room through the chain. The water-based paint is dispersed into uniform and fine fog drops with the help of air pressure through the spray gun and applied on the surface of the product. After the painting is finished, it exits the painting area from the side and enters the drying area through the transport device.
There is no special paint mixing room for this project. The purchased finished water-based paint has been prepared, and it can be used for spraying after adding a small amount of water to mix. Water-based paint is mixed with water in a mixing tank. The spray gun is soaked and cleaned regularly with solvent (xylene), and the waste solvent after cleaning can be recycled in the cleaning process of the inner wall of the packaging barrel.
The tail gas produced in the spray painting stage is collected by the water curtain to collect water-based paint particles, and then emptied after being treated by the activated carbon adsorption device. The paint residue collected by the spray painting of the water curtain is sent to qualified units for disposal as hazardous waste.
After spraying the paint, it enters the tunnel drying chamber, and uses hot air (diesel heating) as heat carrier for direct heating to dry the coating on the barrel body. The exhaust gas G1 and solid waste S2 are produced in the process of painting drying.
⑤ inspection: appearance inspection after qualified, as a finished product storage.
It can be seen that the automatic 200L iron drum cycle renovation and transformation process does not use solvent, which greatly reduces the amount of solvent and the production of "three wastes"; Thoroughly clean up the residual liquid in the barrel and remove the residue in the gap of the barrel. The steel barrel can be completely restored through shaping, reaching the quality standard of the new barrel. Compared with the enterprises manufacturing new barrels, the recycling barrels of this project have a lower cost and obvious competitive advantage, which can bring economic benefits to the enterprise.
The automatic 200L iron drum cycle renovation and transformation process is suitable for the treatment of waste packaging drums containing dye coating waste, organic resin waste, ether-containing waste and waste organic solvents.
Process flow description:
(1) Dump residual: recycle the residual liquid in the bucket, check whether there is any residual material in the bucket, and use the dumping machine and vacuum suction equipment to recycle the residue. Waste gas G2 and solid waste S1 are produced in the process of decomposing.
(2) shaping: using automatic compressed air shaping machine to repair the deformation of the recycling barrel.
(3) cleaning: according to the material situation in the bucket, choose to add xylene or ethyl acetate to the bucket for cleaning, and then pour out, the whole process is carried out in the eight-station automatic cleaning machine. The cleaning solvent on the inner wall is recycled and used. A filter screen is set in the circulating tank to discharge the filtration waste residue regularly and add fresh solvent to the circulating tank. It should be replaced once a week. The waste gas G2 and solid waste S3 are produced in the cleaning process.
(4) spray painting, drying: water-based paint through the spray gun with the help of air pressure, dispersed into uniform and fine fog drops, coated on the surface of the product. After spraying the paint, it enters the tunnel drying chamber, and uses hot air (diesel heating) as heat carrier for direct heating to dry the coating on the barrel body. The exhaust gas G1 is produced in the process of painting and drying.
