How to test the selection and quality of automatic waste segregation system

In terms of recycling and utilization of municipal solid waste, especially in many aspects of paper, plastic, metal, wood, etc., including steel bars and gravel produced in the process of building demolition and decoration, they are all good recycled materials. It can be seen that the prospect of domestic waste treatment is still broad, and the application prospect of urban waste treatment equipment is very broad.

Only in terms of equipment configuration, it needs to be determined according to the type, composition, and difficulty of mixed treatment of domestic waste. As a whole, a domestic waste treatment equipment production line uses these equipment, such as bag breakers, shredders, sorting tables, conveyors, screening machines, magnetic separators, washing machines, dryers, etc., these equipment also There are some detailed classifications and models, which need to be determined according to the cost of materials.

And it is mainly for the classification of common garbage in daily life. If it is more complicated, photoelectric sorting equipment can be used, but compared with mechanical sorting and automatic control equipment, the cost is higher and the cost is higher. It also has a lot to do with customer needs and budgets. After all, if it is to classify domestic waste, first of all, it is necessary to clarify the composition of the waste, and make clear regulations on the sorting requirements, so that it is convenient to determine the configuration of automatic waste segregation system.

For the production quality of domestic waste treatment equipment, the large-scale waste treatment equipment after large-scale electric welding should be carefully inspected, and the factors causing defects should be found out and improved. Before the inspection, the large-scale garbage disposal equipment should be sandblasted or static milled to remove the solder and residues adhering to the surface of the large-scale garbage disposal equipment blades, and cleaned with rolling oil.
 
Check new items and regulations for domestic waste treatment equipment, check the structural compressive strength of all welds, use healthy powder and carbon-carbon composite grinding wheel to crush the shredder knife, the solder layer is thin and thick, and the thickness design scheme stipulates that it is 0.15mm . The basic bottom edge of the support point of the electric soldering iron head must not have air vents, lack of welding materials and other social problems. It is an important factor that the welding seam cannot exceed one seam length if the solder is not filled in the bulk garbage disposal equipment. If there are air vents, the bulky garbage The processing equipment will crack the entire blade of the weld.
Check the concave shape of the domestic waste treatment equipment. If the blade moves, the slack standard exceeds the technical standard, and electric welding should be carried out. Check the compressive strength of the electrode, use a hammer or copper hammer and the compressive strength of the blade to be moderate, or hit the compressive strength of the blade with a hammer to meet the standard requirements. It is not necessary to check the compressive strength of electric welding of blades. Plane dimension inspection of large garbage disposal equipment. If the blade has obvious dents, the blade is too hot and deformed. Boil a new blade before welding.
 
Check for cracks, the household waste treatment equipment has been cleaned with oil, and the blades are cracked. Oil seeps into the cracks, and black strips appear, which can be observed with the human eye or with a high magnification of 10-40 times. Look at the leaf cracks, and you can also choose based on the color. Soak some cutting edges of special tools for large-scale waste treatment equipment in saturated solution for 10 to 15 minutes, then pick them up with cold water, cover them with a layer of clay, dry them in the sun, and observe the surface morphology. The color degree of the saturated solution of the equipment appears on the clay itself, which can be seen by the human eye. The gap in the middle of the large-scale waste treatment equipment cannot be reasonably applied, and it is required to re-design the welding seam
