Description

Building decoration garbage co-processing technology without manual sorting

Technical Field

The invention relates to a production process for cleaning, crushing and classifying building decoration garbage and building demolition garbage with complex components on the premise of not carrying out manual sorting.

Background

At present, with the industrial development of China, the application of various decoration garbage crushing treatment technologies is becoming wide, and the design of various treatment processes is gradually increased. In the traditional decoration garbage crushing treatment process, more manual sorting and simple screening are applied, and few dry type fixed crushing processes and dry type movable crushing processes are used. Especially when the classification work of decoration garbage is poor, most decoration garbage crushing production lines cannot effectively separate soil and aggregate completely, so that the strength of concrete or recycled products prepared by recycled aggregate is low, and the use requirements cannot be met.

At present, decoration garbage in China generally has no effective classification work, and various materials are often mixed in the decoration garbage, so that higher design requirements are provided for a treatment production line. If the soil cannot be effectively separated and other light impurities of materials are sorted out, the produced product cannot be sold as a finished product. Therefore, simple and effective sorting technology is an important problem which cannot be avoided and ignored when the decoration garbage is treated.

In various technologies for regenerating concrete aggregate from decoration garbage, the aim is to achieve high cleanness and good particle shape of the regenerated aggregate. Many manufacturers specially set aggregate shaping workshops and equipment, mechanically grind crushed recycled aggregate, and completely grind water caltrops of the recycled aggregate and cement stones wrapped on the aggregate, so as to obtain recycled aggregate with better grain shapes and differential products. The applicant previously filed an invention patent named 'recycled concrete aggregate shaping technology' and granted, but the technical scheme of the invention cannot solve the problem of treatment of decoration garbage, so that a new improvement is made on the original basis to realize the cooperative treatment of the decoration garbage.

Therefore, the decoration garbage crushing treatment industry in China still lacks a production line technology which is energy-saving, low-consumption, high-efficiency and simple. In the prior art, when decoration garbage is treated, almost 100% of the decoration garbage needs to be sorted by manual classification by manpower or robots, so that the production efficiency is low, the product quality is poor, the operation cost is high, the industrial treatment of the decoration garbage is difficult to realize all the time, and the survival and development of the whole industry are influenced.

The applicant has also previously thought that the treatment of furnishing and furnishing waste must first be sorted manually and applied for the application number on 1/2022: 2022100000472 patent application entitled "a cooperative processing technique of decoration garbage and building demolition garbage". However, through repeated design comparison, the applicant finds a simpler, more effective and more efficient processing method, can avoid the link of manual sorting and completely realize automatic sorting, so that the method is innovated again on the basis of the previous application, and the patent is immediately applied again.

Meanwhile, the initially broken construction demolition waste is sent into the roller stone washer 2, large concrete or brick and tile waste in the construction demolition waste is used as steel balls, and water is added to impact, grind and clean brick soil and light and heavy impurities of the decoration waste. The gypsum board, the kitchen garbage, the grass and wood paper and other fragile substances in the decoration garbage are smashed into slurry, other light and heavy substances are cleaned, mud and fine aggregate in the mixture are screened out by utilizing the roller screen 3 integrated with the roller stone washer 2 or split, the residual light impurities and the materials to be crushed are continuously added with clear water in the roller screen to be washed until the materials do not contain a piece of soil, the light substances such as plastics, foams, cloth and other combustible light substances fall into the winnowing machine 4 to be blown out, and the light substances such as wood, rubber, aerated blocks and the like fall into the flotation machine 5 to be floated.

After iron and steel substances such as the floated concrete blocks, tiles, stones and the like are separated out through the iron remover 6, the steel and iron substances are sent to the screening equipment 7, qualified coarse aggregate is screened out, large super-grain aggregate is sent to the main crusher 8 to be crushed, the crushed aggregate is conveyed through the belt conveyor and enters the roller stone washer 2 again to be impacted, ground, cleaned and shaped, then slurry and fine aggregate are screened out through the roller screen 3, light impurities in the mixture are separated out through the air separator 4 and the flotation machine 5, the separated iron and steel substances after secondary crushing are separated out through the iron remover 6, and the mixed aggregate is sent to the screening equipment 7 through the belt conveyor to be screened out to obtain a qualified coarse aggregate finished product.

The crushing process is firstly proposed, decoration garbage and building demolition garbage are directly subjected to cooperative treatment without manual sorting, the sorting efficiency can be greatly improved, and the quality of sorted products is improved. When fitment rubbish is dealt with production, all rubbish in the fitment rubbish is whole to be sent into shredder 1 and is torn the piece in unison, then unified entering cylinder stone scrubber 2 is handled, rely on the building that gets into cylinder stone scrubber 2 simultaneously to demolish the big stone in the rubbish, carry out violent impact grinding to thistle board in the fitment rubbish, waste paper, rubbish from cooking, earth, rotten leaf of dry branches, rotten rubbish, add gas block etc. utilize big stone to act as the steel ball, smash into mud with these fragile material, it becomes regeneration soil at last to mix into mud.

Light materials such as plastics, rubber, wood and the like which cannot be smashed are screened out cleanly, and can be separated out through winnowing and flotation for recycling. Simultaneously because the mode that utilizes to grind to wash has got rid of the earth dust etc. that glues on plastics and wood, has avoided the raise dust pollution problem in traditional selection by winnowing mode, has improved the cleanliness factor of regeneration product simultaneously again, has produced the regeneration product that more does benefit to the resourceization, the added value is higher.

The treatment process can avoid dependence on a large amount of manpower on the decoration garbage sorting platform, improves sorting efficiency and reduces labor cost. Meanwhile, any other secondary garbage needing to be buried is not produced, so that the environmental protection cost can be saved, and the method has important significance for 'solid waste recycling' and 'garbage enclosing city' prevention.
