Description
Technical field
The invention belongs to and solid waste is changed into useful or harmless material, be specifically related to a kind of building waste and process equipment.
Background technology
Quickening along with urbanization process, urban construction, reconstruction of the old city town create substantial amounts of building waste, the quantity of building waste has accounted for the 30～40% of municipal refuse total amount, wherein, overwhelming majority building waste is unprocessed, just transported to countryside or rural area by unit in charge of construction, air storage or landfill, consume substantial amounts of land acquisition expense, refuse collection expense etc., take a large amount of soil, form rubbish and enclose the phenomenon in village, besieged city, have a strong impact on town and country image, then cause huge environmental problem, economic problems even social problem.On the other hand, china natural resources problem is day by day serious, and the natural aggregate of high-quality has become exhausted in some place, and the qualified concrete gravel in many places is in rather short supply, causes the cost of architectural engineering to increase, Quality Down.Simultaneously because cut into a mountain for quarrying on a large scale, destroy natural landscape and ecological environment, the significant departure strategy of sustainable development of China's economy and environment.In this case; the work of building waste circular regeneration is combined with the production of economic materials for wall; building sand is produced with building waste; both dissolved the building waste that cannot process in a large number; the problem solving again resource rational utilization; the level of resources utilization can be effectively improved, protecting ecology and promoting economic development.
Currently also having the equipment that building waste is processed, generally comprise disintegrating apparatus and screening plant, process technique imperfection, the regeneration aggregate granularity after big multiprocessing is uneven, and range of application is restricted.And owing to building waste containing substantial amounts of metal class, bamboo wood class and Plastic foreign material, wherein bamboo wood class and Plastic foreign material are blended in regeneration aggregate with building waste, the intensity of load-bearing class building material can be reduced, and metal class foreign material are generally difficult to broken, staying easy occluding device in processing, the equipment that affects normally uses.
Metal class foreign material are generally adopted concentration equipment to be easily separated by the process equipment of existing building rubbish；Bamboo wood class and Plastic foreign material are not generally sorted or adopts the mode of manual sorting, also have and adopt air-feeding type sorting equipment to process, such as " name is called: light material separating device; application number is: Chinese patent 200520125092.2 ", this invention is a kind of light material separating device, particularly domestic waste material separation device.It includes the casing with charging aperture and waste port, and chassis sidewall has air inlet upwards, and the position of light material outlet is higher than air inlet.The present invention has simple in construction, feature with low cost, and the lightweight object such as paper, plastics can be effectively taking place with sandy soil, metal etc. and separate by it, is particularly well-suited to the separating treatment to municipal refuse.Adopting air-feeding type sorting equipment, to consume the energy on the one hand, on the other hand, it is just big that building waste processes the original dust in place, adds blower fan, and the healthy of staff can be impacted by dust.
Summary of the invention
For overcoming the deficiencies in the prior art, it is desirable to provide a kind of equipment possessing the building waste production brickmaking sand separating light material, this device structure is simple, with low cost, the light materials such as bamboo art, plastics can be easily separated, improve the quality of regeneration aggregate, use the present invention that building waste is processed, remove light refuse therein, produce qualified construction garbage brick sand.
