Description

Mixing plant
Technical field
The utility model relates to a kind of mixing plant.
Background technology
After the nineties, along with the fast development of China of world economy especially housing construction, commerical ready-mixed concrete demand increases, concrete mixing plant also obtains high speed development, at present, China every year completion floor space greatly about 2,000,000,000 square meter, existing building storage 40,000,000,000 square metres, building energy consumption reaches 1.2 trillion degree of electricity and 4.1 hundred million tons of standard coals every year, adds the energy consumption in production of construction materials process, accounts for 46.7% of whole society's energy consumption.The a large amount of energy consumption of building construction forces the mode of production and the growth pattern of the dwelling construction of people's re-examine.
In recent years, explain and publicise by persistence through relevant department, relevant enterprise and expert, explore, put into practice, people have had further understanding to housing industrialization, after particularly country proposes the target of development housing and public buildings that use less energy and land, accelerate to promote that housing industrialization is very urgent, extremely urgent.Housing industry is the important symbol of modernization of the housing industry, refers to the house mode of production (or technological means).Be use the tissue of modern industrialization and the means of production, to each production factors in each stage of the overall process that house is produced by Integration ofTechnology and system combination, reach architectural design standard, component production plant, house components seriation, site operation assemblingization, the integration of structure finishing, production and operation socialization, forms orderly batch production continuous-flow type operation, thus reaches raising quality, raise the efficiency, improve the life-span, reduce costs, reduce energy consumption.
PC (Prefabricated Concrete Structure) i.e. " prefabricated assembled concrete structure ", is take precast concrete as main member, through assembling, connect, bound fraction cast-in-place and formed xoncrete structure.PC component is the finished product concrete component making with the batch production of component process unit and formed.
Along with people are to the continuous pursuit of housing quality, house is from function of substantially living, be developed to the comfortable of external environment, arrive the raising of inherent inhabitation performance quality again, all require to implement housing industrialization, and the inexorable trend of PC housing industrialization China Real Estate industry development especially, in recent years, housing industrialization, energy-saving and emission-reduction, quality safety, all building new concepts such as ecological, environmental protective are that PC component brings development opportunity, a large amount of infrastructure constructions in Development of China's Urbanization, extensive guarantee house is badly in need of standardization, fast construction high-quality house, more PC component provides broad space.
Develop PC component, just need the mixing plant mated with it to provide concrete to it, there is following limitation in traditional Of Concrete Mixing Station in layout type:
Its floor space of traditional commodities concrete mixing plant is larger, mixing plant needs to arrange that sandstone stock ground is used for stacking sandstone, after the sandstone that sand-transport truck ships is discharged into sandstone stock ground, mixing plant needs to need loading machine to mixing plant proportioning station material loading during sandstone, material repeatedly transports wasting manpower and material resources on the one hand, a large amount of dust polluting environment is produced on the other hand in the process of transfer, also to reserve powder skip car and loading machine passage around mixing plant simultaneously, land occupation resource is many, does not meet the developing direction that national environmental protection is energy-conservation;
Its floor space of traditional commodities concrete mixing plant is comparatively large, also will reserve powder skip car and loading machine passage around mixing plant, and mixing plant is away from the factory building producing prefabricated component and factory, and inconvenient batch production unified management, is not suitable for precast concrete Production requirement;
Its environmental-protecting performance of traditional commodities concrete mixing plant is not high, and the dust, noise, sewage etc. of mixing plant affect the production of factory or factory, do not meet the developing direction that national environmental protection is energy-conservation, are also not suitable for precast concrete Production requirement;
Traditional commodities concrete mixing plant feed opening is away from factory building or factory, and concrete transportation is inconvenient, is not generally arranged in factory building feature that is inner or factory building edge for prefabricated production line and carries out layout, be not suitable for precast concrete Production requirement;
Traditional mixing plant is because being originally conduct oneself with dignity that comparatively large (a general mixing plant gross weight own is at about 100 tons, add the material of storage, overall weight is more than 200 tons), tradition mixing plant needs corresponding concrete foundation to carry out load-bearing, concrete foundation generally needs at ground excavation certain depth, and concrete soil mixing station General Requirements is near factory building or factory, or be directly positioned over factory building or inside plants, because factory building inner width is limited, and factory building internal support post itself has basis, if at factory building foundation side excavation pit again, can produce to cause to factory building original base and cave in, the adverse effects such as underlying strength reduction, secondly lower aquaporin is generally furnished with near factory building, electric wire irrigation canals and ditches etc., if this just causes the limited of mixing plant foundation excavation, therefore the mixing plant on traditional band basis is very limited in precast concrete is produced.
Therefore, urgently provide a kind of mixing plant, be specially adapted for producing precast concrete.
