Description

A kind of novel energy-saving environment-friendly sandstone screening installation
Technical field
The present invention relates to construction machinery equipment technical field, specially a kind of novel energy-saving environment-friendly sandstone screening installation.
Background technology
Construction industry is a national pillar industry, and Chinese construction industry largely solves the problem of employment, meanwhile, The growth of the construction industry GDP national to one, which increases, also to play an important role.Development of Urbanization promotes infrastructure construction.I The population that state there are about 1% every year enters cities and towns, urban population increase about 20,000,000 every year from rural area, it is contemplated that the year two thousand thirty total people of China Mouth is by 1,500,000,000, and the population in cities and towns is up to 9.7 hundred million or so, close to double.Urbanization brings development of real estate and city base Infrastructure construction demand will persistently increase.China's Urban House will also meet in addition to the demand in face of increasing urban population newly There is very big development & construction potentiality in the great demand that the residential building to have arrived updates, dwelling construction market.State at present Interior city function, which is distinguished, has certain defect, and city makes every effort to accomplish that land values maximize in terms of plan for land, thus must Existing urban function region, including the palpus re-optimization configuration of the necessary resources such as house, communal facility are so planned again, especially Real estate industry will face the general layout reshuffled.But for current city planning design, Real estate industry at least exists Subversiveness change will not be undergone in quite a long time, but continues to the situation of steady development, this also builds drive Industry is built towards energy-conserving and environment-protective, intelligent direction to develop.
In general proportion of the construction material in whole building construction costs is about 60%~70%, and construction industry is In flourishing, such as 2014, national total output of building industry was 15,931,300,000,000 yuan, increases by 16.1% on a year-on-year basis;National construction industry room Construction area in room is 11,300,000,000 square metres, increases by 14.6% on a year-on-year basis, speedup persistently slowed down compared with 2012.Building Trade in China exists After development speedup in 2003 is more than 20%, rapid growth is kept for many years, but 2012 start to go down hill, speedup innovation in 2014 It is low.Construction industry development and the investment demand of one of the national economic development " carriage drawn by a team of three horses " are closely related.2014, national fixed assets Production investment is without 43,652,800,000,000 yuan of peasant household, and the actual growth by 19.2% of 19.6% deduction price factor was increased in name than 2012. This is also that since two thousand three, annual investment in fixed assets name speedup drops to less than 20% first.
It is 0. 07 four to two that sandstone, which are referred to after rock decay through rain drop erosion or the particle diameter formed by rock rolling, Pellet between hair, its Main Ingredients and Appearance are silica, and sandstone are a kind of common building materials, its mainly by and cement Mixing, concrete is formed, during just being excavated due to sandstone, its granular size is different, therefore before being mixed with cement, Need to sieve sand, to ensure that the particle of the mixed sandstone overwhelming majority meets that mixing requires.
At present, artificial sandstone screen universal one screen cloth of use and are supported in ground, and people is taken using spade to sieve, this planting sand The labor intensity of stone screening mode worker is big, and worker feels fatigue after a period of time is screened, and existing aggregate sieve chooses to install Put, structure is complex, is not easy to operate, and screening effect is general, in machine operation, easily forms significant shock, unfavorable Worked for a long time in machine, easily cause the damage of machine.
