Description
【Technical field】
The present invention relates to the technical field of Architectural Equipment, particularly a kind of conveyer belt automatic charging uniform discharge cement mixing
The technical field of machine.
【Background technology】
China along with urbanization process quickening, the construction of infrastructure also few, from house to road and bridge,
It is required for using cement, cement is powdery hydraulicity inorganic coagulation material.Add water stirring after into slurry, can harden in atmosphere or
Person is preferably hardened in water, and can the materials such as sand, stone is cemented together securely, the mixture of early stage Calx and volcanic ash
Much like with modern lime pozzolanic cement, with its concrete made by cementing rubble, not only intensity is higher after hardening, and
The erosion of fresh water or brackish water can also be resisted.For a long time, it is used as a kind of important Binder Materials, 1756, Britain's engineering
Teacher J. Si meter Dun have found when the characteristic that some Calx are hardened in water is studied：Obtain hydraulic lime, it is necessary to adopt and contain
The limestone of clay is firing；For the masonry mortar of submerged structure, optimal composition is by hydraulic lime and volcanic ash
It is made into.Theoretical basiss have been established in this important development and development for being found to be modern age cement.1796, British J. Parkers used
Marl has burnt out a kind of cement, and outward appearance is in brown, and the Calx and volcanic ash mixture like ancient rome era is named as sieve
Horse cement.Because it is to make raw material using natural marl, directly fire without dispensing, therefore also known as Parker's cement.Tool
There are the good hydraulicity and soon solidifying characteristic, be particularly well-suited to the engineering contacted with water.1813, the civil engineer Bi Jiafa of France
Calx and clay are showed best by three to one cement performances being mixed.1824, English architecture workman Joseph A Si
Spectrum fourth has been invented cement and has achieved the patent right of Portland cement.He is raw material with limestone and clay, is matched somebody with somebody by a certain percentage
After conjunction, the mature calcined material in the shaft kiln similar to burnt lime, then Jing is levigate makes cement.Because of color and English after hardening of cement
Portland place is similar for the stone of building on Glan island, is named as Portland cement.It has excellent building performance,
It is with historically new significance in cement history.1907, France's ratio angstrom replaced clay, mixed limestone using the red bauxite of aluminum ore
It has been fired into cement.Because this cement contains substantial amounts of aluminium oxide, so being called " alumina cement ".1871, Japan started
Build cement plant.1877, the Crampton of Britain invented rotary furnace, and reforms into more preferable returning in Jing orchid Pehanorms in 1885
Converter.1893, Japan far rattan show row and loyal two Crinis Carbonisatus in inland sea three understood the portland cement for not being afraid of sea water.20th century, people
While Portland cement performance is updated, a collection of cement suitable for special construction project, such as high alumina have been succeeded in developing
Cement, special cement etc..Global cement type has developed to kind more than 100, about 2,000,000,000 tons of cement annual production in 2007.China
First national unified standard has been worked out in nineteen fifty-two, manufacture of cement has been determined with multi items multiaspect as principle, and by Portland
Essential mineral composition of the cement as contained by it renames as silicate cement, renames as portland cement so far again afterwards.2012, in
State's cement output reaches 21.84 hundred million tons, and yield accounts for the whole world more than 50%, cement mixer also known as concrete mixer, be for
Cement, sandstone aggregate and water are mixed simultaneously machinery of the mixing into concrete mixture.Existing cement mixer mainly by mix cylinder,
The composition such as charging and shedding mechanism, water system, prime mover, drive mechanism, frame and supporting arrangement, falls certainly by stirring theory point
Formula and forced action type；By the fixed and movable type of mounting means point；By discharge method point tilt bed and non-tilt bed；By mixing barrel structure
Form point pears formula, drum, bipyramid, disk vertical shaft type and circular groove axle horizontal type etc..
Existing blender can make cement drop on ground during discharging, usually, uneven mainly due to discharging,
Discharge when expecting in agitator many, discharging is few when expecting few in agitator, and concrete grey and sandstone are needed in the blender course of work more
Etc. different raw materials, manpower is needed in charging process using utility cart feeding, the artificial working strength of increasing, market demand one
Plant blender, it is desirable to be able to make blender discharge uniform, reduce cement and waste, the efficiency for discharging is improved, while feeding automatization
Degree is high, can substantially reduce artificial labor intensity.
