Description

A kind of concrete high-speed stirring apparatus

Technical field

This utility model belongs to concrete batch plant field and in particular to a kind of concrete high-speed stirring apparatus.

Background technology

With social development, the reason such as old building is aging with age, natural disaster or policy planning is damaged, and stays big The waste and old construction material of amount, wherein most is concrete, and the continuous generation of new building needs substantial amounts of building mixing Material, in order that these waste and old concretes obtain utilization again, people employ the regeneration techniques of construction waste, generally by old material As dispensing, directly ginseng is joined, and some add supplementary part virgin material again, forms regenerating mixture, and these new compounds and regeneration are mixed Close material can as the stock of concrete (bituminous concrete and cement concrete) in building industry as main Building wood Material is extensively applied.Cement concrete, generally with cement as cementing material, the raw materials such as sandstone, Calx, cinder is carried out mix and blend, Finally it is fabricated to concrete, put into the construction projects such as house, road.Bituminous concrete generally has a deciding grade and level combo by apolegamy The mineral aggregate becoming, is controlled strict with a certain proportion of bitumen for road use material including rubble, grating gravel, aggregate chips or sand, breeze etc. Under the conditions of mixing form.

During concrete production, it is required for carrying out mix and blend to dispensing, to ensure each component, uniformly ginseng is joined.At present Concrete central mix plant is divided into forced action type stirring and gravity type stirring by its alr mode, and the stirring theory of gravity type is: when stirring When mixing cylinder rotation, rely on the fixing blade being arranged in cylinder to drive each composition material to rise to the certain eminence of diameter of cylinder, borrow Gravity makes material fall, and is distributed in the material of different parts in cylinder, because its granule is different, the time of whereabouts, drop point and rolling Dynamic distance is different, and so that material phase IPN is pitched, turn, mix to reach diffusion uniformly.The groundwork of forced mixer Part is a disk, in disk built with some radially distributed stirring vanes, during disc rotary, be in different angles and When the blade of position passes through the bed of material, overcome material inertia force, frictional force and viscosity resistance make material produce ring, radially and Vertical motion, thus produce stirring action；Gravity type agitating device mainly stirs liquid concrete.

Concrete is important construction material, and fresh concrete quality is the most basic of the agitating device performance to blender Requirement, be also primary performance requirement.With above-mentioned two class blender ready-mixed concretes, typically just can reach within a short period of time Macroscopically uniform, but the quality of these compounds is all difficult to reach the higher prescription of concrete, therefore, thing to be increased Expect intergranular collision frequency and phase mutual friction, improve the quality of concrete it is necessary to improve the rotating speed of agitating device.Forced action type Agitating device is the main flow that domestic and international mixing plant uses, and it can stir multiple coagulations such as mobility, half dry and dry Soil；Forced action type agitating device is divided into main shaft planet stirring device, single horizontal axis agitating device and Double-horizontal-shaft stirring dress by version Put, these existing concrete central mix plants are under the relatively slow-speed of revolution and are stirred it is impossible to efficient ginseng combo of realizing divides mixing equal Homogenize；Even if some agitating devices employ high-speed stirred, in whipping process, the stirring vane of high-speed rotation rotates and makes material Centrifugal force increases, and also easily smashes aggregate, thus change original level joining, so that material is isolated, causing the concrete after stirring Expected effect can not be obtained.
