Description

A kind of air blast drum-type fine aggregate screening plant
Technical field
The present invention relates to Supplying Sieving Mechanisms, and in particular to a kind of air blast drum-type fine aggregate screening plant.
Background technique
Asphalt concrete pavement is most common road surface form.When producing bituminous concrete, it is necessary first to grain Diameter is non-uniform to gather materials and is sieved, and is then gathered materials with what is be sieving through, carries out ingredient according to a certain percentage.General screening plant For oscillatory type, each layer sieve is stacked up and down.Aggregate particle passes through each layer sieve under gravity during vibration, completes Screening.However, 1mm fine aggregate below is lighter, it is affected by gravity smaller, is difficult through sieve, thus screening efficiency is very low.It is real Border sieve when find, big partial size gather materials screening complete when, small particle gather materials screening also do not complete.Therefore it needs to gather materials with small particle The screening deadline controls sieving time, and the time is longer, and screening efficiency is lower.Long-time vibrosieve is possible to will cause big Partial size aggregate crusher destroys original particle composition ratio.On the other hand, 1mm fine aggregate below is readily suspended in vibration In air, air is not only polluted, but also can seriously damage staff's health.Some researches show that the works in dust atmosphere for a long time Work can injure lung, and pneumoconiosis etc. is caused when serious.In addition, vibrating screening separating device noise is big, noise pollution will cause.
Summary of the invention
The present invention is low in order to solve existing Vibration Screen component efficiency, and noise is big, heavy-polluted problem, and then proposes one kind Air blast drum-type fine aggregate screening plant.
The technical solution adopted by the present invention to solve the above technical problem is:
A kind of air blast drum-type fine aggregate screening plant includes sifting barrel, blower, motor, Rose Box and transmission mechanism, sieve Point cylinder is horizontally disposed, and motor is turned round in the axial direction by transmission mechanism drive sifting barrel, the arrival end of sifting barrel and blower Air outlet connection, the outlet end of sifting barrel is connect with Rose Box.
The beneficial effects of the present invention over the prior art is:
1, the present invention makes full use of the characteristics of light-weight fine aggregate, easy suspension, is sieved by the way of air blast, can Efficient to sieve fine aggregate, fine aggregate is successively sieved by sifting barrel in the present invention, fine aggregate is once sieved, work It can be improved 70% or more as efficiency.
2, baffle is arranged in the present invention on screen drum, and baffle drives fine aggregate movement, fine aggregate movement during rolling It is fallen when above to screen drum, so that fine aggregate is more abundant with screen contact.
3, the present invention replaces traditional vibration-type screening using roller screening, hence it is evident that reduces noise pollution.
4, setting Rose Box is filtered to by the air-flow of sifting barrel in the present invention, is adsorbed dust particles therein, is kept away Exempt to pollute air.
