Description
Technical field
The utility model relates to a kind of equipment for preparing bituminous concrete, especially a kind of microwave prepares bituminous concrete
Equipment belongs to bituminous concrete preparation technical field.
Background technique
The preparation process of existing bituminous concrete can be divided into heat and mix and stir two kinds of cold mixing.The capital equipment packet of pitch batching plant
It includes:Asphalt heating pot, sandstone storage, mineral powder bin, heating roller, mixer and weighing equipment, steam boiler, bitumenpump and pipe
Road, dust removal installation etc., there are also sub-sieves again and bunkerage that heat is gathered materials for some.
In preparation process, mostly used after first heating sand material drying in the past, then mixed and stirred with heated bitumen and cold miberal powder；
Later again developed it is a kind of first with heated bitumen mixed it is wet gather materials, then reheat the method mixed thoroughly, with eliminate because gather materials heating with
Flying dust when drying.When using latter technique, to prevent the moisture remained in mixture from influencing bituminous concrete service life,
Asphalt anti-stripping agent is used, simultaneously preferably to enhance water resistant ability.
Which kind of ineffective technique, heating source are mainly that the fuel combustions such as diesel oil, gasoline, natural gas generate steam heating collection
Material and pitch,（It is unnecessary）The process of mixing and stirring takes a long time, and consuming energy and is easy to produce dust, and dust also needs special dedusting
It could be discharged after device processing.By the analysis to using energy source, evaporative removal has been used in compared with multiple-energy-source and has been gathered materials middle contained humidity
The step on.
Microwave is introduced into bituminous concrete field in 2000-2005, since absorption of the pitch to microwave is weaker, and gathers materials
In must containing high concentration inhale wave metal oxide can just be rapidly heated, so typically no directly carry out pitch coagulation with microwave
Soil preparation and production, existing microwave be mainly used in bituminous pavement reparation and regeneration, microwave road deicing, snow melting, can be again
The fields such as raw asphalt pavement material heating, the special quick heating gathered materials.
Summary of the invention
The goal of the invention of the utility model is：In view of the above problems, a kind of microwave is provided and prepares pitch coagulation
The equipment of soil, the utility model, which can be realized, prepares bituminous concrete by microwave.
The technical solution adopted in the utility model is as follows：
A kind of equipment that microwave prepares bituminous concrete has including the internal agitator tank with rabbling mechanism, inside and passes
