For achieving the above object, the utility model provides following technical scheme: a kind of building block type plastic drying system, comprise dehumidifying heat pump and some driers, also comprise firing equipment, the air outlet of described firing equipment connects the air inlet of each drier by multiple air intake lateral correspondence, the air outlet of described drier connects the return air inlet of described dehumidifying heat pump by each return air lateral; Control valve is equipped with on described each air intake lateral He on described each return air lateral;
Described firing equipment comprises heater and the back-up heater of independent operating.
By adopting technique scheme, the air outlet of drier connects the return air inlet of described dehumidifying heat pump by each return air lateral, reach gas in drier to be dehumidified by air outlet arrival dehumidifying heat pump, carry out adding the complete loop of thermosetting one entering firing equipment, the air heat treatment of again entering firing equipment adds carries wet ability, just can avoid air-flow back-mixing, even if it is good in drier to be that small lot resin also can reach drying effect, residual moisture controls within 0.02%.
Being provided with some driers can the different types of plastic pellet of continuous drying in batches, heater and back-up heater can independent operatings, reaching can the object of independent temperature control, when multiple drier opened by needs, back-up heater can be opened, reach and multiple drier is carried, increase dry efficiency.
Further, described drier comprises staving, is provided with at least one place support in described staving, described support has the screen cloth placing dry resin, and the aperture of described screen cloth is less than the particle diameter of band dry resin.
Further, described screen cloth is barrel-like structure, and described screen cloth and support removably connect.
Pass through technique scheme, first material consumption is on demand loaded in corresponding screen cloth, drying is carried out to the material in this drier, after drying, screen cloth is proposed in staving together with material, convenient to use, and be provided with at least one place support and can realize that there are corresponding multiple screen clothes, can carry out the drying of the resin particle of different batches again in same drier, and the particle diameter that the aperture of filter screen is less than band dry resin can realize not spilling from filter screen.
