Description
Technical field
The utility model belongs to lost foam casting pipe fitting production technical field, is used more particularly to a kind of white die coating material drying
Hot-air system.
Background technology
, it is necessary to which EPS to be moulded to the shape for being made casting in vain in lost foam casting pipe fitting production technology, outer surface dip-coating applies
Material, then dries coating to form hard shell, is molded afterwards by burying case moulding pouring molten iron.
Existing white mould drying is all to use Boiler Steam radiator heating, drying room, is then dehumidified, dried using dehumidifier
Although temperature ensure that humidity is higher in dry chamber, white die coating material cannot be dried thoroughly, easily cause cast product stomata etc.
Defect.And the cast product stomata problem caused by Bai Mo drying is insufficient accounts for more than the 50% of substandard product sum.
The content of the invention
A kind of the shortcomings that the purpose of this utility model is to overcome prior art, there is provided white die coating material drying hot blast system
System, solves the insufficient technical problem for easily causing gradual gas hole defect of drying present in existing white mould drying course.
The utility model is achieved through the following technical solutions：
A kind of white die coating material drying hot-air system, it includes annealing furnace, ventilation duct and drying chamber, wherein：Around described
Heat exchanger tube is provided with outside the cooling section of annealing furnace, heat exchanger tube connects with the air inlet of ventilation duct, and the gas outlet of ventilation duct extends to
In drying chamber；High temperature draught fan is additionally provided with the middle part of the ventilation duct, the ventilation duct, which is provided with, matches somebody with somebody air valve, described to match somebody with somebody air-valve
Door is provided with temp.-control valve, the ventilation duct between high temperature draught fan and ventilation duct air inlet at the ventilation duct gas outlet
Gas outlet be connected with temp.-control valve air inlet, temp.-control valve gas outlet is connected with wind pipe.
Further, the drying chamber is provided with several, and ventilation duct runs through each drying chamber, and ventilation duct is in each drying chamber
Inside it is provided with gas outlet.
The waste heat of annealing furnace is utilized in the utility model, heat exchange pipeline is installed additional in annealing furnace cooling section, recycles high temperature to draw
In the white mould drying chamber that blower fan conveys hot blast；The offer of dry-heat air, it can be avoided while improving and drying indoor temperature
Drying indoor humidity is excessive, and the abundant drying of white mould surface coating material can be achieved.
Compared with prior art, the utility model has the advantages that production efficiency is high, cost is low, easily promotes.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in figure 1, a kind of white die coating material drying hot-air system, it includes annealing furnace 6, ventilation duct 8 and drying chamber 7,
Wherein：Heat exchanger tube 1 is provided with outside the cooling section of the annealing furnace 6, heat exchanger tube 1 connects with the air inlet of ventilation duct 8, ventilation
The gas outlet of pipe 8 is extended in drying chamber 7；The middle part of ventilation duct 8 is additionally provided with high temperature draught fan 3, is set on the ventilation duct 8
Have and match somebody with somebody air valve 2, described to be located at air valve 2 between high temperature draught fan 3 and the air inlet of ventilation duct 8, the gas outlet of ventilation duct 8
Place is provided with temp.-control valve 4, and the gas outlet of the ventilation duct 8 is connected with the air inlet of temp.-control valve 4, the connection of the gas outlet of temp.-control valve 4
There is wind pipe 5.
Further, the drying chamber 7 is provided with several, and ventilation duct 8 runs through each drying chamber 7, and ventilation duct 8 is in each baking
Gas outlet is provided with dry chamber 7.
The course of work of the present utility model is as follows：
First, start high temperature draught fan 3, by high temperature draught fan 3 by the temperature of heat exchange pipeline in the cooling section of annealing furnace 6 with
Hot blast form is delivered to ventilation duct 8, and is delivered to each drying chamber 7 by ventilation duct 8, according to the indoor temperature of each drying chamber 7
Regulation temp.-control valve 4 is controlled the air output of hot blast.
The essence that the utility model can be embodied without departing from invention in a variety of forms, it should therefore be appreciated that above-mentioned
Embodiment is not limited to foregoing details, and should widely be explained in claim limited range, therefore falls into right and want
Ask or the change in its equivalent scope and remodeling all should be claim and covered.
