Description

A kind of hot air drying box
Technical field
The utility model is related to a kind of hot air drying box, the pre-treatment being mainly used in aluminium roller coating production.
Background technology
Traditional hot air drying box installs heat-generating pipe in the case, achievees the purpose that dry aluminium sheet by electrically heated mode. The high energy consumption of this hot drying box, heat-generating pipe are easily burnt out, and production line is caused to stop transport, influences production efficiency.
Utility model content
The utility model in view of the above problems, provides a kind of hot air drying box, solves high energy consumption, equipment work Unstable the problem of production line is caused to be stopped transport.
The utility model to achieve the above object, takes following technical scheme to be achieved:
A kind of hot air drying box, including being equipped with the babinet of internal cavity and setting heating unit outside the enclosure, in the babinet Cavity is equipped with intake stack and return air duct, and the intake stack is equipped with several exhaust outlets, and return air duct is equipped with several A return air inlet, heating unit connect the air inlet of intake stack by hair-dryer, and the air outlet of return air duct is connected by exhaust fan Connect heating unit.
Preferably, the intake stack and return air duct are both provided with two, and the return air duct is symmetrically mounted on The upper and lower surface of babinet internal cavity, intake stack are mounted on the inside of return air duct, and the exhaust outlet of two intake stacks is opposite to be set It puts.
Preferably, the surface of the babinet internal cavity is equipped with insulating layer.
Preferably, the insulating layer is mineral wool.
Preferably, the heating unit is the combustor of natural gas.
Preferably, the babinet internal cavity is also equipped with temperature control device, temperature control device connection control heating dress It puts.
Preferably, the exhaust outlet is provided with the wind deflector of guiding wind direction.
Preferably, the intake stack and return air duct use 304 stainless steels.
The utility model has the advantages that, aluminium sheet is heated by the way of hot air circulation, reduces energy consumption, solves The problem of existing heating tube damage can cause production line to be stopped transport, improve job stability.
Description of the drawings
Fig. 1 is the structure diagram of the utility model embodiment;
Fig. 2 is the partial enlarged view of the utility model embodiment.
Specific embodiment
The embodiment of the utility model is described in detail below in conjunction with attached drawing.
As shown in Figure 1, the structure diagram of the embodiment for the utility model.
In the present embodiment, a kind of hot air drying box, including being equipped with the babinet 1 of internal cavity and setting heating unit outside the enclosure 11,1 internal cavity of babinet is equipped with intake stack 2 and return air duct 3, and the intake stack 2 is equipped with several exhaust outlets 5, return air duct 3 is equipped with several return air inlets 4, and heating unit 11 connects the air inlet 7 of intake stack 2, return air by hair-dryer 9 The air outlet 8 of pipeline 3 connects heating unit 11 by exhaust fan 10.
In entire hot air circulation, after air first passes through the heating of heating unit 11, hair-dryer 9 blows hot wind from air inlet 7 Into in intake stack 2, the hot wind of high temperature is discharged from the exhaust outlet 5 of intake stack 2, and aluminium sheet is heated;Exhaust fan 10 extracts Air after heat exchange enters return air duct 3 from return air inlet 4, and air returns to heating unit 11 from 3 air outlets 8 of return air duct and adds Heat so recycles.This hot air circulation case uses air as heat carrier, realizes circulating-heating, and relatively traditional electrothermal tube adds Heat has lower energy consumption.And electrothermal tube is easily damaged, and maintenance needs remove complete machine, and the entire production line is caused to be stopped transport.This Shen Please in flimsy wind turbine and heating unit can be external, repair is more convenient, has better job stability with respect to heating tube.
In the preferred scheme, the intake stack 2 and return air duct 3 are both provided with two, the return air duct 2 It is symmetrically mounted on the upper and lower surface of 1 internal cavity of babinet, intake stack 2 is mounted on the inside of return air duct 3, two intake stacks Exhaust outlet 5 is oppositely arranged.During heating, aluminium sheet transports between two rows of opposite exhaust outlets, the heat of exhaust outlet discharge Wind can be uniformly heated up the upper and lower surface of aluminium sheet, improve the efficiency and effect of heating.
Preferably, the surface of 1 internal cavity of babinet can set insulating layer 6, improve the heat-insulating property of babinet, insulating layer 6 can Think mineral wool.
Preferably, the heating unit 11 is the combustor of natural gas, opposite Electric heating, with it is lower into This.
Preferably, such as Fig. 2, the exhaust outlet 5 is provided with the air draft plate 12 of guiding wind direction, air draft plate 12 guide hot wind to The position discharge of aluminium sheet improves the efficiency of heating.
Preferably, using 304 stainless steels, that improves pipeline uses the longevity for the intake stack 2 and return air duct 3 Maintenance replacement rate drops in life.
The utility model uses the mode of heating of hot air circulation, reduces energy consumption, simultaneously effective improves the operation is stable Property, reduce maintenance of equipment rate.
Only as described above, the only preferred embodiment of the utility model, when the utility model cannot be limited with this The range of implementation, i.e., generally according to simple made by the content recorded in the utility model claims and utility model specification Equivalent changes and modifications all still belong within the utility model claims scope.In addition, abstract part and title are only For patent document search is assisted to be used, not it is used for limiting the interest field of the utility model.
