Description
Technical field
The present invention relates to a kind of baking ovens, more particularly relate to a kind of heated-air circulation oven, belong to pharmaceutical equipment technical field.
Background technique
In drug production process, usually raw materials certain in drug are dried, what is be commonly used at present is
Heated-air circulation air box, wind regime drives wind wheel via heater by circulation air supply motor, and hot wind is sent out, then via air duct to baking
Case interior room, then air sucking air duct after using become wind regime recirculation, and heating uses.Common heated-air circulation oven wind
Machine is very uneven to the heating of interior room in cabinet two sides, simultaneously because two sides are disposed with heating tube, so encountering high temperature oven
In the case of motor is cooled down it is necessary to other water receiving pipe, it is very inconvenient to have waste of energy.
Summary of the invention
Goal of the invention: present invention aims in view of the deficiencies of the prior art, provide a kind of homogeneous heating, it is energy saving,
Heated-air circulation oven easy to use.
Technical solution: a kind of heated-air circulation oven of the present invention including cabinet, is set to the exhaust air flues of cabinet two sides
With the level shelf for being set to the box house, blower is arranged in the top of cabinet, and the air duct of the blower is designed in R type, institute
The tail portion for stating R type air duct is connected to the exhaust air flue of the side wall of the cabinet, and the head in R type air duct is set to the cabinet
The center at top, the blower is set to the head in R type air duct, and is connected to the inside of the cabinet.
Technical scheme is further defined to, and the blower is long-shaft type axial flow blower.
Further, thermal insulation layer is set between R type air duct and the top of the cabinet.
Further, the tail portion air inlet in R type air duct is also connected with mend wind passage.
Further, heating tube is set in the exhaust air flue of the cabinet two sides.
Further, the top of the cabinet also sets up wet-emitting blower, the air inlet of the wet-emitting blower and the cabinet
Inner cavity connection.
The utility model has the advantages that the present invention provides a kind of heated-air circulation oven, blower is placed on top, and use long-shaft type axis stream wind
There are thermal insulation layer in machine, centre, and high temperature is avoided to influence motor work, also do not need water cooling, convenient and energy saving；The air duct of blower uses
R type increases the air quantity of air inlet, ensure that the uniformity of air inlet, meanwhile, air intake passage is significantly greater than air-out passage, increases
Wind pressure uses wind velocity faster, and impulse force when air-flow enters cabinet from top to down is big, make it is dry more evenly.
Detailed description of the invention
Fig. 1 is the overall structure figure of heated-air circulation oven provided by the invention；
Fig. 2 is the structural perspective of heated-air circulation oven provided by the invention；
Fig. 3 is the structural schematic diagram in R type provided by the invention air duct.
Specific embodiment
Technical solution of the present invention is described in detail below by attached drawing, but protection scope of the present invention is not limited to
The embodiment.
Embodiment 1: a kind of heated-air circulation oven including cabinet 1, is set to the outlet air of 1 two sides of cabinet as shown in Figure 1, 2
Heating tube is arranged in the exhaust air flue of 1 two sides of cabinet in air duct and the level shelf being set to inside the cabinet 1.
In the present embodiment, blower 2 is arranged in the top of cabinet 1, and the blower 2 is long-shaft type axial flow blower, axial fan
It is typically used in the place of ventilation, and uses long-shaft type axial flow blower in the present embodiment, by adding to blower rotary shaft
Long design, increases the distance between blower and heating tube, avoids the excessively high work for influencing blower of temperature.
The air duct of the blower 2 is designed in R type, the outlet air wind of the side wall of the tail portion in R type air duct 3 and the cabinet 1
Road 4 is connected to, and the head in R type air duct is set to the center at 1 top of cabinet, and the blower 2 is set to the R type
The head in air duct 3, and be connected to the inside of the cabinet 1.The design in R type air duct, increases intake, ensure that the equal of air inlet
When even property, while air intake passage is significantly greater than air-out passage, increases wind pressure, uses wind velocity faster, air-flow enter cabinet from
Impulse force under above is big, makes drying more evenly.
In addition, air loss is had in the cyclic process of blower 2, in order to guarantee the adequacy of hot wind, the R of the application
The tail portion air inlet in type air duct 3 is also connected with mend wind passage 6, opens mend wind when necessary.
Thermal insulation layer is set between R type air duct 3 and the top of the cabinet 1, further reduces high temperature to electricity
The influence of machine does not need further water cooling in an environment of high temperature yet, convenient and energy saving.
The top of the cabinet 1 also sets up wet-emitting blower 7, the inner cavity of the air inlet of the wet-emitting blower 7 and the cabinet 1
Connection when humidity is larger in cabinet, starts wet-emitting blower 7 after circulation baking oven operation a period of time, and the big air of humidity is arranged
Out.
As described above, must not be explained although the present invention has been indicated and described referring to specific preferred embodiment
For the limitation to invention itself.It without prejudice to the spirit and scope of the invention as defined in the appended claims, can be right
Various changes can be made in the form and details for it.
