Description

The parallel baking oven of a kind of vapour-pressure type

Technical field

The present invention relates to the parallel baking oven of a kind of vapour-pressure type, relate in particular to a kind of baking oven with the structure wind chamber of successively decreasing.

Background technology

Baking oven is widely used in the laboratory, the laboratory, and five metals, photoelectricity, plasthetics, mould, the footwear material, spraying, printing, medical treatment, in the industries such as space flight and institution of higher learning, but there is following problem in traditional baking oven:

1, the hot blast in baking oven is the flowing mode of walking straight up and down, very easily cause in the process of walking about and drying of base material sideslip occurs, and hot blast walk about inhomogeneously, cause drying effect undesirable;

2, baking oven for guarantee that base material walks about smoothly, so the wind chamber of baking oven need to guarantee that base material contacts with the effective of deflector roll with radian, so is difficult to realize increasing by modular mode the length of baking oven, use is restricted;

3, wind chamber design is unreasonable, and blast is easily unbalance, causes the waste of the energy, and exhaust outlet is single design, and therefore selectable occupation mode reduces, and is unfavorable for the oven dry of variety classes base material.

Summary of the invention

The invention provides a kind of baking oven with the structure wind chamber of successively decreasing, by realizing the modular structural design of baking oven with coordinating of chewing of wind, improve simultaneously the dries quantity of base material.

In order to realize purpose of the present invention, the present invention adopts following technical scheme: the parallel baking oven of a kind of vapour-pressure type, its outside has heat-insulation layer, be provided with main air inlet, exhaust outlet in oven interior, the bottom of baking oven is provided with charging aperture, discharging opening and deflector roll, and oven interior also is provided with the wind chamber, and wind has the some groups of equidistant air-breathers that arrange in the chamber, the wind chamber is by air-breather and air draft chamber, and communicating with main air inlet and exhaust outlet respectively forms the circuit of an air intake air draft.

Described air-breather is chewed to join with the inlet scoop by wind and is formed.

Described wind is chewed has two symmetrical inflatable mouths.

Described wind is chewed and is used wind to chew fixture employing knot that can be undone by a pull form, and fixedly two ends are fixed installation.

Described wind chamber is the degression type structure, and namely wind chamber band is gradient, and it is minimum that the height of wind chamber least significant end reaches.

Described wind chamber front end and heat-insulation layer adjacent part have fillet.

Described baking oven bottom also is provided with auxiliary exhaust outlet.

Described deflector roll is by the variable-frequency motor active drive.

Beneficial effect of the present invention is:

1. adopt structure of the present invention, can guarantee effectively that wind chews wind matter and uniformity, the mechanism of successively decreasing in wind chamber meets fluidics, and the cooperation of chewing by wind can effectively guarantee contacting of base material and deflector roll;

2. be not limited by the length of baking oven, can increase arbitrarily module and increase baking oven length to adapt to the dry demand of different materials;

3. wind is chewed by wind and is chewed fixture employing knot that can be undone by a pull form, and fixedly two ends are fixed installation, make wind chew and are demountable structure, are convenient to cleaning;

4. baking oven has auxiliary exhaust outlet, can select the air draft mode adapt according to different substrate materials.

The specific embodiment

The present invention is further described below in conjunction with drawings and Examples:

Referring to Fig. 1 to Fig. 4, the present invention adopts following technical scheme: the baking oven outside has heat-insulation layer 1, be provided with main air inlet 6, exhaust outlet 9 in oven interior, the bottom of baking oven is provided with charging aperture 10, discharging opening 11 and deflector roll 3, oven interior also is provided with wind chamber 5, have the some groups of equidistant air-breathers that arrange in wind chamber 5, wind chamber 5 is by air-breather and air draft chamber 8, and communicating with main air inlet 6 and exhaust outlet 9 respectively forms the circuit of an air intake air draft; Air-breather by wind chew 2 and inlet scoop 4 join and form, wind is chewed 2 and is had two symmetrical inflatable mouths 21, two symmetrical inflatable mouths can guarantee that wind is on the two ends of deflector roll 3, when passing through deflector roll 3 after base material enters from charging aperture 10, wind blows equably on base material, and not only drying effect is good, and guarantees contacting of base material and deflector roll 3, be difficult for sideslip occurs, base material out enters in next process from discharging opening 11 more afterwards.

consult Fig. 5, wind chamber 5 is the degression type structure, be that wind chamber 5 is with gradient, it is minimum that the height of wind chamber 5 least significant ends reaches, in prior art, baking oven is smooth in order to guarantee that base material is walked about, therefore deflector roll and the base material of baking oven have certain cornerite, the air channel is generally that upper air inlet entered parallel wind chamber and chews from wind and blow out, the structure of lower baking oven pump drainage wind, this kind technology can not guarantee effectively that wind is consistent in wind chamber internal flow energy loss, make the inner blast in wind chamber unbalanced, make blast and the wind speed of each wind bottle neck position inconsistent, the base material discontinuity, the left and right sideslip easily occurs, this structural design with radian is in order to guarantee the corner cut between different substrate materials and deflector roll, to be difficult to increase by modular mode the length of baking oven simultaneously, therefore the present invention chews 2 coordinate by wind chamber 5 and wind, enter wind chamber 5 from main air inlet 6 when wind after, when wind is gone to the end in wind chamber 5, wind is loss gradually and weaken ground, therefore need wind chamber 5 to be with gradient balanced to guarantee wind chamber 5 inner blast, make simultaneously deflector roll 3 be subject to wind-force be also equilibrium equally.This moment, wind chamber 5 was not in the situation that have radian still can guarantee effective contact the between base material and deflector roll, because 5 this moments of wind chamber are straight structure, so can easily increase the length of baking oven by modular mode.

Consult Fig. 1 to Fig. 5, wind is chewed 2 and is used wind to chew fixture 22 to adopt the knot that can be undone by a pull forms, and fixedly two ends are fixed installation, therefore is convenient to dismantle wind and chews 2 and clean simultaneously; Wind chamber 5 front ends and heat-insulation layer 1 adjacent part have fillet 12, if adopt the right angle, wind produces turbulent flow and is difficult to guarantee that blast is balanced at the place, right angle; Described deflector roll 3 is by the variable-frequency motor active drive; The baking oven bottom also is provided with auxiliary exhaust outlet 7, according to the variety classes of base material and different technological requirements, the exhaust air rate of main return air inlet 9 and auxiliary exhaust outlet 7 is selected and is controlled, and has guaranteed drying effect.

Consult Fig. 1 and Fig. 5, after wind enters from main air inlet 6 by wind chamber 5 until the end in wind chamber 5, wind by wind chamber 5 enter wind chew 2 with wind to deflector roll 3, the redundance of wind enters main exhaust outlet 9 by air draft chamber 8 again and discharges to the outside, auxiliary exhaust outlet 7 is regulated air draft, according to the needs of drying course, control its exhaust air rates hour when main exhaust outlet 9, the exhaust air rate of auxiliary exhaust outlet 7 is large; Control its exhaust air rate when larger when main exhaust outlet 9, the exhaust air rate of auxiliary exhaust outlet 7 is little or will assist exhaust outlet 7 to close.

Certainly, above diagram only for better embodiment of the present invention, is not to limit the scope of application of the present invention with this, therefore, everyly make equivalent change all should be included in protection scope of the present invention on the principle of the invention.
