Description

A kind of axial flow blower circulated air drying unit for plastic film production

Technical field

The utility model belongs to plastic film and manufactures field, and in particular to a kind of axis stream for plastic film production Blower circulated air drying unit.

Background technique

Existing plastic film drying device is easy to appear the non-uniform phenomenon of drying effect during the drying process, and does not have Thermal energy after drying is recycled, greatly causes the waste of the energy in this way, is unfavorable for popularizing.

Summary of the invention

The utility model discloses a kind of axial flow blower circulated air drying units for plastic film production, on solving State thermal energy waste problem that the hot-air proposed in background technique cannot recycle and the prior art sheet material is heated it is uneven The problem of.

To achieve the above object, the technical solution that the utility model uses includes: a kind of for plastic film production Axial flow blower circulated air drying unit, including axial flow blower, fixed frame, axial flow blower base lower end is equipped with fixed frame, Axial flow blower base is fixedly connected with fixed frame, and the fixed frame lower end is equipped with fan blade, and the fan blade and axial flow blower rotation connect It connects, fan blade lower end is equipped with deflector, and split-wind plate is equipped on the inside of the deflector, and air heating dress is equipped on the outside of the deflector It sets, insulating layer is equipped on the outside of the air heating apparatus, split-wind plate lower end is equipped with the first wind distributing hole plate, the first wind distributing hole plate lower end Equipped with the second wind distributing hole plate.

Preferably, the air heating apparatus is located at deflector lateral wall surrounding.

Preferably, the first wind distributing hole plate is equipped with round hole, the distribution uniform in size of round hole.

Preferably, the second wind distributing hole plate is equipped with round hole, and the size non-uniform Distribution of round hole is interstitial hole Small, surrounding hole is big.

Compared with prior art, the utility model has the beneficial effects that the air by air heating means heats flows through Fan blade forces hot-air to move downward, and by the first wind distributing hole plate and the second wind distributing hole plate, the flow velocity of thermal current is made to tend to uniform Unanimously, and to following sheet material heating, drying processing is carried out, air is by deflector outside later, and is recycled to air heating dress It sets, improves the service efficiency of thermal energy, solve the problems, such as that non-uniform problem is heated in thermal energy waste and the prior art, be conducive to push away It is wide and universal.

Detailed description of the invention

Fig. 3 is the outside schematic diagram of the utility model.

In figure, 1, sheet material, 2, air heating apparatus, 3, axial flow blower, the 4, first wind distributing hole plate, the 5, second wind distributing hole plate, 6, split-wind plate, 7, insulating layer, 8, deflector, 9, fan blade, 10, fixed frame.

Specific embodiment

The utility model is described in further detail below in conjunction with drawings and examples, it is clear that described implementation Example is only the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical Novel protected range.

Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of axial flow blower for plastic film production Circulated air drying unit, including axial flow blower 3, fixed frame 10, it is characterised in that: the 3 base lower end of axial flow blower is equipped with solid Determine frame 10,3 base of axial flow blower is fixedly connected with fixed frame 10, and 10 lower end of fixed frame is equipped with fan blade 9, the fan blade 9 with Axial flow blower 3 is rotatablely connected, and 9 lower end of fan blade is equipped with deflector 8, is equipped with split-wind plate 6, the deflector 8 on the inside of the deflector 8 Outside is equipped with air heating apparatus 2, and insulating layer 7 is equipped on the outside of the air heating apparatus 2, and 6 lower end of split-wind plate is equipped with the first cloth Air holes plate 4,4 lower end of the first wind distributing hole plate are equipped with the second wind distributing hole plate 5.

Further, the air heating apparatus 2 is located at 8 lateral wall surrounding of deflector.

Further, the first wind distributing hole plate 4 is equipped with round hole, the distribution uniform in size of round hole.

Further, the second wind distributing hole plate 5 is equipped with round hole, the size non-uniform Distribution of round hole, round hole Small for interstitial hole, surrounding hole is big.

As shown in Fig. 1 diagrammatic cross-section, the working principle of the utility model is as follows: cold wind is led to by air heating apparatus 2 3 lower end of axial flow blower is crossed, by the influence of split-wind plate 6, hot-air is assigned to each corner, but because of the wind in middle position Larger, the wind speed of surrounding is more relatively small for speed, so the feature big by the small surrounding hole of 5 interstitial hole of the second wind distributing hole plate, it will Intermediate wind speed reduces, then by the way that after the wind distributing hole plate of uniform size of 4 hole of the first wind distributing hole plate, hot-air becomes air velocity and becomes To uniform, temperature is uniform, temperature is reduced after hot air sheet material, and the air that temperature reduces is in the barrier effect of sheet material 1 and upper Under the swabbing action for holding axial flow blower 3, flows through and heat up on the outside of deflector again by air heating apparatus, such air exists It moves in circles in this space, improves the service efficiency of thermal energy, solve the problems, such as that thermal energy waste and prior art heating are uneven Even problem is conducive to popularize.

The part being not directed in the utility model uses or uses for reference prior art and can be realized.

These are only the preferred embodiment of the present invention, is not intended to restrict the invention, for those skilled in the art For member, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification, Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
