Abstract
The utility model discloses an air circulating device for stretching films. The air circulating device comprises a centrifugal fan, a fan shell, a motor, an air heat exchanger and a static pressure box, wherein the motor drives the centrifugal fan to operate; the centrifugal fan, the fan shell and the static pressure box are formed in the shell; the fan shell comprises an upper air inlet, a lower air inlet and a plurality of air outlets; the air heat exchanger is mounted at the upper air inlet or the lower air inlet; and the air outlets are communicated with the static pressure box. Compared with the prior art, the fan shell and all the air channels are formed in the shell through the improvement of the fan shell in the utility model, so that the air channels do not need to be isolated and less heat is lost; and therefore, the structure is compact and space is saved.
Description
Technical field
The utility model relates to a kind of film production line drawing wind EGR, just relates to specifically a kind of device that circulated air with specified temp is provided for the film stretching typing.
Background technology
Film is widely used in various fields, is product indispensable in the human lives.In manufacture process, film must stretch and finalize the design under specific equilibrium temperature, and purpose is to make film realize the Uniform Tension typing, improves film quality and intensity etc.
Film is when stretching, and is even for guaranteeing film stretching, needs first film to be heated, and heater commonly used is the wind EGR at present.The wind EGR adopts air heat exchanger to add hot blast, utilizes hot blast simultaneously the film upper and lower surface to be heated.Plenum chamber is provided with temperature probe, by the control of steam flow being realized the control to temperature, then the control by adjusting valve, realizes the uniformity of wind, thereby guarantees the uniformity of temperature, makes the film surface temperature difference＜± 1.5 ℃.Yet existing wind EGR has the following disadvantages: the air channel of blower fan, fan scroll and connection fan scroll all is placed in the outside of device case, and thermal loss is more on the one hand, takes up room on the other hand larger.
The utility model content
Based on above-mentioned technical problem, the utility model provides a kind of film stretching wind EGR.
Its technical solution is:
A kind of film stretching wind EGR, comprise centrifugal blower, blower housing, motor, air heat exchanger and plenum chamber, the running of motor drives centrifugal blower, plenum chamber is placed in housing, centrifugal blower and blower housing also all are placed in housing, blower housing comprises up and down two air intake vents and a plurality of air outlet, and air heat exchanger is arranged on air intake vent or lower air intake vent place, air outlet connection plenum chamber.
Preferably, described plenum chamber arranges eight, minute two rows setting; Corresponding described blower housing comprises eight air outlets.
Preferably, be provided with adjusting valve between air outlet and plenum chamber.
Preferably, described centrifugal blower adopts cantilever design, and described motor is phase asynchronous adjustable frequency motor, passes through belt transmission between motor and centrifugal blower.
Preferably, be provided with dividing plate in the inside of plenum chamber.
Preferably, be provided with two-layer orifice plate in top or the bottom of plenum chamber.
Preferably, described air heat exchanger is finned.
Useful technique effect of the present utility model is:
Compared with prior art, the utility model is built in itself and all air channels in housing, thereby need not the air channel is incubated by the reformation of blower shell, and thermal loss is few, and compact conformation, saves the space.It is even that the utility model also has air-out in addition, and the advantage such as have a narrow range of temperature.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment:
Fig. 1 is the fundamental diagram that film stretching is used the wind EGR;
Fig. 2 is the structural representation of plenum chamber;
Fig. 3 is the overall structure schematic diagram that film stretching is used the wind EGR.
In figure: 1-centrifugal blower, 2-blower housing, the phase asynchronous adjustable frequency motor of 3-, 4-fin type air heat exchanger, 5-plenum chamber, 6-housing, 7-adjusting valve, 8-dividing plate, 9-orifice plate one, 10-orifice plate two.
The specific embodiment
By reference to the accompanying drawings, a kind of film stretching wind EGR comprises centrifugal blower 1, blower housing 2, phase asynchronous adjustable frequency motor 3, fin type air heat exchanger 4 and plenum chamber 5, and centrifugal blower 1, blower housing 2 all are built in housing 6 with plenum chamber 5.Centrifugal blower 1 adopts cantilever design, and the sidewall of housing 6 is passed in its rotating shaft, passes through belt transmission between centrifugal blower 1 and phase asynchronous adjustable frequency motor 3.Blower housing 2 comprises up and down two air intake vents and eight air outlets, whole rectangular structure, and fin type air heat exchanger 4 is arranged on lower air intake vent place, air outlet connection plenum chamber 5.Plenum chamber 5 also arranges eight, minute two rows setting, and every row arranges 4, the air outlet corresponding connection one by one of plenum chamber 5 and blower housing 2.Be provided with adjusting valve 7 between air outlet and plenum chamber.Plenum chamber 5 is provided with former and later two air inlets, is provided with dividing plate 8 in the bosom position of plenum chamber 5, is provided with two-layer orifice plate in top or the bottom of plenum chamber 5, is respectively orifice plate 1 and orifice plate 2 10, and orifice plate 1 is different from the perforated area of orifice plate 2 10.
The below describes the course of work of the present utility model:
Phase asynchronous variable-frequency motor 3 drives centrifugal blower 1 rotation that is placed in housing 6 inside by belt transmission, centrifugal blower 1 drives circulated air and enters blower housing 2 from two air intake vents in up and down, 4 heating of passage in transit fin type air heat exchanger, then enter draught fan impeller inside, through the draught fan impeller Stirring, hot blast is mixed, through the blower fan centrifugal action, hot blast is sent into respectively up and down in totally eight adjusting valves 7, open size by regulating adjusting valve, eight adjusting valve 7 air outputs are reached unanimously, consistent thereby assurance enters the air quantity of eight plenum chambers 5 in up and down.After hot blast enters plenum chamber 5, successively through two-layer orifice plate, hot blast is further mixed, then vertically blow to the film upper and lower surface that is stretching, make the film surface temperature uniformity.
Need to prove, under the instruction of this specification, any equivalents that those skilled in the art have done, or obvious variant all should be within protection domains of the present utility model.
