A kind of film cools down circulating blowing device
Technical field
The utility model is related to rubber tooling technical field, specifically a kind of batch off unit.
Background technology
General, the blower system of existing batch off unit is another side-blown normal using the side of axial flow blower slave unit
Warm air, film temperature is reduced by way of carrying out heat exchange with internal film, enable its outlet port temperature with
Room temperature is approached, and normal temperature air is directly entered the gas extraction system of user by the side wind-collecting cover after other side is reached.
The problem of current technology is present has:
1st, normal temperature air residence time in equipment is about 2s, and energy dissipation is serious, and gas extraction system is huge, cost of investment
Greatly:
2nd, each blower fan air intake for convenience, blower fan is needed all installed in outside, fan noise greatly, to shopwork shadow
Sound is huge;
3rd, because blower fan is mounted in the same side of equipment, cause film cooling effect uneven;
4th, a large amount of impurity in air, dust can enter equipment, influence the quality of film;
5th, because air utilization ratio is low, it is necessary to which the axial flow blower quantity installed is more.
Utility model content
In order to solve the above technical problems, the utility model, which provides a kind of film, cools down circulating blowing device, carried with reaching
The purpose of high cooling effect.
To reach above-mentioned purpose, the technical solution of the utility model is as follows:
A kind of film cools down circulating blowing device, including frame and the bottom support frame positioned at bottom of the frame, the frame
Top is sealed by lamina tecti, and bottom is sealed by bottom tank, and the frame two ends are respectively equipped with air intake cover and outlet housing, described
Frame both sides are arranged at intervals blower fan, the blower fan peripheral hardware organic frame seal closure along frame central axis.
In such scheme, the blower fan two is one group, is arranged side by side in the both sides of frame.
In such scheme, the frame inner top hangs with film.
By above-mentioned technical proposal, the film cooling circulating blowing device that the utility model is provided improves the circulation of air
Mode, is carried out by the way of interior circulation, and the front end for making it into the air order slave unit of device interior is progressively circulated
To the rear end of equipment, heat exchange is carried out with film to greatest extent.Air enters the circulatory system from air intake cover, in the effect of blower fan
Under, the left and right circulation in device is finally excluded, air has carried out sufficient heat exchange with film in the process from air leaving cover,
Reach the effect of reduction film temperature.
The present apparatus enhances the security and stability of equipment, improves the service efficiency for entering gas, reduces pollutant entrance
Equipment, greatly reduces the noise of equipment.The present apparatus is reasonable in design, simple in construction, safe and reliable, easy to use, be easy to dimension
Shield, has good value for applications.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe.
The utility model provides a kind of film and cools down circulating blowing device, and structure as shown in Figure 1, the device can be carried
Height enters the service efficiency of gas, is conducive to cost-effective.
Film cooling circulating blowing device as depicted in figs. 1 and 2, including frame seal closure 1, blower fan 2, film 3, top cover
Plate 4, air intake cover 5, outlet housing 6, bottom support frame 7, bottom tank 8, frame 9, film 3 are hung on the inner top of frame 9.
Frame 9 is integrally attached to above bottom support frame 7, one group of blower fan 2 two, along frame 9 along frame central axis
Interval is arranged side by side, and is sealed by frame seal closure 1, and the top of frame 9 is sealed by lamina tecti 4, and bottom is sealed by bottom tank 8, is entered
Fan housing 5 and outlet housing 6 are arranged on the two ends of frame 9.
Air enters the circulatory system from air intake cover 5, in the presence of blower fan 2, the left and right circulation in device, finally from air-out
Cover 6 is discharged, and air has carried out sufficient heat exchange with film in the process, reaches the effect of reduction film temperature.
It can be seen that from the arrow in Fig. 1, the present apparatus mainly improves the endless form of air, is entered by the way of interior circulation
OK, the front end for making it into the air order slave unit of device interior progressively circulates the rear end of equipment, to greatest extent
Heat exchange is carried out with film.
The present apparatus has the advantage that:
1st, one end of air slave unit enters, and is excluded after repeatedly circulation, sufficient heat exchange from the other end, gas extraction system
It is less about more than 80/%, investment reduction cost;
2nd, blower fan reduces equipment noise all installed in the inside of equipment, transforms workshop noisy environment;
3rd, blower fan is installed in equipment with equipment axisymmetrical, when film passes through different positions, can be cooled down different
Position, is that film can sufficiently realize uniform cooling;
4th, as a result of sealed installation environment, the entrance of dust is greatly reduced, prevents film to go out in cooling
Existing situation occurs;
5th, the efficiency of air heat exchange is improved, greatly reduces the quantity of blower fan.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality
Type.A variety of modifications to these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice can in other embodiments be realized in the case where not departing from spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
