Abstract
The utility model which belongs to the fan field provides a blower or induced draft fan device which can work under higher air pressure by aiming at the disadvantage that the current fan can not work under high pressure. The utility model which comprises a fan and a drive mechanism for the fan is characterized in that a pressure container is provided, at least the fan is arranged in the pressure container; wherein the pressure container has an air inlet and an air outlet; the inlet of the fan is communicated with the inner cavity of the pressure container and the outlet of the fan is connected with the air outlet of the pressure container. The utility model is applicable for conveying various gases, in particular to the flammable, explosive, toxic and harmful gases.
Description
Technical field
The utility model relates to the blower fan field, particularly a kind of air blast or blower unit.
Background technique
Blower fan commonly used in the industry has kinds such as centrifugal fan, axial fan, vortex type blower fan and roots blower, and in different operating modes, blower fan can be used for air blast, also can be used for air inducing.The sort of blower fan all has a suction port and a relief opening, air or process gas enter fan casing by suction port, through the blower fan adherence pressure, are discharged by relief opening again, the pressure of discharging gas is higher than the pressure that sucks gas, and its difference is commonly referred to as boosts.Different blower fans its to boost be different, people utilize boosting of blower fan to overcome system resistance in the commercial plant, finishing some manufacturing process, and the pressure of different its working gass of manufacturing process is different.The working pressure of blower fan comprises boosting of blower fan and sucks the pressure of gas that for a selected blower fan, it boosts is certain value.Common blower fan is owing to its structure and material, and the working pressure that casing can bear is less, is usually less than 0.1MPa.If the pressure of working gas is higher, fan casing is easy to damage, so the application area of present common blower fan is subjected to certain restriction, promptly existing common blower fan can only be used in the lower occasion of air pressure.In some cases, often need the working gas of elevated pressures is boosted once more, because above-mentioned, people must not adopt compressor to solve this problem then at present.But carry the compression ratio and the energy consumption of compressor of same gas flow all much higher than blower fan, i.e. compressor incompatibility low compression ratio occasion, and the cost of compressor is also high a lot of than blower fan.
Summary of the invention
Technical problem to be solved in the utility model is can not provide a kind of air blast or the blower unit that can work under the higher situation of air pressure in the shortcoming of high pressure operation at existing blower fan.
The technological scheme that addresses the above problem is: a kind of air blast or the blower unit that are provided, the drive unit that comprises blower fan and blower fan, specialization of the present utility model is, be provided with a pressurized container, among placing this pressurized container to the said blower fan of major general, wherein pressurized container has suction port and relief opening, and the suction port of said blower fan communicates with the inner chamber of this pressurized container, and the relief opening of blower fan links to each other with the relief opening of pressurized container.Working gas enters pressurized container by the suction port of pressurized container, and the suction port by blower fan enters blower fan then, is discharged by the relief opening of blower fan again.If air pressure height, it then in the pressurized container a kind of hyperbaric environment, whole blower fan also just is among the hyperbaric environment, angle from stress balance, fan casing and other component can not damaged because of air pressure is high, thereby have guaranteed that blower fan still can move normally under the air pressure condition with higher.
For the ease of making and installing, above-mentioned pressurized container can be made up of container shell and container end, and the relief opening of pressurized container preferably is located on the container end; Certainly, also can be located on the container shell.
According to the installation situation of working equipment, the suction port of said pressurized container can be located on the container end, also can be located on the container shell.
Above-mentioned fan drive device can be placed in the above-mentioned pressurized container, also can be placed on outside the pressurized container.Fan drive device can be a motor, also can be other power plant.
Compared with prior art, the utility model is owing to be installed in blower fan in the pressurized container, and fan air inlet directly sucks gas from internal tank, and it uses the restriction that is not subjected to air pressure, both can under high pressure work, and also can work under lower pressure.The utility model adopts above-mentioned simple mode, does not change the original structure of blower fan and just common blower fan can be become high pressure positive blower, thereby reduced the expense and the energy consumption of existing high-voltage operation.When working gas is easy to generate gas leakage during by common blower fan, and the utility model is installed in blower fan in the pressurized container, even blower fan has leakage, the gas that leaks out also is closed in pressurized container inside, and also can not influence the proper functioning of blower fan, realize " zero reveal " of blower fan environment.The utility model is fit to carry all gases, especially carries inflammable, explosive, poisonous, harmful gas.
Description of drawings
Fig. 1 is the schematic representation of a kind of structure of the utility model.
Fig. 2 is the schematic representation of the another kind of structure of the utility model.
Embodiment:
First embodiment of the present utility model is as shown in Figure 1: blower fan 1 is a roots blower, and pressurized container is made up of housing 2 and end cap 3, and end cap is provided with container air inlet 6 and relief opening 7.For easy for installation, blower fan integral body is fixed together with container end, that is: blower fan 1 is contained on the support 9, and support 9 is fixed on the end cap 3; The suction port 4 of blower fan opens wide, and the relief opening of blower fan 5 is connected with container relief opening 7 on the end cap 3 by connecting tube 8.Connecting tube 8 can be steel pipe, bellows, flexible hose or other flexible pipes.Placement between blower fan relief opening 5, connecting tube 8 and the container relief opening 7 can adopt that flange connects, is threaded, FERRULETYPE connects, flared fitting connects or directly welding.Blower fan 1 adopts motoring, and this motor also is installed on the support 9 and (does not draw among the figure).During blower fan work, gas (air or process gas) is entered in the container shell 2 by container air inlet 6, the gassiness while in container shell 2, this gas is also entered in the blower fan 1 by fan air inlet 4, behind the blower fan adherence pressure, derive by blower fan relief opening 5 again, discharge by the exhaust port 7 of container by connecting tube 8 then.
Another embodiment of the present utility model is as shown in Figure 2: the motor 10 that wherein drives blower fan 1 is placed on outside the pressurized container, and the output shaft 11 of motor 10 is connected with the input shaft of blower fan; With the exception of this, all the other structures are identical with first embodiment.
When the drive unit of blower fan was placed on the pressurized container outside, the drive unit of blower fan can adopt dynamic power machines such as diesel engine, petrol engine.
