Abstract
The utility model relates to a zero-leakage fan, which comprises a fan shell, an air inlet shell, a first connecting flange, a second connecting flange and a motor, wherein the air inlet shell is arranged at the front end of the fan shell; the first connecting flange and the second connecting flange are respectively arranged at the front end of the air inlet shell and the rear end of the fan shell; the motor is arranged outside the fan shell; the air inlet shell is connected with the fan shell by full weld; sealing gaskets are respectively arranged between the air inlet shell and the first connecting flange and between the fan shell and the second connecting flange; a third connecting flange is arranged at the front end of the motor and connected with the second connecting flange through a fastener; and the sealing gasket is arranged between the third connecting flange and the second connecting flange. The zero-leakage fan provided by the utility model has the advantages that the inner and outer parts of the fan can be completely sealed, so when the zero-leakage fan operates, zero leakage is truly ensured, internal gas cannot be leaked, external air cannot enter the fan, and the problems that the fan is difficult to complete close and the gas is easy to leak are well solved.
Description
Technical field
The utility model relates to a kind of blower fan, relates in particular to a kind of zero leakage blower fan.
Background technique
Blower fan is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure, and it is a kind of driven fluid machinery.During blower fan is widely used in the cooling in engineering, mine, cooling tower, dust discharge and cooling, the apparatus of air conditioning and the domestic electric appliance and ventilates.Blower fan was to be applied in the apparatus of air conditioning and the housed device mostly in the past, be used for carrying and discharge some nontoxic gases, but the actual demand that the field of using along with blower fan gets more and more and produces, blower fan also can be used for carrying some poisonous or radioactive gases, these gases can cause harm to the people, being leaked to external environment also can be to environment, this just need to propose to the sealing of blower fan integral body strict requirement, what but existing blower fan was done in this respect is not fine, the sealing of blower fan integral body is difficult to be guaranteed, blower fan in use, gas leaks out easily, environment to external world so not only, but also can work the mischief to human body.
The model utility content
The utility model purpose is to provide a kind of gas of inside can not let out in order to overcome the deficiencies in the prior art, and outside air also advances the zero leakage blower fan less than the inside.
For achieving the above object, the technical solution adopted in the utility model is: a kind of zero leakage blower fan, comprise Blower Housing, intake grill housing, the first adpting flange, the second adpting flange and motor, the front end of described Blower Housing is provided with the intake grill housing, described intake grill housing front end and Blower Housing rear end are respectively equipped with the first adpting flange and the second adpting flange, described motor is arranged on outside the Blower Housing, and described intake grill housing links to each other with Blower Housing by full weld; Between described intake grill housing and the first adpting flange, be provided with sealing gasket between Blower Housing and the second adpting flange; Described motor front end is provided with the 3rd adpting flange; Described the 3rd adpting flange links to each other with the second adpting flange by fastening piece; Be provided with sealing gasket between described the 3rd adpting flange and the second adpting flange.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
Zero leakage blower fan of the present utility model because the intake grill housing links to each other with Blower Housing by full weld, guarantees that the joint of Blower Housing and intake grill housing is not leaked; Owing between intake grill housing and the first adpting flange, be provided with sealing gasket between Blower Housing and the second adpting flange, guaranteed the full closed of intake grill housing and Blower Housing, so that the difficult leakage of gas; Because the motor front end is provided with the 3rd adpting flange, the 3rd adpting flange links to each other with the second adpting flange by fastening piece, is provided with sealing gasket between the 3rd adpting flange and the second adpting flange, has guaranteed not leak between the output shaft of motor and Blower Housing.Zero leakage blower fan of the present utility model has guaranteed that blower fan inside has been hermetic with the outside, therefore when work, real assurance zero leakage, inner gas can not let out, and outside air also advances less than the inside, well solved blower fan full closed difficulty, the problem of easily leaking.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of zero leakage blower fan of the present utility model;
