Description

Centrifugal blower with silencing and purifying functions

Technical Field

The utility model relates to a centrifugal blower technical field, concretely relates to centrifugal blower who possesses silence, purification performance.

Background

In transformer substation owner becomes room, condenser room, reactance room and used change the room, if temperature and humidity exceed the warning value when, need carry out corresponding operation cooling dehumidification process, traditional processing mode sets up the exhaust fan, but this kind of mode amount of wind is less, brings into dust impurity in addition easily, still possesses very big noise simultaneously, has very big limitation.

Therefore, a centrifugal blower having a silencing and purifying function is proposed.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

The utility model provides a not enough to prior art, the utility model provides a centrifugal blower who possesses silence, purification performance has overcome the not enough of prior art, reasonable in design, and compact structure has solved current exhaust fan amount of wind less, brings dust impurity into in addition easily, still possesses the problem of very big noise simultaneously, the utility model discloses a simple structure combination adopts centrifugal fan, has improved the amount of wind, sets up the multilayer filter screen at the air intake simultaneously, can completely cut off the dust, in addition through setting up the acoustic celotex board, has reduced the noise, has very strong practicality.

(II) technical scheme

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:

a centrifugal blower with silencing and purifying functions comprises a shell, wherein the bottom wall of the shell is provided with an air inlet, and a filter screen is arranged on the air inlet; the inner wall of the shell is provided with a reinforcing plate which is obliquely arranged, the reinforcing plate is provided with a through hole, a centrifugal fan is arranged in the through hole, a driving shaft of the centrifugal fan is connected with a driving motor, and the driving motor is fixed on the reinforcing plate;

an air outlet is formed in one side, away from the filter screen, of the reinforcing plate, and an induced draft cover corresponding to the air outlet is connected to the shell and the reinforcing plate.

Furthermore, the inner wall of the shell is connected with a sound insulation board.

Furthermore, a shock pad is arranged at the joint of the driving motor and the reinforcing plate.

Furthermore, the filter screen is arranged by metal and is of a multilayer structure.

Further, the sound insulation board is of a double-layer structure.

(III) advantageous effects

The embodiment of the utility model provides a possess silence, purification performance's centrifugal blower.

The method has the following beneficial effects:

1. adopt centrifugal fan, improved the amount of wind, set up the multilayer filter screen at the air intake simultaneously, can completely cut off the dust, through setting up the acoustic celotex board in addition, reduced the noise, have very strong practicality

2. Divide into two regions with the cavity through setting up the gusset plate, can block the wind noise of air inlet, cooperation acoustic celotex board can the noise abatement.

3. Through multiple measure noise abatement, acoustic celotex board on the shell inner wall can the noise reduction, adopts centrifugal fan moreover, also can the noise abatement, through shock pad with driving motor and gusset plate interconnect in addition, also can reduce driving motor's vibration, noise abatement pollution comprehensively then.

Drawings

FIG. 1 is a schematic top sectional view of the present invention;

fig. 2 is a schematic side view and sectional view of the structure of the present invention.

In the figure: the device comprises a shell 1, a sound insulation plate 1.1, a filter screen 2, a reinforcing plate 3, a centrifugal fan 4, a driving motor 5, an induced draft cover 6 and an air outlet 7.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
