Description

Cabinet type centrifugal fan of glass steel

Technical Field

The utility model belongs to the technical field of cabinet type centrifugal fans, and particularly relates to a glass fiber reinforced plastic cabinet type centrifugal fan.

Background

The centrifugal fan is a driven fluid machine which increases the pressure of gas and discharges the gas by means of input mechanical energy, and the cabinet type centrifugal fan is an ideal product for ventilating and discharging the smoke in places such as hotels, restaurants, auditoriums, movie theaters, basements, industrial and mining enterprises, office buildings and the like;

when the fan starts work, dust and greasy dirt in the air can the adhesion in the intake stack, and long-term going can lead to the intake stack to block up, and current centrifugal fan's structure is complicated, and is difficult to avoid the intake stack to block up.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems and provide the glass fiber reinforced plastic cabinet type centrifugal fan which is simple in structure, can effectively avoid blockage of an air inlet pipeline and is reasonable in design.

The utility model realizes the purpose through the following technical scheme:

the utility model provides a glass steel cabinet type centrifugal fan, includes the fan shell, be equipped with an air inlet section of thick bamboo and an exhaust section of thick bamboo on the fan shell, be equipped with antiseized subassembly in the air inlet section of thick bamboo, antiseized subassembly is including the annular groove of locating the air inlet section of thick bamboo end of ventilating, be equipped with annular installed part in the annular groove, the interior circle of annular installed part is equipped with a plurality of groups blend stop, the surface of blend stop is equipped with the rubber sleeve, be equipped with protruding piece on the inside wall of blend stop.

As a further optimized scheme of the utility model, the annular mounting piece is detachably connected with the air inlet cylinder; the design aims at that: the air inlet barrel is convenient to take down, and the air inlet barrel is cleaned.

As a further optimization scheme of the utility model, the barrier strips are arranged on the inner ring of the annular mounting part at equal angles, the barrier strips are made of metal steel, and the inner surfaces of the barrier strips are in arc concave structures; the design aims at that: the barrier strips are uniformly distributed, so that the contact area between the barrier strips and the air flow is increased conveniently.

As a further optimized scheme of the utility model, the protruding pieces are made of rubber and are uniformly distributed on the inner side wall of the barrier strip; the design aims at that: the dust-proof air inlet pipe has the advantages that the dust-proof air inlet pipe can play a role in adhering dust in air flow, the dust is prevented from adhering to the inner side wall of the air inlet pipe, and the blockage of the air inlet pipe can be effectively avoided.

The utility model has the beneficial effects that: simple structure, and can effectually avoid the intake stack to block up reasonable in design.
