Description

Blower for power plant

Technical Field

The utility model relates to a power plant uses the forced draught blower, especially relates to a but power plant of automatically cleaning uses the forced draught blower.

Background

A power plant, also called a power station, is a plant that converts various primary energy sources stored in nature into electric energy. With the increase of power demand, the development of motor manufacturing technology and the expansion of electric energy application range, power plants are produced accordingly. The most widely applied power plant is a thermal power plant relying on thermal power generation, for example, a Huaneng octagonal power plant 'high-pressure and small' new construction is used for constructing 2 60-kilowatt domestic ultra-supercritical coal-fired power generating sets, and heat supply is also realized. The project is that the first domestic auxiliary machine adopts a single-series 670 megawatt ultra-supercritical double-extraction heat supply unit.

When the power plant generates electricity, the air blower feeds air required by fuel combustion into a power device of the boiler to enable the fuel in the boiler to be fully combusted, but during actual use, dust in the boiler enters the air blower and is accumulated on an air blower unit, the air blowing efficiency of the air blower is affected, and the service life of the air blower is shortened. Some current air feeder units that have filtering mechanism only simply filter the dust, and the dust adsorbs on the filter screen, if not in time clear up, can influence the air supply efficiency of forced draught blower equally.

In view of this, the present application is specifically made.

The periphery of filter screen is by locating the rotation base in the third gear drive of one side rotatory, the filter screen with link up with the ring gear between the third gear. The third gear is driven to drive the gear ring, and then the filter screen is driven to rotate.

The motor with be equipped with first gear on the rotation axis between the flabellum, be equipped with on the mounting bracket and be on a parallel with the dwang of blast pipe, be equipped with on the dwang with the second gear that first gear corresponds, the dwang end passes the rotating base and with third gear shaft is connected. Therefore, the first gear can be driven by the motor, the second gear is driven by the first gear, the third gear is driven by the second gear, and finally the filter screen is driven to rotate, so that the fan blades and the filter screen are driven by one set of motor.

The cleaning system is a cleaning brush fixedly contacted with the surface of the filter screen and a fixture thereof.

The fixed object is a cleaning rod which is fixedly connected to one side of the rotating base and is parallel to the filter screen. The tail end of the cleaning rod exceeds the central point of the filter screen.

The cleaning brush is generally a hairbrush.

The application provides a forced draught blower for power plant compares prior art, has following beneficial effect:

through designing automatically cleaning system, drive first gear promptly through the motor, first gear drives the second gear, the second gear drives the third gear again, finally drive the filter screen and rotate and by the clearance brush clearance, it leads to the dust to pile up on the filter screen to have avoided long-time work of filter screen, the filtration efficiency of filter screen has been improved, avoid the staff to change the filter screen often simultaneously, the live time and the life of filter screen are improved, use cost is reduced, convenient to use person uses, the design is simple, convenient operation is laborsaving, be suitable for extensive popularization and application.
