Abstract

The utility model relates to a special extracting tool of ash storehouse top sack cleaner impeller. At present, when two fan impellers of the bag-type dust remover at the tops of a coarse dust reservoir and a fine dust reservoir of a thermal power plant are disassembled, the fan impellers are required to be heated, the fan impellers are taken down from a motor shaft by a method of pounding with a big hammer, the disassembling speed is too slow, and the fan impellers are easy to damage. The utility model provides a special extracting tool of ash storehouse top sack cleaner impeller, its constitution includes: round steel (1), the length of round steel is 150mm, and the diameter is 120mm, offers shaft hole (2) the same with the outside diameter of axle of impeller at the inside center of the 50mm length of one end of round steel, and the equidistance all around of the 50mm length of one end of round steel has offered four the same jackscrew holes (3), and four jackscrew holes are on the coplanar, and threaded hole (4) are offered to the inside center of the other end 100mm length of round steel, and threaded hole inserts M24's lead screw (5). The utility model discloses be applied to the hot spot field of removing dust.

Description

Special extracting tool of ash storehouse top sack cleaner impeller

Technical Field

The utility model relates to a special extracting tool of ash storehouse top sack cleaner impeller.

Background

When the impellers of the two bag-type dust remover fans at the tops of the coarse dust reservoir and the fine dust reservoir of the Huanen Heilal thermal power plant are disassembled, the impellers are required to be heated, the impellers are taken down from a motor shaft by a method of hammering with a big hammer, the disassembling speed is too slow, and the impellers are easy to damage.

Disclosure of Invention

The utility model aims at providing a special extracting tool of ash storehouse top sack cleaner impeller.

The above purpose is realized by the following technical scheme:

the utility model provides a special extracting tool of ash storehouse top sack cleaner impeller, its constitution includes: the round steel, the length of round steel be 150mm, the diameter is 120mm the inside center of one end 50mm length of round steel set up the shaft hole the same with the outside diameter of axle of impeller, the one end 50mm length of round steel all around the equidistance seted up four the same jackscrew holes, four the jackscrew hole on the coplanar, the inside center of other end 100mm length of round steel set up threaded hole, the threaded hole in insert M24's lead screw.

The special disassembling tool for the impeller of the bag-type dust collector at the top of the ash storehouse is characterized in that M12 jackscrews are inserted into jackscrew holes.

The special disassembling tool for the impeller of the bag-type dust collector at the top of the ash storehouse is characterized in that the threaded hole is an M24 threaded hole.

The utility model has the advantages that:

1. the utility model has the advantages of being simple in structure and convenient in operation, can avoid damaging the impeller, reduce the work load of dismantling the process, reduce intensity of labour, reduce operating time. The fan impeller can be quickly disassembled, the impeller is prevented from being damaged when the sledge hammer is used for disassembling, and personal injury can be avoided.

2. The utility model discloses a diameter 120mm, length 150 mm's round steel preparation extracting tool. A hole which is the same as the outer shaft neck of the impeller is processed in the center of the inner part with the length of 50mm at one end, and 4M 12 jackscrews are adopted around the hole to clamp the special tool on the impeller. The other end of the impeller is 100mm long, the inner center of the impeller is provided with M24 threads, and the impeller is ejected out of the motor shaft by a screw rod of M24.

3. The utility model discloses a special lead screw needs to use the high-strength lead screw. The inner hole diameter of the special tool needs to be tightly combined with the impeller, and the special tool is firmly fixed on the shaft by a jackscrew.
