Abstract

The invention relates to a drag hook combined brick for a boiler of a power station. The drag hook combined brick comprises a female brick body and a male brick body, wherein one end face of the female brick body and one end face of the male brick body are boiler body contact faces; a pull rod channel is arranged on the face, matched with the male brick body, of the female brick body; one end of the pull rod channel communicates with the boiler body contact faces; the other end face of the pull rod channel communicates with a pull rod end plate trough; the other end faces of the female brick body and the male brick body are boiler interior contact faces; the face, matched with the male brick body, of the female brick body is further provided with a groove; and a protrusion is arranged on the corresponding matched face of the male brick body. One side face of the female brick body and one side face of the male brick body are provided with positioning protrusions while the other side face of the female brick body and the other side face of the male brick body are provided with positioning grooves. The drag hook combined brick is firmly fixed to the inner side of the boiler wall and is not prone to falling off.

Description

A kind of station boiler drag hook modular tile

Technical field

The present invention relates to application to refractory field, it is specifically related to a kind of station boiler drag hook modular tile.

Background technology

The principle of work of station boiler produces superheated vapour, in order to promote steam wheel, thermal cycling mode can be multiple mode, such as natural circulation station boiler, pump circulation station boiler etc., wherein adopt the boiler of fire room combustion system due to up to more than more than 50 meters, boiler inner wall must build the refractory brick of one layer of suitable thickness, to ensure the continuous and steady operation of whole boiler, refractory brick and boiler wall combine must be very firm, if occurring coming off or collapsing, cause the overall maintenance down in power station, to seriously affect the operating performance in whole power station, it is more good that refractory brick and furnace wall combine, the working time of station boiler is more long, overall operation cost is more low.

Summary of the invention

Goal of the invention: it is an object of the invention to overcome deficiency of the prior art, it is provided that one is firmly fixed on inside furnace wall, the station boiler of difficult drop-off drag hook modular tile.

Technical scheme: in order to solve the problems of the technologies described above, a kind of station boiler drag hook modular tile of the present invention, comprise female brick body and male brick body, it is body of heater contact surface at an end face of female brick body and male brick body, the mating surface of female brick body and male brick body is provided with pull bar passage end and body of heater contact surface through, the other end end face and pull bar end plate groove are through, it is contact surface in stove at an end face of female brick body and male brick body, the mating surface of female brick body with male brick body is provided with groove, it is provided with projection in the corresponding matching face of male brick body, the one side of female brick body with male brick body is provided with positioning convex, the another side of correspondence is provided with location groove.

Described in further: described pull bar passage is semicircle.

Described in further: described pull bar end plate groove is half rhombus.

Described in further: described groove and projection are two, are arranged on the both sides of pull bar end plate groove.

Described in further: described groove, projection, positioning convex, location groove are semicircle.

Useful effect: the brick body by rod assembly, female brick body and male brick body being combined into when station boiler drag hook modular tile of the present invention uses firmly is fixed on inside furnace wall, difficult drop-off.
