CN2802410Y - Fire tunnel bricks of open-type ring roasting furnace - Google Patents

Abstract

The utility model discloses a fire tunnel brick of an open-type ring roasting furnace. The utility model comprises a brick body, and arced surfaces are arranged on the brick body. The arced surfaces are arranged on two corresponding surfaces of the brick body: an upper surface and a lower surface. The utility model designs the front surface facing the airflow direction and the tail surface of the brick body into an arc shape. The section of the brick is greatly enlarged, and the utility model has the advantages of small circulation resistance force for fume, hard occurrence of fracture, etc.

Description

The quirk of open type ring-form calcining furnace draws brick

Technical field:

The utility model relates to a kind of open type ring-form calcining furnace that uses in the production process of industrial aluminum quirk draws brick.

Background technology:

In the production of industrial aluminum, ring-form calcining furnace is used for the prebaked anode that the roasting electrolysis is used, its quirk wall typical temperature is very high, can reach 1180 ℃, add and take on the neglectful collision of stove, be easy to make hopper to deform, for reducing the distortion of hopper, the quirk wall usually adopts and draws brick to increase bulk strength and the air-flow that reasonably distributes.Traditional brick that draws is a rectangle structure, and the area of section of brick body is less, this structure draw brick bigger to the resistance of flue gas circulation, usually can rupture, influenced carrying out smoothly of producing.

Summary of the invention:

The purpose of this utility model is: provide a kind of quirk of the resistance open type ring-form calcining furnace little, not easy fracture to flue gas circulation to draw brick, to overcome above-mentioned the deficiencies in the prior art.

The utility model is to constitute like this: the quirk of open type ring-form calcining furnace of the present utility model draws brick to comprise a brick body (1), is provided with arcwall face (2) on brick body (1), and wherein arcwall face (2) is located on two relative top and bottom of brick body (1).

Compared with prior art, the utility model is designed to arc with the brick body in face of the face of airflow direction front portion and afterbody, and the cross section of brick increases a lot, and its resistance to the flue gas circulation is less, is not easy to rupture.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

The vertical view of accompanying drawing 2 accompanying drawings 1:

Accompanying drawing 3 is the B-B cutaway view of accompanying drawing 2.

The specific embodiment:

Embodiment of the present utility model: as shown in drawings, on two relative top and bottom of brick body (1), arcwall face (2) is set and gets final product, when installing and use, need the arcwall face (2) of brick body (1) is placed in face of the direction of air-flow.

Reality production process in, also can be only on the face of airflow direction, arcwall face (2) be set of brick body (1).

Claims (2)

1. the quirk of an open type ring-form calcining furnace draws brick, and it comprises brick body (1), it is characterized in that: be provided with arcwall face (2) on brick body (1).

2. the quirk according to the described open type ring-form calcining furnace of claim 1 draws brick, it is characterized in that: arcwall face (2) is located on two relative top and bottom of brick body (1).
