Abstract

The invention provides a non-flexible compensator for a wind box branch pipe of a sintering machine. The non-flexible compensator comprises a horizontal sliding device and a plumb extendable device, wherein the horizontal sliding device comprises a base and a sliding ring, the base is a round metal pipe, the lower end of the base is connected with a straight pipe of the wind box branch pipe of the sintering machine, the sliding ring is a circular metal plate and covers the upper end surface of the base, the circle center of the sliding ring is located on the central axis of the base, and the plane of the sliding ring is perpendicular to the central axis of the base; the inner diameter of the sliding ring is smaller than that of the base, and the outer diameter of the sliding ring is larger than that of the base; the plumb extendable device comprises a descending pipe, the upper end of the descending pipe is connected with a bent pipe of the wind box branch pipe of the sintering machine, the lower end of the descending pipe is inserted into an inner hole of the sliding ring and the base, and the descending pipe is in clearance fit with the inner hole of the sliding ring. The heat expansion of the wind box branch pipe of the sintering machine can be compensated well in any direction of a space under the combined action of the horizontal sliding device and the plump extendable device; the non-flexible compensator is long in service life, low in manufacturing cost and convenient to maintain and repair and meets production requirements, and the production cost is greatly reduced.

Description

technical field

[0001] The invention relates to a non-flexible compensator for branch pipes of a bellows of a sintering machine, which belongs to the technical field of sintering equipment. Background technique

[0002] The bellows branch pipe of the sintering machine is the connecting pipe between the bellows of the sintering machine and the large flue. The bellows branch pipe is composed of two parts, an elbow and a straight pipe. The elbow and the straight pipe are connected by a compensator. One end of the compensator is connected to the elbow of the bellows branch pipe, and the other end is connected to the straight pipe of the bellows branch pipe. In sintering production, due to the large temperature change of the working environment (temperature range of 20~350°C), and the sintering machine bellows and large flue are fixed structures, the thermal expansion of the sintering machine exhaust system can only be installed on the bellows branch pipe The compensator is rele...
