Online rapid repairing device for dewaterer gear ring

Abstract

The invention relates to an online rapid repairing device for a dewaterer gear ring, and belongs to the technical field of blast furnace slag processing equipment. The online rapid repairing device comprises a gear ring which is composed of two semi-circular backing rings, through holes are evenly distributed in each backing ring, an arc-shaped plate is fixedly connected to the outer side of each backing ring, connecting holes are formed in each arc-shaped plate, the positions of the connecting holes correspond to those of the through holes formed in the backing rings, and hing pins are installed in the connecting holes and the through holes. The online rapid repairing device for the dewaterer gear ring has the advantages that rapid online repairing of the dewaterer gear ring can be achieved, operation is easy, and normal operation of a dewaterer is not influenced.

Description

technical field [0001] The invention relates to an online rapid repair device for a ring gear of a dehydrator, belonging to the technical field of blast furnace slag treatment equipment. Background technique [0002] At present, the treatment of blast furnace slag is generally carried out by water quenching, which requires the separation of slag and water after water quenching, so as to realize the safe and effective transportation of slag. At the same time, the separated water can be further recycled to reduce water consumption. The usual method is to use a dehydrator device. The inside of the dehydrator is covered with screens, and the outer ring is a ring gear. The power device drives the pinion, and the pinion and the large gear mesh to realize the rotation of the dehydrator and then realize the separation of slag and water. [0003] At present, the blast furnace tends to be larger, and the blast furnace produces more slag per unit time. Correspondingly, the dehydrator a...

Problems solved by technology

The aperture supporting each pin shaft bears a large alternating load during operation. Due to wear and corrosion during the production process, the meshing part of the pin shaft and the pinion and the joint between the pin shaft and the aperture are prone to wear and tear, and the pin shaft swings. The wear and tear intensifies, resulting in the unstable rotation of the dehydrator, which has a serious impact on the entire transmission system, mainly manifested in the breakage of the toothed coupling in the transmission part, and the wear of the aperture and pin shaft is intensified

If the support ring is replaced as a whole, the construction on site will be difficult, and it will be difficult to find the alignment, and the construction quality cannot be guaranteed; at the same time, due to the harsh construction environment on site, personal safety accidents are prone to occur; in addition, the long construction period will also affect the normal production of the blast furnace
