用于磨机衬板拆卸孔的密封装置
摘要：
一种用于磨机衬板拆卸孔的密封装置包括螺栓(2)、垫片(3)、垫圈(4)、螺母(5)和橡胶塞(6)，其中橡胶塞的外径≤拆卸孔的内径，将橡胶塞置于拆卸孔内，在橡胶塞中部贯穿一螺栓，螺栓的平头部置于拆卸孔内，螺栓的螺纹部置于拆卸孔外，通过螺栓的螺纹部依次套上垫片和垫圈，然后将螺母旋接在螺栓的螺纹部以使垫片压紧橡胶塞。拆卸孔设在端盖(7)上却用于衬板(1)的拆卸，当拧紧螺母时，借助垫片和螺栓平头部的压力将橡胶塞胀大，胀大的橡胶塞在拆卸孔内产生足够的摩擦力，从而起到密封作用，防止矿浆被甩出。本实用新型的密封装置可以重复使用，经实践证明是一种可靠的密封装置，减少工作现场环境被污染的状况。
摘要（英）：

A sealing device for a dismounting hole of a mill liner plate comprises a bolt (2), a spacer (3), a gasket (4), a nut (5) and a rubber plug (6), wherein an outer diameter of the rubber plug is smaller than or equal to an inner diameter of the dismounting hole, the rubber plug is arranged in the dismounting hole, and the bolt penetrates through the middle of the rubber plug, a flat head part of the bolt is arranged in the dismounting hole, and a thread part of the bolt is arranged outside the dismounting hole, the spacer and the gasket are sleeved through the thread part of the bolt in sequence, and then the nut is screwed on the thread part of the bolt to make the spacer tightly press the rubber plug. The dismounting hole is arranged on an end cover (7) for dismounting a liner plate (1), when the nut is screwed up, the rubber plug is expanded by a pressure of the spacer and the flat head part of the bolt, and the expanded rubber plug generates an enough frictional force in the dismounting hole to implement a sealing effect, thereby ore pulps can be prevented from being thrown out. The sealing device disclosed by the utility model can be reused, and can reduce an environment pollution of a work site; proved by a practice, the utility model is a reliable sealing device.
