Abstract
The utility model provides a rotary bearing mechanized cement vertical kiln used for producing cement, which is an improvement of the original rotary bearing mechanized vertical kilns. The rotary bearing structure is mainly altered, and a kiln sealing device is arranged between the lower rotating part and the lower crushing plate of the kiln body. In this way, the carrying capacity of the rotary bearing is improved; the gap of the bearing, the seal and an isolating block are altered; the rotary bearing is suitable for working in high temperatures place; thus, the phenomenon of the stiff rotation or non rotation caused by heat expansion and cold contraction isn't generated. The sealing device is added, causing the gear transmission (exposed drive) can fill the oiling under the condition of the influence of dust; the working environment of the kiln is altered, and the service life is increased.
Description
The utility model relates to a kind of stove equipment, especially a kind of mechanization cement in vertical kiln.
In the manufacture of cement industry, various stoves were all brought in constant renewal in recent years, as the tower mechanized cement shaft kiln of revolution that occurs recently, generally used in manufacture of cement, and its result of use is also better, but the disadvantage of its existence is very difficult when changing consumable accessory.And its frame for movement is reasonable inadequately again, structure and material design as supporting are reasonable inadequately, when it is at high temperature worked, easy expanded by heating and make steel ball roll dumb or do not rotate, again since in the body of heater with its underpart discharging part [rotating part] between not solution of sealing problem, cause a large amount of dust to fly out, often all topped pivoting support and big pinion, so that can't rotate, gear drive is the open type transmission, more is not easy to oily etc.
The purpose of this utility model is to design a kind of mechanized cement shaft kiln that manufacture of cement is used that is suitable in order to overcome above-mentioned weak point, and its characteristics mainly are the structures of having improved pivoting support, comprise the size that adds big steel ball, increase it to be subjected to loading capability; Because of the nylon spacing block of supporting can not use in temperature is 200～300 ℃ stove, so change it into steel ball, its diameter is smaller; Again because of its rubber seal melts inefficacy easily, it is changed into pure wool makes, for the steel ball in preventing to support in the shrinkage of expanding of kiln internal cause pad, it can not be rotated and strengthen it axially and radial clearance.Simultaneously for solving the inside and outside sealing problem of kiln, between its rotating part and fixing kiln body bottom, designed a kind of sand seal structure, make it to have solved well sealing problem, through the type approval test use, obtained good effect.
