Description
Technical field
The present invention relates to furnace equipment technical field, and in particular to a kind of displacement room for atmosphere roller kilns.
Background technology
Full atmosphere roller kilns are the important equipments of the materials such as the nickelic ternary material of production, compared to normal atmospheric roller kilns,
Full atmosphere roller kilns not only carry out hermetically sealed processing to whole roller kilns, and to install displacement room, material additional at burner, stove tail
When into and out of roller kilns, gas displacement will be carried out by the room of displacement, will not be to processing atmosphere in stove into and out of material with guarantee
Impact, then avoid influenceing product quality.
In the displacement room of roller kilns, the valve system of material import and export requires higher sealing when closed.It is existing
The valving for having displacement room is all to be limited using valve plate by roller kilns structure and space come gluing, sealing material import and export, its
Valve plate is to realize opening and closing by two sets of drive mechanisms, when closing material import and export, first drives valve plate lifting fortune by elevating mechanism
Move to face material import and export and keep a determining deviation on conveying material direction with material import and export, then using horizontal force
Mechanism drives valve plate to move along conveying material direction to be close to sealants inlet and outlet, when opening material import and export with said process phase
Instead.This valve system is complicated, cost is high, operation and control difficulty are big, and horizontal force application mechanism is only acted upon on valve plate
Limited several stress points, its stability is poor, be unfavorable for ensure sealing reliability.In addition, limited by roller kilns structure, it is this
Valve system I＆ M difficulty is big.
The opening position of conveying roller rod stretching body of heater requires very high sealing in roller kilns.Existing roller kilns are to conveying
Sealing at roller rod is all to be covered one end sealing that conveying roller rod is stretched out outside body of heater using seal closure, is passed through using power transmission shaft
Installation through-hole connection conveying roller rod and drive mechanism, power transmission shaft on seal closure are fixedly mounted on by bearing block and are fixed in roller-way
On support on kiln body, in the installation through-hole on seal closure install sealing ring with by installation through-hole inwall with and power transmission shaft it
Between clearance seal.This kind of transmission seal structure requires high to the installation through-hole relative positional accuracy of power transmission shaft and seal closure, no
It can then cause poorly sealed or even the problem of can not seal, thus exist and make that processing and assembly difficulty are big, efficiency is low, cost is high
The problem of；Meanwhile in actual production process, power transmission shaft is inevitably driven the active forces such as mechanism, installs bearing
The support of seat can be deformed, and then cause the installation site of power transmission shaft and angle to change, namely can make power transmission shaft and close
The installation through-hole relative position of sealing cover changes, and this can influence installation through-hole and sealing property between power transmission shaft and close
The life-span of seal, and the rotation of power transmission shaft also inevitably abradable seal circle, this also results in the service life of sealing ring
Greatly shorten.In addition, the bearing block of each power transmission shaft is arranged on body of heater by support respectively, all bearings are difficult to ensure that during assembling
At seat in the same plane, namely the conveying roller rod in the same plane, being connected with power transmission shaft is difficult to ensure that at all power transmission shafts
Drive end also the place of being difficult in the same plane, and then makes conveying roller rod also not in the same plane, be unfavorable for the conveying of saggar
Stationarity, or even saggar can be caused not convey.
The content of the invention
The technical problem to be solved in the present invention is to overcome the shortcomings of the prior art, there is provided a kind of simple in construction, occupancy
