Description
Technical field
The utility model is a gas-phase method total density polyvinyl reactor outlet bend pipe rotary support mechanism.
Background technique
The gas-phase method total density polyvinyl device, the generally all corresponding two or more feed bins of polymer reactor outlet, but the outlet bend pipe has only one, can only link to each other with a feed bin when also just saying the reactor ordinary production, in process of production along with bin-level changes, often the reactor outlet feed bin is switched, switching method is that flange between reactor outlet and the bend pipe is disconnected, bend pipe and go the short circuit between the feed bin pipeline to take apart, bend pipe forwarded to will switch the feed bin pipeline side of reaching the standard grade, again with bend pipe with reactor and go the feed bin pipeline to be connected, because of the reactor outlet bend pipe can't carry out fixed support, in taking flange and short circuit process apart, by welding lifting earrings on the bend pipe bend pipe is sling and could be operated with hoist crane, the bend pipe tuning is all wanted many people to operate just to finish at every turn, bring inconvenience to production, simultaneously, the outlet bend pipe only by with sliding support point support at reactor flange connecting and short circuit place, cause that pipeline shakes serious hidden danger in the outlet line discharging process.
The utility model content
The purpose of this utility model is in order to solve the problem that prior art exists, a kind of gas-phase method total density polyvinyl reactor outlet bend pipe rotary support mechanism is provided, realization response device outlet feed bin switches fast, can reduce maintainer about 1/2, make things convenient for steady production, for outlet line has increased by two strong points, the discharging pipeline is shockproof simultaneously.
The technical solution of the utility model is: gas-phase method total density polyvinyl reactor outlet bend pipe rotary support mechanism is characterized in that: welding stiffening plate on the straight length below the adpting flange of polymer reactor outlet bend pipe and polymer reactor; Be symmetrically welded with four support tubes or dunnage on this stiffening plate, the upper strata disk that 10-15mm place newly is provided with below it is on lower floor's disk by disk biteplate installation bearing or self-control ball support; Lower floor's disk is fixed on the ground by disk supporting post, the ground fixed disc that is welded on its bottom; Feed bin side pipe line short circuit adpting flange inboard on polymer reactor outlet bend pipe newly is provided with the bend pipe conduit saddle; This conduit saddle below is welded on the pulley spindle by conduit saddle supporting traverse, conduit saddle supporting traverse supporting post, and the pulley of pulley spindle both sides snaps onto in the circular arc slideway.
The utility model has following obvious improvement and positive effect compared with the prior art:
(1) only needs less maintainer's operation,, only need to remove two ends adpting flange bolt, just can realize the quick switching of bend pipe between two feed bin pipelines by rotation without hoist crane.
(2) maintenance can reduce 1/3-1/2 from the member, obviously alleviates labor intensity of operating personnel.
(3), be on lower floor's disk by disk biteplate installation bearing or self-control ball support owing to the new addition of the utility model upper strata disk; Lower floor's disk is fixed on the ground by disk supporting post, the ground fixed disc that is welded on its bottom.Disk rotates on one, and two have had firm new support.Feed bin side pipe line short circuit adpting flange inboard on polymer reactor outlet bend pipe newly is provided with the bend pipe conduit saddle; This conduit saddle below is welded on the pulley spindle by conduit saddle supporting traverse, conduit saddle supporting traverse supporting post, the pulley of pulley spindle both sides snaps onto in the circular arc slideway, from and increased new support, make that pipeline does not shake in the discharging process, realize switching long-period stable operation fast.

Embodiment
Now the utility model is further specified as follows by embodiment and accompanying drawing;
See Fig. 1, Fig. 2, Fig. 3, Fig. 4, reactor outlet bend pipe rotary support mechanism at polymer reactor 5 outlet bend pipes 16, and welds stiffening plate on the adpting flange 17 below straight lengths of polymer reactor 16; Be symmetrically welded four support tubes or dunnage 1 (as Fig. 2) on this stiffening plate, bearing or self-control ball support 2 that the upper strata disk 4 that 10-15mm place newly is provided with below it is installed by disk biteplate 3 are in (see figure 3) on lower floor's disk 6; Lower floor's disk is fixed to (see figure 1) on the ground by disk supporting post 7 and the ground fixed disc 8 that is welded on its bottom; The radius of last lower disc must not be less than the length of the support tube 1 of welding on the outlet bend pipe 16, and feed bin side pipe line short circuit adpting flange 15 inboards on the outlet bend pipe 16 newly are provided with bend pipe conduit saddle 9; This conduit saddle below is welded on the pulley spindle 13 by conduit saddle supporting traverse 10 and conduit saddle supporting traverse supporting post 11; The pulley 12 of pulley spindle 13 both sides snaps onto in the circular arc slideway 14; Whole sliding trace be as the criterion (seeing Fig. 1, Fig. 2, Fig. 4) when the radius of circular arc slideway 14 switches with polymer reactor outlet bend pipe 16.
The utility model reactor outlet bend pipe rotary support mechanism, when polymer reactor outlet connection feed bin need switch, disconnect the short circuit between polymer reactor outlet bend pipe and the feed bin pipeline earlier, remove the bolt on the adpting flange between polymer reactor and the polymer reactor outlet bend pipe, the support tube that welds on the bend pipe is fallen on the disk of rotatable upper strata naturally.At this moment, the reactor outlet bend pipe supports by the bend pipe conduit saddle that upper strata disk, feed bin pipeline side adpting flange side have pulley, and operator only need promote bend pipe, and the feed bin end is moved to be switched feed bin direction, and bend pipe is supported on the disk of upper strata; The upper strata disk rotates on lower floor's disk by bearing or ball support; Have pulley under the bend pipe conduit saddle of pulley in the acting in conjunction of the rolling of circular arc slideway, polymer reactor outlet bend pipe is turned to more easily will connect feed bin one side pipe line place.
