Auxiliary seal constitutes axial seal frequently with auxiliary seal ring and material filling type sealing in rotary joint structure, auxiliary
Helping be sealed with that seal ring of moving ring and stationary ring sealing ring rotate together with hollow shaft is ring seal, otherwise belongs to stationary ring sealing, leads to
The shell in hole and the shaft of insertion through-hole, connecting plate are connected with the right side of excess axle, and shaft is fixedly connected with connecting plate, shell
Inner wall be equipped with several annular media slots, be provided with pipe interface on the outer wall of shell, pipe interface is connected to third with media slot
Medium channel is arranged in shaft, and perforation is also connect in shaft and is connected to third medium channel with corresponding media slot, on shell
An inner seal structure is equipped between every two adjacent media slot.
Existing market mainstream rotary joint is divided into filler-sealing type rotary joint and Mechanical Sealed Type rotary joint, mechanical seal
Formula rotary joint structure is compact, and dynamic and static ring mechanical seal is safe and reliable, can compensate automatically after seal wears, due to mechanical seal
It rubs larger, with the attrition of sealing ring, drainage is more obvious, and replaces more frequent, filler-sealing type rotation
Adapter passes through close carbon fiber filler between sealing shroud and shell, and lubrication is insufficient, and carrying pressure is larger, and generates mill
Damage consumption so that be association of activity and inertia and locate gap increase, cause poor sealing performance, and the service life is short.
Utility model content
Lag cooler can be revolved using the method for helixseal the technical problem to be solved by the present invention is to provide a kind of
The device that adapter is sealed.
The technical solution adopted in the utility model is in order to solve the above problem:
A kind of sealing device of lag cooler rotary joint, including rotation core pipe and the sealing being arranged in rotation core pipe
Set, the rotation core pipe are welded by inner sleeve and outer tube suit, and sealing shroud, institute are arranged on the tube wall of the outer tube
One section of outer rectangular thread ring of setting on the outer tube wall of outer tube is stated, interior rectangle screwed ring, institute are set on the inner wall of the sealing shroud
The interior rectangle screwed ring gap of the outer rectangular thread ring for stating outer tube and the sealing shroud is staggeredly equipped with, the outer rectangle spiral shell
Line ring and the gap location of the interior rectangle screwed ring are equipped with sealing material, and fixed device is arranged in the sealing shroud.
Preferably, the sealing shroud is flange sleeve made of being fastened as upper and lower two parts semicircle external member, the semicircle
The commissure of external member is by being welded and fixed.
Preferably, the fixed device is arranged in sealing shroud rear end, including the ring flange being installed on the outer tube, institute
Ring flange is stated to be spirally connected with the flange sleeve.
Preferably, the material of the inner sleeve and outer tube is stainless steel.
Preferably, the sealing material is lubricating grease.
The utility model has the advantages that the utility model makes the rotation core pipe of rotation and fixed sealing shroud pass through square by helixseal
The anti-motive force of shape screwed ring pushes the liquid of flowing to shell, is unlikely to leak outside；The inner sleeve that liquid medium passes through rotation core pipe
After pipe enters cold slag machine drum body circulation, through rotation core pipe outer tube outflow, the rotation of core pipe and being association of activity and inertia for sealing shroud are rotated
The leakage that liquid medium is prevented under the direction impetus that place is sealed by inside and outside rectangular thread ring, between outer tube and sealing shroud
Lubricating grease is arranged at gap can effectively increase lubricity, reduce carrying pressure.
