Description

Chlorinated polyethylene reation kettle in time observes glass-lined repair subassembly of leaking

Technical Field

The utility model relates to a chlorinated polyethylene preparation technical field especially relates to a chlorinated polyethylene reation kettle in time observes glass that wards off of leaking and repairs subassembly.

Background

The general repairing method of the existing chlorinated polyethylene reaction kettle after glass lining is damaged is that two repairing conditions of penetration and non-penetration are divided according to the corrosion degree of a steel matrix. Under the condition that the cylinder body does not penetrate, drilling and tapping are generally adopted in a kettle to damage a small area, and a repairing part is fastened on the kettle body through a corrosion-resistant bolt. The repair of large-area damaged areas, which basically penetrate through the kettle wall, particularly in the case of perforation, adopts a method of fastening the damaged areas by bolts from the outside.

The problem with the current technology is that even experienced service personnel often check the fastening. However, the progress of the repair cannot be known, and the early repair failure of the repair point cannot be found in time. So that the damaged point is expanded when the condition of the repaired point is found again. Even the glass lining kettle can not be repaired again, and the scrapped degree of the glass lining kettle can be directly reached. Because the glass lining reaction kettle is internally provided with extremely toxic chlorine and high-temperature hydrochloric acid with strong corrosiveness, serious safety and environmental protection accidents can be caused under the condition of serious penetration, and huge loss can be caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving prior art, the chlorinated polyethylene reation kettle that provides in time observes lining glass of leakage and repairs subassembly, to the creep that the long-term high temperature operation of polytetrafluoroethylene gasket leads to, the defect that sealing performance variation became invalid just in time discovers in early stage, and the high temperature hydrochloric acid and the virulent chlorine of seepage can flow out in the observation hole of leaking, just can follow the outside and just in time discover the sealed inefficacy condition of mending in the cauldron. Thereby preventing the damage from expanding to be irretrievable until the reaction kettle is scrapped.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a chlorinated polyethylene reation kettle in time observes glass-lined of leaking and repairs subassembly, includes: a tie bolt, anti-corrosion repair plate, butterfly spring and lock nut for fixing barrel damaged area department in reation kettle, wherein: the utility model discloses a set up the reation kettle, including anticorrosive repair plate, take-up bolt, supporting sleeve, butterfly spring and lock nut, the anticorrosive repair plate is located the inboard of the internal barrel of reation kettle, fixed take-up bolt on the anticorrosive repair plate, take-up bolt passes the internal barrel of reation kettle and extends to the external cover of reation kettle, take-up bolt's outside cover has supporting sleeve, the last observation hole that is equipped with of supporting sleeve, supporting sleeve's outside is equipped with presss from both sides cover isolation sleeve, take-up bolt's end fixing butterfly spring and lock nut.

Preferably, a polytetrafluoroethylene gasket is arranged between the corrosion-resistant repair plate and the inner cylinder of the reaction kettle body, and the polytetrafluoroethylene gasket is sleeved on the tension bolt.

It is further preferred that the corrosion resistant repair plate has a diameter 55-65mm larger than the damaged area.

Further preferably, the polytetrafluoroethylene gasket has a size and an outer diameter consistent with the diameter of the corrosion-resistant repair plate.

Preferably, one end of the jacket isolation sleeve is welded with the outer wall of the inner cylinder of the reaction kettle, and the other end of the jacket isolation sleeve is welded with the outer sleeve of the reaction kettle.

Further preferably, the lock nut is located outside the disc spring.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model provides a pair of chlorinated polyethylene reation kettle in time observes glass-lined repair subassembly of leakage, to the creep that the long-term high temperature operation of polytetrafluoroethylene gasket leads to, the defect of sealing performance variation inefficacy just in time discovers in early stage, and the high temperature hydrochloric acid and the virulent chlorine of seepage can flow out to pressing from both sides the cover isolating sleeve from leaking the observation hole, just can follow the outside and just in time discover the sealed inefficacy condition of mending in the cauldron.

2. The utility model provides a pair of chlorinated polyethylene reation kettle in time observes glass-lined repair subassembly of leaking, when the discovery has the leakage, repairs the point and generally can not enlarge, in time changes seal gasket, just can drop into operation. Getting rid of the phenomenon that the problem repair is carried out for several days before.

3. The utility model provides a pair of chlorinated polyethylene reation kettle in time observes warding off glass of leakage and repairs subassembly reduces maintenance cost, avoids the heavy loss.
