Description
Technical field
The utility model provides the polymeric kettle that is used for chemosynthesis of chemical machinery field, specifically pvc polymerizer.
Background technology
Before the utility model proposes, pvc polymerizer is made of kettle, agitator and loading, unloading material mouth.Kettle is provided with tabular watercooling jacket, is used for the thermal exchange of polyvinyl chloride polymerization process, guarantees polymeric reaction temperature.On stir shaft, be provided with the straight-plate-type agitating vane, be used for the stirring of polymkeric substance, guarantee the abundant contact of reaction mass, polyreaction is carried out.Stir shaft is installed on the power motor in the kettle outside, is used to provide stirring power.Stir shaft is the solid metal body.The flow deflector of entity is housed, the water conservancy diversion of material when being used to stir in kettle.
The shortcoming that existing pvc polymerizer exists is:
1. temperature condition required when the polyvinyl chloride material carries out polyreaction in polymeric kettle is finished by the water jacket that is located on the kettle merely, and the thermal conduction contact area is little, and conduction efficiency is low, and polymerization reaction time is long.
2. the blade of agitator is straight plate structure, and the agitating vane contact area is little, and Flow of Goods and Materials efficient is low, and speed of response is slow.
3. the flow deflector of entity can play the effect to the water conservancy diversion of material, but adjusting does not have positive effect to material temperature.
Summary of the invention
In order to overcome the shortcoming of existing pvc response still, the utility model proposes a kind of pvc polymerizer of new texture.Its technical scheme is: pillar, end baiting valve, opening for feed, spray valve, thermo detector, human body gangway and human body discrepancy flap are installed on the kettle of pvc polymerizer.Its top is equipped with frame, and step-down gear is installed on frame, and agitator motor is installed on step-down gear.Bottom at step-down gear is connected with stir shaft, and the stir shaft upper end is connected with step-down gear, and the lower end is installed on the base bearing that is provided with water injection hole, and the swept-back agitating vane is installed on stir shaft.Be provided with the semicircle pipe clamp cover of helical arrangement in the kettle outside and be connected with water inlet pipe and rising pipe.Cold apron in the sleeve pipe is installed on the kettle diapire.Between kettle wall in frame and the stir shaft mechanical seal parts are installed.Inner wall of kettle is provided with the electropolishing layer.
Advantage of the present utility model is as follows:
1, good heat-transfer.Because the utility model constitutes heat-transfer system, its good heat-transfer by cold apron in kettle, semicircle pipe clamp cover and the sleeve pipe.Heat-transfer capability is the key technical index that influences polyvinyl chloride product output and quality, and the watercooling jacket of existing polymeric kettle and the gap between the flow deflector are difficult to control, the large and small direct heat transfer efficiency that influences in its gap.Yet the utility model has adopted semicircle pipe clamp nested structure, has stopped the short circuit phenomenon of current, has improved total heat transfer efficiency.Interior cold apron is a sleeve structure, and the heat transfer efficiency height helps improving the heat transmission of the material of polymeric kettle inside, guarantees that temperature of reaction moves in the best condition.Because cold apron is installed in the bottom of kettle in the sleeve pipe, help dismounting and to the polished finish of kettle.
2, stirring efficiency height.Because the utility model adopts the swept-back agitating vane of swept-back structure formation, compare with the straight-plate-type agitating vane, running resistance is little, to stirring of material, reaction mass can fully be contacted and stir, help improving polymerization rate and level of response.
3, good seal performance.Because the utility model adopts the structure formation of mechanical seal, compare with the sealing means of sealing-ring, good airproof performance, sealing part abrasion is little, long service life, consumed power is low.
4, whipped state is stable.Because stir shaft of the present utility model lower end is installed on the base bearing, help the stable of stir shaft.And can realize water filling in polymeric kettle at water injection hole set on the base bearing, play cooling effect simultaneously to base bearing and stir shaft.
5,, can prevent material bonding still wall because inner wall of kettle is provided with the electropolishing layer.
Owing to the utlity model has high-performance as above, to compare with isometric reactor, its throughput can improve more than 12%.
