The utility model content
The purpose of this utility model provides a kind of polymerisation agitator, makes that it is easy for installation, the accuracy of manufacture is high.
The purpose of this utility model is achieved in that a kind of polymerisation agitator, the housing and the interior rotor that arranges of housing that comprise horizontal setting, described rotor comprises preceding shaft and the back shaft that arranges on the same horizontal axis, preceding shaft stretches out outside the housing and driving mechanism is in transmission connection, and back shaft is rotatably supported in the housing; Shaft links to each other with preceding card before described, back shaft links to each other with the back card, preceding card parallels setting with the back card and periphery between the two links to each other through some gussets, described gusset is outer and be coated with the cylindrical shell that plate is rolled between preceding card and back card, and described cylindrical shell is provided with some cylindrical shell through holes.
During the utility model work, in housing, charge into the liquid charging stock of polymerisation, by vacuum suction device housing is vacuumized, can in time take the gaseous by-product that reactive evaporation goes out away, when rotor rotates, reaction mass forms big evaporating surface at cylindrical shell and inner barrel, promotes separating out and evaporating of byproduct of reaction, promotes that polymerisation continues to carry out.Compared with prior art, the beneficial effects of the utility model are: this device is easy for installation, the accuracy of manufacture is high, has overcome the defective of welding deformation in the prior art, has improved and has installed and change efficient.This device can be used in the production of polymer such as PET, PBT, PBS, PTT.
For alleviating rotor weight, described through hole is be array distribution tri-angle-holed.Triangle has stable structure, under the prerequisite that guarantees cylindrical shell rigidity, can accomplish that weight is the lightest.
For slowing down material flowing in cylindrical shell, be arranged with some discs in parallel in the cylindrical shell between described preceding card and the back card, described disc is provided with some disc through holes, and the disc center is provided with flow area greater than the central passage of disc through hole.The setting of central through hole can guarantee that inner barrel has enough big gas-phase space.
As further improvement of the utility model, the arrangement pitches of described disc from cylindrical shell one end to the cylindrical shell other end becomes big gradually.When material from one end to the other side flowed in housing, it is big that its viscosity also becomes gradually, by changing the disc spacing, guarantees that material has enough flowabilities, in order to produce continuously.
For ease of disc is installed, described disc periphery is provided with draw-in groove, and draw-in groove correspondence one by one is connected on the described gusset.
As further improvement of the utility model, described cylindrical shell periphery is provided with outer scraper.The setting of outer scraper can scrape off the material that sticks on the inner walls, forms new evaporating surface, promotes reaction to develop to direction of polymerization.
