For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of scrapper thin film evaporator, comprise evaporation cylindrical shell and be arranged on the mainshaft mechanism evaporating body centre axis place, mainshaft mechanism is fixed with the elastic connection plate along mainshaft mechanism circumference uniform distribution, elastic connection plate end is also fixed with and the scraper plate evaporating cylinder inboard wall and contact, described elastic connection plate is superposed by multi-disc stainless steel shell fragment and is fixed and formed, laminating elastic connection plate side has been bolted backplate, and backplate end is bolted on mainshaft mechanism.
The further improvement of technical solutions of the utility model is: described mainshaft mechanism comprises the central shaft running through evaporation cylindrical shell and the bindiny mechanism arranged on center shaft that are arranged on evaporation body centre, described bindiny mechanism comprises being socketed in and is connected and fixed cylinder on center shaft by key outside central shaft, cylinder is outside equipped with connecting axle that is uniform along cylindrical barrel direction, that be arranged in parallel with cylinder, be connected by crossbeam between connecting axle with cylinder, between two adjacent connecting axles, crossbeam is set.
The further improvement of technical solutions of the utility model is: on described central shaft, centrally axle axis direction fixes 6 bindiny mechanisms from top to bottom, described each bindiny mechanism comprises 4 connecting axles, and every root connecting axle top and bottom connect an elastic connection plate.
The further improvement of technical solutions of the utility model is: described elastic connection plate cross section is arcuate structure, and bending direction and the mainshaft mechanism of arcuate structure turn to contrary.
Owing to have employed technique scheme, the technological progress that the utility model obtains is:
This use is novel by arranging an elastic connection plate between scraper plate and main shaft, and scraper plate is close on evaporation cylinder inboard wall, enhances the effect of evaporation, expands the scrapper thin film evaporator scope of application.
Elastic connection plate superposes fixing formation by multi-disc stainless steel shell fragment, enhances the elasticity of elastic connection plate, better play elastic connection plate from tensioning function, on the inwall that scraper plate can be made to be close to evaporate cylindrical shell; Elastic connection plate installs backplate additional, strengthened the rigidity of elastic connection plate, compensate for the defect that cannot be applicable to high-viscosity material that rigidity deficiency is brought.
Scraper plate is close on evaporation cylinder inboard wall, and scraper plate contacts with cylindrical shell, improves heat transfer efficiency, enhances the effect of evaporation; Simultaneously scraper plate can reject the fouling on evaporation cylinder inboard wall the moment, the utility model is not only applicable to material that high-viscosity material is also applicable to easy fouling.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further details:
As shown in Figure 1, the utility model comprises evaporation cylindrical shell 1, and evaporation cylindrical shell 1 is outside equipped with chuck 8, and the central axis of evaporation cylindrical shell 1 is provided with mainshaft mechanism, having evaporation cylindrical shell 1 upper end to be provided with electric machine assembly 10 drives mainshaft mechanism to rotate, and evaporation cylindrical shell 1 lower end is provided with low head 9.Mainshaft mechanism is uniform elastic connection plate 2 circumferentially, and elastic connection plate 2 end is also fixed with scraper plate 3, and scraper plate 3 and evaporation cylindrical shell 1 contact internal walls, the side of each elastic connection plate 2 is fixed with backplate 4, and backplate 4 one end is also fixed on mainshaft mechanism.The utility model by arranging elastic connection plate 2 between scraper plate 3 and mainshaft mechanism, and scraper plate 3 is close on evaporation cylindrical shell 1 inwall, enhance the effect of evaporation, the larger and easy fouling material operating mode of viscosity can be applicable to simultaneously, expand the scrapper thin film evaporator scope of application.
Mainshaft mechanism comprise be arranged on evaporation cylindrical shell 1 central axis place central shaft 5 and centrally axle 5 length direction be fixed on the bindiny mechanism on central shaft 5.Central shaft 5 runs through evaporation cylindrical shell 1, and central shaft 5 upper end is connected with electric machine assembly 10, and electric machine assembly 10 can be with central shaft 5 to rotate.The axis direction of bindiny mechanism's centrally axle 5 is provided with 6 groups from top to bottom, any one group damage after can directly replace, without the need to all replacing increase maintenance cost.Bindiny mechanism comprises cylinder 11, and cylinder 11 to be socketed on central shaft 5 excircle and to be connected by key and is fixed together with central shaft 5, can rotate with central shaft 5.Cylinder 11 is outside equipped with along 4 uniform connecting axles 6 of cylinder 11 circumferencial direction, connecting axle 6 and cylinder 11 be arranged in parallel, be connected by crossbeam 7 between connecting axle 6 with cylinder 11, also connected by crossbeam 7 between two adjacent connecting axles 6, the many places of crossbeam 7 use and make mainshaft mechanism structure more stable.Every root connecting axle 6 top and bottom connect an elastic connection plate 2, and elastic connection plate 2 end is also bolted scraper plate 3, scraper plate 3 and the inwall close contact evaporating cylindrical shell 1.Elastic connection plate 2 is superposed by multi-disc stainless steel shell fragment and is fixed together, enhance the elasticity of elastic connection plate 2, better performance elastic connection plate 2 from tensioning function, scraper plate 3 can be made to be close on the inwall of evaporation cylindrical shell, scraper plate contacts with cylindrical shell, improve heat transfer efficiency, enhance the effect of evaporation; Scraper plate 3 is close on the inwall of evaporation cylindrical shell 1 simultaneously, can reject the fouling on evaporation cylindrical shell 1 inwall the moment, be applicable to the working condition under easy fouling material completely.Elastic connection plate 2 cross section is arcuate structure, and bending direction and the mainshaft mechanism of arcuate structure turn to contrary.
One end of backplate 4 and elastic connection plate 2 are together fixed on connecting axle 6, laminating elastic connection plate 2 side, backplate 4 side is also fixed together by bolt and elastic connection plate 2, strengthen the rigidity of elastic connection plate 2, if do not install backplate 4 additional, full-bodied material is bonded on the inwall of evaporation cylindrical shell 1, only be provided with elastic connection plate 2, elastic connection plate 2 provides enough rigidity to be got off by the material scraper that evaporation cylindrical shell 1 inwall is adhered can not to scraper plate 3; Arrange cylinder 11 outside central shaft 5, cylinder 11 is outer to be connected with connecting axle 6 by crossbeam 7 again, connecting axle 6 is fixed elastic connection plate 2, and the so greatly less length of elastic connection plate 2, enhances the rigidity of elastic connection plate 2; Two kinds of modes compensate for the not enough defect that cannot be applicable to high-viscosity material brought of rigidity.
