Background technology
The material that thinfilm rotary evaporator relates generally to industries such as petrochemical industry, pharmacy and food processing concentrates, evaporation, rectifying, precipitation; Its heat transfer coefficient is big, evaporation intensity is high, the overcurrent time is short, operating flexibility is big, obtains extensive use in industries such as chemical industry, petrochemical industry, medicine, agricultural chemicals, daily use chemicals, food, fine chemistry industries.In the prior art, thinfilm rotary evaporator comprises that mainly main shaft, the rotation rubbing board device and chuck, cylindrical shell, last low head and the motor etc. that are driven by main shaft constitute.In thinfilm rotary evaporator, screeding device is a key device of this equipment, and material is forced film forming by rotor segment on the evaporimeter barrel in the access arrangement separation process, and then be implemented in the course of work of carrying out falling film evaporation under the vacuum condition.Therefore whether the version of this screeding device adapts to technological requirement becomes the normal key factor of running continuously of equipment.
According to the requirement of technology, present scraper plate form mainly contains four kinds, promptly movable scraper plate, hinge type scraper plate, fixed scraper plate and helical flight.Movable scraper plate is the most basic, the modal a kind of scraper plate form: scraper plate is installed in four scraper plate guide grooves of rotor, radially gets rid of to evaporation cylindrical shell internal face owing to be subjected to the centrifugal action of rotor rotation, makes circular motion with rotor simultaneously.This of scraper plate scrapes, and makes material be membranaceous turbulence state in evaporation on the wall, greatly improved heat transfer coefficient, simultaneously thisly continuously scrapes, and suppresses phenomenons such as overheated, the dried wall of material and fouling effectively.Fixed scraper plate and helical flight all adopt metal material, it is rigidly attached on the rotor, the length of scraper plate is with the evaporation stack shell, rotor segment only is 1-2mm with the gap of evaporation stack shell inwall, processing of having relatively high expectations and installation accuracy, evaporation and concentration, precipitation or the purification of its suitable extra-high-speed viscosity and the material that easily spumes.The hinge type scraper plate is suitable for the easily material of fouling on heating surface, and scraper plate adopts nonmetal parts usually, adopts the hinges mode that scraper plate is installed on the pivoted frame.When rotor rotation, because action of centrifugal force, scraper plate is pressed on the evaporation cylinder inboard wall, and (with wall) slides at wall at an angle, material spread to film, and prevent the wall fouling.Elastic scraper then utilizes the principle of spring to make scraper plate pack into behind the main cylinder, just fits together with the main cylinder inner surface, is particularly suitable for the bigger material of viscosity.In the past, for the bigger material of viscosity, have only and select fixedly scraper plate, and fixedly scraper plate can not contact with the main cylinder inner surface, and certain clearance is arranged between them all the time, had reduced evaporation effect to a certain extent.The spring scraper plate has just in time remedied this point.Therefore the spring scraper plate will have very big space in high viscosity material evaporation field.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of thinfilm rotary evaporator, scraper plate is contacted fully fully with inner tube wall, can play the effect of augmentation of heat transfer, and can finish evaporation process at a high speed, efficiently, reliably, can effectively reduce cost, and can improve the service life of complete machine.
The technical scheme that provides according to the utility model, comprise rotor crossbeam, main shaft, evaporation cylindrical shell, chuck, go up low head and electric machine assembly, described chuck is arranged in the evaporation cylindrical shell, in the evaporation cylindrical shell, main shaft is installed, main shaft is provided with the rotor crossbeam of plurality of fixed, described evaporation cylindrical shell upper and lower side is installed low head respectively, electric machine assembly is installed in evaporation cylindrical shell upper end, feature is: described rotor crossbeam connects gripper shoe, gripper shoe is connected with elastic plate one end by securing member, and an other end of elastic plate is connected with rotor segment by securing member.
Described rotor segment is close on the evaporation cylindrical shell internal face.Described gripper shoe is connected the position that can be used for regulating elastic plate, rotor segment and evaporation cylinder inboard wall with the rotor crossbeam.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Owing to use the elastic scraper device, can make to rotate to draw together to pull under the high viscosity material and fit with the evaporation cylinder inner surface, because contact fully fully, can play the effect of augmentation of heat transfer, and can be at a high speed, finish evaporation process efficiently, reliably, be applicable to the working condition of thinfilm rotary evaporator under the high viscosity material fully.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is elastic scraper apparatus structure schematic diagram in the utility model evaporation cylindrical shell.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1-shown in Figure 2, comprise elastic plate 1, rotor segment 2, securing member 3, securing member 4, gripper shoe 5, rotor crossbeam 6, main shaft 7, evaporation cylindrical shell 8, chuck 9, go up low head 10 and electric machine assembly 11 etc.
The utility model adopts chuck 9 to be arranged in the evaporation cylindrical shell 8, in evaporation cylindrical shell 8 main shaft 7 is installed, and main shaft 7 is provided with the rotor crossbeam 6 of plurality of fixed, and rotor crossbeam 6 is formed by 4 groups or 4 groups usually at circumferencial direction.Described evaporation cylindrical shell 8 upper and lower sides are installed low head 10 respectively, and electric machine assembly 11 is installed in evaporation cylindrical shell 8 upper ends, and described rotor crossbeam 6 is connected with the elastic scraper device.The elastic scraper device comprises elastic plate 1, rotor segment 2, securing member screw 3, securing member screw 4 and gripper shoe 5 compositions.Gripper shoe 5 is connected with elastic plate 1 one ends by securing member screw 4, and an other end of elastic plate 1 is connected with rotor segment 2 by securing member 3 screws.Described gripper shoe 5 can adjusting position with being connected of rotor crossbeam 6.Described elastic plate 1 adopts the metallic elastic material to make.
After assembling was finished, the locus circle diameter D of rotor segment 2 ends was slightly larger than the interior diameter of evaporation cylindrical shell 8 inwalls under free state.After rotor crossbeam 6 was packed evaporation cylindrical shell 8 into, rotor segment 2 will be close under the effect of elastic plate 1 on evaporation cylindrical shell 8 internal faces like this.This elastic scraper device elastic plate can make scraper plate contact fully fully with inner tube wall, is applicable to the working condition of thinfilm rotary evaporator under the high viscosity material fully.
Because the regulating action of elastic plate, can make the rotation rubbing board and the gap of evaporation cylinder inboard wall reach minimum, compare with installation accuracy with the processing that traditional fixedly scraper plate is had relatively high expectations to cylindrical shell and rotor, effectively reduce production cost, simultaneously, because the rotation rubbing board is that a kind of flexibility contacts with the evaporation cylinder inboard wall, fault rate is low, can effectively improve the service life of complete machine.
