Background technology
The effect of centrifugal-film evaporator is to become uniform liquid film to evaporate liquid distribution or concentrate, and is widely used in industries such as Chinese and Western medicine, food, light industry, oil, chemical industry and environmental protection.Chinese patent Granted publication CN201067641Y discloses a kind of centrifugal-film evaporator, the achievement part of this patent application technical scheme is: spacer and main shaft are connect, making spacer take evaporation body rotates with main shaft, thereby the evaporation time of material on evaporation body shortened and make liquid film even, thereby help to improve evaporation efficiency and effect, and can also energy savings.In this patent application, give charging/discharging device, this charging/discharging device is by shown in Figure 1, comprise material inlet tube 1 and concentrate fairlead 2, during use, to need the material of evaporation process to be incorporated into being shaped as on the undulatory evaporating surface 31 of evaporation body 3 of centrifugal-film evaporator by material inlet tube 1,32 pairs of evaporating surfaces of vapor chamber, 31 evaporations by evaporation body 3, the condensate liquid that produces in the evaporation process is drawn by condensate liquid drain pipe 33, and the resulting concentrate in evaporation back is drawn by concentrate fairlead 2 negative pressure.
The existing shortcoming of the charging/discharging device of the centrifugal-film evaporator of said structure is: the uniformity that is incorporated into the material on the evaporating surface 31 of evaporation body 3 by material inlet tube 1 is relatively poor, that is to say, material inlet tube 1 can't be distributed to material the surface of the evaporating surface 31 of evaporation body 3 equably, thereby influence evaporation efficiency and effect, and be not enough to embody energy-conservation (saving steam); The structure of concentrate fairlead 2 is lost rationally, is unfavorable for drawing fast of concentrate, and if concentrate is drawn fast, then must increase negative pressure, thereby causes the energy resource consumption of vacuum plant big.Based on said circumstances, be necessary charging/discharging device is done rationally to improve, technical scheme described below produces under this background.
Summary of the invention
Task of the present utility model is to provide a kind of evaporating surface that can make material be distributed to evaporation body equably to get on and uses and improve evaporation efficiency and effect and embody energy-conservationly, the resulting concentrate in evaporation back can be drawn and helped reducing the charging/discharging device of the centrifugal-film evaporator of negative pressure again fast.
Task of the present utility model is finished like this, a kind of charging/discharging device of centrifugal-film evaporator, it comprises that one is stretched over being used in the evaporation body of centrifugal-film evaporator material is incorporated into the material fairlead that being used in the evaporation body that material inlet tube and that the evaporating surface of evaporation body gets on similarly is stretched over centrifugal-film evaporator will the resulting concentrate in evaporation back draw, described material inlet tube is equipped with a material in the end that is positioned at described evaporation body and divides sheet, this material divides the navel plate of sheet and evaporating surface to fix, and divides sheet that the discharging opening of material inlet tube is surrounded by this material; Dispose the diameter suction nozzle bigger than the diameter of concentrate fairlead on the charging aperture of the end of described concentrate fairlead in being stretched over described evaporation body, the suction inlet of this suction nozzle is in alignment with described evaporating surface.
In a specific embodiment of the present utility model, described material divides the truncated cone that is shaped as of sheet.
In another specific embodiment of the present utility model, described material divide sheet towards the end of described navel plate along on extend at least more than one hanging feet, hanging feet and described navel plate fix, and constitute one between the adjacent hanging feet and be used for material is distributed to the cloth seam that evaporating surface gets on.
Go back in the specific embodiment shape flare of described suction nozzle of the present utility model.
In another specific embodiment of the present utility model, the reverse aligning evaporating surface of described suction nozzle.
In another specific embodiment of the present utility model, described reverse aligning evaporating surface is meant opposite with the direction of rotation of evaporating surface.
Therefore the utility model can be distributed to material on the evaporating surface equably owing to set up material divide sheet outside the material inlet tube, thereby helps improving evaporation efficiency and effect and can also economize in the steam of evaporation; Owing on the concentrate fairlead, set up suction nozzle, helped concentrate is drawn, and can reduce the negative pressure of vacuum plant.
Description of drawings
Fig. 1 is the schematic diagram of the charging/discharging device of the centrifugal-film evaporator in the prior art.
Fig. 2 is the first enforcement illustration of the present utility model.
Fig. 3 is the second enforcement illustration of the present utility model.
The specific embodiment
Embodiment 1:
Ask for an interview Fig. 2, the end with discharging opening 11 of material inlet tube 1 extend in the evaporating surface 31 of evaporation body 3, and is close to navel plate 311 places of evaporating surface 31.Add at the pipe end of the material inlet tube 1 of the evaporating surface 31 that is positioned at evaporation body 3 and to be located at a material and to divide sheet 12, divide sheet 12 that the discharging opening 11 of material inlet tube 1 is surrounded by this material that is shaped as the frustum of a cone, material divide 12 of sheets towards the end of navel plate 311 along on equidistantly to be distributed with three hanging feets 121, each hanging feet 121 is fixing with navel plate 311, and constitute cloth seam 1211 between the adjacent hanging feet 121, the material that comes from discharging opening 11 is drawn out on the evaporating surface 31 by cloth seam 1211, because down, evaporation body 3 rotates the centrifugal thin-film separator in working order.Hence one can see that, and compared with the prior art drawing of material have good homogeneous, can improve the evaporation efficiency and the effect of 32 pairs of evaporating surfaces 31 of evaporation cavity, and the condensate liquid that results from the evaporation process in the evaporation cavity 32 is drawn by condensate liquid drain pipe 33.
Embodiment 2:
Ask for an interview Fig. 3, an end of the material fairlead 2 that the concentrate after being used for evaporation finished is drawn extend into evaporating surface 31, connects the diameter suction nozzle 21 bigger than the caliber of material fairlead 2 at the charging aperture position of this material fairlead 2.In the present embodiment, suction nozzle 21 is designed to tubaeform, the suction inlet of suction nozzle 21 211 is aimed at evaporating surfaces 31, and more particularly the top with evaporating surface 31 aligns, and is opposite with the direction of rotation of evaporation body 3.Compared with the prior art this design has desirable discharging effect, this effect is embodied in as long as (prior art is-0.9MPa under better than nothing negative pressure, and the utility model only just can smooth and easy discharging for-0.2MPa) just can draw concentrate is smooth and easy, because, when evaporation body 3 when rotated, make concentrate produce centrifugal pressure, therefore can reduce the degree that vacuumizes of vacuum plant, promptly embody energy savings by the power that reduces vacuum plant.
Because the operation principle of centrifugal-film evaporator belongs to prior art, the existing detailed description in detail among the CN201067641Y for example above-mentioned, so the applicant no longer narrates.Need to prove: charging/discharging device of the present utility model is not limited to be configured on the centrifugal-film evaporator of structure shown in the CN201067641Y.
