The utility model discloses not only replace traditional interpolation chemical defoaming agent's defoaming treatment method, still had advantages such as the defoaming is thorough, easy operation, energy saving and consumption reduction, economic benefits height, product high quality.
Description
Technical field:
This utility model relates to chemical machinery field, is specifically related to a kind of for the dynamic defoaming device in polyvinyl chloride resin production technique.
Background technology:
In the technique producing PVC paste resin, vinyl chloride is recycled in blowpit process system and can take emulsifying agent and the serum that foam includes out of. Therefore, in vinyl chloride removal process, gas-phase space can produce substantial amounts of foam, containing unreacted Vinyl Chloride Monomer, emulsifying agent, serum, thin colloid, initiator etc. in these foams, if these foams follow latex access arrangement pipeline, will blocking pipeline, impact produce be normally carried out. In order to solve this problem, traditional handicraft is to add the chemical method of chemistry defoamer to eliminate foam in vinyl chloride removal process, not only relatively costly, also directly affects the stability of latex and the performance of product.
Summary of the invention:
The purpose of this utility model is to solve the problems referred to above, and a kind of dynamic mechanically defoaming device is provided, instead of traditional defoaming treatment method adding chemistry defoamer, also there is the advantages such as froth breaking is thorough, simple to operate, energy-saving and cost-reducing, high financial profit, product quality are excellent.
The purpose of this utility model is achieved through the following technical solutions: this dynamic defoaming device, including motor, reductor and impeller, described motor is connected with reductor, the output shaft of described reductor is connected with impeller, it is characterized in that: described dynamic defoaming device also designs a metal sleeve, described metal sleeve is placed on outside output shaft and fixes with reductor bottom and is connected, described metal sleeve side is provided with rinse mouth and Vinyl Chloride Monomer floss hole, and the blade of described impeller adopts fan split blade type oblique cone structure.
Preferably, the angle of the blade oblique cone of described impeller is 12 °～45 °.
Preferably, the blade quantity of described impeller is 7～15.
Preferably, the blade of described impeller arranges several spines.
Preferably, the rotating speed of described motor is 350～900rpm.
Compared with prior art, of the present utility model have the beneficial effect that by adopt physics mode in removal process produce containing unreacted Vinyl Chloride Monomer, emulsifying agent, serum, thin colloid, initiator foam carry out defoaming treatment, reclaim the Vinyl Chloride Monomer in gas phase and the thin latex in foam simultaneously, paste resin emulsion after froth breaking is practically free of bubble, groove can be directly entered, and entered drying process by groove. Therefore, this utility model has without chemistry defoamer, the advantage such as froth breaking is thorough, simple to operate, energy-saving and cost-reducing, high financial profit, product quality are excellent.

Detailed description of the invention:
Below in conjunction with the drawings and the specific embodiments, this utility model is described in detail: a kind of defoaming device shown in Fig. 1 to Fig. 3,
Including motor 1, reductor 2 and impeller 7, described motor 1 is connected with reductor 2, the output shaft 6 of described reductor is fixing with impeller 7 to be connected, described dynamic defoaming device also designs a metal sleeve 5, described metal sleeve 5 is placed on outside described output shaft 6 and fixes with reductor 2 bottom and is connected, described metal sleeve 5 side is provided with rinse mouth 4 and Vinyl Chloride Monomer floss hole 3, and the blade 8 of described impeller adopts fan split blade type oblique cone structure.
Another preferred embodiment, is different in that the angle of the oblique cone of described blade 8 is 12 °～45 °.
Another preferred embodiment, is different in that blade 8 quantity of described impeller 7 is 7～15.
Another preferred embodiment, as shown in Figure 4, is different in that on the blade 8 of described impeller 7 and arranges several spines 9.
Another preferred embodiment, is different in that the rotating speed of described motor 1 is 350～900rpm.
During this dynamic defoaming device busy, described motor 1 transfers energy to described output shaft 6 by described reductor 2, and described output shaft 6 drives described impeller 7 to rotate, and described impeller 7 is forming one downward wind-force after rotating about. When the foam that gas-phase space in container produces is gradually increasing, under normal circumstances, reason due to blast, the generation of foam can be suppressed and suppress foam rising, and destroy foam, and when foam generation amount is relatively larger, lather quickness compares faster time, foam rises to described impeller 7 place and will be broken up by the blade 8 in high speed rotating, and the vinyl chloride gas of gas-phase space can export from Vinyl Chloride Monomer floss hole 3 through metal sleeve 5. After froth breaking end-of-job, open rinse mouth 4, impeller 7 is rinsed.
It is emphasized that: be only preferred embodiment of the present utility model above, not this utility model is done any pro forma restriction, every any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model, all still falls within the scope of technical solutions of the utility model.
