Brief description of the drawings
The above and other features of the present invention, property and advantage will be become readily apparent from by description with reference to the accompanying drawings and examples, wherein：
Fig. 1 is the structural representation of the online high viscosity powder system of one embodiment of the invention.
Embodiment
With reference to specific embodiments and the drawings, the invention will be further described; more details are elaborated in the following description in order to fully understand the present invention; but the present invention obviously can be implemented with a variety of other manners different from this description; those skilled in the art can make similar popularization according to practical situations in the case of without prejudice to intension of the present invention, deduce, therefore should not be limited the scope of the invention with the content of this specific embodiment.
Fig. 1 is the schematic flow sheet of the online high viscosity powder system of invention one embodiment.As illustrated, the online high viscosity powder system 300 includes：The feed bin 301 for containing non-metallic powder, the first pipe arrangement 4, the second pipe arrangement 5, the self priming pump 303 and homogenizer 304 for producing vacuum are provided, the first control valve 306 is provided with the first pipe arrangement 4, the second control valve 302 is provided with the second pipe arrangement 5.Feed bin 301 is connected to the second pipe arrangement 5 by the first pipe arrangement 4.Second pipe arrangement 5 is connected to the entrance of self priming pump 303.The outlet of self priming pump 303 is connected with the entrance of homogenizer 304, and homogenizer 304 exports after its working chamber 305 is interior by non-metallic powder and high viscosity liquid dispersion mixing.
First control valve 306, the second control valve 302 can be multiposition dish valves.First control valve 306 can be understood as with the outlet of feed bin 301 and the entrance of self priming pump 303 being connected respectively, for controlling the lower powder speed of non-metallic powder, prevent due to lower powder is too fast and block self-pumping pump 303.
With continued reference to Fig. 1, the section between the entrance of the junction of the first pipe arrangement 4 and the second pipe arrangement 5 to self priming pump 303 is provided with pressure gauge 307.When high viscosity liquid flows through self priming pump 303, the rotation of self priming pump 303 generates vacuum, and the aperture of the second control valve 302 is adjusted by observing the size of the pressure value on pressure gauge 307.When pressure tabular value is big, the aperture of multiposition butterfly valve 302 is tuned up, when pressure tabular value is small, turns the aperture of multiposition butterfly valve 302 down, pressure value is maintained at the value of a setting.Regulation therein can be automatically adjusted by automatic control system, can also be adjusted manually.
Pipeline viewing mirror 308 can be included between self priming pump 303 and homogenizer 304, for monitoring self priming pump 3 and exporting putty situation whether occurs.
The process that dispersion mixing is carried out to non-metallic powder and high viscosity liquid using above-mentioned online high viscosity powder system 300 can be described as follows：
Powder is previously charged into feed bin 301, now powder valve 306 is to close.Then the flow of liquid to be mixed is set, starts self priming pump 303 and homogenizer 304 successively.When vacuum reaches the lower powder value of requirement, the first control valve 306 opened on feed bin 301 starts lower powder.Powder by the control valve 302 of self priming pump 303 and second work in coordination caused by negative pressure of vacuum and/or powder deadweight suction self priming pump 303 in, and homogenizer 304 is transported to together with high viscosity liquid, by powder and the dispersed mixing of liquid in the working chamber 310 of homogenizer 304.If during mixed powder, vacuum is higher or lower than setting value, then closes the first control valve 306 and stop lower powder, opened again after waiting vacuum values normal.After being mixed etc. all powders and liquid, stop self priming pump 302 and homogenizer 304.
Previous embodiment works in coordination to form negative pressure using self priming pump and adjusting control valve, simultaneously by the deadweight and/or negative pressure of non-metallic powder so that powder to be suctioned out from feed bin, with being transported to homogenizer together with liquid, will be exported in the working chamber of homogenizer after powder and the dispersed mixing of liquid.Whole process suction powder speed is fast, and the mixed powder time is short, does not produce airborne dust and bubble, does not increase extra processing step, save energy consumption, improves the efficiency of mixed powder, optimize production technology.
