Abstract
The invention discloses a kind of discharging not airborne dust vacuum and enter powder method, comprise the following steps: on still, connect vacuum pump；Start in vacuum pump makes still and reach an effective vacuum；Powder to be added is added in the hopper of still；Described hopper is connected by charge pipe with still, and charge pipe is positioned under still liquid level with the connection end of still；Opening the ball valve of hopper and charge pipe junction, under negative pressure of vacuum effect, need the powder added by charge pipe automatically into still, feed and pass through vacuum in vacuum pump holding still, the powder making needs add constantly is inhaled into still, until powder adds.The charging process of the present invention is safe efficient, solves the problem that during addition powder, poisonous and hazardous material distributes, affects environment and personal safety in liquid phase material at present；Meanwhile, after vacuum powder enters liquid phase, needing to experience one and upwards spray the process then landed, dispersion is more uniformly distributed.
Description
Technical field
The present invention relates to a kind of method adding powder in liquid phase material, a kind of discharging not airborne dust vacuum enters powder method specifically.
Background technology
Chemical field, especially base material preparation field, powder often needs to add as important ingredient.And due to the needs of preparation, all or part of powder needs to be added step-wise in subsequent process in liquid phase material, the most conventional way uses bag-breaking type exactly: material bag wraps in and scratched equipped with on the hopper of blade, material is allowed to freely fall in still, this bag-breaking type enters powder method, on the one hand causing dust from flying, endanger workers ' health, some inflammable and explosive dust even can cause blast.On the other hand, the powder kicked up concentrates on kettle cover, and then make moist caking, and caking sheds in still, can affect product quality, further, this enter powder mode, although make it disperse in the liquid phase by stirring after entering powder, but be difficult to be uniformly dispersed.
Summary of the invention
The technical problem to be solved in the present invention is: for solving above-mentioned technical problem, and the present invention proposes a kind of discharging not airborne dust vacuum and enters powder method, and when both having made powder pour out, airborne dust can also not make powder be uniformly dispersed after entering liquid phase.
The present invention solves the solution of its technical problem: a kind of discharging not airborne dust vacuum enters powder method, comprises the following steps:
The still with liquid phase material is connected with vacuum pump；
Start in vacuum pump makes still and reach an effective vacuum；
Powder to be added is added in the hopper of still；Described hopper is connected by charge pipe with still, and charge pipe is positioned under still liquid level with the connection end of still；
Opening the ball valve of hopper and charge pipe junction, under negative pressure of vacuum effect, need the powder added by charge pipe automatically into still, feed and pass through vacuum in vacuum pump holding still, the powder making needs add constantly is inhaled into still, until powder adds.
Preferably, the vacuum in described still is-10～-80kpa.
In order to avoid the liquid phase in still enters charge pipe, it is preferable that described charge pipe enters the subsurface one end of still and has check valve.
Preferably, described charge pipe at least one.In order to make material dispersion evenly, the bar number of pipe can be increased.
The invention has the beneficial effects as follows: the present invention makes the pressure in still be negative pressure by the way of evacuation, powder introduces below still liquid level add, whole process is carried out under condition of negative pressure, feed safe efficient, solve the practical problem with poisonous and hazardous material is dispersed in the environment of surrounding or can splash operator during liquid phase adds powder at present, allow operator be emancipated from hard work, also improve working environment simultaneously.Further, vacuum powder enters after liquid phase, needs to experience one and upwards sprays the process then landed, and the most scattered is more uniformly distributed.The present invention can be used for adding in liquid phase in chemical process powder.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in describing embodiment below, the required accompanying drawing used is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present invention rather than whole embodiment, and those skilled in the art is not on the premise of paying creative work, it is also possible to obtain other designs and accompanying drawing according to these accompanying drawings.
Fig. 1 is the schematic diagram of an embodiment of the present invention.
Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the technique effect of design, concrete structure and the generation of the present invention is carried out clear, complete description, to be completely understood by the purpose of the present invention, feature and effect.Obviously; described embodiment is a part of embodiment of the present invention rather than whole embodiment, based on embodiments of the invention; other embodiments that those skilled in the art is obtained on the premise of not paying creative work, belong to the scope of protection of the invention.It addition, all connection/annexations being previously mentioned in literary composition, the most singly refer to that component directly connects, and refer to couple auxiliary according to being embodied as situation by adding or reducing, form more excellent draw bail.Each technical characteristic in the invention, can be with combination of interactions on the premise of the most conflicting conflict.
The still being previously mentioned in the present invention, is the interior container commonly used of chemical process, is mainly used for the container of material physical mixed or reaction, such as stirred tank, mixing kettle etc..
With reference to Fig. 1, for the embodiment schematic diagram of the method for the present invention, a kind of discharging not airborne dust vacuum enters powder method, specifically:
1) still 1 with liquid phase material is connected with vacuum pump 2；
2) startup vacuum pump 2 reaches an effective vacuum in making still 1；Preferably, vacuum is-10 ~-80Kpa；
3) in hopper 3, powder to be added is added；Hopper 3 and still 1 is connected by charge pipe 4, and one end of charge pipe 4 is goed deep in still 1 below liquid level；In order to avoid the liquid phase of still enters charge pipe 4, described charge pipe 4 enters the subsurface one end of still 1 and has check valve 5.
4) ball valve 6 of hopper 3 and charge pipe 4 junction is opened, under the effect of pull of vacuum, need the powder added to keep vacuum in still 1 by vacuum pump 2 by charge pipe 4 automatically into still 1, charging simultaneously, the powder making needs add constantly is inhaled into still 1, until powder adds.
The most whole process is carried out under semi-closed state, and under the conditions of negative pressure of vacuum, powder is directly entered below liquid level, will not airborne dust, safe and efficient；Powder dispersion effect in the liquid phase is preferable simultaneously.
In the present embodiment, charge pipe 4 is to be directly entered under still 1 liquid level, it is also possible to being positioned at bottom the still 1 of below liquid level or side is provided with charging aperture, charge pipe 4 is connected with these charging apertures, and powder is after charge pipe 4 under the liquid level in these charging apertures enter still 1.
Being further used as preferred embodiment, above-mentioned charge pipe 4 can have a plurality of, so that material dispersion is evenly.
Above the better embodiment of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement on the premise of spirit of the present invention, and modification or the replacement of these equivalents are all contained in the application claim limited range.
