Abstract
The utility model provides a vacuum suction device of an acid pump. The vacuum suction device of the acid pump comprises a liquid storage tank, a sealed container, a liquid sucking tube and a liquid discharging tube, wherein the sealed container is located above the liquid storage tank, and the liquid discharging tube is arranged at the bottom of the sealed container. The upper portion of the liquid sucking tube is located in an inner cavity of the sealed container. The bottom of the liquid sucking tube is located in the liquid storage tank. A tube opening of the liquid sucking tube is lower than the upper plane of the inner cavity. The liquid discharging tube is connected to a centrifugal pump. The sealed container is filled with liquid. When the liquid level in the inner cavity is flush with the upper tube opening of the liquid sucking tube, the centrifugal pump is started. Under the centrifugal force of the centrifugal pump, a vacuum area is formed in the inner cavity, acid liquid in the liquid storage stank is continuously pressed into the inner cavity of the sealed container through the liquid sucking tube under the action of negative pressure. When the centrifugal pump is stopped, the liquid in the liquid discharging tube of the centrifugal pump flows back into the inner cavity under the action of gravity and negative pressure, and therefore the liquid level in the inner cavity is always flush with the upper tube opening of the liquid sucking tube. As a result, when started next time, the pneumatic centrifugal pump can smoothly suck acid liquid.
Description
Technical field
The utility model relates to sour pump technical field, is specifically related to a kind of sour pump aspirator.
Background technique
The suction means of phosphoric acid liquid is by a relevant centrifugal pump of the access of the pipeline with one-way bottom valve at present, when centrifugal pump rotates, between liquid entering hole and centrifugal impeller, form higher than barometric pressure and to the pressure of liquid outlet direction, liquid is under the effect of this suction, through liquid entering hole, flow into, by liquid outlet, flowed out.But due to the cleanliness of liquid and the sealing of one-way bottom valve impact, there will be certain aneroid space at one-way bottom valve and pump class liquid entering hole, now liquid just can not be sucked out, so associated pump class hermetic unit is because long-time aneroid operation very easily damages.
Summary of the invention
The utility model, in order to overcome the deficiency of above technology, provides a kind of sour pump vacuum suction that liquid damages pump seal that prevents from not inhaling.
The utility model overcomes the technological scheme that its technical problem adopts:
This sour pump vacuum suction, comprise liquid storage tank, be positioned at seal container, the pick-up tube of liquid storage tank top and the drain pipe that is arranged at seal container bottom, described pick-up tube top is arranged in the inner chamber of seal container, its bottom is arranged in liquid storage tank, the mouth of pipe height of described pick-up tube is lower than the upper plane of inner chamber, and described drain pipe is connected in centrifugal pump.
In order to facilitate the initial stage to add diversion, also comprise the valve that is installed on seal container top.
The beneficial effects of the utility model are: will in this seal container, fill liquid, until the liquid level in inner chamber is concordant with the upper orifice of pick-up tube, start centrifugal pump, this centrifugal pump is under the effect of centrifugal force, make to form a region of no pressure in this inner chamber, the acid solution in liquid storage tank will be pressed in the inner chamber of seal container through pick-up tube constantly by the effect of negative pressure.When centrifugal pump stops, liquid in centrifugal pump drain pipe pipeline flows back to again in inner chamber under the effect of gravity and negative pressure, thereby make the liquid level in inner chamber remain at the position concordant with the pick-up tube upper end mouth of pipe, during therefore lower task, Pneumatic centrifugal pump can be drawn acid solution smoothly, do not need to rejoin diversion and get final product work, effectively prevent from not inhaling the situation generation that liquid damages pump seal.
Accompanying drawing explanation
Fig. 1 is structure principle chart of the present utility model;
In figure, 1. centrifugal pump 2. valve 3. seal container 4. inner chamber 5. pick-up tube 6. liquid storage tank 7. drain pipes.
Embodiment
Below in conjunction with 1 pair of the utility model of accompanying drawing, be described further.
This sour pump vacuum suction, comprise liquid storage tank 6, be positioned at seal container 3, the pick-up tube 5 of liquid storage tank 6 tops and the drain pipe 7 that is arranged at seal container 3 bottoms, pick-up tube 5 tops are arranged in the inner chamber 4 of seal container 3, its bottom is arranged in liquid storage tank 6, the mouth of pipe height of pick-up tube 5 is lower than the upper plane of inner chamber 4, and drain pipe 7 is connected in centrifugal pump 1.To in this seal container 3, fill liquid, until the liquid level in inner chamber 4 is concordant with the upper orifice of pick-up tube 5, start centrifugal pump 1, this centrifugal pump 1 is under the effect of centrifugal force, make to form a region of no pressure in this inner chamber 4, the acid solution in liquid storage tank 6 will be pressed in the inner chamber 4 of seal container 3 through pick-up tube constantly by the effect of negative pressure.When centrifugal pump 1 stops, liquid in centrifugal pump 1 drain pipe 7 pipelines flows back to again in inner chamber 4 under the effect of gravity and negative pressure, thereby make the liquid level in inner chamber 4 remain at the position concordant with the pick-up tube 5 upper end mouths of pipe, during therefore lower task, Pneumatic centrifugal pump 1 can be drawn acid solution smoothly, do not need to rejoin diversion and get final product work, effectively prevent from not inhaling the situation generation that liquid damages pump seal.
Also comprise the valve 2 that is installed on seal container 3 tops, when using for the first time, valve 2 is opened, then can in pick-up tube 5, inject diversion, until fill, then throttle down 2, can make the inner negative pressure that forms of inner chamber 4 in seal container 3 in centrifugal pump 1 working room, thereby extract the acid solution in liquid storage tank 6, thereby convenient assembling is for the first time used.
