Description
Technical field
The utility model relates to a kind of liquid pumping equipment, more specifically says a kind of liquid pumping equipment of solid material sedimentation containing solid particle erosion liquid that is applied to.
Background technique
Current liquid pump structure is mainly divided into power section and power-conversion part.Power section is motor or other device.Power-conversion part is all designed to a cavity, in cavity, drive flow of fluid by impeller or barrier film, its shortcoming is that in cavity, fluid path is narrow, in the solid-state solid material of pumping sedimentation containing the corrosive liquids of solid particle time, easily occur that particle aggregation stops up, and the life-span of pump is because of corrosion reduction greatly; In addition, because of liquid sedimentation velocity variations, the load of pump also changes thereupon, often occurs that sinking velocity is slower than pumping rate, causes pump idle running, has shortened the life-span of pump; Must manually see tube apparatus operation, be responsible for start and shut down, prevent that sky machine from turning round and liquid container overfill is overflowed, reduce working efficiency.
Model utility content
The utility model is for avoiding the existing deficiency of above-mentioned prior art, a kind of anti-plugging liquid pump apparatus is provided, in the corrosive liquids situation that this equipment contains solid particle polluter as pumping, use, especially the in the situation that of liquid continuous sedimentation, use, to reaching the life-span of anti-plugging, corrosion protection, prolongation pump, the object of increasing work efficiency.
The utility model is that technical solution problem adopts following technological scheme:
The utility model anti-plugging liquor pump, its structural feature is: liquid container is set, for controlling the vacuum pump of described liquid container internal air pressure and disconnecting the buoyancy limit switch of described vacuum pump working circuit when liquid level reaches limit value in described liquid container,
On described liquid container, be provided with water intake and dewatering outlet; Outside at described liquid container is provided with the level meter for measuring liquid level in described liquid container along short transverse.
Anti-plugging liquor pump of the present utility model, its structural feature is also: in described liquid container, be provided with gather described liquid container internal air pressure signal baroceptor and according to the pressure signal control unit of vacuum pump work described in described air pressure signal control.
Be provided with transparent observing mouth at described liquid container upper surface.
In described water inlet, filter screen is installed.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the utility model uses in vacuum pump control liquid container and forms negative pressure, drives liquid to flow in liquid container, does not directly contact the pump housing, has avoided obstruction and the corrosion to the corrosive liquids pump housing, has extended working life;
2, the utility model, by the Operational Limits of pressure signal control unit control vacuum pump, makes the conveying of liquid in optimum condition, and without manual operation, has reduced labor intensity, has improved working efficiency;
3, the utility model uses buoyancy limit switch when liquid level reaches limit value in liquid container, to disconnect vacuum pump working circuit, can effectively prevent overflow;
Whether 4, the utility model is provided with transparent observing mouth on liquid container, can observe real-time and easily the situation in liquid container, for example, intake in real time;
5, the utility model is provided with level meter in the outside of liquid container along short transverse, can Real Time Observation to the level condition in liquid container.

Number in the figure: 1 transparent observing mouth; 2 vacuum pumps; 3 buoyancy limit switches; 4 liquid containers; 5 dewatering outlets; 6 pressure signal control units; 7 baroceptors; 8 level meters; 9 water intakes.
Embodiment
As shown in Figure 1, the present embodiment anti-plugging liquid pump structure is: liquid container 4 is set, for controlling the vacuum pump 2 of liquid container 4 internal air pressures and for disconnect the buoyancy limit switch 3 of described vacuum pump working circuit in the time that the interior liquid level of liquid container 4 reaches limit value; On liquid container 4, be provided with water intake 9, be provided with dewatering outlet 5 in the bottom of liquid container 4;
Outside at liquid container 4 is provided with the level meter 8 for measuring liquid container 4 interior liquid levels along short transverse, can Real Time Observation to the level condition in liquid container.
In liquid container 4, be provided with and gather the baroceptor 7 of liquid container 4 internal air pressure signals and the pressure signal control unit 6 of working according to air pressure signal control vacuum pump 2.
Be provided with transparent observing mouth 1 at liquid container upper surface, can observe real-time and easily the situation in liquid container, for example, whether intake in real time.
At water intake, 9 places are provided with filter screen, can effectively filter and enter the contained solid particle of liquid in liquid container.
When use; the gas that vacuum pump 2 extracts in liquid container 4 forms negative pressure; drive liquid to enter liquid container 4 from water intake 9; liquid level rises; can observe level condition by level meter 8; also can check whether in real time water inlet of water intake 9 by transparent observing mouth 1; baroceptor 7 is responded to liquid container internal air pressure signal; signal is controlled amendment vacuum pump 2 Operational Limitss by pressure signal control unit 6; make in optimum condition; after liquid container 4 is full, buoyancy limit switch 3 is subject to floating function disconnecting circuit to cut out vacuum pump 2, after shutdown, can emit liquid from dewatering outlet 5.
