Detailed description of the invention
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
The vertical section schematic diagram of the prefabricated pumping plant with water knockout drum that Fig. 1 provides for this utility model embodiment；The schematic top plan view of the prefabricated pumping plant with water knockout drum that Fig. 2 provides for this utility model embodiment.Shown in Fig. 1, Fig. 2, in the present embodiment, the prefabricated pumping plant with water knockout drum includes: cylinder 9, bottom 2, submersible sewage pump 3, water knockout drum 1, water inlet pipe 7 and hand basket grid 6；
Cylinder 9 is cylindric, airtight with bottom 2 connects, and forms the bottom of prefabricated pumping plant；
Water inlet pipe 7 is arranged at the top of prefabricated pumping plant, introduces sewage in prefabricated pumping plant；
Concrete, the end of water inlet pipe 7 has inlet pipe elbow 8, and inlet pipe elbow 7 connects with hand basket grid 6.
Hand basket grid 6 carries out separating and filtering by exceeding the solid particle being sized in sewage, and the sewage after filtration is fallen in the bottom of prefabricated pumping plant by hand basket grid 6；Meanwhile, along with sewage freely falling body, the sewage of the bottom accumulation that will also result in prefabricated pumping plant produces substantial amounts of bubble.
Submersible sewage pump 3, is arranged on bottom 2；
Concrete, submersible sewage pump 3 can be one, it is also possible to is multiple.In the example shown in Fig. 2, submersible sewage pump 3 is two, and they are symmetrical arranged along the line of centres of hand basket grid 7 with water knockout drum 1.
Water knockout drum 1, is arranged on bottom 2, and between the hand basket grid 6 upright projection position and submersible sewage pump 3 on bottom 2；Water knockout drum 1 is made in gusset shape, preferably glass steel material.Including two deflectors 11 connected at an angle.This angle is preferably 90 degree, and joint is rounded.After sewage after filtration arrives the bottom of prefabricated pumping plant, current are walked around water knockout drum 1 and are arrived the pumping hole of submersible sewage pump, and the bubble in sewage floats to discharge on liquid level along the wooden partition of deflector 11.
Preferably, the bottom of water knockout drum 1 offers one or more current through-hole 12, the most as shown in Figure 3.In a specific example, the size of the saturating through hole of current 12 is 300 (mm) x150 (mm).
Thereby guarantee that above the bottom 2 of the prefabricated pumping plant of buried wet type, drainage flow is unimpeded, it is to avoid on the bottom 2 of the prefabricated pumping plant of buried wet type, produce dirt deposition.
Further, then as it is shown in figure 1, the two ends of two deflectors 11 of water knockout drum 1 are respectively beyond the center 80mm-100mm of submersible sewage pump 3, and and submersible sewage pump 3 between have certain spacing, the apical position of water knockout drum 1 is higher than termination of pumping liquid level 100mm-150mm.Ensure that water velocity can effectively be reduced by said structure, will not flow directly at submersible sewage pump 3, the most also ensure that submersible sewage pump 3 will not be by peripheral interference when being raised maintenance.
Concrete in the example shown in Fig. 2, the two ends of two deflectors 11 of water knockout drum 1 are respectively beyond the center 80mm-100mm of a submersible sewage pump of respective side.
Additionally, in order to accurately control pumping plant work, the cylinder 9 of prefabricated pumping plant is provided with liquid level sensor (not shown), it is used for detecting the sewage deep of the bottom accumulation of prefabricated pumping plant.
When sewage deep meets or exceeds startup liquid level (identifying at 5 in Fig. 1), liquid level sensor produces enabling signal makes submersible sewage pump 3 start work；When sewage deep is less than termination of pumping liquid level (identifying at 4 in Fig. 1), liquid level sensor produces stopping signal making submersible sewage pump 3 quit work.
The specific works process of the prefabricated pumping plant with water knockout drum that the present embodiment provides is as follows:
Sewage, rainwater and rain dirt river wastewater flow through inlet pipe elbow 8 by the water inlet pipe 7 on prefabricated pumping plant and sewage, rainwater and rain dirt river wastewater are emitted in basket grid 6, are separated by the big solid particle in sewage by basket grid 6；Fine particle and sewage fall on the bottom 2 of the prefabricated pumping plant of buried wet type through basket grid 6, and sewage water knockout drum 1 along buried wet type prefabricated pumping plant bottom 2 flows, and is shunted by the bubble contained, thus reach sewage and bubble separation in sewage.When in the prefabricated pumping plant of buried wet type, liquid level reaches to start liquid level, submersible sewage pump 3 starts, and by sewage lifting to corresponding treatment tank, until liquid level is less than termination of pumping liquid level, submersible sewage pump 3 quits work.
The prefabricated pumping plant with water knockout drum that this utility model embodiment provides, the water knockout drum on pumping plant bottom plate is utilized to increase the sewage injection phase circulation length to submersible sewage pump pumping hole, so that bubble produced by freely falling body bottom entrance pumping plant has enough time to rise discharge during the sluggish flow of liquid in sewage, gas-liquid is efficiently separated, bubble is sucked when avoiding submersible sewage pump to run, produce the generation of the phenomenon such as cavitation, vibrations, improve the operating condition of submersible sewage pump, increase the service life of submersible sewage pump.
Above-described detailed description of the invention; the purpose of this utility model, technical scheme and beneficial effect are further described; it is it should be understood that; the foregoing is only detailed description of the invention of the present utility model; it is not used to limit protection domain of the present utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. done, within should be included in protection domain of the present utility model.
