Background
The water-gas separating and draining equipment for soft foundation vacuum preloading treatment engineering consists of vacuum pump set, water-gas separating tank and water draining device. The common drainage device in the market is to place a drainage pump in a water-gas separation tank or attach an ejector type negative pressure drainage. Arrange the drain pump in the drainage device of water gas knockout drum, equipment need carry out the dismouting to jar body and relevant pipeline annex when installation or troubleshooting, and constructor bores jar internal installation and changes the drain pump, and the process needs the assistance of multiple constructors, and wades during the operation, has the potential safety hazard. The drainage device adopting ejector type negative pressure needs more matched equipment, is troublesome to install and transport, leads to the increase of construction cost, and has low drainage efficiency in actual work and can not meet the drainage requirement at the initial construction stage. Therefore, the water-gas separation drainage device in the traditional soft foundation vacuum preloading treatment project cannot meet the economical construction requirement of the modern soft foundation treatment project.
Disclosure of Invention
In order to overcome the not enough of prior art, the utility model provides an external aqueous vapor separation drainage device of drain pump, it just need not to dispose the project organization of ejector through the drain pump external water vapor knockout drum, realizes that corollary equipment is few, use cost is low, the maintenance is convenient, the purpose that the displacement is big.
The utility model discloses a following technical scheme implements: an external water-gas separation drainage device of a drainage pump comprises a drainage plate water collection system, a water-gas separation tank, a vacuum pump set, the drainage pump and a valve, wherein a tank body of the water-gas separation tank is provided with a water inlet, a water outlet and an exhaust port, and the water outlet is arranged at the lower part of the side wall of the water-gas separation tank; a water collecting pipeline of the water collecting system of the drainage plate is communicated with a water inlet arranged on the water-gas separation tank body; the vacuum pump set is communicated with an air outlet arranged on the water-gas separation tank body through an air exhaust pipeline, and a negative pressure cavity is formed in the water-gas separation tank when the vacuum pump set operates; the valve is arranged on a pipeline at the water outlet of the drainage pump, and is characterized in that:
the drainage pump is arranged outside the water-gas separation tank, and a water inlet of the drainage pump is connected with the water outlet of the water-gas separation tank;
and a communicating pipeline leading to the negative pressure cavity in the water-gas separation tank is arranged on a water outlet pipeline between the drainage pump and the valve.
Further, the drain outlet of the drain pump is directed to the pump body of the drain pump, and the drained water cools the drain pump.
The utility model discloses arrange the water vapor knockout drum body's outside in with the drain pump to set up the pipeline that leads to water vapor knockout drum negative pressure chamber on its outlet conduit, can effectively get rid of the pump and overflow the bubble that the partial region of part produced and avoid the cavitation, thereby make the drain pump arrange the water vapor knockout drum outside and need not corollary equipment's technical scheme and can implement, realized that water vapor separator use cost is low, overhaul and maintain convenient and the purpose that the displacement is big.
