Problems solved by technology

The scheme of installing a sewage pump in the water collection well to lift the sewage has the following defects: the power supply voltage of the sewage pump is not a safe voltage (220V or 380V), which may easily cause potential safety hazards; the sewage pump is easy to block, and it is inconvenient to clean and maintain; Balanced, it has a big impact on the pipeline system, and it is easy to cause water accumulation in the well to overflow when there is a power failure

Abstract

The invention relates to a sump well for a vacuum drainage system. The sump well comprises a collection well, a sewage pumping pipe, a drainage pipe, a vacuum valve, a controller for controlling connection and disconnection of the vacuum valve and a water level sensor for collecting water level information, wherein the outlet of the drainage pipe is connected into a vacuum pipeline, and the inlet of the drainage pipe is connected with the outlet of the sewage pumping pipe through the vacuum valve; the inlet of the sewage pumping pipe extends into a sewage pumping level in the collection well; and a signal output end of the water level sensor is connected with a signal input end of the controller. Along with sewage collection in the well, the sump well drains automatically and intermittently to the vacuum drainage system, has a simple structure, and does not require a lift pump, so that the problems of being low in safety, easy in blockage, difficult in cleaning, high in power consumption and the like caused by assembling the lift pumps on multiple points can be avoided, and sewage collected by gravity flow can be lifted to the vacuum drainage system without extra additional power, and the sump well is convenient to check and maintain.

Description

technical field [0001] The invention relates to a water accumulation well, in particular to a water accumulation well used in a vacuum drainage system, which is used for collecting and transporting sewage brought in by gravity flow. Background technique [0002] The existing main way of discharging building domestic sewage to the outside is to first collect the indoor sewage into the sump well by gravity, and then discharge the sewage into the gravity flow sewage pipe from the sump well. This drainage method is widely used in building drainage. Its defect is that when the elevation of the indoor sewage main pipe is lower than the outdoor main drainage pipe, sewage pumps can only be installed in the sump to lift the sewage into the outdoor main drainage pipe. The scheme of installing a sewage pump in the water collection well to lift the sewage has the following defects: the power supply voltage of the sewage pump is not a safe voltage (220V or 380V), which may easily cause p...
