Description

Basement drainage system

Technical Field

The invention belongs to the technical field of sewage treatment, and relates to a basement drainage system.

Background

Many houses all design the basement, because basement relief is lower, often can not give and directly discharge sewage to the water collecting and treating pond, like methane-generating pit etc. need equipment such as water pump to go up to take out, and general way does: the equipment room is arranged below the basement, the built-in sewage discharge equipment is arranged in the equipment room, the built-in sewage discharge equipment generally comprises a small sewage pool and a sewage storage pool which pumps sewage in the sewage pool to be close to the ground, so that sewage generated by at least a building layer on the ground and sewage generated by the basement are stored in the sewage storage pool and are subjected to centralized treatment and discharge. Set up the equipment room in basement below and not only improved building construction cost, it is very inconvenient to maintain moreover, and equipment such as water pumps that are located small-size sewage pond also have the fault rate higher (like jam, accessory corruption ageing etc.), be unfavorable for the maintenance and follow the trade.

In order to reduce sewage treatment capacity, the urban newly-developed area generally adopts rainwater and sewage split-flow dual-control system, and this part of rainwater is relatively clean water that can be directly discharged, generally directly discharges to the river, does not carry out better utilization to rainwater among the prior art.

The sewage collecting tank can be a methane tank or a reservoir without sewage treatment function.

The working principle of the basement drainage system is as follows: domestic sewage that produces in the basement passes through basement sewage pipes and emits into basement sewage and keeps in the pond, the domestic sewage that the each floor of overground part of building produced emits into the sewage catch basin through overground layer sewage pipes, the rainwater that the building roof was collected and the rainwater that ground converges get into the rainwater catch basin, solid-liquid separation mechanism carries out solid-liquid separation with the sewage in basement sewage keeps in the pond, the solid sends into the sewage catch basin through outer spiral guide piece, liquid is through first water pump pumping to sewage catch basin, solid-liquid separation mechanism has better effect, specifically: the solid-liquid mixture is promoted under the condition that the inner sleeve rotates in the forward direction, part of liquid can be filtered into the inner sleeve through the filter holes, the liquid which is pumped by the water pumping pipe in the inner sleeve can be ensured not to suck the solid material which causes the blockage of the first water pump, meanwhile, the negative pressure is generated in the inner sleeve by the water pumping pipe, so that the liquid in the mixed material between the inner sleeve and the outer sleeve can better enter the inner sleeve, the solid-liquid separation efficiency and effect are improved, because the lower end of the inner sleeve extends to the lower part of the outer sleeve, the negative pressure in the inner sleeve can enable the solid-liquid mixture at the lower end of the outer sleeve to be close to the inlet of the outer sleeve, so that the basement sewage pool is not easy to generate solid deposition, manual cleaning is needed if the solid deposition is generated temporarily, or the blockage of the outer sleeve can be caused.

The solid-liquid separation mechanism has a reverse cleaning function, works when the liquid level in the basement sewage temporary storage tank reaches a set height, carries out solid-liquid separation on a sewage mixture and then sends the sewage mixture into the sewage collecting tank, and carries out reverse cleaning once after the solid-liquid separation mechanism pumps water in the forward direction at each time so as to avoid blockage of the filtering hole, the inner sleeve and the outer sleeve and also avoid accumulation and precipitation of solid materials near the lower end of the outer sleeve. The working principle of the reverse cleaning is as follows: interior sleeve pipe antiport, the solid material that probably stores up in the outer tube is ordered about to outer spiral guide piece and is returned to basement sewage and keep in the pond, and the intraductal water that lets in certain pressure that produces of interior sleeve, and the water source is comparatively clean water in the rainwater catchment pond, and the water that has certain pressure is reverse to washing worry the hole, including in the sleeve pipe lower extreme gets into the outer tube, also washs the outer tube, also can cross simultaneously and keep in the pond basement sewage and be close to the region of outer tube lower extreme and clear stifled.

When reverse cleaning is carried out, water in the inner sleeve is pressurized and stirred through the pressurizing guide vane.

This system utilizes the comparatively clean water of rainwater catch basin to carry out reverse washing to solid-liquid separation mechanism, and is with low costs, effectual, moreover, and first water pump, gear motor and second water pump all are close to ground in this system, and easy access and with trading need not to set up the equipment room below the basement, only need less volumetric basement sewage pond of keeping in, have reduced construction cost.

A floating ball control switch is arranged in the basement sewage temporary storage tank, so that the first water pump and the speed reduction motor are started actively.
