Abstract
The utility model relates to a drainage system for bathrooms of underground buildings; the drainage system comprises a pump station which is respectively connected with a closet pan, a urinal and a wash basin, wherein the pump station is of a vacuum pump station, one end of the vacuum pump station set is connected with a blowdown pipeline 2, and the other end of the vacuum pump station set is connected with a municipal sewage pipe network; the blowdown pipeline is connected with the closet pan through a drain valve and is connected with the urinal through another drain valve; the blowdown pipeline is connected with the wash basin through a water storage tank; and the other one drain valve is arranged in the water storage tank. The drainage system adopts a vacuum suction manner and saves about more than one half of flushing water under the condition that the same flushing effect is achieved.
Description
Technical field
The utility model relates to a kind of underground structure toilet drainage system.
Background technology
The underground structure toilet drainage mostly uses the gravity drainage technology at present; Be that sewage, the waste water that produces in the washroom flows in the temporary sewage reservoir in the pump house through the gravity blowoff line earlier; When the sewage in the sewage reservoir, waste water reach a constant volume; The dredge pump that is located in the pump house is started working, and the dirt in the sewage reservoir, waste water are promoted and is drained in the municipal blowdown pipe network on ground.Because adopt gravity drainage, the shortcoming of this drainage system is when the laying of blowoff line, must have certain gradient and potential difference, sewage reservoir must be located in the space of washroom subterranean layer, and can't realize does not have draining under the situation of potential difference with layer; The sewage reservoir floor space is big in addition, and sealing difficulty is big during construction, causes the interior stink of pump house big; And gravity drainage only depends on water to wash lavatory pan, and to wash water consumption big at every turn, the waste precious water resource.
Summary of the invention
The utility model is to the deficiency of above-mentioned prior art, and a kind of underground structure toilet drainage system is provided.Has advantage simple in structure, easy to use.
The concrete technical scheme of the utility model is:
A kind of underground structure toilet drainage system comprises pumping plant 1, and this pumping plant 1 links to each other with lavatory pan 3, urinal 4, washing basin 5 respectively through blow-off line 2;
Said pumping plant is a Vacuum Pumps Station, and an end of Vacuum Pumps Station unit is connected with blow-off line 2, and the other end of Vacuum Pumps Station unit links to each other with the municipal wastewater pipe network;
Said blow-off line 2 is connected with lavatory pan 3 through bleed valve 7;
Said blow-off line 2 is connected with urinal 4 through bleed valve 7;
Said blow-off line 2 links to each other with washing basin 5 through reservoir 8, and reservoir 8 is provided with bleed valve 7.
Further, this pumping plant 1 links to each other with mop service sink 6 through reservoir 8 through blow-off line 2, and reservoir 8 is provided with bleed valve 7.
The utility model is provided with Vacuum Pumps Station in pumping plant, pumping plant is connected to the washroom through blow-off line, and the export pipeline of pumping plant links to each other with the municipal wastewater pipe network; During Vacuum Pumps Station work, produce vacuum in the blow-off line, can be inhale the sewage of coming, waste water pressurization back enters ground through the pumping plant export pipeline municipal wastewater pipe network from blow-off line.Bleed valve through blow-off line and installation in the washroom connects lavatory pan, urinal; When toilet stool washing, bleed valve is opened, closet and blow-off line vacuum communicating; Flushing water begins to wash bedpan simultaneously; Sewage in the bedpan is transported to Vacuum Pumps Station through blow-off line under the acting in conjunction of the suction force of vacuum and water flushing ability, under the duty of Vacuum Pumps Station, be discharged in the municipal wastewater pipe network on ground.
Sewage, waste water that washing basin, mop service sink produce can utilize action of gravity to collect in the reservoir earlier, and reservoir is provided with bleed valve; When the liquid level in the reservoir reaches the setting liquid level; Bleed valve is opened automatically, is connected through the vacuum in the blow-off line, and sewage, waste water in the reservoir are transported to Vacuum Pumps Station through blow-off line under the suction force effect of vacuum; Under the duty of Vacuum Pumps Station, be discharged in the municipal wastewater pipe network on ground.
The beneficial effect of the utility model:
The utility model need not to be provided with sewage reservoir, has practiced thrift the area of pump house, adopts Vacuum Pumps Station and closed system, and air ambient is good in washroom and the pump house, has improved the working environment in the pump house.In addition, in the flushing process of lavatory pan, adopt the mode of vacuum draw, reaching under the situation of equal developing result, practiced thrift about 1/2 above wash water.The utility model blow-off line is to adopt the vacuum transmission, can realize co-layer draining.

Fig. 1 is the underground structure toilet drainage system architecture sketch map of the utility model.
Among the figure: 1, pumping plant, 2, blow-off line, 3, lavatory pan, 4, urinal, 5, washing basin, 6, the mop service sink, 7, bleed valve, 8, reservoir.
The specific embodiment
As shown in Figure 1, a kind of underground structure toilet drainage system comprises pumping plant 1, and this pumping plant 1 links to each other with lavatory pan 3, urinal 4, washing basin 5 respectively through blow-off line 2; Said pumping plant is a Vacuum Pumps Station, and an end of Vacuum Pumps Station unit is connected with blow-off line 2, and the other end of Vacuum Pumps Station unit links to each other with the municipal wastewater pipe network; Said blow-off line 2 is connected with lavatory pan 3 through bleed valve 7; Said blow-off line 2 is connected with urinal 4 through bleed valve 7; Said blow-off line 2 links to each other with washing basin 5 through reservoir 8, and reservoir 8 is provided with bleed valve 7; This pumping plant 1 links to each other with mop service sink 6 through reservoir 8 through blow-off line 2, and reservoir 8 is provided with bleed valve 7.
When the vacuum pumping plant is worked, produce vacuum in the blow-off line, can be inhale the sewage of coming, waste water pressurization back enters ground through the pumping plant export pipeline municipal wastewater pipe network from blow-off line.Bleed valve through blow-off line and installation in the washroom connects lavatory pan, urinal; When toilet stool washing, bleed valve is opened, closet and blow-off line vacuum communicating; Flushing water begins to wash bedpan simultaneously; Sewage in the bedpan is transported to Vacuum Pumps Station through blow-off line under the acting in conjunction of the suction force of vacuum and water flushing ability, under the duty of Vacuum Pumps Station, be discharged in the municipal wastewater pipe network on ground.
Sewage, waste water that washing basin, mop service sink produce can utilize action of gravity to collect in the reservoir earlier, and reservoir is provided with bleed valve; When the liquid level in the reservoir reaches the setting liquid level; Bleed valve is opened automatically, is connected through the vacuum in the blow-off line, and sewage, waste water in the reservoir are transported to Vacuum Pumps Station through blow-off line under the suction force effect of vacuum; Under the duty of Vacuum Pumps Station, be discharged in the municipal wastewater pipe network on ground.
The utility model need not to be provided with sewage reservoir, has practiced thrift the area of pump house, adopts Vacuum Pumps Station and closed system, and air ambient is good in washroom and the pump house, has improved the working environment in the pump house.In addition, in the flushing process of lavatory pan, adopt the mode of vacuum draw, reaching under the situation of equal developing result, practiced thrift about 1/2 above wash water.The utility model blow-off line is to adopt the vacuum transmission, can realize co-layer draining.
