Description
Technical field:
The utility model relates to the technical field of sewage collecting, specifically a kind of negative pressure gathering-device that is used for outdoor sewage.
Background technology:
In the city and the intensive area of resident population, gravity pipeline collection mode is adopted in the collection of sewage more, effluent stream in the building is gone into outdoor inspection shaft, and sewage conduct lays by certain gradient, and sewage relies on gravity along line transportation to the sewage winding shaft, rise to sewage treatment facility by pumping plant then, for preventing that sewage stops up in the pipeline, often need to adopt certain gradient during pipeline laying, therefore, the general buried depth of sewage conduct is darker relatively, the construction investment height.And in the rural area, disperse relatively owing to live, particularly change greatly in the rural area landform, under the river situation how, as rely on traditional gravity pipe line collection mode, and pipeline need be kept certain gradient, and it is bigger to lay difficulty, pipeline is implemented difficulty, what have can't implement at all, causes much counting the random discharging modes that the sewage in villages can only be taked, and particularly the country sewage amount is little, sewage running piping is long, therefore, sewage flow velocity when drought flows is little in the pipeline, pipeline easily stop up and seepage serious, dry days, sewage directly permeated the ground mostly, collection is less than sewage, and when the rainy day because rainwater infiltrates, sewage overflow is serious, the river, rural area is generally polluted, also serious threat is to underground water, sternly must influence surrounding environment, brings bigger threat for resident's health.Therefore, change under the big situation at sparsely populated, landform, how country sewage is effectively collected is to be badly in need of the difficult problem that solves at present.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved negative pressure gathering-device that is used for outdoor sewage, it is big that it can overcome in the prior art traditional gravity drainage system buried depth of pipeline, the operation maintenance difficulty, particularly to rural residence disperse, landform changes the some shortcomings that situation greatly is difficult to adapt to.
To achieve these goals, the technical solution of the utility model is: a kind of negative pressure gathering-device that is used for outdoor sewage, it mainly comprises the negative pressure collecting tank, it is characterized in that: the negative pressure collecting tank is connected with at least one collector unit, link to each other by the negative pressure pipe between negative pressure collecting tank and the collector unit, collector unit is by water inlet pipe, sewage collecting well and water sealing (sealing water) pipe are formed by connecting, link to each other by collecting the well outlet pipe between sewage collecting well and the water sealing (sealing water) pipe, be provided with a suction tube in the water sealing (sealing water) pipe, the negative pressure collecting tank is provided with high vacuum switch and low vacuum switch, negative pressure collecting tank top is connected with vacuum pump, and negative pressure collecting tank bottom is connected with drainage pump.
The beneficial effects of the utility model are to adopt negative-pressure pipeline that the sewage in each sewage collecting well is collected, the negative-pressure pipeline buried depth does not need to lay by certain gradient, can effectively reduce the sewage conduct laying depth, the collection conduit caliber is less, engineering construction is easy, construction investment is low, simultaneously owing to adopt negative-pressure sealed pipeline to collect, the seal for pipe joints performance is good, can effectively avoid effluent seepage and rainwater to infiltrate phenomenon, flow velocity is relatively large in the sewage conduct, helps reducing sewage deposition and clogging, helps the operation and the management of sewage collecting pipe network.

Fig. 2 is the structural representation of the utility model collector unit
Fig. 3 is the structural representation of the another embodiment of the utility model
The specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises negative pressure collecting tank 6, its difference with the prior art is: the negative pressure collecting tank is connected with at least one collector unit, link to each other by negative pressure pipe 5 between negative pressure collecting tank and the collector unit, collector unit is formed by connecting by water inlet pipe 1, sewage collecting well 2 and water sealing (sealing water) pipe 3, link to each other by collecting well outlet pipe 9 between sewage collecting well and the water sealing (sealing water) pipe, be provided with a suction tube 4 in the water sealing (sealing water) pipe.The negative pressure collecting tank is connected with 1-100 collector unit, the top of water sealing (sealing water) pipe is provided with a blank flange 10, and suction tube passes through blank flange and is arranged in the water sealing (sealing water) pipe, an end distance of suction tube is dried up tube sealing bottom 0.1m, the other end of suction tube links to each other with the negative pressure pipe, and the length B of water sealing (sealing water) pipe is 2-4m.The negative pressure collecting tank is provided with high vacuum switch 11 and low vacuum switch 12, and negative pressure collecting tank top is connected with vacuum pump 8, and negative pressure collecting tank bottom is connected with drainage pump 7.Suction control valve 13 is set between suction tube and the negative pressure pipe, and the sewage collecting well is embedded in below ground, and the sewage collecting bottom is connected with the water sealing (sealing water) pipe top by collecting the well outlet pipe.
In force, the negative pressure collecting tank links to each other with 1 ~ 100 collector unit by the negative pressure pipe, at collector unit, between negative pressure pipe and the sewage collecting well water sealing (sealing water) pipe and suction tube are set, the sewage collecting well adopts brick or plastic or other material to be embedded in below ground, be used for receiving and of short duration storage family discharge sanitary sewage, the sewage collecting bottom is communicated with the trapped well top by outlet pipe, water sealing (sealing water) pipe adopts steel pipe or UPVC pipe, imbeds underground by boring, and diameter is DN100 ~ DN200, about 2 ~ 4 meters of length, negative pressure suction arm stretches in the trapped well by top blank flange one end, 0.1 meter of dried up shut-in well bottom, and the other end is connected with the negative pressure pipe.When normal operation, sewage gravity flows to outdoor sewage collecting well in the family, do short stay at the sewage collecting well, under the situation that vacuum pump is opened in vacuum station, sewage gravity enters trapped well, be flowed to the negative pressure pipe by the suction arm again, flow in the sewage collecting jar by the negative pressure pipe again, according to the regular opening water discharge pump of the sewage level in sewage collecting jar effluent sewerage, in trapped well, form water seal, the minimum negative pressure of control sewage collecting jar and high negative pressure during operation, when minimum negative pressure, liquid level is lower than the sewage collecting bottom in the trapped well, and the sewage in the sewage collecting well can be found time, when high negative pressure, the liquid level in the trapped well is higher than suction arm bottom to guarantee that water seal does not destroy.
