Description

Drainage device

The utility model relates to a kind of dewatering installation, especially a kind of dewatering installation that prevents the diffusion of sewer foul smell, sewage backflow and prevent to stop up.

At present, kitchen in the esidential building and washroom sewer pipe, normally two kinds of methods are laid.A kind of is to adopt the draining of two-way sewer pipe, and promptly one the tunnel is used for kitchen water draining, and another road is used for the ight soil draining of washroom; Another kind is one road sewer pipe draining, be that the shared a kind of sewer pipe draining latter in kitchen and washroom can save a large amount of tubing than the former, reduce construction volume, building costs has been fallen at the end greatly, and it is indoor neat and artistic, for avoiding the fecal sewage for toilet foul smell to be diffused into the kitchen, insert sewer pipe again after the general N of employing type return pipe is isolated, but also there is wretched insufficiency in this method, in case promptly sewer pipe stops up, addle overflows, foul smell scatters, and need dismantle not only difficulty but also not easy to clean during mediation, and odor pollution room air, especially in the winter of northern China, door and window is closed, and the room air circulation is relatively poor, air pollution is serious and lasting, has a strong impact on people's health and physical and mental health.Chinese patent CN89212096.7 number a kind of water trap that can prevent odor pollution is disclosed, it is the cover plate by lower header that is embedded in the pond inner bottom part and upper end thereof, cage in the lower header and interior gutter thereof are formed, though this technology has solved foul smell diffusion and line clogging problem, it can't utilize existing pond, need build the pond that has 1 hydroecium again by laying bricks or stones, bother very much, and also trouble of cleaning, simultaneously also unhygienic, installation is wasted time and energy.

The utility model improves at the problem that prior art exists, and provides a kind of simple in structure, can utilize existing pond to install, easy for installation, processing and manufacturing easily, cost is low, easy to utilize, can satisfactorily resolve the dewatering installation of foul smell diffusion and line clogging.

The utility model is achieved by following manner: a kind of dewatering installation, comprise filtration fraction, coupling part and water-sealing part be totally three parts, feature of the present utility model is: said filtration fraction is for being installed on cylinder filter on the basin bottom hole by sealing mat and nut, its top is provided with the filter of level, filter center and surface are respectively equipped with can be by the circular hole of pull bar and the filter bores of evenly arranging, this filter bores can be a circular port, it also can be the hole of ring-type, the certain hole that also can adopt other geometry, the strainer lower end can partly be connected with connector by screw thread; Said connector is uncovered connector for band oblique cone lower end, top partly, be the size on connector top and measure-alike (or approaching) of filtration fraction, and its underpart size increases, its (referring to connector) is provided with annular retaining platform with the end that is connected of filtration fraction, and the uncovered of lower end can be connected with water-sealing part by screw thread; Said water-sealing part has a water seal housing that is connected with connector by screw thread, periphery and center are respectively equipped with annular seal-water tank and the outfall that the cross section is a semicircle in it, and top is provided with the taper manhole cover of inserting water sealed tank center 1/3rd height, be provided with and its pull bar at taper manhole cover top by being threaded, the pull bar bottom is provided with circular baffle plate and the outfall thereof on the annular retaining platform that may be stuck in connector, after the circular hole at filter center is passed on pull bar top, the draw ring of the taper manhole cover that can upwards lift pull bar and front end thereof is set in its end, simultaneously between filter and pull bar step (reducing place, pull bar top), spring is set, like this no external force or need not the situation of portable draw ring under, the taper manhole cover of pull bar front end places in the water of water sealed tank all the time, can intercept stink and up return.Each component of present technique can adopt the plastics manufacturing, also can adopt metal material certainly, are good but adopt plastics.The use and the course of work of present technique are, when toppling over and with the waste water of crossing, at first by filter and on filter bores, filter out the difficult bulk foreign material of discharging of sewer pipe, because the foreign material that leach are at the upper part of strainer, be easy to cleaning, waste water after the filtration is to dirty and by its bottom outfall, then between connector and taper manhole cover by and enter in the annular seal-water tank, owing to the taper manhole cover is inserted below the interior water surface of water sealed tank, therefore can intercept on the stink and return, and flow through in the annular seal-water tank lower part through its outfall discharge through the waste water that filters, if tiny assorted being deposited in the annular seal-water tank arranged this moment, when making waste water or claiming that sewage can not be arranged down, can upwards lift draw ring, carry on the taper manhole cover, deposit is gone out in the water sealed tank by sewage in the pond, accomplished just not dismantle and to have dredged pipeline.And the pollution indoor environment, when the water main line take place to stop up sewage and flows backwards instantly, the pressure of sewage outflow made itself and the tight closing of connector top outfall with jack-up taper manhole cover in the pipeline, was enclosed in sewage following and can not refluxes.

The utility model is compared with prior art has following characteristics:

1, prevent the stink diffusion, result of use is good, can be widely used in various ponds use in the building, also can install the transformation of existing pond;

2, strainer can leach the foreign material that sewer pipe is difficult for discharge;

3, water sealed tank adopts circular design, and promptly adopting the cross section is the annular seal-water tank of semicircle, and foreign material are difficult for being deposited in the water sealed tank, even there is deposit to stop up in the water sealed tank, do not dismantle just yet and can remove, and when removing deposit, do not leak the foreign odor smell in the building water channel;

When 4, the water trunk line stops up down, can prevent that sewage from flowing backwards;

5, simple in structure, can adopt the manufacturing of casting method, with low cost;

6, building can use one tunnel draining, saves water pipe, reduces simultaneously to apply not have the sewer pipe workload, reduces the cost that builds a house;

7, owing to be straight tube shape, promptly be convenient to install, save the interior space again, make indoor neat and artistic.
