Description

Water excretion machine under the environment-friendly type

The utility model relates to a kind of urban construction facility, particularly a kind of novel excretion machine that is used for the transporting municipal wastewater.

The blowdown apparatus that use in existing city adopts continuity traditional old-fashioned cast iron double-edged fine-toothed comb for many years basically, it is installed on the roadside on municipal street road, though it can play certain blowdown effect, but it does not catch up with the development need of existing urban construction far away, it mainly shows as follows: one, spacing between the double-edged fine-toothed comb is less than normal in addition because the area of cast iron double-edged fine-toothed comb own is just little, rainy day, the weeds that go up in the street, leaf, article such as polybag very easily block its hand-hole, so, it is little long-pending little that at present existing most of block ubiquity light rain, the big ponding of heavy rain, the not only monster but also strange phenomenon of the long-pending full water of heavy rain.Ponding has brought many adverse effects for the traffic in city and pedestrian's personal safety, because traffic accident and personal injury that it caused are of common occurrence; Two, the foreign material of carrying secretly in the following water such as mud only can partly be deposited in the shaft bottom of double-edged fine-toothed comb below, majority enters pipe network with flowing water, cause the obstruction of pipe network so on the one hand easily, some finally also can enter river, lake (big rainy day on the other hand, the water yield is big, and is when current are anxious, all the more so, so accelerate the sediment accumulation rate of river and lake, increased the weight of the pollution and the negative oxidation of river and lake; Three, filter down owing to it only has that water does not have sealing function, return on the stink in the sewer, around the following well then foul smell overflow, the result not only extinguishes cheerfulness and enthusiasm, and has polluted air, has reduced air quality, thereby gives transmission of disease and the popular condition of having created.

The purpose of this utility model provides and a kind ofly can overcome effectively that the problems referred to above take place, good filtration effect, and desilting is convenient, water excretion machine under the novel environment-friendly that can effectively prevent to return on the peculiar smell in the sewer.

The purpose of this utility model is achieved in that it comprises housing, housing is made of body cavity and side wall body two parts, body cavity communicates by guiding gutter with the side wall body, the endoceliac port of export of guiding gutter is the wedge shape inclined-plane, the inclined-plane loam cake is with watertight shutter, and the body lumen wall of watertight shutter and guiding gutter top is rotationally connected; Housing upper end open place is provided with well lid, and lower ending opening is provided with filter basket, and the side wall body is provided with protecting cover near a side of well lid, has drain hole on it.

When using the utility model, the following water inlet place that is fixed in the roadside gets final product; Rainwater is through in the drain hole inflow side body of wall on the protecting cover, bigger foreign material such as branch are blocked in outside the protecting cover in the rainwater, rainwater in the approaching side body of wall flows into guiding gutter, the attached watertight shutter thereon of lid is washed open in the filter basket that flows into the body cavity lower end, filtration through filter basket, less foreign material such as weeds are further filtered in the rainwater, thereby guarantee the relative cleaning that enters flowing water in the sewer pipe net, have alleviated the pollution to rivers, lake environment; After draining finishes, watertight shutter under the effect of gravity automatically lid invest on the inclined-plane of guiding gutter body cavity inner outlet end, thereby it is airtight, prevent peculiar smell in the sewer on return; Behind long-term use the utility model, can open well lid, the dirt that wherein be toppled in the taking-up of the filter basket on the body cavity lower port get final product, very convenient.

The utility model advantage: the first, rainwater is to enter by the drain hole on the protecting cover, and drain hole adopts edge-on structure, and the aperture is bigger, therefore is difficult for ponding, and draining is unobstructed; The second, watertight shutter is when anhydrous inflow, can be under action of gravity automatically with the port closing of guiding gutter, thereby can effectively prevent to return on the peculiar smell in the sewer, guarantee the sanitation and hygiene of air ambient; Three, endoceliac filter basket can be carried out secondary filter by following water, greatly reduce the content that enters the solid dirt of waste water in the sewer pipe net, alleviated pollution, simultaneously lake, river, its desilting is convenient, regularly opens the dirt that well lid topples in the filter basket and can finish whole process.

Below in conjunction with accompanying drawing in detail the utility model is described in detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the A-A of Fig. 1 is to the structure sectional view.

As shown in the figure, the utility model comprises housing 1, the housing 1 of present embodiment adopts the cube structure of upper and lower opening, housing 1 is made of body cavity 9 and side wall body 4 two parts, body cavity 9 communicates by guiding gutter 6 with side wall body 4, the port of export in guiding gutter 6 body cavitys 9 is the wedge shape inclined-plane, and the inclined-plane loam cake is with watertight shutter 7, and watertight shutter 7 is rotationally connected by rotating shaft 5 with the body lumen wall of guiding gutter 6 tops; Housing 1 upper end open place is provided with well lid 2, and lower ending opening is provided with filter basket 8, and side wall body 4 is provided with protecting cover 10 near a side of well lid 2, has drain hole 3 on it.
