Setting in the lower section of collecting tank 1, to ensure that the sewage collected in collecting tank 1 can be directly discharged into cesspool 6 by gravity.
For collecting tank 1, structure design palpus satisfaction can collect whole by steel wire for logging and packing gap location
The sewage of spilling is based on the purpose, as an example, as shown in Figure 1 and Figure 2, the collecting tank 1 can include: slot ontology
101, it is located at 101 top of slot ontology, and the installation step 102 extended radially outward.Wherein, installation step 102 in clip
On the roof of head M, and there is the first sealant 7 between installation step 102 and the roof of hoop M.
In above-mentioned collecting tank 1, installation step 102 serve not only as mounting structure make collecting tank 1 steadily seat in water injection well well
At the top of the hoop M of mouth, and as edge collection structure, to collect the sewage by flowing down on lubricator N outer wall.It is close by first
Sealing 7 prevents sewage from overflowing pollution well head by the gap location to seal the gap between collecting tank 1 and hoop M.
In order to further increase the leakproofness between collecting tank 1 and hoop M, formation secondary seal is further, such as attached
Shown in Fig. 1, there is the second sealant 8 between the slot ontology 101 of collecting tank 1 and the side wall of hoop M.
Wherein, the first sealant 7 and the second sealant 8 can use the form of sealing rubber ring.
In addition, for collecting tank 1, in order to ensure the sewage overflowed by each position can be collected by catch basin
It arrives, collecting tank 1 can be made to be set as a circle around hoop M, for example, as shown in Fig. 2, slot ontology 101 is to enclose to be set to card
Bind round the annular groove outside head M；Installation step 102 is the circular ring shape plate connecting with the inner ring roof of annular groove, wherein slot sheet
Both body 101 and installation step 102 can be integrally formed, and on the premise of ensuring tightness, while ensure the strong of collecting tank 1
Degree.
Collecting tank 1 can be prepared using rigid plastics, so be not only convenient for forming, and make its stabilizing base convenient for improving
In on hoop M.
Sewage for the ease of collecting in collecting tank 1 can be quickly and completely discharged into cesspool 6, and the utility model is implemented
In example, the slot bottom of collecting tank 1 is oblique, and connect and be connected at blowdown pipe nipple 4 and the most short position of slot bottom.Collecting tank 1
The gradient of slot bottom can be 1:10, for example, the slot bottom of collecting tank 1 can be made radially to incline gradually downward from the inside to the outside
Tiltedly, and until reach most short at the link position of slot bottom and lateral wall.
Blowdown pipe nipple 4 is connect with the upper end of sewage pipe 5, and the lower end of sewage pipe 5 stretches in cesspool 6, when sewage water flow
When more rapid, certain impact force may be caused, to sewage pipe 5 in order to ensure the connection between blowdown pipe nipple 4 and sewage pipe 5
Tightness, in the utility model embodiment, sewage pipe 5 is sheathed on outside blowdown pipe nipple 4, is had on the outer wall of blowdown pipe nipple 4 thick
Rough structure ensures that sewage pipe 5 is steady using the increased frictional force for increasing the frictional force between blowdown pipe nipple 4 and sewage pipe 5
It is connected and is connected on blowdown pipe nipple 4.
Sewage pipe 5 can use elastic material, such as vulcanie to be prepared.In addition, above-mentioned coarse structure include but
It is not limited to: the protrusion with various geometries.As an example, which is gingival cyst of mucous gland in the newborn buckle structure, gingival cyst of mucous gland in the newborn buckle structure
The fastening dynamics between tubular part can be effectively increased.
Further, as shown in Fig. 1, liquid collector provided by the embodiment of the utility model further include: fastening clamp 9,
The fastening clamp 9 is arranged in outside sewage pipe 5, is used for clamping sewage pipe 5 and blowdown pipe nipple 4, is further ensured blowdown pipe nipple 4
It is fastenedly connected with sewage pipe 5.
In application, sewage pipe 5 can be sheathed on outside blowdown pipe nipple 4, and be arranged in fastening clamp 9 outside sewage pipe 5,
To reach fastening effect.
Above-mentioned to refer to, gate valve 2 is connect with the lower part of lubricator N, for being located at the portion below of gate valve 2 in the inner cavity lubricator N
Divide sewage, lubricator N can be unloaded, be importing directly into this part of contaminated water in collecting tank 1 by above watching out for jet pipe N.In order to make
The process is gone on smoothly, and prevents this part of contaminated water from being scattered in non-1 region of collecting tank, in the utility model embodiment, gate valve 2
Bottom end 80-100mm apart from lubricator N, for example, 80mm, 90mm, 100mm etc..
