Description
Technical field
The utility model belongs to urban construction technical field, refers in particular to the prefabricated well head of a kind of sewer.
Background technology
Municipal sewage system is sewage effluent, the indispensable facility of anti-flood, in sewer process of deployment, between certain distance, all can arrange well head, and one is the excretion facilitating rainwater, and two is convenient for maintaining and dredging.And the construction of current sewer well head, be all build at the enterprising windrow of reserved opening and build, the engineering time is long, and efficiency is low, and to wait solidify completely after could use; In addition, under the long-term closed state of the mud and sewage in sewer, can produce biogas, biogas is inflammable, if because of carelessness the thing of band flare is fallen into sewer, easily sets off an explosion, produces safely great threat to civic.
Summary of the invention
The purpose of this utility model is to provide one and directly can installs, come into operation fast, the prefabricated well head of sewer of discharge biogas.
The purpose of this utility model is achieved in that the prefabricated well head of sewer, comprise the base of horizontal water conservancy diversion and the vertical shaft of draining, described base and vertical shaft are integral type structure, described base is provided with flow-guiding mouth, for connecting the pipeline being laid on underground, wherein, described vertical shaft is provided with exhaust opening I and exhaust opening II, described exhaust opening I and exhaust opening II are all perpendicular to the wall of described vertical shaft, the inwall of described vertical shaft is provided with extract duct I, the outer wall of described vertical shaft is provided with extract duct II, described extract duct I one end extends in described base, the other end is communicated with described exhaust opening I, described exhaust opening I place is provided with exhaust fan, and described extract duct II one end is communicated with exhaust fan, and the other end is communicated with exhaust opening II.
According to the upper described prefabricated well head of sewer, wherein, described exhaust opening II is arranged on the well head place of described vertical shaft, and be positioned at the top of described exhaust opening I, the biogas be deposited in sewer can be displaced into well head, due to biogas lta, the biogas being discharged into well head can directly be discharged along well head.
According to the upper described prefabricated well head of sewer, wherein, the air inlet port of described extract duct I and described exhaust opening II are provided with guard, prevent foreign material from entering, affect exhaust effect.
According to the upper described prefabricated well head of sewer, wherein, the diameter of the air inlet port of described extract duct I is greater than the diameter in extract duct I stage casing, effectively can improve the efficiency absorbing biogas.
According to the upper described prefabricated well head of sewer, wherein, the air inlet port in the vertical direction of described extract duct I, higher than described flow-guiding mouth, prevents sewage from flooding the air inlet port of extract duct I, affects normal exhaust.
The utility model gives prominence to compared to existing technology and useful technique effect is: directly can install, improve efficiency of construction, and possess scavenging action, in time by the firedamp drainage in sewer, biogas can be avoided to deposit, leave potential safety hazard.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 10-base, 11-vertical shaft, 12-flow-guiding mouth, 13-extract duct I, 14-exhaust opening I, 15-extract duct II, 16-exhaust opening II, 17-exhaust fan, 18-air inlet port.
Detailed description of the invention
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, see Fig. 1: the prefabricated well head of sewer, comprise the base 10 of horizontal water conservancy diversion and the vertical shaft 11 of draining, described base 10 and vertical shaft 11 are integral type structure, described base 10 is provided with flow-guiding mouth 12, for connecting the pipeline being laid on underground, wherein, described vertical shaft 11 is provided with exhaust opening I 14 and exhaust opening II 16, described exhaust opening I 14 and exhaust opening II 16 are all perpendicular to the wall of described vertical shaft 11, the inwall of described vertical shaft 11 is provided with extract duct I 13, the outer wall of described vertical shaft 11 is provided with extract duct II 15, described extract duct I 13 one end extends in described base 10, the other end is communicated with described exhaust opening I 14, described exhaust opening I 14 place is provided with exhaust fan 17, and described extract duct II 15 one end is communicated with exhaust fan 17, and the other end is communicated with exhaust opening II 16.The exhaust fan preset and exhaust passage, in time by the firedamp drainage in sewer, can avoid biogas to deposit, leave potential safety hazard, as shown by the arrows in Figure 1, during for exhaust, and the path of gas circulation.
Further optimization, described exhaust opening II 16 is arranged on the well head place of described vertical shaft 11, and is positioned at the top of described exhaust opening I 14, the biogas be deposited in sewer can be displaced into well head, due to biogas lta, the biogas being discharged into well head can directly be discharged along well head.
Further optimization, the air inlet port 18 of described extract duct I 13 and described exhaust opening II 16 is provided with guard, prevents foreign material from entering, affect exhaust effect.
Further optimization, the diameter of the air inlet port 18 of described extract duct I 13 is greater than the diameter in extract duct I 13 stage casing, effectively can improve the efficiency absorbing biogas.
Further optimization, air inlet port 18 in the vertical direction of described extract duct I 13, higher than described flow-guiding mouth 12, prevents sewage from flooding the air inlet port 18 of extract duct I 13, affects normal exhaust.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
