Embodiment 1

[0083] Such as Figure 5a , 5b As shown, a vacuum sewage conveying system for crossing obstacles, wherein the obstacles use trenches and buildings as application scenarios, but not limited to the above two scenarios, the system includes vacuum sewage pipelines passing through the obstacles (by Reference numerals are 04, 07, 08, 09, 10, the air pipeline 05 and the ventilation pipeline (the pipeline consisting of 12, 13, 14, 15) connected with the vacuum sewage pipeline road), respectively installed on the air pipeline 05 and the valve assembly on the ventilation pipeline (consisting of reference numerals 06, 16), and a controller 19 for controlling the action of the valve assembly; wherein one end of the air pipeline 05 is connected to the vacuum sewage The pipelines are connected, and the other end extends above the ground; the ventilation pipeline connects the upstream end and the downstream end of the vacuum sewage pipeline.

[0084]The vacuum sewage pipeline includes the ...

Embodiment 2

[0095] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the blowdown valve on the air pipeline 05 and the ventilation pipeline, and the controller 19 for switching on and off the controller 19 are all located below the ground in a sealed storage with waterproof, moisture-proof and freeze-proof functions. In the chamber 20; and in the present embodiment, as Figure 5c and 5d As shown, the blowdown valve on the air pipeline 05 and the ventilation pipeline (the pipeline formed by reference numerals 12, 13, 14, 15), and the controller 19 for controlling on-off are all located above the ground with waterproof, moisture-proof and freeze-proof In the sealed storage room 20 of the function; the former setting mode is convenient for passage, and the latter setting mode is convenient for disassembly and maintenance.

[0096] In the above two embodiments, the application scenarios of trenches and buildings are used, and no distinction will be made in the ...

Embodiment 3

[0099] Such as Figure 5e As shown, a vacuum sewage conveying system for crossing obstacles, including a vacuum sewage pipeline (composed of reference signs 04, 07, 08, 09, 10) passing through the obstacle, and a vacuum sewage pipeline The air pipeline 05 and the ventilation pipeline (composed of reference signs 21, 22, 23, 24), which are connected to the air pipeline 05, and the valve assembly respectively installed on the air pipeline 05 and the ventilation pipeline (represented by reference symbols 25, 26, 27, 28, 35), and a controller 19 for controlling the action of the valve assembly.

[0100] Among them, the vacuum sewage pipeline includes the sewage pipeline A04 connected in sequence along the sewage flow direction and arranged upstream, the sewage pipeline B07 that is close to the obstacle to the upstream side and bent downward, and the sewage pipeline installed below the obstacle C08, the sewage pipeline D09 that is bent toward the downstream side near the obstacle,...

Abstract

The invention relates to a vacuum sewage conveying system for crossing an obstacle. The vacuum sewage conveying system comprises a vacuum sewage pipeline penetrating through the lower side of the obstacle, an air pipeline and a ventilation pipeline which communicate with the vacuum sewage pipeline, valve assemblies mounted on the air pipeline and the ventilation pipeline, and a controller used for controlling the valve assemblies to act; one end of the air pipeline communicates with the vacuum sewage pipeline, and the other end extends above the ground; the ventilation pipeline communicates with the upstream end and the downstream end of the vacuum sewage pipeline. The vacuum sewage conveying system for crossing the obstacle relates to a specific technology for avoiding pipeline blockage caused by vacuum degree reduction and solid garbage precipitation in sewage when the sewage passes through the certain obstacle on the vacuum sewage pipeline, so that the conveying distance and the conveying efficiency of the vacuum sewage conveying system are improved, pipeline blockage is reduced to a certain extent, and the system reliability is improved.

Description

technical field [0001] The invention relates to a technical field of vacuum sewage conveying system applied between a vacuum sewage collection system and a vacuum sewage treatment system, wherein the vacuum sewage collection system is the source of vacuum sewage generation or the front end of vacuum sewage collection, the vacuum sewage treatment system and the sewage after The present invention particularly relates to a vacuum sewage conveying system for crossing obstacles. Background technique [0002] The vacuum sewage collection and transportation system (referred to as the vacuum sewage system) refers to the vacuum generated by the vacuum pump station (the vacuum here is not absolute vacuum, but a state of decompression or lower than atmospheric pressure) and atmospheric pressure. The pressure difference to collect and transport sewage system. [0003] Taking the vacuum sewage conveying system in the prior art as an example, its existing defects are described in detail,...
