Vacuum system

Abstract

The invention relates to a vacuum system which comprises a plurality of drainage sources, a plurality of vacuum conveying pumps, a sewage collecting part and a control center. Each sewage source comprises a drainage pool with a sewage outfall, a vacuum release valve, a vapor integrated double electromagnetic valve and a control device; and the sewage outfall of the drainage pool is connected with a discharge pipe of the sewage source by the vacuum release valve. The discharge pipe of the sewage source is connected with a sewage suction pipe by an isolation ball valve; the sewage suction pipe is connected with an inlet pipe of each vacuum conveying pump; and an outlet pipe of each vacuum conveying pump is connected with a sewage discharge pipe which is connected to the sewage collecting part. A pressure detection device in electric connection with the control center is arranged on the sewage suction pipe; and the vacuum conveying pump and the control center are in electric connection. In the vacuum system, the control center carries out intelligent control that one or a plurality of the vacuum conveying pumps are opened according to the detected vacuum degree of the sewage suction pipe; the vacuum system can ensure the vacuum degree of the sewage suction pipe to make sewage discharging smooth, effectively saves energy, has simple control, reduces cost, improves the reliability of the system and is convenient to maintain.

Description

technical field [0001] The invention relates to a sewage or sewage discharge system, in particular to a vacuum system. Background technique [0002] Chinese patent document 01123161.0 discloses "a vacuum system", which relates to a method for transporting sewage using a vacuum system. device. For a reliable operating system, this method employs a rotary lobe pump to create a vacuum through which the sewage is transported to the sewage collection or discharge space. This kind of system requires a lot of electric valves to control. For each additional rotary lobe pump, at least two sets of electric valves must be added, and when the rotary lobe pump is used for sewage discharge, the rotary lobe pump must be changed while controlling the electric valve. The direction of rotation, as long as any valve fails, it will cause the sewage to overflow. On the other hand, rotary lobe pumps are prone to clogging when encountering larger, harder dirt or very soft paper or silk products...

AI Technical Summary

Problems solved by technology

[0004] The invention also solves the technical problems that the rotary cam pump is prone to blockage, the pressurization capacity is not strong enough, the suction force and discharge force are not ideal enough, and the small-diameter non-gravity pressurized discharge cannot be realized, which is not conducive to the layout and construction of the sewage system pipeline. ;Provide a method that can grind and pulverize the dirt, effectively solve the problem of dirt clogging, expand the scope of sewage treatment, improve the suction force, discharge force and pressurization capacity, realize small-caliber non-gravity pressurized discharge, and facilitate the installation of sewage system pipelines A vacuum system for layout and construction
