Energy-saving fully-automatic normally-lifting vacuum device

Abstract

The invention discloses an energy-saving fully-automatic normally-lifting vacuum device and relates to the technical field of vacuum water diversion of pipelines or containers. A vacuum tank is connected with a water ring vacuum pump through a pipeline, a manually operated valve and a non-return valve are arranged on the pipeline for connecting the vacuum tank and the water ring vacuum pump, the water ring vacuum pump is connected with a circulating water tank through a water discharge pipeline of the vacuum pump and a water suction pipe of the vacuum pump, the water suction pipe of the vacuum pump is positioned below the liquid level in the circulating water tank, a liquid level switch is arranged above the circulating water tank, a tap water pipe is connected to the circulating water tank, an electromagnetic valve is arranged on the tap water pipe, the circulating water tank is simultaneously provided with an overflow pipe, and an electrically operated valve is arranged at the bottom of the overflow pipe. Working water of the vacuum pump can be circularly utilized, so that water resources are saved; and as a water diversion pipeline is kept at a full water state at any time, the production safety is improved, a fully-automatic operating mode is achieved and the workload of operators is reduced.

Description

Technical field: [0001] The invention relates to the technical field of vacuum water diversion of pipelines, equipment or containers, in particular to a water-saving automatic constant-hanging vacuum device. Background technique: [0002] With the progress of society and the development of industry, industrial equipment spreads all over our country's national economy. Many water wading equipment requires constant vacuum during operation, that is, to ensure that the corresponding cavity of the equipment is filled with water at all times. For example, the suction pipe and pump body must be filled with water during the startup and operation of the centrifugal pump; another example is the submerged water supply ultrafiltration membrane system. During the start-up and operation process, the membrane tube and the water production pipeline are required to be filled with water; for example, during the operation of various siphon tubes, the pipeline is also required to be full of wat...

AI Technical Summary

Problems solved by technology

At present, most of the constant vacuum equipment on the market are water ring vacuum pumps, which use tap water as the working medium, cooperate with the vacuum tank and liquid level control. The waste of the working medium of the vacuum pump is contrary to my country's energy-saving and emission-reduction policies
