Waste oil and water conveying device for compressed air station

Abstract

The invention relates to a waste oil and water conveying device for a compressed air station, which comprises a storage container. Two ends of the storage container are respectively provided with an oil inlet and an oil outlet; the top of the storage container is also provided with a compressed air inlet and a liquidometer mounting interface; the bottom of the storage container is provided with a drain outlet; the oil inlet is provided with a first electrically operated valve; the oil outlet is provided with a second electrically operated valve; the compressed air inlet is provided with a third electrically operated valve; the a liquidometer is arranged at the liquidometer mounting interface; the drain outlet is provided with a fourth electrically operated valve; the first electrically operated valve, the second electrically operated valve, the third electrically operated valve, and the liquidometer are controlled by a centralized control system; and the first electrically operated valve is normally open, the second electrically operated valve is normally closed, the fourth electrically operated valve is normally closed, and the third electrically operated valve is normally closed. The waste oil and water conveying device has the advantages of simple structure, convenient operation and light environmental pollution, and conveys pressureless waste oil and water to higher positions by utilizing the kinetic energy of compressed air.

Description

technical field [0001] The invention relates to a waste oil and water conveying device of a compressed air station, in particular to a waste oil and water collecting device which utilizes the kinetic energy of compressed air to convey waste oil and water without pressure to a higher position. Background technique [0002] At present, the waste oil and water of many equipment (such as large air compressors for blast furnaces) are discharged without pressure. For the collection of these waste oils and water, the usual design method is to connect the waste oil and water to the sewage pipe or lead to the waste oil and water collection tank at a lower position, and then treat them regularly. If it is directly connected to the sewage pipe, it will pollute the environment. If the latter treatment method is used, since the instantaneous discharge of waste oil and water is small, it is impossible to pump oil and water on the pipeline. At the same time, due to the large volume of th...

Problems solved by technology

If it is directly connected to the sewage pipe, it will pollute the environment

If the latter treatment method is adopted, due to the small instantaneous discharge of waste oil and water, it is impossible to pump oil and water on the pipeline

At the same time, due to the large volume of the waste oil and water collection tanks and the low-level requirements, usually the waste oil and water collection tanks can only be placed in pits that are lower than the equipment level

This not only increases the amount of construction work, but also brings inconvenience to future operations.
