AI Technical Summary

Technical Problem

Oil spills into the environment when residual oil is left untreated during the use of the oil pumping arm, causing pollution and economic losses, and affecting ecological balance and corporate profits.

Method used

An automatic residual oil recovery and delivery arm is designed, comprising a residual oil recovery mechanism, a guide pipe, a pneumatic butterfly valve, and an explosion-proof pump. The residual oil is guided into the recovery tank by an inclined guide ramp and an oleophobic coating. Gravity and centrifugal force are used to accelerate the recovery process, and the recovery progress is monitored by a liquid level sensor.

Benefits of technology

It effectively collects residual oil, prevents leaks, protects the ecological environment, reduces pollution risks, lowers production costs, improves economic efficiency, and complies with environmental regulations.

Abstract

The utility model relates to an automatic residual oil recovery oil transfer arm, relates to the technical field of oil transfer arms, and aims to solve the problem of residual oil products of the oil transfer arm. The automatic residual oil recovery oil transfer arm comprises a stand column, an inner arm connected with the stand column, an outer arm, an inner arm support and an outer arm support, and a residual oil recovery mechanism is arranged on the side, close to the stand column, of the inner arm support; the residual oil recovery mechanism comprises a recovery box, a flow guide pipe, a pneumatic butterfly valve and an explosion-proof pump, the recovery box is arranged on the supporting side wall of the inner arm, the pneumatic butterfly valve is arranged on the flow guide pipe, the two ends of the flow guide pipe are communicated to the recovery box and the elbow of the inner arm respectively, a flow guide ramp is arranged at the inlet end of the flow guide pipe, and the explosion-proof pump is arranged on the flow guide ramp. The flow guide ramp extends to the inner wall of the pipeline of the inner arm, and the anti-explosion pump is communicated to the bottom of the recycling box. The oil transfer arm has the advantages that oil products remaining on the inner arm, the outer arm and other parts of the oil transfer arm after oil loading and unloading operation is finished can be effectively collected, and oil product waste of enterprises is reduced.
