Safe, environmental protection and energy-saving type oil-filling device

Abstract

The present invention provides a safe, environmental protection, energy-saving type oil-filling device which at least consists of a double-wall oil-storage tank. The separating explosion-proof materials are respectively filled in the tank inner cavity and the tank wall interlayer. The oil outlet pipe of the oil-storage tank is connected with the oil-filling machine. A skid body is set up under the oil-storage tank and the oil-filling machine. A hood body is set up on the skid body. The oil-filling machine is a split type oil-filling machine, which consists of a digital electronic display, an oil pump case body and a filling gun. The digital electronic display and the filling gun are set up on the outer side of hood body wall. The oil pump case body is set up in the space formed by inside of the hood body and outside of the oil-storage tank and fixed on the skid body. The oil outlet pipe of the oil-storage tank is connected on the oil pump case body. The oil outlet hose on the oil pump case body is connected to the filling gun through the wall hole of the hood body. An oil gas recovery device is set up on the oil-storage tank, which consists of a breather valve set up on the oil-storage tank and connected with the oil-storage tank through a breather valve pipeline. A triple valve is mounted on the breather valve pipeline. One end of the triple valve is connected with the oil gas recovery hose. During the process of filling oil from the tank car to the oil-storage tank, the filler neck of the oil gas recovery hose is connected with the joint of the oil gas recovery hose of tank car. In the double-wall oil-storage tank of present invention, split type oil-filling machine is fixed on the skid body, and separating explosion-proof materials are filled in the tank wall interlayer and in the inner cavity, so that the floor area is greatly reduced and the intrinsic safety of oil-storage tank is guaranteed. The hood body on the skid body may be designed in diversified moldings and patterns according to the requirements of peripheral environment, so as to enhance the sense of safety. Since the arrangement of the oil gas recovery device the process of filling oil may achieve the enclosed recovery of oil gas, avoid the volatilization of oil gas in oil-storage tank and effectively reduce the contamination and damage to the atmosphere and saving the energy, thus the invention indeed realize the object of safety, environmental protection, energy conservation and decreasing of energy consumption.
