Problems solved by technology

[0002] The traditional oil unloading method consists of an oil unloading tank, an oil unloading platform, a centrifugal pump, etc. It occupies a large area and requires a high investment; the oil unloading pool is open, the oil unloading process is not airtight, and the oil and gas volatilize seriously, which not only pollutes the environment, but also causes staff injuries. Occupational hazards, there are also safety risks such as fire and explosion; the unloading process is low in intelligence, and the labor intensity of the workers is high; the unloading method relies on the gravity of the crude oil to unload the oil, which takes a long time and low work efficiency; the unloading platform has a large slope, In natural environments such as rain, snow, ice, etc., it is difficult for unloading vehicles to be in place, and the operating conditions are harsh

Embodiment 1

[0030] Such as figure 1 As shown, a high-efficiency intelligent airtight oil unloading device involved in this embodiment includes a hose 4, a quick connector 7, a centrifugal pump 1 and an intelligent control device 2; one end of the hose 4 is airtightly connected to the tanker through the quick connector 7, The other end is connected to the centrifugal pump 1; a pressure sensor 3 is provided on the hose 4 close to the centrifugal pump 1; the pressure sensor 3 is connected to the intelligent control device 2 for controlling the start and stop of the centrifugal pump 1; the top of the tanker is provided with a breathing Valve 9 and breather valve 9 are in the normally closed state when the oil is not being unloaded, and are in the open and closed state during the oil unloading process. They are used to balance the internal and external pressure of the tank and prevent the occurrence of oil tank collapse accidents.

[0031] The hose 4 described in this embodiment is divided int...

Embodiment 2

[0052] In an oil field in Xinjiang, the daily oil discharge volume is 15 vehicles, and the daily oil discharge volume is 450 cubic meters. After the quick connector is connected, 30 tons of crude oil can be filled in the vehicle. There are 5 vehicle stoppers in this area, which can unload 5 oil at the same time. After the vehicle is in place, use the connection sealing controller to quickly and tightly connect the PU steel wire hose to the tanker through the quick connector; open the oil unloading valve of the tanker, and after the pressure sensor detects the pressure parameters, the signal is transmitted to the intelligent control device. After logical judgment, the centrifugal pump is controlled to start the pump, and the power unloading starts. During the unloading process, the breathing valve on the top of the tanker automatically opens to balance the pressure in the tank; after the liquid level in the tank reaches the lower limit of the set threshold, the pressure sensor de...

Embodiment 3

[0054] In an oil field in Shengli, the daily oil discharge volume is 30 vehicles, and the daily oil discharge volume is 900 cubic meters. After the quick connector is connected, 30 tons of crude oil can be filled in the vehicle. There are 6 vehicle stoppers in this area, which can unload 6 oil at the same time. After the vehicle is in place and the tanker is in place through the vehicle limiter, use the connection sealing controller to quickly and tightly connect the PU steel wire hose to the tanker through a quick connector; open the tanker's own oil discharge valve, and the pressure sensor detects the pressure After the parameters are set, the signal is transmitted to the intelligent control device. After logical judgment, the centrifugal pump is controlled to start the pump, and the power unloading starts. During the unloading process, the breathing valve on the top of the tanker automatically opens to balance the pressure in the tank; the liquid level in the tank reaches the...

Abstract

The invention relates to the technical field of oil unloading, and particularly relates to an efficient intelligent closed oil unloading device and method. The efficient intelligent closed oil unloading device comprises a hose, a quick coupling, a centrifugal pump and an intelligent control device; one end of the hose is connected with a tank car in a closed mode through the quick coupling, and the other end of the hose is connected with the centrifugal pump; a pressure sensor is arranged at the position, close to the centrifugal pump, of the hose and connected with the intelligent control device used for controlling the centrifugal pump to be started and stopped; and a breather valve is arranged at the top of the tank car, is in a normally-closed state in a non-oil-unloading state, is in an opening and closing state in the oil unloading process and is used for balancing the pressure inside and outside a tank and preventing the oil tank from being shrunken. The oil unloading process is achieved in a totally-closed environment under intelligent control, dissipation of volatile gas in the oil unloading process is eradicated, zero emission in the oil unloading process is achieved, the labor intensity is relieved through intelligent control over the oil unloading process, labor is reduced, and the efficient intelligent closed oil unloading device is safe, environmentally friendly, efficient and reliable.
