In this embodiment, in order to facilitate the discharge of the oil and reduce the resistance in the oil flowing process, the liquid inlet 12 and the liquid outlet 13 are disposed at two ends of the oil inlet chamber 11 in the axial direction. When the design of the pipeline is needed, the liquid inlet 12 and the liquid outlet 13 can be arranged on different straight lines or the main body 1 is provided with a corner or a similar corner structure, so long as the entering and the outflow of the oil liquid are not influenced. The above-described structure is designed to be common general knowledge, and is not limited thereto.
As an alternative embodiment, the body 1 further comprises a heating assembly 3, the heating assembly 3 being able to heat the liquid located in the oil inlet chamber 11.
The petroleum flowing out under the negative pressure condition has lower temperature and relatively high viscosity, and the viscosity of the petroleum is higher. The heating component 3 can heat the liquid flowing into the oil inlet cavity 11, so that the viscosity of the oil flowing into the oil inlet cavity 11 is reduced, the fluidity of the oil is improved, and the oil is conveniently discharged through the one-way valve 2.
The heating assembly 3 may be heated electrically to perform a heating function, in which case, in order to ensure safe use of the heating assembly 3, as an alternative embodiment, part of the heating assembly 3 is located within the oil inlet chamber 11.
It should be noted that the portion of the heating assembly 3 inserted into the oil inlet chamber 11 needs to be kept at a certain gap from the inner wall of the oil inlet chamber 11.
Alternatively, the heating element 3 may be heat-treated with a heat-conducting medium.
Specifically, the heating assembly 3 includes a heat conducting tube 32 located in the oil inlet chamber 11, where the heat conducting tube 32 is independently disposed with the oil inlet chamber 11 and is not communicated with the oil inlet chamber 11, and the heat conducting tube 32 is of a hollow structure, and a heat conducting medium can flow in the heat conducting tube 32. In this process, heat carried by the heat conducting medium can be conducted into the oil inlet cavity 11 through the pipe wall of the heat conducting pipe 32, so that the temperature of the oil in the oil inlet cavity 11 is increased, and the fluidity of the oil is improved.
It should be noted that, in order to increase the heating efficiency of the heating assembly 3, the oil can be heated as soon as possible, and the wall of the heat conducting tube 32 may be made of a material with high heat conducting efficiency.
Specifically, a certain distance exists between the part of the heat pipe 32 located in the oil inlet chamber 11 and the inner side wall of the main body 1.
In this embodiment, the heat conducting tube 32 is U-shaped, as shown in fig. 1, and two ends of the heat conducting tube 32 are located at the upper and lower sides of the liquid outlet 13.
The U-shaped design can increase the surface area of the outer sidewall of the heat pipe 32 as much as possible, thereby improving heat conduction efficiency.
In actual processing, the heat pipe 32 may be provided in other configurations according to the overall shape of the main body 1 and the volume of the oil inlet chamber 11.
It should be noted that the heat conduction pipe 32 and the main body 1 may be provided as an integral structure, or a joint between the two may be fixed by welding or the like.
In order to facilitate the replenishment and replacement of the heat transfer medium into the heat transfer tube 32, the heating assembly 3 further includes a water mixing chamber 31 in communication with the heat transfer tube 32, as shown in fig. 1.
The liquid draining member 4 is arranged outside the main body 1, one end of the liquid draining member 4 is fixedly connected with the main body 1, the other end is provided with a liquid draining interface 41 which can be communicated with the liquid outlet 13, and the water mixing cavity 31 is formed between the main body 1 and the liquid draining member 4.
At this time, the water mixing cavity 31 and the oil inlet cavity 11 are independently arranged, the heat conducting pipe 32 is positioned in the oil inlet cavity 11, and the heat conducting medium conveys heat into the oil inlet cavity 11 in a flowing mode between the water mixing cavity 31 and the heat conducting pipe 32, so that the effect of heating the oil positioned in the oil inlet cavity 11 is achieved, and meanwhile, the normal input and discharge of the liquid in the oil inlet cavity 11 are not influenced.
It should be noted that the water mixing chamber 31 is also required to be in communication with a pipeline for conveying the heat-conducting medium from the outside, and the pipeline can convey the high-temperature heat-conducting medium into the water mixing chamber 31.
When the heat-conducting medium is injected into the water mixing cavity 31, the heat-conducting medium can flow between the water mixing cavity 31 and the heat-conducting pipe 32, so that the oil in the oil inlet cavity 11 is heated, the viscosity of the oil is reduced, and the fluidity of the liquid in the oil inlet cavity 11 is improved. Since the heat transfer medium can be continuously injected into the water mixing chamber 31 through the pipeline, the excessive heat transfer medium also needs to be discharged through the associated outlet.

During the discharge of the oil through the outlet 13 and the discharge port 41, the excess heat transfer medium (in this embodiment, water) in the water mixing chamber 31 can be mixed with the oil discharged through the outlet 13 and discharged from the discharge port 41. The oil mixed with water can be further processed by an oil-water separator and the like in the subsequent processing and treatment process.
During the process of discharging the liquid, the heat-conducting medium flows towards the liquid discharge port 41 under the action of pressure, and the oil discharged through the liquid outlet 13 moves towards the liquid discharge port 41 under the action of the heat-conducting medium fluid. Ideally, the oil is discharged through the liquid discharge interface 41; in a non-ideal state, part of the oil enters the water mixing cavity 31, so that the heat conducting medium in the water mixing cavity 31 is changed from water to a water-oil mixture, and the water-oil mixture flows between the water mixing cavity 31 and the heat conducting pipe 32. Therefore, the device needs to clean the heating unit 3 after a certain period of use. When the oil increasing device is used, the oil increasing device needs to be overhauled regularly.

As an alternative embodiment, the end of the non-return valve 2 directed into the oil inlet chamber 11 is provided with an impurity filter 5.
The impurity filter 5 can be used for carrying out preliminary filtration on the extracted oil, and removing large particle impurities in the oil so as to prevent the equipment flow channel from being blocked, and simultaneously, the subsequent processing treatment on the extracted liquid is also convenient.
Specifically, the impurity filter 5 may be made of a mesh material. In order to avoid clogging of the flow path, the impurity filter 5 needs to be replaced or cleaned at intervals of about half a month when in use.
The invention also provides an oil extraction device comprising the oil booster.
The oil increasing device is required to be installed on a corresponding oil exploitation pipeline, the liquid inlet 12 and the liquid outlet 41 are respectively fixedly connected with the corresponding pipeline through structures such as the clamp head 6 and the like, so that exploitation and conveying of oil are completed, and subsequent processing treatment of the oil is facilitated.
