Description

Technical Field

[0001] The utility model relates to the field of oil production, in particular to an oil production device with the function of improving quality and efficiency. Background Art

[0002] During the oil extraction process, especially when the oil well passes through a stratum containing sand, the sand may be pumped to the ground along with the oil. After the sand-containing oil is successfully extracted, it is necessary to filter the sand in time, otherwise it will affect the subsequent processing and use of the oil.

[0003] A Chinese patent discloses a sand filter device for oil production (authorization announcement number CN213313552U). The utility model effectively avoids the problem that sand and gravel easily clog the surface of the filter element and thus requires frequent cleaning of the filter element, affecting the filtering efficiency, thereby improving the sand filtering efficiency.

[0004] Since the above-mentioned device sets the feed pipe directly above the rotating cone head, the sand-containing oil will directly impact the rotating cone head under the action of gravity and external conveying force, which will not only increase the resistance of the rotating motor to drive the cleaning plate to rotate through the rotating cone head, but also increase the burden of the filter supporting the rotating motor and the rotating cone head.

[0005] Therefore, an oil production device with the function of improving quality and efficiency is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an oil production device with the function of improving quality and efficiency in order to solve the above problems, thereby improving the problem of heavy operating burden of the oil production sand filtering device with the function of improving quality and efficiency.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme, which is an oil production device with the function of improving quality and efficiency, including: a mounting cylinder, a filter element is placed inside the mounting cylinder, the bottom of the mounting cylinder is fixedly connected and communicated with a discharge pipe arranged on the inner side of the filter element, the top of the mounting cylinder is plugged with a sealing cover, the surface of the sealing cover is fixedly connected and communicated with a feed pipe; a cleaning device, the cleaning device is installed between the filter element and the sealing cover.

[0008] Preferably, the cleaning device includes a rotating seat fixedly connected to the inner top wall of the sealing cover, the surface of the rotating seat is rotatably connected to a rotating sleeve, the surface of the rotating sleeve is fixedly connected to a ring-shaped paddle, the feed pipe is arranged on one side of the rotating sleeve, the opening of the feed pipe faces the paddle arranged on the side of the rotating sleeve, and the bottom of the rotating sleeve is fixedly connected to cleaning plates that are evenly distributed and in contact with the filter element.

[0009] Preferably, evenly distributed balls are embedded and installed on the inner side of the rotating sleeve, and the balls are in contact with the rotating seat, which can reduce the rotational resistance of the rotating sleeve and make the entire cleaning device run more smoothly.

[0010] Preferably, a fixed ring frame is fixedly connected to the surface of the rotating sleeve, and the top of the cleaning plate is fixedly connected to the fixed ring frame, which can connect all the paddles into one, so as to improve the impact resistance of the paddles.

[0011] Preferably, an electric cylinder is fixedly connected to the surface of the mounting cylinder, and the output shaft of the electric cylinder is fixedly connected to the sealing cover; there are two electric cylinders, and the two electric cylinders are symmetrically distributed on both sides of the sealing cover, which can reduce the difficulty of opening the sealing cover for the staff, so as to facilitate the staff to subsequently maintain the interior of the mounting cylinder.

[0012] Preferably, the bottom of the rotating seat is threadedly connected with a threaded column, and the bottom of the threaded column is fixedly connected to the filter element, which not only connects the filter element and the rotating seat into one, allowing the electric cylinder to lift the filter element to the outside of the mounting cylinder, but also the threaded design allows the staff to easily remove the filter element, reducing the burden on the staff to maintain the filter element.

[0013] Preferably, a sealing gasket plugged into the sealing cover is fixedly connected to the top of the mounting cylinder, and the inner diameter of the sealing gasket is larger than the inner side of the mounting cylinder, which can reduce the probability of oil leakage along the gap between the mounting cylinder and the sealing cover to reduce oil waste.

[0014] The beneficial effects of the utility model are:

[0015] 1. The cleaning device can first contact with the sand-containing oil before the filter element. This can not only reduce the probability of the filter element being directly impacted by the sand-containing oil, thereby reducing the operating burden of the filter element, but also can divide and guide the sand-containing oil to more areas, making the filter element more evenly stressed, further reducing the operating burden of the filter element;

[0016] 2. The cleaning device can actively rotate under the impact of sand-containing oil and scrape off the sand and gravel adhering to the surface of the filter element. This can reduce the filtering burden of the filter element to ensure the effective passage rate of the oil, thereby achieving the effect of improving quality and increasing efficiency. This does not require a separate electric power source for the operation of the cleaning plate. At the same time, the cleaning device can change the speed according to the flow rate of the sand-containing oil to meet the filtering and cleaning needs of different flow rates, further ensuring the effect of improving quality and increasing efficiency.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-5 As shown, an oil production device with the function of improving quality and increasing efficiency comprises: a mounting barrel 1, a filter element 2 is placed inside the mounting barrel 1, the bottom of the mounting barrel 1 is fixedly connected and communicated with a discharge pipe 3 arranged on the inner side of the filter element 2, a sealing cover 4 is plugged into the top of the mounting barrel 1, and the surface of the sealing cover 4 is fixedly connected and communicated with a feed pipe 5; a cleaning device 6, the cleaning device 6 is installed between the filter element 2 and the sealing cover 4, the filter element 2 and the cleaning plate 64 used in the present application are the same in structure, material and shape as the filter screen frame and the scraper in the comparative case, so the filter element 2 and the cleaning plate 64 can play the same role as the filter screen frame and the scraper in the comparative case; an electric cylinder 7 is fixedly connected to the surface of the mounting barrel 1, and the output shaft of the electric cylinder 7 is fixedly connected to the sealing cover 4; the number of the electric cylinders 7 is two, and the two electric cylinders 7 are symmetrically distributed on both sides of the sealing cover 4; the top of the mounting barrel 1 is fixedly connected with a sealing gasket 8 plugged into the sealing cover 4, and the inner diameter of the sealing gasket 8 is larger than the inner side of the mounting barrel 1;

[0025] When the staff needs to clean the sand and gravel retained on the surface of the filter element 2, the staff only needs to manually control the two electric cylinders 7 to extend upward at the same time, the electric cylinder 7 drives the sealing cover 4 to rise, the sealing cover 4 drives the rotating seat 61 to rise, the rotating seat 61 drives the threaded column 67 to rise, and the threaded column 67 drives the filter element 2 to rise until the filter element 2 is completely removed from the mounting cylinder 1. Then the staff can clean the filter element 2 normally, and the staff can rotate the filter element 2 in the corresponding direction, and the filter element 2 drives the threaded column 67 to move outward along the rotating seat 61 spirally until the rotating seat 61 is separated from the threaded column 67. Then the staff can remove the filter element 2, making it more convenient for the staff to maintain or replace the filter element 2.

[0026] like Figure 3 , Figure 4 and Figure 5 As shown, the cleaning device 6 includes a rotating seat 61 fixedly connected to the inner top wall of the sealing cover 4, a rotating sleeve 62 is rotatably connected to the surface of the rotating seat 61, a ring-shaped paddle 63 is fixedly connected to the surface of the rotating sleeve 62, a feed pipe 5 is arranged on one side of the rotating sleeve 62, and the opening of the feed pipe 5 faces the paddle 63 arranged on the side of the rotating sleeve 62, and a cleaning plate 64 that is evenly distributed and in contact with the filter element 2 is fixedly connected to the bottom of the rotating sleeve 62; evenly distributed balls 65 are embedded and installed on the inner side of the rotating sleeve 62, and the balls 65 are in contact with the rotating seat 61; a fixed ring frame 66 is fixedly connected to the surface of the rotating sleeve 62, and the top of the cleaning plate 64 is fixedly connected to the fixed ring frame 66; a threaded column 67 is threadedly connected to the bottom of the rotating seat 61, and the bottom of the threaded column 67 is fixedly connected to the filter element 2.

[0027] When the utility model is in use, the staff first connects the external oil pipeline for conveying sand-containing oil with the feed pipe 5, and then the sand-containing oil can be conveyed to the feed pipe 5 through the oil pipeline, and the feed pipe 5 guides the sand-containing oil to the inner side of the sealing cover 4. In this process, the sand-containing oil impacts the paddle 63 opposite to it in advance, and the paddle 63 drives the rotating sleeve 62 to rotate, and the rotating sleeve 62 drives all the paddles 63 to rotate synchronously. At this time, the two adjacent paddles 63 cooperate to divide the sand-containing oil entering the sealing cover 4, which can guide the sand-containing oil to more areas, and this can reduce the probability that the filter 2 is directly impacted by the sand-containing oil, so as to reduce the operating burden of the filter 2, and then the sand-containing oil passes through the filter 2 in the process of falling, and the filter 2 filters out the sand and gravel in the sand-containing oil, so that the clean oil is discharged through the discharge pipe 3;

[0028] During the rotation of the rotating sleeve 62, the rotating sleeve 62 synchronously drives the cleaning plate 64 to rotate. The cleaning plate 64 rotates to scrape off the sand and gravel adhered to the surface of the filter element 2, which can reduce the filtering burden of the filter element 2 to ensure the effective passage rate of the oil, thereby achieving the effect of improving quality and increasing efficiency. The cleaning plate 64 is passively rotated by the impact of the sand-containing oil, which does not require a separate electric power source for the operation of the cleaning plate 64. At the same time, it can change the rotation speed according to the flow rate of the sand-containing oil to meet the filtering and cleaning needs of different flow rates, further ensuring the effect of improving quality and increasing efficiency.

[0029] It should be noted that the electric cylinder 7 in the above description is a device with relatively mature application of existing technology. The specific model can be selected according to actual needs. At the same time, the electric cylinder 7 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
