Description

Technical Field

[0001] This utility model relates to the technical field of oil processing equipment, and in particular to a slag removal device for oil exploration and development. Background Technology

[0002] During the oil extraction process, it is inevitable that some gravel particles will be mixed in with the crude oil. Only the crude oil is initially filtered during extraction, and a slag removal device is needed for further filtration.

[0003] For example, Chinese patent application number CN202420926411.2 discloses a slag removal device for oil exploration and development. It mentions that crude oil is introduced into the slag removal box through the feed hopper. First, the crude oil is filtered and slag removed by multiple sets of screening components and knocking components. Then, the screening barrel is driven to rotate by the rotation power component to filter and remove slag from the crude oil. Finally, the oil is discharged through the discharge pipe. Through multiple screenings, the oil slag removal is more thorough, and the quality of the oil output is improved.

[0004] The above technical solution also mentions that when it is necessary to disassemble the screening components and screening barrel and clean the internal debris, simply open the sealed box door, the screening components slide out from the concave groove through the sliding plate, and remove the bolts on the sleeve to take out the screening barrel.

[0005] However, the screen plates in the screening assembly trap and filter the gravel particles, which then accumulate on the top of the screen plates. As the slag removal process continues, more and more gravel particles will remain on the screen plates, thus reducing the slag removal efficiency of the screen plates. Simply removing the screen plates to clean the gravel particles later is not timely enough, further reducing the overall slag removal efficiency. Utility Model Content

[0006] In view of the above problems, this utility model provides a slag removal device for oil exploration and development, the purpose of which is to prevent the accumulation of gravel particles and improve the filtration effect.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A slag removal device for oil exploration and development is provided, comprising: a housing, hollow inside; a slag removal cylinder, cylindrical in shape, disposed within the housing; an oil inlet pipe, disposed at the upper end of the housing, for inputting crude oil into the slag removal cylinder; an oil outlet pipe, disposed at the lower end of the housing, for outputting oil; a slag removal plate, disposed at the bottom of the slag removal cylinder; a plurality of filter holes, formed on the slag removal plate; a rotating shaft, coaxially mounted with the slag removal cylinder, rotatably disposed within the housing; a plurality of scrapers, arranged in a circumferential array on the rotating shaft, one side of the scrapers extending towards the inner wall of the slag removal cylinder; a slag outlet, located on the side away from the oil inlet pipe, formed radially on the slag removal plate; a slag receiving component, disposed below the slag outlet; and a drive assembly for driving the rotating shaft to rotate.

[0008] Furthermore, four scrapers are arranged in a circumferential array at 90° intervals on the rotating shaft.

[0009] Furthermore, the device also includes a guide block, which is disposed between any two adjacent scrapers, with one side disposed on the rotating shaft and the other side extending obliquely toward the slag outlet.

[0010] Furthermore, one side of the scraper is fixedly mounted on the rotating shaft, and the other side of the scraper is provided with an arc surface.

[0011] Furthermore, the device also includes: a material inlet, which is opened on the side wall of the box; a support rod, which is fixedly installed on the inner wall of the box, with one end inside the material inlet and the other end extending into the box to support the slag receiving component; a mounting plate, which is installed on one side of the slag receiving component and located outside the box; and fixing screws, which can pass through the mounting plate and are installed on the side wall of the box through threaded connection.

[0012] Furthermore, the device also includes a sealing ring made of rubber, which is disposed between the mounting plate and the housing along the contour of the feed port.

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0018] Reference Figure 1 and Figure 2 As shown in the embodiment of this application, a slag removal device for oil exploration and development is disclosed, comprising: a housing 1, which is hollow inside; a slag removal cylinder 2, which is cylindrical and disposed inside the housing 1; an oil inlet pipe 11, which is disposed at the upper end of the housing 1 and is used to input crude oil into the slag removal cylinder; an oil outlet pipe 12, which is disposed at the lower end of the housing 1 and is used to output oil; a slag removal plate 3, which is disposed at the bottom of the slag removal cylinder 2; a plurality of filter holes, which are formed on the slag removal plate; a rotating shaft 4, which is coaxially mounted with the slag removal cylinder 2 and is rotatably disposed inside the housing 1; a plurality of scrapers 41, which are arranged in a circumferential array on the rotating shaft 4, with one side of the scrapers 41 extending toward the inner wall surface of the slag removal cylinder 2; a slag outlet 31, which is located on the side away from the oil inlet pipe 11 and is formed radially on the slag removal plate 3; a slag receiving component 6, which is disposed below the slag outlet 31; and a drive assembly, which is used to drive the rotating shaft 4 to rotate.

[0019] Specifically, the slag removal cylinder 2 is vertically installed inside the housing 1. One end of the oil inlet pipe 11 is installed vertically towards the filter plate 3. Crude oil mixed with gravel particles is input into the slag removal cylinder 2 through the oil inlet pipe 11. Under the action of gravity, the oil flows downward through the filter holes and is transported outward through the oil outlet pipe 12. The gravel particles are intercepted above the filter plate 3. The drive component is started, and the rotating shaft 4 rotates, driving the scraper 41 to rotate inside the slag removal cylinder 2. The moving scraper 41 scrapes the gravel particles above the filter plate 3 until the gravel particles fall from the slag outlet 31 into the slag receiving component 6.

[0020] By using this invention, the gravel particles intercepted above the filter plate 3 can be self-cleaned, preventing the gravel particles from accumulating on the filter plate 3 for a long time, and effectively ensuring the filtration effect of the filter plate 3.

[0021] It is worth mentioning that the bottom of the box 1 is equipped with support legs by welding, and the support legs can be fixed to the ground by bolts; support rods are also welded and installed on the outer wall of the slag removal cylinder 2, and the support rods are installed on the inner wall of the box 1 by screws.

[0022] It is understandable that a throttle valve can be added to the oil inlet pipe 11 to control the flow rate of the input crude oil and prevent the crude oil from overflowing directly into the slag removal cylinder 2 due to excessive input rate.

[0023] Preferably, four scrapers 41 are arranged in a circumferential array at 90° intervals on the rotating shaft 4.

[0024] In this embodiment, by setting four scrapers 41 to divide the upper side of the filter plate 3 into four equal parts, the lower part of the slag outlet 31 and the oil inlet pipe 11 are isolated, preventing crude oil mixed with gravel particles from falling directly from the oil inlet pipe 11 into the slag outlet 31, thus ensuring the normal filtering function of the filter plate 3.

[0025] Preferably, the height of the scraper 41 is less than the height of the slag removal cylinder 2.

[0026] Specifically, the device also includes: a guide block 42, which is disposed between any two adjacent scrapers 41, with one side disposed on the rotating shaft 4 and the other side extending obliquely toward the slag outlet 31; the guide block 42 is in the shape of a quarter cone. By setting the guide block 42, it is possible to prevent the stone particles from accumulating between the right angle corner formed by the rotating shaft 4 and the filter plate 3, and to ensure the smooth discharge of the stone particles.

[0027] It is understandable that filter holes are also provided around the slag receiving component 6 to allow oil to drip out.

[0028] Specifically, one side of the scraper 41 is fixedly installed on the rotating shaft 4, and the other side of the scraper 41 is provided with an arc surface to reduce wear between the scraper 41 and the slag receiving component 6.

[0029] Preferably, the device further includes: a material inlet, which is opened on the side wall of the box 1; a support rod 51, which is fixedly installed on the inner wall of the box 1, with one end inside the material inlet and the other end extending toward the inside of the box 1, for supporting the slag receiving component 6; a mounting plate 52, which is installed on one side of the slag receiving component 6 and located outside the box 1; and a fixing screw 53, which can pass through the mounting plate 52 and is installed on the side wall of the box 1 by threaded connection.

[0030] The device also includes a sealing ring made of rubber, which is disposed between the mounting plate 52 and the housing 1 along the contour of the feed port.

[0031] When it is necessary to clean the gravel particles inside the slag receiving component 6, the staff should manually remove the fixing screws 53, then pull the handle on the mounting plate 52 to remove the slag receiving component 6. After cleaning the gravel particles, the slag receiving component 6 can be reinstalled.

[0032] In this embodiment, the drive assembly includes a servo motor 7 and a gear. The output shaft of the servo battery is connected to the rotating shaft 4 via gear transmission. One end of the rotating shaft 4 is rotatably mounted inside the housing 1 via a bearing seat. The bearing seat is mounted on the inner wall of the housing 1 via a support rod. The other end of the rotating shaft 4 passes through the housing 1 and is connected to the output shaft of the servo motor 7 via gear transmission.

[0033] It is understood that those skilled in the art can use existing programmable logic controllers and PLC programming languages ​​to control the start and stop of the servo motor 7. The output shaft of the servo motor 7 can perform periodic start and stop movements or uniform movements.

[0034] It is worth mentioning that a rotary seal should be applied between the rotating shaft 4 and the housing 1, which can be an existing mechanical seal or a packing seal.

[0035] Those skilled in the art will understand that although preferred embodiments of the present invention have been described, those skilled in the art, once they learn the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
