Description

Technical Field

[0001] The invention relates to the technical field of filtration, and in particular to a polymer low-shear filtration device. Background Art

[0002] In the tertiary oil recovery method for improving oil recovery rate, low shear polymers are used as oil displacement agents, but there is still uneven mixing of some low shear polymers in the preparation process. In order to ensure the quality of the low shear polymer, a filtering device is required to filter the low shear polymer before use. During the use of the existing filtering device, in order to ensure the stability of the filter element inside the device during use, the filter element is usually fixed inside the filtering device. Although this is stable enough, when the filter element reaches the load and needs to be replaced, the staff needs to perform trivial steps to disassemble the filter element and reinstall it, which reduces the replacement efficiency of the filter element. For this reason, the present invention improves a filtering device that is easy to replace the filter element. Summary of the invention

[0003] The disclosed embodiment relates to a polymer low-shear filter device, which enables the positioning slide post to slide inwardly along the tension slide groove so that the positioning slide post clamps and positions the filter cartridge from four directions, thereby ensuring the stability of the filter cartridge during use. When the filter cartridge needs to be disassembled, it is only necessary to pull down the sliding support sleeve so that the sliding support sleeve moves downward with the positioning tray and the filter cartridge. After moving downward, the positioning slide post will slide outward along the tension slide groove so that the positioning slide post cancels the clamping position of the filter cartridge, thereby facilitating the disassembly and replacement of the filter cartridge. In this way, when the filter cartridge needs to be disassembled, the filtering device only needs to pull down the positioning tray so that the positioning tray slides out of the filter chamber with the filter cartridge. In the sliding process, the positioning slide post will also automatically cancel the clamping position of the filter cartridge with the cooperation of multiple structures, thereby facilitating the direct removal and replacement of the filter cartridge that has slipped out.

[0004] In the first aspect of the present disclosure, a polymer low-shear filtration device is provided, which specifically includes: a polymer filtration cavity and a discharge butt tube, wherein a trigger conversion bump of a hemispherical structure is fixedly installed on the inner rear side of the polymer filtration cavity; a feeding connecting tube is fixedly installed on the top of the polymer filtration cavity; the top of the feeding connecting tube is connected to the feed pipe; the bottom end of the discharge butt tube is connected to the discharge pipe; a support guide plate is fixedly installed on the top of the discharge butt tube; support guide columns of a cylindrical structure are fixedly installed on the left and right sides of the top of the support guide plate; a sliding support sleeve is slidably installed on the support guide column; one end of a vertical spring is embedded in the bottom of the sliding support sleeve; the other end of the vertical spring is embedded in the top of the support guide plate; one end of a telescopic stretching tube is inserted and fixed in the center of the top of the discharge butt tube; a positioning tray is fixedly installed in the center of the top of the sliding support sleeve.

[0005] In at least some embodiments, the other end of the telescopic stretch tube is inserted and fixed at the bottom end of the positioning tray; the top of the positioning tray is provided with tensioning guide slots arranged in a cross shape; a cylindrical positioning tensioning slide column is slidably installed inside the tensioning guide slot; one end of a transverse spring is embedded and installed on the outer side of the positioning tensioning slide column; the other end of the transverse spring is embedded and installed on the outer side wall of the tensioning guide slot; a diversion connecting tube is fixedly installed at the center of the top of the positioning tray.

[0006] In at least some embodiments, the bottom end of the diversion connecting tube is also connected to the top end of the telescopic stretch tube; a limiting support plate with a disc-shaped structure is fixedly installed on the circumferential outer wall of the diversion connecting tube; a trigger pulling turntable with a disc-shaped structure is also rotatably installed on the diversion connecting tube; the top of the trigger pulling turntable is provided with trigger pulling grooves arranged in a cross shape; the trigger pulling groove is an arc structure; the top end of the positioning elastic sliding column is also slidably installed inside the trigger pulling groove.

[0007] In at least some embodiments, a driven conversion plate with an arc-shaped structure is fixedly installed on one side of the top of the trigger pull turntable; a driven conversion bevel groove with an inclined structure is opened at the outer bottom of the driven conversion plate; a driven retaining vertical groove is opened at the outer top of the driven conversion plate; the bottom end of the driven retaining vertical groove is connected to the top of the driven conversion bevel groove; the trigger conversion protrusion is also slidably installed in the driven groove composed of the driven retaining vertical groove and the driven conversion bevel groove; and a polymer filter cartridge is inserted at the top of the diversion connecting tube.

[0008] In at least some embodiments, the bottom of the polymer filter cartridge also rests on the limiting support plate; a polymer collecting funnel with an inverted cone structure is fixedly installed on the top of the polymer filter cartridge; the polymer collecting funnel is also slidably installed inside the polymer filter cavity; a polymer filter element is fixedly arranged inside the polymer filter cartridge; when the positioning tray and the sliding support sleeve move downward along the support guide column, the trigger conversion protrusion will utilize the inclined structure of the driven conversion inclined groove to drive the driven conversion plate and the trigger pull turntable to rotate; when the trigger pull turntable rotates, the trigger pull turntable will utilize four arc-shaped trigger pulling grooves to cooperate with the transverse spring to drive the positioning tension sliding column to slide along the tension guide sliding groove.

[0009] The present invention provides a polymer low shear filtration device, which has the following beneficial effects:

[0010] The filter device clamps and positions the filter cartridge in the filtering state from four directions through the positioning slide post, so that the filter cartridge can ensure its own stability during filtration. When the filter cartridge needs to be removed, the filter device only needs to pull down the positioning tray to slide the positioning tray with the filter cartridge out of the filter cavity. During the sliding process, the positioning slide post will automatically cancel the clamping position of the filter cartridge with the cooperation of multiple structures, so that the filter cartridge that has slid out can be directly taken out and replaced.

[0011] The filter device can ensure the stability of the filter cartridge during use by positioning the slide column, and the steps of replacing the filter cartridge will not be too complicated due to the clamping and positioning of the filter cartridge, and the replacement of the filter cartridge will not consume too much time, so that the filter device ensures stability during use and easy operation.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention.

Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Please refer to Figures 1 to 8 :

[0028] Embodiment 1: The present invention proposes a polymer low-shear filtration device, comprising a polymer filtration cavity 1 and a discharge butt tube 4, wherein a trigger conversion protrusion 2 with a hemispherical structure is fixedly installed on the inner rear side of the polymer filtration cavity 1; a feeding connecting tube 3 is fixedly installed on the top of the polymer filtration cavity 1; the top of the feeding connecting tube 3 is connected to the feed pipe; the bottom end of the discharge butt tube 4 is connected to the discharge pipe; a support guide plate 5 is fixedly installed on the top of the discharge butt tube 4; cylindrical support guide columns 6 are fixedly installed on the left and right sides of the top of the support guide plate 5; a sliding support sleeve plate 7 is slidably installed on the support guide column 6; one end of a vertical spring 8 is embedded in the bottom of the sliding support sleeve plate 7; the other end of the vertical spring 8 is embedded in the top of the support guide plate 5; one end of a telescopic stretching tube 9 is inserted and fixed at the center position of the top of the discharge butt tube 4; a positioning tray 10 is fixedly installed at the center position of the top of the sliding support sleeve plate 7.

[0029] By connecting the loading connecting tube 3 to the external low-shear polymer loading pipeline, and connecting the unloading butt joint tube 4 to the external low-shear polymer unloading pipeline, after the low-shear polymer enters the polymer filtration cavity 1 through the loading connecting tube 3, the low-shear polymer will enter the polymer filter cylinder 21 through the polymer collecting funnel 22, so that the polymer filter element 23 inside the polymer filter cylinder 21 filters the low-shear polymer, and the treated low-shear polymer will enter the unloading pipeline through the diversion connecting tube 14, the telescopic stretching tube 9 and the unloading butt joint tube 4 in turn, so that the unloading pipeline can guide the filtered low-shear polymer to a suitable position.

[0030] Embodiment 2, on the basis of embodiment 1, the other end of the telescopic stretching tube 9 is inserted and fixed at the bottom end of the positioning tray 10; the top of the positioning tray 10 is provided with a tension guide slot 11 arranged in a cross shape; a cylindrical positioning tension slide post 12 is slidably installed inside the tension guide slot 11; one end of a transverse spring 13 is embedded and installed on the outer side of the positioning tension slide post 12; the other end of the transverse spring 13 is embedded and installed on the outer side wall of the tension guide slot 11; the top of the positioning tray 10 is fixed in the center A diversion connecting tube 14 is fixedly installed; the bottom end of the diversion connecting tube 14 is also connected to the top of the telescopic stretching tube 9; a disc-shaped limit support plate 15 is fixedly installed on the circumferential outer wall of the diversion connecting tube 14; a trigger pulling turntable 16 with a disc-shaped structure is also rotatably installed on the diversion connecting tube 14; the top of the trigger pulling turntable 16 is arranged in a cross shape and has a trigger pulling groove 17; the trigger pulling groove 17 is an arc structure; the top of the positioning elastic sliding column 12 is also slidably installed inside the trigger pulling groove 17.

[0031] After the polymer filter element 23 reaches the use load, the sliding support sleeve 7 and the positioning tray 10 are manually pulled downward, so that the positioning tray 10 moves downward along the support guide column 6 with the polymer filter cartridge 21. In summary of the movement process, the trigger conversion protrusion 2 will preferentially use the inclined structure of the driven conversion inclined groove 19 to rotate the driven conversion plate 18, the trigger pulling turntable 16 and the trigger pulling groove 17, so that the trigger pulling groove 17 uses its own arc structure to slide the positioning tension slide column 12 outward along the tension guide slide groove 11, so that the positioning tension slide column 12 cancels the clamping positioning of the polymer filter cartridge 21 to be replaced by moving outward, and then after the positioning tray 10 slides down with the polymer filter cartridge 21 and detaches from the interior of the polymer filter cavity 1, the polymer filter cartridge 21 inserted on the diversion connecting tube 14 can be directly removed and replaced, which is more convenient to replace.

[0032] Embodiment 3, on the basis of embodiment 2, a driven conversion plate 18 with an arc structure is fixedly installed on one side of the top of the trigger pull turntable 16; a driven conversion chute 19 with an inclined structure is provided at the outer bottom of the driven conversion plate 18; a driven retaining vertical groove 20 is provided at the outer top of the driven conversion plate 18; the bottom end of the driven retaining vertical groove 20 is connected to the top end of the driven conversion chute 19; the trigger conversion protrusion 2 is also slidably installed in the driven groove composed of the driven retaining vertical groove 20 and the driven conversion chute 19; a polymer filter cartridge 21 is inserted at the top of the diversion connecting tube 14; the bottom of the polymer filter cartridge 21 also rests on the limit support plate 15; the polymer filter cartridge 21 A polymer collecting funnel 22 with an inverted cone structure is fixedly installed on the top; the polymer collecting funnel 22 is also slidably installed inside the polymer filter cavity 1; a polymer filter element 23 is fixedly arranged inside the polymer filter cartridge 21; when the positioning tray 10 and the sliding support sleeve 7 move downward along the support guide column 6, the trigger conversion protrusion 2 will utilize the inclined structure of the driven conversion inclined groove 19 to drive the driven conversion plate 18 and the trigger pull turntable 16 to rotate; when the trigger pull turntable 16 rotates, the trigger pull turntable 16 will utilize the four arc-shaped trigger pulling grooves 17 to cooperate with the transverse spring 13 to drive the positioning tension slide column 12 to slide along the tension guide slide groove 11.

[0033] After removing the loaded polymer filter cartridge 21, a new polymer filter cartridge 21 is inserted into the top of the flow guide connecting tube 14 for a second time so that the new polymer filter cartridge 21 is located between the four positioning tension slide columns 12. Then, by releasing the downward pull on the positioning tray 10 and the sliding support sleeve 7, the positioning tray 10 is lifted up with the new polymer filter cartridge 21 into the interior of the polymer filter cavity 1. During the rising process, the trigger pull turntable 16 will restore with the trigger pull groove 17. At the same time, the four positioning tension slide columns 12 will also restore under the action of the transverse spring 13, so that the four positioning tension slide columns 12 clamp and position the polymer filter cartridge 21 from four directions, thereby ensuring the stability of the new polymer filter cartridge 21 after it is put into use.

[0034] Working principle:

[0035] First, the feeding connection pipe 3 is connected to the external low-shear polymer feeding pipe, and the unloading connection pipe 4 is connected to the external low-shear polymer unloading pipe, so that after the low-shear polymer enters the interior of the polymer filtration cavity 1 through the feeding connection pipe 3, the low-shear polymer will enter the interior of the polymer filter cartridge 21 through the polymer collecting funnel 22, so that the polymer filter core 23 in the polymer filter cartridge 21 filters the low-shear polymer, and the treated low-shear polymer will pass through the guide connecting pipe 14, the telescopic stretching pipe 9 and the unloading connection pipe in turn. The pipe 4 enters the discharge pipe, which is convenient for the discharge pipe to guide the filtered low-shear polymer to a suitable position. After the polymer filter element 23 reaches the use load, the sliding support sleeve 7 and the positioning tray 10 are manually pulled downward, so that the positioning tray 10 moves downward with the polymer filter cartridge 21 along the support guide column 6. In summary of the movement process, the trigger conversion protrusion 2 will preferentially use the inclined structure of the driven conversion chute 19 to drive the driven conversion plate 18, the trigger pull turntable 16 and the trigger pull groove 17 to rotate, so that the trigger pull groove 17 uses its own arc structure to drive the driven conversion plate 18, the trigger pull turntable 16 and the trigger pull groove 17 to rotate. The positioning elastic slide post 12 slides outward along the elastic guide slide groove 11, so that the positioning elastic slide post 12 cancels the clamping positioning of the polymer filter cartridge 21 to be replaced by moving outward, and then after the positioning tray 10 slides down with the polymer filter cartridge 21 and leaves the interior of the polymer filter cavity 1, the polymer filter cartridge 21 inserted on the flow guide connecting tube 14 can be directly removed for replacement, which is more convenient. After the loaded polymer filter cartridge 21 is removed, a new polymer filter cartridge 21 is inserted into the top of the flow guide connecting tube 14 for the second time, so that the new polymer filter cartridge 21 is replaced. The filter cartridge 21 is located between the four positioning elastic slide columns 12, and then the positioning tray 10 and the sliding support sleeve 7 are released to make the positioning tray 10 rise with the new polymer filter cartridge 21 into the interior of the polymer filter chamber 1. During the rising process, the trigger pull turntable 16 will restore with the trigger pull groove 17, and at the same time, the four positioning elastic slide columns 12 will also restore under the action of the transverse spring 13, so that the four positioning elastic slide columns 12 clamp and position the polymer filter cartridge 21 from four directions, ensuring the stability of the new polymer filter cartridge 21 after it is put into use.
