Description

Technical Field

[0001] The utility model belongs to the field of polymer mixing in petroleum exploitation, in particular to a split type polymer mixer. Background Art

[0002] At present, polymer flooding is mainly used in tertiary oil recovery in oil fields, which can improve the recovery rate by reducing the water-oil mobility ratio. The static mixer used on site is welded as an integral structure. After long-term use, the internal swirl plate and mixing pipeline of the mixer are seriously scaled, which affects the subsequent use; and because the components of the existing mixer are integrally formed or cannot be disassembled, the inside of the mixer cannot be cleaned. The only way to avoid the influence of internal swirl plate scaling on mixing is to replace the entire mixer, which causes the defect of high use cost of the existing mixer.

[0003] In summary, the existing mixer structure is integrally formed, and there is a problem that it is difficult to clean the scale of the mixer. Utility Model Content

[0004] The utility model aims to provide a split polymer mixer to solve the technical problem that the mixer structure in the prior art is integrally formed and it is difficult to clean the scale of the mixer.

[0005] In order to achieve the above-mentioned purpose, the technical solution of a split polymer mixer provided by the utility model is:

[0006] A split polymer mixer comprises a mixing pipeline and a split swirl plate, both ends of the mixing pipeline are provided with flanges, one end of the swirl plate is provided with a connector, the connector is provided with a channel for fluid to pass through, and the connector is also provided with a fixing structure for fixing and assembling with the flange at one end of the mixing pipeline.

[0007] The beneficial effect is that the swirl plate and the mixing pipe are two separate components, wherein flanges are provided at both ends of the mixing pipe, a flange connector is provided at one end of the swirl plate, and the connector is connected to a flange of the mixing pipe, further realizing the effect of connecting and assembling the swirl plate and the mixing pipe, and the connector is provided with a channel for fluid to flow through. The split swirl plate and the mixing pipe can be disassembled and cleaned separately, ensuring that the inside of the mixer can be kept clean. Compared with the prior art, the mixer is easy to clean, further reducing the use cost of the mixer, and can also reduce the labor intensity of employees and improve work efficiency.

[0008] As a further improvement, the connector adopts an inner hole structure, on which a fixing plate is arranged, and the space between the fixing plate and the inner hole forms a channel.

[0009] The beneficial effect is that the swirl plate can be connected to the fixing plate to realize the effect of connecting the swirl plate to the connecting head.

[0010] As a further improvement, the end surface of the fixing plate facing the axial side of the swirl plate is used to form a fixing surface for welding the swirl plate.

[0011] The beneficial effect is that by welding the fixed plate to the swirl plate, the connection between the swirl plate and the fixed plate is more stable and easier to process than the connection between the swirl plate and the connecting head without the fixed plate; at the same time, when there is no fixed plate, the width of the swirl plate needs to be greater than the diameter of the inner hole of the connecting head in order to be connected to the connecting head. With the fixed plate, the effect of connecting to the connecting head can be achieved when the outer diameter of the swirl plate is smaller than the inner hole diameter, which makes it convenient for the swirl plate to reduce the inner diameter as needed.

[0012] As a further improvement, the fixing surface is flush with the end surface of the connecting head facing the swirl plate.

[0013] The beneficial effect is that the fixing surface and the welding surface of the swirl plate are ensured to be neither too long to waste materials nor too short to cause incomplete welding.

[0014] As a further improvement, the fixing structure is a threaded connection, and the end surface of the fixing plate facing away from the axial side of the swirl plate is used to form a rotation-stopping end surface that cooperates with the disassembly and assembly tool.

[0015] The beneficial effects are: the threaded connection is easier to disassemble and assemble, and the anti-rotation end surface makes it easier to rotate the connector using a disassembly tool, thereby realizing the function of conveniently disassembling the connector and the components fixedly connected to the connector.

[0016] As a further improvement, the fixing structure is a threaded connection, the connecting head is provided with an external thread, and the flange fixedly assembled with the connecting head is provided with an internal thread that cooperates with the external thread.

[0017] The beneficial effect is that the flange is connected to the connector through threads, and the connection between the connector and the flange can be achieved through simple operations of screwing in and out.

[0018] As a further improvement, a step surface for limiting the connection depth of the connecting head is provided on the inner circumferential surface of the flange fixedly assembled with the connecting head.

[0019] The beneficial effect is that when the connector and the flange are threaded connection structures, the depth of the connector screwed into the flange cannot be visually observed. When the connector has entered the standard depth, the staff may not observe it and continue to screw the connector in, which will cause wear of the thread or even stripping. Therefore, the step surface is used to limit the depth of the connector entering the flange to reduce the wear of the internal and external threads and avoid excessive screwing to damage the threads.

[0020] As a further improvement, the end surface of the connecting head facing away from the axial side of the swirl plate is flush with or lower than the outer end surface of the flange fixedly assembled with the connecting head.

[0021] The beneficial effect is that the flange is easy to connect with other devices.

[0022] As a further improvement, the end surface of the fixing plate facing away from the axial side of the swirl plate is flush with or lower than the outer end surface of the flange fixedly assembled with the connecting head.

[0023] The beneficial effect is: preventing the fixing plate from exceeding the outer end surface of the flange, and facilitating the connection of the flange with other devices.

[0024] As a further improvement, the inner diameter of the mixing pipe is the same as the outer diameter of the swirl plate.

[0025] The beneficial effect is that the mixer can mix the compound more evenly. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0040] Split polymer mixer embodiment:

[0041] like Figure 1-Figure 10 As shown, the split polymer mixer includes a swirl plate 3 and a mixing pipe 4 which are separately arranged. Both ends of the mixing pipe 4 are provided with flanges, namely, a first flange 1 and a second flange 2. One end of the swirl plate 3 is provided with a connector 5 for connecting with the first flange 1. The connector 5 is provided with a channel for fluid to pass through. The connector 5 is also provided with a fixing structure for fixing and assembling with the first flange at one end of the mixing pipe 4. The second flange 2 of the mixing pipe 4 is used to be connected to the wellhead. The fixing structure can be any connection structure that is easy to disassemble and assemble, such as a threaded connection structure or a clamping structure. If a threaded structure is adopted, the first flange 1 adopts an internal threaded flange, and the connector 5 adopts an external threaded connector. If a clamping structure is adopted, a groove is provided on the inner circumference of the first flange 1, and a protrusion is provided on the outer circumference of the connector 5 to match the groove. This embodiment adopts a threaded connection that is easy to make and has a simpler connection operation.

[0042] The connector 5 has an inner hole structure, on which a fixing plate 6 is arranged, and the space between the fixing plate 6 and the inner hole forms a channel. The channel is used for the mixed solution to flow in and out. The fixing plate 6 can be any plate shape that can cooperate with the disassembly and assembly tool, such as a straight plate or a cross plate.

[0043] The end surface of the fixed plate 6 facing the axial side of the swirl plate 3 is used to constitute the fixed surface for welding the swirl plate 3. Compared with the swirl plate being directly welded to the bottom surface of the connecting head 5, the welding process of the fixed plate 6 and the swirl plate 3 is simpler. Because when there is no fixed plate 6, the connecting head 5 is connected to the two ends of the connecting end surface of the swirl plate 3, and the middle part of the connecting end surface of the swirl plate 3 corresponds to the position of the inner hole of the connecting head 5, and welding cannot be performed. In this way, the welding process is not only complicated, but also unstable. When there is a fixed plate 6, the fixed surface used for welding with the swirl plate 3 is a long narrow surface, and the swirl plate 3 itself is also a long narrow surface used for welding. Two surfaces of similar shapes are welded together, which not only simplifies the welding process, but also makes the welding stable.

[0044] In addition, the fixing surface is flush with the end surface of the connecting head 5 facing the swirl plate 3 . This design is also for facilitating welding of the fixing plate 6 and the swirl plate 3 .

[0045] When the fixing structure is a threaded connection, the end surface of the fixing plate 6 facing away from the axial side of the swirl plate 3 is used to form a rotation-stopping end surface that cooperates with the disassembly tool. The disassembly tool cooperates with the rotation-stopping end surface of the fixing plate 6, and the effect of disassembling the swirl plate 3 is achieved by rotating the fixing plate 6. In addition, when the fixing structure is a threaded connection, the structure of the fixing plate 6 may not be used. For example, the inner hole of the connector may adopt a polygonal structure, and the effect of convenient disassembly of the connector may be achieved by using a polygonal disassembly tool.

[0046] Threaded connections are prone to over-screwing, resulting in thread wear or stripping. In order to avoid this phenomenon, a step surface 11 is provided on the inner circumference of the first flange 1 to limit the connection height of the connector 5; the step surface 11 is used to limit the depth of the connector 5 screwed into the first flange 1.

[0047] Since when the connector 5 or the fixing plate 6 exceeds the outer end face of the first flange 1, the device connected to the first flange 1 needs to be provided with a structure for placing the protruding part of the connector 5 or the fixing plate 6, which results in that the connection object of the first flange 1 must meet certain conditions before it can be connected, increasing the difficulty of connecting the first flange 1 with other devices. Therefore, in order to facilitate the first flange 1 to be easily connected with other devices, the end face of the connector 5 on the axial side facing away from the swirl plate 3 is flush with or lower than the outer end face of the first flange 1, and the end face of the fixing plate 6 on the axial side facing away from the swirl plate 3 is flush with or lower than the outer end face of the first flange 1.

[0048] In order to make the mixer mix the compound uniformly, the inner diameter of the mixing pipe 4 is the same as the outer diameter of the swirl plate 3, and the swirl level of the swirl plate 3 is 6 to 15. The higher the level of the swirl plate 3, the more uniform the mixing.

[0049] Specific principle: the prepared solution flows from the first flange 1 into the mixing pipe 4, flows through the swirl plate 3 for uniform and sufficient mixing, and then flows out from the third connection part of the mixing pipe 4 and flows into the designated wellhead. When the present application is in use, it can solve the problem that the swirl plate 3 and the mixing pipe 4 cannot be cleaned after scaling, and the disassembled swirl plate 3 and the mixing pipe 4 are cleaned through the split structure. When scaling occurs in the split mixer, the swirl plate 3 is disassembled after the split mixer is removed, and the scaling operation is performed on the first flange 1, the second flange 2, the inside of the mixing pipe 4 and the swirl plate 3 respectively. Then use a special disassembly wrench to install the swirl plate 3 on the first flange 1, and then install the device as a whole on the injection polymerization process.

[0050] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
