[0002] In the field of oil extraction technology, in order to improve oil recovery rate, it is often necessary to use a liquid preparation device to disperse and prepare pre-crosslinked particles and solutions. Existing liquid preparation devices, such as the pre-crosslinked gel particle production system disclosed in utility model patent CN215028715U, can meet the requirements to a certain extent, but they have the following problems:

[0003] First: The existing production system directly controls the feeding of pre-crosslinked particles by switching valves. This has problems such as moisture rising during feeding, rapid gel formation, pipe blockage, and difficulty in continuous and accurate feeding.

[0004] Second: When the existing production system is in operation, after the pre-crosslinked particles enter the dispersion tank, the pre-crosslinked particles are very likely to form dust in the dispersion tank and eventually stick to the inner wall of the dispersion tank, forming clumps and fish eyes in the fluid inside the tank, which seriously affects the uniform dispersion and full emulsification of the pre-crosslinked particles.

[0005] Therefore, it is necessary to develop a new liquid preparation device to solve the above-mentioned problems of existing liquid preparation devices. Summary of the Invention

[0027] This pre-crosslinked particle dispersion and dispensing device includes two dispersion tanks 1, a feeder 5, a spray nozzle 4, a stirring shaft 8, stirring blades 9, an annular liquid guide pipe 3, and an adjustable fan-shaped nozzle 6 (see the attached instruction manual). Figure 1 and 2 ).

[0028] Two sets of dispersion tanks 1 are symmetrically arranged; each dispersion tank 1 is equipped with a sealing cover 2; a stirring shaft 8 is mounted on the sealing cover 2 via a drive motor 7; the stirring shaft 8 extends into the dispersion tank 1 and is fitted with stirring blades 9 (see the instruction manual appendix). Figure 5 and 6 When the drive motor 7 is working, it can drive the stirring blade 9 to rotate through the stirring shaft 8; during the rotation of the stirring blade 9, the pre-crosslinked particles can be fully stirred and mixed with the prepared solution.

[0029] The sealing cap 2 is equipped with an annular liquid guide tube 3 and a spray nozzle 4 (see instruction manual appendix). Figure 6 and 7 ).

[0030] The annular liquid guide tube 3 is connected to an external liquid supply system through a liquid guide port. During operation, the external liquid supply system can input the prepared liquid with a certain pressure into the annular liquid guide tube 3.

[0031] The lower part of the annular liquid guide tube 3 extends into the interior of the dispersion tank 1 and is uniformly fitted with multiple adjustable fan-shaped nozzles 6 (see the instruction manual appendix). Figure 5 and 6 During operation, the prepared liquid enters the annular liquid guide pipe 3 and is sprayed out in a fan shape through the adjustable fan-shaped nozzles 6. The purpose of this setting is to ensure that after the adjustable fan-shaped nozzles 6 spray the prepared liquid in a fan shape, the spraying range of adjacent adjustable fan-shaped nozzles 6 will partially overlap and spray downward onto the inner wall of the dispersion tank 1. In this way, a liquid film is formed on the inner wall of the dispersion tank 1, thereby achieving the problem of isolating pre-crosslinked particles through the liquid film and preventing them from adhering to the inner wall of the dispersion tank 1 and causing scaling.

[0032] The feeder 5 is connected to the spray nozzles 4 on the two sets of dispersion tanks 1 respectively; the spray nozzle 4 includes an outer sleeve 10, an inner sleeve 12, a connecting flange 13 and a dispersion plate 15 (see the instruction manual appendix). Figure 8 and 9 ).

[0033] An outer sleeve 10 is fitted onto the sealing cap 2; an inner sleeve 12 is fixed inside the outer sleeve 10 via a sealing ring 11; a connecting flange 13 is fitted at the upper end of the inner sleeve 12 extending to the upper part of the outer sleeve 10; the spray nozzle 4 is connected to the feeder 5 via the connecting flange 13; a wedge-shaped outlet 14 is provided at the lower end of the inner sleeve 12 extending to the lower part of the outer sleeve 10; a dispersing plate 15 is installed at the lower end of the wedge-shaped outlet 14 in an inclined manner. A certain gap exists between the dispersing plate 15 and the wedge-shaped outlet 14 (see the instruction manual appendix). Figure 9 ).

[0034] The outer sleeve 10 is provided with a connecting nozzle 16; the connecting nozzle 16 is connected to the annular space between the outer sleeve 10 and the inner sleeve 12 (see the instruction manual appendix). Figure 9 ).

[0035] The purpose of this spray nozzle 4 design is to ensure that, during operation, the pre-crosslinked particles, guided by the inner sleeve 12 and the dispersing plate 15, are dispersed and fall into the dispersion tank 1 to mix with the prepared liquid. This avoids the problem of pre-crosslinked particles concentrating in the dispersion tank 1, resulting in poor dispersion. During this process, the external air pressure system can inject compressed air into the annulus between the outer sleeve 10 and the inner sleeve 12 through the connecting nozzle 16. As the compressed air moves downwards along the annulus, it compresses the pre-crosslinked particles, preventing them from adhering to the bottom of the sealing cap 2 during their upward movement.

[0036] The feeder 5 includes an auger cylinder 17, an auger shaft 20, a storage hopper 18, spiral blades A21 and B22, and a guide cylinder 23; the upper middle part of the auger cylinder 17 is connected to the storage hopper 18 (see the attached instruction manual). Figure 3 and 4 ).

[0037] The auger cylinder 17 is equipped with an auger shaft 20 via a feeding motor 19; spiral blades A21 and B22 are symmetrically mounted on the auger shaft 20 on both sides below the storage hopper 18; guide cylinders 23 are installed on the auger cylinder 17 below the spiral blades A21 and B22; the feeder 5 is connected to the corresponding connecting flange 13 on the spray nozzle 4 via the guide cylinder 23.

[0038] During the forward rotation of the auger shaft 20 driven by the feeding motor 19, the spiral blades A21 can transport the pre-crosslinked particles in the storage hopper 18 to the dispersion tank 1 on the left. During the reverse rotation of the auger shaft 20, the spiral blades B22 can transport the pre-crosslinked particles in the storage hopper 18 to the dispersion tank 1 on the left. During this process, since the interval between the spiral blades B22 is fixed, the feeding amount of the pre-crosslinked particles can be precisely controlled by controlling the number of rotations of the auger shaft 20.

[0039] An air inlet sleeve 24 is mounted on the auger cylinder 17 above the guide cylinder 23; an air jet pipe 25 is mounted on the air inlet sleeve 24; the air jet pipe 25 extends to the lower end of the corresponding inner sleeve 12 after passing around the auger shaft 20 (see the appendix of the instruction manual). Figure 3 , 5 and 10).

[0040] The purpose of setting up the jet pipe 25 is to enable the pre-crosslinked particles to fall into the dispersion tank 1 through the inner sleeve 12 during operation after the jet pipe 25 is connected to the external air supply system. The gas sprayed out by the jet pipe 25 can further disperse the pre-crosslinked particles so that they fall into the dispersion tank 1 more evenly.

[0041] In operation, the pre-crosslinked particle dispersion and dispensing device 5 uses a feeding motor 19 to drive the auger shaft 20 to rotate in either the forward or reverse direction, precisely conveying the pre-crosslinked particles in the storage hopper 18 to the corresponding dispersion tank 1; during this process, an external liquid supply system...

[0042] The prepared liquid is introduced into the annular liquid guide tube 3 under certain pressure. The prepared liquid entering the annular liquid guide tube 3 is sprayed out in a fan shape through the adjustable fan-shaped nozzle 6, and finally acts on the inner wall of the dispersion tank 1, so that a liquid film is formed on the inner wall of the dispersion tank 1.

[0043] After the preparation solution and pre-crosslinked particles enter the dispersion tank 1, the drive motor 7 drives the stirring blades 9 to rotate via the stirring shaft 8, thereby fully stirring the pre-crosslinked particles and fully mixing them with the preparation solution. This completes the pre-crosslinked particle dispersion and solution preparation process.

[0044] During the above process, as the pre-crosslinked particles fall through the inner sleeve 12, the gas ejected from the jet pipe 25, with the cooperation of the dispersing plate 15, further disperses the pre-crosslinked particles, causing them to fall evenly into the dispersion tank 1. At the same time, the external air pressure system can inject compressed air into the annulus between the outer sleeve 10 and the inner sleeve 12 through the connecting air nozzle 16. As the compressed air moves downward along the annulus, it can suppress the pre-crosslinked particles to move downward, thereby avoiding the problem of the pre-crosslinked particles adhering to the bottom of the sealing cap 2 during their upward movement.

[0045] This pre-crosslinked particle dispersion and preparation device has a compact structure and ingenious design. During operation, it solves the problems of difficult precise control of feeding and relatively poor product quality in existing pre-crosslinked gel particle production devices through the spraying and brushing action of the spray nozzle 4 and the feeding control of the feeder 5. It is particularly suitable for the needs of pre-crosslinked particle dispersion and preparation.
