Description

Technical Field

[0001] This utility model relates to the field of fracturing fluid preparation technology, and in particular to a synthesis reactor for oilfield fracturing fluid. Background Technology

[0002] Oilfield fracturing fluid is a mixture of main fluid and additives. It is a product used to assist fracturing operations and requires a synthesis reactor for its production.

[0003] The patent with announcement number CN221714318U discloses a synthesis reactor for oilfield fracturing fluid, which includes a reactor body, an inlet pipe fixedly installed on the upper surface of the reactor body, a stirring assembly movably installed inside the reactor body, a discharge pipe fixedly installed at the bottom of the reactor body, and a valve fixedly installed on the outer surface of the discharge pipe.

[0004] In the above case, the vibrating component strikes one side of the screening component, causing that side to rotate up and down repeatedly to screen the additives. However, since only one side moves up and down, the additives are not screened evenly. Furthermore, since the screening component rotates in a circular motion, the side that moves cannot always maintain a tight seal with the inner wall of the feed pipe, causing the additives above the filter screen to fall through the gaps, thus reducing the screening effect of the device.

[0005] Therefore, this invention provides a synthesis reactor for oilfield fracturing fluid to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to provide a synthesis reactor for oilfield fracturing fluid to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a synthesis reactor for oilfield fracturing fluid, comprising a reactor body for synthesizing oilfield fracturing fluid, wherein an addition pipe and a main fluid pipe are fixedly connected to both sides of the top of the reactor body, and a fixing seat is fixedly connected to the inner side of the addition pipe. The fixing seat includes elastic bars on both sides, and a filter screen is slidably connected to the inner side of the fixing seat. A compression ring is fixedly connected to the side of each of the two elastic bars away from each other. Several support rings are fixedly connected inside the compression rings. The filter screen is tightly fitted to the inner wall of the adding tube. An outer plate is fixedly connected to one end of the filter screen located outside the fixed base. Both ends of the outer plate have locking holes. A sliding rod is fixedly connected to the outer side of the adding tube directly above the outer plate. A moving plate is slidably connected to the outer side of the sliding rod. Both ends of the bottom of the moving plate are fixedly connected to locking rods. Each locking rod has two locking holes on its inner side. A rotating rod is rotatably connected to the inner side of the adding tube located below the fixed base. Both ends of the rotating rod are fixedly connected to striking blocks. A rotating shaft is rotatably connected to the top of the adding tube.

[0008] In a preferred embodiment, there are three support rings inside the same extrusion ring, and the support rings are elliptical.

[0009] In a preferred embodiment, the inside of the adding tube is provided with a mounting groove for sliding the outer plate, and the area of ​​the mounting groove is smaller than the side of the fixing seat near the outer plate.

[0010] In a preferred embodiment, a No. 1 motor is fixedly connected to the outside of the adding tube, one end of the rotating rod extends out of the adding tube and is fixedly connected to the output end of the No. 1 motor, and the two striking blocks are respectively located directly below the two spring bars.

[0011] In a preferred embodiment, a second motor is fixedly connected to the top of the vessel body, and its output end is fixedly connected to the top of the rotating shaft.

[0012] In a preferred embodiment, the rotating shaft is fixedly connected to a plurality of stirring blades on the outer side of the vessel body, and a base frame is fixedly connected to the bottom of the vessel body cavity, with the bottom of the rotating shaft rotatably connected to the inner side of the base frame.

[0013] In a preferred embodiment, a number of support legs are fixedly connected to the bottom of the outer side of the vessel body, a liquid outlet pipe is fixedly connected to the bottom of the vessel body, and a valve is fixedly connected to the outer side of the liquid outlet pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model, by setting a fixed seat, spring strips, a filter screen, and a striking block, allows the device to drive the striking block to rotate via a rotating rod, striking the spring strips on both sides, causing the elastic filter screen to vibrate up and down. The fixed seat limits the position of the filter screen, causing the middle of the filter screen to vibrate up and down, making the vibration screening of the filter screen more uniform and improving the screening efficiency.

[0016] This invention, by setting up a squeezing ring and a support ring, allows the support ring to push the squeezing ring tightly against the inner wall of the adding tube. This ensures that while the spring strip and the squeezing ring vibrate up and down, no gaps are formed between the squeezing ring and the adding tube, preventing the additives above the filter screen from falling down and improving the screening accuracy of the device.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0025] Please see Figures 1-5 This utility model provides a synthesis reactor for oilfield fracturing fluid, including a reactor body 1 for synthesizing oilfield fracturing fluid. An addition pipe 2 and a main fluid pipe 16 are fixedly connected to both sides of the top of the reactor body 1. A fixing seat 3 is fixedly connected to the inner side of the addition pipe 2. The fixing seat 3 includes elastic strips 4 on both sides. A filter screen 5 is slidably connected to the inner side of the fixing seat 3. An outer plate 8 is fixedly connected to one end of the filter screen 5 located outside the fixing seat 3. Both ends of the outer plate 8 have locking holes 9. A sliding rod 10 is fixedly connected to the outer side of the addition pipe 2 directly above the outer plate 8. A sliding plate 11 is slidably connected to the outer side of the sliding rod 10. Both ends of the bottom of the sliding plate 11 are fixedly connected to the locking rods 12. The locking rods 12 have two locking holes 9 on their inner sides. The inner side of the adding tube 2 is rotatably connected to the rotating rod 13 below the fixed base 3. Both ends of the outer side of the rotating rod 13 are fixedly connected to the striking blocks 14. The inside of the adding tube 2 has a mounting groove for the sliding of the outer plate 8. The area of ​​the mounting groove is smaller than the side of the fixed base 3 near the outer plate 8. A No. 1 motor is fixedly connected to the outer side of the adding tube 2. One end of the rotating rod 13 extends out of the adding tube 2 and is fixedly connected to the output end of the No. 1 motor. The two striking blocks 14 are located directly below the two spring bars 4.

[0026] Slide the sliding plate 11 upwards and insert the filter screen 5 into the addition tube 2 through the mounting groove, so that the filter screen 5 slides into the fixing seat 3. Release the sliding plate 11, so that it drives the locking rod 12 to insert into the locking hole 9 and fix the filter screen 5. Add the main liquid into the vessel body 1 through the main liquid tube 16 and add the additive into the vessel body 1 through the addition tube 2. The additive will fall above the filter screen 5. Drive the rotating rod 13 to rotate through the No. 1 motor. The striking block 14 will rotate accordingly and strike the two spring bars 4. The spring bars 4 will cause the two ends of the filter screen 5 to vibrate up and down to screen the additive.

[0027] When the striking block 14 strikes the spring bar 4, the spring bar 4 quickly converts this impact force into the up-and-down vibration of the filter screen 5. Since the spring bar 4 and the filter screen 5 are connected by a sliding connection, the filter screen 5 can achieve flexible and uniform up-and-down vibration under the drive of the spring bar 4. The fixed seat 3 not only ensures that the filter screen 5 will not deviate from the predetermined position during vibration, but also makes the vibration of the filter screen 5 more concentrated and efficient through its limiting effect on the filter screen 5. This allows the filter screen 5 to maintain a certain stability and regularity during vibration, which not only improves the screening efficiency of the device, but also ensures the stability and reliability of the screening process.

[0028] Please see Figures 1-5 Two elastic bars 4 are fixedly connected to a squeezing ring 6 on the side away from each other. Several support rings 7 are fixedly connected inside the squeezing ring 6. The side of the two squeezing rings 6 away from each other is in close contact with the inner wall of the adding tube 2. The top of the adding tube 2 is rotatably connected to a rotating shaft 15. There are three support rings 7 inside the same squeezing ring 6. The support rings 7 are elliptical. The top of the vessel body 1 is fixedly connected to a No. 2 motor. Its output end is fixedly connected to the top of the rotating shaft 15. Several stirring blades are fixedly connected to the outside of the rotating shaft 15 inside the vessel body 1. The bottom of the inner cavity of the vessel body 1 is fixedly connected to a base frame. The bottom of the rotating shaft 15 is rotatably connected to the inside of the base frame. Several support feet are fixedly connected to the bottom of the outside of the vessel body 1. The bottom of the vessel body 1 is fixedly connected to a liquid outlet pipe 17. A valve is fixedly connected to the outside of the liquid outlet pipe 17. The filter screen 5, squeezing ring 6 and support ring 7 are all elastic structures.

[0029] When the spring bar 4 moves, it drives the extrusion ring 6 to move up and down. The extrusion ring 6 is pushed by the support ring 7 to stick tightly to the inner wall of the addition pipe 2 to prevent the additive from falling off. The screened additive enters the reactor body 1. The second motor is started to drive the rotating shaft 15 to rotate, which drives the stirring blade to stir the main liquid and additive in the reactor body 1 to synthesize fracturing fluid. Then the valve on the outlet pipe 17 is opened to discharge the synthesized oilfield fracturing fluid.

[0030] When the spring bar 4 vibrates due to the impact force of the striking block 14, the support ring 7 ensures that the extrusion ring 6 always maintains a tight fit with the inner wall of the addition tube 2. This design effectively avoids the possibility of gaps between the extrusion ring 6 and the addition tube 2 during the vibration of the filter screen 5, preventing the additives above the filter screen 5 from accidentally falling off. This not only improves the screening accuracy but also ensures the purity and consistency of the raw materials during the synthesis reaction.

[0031] The working principle and usage process of this utility model are as follows: Slide the sliding plate 11 upwards, insert the filter screen 5 into the addition pipe 2 through the installation groove, so that the filter screen 5 slides into the fixed seat 3. Release the sliding plate 11, so that it drives the clamping rod 12 to insert into the clamping hole 9, fix the filter screen 5, add the main liquid into the vessel body 1 from the main liquid pipe 16, and add the additive into the vessel body 1 from the addition pipe 2. The additive will fall above the filter screen 5. Drive the rotating rod 13 to rotate through the first motor, and the striking block 14 will rotate accordingly and strike the two spring bars 4. The spring bars 4 drive the two ends of the filter screen 5 to vibrate up and down, and screen the additive. When the spring bars 4 move, they drive the squeezing ring 6 to move up and down. The squeezing ring 6 is pushed by the support ring 7 to stick tightly to the inner wall of the addition pipe 2 to prevent the additive from falling. The screened additive enters the vessel body 1. Start the second motor to drive the rotating shaft 15 to rotate, and drive the stirring blade to stir the main liquid and additive in the vessel body 1 to synthesize fracturing fluid. Then open the valve on the outlet pipe 17 to discharge the synthesized oilfield fracturing fluid.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
