Description

Technical Field

[0001] The invention belongs to the technical field of material mixing and dispersion, and in particular relates to a fracturing fluid raw material dispersing and mixing device. Background Art

[0002] The drilling fracturing fluid is mainly made by dispersing and mixing polyacrylamide dry powder into water. At present, the fracturing fluid is mainly prepared in a prefabricated manner. The reason is that the existing fracturing fluid preparation devices are mainly stirring devices, which can only produce quantitatively in batches. After production, the fracturing fluid is filled into ton barrels and finally sent to the construction site. This method not only increases the filling, storage and transportation costs, but also the fracturing fluid after mixed filling is prone to stratification, resulting in a decrease in the uniformity of the dispersion of polyacrylamide dry powder in water during use, affecting the use effect of the fracturing fluid. On the other hand, the existing stirring device usually uses a hopper to directly drop the polyacrylamide dry powder into the stirring device from above the water. Some of the dry powder sticks to each other after entering the water, forming "fish eyes" of undissolved polymer clumps and bubbles, which affects the dispersion effect of the dry powder. Summary of the invention

[0003] In order to solve the deficiencies of the prior art, the present invention provides a fracturing fluid raw material dispersing and mixing device, which can effectively improve the dispersion effect of polyacrylamide dry powder, and can produce it continuously, which is convenient for use at the drilling site.

[0004] In order to achieve the purpose of the present invention, the following scheme is proposed:

[0005] A fracturing fluid raw material dispersing and mixing device comprises an outer barrel, a hopper and a stirring barrel.

[0006] A partition is provided in the middle of the outer barrel, a through hole is opened on the partition, and an output pipe is provided at the bottom of the outer barrel;

[0007] The hopper is arranged at the upper end of the inner part of the outer barrel body, the top of the hopper is a feed pipe, the feed pipe protrudes from the top of the outer barrel body, and the lower end of the hopper is provided with a drop pipe;

[0008] The mixing barrel passes through the partition coaxially, the upper outer wall of the mixing barrel is provided with meshes, and the meshes are all located above the partition, the mixing barrel is arranged to rotate around the axis, and blades are arranged inside the mixing barrel; a water pipe passes through the bottom of the outer barrel body and is coaxially arranged at the bottom of the mixing barrel;

[0009] A connecting ring is provided in the feeding pipe, and a lifting rod coaxial with the feeding pipe is passed through the connecting ring. The circumferential position of the lifting rod is kept constant. A disc is provided at the lower end of the lifting rod, and a flange is provided at the top of the lifting rod, which is located above the connecting ring. A cylindrical spring is provided on the lifting rod sleeve, which is located between the disc and the connecting ring, and a trigger is provided at the lower end of the disc.

[0010] The drop pipe is coaxially arranged on the top of the mixing barrel and communicated with the inside of the mixing barrel. An arc-shaped guide block is arranged inside the mixing barrel. The arc axis is coaxial with the mixing barrel. Both ends of the top surface of the guide block are inclined surfaces, and the highest point of the guide block is located in the middle.

[0011] When the bottom surface of the flange abuts against the top surface of the connecting ring, the bottom surface of the trigger is higher than the lower edge of the inclined surfaces at both ends of the guide block, the disc is inserted in the drop tube, and the cylindrical spring is in a compressed state; when the trigger contacts the top surface of the middle part of the guide block, the lifting rod rises upward, and there is a gap between the disc and the top pipe opening of the drop tube.

[0012] The beneficial effects of the present invention are:

[0013] 1. While the mixing barrel is rotating and stirring, the guide block and the actuator cooperate to control the lifting of the disc, so as to automatically control the feed amount according to the rotation speed of the mixing barrel, so as to achieve the purpose of batch, small amount and accurate control of feed, so as to avoid more agglomeration when the dry powder feed amount is too large.

[0014] 2. After the dry powder is discharged from the hopper, it first enters the mixing barrel to complete the first dispersion and mixing, and then performs the second mixing outside the mixing barrel and in the space above the partition, which can effectively improve the dispersion and mixing effect.

[0015] 3. The mixed liquid after the two mixings can be temporarily stored at the bottom of the outer barrel to meet the purpose of continuous output. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] like Figures 1 to 3 As shown, a fracturing fluid raw material dispersing and mixing device includes: an outer barrel 1, a hopper 2 and a stirring barrel 3.

[0028] A horizontal partition 11 is provided at the middle of the outer barrel 1 in the height direction. A through hole 111 is provided on the partition 11. An output pipe 12 is provided at the bottom of the outer barrel 1 for outputting the fracturing fluid.

[0029] The hopper 2 is arranged at the upper end of the outer barrel body 1, and the top of the hopper 2 is a feed pipe 21, which protrudes from the top of the outer barrel body 1. When discharging the material for the first time, a funnel can be connected to the feed pipe 21, and the polyacrylamide dry powder can be smoothly put into the hopper 2 using the funnel. The polyacrylamide dry powder can also be directly put into the hopper 2 through a pipeline. A drop pipe 22 is provided at the lower end of the hopper 2.

[0030] The mixing barrel 3 coaxially passes through the partition 11, and the partition 11 is located at the middle position of the height of the mixing barrel 3. The upper outer wall of the mixing barrel 3 is provided with meshes 31, and the meshes 31 are all located above the partition 11. The mixing barrel 3 is rotatably arranged around the axis, and blades 32 are arranged inside the mixing barrel 3 to improve the dispersion effect of the polyacrylamide dry powder; a water pipe 6 passes through the bottom of the outer barrel body 1 and is coaxially arranged at the bottom of the mixing barrel 3 to supply water to the inside of the mixing barrel 3.

[0031] Specifically, a connecting pipe 33 is coaxially provided at the bottom of the mixing barrel 3, and the connecting pipe 33 is connected to the inside of the mixing barrel 3. The connecting pipe 33 passes through the bottom of the outer barrel body 1, and a rotating sealing structure is provided between the outer wall of the connecting pipe 33 and the outer barrel body 1 to prevent leakage. Specifically, a rotating sealing ring of a suitable model can be selected for sealing according to the size of the connecting pipe 33. A driving motor 13 is provided on the outside of the outer barrel body 1. The driving motor 13 is connected to the connecting pipe 33 through a belt transmission structure, and is used to drive the mixing barrel 3 to rotate. The connecting pipe 33 and the driving motor 13 can also be connected through a gear transmission structure; the water pipe 6 is detachably inserted into the connecting pipe 33, and is used to supply water to the inside of the mixing barrel 3, and the water pipe 6 can be removed after use to facilitate cleaning and discharge of residual liquid in the mixing barrel 3.

[0032] A connecting ring 23 is provided in the feeding tube 21, and a lifting rod 5 coaxial with the blanking tube 22 is passed through the connecting ring 23. The circumferential position of the lifting rod 5 remains fixed, that is, the lifting rod 5 does not rotate along the circumference. A disc 51 is provided at the lower end of the lifting rod 5, and its outer wall matches the inner hole of the blanking tube 22. A flange 52 is provided at the top of the lifting rod 5, which is located above the connecting ring 23. The lifting rod 5 is sleeved with a cylindrical spring 53, which is located between the disc 51 and the connecting ring 23. A trigger 54 is provided at the lower end of the disc 51.

[0033] The drop pipe 22 is coaxially arranged on the top of the mixing barrel 3 and is connected with the inside of the mixing barrel 3. An arc-shaped guide block 34 is arranged inside the mixing barrel 3, and its arc axis is coaxial with the mixing barrel 3. Both ends of the top surface of the guide block 34 are inclined surfaces, that is, the two inclined surfaces are respectively inclined toward the upper sides of the two ends of the guide block 34, and the highest point of the guide block 34 is located in the middle position thereof.

[0034] like Figure 1 As shown, when the bottom surface of the flange 52 abuts against the top surface of the connecting ring 23, the bottom surface of the trigger 54 is higher than the lower edge of the inclined surfaces at both ends of the guide block 34. At this time, the disc 51 is inserted into the blanking tube 22, and the cylindrical spring 53 is in a compressed state. It can be seen that the purpose of setting the cylindrical spring 53 is to apply downward pressure to the disc 51, and use the pressure provided by the cylindrical spring 53 to insert the disc 51 into the blanking tube 22, and the purpose of setting the flange 52 is to limit the depth of the disc 51 inserted into the blanking tube 22 and prevent the lifting rod 5 from falling. Figure 2As shown, when the trigger 54 contacts the top surface of the middle part of the guide block 34, the lifting rod 5 rises upward, and there is a gap between the disc 51 and the top nozzle of the drop tube 22, which is used for the polyacrylamide dry powder to flow downward. At this time, the cylindrical spring 53 will be further compressed. The coordination between the trigger 54 and the guide block 34 is achieved by the rotation of the mixing barrel 3. The mixing barrel 3 drives the guide block 34 to rotate together during the rotation process, so that the guide block 34 actively approaches the trigger 54 and then actively separates from the trigger 54. When the guide block 34 and the trigger 54 are not coordinated, under the action of the cylindrical spring 53, the disc 51 is inserted into the drop tube 22 to form a seal to prevent the dry powder from falling into the mixing barrel 3. When the guide block 34 moves toward the trigger 54, the inclined surface of the guide block 34 facing the trigger 54 will first contact the bottom surface of the trigger 54, and then use the inclined surface to push the trigger 54 upward, so that the lifting rod 5 rises, thereby opening the disc 51 that closes the drop tube 22. When the trigger 54 moves to the highest position of the guide block 34, the distance between the disc 51 and the upper end of the drop tube 22 is the largest; when the guide block 34 gradually moves away from the trigger 54, the trigger 54 will also gradually drop from the highest point of the guide block 34, and finally fall to the lowest point under the action of the cylindrical spring 53, and the disc 51 will automatically insert into the drop tube 22 again. The mixing barrel 3 rotates continuously, so that the length of time the disc 51 is open is controlled, so as to achieve the feeding speed of the dry powder, and the feeding speed is matched with the stirring speed of the mixing barrel 3. The faster the stirring speed of the mixing barrel 3, the faster the feeding speed can be, so as to meet the production needs.

[0035] Before producing fracturing fluid, polyacrylamide dry powder is loaded into the hopper 2. During production, water is injected into the mixing barrel 3 through the water pipe 6, and the mixing barrel 3 is rotated at the same time. During the rotation of the mixing barrel 3, the guide block 34 cooperates with the trigger 54 to make the hopper 2 automatically put the polyacrylamide dry powder into the mixing barrel 3. This feeding method can feed in small quantities and multiple times, so that the polyacrylamide dry powder put in each time is quickly dispersed, thereby preventing the formation of "fish eyes". After the polyacrylamide dry powder is put into the mixing barrel 3, it is quickly dispersed into the water under the stirring of the blades 32 inside the mixing barrel 3, completing the first mixing. After the first mixing, the mixed liquid is discharged through the mesh 31. Even if there is agglomerated dry powder, it can be prevented from flowing out by the mesh 31 until the dry powder is completely dispersed and discharged from the mesh 31. The mixed liquid discharged from the mesh 31 will enter the space above the partition 11, and under the action of the mixing barrel 3, the mixed liquid entering the space above the partition 11 will continue to be stirred, completing the second mixing. After two mixings, the mixed liquid at this time can be used as a finished fracturing fluid. After the second mixing, the fracturing fluid will flow from the through hole 111 to the space below the outer partition 11, and temporarily stored at the bottom of the outer barrel 1, and then output through the output pipe 12. The mixed liquid temporarily stored in the space below the partition 11 will also continue to be stirred under the action of the stirring barrel 3 to complete the third mixing, and the third mixing can also be understood as a means to prevent the precipitation of polyacrylamide dry powder. This solution uses the stirring barrel 3 to continuously disperse and mix the polyacrylamide dry powder, and temporarily stores it after two mixings, so as to meet the purpose of continuous output, which is more efficient than the existing batch mixing device. Because this solution can output continuously, it can continuously supply fracturing fluid, so that the device can be used directly at the drilling site, realize on-site dispersion and mixing and meet the purpose of continuous use on the spot, which not only reduces the storage and transportation costs, but also can effectively ensure the quality of the fracturing fluid, avoid the stratification of the fracturing fluid during use, thereby improving the use effect of the fracturing fluid.

[0036] Preferably, Figures 5 to 8 As shown, an annular disk 4 is coaxially arranged above the partition 11, and a through hole 41 corresponding to the through hole 111 is opened on the annular disk 4. The bottom surface of the annular disk 4 is in contact with the top surface of the partition 11. The annular disk 4 is provided with a positioning member 42. The inner wall of the outer barrel 1 is provided with two blocks 14. The positioning member 42 is located between the two blocks 14 along the circumferential direction of the annular disk 4. Figure 5 , Figure 6 As shown, when the positioning member 42 abuts against one of the stoppers 14, the through hole 41 is aligned with the through hole 111, and the mixed liquid above the partition 11 can be smoothly discharged downward. Figure 7 , Figure 8As shown, when the positioning member 42 abuts against another block 14, the through hole 41 is staggered with the through hole 111, and the annular disk 4 covers the through hole 111. At this time, the through hole 111 is in a closed state, and the mixed liquid above the partition 11 cannot be discharged downward through the through hole 111. Which block 14 the positioning member 42 contacts is mainly controlled by the rotation direction of the mixing barrel 3. Because when the mixing barrel 3 rotates, it will definitely drive the mixed liquid above the partition 11 to rotate together, and under the action of the liquid flow, it will drive the annular disk 4 to move and rotate. By controlling the rotation direction of the mixing barrel 3, the rotation direction of the annular disk 4 can be adjusted, so as to control the positioning member 42 to approach one of the blocks 14, so as to achieve the purpose of connecting or blocking the through hole 111. With this structural design, the second mixing time of the mixed liquid can be controlled, which can not only strengthen the control of the mixing effect, but also control the production speed.

[0037] Preferably, Figure 1 , Figure 5 , Figure 7 As shown, a spoiler 43 is provided on the top surface of the annular disk 4, and the spoiler 43 extends radially along the annular disk 4, and a plurality of spoilers 43 are provided along the circumferential array of the annular disk 4, so as to increase the driving force of the mixed liquid on the annular disk 4, so that the mixing barrel 3 can quickly drive the annular disk 4 to rotate through the mixed liquid.

[0038] Preferably, Figure 1 and Figure 2 As shown, paddles 35 are provided at the bottom of the mixing barrel 3 and on the outer wall above the corresponding partition 11 to improve the mixing effect.

[0039] Preferably, Figure 4 As shown, the trigger 54 is arranged at the lower end of a rectangular rod 55, and the rectangular rod 55 is parallel to the lifting rod 5. The upper end of the rectangular rod 55 passes through the flange 52, and the side wall of the flange 52 is penetrated by a locking screw 56 for pressing the rectangular rod 55. This structural setting makes the distance between the trigger 54 and the disc 51 adjustable, so that the rising height of the lifting rod 5 can be controlled, thereby controlling the interval between the disc 51 and the upper end of the drop tube 22 when it is opened, so as to achieve the purpose of adjusting the feeding speed of the hopper 2; and the reason why the rectangular rod 55 is used to connect the trigger 54 is to ensure that the direction of the trigger 54 remains unchanged and prevent the trigger 54 from swinging.

[0040] Further preferably, Figure 4As shown, a plurality of rectangular rods 55 are arranged in a circular array, and a trigger 54 is arranged at the lower end of each rectangular rod 55. The flange 52 is provided with a locking screw 56 corresponding to each rectangular rod 55, which is used to press the corresponding rectangular rod 55. After adopting the above design, the mixing barrel 3 rotates one circle, and the disc 51 can be opened multiple times; in this embodiment, three rectangular rods 55 are arranged, so that the mixing barrel 3 rotates one circle, and the disc 51 can be opened three times, so as to improve the feeding speed; and each rectangular rod 55 can be raised and lowered separately, so that not only the opening size of the disc 51 can be adjusted by controlling the rectangular rod 55, but also some of the triggers 54 can be higher than the guide block 34, so that the triggers 54 higher than the guide block 34 do not participate in controlling the opening of the disc 51, so as to achieve the purpose of controlling the number of triggers 54 cooperating with the guide block 34, thereby improving the control of the material feeding accuracy.

[0041] Further preferably, Figure 4 As shown, the actuating member 54 is a roller structure, and its axis is consistent with the radial direction of the mixing barrel 3 , so as to improve the smoothness of the relative movement between the actuating member 54 and the guide block 34 .

[0042] Preferably, Figure 4 As shown, a rubber ring 57 is provided on the edge of the disk 51 to improve the sealing performance.

[0043] Further preferably, Figure 4 As shown, the cross section of the lifting rod 5 is polygonal to ensure the connection stability and prevent rotation.

[0044] The above description is only a preferred embodiment of the present invention, and is not intended to be the only one or to limit the present invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
