Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oil and gas exploitation, in particular to a split pry design super-high pressure cyclone sand remover. BACKGROUND

[0002] The split pry design super-high pressure cyclone sand remover is a modular equipment for super-high pressure sand-containing medium purification treatment. In the super-high pressure working condition, the precise docking of a few core interfaces of pry blocks is required. In the field integration of the split pry equipment, the docking of the pry block base is a key step to ensure the alignment of the core interface axis, which directly affects the interface docking accuracy and system operation reliability.

[0003] However, in actual operation, the bases of the pry blocks are independently designed as steel structures, the core interfaces are fixed at the preset positions of different bases, and the alignment of the interface axis depends on the precise positioning between the bases. In the prior art, the pry block to be docked is hoisted to the target area by hoisting equipment, and then the base is pushed to slide along the ground to adjust the position to try to make the axes of the core interfaces coincide. However, the alignment accuracy of the interface axis is extremely high in the super-high pressure working condition, and factors such as the difference in ground flatness and uneven sliding resistance of the sled bottom will make it difficult to accurately control the direction and displacement of the base during movement. Therefore, it is often necessary to repeatedly adjust the hoisting angle and the position of the base to preliminarily position the interface. The whole process is time-consuming, and the docking difficulty of the base will indirectly cause problems such as interface sealing risk. Therefore, the present application provides a split pry design super-high pressure cyclone sand remover which can quickly and accurately position the pry block base and reduce the docking difficulty of the core interface.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0018] Please refer to Figures 1-9As shown, the present invention is a skid-mounted ultra-high pressure cyclone sand separator, including a base 1, a connecting seat 2, a bearing plate 3, a cyclone sand separator assembly 28, a diversion manifold 29, a sand discharge manifold 30, and a sand flushing manifold 31. The cyclone sand separator assembly 28 is fixedly installed in the base 1. The diversion manifold 29, the sand discharge manifold 30, and the sand flushing manifold 31 are respectively fixedly installed on the three bearing plates 3, and the diversion manifold 29, the sand discharge manifold 30, and the sand flushing manifold 31 are all connected to the cyclone sand separator assembly 28 through connecting pipes. Each connecting seat 2 is connected to the base 1. Two first hanging rods 4 are fixedly installed on both sides of each bearing plate 3. The first hanging rods 4 are connected to external hoisting equipment through hanging ropes. Two symmetrically arranged first cavities 5 are opened on the connecting seat 2. A sliding seat 6 is slidably installed in each first cavity 5. The two sliding seats 6 are driven by a linkage component to move in opposite directions. Two abutment rods 7 are provided on each sliding seat 6. Each connecting seat 2 has a central hole 10, and each bearing plate 3 has a round block 11 fixedly installed at the bottom. The round block 11 is connected to the linkage component and is slidably connected to the central hole 10. When the external hoisting equipment installs the bearing plate 3 onto the connecting seat 2 by connecting the first hanging rod 4 with the hoisting rope, as the round block 11 slides into the central hole 10, the round block 11 drives the two sliding seats 6 to approach the bearing plate 3 through the linkage component, so that the four abutting rods 7 abut against and clamp the bearing plate 3, thereby correcting the direction of the bearing plate 3, so that the docking pipe on the bearing plate 3 is coaxial with the cyclone sand separator component 28.

[0019] In one embodiment, it should be noted that the cyclone separator assembly 28, the diversion manifold 29, the sand discharge manifold 30, the sand flushing manifold 31, and the external hoisting equipment described in this invention are all prior art. This invention does not improve them. Therefore, it is not necessary to disclose their specific mechanical and circuit structures, and this does not affect the integrity of this invention.

[0020] The working principle of the present invention is as follows: When the external hoisting equipment hoists the bearing plate 3 by connecting the first hanging rod 4 with the hoisting rope, it is easy to cause the bearing plate 3 to shift. This is mainly due to the elastic deformation of the hoisting rope, uneven force, and the hook not being aligned with the center of gravity, which causes tilting. The weight asymmetry of the integrated module of the bearing plate 3 also causes the center of gravity to shift, which is superimposed by the wind load in the field, pushing it to translate or rotate. In the installation, for example, the butt joint of the sand drainage manifold 30 and the cyclone desander assembly 28, since the sand drainage manifold 30 is fixedly installed on the bearing plate 3, the sand drainage manifold 30 is communicated with the cyclone desander assembly 28 through the butt joint pipe, therefore, the connecting seat 2 needs to be installed on the base 1 first, and then the first hanging rod 4 on both sides of the bearing plate 3 is connected through the external hoisting equipment, and the bearing plate 3 is hoisted above the connecting seat 2; in the initial state, although the lifting rope is straight, the bearing plate 3 will still be offset when the external hoisting equipment hoists the bearing plate 3 through the lifting rope, if the round block 11 at the bottom of the bearing plate 3 is directly inserted into the center hole 10 of the connecting seat 2, the butt joint pipe on the bearing plate 3 and the axis of the cyclone desander assembly 28 will be easily dislocated; when the round block 11 is inserted along the center hole 10, the round block 11 triggers the linkage assembly to move, drives the two sliding seats 6 to move towards each other along the first cavity 5, the four abutting rods 7 are first moved with the sliding seat 6 to contact the side wall of the bearing plate 3, so as to avoid rigid collision and establish a stable force applying basis; then a symmetrical lateral force is applied to the offset bearing plate 3 to form a correction torque to offset the offset torque, so that the bearing plate 3 is restored to be horizontal; finally, the bearing plate 3 is clamped and locked to ensure that the butt joint pipe on the bearing plate 3 is coaxial with the cyclone desander assembly 28, so that the offset angle of the bearing plate 3 is corrected by symmetrical clamping, the butt joint pipe on the bearing plate 3 is accurately aligned with the axis of the cyclone desander assembly 28, and manual pushing of the bearing plate 3 is not needed.

[0021] As shown in Figures 1-4 As a preferred embodiment of the present application, two second hanging rods 9 are fixedly installed on both sides of each connecting seat 2, and the second hanging rods 9 are connected with the external hoisting equipment through the lifting rope.

[0022] In actual application, the connecting seat 2 is hoisted to the preset installation position of the base 1 through the second hanging rods 9 on both sides of the connecting seat 2, since the connecting seat 2 is only a positioning structure and does not integrate heavy components such as the flow distribution manifold 29 and the sand drainage manifold 30, the connecting seat 2 is light in weight and small in size, can be quickly adjusted to realize accurate butt joint with the base 1; after the connecting seat 2 is fixed, the bearing plate 3 is hoisted to the connecting seat 2, compared with the integrated hoisting of the connecting seat 2 and the bearing plate 3, the step-by-step hoisting can shorten the butt joint time.

[0023] As shown in Figures 1-6As shown, as a preferred embodiment of the present application, the linkage assembly comprises a second cavity 23, an L-shaped slider 8, a fixed cylinder 15, a plug rod 17 and a driving assembly, the second cavity 23 is arranged in the connecting seat 2, the second cavity 23 is communicated with the first cavity 5, two fixed cylinders 15 are fixedly installed in the second cavity 23, and the two fixed cylinders 15 are symmetrically arranged about the center hole 10, one plug rod 17 is slidingly installed in each fixed cylinder 15, and the two plug rods 17 are driven to move towards each other by the driving assembly, the two plug rods 17 move along the radial direction of the center hole 10, and two L-shaped sliders 8 are slidingly installed in the second cavity 23, one end of the L-shaped slider 8 is fixedly connected with the sliding seat 6, the other end of the L-shaped slider 8 is fixedly connected with the plug rod 17, there are a sliding seat 6 and a plug slot 12 distributed on both sides of the center hole 10, the sliding seat 6 and the plug slot 12 connected at both ends of the L-shaped slider 8 are distributed on the opposite sides, and the driving assembly is connected with the circular block 11, when the circular block 11 is slidingly inserted into the center hole 10, the circular block 11 drives the two plug slots 12 to move away from each other through the driving assembly.

[0024] Specifically, the driving assembly comprises a plug block 13, an inclined edge 14 and a sliding groove 16, the sliding groove 16 is arranged in the fixed cylinder 15, the plug block 13 is slidingly installed in the sliding groove 16, and the plug block 13 is fixedly connected with the plug rod 17, the inclined edge 14 is arranged on the plug block 13, and the horizontal height of one end of the inclined edge 14 close to the axis of the center hole 10 is lower than the horizontal height of the other end of the inclined edge 14 away from the axis of the center hole 10, and the plug block 13 partially extends into the center hole 10 in the initial state, when the circular block 11 is slidingly inserted into the center hole 10, the circular block 11 abuts against the inclined edge 14 and extrudes the plug block 13 into the sliding groove 16.

[0025] Specifically, two plug slots 12 are arranged on the circular block 11, and the two plug slots 12 are symmetrically arranged about the circular block 11, the plug block 13 is connected with the groove bottom of the sliding groove 16 through a spring 18, and the pre-tightening force of the spring 18 makes the plug block 13 move away from the sliding groove 16, when the circular block 11 is slidingly inserted into the center hole 10, the plug block 13 is retracted into the sliding groove 16 and compresses the spring 18, at this time, the plug block 13 drives the plug rod 17 and the L-shaped slider 8 to move synchronously, so that the sliding seat 6 is close to the bearing plate 3, and then the plug slot 12 is aligned with the sliding groove 16, and the plug block 13 is slidingly connected with the plug slot 12.

[0026] Specifically, the connecting seat 2 is provided with an unlocking hole 22 at both ends, the unlocking hole 22 is communicated with the second cavity 23, a push rod 24 is slidingly inserted into the unlocking hole 22, a convex block 25 is fixedly installed at one end of the push rod 24, and the push rod 24 is driven to move by a driving source, when the driving source drives the push rod 24 to make the convex block 25 pass through the unlocking hole 22, the convex block 25 pushes the L-shaped slider 8 to move, so that the L-shaped slider 8 drives the plug rod 17 and the plug block 13 to move, thereby making the plug block 13 move out of the plug slot 12.

[0027] In one embodiment, the bottom of the circular block 11 is provided with a second chamfer 27, and the top of the central hole 10 is provided with a first chamfer 26. The driving source can be manually driven, or other mechanisms that can realize the linear reciprocating motion and rotational motion of the push rod 24 can be used. This embodiment does not make specific limitations here.

[0028] In practical application, before the circular block 11 is inserted into the central hole 10, the insert block 13 extends into the central hole 10 under the preload of the spring 18. The sliding seat 6 is in the initial position away from the axis of the central hole 10. When the second chamfer 27 at the bottom of the circular block 11 is aligned with the first chamfer 26 at the top of the central hole 10 and inserted, the side wall of the circular block 11 first abuts against the inclined surface of the inclined edge 14 on the insert block 13. As the circular block 11 continues to move down, the inclined edge 14 is pushed by the force to push the insert block 13 to slide along the slide groove 16 away from the central hole 10. The spring 18 is compressed, and the insert block 13 drives the insert rod 17 to move synchronously. The insert rod 17 pulls the sliding seat 6 along the first cavity 5 towards the support plate 3 through the L-shaped slider 8 until the abutting rod 7 on the sliding seat 6 abuts against the side wall of the support plate 3. The offset of the support plate 3 is corrected by symmetrical clamping on both sides, so that the interface on the support plate 3 is coaxial with the interface of the cyclone desander assembly 28. When the circular block 11 is fully inserted into the central hole 10, the slot 12 on the circular block 11 aligns with the axis of the slide groove 16. The spring 18 releases its preload, pushing the insert block 13 back to its original position. The insert block 13 then inserts into the slot 12, achieving a rigid lock between the circular block 11 and the connecting seat 2. Figure 6 As shown in the example, this achieves automatic locking between the connecting seat 2 and the bearing plate 3. At this time, the sliding seat 6 will also reset and return to a position away from the bearing plate 3. When unlocking is required, the protrusion 25 at one end of the push rod 24 is manually inserted into the unlocking hole 22, causing the protrusion 25 to push the L-shaped slider 8. The L-shaped slider 8 pulls the insert block 13 out of the slot 12 through the insert rod 17. At this time, rotating the push rod 24 allows the protrusion 25 to rotate in the second cavity 23. At this time, the protrusion 25 will be unable to pass through the unlocking hole 22 and will be restricted in the second cavity 23. Then the L-shaped slider 8 will be stationary, so that the insert block 13 will always be away from the slot 12, thereby unlocking the carrier plate 3 and the connecting seat 2. At this time, the external hoisting equipment can lift the carrier plate 3 away from the connecting seat 2.

[0029] like Figures 1-9 As shown, in a preferred embodiment of the present invention, the abutment rod 7 and the sliding seat 6 are detachably connected, and the abutment rod 7 and the sliding seat 6 are threadedly connected. Two baffles 19 are slidably installed in each of the first cavities 5. The baffles 19 are driven to move by the output source. When the abutment rod 7 is removed from the sliding seat 6, the output source drives the two baffles 19 to move closer, and the two baffles 19 block the first cavity 5.

[0030] Specifically, the two shutters 19 are fixedly installed with magnets 21 and handles 20 on opposite sides, and the two handles 20 are arranged in a staggered manner.

[0031] In one case of the embodiment, the output source can be manually driven, and can also be other mechanisms capable of realizing linear reciprocating motion, which is not specifically limited herein.

[0032] In actual application, when the bearing plate 3 is installed, the abutting rod 7 can be rotated and removed, the output source drives the two shutters 19 to move towards each other along the first cavity 5, until the magnets 21 on the two shutters 19 are attracted to each other, realizing the sealing and plugging of the first cavity 5, avoiding dust and sundries from entering the first cavity 5 and the second cavity 23, and preventing the linkage assembly from being stuck or rusted; When the abutting rod 7 needs to be reinstalled or the sliding seat 6 is used, the two shutters 19 can be manually pushed apart through the staggered handles 20, so that the internal space of the first cavity 5 is exposed, facilitating operation.

[0033] The above describes one embodiment of the application in detail, but the content described is only a preferred embodiment of the application and cannot be considered as limiting the scope of the application. Any equivalent changes and improvements made in the scope of the application should still belong to the scope of the patent.

6. A skid-mounted ultra-high pressure cyclone sand separator according to claim 5, characterized in that, The connector (2) has unlocking holes (22) at both ends. The unlocking holes (22) are connected to the second cavity (23). A push rod (24) is slidably inserted into the unlocking hole (22). A protrusion (25) is fixedly installed at one end of the push rod (24). The push rod (24) is driven by a drive source to move. When the drive source drives the push rod (24) to make the protrusion (25) pass through the unlocking hole (22), the protrusion (25) pushes the L-shaped slider (8) to move, so that the L-shaped slider (8) drives the insert rod (17) and the insert block (13) to move, thereby making the insert block (13) move out of the slot (12).

7. A skid-mounted ultra-high pressure cyclone sand separator according to claim 1, characterized in that, The abutment rod (7) and the sliding seat (6) are detachably connected, and the abutment rod (7) and the sliding seat (6) are threadedly connected. Two baffles (19) are slidably installed in each of the first cavities (5). The baffles (19) are driven to move by the output source. When the abutment rod (7) is removed from the sliding seat (6), the output source drives the two baffles (19) to move closer and the two baffles (19) seal the first cavity (5).

8. A skid-mounted ultra-high pressure cyclone sand separator according to claim 7, characterized in that, Magnets (21) and handles (20) are fixedly installed on opposite sides of the two covers (19), and the two handles (20) are staggered.
