Description

Technical Field

[0001] This utility model relates to the technical field of drag-reducing agents, specifically a heating device for drag-reducing agents used in fracturing. Background Technology

[0002] Drag reducers are high molecular weight compounds that reduce drag. To make drag reducers work better, they often need to be heated. However, existing drag reducer heating devices often cannot heat the drag reducer completely, leaving some unheated drag reducers inside the heating device, which prevents the drag reducer from being applied quickly and effectively.

[0003] A search revealed a utility model patent with Chinese patent publication number CN218637329U: a heating device for a drag-reducing agent used in fracturing. This utility model includes a heating box, a motor mounted on the top of a sliding block, a heating tube connected to the bottom of the motor, a threaded groove on the outer wall of a rotating column, a sliding column mounted on the threaded groove, a fixed hole evenly arranged in a circle on the rotating column, a sliding fixed limiting column mounted in the fixed hole, a connecting plate fixedly connected to the fixed limiting column, a supporting spring on the left side of the connecting plate, and the other end of the supporting spring fixedly connected to the heating box.

[0004] In the above-mentioned existing technical solutions, although the movement of the heating tube can achieve the beneficial effect of heating the drag-reducing agent, since the heating box is square, some material at the corners will still not be heated, and the material adhering to the inner wall of the heating box cannot be scraped off. Therefore, the heating of the drag-reducing agent is not uniform and its practicality is poor. Therefore, a fracturing drag-reducing agent heating device is needed to improve the above problems.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] Please see Figure 1 and Figure 2A heating device for drag-reducing agent used in fracturing includes a heating box 1 and a cover plate 2. The cover plate 2 is placed on the heating box 1, and two feed holes are symmetrically opened on the cover plate 2. The drag-reducing agent is added into the heating box 1 through the two feed holes.

[0028] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 The heating box 1 and the cover plate 2 are limited by two clamping mechanisms. One of the clamping mechanisms includes a movable plate 13. The heating box 1 has an installation groove 11, and the movable plate 13 is slidably connected to the installation groove 11. A rod 12 is fixedly installed on the cover plate 2. A limit block 14 is fixedly installed on the movable plate 13. A slot is opened on the rod 12, and the limit block 14 is slidably connected to the slot. Two telescopic columns 15 are symmetrically fixedly installed on the movable plate 13. The other end of each telescopic column 15 is fixedly connected to the installation groove 11. A spring 16 is fitted on each telescopic column 15. The two ends of each spring 16 are fixedly connected to the movable plate 13 and the installation groove 11, respectively. An L-shaped plate 17 is fixedly installed on the installation groove 11, and a screw is screwed onto the L-shaped plate 17. 19. A top plate 18 is rotatably mounted on the screw 19. Two first stabilizing rods 20 are symmetrically fixed on the top plate 18. One end of each of the two first stabilizing rods 20 is screwed with a bolt 21. The cover plate 2 drives the insertion rod 12 to move. The insertion rod 12 presses against the limiting block 14, which compresses the two telescopic columns 15 and the two springs 16, thereby bringing the moving plate 13 closer to the mounting groove 11. When the limiting block 14 and the slot of the insertion rod 12 coincide, the elastic force of the two springs 16 drives the limiting block 14 to reset and insert into the insertion rod 12, thereby limiting the insertion rod 12 and making the cover plate 2 more stable. By rotating the two bolts 21, the two bolts 21 are made to fit against the moving plate 13, thereby limiting the moving plate 13.

[0029] Please see Figure 1 , Figure 2 and Figure 4The heating chamber 1 is equipped with a heating mechanism, which includes a rotating shaft 3 rotatably connected to the bottom of the heating chamber 1. A locking block 4 is fixedly installed on the rotating shaft 3, and a connecting plate 5 is fixedly installed on the locking block 4. Two heating tubes 6 are symmetrically arranged on the connecting plate 5. A motor 7 is fixedly installed on the cover plate 2, and a stirring shaft 8 is fixedly installed at the output end of the motor 7. A scraper 9 and stirring blades 10 are fixedly installed on the stirring shaft 8. A square groove is opened at the bottom of the stirring shaft 8, and the locking block 4 is engaged with the square groove. The cover plate 2 is placed on the heating chamber 1, so that the locking block 4 and the stirring shaft 8 are engaged. After completing the connection between the clamping block 4 and the stirring shaft 8, start the motor 7. The motor 7 provides power to drive the stirring shaft 8 to rotate. Through the clamping of the stirring shaft 8 and the clamping block 4, the clamping block 4 drives the connecting plate 5 and the two heating tubes 6 to rotate. The two heating tubes 6 heat the drag-reducing agent in the heating box 1. At the same time as the stirring shaft 8 rotates, the scraper 9 and the stirring blade 10 rotate synchronously. The scraper 9 scrapes off the material adhering to the inner wall of the heating box 1, and the stirring blade 10 conveys and stirs the material, so that the drag-reducing agent inside the heating box 1 is fully heated.

[0030] Please see Figure 2 and Figure 4 Two slide rods 22 are symmetrically fixed on the scraper 9, and a slide rail is provided on the cover plate 2. Both slide rods 22 are slidably connected to the slide rail. The arrangement of the two slide rods 22 makes the scraper 9 more stable when rotating.

[0031] Please see Figure 2 and Figure 4 It should also be noted that a stabilizing cylinder 23 is fixedly installed on the cover plate 2, and the stirring shaft 8 is rotatably connected to the stabilizing cylinder 23. The stabilizing cylinder 23 makes the stirring shaft 8 more stable when it rotates.

[0032] Please see Figure 2 and Figure 4 A support plate 24 is fixedly installed on the outer wall of the card block 4, and the bottom end of the stirring shaft 8 is in contact with the support plate 24. The support plate 24 makes the stirring shaft 8 more stable.

[0033] Please see Figure 3 Each of the two mounting slots 11 is fixedly equipped with a second stabilizing rod 25, and the two movable plates 13 are slidably connected to the corresponding second stabilizing rod 25. The two second stabilizing rods 25 make the two movable plates 13 more stable when moving.

[0034] In summary, when using this fracturing drag-reducing agent heating device, the cover plate 2 is placed on the heating box 1, and the locking block 4 is engaged with the stirring shaft 8, completing the connection between the locking block 4 and the stirring shaft 8. The cover plate 2 drives the insertion rod 12 to move. The insertion rod 12 compresses the limiting block 14, causing the two telescopic columns 15 and the two springs 16 to compress, thereby bringing the moving plate 13 closer to the mounting groove 11. When the limiting block 14 and the slot of the insertion rod 12 coincide, the elastic force of the two springs 16 drives the limiting block 14 to reset and reconnect with the insertion rod 12. 2. Insertion is performed to limit the position of the insertion rod 12, thereby making the cover plate 2 more stable and completing the connection between the heating box 1 and the cover plate 2. The two bolts 21 are rotated sequentially until both bolts 21 are in contact with the moving plate 13, thus limiting the position of the moving plate 13. Drag-reducing agent is added into the heating box 1 through the two feed holes. The motor 7 is started. This motor is a commercially available device known to those skilled in the art; we are only using it practically here without making any structural or functional improvements, and we will not go into detail about it here. To elaborate further, the motor is equipped with a matching control switch. The installation position of the control switch is selected according to actual practical needs to facilitate operation and control by the operator. The motor 7 provides power to drive the stirring shaft 8 to rotate. Through the engagement of the stirring shaft 8 and the locking block 4, the locking block 4 drives the connecting plate 5 and the two heating tubes 6 to rotate. The two heating tubes 6 heat the drag-reducing agent in the heating box 1. At the same time as the stirring shaft 8 rotates, the scraper 9 and the stirring blade 10 rotate synchronously. The scraper 9 scrapes off the material adhering to the inner wall of the heating box 1, and the stirring blade 10 conveys and stirs the material, so that the drag-reducing agent inside the heating box 1 is fully heated. When it is necessary to disassemble the cover plate 2, release the multiple bolts 21 that limit the two moving plates 13, and rotate the two screws 19 in sequence. The two screws 19 drive the two top plates 18 to tighten the two moving plates 13, so that the two moving plates 13 drive the two limiting blocks 14 to gradually move away from the two insert rods 12, release the limit on the two insert rods 12, and remove the cover plate 2.

[0035] It should also be noted that the working method of the heating tube 6 in this utility model refers to the heating tube in the referenced patent number CN218637329U.

[0036] 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 and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
