Description

Technical Field

[0001] This utility model relates to the field of acid circulation pump installation technology, and specifically to an acid circulation pump that is easy to connect. Background Technology

[0002] In the metal processing industry, such as the production of steel and stainless steel, pickling is an important process for removing oxide scale and impurities from the metal surface. When stainless steel is hot-rolled from billet into plates or profiles, an oxide layer will form on the surface, which must be pickled to improve its appearance and corrosion resistance. This requires an acid circulation pump to circulate the acid in the pickling system, so that the acid can fully contact the metal surface and ensure the pickling effect. The acid circulation pump is used to transport and circulate the acid, providing a stable supply of materials and environmental conditions for the reaction.

[0003] During pump operation, it is essential to continuously monitor various operating parameters, such as flow rate, pressure, temperature, current, and voltage. These parameters should be acquired in real time using instruments such as flow meters and pressure gauges installed on the pipeline, as well as the pump's built-in temperature sensors and current transformers, and compared with the set values. If any abnormal parameters are detected, the cause should be analyzed promptly and appropriate measures taken.

[0004] Existing acid circulation pumps often use excessive bolts for temporary fixation during installation. This requires aligning each bolt with its hole, inserting it, and tightening it. To ensure installation accuracy and sealing, multiple tightening operations are necessary, following a specific sequence and torque requirements. This process is quite cumbersome. When the acid circulation pump needs repair or replacement, removing the bolts can be difficult. The acid environment can cause the bolts to rust and corrode, tightening the fit between the bolt and nut, even leading to seizing. This increases the difficulty of disassembly, sometimes requiring special tools and methods to remove the bolts, and may even damage the bolts and the equipment. Utility Model Content

[0005] Given that the installation of the acid circulation pump requires aligning each bolt hole individually, which is a rather cumbersome process, and that the acid environment may cause the bolts to rust or corrode when the pump needs repair or replacement, making the fit between the bolts and nuts tighter or even causing them to seize, the disassembly process becomes more difficult.

[0006] To solve the above technical problems, this utility model provides the following technical solution: an acid circulation pump that is easy to connect, comprising: an acid circulation pump body and a rectangular fixing plate, wherein the acid circulation pump body is provided with several support rods, and the several support rods are all connected to the rectangular fixing plate, a rectangular limiting hole is provided through the vertical surface of the rectangular fixing plate, a rectangular base plate is also provided on the lower surface of the rectangular fixing plate, a U-shaped positioning frame is fixedly provided on the upper surface of the rectangular base plate, a rectangular moving groove is provided on the upper surface of the rectangular base plate, and the same bidirectional threaded rod is connected through the short vertical surface inside the rectangular moving groove, a pair of relatively movable rectangular mounting blocks are fitted on the rod body of the bidirectional threaded rod, and a pair of mutually symmetrical arc-shaped push plates are provided on the upper surface of the rectangular mounting blocks.

[0007] As a preferred embodiment of the conveniently connected acid circulation pump described in this utility model, a pair of limiting rings are provided on the vertical surface of the arc-shaped push plate, a cylindrical rod is provided on the inner ring of the pair of limiting rings, and several rectangular mounting frames are provided through the upper surface of the rectangular base plate.

[0008] As a preferred embodiment of the conveniently connected acid circulation pump of this utility model, a cylindrical guide rod is fixedly connected to the inner ring of the rectangular mounting frame. A rectangular moving block is also provided on the rod body of the cylindrical guide rod, and the rectangular moving block and the cylindrical guide rod are slidably connected. An L-shaped limiting block is also provided on the upper surface of the rectangular moving block.

[0009] As a preferred embodiment of the conveniently connected acid circulation pump described in this utility model, a circular baffle is fixedly provided on the cylindrical guide rod near the circular surface of the rectangular moving block, and a memory spring is also provided on the vertical surface inside the rectangular mounting frame.

[0010] In a preferred embodiment of the conveniently connected acid circulation pump described in this utility model, one end of the memory spring is connected to the short vertical surface of the rectangular mounting frame, and the other end of the memory spring is connected to the vertical surface of the rectangular moving block. A pair of rectangular lifting rods are provided through the bottom surface inside the rectangular mounting frame, and the rectangular lifting rods are slidably connected to the rectangular mounting frame. A stop block is also provided on the upper surface of the pair of rectangular lifting rods.

[0011] As a preferred embodiment of the conveniently connected acid circulation pump of this utility model, an arc-shaped groove is provided through the long vertical surface inside the rectangular moving groove. An arc-shaped docking block is slidably connected to the cross-section of the arc-shaped groove away from the L-shaped limiting block. A U-shaped push-pull handle is also provided on the vertical surface of the arc-shaped docking block. A pair of arc-shaped push blocks are also provided on the vertical surface of the arc-shaped docking block away from the U-shaped push-pull handle. A rubber sleeve is wrapped around the outer ring of the arc-shaped docking block.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0013] 1. The fixing method of this equipment is different from the traditional bolt fixing method. This equipment can temporarily fix the main body of the acid circulation pump through several L-shaped limit blocks. Moreover, this fixing method does not require a lot of time and manpower. Even during disassembly and emergency repair, the time can be greatly reduced, thereby saving the time wasted on disassembly.

[0014] 2. The equipment is also equipped with a device to protect the temporary fixing structure. The temporary fixing structure can be lowered. Before the acid circulation pump body is placed in the appropriate position, the temporary fixing structure is in a retracted state, so as to ensure that the acid circulation pump body will not be broken or damaged when adjusting its position.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments. Example 1

[0025] Reference Figure 1-4 This is the first embodiment of the present invention, which discloses an acid circulation pump that is easy to connect, including: an acid circulation pump body 1 and a rectangular fixing plate 2. The acid circulation pump body 1 is provided with several support rods, and the several support rods are all connected to the rectangular fixing plate 2. A rectangular limiting hole is provided through the vertical surface of the rectangular fixing plate 2. A rectangular base plate 3 is also provided on the lower surface of the rectangular fixing plate 2. A U-shaped positioning frame 4 is fixedly provided on the upper surface of the rectangular base plate 3. A rectangular moving groove 5 is provided on the upper surface of the rectangular base plate 3. The short vertical surface inside the rectangular moving groove 5 is connected through the same bidirectional threaded rod 6. A pair of relatively movable rectangular mounting blocks 7 are fitted on the rod body of the bidirectional threaded rod 6. A pair of symmetrical arc-shaped push plates 8 are provided on the upper surface of the rectangular mounting blocks 7.

[0026] A pair of limiting rings 9 are provided on the vertical surface of the arc-shaped push plate 8. A cylindrical rod 10 is provided on the inner ring of the pair of limiting rings 9. Several rectangular mounting frames 11 are provided through the upper surface of the rectangular base plate 3. A cylindrical guide rod 12 is fixedly connected to the inner ring of the rectangular mounting frame 11. A rectangular moving block 13 is also provided through the rod body of the cylindrical guide rod 12. The rectangular moving block 13 is slidably connected to the cylindrical guide rod 12. An L-shaped limiting block 14 is also provided on the upper surface of the rectangular moving block 13.

[0027] A circular baffle 15 is fixedly installed on the circular surface of the cylindrical guide rod 12 near the rectangular moving block 13. A memory spring 16 is also installed on the vertical surface inside the rectangular mounting frame 11. One end of the memory spring 16 is connected to the short vertical surface of the rectangular mounting frame 11, and the other end of the memory spring 16 is connected to the vertical surface of the rectangular moving block 13. A pair of rectangular lifting rods 17 are installed through the bottom surface inside the rectangular mounting frame 11, and the rectangular lifting rods 17 are slidably connected to the rectangular mounting frame 11.

[0028] Before operation, place the acid circulation pump body 1 in a suitable position. Note: Ensure that the pair of rectangular fixing plates 2 connected to the acid circulation pump body 1 fit snugly against the U-shaped positioning frame 4. After placement, check the alignment. Then, start the drive motor directly. The output end of the drive motor is connected to the bidirectional threaded rod, and the threads on the bidirectional threaded rod are meshed with the threaded grooves on the inner ring of the pair of rectangular mounting blocks 7. As the drive motor starts, the pair of rectangular mounting blocks 7 will move relative to each other. Because the upper surface of the pair of rectangular mounting blocks 7 is provided with a pair of symmetrical arc-shaped push plates 8, when the arc-shaped push plate 8 contacts the L-shaped limit block 14, the L-shaped limit block 14 will move forward under the continuous pushing force of the arc-shaped push plate 8, so that the L-shaped limit block 14 gradually enters the rectangular limit hole on the vertical surface of the rectangular fixing plate 2, ultimately achieving a temporary fixing effect. Example 2

[0029] Reference Figure 3 , 5 6. This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a pair of rectangular lifting rods 17 are provided through the bottom surface inside the rectangular mounting frame 11, and the rectangular lifting rods 17 are slidably connected to the rectangular mounting frame 11. A stop block is also provided on the upper surface of the pair of rectangular lifting rods 17. An arc-shaped groove 18 is provided through the long vertical surface inside the rectangular moving groove 5. An arc-shaped docking block 19 is slidably connected to the section of the arc-shaped groove 18 away from the L-shaped limiting block 14. A U-shaped push-pull handle 20 is also provided on the vertical surface of the arc-shaped docking block 19. A pair of arc-shaped push blocks 21 are also provided on the vertical surface of the arc-shaped docking block 19 away from the U-shaped push-pull handle 20. A rubber sleeve 22 is wrapped around the outer ring of the arc-shaped docking block 19.

[0030] In use, before starting the operation of Example 1, the arc-shaped connecting block 19 is pulled out directly through the U-shaped push-pull handle 20. As the arc-shaped connecting block 19 is pulled out, the rectangular mounting frame 11 will continue to descend under its own weight. After descending to the lowest point, the height of the upper surface of the L-shaped limiting block 14 will be lower than the height of the upper surface of the rectangular base plate 3. At this time, the acid circulation pump body 1 can be placed in a suitable position first. After placement, the arc-shaped connecting block 19 can be inserted back. Then, the operation steps in Example 1 can be followed.

[0031] The remaining structure is the same as that in Example 1.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
