Description

Technical Field

[0001] This utility model relates to the field of diffuser technology, specifically to a diffuser that is easy to assemble and disassemble. Background Technology

[0002] A diffuser is a device generated by a centrifugal compressor, which converts kinetic energy into static pressure energy. The absolute velocity C2 of the airflow at the centrifugal compressor impeller outlet is typically 200-300 m / s. High-energy-head impellers can deliver airflow velocities exceeding 500 m / s. This kinetic energy constitutes a significant proportion of the total energy head supplied to the gas by the impeller.

[0003] However, existing diffusers are generally integrated structures, but during use, flow separation occurs, and frequent surges can damage the diffuser impeller, causing it to wear and even break easily. As a result, the entire diffuser needs to be replaced when the impeller is replaced, which increases the replacement cost. To address these issues, the inventors have proposed a diffuser that is easy to disassemble and assemble to solve the above problems. Utility Model Content

[0004] To address the issue that impellers are prone to wear and even breakage during diffuser use, requiring the entire diffuser to be replaced and increasing replacement costs, the purpose of this invention is to provide a diffuser that is easy to disassemble and assemble.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a diffuser that is easy to assemble and disassemble, comprising a diffuser body, the diffuser body including an inlet pipe, an installation plate fixedly provided at the bottom end of the inlet pipe, a positioning groove provided in the installation plate, a diffuser plate fixedly provided at the top end of the inlet pipe, the inlet pipe and the diffuser plate communicating with each other, an impeller plate detachably provided inside the diffuser plate, an installation frame fixedly provided inside the diffuser plate, a movable plate slidably provided inside the installation frame, an insert rod fixedly provided on one side of the movable plate, threaded blocks fixedly provided on both sides of the movable plate, a threaded rod rotatably provided inside the installation frame, the threaded blocks being threadedly rotatably disposed on the outer surface of the threaded rod, a movable frame slidably provided inside the installation frame, a handle fixedly provided on one side of the movable frame, the handle slidably disposed inside the installation frame, a toothed plate fixedly provided on the bottom surface of the movable frame, and the outer surface of the threaded rod being fixedly disposed... The diffuser is fitted with a gear, and the gear plate meshes with the gear. First, the diffuser body is installed at the outlet of the centrifugal compressor. When the fluid passes through the diffuser, the flow rate decreases and the pressure increases, thereby realizing energy conversion. When the impeller disk is damaged after long-term use, pulling the handle rod causes it to move the moving frame upward and slide into the mounting frame, which in turn causes the gear plate to rise. The gear plate meshes with the gear, which in turn causes the threaded rod to rotate in the mounting frame. At the same time, the threaded block causes the moving plate to slide in the mounting frame, thereby causing the insertion rod to disengage from the impeller disk, making it easier to disassemble and replace the impeller disk. Then, the new impeller disk is placed into the groove, so that the slot in the impeller disk is flush with the insertion rod. Then, the handle rod is pushed again, causing the moving frame to slide down and the gear plate to descend, which in turn causes the gear to drive the threaded rod to reverse, resetting the moving plate and causing the insertion rod to be inserted into the slot, thereby fixing the impeller disk and facilitating the use of the diffuser body.

[0006] Preferably, the diffuser has a groove, the impeller is installed in the groove, the diffuser has an installation slot, and the installation frame is installed in the installation slot.

[0007] Preferably, the impeller disk has a slot, the insertion rod is movably inserted into the slot, the mounting frame has a through groove, and the handle is slidably disposed in the through groove.

[0008] Preferably, a slider is fixedly provided on the top surface of the movable plate, a groove is provided in the mounting frame, the slider is slidably disposed in the groove, a slide rod is fixedly provided in the groove, and the slider is slidably sleeved on the outer surface of the slide rod.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] By pulling the handle, the moving frame is raised and slid into the mounting frame, causing the threaded rod to rotate within the mounting frame. Simultaneously, the threaded block drives the moving plate to slide within the mounting frame, thus disengaging the insert rod from the impeller disc. This facilitates the disassembly and replacement of the impeller disc, reducing replacement costs by allowing only the impeller disc to be replaced when it is damaged, instead of replacing the entire disc.

[0019] 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.

[0020] Example: Figure 1-6 As shown, this utility model provides a diffuser that is easy to assemble and disassemble, including a diffuser body 1. The diffuser body 1 includes an inlet pipe 11, a mounting plate 12 fixedly mounted at the bottom end of the inlet pipe 11, a positioning groove 121 formed in the mounting plate 12, a diffuser plate 13 fixedly mounted at the top end of the inlet pipe 11, the inlet pipe 11 and the diffuser plate 13 communicating with each other, an impeller plate 14 detachably mounted inside the diffuser plate 13, a mounting frame 2 fixedly mounted inside the diffuser plate 13, a movable plate 21 slidably mounted inside the mounting frame 2, a rod 22 fixedly mounted on one side of the movable plate 21, threaded blocks 23 fixedly mounted on both sides of the movable plate 21, a threaded rod 24 rotatably mounted inside the mounting frame 2, the threaded blocks 23 rotatably mounted on the outer surface of the threaded rod 24, and a movable frame 26 slidably mounted inside the mounting frame 2. A handle 28 is fixedly provided on one side of the movable frame 26. The handle 28 is slidably disposed within the mounting frame 2. A toothed plate 27 is fixedly provided on the bottom surface of the movable frame 26. A gear 25 is fixedly sleeved on the outer surface of the threaded rod 24. The toothed plate 27 meshes with the gear 25. By pulling the handle 28, the movable frame 26 is driven to rise and slide within the mounting frame 2, and the toothed plate 27 is also driven to rise. The toothed plate 27 meshes with the gear 25, thereby causing the threaded rod 24 to rotate within the mounting frame 2. At the same time, the threaded block 23 drives the movable plate 21 to slide within the mounting frame 2, thereby causing the insert rod 22 to disengage from the impeller disk 14. This facilitates the disassembly and replacement of the impeller disk 14. When the impeller disk 14 is damaged, only the impeller disk 14 needs to be replaced, instead of replacing the entire disk, thus reducing replacement costs.

[0021] The diffuser plate 13 has a groove 131 inside, the impeller plate 14 is installed in the groove 131, the diffuser plate 13 has a mounting groove 132 inside, and the mounting frame 2 is installed in the mounting groove 132.

[0022] By adopting the above technical solution, the groove 131 opened in the diffuser 13 facilitates the installation and disassembly of the impeller disk 14, and the mounting groove 132 facilitates the fixing of the mounting frame 2.

[0023] The impeller disk 14 has a slot 141, and the insertion rod 22 is movably inserted into the slot 141. The mounting frame 2 has a through groove 201, and the handle rod 28 is slidably disposed in the through groove 201.

[0024] By adopting the above technical solution, when the moving plate 21 drives the insertion rod 22 to slide in the mounting frame 2, the insertion rod 22 is disengaged from the slot 141, thereby allowing the impeller disk 14 to be removed from the diffuser 13 and replaced. When the moving frame 26 is raised and slid by the hand gripping rod 28, it is placed in the through groove 201, thereby playing an auxiliary sliding role.

[0025] A slider 3 is fixedly provided on the top surface of the movable plate 21. A groove 202 is provided in the mounting frame 2. The slider 3 is slidably disposed in the groove 202. A slide rod 31 is fixedly provided in the groove 202. The slider 3 is slidably sleeved on the outer surface of the slide rod 31.

[0026] By adopting the above technical solution, the sliding rod 31 fixed in the sliding groove 202 causes the moving plate 21 to drive the slider 3 to slide on the outer surface of the sliding rod 31, thereby enabling the moving plate 21 to slide.

[0027] Working principle: First, the diffuser body 1 is installed at the outlet of the centrifugal compressor. When the fluid passes through the diffuser, the flow rate decreases and the pressure increases, thereby achieving energy conversion. When the impeller disk 14 is damaged after long-term use, pulling the handle 28 causes the moving frame 26 to rise and slide within the mounting frame 2, which in turn causes the toothed plate 27 to rise. The toothed plate 27 meshes with the gear 25, causing the threaded rod 24 to rotate within the mounting frame 2. Simultaneously, the threaded block 23 causes the moving plate 21 to slide within the mounting frame 2, thus... The insertion rod 22 is disengaged from the impeller disk 14, making it easier to disassemble and replace the impeller disk 14. Then, the new impeller disk 14 is placed into the groove 131, so that the slot 141 in the impeller disk 14 is flush with the insertion rod 22. Then, the handle 28 is pushed again, causing the moving frame 26 to slide down and the toothed plate 27 to descend. This causes the gear 25 to drive the threaded rod 24 to reverse, so that the moving plate 21 is reset and the insertion rod 22 is inserted into the slot 141, thereby fixing the impeller disk 14 and making it easier to use the diffuser body 1.

The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
