Description

Technical Field

[0001] This utility model relates to the field of centrifugal compressor technology, and more specifically to a volute device. Background Technology

[0002] The volute mechanism is widely used in various fields, and its technology is based on Bernoulli's principle and the continuity equation. The volute collects the fluid flowing out of the impeller outlet and converts the fluid's kinetic energy into pressure energy before delivering it to the outlet, thus reducing speed, increasing pressure, and minimizing hydraulic losses. In hydropower generation, air conditioning systems, and engines, the volute is a key component, converting the kinetic energy of a high-speed rotating liquid into pressure energy to drive the efficient operation of related equipment.

[0003] It mainly consists of a spiral or annular chamber that gradually expands to accommodate the velocity changes of the fluid flowing out of the high-speed rotating impeller. The inlet of the volute is tightly connected to the outlet of the impeller, ensuring smooth fluid entry.

[0004] Although the existing device has many beneficial effects, it still has the following problems: the device may lack quick-disassembly components during use, making it impossible to disassemble quickly, which affects the rapid installation and subsequent maintenance of the centrifugal compressor; secondly, the sealing effect may not be good enough, which may cause fluid leakage in the volute and increase energy consumption. Therefore, it needs to be improved. In view of this, we propose a volute device. Utility Model Content

[0035] in;

[0036] The fixing component 100 includes a top housing 110, a bottom housing 120 is provided at the bottom of the top housing 110, a first locking block 150 is tightly welded to both sides of the bottom housing 120, and a second locking block 160 is tightly welded to both sides of the top housing 110.

[0037] The volute assembly 200 includes a volute housing 210 disposed on the top of the bottom housing 120, a fixing ring 220 tightly welded to the air outlet of the volute housing 210, a base 230 sleeved on the bottom of the volute housing 210, an impeller 240 rotatably connected to the top of the base 230, and a fixing ring 250 bolted to the top of the base 230.

[0038] The sealing assembly 300 includes a clamp 310 disposed in the inner cavity of the fixing ring 220, the inner wall of the clamp 310 is tightly welded to the fixing ring 320, and a rubber ring 340 is sleeved on the inner circumference of the fixing ring 320.

[0039] The quick bolt 400 includes a head plate 410 disposed on both sides of the top housing 110. A screw 430 is tightly welded to the bottom of the head plate 410. A spring 460 is sleeved on the outer circumference of the screw 430. A fixing barrel 470 is sleeved on the outer circumference of the screw 430. A base plate 480 is tightly welded to the bottom of the fixing barrel 470.

[0040] Meanwhile, in order to make it easier for the top housing 110 and the bottom housing 120 to snap together, specifically, the top of the bottom housing 120 is provided with a plurality of fixing posts 130, and the top of the bottom housing 120 is provided with a groove 140, the size of which matches the volute assembly 200.

[0041] Furthermore, for better performance of the top outer shell 110 and the bottom outer shell 120, specifically, the top of the second locking block 160 is rotatably connected to an iron ring, and the first locking block 150 has a groove that matches the iron ring.

[0042] It is worth noting that, in order to facilitate the snap-fit ​​sealing assembly 300, specifically, the outer circumferential wall of the clamp 310 is tightly welded with a ring array of multiple fixing blocks 330, and the ring formed by the multiple fixing blocks 330 matches the size of the inner cavity of the fixing ring 220.

[0043] It is worth noting that, in order to facilitate the replacement of the sealing component 300, specifically, protruding rings are tightly welded on both sides of the clamp 310, and rubber sleeves 350 and 360 are respectively fixed on both sides of the rubber ring 340. Protruding rings are fixed on the sides of rubber sleeves 350 and 360, and the size of protruding rings matches the protruding rings 1 on both sides of the clamp 310.

[0044] In some embodiments, rubber sleeve 350, rubber ring 340, and rubber sleeve 360 ​​are manufactured using an integral casting process, and they all use polyurethane rubber. Polyurethane rubber has excellent wear resistance, high pressure resistance, and aging resistance, while also possessing good elasticity, meeting the material flexibility requirements of the integral casting process. Furthermore, polyurethane rubber also has excellent oil resistance, making it suitable for various industrial environments.

[0045] The fixing blocks 330 arranged in a ring on the outer circumference of the clamp 310 engage with the inner cavity of the fixing ring 220. The fixing ring 320 on the inner circumference of the clamp 310 is for easy installation of the rubber parts consisting of rubber sleeve 350, rubber ring 340, and rubber sleeve 360. The rubber sleeve 350, rubber ring 340, and rubber sleeve 360 ​​are integrally formed. The protruding rings 2 on the sides of the rubber sleeve 350 and rubber sleeve 360 ​​engage with the protruding ring 1 on the side of the clamp 310. The diameter of the protruding ring 2 is smaller than that of the protruding ring 1, and they can be interlocked. Thus, when the rubber ring 340 is interlocked with the fixing ring 320 on the inner circumference of the clamp 310, the rubber sleeve 350 and rubber sleeve 360 ​​are also interlocked with the clamp 310, thus completing the installation of the rubber parts. As the rubber parts age over time, they can be disassembled and replaced with new ones.

[0046] Next, quick bolts 400 are used for easy rotation. Specifically, multiple protruding blocks 420 are tightly welded to the top of the head plate 410 in a ring array. A top cover 450 is provided at the bottom of the head plate 410. Anti-slip textures are provided on both sides of the protruding blocks 420.

[0047] Subsequently, to prevent the spring 460 from moving arbitrarily, a limiting ring 440 is tightly welded to the outer circumference of the screw 430, and the limiting ring 440 matches the size of the fixing barrel 470. When the volute assembly 200 needs to be fixed, it is first placed on top of the bottom outer shell 120, and simultaneously, multiple fixing posts 130 on the top of the bottom outer shell 120 interlock with the bottom of the top outer shell 110. Then, the iron ring on the second locking block 160 is rotated to fix it in the groove at the bottom of the first locking block 150, thus fixing the volute assembly 200. Finally, the fixing assembly 100 is used to... The quick bolt 400 is used to fix the fastening assembly 100. By pressing down and rotating the protruding block 420, the head plate 410 and the screw 430 are also pressed down and rotated. The limiting ring 440 on the outer circumference of the screw 430 presses down the spring 460. The fixing barrel 470 restricts the position of the spring 460. The fixing barrel 470 is welded to the top cover 450 and the bottom plate 480 to form a sealed environment, which ensures that the spring 460 is not affected by the external environment, thus extending the service life of the quick bolt 400. The quick bolt 400 facilitates the quick assembly and disassembly of the fastening assembly 100.

[0048] Working principle:

[0049] When this device is in operation, firstly, the volute assembly is fixed by the fixing component 100. The volute assembly 200 is installed on top of the bottom outer shell 120. The top outer shell 110 and the bottom outer shell 120 are securely connected by a locking block 150 and a locking block 260 via an iron ring, ensuring the initial fixation of the device. Secondly, the quick bolt 400 is pressed down and rotated by the protruding block 420 on the head plate 410 and tightened by the screw 430 in the fixing barrel 470 via the spring 460. At the same time, the limiting ring 440 ensures that the spring 460 does not move randomly. When disassembly is required, simply unscrew the protruding block 420, and the force stored in the spring 460 will cause the screw 430 to return to its original position, achieving the purpose of quick disassembly. Next, the impeller 240 inside the volute outer shell 210 starts to work, generating airflow, which is discharged through the fixing ring 220 at the air outlet of the volute outer shell 210. To ensure airflow tightness and prevent leakage, the sealing assembly 300 is disposed within the inner cavity of the fixing ring 220. The clamp 310 is tightly engaged with the fixing ring 220 via the fixing block 330. Simultaneously, the rubber ring 340 is sealed to the clamp 310 via the rubber sleeve 350 and the rubber sleeve 360, ensuring the airtightness of the device. This completes the fixation and sealing of the entire volute assembly.
