Description

Technical Field

[0001] This utility model relates to the field of vortex flow meters, and more particularly to a vortex flow meter. Background Technology

[0002] The vortex flow meter adopts advanced microprocessor technology and has the advantages of powerful functions, wide flow range, simple operation and maintenance, and convenient installation and use. Its working principle is as follows: when the fluid passes through the vortex generator composed of helical blades, the fluid is forced to rotate violently around the generator axis to form a vortex. When the fluid enters the diffuser section, the vortex flow is subjected to the backflow effect and begins to rotate a second time, forming a gyroscopic vortex precession phenomenon. The precession frequency is proportional to the flow rate and is not affected by the physical properties and density of the fluid. The detection element measures the precession frequency of the fluid's second rotation.

[0003] The patent application with publication number CN223091333U in the prior art uses a combination of a cylindrical body and a defoaming component to filter the medium flowing into the pipe. The filtered medium is then defoamed by spiral blades and defoaming needles, which reduces the impact of air bubbles in the medium on the measurement results of the vortex flowmeter and has good practicality.

[0004] The cylinder can be fixedly installed inside the pipe by the fixed components. At the same time, pulling the pull block outward will cause the pull block to move the slide plate outward, which will stretch the spring. Meanwhile, the connecting rod will cause the limit block and the limit to disengage from the limit groove and the limit hole, so that the cylinder is separated from the pipe, making it convenient to clean and replace the cylinder.

[0005] However, current swirl flow meters use a rotating shaft with helical blades to defoam the foamy liquid as it flows into the meter. However, the small volume of foamy liquid flowing into the swirl flow meter can not drive the rotating shaft and thus fail to eliminate the foam.

[0006] Therefore, it is necessary to provide a vortex flow meter to solve the above-mentioned technical problems. Utility Model Content

[0007] This invention provides a swirl flow meter that solves the problem that when foam flows into the swirl flow meter, the flow rate is too low, which prevents the drive of the rotating shaft with spiral blades and thus fails to eliminate the foam in the liquid.

[0008] To solve the above-mentioned technical problems, this utility model provides a vortex flow meter, comprising: The flow meter body, disassembly sleeve, two filter assemblies, rotating parts, and multiple dispersion blocks; The disassembly sleeve is threadedly connected to one end of the flow meter body; The two filter components are symmetrically arranged at one end of the disassembly sleeve; The rotating component is located at one end of the disassembly sleeve; The plurality of the dispersed blocks are respectively connected to the inner wall of the flow meter body.

[0009] Preferably, the filter assembly includes a filter screen, a mounting plate, and bolts, with the filter screen disposed at one end of the disassembly sleeve and the mounting plate mounted on the surface of the filter screen.

[0010] Preferably, the bolt is disposed between the mounting plate and the disassembly sleeve.

[0011] Preferably, the disassembly sleeve has a rotating blade inside and is connected to one end of the rotating component via a connecting block.

[0012] Preferably, the rotating component and the plurality of dispersion blocks are used for the elimination of liquid foam.

[0013] Preferably, a connecting component is provided on the plurality of the dispersed blocks. The connecting component includes a connecting ring, two mounting blocks and two threaded bolts. The connecting ring is disposed inside the flow meter body, and the two mounting blocks are symmetrically mounted inside the connecting ring.

[0014] Preferably, the two threaded bolts are respectively disposed between the two mounting blocks and the disassembly sleeve.

[0015] Compared with related technologies, the swirl flowmeter provided by this utility model has the following beneficial effects: This utility model provides a vortex flow meter, in which a disassembly sleeve with two filter components and a rotating part is set inside the flow meter body, which works in conjunction with multiple dispersion blocks. This facilitates the elimination of foam on the liquid after a small flow of foamy liquid flows into the flow meter body, with the help of the rotating part and multiple dispersion blocks.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] First Embodiment Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 This is a schematic diagram of the structure of a first embodiment of a vortex flowmeter provided by this utility model; Figure 2 for Figure 1 The diagram shows a three-dimensional structure of the vortex flowmeter from a first-view perspective. Figure 3 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 1 The diagram shows a three-dimensional structural representation of the vortex flowmeter from a second perspective. A vortex flowmeter includes: The flow meter body 1, disassembly sleeve 2, two filter components 3, rotating parts 4, and multiple dispersion blocks 6; The disassembly sleeve 2 is threadedly connected to one end of the flow meter body 1; The two filter components 3 are symmetrically arranged at one end of the disassembly sleeve 2; The rotating component 4 is disposed at one end of the disassembly sleeve 2; Multiple of the dispersed blocks 6 are respectively connected to the inner wall of the flow meter body 1.

[0020] The filter assembly 3 includes a filter screen 31, a mounting plate 32, and bolts 33. The filter screen 31 is disposed at one end of the disassembly sleeve 2, and the mounting plate 32 is mounted on the surface of the filter screen 31.

[0021] The bolt 33 is disposed between the mounting plate 32 and the disassembly sleeve 2.

[0022] The disassembly sleeve 2 has a rotating blade 5 inside and is connected to one end of the rotating component 4 via a connecting block.

[0023] The rotating component 4 and the plurality of dispersing blocks 6 are used to eliminate liquid foam.

[0024] The filter screen 31 is made of stainless steel, which can effectively intercept impurities without excessively hindering the flow of small-flow liquids; the mating surfaces of the mounting plate 32 and the disassembly sleeve 2 are equipped with rubber sealing rings to prevent unfiltered liquid from flowing in directly and improve filtration reliability.

[0025] The rotating blade 5 is made of lightweight engineering plastic; the rotating part 4 has spiral ridges on its surface, which improves the shearing efficiency of foam when rotating and solves the problem that the traditional spiral blade shaft cannot be driven under low flow conditions.

[0026] Multiple dispersion blocks 6 are arranged in a ring array on the inner wall of the flow meter body 1. Each dispersion block 6 is a triangular prism structure with rounded corners on the edges facing the liquid flow direction, which enhances the foam collision and breaking effect and reduces the resistance to liquid flow, thus ensuring measurement accuracy.

[0027] The threaded connection between the disassembly sleeve 2 and the flow meter body 1 uses fine threads and is equipped with PTFE sealing tape, which ensures both sealing performance and easy manual disassembly without the need for special tools, making it suitable for quick on-site maintenance.

[0028] If the filter screen 31 or the rotating blade 5 needs to be cleaned, the disassembly sleeve 2 can be rotated to remove it, and the bolt 33 can be unscrewed to separate the mounting plate 32 from the filter screen 31. The filter screen 31 can then be cleaned or replaced. At the same time, the rotating blade 5 and rotating parts 4 inside the disassembly sleeve 2 can be cleaned directly.

[0029] The working principle of the vortex flowmeter provided by this utility model is as follows: In use, the foamy liquid flows in from the inlet of the flow meter body 1 and first passes through two filter components 3 at one end of the disassembly sleeve 2. The filter screen 31 filters impurities in the liquid to prevent them from entering the flow meter and affecting the measurement accuracy. The mounting plate 32 fixes the filter screen 31 to the disassembly sleeve 2 with bolts 33 to ensure a stable filtration process.

[0030] The filtered liquid enters the disassembly sleeve 2, impacting the rotating blade 5 and causing the rotating component 4 to rotate. Even when the liquid flow rate is low, the rotating blade 5 can still drive the rotating component 4 to rotate at a low speed under the impact force of the liquid, preparing for subsequent defoaming. When the rotating part 4 rotates, it generates a shearing effect on the foam in the liquid, initially breaking the foam; at the same time, the liquid carrying the unbroken foam continues to flow into the interior of the flow meter body 1, colliding with multiple dispersion blocks 6 on the inner wall.

[0031] The irregular distribution of the dispersion blocks 6 alters the liquid flow path, further breaking up the foam through collisions and turbulence, thus achieving a defoaming effect. The foam-free liquid then forms a stable vortex through the vortex generator in the flow meter body 1, completing the flow measurement.

[0032] Compared with related technologies, the swirl flowmeter provided by this utility model has the following beneficial effects: This utility model provides a vortex flow meter, in which a disassembly sleeve 2 with two filter components 3 and a rotating component 4 is set inside the flow meter body 1, which works in conjunction with multiple dispersion blocks 6. This allows the foam on the liquid to be eliminated with the help of the rotating component 4 and multiple dispersion blocks 6 after a small flow of foamy liquid flows into the flow meter body 1.

[0033] Second Embodiment Please refer to the following: Figure 5 and Figure 6 Based on the swirl flow meter provided in the first embodiment of this application, the second embodiment of this application proposes another swirl flow meter. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0034] Specifically, the second embodiment of this application provides a swirl flow meter that differs in that it further includes a connecting component 7, which is disposed on a plurality of the dispersed blocks 6. The connecting component 7 includes a connecting ring 71, two mounting blocks 72 and two threaded bolts 73. The connecting ring 71 is disposed inside the flow meter body 1, and the two mounting blocks 72 are symmetrically mounted inside the connecting ring 71.

[0035] The two threaded bolts 73 are respectively disposed between the two mounting blocks 72 and the disassembly sleeve 2.

[0036] The ends of multiple dispersed blocks 6 are welded or bonded to the inner wall of the connecting ring 71, and two mounting blocks 72 are symmetrically welded to the outer side of the connecting ring 71 to form an integral assembly.

[0037] Place the assembled connecting ring 71 inside the flow meter body 1, adjust its position so that the mounting block 72 is aligned with the corresponding position of the disassembly sleeve 2, and fix the connecting ring 71 inside the flow meter body 1 by passing two threaded bolts 73 through the mounting block 72 and screwing them into the threaded holes of the disassembly sleeve 2.

[0038] After the liquid undergoes initial defoaming by the rotating part 4, it flows into the body of the flow meter 1 and collides with multiple dispersion blocks 6 on the connecting ring 71. The connecting ring 71 ensures that the dispersion blocks 6 are fixed in position, preventing the dispersion blocks from shifting due to liquid impact and ensuring stable defoaming effect.

[0039] When the dispersing block 6 needs to be cleaned or replaced, first unscrew the disassembly sleeve 2, then unscrew the two threaded bolts 73, and remove the connecting ring 71 from the flow meter body 1 as a whole, so as to thoroughly clean the foam residue on the surface of the dispersing block 6.

[0040] After maintenance, reverse the steps to reset and fix the connecting ring 71, and then reinstall and remove the sleeve 2.

[0041] The threaded holes on the mounting block 72 and the corresponding holes on the disassembly sleeve 2 are aligned with each other using a locating pin, eliminating the need for repeated position adjustments during installation.

[0042] The inner diameter of the connecting ring 71 can be customized according to the specifications of the flow meter body 1. The dispersion block 6 can be detachably connected to the connecting ring 71 by bolts, replacing the original welding or bonding method. This makes it easy to replace dispersion blocks of different shapes according to the characteristics of liquid foam, thus improving the versatility of the device.

[0043] Compared with related technologies, the swirl flowmeter provided by this utility model has the following beneficial effects: This utility model provides a swivel flow meter, in which a connecting ring 71, two mounting blocks 72 and two threaded bolts 73 are provided inside the flow meter body 1 to facilitate the overall installation of multiple dispersion blocks 6, and also to facilitate the later installation and disassembly of the multiple dispersion blocks 6 inside the flow meter body 1 for cleaning of the dispersion blocks 6.

[0044] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
