Description

Technical Field

[0001] This utility model relates to the technical field of vortex flow meters, and in particular to a vortex flow meter with improved flow range. Background Technology

[0002] With the rapid development of modern industrial technology, the requirements for the accuracy and range of flow measurement are increasing. Vortex flow meters, as a flow measurement instrument based on the principle of fluid oscillation, play an important role in industrial production and scientific research experiments.

[0003] For example, in the existing patent with authorization announcement number CN208109188U, the utility model discloses a vortex flow meter, which relates to the field of metering equipment. When in use, the vortex flow meter can be connected to the pipeline to be measured by screws passing through the mounting flange. The medium to be measured in the pipeline enters the measuring pipe through the mounting flange, the shock-absorbing bellows, and the mounting plate and is measured by the flow meter body. The flow rate of the medium can be measured according to the Karman vortex street principle.

[0004] However, during use, it was found that when conveying larger particles, the flow meter is prone to clogging, which reduces the smoothness of material flow, increases the complexity of maintenance, and reduces the ease of use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a vortex flow meter with an increased range that reduces the blockage caused by excessive material volume within the flow meter body, improves the smoothness of material flow, and enhances ease of use.

[0006] This utility model discloses a vortex flow meter with improved flow range, comprising a flow meter body and a first conveying cylinder, the first conveying cylinder being connected and disposed at the right end of the flow meter body; it also includes a power unit, a discharge device, a feed pipe, multiple sets of first blades and multiple sets of second blades, the feed pipe being connected and disposed on the outer wall of the first conveying cylinder, the power unit being disposed inside the first conveying cylinder, the multiple sets of first blades and multiple sets of second blades being respectively mounted on the power unit, the power unit being used to drive the multiple sets of first blades and multiple sets of second blades to rotate in opposite directions, the multiple sets of first blades and multiple sets of second blades being arranged in cooperation, the discharge device being connected and disposed at the left end of the flow meter body, the discharge device being used to discharge material and dirt; the material is conveyed to the first... Inside the conveying cylinder, the material is then conveyed to the flow meter body via the first conveying cylinder. After flowing through the flow meter body, the material is conveyed to the discharge device, where it is discharged. While the material is being conveyed in the first conveying cylinder, a power device drives multiple sets of first blades to rotate clockwise, and simultaneously drives multiple sets of second blades to rotate counterclockwise. This allows the multiple sets of first and second blades to work together to shear the material, reducing the risk of blockage caused by excessively large material volumes within the flow meter body and improving the smoothness of the material flow through the flow meter body. After the flow meter body is rinsed and cleaned, the rinsing wastewater is discharged through the discharge device, thereby improving the ease of use of the flow meter.

[0007] Preferably, the power unit includes a drive device, a sleeve, a rotating shaft, a support member, a collar, a first bevel gear, and a second bevel gear. The sleeve is rotatably mounted on the right end of the first conveying cylinder. The rotating shaft rotates through the inside of the sleeve, and a bracket is provided inside the first conveying cylinder. The left end of the rotating shaft is rotatably mounted on the bracket. Multiple sets of first blades are circumferentially mounted on the outer wall of the rotating shaft. Multiple sets of support members are circumferentially mounted on the outer wall of the sleeve. Multiple sets of second blades are respectively mounted on the outer walls of the multiple sets of support members. The collar is mounted on the ends of the multiple sets of second blades and rotatably fitted onto the outer wall of the rotating shaft. A bevel gear is mounted on the outer wall of the sleeve, a second bevel gear is mounted on the outer wall of the rotating shaft, and a drive device is mounted on the outer wall of the first conveying cylinder. The drive device is used to drive the first bevel gear and the second bevel gear to rotate in opposite directions. By driving the first bevel gear and the second bevel gear to rotate in opposite directions, the second bevel gear drives the rotating shaft to rotate clockwise, which in turn drives multiple sets of first blades to rotate clockwise. The first bevel gear drives the sleeve to rotate counterclockwise, which in turn drives multiple sets of second blades to rotate counterclockwise, thus improving the convenience of material shearing by multiple sets of first blades and multiple sets of second blades.

[0008] Preferably, the discharge device includes a second conveying cylinder, a first valve, and a second valve. The second conveying cylinder is connected to the left end of the flow meter body, and the first valve is connected to the outer wall of the second conveying cylinder. The material discharged from the flow meter body passes through the second conveying cylinder and is discharged outward, sealing the feed pipe and the opening of the second conveying cylinder. Then, clean water is transported to the inside of the first conveying cylinder through the second valve. After that, the clean water is transported through the first conveying cylinder and the flow meter body to the second conveying cylinder. By opening the first valve, water is discharged through the first valve, improving the convenience of discharging wastewater after rinsing and cleaning the flow meter body and the first conveying cylinder.

[0009] Preferably, the driving device includes a motor and a third bevel gear. The motor is mounted on the outer wall of the first conveying cylinder, and the third bevel gear is mounted on the output end of the motor. The third bevel gear meshes with the first bevel gear and the second bevel gear. The motor drives the third bevel gear to rotate, which in turn drives the first bevel gear and the second bevel gear to rotate in opposite directions.

[0010] Preferably, it also includes blades, which are installed at the end of the rotating shaft; after the rotating shaft rotates, it drives the blades to rotate, so that the blades transport the material in the first conveying cylinder to the inside of the flow meter body, thereby improving the smoothness of material conveying and increasing the material conveying speed.

[0011] Preferably, it also includes a housing, which is installed on the outer wall of the first conveying cylinder and covers the motor, the third bevel gear, the first bevel gear and the second bevel gear; by providing a housing, the convenience of protection is improved.

[0012] Preferably, the inner diameter of the first conveying cylinder is larger than the inner diameter of the flow meter body; by increasing the inner diameter of the first conveying cylinder, the influence of the internal mechanical parts of the first conveying cylinder on the material flow is reduced, thereby improving the smoothness of material conveying.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the material is conveyed into the first conveying cylinder through the feed pipe, and then conveyed into the flow meter body through the first conveying cylinder. After flowing through the flow meter body, the material is conveyed into the discharge device and discharged through the discharge device. When the material is conveyed in the first conveying cylinder, the power device drives multiple sets of first blades to rotate clockwise, and at the same time, the power device drives multiple sets of second blades to rotate counterclockwise. This allows the multiple sets of first blades and multiple sets of second blades to work together to shear the material, reducing the possibility of blockage caused by excessive material volume in the flow meter body and improving the smoothness of material flow through the flow meter body. After the flow meter body is rinsed and cleaned, the rinsing wastewater is discharged out through the discharge device, thereby improving the convenience of using the flow meter.

[0022] like Figure 3As shown, the power unit includes a drive device, a sleeve 6, a rotating shaft 7, a support member 8, a collar 9, a first bevel gear 10, and a second bevel gear 11. The sleeve 6 is rotatably mounted on the right end of the first conveying cylinder 2. The rotating shaft 7 rotates through the inside of the sleeve 6, and a bracket is provided inside the first conveying cylinder 2. The left end of the rotating shaft 7 is rotatably mounted on the bracket. Multiple sets of first blades 4 are circumferentially mounted on the outer wall of the rotating shaft 7. Multiple sets of support members 8 are circumferentially mounted on the outer wall of the sleeve 6. Multiple sets of second blades 5 are respectively mounted on the outer walls of the multiple sets of support members 8. The collar 9 is mounted on the ends of the multiple sets of second blades 5 and is rotatably fitted onto the outer wall of the rotating shaft 7. The first bevel gear 10 is mounted on the outer wall of the sleeve 6, and the second bevel gear 11 is mounted on the outer wall of the rotating shaft 7. The drive device is mounted on the outer wall of the first conveying cylinder 2 and is used to drive the first bevel gear 10 and the second bevel gear 11 to rotate in opposite directions.

[0023] In this embodiment, the material is conveyed into the first conveying cylinder 2 through the feed pipe 3, and then conveyed into the flow meter body 1 through the first conveying cylinder 2. After flowing through the flow meter body 1, the material is conveyed into the discharge device and discharged through the discharge device. When the material is conveyed in the first conveying cylinder 2, the power device drives multiple sets of first blades 4 to rotate clockwise, and at the same time, the power device drives multiple sets of second blades 5 to rotate counterclockwise. This allows the multiple sets of first blades 4 and multiple sets of second blades 5 to work together to shear the material, reducing the possibility of the material being too large and causing blockage in the flow meter body 1, and improving the smoothness of the material flow through the flow meter body 1. After the flow meter body 1 is rinsed and cleaned, the rinsing wastewater is discharged out through the discharge device, thereby improving the convenience of using the flow meter. Example 2

[0024] Based on Example 1, such as Figure 4 As shown, the discharge device includes a second conveying cylinder 12, a first valve 13, and a second valve 14.

The third bevel gear 16 meshes with the first bevel gear 10 and the second bevel gear 11.

[0026] like Figure 3 As shown, it also includes blade 17, which is mounted at the end of the rotating shaft 7;

[0027] like Figure 4As shown, it also includes a housing 18, which is installed on the outer side wall of the first conveying cylinder 2 and covers the motor 15, the third bevel gear 16, the first bevel gear 10 and the second bevel gear 11.

[0029] In this embodiment, the driving device drives the first bevel gear 10 and the second bevel gear 11 to rotate in opposite directions, causing the second bevel gear 11 to drive the rotating shaft 7 to rotate clockwise, which in turn drives the multiple sets of first blades 4 to rotate clockwise. The first bevel gear 10 drives the sleeve 6 to rotate counterclockwise, which in turn drives the multiple sets of second blades 5 to rotate counterclockwise. This improves the convenience of the multiple sets of first blades 4 and multiple sets of second blades 5 in shearing materials. The material discharged from the flow meter body 1 passes through the second conveying cylinder 12 and is then discharged outwards, sealing the openings of the feed pipe 3 and the second conveying cylinder 12. Then, clean water is transported into the first conveying cylinder 2 through the second valve 14. After that, the clean water is transported from the first conveying cylinder 2 and the flow meter body 1 to the second conveying cylinder 12. By opening the first valve 13, the water is discharged through the first valve 13, improving the convenience of discharging the wastewater after rinsing and cleaning the flow meter body 1 and the first conveying cylinder 2.

[0030] This utility model discloses a vortex flow meter with improved flow range. During operation, material is conveyed through the feed pipe 3 into the first conveying cylinder 2, and then through the first conveying cylinder 2 into the flow meter body 1. After flowing through the flow meter body 1, the material is conveyed to the discharge device and discharged. When the material is conveyed in the first conveying cylinder 2, a power device drives multiple sets of first blades 4 to rotate clockwise, and at the same time, the power device drives multiple sets of second blades 5 to rotate counterclockwise. This allows the multiple sets of first blades 4 and multiple sets of second blades 5 to work together to shear the material. After the flow meter body 1 is rinsed and cleaned, the rinsing wastewater is discharged outward through the discharge device.
