Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vortex flow meter technology, specifically a high-temperature resistant vortex flow meter. Background Technology
[0002] A vortex flow meter is a volumetric flow meter researched and manufactured based on the Karman vortex street principle to measure the volumetric flow rate, standard volumetric flow rate, or mass flow rate of gases, steam, or liquids. It is mainly used for flow measurement of fluids in industrial pipelines, such as gases, liquids, and steam.
[0003] In the existing technology, excessively high temperatures of electronic components in electronic instruments can affect their working accuracy and shorten their service life. Flow meters inevitably come into contact with high-temperature liquids during use, and heat will enter the electronic instrument through the support tube, exacerbating its temperature rise and thus affecting the use of the electronic instrument. Summary of the Invention
[0004] The purpose of this invention is to provide a high-temperature vortex flow meter that allows electronic instruments to operate continuously at lower temperatures, thus extending the service life of this invention.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-temperature vortex flow meter is provided, comprising a measuring tube and an electronic instrument. A support tube is fixedly connected between the measuring tube and the electronic instrument. A temperature-conducting tube and a support plate are respectively connected to the outer wall of the support tube. A circular plate is fixedly connected to the outer wall of the temperature-conducting tube. A water tank and a water pump are respectively fixedly connected to one side of the upper end face of the support plate. A guide pipe is fixedly connected to the outlet end of the water pump. An atomizing nozzle is fixedly connected to the outer wall of the guide pipe.
[0006] Optionally, the temperature-conducting tube is rotatably connected to the outer wall of the support tube, and the inner wall of the temperature-conducting tube is slidably fitted against the outer wall of the support tube. The temperature-conducting tube is made of copper.
[0007] Optionally, a water supply pipe is fixedly connected to one side of the upper end face of the water tank, and the water outlet of the water tank and the water inlet of the water pump are fixedly connected by a pipe.
[0008] Optionally, the atomizing nozzle is positioned toward the center of the disc, and multiple discs and atomizing nozzles are provided, with the multiple discs and multiple atomizing nozzles being arranged alternately.
[0009] Optionally, heat sinks are fixedly connected to both the front and rear outer walls of the measuring tube, and the heat sinks are made of copper sheets.
[0010] Optionally, a motor is fixedly connected to the upper surface of the support plate away from the water tank, a gear is fixedly connected to the output end of the motor, and a gear ring is fixedly connected to the outer wall of the temperature-conducting pipe, with the gear meshing with the gear ring.
[0011] Optionally, the gear ring is positioned above the circular plate, and the radius of the gear ring is larger than the radius of the gear.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. This utility model utilizes the cooperation of a temperature-conducting pipe, a circular plate, a support plate, a water tank, a water pump, a flow guide pipe, and an atomizing nozzle. When the high-temperature liquid flows through the measuring tube, it can effectively dissipate heat through the temperature-conducting pipe and the circular plate. At the same time, the water pump draws the liquid from the water tank into the flow guide pipe, and then sprays it onto the circular plate from the atomizing nozzle, which can further improve the heat dissipation effect and prevent the heat of the high-temperature liquid from being conducted to the electronic instrument in large quantities through the support pipe, thus affecting the measurement accuracy of the electronic instrument.
[0014] 2. This utility model, through the cooperation of the gear ring, motor and gear, can further drive the gear to rotate through the motor, which in turn drives the gear ring to rotate, and then drives the disc to rotate through the heat conduction pipe, so that the atomized liquid sprayed by the atomizing nozzle can be more evenly distributed on the surface of the disc, further improving its heat dissipation effect.

[0025] Reference Figure 1-4The present invention provides a high-temperature vortex flow meter according to an embodiment of the present invention. A high-temperature vortex flow meter includes a measuring tube 1 and an electronic instrument 3. A support tube 2 is fixedly connected between the measuring tube 1 and the electronic instrument 3. A temperature-conducting tube 4 and a support plate 7 are respectively connected to the outer wall of the support tube 2. A circular plate 6 is fixedly connected to the outer wall of the temperature-conducting tube 4. A water tank 10 and a water pump 12 are respectively fixedly connected to one side of the upper end face of the support plate 7. A guide pipe 13 is fixedly connected to the outlet end of the water pump 12. An atomizing nozzle 14 is fixedly connected to the outer wall of the guide pipe 13. Heat is dissipated through the temperature-conducting tube 4 and the circular plate 6. The water pump 12 pumps the liquid in the water tank 10 into the guide pipe 13, and then sprays it onto the circular plate 6 from the atomizing nozzle 14, further improving the heat dissipation effect.
[0026] The present invention provides a high-temperature vortex flow meter. Compared with the prior art, the cooperation of the heat-conducting pipe 4, the disc 6, the support plate 7, the water tank 10, the water pump 12, the guide pipe 13 and the atomizing nozzle 14 helps to prevent the heat of the high-temperature liquid from being conducted to the electronic instrument 3 in large quantities through the support pipe 2, thus affecting the measurement accuracy of the electronic instrument 3.
[0027] In another embodiment of this utility model, please refer to Figure 2 and Figure 3 The temperature-conducting pipe 4 is rotatably connected to the outer wall of the support pipe 2, and the inner wall of the temperature-conducting pipe 4 is slidably attached to the outer wall of the support pipe 2. The temperature-conducting pipe 4 is made of copper metal to improve its thermal conductivity. A water supply pipe 11 is fixedly connected to one side of the upper end face of the water tank 10. The outlet of the water tank 10 and the inlet of the water pump 12 are fixedly connected by a pipe. The water pump 12 pumps the liquid in the water tank 10 out and flows. The atomizing nozzle 14 is set towards the center of the disc 6. There are multiple discs 6 and multiple atomizing nozzles 14. The multiple discs 6 and multiple atomizing nozzles 14 are staggered to ensure that each disc 6 is within the spray range of the atomizing nozzle 14.
[0028] In another embodiment of this utility model, please refer to Figure 1 and Figure 2 Heat sinks 15 are fixedly connected to the front and rear outer walls of the measuring tube 1. The heat sinks 15 are made of copper sheets and are used to dissipate heat from the high-temperature liquid flowing through the measuring tube 1.
[0029] In another embodiment of this utility model, please refer to Figures 1 to 3A motor 8 is fixedly connected to the upper surface of the support plate 7 away from the water tank 10. A gear 9 is fixedly connected to the output end of the motor 8. A gear ring 5 is fixedly connected to the outer wall of the temperature-conducting pipe 4. The gear 9 meshes with the gear ring 5. The motor 8 drives the gear 9 to rotate, thereby driving the gear ring 5 to rotate. In turn, the temperature-conducting pipe 4 drives the disc 6 to rotate relative to the atomizing nozzle 14. This ensures that the liquid sprayed from the atomizing nozzle 14 contacts the disc 6 more evenly. The gear ring 5 is positioned above the disc 6. The radius of the gear ring 5 is larger than the radius of the gear 9 to prevent the gear ring 5 from rotating too fast and to improve the stability of the disc 6 during rotation, thereby ensuring that the disc 6 can fully contact the liquid.
