Technical Field

[0001] This utility model relates to the field of flow meter technology, and more specifically, to a high-precision distillation column flow meter. Background Technology

[0002] Flow meters are further classified into differential pressure flow meters, rotor flow meters, throttling flow meters, slit flow meters, volumetric flow meters, electromagnetic flow meters, ultrasonic flow meters, turbine flow meters, and vortex flow meters, among others. They can also be classified by medium: liquid flow meters, gas flow meters, steam flow meters, and solid flow meters. Flow meters are also a crucial component in distillation columns.

[0003] Publication (Announcement) No.: CN222069809U, discloses a convenient water pump flow meter, relating to the technical field of water pump flow meters. This utility model includes a pump body, with a flow meter mounted on the upper end of the pump body. A rotating seat is rotatably mounted on the upper end of the flow meter, with a limit structure between the rotating seat and the flow meter. A mounting bracket, L-shaped, is mounted on the upper end of the rotating seat, and an instrument panel is rotatably mounted on the lower end of the mounting bracket. The surface of the instrument panel has a protective structure, and an adjustment structure is provided on one side of the instrument panel. The rotating seat can rotate on the surface of the flow meter, allowing adjustment of the instrument panel's orientation. The user rotates the handle to turn the adjusting screw. The adjusting sleeve moves along the adjusting screw under the action of the thread, causing one end of a movable support rod to move. The movable support rod then rotates the instrument panel, facilitating angle adjustment and allowing the user to read values ​​from different angles.

[0004] However, with the flow meter disclosed above, impurities still adhere to the pipe wall as water flows, and these impurities cannot be discharged from the main body, causing them to accumulate more and more inside the main body, affecting the measurement effect. Therefore, it is necessary to propose a high-precision distillation column flow meter. Utility Model Content

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.

[0043] like Figure 1-5 As shown, this utility model proposes an embodiment of a high-precision distillation column flow meter, comprising: a flow tube body 1, with two measuring gauges 2 installed on the top of the flow tube body 1. The two measuring gauges 2 can simultaneously measure the flow rate in the flow tube body 1. By comparing with each other, the measurement accuracy is ensured, and the failure to detect damage to the measuring gauges 2 in time is avoided, thus affecting production efficiency.

[0046] The filter screen 5 can move inside the flow tube 1.

[0047] The blade 6 can rotate inside the flow tube 1. When the rotary motor 14 rotates, it drives the blade 6 to rotate, which fully mixes the cleaning liquid fed into the flow tube 1, ensuring that the cleaning liquid can be evenly dispersed on the tube wall of the flow tube 1, thus ensuring the cleaning effect.

[0048] Spacer 7 is fixedly connected inside the flow tube body 1.

[0049] The bidirectional threaded rod 8 can rotate inside the spacer 7. The blade 6 is fixedly connected to the surface of the bidirectional threaded rod 8 and located in the space between the two spacers 7. The filter screen 5 is threadedly connected to the bidirectional threaded rod 8.

[0050] Rotary motor 14 is fixedly connected to the left side of the fixed frame 10, and its output shaft is fixedly connected to the bidirectional threaded rod 8.

[0051] Guide rod 9 is fixedly connected to the spacer 7.

[0052] The fixed frame 10 is fixedly connected to the back of the flow tube 1. The guide rod 9 connects the partition 7 to the fixed frame 10. When too many impurities accumulate in the flow tube 1, the cleaning liquid is sent into the flow tube 1 through the liquid delivery valve 18. The rotary motor 14 drives the filter screen 5 to move back and forth along the direction of the guide rod 9 by continuously rotating forward and backward. The cleaning brush 15 can then complete the reciprocating brushing of impurities on the inner wall of the flow tube 1.

[0053] The sealing cover 11 is sleeved on the surface of the guide rod 9 and the bidirectional threaded rod 8, and can move on the surface of the guide rod 9 and the bidirectional threaded rod 8.

[0054] The push block 12 is fixedly connected to the sealing cover 11.

[0055] The electric push rod 13 fixes the fixed frame 10 to the push block 12. Finally, the electric push rod 13 pushes the sealing cover 11 to separate from the flow tube 1. The cleaning brush 15 discharges the impurities washed off through the ports at both ends of the flow tube 1, avoiding the accumulation of impurities on the inner wall of the flow tube 1 and ensuring measurement accuracy.

[0056] In this embodiment, a cleaning brush 15 is also included. The cleaning brush 15 is installed on the surface of the filter screen 5 and is attached to the inner wall of the flow tube 1 to brush away impurities attached to the inner wall of the flow tube 1, thereby eliminating the possibility of impurities accumulating inside the flow tube 1.

[0057] In this embodiment, a sealing groove 16 is also included, which is formed on both sides of the flow tube body 1.

[0058] The rubber sealing ring 17 is installed on the side of the sealing cover 11 and corresponds to the sealing groove 16. When the sealing cover 11 is closed, the rubber sealing ring 17 will be inserted into the sealing groove 16, which improves the sealing effect of the sealing cover 11 when sealing the flow tube 1.

[0059] In this embodiment, a liquid delivery valve 18 is also included. The liquid delivery valve 18 is connected to the flow pipe 1. The liquid delivery valve 18 is a one-way valve to prevent backflow of the medicine during the cleaning process and to avoid contamination of the medicine.

[0060] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0061] This utility model provides a high-precision distillation column flow meter. When there is too much impurity buildup in the flow tube 1, the cleaning liquid is sent into the flow tube 1 through the liquid delivery valve 18. The rotary motor 14 drives the filter screen 5 to move back and forth along the direction of the guide rod 9 by continuously rotating forward and backward. The cleaning brush 15 can then complete the reciprocating brushing of the impurities on the inner wall of the flow tube 1. The electric push rod 13 pushes the sealing cover 11 to separate from the flow tube 1. The cleaning brush 15 discharges the brushed impurities through the ports at both ends of the flow tube 1.
