Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic flowmeters, and particularly relates to an electromagnetic flowmeter with a flushing and anti-blocking function. Background Art

[0002] ‌An electromagnetic flowmeter‌ is an instrument for measuring the flow rate of conductive liquids based on the principle of electromagnetic induction. It consists of two parts: a sensor and a converter, and mainly works based on Faraday's law of electromagnetic induction. When the conductive measured medium passes through an externally applied magnetic field, an induced electromotive force will be generated in a direction perpendicular to both the medium flow and the magnetic field lines, and this electromotive force is proportional to the velocity of the measured medium moving in the magnetic field.

[0003] However, in the prior art, there are some problems in the use of electromagnetic flowmeters. For example, when the liquid in the pipeline contains a large amount of impurities, these impurities are likely to accumulate on the inner wall of the inner cavity of the measurement pipeline, resulting in more and more impurities accumulating on the inner wall, thus causing blockage and affecting the normal operation and measurement accuracy of the flowmeter.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] Referring to Figures 1-10 , an electromagnetic flowmeter with a flushing and anti-blocking function includes a measuring pipe 1, the measuring pipe 1 is slidably fitted on the top frame of the mounting frame 3, a limiting mechanism 4 is arranged on the front side of one side frame of the mounting frame 3, and a cleaning mechanism 5 is arranged on the rear side of the mounting frame 3 where the limiting mechanism 4 is located. The cleaning mechanism 5 is used to clean the measuring pipe 1, and the cleaning mechanism 5 realizes the flushing and cleaning inside the electromagnetic flowmeter, thereby preventing it from being blocked.

[0019] Among them, the cleaning mechanism 5 includes a cleaning mechanism connecting frame 51. One end of the cleaning mechanism connecting frame 51 is fixedly connected to the mounting frame 3, and an electric cylinder 53 is installed at the bottom of the other end plate body. The output end of the electric cylinder 53 is assembled with a cleaning head 54. The cleaning head 54 is used to clean the inner cavity 16 of the measuring pipe 1. The cleaning head 54 includes a piston rod 541. The piston rod 541 is assembled and connected to the output end of the electric cylinder 53. A plurality of reinforcing rods 542 are fixedly connected in a uniform arrangement at the end of the piston rod 541. The end of the reinforcing rod 542 away from the piston rod 541 is fixedly connected with an annular scraper 543. The annular scraper 543 is used to scrape off the impurities on the inner wall of the inner cavity 16. The annular scraper 543 contacts the inner wall of the inner cavity 16, thereby scraping off the impurities attached to the inner wall of the inner cavity 16.

[0020] In addition, the measuring pipe 1 includes a pipe body 11. A converter assembly 13 is arranged in the middle of the pipe body 11. Connecting flanges 14 are arranged at both ends of the pipe body 11. The connecting flanges 14 are used to connect the connecting pipe 01. An inner cavity 16 is opened inside the pipe body 11. A plurality of limiting bumps 12 are symmetrically arranged on both sides of the outer wall of the pipe body 11 where the converter assembly 13 is located. Semi-circular snap rings 7 are symmetrically installed on both sides of the limiting bumps 12 of the pipe body 11. A plurality of limiting holes 15 are uniformly arranged on the connecting flanges 14. Connecting mechanisms 2 and semi-circular snap ring connecting rods 8 are respectively connected to the two semi-circular snap rings 7. Limiting grooves 71 are arranged on the inner surface of the inner circle of the semi-circular snap rings 7. The limiting grooves 71 cooperate with the limiting bumps 12. The semi-circular snap ring connecting rod 8 is fixedly connected to a pair of semi-circular snap rings 7 on the same side. A second handle plate 9 is vertically fixedly connected to the middle of the semi-circular snap ring connecting rod 8. The second handle plate 9 facilitates the operator to rotate the measuring pipe 1.

[0021] At the same time, a flushing water pipe 52 is arranged on the frame of the cleaning mechanism connecting frame 51. The output end at the bottom of the flushing water pipe 52 is used to flush the inner cavity 16. The flushing water pipe 52 is used to spray water into the inner cavity 16 through a water pump for cleaning.

[0022] Moreover, a slide rail 31 is provided on the bottom surface of the top frame of the mounting frame 3. A connecting mechanism 2 is slidably engaged with the slide rail 31. One end of the slide rail 31 is symmetrically provided with limiting rods 32. A placement platform 33 is provided at the bottom of the frame of the mounting frame 3. A collection box 6 is horizontally placed on the upper surface of the placement platform 33. The collection box 6 is located below the cleaning mechanism 5. The connecting mechanism 2 includes a slider 22. The slider 22 is slidably engaged with the slide rail 31. A first handle plate 221 is fixedly connected to the slider 22. A rotating seat 23 is installed at the bottom of the slider 22. A connecting frame 21 is rotatably arranged on the rotating seat 23. The rotating seat 23 enables the measuring pipe 1 to tilt and rotate.

[0023] Meanwhile, the connecting frame 21 includes a rotating head 211. The rotating head 211 is rotatably engaged with the rotating seat 23. Two connecting rods 212 are symmetrically and fixedly connected to the bottom of the rotating head 211. A semi-circular clamping ring 7 is fixedly connected to the bottom of the connecting rods 212. The semi-circular clamping ring 7 is used for connecting the measuring pipe 1.

[0024] In addition, the limiting mechanism 4 includes a limiting mechanism connecting frame 41. One end of the limiting mechanism connecting frame 41 is connected to the mounting frame 3. Two telescopic connecting rods 42 are symmetrically arranged on the other end plate body. One end of the movable rod body of the telescopic connecting rod 42 is fixedly connected to a support plate 43. Two limiting columns 45 are symmetrically arranged on the support plate 43. The limiting columns 45 are adapted to the limiting holes 15. A spring 44 is sleeved outside the telescopic connecting rod 42. One end of the spring 44 is connected to the limiting mechanism connecting frame 41, and the other end is connected to the support plate 43. The support plate 43 is used to support the measuring pipe 1.

[0025] In this embodiment, in order to prevent a large amount of impurities from accumulating in the inner cavity 16 of the measuring pipe 1 and causing blockage, the electromagnetic flowmeter is regularly flushed and cleaned. After the equipment is shut down, the connection between the measuring pipe 1 and the connecting pipes 01 on both sides is disconnected. At this time, the operator pushes the slider 22 to slide on the slide rail 31 through the first handle plate 221. When approaching the limiting mechanism 4, the operator rotates the measuring pipe 1 through the second handle plate 221 and presses down the support plate 43, so that the telescopic connecting rod 42 contracts. The tilted measuring pipe 1 after rotation is placed on the support plate 43, and the support plate 43 is released. The spring 44 releases elastic potential energy, driving the limiting column 45 to reset, and the limiting column 45 is clamped into the limiting hole 15 to fix the position of the measuring pipe 1.

[0026] After the position of the measuring pipe 1 is fixed, the electric cylinder 53 is activated at this time, and the flushing water pipe 52 sprays water into the inner cavity 16 for flushing. As the electric cylinder 53 works and drives the piston rod 541 to slowly extend, the annular scraper 543 will quickly scrape off the impurities attached to the inner wall of the inner cavity 16. At the same time, the water sprayed by the flushing water pipe 52 flushes the scraped impurities down. And the tilted measuring pipe 1 facilitates the water to carry the impurities and flow into the collection box 6 below.

[0027] In the present invention, the connection mechanism 2 cooperates with the mounting frame 3 to achieve the switching of the position of the measuring pipeline 1. The provided limiting mechanism 4 can effectively maintain the inclined state of the measuring pipeline 1. For the provided cleaning mechanism 5, when the electric cylinder 53 operates to drive the piston rod 541 to slowly extend, the annular scraper 543 will quickly scrape off the impurities adhering to the inner wall of the inner cavity 16. At the same time, the water sprayed by the flushing water pipe 52 is used to wash down the scraped impurities. Moreover, the inclined measuring pipeline 1 facilitates the water to carry the impurities and flow into the lower collecting box 6, so as to achieve the rapid cleaning of the impurities inside the electromagnetic flowmeter and effectively prevent the impurities on the inner wall of the inner cavity 16 from causing the blockage of the electromagnetic flowmeter.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
