Description
Technical Field
[0001] The utility model relates to the technical field of electromagnetic flowmeters, in particular to an electromagnetic flowmeter which is easy to clean. Background Art
[0002] Electromagnetic flowmeter is a flowmeter that measures flow based on Faraday's law of electromagnetic induction. It is widely used in the measurement of various conductive media. The structure of the electromagnetic flowmeter is mainly composed of a magnetic circuit system, a measuring conduit, electrodes, a casing, a lining and a converter. The measurement principle is based on Faraday's law of electromagnetic induction, that is, when a conductive liquid flows in a non-magnetic electromagnetic flowmeter measuring tube perpendicular to the magnetic field, an induced electromotive force proportional to the flow rate will be generated in a direction perpendicular to the flow direction. The flow rate can be known based on the size of the induced electromotive force.

The cleaning box is provided with a first connecting pipe, and the first connecting pipe is connected to one end of the electromagnetic flowmeter body. The cleaning box is provided with a water pipe, and a water spray pipe is provided between the water pipe and the first connecting pipe.

DETAILED DESCRIPTION
[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0027] like Figure 1 and Figure 2 As shown, an electromagnetic flowmeter which is easy to clean includes a flowmeter body 1, a connecting pipe seat 2 is fixedly installed at the lower end of the flowmeter body 1, an adjusting and cleaning component 3 is fixedly installed at the left position of the top of the outer wall of the connecting pipe seat 2, and a filtering and cleaning component 4 is fixedly installed at the right position of the bottom of the outer wall of the connecting pipe seat 2.
[0028] By adjusting the cleaning assembly 3, the angle and extension size of the flushing pipe 35 can be adjusted to clean the inner wall of the connecting pipe seat 2 in all aspects. At the same time, when the connecting pipe seat 2 enters the sewage, the flushing pipe 35 can be moved upward and rotated to prevent the flushing pipe 35 from accumulating impurities in the sewage. The impurities in the sewage can be intercepted during the flow process by the filtering and cleaning assembly 4. The impurities adhering to the filter plate 41 are subsequently flushed into the material receiving box 43 through the flushing action of the flushing pipe 35, and then discharged through the action of the valve 45, thereby improving the practicality of the electromagnetic flowmeter.
[0029] like Figure 3 and Figure 4 As shown, the adjustment and cleaning assembly 3 includes a mounting plate 31, the lower end of the mounting plate 31 is fixedly installed at the left position of the top of the outer wall of the connecting pipe seat 2, an electric push rod 32 is fixedly installed on the upper left part of the mounting plate 31, a connecting plate 33 is fixedly installed on the output end of the electric push rod 32, and the upper right part of the connecting plate 33 is rotatably connected to a cleaning pipe 34 that passes through the top of the connecting plate 33.
[0030] The output end of the electric push rod 32 drives the connecting plate 33 to move, and the connecting plate 33 can drive the cleaning pipe 34 to move.
[0031] like Figure 4 As shown, the lower end of the cleaning pipe 34 passes through the top of the outer wall of the connecting pipe seat 2, and an L-shaped flushing pipe 35 is fixedly installed on the lower end of the cleaning pipe 34.
[0032] The L-shaped flushing pipe 35 can transport the cleaning liquid to different positions, and can flush and clean different positions of the inner wall of the connecting pipe base 2.
[0033] like Figure 4 and Figure 6As shown, a mounting bracket 36 is fixedly installed in the middle of the upper end of the mounting plate 31, a through hole 37 is opened in the middle of the upper end of the mounting bracket 36, the outer wall of the cleaning tube 34 is movably connected with the inner wall of the through hole 37, an adjusting screw 38 is rotatably connected to the front and rear positions of the upper right end of the mounting bracket 36, a moving block 39 is threadedly connected to the outer wall of the adjusting screw 38, and a rack 310 is fixedly installed on the left side of the moving block 39.
[0034] The cleaning pipe 34 passes through the through hole 37 to move up and down, wherein the adjusting screw 38 is rotated, and the moving block 39 is threadedly connected with the adjusting screw 38 to drive the rack 310 to move.
[0035] like Figure 5 and Figure 6 As shown, a slide groove 311 is opened at the right upper end of the mounting frame 36 , and the slide groove 311 is located on the left side of the adjusting screw 38 . A slider 312 is fixedly installed at the rear lower end of the rack 310 , and the lower end of the slider 312 is slidably connected to the inner wall of the slide groove 311 .
[0036] The moving direction of the rack 310 can be limited by the cooperation between the slider 312 and the slide groove 311 .
[0037] like Figure 5 and Figure 6 As shown, a gear 313 is fixedly sleeved on the top of the outer wall of the cleaning tube 34, and the outer surface of the gear 313 is meshed with the left side of the rack 310. A limiting strip 314 is fixedly installed on the front part of the outer wall of the cleaning tube 34, and a limiting groove 315 is provided on the front part of the inner wall of the gear 313. The front side of the limiting strip 314 is slidably connected to the inner wall of the limiting groove 315.
[0038] The gear 313 drives the cleaning tube 34 to rotate a certain angle by meshing with the rack 310 . At the same time, the cooperation between the limiting strip 314 and the limiting groove 315 can prevent the movement and rotation of the cleaning tube 34 from interfering with each other.

[0040] The filter plate 41 can intercept impurities in the sewage when the sewage passes through the connecting pipe seat 2, and then the impurities adhering to the filter plate 41 can be flushed into the material receiving box 43 from the waste discharge tank 42 through the flushing pipe 35.

[0043] The working principle of the utility model is as follows: when the electromagnetic flowmeter finishes working, no sewage passes through the inner cavity of the connecting pipe seat 2, and the upper end of the cleaning pipe 34 is rotated to connect a hose that can be filled with water, and water and detergent are passed in. Water and detergent are sprayed out from the flushing pipe 35 to flush the inner wall of the connecting pipe seat 2. The electric push rod 32 is started, and the electric push rod 32 drives the connecting plate 33 and the cleaning pipe 34 to move downward to a suitable position, and the adjusting screw 38 is rotated. The moving block 39 drives the rack 310 to move by being threadedly connected with the adjusting screw 38, and the gear 313 drives the cleaning pipe 34 to rotate at different angles by meshing with the rack 310. Among them, when the cleaning pipe 34 moves up and down, the limit bar 314 slides in the limit groove 315. When the cleaning pipe 34 rotates, the gear 313 drives the limit bar 314 through the limit groove 315 to drive the cleaning pipe 34 to rotate, so that the cleaning pipe 34 can move up and down and rotate, so that all directions of the inner wall of the connecting pipe seat 2 can be washed clean, and the dirt washed down will flow out of the connecting pipe seat 2 with the sewage when the electromagnetic flowmeter works next time.
[0044] When the electromagnetic flowmeter is working, the filter plate 41 will intercept large dirt in the sewage. Later, due to the flushing effect of the flushing pipe 35, the adhered dirt will fall into the receiving box 43, and then the staff will open the valve 45 to discharge the impurities and dirt in the receiving box 43 through the waste pipe 44.
[0045] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
