[0002] Electromagnetic flowmeter is an instrument for measuring the volume flow of conductive liquids. Its basic principle is to use Faraday's law of electromagnetic induction, that is, when a conductor cuts magnetic lines of force in a magnetic field, an induced electromotive force is generated at both ends of the conductor. Electromagnetic flowmeters are widely used. During use, because the water contains impurities or silt, when water passes through the electromagnetic flowmeter, impurities or silt are easily accumulated in the electromagnetic flowmeter, causing the electromagnetic flowmeter to be blocked, affecting the measurement effect and measurement accuracy of the electromagnetic flowmeter.

[0007] Furthermore, the mounting seat is communicated with the interior of the liquid inlet pipe, and a filter screen cylinder is installed at a relatively inner end of the detachable base, and the outer diameter of the filter screen cylinder is equal to the inner diameter of the liquid inlet pipe.

[0008] Furthermore, the electromagnetic flowmeter body is installed on the outer side of the liquid outlet pipe and its measuring end is located inside the liquid outlet pipe.

[0020] See also Figure 1-Figure 5 The utility model provides a technical solution: an anti-clogging electromagnetic flowmeter, comprising an inlet pipe 1, an outlet pipe 2, a connecting flange 3, an electromagnetic flowmeter body 4, a mounting seat 5, a first threaded groove 6, a detachable base 7, a second threaded groove 8 and a driving motor 9. The outlet pipe 2 is welded on the right side of the inlet pipe 1 and the inlet pipe 1 and the outlet pipe 2 are interconnected in a V shape. The ends of the inlet pipe 1 and the outlet pipe 2 are both provided with connecting flanges 3. The electromagnetic flowmeter body 4 is arranged on the right side of the inlet pipe 1. A mounting seat 5 is welded on the lower end of the inlet pipe 1. The inner wall of the mounting seat 5 is provided with a first threaded groove 6. A detachable base 7 is arranged inside the mounting seat 5. The outer side of the detachable base 7 is provided with a second threaded groove 8. A driving motor 9 is installed at the bottom of the detachable base 7. This design solves the problem that the original anti-clogging electromagnetic flowmeter is not simple and convenient to use.

[0021] As the first embodiment of the utility model: the detachable base 7 is engaged with the inside of the mounting seat 5, the first thread groove 6 and the second thread groove 8 are meshed with each other, the first thread groove 6 and the second thread groove 8 can fix the position between the detachable base 7 and the mounting seat 5, and a rotating handle 71 is installed at the relatively outer end of the detachable base 7. The rotating handle 71 is convenient for the user to rotate the detachable base 7. A sealing gasket 51 is bonded to the bottom of the mounting seat 5. The sealing gasket 51 can enhance the sealing of the connection between the detachable base 7 and the mounting seat 5. The mounting seat 5 is connected to the inside of the liquid inlet pipe 1, and a filter screen cylinder 91 is installed at the relatively inner end of the detachable base 7. The outer diameter of the filter screen cylinder 91 is equal to the inner diameter of the liquid inlet pipe 1. The filter screen cylinder 91 can filter the liquid in the liquid inlet pipe 1 Impurities and debris are prevented from entering the liquid outlet pipe 2 and causing blockage. The electromagnetic flowmeter body 4 is installed on the outer side of the liquid outlet pipe 2 and its measuring end is located inside the liquid outlet pipe 2. The electromagnetic flowmeter is used to monitor the flow situation inside the liquid outlet pipe 2. An airtight connector 94 is arranged inside the detachable base 7. A rotating shaft 92 is arranged inside the airtight connector 94. The airtight connector 94 can reduce the friction during rotation without affecting the sealing performance of the connection between the rotating shaft 92 and the detachable base 7. Several groups of cutting blades 93 are arranged on the outer side of the rotating shaft 92 with equal specifications. The end of the rotating shaft 92 is connected to the output end of the driving motor 9. The driving motor 9 can drive the rotating shaft 92 to rotate, and the rotating shaft 92 can drive the cutting blade 93 to rotate to cut the blockage.

[0022] As a second embodiment of the present utility model: after the liquid to be measured enters the liquid inlet pipe 1, the impurities and debris inside it will be retained in the filter screen cylinder 91, and the remaining liquid will enter the liquid outlet pipe 2 through the connection to flow and be detected by the electromagnetic flowmeter body 4. During the detection process, the user can turn on the drive motor 9, and the drive motor 9 drives the cutting blade 93 to rotate inside the filter screen cylinder 91 through the rotating shaft 92, so as to cut the residual blockage inside the filter screen cylinder 91, and the chopped debris can pass through the mesh of the filter screen cylinder 91, so as to no longer be retained inside the filter screen cylinder 91, thereby reducing the workload of the user to frequently clean the filter screen cylinder 91. When there are many blockages inside the filter screen cylinder 91 so that the cutting and anti-blocking effect of the cutting blade 93 is reduced, the user can rotate the detachable base 7 by turning the handle 71, and the detachable base 7 is rotated out from the inside of the mounting seat 5 under the action of the first thread groove 6 and the second thread groove 8, so as to drive the filter screen cylinder 91 to leave the inside of the liquid inlet pipe 1. Then the user manually cleans it and installs it again inside the mounting seat 5 for continued use.
