Description

Technical Field

[0001] This utility model relates to the field of electromagnetic flowmeter technology, and in particular to an intelligent electromagnetic flowmeter. Background Technology

[0002] An electromagnetic flowmeter is an instrument that measures the volumetric flow rate of conductive liquids based on the principle of electromagnetic induction. It mainly consists of a sensor and a converter and is widely used in petroleum, chemical, and environmental protection fields.

[0003] The working principle of an electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. When a conductive liquid flows through a magnetic field, an induced electromotive force is generated in the direction perpendicular to both the flow direction and the magnetic field. The magnitude of this electromotive force is proportional to the flow velocity. The sensor calculates the flow rate by measuring this electromotive force, and the converter processes the signal into readable data. In practical use, particulate impurities in the fluid being measured are easily attached to the electrode surface, causing distortion of the measurement signal, reducing measurement accuracy and instrument life, and making it impractical. Therefore, it is necessary to redesign an intelligent electromagnetic flowmeter to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent electromagnetic flowmeter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An intelligent electromagnetic flowmeter includes a flowmeter body. A filter box is fixedly installed at the inlet of the flowmeter body by multiple first bolts. A filter bucket is slidably installed on the upper surface of the filter box through a sliding opening. A filter cloth is fixedly installed on the inner wall of the filter bucket. A sealing plate is fixedly installed on the upper surface of the filter bucket. A sealing gasket is fixedly installed on the bottom wall of the sealing plate. A support plate is fixedly installed on the outer wall of the filter box. A rotating shaft is rotatably installed on the upper surface of the support plate through a connecting mechanism. A connecting plate is fixedly installed on the outer wall of the rotating shaft. A hydraulic cylinder is fixedly installed on the bottom wall of the connecting plate. A pressing plate is fixedly installed on the telescopic end of the hydraulic cylinder. A pressing groove that mates with the pressing plate is formed on the upper surface of the sealing plate.

[0007] Preferably, the connecting mechanism includes a connecting block fixedly installed on the upper surface of the support plate, and the rotating shaft is rotatably installed on the upper surface of the connecting block.

[0008] Preferably, two reinforcing plates are fixedly installed on the bottom wall of the support plate, and the ends of the two reinforcing plates are fixedly connected to the outer wall of the filter box.

[0009] Preferably, a fixing plate is fixedly installed on the inner wall of the inlet of the flow meter body, and a connecting sleeve is fixedly installed on the outer wall of the fixing plate by multiple screws, and a defoaming mesh plate is fixedly installed inside the connecting sleeve.

[0010] Preferably, a pressure relief channel communicating with the interior is fixedly installed on the outer wall of the filter box inlet, and a pressure relief valve is fixedly installed at the end of the pressure relief channel by multiple second bolts.

[0012] The beneficial effects of this utility model are:

[0013] 1.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 An intelligent electromagnetic flowmeter includes a flowmeter body 1. A filter box 2 is fixedly installed at the inlet of the flowmeter body 1 by multiple first bolts. A filter bucket 3 is slidably installed on the upper surface of the filter box 2 through a sliding opening. A filter cloth 4 is fixedly installed on the inner wall of the filter bucket 3. A sealing plate 5 is fixedly installed on the upper surface of the filter bucket 3. A sealing gasket 6 is fixedly installed on the bottom wall of the sealing plate 5. A support plate 7 is fixedly installed on the outer wall of the filter box 2. A rotating shaft 9 is rotatably installed on the upper surface of the support plate 7 through a connecting mechanism. A connecting plate 10 is fixedly installed on the outer wall of the rotating shaft 9. A hydraulic cylinder 11 is fixedly installed on the bottom wall of the connecting plate 10. An extrusion plate 12 is fixedly installed on the telescopic end of the hydraulic cylinder 11. An extrusion groove that cooperates with the extrusion plate 12 is opened on the upper surface of the sealing plate 5.

[0024] Furthermore, multiple first bolts are evenly distributed at the connection between the flow meter body 1 and the filter box 2 to ensure the stability and sealing of the connection and prevent fluid leakage.

[0025] The size of the sliding opening is adapted to the filter hopper 3, so that the filter hopper 3 can slide smoothly into and out of the filter box 2, which is convenient for installation and disassembly.

[0026] The filter cloth 4 is made of high-precision, corrosion-resistant material, which can effectively intercept impurities of different particle sizes and has good wear resistance, extending its service life.

[0027] The sealing gasket 6 is made of rubber with good elasticity. When the extrusion plate 12 is pressed down, it can fit tightly against the opening of the filter box 2, further enhancing the sealing effect.

[0028] The hydraulic cylinder 11 is connected to an external hydraulic control system. By precisely controlling the inlet and outlet of hydraulic oil, the extrusion plate 12 is raised and lowered stably, ensuring reliable locking and unlocking of the sealing plate 5.

[0029] The connecting mechanism includes a connecting block 8 fixedly installed on the upper surface of the support plate 7, and a rotating shaft 9 rotatably installed on the upper surface of the connecting block 8.

[0030] Furthermore, the connecting block 8 is made of high-strength metal material and has a high-precision bearing inside, which makes the rotating shaft 9 more flexible and stable during rotation, reducing friction loss. The rotating shaft 9 and the connecting block 8 are connected by a key to prevent axial displacement of the rotating shaft 9 during rotation, ensuring the accuracy of the connecting plate 10 when rotating and facilitating the operation of the filter bucket 3.

[0031] Two reinforcing plates 13 are fixedly installed on the bottom wall of the support plate 7, and the ends of the two reinforcing plates 13 are fixedly connected to the outer wall of the filter box 2.

[0032] Furthermore, the reinforcing plate 13 has a triangular structure, which has good stability and compressive strength and can effectively disperse the pressure borne by the support plate 7. The reinforcing plate 13 is fixed to the support plate 7 and the filter box 2 by welding. The weld is uniform and full, ensuring the connection strength and ensuring that the support plate 7 will not deform or shake when the hydraulic cylinder 11 is working, thus providing a reliable guarantee for the stable operation of the entire device.

[0033] A fixing plate is fixedly installed on the inner wall of the inlet of the flow meter body 1. A connecting sleeve 14 is fixedly installed on the outer wall of the fixing plate by multiple screws. A defoaming mesh plate 15 is fixedly installed inside the connecting sleeve 14.

[0034] Furthermore, the fixing plate is firmly fixed to the inner wall of the inlet of the flow meter body 1 by welding to ensure its stability. Multiple screws are symmetrically distributed to tightly fix the connecting sleeve 14 to the fixing plate to prevent the connecting sleeve 14 from loosening. The defoaming mesh plate 15 is detachably installed in the connecting sleeve 14 for easy regular cleaning and maintenance, ensuring the durability of the defoaming effect.

[0035] A pressure relief channel 16 communicating with the interior is fixedly installed on the outer wall of the inlet of the filter box 2. A pressure relief valve 17 is fixedly installed at the end of the pressure relief channel 16 by multiple second bolts.

[0036] Furthermore, the diameter of the pressure relief channel 16 is rationally designed according to the internal pressure and flow rate of the filter box 2 to ensure that excess fluid can be discharged quickly and effectively during pressure relief. The pressure relief valve 17 is an automatic control valve with a built-in pressure sensor. When the pressure inside the filter box 2 is detected to exceed the preset threshold, it can open quickly and automatically with a short opening time and fast response speed. Multiple second bolts are evenly distributed at the connection between the pressure relief valve 17 and the pressure relief channel 16 to ensure a tight connection and prevent leakage during pressure relief.

[0037] The outlet of the pressure relief valve 17 is fixedly connected to a connecting pipe 18 by multiple third bolts, and the end of the connecting pipe 18 is connected to the inside of the outlet of the filter box 2.

[0038] Furthermore, the connecting pipe 18 is made of high-pressure resistant and corrosion-resistant pipe material with a smooth inner wall, which can reduce the resistance of fluid during transmission. Multiple third bolts firmly fix the connecting pipe 18 to the outlet of the pressure relief valve 17 to ensure the reliability of the connection.

[0039] In use, the inlet of the flow meter body 1 and the outlet of the filter box 2 can be fixedly connected by multiple first bolts. In the fluid transmission stage, the fluid enters from the inlet of the filter box 2 and is first intercepted by the filter cloth 4, effectively filtering out impurities such as mud and debris, preventing these impurities from entering the flow meter body 1 and interfering with the measurement or wearing the internal structure. The filtered fluid flows into the flow meter body 1 through the outlet of the filter box 2. During this process, the defoaming mesh plate 15 on the fixed plate begins to play its role, breaking and eliminating the air bubbles contained in the fluid, ensuring that the fluid entering the flow meter body 1 is stable and improving the accuracy of the measurement data.

[0040] When impurities accumulate inside the filter hopper 3, affecting fluid flow, the pressure protection mechanism formed by the pressure relief channel 16 and pressure relief valve 17 at the inlet of the filter box 2 is immediately activated. The pressure relief valve 17 automatically opens, and the high-pressure fluid flows back to the outlet of the filter box 2 through the pressure relief channel 16 and connecting pipe 18, and then enters the flow meter body 1, thereby releasing the system pressure and ensuring fluid flow. When it is necessary to clean the filter cloth 4, the hydraulic cylinder 11 is activated, causing its extension end to drive the extrusion plate 12 upward, disengaging it from the extrusion groove on the sealing plate 5. Then, the rotating shaft 9 is rotated, moving the connecting plate 10 and the hydraulic cylinder 11 and other components to the side, releasing the restriction on the sealing plate 5, and the filter hopper 3 can be easily removed. After replacement, the operation is reversed, using the hydraulic cylinder 11 to drive the extrusion plate 12 downward, and in conjunction with the sealing gasket 6, the sealing plate 5 is tightly fixed to ensure the sealing of the filter box 2 and prevent fluid leakage. In addition, the presence of the reinforcing plate 13 always provides stable support for the support plate 7, ensuring the stable operation of the rotating shaft 9, hydraulic cylinder 11 and other components, and ensuring the reliability and convenience of maintenance operations.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
