Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic equipment, in particular to an anti-crystallization structure of a flow meter used for electrolyte. Background Art

[0002] The principle of manganese dioxide electrolysis equipment is to pump the electrolyte into the high-level soap through a pump, and then the electrolyte in the high-level soap flows into the electrolytic cell for electrolysis. The flow rate of the electrolyte entering the electrolytic cell affects the electrolytic reaction rate and the quality of the electrochemical reaction. Therefore, it is necessary to monitor and control the flow rate of the electrolyte entering the electrolytic cell and maintain an appropriate level to ensure the reaction quality.

[0003] Flowmeter is a commonly used instrument for measuring fluid flow. When the existing flowmeter is used for electrolyte flow measurement, the pipeline is very likely to be blocked due to crystallization. The reasons are: the electrolyte has high calcium and magnesium content and additives stick together; the flowmeter measurement accuracy requires a smaller pipe diameter; the electrolyte itself is very likely to crystallize at pipe connections or rough places; due to the presence of microcurrent in the electrolyte, microelectrolysis will occur when it encounters metal parts, producing black hard crystals, which accelerates the crystallization and blockage of the pipeline. Summary of the invention

[0004] In view of the above problems existing in the prior art, the utility model provides a flow meter anti-crystallization structure.

[0005] The technical solution adopted by the utility model is as follows: A flowmeter anti-crystallization structure, including a flowmeter body, the flowmeter body is provided with a liquid inlet connected to the process pipeline, the outer wall of the liquid inlet is a straight pipe, the process pipeline is sleeved on the outer wall of the liquid inlet, the liquid inlet includes an outer tube and a lining, the lining is made of insulating and anti-corrosion material, and the lining completely covers the outer tube so that the outer tube does not contact the liquid flowing through, the inner diameters of the outer tube and the lining are both tapered from the outside to the inside, and the outermost end of the lining is a thin-walled design.

[0006] Furthermore, the material of the lining is fluoroplastic.

[0007] Furthermore, the inner wall of the lining is mirror-finished.

[0008] Furthermore, the process pipeline is sleeved on the liquid inlet by an interference fit, and is tightly connected to the liquid inlet by a clamp, and the clamp corresponds to the outer tube of the liquid inlet.

[0009] Furthermore, the flowmeter body is an electromagnetic flowmeter.

[0010] The beneficial effects of the utility model are as follows: the connection method between the flow meter and the process pipeline in the utility model cancels the traditional flange connection, and adopts a sleeve straight-through connection, which avoids crystallization of the electrolyte at the flange joint. The liquid inlet adopts a unique structural design and the internal diameter is smoothly reduced, which not only ensures the measurement accuracy requirements, but also has a smooth transition between the lining and the process pipeline, improves the crystallization and scaling phenomenon in the pipe, and the inner wall is treated with a fluorine lining mirror, the inside of the conduit is smoother, and there is no uneven defect inside the conduit, so it is not easy to scale. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively and carefully below in conjunction with the accompanying drawings and preferred embodiments of the specification, but the protection scope of the present invention is not limited to the following specific embodiments.

[0013] like Figure 1 As shown, a flowmeter anti-crystallization structure of the present embodiment includes a flowmeter body 1. In the present embodiment, the flowmeter body 1 is an electromagnetic flowmeter. The flowmeter body 1 is provided with a liquid inlet 2 that is connected to the process pipeline 3. The outer wall of the liquid inlet 2 is a straight pipe. The process pipeline is sleeved on the outer wall of the liquid inlet 2. The liquid inlet 2 includes an outer tube 201 and a lining 202. The lining 202 is made of insulating and anti-corrosion material. In the present embodiment, fluoroplastic is used. In order to better achieve insulation, corrosion resistance, and crystallization resistance, the lining 202 completely covers the outer tube 201 so that the outer tube 201 does not contact the liquid flowing through. The inner diameters of the outer tube 201 and the lining 202 are both set to gradually decrease from the outside to the inside. By reducing the diameter, the measurement accuracy of the flowmeter can be improved. The outermost end of the lining 202 is designed with a thin wall, so that the lining 202 and the process pipeline 3 have a smooth transition to prevent crystallization.

[0014] In order to make the pipe wall smoother and less prone to scaling, the inner wall of the lining 202 is mirror-finished.

[0015] To make the connection more stable, in this embodiment, the process pipeline is sleeved on the liquid inlet 2 by an interference fit and is fastened to the liquid inlet 2 by a clamp, and the clamp corresponds to the outer tube 201 of the liquid inlet 2.

Therefore, it is to be understood that the present invention is not limited to the specific embodiments disclosed, and modifications and other embodiments are considered to be included within the scope of the appended claims.
