Abstract
Description
Technical Field
[0001] The utility model relates to a solution oxygen measuring device, in particular to a membrane rack device which can measure dissolved oxygen in a high temperature environment. Background Art
[0002] Dissolved oxygen (DO) occurs when oxygen molecules in the air dissolve in water. Dissolved oxygen is one of the indicators used by environmental protection agencies for water quality monitoring. Conventional methods for measuring DO include electrode methods, which offer advantages such as ease of operation, minimal interference during measurement, and the ability to achieve continuous and rapid online monitoring. However, at high temperatures, the pressure differential between the inside and outside of the membrane frame can cause the diaphragm to deform, making measurement impossible.
[0003] To address the above issues, we have made a series of improvements. Utility Model Content
[0004] The purpose of the utility model is to provide a membrane rack device that can measure dissolved oxygen in a high temperature environment, so as to overcome the above-mentioned shortcomings and deficiencies of the prior art.
[0005] A membrane frame device capable of measuring dissolved oxygen in a high-temperature environment, comprising: a tight ring, a sealing ring, a membrane, a protective net, and a membrane frame sleeve, wherein the tight ring is connected to the membrane frame sleeve via the sealing ring, the membrane is fixedly connected to the protective net via glue, and the membrane and the protective net are connected to the membrane frame sleeve;
[0006] Among them, the protective net is provided with a mesh pattern, a protective frame, an installation groove, a clamp and a buckle body. The mesh pattern is arranged on the surface of the protective net, the protective frame is connected to the outer ring of the protective net, the installation groove is arranged on the protective frame, the clamp is connected to the inside of the installation groove, and the clamp is connected to the inside of the membrane frame sleeve through the buckle body.
[0007] Beneficial effects of the utility model:
[0008] Compared with traditional technologies, this utility model adopts high-temperature resistant materials and adds a protective net structure on the surface of the membrane to improve the strength of the membrane at high temperatures and avoid rupture. The protective net is easy to install and convenient for future maintenance and replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below in conjunction with specific embodiments. It should be understood that the following embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0015] Example 1
[0016] Figure 1 It is a structural diagram of the present utility model. Figure 2 This is a schematic diagram of the protective net structure of the present utility model. Figure 3 It is a partial structural diagram of the protection net of the present utility model.
[0017] like Figures 1 to 3 As shown, a membrane frame device capable of measuring dissolved oxygen in a high temperature environment includes: a tight ring 100, a sealing ring 200, a membrane 300, a protective net 400, and a membrane frame sleeve 500. The tight ring 100 is connected to the membrane frame sleeve 500 through the sealing ring 200, the membrane 300 is fixedly connected to the protective net 400 by glue, and the membrane 300 and the protective net 400 are connected to the membrane frame sleeve 500.
[0018] Among them, the protective net 400 is provided with a mesh pattern 410, a protective frame 420, an installation groove 430, a claw 440 and a buckle body 450. The mesh pattern 410 is arranged on the surface of the protective net 400, the protective frame 420 is connected to the outer ring of the protective net 400, the installation groove 430 is arranged on the protective frame 420, the claw 440 is connected to the inside of the installation groove 340, and the claw 440 is connected to the inside of the membrane frame sleeve 500 through the buckle body 450.
[0019] The principle of this utility model is to first use glue to firmly fix the protective net 400 and the membrane 300 to prevent displacement. The protective net 400 uses the protective frame 420 of the outer ring to form a protective layer. Then, the fixed membrane 300 is installed in the membrane frame sleeve 500 through the clamping body 450 of the clamping catch 440 on the installation groove 430. The mesh pattern on the protective net 400 can disperse and absorb heat and protect the membrane 300 from external damage, extending the service life of the membrane 300. Finally, the tightening ring 100 is screwed in and sealed by the built-in sealing ring 200. The utility model uses high-temperature resistant materials and adds a protective net structure on the surface of the membrane to improve the strength of the membrane at high temperatures and prevent rupture. The protective net is simple to install, which is convenient for future maintenance and replacement.
[0020] The above describes the specific implementation of the present invention, but the present invention is not limited thereto. As long as it does not deviate from the purpose of the present invention, the present invention can also have various changes.
