Description

Technical Field

[0001] The present application relates to the field of electrochemistry technology, and mainly relates to a constant-temperature positioning fixture for electrolytic water plates. Background Art

[0002] In recent years, the hydrogen energy industry has developed rapidly globally. In particular, the power generation methods using anion (AEM) or cation (PEM) membranes as diaphragms are also developing rapidly. Therefore, the testing of membrane electrodes for these new energy sources is particularly important, and some specific test fixtures are often used for testing during testing.

[0003] However, the existing test fixtures cannot accurately control conditions such as test pressure and temperature during use, and the operation is not stable enough and the data collection is unreliable, which greatly affects the experimental performance of the membrane electrode.

[0004] Therefore, it is of great significance to improve the existing membrane electrode test fixtures. Summary of the Utility Model

[0005] Aiming at the technical problems that the existing membrane electrode test fixtures cannot accurately control conditions such as test pressure and temperature and the operation is not stable enough, the present application proposes a constant-temperature positioning fixture for electrolytic water plates.

[0006] A constant-temperature positioning fixture for electrolytic water plates proposed by the present utility model includes a slide rail, a slider, a first heating plate and a second heating plate; the slider is arranged on the slide rail and moves up and down along the slide rail; the first heating plate is fixedly installed with the slider through a connection component; the second heating plate is horizontally fixedly installed on the working platform; a pair of electrolytic water plates are clamped between the first heating plate and the second heating plate; the first heating plate is provided with a first heating cavity, and the second heating plate is provided with a second heating cavity; a ceramic heating sheet and a temperature sensor are arranged in both the first heating cavity and the second heating cavity; the first heating plate, the second heating plate, the electrolytic water plates, the first heating cavity and the second heating cavity are coaxially arranged.

[0007] This fixture realizes the temperature control of the electrolytic water plates through the upper and lower heating plates. At the same time, relying on components such as the slide rail and the slider, the tightness between the two electrolytic water plates can be easily controlled, so as to control the pressure parameters between the flow channels of the electrolytic water plates and the proton exchange membrane and the catalyst, thereby realizing the rapid response and accurate control of the test temperature and pressure.

[0008] Preferably, it further includes a fixed triangular plate, and the fixed triangular plate is fixedly installed and connected with the slide rail and the working platform respectively. The fixed triangular plate is simple to install and has a stable structure, which can ensure that the fixture is firmly installed on the working platform and provide guarantee for the accurate control of pressure by the fixture.

[0009] Preferably, the slider includes an electric cylinder drive or a cylinder drive. The electric cylinder drive device has good stability, can achieve extremely high position accuracy and speed accuracy through programming, and has a simple structure, small volume, light weight, and convenient installation; the cylinder drive device is easy to operate, adapts to various working environments, and can provide a large torque output. By controlling the movement of the slider with the two drive devices, it is possible to ensure that the fixture continuously provides stable pressure.

[0010] Preferably, a locking knob is further provided on the slider. The slider is locked by the locking knob to prevent the fixture from still providing stable pressure when the drive device fails or there is no drive device.

[0011] Preferably, a rotating mounting disc is further provided on the slider, which is used to provide a fixed point for devices that need to be rotated and mounted at an angle. Through the rotating mounting disc, other accessory parts can be installed on the fixture itself, enriching the functions of the fixture.

[0012] Preferably, it further includes an aerogel thermal insulation pad, which can be fixedly installed between the second heating plate and the working platform. The aerogel thermal insulation pad is fixedly installed on the working platform through connecting screws. Through the aerogel thermal insulation pad, the heat generated by the heating plate will not affect the bottom working platform. Using connecting screws helps to firmly fix the aerogel thermal insulation pad, and it is also convenient for installation, maintenance, and replacement.

[0013] Preferably, both the first heating plate and the second heating plate are provided with electrode plate positioning holes, and the electrolytic water electrode plates are provided with electrode plate through holes corresponding to the electrode plate positioning holes. A positioning pin is inserted into the electrode plate positioning hole to assist in the fixed installation of the electrolytic water electrode plates. The electrode plate positioning holes ensure the accurate installation positions of the two electrolytic water electrode plates. Using the positioning pin can also greatly improve the strength and stability of the connecting components, and the positioning pin is simple and convenient to operate during the assembly and disassembly process.

[0014] Preferably, both the first heating plate and the second heating plate are provided with replacement openings for the ceramic heating sheets. By providing the replacement openings for the ceramic heating sheets, the ceramic heating sheets can be replaced and repaired without disassembling the heating plates.

[0015] Preferably, the temperature sensor is installed on the ceramic heating sheet. This design can make the temperature sensing data more accurate, and it is also convenient for the replacement and repair of the temperature sensor.

[0016] Compared with the prior art, the beneficial effects of the present application are as follows:

[0017] (1) The constant-temperature positioning fixture for electrolytic water plates of the present application can achieve precise control of the pressure between two electrolytic water plates in cooperation with a driving device such as an electric cylinder or a cylinder, thereby controlling the pressure parameters between the flow channels of the electrolytic water plates, the proton exchange membrane, and the catalyst.

[0018] (2) The constant-temperature positioning fixture for electrolytic water plates of the present application realizes precise temperature control of the electrolytic water plates through upper and lower heating plates, and its efficiency and effect are far superior to indirectly controlling the temperature inside the plates by preheating pure water.

[0019] (3) The installation and disassembly of the constant-temperature positioning fixture for electrolytic water plates of the present application have the advantages of being portable and fast, and it operates stably and collects reliable data, which can greatly improve the test performance of the membrane electrode.
