Description

Technical Field

[0001] The utility model relates to the field of electrodes, in particular to a disposable pH composite electrode used in a biological fermentation process. Background Art

[0002] Online pH electrodes have been widely used in tap water, river water, chemical industry, medicine and other industries. In the biological fermentation industry, pH value control during the fermentation process is necessary, and a fermentation cycle is fully enclosed, and the pH electrode needs to work stably during this process. Currently, the electrodes on the market are mainly installed on the fermentation tank by threading. Due to the different sizes of fermentation tanks, the electrode sizes are also different, usually 120mm-425mm, which is not convenient to use and may break the electrode. In addition, the performance of the electrode will slowly decline with use, affecting the accuracy of the test results, which may cause fermentation failure and bring great economic losses.

[0003] To solve the above problems, we made a series of improvements. Utility Model Content

[0017] The following is a further description of the present invention in conjunction with specific embodiments. It should be understood that the following embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0018] Example 1

[0019] Figure 1 It is a structural schematic diagram of the utility model.

[0020] like Figure 1 As shown, a disposable pH composite electrode for use in a biological fermentation process comprises: a measuring housing 100, a reference liquid junction 200, an internal reference silver wire 300, an external reference silver wire 400 and a Bluetooth transmission microcircuit 500, wherein the reference liquid junction 200 is connected to the measuring housing 100, the internal reference silver wire 300 is arranged inside the measuring housing 100, the external reference silver wire 400 is arranged inside the reference liquid junction 200, and the internal reference silver wire 300 and the external reference silver wire 400 are connected to the Bluetooth transmission microcircuit 500;

[0021] Among them, the reference liquid connection part 200 includes: a sand core 210, an external reference cavity 220 and an external reference gel 230. The sand core 210 is connected to the outside of the measuring housing 100, the external reference cavity 220 is arranged inside the sand core 210, the external reference gel 230 is arranged inside the external reference cavity 220, and an external reference silver wire 400 is arranged inside the external reference gel 230.

[0022] An internal reference solution 110 is disposed inside the measuring housing 100 , and an internal reference silver wire 300 is disposed inside the internal reference solution 110 .

[0023] A temperature probe 510 is provided on the Bluetooth transmission microcircuit 500 , and the temperature probe 510 is connected to the Bluetooth transmission microcircuit 500 .

[0024] The internal reference silver wire 300 is spiral or folded.

[0025] The installation and use method of the utility model is that a sand core 210 is sintered on the measuring housing 100 as the reference liquid junction 200, an appropriate internal reference solution 110 is added to the middle glass tube of the measuring housing 100, and the internal reference silver wire 300 is encapsulated therein, an external reference gel 230 is added to the external reference cavity 220, and the external reference silver wire 400 is encapsulated therein, and finally the external reference silver wire 400 and the internal reference silver wire 300 lead wire are welded and encapsulated with the Bluetooth transmission microcircuit 500. The electrode is placed in a biological fermentation tank for measurement and data transmission via Bluetooth.

[0026] Compared with the conventional technology, the present invention has the following advantages: first, the internal reference silver wire 300 of the present invention is installed in a spiral or folding type. Since the length of the electrode is shortened, the contact area between the silver wire and the internal reference solution 110 is too small compared to the conventional linear installation, which easily causes potential anomalies. The use of a spiral or folding type can effectively increase its contact area and ensure stability. Second, in order to extend the service life of the electrode, conventional electrodes generally adopt a long-lasting external reference structure, which is relatively large and requires a certain internal space. The present invention is a disposable electrode. On the premise of ensuring one-time accuracy, a simple silver-silver chloride (dip plating process) can meet the requirements, which solves the space problem very well. Third, conventional electrodes have an integrated temperature probe for temperature compensation during the measurement process. The present invention does not integrate the temperature internally, but integrates the temperature probe 510 into the Bluetooth transmission microcircuit 500, which can free up space for the electrode and facilitate the assembly of other parts. Fourth, the electrodes of analog signals generally need to be connected to the equipment to perform normal measurement and reading, but the electrodes are integrated with the Bluetooth transmission microcircuit 500, and the user can read the data with a mobile phone after connecting the Bluetooth on the circuit. The utility model is used for pH monitoring in the process of biological fermentation, which can provide reliable detection results and improve the convenience of use for users.

[0027] Compared with the traditional technology, the utility model has a smaller volume, can be connected to a microcircuit, and transmit data via Bluetooth. At the same time, the electrode can be thrown into the fermentation tank as a whole, and can be discarded after a fermentation cycle is completed. In addition, each fermentation cycle is monitored with a new electrode, and the reliability of the result is guaranteed, and the tedious steps of installation can be omitted.

[0028] The specific implementation modes of the present invention are described above, but the present invention is not limited thereto. The present invention can also have various changes without departing from the purpose of the present invention.
