Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tank auxiliary equipment, in particular to a pH electrode calibration bracket for a fermentation tank. Background Art

[0002] During the use of the fermentation tank, the pH electrode needs to be calibrated. During the calibration process, the pH electrode needs to be taken out frequently. In order to avoid environmental factors affecting the pH electrode, the operator can only temporarily hold the pH electrode, which directly affects the safety of the calibration experiment. If the pH electrode is placed in a container or on a stage after being taken out, the residual liquid on the pH electrode will cross with the substances in the container, affecting the accuracy of the calibration after it is inserted into the fermentation tank again. Utility Model Content

[0003] The utility model aims to solve the above problems and provides a fermentation tank pH electrode calibration bracket, which is used for temporary storage of pH electrodes and avoids contact between the pH electrode body and external substances.

[0004] The technical solution adopted by the utility model is:

[0006] Furthermore, the sleeve ring is of a separate type, and comprises two semi-circular ring disks, which are sleeved on the tank rack after being locked by adjusting screws on the sides.

[0007] Furthermore, a semicircular groove is formed at the rear end of the support plate, and two ends of the semicircular groove are respectively mounted on two semicircular ring grooves through fasteners.

[0008] Furthermore, the fermenter has three tank racks, which are arranged between the eaves of the fermenter body and the base, and the electrode calibration bracket is arranged on one or more of the three tank racks.

[0009] Furthermore, the fermentation tank cover is provided with an electrode socket for inserting a pH electrode.

[0010] The beneficial effects of the utility model are:

[0011] (1) Using the fermentation tank rack to install the bracket will not increase the burden on the equipment;

[0012] (2) The bushing is used to insert the pH electrode, and the pH electrode inserted into the liquid does not have direct contact with the bracket;

[0013] (3) The collar fixes the bracket at different heights and angles by adjusting the screws. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The specific implementation of the fermentation tank pH electrode calibration bracket of the utility model is described in detail below in conjunction with the accompanying drawings.

[0028] See attached Figure 1 The fermentation tank body 1 is supported by three tank racks 3 on the base 2. The top of the tank body 1 is sealed by a tank cover 4. Various measuring instruments and liquid inlet and outlet pipes are provided on the tank cover 4. The pH electrode 15 is inserted through the electrode jack 5 on the tank cover 4 to measure the liquid inside the tank body 1.

[0029] When calibrating the pH electrode 15 , the pH electrode 15 needs to be taken out and put in multiple times. When calibrating multiple pH electrodes, this taking out and putting in is more frequent.

[0030] See attached Figure 2The calibration bracket 6 of the present patent includes a collar 7 arranged on the tank rack 3. The collar 7 is a separate type, including two semicircular ring disks 8. The two semicircular ring disks 8 are sleeved on the tank rack 3 after being locked by the side adjustment screws 9. A support plate 10 is fixedly installed on the collar 7. A through hole 11 is opened at the front end of the support plate 10. The length of the support plate 10 makes the through hole 11 located outside the edge of the fermentation tank. An electrode bushing 12 is arranged in the through hole 11 for inserting a pH electrode 15 into the pH electrode bushing 12. A semicircular groove 13 is formed at the rear end of the support plate 10. The two ends of the semicircular groove 13 are respectively installed on the two semicircular ring disks 8 by screws 14. The semicircular groove 13 is used to avoid the tank rack 3.

[0031] When in use, insert the two semicircular ring disks 8 into the tank rack 3, tighten the adjusting screws 9 to fix them on the tank rack 3, then fix the rear end of the support plate 10 on the two semicircular ring disks 8, and clamp the bushing 12 on the through hole 11 at the front end of the support plate 10. After completion, according to the height and use position of the pH electrode 15, loosen the adjusting screws 9, move up and down, and rotate the collar 7, so that the collar 7 is fixed at a specific height of the tank rack 3, and the support plate 10 is rotated to a specific angle.

[0032] The number of calibration brackets 6 for pH electrodes can be one or more mounted on the three tank racks 3 according to experimental requirements.

[0033] See attached Figure 3 , 4 ,When working, the calibration bracket 6 is located at different heights to meet different ,experimental requirements.

[0034] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
