Technical Field

[0001] This utility model relates to a chemical testing instrument, and in particular to a diaphragm electrolytic electrode replenishment device for a moisture analyzer. Background Technology

[0002] Currently, the electrolytic electrodes in the moisture analyzers have ceramic membranes and small electrolytic cells inside. The addition and discharge of reagent electrolytes require the operator to manually open the lid, which is quite troublesome. In addition, atmospheric humidity is involved every time the lid is opened. If the internal moisture is not blown out before the test, the measurement accuracy will be affected. Therefore, a device that can solve the above problems is needed. Summary of the Invention

[0004] Therefore, it is now necessary to disclose a device that can solve the above problems: a moisture analyzer diaphragm electrolysis electrode replenishment device, including a moisture analyzer, a vacuum pump, and a solenoid three-way valve.

[0005] In this device, a replenishment tube, a drain tube, and a depressurization drying tube are inserted into the upper ground joint of the inner electrolytic cell of the diaphragm electrolytic electrode of the moisture tester. The other end of the replenishment tube is connected to the replenishment bottle, and the other end of the drain tube is connected to the drain receiving bottle. The drain receiving bottle is connected to the outlet of the vacuum pump via an air suction pipe and a pump inlet solenoid three-way valve. The replenishment bottle is connected to the inlet of the vacuum pump via an air blowpipe and a blowpipe exhaust solenoid three-way valve.

[0006] Furthermore, the pressure-reducing drying tube is connected to the drying container, which is filled with desiccant particles. The air inlet of the vacuum pump is connected to a pump inlet solenoid three-way valve, which has an air inlet pipe connected to the atmosphere.

[0007] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0008] This utility model discloses a diaphragm electrolytic electrode replenishment and drainage device for a moisture tester. It uses the blowing and suction action of a vacuum pump to replenish and drain the electrolytic cell of the moisture tester. Its structure is simple. It addresses the problems of time-consuming, labor-intensive, and inefficient traditional manual operation by designing a special structure that can control the replenishment and addition of liquid according to the testing needs.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention is not limited to the specific embodiments disclosed below.

[0014] Please see Figure 1 This utility model provides a device for replenishing and draining the electrolyte in a diaphragm electrolytic electrode of a moisture analyzer, comprising:

[0015] 1. Vacuum pump; 2. Pump inlet solenoid three-way valve; 3. Air suction tube; 4. Drying container; 5. Air blow-off tube; 6. Replenishment bottle; 7. Ceramic membrane electrolytic electrode; 8. Replenishment tube; 9. Drainage tube; 10. Calvshut tester body; 11. Air blow-off solenoid three-way valve; 12. Air venting tube; 13. Drainage receiving bottle; 14. Pressure reducing drying tube.

[0016] A replenishment tube 8, a drain tube 9, and a pressure-reducing drying tube 14 are inserted into the upper ground joint of the inner electrolytic cell of the diaphragm electrolytic electrode of the moisture tester. The other end of the replenishment tube 8 is connected to the replenishment bottle 6, and the other end of the drain tube 9 is connected to the drain receiving bottle 13. The drain receiving bottle 13 is connected to the outlet of the vacuum pump 1 through the air suction tube 3 and the pump inlet solenoid three-way valve 2. The replenishment bottle 6 is connected to the inlet of the vacuum pump 1 through the air blow pipe 5 and the blow pipe exhaust solenoid three-way valve 11.

[0017] Specifically, the depressurization drying tube 14 is connected to the drying container 4, and the drying container 4 is filled with desiccant particles.

[0018] Specifically, the air inlet of vacuum pump 1 is connected to the normally open terminal of a pump inlet solenoid three-way valve 2. The normally closed terminal of this three-way valve is connected to atmospheric air. The common terminal of this three-way valve is connected to an air suction pipe 3, which is connected to a drain receiving bottle 13. Please refer to [link to relevant documentation]. Figure 2 When replenishing the reagent electrolyte in the internal electrolytic cell, the vacuum pump 1 is started. Air enters the vacuum pump 1 through the normally closed end of the pump inlet solenoid three-way valve 3, and is blown into the replenishment bottle 6 through the air blow-out pipe 5 and the air exhaust solenoid three-way valve 11 along the direction of the pipeline arrow.

Air is drawn out of the drain receiving bottle 13 through the air suction pipe 3, creating a negative pressure. This negative pressure draws the electrolyte from the internal electrolytic cell of the ceramic electrolytic electrode through the drain pipe 9 into the drain receiving bottle 13. During the draining process, the air drawn out by the vacuum pump 1 is discharged into the atmosphere through the vent pipe 12, which is connected to the common end of the blowpipe vent three-way valve 11.
