Description

Technical Field

[0001] This utility model relates to the technical field of Karl Fischer moisture analyzers, and in particular to a Karl Fischer moisture analyzer with quick reagent replacement. Background Technology

[0002] A Karl Fischer moisture analyzer is an instrument used to accurately determine the moisture content of substances. It is widely used in chemistry, medicine, food, and other fields. Its basic principle is based on the chemical reaction in which iodine oxidizes sulfur dioxide, requiring a specific amount of water. By measuring the volume (capacity) of the Karl Fischer reagent consumed, the moisture content of the sample can be calculated.

[0003] However, existing Karl Fischer moisture analyzers require the solutions in the cathode and anode chambers to be poured out separately when reagents need to be replaced, which increases the workload and operational steps for staff to dispose of waste liquid and reduces efficiency. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The purpose of this invention is to provide a Karl Fischer moisture analyzer with rapid reagent replacement, thereby solving the problem mentioned in the background art that existing Karl Fischer moisture analyzers require the solutions in the cathode and anode chambers to be poured out separately when reagent replacement is needed, which increases the workload and operation steps for workers to dispose of waste liquid and reduces the efficiency of use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a Karl Fischer moisture analyzer with rapid reagent replacement, comprising an instrument body, an anode chamber slidably connected to the inner wall of one side of the instrument body, a cathode chamber slidably connected to the top of the anode chamber, a telescopic assembly fixedly connected to the inner top wall of the cathode chamber, a filter membrane fixedly connected to the bottom end of the telescopic assembly, a support shell sleeved on the back of the instrument body, a fixed cover fixedly connected to the inner top wall of the support shell, a winding assembly snapped into the inner wall of the fixed cover, the telescopic assembly including a telescopic spring fixedly connected to the inner top wall of the cathode chamber, a limit ring fixedly connected to the bottom of the telescopic spring, a push rod sleeved inside the limit ring; the winding assembly including a spring snapped into the inner wall of the fixed cover, a rotating shaft snapped into one end of the spring, a power cord sleeved on the surface of the rotating shaft.

[0007] As a further embodiment of this invention, a measuring electrode is inserted into the top of the anode chamber, and an electrolytic electrode is inserted into the top of the cathode chamber. The electrolytic electrode facilitates the generation of an electrolytic reaction.

[0008] As a further embodiment of this invention, a drying tube is inserted into the top of both the anode chamber and the cathode chamber, and a desiccant is placed inside the drying tube. The desiccant helps to absorb moisture.

[0009] As a further embodiment of this utility model, a support frame is fixedly connected to one side of the measuring instrument body, a waste liquid collection bottle is inserted into one side of the top surface of the support frame, and a solution bottle is inserted into the other side of the top surface of the support frame. The solution bottle serves to store the solvent.

[0010] As a further embodiment of this utility model, a delivery pump is connected through the top of both the waste liquid collection bottle and the solution bottle, and a delivery pipe is connected through one end of the delivery pump. The delivery pipe serves to transport the liquid.

[0011] As a further embodiment of this utility model, a sample injection port is connected through one side of the anode chamber, and a sample injection cap is sleeved on one end of the sample injection port. The sample injection cap facilitates the injection of reagents.

[0012] As a further embodiment of this utility model, a sealing plug is inserted into the top of the cathode chamber, and a plug is fixedly connected to one end of the power cord. The plug facilitates connection to an external power source.

[0013] This invention provides a Karl Fischer moisture analyzer with rapid reagent replacement, which has the following advantages:

[0014] 1. This Karl Fischer moisture analyzer with rapid reagent replacement utilizes a telescopic assembly. When reagent replacement is needed, the waste liquid in the anode chamber is extracted by activating the corresponding delivery pump in the waste liquid collection bottle. Then, pressing the push rod causes it to push the filter membrane, disengaging it from the cathode chamber and discharging the waste liquid from the cathode chamber. This waste liquid is then discharged into the waste liquid collection bottle via a delivery pipe. The electrolytic solution in the solution bottle is then extracted, and the solution is injected into both the cathode and anode chambers using the sealing plug on the cathode chamber. This achieves convenient replacement of the solutions and reagents in the cathode and anode chambers, reducing the workload of waste liquid disposal and improving the working efficiency of the Karl Fischer moisture analyzer.

[0015] 2. This Karl Fischer moisture analyzer with quick reagent replacement features a winding assembly. During use, pulling the plug allows the power cord to be pulled out and unwound from the rotating shaft. This causes the top of the shaft to activate a spring, which in turn pulls the shaft. When finished, the spring pulls the shaft to wind up the power cord, effectively storing it and preventing damage from tangled wiring. This also reduces space requirements and extends the lifespan of the Karl Fischer moisture analyzer. Attached Figure Description

A filter membrane 5 is fixedly connected to the bottom end of the telescopic component 4. A support shell 6 is sleeved on the back of the instrument body 1, and a fixed component is fixedly connected to the inner top wall of the support shell 6. The inner wall of the cover 7 is fitted with a winding assembly 8. The winding assembly 8 is designed to store the power cord 803, preventing damage caused by messy wiring during instrument use. It also reduces space occupation and improves the service life of the Karl Fischer moisture analyzer. The telescopic assembly 4 includes a telescopic spring 401 fixedly connected to the top wall of the cathode chamber 3. The bottom of the telescopic spring 401 is fixedly connected to a limit ring 402. A push rod 403 is sleeved inside the limit ring 402. The winding assembly 8 includes a spring 801 fitted with the inner wall of the cover 7. One end of the spring 801 is fitted with a rotating shaft 802. The surface of the rotating shaft 802 is sleeved with the power cord 803.

[0023] A measuring electrode 9 is inserted into the top of the anode chamber 2, and an electrolysis electrode 10 is inserted into the top of the cathode chamber 3. The electrolysis electrode 10 facilitates the generation of an electrolysis reaction.

[0024] A drying tube 11 is inserted into the top of both the anode chamber 2 and the cathode chamber 3. The inside of the drying tube 11 is filled with desiccant, which absorbs moisture.

[0025] A support frame 12 is fixedly connected to one side of the instrument body 1. A waste liquid collection bottle 13 is inserted into one side of the top surface of the support frame 12, and a solution bottle 14 is inserted into the other side of the top surface of the support frame 12. The solution bottle 14 serves to store the solvent.

[0026] Both the waste liquid collection bottle 13 and the solution bottle 14 are connected to a transfer pump 15. One end of the transfer pump 15 is connected to a transfer pipe 16, which serves to transfer liquid.

[0029] In this invention, the working steps of the device are as follows:

[0032] Third step: When in use, the person pulls the plug 20, so that the power cord 803 is pulled out from the surface of the shaft 802 and unfolded. Then the top of the shaft 802 drives the spring 801, so that the spring 801 deforms and generates elastic force, which in turn pulls the shaft 802. When the use is over, the spring 801 pulls the shaft 802 to wind up the power cord 803.
