Description

Technical Field

[0001] This utility model relates to the field of moisture analyzers, and in particular to a moisture analyzer. Background Technology

[0002] A moisture analyzer is an instrument used to measure the moisture content of substances and is widely used in food, chemical, pharmaceutical, and agricultural fields.

[0003] One of them is the Karl Fischer moisture analyzer. The Karl Fischer moisture analyzer is divided into two types: volumetric and coulometric. The volumetric method calculates the moisture content based on the amount of titrant consumed by reacting the titrant with the moisture in the sample. The coulometric method calculates the moisture content based on the amount of electricity consumed by reacting the iodine generated by electrolysis with the moisture in the sample. It has the characteristics of high measurement accuracy and good repeatability, and is suitable for the determination of trace moisture.

[0004] Because the Karl Fischer moisture analyzer consumes water during operation, a vent is provided on the housing, and a perforated plate is installed on the vent for protection. However, when the Karl Fischer moisture analyzer is not in use, dust will fall onto the perforated plate, and external debris particles will fall into the Karl Fischer moisture analyzer from the perforated plate, thus affecting the accuracy of the test and thus having a certain defect.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1

[0038] This utility model provides, for example Figure 1-2The moisture analyzer shown includes a moisture analyzer body 1, a mounting sleeve 2, a first mesh plate 3, a second mesh plate 4, a handle plate 5, a locking assembly 6, a sliding hole, and a docking groove. The top of the moisture analyzer body 1 has an exhaust port. The mounting sleeve 2 is fixedly mounted on the top of the moisture analyzer body 1. The first mesh plate 3 is fixedly fitted inside the mounting sleeve 2, and the second mesh plate 4 is fitted inside the mounting sleeve 2. The mesh holes on the second mesh plate 4 are misaligned with the mesh holes on the first mesh plate 3 to seal the first mesh plate 3. The mesh holes on the first mesh plate 3 and the second mesh plate 4 correspond to each other, so that when the mesh holes on the second mesh plate 4 overlap with the mesh holes on the first mesh plate 3, the exhaust port of the moisture analyzer body 1 can be opened. The discharged gas is discharged through the mesh holes on the first mesh plate 3 and the second mesh plate 4. The handle plate 5 is disposed between the second mesh plate 4 and the mounting sleeve 2. The sliding hole is opened on the side of the mounting sleeve 2. The outer wall of the handle plate 5 is slidably sleeved with the inner cavity of the sliding hole. The mating groove is opened on the side of the second mesh plate 4. One end of the outer wall of the handle plate 5 is slidably sleeved with the inner cavity of the mating groove. The handle plate 5 is used to drive the second mesh plate 4 to rotate. That is, when the handle plate 5 slides in the sliding hole, it can drive the second mesh plate 4 to rotate relative to the mounting sleeve 2. When the handle plate 5 is located on both sides of the sliding hole, the mesh holes on the second mesh plate 4 and the mesh holes on the first mesh plate 3 are respectively in a misaligned and overlapping state. The locking component 6 is disposed between the handle plate 5 and the mounting sleeve 2.

[0039] Example 2

[0040] Based on Example 1, such as Figure 3 As shown, the locking assembly 6 includes a slider 61, an arc groove, a positioning rod 62, and a positioning slot. The bottom of the outer wall of the slider 61 is slidably inserted into the handle plate 5. The arc groove is opened at the top of the inner wall of the sliding hole. The top of the outer wall of the slider 61 is slidably inserted into the inner cavity of the arc groove. Under the action of the slider 61, the stability of the sliding connection between the handle plate 5 and the sliding hole can be guaranteed. The positioning rod 62 is fixedly connected to the top of the slider 61. Two positioning slots are respectively opened on the side of the top of the inner wall of the arc groove. The outer wall of the positioning rod 62 is slidably engaged with the inner cavity of the positioning slot. The positioning rod 62 can lock the handle plate 5, thereby ensuring the stability of the second mesh plate 4 when the handle plate 5 moves to a standstill.

[0041] Furthermore, the locking assembly 6 also includes a mounting slot, a connecting plate 63, a guide rod 64, and a support spring 65. The mounting slot is formed on the handle plate 5, which is manufactured in a two-in-one manner to facilitate the creation of the mounting slot. The connecting plate 63 is slidably disposed inside the mounting slot. The bottom of the slider 61 is fixedly connected to the connecting plate 63. The guide rod 64 is fixedly connected to the inside of the mounting slot. The outer wall of the guide rod 64 is slidably inserted and sleeved with the connecting plate 63. The support spring 65 is slidably sleeved on the outside of the guide rod 64. The support spring 65 is located at the bottom of the connecting plate 63. The support spring 65 can provide an elastic support force to the connecting plate 63, thereby enabling the support spring 65 to drive the slider 61 and the positioning rod 62 to be in a stable state and engage with the mounting sleeve 2.

[0042] Furthermore, the locking assembly 6 also includes a button 66 and a limiting post 67. The button 66 is fixedly connected to the top of the connecting plate 63. The outer wall of the button 66 is slidably inserted into the handle plate 5. Pressing down the button 66 causes the connecting plate 63 to drive the slider 61 and the positioning rod 62 to descend, causing the positioning rod 62 to separate from the positioning groove. This allows the handle plate 5 to slide in the sliding hole, thereby changing the position of the second mesh plate 4. The limiting post 67 is fixedly connected to the bottom of the inner wall of the mounting groove. The limiting post 67 is used to limit the connecting plate 63. Pressing down the button 66 causes the bottom of the connecting plate 63 to fit against the limiting post 67, which allows the slider 61 and the positioning rod 62 to separate from the sliding hole. This allows the handle plate 5 to be directly pulled out, thereby disassembling and cleaning the second mesh plate 4.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
