Description

Technical Field

[0001] This utility model relates to the field of trace moisture analyzer technology, and in particular to a drying device for a trace moisture analyzer. Background Technology

[0002] Currently, the trace moisture analyzer, also known as the Karl Fischer moisture analyzer, is a detection device based on the Karl Fischer coulometric method. It is used for the precise analysis of trace moisture (ppm level) in liquid, solid and gas samples, and is widely used in fields such as power, petroleum, chemical, pharmaceutical, food and new energy.

[0003] However, when using a trace moisture analyzer to detect moisture in samples, a drying mechanism is often required to dry the external environment of the analyzer to avoid interference from external moisture on the accuracy of the test results. However, due to the structural limitations of the drying mechanism itself, it only dries the flowing air directly through heating tubes, failing to preheat and dry the air before it is transported. This results in insufficient drying of the air during rapid flow, affecting the accuracy of subsequent measurement results. Therefore, we propose a drying device for a trace moisture analyzer. Utility Model Content

[0004] The main objective of this invention is to provide a drying device for a trace moisture meter, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A drying device for a trace moisture meter includes a heat-insulating frame and a measuring instrument body. A sealing baffle is hinged to the side of the heat-insulating frame via a rotating shaft. A mounting base is slidably installed on the bottom inner side of the heat-insulating frame, and the measuring instrument body is fixedly installed on the top surface of the mounting base. A drying mechanism is provided on the side of the insulation frame, and an air guide hood is fixedly connected to the side wall of the insulation frame, and the drying mechanism and the air guide hood are connected. An exhaust fan is fixedly installed on the other side of the outside of the insulation frame.

[0006] As an optional solution to the technical solution of this application, the drying mechanism includes a breathable mesh frame and a heating rod. The side of the air guide hood away from the heat preservation frame is fixedly connected to an installation frame. The middle of the side of the installation frame is fixedly connected to a connecting pipe. The outer side of the connecting pipe is fixedly connected to a hollow frame. The middle of the side of the hollow frame away from the connecting pipe is fixedly connected to an air inlet pipe. The connecting frame is slidably installed inside the hollow frame. The breathable mesh frame is fixedly installed on the inner side of the connecting frame near the air guide hood.

[0007] As an optional solution to the technical solution of this application, a dustproof mesh frame is fixedly installed on the other side inside the connecting frame, and a movable frame is slidably installed on the outside of the connecting frame, with the inner sidewall of the movable frame and the top edge of the side of the connecting frame being fixedly connected.

[0008] As an optional solution to the technical solution of this application, both sides of the movable frame are vertically screwed with fixing bolts by threads, and the sides of the fixing bolts are threaded into the interior of the hollow frame.

[0009] As an optional solution to the technical solution of this application, heating rods are fixedly installed vertically at equal intervals inside the mounting frame, and a temperature controller is provided on the outside of the mounting frame.

[0010] As an optional solution to the technical solution of this application, the heat insulation frame has an air inlet groove on the side near the air guide hood, and the air inlet groove is connected to the side end of the air guide hood.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The drying device for a trace moisture analyzer according to the technical solution of this application, by setting an air guide hood on the outside of the insulation frame, and by connecting the mounting frame and the hollow tube to the inside of the insulation frame through the air guide hood, combined with the connecting frame set inside the insulation frame, and the air-permeable mesh frame and dustproof mesh set on both sides inside the connecting frame, allows air to flow outside the insulation frame and through the inside of the mounting frame. Before the heating tube heats and dries the air, the air flows through the dustproof mesh and air-permeable mesh frame inside the hollow frame. This can filter and remove dust and impurities mixed in the air. At the same time, combined with the water-absorbing material inside the air-permeable mesh frame, it can pre-absorb the moisture mixed in the air. This ensures that during the normal air flow, the heating tube can fully dry the moisture in the air, improve the dryness of the environment inside the insulation frame, and thus ensure the accuracy of the instrument body in detecting the moisture of the sample.

[0012] 2. The drying device for a trace moisture meter according to the technical solution of this application has a movable frame set on the outer side of the hollow frame. After the movable frame and the connecting frame are connected, the movable frame can be pulled after long-term drying use, so that the breathable mesh frame and the dustproof mesh can be moved out of the hollow frame at the same time. Then the surface of the breathable mesh frame and the dustproof mesh can be cleaned and the water-absorbing material inside can be filled and replaced, further ensuring the drying and dust removal quality of the flowing air.

[0015] like Figure 1-3 As shown, this utility model provides a technical solution: a drying device for a trace moisture meter. An exhaust fan is fixedly installed on the other side of the outer side of the insulation frame. The exhaust fan has through slots on both sides to ensure normal air flow. An air guide hood 2 is fixedly connected to the side wall of the insulation frame 1. An installation frame 21 is fixedly connected to the side of the air guide hood 2 away from the insulation frame 1. A connecting pipe 22 is fixedly connected to the middle of the side of the installation frame 21. A hollow frame 23 is fixedly connected to the outer side of the connecting pipe 22. An air inlet pipe 24 is fixedly connected to the middle of the side of the hollow frame 23 away from the connecting pipe 22. A connecting frame 25 is slidably installed inside the hollow frame 23. A breathable mesh frame 26 is fixedly installed on the inner side of the connecting frame 25 near the air guide hood 2. The breathable mesh frame 26 has a mesh shape on both sides and is filled with a highly hygroscopic fiber material. This fiber material, which has high hygroscopicity, a porous structure, and strong capillary action, can absorb moisture in the flowing air to achieve preliminary removal.

[0016] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, a dustproof mesh frame is fixedly installed on the other side inside the connecting frame 25, and a movable frame 28 is slidably installed on the outside of the connecting frame 25, with the inner side wall of the movable frame 28 and the top side of the connecting frame 25 being fixedly connected.

[0017] When it is necessary to measure the moisture content of the sample, the exhaust fan 14 is turned on by the external controller. At the same time, the exhaust fan draws out and discharges the air inside the insulation frame 1, while the outside air is transported into the hollow frame 23 through the air inlet pipe 24. During the air flow, the outside air passes through the dustproof mesh frame and the breathable mesh frame 26 in advance. Under the structural action of the dustproof mesh frame, the flowing air can be filtered and dust removed. The air then flows into the breathable mesh frame 26. Combined with the water-absorbing material filled inside the breathable mesh frame 26, the moisture mixed in with the flowing air can be absorbed, thereby pre-drying the air.

[0018] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), heating rods 3 are fixedly installed vertically at equal intervals inside the mounting frame 21. A temperature controller 31 is provided on the outside of the mounting frame 21. The temperature controller 31 and the heating rods 3 are electrically connected. Together with the temperature and humidity sensor set inside the mounting frame 21, the temperature and humidity inside the mounting frame 21 are regulated and controlled.

[0019] After the air is pre-dried, it flows synchronously into the mounting frame 21. The heating element is then activated by the temperature controller 31, heating and drying the air inside the mounting frame 21. Combined with the guiding and conveying action of the air guide hood 2, the dried air is then transported through the exhaust channel into the insulation frame 1, ensuring the air inside the insulation frame 1 remains dry. Therefore, when the moisture content inside the sample is detected using the measuring instrument 12, it will not be affected by external air moisture. In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a sealing baffle 13 is hinged to the side of the insulation frame 1 via a pivot. An installation base 11 is slidably installed on the bottom inner side of the insulation frame 1, and the measuring instrument body 12 is fixedly installed on the top surface of the installation base 11. An air inlet groove 15 is provided on the side of the insulation frame 1 near the air guide hood 2, and the air inlet groove 15 is connected to the side end of the air guide hood 2.

[0020] In some technical solutions (through Figure 1 , Figure 2 and Figure 3 As shown), both sides of the movable frame 28 are vertically screwed with fixing bolts 29 by threads, and the sides of the fixing bolts 29 are threaded into the interior of the hollow frame 23.

[0021] After the air has been dried for a long time, the fixing bolts 29 are loosened to move them away from the outside of the hollow frame 23. The movable frame 28 can then be pulled outward, causing the connecting frame 25 and the breathable mesh frame 26 and dustproof mesh 27 inside it to move. This allows the breathable mesh frame 26 and dustproof mesh 27 to move out of the hollow frame 23 at the same time. The surfaces of the breathable mesh frame 26 and dustproof mesh 27 are then cleaned, and the absorbent material inside the breathable mesh frame 26 is added or replaced.
