Abstract
Description
Technical Field
[0001] This utility model relates to the field of moisture determination technology, and in particular to a moisture analyzer for detecting polyether polyols. Background Technology
[0002] Polyether polyols are one of the main raw materials for the production of polyurethane. The polyether polyols used in polyurethane production have strict requirements for moisture content. High moisture content will cause gelation. Therefore, detecting the moisture content in polyether polyols is a crucial step in the process control of polyurethane production. Moisture detection requires a moisture analyzer.
[0003] In existing Karl Fischer moisture analyzers, the measuring container is usually placed directly on the heating plate on the device surface for heating during testing. Since there is no clamping mechanism on the outside of the container, the measuring container can easily fall off the moisture analyzer under external force, affecting the measuring efficiency of the moisture analyzer. At the same time, since the measuring container is made of glass, it is easily damaged when falling from the device, affecting the service life of the moisture analyzer. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing moisture analyzers where the measuring container is prone to falling off and being damaged under external force due to the lack of a clamping mechanism during testing. Therefore, this invention proposes a moisture analyzer device for detecting polyether polyols.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a moisture analyzer for detecting polyether polyols, comprising a main body, wherein a clamping mechanism is provided at one end of the upper surface of the main body;
[0006] The clamping mechanism includes a ring plate for driving. The ring plate is located at one end of the upper surface of the main body and is rotatably connected to one end of the upper surface of the ring plate. An L-shaped clamping plate for clamping is provided at the middle of the left and right ends and the middle of the rear side of the upper surface of the ring plate. A T-shaped gear column for adjusting the distance between the three L-shaped clamping plates is provided at the connection between the middle of the bottom end of the three L-shaped clamping plates and the top end of the ring plate. The three L-shaped clamping plates will form clamping cavities of different sizes when adjusted.
[0007] With the above technical solution, during clamping, the rotating ring plate drives the meshing T-shaped gear column to rotate. The T-shaped gear column drives the meshing L-shaped clamping plate to slide towards the center of the ring plate and clamp onto the outer surface of the testing container, thus clamping and fixing the testing container. This facilitates quick clamping and fixing of the testing container and helps prevent the testing container from shifting its position during the testing process or falling off the device and being damaged under the impact of external forces.
[0008] Furthermore, a detection container is clamped inside the clamping cavity. An annular toothed groove is formed in the middle of the upper surface of the ring plate. A push-pull rod is fixedly connected to one end of the front side inside the annular toothed groove. A concave adjusting toothed groove is formed in the middle of the lower surface of the L-shaped clamping plate. The outer side below the T-shaped gear column meshes with the annular toothed groove. The outer side above the T-shaped gear column meshes with the concave adjusting toothed groove. A limiting post plate is provided on the outer side below the L-shaped clamping plate. The L-shaped clamping plate and the limiting post plate are slidably connected. One end of the lower surface of the limiting post plate is fixedly connected to the upper surface of the main body.
[0009] With the above technical solution, when the ring plate rotates, the annular toothed groove inside it will simultaneously drive the lower part of the T-shaped gear column to rotate. The rotating T-shaped gear column will drive the L-shaped clamping plate fixedly connected to the outside of the concave adjusting toothed groove to slide inward to the ring plate through the meshing concave adjusting toothed groove. During the process of the L-shaped clamping plate sliding inward, the limiting column plate guides the sliding trajectory of the L-shaped clamping plate to prevent the sliding trajectory of the L-shaped clamping plate from deviating.
[0010] Furthermore, an electric telescopic rod is fixedly connected to each of the four corners of the upper surface of the main body. A placement plate is fixedly connected to the top of the electric telescopic rod. An electronic balance is provided at one end of the upper surface of the placement plate, and a concave storage cavity is provided at one end of the lower surface of the placement plate.
[0011] With the above technical solution, during testing, the electric telescopic rod drives the fixedly connected placement plate at the top to move downwards a specified distance, thereby causing the electronic balance placed above the placement plate to move downwards a specified distance. Then, the syringe for extracting the medicine is placed on the electronic balance for weight detection. After the weight is detected, the electric telescopic rod drives the placement plate upwards a specified distance to reset, thereby causing the electronic balance placed on the placement plate to move upwards and reset. When the placement plate moves downwards, the top of the testing container will be locked into the concave storage cavity opened at one end of the lower surface of the placement plate, preventing the top of the testing container from affecting the downward trend of the placement plate.
[0012] Furthermore, a display screen is provided at the other end of the upper surface of the main body, and a screw foot is rotatably connected to each of the four corners of the lower surface of the main body. The connection between the screw foot and the main body is provided with a threaded hole, and the distance between the bottom of the screw foot and the lower surface of the main body can be adjusted through the threaded hole.
[0013] With the above technical solution, during use, the screw foot can be rotated to move the screw foot a specified distance downwards from the threaded hole, thereby increasing the distance between the bottom of the screw foot and the lower surface of the main body, thus completing the height adjustment of the main body.
[0014] Furthermore, an annular rotating cavity is provided on the outer side of the ring plate. The annular rotating cavity is located in the middle of one end of the upper surface of the main body. The ring plate is rotatably connected to the middle of one end of the upper surface of the main body through the provided annular rotating cavity.
[0015] The above technical solution limits the rotation trajectory of the ring plate by the annular rotating cavity during the rotation process, which helps to prevent the ring plate from shaking during the rotation.
[0016] Furthermore, a guide bar block is fixedly connected to the side of the limiting column plate facing the lower part of the L-shaped clamp plate. The outer side of the guide bar block is provided with a guide bar groove, which is opened on the side of the concave adjusting tooth groove. The guide bar block is slidably connected to the guide bar groove.
[0017] With the above technical solution, when the L-shaped clamp plate slides, the guide groove fixedly connected to it will slide along the guide block fixedly connected to the limiting column plate to one end, which helps to prevent the L-shaped clamp plate from shifting or shaking during the sliding process.
[0018] This utility model has the following beneficial effects:
[0019] 1. In this utility model, the ring plate, T-shaped gear column, and L-shaped clamping plate are configured so that during clamping, the rotating ring plate drives the meshing T-shaped gear column to rotate. The T-shaped gear column drives the meshing L-shaped clamping plate to slide towards the center of the ring plate and clamp onto the outer surface of the testing container, thereby clamping and fixing the testing container. This facilitates quick clamping and fixing of the testing container, helps prevent the testing container from shifting its position during the testing process, and helps prevent the testing container from falling off the device and being damaged under the impact of external forces.
[0020] 2. In this utility model, the electric telescopic rod, the placement plate, and the electronic balance are configured so that during testing, the electric telescopic rod drives the placement plate, which is fixedly connected to the top, to move downwards by a specified distance, thereby causing the electronic balance placed on the placement plate to move downwards by a specified distance. Then, the syringe for drawing the medicine is placed on the electronic balance for weight detection. After the weight is detected, the electric telescopic rod drives the placement plate to move upwards by a specified distance to reset, thereby causing the electronic balance placed on the placement plate to move upwards to reset. This facilitates the adjustment of the position of the electronic balance, saves time in polyether polyol testing, and saves space in the device placement area. Attached Figure Description

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.
[0028] Reference Figure 1-4 One embodiment of this utility model is a moisture analyzer for detecting polyether polyols, comprising a main body 1, wherein a clamping mechanism is provided at one end of the upper surface of the main body 1.
[0029] The clamping mechanism includes a driving ring plate 7, which is located at one end of the upper surface of the main body 1 and is rotatably connected to one end of the upper surface of the ring plate 7. An L-shaped clamping plate 11 for clamping is provided at the middle of the left and right ends and the middle of the rear side of the upper surface of the ring plate 7. A T-shaped gear post 14 for adjusting the spacing between the three L-shaped clamping plates 11 is provided at the connection point between the middle of the bottom end of each of the three L-shaped clamping plates 11 and the top end of the ring plate 7. The three L-shaped clamping plates 11 will form clamping cavities of different sizes during adjustment, used to clamp and secure testing containers 8 of different sizes. The clamping cavity contains a testing container 8. An annular toothed groove 13 is formed in the middle of the upper surface of the ring plate 7, used to mesh and connect the ring plate 7 with the T-shaped gear post 14. A push-pull rod 9 is fixedly connected to one end of the front side inside the annular toothed groove 13, facilitating the application of pushing force to the ring plate 7 by the operator. A concave adjusting toothed groove 12 is formed in the middle of the lower surface of the L-shaped clamping plate 11. The outer side below the T-shaped gear post 14 meshes with the annular toothed groove 13, and the outer side above the T-shaped gear post 14 meshes with the concave adjusting toothed groove 12. A limiting device is provided on the outer side below the L-shaped clamping plate 11. The positioning plate 10 and the L-shaped clamping plate 11 are slidably connected to the positioning plate 10. One end of the lower surface of the positioning plate 10 is fixedly connected to the upper surface of the main body 1. The outer side of the ring plate 7 is provided with an annular rotating cavity, which is located in the middle of one end of the upper surface of the main body 1. The ring plate 7 is rotatably connected to the middle of one end of the upper surface of the main body 1 through the provided annular rotating cavity. A guide strip block is fixedly connected to the side of the positioning plate 10 facing the lower side of the L-shaped clamping plate 11. The outer side of the guide strip block is provided with a guide strip groove, which is located on the side of the concave adjusting tooth groove 12. The block is slidably connected to the guide groove to guide the sliding trajectory of the L-shaped clamping plate 11. During clamping, the ring plate 7 is rotated, and the ring plate 7 drives the meshing T-shaped gear column 14 to rotate. The T-shaped gear column 14 will drive the meshing L-shaped clamping plate 11 to slide towards the middle of the ring plate 7 and lock onto the outer surface of the detection container 8 to clamp and fix the detection container 8. This facilitates quick clamping and fixation of the detection container 8 and helps prevent the detection container from shifting its position during the detection process or falling off the device and being damaged under the impact of external forces.
[0030] An electric telescopic rod 3 is fixedly connected to each of the four corners of the upper surface of the main body 1. A placement plate 4 is fixedly connected to the top of the electric telescopic rod 3. An electronic balance 5 is provided at one end of the upper surface of the placement plate 4 for weighing the medicine. A concave storage cavity is provided at one end of the lower surface of the placement plate 4 to prevent the downward movement of the placement plate 4 from being affected. During the test, the electric telescopic rod 3 drives the placement plate 4 fixedly connected to the top to move downward a specified distance, thereby driving the electronic balance 5 placed above the placement plate 4 to move downward a specified distance. Then, the syringe for extracting the medicine is placed on the electronic balance 5 for weight detection.
[0031] The other end of the upper surface of the main body 1 is provided with a display screen 6. A screw foot 2 is rotatably connected to each of the four corners of the lower surface of the main body 1. The connection between the screw foot 2 and the main body 1 is provided with a threaded hole. The screw foot 2 can be adjusted through the threaded hole to adjust the distance between the bottom of the screw foot 2 and the lower surface of the main body 1, thereby adjusting the height of the main body 1. When adjusting the height, the screw foot 2 is rotated to move the screw foot 2 a specified distance downwards from the threaded hole, thereby increasing the distance between the bottom of the screw foot 2 and the lower surface of the main body 1, thus changing the height of the main body 1 from the workbench surface.
[0032] Working principle: In use, first rotate the screw foot 2 to move it a specified distance downwards from the threaded hole, thereby increasing the distance between the bottom of the screw foot 2 and the lower surface of the main body 1, thus adjusting the height of the main body 1. Place the detection container 8 on the heating plate located in the middle of the upper part of the ring plate 7, and then push the ring plate 7 with the push rod 9. The ring plate 7 will rotate under the push force. The rotating ring plate 7 will drive the meshing T-shaped gear column 14 to rotate through the annular tooth groove 13 on the upper surface. The rotating T-shaped gear column 14 will drive the L-shaped clamp plate 11 fixedly connected to the outside of the meshing concave adjusting tooth groove 12 to slide towards the middle of the upper part of the ring plate 7. The movement causes the inner surface of the L-shaped clamping plate 11 to clamp onto the outer surface of the testing container 8, thus fixing the testing container 8 in place. During testing, the electric telescopic rod 3 drives the placement plate 4, which is fixedly connected to the top, to move downwards by a specified distance, thereby causing the electronic balance 5 placed on the placement plate 4 to move downwards by a specified distance. Then, the syringe for extracting the reagent is placed on the electronic balance 5 for weight measurement. After the weight measurement is completed, the electric telescopic rod 3 drives the placement plate 4 to move upwards by a specified distance to reset, thereby causing the electronic balance 5 placed on the placement plate 4 to move upwards to reset. Then, the polyether polyol with the measured weight is injected into the testing container 8, and the testing container 8 is heated by a heating plate. The measured data will be displayed on the display screen 6.
[0033] 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.
