Description

Technical Field

[0001] The utility model relates to an online moisture meter, belonging to the field of moisture meters. Background Art

[0002] Currently, moisture is an important indicator for evaluating the quality of agricultural products, foods, and pharmaceuticals. Moisture meters are commonly used to measure the moisture content of products and verify their quality. A moisture meter is an instrument capable of detecting the moisture content of various organic and inorganic solids, liquids, gases, and other samples. Moisture meters can be categorized by their measurement principles: physical and chemical methods. Commonly used physical methods include weight loss, distillation and demixing, and gas chromatography. Chemical methods include the Karl Fischer method and the toluene method. The International Organization for Standardization has designated the Karl Fischer method as the international standard for trace moisture measurement, and China has also adopted this method as the national standard for trace moisture measurement.

[0003] In the prior art, an online moisture meter is used in the methanol distillation process, and the online moisture meter consists of an instrument panel, a main rod, a sub-rod, a baffle, and a sampling head. Therefore, when using the online moisture meter, it is necessary to contact the inside of the detection pipe through the sampling part of the online moisture meter, so that the main rod immerses the sub-rod and the sampling head in the liquid, and then the use of the online moisture meter is completed by observing the instrument panel. During the use of the online moisture meter, the sampling head is restricted to the end of the sub-rod by the baffle, and the sampling head needs to contact the liquid when detecting the liquid. This will cause the baffle to contact the liquid before the sampling head, and the amount of liquid detected each time is different. In this way, the sampling head will not contact the liquid because the baffle contacts the liquid first, which affects the detection of the liquid. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an online moisture meter to solve the problems raised in the above background technology. The present invention can move the position of the sampling head at the position of the baffle while preventing the sampling head from detaching from the position of the baffle.

[0005] In order to achieve the above object, the utility model is implemented through the following technical solution: an online moisture meter, comprising a main rod, a dashboard fixedly provided on the top of the main rod, a disc fixedly provided on the surface of the main rod, a sub-rod fixedly connected to the bottom of the disc, three fixedly connected side plates arranged at equal intervals at the bottom of the sub-rod, and a sampling head fixedly provided on the side plates;

[0006] A circular plate is fixedly installed on the top of the surface of the side plate, a stop block is fixedly provided on the surface of the circular plate, a slot is provided inside the circular plate, an electric telescopic rod is fixedly provided inside the slot, the end of the electric telescopic rod is fixedly connected to a splint, a block is fixedly provided on the surface of the circular plate, an arc block is fixedly connected to the bottom of the block, a fixed block is fixedly connected to the side of the arc block, and a bolt is threadedly connected to the surface of the fixed block.

[0007] Furthermore, a groove is provided in the center of the circular plate, which matches the shape of the three side plates. Three staggered blocks and clamping blocks are arranged at equal intervals on the surface of the circular plate. The position of the clamping groove corresponds to the position of the block, and the shape of the splint matches the shape of the intervals between the three side plates.

[0008] Furthermore, the position where the clamping block contacts the annular plate is consistent with the surface shape of the annular plate. A symmetrical fixing block is arranged on both sides of the arc block. The end of the fixing block contacts the side plate, and the bolt passes through the fixing block and contacts the surface of the side plate.

[0009] Furthermore, an arc plate is fixedly provided on the top of the circular ring plate, an annular groove is opened in the center of the arc plate, a clamping plate is fixedly connected to the bottom surface of the auxiliary rod, a sliding rod is slidably connected to the surface of the clamping plate, a first circular slider is fixedly provided on the bottom surface of the circular disc, a second circular slider is fixedly provided on the top surface of the circular disc, and the top of the sliding rod is fixedly connected to a limiting plate.

[0010] Furthermore, the shape of the annular groove matches the shape of the bottom surface of the auxiliary rod. Four clamping plates are arranged at equal intervals at the bottom surface of the auxiliary rod. Holes are opened at the positions where the clamping plates contact the sliding rod. The bottom of the sliding rod is connected to the surface of the arc plate.

[0011] Furthermore, the top of the sliding rod passes through the first circular slider, the disc and the second circular slider at the same time, and the shape of the limiting plate is larger than that of the second circular slider.

[0012] The beneficial effects of the utility model are as follows: first, the circular plate needs to be moved along the bottom end of the side plate to the top of the side plate surface, and the position of the clamping plate corresponds to the interval between the side plates, and then the electric telescopic rod is started to push the clamping plate to contact the sampling head. At this time, the circular plate is moved, and the bottom of the sampling head protrudes from the bottom of the side plate. Then, bolts are used to pass through the fixing block to fix the position of the arc block, the clamping block and the circular plate on the surface of the side plate. In this way, the sampling head can contact the liquid to be detected before the side plate, so that the position of the sampling head can be moved at the position of the side plate, and the sampling head can be prevented from falling off from the position of the side plate under the action of the electric telescopic rod and the pushing clamping plate.

[0013] Secondly, when it is necessary to make the end of the sliding rod pass through the arc plate and contact the top of the circular plate, the limit plate can limit the end of the sliding rod from leaving the position of the disc, and the sliding rod can slide at the positions of the card plate, the first circular slider, the disc and the second circular slider. Then, when the positions of the main rod and the auxiliary rod move, the position of the sliding rod can slide synchronously at the position of the disc, so that the circular plate can be more stably placed on the surface of the side plate.

[0023] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 An arc plate 6 is fixedly provided on the top of the circular ring plate 4, and a ring groove 601 is opened in the center of the arc plate 6. The bottom surface of the auxiliary rod 202 is fixedly connected to the clamping plate 7, and the surface of the clamping plate 7 is slidably connected to the slide rod 701.

[0024] The shape of the annular groove 601 matches the bottom shape of the auxiliary rod 202. Four clamping plates 7 are evenly spaced on the bottom surface of the auxiliary rod 202. The clamping plates 7 have holes where they contact the slide rod 701. The bottom of the slide rod 701 is connected to the surface of the arc plate 6.

The shape of the limit plate 8 is larger than that of the second circular slider 703.

[0025] Specific implementation method: First, when it is necessary to prevent the side plate 3 from contacting the liquid to be detected before the sampling head 301, it is necessary to move the position of the circular plate 4 along the bottom end surface of the side plate 3 to the top of the side plate 3 surface, and at the same time make the position of the clamping plate 404 correspond to the interval between the side plates 3. Then, the electric telescopic rod 403 can be started to push the clamping plate 404 to contact the surface of the sampling head 301.

Then, the bolt 503 is used to pass through the position of the fixing block 502 to fix the arc block 501, the clamping block 5 and the circular plate 4 on the surface of the side plate 3. In this way, the sampling head 301 can contact the liquid to be detected before the side plate 3, so that the position of the sampling head 301 can be moved at the position of the side plate 3, and the sampling head 301 can be prevented from falling off from the position of the side plate 3 under the action of the electric telescopic rod 403 and the pushing clamping plate 404.

[0026] Secondly, when it is necessary to make the position of the circular plate 4 more stable on the surface of the side plate 3, it is necessary to make the end of the slide rod 701 pass through the arc plate 6 and contact the top of the circular plate 4, and then the limit plate 8 can limit the end of the slide rod 701 from leaving the position of the disc 201. At the same time, the slide rod 701 can slide at the positions of the card plate 7, the first circular slider 702, the disc 201 and the second circular slider 703. Then, when the positions of the main rod 1 and the auxiliary rod 202 are moved, the position of the slide rod 701 can slide synchronously at the position of the disc 201, so that the circular plate 4 can be more stably on the surface of the side plate 3.
