Description

Technical Field

[0001] The invention relates to the technical field of measuring devices, in particular to an online density meter. Background Art

[0002] An online densitometer is a device used to continuously measure the concentration and density of liquids online. It can be directly used in industrial production processes. It uses advanced technology to monitor the density changes of liquids in real time and transmit the data to the control system for real-time control and adjustment of the production process.

[0003] In the prior art, tuning fork-type online densitometers are generally used in industrial production for various reasons (high precision and stability are required). However, tuning fork-type online densitometers also have some disadvantages, mainly including bubbles affecting measurement accuracy. They also require frequent maintenance because substances easily adhere to the surface of the tuning fork, resulting in measurement errors. To this end, the present invention provides an online densitometer. Summary of the Invention

[0004] The object of the present invention is to provide an online density meter to solve the problems raised in the above background technology.

Measurements are performed using the control body, connecting control components, and an external top box. If the surface of the measuring tuning fork is clogged with material and needs to be cleaned, the connecting side plate can be moved up and down. The two cleaning scrapers, pulled by the scraper springs, press against the outside of the measuring tuning fork. A small motor controls the rotation of the externally threaded roller, which in turn controls the up and down movement of the internally threaded ring, which in turn controls the up and down movement of the connecting rod, thereby controlling the up and down movement of the connecting side plate. As the connecting side plate moves up and down, the cleaning scrapers scrape away material adhering to the surface of the measuring tuning fork. Once scraping is complete, pull up the connecting side plate, causing it to engage the inside of the two protective side blocks. The cleaning scrapers are pushed against the inclined surface at the bottom of the protective bottom ring, separating the two cleaning scrapers to move along the limiting plugs, pressing against the outside of the fixed block. The topmost connecting protective block presses against the bottom of the fixed block, securing the connecting side plate and cleaning scrapers in place without interfering with the vibration measurement of the measuring tuning fork.

[0006] The top of the gear train is fixedly connected to the gear of the driven gear, and the top of the gear train is fixedly connected to the gear of the driven gear. When moving up and down, the vibration shaft will be driven to move up and down. The vibration gear at one end of the vibration shaft is pushed to rotate by the vibration gear row, causing the vibration shaft to rotate, causing the vibration disk to rotate, and causing the vibration ring on the side of the vibration disk to push the sliding frame downward, pulling the reset spring to move the sliding frame downward, causing the bottom inner shaft to move downward, causing the push-pull plate to gradually rotate downward, pushing the connecting side plates on both sides away from each other, pulling the fixed spring, and pulling the cleaning scraper ring apart through the limit plug. When the side of the vibration ring is separated from the sliding frame, the sliding frame is pulled upward by the reset spring to reset, and the two connecting side plates are pulled to reset by the fixed spring. When rotating continuously, a vibration effect will be generated to reduce bubbles on the outside of the measuring tuning fork and avoid affecting the accuracy.

[0007] The present invention provides an online density meter through improvement, which has the following improvements and advantages compared with the prior art:

[0008] First, an online density meter described in the present invention installs a control body to the outside of a storage device where online density measurement is required, and performs measurement through the control body, the connecting control component and the external top box. If there is a lot of material attached to the surface of the measuring tuning fork and it needs to be cleaned, the connecting side plate can be moved up and down, and the two cleaning scrapers are pulled tightly against the outside of the measuring tuning fork by the pulling of the scraper spring. A small motor controls the rotation of the external thread roller, controls the up and down movement of the internal thread ring, and controls the up and down movement of the connecting rod, thereby controlling the up and down movement of the connecting side plate. When the connecting side plate moves up and down, the cleaning scrapers scrape off the material attached to the surface of the measuring tuning fork. When scraping is completed, the connecting side plate is pulled up to make the connecting side plate clamped to the inner side of the two protective side blocks, so that the cleaning scrapers are pushed by the inclined surface at the bottom of the protective bottom ring, so that the two cleaning scrapers are separated to both sides, so that the cleaning scrapers move along the limiting plug column, so that the cleaning scrapers are tightly attached to the outside of the fixed card block, and the topmost connecting protective block is tightly attached to the bottom of the fixed card block, so that the connecting side plate and the cleaning scrapers are fixed as a whole, which will not hinder the vibration measurement of the measuring tuning fork.

[0009] Second: In the online density meter described in the present invention, when the connecting rod moves up and down, it will drive the vibrating shaft to move up and down. The vibrating gear at one end of the vibrating shaft is pushed to rotate by the vibrating gear row, so that the vibrating shaft rotates, the vibrating disk rotates, and the vibrating ring on the side of the vibrating disk pushes the sliding frame downward, pulling the reset spring to move the sliding frame downward, and the bottom inner shaft downward, so that the push-pull plate gradually rotates downward, pushing the connecting side plates on both sides away from each other, pulling the fixed spring, and pulling the cleaning scraper ring apart through the limiting plug column. When the side of the vibrating ring is separated from the sliding frame, the sliding frame is pulled upward by the reset spring to reset, and the two connecting side plates are pulled to reset by the fixed spring. When it rotates continuously, a vibration effect is generated, which reduces bubbles on the outside of the measuring tuning fork and avoids affecting the accuracy.

[0010] Summary: The online density meter described in the present invention has the advantages of simple structure, easy operation, cleanability and high measurement accuracy. Through the above-mentioned scraping and vibration mechanism, it can effectively remove the attached materials on the measuring surface to ensure the accuracy of the measurement results. At the same time, the design of the online density meter takes into account the needs of vibration measurement to ensure that there will be no interference with the vibration measurement after cleaning.
