Description
Technical Field
[0001] The invention relates to the technical field of PAT material detection, and in particular to a device for realizing on-line moisture detection of a fluidized bed by utilizing the PAT technology. Background Art
[0002] PAT technology, or process analysis technology, is mainly used in the pharmaceutical and chemical industries. Its current function is to monitor and control the manufacturing process in real time, using sensors and analytical instruments to monitor key parameters in the production process (such as temperature, pressure, pH value, concentration, moisture, etc.) in real time. The implementation of PAT technology includes its application in the pharmaceutical production process, such as near-infrared spectroscopy technology, which is used to monitor the pre-treatment process of traditional Chinese medicine in real time, such as extraction, concentration, alcohol precipitation, column chromatography and other processes, as well as its combined application in formulation process optimization and process quality control, providing new methods and ideas for the evaluation and control of the consistency of pharmaceutical formulation quality. In addition, the application of PAT technology has also been extended to many aspects such as pharmaceutical research and development, production and quality management, showing its important role in improving the quality and efficiency of drugs.
[0003] In the prior art, usually only one probe is installed inside the device under test to monitor key parameters in the production process. However, a single probe often requires repeated testing to obtain overall uniform data of the internal material, and it cannot penetrate into the material for testing, resulting in long testing time. Testing only the material near the side wall will make the test data inaccurate. Summary of the invention
[0004] The present invention aims to solve the deficiencies of the prior art and to provide a device for online moisture detection of a fluidized bed using PAT technology. By adopting this scheme, multiple probes can be inserted into the interior of the material for detection. By averaging the detection data of multiple probes, key parameters in the production process can be obtained, thereby improving the detection efficiency.
[0005] The present invention is achieved through the following technical solutions:
[0006] A device for online moisture detection of a fluidized bed using PAT technology, comprising:
[0007] Fluidized bed;
[0008] A connecting plate is arranged on the inner side of the fixed side wall of the fluidized bed; the connecting plate is provided with a plurality of connecting rods, the plurality of connecting rods all extend toward the inside of the fluidized bed, and the extending ends of the connecting rods are provided with PAT probes.
[0009] Compared with the prior art, usually only one probe is installed on the inner side of the tested equipment to monitor the key parameters of the production process; but a single probe often needs repeated detection for many times to obtain the overall uniform data of the internal material, and it cannot be inserted into the material for detection, resulting in long detection time, and only the material near the side wall is tested, which will make the detection data inaccurate and other problems. The present invention provides a device for online moisture detection of a fluidized bed using PAT technology. By adopting this solution, multiple probes can be inserted into the material for detection. The key parameters of the production process can be obtained by the average value of the detection data of multiple probes, thereby improving the detection efficiency.

After the data is collected, the PAT probe transmits the data to the data analysis and processing system outside the fluidized bed through a transmission line, and the data analysis and processing system displays the data through a display after processing, which is convenient for the operator to observe and analyze and summarize. That is, in the above scheme, one PAT probe is increased to multiple, and the PAT probe is extended to multiple positions of the pharmaceutical material for detection, so as to improve the detection efficiency, and the detection accuracy can be improved by averaging the data of the detection of multiple positions.
[0010] In order to extend the PAT probe to multiple positions of the pharmaceutical material for detection and improve detection accuracy, the lengths of the several connecting rods are different.
[0011] As a distribution mode of the connecting rods, the connecting plate is circular, and a plurality of the connecting rods are evenly distributed around the connecting plate.
[0012] In order to further expand the detection range, the extending ends of the plurality of connecting rods are inclined in a direction away from the axis of the connecting plate.
[0013] In order to realize the rapid disassembly and assembly of the connecting rod, the connecting plate is provided with a plurality of sleeves in an annular direction, one end of the sleeves is fixedly connected to the connecting plate; the end of the connecting rod away from the extending end is used to be inserted into the other end of the sleeve and is detachably connected to the sleeve.
[0014] As a specific detachable connection mode, the sleeve and the end of the connecting rod inserted into the sleeve are both provided with matching transverse insertion holes, and the transverse insertion holes are used for inserting bolts.
[0015] In order to further increase the number of detection points in the material and improve the detection accuracy, a rotating motor is also provided on the outer surface of the fixed side wall of the fluidized bed. The output end of the rotating motor is provided with a rotating shaft. One end of the rotating shaft penetrates the fixed side wall of the fluidized bed and is connected to the center of the connecting plate. The rotating shaft and the fixed side wall of the fluidized bed are rotatably connected via a sealed bearing. In this solution, the connecting plate is driven to rotate around its own axis by the rotating motor, thereby driving several connecting rods and PAT probes to rotate. It only needs to rotate one circle. Within one circle, a single PAT probe can also set multiple detection points to increase the number of detection data and improve the accuracy of the average value.
[0016] In order to realize the rapid disassembly and assembly of the PAT probe, the extending end of the connecting rod is provided with an internal thread section, the internal thread section is hollow and is threadedly connected to the PAT probe.
[0017] In order to facilitate the layout of the transmission line, the outer side wall of the connecting rod is provided with a first wire groove, and one end of the first wire groove is connected to the inside of the internal thread section;
