Abstract
Description
Technical Field
[0001] This utility model relates to the field of metallurgical production technology, and in particular to an intelligent sampling system for an online analyzer. Background Technology
[0002] In industrial production processes, especially in ore processing, real-time analysis of media such as slurry is necessary to monitor the production process. The sampling system of an online analyzer, as a crucial component for obtaining analytical samples, directly impacts the accuracy and reliability of the analytical results. Traditional online sampling systems often suffer from particle and viscous media buildup in the sampling tube during sampling. Over time, this accumulation can lead to tube blockage, affecting sampling efficiency and analytical accuracy. Existing sampling systems lack effective cleaning mechanisms or employ simplistic cleaning methods that fail to thoroughly remove buildup from the sampling tube, requiring frequent manual disassembly and cleaning. This increases operating costs and labor intensity. Inadequate or untimely cleaning severely affects the real-time nature, continuity, and accuracy of the detection data, hindering the monitoring and control of production. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides an intelligent sampling system for an online analyzer, which solves the problem that existing online analyzer sampling systems are prone to clogging and incomplete cleaning due to the adhesion of particulate matter and viscous media to the sampling tube, thus affecting sampling efficiency.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows:
[0005] An intelligent sampling system for an online analyzer includes a flow channel and slurry within the flow channel, as well as a sampling shell, a control box, and a sampling tube. The sampling shell is inserted into the flow channel, and medium flow windows are provided on both sides of the end of the sampling shell inserted into the flow channel. A sandwich layer is provided at the bottom of the sampling shell. An intelligent controller is provided in the control box. The intelligent controller is connected to a sampling controller and an ultrasonic generator through a relay group. The ultrasonic generator is connected to an ultrasonic transducer through a cable. The ultrasonic transducer is located in the sandwich layer at the bottom of the sampling shell. One end of the sampling tube is inserted into the sampling shell, and the other end of the sampling tube is connected to a sample preparation buffer bottle. A sampling pump is installed on the sampling tube, and the control terminal of the sampling pump is connected to the intelligent controller.
[0006] Furthermore, the intelligent controller is also connected to a motor driver, which is connected to a stepper motor. The stepper motor is fixedly installed inside the sampling housing. The drive linkage of the stepper motor is connected to a liquid inlet cover. The liquid inlet cover has a bottomless structure. One end of the sampling tube located inside the sampling housing is fixedly inserted into the liquid inlet cover. The liquid inlet cover can effectively prevent energy loss when the medium around the sampling tube vibrates, thereby improving cleaning efficiency.
[0007] Furthermore, a connecting flange is fitted onto the outer wall of the sampling housing, which is connected to the connection port of the flow channel via fasteners.
[0008] Compared with existing technologies, the advantages of this invention are: the ultrasonic transducer efficiently converts the electrical energy output by the ultrasonic generator into mechanical energy, thereby generating high-frequency, small-amplitude vibrations. This vibration powerfully causes the medium surrounding the sampling tube to vibrate at high frequency, forming a strong scouring force that can accurately and effectively flush away various particulate matter and sticky media adhering to the sampling tube and sampling port. The entire cleaning process requires minimal manual intervention, achieving automated cleaning and greatly avoiding the high operating costs and heavy labor intensity associated with frequent manual disassembly and cleaning.
[0009] The slurry enters the sampling housing through the media flow window. During sampling, the intelligent controller transmits a signal to the motor driver, which then controls the telescopic motor to start working. The telescopic motor drives the hydrostatic hood to sink, so that it covers the sampling port of the sampling tube. When the ultrasonic transducer works and causes the media to vibrate, the hydrostatic hood can effectively prevent the energy of the vibrating media around the sampling tube from being lost to the surrounding environment, and concentrate the vibration energy to the maximum extent around the sampling tube, which significantly improves the cleaning efficiency.
[0010] The intelligent controller controls components such as the sampling pump, ultrasonic generator, and telescopic motor through a relay group, realizing intelligent control of the system. It can automatically perform sampling and cleaning operations according to the set program, improving the system's automation level and stability.
[0011] The sampling housing is connected to the flow channel via a connecting flange, making installation convenient and the structure stable. It is suitable for flow channels of different specifications and has strong versatility. Attached Figure Description

Detailed Implementation
[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0015] An intelligent sampling system for an online analyzer includes a flow channel 1 and a slurry within the flow channel 1, as well as a sampling housing 3, a control box, and a sampling tube 4. The sampling housing 3 is inserted into the flow channel 1, and medium flow windows 14 are provided on both sides of the end of the sampling housing 3 inserted into the flow channel 1. The bottom of the sampling housing 3 is provided with a sandwich layer. The control box is provided with an intelligent controller 15. The intelligent controller 15 is connected to a sampling controller 18 and an ultrasonic generator 19 through a relay group 16. The ultrasonic generator 19 is connected to an ultrasonic transducer 5 through a cable. The ultrasonic transducer 5 is located in the sandwich layer at the bottom of the sampling housing 3. One end of the sampling tube 4 is inserted into the sampling housing 3, and the other end of the sampling tube 4 is connected to a sample preparation buffer bottle 20. A sampling pump 8 is installed on the sampling tube 4, and the control terminal of the sampling pump 8 is connected to the intelligent controller 15.
[0016] The intelligent controller 15 is also connected to a motor driver 17, which is connected to a telescopic motor 7. The telescopic motor 7 is fixedly installed inside the sampling housing 3. The drive link 13 of the telescopic motor 7 is connected to a static liquid cover 6. The static liquid cover 6 has a bottomless structure. One end of the sampling tube 4 located inside the sampling housing 3 is fixedly inserted into the static liquid cover 6.
[0017] A connecting flange 2 is fitted onto the outer wall of the sampling housing 3, and is connected to the connection port of the flow channel 1 by fasteners.
[0018] When using:
[0019] The slurry flows through the sampling housing 3 via the medium flow window 14. During sampling, the intelligent controller 15 issues a command, using a set of node signals from the relay group 16 to control the motor driver 17, thereby controlling the telescopic motor 7 to work. The telescopic motor 7 moves downward according to the program preset by the intelligent controller 15, and with the help of the drive linkage 13, it drives the sampling tube 4 and the static liquid cover 6 to sink. The sampling controller 18 controls the sampling pump 8 to take samples. The ultrasonic generator 19 is controlled by the intelligent controller 15, triggering another set of node signals from the relay group 16 to generate DC voltage and high-frequency signals at regular intervals. These signals are transmitted to the ultrasonic transducer 5 via cable, converting electrical energy into mechanical energy, causing the ultrasonic transducer 5 to generate high-frequency small-amplitude vibrations. This causes high-frequency shaking in the medium around the sampling tube 4, thereby flushing out particulate matter and sticky media attached to the sampling tube 4 and the sampling port, achieving the purpose of periodic cleaning. The static liquid cover 6 can effectively prevent energy loss during the shaking of the medium around the sampling tube 4, improving cleaning efficiency.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
