[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0029] like Figure 1-3As shown, the utility model provides a reactor sampling and testing device, including a reactor body 1, a sampling component 2 and a testing component 3; the sampling component 2 includes a pump body 21 and a sampling tube 22, one end of the sampling tube 22 penetrates into the reactor body 1, the length of the sampling tube 22 is determined according to the height of the material in the reactor body, and the bottom end of the sampling tube 22 is inserted into the upper clear liquid in the reactor body 1 for extraction, and the other end of the sampling tube 22 is connected to the liquid inlet end of the pump body 21, and the extraction is carried out through the pump body 21, and the clear liquid layer can be extracted and led into the testing component 3 as a sample for sampling and detection; the testing component It comprises a detection box 31 and a filter 32. The detection box 31 is connected to and communicates with the liquid outlet end of the pump body 21, and is used to store and detect samples. The filter 32 is arranged on the detection box 31, and is used to separate the liquid phase and the solid phase of the sample after detection. In the detection box 31, the sample is first detected, and then the detected sample is filtered and separated to separate the solid phase. The liquid phase is directly discharged for processing, and the solid phase is returned to the reactor body 1. Specifically, two conduits 3101 are arranged on the detection box 31, which are respectively used to guide the liquid phase to be discharged and guide the solid phase to be returned to the reactor body 1.

[0030] It can be understood that the pump body 21 can extract the material in the reactor body 1 through the sampling tube 22 into the detection box 31 for detection, which is convenient for sampling and detection. In addition, a filter 32 is also provided in the detection box 31. The filter 32 can filter and separate the material as a sample, separate the liquid phase and the solid phase, and respectively export them through the corresponding conduits 3101. The solid phase can be directly returned to the reactor body 1, which is convenient for sampling and detection while avoiding the loss of the solid phase.

[0031] In this embodiment, refer to Figure 2 In order to store the sample in the detection box 31 and conduct detection, the detection box 31 includes a box body 311 and a detection probe 312. A liquid inlet is opened on the top of the box body 311, and the liquid outlet end of the pump body 21 is connected to the liquid inlet. The material is pumped out by the pump body 21 and poured into the box body 311 through the liquid inlet to be stored as a sample. The detection probe 312 is plugged into the top of the box body 311 and penetrates into the interior of the box body 311. The detection probe 312 is installed by plugging, which is convenient for installation and disassembly. When the detection category needs to be changed, the detection probe 312 is replaced accordingly.

[0032] It can be understood that, according to the detection category required for the random inspection, a corresponding detection probe 312 that can detect the value or content can be installed, which is not limited to the detection of a single value or content.

[0033] In this embodiment, refer to Figure 2In order to expand the space of the box 311 for installing the filter 32 so as to facilitate the separate discharge of the liquid phase and the solid phase, an opening 3102 is opened on one side of the box 311, and an extension box 313 is arranged on the opening 3102. The filter 32 is arranged at the opening 3102 to filter the material in the box 311 and discharge the liquid phase and the solid phase respectively in the box 311 and the extension box 313.

[0034] Specifically, the two conduits 3101 are respectively arranged at the bottom of the box body 311 and the bottom of the extension box 313. The conduit 3101 at the bottom of the box body 311 is used to discharge the liquid phase, and the conduit 3101 at the bottom of the extension box 313 is used to discharge the solid phase.

[0035] For further information, see Figure 2 and Figure 3 In order to return the solid phase after filtering the liquid phase, the filter 32 includes a filter medium 321, a partition 322 and a flip mechanism 323. The flip mechanism 323 is arranged at the opening 3102. The filter medium 321 and the partition 322 form a ninety-degree angle and are both arranged at the rotating end of the flip mechanism 323. The flip mechanism 323 is used to drive the filter medium 321 and the partition 322 to rotate synchronously, and the partition 322 matches the shape of the opening 3102. A sealing strip is arranged on the periphery of the partition 322, which fits the four walls of the opening 3102 for sealing. In the initial state, the partition 322 is vertically inserted into the opening 3102 to form a closed box 311. The container can hold materials therein for detection, and at the same time, the filter medium 321 is placed horizontally on the inner side of the box body 311 as a filter part. After the detection is completed, when the conduit 3101 below the box body 311 is penetrated, the material will pass through the filter medium 321 downward, and be filtered by the filter medium 321, intercepting and filtering the solid phase, while the liquid phase flows downward and is discharged through the conduit 3101 below, and then is flipped to the right by the flipping mechanism 323 and converted into a flipped state. The filter medium 321 flips 180°, so that its upper surface is facing downward in the extension box 313, thereby pouring the intercepted solid phase downward, and the solid phase is introduced from the conduit 3101 below the extension box 313 into the reactor body 1 to return the solid phase.

[0036] It can be understood that the filter medium 321 can use porous media to intercept solid particles in the leached slurry. The media for intercepting solid particles can be filter screens, woven fabrics, porous ceramics, porous metals and other media with filtering functions, so as to filter the liquid phase and intercept the solid phase. In addition, in order to ensure the filtering effect and the enrichment and precipitation of the solid phase, the time that the sample is placed in the box 311 can be extended.

[0037] Specifically, in order to achieve the flipping driving effect, the flipping mechanism 323 includes a rotating shaft and a driving motor. The driving motor is installed on the outside of the box body 311, and the rotating shaft is arranged on the output shaft of the driving motor. One end of the rotating shaft passes through the box body 311 and extends to the inside of the box body 311. The filter medium 321 and the partition 322 are both connected to the rotating shaft, and the rotating shaft is driven to rotate by the driving motor, thereby driving the filter medium 321 and the partition 322 to rotate.

[0038] It can be understood that the driving motor can be a stepper motor to facilitate controlling the rotation angle.

[0039] Furthermore, in order to prevent the solid phase from falling off, a scraper and a hydraulic push rod can be set in the extension box 313. The scraper is embedded in the side wall of the extension box 313, and the hydraulic push rod is installed on the outside of the extension box 313. The telescopic rod passes through the extension box 313 and is connected to the scraper. The scraper is located at the bottom of the filter medium 321 in the reverse state. Under the push of the hydraulic push rod, it can be flat against the bottom of the filter medium 321 for cleaning.

[0040] In this embodiment, in order to facilitate the control of the connection and disconnection of the sampling tube 22 and the conduit 3101, the sampling tube 22 and the conduit 3101 are both provided with a solenoid valve 4.

[0041] It can be understood that in order to improve the automated operation of the device, a PLC controller can also be provided, and correspondingly, the pump body 21, the solenoid valve 4, the drive motor and the detection probe 312 are electrically connected to it, and a time-controlled switch can also be provided to set the time interval. At a time interval, the pump body 21 is controlled to open, and the solenoid valve 4 on the sampling tube 22 is opened to take samples, and then the drive motor is controlled according to the detection data of the detection probe 312 and whether the data is obtained. When the detection data is obtained, the solenoid valve 4 on the conduit 3101 for discharging the liquid phase is opened, and a period of time is allowed to allow the liquid phase to be completely discharged, and then the drive motor is started to rotate 180°, transforming from the initial state to the flipping state, and at the next time interval, it is restored to its original position to achieve the purpose of automated control.

[0042] In this embodiment, in order to facilitate the installation of the sampling component 2, a detection port 101 is opened on the top of the reactor body 1, and a mounting seat 102 is provided on the detection port 101. The sampling tube 22 is detachably connected to the mounting seat 102, so that the sampling tube 22 can be disassembled and then replaced with sampling tubes 22 of different insertion depths to meet the sampling requirements of materials at different depths.

[0043] In one embodiment, see Figure 4In order to install and remove the sampling tube 22, the shape of the sampling tube 22 is an inverted J shape, and flanges are provided at the top and outside of the sampling tube 22. The flange on the outside of the sampling tube 22 is connected to the mounting seat 102 by bolts, and the flange at the top of the sampling tube 22 is connected to the liquid inlet end of the pump body 21 by bolts.

[0044] In another embodiment, see Figure 5 In order to install and disassemble the sampling tube 22, the sampling tube 22 includes a straight tube 221 and a bent tube 222. The straight tube 221 is threadedly connected to the mounting seat 102. Flanges are provided at both ends of the bent tube 222. The flange at one end is connected to the top of the straight tube 221 by bolts, and the flange at the other end is connected to the liquid inlet end of the pump body 21 by bolts.

[0045] It can be understood that the bolts can also be equipped with nuts for connecting and installing the flange, which can be adopted according to actual conditions.

[0046] Furthermore, in order to facilitate the installation of the detection component 3, the conduit 3101 for returning the solid phase can also be connected by installing it through a flange with bolts.

[0047] The specific working process of the utility model is as follows: the filter 32 is in the initial state, the solenoid valve 4 on the sampling tube 22 is opened, and the pump body 21 is started to extract samples, the materials are extracted and introduced into the box body 311, and the detection probe 312 is used for detection. After the detection, the solenoid valve 4 on the conduit 3101 at the bottom of the box body 311 is opened first, and the sample is filtered through the filter medium 321, and the liquid phase is discharged downward through the conduit 3101, while the solid phase is intercepted, and then the filter 32 is transformed from the initial state to the flip state, and the drive motor is started to drive the shaft to rotate 180°, drive the filter medium 321 and the partition 322 to rotate, and the upper surface of the filter medium 321 is facing downward in the extension box 313, the solid phase is poured downward, and the solenoid valve 4 on the conduit at the bottom of the extension box 313 is opened, so that the solid phase is returned from the conduit 3101 at the bottom of the extension box 313 to the inside of the reactor body 1, and then the solenoid valves 4 are closed, and the filter 32 is restored to the initial state, waiting for the next sampling start.
