[0019] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] Figure 1 FIG. 1 is a schematic diagram of the structure of a portable high-purity quartz inclusion identification device according to an embodiment of the present invention. Figure 1 As shown, the identification device includes: a device body for magnifying and imaging quartz particles, a camera system for photographing the quartz particles magnified by the device body (the quartz particles magnified by the device body can be continuously photographed and collected), a data transmission system for uploading images photographed by the camera system, a data storage end for storing the uploaded images, and a data analysis system communicating with the data storage end in an external connection, wherein the data analysis system is used to analyze the images stored in the data storage end to determine the inclusion content and grade of high-purity quartz; The device body comprises: Base; The storage battery ( Figure 1 (not shown); A light source disposed on the base; A stage is arranged on one side of the light source, and an optical path system is arranged on the stage, and the optical path system can pass the light emitted by the light source (the propagation direction of the light after emitting the stage is as shown in FIG. Figure 1 (shown by the middle dotted line), the side of the stage away from the light source is used to place high-purity quartz particles; A grating disposed on a side of the stage away from the light source; An optical imaging system for magnifying high-purity quartz particles is arranged on a side of the light source away from the light source, and an objective lens ( Figure 1 ), the optical imaging system is provided with an eyepiece ( Figure 1(not shown); The camera system is arranged on a side of the eyepiece away from the light source, and the camera system comprises: Along the side away from the light source, there are an imaging lens, an imaging conversion device and a display device in sequence, the imaging conversion device is used to convert the content photographed by the imaging lens into an image and display it on the display device, and an adapter ring is provided between the imaging lens and the eyepiece to fix the camera system on the device body; The storage battery is used to supply power to the light source.

[0021] Specifically, the device body is a cylindrical structure with a diameter ranging from 2cm to 4cm, a height ranging from 15cm to 20cm, and a weight ranging from 300g to 500g. Since the entire identification device needs to be carried continuously in the field and to ensure good working performance, the device body can be made of light, tough and high-strength opaque materials such as aluminum alloy.

[0022] Among them, the eyepiece, objective lens, optical path system, light source and optical imaging system in the main body of the device work together to observe and identify inclusions in quartz particles placed on the stage. The magnification of the eyepiece is 5 to 10 times, the magnification of the objective lens is 10 to 20 times, the light source can be an ordinary light source or a polarized light source, and the grating is fixed.

[0023] Among them, the camera system includes an imaging lens, an imaging conversion device and a display device; the display device is arranged on the top of the recognition device (the light source is arranged at the bottom of the recognition device), the screen length ranges from 8cm to 10cm, and the width ranges from 3cm to 5cm; the imaging lens diameter ranges from 4cm to 5cm; the imaging lens is fixed above the eyepiece through an adapter ring and can be freely rotated 360° to keep the correct and appropriate position for shooting, that is: the camera system is fixed to the device body through the adapter ring; the imaging conversion device of the camera system and the device body have an overall height of less than 20cm, and are arranged between the imaging lens and the display device, and the adapter ring and the imaging conversion device (the imaging conversion device can be arranged inside a fixing device, and the fixing device can be made of metal, so that the imaging conversion device can be protected) work together to maintain the balance of the camera system. After the stage in the device body is adjusted to a suitable position for observation and video recording, the imaging lens and display device of the camera system are checked, the display device displays correct and appropriate photos, the stage is controlled to move to different positions, and the adapter ring can be rotated to move the angle of the camera system (that is, the adapter ring can drive the camera system to rotate along a fixed center point) to capture images of quartz inclusions at different coordinate positions, thereby realizing data collection, wherein the stage can move freely or move to a specified position through control instructions.

[0024] Figure 2The present invention is a system schematic diagram of a portable high-purity quartz inclusion identification device in an embodiment of the present invention. The collected quartz inclusion photos can be transmitted to the data storage end through the data transmission system, and the data analysis of the quartz inclusions can be realized by using the data analysis system. The identification device can realize this complex step with the same effect as laboratory microscope observation, and can quickly judge the quartz grade. The data transmission system uploads data by wired transmission or Bluetooth transmission. The data storage device for storing data in the data storage end is a CF card, an SD card, a flash memory card or an active hard disk. After receiving the uploaded data, the data storage end stores it in the data storage device.

[0025] The light source can be irradiated to the bottom of the quartz particles through the optical path system to provide environmental conditions for magnifying the quartz particles.

[0026] The specific implementation method of using the portable device to evaluate quartz of different quality levels is as follows: 1. Take quartz ore samples on site and crush them with a geological hammer. Pick out the quartz particles, crush and sieve them to obtain quartz sample particles with a particle size between 80 and 100 meshes. Wash the dust and dirt on the surface of the quartz particles with pure water and air-dry them. Put the quartz particles into the groove of the glass slide. The groove size is 15mm long, 15mm wide and 0.5mm deep. The quartz particles cannot overlap and must be evenly dispersed. Immerse the quartz particles in mixed oil to identify inclusions. The mixed oil used is a mixture of two or more of paraffin oil, clove oil, cedar oil and kerosene. The amount used and the type of mixed oil are determined according to the actual observation effect. After fixing the glass slide, move the stage and the camera system to capture images of high-purity quartz inclusions at different coordinate positions; 2. The camera system of the recognition device captures images of different samples and transmits them to the data analysis system for analysis. Figure 3 FIG. 1 is a schematic diagram of imaging effects of quartz of different grades in an embodiment of the present invention. Figure 3 As shown, this is the imaging effect of the recognition device for quartz of different grades. The quartz grade assessment method is as follows: Through a large number of observations of quartz ores and characteristic analyses of inclusions on the market, combined with the needs of practical applications, a set of high-purity quartz grading standards based on the proportion of transparent particles have been developed, which are divided into four grades: I, II, III, and IV. For grade I and grade II quartz, refer to industry standards or custom standards to select ore sources. In the order of the four grades I, II, III, and IV, the purity, performance, and number of transparent inclusions of quartz are assessed in descending order. The specific standards for the above four grades can be set according to actual needs and are not specifically limited here.

[0027] Four standard quartz ore samples were selected according to the specified quartz screening standards, and the above four quartz particles were rated as grade I, grade II, grade III, and grade IV through the data analysis system and formulated as standard data cards.

[0028] For example: the transparent particle standard requirements are as follows: for a single quartz particle in the field of view in the analysis system, the inclusion area ratio of the transparent quartz particle should be less than 0.25%; the inclusion area ratio of the semi-transparent quartz particle should be 0.25% to 4%; the inclusion area ratio of the non-transparent quartz particle should be more than 4%. The transparent particle ratio standards for grade I, grade II, grade III, and grade IV high-purity quartz are shown in Table 1 below.

[0029] Table 1 Classification standards

[0030] 3. From the above analysis, it can be seen that the inclusion content of grade IV quartz ore samples is relatively high, while the inclusion content of grade I, II and III quartz ore samples is obviously lower, so it is meaningful to continue the purification and processing, and mining can continue laboratory experiments. Figure 4 is an image of a grade IV quartz ore in an embodiment of the present invention, such as Figure 4 As shown in the figure, the quartz ore belongs to vein quartz type mineral, which is used as an example. The quartz ore sample is taken in the field environment, and the quartz sample particles with a particle size between 80 and 100 mesh are obtained through the above implementation method. The microscopic morphology of the inclusions is observed by using the portable device. Figure 5 As shown, Figure 5 This is a microscopic image of the IV grade quartz ore in an embodiment of the present invention. It can be seen through the eyepiece that the quartz particles contain a large number of inclusions.

[0031] The image of the sample is obtained through the camera system and transmitted to the data storage end, and the inclusion content is analyzed by the analysis system. The grade of the sample is determined based on the percentage of transparent quartz particles in the quartz ore and the percentage of opaque quartz particles in the quartz ore. The sample is identified as grade IV quartz, which has a very high inclusion content and poor mineral quality. This quartz may not be suitable for further purification and processing into high-purity quartz series products and is not suitable for high-end applications.

[0032] The portable high-purity quartz inclusion identification device in this application, taking the above embodiment as an example, can be used in the field to complete the identification of high-purity quartz inclusions in a short time, and can use a portable laptop or mobile phone to perform data analysis or the data analysis end personnel to remotely output analysis reports to achieve the assessment of the grade of high-purity quartz (that is, the data analysis system runs in the laptop or mobile phone). Moreover, since the identification process of the portable identification device is simple and fast, multiple samples can be prepared at the same time for testing, and the grades of different quartz can be compared to quickly select high-quality quartz, so as to achieve rapid field evaluation of high-purity quartz mines.

[0033] In summary, the portable high-purity quartz inclusion identification device in this application makes full use of its portable characteristics, combined with a camera system, data transmission, storage, and analysis system. It makes it possible to identify quartz inclusions and judge quartz grades in the field; moreover, the device is easy to operate, reduces the cost of manpower and material output, and the overall identification process is highly efficient, and the quartz inclusion identification and quartz grade judgment process can be completed in a relatively short time.

[0034] In a feasible embodiment, the storage battery is a lithium ion battery. Of course, other types of batteries can also be used according to actual needs and environment.

[0035] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
