Description

Technical Field

[0001] This utility model relates to the field of moisture determination technology, and in particular to an online moisture determination device for mining. Background Technology

[0002] Online moisture determination in mining refers to the real-time measurement of the moisture content in ore or mineral products using online monitoring equipment during the mining, processing, or transportation of mineral resources. This process is very important in mining production because the moisture content directly affects many aspects such as ore quality, processing technology, transportation, and storage.

[0003] However, existing methods for determining the moisture content of mineral products typically employ a single approach, resulting in poor data accuracy and hindering effective moisture measurement. Therefore, those skilled in the art have developed an online moisture measuring device for mining to address the problems described in the background section. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an online moisture measuring device for mining, which solves the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an online moisture measuring device for mining, comprising: a measuring chamber, a support mounted on the upper surface of the measuring chamber, a cylinder mounted on the upper surface of the support, a connecting plate mounted at the lower end of the cylinder, a partition mounted on the lower surface of the connecting plate, a moving groove formed below the partition inside the measuring chamber, a guide rod and a screw mounted from front to back inside the moving groove, a placement plate slidably mounted on the outside of the guide rod and the screw, a near-infrared spectrometer and an infrared spectrometer mounted from left to right on the upper surface inside the measuring chamber, and a motor mounted on the outside of the measuring chamber.

[0006] As a further technical solution of this utility model, a fixing groove is provided on the upper surface of the measuring box, and the lower surface of the partition plate penetrates the interior of the fixing groove.

[0007] As a further technical solution of this utility model, the drive end of the motor is connected to one end of the screw, a bearing is provided on the inner side of the moving groove, and one end of the screw is embedded in the bearing and rotatably connected to the bearing.

[0008] As a further technical solution of this utility model, the screw is threadedly connected to the placement plate, and the guide rod is slidably connected to the placement plate.

[0009] As a further technical solution of this utility model, the fixed end of the cylinder is mounted on the upper surface of the mounting bracket, and the telescopic end of the cylinder is connected to the middle position of the upper surface of the connecting plate.

[0010] As a further technical solution of this utility model, the connecting plate and the partition are arranged in a "T" shape, and the lower surface of the partition is in contact with the lower surface of the inside of the measuring chamber.

[0011] This utility model provides an online moisture measuring device for mining, which has the following advantages compared with the prior art:

[0012] 1. This design provides an online moisture determination device for mining. The operation of a motor causes a screw to rotate inside a moving trough. During rotation, the placement plate moves inside the trough, adjusting the position of the mineral product. This allows for moisture determination of the mineral product using a near-infrared spectrometer and an infrared spectrometer, effectively improving the moisture determination result and demonstrating good practicality.

[0013] 2. The online moisture determination device for mining designed in this paper uses a cylinder to raise and lower a connecting plate. During the raising and lowering, a partition moves up and down inside the determination chamber to divide the internal space of the chamber. This avoids interference between the near-infrared spectrometer and the infrared spectrometer when determining the moisture content of mineral products, thus improving the moisture determination process.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0021] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] Please see Figure 1-4 This utility model provides a technical solution for an online moisture determination device for minerals, comprising: a determination box 1, a support 3 mounted on the upper surface of the determination box 1, a cylinder 41 mounted on the upper surface of the support 3, a connecting plate 42 mounted at the lower end of the cylinder 41, a partition 4 mounted on the lower surface of the connecting plate 42, a moving groove 24 formed inside the determination box 1 below the partition 4, a guide rod 23 and a screw 22 respectively arranged from front to back inside the moving groove 24, a placement plate 21 slidably mounted on the outside of the guide rod 23 and the screw 22, a near-infrared spectrometer 11 and an infrared spectrometer 12 respectively arranged from left to right on the upper surface inside the determination box 1, and a motor 2 mounted on the outside of the determination box 1. This setup utilizes the near-infrared spectrometer 11 and the infrared spectrometer 12 to achieve dual moisture determination of the mineral products inside the determination box 1, and the partition 4 can separate the internal space of the determination box 1, thus ensuring that the near-infrared spectrometer 11 and the infrared spectrometer 12 are not interfered with when determining the moisture of the mineral products.

[0025] like Figure 2 , Figure 3 and Figure 4As shown, a fixing groove is provided on the upper surface of the measuring chamber 1, and the lower surface of the partition 4 penetrates the interior of the fixing groove. The fixed end of the cylinder 41 is mounted on the upper surface of the bracket 3, and the telescopic end of the cylinder 41 is connected to the middle position of the upper surface of the connecting plate 42. The connecting plate 42 and the partition 4 are arranged in a "T" shape. The lower surface of the partition 4 is in contact with the lower surface of the interior of the measuring chamber 1. This arrangement uses the operation of the cylinder 41 to make the connecting plate 42 rise and fall. When rising and falling, the partition 4 will rise and fall inside the measuring chamber 1 to adjust its position, thereby achieving the purpose of dividing the interior of the measuring chamber 1 to determine the moisture content of the mineral products.

[0026] like Figure 2 and Figure 4 As shown, the drive end of the motor 2 is connected to one end of the screw 22. A bearing is provided inside the moving groove 24. One end of the screw 22 is embedded in the bearing and rotatably connected to the bearing. The screw 22 is threadedly connected to the placement plate 21, and the guide rod 23 is slidably connected to the placement plate 21. This arrangement utilizes the operation of the motor 2 to make the screw 22 rotate. When rotating, the placement plate 21 slides outside the guide rod 23 and the screw 22. In this way, the placement plate 21 can be moved inside the moving groove 24 to adjust its position, thereby enabling the determination of moisture content of mineral products through different devices. It has good practicality.

[0027] The working principle of this utility model is as follows: When using the online moisture determination device for mining, the mineral product whose moisture content needs to be determined is first placed on the placement plate 21 inside the determination box 1, and the box door is closed. The near-infrared spectrometer 11 is then turned on to irradiate the mineral product on the placement plate 21 with infrared light. The near-infrared spectrometer measures the absorption of near-infrared light by irradiating the ore sample. In the absorption band of moisture, moisture will produce specific absorption peaks for near-infrared light. By analyzing these absorption peaks, the moisture content in the ore can be estimated. After measurement by the near-infrared spectrometer 11, the moisture content is then measured by the cylinder 4. The operation of the motor 2 causes the connecting plate 42 to rise, making the partition 4 rise inside the measuring chamber 1. The motor 2 then rotates the screw 22, causing the placement plate 21 to slide outside the guide rod 23 and the screw 22. This moves the placement plate 21 inside the moving groove 24 to below the infrared spectrometer 12. After reaching the desired position, the motor 2 shuts off, and the cylinder 41 operates, causing the partition 4 to descend and divide the internal space of the measuring chamber 1. At this point, the infrared spectrometer 12 is used to determine the moisture content of the mineral product. Infrared technology is primarily based on the absorption characteristics of water molecules to infrared light. Within the infrared range, water molecules can absorb infrared light of specific wavelengths. By analyzing the absorption spectrum of the mineral product sample within these wavelength ranges, the moisture content can be calculated. The near-infrared spectrometer 11 and the infrared spectrometer 12 are existing products and will not be discussed in detail here. The electrical components used in this invention are also existing products and are powered by an external power source.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
