Description

Technical Field

[0001] The present invention belongs to the technical field of mineral product preparation, and in particular relates to an intelligent mineral product sample preparation device. Background Art

[0002] Mineral product inspection is a general term for the multiple identification steps involved in mineral product testing, including weight inspection and quality testing. It safeguards businesses in the mineral product trade and reduces trade risks and losses. Factors such as raw material composition, mining conditions, and raw material distribution often cause variations and inhomogeneities in the grade, moisture content, and particle size of mineral products. The primary purpose of mineral sample preparation is to prepare analytical samples with uniform composition and ensure that the prepared samples conform to the quality and moisture characteristics of the evaluated object. Mineral sample preparation is technical and complex. From the perspective of mineral product inspection, if the inspection error is measured as variance, sample preparation accounts for 16%, demonstrating its importance.

[0003] The preparation of mineral samples is a key link in component analysis and quality inspection. The preparation accuracy directly affects the accuracy and reliability of subsequent test results. Traditional mineral sample preparation mostly relies on manual operation, which has problems such as low efficiency, high labor intensity, and difficult to control human errors. In the existing technology, although some semi-automatic or automatic sample preparation equipment has appeared, there are still many shortcomings: First, the loading process is prone to material accumulation and blockage, which requires manual real-time monitoring and intervention, otherwise it may cause equipment overload and damage; second, the particle size control accuracy of the crushing link is insufficient, and the particle size of the crushed ore often exceeds the preset range, affecting the uniformity and representativeness of the subsequent reduction; third, the reduction ratio adjustment flexibility of the reduction mechanism is poor, and it is difficult to fully collect the crushed ore particles, which can easily cause sample loss or reduction deviation. The overall degree of automation is low, and it is difficult to meet the needs of large-scale, high-precision mineral sample preparation. Therefore, there is an urgent need for an intelligent mineral sample preparation device to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0032] Example 1, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, an intelligent mineral sample preparation device is provided, wherein a jaw crusher 2 is installed on the upper side of the interior of a preparation box 1, a blanking plate 3 is installed at the top input end of the jaw crusher 2, a blanking port 4 is provided in the blanking plate 3, an infrared identifier 5 is installed on the top of the blanking port 4, an automatic feeding mechanism 6 is provided on the outer side of the preparation box 1, and the output end of the automatic feeding mechanism 6 is arranged on the top of the blanking port 4, a reduction mechanism 7 is installed in the preparation box 1, and the reduction mechanism 7 is movably installed on the outside of the bottom output end of the jaw crusher 2, a particle size identifier 8 is installed between the bottom output end of the jaw crusher 2 and the top input end of the reduction mechanism 7, a first collecting box 9 and a second collecting box 10 are installed on both sides of the bottom of the reduction mechanism 7 of the preparation box 1, and a PLC control box 11 is installed on one side of the preparation box 1;

[0033] The reduction mechanism 7 includes a reduction box 12, which has a first feed chute 13 in the reduction box 12, and the output end of the first feed chute 13 is arranged on the upper side of the first collecting box 9. The reduction box 12 is provided with a screening box 14 in the first feed chute 13, and a second feed chute 15 is provided in the screening box 14, and the output end of the second feed chute 15 is arranged on the upper side of the second collecting box 10. An adjusting motor 16 is installed on the outside of the reduction box 12, and the power output end of the adjusting motor 16 is connected to the first adjusting rod 17, and a first gear 18 is installed on the other side of the first adjusting rod 17, and the first gear 18 is meshed with the second gear 19, and the second gear 19 is connected to the second adjusting rod 20. The first adjusting rod 17 and the second adjusting rod 20 are both rotatably installed on both sides of the top of the screening box 14, and an adjusting plate 21 is installed on the top of the first adjusting rod 17 and the second adjusting rod 20. A motion component 22 is installed on the outside of the reduction box 12.

[0034] In this embodiment, when in use, the automatic feeding of ore is realized by the automatic feeding mechanism 6, the ore is transported to the discharge port 4 of the discharge plate 3 by the automatic feeding mechanism 6, and enters the jaw crusher 2 through the discharge port 4, and the ore is crushed by the jaw crusher 2. The crushed ore is within a particle size range, and when it falls from the bottom of the jaw crusher 2, it is detected and identified by the particle size identifier 8. If the crushed particle size range exceeds the set value, the jaw plate of the jaw crusher 2 is adjusted to meet the crushed ore within a suitable range. The granular ore falling from the jaw crusher 2 enters the reduction mechanism 7, and the adjustment is started. The regulating motor 16 drives the first regulating rod 17, the first regulating rod 17 drives the first gear 18, the first gear 18 drives the meshed second gear 19, and the second gear 19 drives the second regulating rod 20 to move, so that the first regulating rod 17 and the second regulating rod 20 synchronously drive the regulating plate 21 to rotate, thereby adjusting the opening and closing distance between the regulating plates 21 on both sides, and then controlling the reduction ratio, so that most of the granular ore falling from the jaw crusher 2 falls into the first collecting box 9 through the first discharge chute 13, while a small part of the ore enters the screening box 14 between the regulating plates 21 on both sides, and enters the second collecting box 10 through the second discharge chute 15.

[0035] Among them, the screening box 14 and the bottom output end of the jaw crusher 2 are arranged in a cross-shaped structure, and when in use, it is matched with the motion component 22 to control the reduction box 12 to move back and forth at the bottom of the jaw crusher 2, so that the screening box 14 can not only collect the ore particles output from the center of the jaw crusher 2, but also collect the ore particles on both sides of the jaw crusher 2, thereby improving the use effect.

[0036] By adding PLC, automatic control can be achieved, and the jaw crusher 2, automatic feeding mechanism 6 and reduction mechanism 7 can be opened and closed, and an infrared identifier 5 is installed at the discharge port 4. Once the discharge port 4 is overfilled with feed samples, the infrared identifier 5 can control the operating speed of the automatic feeding mechanism 6 through the PLC control box 11 after identification. When the discharge port 4 is no longer blocked by the infrared identifier 5, the automatic feeding mechanism 6 is controlled to automatically restore to the initial speed; the risk of equipment damage caused by blockage of ore samples is eliminated; and in combination with the particle size identifier 8, the crushing particle size effect of the jaw crusher 2 will directly affect the precision of subsequent sample reduction. For this reason, the crushing effect of the crushed sample is identified online by the particle size identifier 8. If the crushing particle size effect does not meet the requirements, the PLC control box 11 will automatically start the alarm function to remind the equipment maintenance personnel to reinforce and repair the jaw crusher 2 in time.

[0038] In this embodiment, when in use, the rotating wheel 26 is driven to rotate by the driving motor 25, so that the rotating wheel 26 drives the convex teeth 27 to first engage with the tooth grooves 29 on the upper side of the movable seat 28, and drives the movable seat 28 to move to one side. The moving movable seat 28 drives the reduction box 12, and the reduction box 12 drives the guide sleeve 23 to slide along the guide rod 24.
