Description

Technical Field

[0001] The invention relates to the technical field of mineral processing and detection, and in particular to an automatic all-in-one machine for reducing concentrate samples and a reduction method. Background Art

[0002] Concentrate sample reduction is a critical step in quality testing in the mineral processing and smelting industries. Its core goal is to reduce raw ore samples to representative test samples according to standards, while ensuring an efficient and pollution-free process. With the significant increase in the number of inspection batches, sample size, and quality fluctuations at smelters, the shortcomings of traditional manual sample reduction methods in terms of efficiency, accuracy, and standardization have become increasingly prominent.

[0003] The existing technology has the following limitations:

[0004] 1. There are many manual intervention links and low efficiency

[0005] Existing fractionation solutions rely on manual labor for operations such as pouring ore samples, checking for residual ore on screens, and removing foreign matter. For example, a person must manually determine whether the screen contains residual ore sample. If so, manual intervention is required before the next step can be continued, resulting in increased processing time and difficulty meeting the timeliness requirements of raw material settlement data. Furthermore, cleaning of components such as screens and manipulators requires manual transfer to specific workstations, making process transitions dependent on manual coordination and preventing full automation.

[0006] 2. The cleaning and drying processes are separated, resulting in high contamination risk.

[0007] In existing technologies, cleaning and drying are performed in separate stages and with dispersed equipment. For example, screen cleaning must be performed manually at an inspection station, while drying relies on a separate dryer. Furthermore, the cleaning process is not synchronized with the reduction process, resulting in long periods of idle time and limited overall efficiency.

[0008] 3. Insufficient sampling flexibility and weak customization capabilities

[0009] Existing sampling manipulators typically feature fixed grippers (e.g., 1000g, 500g, etc.), which can only accommodate pre-set sample types (e.g., moisture samples, positive samples) and cannot quickly adjust the sampling volume to meet customer needs (e.g., customized storage samples, backup samples). Furthermore, the order in which different samples are gripped is fixed, lacking dynamic adjustment capabilities, making it difficult to adapt to diverse testing standards.

[0010] 4. Low automation integration and poor coordination among multiple processes

[0011] The various functional modules of existing equipment (such as screening, mixing, cleaning, and bagging) are relatively independent and rely on manual coordination or simple control systems. For example, the mixing station is separated from the sampling station, requiring manual control of the mixing time. Vacuuming and coding are also required separately after bagging, making it impossible to achieve a fully closed-loop process. Long waiting times between each process lead to insufficient equipment utilization. Summary of the Invention

[0035] The ore sample to be processed is put into the screen of the screening mechanism. The screen is located on the screening seat. The screening seat is driven by the screening seat driving device to drive the screening seat and the screen to shake to complete the screening. During the screening process, the scattering mechanism is used to properly stir and disperse the ore sample.

[0036] The sieved ore sample falls into the container, which is then driven by the first linear module to move to the bottom of the mixing mechanism;

[0037] The shell of the sample mixing mechanism descends and seals with the container to form a sample mixing container, and the stirring component mixes the ore sample;

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or implementations.

[0064] like Figures 1 to 3 and Figure 7 As shown, the embodiment of the present invention provides an automatic concentrate sample reduction integrated machine, including a machine body 100, a screening mechanism 200, a scattering mechanism 300, a container 800, a sample mixing mechanism 900, a grabbing device, a packaging and coding integrated machine 600, a cleaning device 400 and a grab bucket cleaning mechanism 700;

[0065] The screening mechanism 200, the scattering mechanism 300, the cleaning device 400, the grabbing device, the packaging and coding integrated machine 600, the grab cleaning mechanism 700, the containing container 800 and the sample mixing mechanism 900 are all arranged in the machine body 100;

[0066] The holding container 800 is driven by a first linear module mounted on the machine body 100, moving along the path of the scattering mechanism 300, the screening mechanism 200, the sample mixing mechanism 900, and the grabbing mechanism 500 to reduce and separate the ore sample. It should be noted that a tilting cylinder is mounted on the slide of the first linear module, connecting the first linear module to the holding container 800 via the tilting cylinder. This allows the holding container 800 to be tilted, facilitating unloading of the ore sample after reduction.

[0067] like Figure 4 and Figure 5 As shown, the beating mechanism 300 includes a mounting bracket 310, a first lifting cylinder 320, a movable bracket 340, a rotation driving device 330 and a plate-shaped beating member 350;

[0068] The mounting bracket 310 is slidably connected to the body 100 and driven by a movable cylinder 390. A first lifting cylinder 320 is fixed to the mounting bracket 310, and the movable bracket 340 is driven to move upward and downward by the first lifting cylinder 320. A rotation drive device 330 is mounted on the movable bracket 340. The plate-shaped whipping element 350 is rotated by the rotation drive device 330. It should be noted that the plate-shaped whipping element 350 can be made of Teflon or anti-static UPE to prevent mineral adhesion.

[0069] Furthermore, if Figure 4 and Figure 5 As shown, the screening mechanism 200 includes a frame 210, a driving cylinder, a screen 220, a screening seat 240, a screening seat driving device and two clamping cylinders 230, wherein the frame 210 is movably mounted on the inner side of the mounting bracket 310, and the frame 210 is driven to rise and fall by the driving cylinder;

[0070] The screen 220 is used to hold the mineral samples to be screened; the two clamping cylinders 230 are symmetrically arranged on both sides of the frame 210, and their telescopic ends clamp the screen 220 by telescoping. The screening seat 240 is arranged below the frame 210 and has a screen mounting position and a mineral sample outlet. The screening seat driving device is used to drive the screening seat 240 to reciprocate to realize the shaking screening of the screen 220.

[0071] Specifically, first, the screen 220 is installed in the screen installation position of the screening seat 240, and the screening seat driving device drives the screening seat 240 to rock back and forth to achieve screening of the minerals, and the screened minerals fall into the holding container 800 through the ore sample outlet at the bottom of the screening seat 240; it should be noted that the screening seat driving device can optionally use a driving motor 570 and a cam connection mechanism, and the cam is rotated and matched with the connecting rod to drive the screening seat 240 to rock back and forth (the screening seat driving device is actually a reciprocating drive technology, which is an existing technology, so it will not be repeated here).

[0072] During the screening process, to prevent agglomerated minerals from being screened, the first lifting cylinder 320 drives the movable bracket 340 downward until the plate-shaped beating element 350 enters the screen 220. The rotary drive device 330 stirs the mineral sample in the screen 220 to prevent agglomeration and facilitate subsequent cleaning of the screen 220. After the plate-shaped beating element 350 crushes the mineral sample, it is reset under the drive of the first lifting cylinder 320. The screening seat drive device continues to drive the screen 220 for screening. The above steps are repeated until the minerals completely fall into the container 800, thereby completing the preliminary screening of the minerals. The first linear module then drives the container 800 to move below the sample mixing mechanism 900 to mix the mineral samples.

[0073] After the screening is completed, the screen will be cleaned. Figure 10 and Figure 11 As shown, the screen cleaning device includes an adjusting cylinder 1130, a flushing mechanism 1110 and an air-blowing and drying mechanism 1100. The flushing mechanism 1110 and the air-blowing and drying mechanism 1100 are slidably installed on the mounting bracket 310. The mounting bracket 310 is driven to move by the moving cylinder 390. The flushing mechanism 1110 and the air-blowing and drying mechanism 1100 are driven by the adjusting cylinder 1130 to move above the screen 220 to flush and dry the screen 220.

[0074] First, the surface of the screen 220 is flushed by the flushing mechanism 1110. In this embodiment, the flushing mechanism 1110 includes a rotating nozzle 1111 and a first cover body 1112, wherein the first cover body 1112 is docked with the outer edge of the screen 220, and the rotating nozzle 1111 is connected to the external water supply system to flush the screen 220. After the flushing is completed, the regulating cylinder 1130 drives the air blast drying mechanism 1100 to move to the top of the screen 220 for docking. It should be noted that the air blast drying mechanism 1100 is connected to the output interface of the external drying system, so that the heat flow delivered by the external drying system is evenly blown to the screen 220 to dry the moisture in the screen 220.

[0075] In this embodiment, the sample mixing mechanism 900 includes a lifting device, a housing, and a stirring assembly. The stirring assembly is disposed in the housing, and the housing is driven to rise and fall by the lifting device.

[0076] When the containing container 800 moves to the bottom of the sample mixing mechanism 900, the lifting device drives the shell to descend and engage with the containing container 800 to form a closed sample mixing container, so that the stirring assembly can mix the mineral sample.

[0077] The container 800 is positioned at the sample mixing station, the lifting device lowers the shell, the shell is sealed and fitted with the edge of the container 800, the stirring component starts mixing, and after mixing, the shell rises and resets.

[0078] Furthermore, the stirring assembly comprises a drive motor 570 and a stirring rod, which is driven by the drive motor 570 to rotate and stir the ore sample. After mixing, the sample is moved to the grab bucket station, where it is separated and then transferred to the packaging and coding integrated machine 600 for packaging.

[0079] Container 800, serving as a carrier for the ore sample, is automatically transferred between workstations via linear modules. These modules work together according to a program, eliminating manual transfers, optimizing the ore flow process, and improving fractionation efficiency. After sample mixing is complete, the first linear module drives container 800 to the gripping station for pickup by a gripping device.

[0080] Combine Figure 6 and Figure 12As shown, the grabbing device includes a mounting frame 580, a cross-shaped movable bracket 590, a plurality of second linear modules and a plurality of grabbing bucket mechanisms 500. The mounting frame 580 is provided with a second lifting cylinder 560 and a driving motor 570. The cross-shaped movable bracket 590 is driven to rise and fall by the second lifting cylinder 560 and is driven to rotate by the driving motor 570. The plurality of second linear modules are arranged at the bottom of the cross-shaped movable bracket 590, and the plurality of grabbing bucket mechanisms 500 are respectively installed on the slide of the second linear module.

[0081] The grabbing device includes a cross-shaped movable bracket 590, a linear module and a grab bucket 500 of various specifications. The driving motor 570 rotates the cross-shaped movable bracket 590 to select the target grab bucket mechanism 500; the height is adjusted by the second lifting cylinder 560, and the second linear module moves the grab bucket horizontally to the container 800; the grab bucket mechanism 500 clamps the mineral sample and transfers it to the packaging station.

[0082] It should be noted that each grab mechanism 500 has a different model and can grab different volumes of ore samples, which are used to form a variety of test samples required for ore sample testing, such as 500g moisture samples or 300g storage samples according to customer needs.

[0083] The grab mechanism 500 includes a connecting bracket 510, a grab cylinder 520, and a grab 530. The connecting bracket 510 is fixed to the slide of the second linear module. The grab cylinder 520 is hinged on both sides of the connecting bracket 510. The grab 530 is connected to the end of the piston rod of the grab cylinder 520 via an articulated connector 540. The grab 530 is provided with a drying gas line interface 550 for inputting dry gas into the grab 530.

[0084] The grab buckets 530 of the multiple grab bucket mechanisms 500 have different specifications and are used to grab ore samples of different weights.

[0085] Specifically, the grab mechanism 530 opens and closes by driving the hinge 540 through the grab cylinder 520. The grab cylinder 520 extends and pushes the grab 530 to close and clamp the ore sample through the hinge 540; the grab cylinder 520 retracts and the grab 530 opens to unload.

[0086] like Figure 8 and Figure 9 As shown, the automatic reduction and separation machine for concentrate samples further includes a switching mechanism 1010, which includes a supporting bracket 1012, a drying plate 1011, and a switching cylinder 1013. The drying plate 1011 is fixed on the supporting bracket 1012, and a drying heat flow interface and a guide pipe are provided on the drying plate 1011.

[0087] The cleaning device 400 is mounted on the supporting bracket 1012 and includes a sealed shell and a guide pipe;

[0088] The supporting bracket 1012 is driven to move by switching the air cylinder 1013 so that the cleaning device 400 or the drying plate 1011 is docked with the sample mixing mechanism 900 to clean and dry the sample mixing mechanism 900.

[0089] The cleaning device 400 includes a sealed shell, a guide pipe, a cleaning brush, a driving device, a water spray pipe and a fourth lifting cylinder. The sealed shell is installed on the end of the piston rod of the fourth lifting cylinder, the guide pipe is installed on the sealed shell, the cleaning brush and the water spray pipe are installed in the sealed shell and are used to brush the sample mixing mechanism 900. The driving device is used to drive the cleaning brush and the water spray pipe to rotate, and the water spray pipe is connected to the external water supply system.

[0090] Specifically, the cleaning of the sample mixing mechanism 900 includes the following two stages:

[0091] Cleaning stage: The sealed housing of the cleaning device 400 is docked with the housing of the sample mixing mechanism via the fourth lifting cylinder. A water spray pipe is used for spray cleaning. The driving device and cleaning brush are used to clean the stirring component of the sample mixing mechanism 900. The wastewater generated by the cleaning is recovered through the diversion pipe.

[0092] Drying stage: Utilize the switching mechanism 1010 to switch to the drying tray 1011, and clean and dry it by blowing hot air for a certain period of time.

[0093] By integrating dual functions in one workstation, cleaning and drying are seamlessly connected, which improves the integration of the equipment.

[0094] It should be noted that when the containing container 800 moves to the grabbing station, the cleaning device 400 cooperates with the switching mechanism 1010 to clean the sample mixing mechanism 900 to improve the cleaning efficiency.

[0095] The grab bucket cleaning mechanism 700 includes a third lifting cylinder and a cleaning container. The cleaning container is driven to rise and fall by the third lifting cylinder, and the cleaning container is provided with a water supply pipe interface and a liquid discharge interface.

[0096] The grabbing device can drive the grabbing mechanism 500 to move into the cleaning container for cleaning.

[0097] The bucket cleaning mechanism 700 performs immersion cleaning in a cleaning container. The bucket 530 is moved to the cleaning station, and the third lifting cylinder raises the cleaning container. The bucket is immersed in the container and connected to the water supply pipe interface via the water supply pipe to perform a rinse. Wastewater is discharged from the bottom drain port, and the cleaning container is then lowered to its original position. It should be noted that the bucket 530 is equipped with a drying air line interface 550, which can be connected to an external drying system to dry the bucket 530 through the heat flow it receives.

[0098] After the sampling is completed, the first linear module turns the container 800 180° via the turning cylinder, so that the waste in the container 800 is transported out of the machine body 100 through the transport device 110 disposed inside the machine body 100 .

[0099] Furthermore, when the unloading of the container 800 is completed, it is moved to the switching mechanism 1010 through the first linear module. At this time, the container 800 is in a flipped state. The steps are the same as those for cleaning the sample mixing mechanism 900. First, the sealed shell of the cleaning device 400 is docked with the container 800 through the fourth lifting cylinder, and sprayed and cleaned through the water spray pipe. The container 800 is cleaned by the driving device and the cleaning brush, and the waste water generated by cleaning is recovered through the diversion pipe; then the switching mechanism 1010 is used to switch to the drying plate 1011, and the container 800 is dried by blowing hot air for a certain period of time.

[0100] The integrated packaging and coding machine 600 is arranged at the discharge station of the grab mechanism 500, and is used to perform at least one operation of sealing, vacuuming and online coding on the mineral samples put into the sampling bag.

[0101] The integrated packaging and coding machine 600 integrates sealing, vacuuming, and coding functions. The grab bucket 530 feeds materials into the sampling bag. The integrated packaging and coding machine 600 automatically performs heat sealing, vacuuming, and online coding (batch / time / weight and other information) to achieve accurate data management.

[0102] An embodiment of the present invention provides a method for automatically reducing a concentrate sample, which is implemented using the aforementioned all-in-one machine for automatically reducing a concentrate sample, and includes the following steps:

[0103] The ore sample to be processed is put into the screen 220 of the screening mechanism 200. The screen 220 is located on the screening seat 240. The screening seat driving device drives the screening seat 240 and the screen 220 to shake to complete the screening. During the screening process, the scattering mechanism 300 appropriately stirs and disperses the ore sample.

[0104] The sieved ore sample falls into the container 800, which is then driven by the first linear module to move to the bottom of the sample mixing mechanism 900.

[0105] The shell of the sample mixing mechanism 900 descends and seals with the container 800 to form a sample mixing container, and the stirring component mixes the ore sample;

[0106] This step is performed synchronously: when the container 800 moves away from the screening mechanism 200, the flushing mechanism 1110 and the air drying mechanism 1100 move to above the screen 220 to flush and dry the screen;

[0107] After the sample mixing is completed, the sample mixing mechanism 900 rises and resets, and the first linear module drives the container 800 to move to the grab bucket mechanism 500 station;

[0108] The grab mechanism 500 grabs mineral samples of different volumes and transfers them to the sampling bags of the packaging and coding machine 600; the packaging and coding machine 600 performs sealing, vacuuming and coding operations on the sampling bags;

[0109] The switching mechanism 1010 drives the cleaning device 400 to dock with the housing of the sample mixing mechanism 900, and after cleaning, switches to the drying plate 1011 for drying;

[0110] The cleaning device 400 and the drying tray 1011 clean and dry the container 800 after unloading;

[0111] The grab bucket mechanism 500 moves into the grab bucket cleaning mechanism 700 to complete the cleaning.

[0112] The automatic reduction method for concentrate samples in this embodiment has the same implementation method and technical effects as the above-mentioned automatic reduction machine for concentrate samples, so it will not be repeated here.

[0113] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
