Description

Technical Field

[0001] The utility model relates to the field of mineral processing and testing technology, and more specifically, to an integrated automatic sample reduction machine for concentrates. Background Technology

[0002] Mineral concentrate sample reduction is a crucial step in quality testing within the mineral processing and smelting industries. Its core objective is to reduce raw ore samples into 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 quantities, and quality fluctuations at smelters, the shortcomings of traditional manual reduction methods in terms of efficiency, accuracy, and standardization have become increasingly prominent.

[0003] The existing technology has the following limitations:

[0004] 1. Numerous manual intervention steps lead to low efficiency.

[0005] Existing sample reduction solutions rely on manual operation for tasks such as ore sample pouring, screen residue inspection, and foreign object removal. For example, manual judgment is required to determine whether there is ore residue on the screen; if so, manual intervention is necessary before proceeding to the next step, leading to increased overall time consumption and making it difficult to meet the timeliness requirements of raw material settlement data. Furthermore, cleaning screens, robotic arms, and other components requires manual transfer to specific workstations, and process coordination relies on manual intervention, making full automation impossible.

[0006] 2. The washing and drying processes are separated, posing a high risk of contamination.

[0007] In existing technologies, the cleaning and drying processes are performed in separate steps with dispersed equipment. For example, screen cleaning needs to be done manually at the inspection station, while drying relies on a separate dryer. Furthermore, the cleaning process is not synchronized with the sizing process, resulting in long equipment downtime and limited overall efficiency.

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

[0009] Existing sampling robots are typically equipped with grippers of fixed specifications (such as 1000g, 500g, etc.), which can only meet the needs of preset sample types (such as moisture samples, normal samples), and cannot quickly adjust the sampling volume according to the customer's temporary needs (such as customized storage samples, spare samples). In addition, the gripping order of different samples is fixed, lacking dynamic adjustment capability, and it is difficult to adapt to diverse testing standards.

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

[0011] The existing equipment operates with relatively independent functional modules (such as screening, mixing, washing, and bagging), relying on manual or simple control systems for coordination. For example, the mixing and sampling stations are separate, requiring manual control of the mixing time, and vacuuming and coding are performed separately after bagging, making it impossible to achieve a closed-loop process. Long waiting times between processes result in insufficient equipment utilization. Utility Model Content

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0052] like Figures 1 to 3 and Figure 7 As shown, this utility model embodiment provides an automatic concentrate sample reduction and separation integrated machine, including a machine body 100, a screening mechanism 200, a dispersing mechanism 300, a holding container 800, a mixing mechanism 900, a gripping device, a packaging and coding integrated machine 600, a cleaning device 400, and a grab bucket cleaning mechanism 700.

[0053] The screening mechanism 200, the dispersing mechanism 300, the cleaning device 400, the gripping device, the integrated packaging and coding machine 600, the grab bucket cleaning mechanism 700, the holding container 800, and the mixing mechanism 900 are all installed inside the machine body 100.

[0054] The container 800 is driven by a first linear module mounted on the machine body 100, moving along the path of the dispersing mechanism 300, the screening mechanism 200, the mixing mechanism 900, and the grab mechanism 500 to reduce the mineral sample size. It should be noted that a tilting cylinder is installed on the slide of the first linear module. The first linear module is connected to the container 800 via the tilting cylinder, enabling the container 800 to be tilted, thus facilitating the unloading of the mineral sample after the reduction process.

[0055] like Figure 4 and Figure 5 As shown, the dispersing mechanism 300 includes a mounting bracket 310, a first lifting cylinder 320, a movable bracket 340, a rotary drive device 330, and a plate-shaped agitator 350;

[0056] The mounting bracket 310 is slidably connected to the machine body 100 and driven by the moving cylinder 390; the first lifting cylinder 320 is fixed on the mounting bracket 310, and the movable bracket 340 is driven to rise and fall by the first lifting cylinder 320; the rotary drive device 330 is mounted on the movable bracket 340; the plate-shaped agitator 350 is driven to rotate by the rotary drive device 330. It should be noted that the plate-shaped agitator 350 can be made of Teflon plate or anti-static UPE plate to avoid mineral adhesion.

[0057] Furthermore, such as Figure 4 and Figure 5 As shown, the screening mechanism 200 includes a frame 210, a drive cylinder, a screen 220, a screening seat 240, a screening seat drive device, and two clamping cylinders 230. The frame 210 is movably installed inside the mounting bracket 310, and the frame 210 is driven to rise and fall by the drive cylinder.

[0058] The screen 220 is used to hold the mineral sample to be screened; two clamping cylinders 230 are symmetrically arranged on both sides of the frame 210, and their telescopic ends clamp the screen 220 by telescopic movement. The screening seat 240 is located below the frame 210 and has a screen mounting position and a mineral sample outlet. The screening seat drive device is used to drive the screening seat 240 to reciprocate to realize the shaking screening of the screen 220.

[0059] Specifically, firstly, the screen 220 is installed at the screen mounting position of the screening seat 240. The screening seat 240 is driven to reciprocate by the screening seat drive device to screen the minerals. The screened minerals fall into the container 800 through the mineral sample outlet at the bottom of the screening seat 240. It should be noted that the screening seat drive device can be a drive motor 570 and a cam connection mechanism. The rotation of the cam, in conjunction with the connecting rod, drives the screening seat 240 to reciprocate (the screening seat drive device is actually a reciprocating drive technology, which is existing technology and will not be described in detail here).

[0060] During the screening process, to prevent agglomerated minerals from being unscreened, the first lifting cylinder 320 drives the movable support 340 downwards until the plate-shaped agitator 350 enters the screen 220. The rotation drive device 330 agitates the mineral sample in the screen 220 to prevent agglomeration and facilitates subsequent cleaning of the screen 220. After the plate-shaped agitator 350 crushes the mineral sample, it resets under the drive of the first lifting cylinder 320, and 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, thus achieving preliminary screening of the minerals. Then, the first linear module drives the container 800 to move below the mixing mechanism 900 to mix the mineral sample.

[0061] After screening, the screens will be cleaned. Specifically, in conjunction with... Figure 10 and Figure 11 As shown, the screen cleaning device includes an adjusting cylinder 1130, a rinsing mechanism 1110, and a blower drying mechanism 1100. The rinsing mechanism 1110 and the blower drying mechanism 1100 are slidably mounted on the mounting bracket 310. The mounting bracket 310 is driven to move by a moving cylinder 390. The rinsing mechanism 1110 and the blower drying mechanism 1100 are driven to move above the screen 220 by the adjusting cylinder 1130 to rinse and dry the screen 220.

[0062] First, the rinsing mechanism 1110 rinses the surface of the screen 220. In this embodiment, the rinsing mechanism 1110 includes a rotating nozzle 1111 and a first cover 1112. The first cover 1112 is connected to the outer edge of the screen 220, and the rotating nozzle 1111 is connected to an external water supply system to rinse the screen 220. After rinsing, the regulating cylinder 1130 drives the blower drying mechanism 1100 to move above the screen 220 to connect. It should be noted that the blower drying mechanism 1100 is connected to the output interface of an 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.

[0063] In this embodiment, the mixing mechanism 900 includes a lifting device, a housing, and a stirring assembly. The stirring assembly is disposed inside the housing, and the housing is driven to rise and fall by the lifting device.

[0064] When the container 800 moves below the mixing mechanism 900, the lifting device drives the shell to descend and engage with the container 800 to form a sealed mixing container, so that the stirring assembly can mix the mineral sample.

[0065] The container 800 is positioned at the mixing station, the lifting device lowers the shell, the shell is sealed to the edge of the container 800, the stirring assembly starts mixing, and after mixing, the shell rises back to its original position.

[0066] Furthermore, the mixing assembly consists of a drive motor 570 and a stirring rod. The drive motor 570 drives the stirring rod to rotate, thereby mixing the mineral sample. After mixing, the sample is moved to the grab bucket station, where it is divided and transferred to the packaging and coding integrated machine 600 for encapsulation.

[0067] The container 800 serves as a mineral sample carrier, and its automatic transfer between workstations is achieved through a linear module. Each module works collaboratively according to a program, eliminating manual handling, optimizing the mineral flow process, and improving the efficiency of sample reduction. After the sample is mixed, the first linear module drives the container 800 to move to the gripping station for the gripping device to grasp.

[0068] Combination Figure 6 and Figure 12 As shown, the gripping device includes a mounting frame 580, a cross-shaped movable support 590, multiple second linear modules, and multiple grabbing mechanisms 500. The mounting frame 580 is equipped with a second lifting cylinder 560 and a drive motor 570. The cross-shaped movable support 590 is driven to lift by the second lifting cylinder 560 and to rotate by the drive motor 570. Multiple second linear modules are located at the bottom of the cross-shaped movable support 590, and multiple grabbing mechanisms 500 are respectively mounted on the slides of the second linear modules.

[0069] The grabbing device includes a cross-shaped movable support 590, a linear module, and a multi-specification grab bucket 500. The drive motor 570 rotates the cross-shaped movable support 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 holding container 800. The grab bucket mechanism 500 clamps the ore sample and transfers it to the packaging station.

[0070] It should be noted that each grab bucket mechanism has a different model of 500, and the volume of the mineral sample it grabs varies, which is used to form various test samples required for mineral sample testing. For example, a 500g moisture sample or a 300g storage sample can be customized according to customer needs.

[0071] The grab mechanism 500 includes a connecting bracket 510, a grab cylinder 520, and a grab 530. The connecting bracket 510 is fixed on the slide of the second linear module. The grab cylinder 520 is hinged to both sides of the connecting bracket 510. The grab 530 is connected to the end of the piston rod of the grab cylinder 520 through a hinged connector 540. The grab 530 is provided with a drying gas interface 550 for inputting drying gas into the grab 530.

[0072] Among them, the grab buckets 530 of the multiple grab bucket mechanisms 500 are of different specifications and are used to grab mineral samples of different weights.

[0073] Specifically, the grab bucket mechanism 530 opens and closes by driving the hinge 540 through the grab bucket cylinder 520. When the grab bucket cylinder 520 extends, it pushes the grab bucket 530 to close and clamp the ore sample through the hinge 540; when the grab bucket cylinder 520 retracts, the grab bucket 530 opens to unload the material.

[0074] like Figure 8 and Figure 9 As shown, the automatic concentrate sample reduction machine also includes a switching mechanism 1010. The switching mechanism 1010 includes a support bracket 1012, a drying tray 1011, and a switching cylinder 1013. The drying tray 1011 is fixed on the support bracket 1012, and a drying heat flow interface and a guide pipe are provided on the drying tray 1011.

[0075] The cleaning device 400 is mounted on the support bracket 1012. The cleaning device 400 includes a sealed housing and a guide pipe.

[0076] The support bracket 1012 is moved by switching cylinder 1013 so that the cleaning device 400 or drying tray 1011 docks with the mixing mechanism 900 to clean and dry the mixing mechanism 900.

[0077] The cleaning device 400 includes a sealed housing, a guide pipe, a cleaning brush, a drive device, a water spray pipe, and a fourth lifting cylinder. The sealed housing is installed at the end of the piston rod of the fourth lifting cylinder, the guide pipe is installed on the sealed housing, and the cleaning brush and the water spray pipe are installed inside the sealed housing for cleaning the mixing mechanism 900. The drive device is used to drive the cleaning brush and the water spray pipe to rotate, and the water spray pipe is connected to an external water supply system.

[0078] Specifically, the cleaning of the mixed sample unit 900 includes the following two stages:

[0079] Cleaning stage: The sealed shell of the cleaning device 400 is connected to the shell of the mixing mechanism by the fourth lifting cylinder. It is sprayed and cleaned through the water spray pipe. The mixing component of the mixing mechanism 900 is cleaned by the drive device and the cleaning brush. The wastewater generated during cleaning is recycled through the guide pipe.

[0080] Drying stage: The switching mechanism 1010 is used to switch to the drying tray 1011, and the drying is achieved by blowing hot air for a certain period of time.

[0081] By integrating dual functions in one workstation, the washing and drying processes are seamlessly connected, improving the overall integration of the equipment.

[0082] It should be noted that when the container 800 moves to the gripping station, the cleaning device 400 works with the switching mechanism 1010 to clean the mixing mechanism 900 in order to improve cleaning efficiency.

[0083] The grab cleaning mechanism 700 includes a third lifting cylinder and a cleaning container. The cleaning container is driven to lift by the third lifting cylinder, and the cleaning container is equipped with a water supply pipe interface and a drain interface.

[0084] The gripping device can drive the grab bucket mechanism 500 to move into the cleaning container for cleaning.

[0085] The grab bucket cleaning mechanism 700 uses an immersion cleaning method with a cleaning container. The grab bucket 530 is moved to the cleaning station, and the third lifting cylinder raises the cleaning container. The grab bucket is immersed in the container and connected to a water supply pipe interface for rinsing. Wastewater is discharged from the bottom drain interface, and then the cleaning container is lowered back to its original position. It should be noted that because the grab bucket 530 is equipped with a drying air interface 550, it can be dried by the delivery of heat to an external drying system.

[0086] After sampling is completed, the first linear module rotates the container 800 180° using a tilting cylinder, so that the waste in the container 800 is conveyed out of the machine body 100 through the conveying device 110 located inside the machine body 100.

[0087] Furthermore, after the container 800 is unloaded, it is moved to the switching mechanism 1010 by the first linear module. At this time, the container 800 is in a flipped state. The steps are the same as those of the cleaning and mixing mechanism 900. First, the sealed shell of the cleaning device 400 is connected to the container 800 by the fourth lifting cylinder. The container is sprayed and cleaned by the water spray pipe. The container 800 is also cleaned by the drive device and the cleaning brush. The wastewater generated during cleaning is recovered through the guide pipe. Then, the switching mechanism 1010 is used to switch to the drying tray 1011. The container 800 is dried by hot air blowing for a certain period of time.

[0088] The packaging and coding integrated machine 600 is set at the discharge station of the grab bucket mechanism 500 and is used to perform at least one of the following operations on the mineral samples put into the sampling bag: sealing, vacuuming and online coding.

[0089] The Packaging and Coding Integrated Machine 600 integrates sealing, vacuuming, and coding functions. The grab bucket 530 feeds materials into the sampling bag, and the Packaging and Coding Integrated Machine 600 automatically heat-seals, vacuums, and codes online (batch / time / weight information, etc.) to achieve accurate data management.

[0090] The workflow of the above-mentioned automatic concentrate sample reduction machine includes the following steps:

[0091] The mineral 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 240 and the screen 220 are driven to shake by the screening seat driving device to complete the screening. During the screening process, the dispersing mechanism 300 appropriately stirs and disperses the mineral sample.

[0092] The sieved mineral sample falls into the container 800, and the first linear module drives the container 800 to move below the mixing mechanism 900;

[0093] The shell of the mixing mechanism 900 descends and seals with the holding container 800 to form a mixing container, and the stirring component mixes the mineral sample.

[0094] This step is performed synchronously: when the container 800 moves away from the screening mechanism 200, the rinsing mechanism 1110 and the blower drying mechanism 1100 move above the screen 220 to rinse and dry the screen;

[0095] After the mixing is completed, the mixing mechanism 900 rises and resets, and the first linear module drives the container 800 to move to the grab mechanism 500 station;

[0096] The grab bucket mechanism 500 grabs mineral samples of different volumes and transfers them into the sampling bags of the packaging and coding integrated machine 600; the packaging and coding integrated machine 600 performs sealing, vacuuming and coding operations on the sampling bags;

[0097] The switching mechanism 1010 drives the cleaning device 400 to dock with the housing of the mixing mechanism 900, and after cleaning, it switches to the drying tray 1011 for drying.

[0098] The cleaning device 400 and the drying tray 1011 clean and dry the unloaded container 800.

[0099] The grab bucket mechanism 500 moves into the grab bucket cleaning mechanism 700 to complete the cleaning.

[0100] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
