Description

Technical Field

[0001] This invention relates to the field of ore processing, and in particular to an ore processing system and method. Background Technology

[0002] Coal ore processing is a complex process aimed at transforming coal ore into usable products. Coal processing can be divided into different stages, including rough processing, fine processing, and finishing processing. Rough processing mainly involves the sorting and screening of raw coal; fine processing focuses on wet or dry separation of coal. Gangue is rock mixed with the ore extracted from underground or open-pit mines during the mining process. If this gangue is not removed, the recovery rate of raw coal will be greatly reduced. Current manual gangue sorting processes are slow and cannot handle large quantities of material. Summary of the Invention

[0003] The purpose of this invention is to provide an ore processing system and method that uses a crushing device to physically separate coal and coal gangue.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A mineral processing system includes an outer shell, a crushing barrel fixedly connected inside the outer shell, the crushing barrel having multiple filter holes, and a crushing device located inside the outer shell and inside the crushing barrel.

[0006] The crushing device includes a central shaft with two rotating frames rotatably connected to it. Each rotating frame has two sliding blocks slidably connected to it. Each sliding block is fixed to a spring between itself and the corresponding rotating frame. A crushing roller is rotatably connected between the two corresponding sliding blocks in the two rotating frames. A first rotary motor is provided between one of the rotating frames and the central shaft. The central shaft is fixed inside the outer casing.

[0007] Each slider is fixed with a rack, and each end of the central shaft is rotatably connected to an incomplete gear. Each incomplete gear is meshed with two corresponding racks, and a second rotary motor is provided between each incomplete gear and the central shaft.

[0008] A method for processing an ore includes the following steps:

[0009] Step 1: Place the ore into the crushing bin;

[0010] Step 2: Drive the first and second rotary motors to crush the coal in the ore;

[0011] Step 3: The sprayer sprays water mist;

[0012] Step 4: Extrude the coal powder into coal cakes. Attached Figure Description

[0028] like Figure 1-4 As shown:

[0029] A mineral processing system includes a housing 101, a crushing barrel 104 fixed inside the housing 101, a plurality of filter holes machined on the crushing barrel 104, a crushing device installed inside the housing 101, and the crushing barrel 104 covering the crushing device.

[0030] Coal ore is placed in the crushing barrel 104, and then the crushing device is driven to work. The crushing device squeezes and vibrates the coal ore, thereby crushing the coal in the coal ore. After the diameter of the coal powder particles is smaller than the diameter of the filter holes on the crushing barrel 104, the coal powder falls into the outer shell 101, while the harder coal gangue in the coal ore is left in the crushing barrel 104, thereby physically separating the coal gangue from the coal, so that the coal gangue can be cleanly picked out and the residual coal can be utilized.

[0031] like Figure 4 and Figure 5 As shown:

[0032] The crushing device includes a central shaft 105, two rotating frames 106 rotatably connected to the central shaft 105, two sliders 108 slidably connected on each rotating frame 106, four springs 109 fixed between the four sliders 108 and the corresponding rotating frames 106, two crushing rollers 107 rotatably connected between the two sliders 108 in the two rotating frames 106 respectively, and a first rotary motor is provided between one of the rotating frames 106 and the central shaft 105, and the central shaft 105 is fixed inside the outer casing 101.

[0033] After the coal ore is placed into the crushing barrel 104, the first rotary motor is driven to work, thereby driving the two rotating frames 106 to rotate on the central shaft 105. Each of the two rotating frames 106 has a sliding block 108 slidably connected inside, and a crushing roller 107 is rotatably connected between the two sliding blocks 108. Thus, the two rotating frames 106 drive the two crushing rollers 107 to rotate, thereby bringing the crushing rollers 107 into contact with the coal ore. This causes the crushing rollers 107 and the crushing barrel 104 to squeeze the coal ore, thereby crushing the softer coal. Each crushing roller 107 is equipped with a steel brush, which cleans the surface of the coal gangue after contact with it, further separating the coal from the coal gangue to obtain more coal powder.

[0034] Since the coal ore varies in size, the spring 109 pushes the slider 108 to move within the rotating frame 106, thereby causing the two sliders 108 to drive the crushing roller 107 between them to move, so that the crushing roller 107 can fully contact the coal ore of different sizes to squeeze the different coal ore and further obtain coal powder.

[0035] like Figure 5 As shown:

[0036] Four racks 202 are fixedly connected to four sliders 108 respectively, and two incomplete gears 201 are rotatably connected to both ends of the central shaft 105 respectively. Each incomplete gear 201 has two racks 202 on both sides that mesh with it for transmission. Each incomplete gear 201 is provided with a second rotary motor between it and the central shaft 105.

[0037] When the crushing roller 107 rotates inside the crushing barrel 104, it drives the second rotary motor to work, thereby causing the two second rotary motors to drive the two incomplete gears 201 to rotate. When the incomplete gears 201 rotate and mesh with the two racks 202, the two racks 202 move closer to each other, thereby pulling the sliders 108 fixed on the two racks 202 to move within the rotating frame 106. The two sliders 108 move closer to each other, thereby driving the two crushing rollers 107 to move closer to each other. When the incomplete gear 201 rotates to the point where it no longer meshes with the racks 202, the spring 109 pushes the corresponding slider 108 to slide within the rotating frame 106, thereby causing the slider 108 to drive the crushing roller 107 to move rapidly towards the crushing barrel 104, thereby causing the crushing roller 107 to impact the coal ore. As the incomplete gear 201 continues to rotate, the crushing roller 107 continues to repeat this process, thereby causing vibration of the coal ore, thus crushing the coal.

[0038] like Figure 1 , Figure 2 and Figure 6 As shown:

[0039] Two slide rails 203 are fixed inside the outer casing 101, and two lead screws 205 are rotatably connected to the two slide rails 203 respectively. A scraper 204 is threaded between the two lead screws 205, and a third rotary motor is provided between each lead screw 205 and the slide rail 203.

[0040] After crushing, a large amount of coal powder is obtained. The coal powder falls into the outer shell 101 through the crushing barrel 104, thereby simultaneously driving two third rotary motors to work, which in turn drives two lead screws 205 to rotate simultaneously in two slide rails 203. A scraper 204 is threaded between the two lead screws 205, thereby driving the scraper 204 to move inside the outer shell 101. During the movement, the scraper moves the coal powder inside the outer shell 101 to one side, thereby pressing the coal powder into coal cakes for easy storage and use. When the two third rotary motors reverse simultaneously, they can scrape the coal powder to the other side, thereby completely collecting the coal powder.

[0041] like Figure 2 As shown:

[0042] Two sprayers 103 are fixed inside the housing 101, and the water outlet of each sprayer 103 faces the crushing tank 104.

[0043] During the process of crushing coal into coal powder by the crushing roller 107, a large amount of dust is generated. When the coal powder reaches a certain concentration in the space, there is a risk of explosion. Therefore, two sprayers 103 are fixed to the two upper corners inside the outer shell 101, and the water outlets are oriented towards the crushing barrel 104. When the coal is crushed in the crushing barrel 104, water mist is sprayed from the water outlets to achieve the effect of dust suppression. The coal powder that is wetted gathers at the bottom of the outer shell 101 and is scraped into the forming cylinder 301 by the scraper 204. It is easier to be squeezed and formed, and after drying, it forms a coal cake.

[0044] like Figure 1 , Figure 7 and Figure 8 As shown:

[0045] Two forming cylinders 301 are fixed to the bottom of the outer shell 101, two extrusion rods 302 are slidably connected inside the forming cylinders 301, two baffles 303 are fixed to the two extrusion rods 302, and a first electric push rod is provided between each extrusion rod 302 and the forming cylinder 301.

[0046] The first electric push rod is driven to work, thereby causing the first electric push rod to slide the extrusion rod 302 inside the forming cylinder 301. This causes the extrusion rod 302 to move the baffle 303 out of the forming cylinder 301, so that the baffle 303 no longer blocks the notch on the outer shell 101. This allows the scraper 204 to push the coal powder into the notch on the outer shell 101. The coal powder then enters the forming cylinder 301 through the notch. Subsequently, the first electric push rod is driven to move in the opposite direction, causing the first electric push rod to slide the extrusion rod 302 into the forming cylinder 301, thereby extruding the coal powder in the forming cylinder 301 and completing the coal cake forming.

[0047] like Figure 7 and Figure 9 As shown:

[0048] Each forming cylinder 301 is slidably connected to two first slide rods 402, and a forming plate 401 is fixed between each two first slide rods 402. Each forming cylinder 301 is provided with two slide rails 304, and a second slide rod 407 is slidably connected in each slide rail 304. A demolding template 406 is fixed between each two second slide rods 407.

[0049] After the coal cake is extruded and formed, the two first slide rods 402 are pushed, causing them to slide on the forming cylinder 301. This causes the forming plate 401 between the two first slide rods 402 to move. At this time, the formed coal cake pushes the forming plate 401 and the demolding template 406 together, so the demolding template 406 moves with the forming plate 401. During the movement of the demolding template 406, the two second slide rods 407 fixed on the demolding template 406 slide in the two slide rails 304 respectively. When the second slide rod 407 slides to the end of the slide rail 304, the slide rail 304 blocks the second slide rod 407, so the demolding template 406 stops moving, while the forming plate 401 continues to move, thereby separating the demolding template 406 from the forming plate 401, so that the coal cake remains on the demolding template 406, which facilitates the demolding operation.

[0050] like Figure 9 As shown:

[0051] Each molding plate 401 is rotatably connected to an adjusting rod 405, and each adjusting rod 405 is threadedly connected to an adjusting plate 403. Each adjusting plate 403 is fixedly connected to multiple hole-making needles 404, and the multiple hole-making needles 404 slide on the corresponding molding plate 401 and the release plate 406.

[0052] Rotating the adjusting rod 405 causes the adjusting plate 403, which is threaded onto the adjusting rod 405, to move, thereby changing the distance between the adjusting plate 403 and the forming plate 401. Multiple hole-making needles 404 are fixedly connected to the adjusting plate 403. When the adjusting plate 403 moves, it drives the multiple hole-making needles 404 to move together, thereby changing the length of the hole-making needles 404 extending out of the forming plate 401. Thus, during coal cake forming, the extension length of the hole-making needles 404 determines the thickness of the coal cake, thereby producing coal cakes of different specifications.

[0053] like Figure 1 and Figure 4 As shown:

[0054] The discharge plate 110 is rotatably connected to the crushing barrel 104, and the door panel 102 is installed on the outer shell 101.

[0055] After the coal gangue is extracted from the coal ore, the discharge plate 110 is flipped off the crushing barrel 104, thereby opening the crushing barrel 104. At the same time, the door plate 102 on the outer shell 101 is flipped 90° and then pushed downwards, causing the door plate 102 to slide down to the bottom, so that the door plate 102 receives the discharge plate 110. At this time, the crushing device is driven to rotate, thereby transporting the coal gangue out of the crushing barrel 104.

[0056] like Figure 10 As shown:

[0057] A method for processing an ore includes the following steps:

[0058] Step 1: Place the ore into the crushing bucket 104;

[0059] Step 2: Drive the first and second rotary motors to crush the coal in the ore;

[0060] Step 3: Sprayer 103 sprays water mist;

[0061] Step 4: Extrude the coal powder into coal cakes.
