Description

Technical Field

[0001] The present invention belongs to the field of magnetite grade determination, and particularly relates to a simple magnetite grade determination device. Background Art

[0002] When a mine is being mined, it is necessary to detect the grade of the ore. Among them, iron ore, as one of many ores, is an important raw material for iron and steel production enterprises. Natural ore is gradually separated into iron through processes such as crushing, grinding, magnetic separation, flotation, and gravity separation. Magnetic iron refers to the iron in strongly magnetic iron minerals and can be abbreviated as mFe. In geological exploration, the occupancy rate of magnetic iron in total iron in iron ore is the standard for evaluating the industrial value of iron ore deposits and classifying ore industrial types. In traditional mining, in order to know whether the ore in the mine is suitable for mining, it is often necessary to sample ores at different positions in the mine and then bring them back for grade detection, which is time-consuming and laborious. Especially for positions with a relatively high roadway roof where it is difficult for manual sampling and judgment of the presence of ore, the sampling and detection are difficult and prone to danger, etc., which is rather inconvenient. Summary of the Invention

The other end of the second assembly plate is fixedly connected to the first assembly plate through a tensile sensor. A magnet is assembled on the top of the first assembly plate on the side away from the tensile sensor. The side of the magnet away from the first assembly plate is flush with the side of the housing away from the connection hole. The side of the housing away from the connection hole is covered with a diaphragm. The compression ring is locked to the side of the housing away from the connection hole and is used for pressing and fixing the side of the diaphragm. An outer extension structure is assembled on the side of the housing away from the diaphragm. An inner extension structure is assembled on the side of the second assembly plate away from the tensile sensor. The connection hole is used for the inner extension structure to pass through.

[0011] Further, the side of the outer extension structure away from the probe is connected to a handle rod through a connector. A winding wheel is also assembled on the connector. The inner extension structure is a flexible hose. One end of the flexible hose is fixedly connected to the winding wheel, and the other end of the flexible hose is fixedly connected to the second assembly plate. The connecting wire passes through the inside of the flexible hose and is connected to the controller. The winding wheel is used for coiling the flexible hose.

Detailed implementation manners

[0043] The present invention will be further described in detail below in conjunction with the embodiments, but the implementation manners of the present invention are not limited thereto.

[0044] Embodiment 1:

[0045] As Figure 1 and Figure 2 shown, the present invention provides a simple device for measuring the grade of magnetite: its structure includes an inner extension structure 1, an outer extension structure 2, a probe 3, and a controller 4. The inner extension structure 1 and the outer extension structure 2 can be adjusted in length, and the probe 3 is electrically connected to the controller 4;

[0046] The probe 3 includes a housing 301, a pressure ring 302, a diaphragm 303, a magnet 304, a first assembly plate 305, a tensile force sensor 306, a detection assembly groove 307, a spring 308, a connecting wire 309, a connection hole 310, and a second assembly plate 311. A detection assembly groove 307 is provided at the top of the housing 301. A connection hole 310 penetrates through the bottom of the housing 301, and the connection hole 310 communicates with the detection assembly groove 307. One end of the second assembly plate 311 is fixedly connected to the housing 301 at the bottom of the detection assembly groove 307 through a spring 308. The other end of the second assembly plate 311 is fixedly connected to the first assembly plate 305 through a tensile force sensor 306. A magnet 304 is assembled on the side of the top of the first assembly plate 305 away from the tensile force sensor 306. The side of the magnet 304 away from the first assembly plate 305 is flush with the side of the housing 301 away from the connection hole 310. The side of the housing 301 away from the connection hole 310 is covered with a diaphragm 303. The pressure ring 302 is locked to the side of the housing 301 away from the connection hole 310 and is used for pressing and fixing the side of the diaphragm 303. An outer extension structure 2 is assembled on the side of the housing 301 away from the diaphragm 303. An inner extension structure 1 is assembled on the side of the second assembly plate 311 away from the tensile force sensor 306. The connection hole 310 is used for the inner extension structure 1 to pass through. The tensile force sensor 306 is connected to a controller 4 through a connecting wire 309.

[0047] Among them, the determination method is as follows: The measurement calculation formula is y = 12.31x - 10.30, where y is the iron content MFe in magnetic iron and x is the tensile force F.

[0048] First, press the probe 3 against the ore to be detected through the outer extension structure 2.

[0049] Second, pull the inner extension structure 1 to separate the magnet 304 from the adsorption of the ore.

[0050] Third, substitute the maximum tensile force value obtained by the tensile force sensor 306 into the formula y = 12.31x - 10.30 to obtain the iron content MFe in magnetic iron.

[0051] Fourth, the obtained tensile force value F and iron content MFe are judged in the following way:

[0052] When the tensile force F < 1.85 and MFe < 12.47%, the ore is regarded as surrounding rock and is not mined but treated as waste.

[0053] When 1.85 ≤ F < 2.40 and 12.47% ≤ MFe < 19.24%, the ore is regarded as off-specification ore and is not mined temporarily at present.

[0054] When 2.40 ≤ F < 4.65 and 19.24% ≤ MFe < 46.94%, the ore is regarded as an ordinary ore body and can be mined.

[0055] When the tensile force F≥4.65 and MFe≥46.94%, the ore is regarded as an ultra-high-grade ore body and can be mined.

[0056] During use, according to the detection position, adjust the lengths of the inner extension structure 1 and the outer extension structure 2. Then, through the outer extension structure 2, make the magnet 304 of the probe 3 fit with the ore to be measured. At this time, the magnet 304 that is pressed by the spring 308 and is flush with the side of the housing 301 away from the outer extension structure 2 will not be affected by factors such as gravity, which can avoid the influence of errors such as gravity on the tensile force sensor 306 and better ensure the measurement accuracy. Then, the inner extension structure 1 can be pulled to make the inner extension structure 1 drive the magnet 304 to break away from the adsorption position through the second assembly plate 311, the tensile force sensor 306, and the first assembly plate 305. At this time, the tensile force sensor 306 will obtain the tensile force value. After substituting the maximum tensile force value when breaking away from adsorption into the formula for calculation, the iron content MFe is obtained. Then, combined with the tensile force value and the determination method, the grade of the ore in the mine can be quickly obtained, realizing on-site real-time measurement and the ability to measure at different heights and positions, avoiding the inconvenience of bringing back for mining, which is convenient and fast;

[0057] The device has a simple structure, is convenient for maintenance, replacement, and carrying. At the same time, the device is equipped with a detachable and replaceable diaphragm 303 on the housing on the adsorption side of the magnet 304 and the ore, so that when the magnet 304 is adsorbed for measurement, it can better avoid the difficult cleaning and influence on subsequent measurement caused by the adsorption of sundries.

[0058] Embodiment 2:

[0060] Embodiment 3:

[0061] As Figure 4 shown, compared with the previous embodiment, the outer extension structure 2 in this embodiment is a telescopic rod, and the inner extension structure 1 is a pull rope, which is convenient for adjusting the length. At the same time, the inner extension structure 1 for pulling is more convenient for adjusting the length and can also reduce the weight of the device, and the other structures and achieved effects remain unchanged.

[0062] Embodiment 4:

[0063] As Figure 5 shown, compared with the previous embodiment, the inner extension structure 1 and the outer extension structure 2 in this embodiment are spliced by multiple combined rods;

[0064] Among them, the combined rod is a telescopic rod or a folding rod or a single fixed rod;

[0065] In use, the length can be adjusted by carrying different numbers of combined rods according to the usage environment, which is more convenient for adapting to different environments, and the other structures and achieved effects remain unchanged.

[0066] Embodiment Five:

The side of the outer extension structure 2 away from the probe 3 is connected to the handle rod 7 through a connecting member 6. A winding wheel 5 is also assembled on the connecting member 6. The inner extension structure 1 is a hose. One end of the hose is fixedly connected to the winding wheel 5, and the other end of the hose is fixedly connected to the second mounting plate 311. The connection line 309 passes through the inside of the hose and is connected to the controller 4. The winding wheel 5 is used for coiling the hose;

[0068] Among them, the hose is made of plastic.

[0069] In use, more angles can be adjusted through the folding direction of the folding rod. The combination of the inner extension structure 1 made of a hose and the winding wheel 5 is more convenient for winding and unwinding the wire rope, preventing entanglement and the like, and is convenient for measurement use in complex terrains. The other structures and achieved effects remain unchanged.
