Description

Technical Field

[0001] The present invention relates to the field of ore sorting, and more particularly to an ore sorting device. Background Art

[0002] Ore sorting equipment is an essential component of modern industrial production. Widely used in industries such as mining, smelting, and the chemical industry, this equipment can sort ore based on its type and quality, improving resource utilization and production efficiency. However, during operation, problems such as low efficiency and low precision inevitably arise. Therefore, improvements to ore sorting equipment are of great practical significance.

[0003] The relevant ore sorting equipment includes a vibrating feeder, and a detection mechanism, a sorting mechanism and a receiving mechanism arranged below the vibrating feeder. The vibrating feeder is used to transport ore and release the ore to other mechanisms. The detection mechanism is used to detect the type or quality of the ore. The sorting mechanism changes the track of the ore passing through according to the type or quality of the ore, so that ores of different types or qualities have different movement trajectories, ensuring that the receiving mechanism can receive ores from different movement trajectories and release or store them separately. Although the above-mentioned ore sorting equipment can implement ore sorting, the vibrating feeder used therein has the defect of uneven feeding, resulting in insufficient sorting efficiency and sorting accuracy of the ore sorting equipment.

[0004] This section is intended to provide background or context for embodiments of the present invention as recited in the claims. The description herein may include concepts that could be explored, but not necessarily concepts that have been previously conceived or explored. Therefore, unless otherwise indicated herein, the material described in this section is not prior art with respect to the specification and claims of this application and is not admitted to be prior art by inclusion in this section. Summary of the Invention

[0005] In order to solve one or more of the technical problems mentioned above, the present invention provides an ore sorting device, which uses a vibrating feeder that can release ore evenly, thereby improving the sorting efficiency and sorting accuracy of the ore sorting device.

[0006] The present invention provides an ore sorting device, which includes: a vibrating feeder, which includes a feeding part and a vibration source part connected to the feeding part and driving it to vibrate, the feeding part including a feed plate for conveying ore and feeding; a detection mechanism, which is arranged below the feeding part and is used to detect the type or quality of the ore passing through; a sorting mechanism, which is arranged below the detection mechanism and can selectively blow or strike the ore passing through according to the type or quality of the ore to ensure that at least two types or qualities of ores have independent movement trajectories; and a receiving mechanism, which is arranged below the sorting mechanism and is used to receive at least two types or qualities of ores and release or store them separately. The vibrating feeder also includes at least one distributor arranged on the feed plate and used to guide the ore to be evenly released by the feed plate.

[0007] Through the ore sorting equipment provided above, at least one distributor is added to the feeding part of the vibrating feeder, so that the feed plate of the feeding part can release the ore evenly with the help of the distributor, which is beneficial for the detection mechanism, the sorting mechanism and the receiving mechanism to complete their respective tasks more accurately, thereby improving the sorting efficiency and sorting accuracy of the ore sorting equipment.

[0008] In addition, the edge of the vibrating feeder's feed plate used to release the ore has been changed to an arc edge, which increases the density of the ore released by the feed plate in a single time, making it easy to further improve the working efficiency of the ore sorting equipment. At the same time, in order to be suitable for feeding with an arc edge, the detection mechanism, sorting mechanism and separation structure have also been adaptively adjusted and improved, ensuring that the ore sorting equipment can have higher sorting efficiency and sorting accuracy while the volume remains basically unchanged.

DETAILED DESCRIPTION

[0025] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are part of the embodiments of the present disclosure, not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0026] Figure 1 The schematic diagram of the structure of the ore sorting equipment according to the embodiment of the present invention is shown. Figure 2 The figure shows a perspective view of an ore sorting device according to an embodiment of the present invention. Figure 1 and Figure 2As shown, the ore sorting equipment includes a vibrating feeder 3, which includes a feeding part 31 and a vibration source part 32 connected to the feeding part 31. The ore sorting equipment includes a detection mechanism 4 located below the feeding part 31, a sorting mechanism 5 located below the detection mechanism 4, and a receiving mechanism 6 located below the sorting mechanism 5. The vibration source part 32 is used to generate vibration and drive the feeding part 31 to vibrate, forcing the feeding part 31 to transport and release the received ore, thereby allowing the vibrating feeder 3 to release the ore downward and ensure that the ore can pass through the detection mechanism 4, the sorting mechanism 5, and the receiving mechanism 6 in sequence. The detection mechanism 4 is used to detect the type or quality of the ore passing through. The sorting mechanism 5 can obtain the type or quality of the ore based on the detection results of the detection mechanism 4 and selectively blow or strike the ore passing through according to the type or quality of the ore to ensure that at least two types or qualities of ore have independent movement trajectories. The receiving mechanism 6 is used to receive ores of at least two types or qualities and release or store them separately.

[0027] like Figure 2 and Figure 3 As shown, the feeding part 31 includes a feed plate 311 connected to the vibration source part 32. The feed plate 311 of the feeding part 31 can convey and release ore under the action of vibration. In order to effectively improve the feeding uniformity of the vibrating feeder 3, the vibrating feeder 3 also includes at least one distributor 7 provided on the feed plate 311 and used to guide the ore to be uniformly released by the feed plate 311. At least one distributor 7 is provided in the feeding part 31 of the vibrating feeder 3, so that the feed plate 311 of the feeding part 31 can release the ore uniformly with the help of the distributor 7, so as to ensure that the detection mechanism 4, the sorting mechanism 5 and the receiving mechanism 6 can complete their respective tasks more accurately, so that the ore sorting equipment has higher sorting efficiency and sorting accuracy.

[0028] The number of distributors 7 can be one or more, but it is recommended that it is preferably multiple. As an example, Figure 3 As shown, a plurality of distributors 7 are selected, and the plurality of distributors 7 are arranged in a triangular array on the feed plate 311. When the feed plate 311 conveys ore, the distributors 7 in each row of the triangular array can evenly distribute the ore passing through the feed plate 311, thereby ensuring a more uniform release of the ore from the feed plate 311 and further improving the sorting efficiency and precision of the ore sorting equipment.

[0029] like Figure 4As shown, as an example, the distributor 7 includes a guide plate assembly 71 and a connecting assembly 72. The guide plate assembly 71 includes a left guide plate 711, a right guide plate 712, and a hinge for articulating the left and right guide plates 711, 712 and maintaining them in an "eight" shape. The connecting assembly 72 includes a first outer connecting bar 721a, a second outer connecting bar 721b, a first locking bolt 721c, a first inner connecting bar 722a, a second inner connecting bar 722b, and a second locking bolt 722c. The first outer connecting bar 721a is connected to the side of the left guide plate 711 near the right guide plate 712, and the second outer connecting bar 721b is connected to the side of the right guide plate 712 near the left guide plate 711. The first locking bolt 721c passes through the first and second outer connecting bars 721a, 721b, and is screwed into the feed plate 311. The first inner connecting bar 722a is connected to the side of the left guide plate 711 near the right guide plate 712, and the second inner connecting bar 722b is connected to the side of the right guide plate 712 near the left guide plate 711. The second locking bolt 722c passes through the first and second inner connecting bars 722a, 722b and is screwed into the feed plate 311. Thus, the first and second locking bolts 721c, 722c secure the distributor 7 to the feed plate 311.

[0030] Preferably, the through holes provided on the first outer connecting bar 721a, the first inner connecting bar 722a, the second outer connecting bar 721b, and the second inner connecting bar 722b, through which the first locking bolt 721c or the second locking bolt 722c passes, are all arc-shaped holes, and the centerline of the arc surface bisecting each arc-shaped hole coincides with the central axis of the hinge shaft. In this manner, the first locking bolt 721c and the second locking bolt 722c, with the assistance of the arc-shaped holes of the connecting bars, can adjust the angle between the left guide plate 711 and the right guide plate 712, ensuring that the distributor 7 can guide and divert ore of different specifications, making the vibrating feeder 3 suitable for uniform feeding of ore of different specifications.

[0031] Next, combine Figure 2 、 Figure 3 、 Figures 5 to 9 The vibrating feeder 3 and its supporting structure are described in detail. Figure 2 、 Figure 3As shown, the feeding section 31 also includes a barrier 312 located on the edge of the feeding plate 311 and having a release opening. The barrier 312 effectively constrains the ore from leaving the feeding plate 311 only at the release opening, allowing the ore to more accurately fall toward the detection mechanism 4, the sorting mechanism 5, and the receiving mechanism 6. The vibration source 32 includes a vibration motor or electromagnetic vibrator. The vibration motor primarily consists of an electric motor and an eccentric block mounted on the motor's rotating shaft. Driven by the motor, the eccentric block generates vibrations, thereby vibrating the feeding section 31. The electromagnetic vibrator primarily consists of an electromagnet, a return spring, and a moving block disposed between the two and connected to the return spring. When power is applied to the electromagnet, a magnetic field is generated that attracts the moving block, overcoming the pressure of the spring and drawing the moving block to one side of the electromagnet. When power is removed, the magnetic field disappears, and the pressure of the spring resets the moving block. This process repeats, and the moving block, driven by the electromagnet and spring, reciprocates (vibrates), causing the feeding section 31 to vibrate.

[0032] As an example, the edge of the feed plate 311 within the release opening is a circular arc edge, which is used to release the ore. Existing ore sorting equipment uses a belt conveyor for feeding, and the edge of the belt conveyor that releases the ore is a straight edge. Because the length of the circular arc edge is greater than the length of the straight edge at the same width, the density of ore released by the vibrating feeder 3 each time is greater than that of a belt conveyor, which can further improve the operating efficiency of the ore sorting equipment. In addition, because the vibrating feeder 3 does not require a fragile belt, the maintenance cost and frequency of the vibrating feeder 3 are lower than those of a belt conveyor.

[0033] like Figure 2 、 Figure 5 As shown, the ore sorting equipment includes a first frame 1, and a vibrating feeder 3 is disposed in the first frame 1. The first frame 1 includes at least a left frame 11, a right frame 12, a front elastic bracket 13a, and a rear elastic bracket 13b. The left frame 11 and the right frame 12 are arranged opposite each other. The front elastic bracket 13a is connected to the left frame 11 and the right frame 12, and connects and supports the feeding part 31 of the vibrating feeder 3 between the left frame 11 and the right frame 12 to ensure that the feeding part 31 can vibrate relative to the first frame 1. The rear elastic bracket 13b is connected to the left frame 11 and the right frame 12, and connects and supports the vibration source part 32 of the vibrating feeder 3 between the left frame 11 and the right frame 12 to ensure that the feeding part 31 can vibrate relative to the first frame 1.

[0034] like Figure 3 and Figure 5As shown, the front elastic support 13a includes a base beam 131 connected to the left and right frames 11 and 12, a rigid leg 132 fixed to the base beam 131, an elastic leg 133 connected to the feed portion 31 or the vibration source portion 32, and a height adjustment assembly 134 disposed between the rigid leg 132 and the elastic leg 133. Thus, the front elastic support 13a can be adjusted in height using the height adjustment assembly 134. Similarly, the rear elastic support 13b also includes a base beam 131 connected to the left and right frames 11 and 12, a rigid leg 132 fixed to the base beam 131, an elastic leg 133 connected to the feed portion 31 or the vibration source portion 32, and a height adjustment assembly 134 disposed between the rigid leg 132 and the elastic leg 133. Thus, the rear elastic support 13b can be adjusted in height using the height adjustment assembly 134. It should be noted that the installation height of the above-mentioned foundation beam 131 between the left frame 11 and the right frame 12 can be selected according to actual needs and is not limited here.

[0035] As an example, the first frame 1 may further include at least one top beam and / or at least one bottom beam. The top beam has two ends connected to the top of the left frame 11 and the top of the right frame 12, respectively, while the bottom beam has two ends connected to the bottom of the left frame 11 and the bottom of the right frame 12, respectively. Thus, the top beam and / or the bottom beam can increase the structural stability of the first frame 1.

[0036] As an example, the elastic leg 133 includes an elastic section connected to the feeding part 31 or the vibration source part 32 and a rigid section connecting the elastic section and the height adjustment component 134, see Figure 6 Among them, the elastic section is mainly composed of springs or rubber, while the rigid section is composed of steel pipes, angle irons, I-beams or steel joint structures.

[0037] In either the front elastic bracket 13a or the rear elastic bracket 13b, the height adjustment assembly 134 may include an adjustment block 1341, see Figure 3 、 Figure 6 and Figure 7The adjustment block 1341 includes a first connecting surface 1341a for connecting to the rigid leg 132, a second connecting surface 1341b opposite the first connecting surface 1341a and for connecting to the elastic leg 133, a third connecting surface 1341c for connecting to the rigid leg 132, and a fourth connecting surface 1341d opposite the third connecting surface 1341c and for connecting to the elastic leg 133. The distance between the first connecting surface 1341a and the second connecting surface 1341b is different from the distance between the third connecting surface 1341c and the fourth connecting surface 1341d, and the first connecting surface 1341a is perpendicular to the third connecting surface 1341c. The adjustment block 1341 can be used to change the height of the front elastic bracket 13a or the rear elastic bracket 13b. For example, when the distance between the first connecting surface 1341a and the second connecting surface 1341b is greater than the distance between the third connecting surface 1341c and the fourth connecting surface 1341d, if a higher front elastic bracket 13a or rear elastic bracket 13b is required, the first connecting surface 1341a and the second connecting surface 1341b of the adjustment block 1341 can be used to sequentially connect the rigid leg 132 and the elastic leg 133. If a lower front elastic bracket 13a or rear elastic bracket 13b is required, the third connecting surface 1341c and the fourth connecting surface 1341d of the adjustment block 1341 can be used to sequentially connect the rigid leg 132 and the elastic leg 133. In a preferred embodiment, the connection between the adjustment block 1341 and the rigid leg 132 and the connection between the adjustment block 1341 and the elastic leg 133 are both bolted or snap-fit ​​connections.

[0038] In order to adjust the left-right and front-back positions of the feeding portion 31 and the vibration source portion 32, two examples are provided. As a preferred example, the connection between the base beam 131 and the rigid leg 132 is a bolt connection, the bolt hole formed on the base beam 131 for bolt connection is a first waist-shaped hole, and the bolt hole formed on the rigid leg 132 for bolt connection is a second waist-shaped hole, one of the first waist-shaped hole and the second waist-shaped hole extending along the front-back direction of the first frame 1, and the other extending along the left-right direction of the first frame 1. As another preferred example, the connection between the base beam 131 and the rigid leg 132 is a bolt connection, the base beam 131 is provided with a first hole group for bolt connection, and the rigid leg 132 is provided with a second hole group for bolt connection, wherein one of the first hole group and the second hole group includes a plurality of first holes spaced apart along the front-back direction of the first frame, and the other includes a plurality of second holes spaced apart along the left-right direction of the first frame.

[0039] like Figure 3 、 Figure 6 and Figure 8As shown, the height adjustment assembly 134 also includes a plurality of height adjustment shims 1342 of varying thicknesses. Some height adjustment shims 1342 are installed between the adjustment block 1341 and the rigid leg 132, or between the adjustment block 1341 and the elastic leg 133. Other height adjustment shims 1342 are mounted on the first frame 1 as spares. The use and quantity of height adjustment shims 1342 can effectively adjust the height of the front elastic bracket 13a or the rear elastic bracket 13b.

[0040] return Figure 2 and Figure 5 , the first frame 1 may also include a calibration beam 14, one end of which is detachably connected to the left frame 11, and the other end of which is detachably connected to the right frame 12. The connection between the calibration beam 14 and the left frame 11 may be a bolt connection, a lock connection, etc., and the connection between the calibration beam 14 and the right frame 12 may also be a bolt connection, a lock connection, etc. The calibration beam 14 is also detachably connected to the enclosure 312 of the feeding part 31, and the detachable connection may be a bolt connection, a lock connection, etc., and it is recommended that a more reliable bolt connection be preferred. The calibration beam 14 can accurately lock the feeding part 31 in the expected position within the first frame 1. On the one hand, it can improve the assembly quality of the vibrating feeder 3 and the accuracy of the feeding position. On the other hand, it can prevent the feeding part 31 from generating strong vibrations during transportation and causing serious damage to the front elastic bracket 13a. It is worth noting that the calibration beam 14 needs to be dismantled before the ore sorting equipment is officially used, or adjusted to a position that does not interfere with the operation of the equipment.

[0041] See also Figure 2 and Figure 5 As shown, the ore sorting equipment also includes a limit rod 8 that is arranged between the left frame 11 and the right frame 12 and is detachably connected to the left frame 11 and the right frame 12. The detachable connection can be optionally a bolt connection or a lock connection. The limit rod 8 is configured to abut against the vibration source part 32 when it is connected to the left frame 11 and the right frame 12, and to apply top-down pressure to the feeding part 31 to prevent the vibration source part 32 from generating strong vibrations during transportation and causing serious damage to the rear elastic bracket 13b. It is worth noting that the limit rod 8 needs to be removed before the ore sorting equipment is officially used, or adjusted to a position that does not interfere with the operation of the equipment.

[0042] like Figure 2 and Figure 9As shown, the feeding section 31 may also include a vibration transmission frame 33, a left vibration transmission beam 34, and a right vibration transmission beam 35. The vibration transmission frame 33 is fixed to the bottom of the feed plate 311 and is mounted outside the detection mechanism 4 with a gap. The left vibration transmission beam 34 is fixed to the bottom of the feed plate 311 and connects the vibration transmission frame 33 with the vibration source 32. The right vibration transmission beam 35 is fixed to the bottom of the feed plate 311 and connects the vibration transmission frame 33 with the vibration source 32. In the prior art, the vibration source 32 can only transmit vibration to the feeding section 31 via the left vibration transmission beam 34 and the right vibration transmission beam 35. However, this embodiment adds a vibration transmission frame 33 and mounts it outside the detection mechanism 4. This ensures that the feeding section 31 can better receive the vibration transmitted by the vibration source 32 and implement more uniform feeding without increasing the overall volume, especially the height, of the ore sorting equipment.

[0043] The detection mechanism 4 mentioned above can be selected as a camera or an X-ray detection mechanism. Figure 1 、 Figure 2 and Figure 10 As shown, the detection mechanism 4 is selected as an X-ray detection mechanism, which includes a transmitter 41, a receiver 42 and a feed space 43 formed between the transmitter 41 and the receiver 42. The transmitter 41 includes at least one transmitting source 411, and the receiver 42 includes a plurality of receiving sources 421. When the ore from the vibrating feeder 3 passes through the feed space 43, at least one transmitting source 411 is used to emit fan-shaped distributed X-rays to the receiver 42, and the plurality of receiving sources 421 are all used to receive the X-rays and generate information for detecting the type or quality of the ore based on the X-rays passing through the ore. In this example, the feed space 43 is preferably an arc gap, and the surface of the transmitter 41 facing the arc gap is the first arc surface 412, and the surface of the receiver 42 facing the arc gap is the second arc surface 422. The center lines of the first arc surface 412 and the second arc surface 422 both coincide with the reference line L, which is a selected straight line passing through the center of the arc edge 311a and perpendicular to the feed plate 311, see Figure 2 and Figure 3 In this way, the relative distance between the first arc surface 412 and the second arc surface 422 is constant, ensuring that the time for each X-ray in the laser to travel from the emitter 41 to the receiver 42 is the same. Therefore, when each X-ray passes through different ores, the imaging time of each ores is the same, thereby improving the ore sorting accuracy and sorting effect.

[0044] The above-mentioned sorting mechanism 5 can be selected as a blowing mechanism or a pushing mechanism, etc. The specific selection needs to be determined according to the actual ore. For example, when the actual ore is large in volume and heavy in weight, it is recommended to select the sorting mechanism 5 as a pushing mechanism. On the contrary, if the actual ore is small in volume and light in weight, it is recommended to select the sorting mechanism 5 as a blowing mechanism. Figure 2 and Figure 11 The blowing mechanism is described in detail. Figure 2 and Figure 11 As shown, the sorting mechanism 5 is selected as a blowing mechanism, which includes a valve block 51 and a valve assembly. The valve block 51 is a fan-shaped cylinder and includes a plurality of air injection holes 51a provided on its outer peripheral surface and spaced circumferentially. The valve assembly includes a plurality of solenoid valves 52, which are configured to independently control the start and stop of each air injection hole 51a, that is, the start and stop of each air injection hole 51a is controlled by a solenoid valve 52. The air inlet end of the solenoid valve 52 is connected to an external air source or an internal air source (for example, the ore sorting equipment also includes an air pump), and the air outlet end is connected to the air injection hole 51a, wherein the air source can be a component of the ore sorting equipment or an external device. When the ore from the detection mechanism 4 passes through the outside of the valve block 51, the jet hole 51a at the corresponding position can selectively spray the ore under the control of the solenoid valve 52. For example, when bulk materials containing iron ore and copper ore need to be sorted, the jet hole 51a can only spray the iron ore without blowing the copper ore under the control of the solenoid valve 52, thereby ensuring that the iron ore and copper ore can start to produce different movement trajectories here, so that the receiving mechanism 6 can receive the iron ore and copper ore separately and release or store the two separately.

[0045] In this embodiment, the centerline of the outer peripheral surface of the valve block 51 coincides with the reference line L. This ensures that the distances between each ore and the sorting mechanism 5 are approximately equal when passing through the sorting mechanism 5. The new remote motion trajectories of ores of the same type or variety, after being ejected through different air jet holes 51a, are approximately within the same curved surface. This ensures that the receiving mechanism 6 can accurately receive ores of the same type or variety through corresponding channels, and helps maintain or improve the sorting accuracy of the ore sorting equipment.

[0046] In this embodiment, the ore sorting equipment also includes a control module electrically connected to the transmitter 41, the receiver 42 and the solenoid valve 52. The control module can coordinately control the transmitter 41, the receiver 42 and the solenoid valve 52 to ensure that the detection mechanism 4 and the sorting mechanism 5 can complete their respective tasks. The control module generally includes a processor (such as a PLC or CPU), a memory and electronic components connected to the processor, etc., which are well known to those skilled in the art and will not be described in detail here. It is worth noting that there are two ways to implement the control module: one is that it can be integrated into the detection mechanism 4 or the sorting mechanism 5 as their component; the other is that it can be constructed as an independent mechanism, parallel to the detection mechanism 4 and the sorting mechanism 5. Those skilled in the art can choose the implementation method of the control module according to specific actual needs.

[0047] The receiving mechanism 6 mentioned above can be selected as a separate storage mechanism or a separate conveying mechanism, etc. The specific selection needs to be determined according to actual needs. The separate storage structure mainly includes at least two chambers, and the at least two chambers are used to receive different types or qualities of ores from the sorting mechanism 5. Figure 1 and 12 As shown in the figure, the separate conveying mechanism includes a first channel 61 and a second channel 62 separated by a barrier 63. The first channel 61 is used to receive and release the ore that has been blown or struck, such as Figure 1 The second channel 62 is used to receive and release the ore that has not been blown or struck, such as Figure 1 The diamond-shaped ore shown. It should be noted that the terms "circular" and "diamond-shaped" here simply represent different types or qualities of ore and do not limit the specific shape of the ore. The baffle 63 is a curved baffle, the centerline of the outer circumference of which coincides with the reference line L. This ensures that the receiving mechanism 6 can more accurately receive ore of the same type or variety through the corresponding channel, further improving the sorting accuracy of the ore sorting equipment.

[0048] like Figure 2 and Figure 13 As shown, the ore sorting equipment also includes a second frame 2 that is detachably connected to the first frame 1, and the detection mechanism 4, the sorting mechanism 5 and the receiving mechanism 6 are all fixedly arranged in the second frame 2. Preferably, the detachable connection includes a bolt and nut assembly for connecting the first frame 1 and the second frame 2 and an elastic member arranged between the first frame 1 and the second frame 2, and the elastic member can be optionally a compression spring or a rubber gasket. Among them, the first frame 1 and the second frame 2 are only connected during transportation, which is convenient for transportation. During operation, the bolt and nut assembly and the elastic member between the two frames are removed, so that the first frame 1 and the second frame 2 become relatively independent parts, and even a certain gap (such as 1-5 cm) can be left between the two to prevent the vibration of the first frame 1 from being transmitted to the second frame 2 and affecting the working stability of the detection mechanism 4 and the sorting mechanism 5.

[0049] To effectively implement the specific structure of the receiving mechanism 6, the second frame 2 includes a base frame 21. The receiving mechanism 6 also includes an arcuate baffle (i.e., a baffle 63) provided on the base frame 21, and a first channel 61 and a second channel 62 formed within the base frame 21 and separated by the arcuate baffle. It should be noted that the first channel 61 and the second channel 62 are primarily divided based on their functions, and there is no limitation on providing one or more beams within each channel to enhance the overall strength of the second frame 2 or for mounting other items.

[0050] In this embodiment, the transmitter 41 includes a transmitter housing (not shown), which includes a housing for assembling the emission source 411, and an air inlet and an exhaust port spaced apart from each other and connected to the housing. The ore sorting equipment also includes a vortex tube having a gas inlet, a high-temperature gas outlet, and a low-temperature gas outlet, wherein the high-temperature gas outlet or the low-temperature gas outlet of the vortex tube is connected to the air inlet of the transmitter housing. When high-pressure gas enters the vortex tube through the gas inlet, the high-pressure gas is forced to separate into two air flows of different temperatures within the vortex tube. The high-temperature air flow is composed of flowing high-temperature gas, which flows out through the high-temperature gas outlet, while the low-temperature gas is composed of flowing low-temperature gas, which flows out through the low-temperature gas outlet. In hot weather, the low-temperature gas outlet of the vortex tube can be connected to the air inlet of the emitter housing, allowing the low-temperature gas to flow through the emitter 41 and cool the emission source 411 therein, thereby ensuring stable operation of the emission source 411. In cold weather, the high-temperature gas inlet of the vortex tube can be connected to the air inlet of the emitter housing, allowing the high-temperature gas to flow through the emitter 41 and heat the emission source 411 therein, thereby ensuring stable operation of the emission source 411. The high-pressure gas entering the vortex tube can come from the gas source mentioned above.

[0051] In this embodiment, the ore sorting equipment further includes a flap 10 rotatably mounted on the top of the first frame 1, and a heat exchange mechanism mounted on the flap 10 for heating or cooling the emitter 41, see Figure 13 As an example, the heat exchange mechanism mainly includes a driving pump that is connected to the emission source 411 and can drive the heat exchange medium (such as air) to continuously enter and exit the emission source 411, and a heater provided between the driving pump and the emission source 411. The heat exchange mechanism provides hot air or cold air to the emission source 411 by switching the heater on or off to increase or decrease the temperature of the emission source 411, so as to ensure that the emission source 411 can continue to work efficiently. As another example, the heat exchange mechanism is an outdoor air conditioner, and the ore sorting equipment also includes an indoor air conditioner connected to the outdoor air conditioner and located near the emission source 411. With the assistance of the outdoor air conditioner, the indoor air conditioner can cool down or increase the temperature of the emission source 411 according to actual needs, so as to ensure that the emission source 411 can continue to work efficiently in cold weather and hot weather. It is worth noting that the heat exchange mechanism and the vortex tube can exist at the same time and cool down or increase the temperature of the emission source 411 together, or they can exist separately and cool down or increase the temperature of the emission source 411. If necessary, the heat exchange mechanism and / or vortex tube can also be used to cool down or heat up the control module or others.

[0052] In this embodiment, the flap 10 is configured to rotate from a preset closed position and remain in a predetermined open position, forcing the heat exchange mechanism 9 to rotate and stop with the flap 10 from a position within the first frame 1 to a position outside the first frame 1. In this way, when the ore sorting equipment needs to be transported, the flap 10 is in the closed position, forcing the heat exchange mechanism 9 to remain within the first frame 1, thereby facilitating transportation of the ore sorting equipment; and when the ore sorting equipment needs to be used, the flap 10 is in the open position, forcing the heat exchange mechanism 9 to remain outside the first frame 1, thereby ensuring that the heat exchange mechanism 9 has higher heating or cooling efficiency.

[0053] Preferably, the ore sorting equipment may further include a first locking mechanism and a second locking mechanism, wherein the first locking mechanism is provided on the first frame 1 and is used to temporarily lock the flap 10 in a closed position, and the second locking mechanism is provided on the first frame 1 and is used to temporarily lock the flap 10 in an open position. Both the first locking mechanism and the second locking mechanism may preferably be a cost-effective latch and socket structure.

[0054] Preferably, in order to facilitate opening and closing of the flap 10 , the ore sorting equipment may further include a hydraulic damper or a pneumatic damper having one end connected to the flap 10 and the other end connected to the first frame 1 .
