[0002] Magnesite is a core raw material for the development of industries such as refractories and magnesia-based building materials, playing an irreplaceable role in metallurgy and the chemical industry. In recent years, with the continued development of high-grade magnesite resources, mining has gradually expanded to deeper areas and more complex geological regions. This shift in the mining environment has led to changes in the morphology and structure of the ore produced, with the proportion of conical magnesite ore now rising to over 35% of the total mined volume.

[0003] Due to the unique geometric shape and irregular center of gravity distribution of this type of special-shaped ore, the ore frequently rolls and slides on the conveyor belt in the existing conveying system, causing the ore to deviate from the work station, resulting in production interruptions and safety risks. The rolling and collision of the ore also aggravates the spread of dust. In addition, the traditional limiting device cannot adapt to the shape of the conical ore, and the mechanical fixed pressure plate is prone to crushing the ore. Therefore, there is an urgent need for a conveying device for conical ore. Summary of the Invention

DETAILED DESCRIPTION

[0017] The following is a combination of specific implementation cases and attached Figure 1-5 The present invention is further described below, but the present invention is not limited to these embodiments.

[0018] A conical magnesite ore conveying device, such as Figure 1-5 As shown, it includes: a transmission mechanism 10, a water collection bin 11, a circulating spray mechanism, a dust suppression cover 12, a hydraulic cylinder 13, a limiting mechanism and a monitoring system; the transmission mechanism 10 is provided with a conveyor belt 14 and a baffle 15, the conveyor belt 14 is provided with a partition 16 and a water filter hole 17, the baffle 15 is arranged on both sides of the conveyor belt 14, and the baffle 15 is provided with a drainage channel 18; the transmission mechanism 10 is arranged in the water collection bin 11, and the water collection bin 11 is provided with a filter plate 19 for filtering dust and impurities on the surface of the magnesite ore; the circulating spray mechanism is arranged above the conveyor belt 14, and the circulating spray mechanism is connected to the water collection bin 11; the dust suppression cover 12 is arranged on the conveyor belt 1 4, and the hydraulic cylinder 13 is fixed on the dust suppression cover 12; the limiting mechanism includes a connecting seat 20, a connecting frame 21 and a pressure roller 22, the connecting seat 20 is connected to the telescopic end of the hydraulic cylinder 13, the connecting frame 21 is hinged to the connecting seat 20, and the pressure roller 22 is rotatably connected to the connecting frame 21; the monitoring system includes a water level monitoring sensor 23, a position sensor 24 and an industrial camera 25, the industrial camera 25 is installed in the dust suppression cover 12, and is used to monitor the position of the partition 16 and the dolomite ore, the position sensor 24 is set on the connecting frame 21, and monitors the position of the pressure roller 22 in real time, and the water level monitoring sensor 23 monitors the water level in the water collection bin 11.

[0019] With the above structure, the ore is transported in sections via the partitions 16 on the conveyor belt 14. The hydraulic cylinder 13 drives the limiting mechanism up and down, dynamically adjusting the pressure of the pressure roller 22 according to the geometric shape of the conical ore. This prevents the ore from rolling, shifting, or sliding during transportation, and avoids the ore crushing problem caused by the rigid contact of traditional mechanical fixed pressure plates. The baffle 15 and the partitions 16 on the conveyor belt 14 work together to prevent the ore from sliding due to surface moisture adhesion, thereby improving transportation stability. The hinged design of the connecting frame 21 and the connecting seat 20 allows the angle of the pressure roller 22 to be adjusted. When the center of gravity of the conical ore is offset or the surface is irregular, the pressure roller 22 is subjected to the reaction force of the ore, causing the connecting frame 21 to swing slightly about the hinge point, achieving automatic adjustment of the inclination angle of the pressure roller 22, ensuring that the roller surface always fits the conical surface of the ore, and avoiding the risk of crushing due to local stress concentration.

[0020] During the transmission process, water mist is sprayed on the dolomite ore through a circulating spraying mechanism, and combined with the semi-enclosed structure of the dust suppression hood 12, the dust generated by the friction and collision of the dolomite ore is effectively suppressed, thereby reducing air pollution; and the sewage after spraying flows into the water collection bin 11 through the water filter holes 17 on the conveyor belt 14 and the drainage channel 18 on the baffle 15, and the large particles of dust and impurities in the water are filtered through the filter plate 19, and the filtered water is extracted and recycled by the water pump 29, realizing the closed-loop recycling of water resources, reducing the consumption of water resources and the problem of sewage discharge, and achieving the purpose of environmental protection.

[0021] The industrial camera 25 captures the image of the conveyor belt 14 in real time, making it easy to identify the moving position of the partition 16 and the distribution and accumulation of the ore, and the position sensor 24 provides real-time feedback on the current height of the pressure roller 22, thereby accurately identifying the position of the partition 16 and controlling the pressure roller 22 to lift in advance, ensuring that the pressure roller 22 does not interfere with the partition 16, thereby extending the service life of the components.

[0022] Specifically, when the industrial camera 25 detects that the partition 16 is approaching the position of the pressure roller 22, the controller sends a lifting command to the hydraulic system based on the data from the camera and the position sensor 24, so that the hydraulic cylinder 13 drives the pressure roller 22 to lift upward to ensure that the partition 16 can pass through unimpeded. When the industrial camera 25 confirms that the partition 16 has crossed the projection area of ​​the pressure roller 22, it controls the pressure roller 22 to move downward.

[0023] Specifically, the transmission mechanism 10 includes a base, a driving roller, a driven roller, a conveyor belt 14 and a driving motor.

[0024] Specifically, the position sensor 24 adopts the UC500-18GS-IUEP-IO-V15 ultrasonic sensor produced by Pepperl+Fuchs; the water level monitoring sensor 23 adopts the DYP-A17 ultrasonic sensor produced by DYP.

[0025] In an embodiment of the present invention, Figure 1-5 As shown, the circulating spraying mechanism includes a support frame 26, a connecting pipe 27, a nozzle 28 and a water pump 29. The support frame 26 is arranged on the baffle 15, and the water pump 29 is fixed on one side of the water collecting bin 11. The input end of the water pump 29 is connected to the water collecting bin 11, and the output end of the water pump 29 is connected to the connecting pipe 27, the connecting pipe 27 is connected to the nozzle 28, and the nozzle 28 is arranged on the support frame 26.

[0026] The position of the nozzle 28 is fixed by the support frame 26, and the water pump 29 is operated to pump out the water in the water collection bin 11 and send it to the nozzle 28 through the connecting pipe 27. Water mist is then sprayed out through the nozzle 28, thereby reducing the dust generated by the friction and collision of the ore during the transmission process. The sprayed water flows through the drainage channel 18 and the water filter hole 17 to the filter plate 19, and the sewage is filtered by the filter plate 19. The filtered water flows into the water collection bin 11 for recycling.

[0027] Specifically, at least four groups of nozzles 28 are provided on the top of the conveyor belt 14, so as to achieve the purpose of reducing dust at multiple positions during the transmission process of the conveyor belt 14; a dust cover is provided between two adjacent support frames 26, and a limiting mechanism, a hydraulic cylinder 13, a position sensor 24 and an industrial camera 25 are provided in the dust cover, so as to achieve the purpose of monitoring multiple positions of the conveyor belt 14.

[0028] In an embodiment of the present invention, a through groove is provided on the side wall of the water collecting bin 11, one end of the filter plate 19 is connected to the mounting portion 30, the filter plate 19 is installed in the water collecting bin 11 through the through groove, and part of the mounting portion 30 is embedded in the through groove; a sealing strip is provided on the inner wall of the through groove.

[0029] By providing a through groove on the side wall of the water collecting bin 11, the filter plate 19 is inserted into the water collecting bin 11 through the through groove, and the mounting portion 30 is embedded in the through groove and tightly cooperates with the sealing strip, thereby facilitating the disassembly and cleaning of the filter plate 19 while also preventing the water in the water collecting bin 11 from being discharged from the gap between the through groove and the mounting portion 30.

[0030] In an embodiment of the present invention, Figure 1-3 As shown, it also includes: a collection bin 31, a filter box 32, a support plate 33 and a water filter plate 34; the filter box 32 is arranged on one side of the transmission mechanism 10; the support plate 33 and the water filter plate 34 are provided in the filter box 32, and the support plate 33 is provided with a through hole; the collection bin 31 is provided on the support plate 33, and drainage outlets are provided on both sides and the bottom of the collection bin 31.

[0031] After being transported by the conveyor belt 14, the magnesite ore falls into the aggregate bin 31. The moisture and impurities remaining on the surface of the magnesite ore are discharged through the drain port of the aggregate bin 31. The impurities in the water are filtered again by the water filter plate 34 and then fall into the filter box 32, so that the filtered water can be reused. By draining the moisture on the surface of the magnesite ore, it is convenient to carry out the next process operation on the magnesite ore.

[0032] In the embodiment of the present invention, the water filter plate 34 is a detachable structure.

[0033] By setting the water filter plate 34 as a detachable structure, the water filter plate 34 can be disassembled for cleaning, thereby preventing impurities from clogging the water filter holes 17 of the water filter plate 34 and affecting the water filtering effect.

[0035] In an embodiment of the present invention, Figure 1-3 As shown, it also includes: adjustable pillars 36 and protective plates 37. The adjustable pillars 36 are arranged on both sides of the top of the filter box 32. The protective plates 37 are hinged to the telescopic ends of the adjustable pillars 36, and the protective plates 37 are opposite to the guide plates 35.

[0036] By providing adjustable pillars 36 and protective plates 37, the height and tilt angle of the protective plates 37 can be adjusted according to actual use requirements, thereby preventing magnesite ore from flying out of the area of ​​the guide plate 35 and the collection bin 31, thereby improving the adaptability of the equipment.

[0038] In the embodiment of the present invention, a buffer pad is provided on the surface of the conveyor belt 14 , and a rubber sleeve is provided on the outer side of the pressure roller 22 .

[0039] By providing a buffer pad on the surface of the conveyor belt 14 and a rubber sleeve on the outside of the pressure roller 22, a buffering effect is achieved when the dolomite ore falls on the conveyor belt 14, and the pressure roller 22 provided with the rubber sleeve also plays a buffering role when it comes into contact with the dolomite ore, avoiding rigid contact and crushing the dolomite ore.
