Description

Technical Field

[0001] This solution belongs to the field of sorting devices, specifically involving an ore waste sorting device that combines photoelectric recognition and magnetic separation. Background Technology

[0002] With the gradual maturation of domestic raw ore pre-disposal technology, preliminary pre-selection of ore can achieve the purpose of pre-enrichment, which can significantly reduce mineral processing costs, thereby improving the efficiency of mineral resource development and utilization, and has obvious economic benefits.

[0003] A search revealed that the invention patent application with publication number CN110773316A discloses a combined pre-selection and waste disposal process for weakly magnetic and difficult-to-process iron ore. This process classifies weakly magnetic and difficult-to-process iron ore of 0-100mm particle size into four sizes: 0-5mm, 5-15mm, 15-50mm, and 50-100mm. For the 0-5mm size, a fully sealed spiral dry magnetic separator is used for three-stage pre-selection and waste disposal. For the 5-15mm size, a strong magnetic induction roller is used for two-stage pre-selection and waste disposal. For the 15-50mm and 50-100mm size sizes, X-ray transmission intelligent separation is used for one-stage pre-selection and waste disposal.

[0004] In existing technologies, the presence of contaminants on the surface of the ore can affect subsequent photoelectric recognition, leading to inaccurate identification. Additionally, some ore may be mixed into the waste material, resulting in waste. Utility Model Content

[0005] The purpose of this solution is to provide an ore waste sorting device that combines photoelectric recognition and magnetic separation. This solves the problem in existing technologies where dirt on the ore surface can affect subsequent photoelectric recognition, leading to inaccurate identification. It also addresses the issue of some ore being mixed into the waste material, causing waste.

[0006] To achieve the above objectives, this solution provides an ore waste sorting device that combines photoelectric recognition and magnetic separation, including a diversion box. An identification channel is fixedly connected to the left side of the diversion box. An inlet is connected to the upper left side of the identification channel. A cleaning mechanism is installed inside the inlet. A conveyor belt is installed at the bottom inner side of the identification channel. A magnetic separation component is installed at the top inner side of the identification channel. A radiation source is installed at the top inner side of the identification channel. A support plate is fixedly connected to the inner wall of the identification channel. A detector is installed at the upper end of the support plate, and the detector corresponds to the position of the radiation source. An air pipe is fixedly connected to the side wall of the diversion box, and the air pipe penetrates the diversion box. An air gun array is connected to the end of the air pipe located inside the diversion box, and the position of the air gun array corresponds to the end of the conveyor belt.

[0007] The principle of this solution is as follows: When the material enters the inlet, it can be guided by the guide hood and pass smoothly through the inner ring of the ring pipe. Then, it can be cleaned by the high-pressure nozzles on the ring pipe to prevent dirt on the material from blocking photoelectric recognition. After solid-liquid separation by the guide plate, the material falls onto the conveyor belt. After photoelectric recognition by the X-ray source and detector, it is then removed by the air gun. In this way, waste and ore can be discharged after being separated by the diverter. In addition, a portion of the ore on the conveyor belt is sucked up by the magnetic separator and collected into the collection bin by the scraper for unified discharge later. This reduces the waste grade when discarding ore and avoids excessive accumulation of ore due to inaccurate recognition.

[0008] The technical advantage of this solution is that by installing a magnetic separation component on the inner top of the device, a portion of the ore is drawn in by the magnetic separator and collected into the collection bin by a scraper, and then discharged uniformly in the later stage. This reduces the grade of waste ore and avoids excessive accumulation of ore due to inaccurate identification.

[0009] By setting a cleaning mechanism inside the inlet of the device, when the material enters the inlet, it can be guided by the guide shroud and pass smoothly through the inner ring of the ring pipe. Then it can be cleaned by the nozzle on the ring pipe under high pressure, avoiding the obstruction of photoelectric recognition by dirt on the material.

[0010] Furthermore, a diversion seat is fixedly connected to the inner wall of the diversion box, and support legs are welded to both the diversion box and the identification channel. A drain pipe is connected to the bottom of the identification channel. The diversion seat helps to separate and discharge waste and ore.

[0011] Furthermore, the cleaning mechanism includes two fixed brackets fixedly connected to the inner wall of the feed inlet. A ring pipe is fixedly connected to the ends of both brackets. A nozzle is installed on the inner wall of the ring pipe, and an air inlet is connected to the outer wall of the ring pipe. The air inlet penetrates the feed inlet and extends to the outside of the feed inlet. This cleaning mechanism effectively cleans the ore entering the feed inlet, preventing contaminants on the material from obstructing photoelectric recognition.

[0012] Furthermore, a flow guide shroud, which is funnel-shaped, is fixedly connected to the inner side of the feed inlet and above the annular pipe. The flow guide shroud guides the ore entering the feed inlet, allowing it to pass smoothly through the inner ring of the annular pipe and be cleaned.

[0013] Furthermore, a guide plate is fixedly connected to the inner wall of the identification channel. The guide plate is located below the feed inlet and is inclined. The guide plate guides the ore entering through the feed inlet onto the conveyor belt.

[0014] Furthermore, the magnetic separation assembly includes a magnetic separator fixedly installed at the top inner side of the identification channel, located above the conveyor belt. A fixed rod is fixedly connected to the top inner side of the identification channel and to the right of the magnetic separator. A scraper is fixedly connected to the end of the fixed rod, and the scraper abuts against the magnetic separator. A fixed shaft is fixedly connected to the inner wall of the identification channel, and a collection bin is rotatably connected to the shaft. The magnetic separation assembly aims to reduce the grade of waste ore during disposal.

[0015] Furthermore, a connecting frame is fixedly connected to the upper end of the collection bin, and a connecting seat is fixedly connected to the upper end of the connecting frame. A hydraulic cylinder is hinged to the top inner side of the diversion box, and a ball head is fixedly connected to the end of the telescopic shaft of the hydraulic cylinder. The ball head is movably connected to the connecting seat. Through the cooperation of the hydraulic cylinder, the ball head, and the connecting seat, the collection bin can be deflected around the fixed shaft as the axis. Attached Figure Description

A diversion seat 12 is fixedly connected to the inner wall of the diversion box 1. Support legs 14 are welded to both the diversion box 1 and the recognition channel 2. A drain pipe 13 is connected to the bottom of the recognition channel 2. The diversion seat 12 helps to separate and discharge waste and ore.

[0023] like Figure 2 As shown, a cleaning mechanism 4 is provided inside the feed inlet 3. This cleaning mechanism 4 cleans the ore entering the feed inlet 3, preventing contaminants from obstructing photoelectric recognition. The cleaning mechanism 4 includes two fixed brackets 41 fixedly connected to the inner wall of the feed inlet 3. A ring pipe 42 is fixedly connected to the ends of the two brackets 41. A nozzle 43 is provided on the inner wall of the ring pipe 42, and an air inlet 44 is connected to the outer wall of the ring pipe 42. The air inlet 44 penetrates the feed inlet 3 and extends to the outside of the feed inlet 3. A funnel-shaped guide hood 45 is fixedly connected inside the feed inlet 3 and above the ring pipe 42. The guide hood 45 guides the ore entering the feed inlet 3, allowing it to pass smoothly through the inner ring of the ring pipe 42 and be cleaned. A guide plate 46 is fixedly connected to the inner wall of the recognition channel 2, located below the feed inlet 3, and is inclined. The guide plate 46 is designed to guide the ore entering through the feed inlet 3 onto the conveyor belt 5.

[0024] like Figure 2 , Figure 3 , Figure 4As shown, a magnetic separation assembly 6 is installed on the top inner side of the identification channel 2. The magnetic separation assembly 6 aims to reduce the grade of waste ore during disposal. The magnetic separation assembly 6 includes a magnetic separator 61 fixedly installed on the top inner side of the identification channel 2, located above the conveyor belt 5. A fixed rod 62 is fixedly connected to the top inner side of the identification channel 2 and to the right of the magnetic separator 61. A scraper 63 is fixedly connected to the end of the fixed rod 62, and the scraper 63 abuts against the magnetic separator 61. A fixed shaft 64 is fixedly connected to the inner wall of the identification channel 2, and a collection bin 65 is rotatably connected to the shaft of the fixed shaft 64. A connecting frame 67 is fixedly connected to the upper end of the collection bin 65, and a connecting seat 68 is fixedly connected to the upper end of the connecting frame 67.

Through the cooperation of hydraulic cylinder 66, ball head 69 and connecting seat 68, the collection bin 65 can be deflected around fixed shaft 64.

[0025] The specific implementation process of this utility model is as follows: When the material enters the inlet 3, it can be guided by the guide hood 45 and pass smoothly through the inner ring of the ring pipe 42. Then it can be cleaned by the nozzle 43 on the ring pipe 42 under high pressure to prevent dirt on the material from blocking photoelectric recognition. After the material passes through the solid-liquid separation of the guide plate 46, it falls onto the conveyor belt 5. After photoelectric recognition by the X-ray source 7 and the detector 9, it is started by the air gun 11 to remove it. In this way, waste and ore can be separated by the diverter 12 and discharged. In addition, the magnetic separator 61 sucks up a part of the ore on the conveyor belt 5 and collects it into the collection bin 65 by the scraper 63 for unified discharge later. This has the purpose of reducing the waste grade when discarding ore and avoiding excessive ore accumulation due to inaccurate recognition.

[0026] This solution involves installing a magnetic separation component 6 on the inner top of the device. A portion of the ore is drawn up by the magnetic separator 61 and collected into the collection bin 65 by the scraper 63, and then discharged uniformly. This reduces the grade of waste ore and avoids excessive accumulation of ore due to inaccurate identification.

[0027] By setting a cleaning mechanism 4 inside the feed inlet 3 of the device, when the material enters the feed inlet 3, it can be guided by the guide shroud 45 and pass smoothly through the inner ring of the ring pipe 42. Then it can be cleaned by the nozzle 43 on the ring pipe 42 under high pressure, so as to avoid the dirt on the material from blocking the photoelectric recognition.
