[0002] The quartz sand magnetic separation device for iron removal is used to magnetically separate the iron filings and iron slag contained in the quartz sand by means of magnetic block adsorption. During the magnetic separation and iron removal process, the iron filings and iron slag in the quartz sand are adsorbed by the magnetic force of the magnetic block onto the conveyor belt of the auxiliary conveyor. The main conveyor belt of the main conveyor and the auxiliary conveyor belt of the auxiliary conveyor are in operation. The main conveyor belt transports the magnetically separated quartz sand into a container for quartz sand, and the auxiliary conveyor belt transports the iron filings and iron slag into a container for iron filings and iron slag. When the current quartz sand magnetic separation and iron removal equipment is in use, due to the small volume of quartz sand, it will stick to the conveyor belt due to the rubber material problem of the conveyor belt during iron removal, resulting in the need for manual cleaning of the conveyor belt, which not only increases the workload, but also increases the waste rate of quartz sand, while causing serious wear of the conveyor belt and increasing the cost of use.

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0022] Example 1

[0023] Reference Figure 1 , which is the first embodiment of the utility model, provides a quartz sand magnetic separation and iron removal equipment, which includes a magnetic separation unit 100, a transmission unit 200, a transport unit 300 and a fixing unit 400. Through the mutual cooperation of the magnetic separation unit 100 and the transmission unit 200, the quartz sand can be removed from the conveyor belt 304, so that the staff can clean the conveyor belt 304, and at the same time, the waste rate of quartz sand can be reduced.

[0024] Specifically, the magnetic separation unit 100 includes an auxiliary component 101 and a cleaning component 102 connected to one end of the auxiliary component 101; the transmission unit 200 includes a first fixed frame 201 and a transmission component 202 connected to the top of the fixed frame 201; the first fixed frame 201 is provided with a discharge outlet 201a; the transport unit 300 includes a second fixed frame 301, two groups of rotating shafts 302 connected to both sides of the inner wall of the second fixed frame 301, a driving motor 303 connected to one group of the rotating shafts 302, and a transmission belt 304 arranged outside the two groups of rotating shafts 302; the fixing unit 400 includes a fixing plate 401 and a fixing block 402 fixedly connected to both sides of the fixing plate 401.

[0025] During use, the cleaning component 102 is respectively installed on the auxiliary component 101 and a section of the second fixed frame 301. The quartz sand is located on the top of the transmission component 202 through transportation. Then the transmission component 202 is started, and the quartz sand falls on the top of the transmission component 202. While the quartz sand falls, the magnetic quartz sand is adsorbed by the auxiliary component 101, and then the cleaning component 102 removes the quartz sand adsorbed on the outer surface of the auxiliary component 101. At the same time, the magnetic quartz sand is driven to roll by the auxiliary component 101. When the magnetic quartz sand moves to the point where there is no magnetic adsorption, the tilt of the fixed plate 401 assists the quartz sand to fall onto the conveyor belt 304 for easy collection. The cleaning component 102 clears the quartz sand on the conveyor belt 304, and the non-magnetic quartz sand is assisted by the rotation of the transmission component 202 to fall, thereby achieving classification.

[0026] In summary, the cleaning component 102 provided in the present invention can remove the quartz sand adhered to the auxiliary component 101 and the conveyor belt 304, thereby reducing the workload and lowering the waste rate of the quartz sand.

[0027] Example 2

[0028] Reference Figure 2 , which is the second embodiment of the present utility model, provides a quartz sand magnetic separation and iron removal device, wherein the setting of the cleaning component 102 can remove the magnetic quartz sand on the rolling belt 101d.

[0029] Specifically, the cleaning assembly 102 includes a fixing bar 102a bolted to both sides of the auxiliary assembly 101, a groove 102b disposed within the fixing bar 102a, five sets of springs 102c connected to the inner wall of the groove 102b, and a cleaning bar 102d fixedly connected to one side of the five sets of springs 102c. The cleaning bar 102d includes a mounting bar 102d-1 fixedly connected to one side of the springs 102c, and a cleaning bar 102d-2 bolted to one side of the mounting bar 102d-1. One side of the cleaning bar 102d-2 is U-shaped and engages with one side of the mounting bar 102d-1. The length of the spring 102c is less than the depth of the groove 102b, so that one side of the mounting bar 102d-1 is embedded in the groove 102b, and the cleaning bar 102d-2 contacts the auxiliary assembly 101. The fixing bar 102a is tilted 30° toward the auxiliary assembly 101.

[0030] Furthermore, the auxiliary assembly 101 includes a connecting frame 101a, two sets of rolling shafts 101b connected to the inner wall of the connecting frame 101a, a first power motor 101c connected to one side of the rolling shafts 101b, a rolling belt 101d disposed on the outer surface of the two sets of rolling shafts 101b, and a magnetic block 101e disposed in the middle of the two sets of rolling shafts 101b. A motor shaft is disposed in the middle of the rolling shafts 101b and is fixedly connected to the first power motor 101c. The rolling belt 101d is made of rubber.

[0031] Furthermore, a magnetic shielding plate is provided on the top of the magnetic block 101e, and connecting blocks are installed on both sides of the magnetic block 101e, and one side of the connecting block is bolted to the inner wall of the connecting frame 101a.

[0032] When in use, start the first power motor 101c, and the first power motor 101 drives the rolling shaft 101b to rotate through the motor shaft. The rotation of the rolling shaft 101b can drive the rolling belt 101d to rotate. When the quartz sand is at the bottom of the magnetic block 101e, the magnetic block 101e can absorb the magnetic quartz sand, and then the quartz sand is rolled at the same time through the rotation of the rolling belt 101d. When the magnetic quartz sand moves to the edge of the magnetic block 101e, the magnetism disappears, so that the quartz sand can fall due to gravity. At the same time, due to the small volume of the quartz sand, Because the rolling belt 101d is made of rubber and has slight adhesion, the quartz sand will adhere to the outer surface of the rolling belt 101d. When the quartz sand adhered to the outer surface of the rolling belt 101d moves to the cleaning bar 102d-2, the cleaning bar 102d-2 can clean the quartz sand on the outer surface of the rolling belt 101d. For quartz sand with a larger volume, the cleaning bar 102d-2 drives the spring 102c to expand and contract in the groove 102b due to the setting of the mounting bar 102d-1, so that the cleaning component 102 can adapt to quartz sand of different volumes.

[0033] In summary, the present invention can remove quartz sand adhering to the outer surface of the rolling belt 101d through the setting of the cleaning strip 102d-2. At the same time, the setting of the spring 102c can enable the cleaning component 102 to adapt to quartz sand of various volumes, reduce the damage of quartz sand to the outer surface of the rolling belt 101d, and reduce the replacement frequency of the rolling belt 101d, thereby reducing costs. In addition, the cleaning strip 102d-2 is installed on the outer surface of the mounting strip 102d-1 by bolts. When the cleaning strip 102d-2 is damaged, the cleaning strip 102d-2 can be directly replaced, further reducing costs.

[0034] Example 3

[0035] Reference Figure 3 , which is the third embodiment of the present utility model, provides a quartz sand magnetic separation and iron removal device, in which the horizontal grooves on the outer surface of the connecting roller 202b can drive the quartz sand to rotate and increase the residence time of the quartz sand, so that the magnetic quartz sand can be fully screened and the efficiency of magnetic separation can be improved.

[0036] Furthermore, the transmission assembly 202 includes two groups of vertical plates 202a fixedly connected to the top of the first fixed frame 201, connecting rollers 202b connected to the inner walls of the vertical plates 202a, and a second power motor 202c installed on the outside of the vertical plates 202a.

[0037] Furthermore, the inner diameter of the connecting roller 202b is smaller than that of the two ends, and an intermediate shaft is fixedly connected to the connecting roller 202b, a section of which passes through the vertical plate 202a and is connected to the second power motor 202c. The outer surface of the connecting roller 202b is provided with horizontal grooves distributed in an annular manner.

[0038] Furthermore, the fixing plate 401 is inclined at 30 degrees, and the top of the fixing plate 401 is located directly below one side of the magnetic block 101e.

[0039] When in use, start the second power motor 202c, and the second power motor 202c can drive the connecting roller 202b to rotate slowly through the intermediate shaft. When the quartz sand falls above the connecting roller 202b, the horizontal grooves on the outer surface of the connecting roller 202b can drive the quartz sand to rotate, while increasing the residence time of the quartz sand, so that the magnetic quartz sand can be fully screened, thereby improving the efficiency of magnetic separation.
