Description

Technical Field

[0001] The utility model relates to the field of magnetic separators, in particular to a magnetic separation mechanism of a magnetic separator. Background Art

[0002] Magnetic separators are generally used for fluid iron removal in order to remove iron-containing substances from powders or liquids, thus facilitating the recycling of powders or liquids.

[0003] At present, there are many types of magnetic separators used for removing iron from liquids. For example, a Chinese patent with patent publication number CN108246498B discloses a magnetic separator, which includes a main drum capable of discharging magnetic sludge to the outside of the treated liquid and a sub-drum arranged on the upstream side of the main drum and magnetizing the magnetic sludge in the treated liquid. The sub-drum is arranged in a state of being immersed in the treated liquid, and an upper flow path for the treated liquid to flow is formed on the upper part of the sub-drum, and a lower flow path for the treated liquid to flow is formed on the lower part of the sub-drum.

[0004] The magnetic separator provided by the above patent has a main drum and a secondary drum located above the same plane. Therefore, it can only remove iron from liquids because the liquid has strong fluidity. When the liquid level of the liquid storage part is higher than the opening, the liquid will flow around the main drum, and the iron-containing substances will adhere to the main drum under the action of magnetic force. However, for powder materials, this structure of the magnetic separator is not conducive to removing iron from them because the flow is poor and it is inconvenient to continuously output the liquid storage part, that is, the practicality of the magnetic separator is low.

[0024] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0026] Example 1

[0027] like Figure 1 , Figure 4 , Figure 5As shown, a magnetic separation mechanism of a magnetic separator includes a shell 1 and a magnetic separation assembly 2. The shell 1 is configured to have three spaces, upper, middle and lower, and the junction of two adjacent spaces is narrow. At the same time, the bottom of the upper space is configured to be a frustum structure. The magnetic separation assembly 2 includes two rollers 21 distributed up and down, and the two rollers 21 are respectively arranged in the middle space and the lower space. The end shafts of the rollers 21 penetrate the side wall of the shell 1, and the end shaft of a certain roller 21 is connected to the output shaft of the motor. At the same time, the end shafts of the two rollers 21 are connected by a transmission belt 22, and a plurality of magnets 24 are evenly distributed on the inner side of the roller 21. When the device is used to remove iron from materials, the materials are put into the upper space of the shell 1, and under the action of gravity, the materials pass through the bottom of the upper space and fall to the middle space. The materials falling in the middle space first fall on the roller 21. Because the roller 21 rotates, the continuously falling materials fall at different positions of the roller 21. Because the magnet 24 is arranged in the drum 21, under the action of the magnetic field, when the material contacts the drum 21, the iron-containing substances in the material will adhere to the side wall of the drum 21, and the materials that are not adhered to the drum 21 will continue to fall after separating from the drum 21 and fall into the lower space. The materials that fall into the lower space also fall on the drum 21 first, and because the magnet 24 is arranged in the drum 21, the iron-containing substances are adhered to the drum 21. Through the cooperation of the upper and lower drums 21, the secondary treatment of the material is realized, and the iron-containing substances in the material are effectively removed. In addition, because the shell 1 and the drum 21 are distributed in the vertical direction, the material can fall under the action of its own gravity, which is suitable for the iron removal of powder and liquid, changing the current situation that the existing magnetic separator can only remove iron from liquid, and improving the practicality of the magnetic separation device.

[0028] like Figure 1 , Figure 2 As shown, in order to limit the falling of materials, a funnel 11 is provided at the junction of two adjacent spaces. The funnel 11 is arranged in a conical structure. The length of the funnel 11 is equal to the length of the shell 1, and the upper end is in smooth contact with the bottom of the upper space. The structural characteristics of the funnel 11 are utilized to reduce the passage through which the materials pass, limit the falling of the materials, and thereby avoid a large amount of materials falling at one time to affect the iron removal treatment of the materials by the drum 21.

[0029] like Figure 4 , Figure 6As shown, in order to promptly remove the iron-containing materials adhering to the roller 21, a feeding device 3 is provided on the side of each roller 21. The feeding device 3 is tilted and is set as a rectangular tube structure. The upper end of the upper side wall of the feeding device 3 contacts the roller 21, the upper end of the lower side wall is located below the roller 21, the upper end of the lower side wall of the feeding device 3 protrudes from the upper end of the upper side wall, and the upper end of the feeding device 3 is located above the lower end of the roller 21. Since the upper side wall of the feeding device 3 contacts the roller 21, the upper side wall of the feeding device 3 scrapes off the materials adhering to the roller 21 during the rotation of the roller 21. Since the upper end of the lower side wall of the feeding device 3 protrudes from the upper end of the upper side wall, the materials separated from the feeding device 3 fall on the lower side wall of the feeding device 3 and move downward along the tilt direction of the feeding device 3. In addition, the lower end of the feeding device 3 is located outside the housing 1, and the materials can be discharged from the housing 1 along the feeding device 3. Since the material conveying device 3 is arranged above the lower end of the drum 21 , it is avoided that the existence of the material conveying device 3 affects the falling of the materials in the housing 1 .

[0030] Example 2

[0031] like Figure 1 , Figure 4 , Figure 5As shown, a magnetic separation mechanism of a magnetic separator includes a shell 1 and a magnetic separation assembly 2. The shell 1 is configured to have three spaces, upper, middle and lower, and the junction of two adjacent spaces is narrow. At the same time, the bottom of the upper space is configured to be a frustum structure. The magnetic separation assembly 2 includes two rollers 21 distributed up and down, and the two rollers 21 are respectively arranged in the middle space and the lower space. The end shafts of the rollers 21 penetrate the side wall of the shell 1, and the end shaft of a certain roller 21 is connected to the output shaft of the motor. At the same time, the end shafts of the two rollers 21 are connected by a transmission belt 22, and a plurality of magnets 24 are evenly distributed on the inner side of the roller 21. When the device is used to remove iron from materials, the materials are put into the upper space of the shell 1, and under the action of gravity, the materials pass through the bottom of the upper space and fall to the middle space. The materials falling in the middle space first fall on the roller 21. Because the roller 21 rotates, the continuously falling materials fall at different positions of the roller 21. Because the magnet 24 is arranged in the drum 21, under the action of the magnetic field, when the material contacts the drum 21, the iron-containing substances in the material will adhere to the side wall of the drum 21, and the materials that are not adhered to the drum 21 will continue to fall after separating from the drum 21 and fall into the lower space. The materials that fall into the lower space also fall on the drum 21 first, and because the magnet 24 is arranged in the drum 21, the iron-containing substances are adhered to the drum 21. Through the cooperation of the upper and lower drums 21, the secondary treatment of the material is realized, and the iron-containing substances in the material are effectively removed. In addition, because the shell 1 and the drum 21 are distributed in the vertical direction, the material can fall under the action of its own gravity, which is suitable for the iron removal of powder and liquid, changing the current situation that the existing magnetic separator can only remove iron from liquid, and improving the practicality of the magnetic separation device.

[0032] like Figure 1 , Figure 2 As shown, in order to limit the falling of materials, a funnel 11 is provided at the junction of two adjacent spaces. The funnel 11 is arranged in a conical structure. The length of the funnel 11 is equal to the length of the shell 1, and the upper end is in smooth contact with the bottom of the upper space. The structural characteristics of the funnel 11 are utilized to reduce the passage through which the materials pass, limit the falling of the materials, and thereby avoid a large amount of materials falling at one time to affect the iron removal treatment of the materials by the drum 21.

[0033] like Figure 4 , Figure 6As shown, in order to promptly remove the iron-containing materials adhering to the roller 21, a feeding device 3 is provided on the side of each roller 21. The feeding device 3 is tilted and is set as a rectangular tube structure. The upper end of the upper side wall of the feeding device 3 contacts the roller 21, the upper end of the lower side wall is located below the roller 21, the upper end of the lower side wall of the feeding device 3 protrudes from the upper end of the upper side wall, and the upper end of the feeding device 3 is located above the lower end of the roller 21. Since the upper side wall of the feeding device 3 contacts the roller 21, the upper side wall of the feeding device 3 scrapes off the materials adhering to the roller 21 during the rotation of the roller 21. Since the upper end of the lower side wall of the feeding device 3 protrudes from the upper end of the upper side wall, the materials separated from the feeding device 3 fall on the lower side wall of the feeding device 3 and move downward along the tilt direction of the feeding device 3. In addition, the lower end of the feeding device 3 is located outside the housing 1, and the materials can be discharged from the housing 1 along the feeding device 3. Since the material conveying device 3 is arranged above the lower end of the drum 21 , it is avoided that the existence of the material conveying device 3 affects the falling of the materials in the housing 1 .

[0034] like Figure 2 , Figure 3 As shown, in order to facilitate rapid disassembly and maintenance of the device according to needs, through holes 12 are provided on the end walls of the middle space and the lower space of the shell 1, and a blocking plate 15 is detachably provided at the through hole 12 through bolt connection. The diameter of the through hole 12 is larger than the diameter of the roller 21. In addition, through holes 14 are provided on the side walls of the middle space and the lower space of the shell 1, and a card slot 13 is provided on the inner side. The card slot 13 is connected to the through hole 14. The feed device 3 passes through the through hole 14, and the edge extends into the card slot 13. In addition, the clinker device 3 is connected to the shell 1 by bolts. This arrangement can remove the restrictions of the blocking plate 15 and the feed device 3 by removing the bolts, and provide support for the rapid disassembly and assembly of the blocking plate 15 and the feed device 3, and the replacement of the roller 21 and the feed device 3.

[0035] like Figure 5 As shown, in addition, a cavity 23 with an annular structure is provided on the inner side of the drum 21, and a plurality of magnets 24 are evenly distributed on the side wall of the cavity 23, the magnets 24 are bonded to the side wall of the drum 21, and a sealing plate 25 is detachably provided at the end of the cavity 23.
