Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand, in particular to a double magnetic separator. Background Art

[0002] Quartz sand is quartz particles made from quartz stone through crushing, screening and other processes.

[0003] Natural quartz sand generally contains iron impurities. The core value of quartz sand lies in its high-purity silicon dioxide, and iron is an impurity. The presence of iron will reduce the purity of quartz sand. Therefore, quartz sand usually needs to be deironed. The current deironing machines generally remove iron in one go. If multiple deironing operations are required, the staff will need to repeatedly feed the material, which is more cumbersome.

[0004] In addition, in non-contact iron removers, the thickness of the material laid on the conveyor belt will greatly affect the iron removal effect. Currently, there is generally no adjustment mechanism in the iron remover that acts on the material thickness. Improvements are needed to address the above problems. Utility Model Content

[0031] Reference Figure 1-Figure 4According to an embodiment of a double magnetic separator of the present invention, it includes a base 11, in which a No. 1 magnetic separation component, a No. 2 magnetic separation component and a conveying and feeding component are installed. The No. 1 magnetic separation component and the No. 2 magnetic separation component are used to remove iron from the material in the conveying and feeding component, specifically quartz sand.

[0032] In this embodiment, the No. 1 magnet assembly adopts a contact type iron removal method. Specifically, the No. 1 magnetic separation assembly includes a semi-magnetic roller 12 rotatably connected to the base 11, and the base 11 is equipped with a No. 1 motor 13 for driving the semi-magnetic roller 12 to rotate. The No. 1 motor 13 is connected to the semi-magnetic roller 12 through a reducer.

[0033] The conveying and feeding assembly includes a No. 1 mounting plate 21 fixed to the base 11 through a No. 1 bracket, and a plurality of No. 1 rollers are rotatably connected between the front and rear No. 1 mounting plates 21, and a No. 1 conveyor belt 22 is connected between the No. 1 rollers. The No. 1 mounting plate 21 is provided with a No. 2 motor 23 for driving the No. 1 conveyor belt 22 to rotate, and the right edge of the No. 1 conveyor belt 22 does not exceed the right side of the semi-magnetic roller 12, so that the material on the No. 1 conveyor belt 22 can be delivered to the semi-magnetic roller 12 and de-ironed.

[0034] The No. 2 magnetic separation component is a non-contact iron removal method. Specifically, the No. 2 magnetic separation component includes a No. 2 mounting plate 31 fixed on the No. 1 mounting plate 21. The No. 2 mounting plate 31 is rotatably connected with a full magnetic roller 32 and a No. 2 roller distributed on the left and right. A No. 2 conveyor belt 33 is connected between the full magnetic roller 32 and the No. 2 roller. The No. 2 conveyor belt 33 extends to the right side of the base 11 so that the iron material attracted by the full magnetic roller 32 can be sent out. The No. 2 mounting plate 31 is equipped with a No. 3 motor 35 for driving the No. 2 roller to rotate.

[0035] When removing iron from materials, the staff energizes the No. 2 motor 23, the No. 1 motor 13, and the No. 3 motor 35. At this time, the upper edges of the No. 2 conveyor belt 33 and the No. 1 conveyor belt 22 move to the right, and the semi-magnetic roller 12 rotates clockwise.

[0036] After that, the staff puts the material on the No. 1 conveyor belt 22. When the material passes under the No. 1 conveyor belt 22 and continues to the right, it will undergo iron removal. That is, the iron in the material will be attracted by the full-magnetic roller 32 and transported to the right by the No. 2 conveyor belt 33. Finally, the iron will be unloaded at the right edge of the No. 2 conveyor belt 33.

[0037] After the material has been iron-removed once, it continues to move to the right on the No. 1 conveyor belt 22 until it is dumped onto the semi-magnetic roller 12. The clockwise rotating semi-magnetic roller 12 will absorb the iron material, and the iron material will fall after it is away from the magnetic area in the semi-magnetic roller 12, thereby performing a secondary iron removal. The iron material falling from the semi-magnetic roller 12 and the material falling after being dumped onto the semi-magnetic roller 12 will be distributed left to right. In order to further separate the two, a partition 51 is also provided in the base 11. The partition 51 is inclined to the lower left and close to the semi-magnetic roller 12. The iron material and the material will fall on the left and right sides of the partition 51 respectively.

[0038] It should be noted that the No. 1 conveyor belt 22 is a skirt conveyor belt (not shown in the figure) to prevent material from spilling. The staff can connect other conveyor belts or hoppers to independently collect the material after iron removal and the iron material thrown out on the left and right sides of the material. This is a conventional setting in the prior art and will not be repeated here.

[0039] In the second embodiment of the double magnetic separator, it also includes a smoothing plate 41, which is close to the upper edge of the No. 1 conveyor belt 22 and has a certain distance therefrom. The function of the smoothing plate 41 is to smooth the material being transported on the No. 1 conveyor belt 22 to prevent its local area from being too thick, which affects the iron removal effect.

[0040] The installation method of the smoothing plate 41 is as follows: a horizontal plate 42 is fixed between the second mounting plate 31, and a vertical rod connected to the horizontal plate 42 is installed on the upper side of the smoothing plate 41. In this embodiment, the smoothing plate 41 is located between the two skirts inside the first conveyor belt 22 to avoid interference with the skirts.

[0041] In addition, in order to make the spacing between the smoothing plate 41 and the No. 1 conveyor belt 22 adjustable, the vertical rod is designed to pass through the horizontal plate 42 upward and be able to slide up and down relative to the horizontal plate 42. In addition, a plurality of pin holes equidistantly distributed up and down are provided in the vertical rod, and pins inserted into the pin holes are screwed into the horizontal plate 42. The staff can unscrew the pins and adjust the upper and lower positions of the vertical rod and the smoothing plate 41, and then screw the pins into the sockets at the corresponding positions. The pins are threadedly connected to the horizontal plate 42.

[0042] In this embodiment, the latch is a bolt for ease of use.

[0043] The smoothing plate 41 is tilted downward to the left to smooth the material and avoid jamming.

[0044] In the third embodiment of the double magnetic separator, in order to facilitate the loading work, the conveying and feeding assembly is of a climbing machine style, that is, the No. 1 mounting plate 21 extends to the left to the left side of the base 11 and then tilts to the lower left. There are three No. 1 rotating rollers, which are respectively arranged on the rightmost, leftmost and bending part of the No. 1 mounting plate 21. The bending part of the No. 1 mounting plate 21 is also rotatably connected to a receiving roller, and the receiving roller lifts the lower edge of the No. 1 conveyor belt 22 to avoid the No. 1 conveyor belt 22 being triangular.

[0045] In addition, a plurality of No. 2 brackets are installed at the lower edge of the No. 1 mounting plate 21 on the left side of the base 11.

[0046] It should be noted that when the semi-magnetic roller 12 rotates, the magnetic area therein remains unchanged compared to the base 11 to perform iron removal. This is a prior art and will not be described in detail here.

[0047] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in this field within the scope of the present invention are included in the patent scope of the present invention.
