[0027] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0028] Example

[0029] like Figures 1-9 As shown, a mining vibrating magnetic separator includes: a screen frame 1, a screen cover 101 installed on the top of the screen frame 1, a hopper 102 installed on one side of the top of the screen cover 101, a screening chamber 103 opened inside the screen cover 101 and communicating with the hopper 102, a magnetic separation component disposed inside the screening chamber 103, the magnetic separation component including: a magnetic separation rod 2, a concave support block 201, a limiting screw hole 202, a fixing screw hole 203 and a positioning screw 204, and a disassembly and assembly component disposed between the screen frame 1 and the screen cover 101, the disassembly and assembly component including: a support 3, a locking lug 301, a fixing seat 302, a wrench 303, a locking pull rod 304 and a handle 305.

[0030] The two sides of the inner wall of the screening cavity 103 are provided with support blocks 104, the support blocks 104 are provided with stainless steel screens 105 fixed by bolts, the inside of the screening cavity 103 is divided into an upper screening cavity and a lower screening cavity by the stainless steel screens 105, one side of the bottom of the screening cavity 103 is provided with a discharge bin a 106 communicated with the upper screening cavity, and one side of the bottom of the screening cavity 103 is provided with a discharge bin b 107 communicated with the lower screening cavity. When the ore is screened, the ore is added to the inside of the screening cavity 103 from the discharge hopper 102. Since the inside of the screening cavity 103 is divided into the upper screening cavity and the lower screening cavity by the stainless steel screens 105, the added ore falls on the stainless steel screens 105, and the screening treatment of the ore is performed through the stainless steel screens 105. The ore larger than the mesh of the stainless steel screens 105 is blocked on the stainless steel screens 105, that is, located in the upper screening cavity, and the ore with large particles can be discharged and collected through the discharge bin a 106. The ore smaller than the mesh of the stainless steel screens 105 falls into the lower screening cavity from the stainless steel screens 105, and the ore with small particles can be discharged and collected through the discharge bin b 107.

[0031] The two sides of the bottom of the screen frame 1 are provided with motor mounting plates 4 fixed by bolts, the outer ends of the motor mounting plates 4 are provided with vibration motors 401, and the motor mounting plates 4 are provided with reinforcing ribs 402 between the vibration motors 401. After the ore is discharged into the inside of the screening cavity 103 and falls on the stainless steel screens 105, the vibration motors 401 are started to work. The vibration motors 401 generate vibration force on the screen frame 1, accelerate the screening speed of the ore on the stainless steel screens 105, and make the screened ore be discharged to the discharge bin a 106 and the discharge bin b 107 under the action of the vibration force, so as to avoid the blockage in the upper screening cavity and the lower screening cavity.

[0032] The inside of the screening cavity 103 is provided with four magnetic rods 2, the two sides of the inner wall of the screening cavity 103 are provided with a plurality of concave blocks 201 matched with the magnetic rods 2, the two ends of the four magnetic rods 2 are provided with limiting screw holes 202, the inside of the concave blocks 201 is provided with fixed screw holes 203 at the bottom end, and the limiting screw holes 202 are provided with positioning screw rods 204 screwed therein. After the ore is discharged into the inside of the screening cavity 103, the ore contacts the magnetic rods 2 in the inside of the screening cavity 103. The magnetic minerals mixed in the ore can be separated and magnetically attracted by the magnetic rods 2, so that the magnetic minerals can be magnetically attracted and fixed on the magnetic rods 2, the magnetic separation efficiency of the magnetic minerals in the ore can be improved, and the problem of low recovery rate of the magnetic minerals in the existing magnetic separator is solved.

[0033] The screen frame 1 is equipped with fixed brackets 5 on both sides of its outer end. The fixed brackets 5 are provided with a support base 6 at the bottom. Two convex spring seats 7 are installed at the bottom of the fixed brackets 5 and the top of the support base 6. An alloy steel spring 8 is installed between the two convex spring seats 7. When the vibrating motor 401 generates vibration force on the screen frame 1 to vibrate and screen the ore, the alloy steel spring 8 installed between the screen frame 1 and the support base 6 provides stable support for the screen frame 1 and ensures that the screen frame 1 has good elastic vibration, so that the ore inside the screen frame 1 can be quickly discharged during the screening process, further preventing the screen chamber 103 from being blocked.

[0034] Among them, three supports 3 are fixedly installed on both sides of the outer end of the screen cover 101 by bolts, and locking lugs 301 are installed on the outer ends of the three supports 3. Three fixed seats 302 are fixedly installed on both sides of the outer end of the screen frame 1 by bolts. A wrench 303 is rotatably connected to the end of each of the three fixed seats 302. A locking pull rod 304 with a "U" shaped structure is rotatably connected to the top of the wrench 303 through a rotating shaft. Handles 305 are installed on both sides of the top of the screen cover 101.

[0035] When using the screen frame 1, place the screen cover 101 on top of the screen frame 1 and tighten it to seal the screen frame 1. At this time, the supports 3 on both sides of the outer end of the screen cover 101 are aligned with the fixing seats 302 on both sides of the outer end of the screen frame 1. Grasp the wrench 303 and turn it upward, and rotate the locking lever 304 to lock it onto the locking lug 301. Then press the wrench 303 downward to lock the locking lever 304 and the locking lug 301, thereby fixing the screen cover 101 on top of the screen frame 1. To prevent ore from falling out during the screening process inside the screen frame 1, after the ore is screened and discharged, and the magnetic minerals are magnetically fixed on the magnetic separator 2, grab the wrench 303 and flip it upwards, and rotate the locking lever 304 to remove it from the locking lug 301, so that the locking lever 304 and the locking lug 301 are released from the locking limit. Grab the handle 305 to remove the screen cover 101 from the top of the screen frame 1, so that the entire screen chamber 103 is exposed.

[0036] Then, use a screwdriver to loosen and remove the positioning screw 204 from the fixing screw hole 203 and the limiting screw hole 202. Remove the magnetic separator 2 from the concave support block 201 to facilitate the removal of the magnetic separator 2 from the screen chamber 103. This will clean the magnetic minerals that are magnetically fixed to the magnetic separator 2, preventing them from affecting the normal use of the magnetic separator 2. The screen cover 101 and the screen frame 1 can be flexibly disassembled and reassembled, allowing for quick replacement of the magnetic separator 2 after it is worn or damaged.

[0037] Among them, the wrench 303 is fitted with an anti-slip sleeve 306, which is made of rubber material. When the wrench 303 is used, the anti-slip sleeve 306 on the outside of the wrench 303 can increase the friction between the hand and the hand, and prevent the hand from slipping on the wrench 303.

[0038] Working principle:

[0039] When the ore is screened, the ore is added from the lower hopper 102 to the inside of the screening cavity 103. Since the inside of the screening cavity 103 is divided into an upper screening cavity and a lower screening cavity by the stainless steel screen 105, the added ore falls on the stainless steel screen 105, and the ore is screened by the stainless steel screen 105. The ore larger than the mesh of the stainless steel screen 105 is blocked on the stainless steel screen 105, that is, in the upper screening cavity. The ore with a large particle size can be discharged and collected through the discharge bin a 106. The ore smaller than the mesh of the stainless steel screen 105 falls into the lower screening cavity from the stainless steel screen 105, and the ore with a small particle size can be discharged and collected through the discharge bin b 107. The vibration motor 401 is started to work, and the vibration motor 401 generates a vibration force on the screen frame 1 to accelerate the screening speed of the ore on the stainless steel screen 105, so that the screened ore can be discharged to the discharge bin a 106 and the discharge bin b 107 under the action of the vibration force, avoiding the blockage of the inside of the upper and lower screening cavities.

[0040] After the ore is discharged into the inside of the screening cavity 103, the ore contacts the magnetic selection rod 2 in the inside of the screening cavity 103. The magnetic selection rod 2 can magnetically separate the magnetic minerals mixed in the ore, so that the magnetic minerals can be magnetically fixed on the magnetic selection rod 2, which can improve the magnetic separation efficiency of the magnetic minerals in the ore and solve the problem of low recovery rate of magnetic minerals in the existing magnetic separator. After the magnetic minerals are magnetically fixed on the magnetic selection rod 2, the wrench 303 is turned upward, the locking pull rod 304 is removed from the locking lug 301, the locking position between the locking pull rod 304 and the locking lug 301 is released, the handle 305 can be used to remove the screen cover 101 from the top of the screen frame 1, and the inside of the whole screening cavity 103 is exposed.

[0041] Then use a screwdriver tool to unscrew and remove the positioning screw 204 from the inside of the fixed screw hole 203 and the limiting screw hole 202, and disassemble the magnetic selection rod 2 from the concave block 201. The magnetic selection rod 2 can be disassembled and removed from the inside of the screening cavity 103, the magnetic minerals magnetically fixed on the magnetic selection rod 2 can be cleaned, the normal use of the magnetic selection rod 2 is avoided, and the screen cover 101 and the screen frame 1 can be flexibly disassembled. The magnetic selection rod 2 can be quickly replaced when it is worn or damaged.
