Description

Technical Field

[0001] The invention relates to the technical field of magnesium oxide production, in particular to self-cleaning raw material crushing and demagnetization equipment for magnesium oxide production. Background Art

[0002] Magnesium oxide exists in nature in the form of periclase and is the raw material for magnesium smelting. After being burned at a high temperature of more than 1000°C, it can be transformed into crystals, and when it rises to 1500-2000°C, it becomes dead-burned magnesium oxide (magnesia) or sintered magnesium oxide. The existing magnesium ore needs to be demagnetized after preliminary treatment. Since the ore contains different metal elements in nature, it cannot be directly processed and used, and further demagnetization treatment is required. The existing preliminary treatment of magnesium ore is to put the magnesium ore into a crusher for crushing, and then put it into the demagnetization equipment to separate magnesium and metal. The existing crushing and demagnetization equipment are usually not in the same space, which makes the process of processing magnesium ore lengthy and the feeding time between crushing and demagnetization is relatively long. And usually in the demagnetization equipment, a plurality of fixed magnetic bars are used to adsorb the metal in the magnesium ore, and the crushed magnesium ore is transported to the magnetic bars through the pipeline flow channel for washing, so that the magnetic bars adsorb the metal in the magnesium ore. Although the metal in the magnesium ore can be adsorbed, as the processing time increases, the metal debris accumulated in the magnetic bars becomes too thick, and the metal debris on the magnetic bars are easily accumulated as magnesium ore powder in the process of attraction, which reduces the discharge amount. The solution is to stop the machine for a period of time and manually clean the inside of the machine before continuing production, which increases the working time and is not conducive to long-term production. For this reason, we propose a self-cleaning magnesium oxide production raw material crushing and demagnetization equipment. Summary of the invention

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-12 The present invention provides a technical solution: a self-cleaning magnesium oxide production raw material crushing and demagnetization equipment, comprising a processing tank 1, and a feeding hopper is also provided on the side of the processing tank 1. Figure 1As shown, a demagnetizer 2 is fixedly installed at the bottom of the processing tank 1, a fixed base 4 is fixedly installed on one side of the bottom of the demagnetizer 2, a support plate 12 is fixedly installed on the fixed base 4, a second connecting disk 10 is rotatably connected to one side of the demagnetizer 2, and a first connecting disk 203 is rotatably connected to the other side of the demagnetizer 2, a reciprocating screw rod 22 is fixedly connected to the first connecting disk 203, one end of the reciprocating screw rod 22 is fixedly connected to a transmission gear 14, an inner-toothed rotating disk 11 is fixedly connected to one side of the second connecting disk 10, a transition gear 13 is arranged between the inner-toothed rotating disk 11 and the transmission gear 14, a support plate 12 is fixedly installed on the top of the fixed base 4, the transition gear 13 and the transmission gear 14 both rotate on the support plate 12, and a plurality of magnetic rods 21 are fixedly arranged at equal intervals on the first connecting disk 203, The second connection plate 10 is provided with a plurality of connection holes 15, one end of each of the magnetic rods 21 passes through the connection hole 15 and contacts the second connection plate 10, and the rotation tracks of the plurality of magnetic rods 21 pass over the bottom of the processing tank 1, a bearing 25 is fixedly connected to the middle of one side of the first connection plate 203, and a reciprocating screw rod 22 is fixedly connected to the inner ring of the bearing 25, and a sleeve ring 23 is slidably connected to each of the magnetic rods 21, and a connecting ring 24 is sleeved on the reciprocating screw rod 22, and each of the sleeve rings 23 is rollingly connected to the connecting ring 24, and a plurality of magnets 29 are equidistantly arranged on the other side of the demagnetizer 2, and the magnetic poles of the magnets 29 and the magnetic rods 21 are opposite, and the reciprocating screw rod 22 is slidably connected to the second connection plate 10, and when the magnesium ore is crushed inside the processing tank 1, it is immediately put into the demagnetizer 2 for further processing,Then, in the process of the magnesium ore contacting the magnetic rod 21, the metal has the same magnetic poles as the magnetic rod 21, which makes the magnetic rod 21 rotate. As the processing time increases, the magnetic rod 21 gradually accumulates metal from the outside and the gravity of one or more magnetic rods 21 becomes greater, which makes it easy for other magnetic rods 21 to rotate in the direction of the magnetic rod 21 with a relatively large thickness, so that multiple magnetic rods 21 can drive the first connecting disk 203 and the first connecting disk 203 to rotate during the processing process, wherein the first connecting disk 203 and the first connecting disk 203 are made of lightweight materials, so that the magnetic rod 21 is easy to rotate. When the first connecting disk 203 and the first connecting disk 203 rotate, the first connecting disk 203 can make one end of the multiple magnetic rods 21 have a contact point with the connecting hole 15, and at the same time, during the rotation of the second connecting disk 10, the inner tooth rotating disk 11 is rotated. When the inner tooth rotating disk 11 rotates During the movement, the transition gear 13 and the transmission gear 14 are meshed and transmitted on the fixed base 4, the transmission gear 14 and the reciprocating screw rod 22 are fixedly connected, and the reciprocating screw rod 22 is rotated on the inner ring of the bearing 25. During the rotation of the magnetic rod 21, only the outer ring of the bearing 25 follows the connection ring 24 to contact. During the rotation of each magnetic rod 21, each sleeve ring 23 is driven to roll on the outer ring of the connection ring 24, wherein the connection ring 24 adopts a groove design and is connected with the sleeve ring 23, and during the rotation of the reciprocating screw rod 22, the connection ring 24 can be driven to move and then the connection ring 24 drives the sleeve ring 23 to move on the magnetic rod 21, and the metal on the magnetic rod 21 is wiped off to the connection hole 15, and the metal is discharged to the outside as the second connection disk 10 rotates; when the connection ring 24 is located on one side of the connection ring 2, it can be manually assisted to rotate and reset the connection ring 24;, As a further solution, connecting holes 15 (not shown) can be opened on the transfer plate 3 and the first connecting plate 203 at the same time. In this way, without the need for human assistance, the rotation of the reciprocating screw rod 22 will also cause the connecting ring 24 to reciprocate on the magnetic rod 21, thereby pushing out the metal on the magnetic rod 21 and saving labor costs.

[0018] It is worth mentioning that when the multiple magnetic bars 21 are rotating, the multiple magnets 29 located at the bottom of the demagnetizer 2 will approach a magnetic bar 21 that is rotating. The magnetic poles of the magnetic bar 21 and the magnet 29 are opposite, so that the magnet 29 will repel the metal on the magnetic bar 21, causing the metal in its outer circle to move to a position where the outer circle is away from the magnet 29, allowing the powder between the metals to flow out of the demagnetizer 2, preventing magnesium ore powder from being stuck between the metals in its outer circle, thereby improving the magnesium ore extraction rate and increasing the output.

[0019] Furthermore, a rotating disc 3 is fixedly installed on the other side of the first connecting disc 203, and a plurality of slide grooves 301 are equidistantly provided on the rotating disc 3, one end of each of the slide grooves 301 is close to the axis of the rotating disc 3 and the other end is toward the edge of the rotating disc 3, and each of the slide grooves 301 is slidably connected with a centering roller 302. When metal accumulates on the magnetic rod 21, the first connecting disc 203 and the rotating disc 3 rotate, and the centering roller 302 at the top slides on the slide groove 301 and moves to one end of the slide groove 301, which is used for the rotating disc 3 to assist the first connecting disc 203 in rotating. When the plurality of magnetic rods 21 rotate, the first connecting disc 203 will also drive the rotating disc 3 to rotate synchronously. During the rotation of the rotating disc 3, the centering roller 302 at the top moves so that the overall center of gravity will be shifted, so that the rotating disc 3 drives the first connecting disc 203 to rotate sustainably, thereby improving the rotation time of the reciprocating screw rod 22.

[0020] Furthermore, the diameter of one end of each connecting hole 15 facing the inside of the demagnetizer 2 is smaller than the opening size of the other end, so that it has a trumpet shape, which is used to discharge the metal material on the surface of the magnetic rod 21 to the outside of the demagnetizer 2, and facilitates the metal on the connecting hole 15 to be easily discharged to the outside of the demagnetizer 2 during the rotation of the second connecting disk 10.

[0021] Furthermore, a separation leak plate 20 is fixedly connected between the processing tank 1 and the demagnetizer 2. The separation leak plate 20 is S-shaped, with one end located at the top of the demagnetizer 2 and the other end located in the middle of one side of the inner wall of the demagnetizer 2. A fan 31 is fixedly installed on one side of the top of the demagnetizer 2. A straight panel 202 is provided on one end of the bottom side of the demagnetizer 2 that extends upward over the separation leak plate 20. The top of the straight panel 202 is connected to the demagnetizer 2 to form an inverted slope 201. A channel for conveying dust to the inside of the processing tank 1 is formed between the inverted slope 201, the straight panel 202 and the separation leak plate 20. The leakage hole of the separation leakage plate 20 is opened beside the inverted slope 201. When the bottom of the processing tank 1 is discharged, the fan 31 is turned on. The fan 31 blows the magnesium ore powder through the separation leakage plate 20, and the magnesium ore powder with relatively large weight and the powder with relatively small weight will be separated. The magnesium ore powder with relatively large weight will flow along the separation leakage plate 20 to the magnetic rod 21, and the powder with relatively small weight will be affected by the wind force and will be hit on the inverted slope 201 and the straight plate 202, causing rebound. After the powder rebounds, it is discharged upward by wind force, thereby improving the uniformity of the overall particles of the magnesium ore.

[0022] Furthermore, guide rails 28 are fixedly installed on both sides of the bottom of the demagnetizer 2, and a guide plate 30 is slidably connected between the two guide rails 28. Each of the magnets 29 is located between two adjacent guide plates 30. A spring 27 is connected between each of the guide plates 30 and the demagnetizer 2, and a force sensor 26 is fixedly connected to one of the guide plates 30; flow channel plates 3001 are arranged on both sides of each guide plate 30 toward the movement trajectory of the multiple magnetic rods 21, and the two flow channel plates 3001 located on the same guide plate 30 are stepped according to the distance between the side of the guide plate 30 and the movement trajectory of the magnetic rods 21. When the magnetic bar 21 absorbs the metal, it may contact the magnet 29 during the rotation. At this time, the flow plate 3001 of the guide plate 30 can be used to separate and push the metal on the magnetic bar 21. When the metal on a certain magnetic bar 21 rolls on the flow plate 3001, the flow plate 3001 allows the metal to move to a certain position of the magnetic bar 21, thereby assisting the magnet 29 to easily repel the metal on the magnetic bar 21, which is more conducive to pouring out the powder between the metals. The force sensor 26 can assist manual identification of whether the magnetic bar 21 rotates and the position of the magnetic bar 21, thereby determining.

[0023] Furthermore, an air suction hood 6 is suspended on the top of the processing tank 1, and a driving bevel gear 19 is fixedly connected to the bottom of the air suction hood 6; an inner tank 5 is fixedly connected to the top of the demagnetizer 2, and a dust ascending flow channel is formed between the inner tank 5 and the air suction hood 6; a collection frame 9 is fixedly installed on the bottom of the inner circle of the inner tank 5, and a multi-layer crushing trough 901 is opened in the inner circle of the collection frame 9; a distribution plate 7 is rotatably connected to the bottom of the inner tank 5, and the distribution plate 7 is made of a multi-layer plate-like structure stacked up and down, and a plurality of crushing plates 8 are equidistantly fixed on the outer circle of each layer of the plate-like structure, and the crushing plate 8 and the crushing trough 901 are slidably connected, and a connecting core 16 is fixedly connected to the top of the connecting core 16, and an inner bevel gear plate 17 is fixedly connected to the top of the connecting core 16, and the inner bevel gear plate 17 and the driving bevel gear 19 A plurality of transition bevel gears 18 are arranged in between; the material of the distribution plate 7 is made of lightweight material, and its top has a non-slip design. The magnesium ore enters the distribution plate 7 from the side feed hopper of the processing tank 1, and a motor is installed on the top of the suction hood 6 to discharge the dust flowing into the dust ascending flow channel to the outside. At the same time, when the suction hood 6 rotates, the driving bevel gear 19 drives the plurality of transition bevel gears 18 to rotate, and the rotation of the plurality of transition bevel gears 18 drives the inner bevel gear plate 17 to drive the connecting core 16 to rotate in a high-speed and low-torque manner. The connecting core 16 can drive the distribution plate 7 to rotate during the rotation process, and the distribution plate 7 allows the magnesium ore at the top thereof to be discharged into the multi-layer crushing trough 901 by centrifugal means so as to allow the rotating crushing plate 8 to be ground and crushed, thereby reducing the feeding time of the device.
