Description

An iron separation mechanism for composite powder production

Technical Field

The utility model relates to the technical field of iron powder separation, in particular to an iron separation mechanism for composite powder production.

Background Art

Composite powder refers to powder in which each particle is composed of two or more different components. In the process of coal mining and processing, it is often necessary to grind the ore and then carry out subsequent processing on the ground ore.

The inventor discovered in his daily work that some coal mine composite powders are mainly composed of coal mine ash, ore powder and iron powder. Coal is the core material of the composite powder contained in both coal mine ash and coal ore powder, which is the required material. Some iron powder mixed in them as impurities affects the properties of the overall composite powder. Therefore, it is necessary to design a device that can separate the iron powder from the composite powder.

Utility Model Content

The utility model aims to solve the shortcomings in the prior art and proposes an iron separation mechanism for composite powder production.

In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an iron selection mechanism for composite powder production, comprising a mounting frame, on which a conveyor belt is mounted, the conveyor belt is used to transmit mineral powder, the conveyor belt on the mounting frame is inclined, a baffle plate is provided on the side of the mounting frame located at the highest end of the conveyor belt, and a screening mechanism for adsorbing iron powder in the mineral powder transported by the baffle plate is installed in the mounting frame.

The effect achieved by the above components is: when the composite powder composed of coal powder and mineral powder is screened out to remove the iron powder mixed therein, the composite powder is first transported by a conveyor belt (the conveyor belt is an existing conventional powder conveying conveyor belt so it will not be described in detail here), the conveyor belt carries the composite powder to a high place and then throws it down, and the falling composite powder is blocked by a baffle plate. The screening mechanism located at the bottom end of the baffle plate magnetically attracts the iron powder in the composite powder, and the remaining powder continues to fall. A cart can be set below to collect the fallen powder, thereby achieving the effect of quickly screening the iron powder.

Preferably, the screening mechanism includes a bracket fixed to the side wall of the mounting frame, the interior of the bracket is fixedly connected to a shaft rod, the surface of the shaft rod is fixedly connected to a magnetic sheet via a connecting rod, wherein a sleeve is sleeved on the surface of the shaft rod and the magnetic sheet, the port of the sleeve is rotatably connected to the bracket by means of a bearing, and the center axis of the sleeve coincides with the shaft rod.

Preferably, the sleeve is a plastic sleeve, and a plurality of arc buckets are evenly and fixedly connected to the surface of the sleeve.

The effect achieved by the above components is as follows: the magnetic sheet is set on the surface of the shaft through a connecting rod. When the composite powder falls onto the sleeve, it first contacts the side of the sleeve close to the magnetic sheet. At this time, the iron powder is adsorbed on the surface of the sleeve. As the sleeve rotates, the iron powder adsorbed between the two arc buckets on the sleeve surface gradually moves away from the magnetic sheet as the sleeve rotates. Except for the iron powder, the remaining powder falls normally under the action of gravity. When the sleeve rotates to the side farthest from the magnetic sheet, the iron powder sticks to the surface of the sleeve and falls because the magnetism is not sufficient to support it (a magnet can also be set externally at this position to collect the iron powder on the sleeve surface). The arc bucket is an arc-shaped baffle, and multiple arc buckets can disperse the material that falls on the surface of the sleeve.

Preferably, a motor is fixedly connected to the surface of the bracket, and the output shaft of the motor is meshed with a gear ring, wherein the gear ring is fixed to the port of the sleeve.

The effects achieved by the above components are as follows: the motor drives the sleeve to rotate on the surface of the bracket through the gear ring with the help of the bearing, and the rotating sleeve receives and transports the materials dropped from the baffle plate.

Preferably, a support leg is fixedly connected to one side of the material baffle plate, and the support leg is obliquely supported on the ground to support the material baffle plate.

Preferably, a vibration device for striking the gear ring is provided on the bracket.

The effect achieved by the above components is that by setting the vibration rotation, the sleeve can be struck and vibrated during the sleeve rotation process, thereby ensuring that the iron powder on the surface of the sleeve away from the magnetic sheet can be shaken off.

Preferably, the vibration device includes a cylinder fixedly connected to the surface of the bracket, a sliding rod is slidably connected to the inside of the cylinder, one end of the sliding rod is fixedly connected to a baffle, a spring is sleeved on the surface of the sliding rod, wherein the two ends of the spring are respectively fixedly connected to the baffle and the cylinder, and the surface of the gear ring is evenly and fixedly connected with convex strips, and the convex strips squeeze the sliding rod during the rotation of the gear ring.

The effect achieved by the above components is: when the sleeve rotates with the gear ring, the convex strips on the surface of the gear ring continuously squeeze the sliding rod, and the sliding rod is squeezed and pulled by the spring to slide. When the convex strips no longer squeeze the sliding rod, the sliding rod is reset under the elastic force of the spring and hits the gear ring, causing vibration. The vibration causes the iron powder on the side of the sleeve away from the magnetic sheet to fall off.

Preferably, a ball is rotatably connected to the end of the slide rod.

The effects achieved by the above components are as follows: the function of the rolling ball is to make rotational contact with the convex strips, to better contact the convex strips and to be squeezed by the convex strips.

Compared with the prior art, the advantages and positive effects of the utility model are:

In the utility model, the composite powder is first transported by a conveyor belt, which carries the composite powder to a high place and then throws it down (useless dust can be removed by air separation during the throwing process), and the falling composite powder is blocked by a baffle plate. The screening mechanism located at the bottom end of the baffle plate magnetically attracts the iron powder in the composite powder, and the remaining powder continues to fall. A cart can be arranged below to collect the fallen powder, thereby achieving the effect of quickly screening the iron powder.

When the composite powder composed of coal powder and mineral powder is screened to remove the iron powder doped therein, the composite powder is first transported through the conveyor belt 2 (wherein the conveyor belt 2 is an existing conventional conveyor belt 2 for powder conveying, so it will not be described in detail here), the conveyor belt 2 carries the composite powder to a high place and then throws it down, and the falling composite powder is blocked by the baffle plate 3, and the screening mechanism 5 located at the bottom end of the baffle plate magnetically attracts the iron powder in the composite powder, and the remaining powder continues to fall, and a cart can be provided below to collect the fallen powder, thereby achieving the effect of quickly screening the iron powder, and the screening mechanism 5 includes A bracket 51 is fixed to the side wall of the mounting frame 1, and a shaft 56 is fixedly connected inside the bracket 51. A magnetic piece 57 is fixedly connected to the surface of the shaft 56 through a connecting rod, wherein a sleeve 54 is sleeved on the surface of the shaft 56 and the magnetic piece 57, and the port of the sleeve 54 is rotatably connected to the bracket 51 by means of a bearing, the central axis of the sleeve 54 coincides with the shaft 56, the sleeve 54 is a plastic sleeve, and a plurality of arc buckets 55 are evenly and fixedly connected to the surface of the sleeve 54, and the magnetic piece 57 is arranged on the surface of the shaft 56 through a connecting rod. When the composite powder falls onto the sleeve 54, it first contacts the side of the sleeve 54 close to the magnetic piece 57, and at this time, the iron powder is adsorbed on the surface of the sleeve 54. As the sleeve 54 rotates, the iron powder adsorbed between the two arc buckets 55 on the surface of the sleeve 54 gradually moves away from the magnetic piece 57 as the sleeve 54 rotates, and the remaining powder except the iron powder falls normally under the action of gravity, and the iron powder is not supported by the magnetism when the sleeve 54 rotates to the side farthest from the magnetic piece 57. The bracket 51 is provided with a vibration device 6 for striking the gear ring 53, and the vibration device 6 is provided with a vibration rotation device 6 for striking the gear ring 53, and the vibration rotation device 6 is provided with a vibration rotation device 6 for striking the gear ring 53, and the vibration rotation device 6 is provided with a vibration rotation device 6 for striking the gear ring 53, and the vibration rotation device 6 is provided with a vibration rotation device 6 for striking the gear ring 53, and the vibration rotation device 6 is provided with a vibration rotation device 6 for striking the gear ring 53, and the vibration rotation device 6 is provided with a vibration rotation device 6 for striking the vibration sleeve 54 during the rotation of the sleeve 54, and the vibration rotation device 6 is provided with a vibration rotation device 6 for striking the vibration sleeve 54, and the vibration rotation device 6 is provided, and the vibration sleeve 54 is The cylinder 61 is connected to the surface of the bracket 51, and a slide bar 62 is slidably connected inside the cylinder 61. One end of the slide bar 62 is fixedly connected to a baffle 66. A spring 65 is sleeved on the surface of the slide bar 62, wherein both ends of the spring 65 are fixedly connected to the baffle 66 and the cylinder 61 respectively. The surface of the gear ring 53 is evenly fixedly connected with a convex strip 64. During the rotation of the gear ring 53, the convex strip 64 squeezes the slide bar 62. When the sleeve 54 rotates with the gear ring 53, the convex strip 64 on the surface of the gear ring 53 continuously squeezes the slide bar 62. The slide bar 62 is squeezed and the spring 65 slides. When the convex strip 64 no longer squeezes the slide bar 62, the slide bar 62 is reset under the elastic force of the spring 65 and hits the gear ring 53, thereby vibrating. The vibration allows the iron powder on the side of the sleeve 54 away from the magnetic sheet 57 to fall. The end of the slide bar 62 is rotatably connected with a rolling ball 63. The function of the rolling ball 63 is to be able to rotate in contact with the convex strip 64 to better contact the convex strip 64 and be squeezed by the convex strip 64.

Working principle: when the composite powder composed of coal powder and mineral powder is screened to remove the iron powder mixed therein, the composite powder is first transported by the conveyor belt 2 (the conveyor belt 2 is the existing conventional powder conveying conveyor belt 2, so it will not be described in detail here). The conveyor belt 2 carries the composite powder to a high place and then throws it down. The falling composite powder is blocked by the baffle plate 3. The screening mechanism 5 located at the bottom end of the baffle plate magnetically attracts the iron powder in the composite powder, and the remaining powder continues to fall. A cart can be set below to collect the fallen powder, thereby achieving rapid separation of the iron powder. The magnetic sheet 57 is arranged on the surface of the shaft 56 through the connecting rod. When the composite powder falls onto the sleeve 54, it first contacts the side of the sleeve 54 close to the magnetic sheet 57. At this time, the iron powder is adsorbed on the surface of the sleeve 54. As the sleeve 54 rotates, the iron powder adsorbed between the two arc buckets 55 on the surface of the sleeve 54 gradually moves away from the magnetic sheet 57 as the sleeve 54 rotates. Except for the iron powder, the remaining powder falls normally under the action of gravity. When the sleeve 54 rotates to the side farthest from the magnetic sheet 57, the iron powder is not sufficiently supported to stick to the magnetic sheet 57. The surface of the sleeve 54 is made to fall (a magnet can also be set outside at this position to collect iron powder on the surface of the sleeve 54), the arc bucket 55 is an arc-shaped baffle, and multiple arc buckets 55 can disperse the materials dropped on the surface of the sleeve 54. The motor 52 drives the sleeve 54 to rotate on the surface of the bracket 51 through the gear ring 53 with the help of the bearing. The rotating sleeve 54 receives and transports the materials dropped from the baffle plate 3. By setting the vibration rotation, the sleeve 54 can be knocked and vibrated during the rotation of the sleeve 54, thereby ensuring that the sleeve 54 is away from the magnetic sheet 57. The iron powder on one side of the surface can be shaken off. When the sleeve 54 rotates with the gear ring 53, the convex strips 64 on the surface of the gear ring 53 continuously squeeze the slide bar 62. The slide bar 62 is squeezed and pulls the spring 65 to slide. When the convex strips 64 no longer squeeze the slide bar 62, the slide bar 62 is reset under the elastic force of the spring 65 and hits the gear ring 53, thereby vibrating. The vibration causes the iron powder on the side of the sleeve 54 away from the magnetic sheet 57 to fall off. The function of the ball 63 is to be able to rotate in contact with the convex strips 64 to better contact the convex strips 64 and be squeezed by the convex strips 64.
