Description

Technical Field

[0001] The utility model belongs to the technical field of screening machines and relates to a crushing magnetic pulley screening device. Background Art

[0002] Magnetic screening machine is a kind of equipment that uses the characteristics of magnetic materials to separate and screen materials. It separates magnetic materials from the mixture through the action of magnetic field. Magnetic screening machine is widely used in mining, metallurgy, building materials, chemical industry, food and other industries, and is often used to separate and screen materials such as iron ore, coal, magnetic ore, and recycled metal.

[0003] The prior art has the following technical defects:

[0004] Common magnetic screening machines only have a single magnetic roller. When screening materials, a large amount of materials pass through a single magnetic roller, and the processing capacity of a single magnetic roller is relatively limited. It cannot meet the precise screening requirements of all particle sizes, resulting in unsatisfactory separation effects. At the same time, when processing some raw materials with high humidity and easy to agglomerate, the magnetic screening machine cannot effectively separate the agglomerated materials, and the agglomerated materials will form lumps, making it impossible for the magnetic roller to effectively adsorb and separate these agglomerated magnetic materials, reducing the separation effect of the magnetic material. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a crushing magnetic pulley screening device.

[0006] The crushing magnetic pulley screening device described in the utility model comprises a screening machine and a feed bin, the feed bin is connected to the top of the screening machine, a feed plate is installed inside the screening machine, a screening mechanism is arranged on the front side of the screening machine, and a crushing mechanism is arranged inside the feed bin; the screening mechanism comprises a servo motor and a support member fixedly connected to the screening machine, two magnetic rollers are rotatably connected to the support member, the two magnetic rollers are respectively connected to a double-groove transmission wheel and a single-groove transmission wheel, an output rod of the servo motor is connected to an output wheel, and the output wheel, the double-groove transmission wheel and the single-groove transmission wheel are all connected by a transmission belt.

[0007] Working process or working principle:

[0008] During operation, the material is put into the feed bin for crushing. After the material is crushed, it will slide onto the discharge plate. As the discharge plate tilts, the material slides onto the magnetic roller. Then the servo motor will drive the output rod and the output wheel to rotate. The rotation of the output wheel can simultaneously drive the double-groove transmission wheel and the single-groove transmission wheel to rotate through the transmission belt, and at the same time drive the two magnetic rollers to rotate. The rotation of the two magnetic rollers can adsorb and screen the magnetic materials in the material in turn, thereby increasing the coverage of the magnetic field and the area of ​​magnetic action, thereby enhancing the separation effect and improving the screening quality.

[0009] The crushing mechanism includes a crushing roller, a gear and a rotating motor. The crushing roller is rotatably connected to the inside of the feed bin. The gear is connected to the crushing roller in a one-to-one correspondence. Two adjacent gears are meshed with each other. The rotating motor is fixedly installed on the top of the screening machine, and the output end of the rotating motor is connected to the crushing roller.

[0010] The inner wall of the screening machine is fixedly connected to a support plate, and a plurality of springs are arranged on the support plate. The top of each spring is fixedly connected to a feed plate, and a vibration motor is installed at the bottom of the feed plate. The operation of the vibration motor will vibrate the feed plate and drive the spring to shake on the support plate. When the feed plate shakes, the material on the feed plate can slide down quickly to avoid the accumulation of material on the feed plate.

[0011] An inclined plate is fixedly connected to the inner side of the support member, and the inclined plate is located between the two magnetic rollers. After the top magnetic roller screens the raw materials, the raw materials can slide accurately onto the lower magnetic roller for secondary screening under the auxiliary guidance of the inclined plate, thereby preventing the raw materials from being thrown away by the top magnetic roller and unable to be screened for the second time.

[0012] A reinforcement plate is fixedly connected to one side of the screening machine, and the servo motor is fixedly installed on the reinforcement plate. The reinforcement plate can provide additional support and fixation to ensure the stability and safety of the bottom of the servo motor and prevent the servo motor from loosening or falling off during operation.

[0013] The surface of the magnetic roller is evenly distributed with a number of convex strips. Providing the convex strips on the surface of the magnetic roller can change the movement trajectory of the material on the magnetic roller and prevent the material from tilting or deviating due to inertia, thereby helping to maintain the uniform distribution of the material in the magnetic field and improve the separation effect.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] When the utility model screens the material, the material is first added into the screening machine from the feed bin, and the agglomerated material added into the feed bin is crushed to prevent the material from agglomerating and failing to effectively separate the magnetic material inside. After the material is crushed, it will slide along the discharge plate to the magnetic roller on the top, and the two magnetic rollers rotate at the same time. Under the adsorption of the two magnetic rollers, the magnetic material in the material is screened for a second time, thereby improving the screening effect of the magnetic material.

After the top magnetic roller 4 screens the raw materials, the raw materials can slide down accurately to the lower magnetic roller 4 for secondary screening under the auxiliary guidance of the inclined plate 18, so as to prevent the raw materials from being thrown away by the top magnetic roller 4 and unable to enter Secondary screening is performed; a reinforcement plate 19 is fixedly connected to one side of the screening machine 1, and the servo motor 7 is fixedly installed on the reinforcement plate 19.

[0024] During operation, the material is first added into the screening machine 1 from the feed bin 2, and the rotating motor 13 is operated at the same time. The rotating motor 13 drives the crushing roller 11 to rotate so as to crush the material to prevent the agglomerated material from reducing the magnetization degree and magnetic separation effect of the magnetic material. By crushing and breaking up the agglomerates, the magnetic material can be exposed to its magnetic properties again, thereby improving the effect of magnetic separation.
