Description

Technical Field

[0001] This utility model relates to the field of biomass fuel production and processing technology, and in particular to a magnetic separation device for biomass fuel transportation. Background Technology

[0002] Biomass fuel production typically begins by collecting raw materials such as agricultural and forestry waste, crushing them to a suitable particle size, drying them to remove excess moisture, and finally molding them into pellet or block fuel, which is widely used in heating, power generation, and other fields.

[0003] However, in the initial processing stage of biomass fuel, raw materials often contain tiny magnetic particles such as rust and iron powder. These impurities not only affect the quality and combustion efficiency of biomass fuel, but may also cause wear and damage to subsequent forming and combustion equipment. Existing magnetic separation devices are inefficient in removing tiny magnetic particles, and suffer from problems such as missed selection and incomplete separation, making it difficult to meet production needs. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to provide a magnetic separation device for biomass fuel transportation, which can effectively remove tiny magnetic particles and reduce magnetic impurities.

[0006] To achieve the above objectives, this utility model proposes a magnetic separation device for biomass fuel transportation, including a magnetic separation box and a feeding mechanism and a magnetic separation mechanism disposed inside the magnetic separation box. The magnetic separation mechanism is disposed at the discharge end of the feeding mechanism and includes a magnetic separation belt, a strong magnetic plate, and a magnetic material cleaning roller. The magnetic separation belt is disposed at the discharge end of the feeding mechanism, the strong magnetic plate is disposed inside the magnetic separation belt, and the magnetic material cleaning roller is disposed at the bottom of the magnetic separation belt.

[0007] Furthermore, the strong magnetic plate includes a permanent magnet plate or an electromagnetic plate, the strong magnetic plate is in contact with the inner wall of the magnetic separation belt, an eccentric wheel is provided below the strong magnetic plate, a crank is provided between the eccentric wheel and the strong magnetic plate, and magnetic plate guide sliders are provided on both sides of the strong magnetic plate.

[0008] Furthermore, the magnetic separation belt includes a magnetic rubber belt, and a magnetic separation belt drive roller is provided on the inner side of the magnetic separation belt. A magnetic separation belt drive motor is provided at one end of the magnetic separation belt drive roller to drive its rotation.

[0009] Furthermore, the feeding mechanism includes a feeding nozzle and a feeding conveyor belt, wherein the feeding nozzle is disposed at the feeding end of the magnetic separator, the feeding conveyor belt is disposed inside the feeding end, and the discharge end of the feeding conveyor belt is located above the magnetic separator belt.

[0010] Furthermore, the outer surface of the feeding conveyor belt is provided with a partition, the inner side of the feeding conveyor belt is provided with a conveyor belt drive roller, and one end of the conveyor belt drive roller is provided with a feeding drive motor to drive its rotation.

[0013] Beneficial effects: This utility model sets up a magnetic separation mechanism inside the magnetic separator box. When biomass material is fed into the magnetic separator belt by the feeding mechanism, the strong magnetic plate at the bottom of the magnetic separator belt strongly attracts the tiny magnetic particles, causing the magnetic particles to be quickly adsorbed onto the surface of the magnetic separator belt. Because the magnetic separator belt is magnetic, the magnetic particles will not easily detach during the material transmission process. Subsequently, the non-magnetic material on the magnetic separator belt is poured out, and the magnetic particles on the surface of the magnetic separator belt are swept off by the rotating magnetic material cleaning roller, making the surface of the magnetic separator belt clean again and allowing for repeated recycling.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] The magnetic separator for biomass fuel transport according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0021] like Figure 1 , Figure 2 As shown, the magnetic separation device for biomass fuel transportation provided in this embodiment of the present invention includes a magnetic separation box 1 and a feeding mechanism 2 and a magnetic separation mechanism 3 disposed inside the magnetic separation box 1.

[0022] The magnetic separation mechanism 3 is located at the discharge end of the feeding mechanism 2. The magnetic separation mechanism 3 includes a magnetic separation belt 33, a strong magnetic plate 34, and a magnetic cleaning roller 321. The magnetic separation belt 33 is located at the discharge end of the feeding mechanism 2, the strong magnetic plate 34 is located inside the magnetic separation belt 33, and the magnetic cleaning roller 321 is located at the bottom of the magnetic separation belt 33. A cleaning roller motor 32 is provided at one end of the magnetic cleaning roller 321.

[0023] Specifically, when the magnetic separator of this application is in use, the biomass material is first fed into the magnetic separator belt 33 through the feeding mechanism 2. As the magnetic separator belt 33 rotates, it drives the material to move. When the material reaches the top of the strong magnetic plate 34, the strong magnetic plate 34 at the bottom of the magnetic separator belt 33 forms a strong attraction to the tiny magnetic particles, causing the magnetic particles to be quickly adsorbed onto the surface of the magnetic separator belt 33. Furthermore, during the material transport process driven by the magnetic separator belt 33, since the magnetic separator belt 33 is magnetic, the magnetic particles on the surface of the magnetic separator belt 33 will not easily detach. Subsequently, the magnetic separator belt 33 pours out the non-magnetic material.

[0024] Subsequently, the magnetic particles adhere to the surface of the magnetic separator belt 33 and continue to move. When the magnetic particles pass the position of the magnetic material cleaning roller 321, the magnetic material cleaning roller 321 rotates at high speed to sweep the magnetic particles off, making the surface of the magnetic separator belt 33 clean again, and the magnetic separator belt 33 can be reused repeatedly.

[0025] In one embodiment of this utility model, such as Figure 2 As shown, the strong magnetic plate 34 includes a permanent magnet plate or an electromagnetic plate. The strong magnetic plate 34 is in contact with the inner wall of the magnetic separation belt 33. An eccentric wheel 35 is provided below the strong magnetic plate 34. A crank 351 is provided between the eccentric wheel 35 and the strong magnetic plate 34. Magnetic plate guide sliders 341 are provided on both sides of the strong magnetic plate 34.

[0026] Specifically, in order to fully separate the magnetic particles on the magnetic separator belt 33 from the biomass material, during the material transmission process of the magnetic separator belt 33, the eccentric wheel 35 rotates, driving the crank 351 to move. The crank 351 drives the strong magnetic plate 34 to move up and down repeatedly, thereby creating a oscillating and bumping effect on the material on the magnetic separator belt 33. This causes the magnetic particles mixed in the material to tumble continuously during transmission, and the magnetic particles are immediately and firmly adsorbed after contacting the magnetic separator belt 33, achieving the effect of fully separating them from the material.

[0027] In one embodiment of this utility model, such as Figure 2 As shown, the magnetic separator belt 33 includes a magnetic rubber belt, and a magnetic separator belt drive roller 36 is provided on the inner side of the magnetic separator belt 33. A magnetic separator belt drive motor 31 is provided at one end of the magnetic separator belt drive roller 36 to drive its rotation.

[0028] Specifically, the magnetic rubber material of the magnetic separator belt 33 can not only adsorb magnetic particles, but also has a certain elasticity, so that the magnetic separator belt 33 has flexible elastic tension when the strong magnetic plate 34 vibrates up and down, and can also ensure anti-slip function, so as to ensure stable material transmission and stable engagement between the magnetic separator belt drive roller 36 and the magnetic separator belt 33.

[0029] In one embodiment of this utility model, such as Figure 2 As shown, the feeding mechanism 2 includes a feeding nozzle 21 and a feeding conveyor belt 22. The feeding nozzle 21 is located at the feeding end of the magnetic separator 1, and the feeding conveyor belt 22 is located inside the feeding end. The discharge end of the feeding conveyor belt 22 is located above the magnetic separator belt 33.

[0030] The outer surface of the feeding conveyor belt 22 is provided with a partition 23, and the inner side of the feeding conveyor belt 22 is provided with a conveyor belt drive roller 27. One end of the conveyor belt drive roller 27 is provided with a feeding drive motor 24 that drives it to rotate.

[0031] Specifically, during the biomass material feeding process, the material is placed on the feeding conveyor belt 22 and evenly separated by the partition 23 during the transmission process. When the material on the feeding conveyor belt 22 is poured onto the magnetic separator belt 33, it will be more uniform.

[0032] In one embodiment of this utility model, such as Figure 2 As shown, a spiral brush 26 is provided at the bottom of the feeding conveyor belt 22. The spiral spacing of the spiral brush 26 is the same as the spacing between the partitions 23, which reduces direct contact with the top of the partitions 23 and allows for better rotation and cleaning inside the partitions 23. A spiral brush drive motor 25 is provided on one side of the spiral brush 26 to drive its rotation, and a spiral brush support turntable 261 is provided on the other side of the spiral brush 26.

[0033] Specifically, during the process of feeding conveyor belt 22 returning the material after it has been dumped, the spiral brush 26 at its bottom is driven to rotate by spiral brush drive motor 25. During the rotation of spiral brush 26, the material remaining on the inside of partition 23 is cleaned, reducing material residue during the return process.

[0034] In one embodiment of this utility model, such as Figure 2 As shown, a demagnetizing material hopper 37 is provided below the discharge end of the magnetic separator belt 33, a magnetic material hopper 322 is provided at the bottom of the magnetic material cleaning roller 321, a cleaning material hopper 28 is provided below the spiral brush 26, and a hopper gate 4 corresponding to the demagnetizing material hopper 37, the magnetic material hopper 322 and the cleaning material hopper 28 is provided on one side of the magnetic separator box 1.

[0035] Specifically, during the magnetic separation process, the non-magnetic material poured out by the magnetic separator belt 33 first enters the demagnetizing material discharge hopper 37. The magnetic particles adsorbed by the magnetic separator belt 33 are swept off the surface of the magnetic separator belt 33 by the high-speed rotation of the magnetic cleaning roller 321, and then centrifugally thrown out at high speed, finally falling into the magnetic material discharge hopper 322. The spiral brush 26 throws the cleaned material out to the cleaning material discharge hopper 28. Finally, the material in each discharge hopper can be taken out by opening the discharge hopper door 4.

[0036] To clearly illustrate the above embodiments, refer to Figure 1 and Figure 2 The working principle of the magnetic separation device for biomass fuel transmission of this utility model is as follows: When using the magnetic separation device of this application, the biomass material is first placed on the feeding conveyor belt 22, and is evenly separated by the partition 23 during the transmission process. Then the feeding conveyor belt 22 evenly pours the material onto the magnetic separation belt 33.

[0037] After the material arrives on the magnetic separator belt 33, the eccentric wheel 35 rotates, driving the crank 351 to move. The crank 351 drives the strong magnetic plate 34 to move up and down repeatedly, thereby creating a oscillating and bumping effect on the material on the magnetic separator belt 33. This causes the magnetic particles mixed in the material to tumble continuously during transmission. When the magnetic particles come into contact with the magnetic separator belt 33, they are immediately and firmly adsorbed, and the magnetic particles are fully separated from the material.

[0038] Subsequently, the magnetic separator 33 pours the non-magnetic material into the demagnetizing material hopper 37. The magnetic separator 33 adsorbs magnetic particles and passes them through the magnetic material cleaning roller 321. The magnetic material cleaning roller 321 rotates at high speed to sweep out the magnetic material on the surface of the magnetic separator 33 and centrifugally throws it into the magnetic material hopper 322. The spiral brush 26 throws the cleaned material into the cleaning material hopper 28, so that the surface of the magnetic separator 33 is cleaned again during the return process, and the magnetic separator 33 can be reused repeatedly.

[0039] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
