[0001] This application relates to the field of biomass fuel processing technology, and in particular to a purification device for biomass fuel processing and its method of use. Background Technology
[0002] The application of biomass fuel mainly refers to biomass briquettes, which are a new type of clean fuel that can be directly burned. This is made from agricultural and forestry waste as raw materials and processed through crushing, mixing, extrusion, drying and other processes to produce various shapes (such as blocks, pellets, etc.).
[0003] In existing equipment, after the material is crushed in the crushing mechanism, the crushed material is transported to the mixing mechanism to bind the crushed material together. Then, the mixed material is extruded and shaped by the extrusion mechanism, and then dried and discharged. However, the crushed material will generate dust, which easily adheres to the inner wall of the mixing mechanism when it enters the mixing mechanism. Over time, a large amount of dust accumulates on the inner wall of the mixing mechanism. Because the equipment will vibrate during use, the old dust adhering to the inner wall of the mixing mechanism may clump and fall off due to vibration and moisture, mixing into the newly processed material, causing product contamination and affecting the quality of subsequent molding (such as granulation). Summary of the Invention

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. When using the device, the material is put into the crushing mechanism for crushing. The crushed material is then transported to the dust removal mechanism. Because the crushed material will generate dust, in order to prevent the dust from entering the subsequent working process, the crushed material is removed by the dust removal mechanism. After dust removal, the crushed material is transported to the mixing mechanism for mixing. After mixing, the material is transported to the extrusion mechanism to be extruded into shape. After extrusion, the material is dried and discharged, which improves the working efficiency of the device.
[0015] 2. When using the device, the material enters the crushing box from the feed port. The first motor is started, and the first motor drives the cutting roller to cut and crush the material.

After crushing, the material enters the dust removal mechanism through the discharge port and conveying pipe, which improves the crushing of the material more thoroughly.
[0016] 3. During implementation, dust-laden material enters the dust collection box through the conveyor pipe and falls onto the positively charged filter plates. The dust particles agitated by the falling material repel each other due to their positive charge, with larger particles falling directly into the bottom dust collection box under gravity. The remaining fine dust particles flow to the dust inlet trough under the guidance of the fan and are firmly adsorbed by the negatively charged electrode plates, effectively preventing dust from entering subsequent processes. For cleaning, simply open the box door to remove the dust collection box and clear away large dust particles; loosen the top screws to remove the electrode plates and clean the fine dust adsorbed on their surfaces.

[0019] The present application will be further described in detail below with reference to the accompanying drawings.
[0020] Example, refer to Figures 1-3A purification device for biomass fuel processing includes a support frame 1, a crushing mechanism 2 for crushing materials, a mixing mechanism 3 for binding the crushed materials, a dust removal mechanism 4 for removing dust from the materials between the crushing mechanism 2 and the mixing mechanism 3, an extrusion mechanism 5 for shaping the mixed materials, and a drying mechanism 6 for drying the compressed materials. In operation, materials are crushed in the crushing mechanism 2, and the crushed materials are then transported to the dust removal mechanism 4 to remove dust, preventing it from entering subsequent processes. After dust removal, the crushed materials are transported to the mixing mechanism 3 for mixing, and then transported to the extrusion mechanism 5 for extrusion molding. Finally, the materials are dried and discharged, improving the device's efficiency.
[0021] The crushing mechanism 2 includes a crushing box 21, a first motor 22, and a cutting roller 23. The crushing box 21 is fixedly installed on the top surface of the support frame 1. The top and bottom surfaces of the crushing box 21 are respectively provided with a feeding port and a discharging port. The first motor 22 is fixedly installed on one side of the crushing box 21, with its output end extending through one side of the crushing box 21. The cutting roller 23 is located at the output end of the first motor 22. A conveying pipe 24 is provided at the discharging port of the crushing box 21 to transport the crushed material to the dust removal mechanism 4. When using the device, the material enters the crushing box 21 through the feeding port. By starting the first motor 22, the first motor 22 drives the cutting roller 23 to cut and crush the material. Alternatively, a linkage mechanism can be installed in the crushing box 21, and two cutting rollers 23 can be installed. The first motor 22 drives the linkage mechanism, which in turn drives the two cutting rollers 23 to rotate and crush the material. After crushing, the material enters the dust removal mechanism 4 through the discharging port and the conveying pipe 24, thus improving the thorough crushing of the material.
[0022] The dust removal mechanism 4 includes a dust collection box 41, a filter plate 42, a fan 43, an electrode plate 44, and a dust collection box 45. The dust collection box 41 is fixedly installed on the support frame 1. The conveying pipe 24 connects to the interior of the dust collection box 41 from the top surface. The filter plate 42 is inclinedly arranged on opposite sides inside the dust collection box 41 and tilted downwards. The conveying pipe 24 is located above the filter plate 42. The filter plate 42 carries a positive charge from an external circuit. The fan 43 is embedded inside the dust collection box 41. On one side of the dust collector 41, a dust inlet trough is provided on the side away from the fan 43. A connector slot is provided on the top surface of the dust collector 41 and connects to the dust inlet trough. An electrode plate 44 is disposed in the connector slot. A screw is provided on the top of the dust collector 41 and threadedly connected to one side of the electrode plate 44. The electrode plate 44 carries a negative charge from an external circuit. A dust collection box 45 is placed at the bottom of the dust collector 41, below the filter plate 42. One side of the dust collector 41 has an opening and a hinged door. During implementation, dust-laden material enters the dust collector 41 through the conveying pipe 24 and falls onto the positively charged filter plate 42. The dust agitated by the falling material repels each other due to its positive charge, with larger particles falling directly into the bottom dust collection box 45 under gravity. The remaining fine dust flows to the dust inlet trough under the guidance of the fan 43 and is firmly adsorbed by the negatively charged electrode plate 44, effectively preventing dust from entering subsequent processes. During cleaning, simply open the door to remove the dust collection box 45 and clean out large dust particles; loosen the top screws to remove the electrode plate 44 and clean out the fine dust adsorbed on its surface, making maintenance convenient and efficient.
[0023] The dust collection box 41 has an opening on one side, located at the bottom of the filter plate 42. The mixing mechanism 3 includes a mixing box 31, an ion fan 32, a spraying assembly 33, and a stirring assembly 34. The mixing box 31 is fixedly installed on the support frame 1. The mixing box 31 has a feed inlet on the side near the dust collection box 41. The bottom end of the filter plate 42 passes through the opening of the dust collection box 41 and connects to the inside of the mixing box 31 from the feed inlet. The ion fan 32 is fixedly installed on one side inside the mixing box 31, with the output port of the ion fan 32 facing the feed inlet of the mixing box 31. The spraying assembly 33 and the stirring assembly 34 are respectively arranged inside the mixing box 31. During implementation, the dust-treated material slides into the mixing box 31 along the inclined filter plate 42. During this process, the dedicated ion fan 32 continuously blows positive and negative ion streams onto the material, effectively neutralizing the net positive charge carried by the material due to friction and electrostatic adsorption in the previous dust removal stage. This not only eliminates the safety hazards that may be caused by static electricity accumulation, but also prevents charged materials from adhering to the box wall or clumping due to adsorption, thereby ensuring uniform mixing with the adhesive and improving mixing efficiency and product texture uniformity.
[0024] The spraying assembly 33 includes a water tank 331, a water pump 332, and a spray pipe 333. The water tank 331 is fixedly mounted on the support frame 1, and the water pump 332 is mounted on the water tank 331, with its two ends fixedly connected to one side of the water tank 331 and one end of the spray pipe 333, respectively. During implementation, the required adhesive or water is added to the water tank 331. After starting the water pump 332, the liquid medium is pumped from the water tank 331 and sprayed evenly in an atomized form onto the materials in the mixing tank 31 through the spray pipe 333. This design achieves a quantitative and uniform supply of adhesive, significantly improving the mixing quality and efficiency of the materials.
[0025] The mixing assembly 34 includes a second motor 341 and a spiral roller 342. The second motor 341 is fixedly installed on the inner wall of the mixing chamber 31 and located below the filter plate 42. One end of the spiral roller 342 is fixedly connected to the output end of the second motor 341. A conveying pipe is fixedly installed on the side of the mixing chamber 31 away from the second motor 341, with one end connected to the inside of the mixing chamber 31. The end of the spiral roller 342 near the conveying pipe is connected to the inside of the conveying pipe. In operation, the second motor 341 is started to drive the spiral roller 342 to rotate. The spiral roller 342 stirs the material in the mixing chamber 31 to ensure that it is fully mixed with the adhesive; at the same time, the part extending into the conveying pipe continuously and stably pushes the uniformly mixed material to the next process.
[0026] The extrusion mechanism 5 includes a compression chamber 51, a conveyor belt 52, a cylinder 53, and a die-casting mold 54. The compression chamber 51 is fixedly mounted on the support frame 1. The end of the conveyor pipe away from the mixing chamber 31 is connected to the inside of the compression chamber 51. The conveyor belt 52 is located inside the compression chamber 51 and below the conveyor pipe. The cylinder 53 is fixedly mounted on the top surface inside the compression chamber 51, and the output end of the cylinder 53 is fixedly connected to the top surface of the die-casting mold 54, which is located directly above the conveyor belt 52. In operation, the mixed material is fed onto the conveyor belt 52 inside the compression chamber 51 via the conveyor pipe. Then, the cylinder 53 is activated, driving the forming mold below it to press down and compress and shape the material on the conveyor belt 52. After pressing and forming, the mold rises, and the finished product is automatically conveyed by the conveyor belt 52 to the subsequent drying process.
[0027] The drying mechanism 6 includes a discharge box 61 and heating lamps 62. The discharge box 61 is fixedly installed on the top surface of the support frame 1. A feed inlet is located on the side of the discharge box 61 near the compression box 51. A conveyor belt 52 connects to the discharge box 61. A door is hinged to one side of the discharge box 61. The heating lamps 62 are strip-shaped and installed on the inner wall of the discharge box 61. During operation, the pressed biomass fuel blocks are continuously fed into the discharge box 61 by the conveyor belt 52. The strip-shaped heating lamps 62 installed on the inner wall of the box are then activated to uniformly and continuously dry the fuel blocks. This process effectively removes moisture, solidifies and shapes the product, and achieves the preset moisture content standard, thus completing the entire processing flow.
[0028] A method of using a biomass fuel processing impurity removal device, applicable to any one of the above-mentioned technical solutions, includes the following steps: S1: Material enters the crushing box 21 from the feed port; S2: The second motor 341 is started to drive the cutting roller 23 to crush the material; S3: The crushed material is conveyed through the conveying pipe 24 to the filter plate 42 in the dust collection box 41, where it carries a positive charge; S4: The crushed material falls onto the filter plate 42, generating upward-floating dust. Large dust particles fall directly into the dust collection box 45. By starting the fan 43, the dust is blown towards the electrode plate 44, where the negative charge on the electrode plate 44 adsorbs the positively charged dust; S5: The filtered and crushed material enters the mixing box 31 along the filter plate 42. S6: The ion fan 32 is activated to neutralize the positive charge carried by the crushed material; S7: The neutralized crushed material falls to the bottom of the mixing box 31, and the water pump 332 is activated to spray water from the water tank 331 onto the neutralized crushed material through the water spray pipe 333; S8: The second motor 341 is activated to drive the spiral roller 342 to stir the crushed material and transport it to the conveying pipe; S9: The mixed material is transported from the conveying pipe to the conveyor belt 52 in the compression box 51 through the spiral roller 342; S10: The cylinder 53 is activated to push the die-casting mold 54 to shape the material; S11: The shaped material is transported to the discharge box 61 through the conveyor belt 52 and dried through the heating lamp tube 62. By making the filter plate 42 positively charged and the electrode plate 44 negatively charged, and with the guidance of the fan 43, dust of different particle sizes generated during the crushing process can be efficiently separated and adsorbed, removing impurities and significantly improving the purity and combustion efficiency of the final biomass fuel. By setting up the ion fan 32, the residual charge of the material is neutralized before it enters the mixing process, eliminating the safety hazards that may be caused by static electricity accumulation, and more effectively preventing the material from agglomerating or adhering to the box wall due to static adsorption, thereby ensuring the uniformity and stability of the subsequent mixing and extrusion processes and improving the consistency of the product texture. The integrated mixing mechanism 3 of "spraying-stirring-conveying" uses the spiral roller 342 driven by the second motor 341 to fully shear and stir the material, and continuously and stably convey it to the extrusion mechanism 5 for mixing and conveying, ensuring the uniform mixing of the material and the binder, avoiding secondary handling of the material, and improving the overall production efficiency. From material crushing to finished product drying, the entire device uses the conveyor belt 52 to allow the pressed fuel to immediately enter the drying stage, thereby achieving a leap in overall work efficiency.
[0029] Working principle: During implementation, dust-laden material enters the dust collection box 41 via the conveyor pipe 24 and falls onto the positively charged filter plate 42. The dust particles agitated by the falling material repel each other due to their positive charge, with larger particles falling directly into the bottom dust collection box 45 under gravity. The remaining fine dust particles flow to the dust inlet trough under the guidance of the fan 43 and are firmly adsorbed by the negatively charged electrode plate 44, effectively preventing dust from entering subsequent processes. For cleaning, simply open the box door to remove the dust collection box 45 and remove large dust particles; loosen the top screws to remove the electrode plate 44 and clean the fine dust adsorbed on its surface, making maintenance convenient and efficient.
