[0036] The multi-source organic solid waste graded pyrolysis conversion device is a device used to treat organic solid waste from various sources. It converts waste into useful products or energy through the process of pyrolysis and conversion. Before the waste is pyrolyzed, the waste must be pretreated first. The pretreatment mainly includes the separation of metal impurities in the waste, the crushing of the waste, the screening of the waste particle size and the drying of the waste.

[0037] Among them, metal impurities in the waste may cause damage, wear or blockage to the internal components of the pyrolysis equipment. Removing metal impurities can reduce the frequency of equipment maintenance and replacement, and improve the service life and operating efficiency of the equipment. Metal impurities may interfere with the reaction process during the pyrolysis process, affecting product quality and conversion efficiency. Removing metal impurities helps ensure the stability and efficiency of the pyrolysis reaction. At the same time, metal is a valuable resource that can be recycled and reused.

[0038] In this solution, the user can drop the waste from the top of the separation box 4 so that the waste enters the inner cavity of the separation box 4, and the waste will fall on multiple buffer plates 10. During the falling process, the waste continuously collides with multiple buffer plates 10, which can disperse the waste and reduce the degree of mutual adhesion of the waste. At the same time, the metal impurities mixed in the waste can be separated as much as possible.

[0039] See also Figure 4 A hot air blower 11 is installed on the bracket 3 , and a ventilation pipe 12 is fixedly connected to the output end of the hot air blower 11 . Multiple pipes on the ventilation pipe 12 all extend to the inner cavity of the separation box 4 .

[0040] When the waste passes through the inner cavity of the separation box 4, the user starts the hot air blower 11, and the hot air blower 11 sends hot air into the interior of the separation box 4 through the ventilation pipe 12, so that the internal temperature of the separation box 4 increases, thereby preheating the waste in the separation box 4, which is beneficial to the subsequent drying of the waste. The setting of multiple buffer plates 10 can slow down the speed at which the waste falls, so that the waste can be fully heated.

[0041] See also Figure 2 and 5 The driving component 14 includes a bidirectional screw rod 142 and a pair of matching screw sleeves 143. The bidirectional screw rod 142 is rotatably connected to the bracket 3. The pair of screw sleeves 143 are respectively fixedly connected to a pair of retaining plates 5. The driving component 14 also includes a servo motor 141. The servo motor 141 is installed on the bracket 3, and the output end of the servo motor 141 is fixedly connected to the bidirectional screw rod 142.

[0042] A pair of intercepting plates 5 abut against each other and surround the lower side of the separation box 4 in a surrounding manner. The user can start the electromagnet 6 to form a magnetic field between the pair of intercepting plates 5, so that when the waste falls from the lower end of the separation box 4, the waste will pass between the pair of intercepting plates 5, and the metal impurities in the waste will be adsorbed by the intercepting plates 5, while the remaining waste will fall into the crusher 7 for crushing. After the metal impurities are intercepted, the user starts the servo motor 141 to drive the bidirectional screw rod 142 to rotate. The rotation of the bidirectional screw rod 142 can drive the pair of screw sleeves 143 to move, thereby forcing the pair of intercepting plates 5 to move away from each other.

[0043] See also Figure 1 Both ends of the pulverizer 7 are fixedly connected with guide plates 13, and both sides of the conveyor belt 1 are provided with collecting boxes 8, which are located directly below the guide plates 13.

[0044] After moving away from each other, the pair of intercepting plates 5 respectively come to the upper side of a pair of guide plates 13. At this time, the user turns off the electromagnet 6, the intercepting plate 5 loses its magnetic field, and the metal impurities adsorbed on its inner end will automatically fall off and fall onto the guide plate 13, and then slide into the collection box 8 along the guide plate 13, thereby realizing the centralized collection of the metal impurities.

[0045] See also Figure 2 and 6 The sieve plate 9 is arranged at an angle, and the end of the sieve plate 9 away from the bracket 3 is fixedly connected to the shell 15, the inner cavity of the shell 15 is equipped with a matching auger 16, the top of the shell 15 extends to the upper side of the crusher 7, and the end of the shell 15 close to the crusher 7 is fixedly connected to a return plate 17, and one end of the return plate 17 extends to just above the crusher 7.

[0046] By crushing the waste by the crusher 7, the waste can be broken down into smaller particles or fragments, thereby increasing its surface area. By increasing the surface area of ​​the waste, the contact area between the waste and other substances can be increased, promoting the reaction rate and efficiency. At the same time, the crushed waste particles are easier to mix and evenly distribute. The uniform mixing can ensure the uniform distribution of various components in the waste, making the subsequent processing process more stable and controllable.

[0047] The waste crushed by the crusher 7 falls onto the sieve plate 9 and slides down the sieve plate 9. During the sliding process, smaller particles of waste are screened by the sieve plate 9 and fall onto the conveyor belt 1, while larger waste particles that cannot pass through the sieve plate 9 slide down the sieve plate 9 into the outer casing 15. Excessively large particles may cause equipment blockage, excessive wear or insufficient treatment. Through the particle screening of the sieve plate 9, excessively large particles can be removed, ensuring the smooth progress of the subsequent treatment process and obtaining better treatment effects and product quality.

[0048] The particles that fall into the housing 15 are conveyed by the auger 16 to the upper side of the inner cavity of the housing 15, and finally slide back into the pulverizer 7 through the return plate 17, and are pulverized again by the pulverizer 7 until the qualified particle size is reached.

[0049] The waste that falls onto the conveyor belt 1 will enter the drying box 2 along the conveyor belt 1 for drying. This is because the waste may contain high water content or humidity, which may affect the efficiency of the pyrolysis process and the quality of the product. Through drying treatment, its moisture content can be reduced and the pyrolysis effect can be improved. Finally, the dried waste will enter the pyrolysis device through the conveyor belt 1 for pyrolysis conversion.

[0050] Working principle:

[0051] In this solution, the user first drops the waste from the top of the separation box 4 so that the waste enters the inner cavity of the separation box 4. The waste will fall on multiple buffer plates 10. During the falling process, the waste constantly collides with the multiple buffer plates 10, so that the metal impurities mixed in the waste are separated as much as possible. When the waste passes through the inner cavity of the separation box 4, the user starts the hot air blower 11, and the hot air blower 11 sends hot air into the interior of the separation box 4 through the ventilation pipe 12, so that the internal temperature of the separation box 4 increases, thereby preheating the waste in the separation box 4. Then the user starts the electromagnet 6 to form a magnetic field between a pair of intercepting plates 5. When the waste falls from the lower end of the separation box 4, the waste will pass between the pair of intercepting plates 5. The metal impurities in the waste will be absorbed by the intercepting plates 5, and the remaining waste will fall into the crusher 7 for crushing. After the metal impurities are intercepted, the user starts the servo motor 141 to drive the bidirectional screw rod 142 to rotate, and the rotation of the bidirectional screw rod 142 drives the pair of screw sleeves 143 to move, thereby forcing a pair of The interception plates 5 move away from each other, and the pair of interception plates 5 move away from each other to the upper side of the pair of guide plates 13. At this time, the user turns off the electromagnet 6, the interception plate 5 loses its magnetic field, and the metal impurities adsorbed on its inner end will automatically fall off and fall onto the guide plate 13, and then slide into the collection box 8 along the guide plate 13 to achieve centralized collection of metal impurities. The waste crushed by the crusher 7 falls onto the sieve plate 9 and slides down along the sieve plate 9. During the sliding process, smaller particles of waste are screened by the sieve plate 9 and fall to the conveyor. The waste particles that fall onto the conveyor belt 1 will enter the drying box 2 for drying along the conveyor belt 1, and the dried waste will enter the pyrolysis device through the conveyor belt 1 for pyrolysis conversion.

[0052] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
