After the corresponding waste is treated with different processes, different renewable resources will be produced, and then the existing processes will be used to treat the different renewable resources separately. When treating domestic waste or construction waste, it is usually necessary to use a processing device to crush the raw material blocks. The existing processing device usually includes a crusher body, a crushing barrel, a feed port opened at the top of the crushing barrel, a discharge port opened at the bottom of the crushing barrel, and a crushing mechanism. When the raw material blocks need to be crushed, the raw material blocks are added to the crushing barrel from the feed port, and the raw material blocks are crushed by the crushing mechanism, and the crushed small-size raw material blocks are discharged from the discharge port.

[0003] A Chinese patent application document with publication number CN114643116A discloses a crushing device for mud processing, comprising a box body, a feeding port is arranged on the top of the box body, and a crushing chamber is arranged in the box body, a shredding assembly is arranged in the crushing chamber, the shredding assembly comprises a shredding spindle, a knife roller assembly arranged on the shredding spindle, the knife roller assembly comprises a first shredding tool and a second shredding tool arranged on the shredding spindle at intervals, the teeth on the first shredding tool and the second shredding tool are staggered, and a driving device connected to the shredding spindle is arranged on one side of the box body; when working, sludge and slag are fed into the feeding port of the box body through conveying equipment such as a belt conveyor and a loader, the shredding spindle is driven to rotate at a high speed through a pulley, and then the first shredding tool and the second shredding tool are driven to rotate at a high speed, and during the high-speed rotation of the first shredding tool and the second shredding tool, the first shredding tool and the second shredding tool quickly shred the sludge and slag, cut the material into small particles, and discharge it from the discharge port.

[0004] In the above technology, the raw material block is shredded by the first shredding tool and the second shredding tool. When the mass of the crushed soil is large, a large number of particles will still exist during the crushing by shearing, and the crushing effect of the raw material block is poor.

At this time, the crushing teeth 1 and the crushing teeth 2 can gradually scrape the raw material block at the same time, thereby realizing the crushing operation of the raw material block.

The brick blanks are then transported and stacked for firing, and finally the sintered bricks are stacked and stored to complete the treatment of solid waste.

[0021] Beneficial effect: The rotation of the roller group can drive the rotation of the bottom crushing assembly. When the bottom crushing assembly rotates, it drives the crushing tooth 1 to rotate. At this time, the crushing tooth 1 and the crushing tooth 2 can gradually scrape the raw material blocks at the same time, thereby realizing the crushing operation of the raw material blocks. Compared with the shear crushing method, it can reduce the phenomenon of a large number of particles existing during crushing, thereby improving the crushing effect of the raw material blocks.

The guide surface 213 is inclined along the rotation direction of the rotating roller 211 away from the central axis of the rotating roller 211, and one end of the guide surface 213 extends into the mounting groove.

[0040] The implementation principle of the solid waste treatment device of the present invention is as follows: when the raw material blocks need to be crushed, the raw material blocks are first conveyed to the screw conveying device 8, and then the raw material blocks are conveyed to the feed port 12 by the screw conveying device 8, and then the raw material blocks fall into the crushing cylinder 11, and at this time, the driving member 9 is started to drive the rotating roller 211 to rotate, drive the scraper frame 212 to rotate, and drive the bottom crushing assembly 22 to rotate. While the bottom crushing assembly 22 pushes the raw material blocks to rotate toward the top crushing assembly 23, the crushing teeth 1 222 crush the bottom of the raw material blocks, and the crushing teeth 232 crush the top of the raw material blocks; During the rotation of the crushing tooth 232 along the central axis of the rotating roller 211, the bracket 121 drives the push rod 31 to rotate. When the push rod 31 passes through the adjustment groove 111, the bracket 121 drives the crushing tooth 122 to vibrate slightly along the central axis of the rotating roller 211 through the adjustment groove 111 and the elastic member 32, so as to further crush the raw material block. After the raw material block is crushed, the debris is filtered by the filter plate 7 and discharged through the discharge port 13, thereby completing the crushing operation of the raw material block. When the moisture content of the raw material block is relatively high locally and the raw material sticks to the inner wall of the crushing drum 11, the driver is started to drive the scraper frame 212 to slide along the radial direction of the rotating roller 211, and the scraper frame 212 abuts against the inner wall of the crushing drum 11 (its state is as shown in FIG. Figure 6 As shown), at this time, the bracket 1 221 and the crushing tooth 1 222 are retracted into the installation groove, and the telescopic rod 1 4 is compressed, the bracket 231 and the crushing tooth 232 are retracted into the sliding groove 112, and then the driving member 9 is started to drive the rotating roller 211 to rotate, and the scraping frame 212 is driven to rotate, and the scraping frame 212 scrapes the raw materials on the inner wall of the crushing cylinder 11, and the scraped raw materials can slide into the installation groove along the guide surface 213 to realize the collection of the raw materials. When the scraping frame 212 is retracted away from the inner wall of the crushing cylinder 11, the bracket 1 221 and the crushing tooth 1 222 pop out from the installation groove and push the raw materials out to realize the cleaning operation of the inner wall of the crushing cylinder 11.

[0041] Reference Figure 1-Figure 7 The present invention also provides a solid waste treatment method, which comprises the following steps: Solid waste treatment: Solid waste includes municipal sludge, river sludge, construction waste and domestic waste.

The raw material blocks enter the crushing tube 11 through the feed port 12. At this time, the roller group 21 is driven by the driving member 9 to rotate, and the bottom crushing assembly 22 is driven to push the raw material blocks to rotate toward the top crushing assembly 23. At the same time, the crushing teeth 1 222 and the crushing teeth 232 crush the raw material blocks. Raw material cleaning: Start the driver to drive the scraper frame 212 to slide toward the inner wall of the crushing drum 11, and the outer peripheral surface of the scraper frame 212 abuts against the inner wall of the crushing drum 11. At this time, start the driving member 9 to drive the rotating roller 211 to rotate, and drive the scraper frame 212 to clean the raw materials on the inner wall of the crushing drum 11; Recycling of crushed materials: The crushed debris and fine powder are used as sintering materials, and the sludge recycled fuel and distillation charcoal are used as internal fuel, which are used together as raw fuel for sintered brick making for construction. The materials are then subjected to subsequent crushing, screening, mixing, conveying, aging of the mixture, making of brick blanks, conveying, stacking and firing production and processing. The processed sintered bricks are stacked and stored, completing the treatment of solid waste.
