Description

Technical Field

[0001] This utility model relates to the field of incinerator slag recycling technology, specifically a crushing and screening device for incinerator slag recycling. Background Technology

[0002] Incinerator slag recycling can achieve slag reduction, harmlessness and resource utilization, reduce land occupation and reduce environmental pollution risks. It is widely used in urban waste treatment, industrial waste resource utilization and other fields. Usually, incinerator slag recycling requires the use of crushing and screening devices. When using existing crushing and screening devices, because the shape of slag is close to that of a ball, it is easy to roll. Therefore, the device cannot classify and compress the easily rolling slag to deform it before crushing.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese patent application number: 202321543762.7, application date: June 16, 2023) discloses a crushing device for recycling municipal solid waste incinerator slag, including a crushing box. Inside the crushing box, from top to bottom, are installed an anti-splashing mechanism, a crushing mechanism, and a screening mechanism. A suction mechanism cooperating with the crushing mechanism is symmetrically installed on the top of the outer surface of the crushing box, and a collection mechanism cooperating with the screening mechanism is installed in the middle of the outer surface of the crushing box. Through the suction mechanism and the anti-splashing mechanism, the interference and pollution of the open feed inlet to the workers' working environment during slag crushing can be reduced. Through the screening mechanism and the collection mechanism, the operation of the vibrating motor can drive the screen to vibrate, thereby screening the crushed slag and achieving the distinction between whether the slag has been crushed to the required appropriate particle size, making it highly practical.

[0004] Although existing technologies can reduce the interference and pollution of workers' working environment caused by open feed inlets during slag crushing, the slag in incinerators often contains large particles and dust. Direct entry into the crushing device can easily cause dust to clog the screen, affecting the screening accuracy. Furthermore, the slag after screening usually needs to be graded and recycled according to particle size, but the device does not have a collection and removal structure, making it inconvenient to remove the screened slag.

[0005] Therefore, we proposed a crushing and screening device for incinerator slag recycling that can effectively solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 The present invention provides the following technical solution:

[0027] Example 1: To address the problem that in commercially available crushing devices often contain large particles and dust that directly enter the screen, causing clogging and affecting screening accuracy, this example discloses the following technical details of a crushing and screening device for incinerator slag recycling. (See attached document for reference.) Figure 1 - Appendix Figure 6The system includes a crushing box 1, a support frame 2 fixedly installed on the left side of the crushing box 1, a recycling box 3 fixedly connected to the top of the support frame 2, a sealing cover 4 movably connected to the top of the recycling box 3, a feed hopper 5 fixedly installed on the top of the sealing cover 4, and screening components for vibration on the inner walls of both sides of the recycling box 3, the screening components including a base 6; a servo motor body 11 is provided on the left side of the crushing box 1, a rotating rod 12 is fixedly installed on the output shaft of the servo motor body 11 through a coupling, a first crushing roller 13 is fixedly installed on the outer wall of the rotating rod 12, and a screening plate 17 is movably connected inside the crushing box 1; a vibrator body 7 is provided on the top of the base 6, and a resonance spring 8 is fixedly installed on the top of the vibrator body 7. A vibrating body 9 is fixedly connected to the top, and a screening plate 10 is bolted to the top of the vibrating body 9; a first gear 14 is fixedly connected to the outer wall of the right side of the rotating rod 12, and a second gear 15 is provided behind the first gear 14. A transmission rod is fixedly installed inside the second gear 15, and a second crushing roller 16 is fixedly installed on the outer wall of the transmission rod; the screening plate 10 and the vibrating body 9 are detachably connected, and a perforated mesh is provided inside the screening plate 10; the first gear 14 and the second gear 15 are meshed, and the first gear 14 and the first crushing roller 13 are tightly fitted with the rotating rod 12; the screening plate 17 and the crushing box 1 are detachably connected, and the screening plate 17 is set with a T-shaped structure, and a through groove is opened on the left side of the crushing box 1.

[0028] The incinerator slag to be recycled is manually fed into the recycling box 3 through the feed hopper 5 by the staff. The slag entering the recycling box 3 falls onto the screening plate 10. With the help of the external control board, the vibrator body 7 is started, which drives the resonant spring 8 and the connected vibrating body 9 to vibrate. In turn, the vibrating body 9 drives the bolt-connected screening plate 10 to vibrate, so that the hollow mesh inside the screening plate 10 can efficiently classify the slag by particle size. Small slag powder falls to the bottom of the recycling box 3, while large particles remain on the screening plate 10. The screened slag enters the crushing box 1 through the connecting pipe 23. The servo motor body 11 is started by the external control board, and its output end The drive rod 12 rotates, which in turn drives the first crushing roller 13 and the first gear 14 to rotate. The first gear 14 meshes with the second gear 15, causing the second gear 15 to drive the second crushing roller 16 connected to the transmission rod to rotate. Thus, the first crushing roller 13 and the second crushing roller 16 rotate synchronously in opposite directions to crush the slag. The crushed slag falls onto the screening plate 17, where large particles are retained and small particles pass through. Large particles enter the collection box 22 along the slope through the trough, while small particles fall into the pull-out box 19 for subsequent processing. This achieves preliminary screening and secondary screening of the incinerator slag.

The left side of the installation plate 21 is fixedly connected to a collection box 22. The top of the crushing chamber 1 is fixedly connected to a connecting pipe 23.

[0030] After storing a large amount of slag in the pull-out box 19 and the collection box 22 respectively, the staff manually pulls the pull-out box 19 outward, causing the pull-out box 19 to slide the slide plate 18 outward in the corresponding slide groove until the pull-out box 19 is removed from the crushing box 1. After being removed, the staff can pour out the screened and recycled slag for subsequent use. Then, the staff manually moves the collection box 22 upward, causing the collection box 22 to move the mounting plate 21 upward until it is separated from the corresponding mounting sleeve 20, thereby removing the collection box 22 from the crushing box 1. After being taken out, the staff pours the screened large slag particles into the feed hopper 5 and re-enters the crushing process, realizing the collection and removal of the screened slag.
