Description

Technical Field

[0001] This invention relates to the field of waste incineration technology, specifically to a device for processing slag resources from a municipal solid waste incinerator. Background Technology

[0002] A waste incinerator is a device for incinerating and processing waste. Waste burns in the furnace, turning into exhaust gas which enters the secondary combustion chamber. Under forced combustion by the burner, the gas is completely burned, then enters a spray dust collector. After dust removal, it is discharged into the atmosphere through a chimney. A waste incinerator consists of four main systems: a waste pretreatment system, an incineration system, a flue gas biochemical dust removal system, and a gasifier (for auxiliary ignition and incineration). It integrates automatic feeding, screening, drying, incineration, ash removal, dust collection, and automated control.

[0003] When applying for this invention, the applicant, after searching, discovered a Chinese patent that discloses "A Resource Utilization Device for Municipal Solid Waste Incinerator Slag," application number "201721834406.5." This patent mainly adds a flexible solar panel, which makes reasonable use of the vacant resources on the outer surface of the incinerator, improving the energy efficiency and environmental protection of this invention. Because this invention adds a spiral heating wire, this design prevents the slag from easily slagging when cooling outside the furnace, making it difficult to directly use the slag to make concrete bricks. Because this invention adds a rotary motor and stirring blades, this design accelerates the mixing speed of cement, slag, and water, improving the brick-making speed of this invention. Because a sealing ring is provided at the intersection of the mixing box and the rotating shaft, this design increases the sealing performance of this invention. This invention has a simple structure, is easy to operate, and has high brick-making efficiency.

[0004] However, the device still has shortcomings in its use. Due to the different types of waste, metal materials may be mixed in, which will cause waste of resources and incomplete combustion during the incineration process. Secondly, the device cannot screen the slag according to its size, which will cause inconvenience in subsequent use. Summary of the Invention

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example:

[0037] like Figure 1-5 As shown, this embodiment of the invention provides a waste incinerator slag resource processing device, including a processing box 1, an incinerator 2, a sorting box 3, a dispersing mechanism 4, and a vibration mechanism 5. A first conveyor 13 is connected between the processing box 1 and the incinerator 2 to realize the transportation of waste, and a second conveyor 18 is provided between the incinerator 2 and the sorting box 3 to realize the transportation of slag.

[0038] The upper surface of the processing box 1 is provided with two inlets 11 for the input of bagged waste. The dispersing mechanism 4 includes a first motor 41, which is fixedly connected to the outer left side of the processing box 1. The output end of the first motor 41 extends into the interior of the processing box 1 and is fixedly connected to a rotating shaft 42. The inner end of the rotating shaft 42 is fixedly connected to a commutator 43. The commutator 43 contains two meshing bevel gears (not shown in the figure) which serve as a commutator. This is a prior art technology and will not be described in detail here. The bottom end of the commutator 43 is fixedly connected to a rotating rod 44. The outer wall of the rotating rod 44 is fixedly connected to a dispersing disc 45, which increases in size from top to bottom.

[0039] The above structure, driven by the first motor 41, drives the rotating shaft 42 and the rotating rod 44 to rotate, which in turn drives the dispersing disc 45 to rotate, thereby breaking up the garbage and facilitating its sorting and processing.

[0040] The front and rear outer surfaces of the commutator 43 are fixedly connected with bag-piercing needles 12, which are used to pierce the bagged garbage and facilitate the garbage to fall off.

[0041] The processing box 1 is equipped with a conveyor belt 6 that rotates clockwise. The outer surface of the conveyor belt 6 is provided with several magnets to attract metal substances mixed in with the garbage. The left side of the conveyor belt 6 extends to the outside of the processing box 1. A baffle 9 is fixedly connected to the right inner wall of the processing box 1 above the conveyor belt 6 to guide the garbage and prevent it from flying around. A scraper 7 is fixedly connected to the left outer surface of the processing box 1 above the conveyor belt 6. The bottom of the scraper 7 is attached to the outer surface of the conveyor belt 6 to scrape off metal substances. A collection box 8 is provided on the left outer surface of the processing box 1 below the scraper 7 to collect the scraped metal substances. A first feed plate 10 is provided at the bottom of the inner side of the processing box 1 to guide the garbage.

[0042] In the above structure, the garbage falls onto the conveyor belt 6, and the metal substances mixed in the garbage are attracted by the magnet. After being transported by the conveyor belt 6, the garbage is scraped into the collection box 8 by the scraper 7 for collection, thus realizing the recycling and reuse of metal resources.

[0043] A flue pipe 14 is installed through the upper surface of the incinerator 2. A heat recovery pipe 15 is fixedly sleeved on the outer wall of the flue pipe 14. A water inlet pipe 151 is installed through the bottom right side of the heat recovery pipe 15, and a drain pipe 152 is installed through the upper left side of the heat recovery pipe 15.

[0044] In the above structure, the water inlet pipe 151 is used to introduce cold water, which enters the heat recovery pipe 15 to absorb the heat of the hot smoke, and then is discharged from the drain pipe 152, thus realizing heat recovery.

[0045] A filter box 16 is fixedly connected to the outer end of the exhaust pipe 14. The filter box 16 is equipped with a filter screen 161 and an activated carbon adsorption screen 162. An exhaust pipe 17 is installed through the right end of the filter box 16.

[0046] With the above structure, harmful substances in the flue gas will be filtered and adsorbed twice by the filter screen 161 and the activated carbon adsorption screen 162 before being discharged, thus protecting the environment.

[0047] A first screen 19 is slidably connected inside the sorting box 3. A second screen 20 is slidably connected inside the sorting box 3 and below the first screen 19. The mesh count of the second screen 20 is greater than that of the first screen 19. A slider 191 is fixedly connected to the left side of both the first screen 19 and the second screen 20. The slider 191 is slidably connected to the groove 192 opened in the inner wall of the sorting box 3. A spring 193 is fixedly connected to the bottom of both the first screen 19 and the second screen 20.

[0048] In the above structure, the first screen 19 and the second screen 20 reciprocate under the action of the spring 193.

[0049] The vibration mechanism 5 acts between the first screen 19 and the second screen 20. The vibration mechanism 5 includes a connecting frame 51, which is fixedly connected to the inner left side wall of the sorting box 3 and located between the first screen 19 and the second screen 20. A second motor 52 is installed inside the connecting frame 51. A motor shaft 53 is fixedly connected to the output end of the second motor 52. A turntable 54 is fixedly connected to the outer end of the motor shaft 53. A connecting rod 55 is rotatably connected to the outer surface of the turntable 54. A sliding plate 56 is rotatably connected to the upper end of the connecting rod 55. The slide plate 56 is slidably connected to the inner wall of the connecting frame 51. A guide rod 57 is fixedly connected to the middle of the upper surface of the slide plate 56. The outer end of the guide rod 57 slides through to the outside of the connecting frame 51 and is fixedly connected to a top rod 58. A limit groove 59 is opened at the point where the guide rod 57 passes through the connecting frame 51. A second feed plate 21 is provided at the bottom of the sorting box 3 to guide the material. Three discharge ports 22 are connected to the outer surface of the right side of the sorting box 3. Discharge valves are provided inside the discharge ports 22 to discharge the screened slag.

[0050] The above structure, driven by the second motor 52, drives the turntable 54 to rotate. Under the connection of the connecting rod 55, it drives the slide plate 56 and the guide rod 57 to move up and down reciprocally, thereby realizing the up and down reciprocating movement of the top rod 58. This can reciprocate the vibration of the first screen 19 and the second screen 20, thereby achieving rapid screening of slag.

[0051] Working principle: When this municipal solid waste incinerator slag resource processing device is in use, bagged garbage is put into the device through two feed ports 11. After the garbage bag is pierced by the bag-piercing needle 12, the garbage falls onto the dispersing plate 45. The dispersing plate 45 rotates to break up the garbage. The broken garbage falls onto the conveyor belt 6. The metal substances mixed in the garbage are attracted by the magnet. After being conveyed by the conveyor belt 6 and scraped into the collection box 8 by the scraper 7, the metal resources are recycled and reused.

[0052] The remaining waste falls onto the first feed plate 10 and, under the conveying action of the first conveyor 13, enters the incinerator 2 for incineration. The flue gas generated during incineration enters the exhaust pipe 14 upwards and is fed into the water inlet pipe 151 with cold water. The cold water enters the heat recovery pipe 15 to absorb the heat from the hot flue gas and is then discharged from the drain pipe 152, thus realizing heat recovery. Secondly, the harmful substances in the flue gas will be filtered and adsorbed by the filter screen 161 and the activated carbon adsorption screen 162 before being discharged, thus protecting the environment.

[0053] After incineration, the slag enters the sorting box 3 under the action of the second conveyor 18. Under the action of the vibration mechanism 5, the top rod 58 moves up and down reciprocally, which can reciprocate the first screen 19 and the second screen 20 to achieve rapid screening of the slag, and discharge it from the three discharge ports 22 respectively.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
