Description

Technical Field

[0001] This invention relates to the technical field of special equipment for the harmless treatment of solid waste, and in particular to a harmless treatment system for solid waste. Background Technology

[0002] The applicant previously disclosed a smelting process for magnesium-containing hazardous waste / solid waste in a patent (publication number CN109182733B), comprising the following steps: S1 Pretreatment: The magnesium-containing hazardous waste / solid waste is crushed using a crusher, and iron powder, lime, and slag are added sequentially during the crushing process to obtain a solid waste mixture; S2 Brick making: 16-25% by weight of water is added to the solid waste mixture obtained in S1, and then bricks are formed using a brick-making machine; S3 Adding 2-8% by weight of limestone, 1-4% by weight of iron(III) oxide, 1-3% by weight of serpentine, 1-2% by weight of industrial alumina, and 1-2% by weight of sodium silicate to the finished bricks obtained in S2 to obtain a smelting material; S4 Smelting: 5-20% by weight of coke is added to the smelting furnace, and then the smelting material obtained in S3 is added to the smelting furnace, and the smelting furnace is turned on. The beneficial effects of this invention are: it can maintain normal smelting temperature, thus controlling fuel costs; after brick making, the finished bricks are only naturally cured before smelting. During the natural curing process, iron reacts fully with air to generate more valence iron, which can improve the copper extraction rate. In step S1, a crusher is needed to crush the solid waste (magnesium-containing hazardous waste / solid waste). During the crushing process, multiple ingredients (iron powder, lime, and slag) need to be added. Since the existing crusher can only add one ingredient at a time, they need to be added sequentially. The subsequent crusher running time also needs to be increased accordingly to ensure uniform material mixing, thus increasing the overall time consumption and reducing efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a solid waste harmless treatment system that solves the problem of reduced overall efficiency caused by the need to add ingredients sequentially in existing technologies.

[0004] According to an embodiment, a solid waste harmless treatment system is provided, which includes a crusher. The crusher includes a casing, a feed hopper fixedly connected to and communicating with the casing, a horizontally arranged feeding pipe fixedly arranged inside the casing, a stirring assembly inside the feeding pipe, a plurality of feeding hoppers arranged along the length of the feeding pipe fixedly connected to the casing, a guide shell fixedly connected to the casing and communicating with the feeding pipe, a circulating fan being provided between the guide shell and the casing, the circulating fan having a first air inlet pipe and a first air outlet pipe, the first air inlet pipe communicating with the guide shell, and a tee pipe fixedly connected to the first air outlet pipe, the tee pipe having a first pipe section communicating with the first air outlet pipe and a second pipe section and a third pipe section communicating with the casing and the feeding pipe respectively. Similar to existing technologies, the feeding hopper in this solution guides the material into the machine casing. However, unlike existing technologies, this solution uses multiple batching hoppers to separately introduce various ingredients into the batching pipe. The mixing components can mix the ingredients, and during the mixing process, the circulating fan continuously draws the ingredients into the guide shell and then into the machine casing. This makes the batching and feeding process more convenient and efficient, shortening the overall time compared to existing technologies and thus improving overall efficiency. It also solves the problem that the need to add ingredients sequentially in existing technologies leads to a decrease in overall efficiency.

[0005] Furthermore, a connecting hole is provided at the end of the feeding pipe away from the material guide shell, and the third pipe section is connected to the connecting hole.

[0006] Furthermore, the mixing assembly includes a first mounting shaft that rotates inside the feeding tube and a spiral blade that is fixedly surrounding the first mounting shaft. The spiral blade is close to the inner bottom surface of the feeding tube and far from the inner top surface. A first driver that drives the first mounting shaft to rotate is also fixedly connected to the outside of the housing.

[0007] Furthermore, a first common wall is provided between the material guide shell and the material dispensing pipe, one end of the first mounting shaft is rotatably connected to the first common wall, and the bottom of the first common wall is provided with a first connecting port that connects the material guide shell and the material dispensing pipe.

[0008] Furthermore, a second common wall is provided between the feed guide shell and the machine housing, and a second connecting port connecting the feed guide shell and the machine housing is provided on the second common wall.

[0009] Furthermore, the circulating fan is installed on the top surface of the guide shell, and the first air inlet pipe is connected to a vertical pipe that runs through the guide shell. The vertical pipe is provided with multiple air holes that connect it to the guide shell, and the vertical pipe is also connected with plugs located below the air holes.

[0010] Furthermore, the vertical pipe is also equipped with a guide port located below the air hole and opposite the second connecting port, and the guide port is either blocked or opened by a plug.

[0011] Furthermore, the batching hopper is connected to the batching pipe via a connecting pipe, and a first valve is installed on the connecting pipe.

[0012] Furthermore, a second mounting shaft is vertically rotatably installed at the bottom of the casing, and a crushing blade located inside the casing is fixedly connected to the second mounting shaft. A second drive is also installed outside the casing to drive the second mounting shaft to rotate.

[0013] Furthermore, the bottom of the housing is provided with multiple openings that surround the second mounting shaft and connect the inside and outside of the housing, and the housing is also provided with multiple gates for opening and closing each opening.

[0014] Compared with the prior art, the present invention has the following beneficial effects: By setting multiple feeding hoppers on the crusher casing, various ingredients are simultaneously introduced into the feeding pipe, where they are mixed. During the mixing process, a circulating fan runs to continuously draw the ingredients into the guide shell and then into the casing. This makes the feeding process more convenient and efficient, shortening the overall time compared to existing technologies and thus improving overall efficiency. It also solves the problem that the need to add ingredients sequentially in existing technologies leads to a decrease in overall efficiency. Attached Figure Description

[0016] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1-3As shown, this embodiment provides a solid waste harmless treatment system, which includes a crusher. The crusher includes a casing 1, and a feed hopper 2 is fixedly connected to and communicates with the casing 1. The feed hopper 2 is used to introduce materials (solid waste, such as magnesium-containing hazardous waste / solid waste in the background art) into the casing 1. A horizontally arranged feeding pipe 3 is fixedly installed inside the casing 1, and a stirring assembly is installed inside the feeding pipe 3. Multiple feeding hoppers 4 are also fixedly connected to the casing 1 along the length of the feeding pipe 3. These feeding hoppers 4 are respectively connected to the feeding pipe 3 through a connecting pipe 5, and a first valve is installed on the connecting pipe 5. Door 6, the first valve 6 can be a solenoid valve, and multiple batching hoppers 4 are used to load batching materials (such as iron powder, lime and slag in the background art). The specific number can be determined according to the type of batching materials, or more can be set, and some can be selected for use. A guide shell 7 is also fixedly connected to the housing 1, which connects to the batching pipe 3. A circulating fan 8 is also provided between the guide shell 7 and the housing 1. The circulating fan 8 has a first air inlet pipe and a first air outlet pipe. The first air inlet pipe of the circulating fan 8 is connected to the guide shell 7, and a T-shaped pipe is fixedly connected to the first air outlet pipe. The T-shaped pipe has a connection to the first air outlet pipe. The first pipe section 9, and the second pipe section 10 and the third pipe section 11, which are respectively connected to the casing 1 and the feeding pipe 3, are equipped with a second valve 12 and a third valve 13, which can also be solenoid valves. Furthermore, unlike existing technologies, this solution uses multiple feeding hoppers 4 to introduce various ingredients into the feeding pipe 3. A mixing assembly can then be used to mix the ingredients. During the mixing process, the circulating fan 8 continuously draws the ingredients into the guide shell 7 and then into the casing 1. This makes the feeding process more convenient and efficient compared to existing methods. There is a technology that can shorten the overall time consumption, thereby improving the overall efficiency and solving the problem that the overall efficiency is reduced due to the need to add ingredients sequentially in the existing technology. More specifically, during operation, the first valve 6 is opened and the ingredients enter the batching pipe 3. The circulating fan 8 and the mixing component are running. At this time, the second valve 12 and the third valve 13 are opened. During the mixing process, the circulating fan 8 draws the ingredients into the guide shell 7. The ingredients are heavy and fall into the machine casing 1 through the guide shell 7. After all the ingredients have fallen into the machine casing 1, the second valve 12, the third valve 13 and the circulating fan 8 are closed.

[0018] In further proposals, such as Figure 1-3As shown, a connecting hole 14 is provided at the end of the dispensing pipe 3 away from the guide shell 7. The third pipe section 11 is connected to the connecting hole 14. The dispensing assembly includes a first mounting shaft 15 that rotates inside the dispensing pipe 3 and a spiral blade 16 fixedly surrounding the first mounting shaft 15. The spiral blade 16 is close to the inner bottom surface of the dispensing pipe 3 and away from the inner top surface. A first driver that drives the first mounting shaft 15 to rotate is also fixedly connected to the outside of the housing 1. That is, the dispensing pipe 3 has a space above the spiral blade 16. Each connecting pipe 5 is also connected to this space. Since the material is connected to the space, the ingredients can fall more smoothly into the dispensing pipe 3 after passing through the connecting pipe 5. The first drive motor 17 is similar to that in the prior art and may include the first drive motor 17 and the first reducer 18 connected to it. The first mounting shaft 15 extends rotatably outside the housing 1 and is connected to the output end of the first reducer 18. In this way, the operation of the first drive motor 17 can drive the first mounting shaft 15 to rotate. More specifically, the end of the dispensing pipe 3 away from the guide hopper has a long section where the dispensing hopper 4 is not installed (i.e., the dispensing hopper 4 is not installed). The hopper 4 is closer to the feed guide shell 7. At the start of operation, the spiral blades 16 push the ingredients towards the end without the hopper 4, and then back again, repeating this process multiple times for better mixing. Simultaneously, the circulating fan 8 operates throughout the entire process, allowing a small portion of the ingredients to enter the feed guide shell 7 first and then fall into the machine casing 1. After a period of operation, the first drive motor 17 continues to operate, causing the spiral blades 16 to push all the ingredients towards the feed guide shell 7. Combined with the circulating fan 8, this ultimately efficiently and thoroughly transfers the ingredients to the machine casing 1. Inside shell 1, the feeding process is completed. More specifically, this solution includes a second pipe section 10 and a third pipe section 11, which connect the circulating fan 8 to the shell 1, the feeding pipe 3, and the guide shell 7, ensuring that the feeding material can fall normally into the shell 1. In particular, the connecting hole 14 is located above the spiral blade 16, which can prevent accidental blockage of the feeding material. Even if some of the feeding material comes into contact with the connecting hole 14, the airflow blown into the feeding pipe 3 by the circulating fan 8 can quickly blow it away, without affecting the normal operation of the system.

[0019] like Figure 1 , 3As shown, in a further embodiment, a first common wall 19 is provided between the guide shell 7 and the dispensing pipe 3. One end of the first mounting shaft 15 is rotatably connected to the first common wall 19, and the bottom of the first common wall 19 is provided with a first connecting port 20 connecting the guide shell 7 and the dispensing pipe 3. The first connecting port 20 serves to connect the dispensing pipe 3 and the guide shell 7, and it is located below the first mounting shaft 15 and can be flush with the inner bottom surface of the dispensing pipe 3, thus preventing material from stagnating at the connection point. More specifically, the upper end of the first common wall 19 can also have an arc-shaped transition with the inner top surface of the dispensing pipe 3, and the higher side connects with the inner top surface of the dispensing pipe 3, thus allowing the circulating fan 8 to operate. The airflow passes through an arc-shaped transition and slopes downwards, which helps the ingredients to enter the first connecting port 20 more smoothly, and then into the guide shell 7. Furthermore, a second common wall 21 is provided between the guide shell 7 and the machine housing 1. A second connecting port 23 is provided on the second common wall 21 to connect the guide shell 7 and the machine housing 1. That is, the second connecting port 23 is located below the first connecting port 20. At the same time, the guide shell 7 has an inclined bottom plate 22 that connects to the lower edge of the second connecting port 23. The higher end of the inclined bottom plate 22 is away from the second connecting port 23. In this way, after the ingredients enter the guide shell 7, they fall downwards and can also be guided by the inclined bottom plate 22 into the second connecting port 23, and then fall into the machine housing 1.

[0020] In further proposals, such as Figure 1 , 3As shown in Figure 4, the circulating fan 8 is installed on the top surface of the material guide shell 7, and the first air inlet pipe is connected to a vertical pipe 24 that runs vertically through the material guide shell 7. The vertical pipe 24 has multiple air holes 25 connecting it to the material guide shell 7. These air holes 25 can be located on the side near the first connecting port 20. A plug 26 is also inserted into the vertical pipe 24 below the air holes 25. The plug 26 is used to seal the lower end of the vertical pipe 24. When the circulating fan 8 runs, a negative pressure is generated inside the vertical pipe 24, and airflow is drawn in through the air holes 25, causing a negative pressure inside the material guide shell 7. Simultaneously, the airflow also enters the end of the dispensing pipe 3 away from the first connecting port 20 and flows towards the first... The connecting port 20 moves, eventually allowing the ingredients to pass through the first connecting port 20 into the guide shell 7, and then fall downwards through the second connecting port 23 into the machine housing 1. In a more specific embodiment, the vertical pipe 24 is fixedly inserted through the higher end of the inclined base plate 22 into the guide shell 7. This ensures that the air vent 25 on the vertical pipe 24 is a considerable distance from the first connecting port 20, preventing the ingredients from being directly sucked into the vertical pipe 24. However, some ingredients may still enter the vertical pipe 24. A guide port 27 is also provided on the vertical pipe 24, located below the air vent 25 and opposite the second connecting port 23. The plug 26 blocks or opens the guide port 27. More specifically... The top surface of the plunger 26 can also be inclined, and its lower part can connect with the lower edge of the guide port 27. When the circulating fan 8 is running, the lower side of the top surface of the plunger 26 can connect with the lower edge of the lowest air hole 25, so that some of the material entering the vertical pipe 24 can slide down and return to the guide shell 7. Furthermore, when all the material in the dispensing pipe 3 has been discharged, the plunger 26 can be moved downward so that the lower side of the top surface of the plunger 26 connects with the lower edge of the guide port 27, so that any material that accidentally enters the vertical pipe 24 can leave through the guide port 27. Furthermore, the circulating fan 8 can also be reversed or the flow can be reversed. An additional blower 28 supplies airflow to the upper end of the vertical pipe 24 to assist the material in leaving the guide shell 7 and entering the housing 1 (or prevents the plunger 26 from moving downwards). More specifically, the blower 28 has a second air inlet pipe 29 and a second air outlet pipe 30. The second air inlet pipe 29 is connected to the inside of the housing 1, and the second air outlet pipe 30 is connected to the upper end of the vertical pipe 24. Furthermore, the plunger 26 has a portion located below and outside the vertical pipe 24, and the plunger 26 and the vertical pipe 24 can be fixed together relative to each other by a positioning rod 31. At this time, the lower side of the top surface of the plunger 26 is exactly connected to the lower edge of the air hole 25 located at the lowest point.

[0021] like Figure 1As shown, the crusher in this design also has a second mounting shaft 32 inside the casing 1. Specifically, the second mounting shaft 32 is vertically rotatably inserted through the bottom of the casing 1. Crushing blades 33 located inside the casing 1 are fixedly connected to the second mounting shaft 32. A second drive unit is also provided outside the casing 1 to drive the second mounting shaft 32 to rotate. Similar to the first drive unit, the second drive unit may include a second drive motor 34 and a second reducer 35 connected to the second drive motor 34. The lower end of the second mounting shaft 32 is connected to the output end of the second reducer 35. Thus, the operation of the second drive motor 34 drives the second mounting shaft 32 to rotate, thereby enabling the crushing blades 33 to crush and mix the material. Furthermore, multiple [unclear - possibly a series of unclear characters] are also provided at the bottom of the casing 1, surrounding the second mounting shaft 32 and connecting the inside and outside of the casing 1. The casing 1 is also equipped with multiple gates 37 for opening and closing each opening 36. These gates 37 are closed during crusher operation and open after operation so that material can be discharged downward through the opening 36. Furthermore, an annular guide box 38 is fixedly connected to the bottom of the casing 1, located below and communicating with the opening 36. The guide box 38 is also fixedly connected to a discharge hopper 39. Material first enters the guide box 38 and then is discharged outward through the discharge hopper 39. The guide box 38 can also be inclined, and the discharge hopper 39 is located at the lowest point. More specifically, the gate 37 has an end located outside the casing 1 and is fixedly connected to a connecting plate 40. The connecting plate 40 can be detachably connected to the casing 1 by bolts or other fasteners, so that the gate 37 can be easily installed and removed.
