In the description of the present invention, "multiple" means two or more, and "several" means one or more, unless otherwise clearly and specifically defined.

[0031] Please also read Figure 1 , Figure 3 , Figure 7 and Figure 8 , the waste incineration fly ash treatment device provided by the present invention is now described. The waste incineration fly ash treatment device includes a bracket 1, a spray assembly, a rotating assembly, a driving assembly 4 and a plurality of receiving units. The bracket 1 is used to be fixed on the ground. The spray assembly is fixedly connected to the bracket 1, and the spray assembly is used to spray the flue gas. The rotating assembly is rotatably connected to the bracket 1 around a vertical axis. The driving assembly 4 is used to drive the rotating assembly to rotate. A plurality of receiving units are evenly distributed around the rotating axis 31 of the rotating assembly, and the receiving unit includes a receiving barrel 51, the opening of the receiving barrel 51 is upward and connected to the rotating assembly, and the rotation of the rotating assembly enables the plurality of receiving barrels 51 to sequentially receive the wastewater formed after the spray assembly sprays the flue gas.

[0032] Compared with the prior art, the waste incineration fly ash treatment device provided by the present invention first allows the first receiving barrel 51 to receive the wastewater formed after the spray component sprays the flue gas. When the wastewater in the first receiving barrel 51 reaches a certain amount, the driving component 4 drives the rotating component to rotate, so that the second receiving barrel 51 receives the wastewater formed after the spray component sprays the flue gas, and a heavy metal chelating agent is added to the first receiving barrel 51, and the suspended matter in the wastewater in the first receiving barrel 51 is precipitated. After the wastewater in the first receiving barrel 51 is precipitated, the supernatant in the first receiving barrel 51 is taken out, and the sludge in the first receiving barrel 51 is treated. In this way, when the sludge in one of the receiving barrels 51 is treated, the second receiving barrel 51 receives the wastewater; and so on, no matter which receiving barrel 51 is treated, there is always another receiving barrel 51 receiving the wastewater, thereby avoiding the problem of having to suspend the discharge of wastewater into the sedimentation tank when cleaning the sludge at the bottom of the sedimentation tank.

[0033] In some embodiments, see Figure 6The bracket 1 has a first fixed plate 11 and a second fixed plate 12 located below the first fixed plate 11. The first fixed plate 11 and the second fixed plate 12 are both arranged horizontally. The rotating assembly includes a rotating shaft 31. The rotating shaft 31 is arranged vertically. The rotating shaft 31 can rotate and penetrate the first fixed plate 11 above. The side wall of the rotating shaft 31 has two outwardly protruding limiting portions 311. The two limiting portions 311 are respectively fitted with the upper surface and the lower surface of the first fixed plate 11; wherein the driving assembly 4 adopts a motor and is fixed on the second fixed plate 12, and the output shaft of the driving assembly 4 is connected to the rotating shaft 31. The output shaft of the driving assembly 4 drives the rotating shaft 31 to rotate, that is, drives the rotating assembly to rotate. The first fixed plate 11 limits the movement of the rotating shaft 31 in the vertical direction, thereby rotating the rotating shaft 31 and the bracket 1 together, thereby realizing the rotation connection between the rotating assembly and the bracket 1.

[0034] In some embodiments, see Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 , the rotating assembly also includes a first connecting plate 32 and a second connecting plate 33, both of which are horizontally arranged and sleeved and fixed outside the rotating shaft 31, the second connecting plate 33 is located below the first connecting plate 32, and the receiving barrel 51 is slidably arranged in the first connecting plate 32 along the vertical direction. The receiving unit also includes a hydraulic cylinder 52, a lifting plate 53, a fixing member 54 and a lifting shaft 55. The cylinder body of the hydraulic cylinder 52 is fixed on the second connecting plate 33, and the piston rod of the hydraulic cylinder 52 can be retracted in the vertical direction and is fixedly connected to the receiving barrel 51. The lifting plate 53 is horizontally arranged and slidably arranged in the receiving barrel 51 along the vertical direction. The fixing member 54 is located above the receiving barrel 51 and is fixedly connected to the rotating shaft 31, and the side wall of the fixing member 54 has a notch 541. The lifting shaft 55 is vertically arranged and fixed on the lifting plate 53. The lifting shaft 55 is inserted into the notch 541. The side wall of the lifting shaft 55 has a lifting portion 551 protruding outward, and the lifting portion 551 is located on the fixing member 54. The connection between the receiving barrel 51 and the rotating assembly is achieved by the sliding cooperation between the receiving barrel 51 and the first connecting plate 32. When the wastewater in the receiving barrel 51 is completely precipitated, the piston rod of the hydraulic cylinder 52 drives the receiving barrel 51 to move downward to a preset position. During this process, the fixing member 54 can limit the lifting shaft 55 and the lifting plate 53 from moving downward through the lifting portion 551, and the supernatant in the receiving barrel 51 will gradually overflow the receiving barrel 51 and flow out of the receiving barrel 51, and the sludge in the receiving barrel 51 will remain on the lifting plate 53. At this time, the lifting plate 53 is relatively close to the barrel mouth of the receiving barrel 51, so as to facilitate the cleaning of the sludge.

[0035] In some embodiments, the above-mentioned characteristic rotating assembly can be used as follows Figure 1 See the structure shown. Figure 1 The rotating assembly also includes a collecting pipe 34, a water suction pipe 10 and a water pump 110. The axis of the collecting pipe 34 is vertically arranged, and the collecting pipe 34 is sleeved outside all the receiving barrels 51 and fixed on the first connecting plate 32. The water suction pipe 10 is fixedly connected to the bracket 1, and one end of the water suction pipe 10 is located in the collecting pipe 34. The water pump 110 is arranged on the water suction pipe 10. The supernatant flowing out of the receiving barrel 51 falls into the collecting pipe 34 on the first connecting plate 32, and the water pump 110 extracts the liquid in the collecting pipe 34 and collects it through the container.

[0036] Furthermore, a filter may be provided on the water suction pipe 10 to further filter the water flowing through the water suction pipe 10 .

[0037] In some embodiments, the above-mentioned characteristic spray assembly can be used as follows Figure 3 and Figure 4 See the structure shown. Figure 3 and Figure 4 The spray assembly includes a spray box 21, an air inlet pipe 22 and multiple groups of purification components 23. The spray box 21 is fixedly connected to the bracket 1. The spray box 21 is a long strip structure and its length direction extends along the first horizontal direction. The bottom wall of the spray box 21 is provided with a liquid outlet 211. The air inlet pipe 22 is located on one side of the spray box 21 along the first horizontal direction. One end of the air inlet pipe 22 is fixedly connected to the spray box 21 and communicates with the inside of the spray box 21. Multiple groups of purification components 23 are located between the liquid outlet 211 and the air inlet pipe 22. The multiple groups of purification components 23 are arranged in sequence along the first horizontal direction. The purification components 23 include a liquid inlet pipe 231 and a spray head 232 arranged at one end of the liquid inlet pipe 231. The spray head 232 penetrates the top wall of the spray box 21 and is fixedly connected to the top wall of the spray box 21. The air inlet pipe 22 is connected to the smoke outlet of the waste incinerator, and the liquid inlet pipe 231 is used to pass the spray liquid, so that the spray liquid can be sprayed out from the spray head 232. In this way, the smoke generated by the waste incinerator enters the spray box 21 through the air inlet pipe 22 and moves along the first horizontal direction. After being sprayed by multiple spray heads 232, it escapes from the liquid outlet 211, thereby washing away the fly ash in the smoke. The waste water formed flows out from the liquid outlet 211, and the receiving bucket 51 is used to receive the waste water flowing out of the liquid outlet 211.

[0038] In this embodiment, the bottom wall of the spray box 21 is inclined, and the bottom end of the bottom wall of the spray box 21 is located at the liquid outlet 211, so that the waste water can smoothly flow out of the spray box 21. When the rotating shaft 31 rotates, a small amount of waste water will fall into the collecting pipe 34. Since the amount is small, it does not need to be processed. Of course, a container can also be used to receive this small amount of waste water and pour it into the receiving bucket 51.

[0039] In some embodiments, see Figure 1, Figure 3 and Figure 5 The waste incineration fly ash treatment device also includes a cooling box 6, a plurality of cooling fans 7 and an air outlet pipe 8. The cooling box 6 is fixedly mounted outside the air inlet pipe 22, and a plurality of cooling holes 61 are provided on the cooling box 6. The plurality of cooling fans 7 correspond to the plurality of cooling holes 61 one by one, and the cooling fans 7 are fixedly mounted on the cooling box 6 and cover the corresponding cooling holes 61. One end of the air outlet pipe 8 is fixedly connected to the cooling box 6 and communicated with the inside of the cooling box 6, and the air outlet pipe 8 has a vertical section 81 arranged vertically, and the other end of the air outlet pipe 8 is located on the vertical section 81 and arranged upward. Among them, the bottom wall of the receiving barrel 51 is provided with an air outlet 511, and the receiving unit also includes a docking pipe 56, which is vertically arranged and located above the vertical section 81. The docking pipe 56 is fixedly connected to the bottom surface of the receiving barrel 51 and is connected to the inside of the receiving barrel 51. When the rotating assembly rotates to make the receiving barrel 51 after receiving the wastewater rotate to the next workstation, the docking pipe 56 on the receiving barrel 51 is coaxially arranged with the vertical section 81.

[0040] At this time, a heavy metal chelating agent is added to the receiving barrel 51. When the wastewater in the receiving barrel 51 is completely precipitated, the piston rod of the hydraulic cylinder 52 drives the receiving barrel 51 to slide downward until the butt joint 56 is connected to the vertical section 81. Since the temperature of the flue gas is relatively high, the temperature of the intake pipe 22 will be relatively high when the flue gas passes through the intake pipe 22. The cooling fan 7 blows air into the cooling box 6 through the cooling hole 61, thereby taking away the heat on the intake pipe 22. The formed heat flow enters the receiving barrel 51 through the outlet pipe 8 and the butt joint 56, and then flows out of the receiving barrel 51 through the outlet hole 511. The heat in the heat flow passes through the lifting plate 53 and the side wall of the receiving barrel 51 to dry the sludge on the lifting plate 53. The dried sludge is convenient for transportation and processing. In this embodiment, when the sludge on the lifting plate 53 is dried, the lifting plate 53 is driven to slide out of the receiving barrel 51, and then the lifting shaft 55 is driven to exit the notch 541, and then the lifting plate 53 is taken to a suitable position to process the dried sludge.

[0041] In this embodiment, the lifting plate 53 and the lifting shaft 55 can be used as a replaceable component. When one of the replaceable components is withdrawn from the receiving unit, the other replaceable component is placed into the receiving unit.

[0042] In some embodiments, see Fig. 9 The garbage incineration fly ash treatment device also includes a first annular sealing gasket 9. The first annular sealing gasket 9 is coaxially arranged on the vertical section 81 and fixedly connected to the vertical section 81. When the butt-joint pipe 56 moves downward with the receiving barrel 51, the butt-joint pipe 56 can cooperate with the vertical section 81 to squeeze the first annular sealing gasket 9, thereby achieving the connection between the butt-joint pipe 56 and the vertical section 81 while ensuring the sealing between the butt-joint pipe 56 and the vertical section 81.

[0043] In some embodiments, the feature receiving unit may be used as follows: Figure 8 See the structure shown. Figure 8 The receiving unit further includes a second annular sealing gasket 57. The second annular sealing gasket 57 is located in the receiving barrel 51 and is circumferentially fitted and slidably fitted with the inner side surface of the receiving barrel 51. The second annular sealing gasket 57 is fixedly connected to the bottom surface of the lifting plate 53. The second annular sealing gasket 57 is used to achieve sealing between the lifting plate 53 and the inner side surface of the receiving barrel 51.

[0044] In some embodiments, the feature receiving unit may be used as follows: Figure 1 and Figure 2 See the structure shown. Figure 1 and Figure 2 The receiving unit further includes a support shaft 58 and a sliding member 59. The support shaft 58 is vertically arranged, and the upper and lower ends of the support shaft 58 are fixedly connected to the fixing member 54 and the first connecting plate 32 respectively. The sliding member 59 is slidably sleeved outside the support shaft 58 and is fixedly connected to the receiving barrel 51. The sliding member 59 can slide along the vertical direction with the receiving barrel 51, and the sliding member 59 can limit the rotation of the receiving barrel 51, and prevent the receiving barrel 51 from sliding off the first connecting plate 32. The deformation of the fixing member 54 can be limited by the support shaft 58.

[0045] In some embodiments, the above-mentioned characteristic rotating assembly can be used as follows Figure 1 and Figure 8 See the structure shown. Figure 1 and Figure 8 The rotating assembly further includes a supporting seal 35. The supporting seal 35 is sleeved outside all the receiving barrels 51 and the support shaft 58, and the supporting seal 35 is fitted and fixed to the first connecting plate 32. The supporting seal 35 can achieve sealing between the receiving barrel 51 and the first connecting plate 32.
