Description

Technical Field

[0001] The invention relates to the technical field of waste incineration fly ash treatment, and in particular to a waste incineration fly ash comprehensive treatment device and treatment process. Background Art

[0002] After the incineration of garbage, a large amount of fly ash will be generated. The fly ash contains a large amount of heavy metals and harmful organic matter (mainly dioxins). Direct landfill and other treatment methods will cause great environmental pollution. The fly ash solidification treatment method is a relatively mainstream fly ash treatment method. By adding agents, auxiliary materials and water to the fly ash, the fly ash is mixed and solidified to form a solidified body, which is then landfilled, thereby effectively avoiding dust pollution, reducing the dissolution of heavy metals and the seepage of harmful organic matter; For example, the existing public document CN104607434B - A method for solidifying fly ash from incineration of domestic waste and the existing public document CN105478449A - A system for solidifying fly ash from incineration of waste, both disclose a technology related to solidifying treatment of fly ash after waste incineration. Although the existing solidifying treatment method for waste fly ash can achieve effective treatment of fly ash after waste incineration, the above treatment method still has the following deficiencies in actual use: 1. In the existing curing treatment method, before the stirring reaction, the staff needs to weigh the various ingredients by themselves, and then add the ingredients to the stirring device according to the weighed ratio for sufficient stirring. However, this design method has high labor intensity and high production costs, and indirectly causes dust in the production workshop; 2. In the existing solidification treatment method, the staff transports the raw materials into the mixing device through the conveying device, but the fly ash and other raw materials may have problems such as adhesion and agglomeration. If they are added directly without treatment, it will cause insufficient mixing, and the liquid auxiliary agent also needs to be stirred and mixed separately, which increases the labor intensity; Therefore, it is necessary to improve the prior art to solve the above-mentioned technical problems. Summary of the invention

[0003] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0004] In view of the problem that the above-mentioned existing fly ash treatment equipment needs to weigh various raw materials separately before stirring the reaction, which increases the labor intensity and indirectly increases the production cost, a comprehensive treatment equipment for waste incineration fly ash is proposed.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a comprehensive treatment equipment for fly ash from garbage incineration, comprising a fly ash bin, a cement bin, a chelating agent raw liquid tank, a water tank, a mixing treatment device and a ton bag packaging machine, the mixing treatment device comprising an outer protection mechanism, including a batching box, a mixing box fixed on the bottom surface of the batching box and a cover plate fixedly fitted on the top surface of the batching box by bolts, a cylindrical cavity with a horizontal axis is opened in the middle of the batching box, and a rectangular cavity is opened on the top surface of the batching box, the rectangular cavity and the cylindrical cavity are connected by an opened feed trough, and the cylindrical cavity and the mixing box are connected by an opened feed trough; a batching mechanism arranged at the position of the cylindrical cavity comprises a rotating disk, a distance measuring sensor, a rectangular frame and a telescopic column, the rotating disk gap is fitted in the cylindrical cavity, a plurality of weighing troughs are opened on the side wall of the rotating disk along a circumferential array, and an air cavity is opened on a side of the weighing trough close to the center of the rotating disk, the rectangular frame is fixed to the outside of the opening end of the air cavity by bolts, and the inner side of the rectangular frame An airbag cloth is fixedly provided, and the air cavity is filled with gas. A middle-shaped groove connected with the cylindrical cavity is opened on the rotating disk on one side of the air cavity. The telescopic column is slidably sleeved in the middle of the middle-shaped groove, and a piston head is fixedly provided on the end of the telescopic column close to the air cavity. A piston ring is fitted on the side wall of the piston head. A spring is slidably sleeved on the outer side of the telescopic column. A distance sensor is fixedly sleeved on the batching box on the side of the cylindrical cavity close to the middle-shaped groove, and the projection of the distance sensor on the rotating disk is located on the rotating track surface of the middle-shaped groove. A rotating shaft is fixedly sleeved in the middle of the rotating disk, and both ends of the rotating shaft are rotatably sleeved on the batching box through rolling bearings; and a feeding mechanism arranged in the rectangular cavity includes a rectangular box frame, a screw rod, a rack plate and a stirring roller; two injection heads are arrayed on the top surfaces of the cover plates on both sides of the feed trough, wherein the two injection heads are respectively connected to the output ends of the fly ash bin and the cement bin through a screw conveyor, and the other two injection heads are respectively connected to the output ends of the chelating agent concentrate tank and the water tank through a self-priming pump.

[0006] The beneficial effects of the present invention are as follows: when the fly ash comprehensive treatment equipment is in use, the raw materials to be treated are guided by the rectangular box frame and enter the weighing trough on the rotating disk through the feed trough. After the raw materials to be treated fall into the weighing trough, they will squeeze the airbag cloth, thereby squeezing the gas in the air cavity. Under the action of the squeezing force, the piston head drives the telescopic column to move in the middle-shaped groove. At this time, the distance measuring sensor will detect the moving distance of the telescopic column, and the weighing of the raw materials to be treated can be achieved through conversion; through the independent arrangement of multiple weighing troughs, as the rotating disk rotates, each weighing trough is aligned with the upper feed trough one by one, so that each raw material to be treated can be weighed in the rotating disk. After the weighing is completed, as the rotating disk rotates, the raw materials to be treated will fall into the mixing box. Such an arrangement can realize the centralized weighing and processing of multiple raw materials to be treated, which is simple to operate, highly automated and reduces the cost of production equipment. The entire weighing method is located in a closed space, which effectively reduces the environmental pollution in the workshop.

[0012] In view of the problem that the existing processing equipment cannot effectively process the fly ash and other raw materials when they have problems such as adhesion and agglomeration, thereby affecting the subsequent mixing quality, a further preferred scheme improvement is made to a comprehensive processing equipment for waste incineration fly ash of the present invention, wherein: a rectangular box frame is gapped in the rectangular cavity, and a movable plate is fixedly provided in the middle of an outer side surface of the rectangular box frame, and two symmetrical side walls of the rectangular cavity are both provided with U-shaped cavities along the long side direction, and the movable plate is gapped in one of the U-shaped cavities; a screw rod is spirally sleeved on the movable plate, and both ends of the screw rod are rotatably sleeved on the batching box through rolling bearings, one end of the screw rod extends to the outside of the batching box and is embedded in the output end of the third motor, and the third motor is fixed on the outer wall of the batching box; a guide rod parallel to the screw rod is slidably sleeved on the movable plate, and both ends of the guide rod are fixed on the batching box.

A flow detector is provided on the delivery pipe of the self-priming pump to achieve metering of the chelating agent and water, thereby realizing the addition of fly ash, cement, chelating agent and water into the mixing box 102.

[0036] Reference Figure 1 , Figure 3 , Figure 4 and Fig.10 , which is the second embodiment of the present invention.

[0038] Furthermore, the bottom surface of the material storage cavity in the mixing box 102 is arranged in a circular arc surface, so as to improve the sufficient mixing.

[0039] A discharge trough 102d communicating with the material storage cavity is provided in the middle of the bottom surface of the mixing box 102, and a discharge plate 102c is provided in the gap in the discharge trough 102d. Extension plates 102c-2 are symmetrically fixed on both sides of the bottom surface of the discharge plate 102c, and a hydraulic cylinder 102c-3 is fixed in the middle of the top surface of the extension plate 102c-2. The fixed section of the hydraulic cylinder 102c-3 is fixedly connected to the outer wall of the mixing box 102 through the fixed plate 102b; a material conveyor is provided directly below the discharge trough 102d, and the output end of the material conveyor is connected to the input end of the ton bag packaging machine; When the above arrangement is in use, after the raw materials are sufficiently stirred and mixed, the discharge plate 102c can be extended by the hydraulic cylinder 102c-3 to move downward relative to the mixing box 102, and the discharge chute 102d is opened. In conjunction with the rotation of the stirring blade 102a-3, the material in the mixing box 102 can be discharged, and the discharged material is transported to the ton bag packaging machine by the material conveyor for subsequent bagging processing.

This arrangement can play a role of limiting and guiding the extension and retraction of the hydraulic cylinder 102c-3. Example 3

[0041] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 , which is the third embodiment of the present invention, is based on any of the above embodiments, except that, in order to achieve effective material transfer from the batching box 101 to the rotating disk 201 and facilitate better implementation of the present invention, this embodiment is proposed.

[0042] Specifically, the rectangular box frame 301 is loosely fitted in the rectangular cavity 101a, and a movable plate 301a is fixedly provided in the middle of one outer side surface of the rectangular box frame 301, and two symmetrical side walls of the rectangular cavity 101a are provided with U-shaped cavities 101e along the long side direction, and the movable plate 301a is loosely fitted in one of the U-shaped cavities 101e to guide the movement of the movable plate 301a; a screw rod 302 is spirally sleeved on the movable plate 301a, and both ends of the screw rod 302 are rotatably sleeved on the batching box 101 through rolling bearings, one end of the screw rod 302 extends to the outside of the batching box 101 and is embedded in the output end of the third motor 302a, and the third motor 302a is fixedly provided on the outer wall of the batching box 101; The movable plate 301a is slidably sleeved with a guide rod 301a-1 which is parallel to the screw rod 302, and both ends of the guide rod 301a-1 are fixed on the batching box 101. This arrangement can play a role of limiting and guiding the movement of the movable plate 301a. When the above arrangement is in use, the third motor 302a can be used to rotate the screw rod 302. Because the screw rod 302 and the movable plate 301a are screw-fitted, the rectangular box frame 301 can move back and forth in the axial direction of the screw rod 302, so that the rectangular box frame 301 can receive the material at the injection head 103a and then transfer the received material to the feed trough 101b. The rectangular box frame 301 can move along the axial direction of the screw rod 302 to cut and receive the material at the four injection heads 103a. In addition, it should be noted that, in actual use, in order to avoid the inability of the lower end of the rectangular box frame 301 to seal and transport the liquid due to the friction of the solid raw material, rectangular box frames 301 can be set on both sides of the feed trough 101b, and each rectangular box frame 301 is equipped with a screw rod 302 and a third motor 302a to realize the independent movement of the two rectangular box frames 301, and the liquid raw material and the solid raw material are respectively received and transported by the two rectangular box frames 301.

[0043] Furthermore, triangular shovel plates are symmetrically fixed at the lower ends of the two inner walls of the rectangular box frame 301, and the triangular shovel plates and the guide rod 301a-1 are vertically arranged on the same horizontal plane. The setting of the triangular shovel plates can shovel the bottom surface of the rectangular cavity 101a to avoid the accumulation and consolidation of raw materials and better transfer materials. Example 4

[0044] Reference Figure 4 , Figure 6 and Figure 7 , which is the fourth embodiment of the present invention, is based on the previous embodiment, except that this embodiment is proposed to avoid the cohesion of the raw materials and reduce the quality of subsequent stirring and to stir the liquid raw materials in another way.

[0045] Specifically, two parallel stirring rollers 304 are formed as a group, and multiple groups of stirring rollers 304 are arranged in an array along the axial direction of the guide rod 301a-1 at the inner lower end position of the rectangular box frame 301, and a rotating rod 304a is fixedly sleeved in the stirring roller 304, and the two ends of the rotating rod 304a are slidably sleeved on the inner wall of the rectangular box frame 301, and a second toothed disc 304a-1 is fixedly sleeved on the rotating rod 304a on one side of the stirring roller 304, and the two second toothed discs 304a-1 on the same group of stirring rollers 304 are meshed, and stirring bars 304b are evenly arranged on the outer side wall of the stirring roller 304, and the arrangement of the stirring bars 304b can crush the solid raw materials and mix the liquid raw materials; A rotating column 303a-1 is slidably sleeved in the middle of one side of the rectangular box frame 301, and a gear column 303a and a first toothed disc 303a-2 are respectively fixed at both ends of the rotating column 303a-1, the gear column 303a is meshed with a rack plate 303, and the rack plate 303 is fixed in another U-shaped cavity 101e; the first toothed disc 303a-2 is driven by a chain 303b and a second toothed disc 304a-1, and only one second toothed disc 304a-1 in the same set of stirring rollers 304 is meshed with the chain 303b; When the above arrangement is in use, when the rectangular box frame 301 moves along the axial direction of the screw rod 302, due to the meshing between the rack plate 303 and the gear column 303a, the gear column 303a can rotate itself while walking on the rack plate 303, thereby realizing the rotation of the first toothed disc 303a-2, and through the transmission of the chain 303b, one of the two second toothed discs 304a-1 in the same group can be rotated, and because of the meshing arrangement between the two second toothed discs 304a-1 in the same group, the two stirring rollers 304 in the same group can rotate towards or oppositely, thereby realizing stirring and crushing or stirring and mixing of the materials. Before adding materials, the rectangular box frame 301 can be placed on one side of the feed trough 101b for reciprocating motion to achieve stirring; In addition, it should be noted that when two rectangular boxes 301 are used, the gear columns 303 a on the two rectangular boxes 301 can share one rack plate 303 . Example 5

[0046] This embodiment is the fifth embodiment of the present invention. This embodiment provides a comprehensive treatment process for fly ash from garbage incineration. Specifically, the fly ash treatment is performed according to the following steps: S1: storing fly ash in a fly ash bin, inputting fly ash into the fly ash bin through a bucket elevator, storing cement in a cement bin, storing chelating agent in a chelating agent stock tank, and storing water in a water tank for standby use; S2: The chelating agent and water are fed into the rectangular box frame 301 through the injection head 103a according to the weight ratio by a self-priming pump, and the third motor 302a drives the rectangular box frame 301 to reciprocate so that the chelating agent and water are fully mixed to form a mixed liquid; S3: After being fully mixed, the mixed liquid is fed into the weighing tank 202b through the feed tank 101b as the rectangular box frame 301 moves for weighing; S4: After the weighing is completed, the rotating disk 201 starts to rotate so that another weighing trough 202b is facing the feeding trough 101b. When the mixed liquid in the rectangular box frame 301 is completely weighed, the rotating disk 201 starts to rotate to add the mixed liquid in each weighing trough 202b into the mixing box 102; S5: Based on the weight of the weighed mixed liquid, the fly ash is weighed and added through the screw conveyor in a predetermined ratio according to the operations of steps S2-S4, and then the mixed liquid and fly ash are stirred in the mixing box 102. If there is excess fly ash, it can be temporarily stored in the weighing tank 202b; S6: After the mixing is completed, the cement is weighed and added through the screw conveyor according to the operations of steps S2-S4, and is fully mixed in the mixing box 102. If there is excess cement, it can be temporarily stored in the rectangular box frame 301; S7: After the mixing is completed, the mixture is discharged from the bottom of the mixing box 102, and then the material conveyor conveys the mixture to the ton bag packaging machine for bagging, thereby completing the fly ash treatment.

[0047] It should be noted that the weighing of the above-mentioned raw materials should be based on the volume of the entire mixing box 102. Only after the weighing and feeding of one raw material is completed, the weighing and feeding of the next raw material can be carried out. The excess temporarily stored raw materials can be discharged after the mixing is completed, and the weight can also be recorded so that it can be added in advance when feeding next time.
