Description

Technical Field

[0001] This utility model relates to the field of sludge incineration treatment technology, specifically to an ash and slag separation device based on multi-source sludge co-incineration. Background Technology

[0002] Sludge co-incineration is a technology that mixes sludge with other combustible wastes (such as municipal solid waste, industrial solid waste, biomass, etc.) in a certain proportion and then incinerates them together in the same incineration system. Its core is to achieve efficient and stable operation of the incineration process by complementing the characteristics of different wastes (such as calorific value, composition, etc.) and simultaneously achieve the goals of volume reduction, harmlessness and resource recovery. When it is necessary to separate the ash residue after incineration, appropriate separation equipment is required.

[0003] However, the lack of corresponding auxiliary screening structures in the current ash and slag separation equipment makes it impossible to quickly separate ash and slag during the processing. As a result, a large amount of dust is attached to the slag during the collection process, which reduces the processing effect of the ash and slag separation equipment. Utility Model Content

[0025] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use.

[0026] 1. An internal dynamic ash and slag separation mechanism is installed. A drive motor continuously rotates the drive cam disc, which, in conjunction with the driven cam disc, causes the sliding inner frame to slide horizontally periodically. During this sliding, the return spring inside the limit sleeve is compressed and stores energy, ensuring that the sliding inner frame can drive the multi-layer screening mesh to periodically oscillate horizontally. This horizontal oscillation causes the furnace ash to fall through the top holes of the multi-layer screening mesh into the ash discharge hopper for discharge. The ash and slag intercepted by the multi-layer screening mesh are guided to the top of the slag discharge chute, and then discharged to the side of the separation and processing box. This achieves rapid ash and slag separation, effectively preventing the separated ash and slag from containing large amounts of dust that could affect subsequent processing, thus significantly improving the efficiency of the ash and slag separation equipment.

[0027] 2. A spray circulation dust suppression mechanism is installed. Spray water is stored on the side of the separation and treatment tank through a side water storage rectangular tank. Water is continuously supplied to the side water storage rectangular tank through a water supply jacking pipe. The spray water inside the side water storage rectangular tank is guided into the liquid guiding jacking pipe through the liquid guiding jacking pipe. The spray water is then guided into the liquid distribution frame through the liquid guiding jacking pipe. The spray water inside the liquid distribution frame is atomized and sprayed into the separation and treatment tank through water mist nozzles to assist in humidifying the ash and slag. This effectively reduces the dust generated during the operation of the separation and treatment tank and further improves the processing smoothness of the ash and slag separation equipment.

[0028] 3. A guided circulation dust removal mechanism is installed. The circulating fan draws airflow from the bottom collection pipe and generates a continuous airflow inside the top blowing pipe. The blowing frame generates a continuous downward airflow inside the separation and treatment box. The bottom collection frame collects the dust raised at the bottom of the ash discharge hopper and guides the collected dust back into the separation and treatment box through the blowing frame. This further reduces the dust generated during the operation of the ash and slag separation equipment and improves the overall environmental performance of the ash and slag separation equipment.

[0039] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0040] Example: Figure 1-4 As shown, this utility model provides a technical solution, an ash and slag separation device based on multi-source sludge co-incineration, including a separation and processing box 1, a feeding top hopper 2 embedded in the bottom of the inner side of the separation and processing box 1, and an ash discharge bottom hopper 3 embedded in the top of the inner side of the separation and processing box 1.

[0041] The separation and processing box 1 is equipped with an internal dynamic ash and slag separation mechanism 4;

[0042] The internal dynamic ash and slag separation mechanism 4 includes a guide mounting frame 401, a slag discharge guide channel 402, a sliding inner frame 403, a multi-layer screening screen 404, a drive motor 405, a drive convex disc 406, a limit sleeve 407, a reset spring 408, and a driven convex disc 409.

[0043] A guide frame 401 is embedded in the middle of the inner side of the separation and processing box 1, and a slag discharge guide channel 402 is fixedly connected to the middle of one side of the guide frame 401.

[0044] Inside the guide frame 401, a sliding inner frame 403 is slidably installed, and inside the sliding inner frame 403, multiple layers of screening screens 404 are fixedly connected at equal intervals from top to bottom;

[0045] A drive motor 405 is fixedly connected to the middle of one side of the separation processing box 1 via a suspension plate. The drive motor 405 is powered by an external power source, and a drive cam disk 406 is connected to the end of the output shaft of the drive motor 405.

[0046] A limiting sleeve 407 is fixedly connected to the middle of the other side of the separation processing box 1. A return spring 408 is fixedly connected to the middle of one end of the sliding inner frame 403 at the position corresponding to the inside of the limiting sleeve 407. A driven convex disk 409 is connected to the middle of the other end of the sliding inner frame 403 at the position corresponding to the side of the driving convex disk 406. The aperture of the multi-layer screening screen 404 decreases from top to bottom. The outer side of the sliding inner frame 403 is tightly slidably fitted with the inner wall of the guide mounting frame 401. The arc-shaped protrusions on the sides of the driving convex disk 406 and the driven convex disk 409 correspond to each other. The driving convex disk 406 is continuously rotated by the drive motor 405. The rotation of the driving convex disk 406, in conjunction with the driven convex disk 409, drives the sliding inner frame 403 to perform periodic rotation. The sliding inner frame 403 slides horizontally, and during the sliding process, the return spring 408 inside the limiting sleeve 407 is compressed and stored, thereby ensuring that the sliding inner frame 403 can drive the multi-layer screening screen 404 to periodically swing horizontally. During the horizontal swing of the multi-layer screening screen 404, the furnace ash falls down through the top holes of the multi-layer screening screen 404 into the ash discharge hopper 3 for discharge. The ash and slag intercepted by the multi-layer screening screen 404 are guided to the top of the slag discharge guide 402, and the ash and slag are discharged to the side of the separation and treatment box 1 through the slag discharge guide 402, thereby realizing the rapid separation of ash and slag, effectively preventing the ash and slag from containing a large amount of dust that affects subsequent processing, and thus effectively improving the use effect of the ash and slag separation equipment.

[0047] A spray circulation dust suppression mechanism 5 is installed on the outside of the separation and processing box 1;

[0048] The spray circulation dust suppression mechanism 5 includes a side water storage rectangular box 501, a water supply jacking pipe 502, a circulating spray pump 503, a liquid guiding jacking pipe 504, a liquid distribution frame 505, and a water mist nozzle 506.

[0049] A rectangular water storage box 501 is fixedly connected to the middle of one side of the outer side of the separation and treatment box 1, and a water supply pipe 502 is fixedly connected to the middle of the top surface of one side of the rectangular water storage box 501.

[0050] A circulating spray pump 503 is embedded in the middle of the top of the side water storage rectangular tank 501. The circulating spray pump 503 is powered by an external power source. A liquid guide pipe 504 is fixedly connected to the middle of the top of the circulating spray pump 503.

[0051] A liquid distribution frame 505 is fixedly connected to the end of the liquid guiding pipe 504 at the top edge of the separation and treatment tank 1. Water mist nozzles 506 are evenly and uniformly fixedly connected to the inner center of the liquid distribution frame 505. The bottom inlet of the circulating spray pump 503 is located below the liquid level inside the side water storage rectangular tank 501. The bottom surface of the liquid distribution frame 505 is fixedly connected to the top edge of the separation and treatment tank 1. Spray water is stored on the side of the separation and treatment tank 1 through the side water storage rectangular tank 501, and then supplied to the side water storage rectangular tank through the water supply pipe 502. Water is continuously supplied inside the tank 501. The spray water inside the side water storage rectangular tank 501 is introduced into the liquid guiding top pipe 504 through the circulating spray pump 503. The spray water is then introduced into the liquid distribution frame 505 through the liquid guiding top pipe 504. The spray water inside the liquid distribution frame 505 is atomized and sprayed into the separation and treatment tank 1 through the water mist nozzle 506 to assist in humidifying the ash and slag. This effectively reduces the dust generated during the operation of the separation and treatment tank 1 and further improves the processing smoothness of the ash and slag separation equipment.

[0052] A guide circulation dust removal mechanism 6 is provided on the outer side of the separation and processing box 1;

[0053] The guiding circulation dust removal mechanism 6 includes a circulating fan 601, a blowing top pipe 602, a blowing square frame 603, a collecting bottom pipe 604, and a collecting bottom frame 605;

[0054] A circulating fan 601 is fixedly connected to the bottom position of the limiting sleeve 407 on the outer side of the separation processing box 1. The circulating fan 601 is powered by an external power source.

[0055] A blowing pipe 602 is fixedly connected to the middle of the top of the circulating fan 601, and a blowing frame 603 is fixedly connected to the bottom of the outer side of the feeding hopper 2 at the end of the blowing pipe 602.

[0056] A collection bottom pipe 604 is fixedly connected to the middle of the bottom of the circulating fan 601. A collection bottom frame 605 is fixedly connected to the end of the collection bottom pipe 604 at the bottom position of the outer side of the ash discharge hopper 3. The inner ring of the blowing frame 603 is tightly fitted with the outer side of the feeding top hopper 2, and the inner ring of the collection bottom frame 605 is tightly fitted with the outer side of the ash discharge hopper 3. Air guide slots are evenly opened at the bottom of both the blowing frame 603 and the collection bottom frame 605. The circulating fan 601 draws the airflow inside the collection bottom pipe 604 and generates a continuous airflow inside the blowing top pipe 602. The blowing frame 603 generates a continuous downward airflow inside the separation treatment box 1. The collection bottom frame 605 collects the dust raised at the bottom of the ash discharge hopper 3 and reintroduces the collected dust into the separation treatment box 1 through the blowing frame 603. This further reduces the dust generated during the operation of the ash and slag separation equipment and improves the overall environmental performance of the ash and slag separation equipment.

[0057] The working principle and usage process of this utility model: In the actual application process, when it is necessary to process the ash residue generated during the co-incineration of sludge, the ash residue is added to the separation and processing box 1 through the feeding top hopper 2. After the ash residue falls into the sliding inner frame 403, the drive motor 405 drives the drive convex disk 406 to rotate continuously.

[0058] Then, by driving the rotation of the convex disk 406 in conjunction with the driven convex disk 409, the sliding inner frame 403 is driven to slide horizontally periodically. During the sliding of the sliding inner frame 403, the return spring 408 inside the limiting sleeve 407 is compressed and stored, thereby ensuring that the sliding inner frame 403 can drive the multi-layer screening screen 404 to swing horizontally periodically. During the horizontal swing of the multi-layer screening screen 404, the furnace ash falls down through the top holes of the multi-layer screening screen 404 into the ash discharge hopper 3 for discharge.

[0059] Then, the ash and slag intercepted by the multi-layer screening mesh 404 are guided to the top of the slag discharge guide 402, and the ash and slag are discharged to the side of the separation and treatment box 1 through the slag discharge guide 402, thereby realizing the rapid separation of ash and slag, effectively preventing the ash and slag after separation from containing a large amount of dust that affects subsequent processing, and thus effectively improving the performance of the ash and slag separation equipment.

[0060] When it is necessary to spray water to reduce dust inside the separation and treatment box 1, the spray water is stored on the side of the separation and treatment box 1 through the side water storage rectangular box 501, and water is continuously supplied to the side water storage rectangular box 501 through the water supply jack pipe 502. Then, the spray water inside the side water storage rectangular box 501 is introduced into the liquid guiding jack pipe 504 through the circulating spray pump 503, and then the spray water is introduced into the liquid distribution frame 505 through the liquid guiding jack pipe 504. Finally, the spray water inside the liquid distribution frame 505 is atomized and sprayed into the separation and treatment box 1 through the water mist nozzle 506 to assist in humidifying the ash and slag, thereby effectively reducing the dust generated during the operation of the separation and treatment box 1 and further improving the processing smoothness of the ash and slag separation equipment.

[0061] When a small amount of dust needs to be treated inside the separation treatment box 1 and at the end of the ash discharge hopper 3, the airflow inside the collection bottom pipe 604 is drawn by the circulating fan 601, and a continuous airflow is generated inside the blowing top pipe 602. Then, a continuous downward airflow is generated inside the separation treatment box 1 by the blowing frame 603. Next, the dust raised at the bottom of the ash discharge hopper 3 is collected by the collection bottom frame 605, and the collected dust is returned to the separation treatment box 1 through the blowing frame 603. This further reduces the dust generated during the operation of the ash and slag separation equipment and improves the overall environmental performance of the ash and slag separation equipment.

[0062] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
