Description

Technical Field

[0001] This application relates to the field of fly ash treatment, and in particular to a fly ash storage device for an incinerator. Background Technology

[0002] With the increasing amount of household waste, in order to avoid its environmental impact and to make full use of the resources it contains, more and more waste treatment methods are being applied to the daily processing of household waste. Currently, the main method of household waste treatment is waste-to-energy incineration. This involves burning household waste and using the heat generated during the incineration process to generate electricity, thereby achieving the recycling and reuse of waste resources.

[0003] Currently, waste incineration is mainly carried out using waste incinerators. During the incineration process, fine dust particles are produced, known as fly ash. Currently, fly ash is often collected by adding water, mixing the fly ash with water, and then processing it centrally.

[0004] However, when processing fly ash, it is necessary to first dry the fly ash to remove the water. Since the water in the fly ash is mixed with the fly ash for a long time, it is inevitable that there will be harmful substances. Simply drying it can easily cause the harmful substances in the water to disperse into the air and pollute the surrounding air. Utility Model Content

[0005] In order to reduce the pollution to the surrounding environment during fly ash treatment, this application provides a fly ash storage device for incinerators.

[0006] The incinerator fly ash storage device provided in this application adopts the following technical solution: A fly ash storage device for an incinerator includes a collection box, a feed pipe connected to the top of the collection box, multiple nozzles for spraying water into the collection box connected to the top of the collection box, a storage box on one side of the collection box, the collection box and the storage box being connected by a feeding assembly, the feeding assembly being used to transport the fly ash inside the collection box to the storage box, a filter plate being provided inside the storage box, and a sedimentation tank being connected to one side of the storage box.

[0007] By adopting the above technical solution, fly ash is guided into the collection box through the feed pipe, and then water is sprayed onto the fly ash through the nozzle. The fly ash mixed with water is then guided into the storage box through the feeding assembly for filtration, thereby separating the excess water mixed in the fly ash. This reduces the occurrence of fly ash treatment processes being affected by a large amount of water mixed in with the fly ash.

[0008] Optionally, the feeding assembly includes a feeding auger located at the bottom of the collection box, the end of the feeding auger penetrating through the side wall of the collection box and the adjacent storage box and inserted into the interior of the storage box, and one end of the feeding auger is connected to a feeding motor.

[0009] By adopting the above technical solution, when it is necessary to feed the fly ash inside the collection box, the feeding motor drives the feeding auger to rotate, and the feeding auger moves the fly ash into the storage box during the rotation process.

[0010] Optionally, the inside of the collection box is provided with a scraping component on the upper side of the filter plate for scraping the material on the filter plate.

[0011] By adopting the above technical solution, when fly ash falls onto the upper side of the filter plate, the scraping component scrapes the fly ash on the filter plate to level it, thereby reducing the phenomenon that fly ash accumulation on the filter plate makes it difficult for water in the fly ash to penetrate the filter plate.

[0012] Optionally, the scraping assembly includes a scraper plate located on the upper side of the filter plate, and the scraper plate is connected to a scraper electric actuator for moving the scraper plate on the upper side of the filter plate.

[0013] By adopting the above technical solution, the scraper electric actuator is activated, which drives the scraper plate to move. During the movement of the scraper plate, the fly ash on the filter plate moves, thereby achieving the scraping and leveling operation of the fly ash on the filter plate.

[0014] Optionally, a plurality of scraper springs are connected between the scraper and the scraper electric actuator.

[0015] By adopting the above technical solution, the scraper push rod and the scraper plate are connected by a spring, which reduces the phenomenon that the scraper plate will be damaged due to longitudinal displacement caused by the depression on the surface of the fly ash during the process of the scraper plate moving the fly ash.

[0016] Optionally, a plurality of compression springs are connected between the lower side wall of the filter plate and the inner bottom wall of the opposite collection box, and a vibration assembly for vibrating the filter plate is connected to the lower side of the filter plate.

[0017] By adopting the above technical solution, after the fly ash falls onto the upper side of the filter plate, the process of water droplets falling off the filter plate can be accelerated by the vibration component in conjunction with the compression spring located on the lower side of the filter plate, thereby speeding up the operation of fly ash treatment inside the filter plate.

[0018] Optionally, the vibration assembly includes a vibration cam located on the lower side of the filter plate. The vibration cam can abut against the lower side wall of the filter plate during rotation. A vibration motor for driving the vibration cam to rotate is connected to one side of the vibration cam.

[0019] By adopting the above technical solution, when it is necessary to vibrate the filter plate, the vibrating motor is turned on to drive the vibrating cam to rotate. During the rotation of the vibrating cam, it comes into contact with the filter plate, thereby realizing the vibration operation of the filter plate.

[0020] Optionally, an opening is provided on one side wall of the storage box, and a discharge door for sealing the opening is provided at the opening.

[0021] By adopting the above technical solution, when it is necessary to clean the fly ash inside the storage box, the discharge door can be opened, which makes it convenient for staff to clean the fly ash on the filter plate.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up storage boxes and filter plates, it is possible to separate the moisture mixed in with fly ash, thereby facilitating the subsequent treatment of fly ash by staff. 2. By setting up a scraper assembly, the fly ash on the filter plate can be filtered more evenly; 3. By setting up a vibrating assembly, the process of separating fly ash and water on the filter plate can be accelerated. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3This application will be described in further detail.

[0028] This application discloses an incinerator fly ash storage device, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a collection box 1, the top wall of which is penetrated and fixedly connected to a feed pipe 11. One end of the feed pipe 11 is inserted into the inside of the collection box 1 and connected to a conical block. The tip of the conical block is inserted into the inside of the feed pipe 11 and there is a gap between the side wall of the conical block and the inner wall of the adjacent feed pipe 11.

[0029] A water tank 12 is provided on the upper side of the collection box 1. The water tank 12 is arranged around the feed pipe 11. Multiple nozzles 13 are connected to the lower side of the water tank 12. Each nozzle 13 is located inside the collection box 1 and is evenly distributed around the feed pipe 11.

[0030] A storage box 2 is located below one side of the collection box 1, and the upper end of one side wall of the storage box 2 abuts against the outer wall of the adjacent collection box 1. The collection box 1 and the storage box 2 are connected by a feeding assembly 3. The feeding assembly 3 is used to transport the fly ash inside the collection box 1 to the inside of the storage box 2. A filter plate 21 is located inside the storage box 2 below the feeding assembly 3.

[0031] A sedimentation tank 4 is provided on one side of the storage tank 2. A liquid outlet pipe 22 is connected to the side wall of the storage tank 2 near the sedimentation tank 4, and the connection point between the liquid outlet pipe 22 and the storage tank 2 is located below the filter plate 21. The end of the liquid outlet pipe 22 away from the storage tank 2 is connected to the upper end of the side wall of the adjacent sedimentation tank 4, and a pump body 23 and a valve 24 are installed on the liquid outlet pipe 22. A discharge gate 25 is provided on one side of the sedimentation tank 4.

[0032] A pipe is connected to the side of the sedimentation tank 4 away from the outlet pipe 22, and the pipe is located below the horizontal plane where the outlet pipe 22 is located.

[0033] When incinerator fly ash needs to be treated, the fly ash is guided into the collection box 1 through the feed pipe 11. Then, water is sprayed into the fly ash inside the collection box 1 through the nozzle 13, causing the fly ash and water to combine and settle to the bottom of the collection box 1. The fly ash is then delivered to the storage box 2 through the feeding assembly 3. Inside the storage box 2, the fly ash falls onto the upper side of the filter plate 21, while the water mixed in with the fly ash falls onto the lower side of the filter plate 21 and is guided into the sedimentation tank through the liquid outlet pipe 22. After sedimentation, the suspension is discharged from a pipe on one side of the sedimentation tank. By separating the water from the fly ash, it is possible to facilitate fly ash collection and also separate excess water from the fly ash, thus simplifying the subsequent fly ash treatment process.

[0034] The two opposing side walls of the collection box 1 are gradually inclined towards the middle from top to bottom, and the bottoms of the two inclined side walls are connected by an arc-shaped bottom wall. The feeding assembly 3 includes a feeding auger 31 located inside the collection box and capable of abutting against the arc-shaped inner bottom wall. An opening is provided on the side wall of the collection box 1 adjacent to the storage box 2, and the feeding auger 31 passes through the opening and is inserted into the storage box 2. A feeding motor 32 and a feeding reducer 33 are connected to the end of the feeding auger 31 away from the storage box 2.

[0035] After the fly ash comes into contact with water, it falls to the bottom of the collection box 1. Then the feeding motor 32 is turned on, and the feeding motor 32 drives the feeding auger 31 to move the fly ash inside the collection box 1 toward the inside of the storage box 2, thereby realizing the transportation operation of the fly ash.

[0036] The filter plate 21 is also provided with a scraping assembly 5 for scraping the material on the filter plate 21.

[0037] By setting the scraper assembly 5, the fly ash can be distributed more evenly on the filter plate 21, so that the water mixed in the fly ash can fall evenly into the lower side of the filter plate 21.

[0038] The scraping assembly 5 includes a vertically arranged scraper plate 51 located above the filter plate 21. A horizontally arranged connecting plate 52 is provided above the scraper plate 51, with its length direction parallel to the length direction of the scraper plate 51. Multiple scraper springs 53 connect the connecting plate 52 and the scraper plate 51. Each end of the connecting plate 52 penetrates the side wall of an adjacent collection box 1 and is slidably connected to the side wall of the collection box 1 it penetrates in the horizontal direction. The moving direction of the connecting plate 52 is perpendicular to its own length direction. A horizontally arranged scraper electric actuator 54 is hinged to each end of the connecting plate 52 outside the collection box 1, with the length direction of each scraper electric actuator 54 parallel to the moving direction of the connecting plate 52.

[0039] After the material falls onto the upper side of the filter plate 21, the two scraper electric actuators 54 are activated. The two scraper electric actuators 54 simultaneously drive the connecting plate 52 and the scraper plate 51 to move. During the movement, the scraper plate 51 drives the fly ash on the upper side of the filter plate 21 to move and flatten the fly ash.

[0040] Multiple vertically arranged compression springs 26 are fixedly connected to the lower side of the filter plate 21. The multiple compression springs 26 are evenly distributed on the lower side of the filter plate 21, and the end of each compression spring 26 away from the filter plate 21 is fixedly connected to the inner bottom wall of the storage box 2.

[0041] A vibration assembly 6 is provided on the lower side of the filter plate 21. The vibration assembly 6 is used to drive the filter plate 21 to perform vibration operation.

[0042] When fly ash falls onto the upper side of filter plate 21, the vibrating component 6 drives the filter plate 21 to vibrate, and the leveling component is used to level it, so that the water mixed in the fly ash on the upper side of filter plate 21 can quickly pass through filter plate 21 and drip into the storage box 2.

[0043] The vibrating assembly 6 includes a vibrating cam 61 located on one side of the bottom of the filter plate 21. When the filter plate 21 is filled with fly ash, the vibrating cam 61 can abut against the filter plate 21 during rotation. A vibrating motor 62 is provided on the outer wall of the storage box 2 near the vibrating cam 61. The vibrating motor 62 is connected to the vibrating cam 61 through a vibrating reducer 63 and drives the vibrating cam 61 to rotate.

[0044] When it is necessary to vibrate the fly ash on the upper side of the filter plate 21, the vibrating motor 62 is turned on and the vibrating reducer 63 drives the vibrating cam 61 to rotate. During the rotation, the vibrating cam 61 drives the filter plate 21 to vibrate, thereby accelerating the filtration process of water mixed in the fly ash on the filter plate 21.

[0045] The implementation principle of the incinerator fly ash storage device in this application embodiment is as follows: the fly ash is guided into the collection box 1 through the feed pipe 11, and then water is sprayed on the fly ash through the nozzle 13 to reduce dust during the transportation of fly ash.

[0046] Then, the fly ash and water are moved to the storage tank 2 by the feeding auger 31 to filter the excess water mixed in the fly ash. The filtered water enters the sedimentation tank 4 for sedimentation, and the remaining fly ash impurities are taken out from the discharge gate 25 for centralized treatment.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
