Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology for waste incineration, specifically a waste incineration fly ash source detoxification and slag collection device system. Background Technology

[0002] The fly ash produced after waste incineration needs to be detoxified at its source before it can be collected and utilized. This effectively avoids environmental pollution caused by fly ash from waste incineration and is beneficial to environmental protection and resource utilization.

[0003] Currently, existing slag aggregate production systems mainly include dosing equipment, mixing equipment, and briquetting machines. The dosing equipment is used to inject chlorine-fixing agents, heavy metal fixatives, and dioxin inhibitors into the waste incinerator grate before injecting the adsorbent and passivating agent into the filter bags. The mixing equipment is used to mix the detoxified ash with the adsorbent and passivating agent, water, and a small amount of auxiliary materials. The briquetting machine is used to compress the fully mixed detoxified ash into aggregate.

[0004] However, existing mixing devices often fail to achieve sufficient mixing when combining detoxifying ash, water, adsorption and passivation agents, and a small amount of auxiliary materials. This is because some of the detoxifying ash, water, adsorption and passivation agents, along with a small amount of auxiliary materials, settle at the bottom of the mixing chamber, thus affecting subsequent aggregate pressing. Furthermore, the bottom discharge of the flat-bottomed mixing chamber tends to leave residue, making unloading cumbersome. Therefore, a waste incineration fly ash source detoxification and slag aggregate preparation device system is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a waste incineration fly ash source detoxification and slag collection device system to solve the problem mentioned in the background art of insufficient mixing caused by the deposition of detoxification ash in the existing collection device system, which affects the system's working efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste incineration fly ash source detoxification and slag collection device system, including a dosing device, a mixing device, and a briquetting machine. The mixing device includes a U-shaped base frame, with side support columns rotatably connected to the inner left and right sides of the U-shaped base frame. A base plate is provided between the bottom ends of the two side support columns, and a motor is installed on the outer bottom surface of the base plate. The motor is connected to a mixing chamber assembly via a bottom rotating shaft. A top connecting shaft is provided between the top ends of the two side support columns, and a central shaft is connected to the top connecting shaft. Several mixing mesh plates are installed at one end of the central shaft inside the mixing chamber assembly.

[0007] Preferably, the stirring chamber assembly includes an intermediate chamber, an inverted funnel-shaped chamber, a funnel-shaped chamber, and a funnel-shaped feed chamber. The inverted funnel-shaped chamber is disposed on the upper side of the intermediate chamber, the funnel-shaped chamber is disposed on the lower side of the intermediate chamber, and the funnel-shaped feed chamber is disposed on the upper side of the inverted funnel-shaped chamber.

[0008] Preferably, the side support column is rotatably connected to the U-shaped base frame via an inner shaft, and the inner shaft passes through the side support column and is fixedly connected to the inner wall of the U-shaped base frame.

[0009] Preferably, the inner shaft is T-shaped, with the head of the inner shaft located inside the side support column, and the tail of the inner shaft fixedly connected to the inner wall of the U-shaped base frame.

[0010] Preferably, the height of the top connecting shaft is not lower than the height of the funnel-shaped feed chamber.

[0011] Preferably, the top connecting shaft is cylindrical and horizontally positioned.

[0012] Preferably, the central axis is set perpendicular to the top connecting axis.

[0013] Preferably, the inverted funnel-shaped cavity, the funnel-shaped cavity, and the funnel-shaped feed cavity are all configured as frustoconical shapes, and the intermediate cavity is configured as cylindrical.

[0014] Preferably, the central axis of the central shaft and the central axis of the funnel-shaped feed chamber are located on the same straight line.

[0015] Preferably, a plurality of mixing mesh plates are set on a central shaft by connecting blocks, and the plurality of mixing mesh plates are arranged at equal intervals around the central axis of the central shaft, and the side wall of the bottom plate is provided with pull rings.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This system, through the arrangement and cooperation of a U-shaped base frame, a base plate, and a mixing chamber assembly, utilizes the centrifugal force generated by the rotation of the mixing chamber assembly to throw the detoxifying ash, added water, and adsorbent / passivating agent from the bottom funnel-shaped cavity to the middle cavity. Combined with the layered blocking of the mixing mesh plate, this achieves thorough mixing of the detoxifying ash, water, and adsorbent / passivating agent, preventing their deposition on the inner bottom surface of the mixing chamber assembly.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0025] Reference Figure 1-4 As shown, this utility model provides a technical solution for a waste incineration fly ash source detoxification and slag collection device system:

[0026] A waste incineration fly ash source detoxification and slag collection device system includes a dosing device, a mixing device, and a briquetting machine. The mixing device includes a U-shaped base frame 1, with side support columns 21 rotatably connected to the inner left and inner right sides of the U-shaped base frame 1. A base plate 2 is provided between the bottom ends of the two side support columns 21. A motor 4 is provided on the outer bottom surface of the base plate 2. The motor 4 is connected to a mixing chamber assembly 5 through a bottom rotating shaft 41. A top connecting shaft 22 is provided between the top ends of the two side support columns 21. The top connecting shaft 22 is connected to a central shaft 3. Several mixing mesh plates 31 are provided at one end of the central shaft 3 located inside the mixing chamber assembly 5.

[0027] It should be further explained that this system is used to inject solidifying agents, heavy metal fixatives, and dioxin inhibitors into the grate of the waste incinerator via a dosing device. An adsorption and passivation agent is also sprayed before the filter bags to detoxify the fly ash at its source. The detoxified ash is then thoroughly mixed with the adsorption and passivation agent, water, and a small amount of auxiliary materials, and finally pressed into aggregate using a briquetting machine. This effectively avoids environmental pollution from fly ash generated during waste incineration and promotes resource utilization. The dosing device and briquetting machine are existing technologies and will not be described in detail here.

[0028] This system, through the arrangement and collaboration of a U-shaped base frame 1, a base plate 2, and a mixing chamber assembly 5, utilizes the centrifugal force generated by the rotation of the mixing chamber assembly 5 to throw the detoxifying ash, added water, and adsorption / passivation agents from the bottom funnel-shaped cavity 53 to the middle cavity 51. Combined with the layered blocking effect of the mixing mesh plate 31, this achieves thorough mixing of the detoxifying ash, water, and adsorption / passivation agents, preventing their deposition on the inner bottom surface of the mixing chamber assembly 5. The side support column 21 is rotatably connected to the U-shaped base frame 1, allowing the system to quickly unload the thoroughly mixed detoxifying ash by flipping the mixing chamber assembly 5. This improves the system's working efficiency. The structure is simple, efficient, and suitable for widespread application.

[0029] Among them, reference Figure 2 As shown, the stirring chamber assembly 5 includes an intermediate chamber 51, an inverted funnel-shaped chamber 52, a funnel-shaped chamber 53, and a funnel-shaped feed chamber 54. The inverted funnel-shaped chamber 52 is located on the upper side of the intermediate chamber 51, the funnel-shaped chamber 53 is located on the lower side of the intermediate chamber 51, and the funnel-shaped feed chamber 54 is located on the upper side of the inverted funnel-shaped chamber 52.

[0030] It should be further explained that the funnel-shaped cavity 53 is designed to facilitate the deposition of detoxifying ash, water, and adsorption passivating agents within it, which are then thrown to the intermediate cavity 51 when the stirring chamber assembly 5 rotates. The inverted funnel-shaped cavity 52 is designed to prevent the detoxifying ash, water, and adsorption passivating agents from splashing onto the outside of the stirring chamber assembly 5 during mixing. The funnel-shaped feed cavity 54 is designed to add detoxifying ash, water, and adsorption passivating agents to the inverted funnel-shaped cavity 52, the intermediate cavity 51, and the funnel-shaped cavity 53. The adsorption passivating agent is existing technology and will not be described in detail here.

[0031] Reference Figure 1-4 As shown, in an optional embodiment: the side support column 21 is rotatably connected to the U-shaped base frame 1 via the inner shaft 11. The inner shaft 11 passes through the side support column 21 and is fixedly connected to the inner wall of the U-shaped base frame 1. It should be noted that the inner shaft 11 is T-shaped, with the head of the inner shaft 11 located inside the side support column 21 and the tail of the inner shaft 11 fixedly connected to the inner wall of the U-shaped base frame 1.

[0032] Reference Figure 2 As shown, in an optional embodiment, the height of the top connecting shaft 22 is not lower than the height of the funnel-shaped feed chamber 54, so as to avoid interference between the top connecting shaft 22 and the funnel-shaped feed chamber 54.

[0033] Reference Figure 1 As shown, in an optional embodiment: the top connecting shaft 22 is set to a cylindrical shape and is set horizontally to minimize the length of the top connecting shaft 22, thereby reducing weight and facilitating the flipping of the bottom plate 2. Setting it to a cylindrical shape makes it less likely for the detoxification ash, which is fully mixed with water, adsorbent passivating agent, etc., to accumulate on the top connecting shaft 22 when the bottom plate 2 is flipped over for unloading.

[0034] Reference Figure 4 As shown, in an optional embodiment: the central axis 3 is positioned perpendicular to the top connecting axis 22. (Refer to...) Figure 1-4 As shown, in an optional embodiment: the inverted funnel-shaped cavity 52, the funnel-shaped cavity 53, and the funnel-shaped feed cavity 54 are all configured as frustoconical shapes, and the intermediate cavity 51 is configured as a cylinder. It should be noted that the central axis of the central shaft 3 and the central axis of the funnel-shaped feed cavity 54 are located on the same straight line. It should also be noted that several mixing screens 31 are mounted on the central shaft 3 via connecting blocks 32, and the several mixing screens 31 are evenly spaced around the central axis of the central shaft 3. The side wall of the bottom plate 2 is provided with pull rings 23, allowing the user to control the bottom plate 2 to flip and unload materials by pulling the pull rings 23.

[0035] The working principle of this invention will now be explained through its usage:

[0036] First, when using this device, refer to Figure 1 As shown, this is the initial state of the device during use. The operator pours the detoxified ash, which has been temporarily stored in the existing fly ash storage tank and detoxified at the source, into the mixing chamber assembly 5 through the funnel-shaped feed chamber 54. At the same time, water and a small amount of adsorbent and passivating agent are also poured in. The adsorbent and passivating agent and the small amount of auxiliary materials are existing technologies and will not be described in detail here. The motor 4 is started. The rotation of the output end of the motor 4 will drive the bottom rotating shaft 41 to rotate, which in turn drives the mixing chamber assembly 5 to rotate. The centrifugal force generated by the rotation of the mixing chamber assembly 5 throws the detoxified ash, water, adsorbent and passivating agent and the small amount of auxiliary materials inside from the funnel-shaped cavity 53 to the middle cavity 51. Since the central shaft 3 and the mixing screen 31 remain stationary, the detoxified ash, water, adsorbent and passivating agent and the small amount of auxiliary materials are fully mixed by the blocking of the mixing screen 31, which prevents them from settling on the inner bottom surface of the mixing chamber assembly 5. After a period of mixing, the unloading operation can be carried out.

[0037] By pulling the pull ring 23, the bottom plate 2 begins to rotate around the inner shaft 11, allowing the fully stirred detoxifying ash in the mixing chamber assembly 5 to be discharged from the funnel-shaped feed chamber 54. Since the inverted funnel-shaped chamber 52 is in the shape of a positive funnel at this time, it is even more conducive to the discharge of the detoxifying ash.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
