Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of environmental protection equipment, and in particular relates to a slag breaking and discharging device for a biomass incinerator. Background Art
[0002] Biomass incinerators are usually used to treat biomass waste, which comes from a wide range of sources, including kitchen waste, garden dead branches and leaves, farmland waste, waste fruits and vegetables from farmers' markets, etc. Biomass waste not only has a high moisture content, but also contains a variety of waste materials such as water phase, oil phase, solid phase, etc., with uneven and unstable shapes. These waste components are generally mixed together to form a semi-fluid paste with a large number of gaps in the middle of the paste, but the distribution is uneven. Usually, when a biomass incinerator is used to incinerate garbage, the biomass garbage is generally supported on a grate, and air is blown into the furnace to burn the organic matter in the biomass garbage. At present, the commonly used biomass incinerators have a relatively simple structure and are relatively easy to operate.
[0003] However, due to the complex composition and morphological structure of biomass waste, and the presence of some inorganic salt components, it is very easy to form larger slag or incompletely burned balls during the incineration process. These slag blocks reduce the effective space of the furnace, which not only greatly affects the efficiency of furnace combustion, making the incinerator unable to operate under normal conditions, but also may block the slag outlet, resulting in inability to operate continuously. On the other hand, the inorganic salt components in the garbage will be melted by the high temperature in the furnace and adhere to the grate. As the incinerator runs, the bonding layer becomes thicker and thicker. At this time, the furnace needs to be completely stopped and cooled before the bonding layer can be cleaned.
[0004] In order to solve the above problems, the current common practice is: 1) Before the biomass waste is incinerated, the materials are mixed and proportioned relatively evenly to make the pores in the waste more uniform and slag blocks are not easily formed during the combustion process, but this method increases the complexity of the early batching process; 2) Increase the blowing volume and blowing uniformity during the combustion process, but this method increases energy consumption and greatly increases the amount of waste gas generated; 3) Set up multiple layers of grates in the furnace to make the waste fully burn during the repeated movement on the multiple layers of grates, but this method increases the structural complexity of the incinerator and greatly increases the difficulty of its subsequent operation and maintenance; 4) Regularly shut down the furnace for maintenance and clean up the slag blocks, inorganic salts and other bonding layers. In summary, there is an urgent need for a slag breaking and slag discharging device for a biomass incinerator that has high working stability, is not easy to stick, has a simple structure, and does not require shutdown for maintenance.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0031] Example:
[0032] like Figure 1-Figure 3 As shown, the utility model provides a slag breaking and discharging device for a biomass incinerator, including a slag storage barrel 1, which is used to temporarily store slag blocks produced by incineration. The diameter of the slag storage barrel 1 can be the same as the slag dropping position of the incinerator, and the height can be set according to parameters such as the amount of slag blocks produced and the slag discharging speed; a slag leveling component 2 is arranged inside the slag storage barrel 1, and a slag breaking bucket 3 is arranged below the slag leveling component 2. The slag breaking bucket 3 is a bowl-shaped structure, and the angle between the edge of the slag breaking bucket 3 and the bottom is 110-130°. The slag storage barrel 1 is provided with a slag dropping bucket 4 below the slag breaking bucket 3, and the taper of the slag dropping bucket 4 is not more than 60°. A drive member connecting port 5 is opened on one side of the slag dropping bucket 4, and a transmission member 6 is arranged inside the drive member connecting port 5.
[0033] During processing, the incinerated slag blocks enter the slag storage barrel 1, and the position of the slag blocks is adjusted by the slag leveling component 2, and then the slag is broken through the slag breaking bucket 3 and discharged through the slag dropping bucket 4. The side driving connection port is convenient for connecting the external driving equipment with the slag leveling component 2 through the transmission part 6 to drive the equipment to work. In the entire slag breaking and discharging process, not only is the slag discharge efficiency high, but it is also not easy to have a bonding layer, there is no need to stop the furnace for cleaning, and it is easy to maintain and use.
[0034] The slag leveling assembly 2 includes a connecting rod 7 and a slag leveling plate 8. The connecting rod 7 is vertically placed inside the slag storage bucket 1. The rotation speed of the connecting rod 7 is adjustable. For biomass incineration slag blocks, the optimal rotation speed should be set to 5-15r / min. The slag leveling plate 8 is installed on the surface of the connecting rod 7. The slag leveling plate 8 is located above the slag breaking bucket 3 and is arranged in a single piece. According to the height of the slag storage bucket 1, one or more pieces can be arranged to evenly distribute the slag blocks in the slag storage bucket 1. The bottom of the connecting rod 7 is connected to the transmission member 6. The surface of the connecting rod 7 is connected with slag breaking teeth 9. The slag breaking teeth 9 are located inside the slag breaking bucket 3 and are symmetrically arranged, with 2-8 pieces. The upper and lower parts have sharp teeth for slag breaking. The angle of the upper sharp teeth of the slag breaking teeth 9 is 15-20°, and the angle of the lower sharp teeth is 35-40°.
[0035] Driven by the connecting rod 7, the slag leveling plate 8 drives the slag blocks to rotate and fall in layers, which will not cause the slag to remain in the furnace for a long time and harden and compact, and there is no need to stop the furnace for cleaning. On the other hand, while breaking and discharging the slag, it will not affect the working condition of the incinerator. The slag breaking teeth 9 can cooperate with the slag breaking bucket 3 to break the slag blocks, and through the mutual friction with the bucket wall and the slag breaking bucket 3, the slag particles are broken into smaller particles and discharged from the slag storage bucket 1.
[0036] Reference Figure 3 The side wall of the slag hopper 3 is evenly provided with a plurality of square through holes 10 along its circumference, which are used for the outlet of the crushed slag particles. The size of the opening can be determined according to the diameter requirement of the slag particles finally collected, and the number of openings is determined according to the size of the slag storage bucket 1 and the slag discharge rate. A fixed connecting piece 11 is arranged at the bottom of the slag hopper 3, and a rotating bearing 12 is installed in the middle of the slag hopper 3. The square through holes 10 are convenient for timely discharge of the slag blocks after slag breaking to ensure work efficiency.

The connecting rod 7 is connected to the slag hopper 3 through the rotating bearing 12, and the rotating bearing 12 can improve the stability of the connection between the connecting rod 7 and the slag hopper 3.
