Description

Technical Field

[0001] This utility model relates to the technical field of ash and slag treatment equipment, and in particular to an ash and slag treatment machine for biomass pellet combustion boilers. Background Technology

[0002] Biomass pellets are granular solid fuels produced by cold-forming and densifying crushed biomass straw, forestry waste, and other raw materials using pressure rollers and ring dies at room temperature. During the combustion of biomass pellets in a boiler, a certain amount of ash and slag will be generated. This ash and slag needs to be effectively collected and treated to ensure the normal operation of the boiler and environmental protection.

[0003] Biomass pellet fuel contains high levels of elements such as potassium, sodium, and silicon, and the ash residue after combustion can be further processed into fertilizer or building materials. The ash residue removed from the furnace needs to be crushed and pulverized. However, coking easily occurs in the furnace during biomass pellet combustion. The coke lumps harden after cooling, resulting in unsatisfactory pulverization and hindering subsequent processing operations.

[0004] To address the aforementioned problems, this utility model document proposes a biomass pellet combustion boiler ash and slag treatment machine. Utility Model Content

[0005] This utility model provides a biomass pellet combustion boiler ash and slag processing machine, which solves the problem that in the prior art, the ash and slag taken out from the furnace needs to be crushed and pulverized. However, during the combustion of biomass pellets, coking easily occurs in the furnace. The coked lumps harden after cooling, resulting in unsatisfactory pulverization effect and hindering subsequent processing operations.

[0006] This utility model provides the following technical solution:

[0007] A biomass pellet combustion boiler ash and slag treatment machine, comprising:

[0008] The box body has an open top, a feeding hopper is fixedly connected to a recess in the top of the box body, a base is fixedly connected to the bottom of the box body, and a first synchronous pulley and a second synchronous pulley are provided on the outside of the box body for matching use. The first synchronous pulley and the second synchronous pulley are connected to the same synchronous belt for transmission.

[0009] The crushing assembly, located inside the housing, is used to crush coke blocks;

[0010] The crushing component, located inside the chamber, is used to crush the broken coke blocks and improve the crushing effect;

[0011] The screening component, located inside the chamber, is used to screen the pulverized particles.

[0012] In one possible design, the crushing assembly includes two matching crushing rollers rotatably mounted on both ends of the inner wall of the housing. The crushing rollers are positioned near the top of the housing opening. One end of each crushing roller penetrates the outer wall of the housing and is fixedly connected to a first transmission gear. The two first transmission gears mesh with each other. A drive motor for driving one of the crushing rollers is fixedly mounted on the outer wall of the housing. The output shaft of the drive motor penetrates the inner wall of the housing and is fixedly connected to one end of the corresponding crushing roller. One end of the first synchronous pulley is fixedly connected to the center of one of the first transmission gears.

[0013] In one possible design, the crushing assembly includes two matching crushing rollers rotatably mounted on both ends of the inner wall of the housing. The crushing discs on the two crushing rollers are staggered. The crushing rollers are located below the crushing rollers. One end of the crushing roller penetrates the outer wall of the housing and is fixedly connected to a second transmission gear. The two second transmission gears mesh with each other. One end of the second synchronous pulley is fixedly connected to the center of one of the second transmission gears.

[0014] In one possible design, two rows of inserts are symmetrically fixedly connected to the inner wall of the box to improve the crushing effect between the crushing roller and the inner wall of the box. The distance between two adjacent inserts is the same as the distance between two adjacent crushing discs on the crushing roller. The arc opening of the inserts is set to fit against the outer wall between two adjacent crushing discs on the crushing roller.

[0015] In one possible design, the screening assembly includes a screen plate and a guide plate inserted into corresponding grooves on the inner wall of the housing. Both the screen plate and the guide plate are located below the rolling roller, with the guide plate located below the screen plate. The screen plate and the guide plate are inclined in opposite directions. A first discharge port is provided on the side wall of the housing near the lower part of the screen plate, and a second discharge port is provided on the side wall of the housing near the lower part of the guide plate. A first collection box and a second collection box are provided on the top of the base. The first collection box is located below the first discharge port, and the second collection box is located below the second discharge port.

[0016] In one possible design, a protective cover is detachably installed on the outer wall of the housing. The four corners of the protective cover are threadedly connected to the side wall of the housing by corresponding mounting bolts. The gear and the synchronous pulley are both located inside the protective cover. Multiple strip-shaped heat dissipation holes are equidistantly arranged on the side wall of the protective cover.

[0017] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0018] The working principle and usage process of this technical solution are as follows:

[0019] During use, the operator adds the ash and slag taken from the biomass pellet combustion boiler into the box through the feeding hopper. The design of the feeding hopper allows the ash and slag to enter the interior of the processor easily. After the ash and slag enter the box, the drive motor is started, which drives one of the crushing rollers to rotate. Since one end of each of the two crushing rollers is fixedly connected to a meshing first transmission gear, the other crushing roller will also rotate synchronously. The synchronous reverse rotation of the two crushing rollers will initially crush the coke in the ash and slag.

[0020] After being crushed, the ash falls into the crushing assembly below. Driven by a set of synchronous pulleys and a synchronous belt, the two crushing rollers rotate synchronously in opposite directions. Because the crushing discs on the crushing rollers are staggered, the ash is subjected to strong crushing action when it passes through, further refining the particles. At the same time, the inserts on the inner wall of the box also play an auxiliary crushing role. They can be inserted into the gap between the crushing rollers to improve the crushing effect and prevent the crushed coke from getting stuck in the gap between the crushing rollers and the inner wall of the box.

[0021] After being crushed, the ash and slag enter the screening assembly. The larger particles roll down the slope of the screen plate from the first discharge port into the first collection box, while the smaller waste particles pass through the screen holes of the screen plate and roll down the slope of the guide plate from the second discharge port into the second collection box, thus achieving particle size classification of the ash and slag.

[0022] This utility model has the following beneficial effects:

[0023] This invention, through the combined use of crushing and rolling components, can fully crush and roll coke lumps, resulting in finer ash particles and significantly improved pulverization effect; the design of the screening component enables the processor to classify the ash particles by size, facilitating subsequent processing operations.

[0024] The protective cover in this invention can effectively protect transmission components such as gears and timing pulleys, and prevent accidental injury to personnel during use. The strip-shaped heat dissipation holes on the protective cover are conducive to heat dissipation of the transmission components. Attached Figure Description

[0032] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0033] Example 1

[0034] Please refer to Figure 1-4 An ash and slag processing machine, comprising:

[0035] Box 1 is the main structure of the entire processor. Its top is designed to be unclosed, forming a notch for feeding. A feeding hopper 2 is fixedly connected in this notch to facilitate the addition of ash residue from biomass pellet combustion into the processor. A base 14 is fixedly connected to the bottom of box 1 to support the entire processor. In addition, a first synchronous pulley 9 and a second synchronous pulley 17 are provided on the outer wall of box 1 for matching use. These two synchronous pulleys are connected by the same synchronous belt 18 for transmission.

[0036] The crushing assembly, located inside the housing 1, is used to crush coke blocks. The crushing assembly mainly consists of two matching crushing rollers 3. These two crushing rollers 3 are rotatably mounted at both ends of the inner wall of the housing 1, near the top opening of the housing 1. One end of each crushing roller 3 penetrates the outer wall of the housing 1 and is fixedly connected to a first transmission gear 4. The two first transmission gears 4 mesh with each other. In order to drive one of the crushing rollers 3 to rotate, a drive motor 5 is fixedly installed on the outer wall of the housing 1. The output shaft of the motor penetrates the inner wall of the housing 1 and is fixedly connected to one end of the corresponding crushing roller 3. Through the transmission of the two first transmission gears 4, the two crushing rollers 3 can be rotated synchronously. At the same time, one end of the first synchronous wheel 9 is also fixedly connected to the center of one of the first transmission gears 4 so as to synchronously drive the crushing assembly to run.

[0037] The crushing assembly, located inside the housing 1, is used to crush the coke blocks after crushing, thereby improving the crushing effect. The crushing assembly mainly consists of two matching crushing rollers 6. These two crushing rollers 6 are rotatably installed at both ends of the inner wall of the housing 1 and located below the crushing roller 3. The crushing discs on the crushing rollers 6 are staggered to improve the crushing effect. One end of each crushing roller 6 penetrates the outer wall of the housing 1 and is fixedly connected to a second transmission gear 8. The two second transmission gears 8 also mesh with each other. Through the transmission of the two second transmission gears 8, the two crushing rollers 6 can be rotated synchronously. One end of the second synchronous pulley 17 is fixedly connected to the center of one of the second transmission gears 8. Through a set of synchronous pulleys and synchronous belt 18, the synchronous operation of the crushing assembly and the crushing assembly can be achieved.

[0038] To improve the crushing effect between the crushing roller 6 and the inner wall of the housing 1, two rows of inserts 7 are symmetrically fixed on the inner wall of the housing 1. The spacing between two adjacent inserts 7 is the same as the spacing between two adjacent crushing discs on the crushing roller 6. The arc of the insert 7 is fitted to the outer wall between two adjacent crushing discs on the crushing roller 6. This not only prevents the crushed coke from getting stuck in the gap between the crushing roller 6 and the inner wall of the housing 1, but also improves the crushing effect between the crushing roller 6 and the inner wall of the housing 1 by utilizing the cooperation between the inserts 7 and the crushing roller 6.

[0039] The screening assembly, located inside the housing 1, is used to screen the pulverized particles. The screening assembly mainly includes a screen plate 10 and a guide plate 12, which are inserted and installed in corresponding grooves on the inner wall of the housing 1. Both the screen plate 10 and the guide plate 12 are located below the rolling roller 6, and the guide plate 12 is located below the screen plate 10. The screen plate 10 and the guide plate 12 are both inclined, but in opposite directions. A first discharge port 11 is provided on the side wall of the housing 1 near the lower part of the screen plate 10, and a second discharge port 13 is provided on the side wall of the housing 1 near the lower part of the guide plate 12. At the top of the base 14, a first collection box 15 and a second collection box 16 are also provided, located below the first discharge port 11 and the second discharge port 13, respectively, for collecting ash and slag of different particle sizes.

[0040] This application can be used for the treatment of ash and slag from biomass pellet combustion boilers, and can also be used in other fields applicable to this application.
