Description

Technical Field

[0002] Biomass reciprocating grate organic heat carrier boilers typically consist of an upper body and a lower grate, employing an assembled forced circulation chain grate (reciprocating grate). The boiler has a compact structure, small footprint, short installation period, and low installation cost. The boiler body's radiant heating surface uses a single furnace or closely spaced square coils, with a serpentine convection heat exchange tube configuration at the rear. Based on fuel characteristics, a special anti-ash accumulation structure is used to reduce ash buildup and facilitate cleaning. The boiler's convection heat exchange section utilizes staggered heights, increased spacing, and soot blowing devices to reduce ash accumulation and improve boiler efficiency.

[0003] Currently, in practical use, biomass reciprocating grate organic heat carrier boilers still require manual addition of biomass fuel, resulting in low overall efficiency and increased workload for personnel. Therefore, this application proposes a biomass reciprocating grate organic heat carrier boiler with a spiral feeding mechanism. Utility Model Content

[0029] Please see Figures 1-5 This utility model provides a technical solution: a biomass reciprocating grate organic heat carrier boiler with a spiral feeding mechanism, comprising:

[0030] The base 100 and the biomass organic heat carrier boiler body 200 fixed on the upper surface of the base 100;

[0031] The feeding assembly 300 is used to transport biomass materials into the interior of the biomass organic heat carrier boiler body 200. The feeding assembly 300 includes a storage cylinder 301 fixed to the outer surface of the biomass organic heat carrier boiler body 200 by a mounting rod, and an L-shaped feeding pipe 302 disposed at the bottom end of the storage cylinder 301 and extending into the interior of the biomass organic heat carrier boiler body 200. A vertical rod 303 is rotatably disposed on the inner top wall of the storage cylinder 301, and a horizontal rod 304 is rotatably disposed on the inner wall of the horizontal tube of the L-shaped feeding pipe 302. Vertical spiral conveying blades 305 and horizontal spiral conveying blades 306 are respectively fixed on the surfaces of the vertical rod 303 and the horizontal rod 304. The feeding assembly 300 also includes a drive motor 307 disposed on the upper surface of the storage cylinder 301 for driving the vertical rod 303 and the horizontal rod 304 to rotate.

[0032] See Figure 4 The upper surface of the storage cylinder 301 has two symmetrical feeding ports 308, and a fixed box 309 is fixedly installed on the upper surface of the storage cylinder 301, and the drive motor 307 is fixedly installed on the upper surface of the fixed box 309.

[0033] Specifically, by setting up the feeding port 308, it is easy to add biomass fuel into the storage cylinder 301 for storage.

[0034] See Figure 4 The top end of the vertical rod 303 extends into the interior of the fixed box 309, and the output end of the drive motor 307 extends into the interior of the fixed box 309 and is fixedly connected to the top end of the vertical rod 303.

[0035] Specifically, by setting up a drive motor 307, the vertical rod 303 can be automatically rotated by the rotation of the drive motor 307.

[0036] See Figure 4 The inner side wall of the fixed box 309 is rotatably provided with a connecting rod 3010 extending to the outer surface of the fixed box 309. The end of the connecting rod 3010 and the surface of the vertical rod 303 are both fixed with bevel gears 3011 that mesh with each other.

[0037] Specifically, by setting a bevel gear 3011, the connecting rod 3010 can be automatically rotated by the rotation of the vertical rod 303.

[0038] See Figure 3 and Figure 4 One end of the crossbar 304 extends to the outer surface of the L-shaped feed pipe 302, and both the connecting rod 3010 and the crossbar 304 are fixed with drive wheels 3012, and the surfaces of the two drive wheels 3012 are fitted with drive belts 3013.

[0039] Specifically, by setting up the transmission wheel 3012 and the transmission belt 3013, the crossbar 304 can be automatically rotated by the rotation of the connecting rod 3010.

[0040] See Figure 3 Two symmetrical scrapers 3014 are fixed on the surface of the vertical rod 303, and the outer surfaces of the two scrapers 3014 are slidably connected to the inner wall of the storage cylinder 301.

[0041] Specifically, by setting scraper 3014, the two scrapers 3014 can be driven to scrape and clean the biomass fuel on the inner wall of storage cylinder 301 during the rotation of vertical rod 303.

[0042] In this invention, by setting up a feeding assembly 300, when the biomass reciprocating grate organic heat carrier boiler needs to be fed during actual use, the drive motor 307 can be started to drive the vertical rod 303 to rotate. The rotation of the vertical rod 303 drives the connecting rod 3010 to rotate under the action of two bevel gears 3011. The rotation of the connecting rod 3010 drives the horizontal rod 304 to rotate under the action of two transmission wheels 3012 and transmission belt 3013. Thus, when the vertical rod 303 rotates, it can transport the biomass fuel inside the storage cylinder 301 downward to the L-shaped feed pipe 302. At the same time, the rotation of the horizontal rod 304 can transport the biomass fuel entering the L-shaped feed pipe 302 laterally to the interior of the biomass organic heat carrier boiler body 200, thereby achieving the purpose of automatic feeding and effectively improving working efficiency.

[0043] See Figure 5 The surface of the L-shaped feed pipe 302 is provided with a sealing assembly 400. The sealing assembly 400 includes a sealing box 401 fixed on the surface of the L-shaped feed pipe 302 near the biomass organic heat carrier boiler body 200, and a sealing block 402 slidably disposed on the inner wall of the sealing box 401. The top of the sealing block 402 has a blade-shaped structure, and a limiting plate 403 is also slidably disposed on the inner wall of the sealing box 401. A return spring 404 is fixed between the upper surface of the limiting plate 403 and the inner top wall of the sealing box 401.

[0044] Specifically, by setting the blocking block 402, the L-shaped feed pipe 302 can be effectively blocked.

[0045] See Figure 5 A rotary motor 405 is fixedly mounted on the lower surface of the sealing box 401, and the output end of the rotary motor 405 extends into the interior of the sealing box 401 and is fixedly mounted with a threaded post 406. A cylindrical threaded groove 407 is opened on the lower surface of the sealing block 402, which is threadedly connected to the outer surface of the threaded post 406.

[0046] Specifically, by setting a rotary motor 405 and a threaded column 406, the rotation of the rotary motor 405 can drive the threaded column 406 to rotate, thereby driving the sealing block 402 to move automatically under the action of the cylindrical threaded groove 407.

[0047] In this invention, by setting up a sealing component 400, after the feeding is completed, the rotary motor 405 can be started to drive the threaded column 406 to rotate. The rotation of the threaded column 406 drives the sealing block 402 to move automatically upward under the action of the cylindrical threaded groove 407, thereby sealing the L-shaped feed pipe 302 and preventing heat leakage during the operation of the biomass organic heat carrier boiler body 200.

[0048] Working Principle: In actual use, when feeding is required, the drive motor 307 is activated to rotate the vertical rod 303. The rotation of the vertical rod 303, under the action of two bevel gears 3011, drives the connecting rod 3010 to rotate. The rotation of the connecting rod 3010, under the action of two transmission wheels 3012 and a transmission belt 3013, drives the horizontal rod 304 to rotate. This allows the vertical rod 303 to convey the biomass fuel inside the storage cylinder 301 downwards into the L-shaped feed pipe 302, while the horizontal rod 3014... The rotation of motor 405 can laterally transport the biomass fuel entering the L-shaped feed pipe 302 to the interior of the biomass organic heat carrier boiler body 200, thereby achieving automatic feeding and effectively improving work efficiency. After feeding is completed, the rotary motor 405 can be started to drive the threaded column 406 to rotate. The rotation of the threaded column 406 drives the sealing block 402 to move automatically upward under the action of the cylindrical threaded groove 407, sealing the L-shaped feed pipe 302 and preventing heat leakage during the operation of the biomass organic heat carrier boiler body 200.

[0049] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
