Abstract
Description
Technical Field
[0001] This utility model relates to the field of slag discharge technology for combustion furnaces, and in particular to a slag discharge device for a biomass power generation straw combustion furnace. Background Technology
[0002] A combustion ash removal device is used in combustion equipment to discharge the waste ash produced after combustion. It typically consists of a ash discharge port, a conveying mechanism, and a crushing device. During combustion, the waste ash falls to the ash discharge port under gravity and is then transported to a designated location by a conveying mechanism such as a scraper or screw conveyor. Some ash removal devices are also equipped with crushing devices to break larger ash blocks into smaller particles for easier transportation and handling. Its role is crucial; it promptly removes the waste ash produced during combustion, ensuring the normal operation of the combustion equipment, improving combustion efficiency, reducing environmental pollution from waste ash, and extending the service life of the combustion equipment. It is widely used in various combustion equipment such as industrial boilers and waste incinerators. Currently, ash removal devices generate a large amount of combustion waste ash after straw combustion. Over time, the accumulation of this waste ash can cause blockages, preventing normal ash removal, thus requiring improvement. Utility Model Content

[0024] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a slag removal device for a biomass power generation straw combustion furnace.
[0025] A slag discharge device for a biomass power generation straw combustion furnace includes a support frame 1 and a bottom shell 2, the bottom shell 2 being disposed on the support frame 1. It also includes a transport mechanism disposed on the support frame 1 and the bottom shell 2 for straw input and slag discharge; and an anti-blocking mechanism disposed on the bottom shell 2 to prevent straw slag blockage. The anti-blocking mechanism includes: a combustion chamber 3 disposed on the bottom shell 2 for straw combustion; a baffle plate 4 disposed within the combustion chamber 3 and fixedly connected to it; a sliding plate 5 disposed within the combustion chamber 3 and slidably connected to it; a fixed frame 6 disposed on the combustion chamber 3 and fixedly connected to it; a first spring 7 disposed on the fixed frame 6 and fixedly connected to it; an mounting piece 8 disposed on the first spring 7 and fixedly connected to it; a push column 9 disposed on the mounting piece 8 and fixedly connected to it; and a roller 10 disposed on the mounting piece 8 and rotatably connected to it.
[0026] refer to Figure 3 and Figure 4 In a preferred embodiment, the anti-blocking mechanism further includes: a mounting part disposed on the combustion chamber 3 for component mounting; a driving part disposed on the mounting part for providing power; and a pushing part disposed on the combustion chamber 3 for pushing the sliding plate 5.
[0027] refer to Figure 2 and Figure 3 In a preferred embodiment, the mounting part includes: a mounting shell 11, which is disposed on the combustion chamber 3 and fixedly connected to the combustion chamber 3; and a fixing member 12, which is disposed on the mounting shell 11 and fixedly connected to the mounting shell 11.
[0028] refer to Figure 4 In a preferred embodiment, the driving unit includes: a first motor 13, which is disposed on the fixing member 12 and fixedly connected to the fixing member 12; a connecting shaft 14, which is disposed on the output end of the first motor 13 and fixedly connected to the output end of the first motor 13; and a cam 15, which is disposed on the connecting shaft 14 and fixedly connected to the connecting shaft 14.
[0029] refer to Figure 4 In a preferred embodiment, the pushing part includes: two connecting frames 16, which are disposed on the combustion chamber 3 and fixedly connected to the combustion chamber 3; and two second springs 17, which are disposed between the connecting frames 16 and the sliding plate 5 and fixedly connected to the connecting frames 16, and the second springs 17 are fixedly connected to the sliding plate 5.
[0030] With this configuration, the cam 15 can rotate together with the connecting shaft 14. When the cam 15 rotates, it can squeeze the roller 10. When the cam 15 cannot contact the roller 10, the roller 10 can continue to contact the cam 15 through the rebound of the first spring 7 and the second spring 17, so that the sliding plate 5 can move back and forth to shake the waste residue of straw burning, ensuring rapid feeding and preventing blockage.
[0031] refer to Figure 1 and Figure 5 In a preferred embodiment, the transport mechanism includes: a feed hopper 18, which is disposed on the support frame 1 and fixedly connected to the support frame 1; a connecting pipe 19, which is disposed on the feed hopper 18 and fixedly connected to the feed hopper 18; and a transport device, which is disposed on the bottom shell 2 and is used for slag discharge.
[0032] refer to Figure 1 and Figure 5 In a preferred embodiment, the transport mechanism includes: a connector 20 disposed on the bottom shell 2 and fixedly connected to the bottom shell 2; a second motor 21 disposed on the connector 20 and fixedly connected to the connector 20; and a screw rod 22 disposed on the output end of the second motor 21 and fixedly connected to the output end of the second motor 21.
[0033] This device, through its transport mechanism, can transport the waste residue generated during straw combustion, ensuring its timely discharge and preventing excessive accumulation. Furthermore, its anti-clogging mechanism ensures the waste residue falls smoothly, preventing blockages and guaranteeing the device's normal operation.
[0034] Working principle: When the device is working, the straw is transported to the combustion chamber 3 through the feed hopper 18 and the connecting pipe 19. The straw is burned. The waste residue produced by the burning of the straw on the baffle plate 4 in the combustion chamber 3 falls into the bottom shell 2 through the baffle plate 4. In the bottom shell 2, the second motor 21 drives the screw rod 22 to rotate, so that the waste residue entering the bottom shell 2 moves with the rotation of the screw rod 22 until the waste residue is discharged from the bottom shell 2 and collected. When the device burns straw, the first motor 13 starts intermittently. When the first motor 13 starts, it drives the connecting shaft 14 to rotate, which in turn drives the cam 15 to rotate. The cam 15 pushes the roller 10, which in turn squeezes the mounting piece 8. The mounting piece 8 then squeezes the first spring 7, which pushes the pushing column 9 against the sliding plate 5. This causes the sliding plate 5 to squeeze the second spring 17. When the cam 15 is not in enough contact with the roller 10, the first spring 7 and the second spring 17 rebound, keeping the roller 10 in contact with the cam 15. At the same time, the sliding plate 5 is pushed back, thus reciprocatingly pushing the waste residue from the straw burning, causing it to shake and allowing the waste residue to fall off quickly to prevent blockage.
[0035] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
