Description

Technical Field

[0001] This application relates to the field of waste heat recovery technology, and in particular to a slag waste heat recovery and ash discharge machine. Background Technology

[0002] Waste incinerators process waste by burning it. The ash produced after incineration still contains a lot of heat. Traditional ash removal devices only have simple mechanical conveying functions, which means that the sensible heat contained in the ash is not effectively utilized. This results in energy waste and the direct water cooling of the high-temperature ash generates a lot of steam that pollutes the working environment.

[0003] Publication (Announcement) No.: CN212481319U provides a waste heat recovery ash discharge machine, including a horizontal pipe, an inclined pipe, and a slag discharge pipe. The machine is characterized in that: the lower end of the inclined pipe is fixedly installed at the left end of the horizontal pipe by bolts; the upper end of the slag discharge pipe is fixedly installed at the upper left end of the inclined pipe by bolts, and the inclined pipe and the slag discharge pipe are connected; a drive wheel is rotatably installed at the left end of the horizontal pipe; a corner wheel is rotatably installed at the lower end of the inclined pipe; a top corner roller is rotatably installed at the upper left end of the slag discharge pipe; a chain conveyor belt is fitted between the drive wheel and the top corner roller, and the chain conveyor belt passes over the lower edge of the corner roller; and an ash collection hopper is fixedly installed at the upper end of the horizontal pipe. Through the operation of the ash collection hopper, most of the heat in the ash is recovered during the downward flow of the ash, achieving effective heat utilization and avoiding overheating of the ash and slag hot air, which could lead to excessively high working environment temperatures.

[0004] In existing technologies, when high-temperature ash falls, only the bottom contacts the heat exchange manifold, resulting in uneven waste heat recovery. Furthermore, high-temperature ash tends to agglomerate into lumpy coke, which means that only the outer surface can contact the heat exchange manifold, resulting in low waste heat recovery efficiency. Utility Model Content

Therefore, this invention proposes an ash waste heat recovery slag discharge machine.

[0024] The implementation principle of the ash and slag waste heat recovery slag discharge machine in this application embodiment is as follows: When in use, the ash and slag enter the dispersing chamber 6 through the feed port 2, and at the same time, the motor 33 is started. The output shaft of the motor 33 drives the rotating roller 31 and multiple dispersing rollers to rotate, thereby dispersing the ash and slag and preventing it from clumping. After the ash is broken up, the sealing plate 25 in the left discharge port 24 is opened, and the ash enters the waste heat recovery chamber 4 through the discharge port 24. Then, the hydraulic cylinder 7 on the left is started. The output end of the hydraulic cylinder 7 drives the L-shaped plate 8 to move to one side. At the same time, the L-shaped plate 8 moves to one side and drives the rack 11 to move, so that the rack 11 drives the gear 21 to rotate.

Simultaneously, rack 11 drives gear 12 to rotate, gear 12 drives rotating rod to rotate, rotating rod drives one of sprockets 29 to rotate, one of sprockets 29 drives another sprocket 29 to rotate via chain 1, causing rotating column 13 to drive bevel gear 14 to rotate, bevel gear 14 to drive bevel gear 25 to rotate, bevel gear 25 to drive telescopic rod 16 to rotate, telescopic rod 16 to drive bevel gear 317 to rotate, bevel gear 317 to drive bevel gear 418 to rotate, bevel gear 418 to drive rotating column 219 to rotate, rotating column 219 to drive turntable 9 to rotate, and turntable 9 to drive three adjusting rods 10 to rotate, realizing the continuous turning of ash and slag, ensuring that the ash and slag can make full and effective contact with the heat exchange manifold inside the L-shaped plate 8, thereby improving heat exchange efficiency; When the waste heat recovery operation is in progress on the left, the sealing plate 25 on the right will open accordingly, allowing the ash inside the dispersing chamber 6 to fall smoothly into the waste heat recovery chamber 4 below; this ensures the efficiency and continuity of the waste heat recovery process; when the waste heat collection work on the left is completed, the operator can open the valve 32 through the command of the control system, so that the ash will be transported along the preset path to the special collection chamber 5 for subsequent processing and disposal.
