Description

Technical Field

[0001] The utility model relates to the technical field of incinerator ash hoppers, in particular to a corrosion-resistant self-cleaning ash hopper in the flue of an incinerator. Background Technique

[0002] The ash hopper is installed directly below the grate of the waste incinerator. It is not only used for collecting and discharging the ash and slag leaked from the grate, but also serves as a circulation channel for the primary air. The primary air is the air sent into the air chamber at the bottom of the grate and is used for burning biomass and high-calorie domestic waste, providing oxygen for the combustion of the waste layer above the grate and the release of volatile components. Therefore, the evenness of the distribution of the primary air entering the furnace from the ash hopper will directly affect the quality of waste combustion. Only by achieving uniform distribution of the primary air can the waste burn evenly and sufficiently on the grate. A waste incinerator is a device for incinerating high-calorie domestic waste and the like.

[0003] Most of the edges of the ash hopper are inclined for the convenience of the fall of ash and slag, and its shape is generally funnel-shaped. After long-term use of the ash hopper, more ash and slag are likely to remain on its inner wall. These ash and slag generally adhere to the inner wall and are difficult to fall off. This easily leads to a reduction in the practical effect of the ash hopper. And as more and more residual ash and slag accumulate, the ash hopper will become unusable and needs to be disassembled for cleaning, which will undoubtedly affect the normal use of the incinerator. Therefore, it is necessary to design a self-cleaning incinerator ash hopper. Summary of the Invention

[0004] The embodiment of the utility model provides a corrosion-resistant self-cleaning ash hopper in the flue of an incinerator to solve the problems in the background technique.

[0005] The embodiment of the utility model adopts the following technical solution: A corrosion-resistant self-cleaning ash hopper in the flue of an incinerator, including an ash hopper.

A cleaning rod is connected between the two rotating members. The cleaning rod contacts the inner wall of the ash hopper, and the residual ash and slag on the inner wall of the ash hopper can be scraped off through the cleaning rod. It solves the problem that after long-term use of the ash hopper in the prior art, more and more ash and slag remain on its inner wall, resulting in affecting the normal use of the ash hopper.

[0006] Further, cross plates are provided on both the top fixing frame and the bottom fixing frame, and the two cross plates are vertically corresponding up and down.

The protective frame can play a good protective role for the double-shaft motor and the driving rods, preventing ash and slag from falling into the double-shaft motor. The double-shaft motor can drive the two driving rods to rotate to make the rotating member operate.

[0008] Further, rotating blocks and connecting plates are provided at the upper and lower ends of the protective frame. The two connecting plates are respectively fixedly connected to the bottom fixing frame and the top fixing frame. The rotating blocks are located between the protective frame and the connecting plates.

[0009] Further, each group of rotating members includes a telescopic connecting rod and a sliding connection frame. The sliding connection frame is slidably installed in a limiting groove. One end of the telescopic connecting rod is connected to the sliding connection frame, the other end of the telescopic connecting rod is connected to the rotating block, and the sliding connection frame is connected to the cleaning rod. The rotating member is used to drive the cleaning rod to move on the inner wall of the ash hopper.

[0010] Further, a return spring is provided in the telescopic connecting rod, and the telescopic connecting rod can be reset after moving through the return spring. The return spring can make the telescopic connecting rod stretch more conveniently.
