Continuous garbage feeder capable of sealing fume and preventing clogging

Abstract

The invention relates to a component of a garbage incinerator, in particular to a continuous garbage feeder capable of sealing fume and preventing clogging in the garbage incinerator. The invention aims to provide a feeder which can avoid garbage bridge formation and fume leakage and spontaneous combustion of garbage exposed to heat all the time in operation. The invention has the technical scheme that the shape of the continuous garbage feeder is the combination of two prismatic tables; a hopper is in an inverted prismatic table shape with a bigger top and a smaller bottom, and the bottom end is provided with a blanking port; and the bottom end of the hopper is provided with a chute which is communicated with the blanking port of the hopper. The invention is characterized in that the chute is in a perfect prismatic table shape with a smaller top and a bigger bottom; and the inner cavity of the hopper is provided with a bridge breaker which can move up and down to eliminate the garbage bridge formation. The inner cavity of the chute is also provided with a rotatable baffle door, and the baffle door is driven by a driving device to realize the opening and the closing of a garbage channel.

Description

technical field [0001] The invention relates to a component of a garbage incinerator, in particular to a garbage continuous feeding device in the garbage incinerator with sealing flue gas and anti-clogging. Background technique [0002] In the waste incinerator, how to realize the sealing of the gas inside and outside the furnace while ensuring continuous and smooth feeding is the first step in determining whether the incinerator operates normally and stably. Therefore, the designed garbage feeding device must have the ability to temporarily store the garbage thrown in the grab bucket, use the garbage's own weight to continuously feed the incinerator, and use the thickness of the garbage itself to form a sealing layer to prevent air from leaking into the furnace and flue gas. Leakage. Whether the design of the garbage feeding device is reasonable or not is very important. [0003] In the Chinese patent application documents, the document with the patent application number ...

AI Technical Summary

Problems solved by technology

[0003] In the Chinese patent application documents, the document with the patent application number 01244847.8 discloses a feeding device for a domestic waste incinerator, in which the hopper is in the shape of a chamfered platform with a large upper part and a smaller lower part, and a discharge opening is formed at the bottom end. There is a chute connected to the discharge opening of the hopper; the bottom of the hopper of this structure is prone to garbage bridging phenomenon (garbage is blocked in the hopper and cannot fall), and after a period of time after the garbage bridging, the flue gas in the garbage incinerator will It will burst out and affect the normal operation of the incinerator

[0004] In the integrated furnace hopper structure of the domestic waste incinerator disclosed in the patent application No. 99229807.5, the hopper is a combination of two upper and lower prisms, which are also prone to garbage bridging and flue gas escape.
