Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of incinerators, in particular to a feed fire damper for an incinerator. Background Art
[0002] A garbage incinerator is a device for burning and treating garbage. The garbage burns in the furnace and turns into waste gas which enters the secondary combustion chamber. It is completely burned under the forced combustion of the burner and then enters the spray dust collector. After dust removal, it is discharged into the atmosphere through the chimney.
[0003] Patent publication number CN212390378U discloses a fire damper for incinerators. This device utilizes a rotatable gate that blocks the inlet of the furnace body and is secured by a lever. The gate can be rotated downward to open and pulled upward to close using a steel wire rope. However, this fire damper, like existing incinerator gates, suffers from the following drawbacks: Because it utilizes a single gate, the moment the gate is opened, high temperatures and flames from within the furnace body can easily burst through the gate opening. This results in extremely high temperatures during charging, making loading dangerous. Therefore, further improvements are needed. Utility Model Content

[0006] Furthermore, the bottom plate is fixed to the outer wall of the furnace body by welding, and the side of the feed tube with a lower height is connected to the feed port of the furnace body.
[0007] Furthermore, the lifting assembly includes a motor fixed to the top of the gantry, a screw rod is fixed to the bottom driving end of the motor, a threaded groove is opened in the middle of the inner gate, and the screw rod is rotatably connected to the threaded groove.
[0008] Furthermore, the fixing assembly includes a handle fixed to the surface of the outer gate, a slide groove is provided on the top of the handle, a spring is fixed on the bottom wall of the slide groove, and a clamping rod is fixed on the top of the spring, and the top of the clamping rod is clamped into the inside of the clamping hole.
[0009] Furthermore, a strip opening is formed on a side of the slide groove away from the outer gate, and a shift rod is fixed on a side of the clamping rod close to the strip opening. The shift rod passes through the strip opening and is slidably connected to the strip opening.
[0010] Furthermore, the pushing assembly includes a push rod passing through the perforation of the outer gate, the push rod is slidingly connected to the perforation, a push plate is fixed to one end of the push rod located inside the feed barrel, and a handle is fixed to one end of the push rod located outside the feed barrel.
[0011] Beneficial effects of the utility model:
[0012] 1. When the utility model is in use, the incinerator is provided with a feed fire damper, a bottom plate, a feed barrel, an inner gate, an outer gate, a gantry and a lifting assembly. When loading, the outer gate can be opened first, and the inner gate is closed at this time. After the material enters the feed barrel, the outer gate is closed, and then the inner gate is opened, so that the material enters the furnace body from the feed port of the furnace body along the feed barrel. By setting two alternately opened gates, the high temperature inside the furnace body is prevented from gushing out from the feed port during loading, and loading is safer and more convenient.
[0013] 2. When the utility model is in use, the incinerator feed fire damper is provided with a pushing assembly, through which the material in the upper barrel can be pushed into the furnace body to prevent the material from staying in the upper barrel. BRIEF DESCRIPTION OF THE DRAWINGS
