Embodiment Construction

[0026] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0027] In the present invention, the bottom helical blade rotates and pushes the material to accumulate at the optical axis without the blade to form a ring-shaped material sealing layer for sealing, so as to isolate the gas inside and outside the kiln. A kind of screw conveyer of the present invention, specifically comprises the steps:

[0028] The output shaft of the reduction motor 8 rotates with the torque limiting coupling 7 and the shaftless screw blade 4. When the ash and slag in the kiln fall into the U-shaped cavity of the screw conveyor, the shaftless rotating blade 4 sends the material to the bladeless It is located in the annular cavity, and the material is continuously supplied from...

Abstract

The invention relates to a screw conveyer. The screw conveyer is conveying equipment which cools solid materials such as ash and slag produced in a rotary kiln, accumulates and extrudes the materialsfor sealing and isolating smoke, gas and dust of an outlet in the rotary kiln, and prevents outside air from entering the rotary kiln. Lower screw blades rotate to push the materials, so that the materials are accumulated on a plain shaft without blades to form an annular material seal layer for sealing and isolating the gases inside and outside the kiln.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment and conveying equipment, in particular to a screw conveyor. Background technique [0002] The temperature of ash and slag produced by the third-generation rotary kiln for domestic waste recycling is high, and the gas in the furnace generally has harmful components, and it is in a continuous output state. Existing slag cooling devices include ash unloading valve plus slag cooling machine, double flap valve plus slag cooling machine or double gate (plug) plate valve plus slag cooling machine. Due to the high temperature of the output, the seals of all the above valves can only be metal seals, and the output will also cause wear and sticking of the valves, and the existing technology of all valves is basically switched by mechanical action: the first valve opening - Material falls - first valve closes - second valve opens - material falls to the slag cooler - slag cooler cools the outp...
