A cement production preheater throwing type spreading device

Abstract

The invention relates to a material throwing type scattering device of a cement production preheater. The material throwing type scattering device comprises an air pipe (1), and a material scattering box (4) is arranged on the outer wall of one side of the air pipe and is provided with a feeding port (7), a discharging port (10) and a material poking hole (2). The material throwing type scattering device is characterized in that a material throwing wheel (8) is arranged in the material scattering box, a set of material scraping plates (9) are arranged on the outer circumference of the material throwing wheel, a buffering bin (6) and a material limiting port (5) are formed below the feeding port (7) in sequence, and the feeding port is communicated with the material scattering box through the buffering bin and the material limiting port. By means of the technical scheme, materials fed into the air pipe are scattered more evenly, the materials make full contact with hot air, the heating effect on the materials of the hot air is better, and the energy-saving effect of the device is obviously improved.

Description

Technical field: [0001] The invention relates to cement clinker production equipment, in particular to a throwing type material spreading device for a cement production preheater. Background technique: [0002] In the new dry process cement clinker process, the material will be added to the air duct of the preheater, and the waste heat will be used to preheat the material. Sprinkle evenly into the duct. [0003] The material spreading device is placed obliquely and straight down, with a material inlet and a material outlet, the material inlet is connected to the feeding facility, the material outlet is connected to the air duct, the waste heat in the air duct is upward, and the downward material and the upward hot air flow The collision breaks up and heats the material, the better the uniformity of the material sprinkled into the air duct, the more fully the contact between the material and the hot air, the better the heating effect of the hot air on the material, and the b...

AI Technical Summary

Problems solved by technology

However, when agglomerated or concentrated materials are encountered, this straight-through structure cannot achieve uniform material spreading, which seriously affects the preheating effect of the materials. Extensive searches have been conducted on the above problems, such as the Chinese invention patent "a high-efficiency dispersing powder Spreading device for shaped materials" (patent number: 201110446643.5) and invention patent "a combined adjustable spreading device" (patent number: 201410138435.2) and utility model patent "spreading device" (patent number: 201320273180.1), both of which are Use spreading board to block lumpy or concentrated materials, but it can only be improved but not eliminated
