Abstract

The utility model relates to a fluidization micro-boiling drier, which is mainly composed of a fluidization boiling furnace and a fluidization micro-boiling vibration drier. The spring link and the drive link of the drier are both arranged on the outside of a casing. An ash collecting bucket and a secondary dust collector are additionally arranged on the utility model. The driving of the complete machine is steady and reliable. The drier can be used in cement mill for drying raw material of clay soil and slag, etc. The heat efficiency arrives 75% to 85%, and the dust-collecting efficiency arrives 99%.

Description

The little boiled bed dryer of fluidization

The utility model is to belong to the component invention of flue gas fluidized bed furnace and vibration drying machine and the improvement of structure thereof.This machine is applied to the oven dry of raw materials such as cement industry clay, slag, in order to the calcining of cement kiln.

The dryer assembly of prior art cement raw material has following several:

1. hand burns formula hot-blast stove and the assembly of swinging rotary drum dryer;

2. high-temperature flue gas stove and the assembly of swinging rotary drum dryer;

3. high-temperature flue gas stove and the assembly of vibration drying machine.

Above-mentioned three kinds of assembly are reflection technical development processes, but existing high-temperature flue gas stove has two smoke chambers of U type, and the hot-fluid resistance is big, hot heterodyne, all in casing, parts are very fragile under the high temperature running for the drive disk assembly of vibration drying machine again, often be out of order, so dryer efficient is not high.

The purpose of this utility model is to adopt fluidized bed furnace and the assembly of vibration drying machine, with the raising thermal efficiency, and vibration drying machine driving member is done significant improvement.

Content of the present utility model is:

The little boiled bed dryer general construction of fluidization as shown in Figure 1, having 17 parts forms, it is mainly linked to each other with electric and magnetic oscillation feeding machine 2 by the wet feed storehouse 1 at top, divide into belt weigher 3, the tremie pipe 6 of scale and the exhanst gas outlet of fluidization fluidized bed furnace 4 all link to each other with vibration drying machine 7, blast pipe 13 1 ends are connected with vibration drying machine 7 tops, the other end and one-level cyclone type dust-precipitator 14 join, material conveyor 11 all joins with hopper 10 and one-level cyclone type dust-precipitator 14, and feature of the present utility model is:

(1) this machine adopts fluidization fluidized bed furnace 4 to be connected assembly with vibration drying machine 7;

(2) this fluidization fluidized bed furnace 4 is that the improvement of high-temperature flue gas stove is made up of combustion chamber and smoke chamber two parts, and is simple in structure;

(3) this vibration dryer 7 as shown in Figure 4, its spring link 20, kinematic link 23 all is assembled on the main shaft 25 that extends to outside the body fuselage 19, buncher 21 also is contained in outside the casing, the material of the comb bed 22 in the casing adopts heat resisting steel, its mounted angle is controlled at the 9.5-13 degree, makes the bed operation in the best condition of combing;

(4) body of vibration drying machine 7 is divided into 6 flue-dust retainers 8, has all adorned two-door turnover panel lock wind unloading valve 9 in each bucket, leaks out to reduce complete machine, and each end of struggling against all joins with material conveyor 11;

(5) this machine has been set up the secondary resistive connection and is revealed vertical electrostatic precipitator 15 or resistive connection and reveal bag filter 16 (selected according to using field condition), to improve dust-collecting efficiency, the secondary dust-precipitator is suitable for reading to link to each other with exhaust blower 17, middle mouthful links to each other with one-level cyclone type dust-precipitator 14, and end opening links to each other with material conveyor 11.

Advantage of the present utility model:

1. the best assembly of thermal source and dryer, the thermal efficiency that makes dryer system are brought up to about 75--85% from 40%, and can utilize lower calorific value fuel and industrial residues such as colm, gangue, flyash;

2. after increasing the secondary dust-precipitator, its dust-collecting efficiency is about 99%;

3. the dryer transmission is stable, reliable, and assurance equipment is running rate under hot state.
