Abstract
The utility model discloses the blanking baffle arrangement structure of a kind of coal mill, it is provided with raw coal in coal pulverizer spiral import department to enter to grind scraper-trough conveyer, raw coal enters to grind in scraper-trough conveyer to be provided with four pieces of blanking deflectors, four pieces of blanking deflectors are skewed equidistant layout, and be staggeredly arranged with stepped-style, angle of inclination and blanking deflector and vertical plane angle are 43 °, every block blanking deflector length 350mm.The utility model can improve deflector unloading performance, when effectively preventing material moisture larger water conservancy diversion harden hang blocking generation, stop to amass coal phenomenon into mill hot-air mouth place, prevent from amassing coal spontaneous combustion herein.
Description
Technical field
The utility model relates to the tubular type coal pulverizer of cement producing line.
Background technology
Current cement producing line the fed version of tubular type coal pulverizer, as Fig. 1 shows, all be provided with raw coal at coal pulverizer spiral import 1 place to enter to grind scraper-trough conveyer 2, raw coal enters to grind in scraper-trough conveyer 2 to be provided with three pieces of blanking deflectors 4, three pieces of blanking deflectors 4 are arranged in skewed stepped-style, deflector and vertical direction arrange that angle a value is 57 °, every block blanking deflector 4 length b=280mm; And enter to grind scraper-trough conveyer 2 at raw coal and be below provided with thermal chimney 3.Find in actual motion, because deflector above-mentioned parameter is unreasonable, when raw coal moisture is bigger than normal, it is not smooth that material walked by raw material, can overflow between deflector ladder, be deposited on and form long-pending coal 5 into mill hot-air mouth place, there is spontaneous combustion hidden danger in long-pending coal 5, constitutes a threat in high temperature environments to system safety operation.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model improves the blanking baffle arrangement structure that existing coal grinds, and designs the blanking baffle arrangement structure of a kind of new coal mill.
A kind of blanking baffle arrangement structure of coal mill, it is characterized in that, it is provided with raw coal in coal pulverizer spiral import department to enter to grind scraper-trough conveyer, raw coal enters to grind in scraper-trough conveyer to be provided with four pieces of blanking deflectors, four pieces of blanking deflectors are skewed equidistant layout, and be staggeredly arranged with stepped-style, angle of inclination and blanking deflector and vertical plane angle are 43 °, every block blanking deflector length 350mm.
The utility model has the advantages that: owing to increasing blanking deflector length, deflector quantity is increased to four pieces by former three pieces simultaneously, deflector is encrypted, make the gap shrinks between blanking deflector, compressed material refluence space, effective prevention material flows backwards, and deflector and vertical direction angle degree are reduced to 43 ° by 57 °, improve deflector unloading performance, when effectively preventing material moisture larger water conservancy diversion harden hang blocking generation, stop to amass coal phenomenon into mill hot-air mouth place, prevent from amassing coal spontaneous combustion herein.
Accompanying drawing explanation
Fig. 1 is existing blanking baffle arrangement structural representation;
Fig. 2 is the utility model blanking baffle arrangement structural representation.
Marginal data, the import of 1-coal pulverizer spiral, 2-raw coal enters to grind scraper-trough conveyer, 3-thermal chimney, 4-blanking deflector.
B represents blanking deflector length, and α represents angle of inclination.
Detailed description of the invention
Fig. 1 is existing blanking baffle arrangement structural representation, and its structure describes in detail in the introduction, no longer repeats at this.
Fig. 2 is the utility model blanking baffle arrangement structure chart, as can be seen from the figure: it is provided with raw coal at coal pulverizer spiral import 1 place to enter to grind scraper-trough conveyer 2, raw coal enters to grind in scraper-trough conveyer 2 to be provided with four pieces of blanking deflectors 4, four pieces of blanking deflectors 4 are in skewed equidistant layout, and be staggeredly arranged with stepped-style, tilt angle alpha and blanking deflector 4 are 43 ° with vertical plane angle, every block blanking deflector 4 length b=350mm.
