Abstract
The utility model relates to a cement machine, and discloses an anti-blockage roller mill for air ducts. The anti-blockage roller mill comprises an upper mill body and a lower base, wherein the mill body comprises a bearing seat, a millstone and an outer cover; the lower part of the outer cover is provided with a material scraping chamber, the upper part thereof is provided with an air ring; a material scraping plate is arranged in the material scraping chamber; the outer surface of the lower part of the outer cover is an inward inclined surface; and an air inlet pipe is arranged on the inclined surface of the outer cover. The anti-blockage roller mill is characterized in that a guiding plate is arranged on the upper edge of an air outlet on the air inlet pipe. The anti-blockage roller mill solves the problem that when the existing roller mill works, the air inlet pipe is easily blocked by material, thus increasing the ventilation resistance and influencing smooth air flow inside the roller mill, and is mainly applied to processing of cement.
Description
(1) technical field: the utility model relates to cement machinery equipment, especially a kind of air channel block-proof type Vertical Mill that is used to process clinker.
(2) background technology: the Vertical Mill that is used for clinker processing at present mainly is made up of last mill body and lower bottom base two parts, referring to Fig. 1, described mill body includes supporting base 8, mill 2 and outer casing 3, outer casing 3 bottoms are scraper chamber 6, vane 1 is arranged at top, be provided with material scraping plate 7 in the scraper chamber 6, and the lower external face of outer casing 3 is inside inclined plane, on the inclined plane of outer casing 3, be provided with blast pipe 4, this structure, the air channel air intake flat segments of blast pipe is longer, and because the position of blast pipe 4 and outer casing 3 relation (outer casing inclination, air inlet duct is horizontally disposed with), just in time some can drop on the exit flat segments of blast pipe 4 material 5 that throws away during mill 2 work, forms buildup, when buildup is too much, obviously can reduce the draught area in air channel, increase flowing resistance, have influence on the air velocity distribution of Vertical Mill inside, finally influence material crudy and output.
(3) summary of the invention: material stopped up the air channel easily when the purpose of this utility model will solve existing Vertical Mill work exactly, increased flowing resistance, influenced the problem in Vertical Mill internal gas flow flow field, and a kind of air channel block-proof type Vertical Mill is provided.。
Concrete scheme of the present utility model is: improve at existing Vertical Mill, it has the mill of going up body and lower bottom base two parts are formed, described mill body includes supporting base, mill and outer casing, the outer casing bottom is the scraper chamber, vane is arranged at top, and scraper is provided with material scraping plate in the chamber, and the lower external face of outer casing is inside inclined plane, be provided with blast pipe on the inclined plane of outer casing, particularly: the air outlet upper edge at blast pipe is provided with stock guide.
For making things convenient for guide, 20 °～30 ° layouts of the inclination of stock guide described in the utility model.
For guaranteeing that material all falls into the scraper chamber, can not pile up in the exit of blast pipe, the outer of stock guide described in the utility model is concordant with the air outlet lower edge of blast pipe or extension arranged.
The utility model is simple and practical, owing to installed stock guide additional in the air outlet upper edge in inlet pipe road, can guarantee that material that mill falls along the limit just in time all falls into the scraper chamber along the direction of wind deflector and scrapes by material scraping plate, can not form buildup in the blast pipe flat segments, it is smooth and easy to guarantee to ventilate, and guarantees Vertical Mill internal gas flow flow field working stability.Final material crudy and the output that guarantees Vertical Mill.
(4) description of drawings:
Fig. 1 is the half sectional view of existing Vertical Mill;
Fig. 2 is a half sectional view of the present utility model.
Among the figure: 1-vane, 2-mill, 3-outer casing, 4-blast pipe, 5-material, 6-scraper chamber, 7-material scraping plate, 8-supporting base, 9-lower bottom base, 10-stock guide.
(5) specific embodiment:
Referring to Fig. 2, the utlity model has the basic structure of common Vertical Mill, it comprises mill body and lower bottom base 9 two parts composition, described mill body includes supporting base 8, mill 2 and outer casing 3, and outer casing 3 bottoms are scraper chamber 6, and vane 1 is arranged at top, be provided with material scraping plate 7 in the scraper chamber 6, and the lower external face of outer casing 3 is inside inclined plane, is provided with blast pipe 4 on the inclined plane of outer casing 3, and particularly: the air outlet upper edge at blast pipe 4 is provided with stock guide 10.
And 20 °～30 ° layouts of these stock guide 10 inclinations; The outer of stock guide 10 is concordant with the air outlet lower edge of blast pipe 4 or certain extension arranged.
Claims (3)
1. air channel block-proof type Vertical Mill, mainly form by last mill body and lower bottom base two parts, described mill body includes supporting base, mill and outer casing, the outer casing bottom is the scraper chamber, vane is arranged at top, and scraper is provided with material scraping plate in the chamber, and the lower external face of outer casing is inside inclined plane, be provided with blast pipe on the inclined plane of outer casing, it is characterized in that: the air outlet upper edge at blast pipe is provided with stock guide.
2. air channel according to claim 1 block-proof type Vertical Mill is characterized in that: 20 °～30 ° layouts of described stock guide inclination.
3. air channel according to claim 1 block-proof type Vertical Mill is characterized in that: the outer of described stock guide is concordant with the air outlet lower edge of blast pipe or extension arranged.
