Abstract
The utility model provides a kind of air-cooled roll, comprises the diameter of axle at roll body and roll body two ends, and described roll body and the diameter of axle are hollow; It is characterized in that being fixedly installed spirality guide vane or axial fan blade in roll body cavity.Described diameter of axle hollow end sections in roll body is preferably horn-like.The number that spirality guide vane or axial fan blade is set at roll body cavity can be one also can be for multiple.Described air-cooled roll can significantly improve the wind speed in roll, effectively reduces roll temperature in use, improves the quality of its flour of producing.
Description
Technical field
The utility model relates to a kind of roll, is specifically related to a kind of air-cooled roll.
Background technology
The roll particularly using at abrasive dust machinery in the market, due to the accumulation of the heat that in use produced, roller temperature raises, and causes produced flour quality to decline.Some enterprises adopt water-cooling pattern to solve, but due to problems such as sealings, are not accepted by market; The hollow self-wind cooling grinding roller patent that my company's notification number is CN201880560U, disclose at the hollow diameter of axle inwall of grinding roller and be processed with guiding gutter, the grinding roller that relies on guiding gutter to drive air that heat is discharged, but in actual application, roll temperature declines not obvious, and this patent is not promoted enforcement.
Summary of the invention
The utility model, for solving the existing problem of prior art, provides a kind of air-cooled roll, and described air-cooled roll can significantly improve the wind speed in roll, effectively reduces roll temperature in use, improves the quality of its flour of producing.
Described air-cooled roll comprises the diameter of axle at roll body and roll body two ends, and described roll body and the diameter of axle are hollow; It is characterized in that being fixedly installed spirality guide vane or axial fan blade in roll body cavity.
Described diameter of axle hollow end sections in roll body is preferably horn-like.
According to the different model of roll, the number that spirality guide vane or axial fan blade is set at roll body cavity can be one also can be for multiple.
Air-cooled roll described in the utility model is in the time of work, described spirality guide vane or axial fan blade rotate with roll, the air of roll inside is under the effect of blade, air enters from the hollow diameter of axle of one end, the horn-like end of the diameter of axle is by airflow concentration, discharge from the hollow diameter of axle of the other end fast, roll body internal cavities rapid flow air like this, the heat that roll in use can be produced is taken away, effectively reduce roll temperature in use, improve the quality of the flour of producing.
Air-cooled roll described in the utility model temperature in use than the roller temperature of current non-the technical program low 12 DEG C ~ 15 DEG C, the utility model is simple in structure, cost increase is only between 1% ~ 2%, market acceptance level is high, has promotional value.
Brief description of the drawings
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is the utility model embodiment 2 structural representations.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model detailed description of the invention is described further:
Embodiment 1
As shown in Figure 1, air-cooled roll described in the utility model comprises the diameter of axle 2 at roll body 1 and roll body two ends, and described roll body 1 and the diameter of axle 2 are hollow; It is characterized in that being fixedly installed spirality guide vane 3 at roll body inner chamber.
A spirality guide vane 3 is set in the roll body cavity of described air-cooled roll.
Embodiment 2
