Description

Angle-adjustable cylindrical screen

Technical Field

The utility model relates to the technical field of mineral screening equipment, in particular to a cylindrical screen with an adjustable angle.

Background

Minerals are heavily contaminated during their collection: such as large-particle soil blocks, broken stones, roots, stems and leaves of various plants, and even large-particle impurities such as glass metal substances are sometimes mixed; but also fine impurities such as sand, dust, paper dust and the like. These impurities affect the storage and processing of the raw materials to varying degrees, affect the purity and quality of the finished product, and even cause a certain amount of damage to the equipment, so that they need to be screened out of the mineral pile in time.

The cylinder screen used in the previous screening process only has one screen body, only screens fine gravel or large rocks, and if another screening is needed, the cylinder screen with another aperture size needs to be used for another screening.

The drum sieve probably can often screen different mineral, but needs to adjust the inclination of drum sieve according to the difference of factors such as mineral particle size for mineral dwell time in the filter screen section of thick bamboo is longer, screens more meticulously, and the drum sieve of prior art is generally all fixed angle, and the operation of angle of adjustment is comparatively loaded down with trivial details. In the screening process of the cylindrical screen, if the inclination of the cylindrical screen is too small, the discharging of the cylindrical screen is difficult, and the crops move slowly; if the inclination of the cylindrical screen is too large, the discharging of the drum screen is too fast, and the crop moves too fast, so that the screening effect of the drum screen is poor.

If the cylindrical screen can complete two screening processes at one time, at least one process can be saved, and manpower and material resources are saved; if the angle of the cylindrical screen can be simply, conveniently and quickly adjusted, the cylindrical screen can be used back and forth in screening operation of different minerals.

Such structural design lets interior screen frame can stably follow outer screen frame and rotate, and can reserve out more spaces screening material, supplies the material to discharge.

Further, the bottom of the supporting component is provided with an anti-skid shock pad. Due to the structural design, the equipment can be more stable during feeding and blanking.

Further limit, interior screen frame and outer screen frame all are provided with a plurality of sieve meshes, and the sieve mesh diameter of interior screen frame is bigger than the sieve mesh diameter of outer screen frame. Due to the structural design, the granular materials with larger sizes can be screened into the outer screen body, and the granular materials with small sizes can be screened out by the outer screen body.

By adopting the technical scheme of the utility model, the utility model has the following beneficial effects:

the utility model relates to a cylinder screen capable of adjusting the angle, which is characterized in that most of the prior cylinder screens are generally fixed angles or the operation of adjusting the angle is complicated, while the cylinder screens can frequently screen different types of minerals in practical use, but the inclination angle of the cylinder screens can be adjusted according to different requirements of factors such as the size of mineral particles; the cylinder screen used in the previous screening process only has one layer of screen body, small-particle impurities such as sand and gravel are removed after screening, but larger or heavier impurities such as soil blocks, broken stones, roots, stems and leaves of various plants and the like often enter a collection box along with minerals, and another cylinder screen is needed to be used for screening again. Therefore, the utility model combines the angle-adjustable cylindrical screen equipment and the double-layer screening equipment to achieve the effects that two screening processes are simultaneously completed and the angle can be simply, conveniently and quickly adjusted.
