Abstract
The utility model provides a drum screen which comprises a rack, and guard plates, a drum, a feeding port and a discharging port, which are arranged on the rack. The drum screen is characterized in that the center of the drum is provided with a central shaft, the central shaft is arranged in bearing pedestals at the two ends of the rack, one end of the central shaft is connected with a rotating shaft of a speed reducer, the speed reducer is driven by a motor, the drum is a round drum which is laterally horizontally arranged, different numbers of sieves are fixed on the circumference of the drum by sections, the number of the sieves gradually increases from the feeding port, the upper part of the rack is open and sealed by the guard plates in four directions, the feeding port is arranged at the end of the central shaft of the drum screen, which is connected with the motor, and the discharging port is arranged at the lower part of the drum screen. When the drum screen is used, materials enter the drum screen from the feeding port, the drum screen rotates, the materials roll and are screened by grain sizes through the sieves, and a sizing screening purpose is achieved. The drum screen has the characteristics of simple and reliable structure, convenience in use, not easily blocked sieve holes and high screening efficiency.
Description
Technical field
The utility model relates to a kind of rotary screen.
Background technology
In the fertilizer production process, fertiliser granulates with different sizes, sieving according to technical standard is one of fertilizer production process, usually use flat vibratory sieve to carry out particle size separation in the existing technology, stop up sieve aperture but particle in use often occurs, cause sieving area to reduce, reduced screening efficiency, often need the labor cleaning, affect production efficiency, increased workload.
Summary of the invention:
The purpose that the utility model relates to is the problem that exists in order to solve prior art, provides a kind of simple and reliable for structure, easy to use, non clogging screen hole, the rotary screen that screening efficiency is high.
The utility model is realized by following technical scheme: a kind of rotary screen, comprise the backplate on frame and the frame, cylinder, charging aperture, feed opening, it is characterized in that there is a central shaft in described centre of the drum, central shaft is installed in the bearing block at frame two ends, one end is connected with the reductor rotating shaft, reductor is by driven by motor, cylinder is the circular drum that a transverse horizontal is installed, the segmentation of cylinder periphery is the screen cloth of different meshes fixedly, from charging aperture backward sieve number increase gradually, described upper rack is out shape, seals with backplate all around, an end that connects motor at the rotary screen central shaft is provided with charging aperture, and the rotary screen bottom is provided with feed opening; The utility model course of work is that material enters rotary screen from charging aperture, and the rotary screen rotation is rolled material and realized by sizing by screen cloth, reaches the purpose of gradation sizing, have simple and reliable for structure, easy to use, non clogging screen hole, the characteristics that screening efficiency is high.
