Background technology
In industry production process such as feed, flour, food, chemical industry, sugaring, mining, papermaking, sizing screening equipment is a kind of main equipment, is mainly used in the screening and the classification of granular material or particulate material.Common a kind of screening machine, be included in the screen drum of horizontal setting in the casing, screen drum is made up of screen section that is linked in sequence and impurity removal section, the casing of screen section downside is provided with discharging opening, the casing of impurity removal section downside is provided with impurity outlet, be provided with rotor in the screen drum, casing one end is provided with feeding-passage, rotor shaft one end passes feeding-passage and is connected with transmission mechanism, rotor shaft section in the feeding-passage is provided with projectile, and stretches out some struts to inboard wall of riddle drum radially on the corresponding rotor shaft of screen section, and the strut end is fixed with the connecting rod parallel with inboard wall of riddle drum, connecting rod is provided with and re-packs, and fixedlys connected between screen drum and the casing.The screening machine of this structure is when work, rotor rotation, screen drum maintains static, projectile advances the material in the feeding-passage to screen drum, re-pack simultaneously the material of caking is broken up, in the strike process, tiny material passes the sieve aperture on the screen drum, leave from discharging opening, bigger material leaves from impurity outlet in progradation; Because material is crossed the mainly side on the lower side in screen drum of compass screen surface, the process of sieving small particles material is close to compass screen surface all the time, causes the obstruction of compass screen surface easily, thereby has a strong impact on screening effect.
The utility model content
The utility model provides a kind of fine classification sieve, can improve the screening efficiency of classifying screen by the sieving rate that increases the compass screen surface particulate material.
For achieving the above object, the fine classification sieve that the utility model order provides, be included in the screen drum of horizontal setting in the casing, screen drum is made up of screen section that is linked in sequence and impurity removal section, the casing of screen section downside is provided with discharging opening, the casing of impurity removal section downside is provided with impurity outlet, be provided with rotor in the screen drum, casing one end is provided with feeding-passage, rotor shaft one end passes feeding-passage and is connected with transmission mechanism, rotor shaft section in the feeding-passage is provided with projectile, with stretch out some struts to inboard wall of riddle drum radially on the corresponding rotor shaft of screen section, the strut end is fixed with the connecting rod parallel with inboard wall of riddle drum, connecting rod is provided with some re-packing, be provided with wear-resisting supporting member between described screen drum and the casing, an end of the impurity removal section of screen drum and the rotating shaft of drive motors are in transmission connection.
When work, drive motors drives screen drum and rotates, and transmission mechanism drives between rotor and the screen drum and makes backward rotation, can increase the chance that sieve aperture contacts with material, material can not piled up in the screen drum bottom and the obstruction sieve aperture, make less than the material of sieve aperture is easier and sieve, improved the sieving rate of material.The utility model can be used for tiny powder classification, with improve the powder particle all once, can be applicable to industries such as feed, flour, food, chemical industry, sugaring, mining, papermaking.
Can make things convenient for for after making material stop up sieve aperture, cleaning in time, can with casing relative fixed blowing device, the nozzle of blowing device is arranged on the casing inboard of screen drum top or side.In case of necessity, compressed air is oppositely blown over sieve aperture, can blow the sieve aperture that stops up logical by nozzle.
For making the utility model can adapt to the stock grading of different impurity contents, described re-packing comprises two planes of at right angles intersecting, and one of them plane is fixed on the connecting rod through screw.Unclamp screw, can regulate the angle of cut of another plane and rotor shaft, when rotor rotation, this plane can advance material to the impurity removal section, be adjusted to different angles, can obtain different fltting speeds, so that corresponding with the impurity content in the material, to mix more for a long time when containing, fltting speed is suitable quicker, otherwise, then should be slow.
Described projectile can be helical blade or the blade for being provided with at interval, also can be the mechanism that other mechanisms can impel material to move in screen drum.This structure makes material enter in the sieve nest and can unimpededly enter in the screen drum from charging aperture.
