Abstract
The utility model discloses a preliminary cleaning sieve. The preliminary cleaning sieve comprises a housing, wherein a feeding hole, an oversize product outlet and a screening outlet which are arranged on the housing, wherein a rotary screen drum is arranged inside the housing; the section of the rotary screen drum is in the form of an equilateral polygon. According to the preliminary cleaning sieve, the section of the rotary screen drum is in the form of a regular octagon; the screen drum comprises a screen drum framework with a regular octagon shaped section and eight rectangular sieves which are fixed on the framework; sieve frames which are matched with the rectangular drum surface of the sieve drum framework are arranged around the rectangular sieves; and the sieve frames are fixed on the sieve drum framework by bolts. With the adoption of the preliminary cleaning sieve, the materials can be turned over on a screen in a three-dimensional manner during working; and the the preliminary cleaning sieve is high in sieving efficiency and good in filter rate.
Description
Technical field
The utility model relates to a kind of screening plant, especially a kind of receiving sieve.
Background technology
Receiving sieve is a kind of screening installation commonly used in grain, the feed processing enterprise production process, is used for raw material is screened.The screen drum of receiving sieve mostly is the screen drum of circular cross-section in the prior art, and the material during this circular screen drum work in the screen drum slides at screen cloth all the time reposefully, and material is longer in the screen surface time of staying, screens not thoroughly, and operating efficiency is lower.
The utility model content
The technical problem that utility model will solve: a kind of receiving sieve is provided, can makes material three-dimensional rolling on screen cloth during this receiving sieve work, screening operation efficient is high, and it is good to leach rate.
The technical scheme that the technical solution problem is taked: a kind of receiving sieve, comprise housing, be provided with charging aperture, oversize outlet, screenings outlet at housing, be provided with the rotation screen drum in enclosure interior, the cross section of described rotation screen drum is regular polygon.
As improvement of the present utility model: the cross section of described rotation screen drum is octagon.
As further improvement of the utility model: described screen drum is that the screen drum framework of octagon and eight rectangular mesh screens being fixed on the framework consist of by the cross section.
Further improve as of the present utility model: be provided with the screen frame that matches with screen drum framework rectangular cylinder face around rectangular mesh screen, screen frame is fixed by screws on the screen drum framework again.
Beneficial effect: receiving sieve of the present utility model, owing to adopted described receiving sieve to comprise housing, be provided with charging aperture at housing, the oversize outlet, the screenings outlet, be provided with the rotation screen drum in enclosure interior, the cross section of described screen drum is the technical scheme of octagon, material when having overcome the screen drum work of circular cross-section in the prior art in the screen drum slides at screen cloth all the time reposefully, cause material longer in the screen surface time of staying, screen not thorough, the shortcoming that operating efficiency is lower makes material three-dimensional rolling on screen cloth, and screenings is separated rapidly with oversize, improved the operating efficiency of screening, and the rate that leaches that can the Effective Raise screening; Because to have adopted described screen drum be the screen drum framework of octagon by the cross section and be fixed on eight technical characterictics that rectangular mesh screen consists of on the framework, having overcome cylindrical shape screen drum of the prior art is surrounded by a screen cloth integral body, in case the shortcoming that the screen cloth local damage must integral replacing, realized that eight rectangular mesh screens that consist of screen drum can change separately, reduced operation and the maintenance cost of equipment; Owing to adopted and around rectangular mesh screen, be provided with the screen frame that matches with screen drum framework rectangular cylinder face, screen frame is fixed by screws in the technical characterictic on the screen drum framework, realize Quick overhaul and the replacing of screen cloth, shortened the maintenance time of equipment, improved the production efficiency of equipment.
