Description

A kind of fine powder screening plate

Technical field

The utility model belongs to the cement manufacture plant technical field, relates to a kind of fine powder screening plate, is mainly used in the cement production process classifying equipoment to the screening of fine powder.

Background technology

At present, the classification to material in the process of cement processing of manufacture of cement industry is employed in installation punching sieve plate in the classifying equipoment.The existing punching sieve plate that uses is employed in the aperture of offering numerous circles on the sieve plate; Owing to had certain humidity, viscosity by the material of classification, and granularity is bigger, in the production process of reality; The inner normal phenomenon that card sieve plate sieve aperture occurs of classifying equipoment; Cause the powder material screening efficiency low, the raw meal particle size of separating is big, brings for the production of next procedure and has a strong impact on.Enterprise often is employed in the bigger improvement of carrying out technological parameter in the next procedure and adapts to the phenomenon that this raw meal particle size is big and size distribution is wide; A large amount of wastes of the energy have not only been caused; Increase the production cost of enterprise, also be not suitable for energy-saving and emission-reduction and modernized mass-produced requirement that country advocates.

Summary of the invention

The inventor is in the daily course of work; Find that existing manufacture of cement industry classifying equipoment exists above-mentioned defective in the screening process to material; Improve through constantly exploring; The utility model technical problem to be solved provides a kind ofly can efficiently sieve material, improves equipment operating efficiency, and simple in structure, practical a kind of fine powder screening plate.

For solving the problems of the technologies described above, the technical scheme that the utility model is taked is that the structure of this fine powder screening plate comprises the screening plate, and said screening plate is made up of one deck screening plate at least; When for multilayer screening plate; Linearly or stepped connection, said every layer of screening plate divides top screening plate and bottom screening plate between the screening plate of every adjacent layer, and every top screening plate and bottom are sieved plate and be the framework that trapezoidal shape constitutes by the 8-18 piece respectively and connect and compose; Between every framework, set firmly many gratings; Hole between adjacent grating forms sieve aperture, and each screen size is between 0.2mm-3mm, and bar is held in the palm in many of layings below every framework; Grating is fixed on the holder bar, and every layer of screening plate inclination angle with respect to the horizontal plane is between 20 °-80 °.

Said grating shape can be " V " font.

It is trapezoidal that said grating shape also can be.

Sieve aperture between said framework is the slotted hole that two ends that the fixed head upper edge Flow of Goods and Materials direction between framework is evenly laid are circular arc.

The utility model adopts a kind of fine powder screening plate that technique scheme designed, because every layer of screening plate has certain inclination angle, the screening plate is provided with sieve aperture; In actual use, powder material is easy to sieve by designing requirement, does not have the phenomenon of card sieve plate sieve aperture; Guarantee the normal operation of time road production process, reduced energy resource consumption, improved production efficiency; Reduced the enterprise production cost, and simple in structure, economical and practical.

The specific embodiment

Further specify the concrete structure that a kind of fine powder of the utility model sieves plate below in conjunction with accompanying drawing and embodiment.

Referring to Fig. 1 to Fig. 7, a kind of fine powder screening of the utility model plate structure comprises that sieving plate by one deck at least constitutes, and Fig. 7 is expressed as three layers of screening plate; Wherein between the screening plate of every adjacent layer linearly or stepped being connected and installed, every layer of screening plate divides top screening plate 7 and bottom screening plate 8, every top screening plate 7 is the trapezoidal framework that constitutes 1 by 8-18 piece top and the bottom respectively with bottom screening plate 8 and connects and composes; Use according to reality,, can establish 12 top and the bottom and be the framework formation that trapezoidal shape constitutes for easy to maintenance; Every 1 adjacent of framework interconnects; Set firmly many gratings 21 of every framework, grating 2 shapes can be " V " font or trapezoidal shape, and the hole that adjacent grating is 2 forms sieve aperture 3; Each sieve aperture 3 size between 0.2mm-3mm to guarantee sieving varigrained powder material by demands of different; To the pressure of grating, wherein, grating 2 is fixed on the holder bar 4 many holders of laying bar 4 in order to powder material on the support sieve plate below every framework 1; Every layer of screening plate inclination angle with respect to the horizontal plane shutoff do not occur with the normal screening of assurance powder material between 20 °-80 °, thereby guarantees the normal operation of next procedure.Referring to Fig. 1, the implementation of the sieve aperture 3 that the utility model framework is 1 is to set firmly many gratings 21 of framework, and the hole that adjacent grating is 2 forms sieve aperture 3; Referring to Fig. 3, the implementation of the sieve aperture 3 that the utility model framework is 1 also is circular arc 6 at the two ends that the fixed head 5 upper edge Flow of Goods and Materials directions of 1 of framework are evenly laid slotted hole forms sieve aperture 3.

Referring to Fig. 4; Fig. 4 representes to be installed in the structural representation in the grader when the utility model is one deck screening plate, during use, the utility model is installed in the grader; Powder material is under the effect of wind wheel 11; Sieve through top screening plate 7 and bottom 8 pairs of powder materials of screening plate, the powder material after being sized flows out grader along powder material passage 9 and gets into next process again, and the meal material after being sized flows out grader along meal material channel 10 to be waited to further process.

The utility model is on probation through trial-production, and effect is obvious, does not have the phenomenon of card sieve plate sieve aperture; Reach powder material screening on request, thereby guaranteed the normal operation of time road production process, reduced energy resource consumption; Improve production efficiency, reduced the enterprise production cost, and simple in structure; Economical and practical, will play central role for whole manufacture of cement industry energy-saving.
