Abstract
The utility model provides a powder sieving device in a cement clinker mill. The powder sieving device comprises sieving pieces and a disc-shaped carrier for the installation of the sieving pieces, wherein the sieving pieces are formed into fan-shaped sieving pieces, and are installed on the carrier through fixing screws (3); multiple fan-shaped sieving pieces (5) form a disc-shaped sieving plate; sieving holes (4) in each fan-shaped sieving piece (5) are shaped like a long strip, and are longitudinally arranged along the radial direction of a fan shape. According to the powder sieving device in the cement clinker mill, as the sieving holes are in the shape of the long strip respectively, and are perpendicular to the direction of a linear speed in the rotation of the sieving plate, the passing performance of sieved powder is effectively improved, and the occurrence rate of blockage accidents is decreased; therefore the energy consumption is decreased, and the efficiency is improved.
Description
Technical field
The utility model relates to a kind of clinker fluffing sieve powder device.
Background technology
Sieve aperture in sieve in existing clinker fluffing sieve powder device is in operation and results in blockage, and often needs to shut down and removes, and could effectively work.And cleaning work for the treatment of amount is large, poor working environment, very inconvenient.Tracing it to its cause, is mainly that the arrangement mode of sieve aperture is improper.Sieve aperture is consistent with screen tray direction of rotation, and material is almost synchronous rotary with screen tray, causes material to be difficult for lower leakage from sieve aperture; Also because the effect that interests do not enter the wind-force in sieve powder device causes stopping up frequency high.The normal work of impact sieve powder device, thus cause energy consumption high, inefficient problem.
Summary of the invention
The purpose of this utility model is open a kind of clinker fluffing sieve powder device, to address the above problem, improves the effect of sieving of clinker, thereby increases output, reduces energy consumption.
The technical scheme of taking: clinker fluffing sieve powder device, comprise sieve and the disc shaped carrier of sieve is installed, wherein sieve is made fan-shapedly, is arranged on bracket by hold-down screw, forms a circular screen tray by polylith sieve; Sieve aperture in every sieve is made strip, along fan-shaped radially longitudinal arrangement.
The clinker fluffing sieve powder device of making like this, the sieve aperture of the arranged radially in the fan-shaped sieve of polylith of a screen tray of formation, forms outer endless belt, middle endless belt and three sieve aperture endless belt of interior endless belt.
Make in the manner described above a clinker fluffing sieve powder device, because the arrangement mode of sieve aperture is along fan-shaped arranged radially, coordinate with the wind direction that enters fluffing, there are interests to improve the through-rate of material, improve the performance by sieve aperture, thereby reduced the appearance of blockage problem.
Accompanying drawing explanation
Fig. 1 is clinker fluffing sieve powder apparatus structure schematic diagram.
Fig. 2 is the sieve powder apparatus structure schematic diagram of existing utilization.
The specific embodiment
Below in conjunction with accompanying drawing, as embodiment, technical scheme is further illustrated.
With reference to Fig. 2, the structure of existing clinker sieve powder device is the disc being made up of skeleton at, on skeleton, by the affixed fan-shaped sieve 5 of screw 3, forms a screen tray being set into by the fan-shaped sieve 5 of polylith.The problem of its existence is that the arrangement mode of sieve aperture is perpendicular to fan-shaped sieve radially, transversely arranged, cause processed granular material and to enter screen tray direction of rotation in sieving machine consistent, and also produced the rotating speed almost identical with screen tray motion in the same way on screen tray face by sieve material.Result in blockage frequent, the rate of sieving is low, increases energy consumption, and shutting down maintenance phenomenon number of times increases.
With reference to Fig. 1, present techniques is not change under the prerequisite of original sieve powder equipments overall structure, the spread pattern of the sieve aperture in fan-shaped sieve is made improvements, and makes it and the wind-force effect harmony entering in sieve powder device, reach the rate of sieving that improves, reduce the occurrence rate of clogging.Specifically the sieve aperture 4 in each fan-shaped sieve is made to strip, along fan-shaped sieve 5 arranged radiallys.Again the fan-shaped sieve screw 3 of making is fixed on the skeleton of sieve powder device.Like this, sieve aperture in every fan-shaped sieve 5 after assembling has just formed outer shroud sieve aperture band 1, middle ring grizzly pore area 2 and 6 three sieve aperture bands along fan-shaped sieve arranged radially of interior ring grizzly pore area, increase the resistance in rotatablely moving with screen tray by sieve material, more materials are sifted through sieve aperture 4.
The clinker fluffing sieve powder device of making like this, because sieve aperture is strip, and linear velocity direction while rotate with screen tray is perpendicular, the sieve powder effectively improving pass through performance, reduced the incidence of obstruction accident, thus reduction energy consumption, enhancing efficiency.
