Abstract

The utility model belongs to the technical field of cement production equipment, and provides a static classifying conveyer, which is applied to classifying and conveying materials among the cement production equipment. The static classifying conveyer is mainly characterized by comprising a classifying plate mounted between a hoister and a 'V'-shaped powder concentrator or a crusher, grate bars are arranged in a frame to form the classifying plate, the section of each grate bar is a trapezoid with a wide top and a narrow bottom, an elongated sieve pore is formed between each two grate bars, the included angle between the classifying plate and a horizontal plane ranges from 20 degrees to 80 degrees, and a fine powder collecting hopper is arranged at the bottom of the classifying plate. The static classifying conveyer is capable of not only conveying materials but also classifying the materials, and is simple in structure and high in operating efficiency, energy is saved, and emission is reduced.

Description

A kind of static rank transport

Technical field

The utility model belongs to the cement manufacture plant technical field, relates to a kind of static rank transport, is mainly used in the classification and the conveying of material between cement manufacture plant.

Background technology

At present, the manufacture of cement industry will be carried out the branch powder mill to material in the process of cement processing, sorting classification operation such as grinding more again, and existing stock grading generally adopts beater, " V " shape powder concentrator, equipment such as pulverized-coal collector.Being provided with at these equipment and equipment room and being connected pipeline, has been pure conveying function and connect pipeline, does not possess classifying capability.This technological process in use power consumption is very big, and the production cost that this has not only increased enterprise does not meet the energy-saving and emission-reduction requirement that country advocates.

Summary of the invention

The inventor is in the daily course of work; Find that existing manufacture of cement industry exists above-mentioned defective to the material grinding classification time; Through constantly explore improving, the utility model technical problem to be solved provide a kind of simple in structure, efficient is high, energy-conservation, the static rank transport that can convey materials can divide stage material again.

For solving the problems of the technologies described above; The technical scheme that the utility model is taked is that the structure of this static rank transport comprises the graded plate that is installed between elevator and " V " shape powder concentrator or beater; Said graded plate is in framework, to establish grating, and the grating cross section is a trapezoidal shape wide at the top and narrow at the bottom, forms long strip sieve pores between adjacent grating; The angle of graded plate and horizontal plane is established the fine powder aggregate bin at 20 °-80 ° at the lower bottom part of graded plate.

Formed long strip sieve pores between said adjacent grating, the sieve aperture width is between 0.2-2mm.

In order effectively material to be carried out classification; Said graded plate can be established upper strata graded plate and lower floor's graded plate; Formed long strip sieve pores width is between 2-8mm between the adjacent grating of upper strata graded plate, and formed long strip sieve pores width is between 0.2-2mm between the adjacent grating of lower floor's graded plate.

The utility model adopts technique scheme between classifying equipoment, to be provided with the graded plate of certain gradient; Material is after getting into graded plate through elevator; Rely on the gravity of himself, can carry along graded plate, the sieve aperture on the graded plate carries out classification to material simultaneously; Can carry out classification once more to material when using the double-layer separate step; The utility model not only has between existing classifying equipoment and to connect the conveying function that pipeline rose, and the while can be carried out hierarchical processing to material, and simple in structure, high efficiency, energy-saving and emission-reduction.

The specific embodiment

Specify below in conjunction with the structure of accompanying drawing a kind of static rank transport of the utility model.

Referring to Fig. 1; Fig. 3, Fig. 4, the structure of a kind of static rank transport of the utility model comprises the graded plate 2 that is installed on 4 of elevator 1 and " V " shape powder concentrators (or beater grader); Graded plate 2 is in framework, to establish grating 6; Grating 6 cross sections are trapezoidal shape wide at the top and narrow at the bottom, and 6 of adjacent gratings form long strip sieve pores 7, the sieve aperture width between 0.2-2mm to adapt to the classification demand of different material; The angle of graded plate 2 and horizontal plane 20 °-80 ° guaranteeing that material relies on the gravity of himself to be transferred along graded plate 2 on graded plate 2, establish fine powder aggregate bin 3 at the lower bottom part of graded plate 2 and be used to collect the powder material that come out by classification.

Referring to Fig. 2; In order effectively material to be carried out classification; Graded plate can be established two-layer; Below graded plate 2 (upper strata graded plate), set layer graded plate 5 again, formed long strip sieve pores width is located between 2-8mm between graded plate 2 adjacent gratings, and formed long strip sieve pores width is located between 0.2-2mm between lower floor's graded plate 5 adjacent gratings.

The utility model is installed in elevator 1 and " V " shape powder concentrator (or beater grader) between 4; When work; Material classified plate under no extrinsic motive of carrying from elevator 1 carries out classification; The qualified fine powder of separating gets into next procedure, meal then get into down the road classifying equipoment carry out classification or directly get under road equipment pulverize again, and then be transported to elevator and carry out hierarchical processing.The utility model not only has conveying function, and can carry out hierarchical processing to material simultaneously, and simple in structure, high efficiency.
