Изобретение относитс к разделению кусковых материалов, а именно к классифицирующим вибрационним ситам и может быть применено в горной промышленности, промышленности строительных материалов и других област х.The invention relates to the separation of lump materials, namely to classification vibration screens and can be applied in the mining industry, the building materials industry and other areas.

Известно вибрационное сито дл сортировки руд и других материалов, в котором одна система колосников соединена непосредственно с сердечником вибродвигател , а друга - с корем 1.A vibrating screen for sorting ores and other materials is known, in which one grate system is connected directly to the core of the vibromotor and the other to the core 1.

Недостатком устройства вл етс низка эффективность отсева мелкого материала.The disadvantage of the device is the low efficiency of screening of fine material.

Известно другое вибрационное сито, содержашее привод и два размешенных один над другим независимо св занных с приводом рабочих органа в виде колосниковых решеток 2.Another vibratory sieve is known, the contained drive and two placed one above the other, independently connected to the drive, are working bodies in the form of grates 2.

В процессе работы за счет взаимного перемещени колосников происходит разделение материалов и самоочишение рабочих шелей от налипаюших частиц. Это устройство вл етс наиболее близким к изобретению по технической суш,ности и достигаемому результату .In the course of work, due to the mutual displacement of the grates, materials are separated and the working shells are self-cleaning from the sticking particles. This device is closest to the invention in terms of technical drying, and the result achieved.

Однако устройство имеет недостаточно высокое качество конечного продукта, поскольку крупные плоские части могут попадать в подрешетный продукт через прот женные щели между колосниками.However, the device has an insufficiently high quality of the final product, since large flat parts can get into the undersize product through the extended gaps between the grate bars.

Цель изобретени - повышение точности классификации трудногрохотимых и мелких материалов.The purpose of the invention is to improve the accuracy of classification of hard and small materials.

Это достигаетс тем, что в вибрационном сите, содержащем привод и два размещенных один над другим независимо св занных с приводом рабочих органа, нижний рабочий орган выполнен в виде поддона и снабжен штыр ми с конусными головками, соответствующими в поперечном сечении форме отверстий верхнего рабочего органа и расположенными внутри них с образованием кольцевой щели.This is achieved by the fact that in a vibrating sieve containing a drive and two working members placed one above the other independently connected to the drive, the lower working member is made in the form of a pallet and provided with pins with tapered heads corresponding in cross section of the openings of the upper working member and located inside them with the formation of an annular gap.

На чертеже представлена схема предлагаемого сита.The drawing shows the scheme of the proposed sieve.

Claims

The sieve consists of a vibrating drive 1, a box 2, an upper working body 3 with openings 4 and a lower working body in the form of a pallet 5, equipped with tongues 6 with conical heads 7 and legs 8 in the form of inverse cones. The conical heads 7 of the pins 6 correspond in cross section to the shape of the holes 4 of the upper working body 3. The pins of the pallet 6 with the conical heads 7 are located inside the openings 4 of the upper working organ 3, forming an annular gap 9. The drive 1 is connected to the pallet 5 and the box 2 by means of elastic st sieves 10 and 11. The sieve is equipped with funnels 12, 13 and 14 for feeding the material and unloading the products. Suspended or supporting shock absorbers 15 are used to isolate the overlap from vibration. The device operates as follows. When the vibration drive 1 is turned on, the duct 2 with the upper working body 3 and the tray 5 begin to perform antiphase oscillations. The source material is fed through the funnel 12. Large material iodine is vibrated through the working body 3 into the funnel 14, and the fine material passes through the annular slots 9 formed by the holes 4 and the pins 6 on the pallet 5 and is transported through it to the discharge funnel 13. The application of the invention allows to improve the quality of the final product by 7-15 / o. The invention formula Vibrating sieve for the classification of lumpy materials containing a drive and two placed one above the other independently connected with the drive of working bodies, differing Moreover, in order to improve the classification accuracy of hard and fine materials, the lower working member is made in the form of a pallet and provided with a pin with conical heads, corresponding in cross section to the shape of the openings of the upper working member and inside them with the formation of К0оты1, Eva slit.
