Изобретение относитс к обогащению полезных ископаемых, в частности дл промывки нерудных строительных материалов, руд и флюсов.The invention relates to the beneficiation of minerals, in particular for the washing of non-metallic building materials, ores and fluxes.

По основному авт. св. № 882605 известна вибрационна промывочна машина, включающа вибратор, подвески с амортизаторами , привод, загрузочные и разгрузочные приспособлени , а также рабочие камеры в виде барабанов, выполненные в виде сменных сборных кассет из пластинок износостойкого материала, например резины или полиуретана, собранных на продольных стержн х 1.According to the main author. St. No. 882605 is a known vibratory washer comprising a vibrator, suspension with shock absorbers, a drive, loading and unloading devices, and working chambers in the form of drums made in the form of replaceable collection cassettes of wear-resistant material plates, for example rubber or polyurethane, assembled on longitudinal rods one.

Недостатком такой вибрационной промывочной маигины вл етс то, что при изменении степени загр зненности исходного материала невозможно регулировать процесс промывки, измен параметры колебаний и врем промывки.The disadvantage of such a vibratory wash is that when changing the degree of contamination of the source material, it is impossible to control the washing process, changing the vibration parameters and the washing time.

Цель изобретени - повыщение качества промываемого продукта и регулирование производительности машины.The purpose of the invention is to increase the quality of the product being washed and to regulate the productivity of the machine.

Указанна цель достигаетс тем, что вибрационна промывочна машина снабжена двум дополнительными вибраторами с автономными приводами, при этом всеThis goal is achieved by the fact that the vibratory washer is equipped with two additional vibrators with autonomous drives, while all

вибраторы имеют регулируемые амплитуды и различные частоты колебаний.Vibrators have adjustable amplitudes and different vibration frequencies.

Вибрационна промывочна мащина сострит из двух поперечных пластин 1, в торых закреплены рабочие камеры 2 и трубы 3. В трубах 3 в подшипниках вращаютс вибраторы 4.The vibratory flushing machine is composed of two transverse plates 1, in which the working chambers 2 and the tubes 3 are fixed. In the pipes 3 in the bearings the vibrators 4 rotate.

Вал вибратора 4 имеет в средней части неуравновешенную массу 5, на его концах на шлицевом соединении 6 закреплены де15 балансы 7.The shaft of the vibrator 4 has an unbalanced mass 5 in the middle part, at its ends on the spline connection 6 there are fixed 15 balances 7.

Claims

The drive of the machine includes couplings 8, drive shafts 9 and electric motors 10. Electric motors 10 are fixed on narame 11. With supports 12, the machine rests on shock absorbers 13 (springs or pneumatic cylinders), which are fixed on plates 14. Working chambers 2 are fixed in plates 1 with brackets 15, fingers 16 and bolts 17 and have hoppers 18 and unloading thresholds 19 with the ability to rotate the latter and change the level of loading cameras

2. In the lower part of chambers 2 there are nozzles 20 for exit of contaminated water and sludge, in the upper part of chambers 2 pipes 21 are mounted with splashes 22 for supplying water for washing. The working surfaces of the chambers 2 are made of plates 23 in the form of cassettes 24 fastened with rods. Vibration washer works as follows. The vibrators 4 are started, when the operating mode is established, water is supplied through the pipes 21 and the chambers 2 are loaded with raw material through the hoppers 18. Under the influence of vibrations, the material is intensively moved in the chambers 2, washed with water and discharged from the machine through the rapids 19. Sludge impurities the water is removed from the machine through the nozzles 20. When flushing various sources of contamination of the starting material, the vibratory washer is adjusted by varying the vibration amplitude. This is done by rotating the unbalance 7, when their mass, for example, is phase aligned with the unbalanced weight 5 of the vibrator shaft 4 (both masses are located simultaneously below the vibrator axis) and receives the maximum vibration amplitude, which is necessary with the greatest contamination of the material being washed. In the case of washing the less polluted material, the unbalances 7 are set in antiphase with a mass of 5 the shaft of the vibrator 4 and receive the minimum amplitude of oscillations. If the difference in the position of the phases of the masses 5 and the unbalances 7 is 180 °, oscillations are not reported to the machine. The vibrators 4 rotate at 750, 1000 and 1500 rpm. The proposed vibratory washer has advantages over the known washers, in that it is possible to efficiently wash the material (e.g., gravity) with inclusions of lumpy clay of different ductility and control of the productivity of the machine. This is achieved by adjusting the required mode of operation of the machine depending on the washability of the material by varying the amplitude of vibrations of vibrators having different oscillation frequencies. Vibration flushing machine according to aut. St. No. 882605, characterized in that, in order to improve the quality of the product being washed and to adjust the performance of the machine at varying degrees of contamination of the source material, it is equipped with two additional vibrators with autonomous drives, all vibrators having adjustable amplitudes and different vibration frequencies.
