Кроме того, целесообразно гидроциклон выполнять в виде усеченного конуса, большее открытое основание которого размещено в отстойнике ниже уровня перегородки.In addition, it is advisable to perform a hydrocyclone in the form of a truncated cone, the larger open base of which is located in the sump below the level of the partition.

На чертеже представлено устройство для очистки эмульсии, общий вид.The drawing shows a device for cleaning the emulsion, General view.

Устройство для очистки эмульсии состоит из отстойника 1 с перегородкой 2, гидроциклона 3, патрубка 4 для удаления шлама, смонтированного в нижней части отстойника 1, насоса 5 для подачи эмульсии в гидроциклон 3 для очистки и разделения. Гидроциклон 3 содержит активатор 6, выполненный из ленты в виде конической спирали, малый диаметр которой направлен в сторону отстойника. Витки активатора 6 выполнены с зазором 7 между друг другом и имеют коническую форму, при этом меньший диаметр витков активатора 6 направлен также в сторону отстойника. Активатор 6 закреплен на подпружиненной плите 8, которая соединена с направленным вибратором 9..The device for cleaning the emulsion consists of a sump 1 with a partition 2, a hydrocyclone 3, a pipe 4 for removing sludge mounted in the lower part of the sump 1, a pump 5 for feeding the emulsion into a hydrocyclone 3 for cleaning and separation. The hydrocyclone 3 contains an activator 6 made of a tape in the form of a conical spiral, the small diameter of which is directed towards the settler. The turns of the activator 6 are made with a gap 7 between each other and have a conical shape, while the smaller diameter of the turns of the activator 6 is also directed towards the sump. The activator 6 is mounted on a spring-loaded plate 8, which is connected to a directional vibrator 9 ..

Корпус гидроциклона 3 выполнен в виде усеченного конуса, закрепленного малым основанием к плите 8 и подпружиненного большим открытым основанием в отстойник 1. В плиту 8 вмонтированы патрубок 10 для подачи эмульсии на очистку и патрубок 11 для отсоса очищенной эмульсии. Нижнее малое основание активатора 6 образует шламовое отверстие 12. Отстойник 1 снабжен патрубком 13 с затвором 14 для слива воды и масла, и патрубок 15 за перегородкой 2 для слива воды. В патрубок 4 вмонтированы на разной высоте два затвора 16 и 17, управляемые общей рукояткой 18.The body of the hydrocyclone 3 is made in the form of a truncated cone, fixed by a small base to the plate 8 and spring-loaded with a large open base into the sump 1. A nozzle 10 is mounted in the plate 8 for supplying the emulsion for cleaning and a pipe 11 for suctioning the cleaned emulsion. The lower small base of the activator 6 forms a sludge hole 12. The sump 1 is equipped with a pipe 13 with a shutter 14 for draining water and oil, and a pipe 15 behind the partition 2 for draining water. In the pipe 4 are mounted at different heights two shutters 16 and 17, controlled by a common handle 18.

Устройство работает следующим образом.The device operates as follows.

Отработанная эмульсия от волочильных станов (или других агрегатов или станков) централизовано подается насосом 5 через патрубок 10 $ в гидроциклон 3, где происходит закручивание струи по спиральным виткам активатора 6 при одновременном движении ее вниз. За счет центробежных сил твердые частицы перемещаютЮ ся к внутренней поверхности витков активатора 6 и по ним постепенно стекают в сторону выходного шламового отверстия 12, через которое шлам загружается в патрубок 4 в 15 зону между затворами 16 и 17.The spent emulsion from drawing mills (or other units or machines) is centrally supplied by pump 5 through a $ 10 nozzle to hydrocyclone 3, where the jet is twisted along spiral turns of activator 6 while moving it down. Due to centrifugal forces, solid particles move to the inner surface of the turns of the activator 6 and gradually flow down them towards the outlet sludge hole 12, through which the sludge is loaded into the pipe 4 in the 15 zone between the gates 16 and 17.

По мере накопления шлама между затворами 16 и 17 рукояткой 18 закрывают затвор 16, открывают затвор 17 и тем самым порционно выг20 ружают шлам. В дальнейшем цикл повторяется.As the sludge accumulates between the shutters 16 and 17, the shutter 16 is closed by the handle 18, the shutter 17 is opened, and thereby the slurry is batch removed. Subsequently, the cycle repeats.

Вибратор ?,связанный с плитой 8, приводит в движение активатор 6 и конический корпус с гидроциклона 3, 25 которые в процессе колебаний активизируют одновременно перемещение твердых частиц вниз по стенкам активатора 6 и активизируют за счет ступенек образуемых витками ленты при течении 30 по ним жидкости, разделение (снятие масла) агрегатов частиц эмульсии под действием гидродинамического удара, возникающего от вибрации. Кроме того, конический корпус гидроциклона 35 3, вибрируя в вертикальном направлении в отстойнике 1, за счет разности удельной массы воды и масла и центробежной скорости, разбрасывает воду по основанию отстойника 1, а масло 40 под корпус гидроциклона 3. Накопившаяся в отстойнике 1 вода перетекает через перегородку 2 и удаляется через патрубок 15, а масло, скопившееся под коническим корпусом гидроциклона 3, 45 циклически удаляется через патрубок 13.The vibrator? Connected with the plate 8, activates the activator 6 and the conical body from the hydrocyclone 3, 25 which during the oscillation process simultaneously activate the movement of solid particles down the walls of the activator 6 and activate due to the steps formed by the turns of the tape with 30 fluid flowing through them, separation (removal of oil) of the aggregates of the particles of the emulsion under the influence of hydrodynamic shock arising from vibration. In addition, the conical body of the hydrocyclone 35 3, vibrating in the vertical direction in the sump 1, due to the difference in the specific gravity of water and oil and centrifugal speed, scatters water at the base of the sump 1, and oil 40 under the body of the hydrocyclone 3. The water accumulated in the sump 1 flows through the partition 2 and is removed through the pipe 15, and the oil accumulated under the conical body of the hydrocyclone 3, 45 is cyclically removed through the pipe 13.

При увеличении подачи эмульсии через патрубок 10, зазор 7 между витками активатора 6 автоматически увелиj₀ чивается, вследствие увеличения диаметра витков под действием центробежной силы потока., что приводит к равно мерной очистке при различных условиях подачи эмульсии.With an increase in the emulsion supply through the nozzle 10, the gap 7 between the turns of the activator 6 automatically increases ₀ due to the increase in the diameter of the turns under the action of the centrifugal flow force., Which leads to uniform cleaning under different conditions of the emulsion supply.

Предлагаемое устройство может работать в двух режимах, В первом режиме при очистке загрязненной эмульсии и требующей обогащения. При этом пат5 899148 А рубок 13 закрыт затвором. 14, а откачка очищенной эмульсии производится через патрубок 11. Во втором режиме отработанная и не пригодная для использования в производственном цикле эмульсия разделяется устройством на воду, которую допустимо сливать в канализацию, а масло циклически отводится через патрубок 13 в емкости и сдается как отходы, используемые для форсуночных топок, при этом откачка через патрубок 11 не производится.The proposed device can operate in two modes, In the first mode, when cleaning a contaminated emulsion and requiring enrichment. In this case, Pat5 899148 A felling 13 is closed by a shutter. 14, and pumping out the purified emulsion through the nozzle 11. In the second mode, the emulsion worked out and not suitable for use in the production cycle is separated by the device into water, which can be drained into the sewer, and the oil is cyclically discharged through the nozzle 13 into the tank and disposed of as waste used for nozzle furnaces, while pumping through the pipe 11 is not performed.

Таким образом, предлагаемое устройство обеспечивает многократную качественную очистку эмульсии в непрерывном режиме в процессе волочения медной проволоки и периодической очистки волочильных машин от отработанной эмульсии в нерабочие дни для подготовки агрегатов под заправку новой эмульсией.Thus, the proposed device provides multiple high-quality cleaning of the emulsion in a continuous mode during the drawing of copper wire and periodic cleaning of drawing machines from the spent emulsion on non-working days to prepare the units for refueling with a new emulsion.

Изобретение обеспечивает так же хорошее разделение эмульсии для утилизации масла и возможности его вторичного использования в качестве топлива, слив воды в канализацию без ее загрязнения маслами и значительно лучшую очистку шлама от масел, позволяющую в кондиционном виде отправлять отходы окиси меди на переработку цветной металлургии.The invention also provides good separation of the emulsion for oil utilization and the possibility of its secondary use as a fuel, draining water into the sewer without oil contamination, and significantly better oil sludge purification, which allows for the conditional transfer of copper oxide waste to non-ferrous metallurgy processing.
