На фиг. 1 изображен предлагаемый отстойник; на фиг. 2 - разрез А-А на фиг. 1.In FIG. 1 shows a proposed sump; in FIG. 2 is a section AA in FIG. 1.

Отстойник содержит корпус·1, бункер 2 и опору 3. В корпусе расположены наклонные (к горизонту ) перегородки 4, объединенные посредством боковин 5, стяжных шпилек 6, проставок и гаек в блоки 7. В отстойнике может’ быть два и большее четное число блоков . Каждый блок посредством проушин в боковинах 5 свободно подвешен на стержнях 8 подвески, перпендикулярных перегородкам 4. Стержни 8 неподвижно закреплены в стойках 9. В боковинах 5 неподвижно закреплены оси 10, на каждой из которых смонтирован радиальный подшипник качения 11, зафиксированный в осевом направлении. На крышке 12 установлен двигатель 13, на валу которого закреплен симметричный кулачок 14.

Суспензия подается через входной патрубок, медленно поднимается по щелям между перегородками 4, где из ; нее выпадает осадок и по перегородкам соскальзывает в бункер 2. Освет- 15 ленная жидкость сливается через сливной патрубок, а осадок уплотняется в бункере 2 и удаляется. При работе двигателя 13 кулачок 14, воздействуя на подшипники 11, обеспечивает коле- 20 бательные перемещения блоков 7 с перегородками 4 относительно стержней 8. За один оборот вала двигателя происходит два цикла колебаний каждого блока. При синхронном числе обо- 25 ротов в минуту двигателя 1500 и 3000 блоки будут колебаться с частотой соответственно 50 и 100 Гц. Предполагаемое устройство обеспечивает колебания каждой точки поверхности перего- βθ родки 4 'только в собственной ее плоскости и увеличение амплитуда колебания стержней от верхнего края пластин к нижнему по мере увеличения расстояния до стержней 8 подвески.The suspension is fed through the inlet pipe, slowly rises along the cracks between the partitions 4, where from; sediment precipitates and slides along the baffles into hopper 2. The clarified liquid is drained through the drain pipe, and the sediment is compacted in hopper 2 and removed. When the engine 13 is operating, the cam 14, acting on the bearings 11, provides oscillatory movements of the blocks 7 with the partitions 4 relative to the rods 8. For one revolution of the motor shaft, two oscillation cycles of each block occur. With a synchronous number of engine revolutions of 25 revolutions per minute 1500 and 3000, the units will oscillate with a frequency of 50 and 100 Hz, respectively. The proposed device provides vibrations of each point of the surface of the partition βθ of the 4 ′ only in its own plane and increases the amplitude of the oscillation of the rods from the upper edge of the plates to the lower as the distance to the suspension rods 8 increases.

Симметрия кулачка 14 и одновременное его воздействие на два блока обеспечивают нагружение двигателя только крутящим моментом (радиальные нагрузки симметричны), что обеспечивает долговечность двигателя. 40The symmetry of the cam 14 and its simultaneous action on the two blocks ensure that the engine is loaded only with torque (radial loads are symmetrical), which ensures engine durability. 40

В зависимости от свойств суспензии ,вибратор может работать постоянно или периодически.Depending on the properties of the suspension, the vibrator can work continuously or periodically.

Предложенный отстойник обеспечивает снижение трения между частицами осадка и вибрирующей перегородкой и, следовательно, удаление отстоя без опасности засорения осветленной. жидкости.The proposed sump provides a reduction in friction between the sediment particles and the vibrating partition and, therefore, the removal of sludge without the risk of clogging of clarified. liquids.

Claims

The invention relates to chemical processing devices for separating suspensions, and may be applied in the paint and varnish, pharmaceutical, food and other industries using apparatus for separating suspensions. A settling tank is known for separating suspensions, which contains a tank that is divided to intensify precipitation by inclined partitions into narrow slits, a hopper for compacting the sludge and a vibrator 13. Such a settling tank provides 6–10 times greater specific productivity than conventional septic tanks. This is associated with a well developed deposition surface, good conditions for precipitation and removal of sediment. However, the bulkhead suspension system is imperfect (probably traffic jams) and difficult to operate. The purpose of the invention is to increase the efficiency of use by ensuring the cleaning of partitions from sediments. The goal is achieved by the fact that in the settling tank containing a housing, a bunker for compacting the sediment, a package of parallel partitions with a vibrator, the package of partitions is made of two blocks and provided above the suspension level and perpendicular to the partitions, to which the blocks are freely suspended and between the latter and the vibrator and the spring. In addition, the vibrator is made in the form of a symmetrical cam mounted on the shaft of its engine, two radial bearings interacting with the cam, while the axes of the bearings and the shaft of the vibrator engine are located in a plane parallel to the axis of the suspension rods. FIG. 1 shows the 1st sediment bowl; in fig. 2 - section A-A in FIG. 1. The settling tank comprises a housing 1, a hopper 2 and a support 3. In the housing there are inclined (to the horizon) partitions 4, combined by means of sidewalls 5, fastening studs 6, spacers and nuts in blocks 7. B the sump may be two or more even number of blocks. Each block through the lugs in the sidewalls 5 is freely suspended from rods 8 of the suspension, perpendicular to the partitions 4. The rods 8 are fixedly fixed in the uprights 9. In the sidewalls 5, the axes 10 are fixedly mounted, each of which has a radial rolling bearing 11 fixed in the axial direction . A motor 13 is mounted on the lid 12, on the shaft of which a symmetrical cam 14 is fixed. Bearings 11 are centered around the CTiBOM. Springs 15 are pressed to the side surface of the cam 14. The settling tank works as follows. The suspension is fed through the inlet, slowly rising between the partitions 4 where a precipitate falls out of it and slides over partitions into bunker 2, the clarified liquid is drained through a drain pipe, and the sediment condenses in bunker 2 and is removed. When the engine 13 operates, the cam 14, acting on the bearings 11, provides oscillatory movements of the blocks 7 with partitions 4 relative to the rods 8. During one revolution of the motor shaft, two oscillations of each block occur. At a synchronous engine rpm of 1500 and 3000, the blocks will oscillate with a frequency of 50 and 100 Hz, respectively. The proposed device only oscillates each point of the surface of the partition 4 in its own plane and increases the amplitude of the rods from the upper edge of the plate to the bottom as the distance to the suspension rods 8 increases. The symmetry of the cam 14 and its simultaneous impact on the two blocks both heat the engine with torque only (radial loads are c), which ensures engine durability. Depending on the properties of the suspension, the vibrator can work continuously or periodically. The proposed sump provides reduction of friction between the sediment particles and the vibrating partition and, consequently, the removal of sludge without the danger of clogging of the clarified liquid.
