Изобретение относитс к технике фильтровани при разделении суспензии , а также очистке жидкости и может быть использовано в химической и других отрасл х промышленности , где примен ютс процессы фильтровани .The invention relates to a filtering technique for separating a slurry as well as cleaning a liquid, and can be used in the chemical and other sectors of the industry where filtering processes are used.

Известен фильтр дл очистки жидкости , включающий корпус, разделенный по высоте фильтровальными дисками на камеры исходной суспензии и фильтрата, коробы с прог ивной камерой , укрепленные на валу, выполненном с каналом дл промывной жидкости 1 .A filter for cleaning fluid is known, which includes a housing divided in height by filter discs into chambers of the initial suspension and filtrate, boxes with a progressive chamber, mounted on a shaft made with a washing liquid channel 1.

Однако этот фильтр непригоден дл случаев, когда целью разделени вл етс получение ценного осадка; при его использовании неизбежны потери готового продукта - фильтрата на промывку фильтрующих элементов; необходимо повышение давлени фильтрата дл интенсификации промывки фильтрующего элемента, особенно от более плотных взвесей, что требует увеличени толщины корпуса фильтра, а, следовательно, его массы и стоимости .However, this filter is unsuitable for cases where the goal of separation is to obtain valuable sludge; when it is used, the loss of the finished product is inevitable - filtrate for washing the filter elements It is necessary to increase the pressure of the filtrate to intensify the washing of the filter element, especially from denser suspensions, which requires an increase in the thickness of the filter housing, and, consequently, its mass and cost.

Целью изобретени вл етс повышение производительности и расширение области применени фильтра.The aim of the invention is to increase productivity and expand the field of application of the filter.

Это достигаетс тем, что коробы снабж-ены камерами продувки и удалени осадка, а вал выполнен с каналами продувки и удалени осадка, соединенными с соответствующими камерами , причем фильтр снабжен допол0 нительными коробами, установленными зеркально основным, камеры которых соединены с соответствующими каналами вала.This is achieved by the fact that the boxes are provided with chambers for blowing and removing sediment, and the shaft is made with channels for blowing and removing sediment connected to the respective chambers, and the filter is equipped with additional boxes installed mirror-like main chambers of which are connected to the corresponding channels of the shaft.

Claims

A filter for separating suspensions, includes a housing 1, filtering elements. Copies 2, mirrored on both sides of the filter elements of the box 3 with the lapping plates 4 and springs 5, are equipped with chambers that are connected to the corresponding channel of the rotating cotton 6. The filter has nozzles 7 for supplying the suspension and nozzles 8 for removing the filtrate, driving the shaft, for example pulsating type, ss standing out of the ratchet wheel 9, the pusher 10, the spring 11 and the cylinder 12, There is also a collector 13 for supplying and discharging washing liquid, gases and removing sediment. The filter works as follows. The suspension under pressure enters through the pipe 7 into the housing 1 and with the help of filtrating elements 2 is divided into pure filtrate and wet sediment. The filtrate is discharged through patches 8. Through the collector 13, the channels of the shaft b, the chamber of the duct 3 and the holes in the lapping plates 4, the precipitate is washed and purged and removed by gas or liquid. The lapping plates 4 with the box 3 are pressed against the filter elements 2 by the springs 5 and the fluid pressure in the filter chambers i The boxes 3, rigidly connected to the rotating shaft, move relative to the filter elements 2, clearing them, after receiving the command from the automatic device that responds to clogging of filter elements above a given rate. The shaft 6 is moved from the hydraulic or pneumatic cylinder 12 through the pusher 10 and the ratchet wheel 9. This drive allows you to adjust the duration of the npoivMBKH, purge and remove sediment during the continuous filtering process. The use of the present invention allows to obtain a precipitate or a filtrate at a lower cost of production areas and to increase the productivity compared with other types of similar filtrates. Claims filter for separating suspensions, comprising a housing divided by height by filtering discs into chambers of initial suspension and filtering, boxes with a washing chamber fixed on a shaft made with a channel for washing liquid, so as to increase productivity filter due to its continuous operation, the boxes are equipped with chambers for purging and removing sediment, and the shaft is made with channels for purging and removing sediment connected to the respective chambers, the filter being supplied. additional boxes ,. mirror-mounted, the cameras of which are connected to the corresponding channels of the shaft. ; Sources of information taken into consideration during the examination 1.
