С54) ЛЕНТОЧНЫЙ ФИЛЬТР-ПРЕССC54) BELT FILTER PRESS

II

Изобретение относитс к устройствам дл глубокого обезвоживани суспензий , преимутчественно цементносырьевых шламов, и может быть исполь- эовано в области строительных мате- риалов,горнорудной,химической,пищевой и других отрасл х промышленности. I Известен ленточный фильтр дл обезвоживани суспензий,содержащий фильтрующую ленту,уложенную на бееко- иечный конвейер,выполненный иэ звеньев и привод С11 The invention relates to devices for the deep dewatering of suspensions, mainly cement and sludge, and can be used in the field of building materials, mining, chemical, food and other industries. I Known belt filter for dewatering suspensions, containing filter tape, laid on the wire conveyor, made of links and drive C11

Недостатками известного фильтра вл ютс мала активно работающа площадь фильтровальной д1ентЫ, преры- tS вистрсть процесса обезвоживани .The disadvantages of the known filter are the small actively working area of the filter element, the interruption of the dehydration process.

Цель изобретени - увеличение фильтрующей поверхности фильтра при сохранении его габаритов.The purpose of the invention is to increase the filtering surface of the filter while maintaining its dimensions.

Поставленна цель достигаетс тем, 20 что фильтр снабжен лентоукладчйком и перфорированными рамками с уплотнени ми , причем рамки укреплены на звень х с наружной стороны конвейера.The goal is achieved by the fact that the filter is provided with a band-laying and perforated frames with seals, the frames being fixed to the links on the outside of the conveyor.

На фиг. 1 изображён фильтр, общий 25 вид; на фиг. 2 - узел I на фиг. 1; на фиг. 3 - вид по стрелке А. . ,FIG. 1 shows a filter, a general 25 species; in fig. 2 — node I in FIG. one; in fig. 3 - view along arrow A.. ,

Фильтр состоит из двойного бескр- , нечного конвейера 1, выполненного из звеньев 2 с закрепленными на них пер-30The filter consists of a double unlinked, non-continuous conveyor 1, made of links 2 with lane-30 fixed on them

форированньйни рамками 3, снабженными уплотнени ми 4 и опорными роликами 5. Конвейер перемещаетс через приводные и нат жные звездочки 6 и 7 и поддерживаетс верхней и нижней направл ющими 8 и 9. Фильтрующа лента 10 выполнена из влагопрРвод щей ткани вне зоны рамок цепи располагаетс на напрарл кицих и поддерживающих роликах 11 .и 12. Дл обеспечени непрерывного движени и складчатой укладки ткани между рамками конвейера служит лентоукладчик 13, выполненный в виде т говоукладочного механизма. Все узлы смРИтированы на раме 14, на которой закреплены приспособлени 15 и 16 дл заливки суспензии и регенерации ткани. Разгрузка обезвоженного осйдка происходит на транспортер 17.Formed frames 3, provided with seals 4 and support rollers 5. The conveyor moves through the drive and tension sprockets 6 and 7 and is supported by the upper and lower guides 8 and 9. The filter belt 10 is made of moisture-wicking fabric outside the chain frames and is located on the rear Kitsi and supporting rollers 11. and 12. For ensuring continuous movement and folded laying of the fabric between the frames of the conveyor, a paver 13 is used, made in the form of a folding mechanism. All units are identified on the frame 14, on which the fixtures 15 and 16 are fixed for pouring the suspension and regenerating the tissue. Unloading dehydrated osidka occurs on the conveyor 17.

Устройство рйботает следующим образом .The device works as follows.

Claims

Conveyor 1 with frames 3 is continuously moving. At the same time, in the place of its inflection, the asterisks 6 and 7 open out like a fan, and in the sections between the asterisks of the frame 3 they move in a dense vertical row. Using the paver 13, the filter tape% 0 is pushed into the open spaces of frames 3 and then, with the next frame taken up, the folds are clamped by seals 4 of frames 3 to form a row of movable flat bags opened upwards. Continuous filling of the suspension in the cavity of pinched tape folds from the side of its laying is carried out through the filling device 15. During the time of movement from the sprocket 7 to the sprocket 6, the suspension is poured into the folds of the filter of the tape 10, separates the ylagu which flows by gravity through the opening. at the end of the frame 14. At the end of the row behind the two folds of the frame 3 of the conveyor 1, the sprocket 6 is spread out and the filter tape 10, released from the clamp, is pulled together with the suspension of the suspension onto the guide roller 11. When the filter roll is bent Through this roller, a dehydrated sludge separates, which gets onto the conveyor 17. THE LOADING Upper and idle and lower branches of the conveyor 1 move linearly in the directions 8 and 9, supported by the rollers 5 located on the axles of the conveyor hinges. After the dehydrated sediment has been discharged, the filter belt 10 is cleaned in the regeneration unit of the device 16 and, supported by the rollers 12, passes through the guide roller 11 to the binder 13. The dewatering process takes place continuously. Claim filter belt for shaping slurries, mainly cement slurry sludge, containing filter tape, laid on an endless conveyor made of links and a drive that is different, in order to increase the filter surface of the filter while maintaining its dimensions, the filter is equipped with a grinder and perforated frames with seals, the frames being fixed on the links from the outer side of the conveyor.
