Description

Изобретение относитс к процессам фильтровани , а именно к фильтрам, предназначенным дл очистки ЖИДКОСТИ.This invention relates to filtration processes, namely filters designed to purify LIQUID.

Известен фильтр дл очистки жидкости, содер}кащий корпус с патрубками, перфорированную решетку и фильтрующий слой, выполненный из нитей, одни концы которых закреплены на перфорированной перегородке 1.A filter for cleaning liquids is known, containing a housing with nozzles, a perforated grille and a filtering layer made of filaments, one ends of which are fixed on a perforated partition 1.

Недостатком фильтра вл етс мала гр зеемкость.The disadvantage of the filter is low holding capacity.

Указанный недостаток частично устранен в фильтре, содержащем корпус с патрубками дл входа и выхода, подвижную и неподвижную перфорированные перегородки и заключенный между ними фильтрующий слой из отдельных нитей, концы которых закреплены на перегородках 2. , Недостатком фильтра вл етс также мала гр зеемкрс ть н плоха регенераци фильтрующего сло .This disadvantage is partially eliminated in the filter, which contains a housing with inlets and outlets, movable and stationary perforated partitions and a filtering layer between them that consists of separate threads, the ends of which are fixed on the partitions 2. regeneration of the filter layer.

Целью изобретени вл етс повышение эффективности работы фильтра путем увеличени его гр зеемкости и улучшени регенерации его фильтрующего сло .The aim of the invention is to increase the efficiency of the filter by increasing its drain capacity and improving the regeneration of its filter layer.

Указанна цель достигаетс тем, что нити фильтрующего сло выполнены переменного сечени по их длине, установлены параллельно и скрепле1 Ы мёжду собой, причем сечение нитей увеличиваетс в сторону подвижной перфорированной перегородки.This goal is achieved by the fact that the filaments of the filter layer are made of variable cross-section along their length, are installed in parallel and fasten between them, with the cross-section of the filaments increasing towards the movable perforated partition.

На фиг. 1 показан предлагаемый фильтр в период фильтрации; на фиг. 2 - то же в период регенерации.FIG. 1 shows the proposed filter during the filtration period; in fig. 2 - the same during the regeneration period.

Фильтр состоит из корпуса 1 с входным патрубком 2 и выходным патрубком 3. В корпусе установлена неподвижна перфорированна перегородка 4 и подвижна перфорированна перегородка 5. Между перегородками 4 и 5 смонтированы параллельно расположенные Нити 6 переменного сечени , которые по длине скреплены между собой нит ми 7. Нити 6 могут быть выполнены с плавно измен ющимс сечением по длине и ступенчато. Сечение их увеличиваетс в cTopoiiy подвижной перегородки.The filter consists of a housing 1 with an inlet nozzle 2 and an outlet nozzle 3. A fixed perforated partition 4 and a movable perforated partition 5 are installed in the case. The yarns 6 can be made with a smoothly varying section in length and in steps. Their cross section increases in the cTopoiiy of the movable partition.

Фильтр работает следующим образом.The filter works as follows.

Claims

When filtering the original fluid through the inlet pipe 2 enters the housing. In this case, the movable perforated partition 5 is lowered under the action of its own weight and resistance forces and occupies the lower position, and the b threads, due to a multiple decrease in the distance of the memory, partitions are assembled on the fixed perforated partition i and repeatedly overlap each other and form a porous filter layer sandwiched between partitions. In this case, the threads 7, by means of which the threads 6 are fastened, prevent the entangling of adjacent nantes 6 between themselves. The pore size in the thickness of the filtering layer varies from the maximum value on the liquid inlet side to the minimum on the output side of the purified liquid. The passage of the filtering layer, dirt particles present in the source fluid are retained in the pores of the filtering layer. Moreover, the largest particles are retained in (The top part of the filter layer (where the pores are the largest), and the smallest particles are retained in the pores of the bottom part of the filter layer (where the pores are the smallest). After filling the pores of the filter layer with inclusions contained in the original liquid , regeneration of the filter is carried out. When regenerating, the filtered LIQUID goes through the nozzle 3. When the filter layer meets on its way, the liquid flow loosens it and moves the movable perforated partition 5 which carries the threads 6 fixed on it. At the same time, the pores between the threads 6 are multiplied many times, and the contaminants retained in the pores of the filtering layer by the fluid flow are removed from the filter. The filter regeneration time depends on the characteristics of the original liquid contaminants filing between filaments parallel to the variable cross-section filaments ensures that the filtration layer is formed during filtration with pores whose size varies from the maximum value from side to side. the progress of the original fluid to the minimum side of the exit of the purified liquid. Accordingly, the largest inclusions are retained at the top of the filter bed, while the smallest inclusions are retained in the pores of the bottom of the filter bed. Thus, the contaminants contained in the initial liquid are retained throughout the entire thickness of the filtering layer, which allows a 1.4–1.8-fold increase in the heat capacity of the filter. Increasing the soil capacity provides an increase in the duration of filtration, which increases its performance. The parallel arrangement of the filaments of the filtering layer during the regeneration of the filter forms flow channels of a constant cross section, which contributes to shortening the filter regeneration time by 1.5–2 times and, accordingly, allows 1.5–2 times. time to reduce water consumption for its flushing. Fastening of threads arranged parallel to their length along their length prevents their matching, which ensures the reliability of the filter. . Claims of the Invention - I. A fluid cleaning filter, comprising a housing with inlets and outlets, a movable and fixed perforated partitions and a filtering layer sandwiched between them of separate threads, the ends of KOtopbix fixed on the partitions; YULY with the fact that, in order to improve the efficiency of the filter by increasing the heat capacity of the filter layer and improving its regeneration, the threads of the filter layer are made of variable cross-section along their length, installed in parallel and fastened together. 2. A filter according to claim 1, characterized in that the cross section of the filaments is increased towards the movable perforated partition.
