Description

Continuous viscose rayon-filtering machine

The present invention is one and is used for the viscose glue continuous filter that the staple fibre spinning solution filters, it has an airtight overpressure resistant barrel, glue-feeder is arranged at the cylindrical shell bottom, gum outlet is arranged at top, in the tube revolution backwash arm that filtering surface is carried out continuous backwash is housed, revolution backwash arm links to each other with hollow drive shaft and constitutes backwash glue passage.

A kind of known continuous filter is arranged, can guarantee effective separation of viscose glue impurity.But the major part of this filter volume is occupied by the backwash arm, and filter area is limited, and need give first filtering rubber and mechanical admixture.In addition, when wearing and tearing, backwash arm suction nozzle need shut down adjustment.

Task of the present invention provides a kind of big filter amount viscose glue continuous filter, and this filter has the multiple filtration surface in limited chamber space.

Another task of the present invention is will filter and give the filtration two procedures to finish in the lump in filter.Further task of the present invention is that the wearing and tearing of backwash arm suction nozzle can compensate in running automatically.

Its solution is: filter drum is two-sided, and filter drum that several diameters are different and plectane are combined into the multiple filtration assembly, and the stud of filter drum inside is divided into the several separate filter element with filter assemblies; The plane rotation backwash arm that independent filter element is carried out the order backwash is arranged at the distribution plate bottom.

Between the plectane of filter and distribution plate,, give filter screen and form by filter screen and protecting wire net with having the rubber seal that gives filter screen; Hollow drive shaft is that lead key connects, and is equipped with and gives tight spring.

Filter of the present invention is compared with known filter, compact conformation, and the unit filter capacity can improve several times, saves the auxiliary filter plant that gives, the filtration short circuit of having avoided the suction nozzle wearing and tearing to cause.The plane suction nozzle is reliable simultaneously, and it is low to make required precision.
