Abstract

The invention provides a conical arc blade-type dynamic filter press. The conical arc blade-type dynamic filter press is a continuous filter press using a principle of dynamic filtration, and has a relatively high filtering rate; the solid content of a filter cake can be optimized and freely adjusted; the conical arc blade-type dynamic filter press can directly filter a dilute suspension with the solid content of about 1%; a filtered slurry has a low moisture content; and the production efficiency is high. The conical arc blade-type dynamic filter press comprises a conical barrel, wherein one end of a rotating shaft is fixed by a shaft coupler and is installed inside the conical barrel; the conical barrel is a cone with a wide front part and a narrow back part; conical filter plates are installed on the circumferential surface of the inner wall of the conical barrel at intervals to form multiple stages of filtering chambers; there are 5 stages of filtering chamber; a six-blade disc turbine agitator is installed on the rotating shaft of a first-stage filtering chamber; rotating blade discs are arranged on the rotating shafts of the rest filtering chambers and are separated by the filter plates; the filter plates, the six-blade disc turbine agitator and the rotating blade discs are arranged in a staggered way; circular stirring rod pins are installed on the circumferential surfaces of the top ends of the rotating blade discs; and arc-shaped scraper plates are installed at the two end surfaces of each rotating blade disc.

Description

A kind of tapered arc leaf formula dynamic pressure filter

Technical field

The present invention relates to liquid material and filter field of mechanical technique, be specially a kind of tapered arc leaf formula dynamic pressure filter.

Background technology

Dyestuff in fine chemistry industry, pigment, medicine, synthetic resin etc. and various liquid waste processing, original plate and frame type filter-press is by filter cake controlled filter process, because distortion and the porosity of solid particle in filter cake diminishes, and cause that filtration resistance increases, and filter operation pressure can only be increased to certain limit, because of under identical suspension and filter area, its rate of filtration is slower, and cannot continued operation, the thin suspension that can not be simultaneously 1% left and right for solid content directly filters, discharge filter pulp wet higher containing rate, cannot free adjustment, and also need to consume in a large number washing lotion and time when cleaning, be difficult to the filtration of suitable toxic material and cause environmental pollution.

Summary of the invention

Low for existing plate and frame type filter-press filter efficiency, discharge filter pulp wet higher containing rate, be difficult to the problem that suitable toxic material filters, the invention provides a kind of tapered arc leaf formula dynamic pressure filter, it is for adopting the continuous filter press of dynamic filtration principle, by six leaf disc turbine stirrers in cone cylinder, make material make shearing motion, the effects such as cylinder inward turning rotating disc and arc scraper plate thereof of simultaneously boring improve its shearing force, thereby filtering rate improves, and the solid content of filter cake can be optimized free adjustment, the thin suspension that is 1% left and right to solid content also can directly filter, discharge filter pulp wet low containing rate, production efficiency is high.

Its technical scheme is such: it comprises cone cylinder, one end of rotating shaft is fixed and is installed on by shaft coupling in described cone cylinder, it is characterized in that: described cone cylinder is front wealthy rear narrow taper, described cone cylinder inwall side face interval is equipped with conical filter plate and is formed with it multistage filter chamber, described filter chamber has 5 grades at least, six leaf disc turbine stirrers are installed in the described rotating shaft of first order filter chamber, in the rotating shaft of described filter chambers at different levels, described in interval, filter plate is provided with pivoting leaf dish later, described filter plate, six leaf disc turbine stirrers, the pivoting leaf dish layout that is staggered, described pivoting leaf dish top side face is provided with round stirring rod pin, described pivoting leaf dish both ends of the surface are all equipped with arc scraper plate.

It is further characterized in that: the number of described arc scraper plate has 4 at least;

Described filter plate two end surfaces are provided with intake chute, filter screen is pressed in the two ends of described filter plate by filter frame, filter plate bottom by described cone cylinder internal face is provided with filtrate exit pipe and is placed in outside described cone cylinder cavity, and described cone drum outer wall is provided with the washing mouth of intracavity inter-connection with it;

Charging aperture is arranged at the cone cylinder front end near described six leaf disc turbine stirrers, and discharging opening is placed in the cone cylinder end near described rotating shaft bottom.

A kind of tapered arc leaf formula dynamic pressure filter that the present invention adopts, its beneficial effect is, the high shear force that material first causes during the forced flow by six leaf disc turbine stirrers in cone cylinder, after centrifugal action, again by the round stirring rod pin on pivoting leaf dish in later filter chambers at different levels and the shearing force of arc scraper plate, centrifugal force and mechanism, the particle or the thin layer filter cake that effectively the filter medium surface that is overlying on filter plate periphery outward are temporarily stayed are taken away, thereby play the growth of restriction filter cake, improve the object of filtering rate, intake chute comes together in filter plate bottom by filtrate simultaneously, through filtrate exit pipe, flow out, the suspension under flow regime is along with a motion diameter in cone cylinder reduces and solid content constantly increases, and by thickening continuously, thereby washing and dehydration form thick slurry, and the solid content of filter cake is free adjustment according to circumstances, even if the thin suspension that solid content is 1% left and right also can direct convenience filter, it not only can realize continued operation, discharge filter pulp simultaneously and also there is the lower wet rate that contains, easy to operate, there is good use promotional value and economic benefit.
