Abstract

The utility model relates to a liquid filter, in particular to a laminated disc filter and a filter element thereof. The filter element is formed by laminating annular filter plates, two annular surfaces of each filter plate are both equipped with intensive grooves which are spirally radial, and spirally radial directions of the grooves on the two surfaces are opposite. After the filters are laminated under external force, edges of adjacent grooves on two adjacent surfaces are staggered to form a plurality of intersected joints, and a plurality of fine slit cavities are formed among the grooves, thereby realizing filtering function. The laminated disc filter utilizes the filter element. The laminated disc filter has excellent liquid filtering effect and can be widely applied to industriessuch as food, drinks, machinery, metallurgy, chemical engineering and the like.

Description

Lamination disc filter and filter core thereof

Technical field

The utility model relates to a kind of filter, especially relates to a kind of lamination disc filter and filter core thereof.

Background technology

The lamination disc filter is compared with traditional sand filtration formula filter, fabric filter, net filter formula filter and other multimedium formula filters, have that filter effect is better, control mode is various, automaticity is high, precision is high and almost Maintenance free, change parts, therefore plurality of advantages such as long service life are widely used in such as numerous industry fields such as food and drink, machinery, metallurgy, chemical industry.In the lamination disc filter, stacked filter core is one of its critical component, and the filter capacity of filter core has determined the using value of filter as a most important aspect.Stacked filter core is laminated by filter and constitutes, thereby filter and filter laminate that the back forms interstitial cavities between it and contact point produces filtering function, so the design of ditch slot texture directly has influence on the filtering efficiency of filter on the filter, and this is very crucial.

The utility model content

The utility model provides a kind of filter core that is used for laminated filter, and a kind of lamination disc filter of using this filter core, and this filter has excellent filter effect.

The technical solution adopted in the utility model is: a kind of filter core that is used for laminated filter, this filter core is laminated by the annular filter sheet and constitutes, on two ring surfaces of described filter, be provided with intensive, the groove of divergent shape in the shape of a spiral, and the direction that the spiral that groove presented on two faces is dispersed is opposite; After filter laminates under external force, the numerous intersection contacts of the staggered formation of groove seamed edge on adjacent two faces, groove and groove form numerous small spaces chamber, thereby produce filtering function.

The filter of described formation filter core is made by engineering plastics.

A kind of lamination disc filter includes filter body shell, inlet pipeline, outlet pipeline, blowoff line and opens and closes valve accordingly, is provided with aforesaid filter core in the filter body shell.

The beneficial effects of the utility model are: this lamination disc filter has the unique stacked filter core of design, thereby has the excellent liquid filter effect, can be widely used in such as numerous industry fields such as food and drink, machinery, metallurgy, chemical industry.

The specific embodiment

A kind of filter core that is used for laminated filter, this filter core is laminated by annular filter sheet 51 and constitutes, as shown in Figure 2, on two ring surfaces of filter 51, be provided with intensive, the groove of divergent shape in the shape of a spiral, and the direction that the spiral that groove presented on two faces is dispersed is opposite; After filter 51 laminates under external force, the numerous intersection contacts of the staggered formation of groove seamed edge on adjacent two faces, groove and groove form numerous small spaces chamber, thereby produce filtering function.

Filter 51 is made by engineering plastics.

As shown in Figure 1, a kind of lamination disc filter includes filter body shell 1, inlet pipeline 2, outlet pipeline 3, blowoff line 4 and opens and closes valve accordingly, is provided with aforesaid filter core 5 in filter body shell 1.

Filter is after laminating, and the direction that the groove spiral on the adjacent surface is dispersed is opposite, the numerous intersection contacts of the then staggered formation of groove seamed edge, and groove and groove form numerous interstitial cavities.Because groove is diverging in the shape of a spiral, therefore from the outer ring to the inner ring, interstitial cavities is more and more littler, and groove seamed edge intersection contact is more and more closeer.During filtration, current inwardly enclose formation from the filter outer ring that respectively laminates passage infiltrates, and turbulent flow takes place in the small spaces chamber between the pressing filter, and impurity is then by numerous intersection contact interceptions in the water.

The impurity that is mingled with when between filter more for a long time, filter will start the self-cleaning program automatically, control valve, release is to the pressure force of filter, and the recoil water flow valve of opening filter core central authorities carries out backwash to filter, recover after finishing the pressure force of filter is made it the superimposed clean filter core that becomes again, enter the filtration duty again behind the adjustment valve state.Whole filter process is quick, efficient, reliable.
