Abstract
The utility model discloses a back washing filter screen for screw extrusion. The back washing filter screen comprises a main keel, a reinforcing ring and a filter strip, wherein the main keel comprises an upper annular keel and a lower annular keel; four linear keels are uniformly distributed between the upper annular keel and the lower annular keel; the upper end of the linear keel is fixed on the upper annular keel, and the lower end of the linear keel is fixed on the lower annular keel; the inner side of the linear keel is provided with the reinforcing ring; the inner side of the reinforcing ring is vertically provided with the filter strip; the upper end and lower end of the filter strip are respectively fixed on the upper annular keel and the lower annular keel. By adopting the technical scheme, the back washing filter screen disclosed by the utility model is firm and durable by adopting a stainless steel sectional material and being reasonable in structural design. The back washing filter screen disclosed by the utility model has the advantages that the cross section of the filter strip is in a trapezoid shape and the trapezoid structure is favorable for back washing, thereby being difficult to block and high in filter efficiency.
Description
Technical field
The utility model relates to a kind of reverse flushing filter screen for screw extrusion.
Background technology
The preparation method of existing Chinese edible oil is divided squeezing (physics) and is leached (chemistry) two kinds, leaching is by a kind of chemical substance oil immersion out, oil productivity is higher than squeezing mode, but by a kind of chemical substance of Leaching way the inside, eat forever and all can put aside in vivo, also arrange decades and do not go out.Tradition squeezing or a kind of healthier method, but tradition squeeze filter screen and often stop up, and it often holds infringement due to screw extrusion mode.
Utility model content
For solving the problems of the technologies described above, we have proposed a kind of backwash that is easy to, and stainless steel is firm durable, do not allow the flimsy reverse flushing filter screen for screw extrusion.
For achieving the above object, the technical solution of the utility model is as follows:
For a reverse flushing filter screen for screw extrusion, comprise main joist, stiffening ring and filtering strap; Described main joist comprises annular keel and lower annular keel, uniform four straight line keel between described annular keel and lower annular keel, and the upper end of described straight line keel is fixed on described annular keel, and its lower end is fixed on lower annular keel; Described straight line keel inner side is provided with described stiffening ring; Described stiffening ring inboard, upright is provided with described filtering strap, and the two ends up and down of described filtering strap are separately fixed on described annular keel and lower annular keel.
Preferably, described main joist also comprises middle annular keel, and described middle annular keel are located between described annular keel and lower annular keel, and it is fixed on described straight line keel.
Preferably, the cross section of described filtering strap is trapezoidal.
Preferably, the described employing of the reverse flushing filter screen for screw extrusion material is stainless steel.
By technique scheme, the utility model is by adopting stainless section bar, reasonable in design, thereby it is sturdy and durable; The cross section of described filtering strap is trapezoidal, and its trapezium structure is beneficial to backwash, thereby its difficult obstruction, and filter efficiency is high.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic top plan view of the disclosed a kind of reverse flushing filter screen for screw extrusion of the utility model embodiment;
Fig. 2 is that Fig. 1 is along the generalized section of A-A direction.
Numeral and the represented corresponding component title of letter in figure:
1. go up 3. times annular keel 4. straight line keel 5. stiffening ring 6. filtering straps of annular keel in annular keel 2.
The specific embodiment
Below in conjunction with embodiment and the specific embodiment, the utility model is described in further detail.
The utility model provides a kind of reverse flushing filter screen for screw extrusion, and its operation principle is: the utility model is by adopting stainless section bar, reasonable in design, thereby it is sturdy and durable; The cross section of described filtering strap is trapezoidal, and its trapezium structure is beneficial to backwash, thereby its difficult obstruction, and filter efficiency is high.
Embodiment
As shown in Figure 1 and Figure 2, a kind of reverse flushing filter screen for screw extrusion, comprises main joist, stiffening ring and filtering strap; Described main joist comprises annular keel 1 and lower annular keel 3, uniform four straight line keel 4 between described annular keel 1 and lower annular keel 3, and the upper end of described straight line keel 4 is fixed on described annular keel 1, and its lower end is fixed on lower annular keel 3; Described straight line keel 4 inner sides are provided with described stiffening ring 5; Described stiffening ring 5 inboard, upright are provided with described filtering strap 6, and the two ends up and down of described filtering strap 6 are separately fixed on described annular keel 1 and lower annular keel 3; Described main joist also comprises middle annular keel 2, and described middle annular keel 2 are located between described annular keel 1 and lower annular keel 3, and it is fixed on described straight line keel 4; The cross section of described filtering strap 6 is trapezoidal; It is stainless steel that the described reverse flushing filter screen for screw extrusion adopts material.
By technique scheme, the utility model is by adopting stainless section bar, reasonable in design, thereby it is sturdy and durable; The cross section of described filtering strap 6 is trapezoidal, and its trapezium structure is beneficial to backwash, thereby its difficult obstruction, and filter efficiency is high.
Above-described is only a kind of reverse flushing filter screen preferred embodiment for screw extrusion of the present utility model; should be understood that; for the person of ordinary skill of the art; do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
