Technical Field

The utility model relates to the technical field of sieve plates, in particular to an arc Johnson sieve screen.

Background

The pressure curved sieve plate is usually used for separation work of a Schchenchen institute, starch slurry, starch milk and slag crust in corn and potato processing, and the conventional pressure curved sieve is formed by vertically welding ribs and strand silk at 90 degrees, has poor segmentation capability, low filtration efficiency and inconvenient cleaning and maintenance.

SUMMERY OF THE UTILITY MODEL

The utility model mainly solves the technical problem of providing the arc-shaped Johnson mesh screen which has good filtering effect on food starchy protein, good segmentation capability and high working efficiency, improves the protein quality and can effectively improve the filtering efficiency by about 20 percent.

In order to solve the technical problems, the utility model adopts a technical scheme that: the arc Johnson mesh screen comprises a screen sheet and side linings arranged at two ends of the screen sheet, wherein the screen sheet comprises a plurality of support ribs welded between the two side linings and a plurality of wedge-shaped strip blocks vertically arranged on the support ribs, the support ribs and the wedge-shaped strip blocks are welded in a mutual melting manner, flow-passing screen seams are formed between the adjacent dry wedge-shaped strip blocks, the intervals of the flow-passing screen seams are equal and are of horn-shaped structures, the support ribs are of arc-shaped structures, a protruding part is integrally formed on the top surface of each support rib facing to the wedge-shaped strip blocks, the protruding part and the wedge-shaped strip blocks are welded in a mutual melting manner, and the bending radian of the screen sheet is 50-70 degrees

In a preferred embodiment of the utility model, the wedge-shaped bar is a V-shaped metal wire, and the tip of the V-shaped metal wire points to the direction of the support rib.

In a preferred embodiment of the utility model, the screen plate has an arc of curvature of 60 °.

In a preferred embodiment of the present invention, the cross section of the support rib is a square or trapezoid structure.

In a preferred embodiment of the present invention, the two ends of the side lining and the screen sheet are welded to each other by fusion

In a preferred embodiment of the present invention, the support ribs are parallel to each other and are disposed at equal intervals.

The utility model has the beneficial effects that: the arc Johnson mesh screen has the advantages that the food starch protein filtering effect is good, the segmentation capability is good, the working efficiency is high, the protein quality is improved, and the filtering efficiency can be effectively improved by about 20%; convenient dismantlement is washd, long service life, saves use cost.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments are briefly introduced below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and other drawings can be obtained by those skilled in the art without inventive efforts, wherein:

FIG. 1 is a schematic representation of an arcuate Johnson screen of the present invention;

FIG. 2 is a tiled view of an arcuate Johnson screen of the present invention;

FIG. 3 is a cross-sectional view A-A of FIG. 1;

fig. 4 is an enlarged view at B in fig. 1.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, an arcuate johnson screen of the present invention comprises: sieve piece 1 and set up in the limit lining 2 at sieve piece both ends, the sieve piece includes that a plurality of brace rods 11 that weld between the two side linings and set up a plurality of wedge strip 12 on the brace rod perpendicularly, brace rod and the mutual fusion welding of wedge strip, it is adjacent form between the dry wedge strip and overflow the crack 3, and every interval that overflows the crack equals and is loudspeaker column structure, the brace rod sets up circular-arc structure, and the top surface of all wedge strip forms a sifter that is the inclined plane, has better segmentation ability, improves filtration efficiency, the brace rod has bellying 13 towards the top surface integrated into one piece of wedge strip orientation, and bellying and the mutual fusion welding of wedge strip, structural strength is high, dismantles and washs the convenience, and long service life has saved use cost.

Specifically, the supporting ribs are parallel to each other and arranged at equal intervals, the bending radian of the screen sheet is 50-70 degrees, preferably, the bending radian of the screen sheet is 60 degrees, the filtering effect is optimal at the moment, the filtering precision is high, in addition, the arc-shaped screen sheet does not need to be bent manually during installation, and the problems that the radian requirement cannot be met and the installation is difficult cannot occur.

The wedge strip piece is "V" style of calligraphy wire, "V" style of calligraphy wire's pointed end is directional the brace rod direction, the cross-section of brace rod are square or trapezium structure, integrated into one piece's bellying and the bottom surface welded connection of wedge on the brace rod, and the brace rod intensity that has the bellying is bigger for the structure of whole sieve piece body is stable more durable, still does not block simultaneously and filters the flow.

In addition, the sieve sheet and the side lining can be made of stainless steel materials, so that the sieve sheet has better acid resistance, alkali resistance and corrosion resistance, and the service life is prolonged.

The arc Johnson mesh screen has the beneficial effects that:

(1) the arc Johnson mesh screen has the advantages that the food starch protein filtering effect is good, the segmentation capability is good, the working efficiency is high, the protein quality is improved, and the filtering efficiency can be effectively improved by about 20%;

(2) the sieve seam evenly distributed between the brace rod, brace rod and the mutual fusion welding of wedge strip piece, structural strength is high, and it is convenient to dismantle and wash, and long service life has saved use cost.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
