Abstract

The utility model discloses a device separating solid grains which is formed by spirally reeling and welding a metallic screen strip. The plane is arranged in the screen strip and the convex surface is arranged at the outer part of the screen strip; the outer convex surface of the screen strip is welded with a rib strip of a gap of a fixed screen strip; after the reeling and welding forming of the screen, both ends of the screen are connected with sealing rings for enhancing the strength of the metallic screen barrel; both sides of the screen barrel is welded with reinforced joints; the outer part of the screen is provided with a reinforced transverse rib; the material can use the ordinary steel or the alloy steel according to the using condition; the screen barrel is mainly used for separating solid grains in the solid, the liquid, the gas.

Description

Multipurpose particle separation screen drum

The utility model relates to a kind of multipurpose particle separation screen drum, is used in particular for liquid-solid separation, gas solid separation and the solid device that separates.

At the metal separation screen drum of usefulness, adopt woven wire cloth to add skeleton at present more, the perforate of metal letter wall, its shortcoming is that intensity is low, porosity is low, hole is inhomogeneous, service life is short, inferior separating effect.

For addressing this problem, the filter cylinder among the Chinese patent ZL92238131.3, the plane of normally adopting grating outside convex surface welding forms after the little screen drum of lining is cut back warp camber sieve plate open.Because grating is thin, quantity is many, weld bond sealing-off phenomenon in use easily takes place in easy burn-out grating during welding, usually influences separating effect.

The purpose of this utility model is to provide a kind of grating plane in the lining, the multipurpose particle separation sieve letter of the rib new structure outside of grating convex surface and gravity flow screen interspace.The interior moulding process that becomes screen drum is outer moulding process, is easy to that grating, rib are widened, overstriking and at the outside reinforcement of weld horizontal bar of the rib of gravity flow screen interspace, improves the fastness of net tube.Weld with the anchor ring that is connected sealing ring in cross section with rib after the moulding of net tube, utilize again and connect sealing ring and reinforcing joint welding, not only prevent to burn out in the former screen drum forming process grating and sealing-off phenomenon, and improve the compressive resistance of screen drum again and be easy to screen drum and strengthen, diameter can be increased to 6m, tube length can be lengthened to 9m, to adapt to liquid-solid separation under the specific condition, gas solid separation and the solid needs that separate.

Technical solution of the present utility model is, a kind of plane of grating (4) of multipurpose particle separation screen drum of metal grating spiral boxing moulding is in the lining, convex surface outside, protruding or the △ face of grating is welded with the rib (3) of gravity flow screen interspace, the outside of rib is welded with and reinforces horizontal bar (5) formation screen cloth, after the screen cloth moulding burn-on and connect sealing ring (2) in two, connects sealing ring and reinforcing joint (1) to being welded into multipurpose particle separation screen drum.

Advantage of the present utility model is that volume is big, treating capacity is big, intensity is high, gap rate is high, the sieve seam is even, degree of separation is many, precision is high, purposes is wide, long service life, be grain sorting, sewage preliminary treatment, smog dedusting etc., a kind of novel, treating apparatus efficiently is provided.

Description of drawings:

Fig. 1 is the assembly drawing of utility model; Fig. 2 is the transversal profile position of assembly drawing; Fig. 3 is a cross-sectional structure; Fig. 4 is the part section position of rib, grating and reinforcing horizontal bar structure; Fig. 5 is the rib cross section structure; Fig. 6 is grating and reinforces the horizontal bar cross section structure.

Reinforcing joint (1); Connect sealing ring (2); Rib (3); Grating (4); Reinforce horizontal bar (5).

Embodiment:

It is like △ and protruding two kinds that the utility model is selected grating for use, the plane of grating at the lining convex surface outside, spiral equidistantly is wrapped on the cylindrical die, the baseplane width range of grating is 1.0～10mm, the altitude range of grating is 1.5～20mm, and sieve kerf spacing scope is selected arbitrarily between 0.1～50mm.Be welded with the rib of gravity flow screen interspace on the convex surface outside tube, the rib of gravity flow screen interspace is circular and two kinds of batten shapes, and the diameter range of circle is 3～20mm; The thickness range of batten shape is 2～20mm, and width is 3～300mm, and 6～360 of quantity are uniform.The rib of gravity flow screen interspace and grating, the angle that is connected sealing ring, reinforcing joint are 90 °.Be welded with the reinforcing horizontal bar on the rib position of halving, reinforcing horizontal bar is square, and foursquare side size range is 10～100mm, and 1～18 of quantity is uniform.The angle of reinforcing horizontal bar and each rib should keep 90 °, then grating and rib be connected the sealing ring butt welding, its rib keeps 90 ° with the anchor ring angle that is connected sealing ring, can become multipurpose particle separation screen drum by connecting sealing ring and reinforcing joint butt welding after the screen cloth moulding.
