Abstract

The utility model relates to a comb-tooth-shaped combined sieve bottom, belonging to the technical field of dispersing type material sieving. The utility model provides a novel sieve bottom of a vibration sieving device and is characterized in that the sieve bottom is formed by assembling a plurality of comb-tooth-shaped sieve sheets. After the utility model is installed, an inclination degree which adapts to materials to be sieved is formed. The comb-tooth-shaped sieve sheet is composed of a plurality of comb teeth, horn-shaped sieve holes, and a comb back. The comb-tooth-shaped sieve sheet looks like a comb. Comb-tooth-shaped sieve holes form bar-shaped horn holes the front part of which is large and the back part of which is small. The utility model has the advantages that the utility model can eliminate the blockage of the sieve holes, and the utility model can conveniently replace the sieve bottom partially which is easy to damage. The purposes of increasing sieving efficiency and reducing use expense are achieved.

Description

The comb teeth shape combination sieve end

The utility model relates to a kind of comb teeth shape combination sieve end, belongs to bulk material material sieving technology field, be a kind of novel sieve of vibrosieve equipment at the bottom of.

Vibrosieve equipment is widely used in the classification of industry bulk materials such as mine, metallurgy, chemical industry or screens out powder.The sieve end is the crucial accessory of screening plant, also is consumable accessory.In vibration frequency and amplitude one timing, the screening efficiency of screening plant depends on the quality of sieving the end.At the bottom of mesh screen arranged at the bottom of the sieve that adopts at present extensively, the bar shaped sieve end, " people " font sieve end, the tabular punching sieve end, for increasing the service life, various wear-resistant materials have been adopted at these sieve ends.But they exist two big defectives jointly, and first sieve aperture easily stops up, and screening efficiency is reduced, and it two is that blanking impact place is fragile, and other most of sieve life-spans end are longer, change together at the bottom of needing whole sieve when changing.

The purpose of this utility model provide a kind of can reduce or eliminate the sieve pore blockade phenomenon and can change the sieve of fragile part easily at the bottom of spare part.

The object of the present invention is achieved like this: the described comb teeth shape combination sieve end,, it is formed (accompanying drawing 3) by comb teeth shape sieve sheet and vibratory sieve framework.Comb teeth shape sieve sheet (accompanying drawing 1) is made up of several broach, tubaeform sieve aperture and a comb back of the body, exactly likes a comb.The sieve aperture of comb teeth shape sieve sheet is an irregularly-shaped hole, is the bellmouth orifice (accompanying drawing 1) of pre-large post-small bar shaped, and the size in hole and bar length are according to the granule size that is sized the material requirement is decided.The sieve end is to be assembled by some comb teeth shape sieve sheets, and first comb teeth shape sieve sheet is installed in vibratory sieve foremost, and the front end of second comb teeth shape sieve sheet is pushed down the comb back of the body of first comb teeth shape sieve sheet, and all the other install (accompanying drawing 2) successively.After the comb teeth shape combination sieve end installs a gradient (accompanying drawing 3) that is adapted to be sized material is arranged.

The utility model is compared the advantage that it is outstanding with the existing sieve end: the one, can avoid sieve pore blockade, and can improve screening efficiency 50～60%, the 2nd, but local replacing sieves the end, can save human and material resources, financial resources and shortening and change the time, boosts productivity.

Accompanying drawing:

Accompanying drawing 1: comb teeth shape sieve sheet

Accompanying drawing 2: comb teeth shape combination sieve bottom plan view

The A-A profile of accompanying drawing 3: Fig. 2

The explanation of accompanying drawing drawing: (1) is the comb back of the body among Fig. 1, and (2) are tubaeform sieve apertures, and (3) are broach, and φ is two bolts hole that usefulness is installed.(4) are the vibratory sieve frameworks among Fig. 3, and (5) are bolts.(6)～(n) are comb teeth shape sieve sheets among Fig. 2, Fig. 3.

The utility model embodiment accompanying drawings is as follows:

With reference to accompanying

drawing

1,2,3, accompanying drawing 1 interdigitated electrode structure sieve sheet processes through cut, dash, brill etc. by the figure paper size.The accompanying drawing 2 comb teeth shapes combination sieve end is to be assembled by some comb teeth shape sieve sheets.At first first comb teeth shape sieve sheet (6) is installed in vibratory sieve framework (4) foremost, broach (3) front end of second comb teeth shape sieve sheet (7) is pushed down on the comb back of the body (3) of first comb teeth shape sieve sheet (6), and with bolt (5) comb teeth shape is sieved sheet and be screwed in vibratory sieve framework (4), all the other are installed successively and the whole vibratory sieve sieve end are filled.A gradient that is adapted to be sized material is arranged after the installation.
