Abstract

The invention discloses a sieve bend body used for solving the problem of partially replacing sieve surface of a sieve bend. The sieve bend body comprises a sieve frame and a sieve surface fixed on the sieve frame and is characterized in that the sieve surface is formed by combining a plurality of rectangular sieve pieces, transverse sieve holes are evenly distributed in each sieve piece, and the adjacent sieve pieces are clamped. A user can conveniently replace the sieve pieces according to the partial damage conditions of the sieve surface instead of integrally replacing the sieve surface, so that the service life of the sieve surface is prolonged, and production cost is reduced. Due to the clamping structures between the sieve pieces, between the sieve pieces and a beam and between the sieve pieces and the sieve frame, the sieve pieces are fast and easy to replace, assembling and maintaining time for the sieve surface is shortened, and production operation efficiency of the sieve bend is improved.

Description

A kind of sieve bend sieve nest

Technical field

The present invention relates to the sieve bend sieve nest that a kind of screening apparatus, particularly compass screen surface are formed by the clamping of polylith sieve, belong to separation equipment technical field.

Background technology

Sieve bend is the screening plant of curved of a kind of sieve nest, sieve bend be mainly used in coal preparation plant, ore dressing plant to material dewater in advance, desliming, de-mediated operation, classification coal slime recovery etc., have a wide range of applications in industries such as metallurgy, chemical industry, mining industry.The structure of sieve bend is comparatively simple, but treating capacity is very large, and its duty is divided into without pressure feed and pressure feed, no matter which kind of feed-type, the compass screen surface of sieve bend all can be subject to material and impacts frequently and rub, and therefore compass screen surface is very easy to damage, and conventionally uses one or two month to change.Observing the damaged location of sieve bend compass screen surface can find out, compass screen surface state of wear is inconsistent, and concentrated wear is serious, but owing to cannot part being repaired, therefore also can only integral replacing for the compass screen surface of local damage, cause thus the increase of production cost.Existing sieve bend sieve nest comprises compass screen surface and framework, and periphery and the framework of compass screen surface are fixed, and changes compass screen surface operation and comparatively bothers consuming time.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of sieve bend sieve nest of combined type compass screen surface, and the compass screen surface of described sieve nest is formed by the clamping of polylith sieve, can change easily sieve according to compass screen surface local damage situation, extends compass screen surface service life.

For solving the problems of the technologies described above, the technical solution used in the present invention is:

A sieve bend sieve nest for combined type compass screen surface, it comprises screen frame and is fixed on the compass screen surface on screen frame, its key technology: described compass screen surface is combined by polylith sieve, and sieve is rectangle, uniform horizontal sieve aperture in sieve, clamping mutually between adjacent sieve.

The sieve bend sieve nest of combinations thereof formula compass screen surface, the back periphery of described each sieve arranges sieve draw-in groove or sieve Ka Tai, sieve draw-in groove and sieve Ka Tai lay respectively on two limits that sieve faces mutually, sieve Ka Tai or sieve draw-in groove snap-fit in the sieve draw-in groove in a sieve or sieve Ka Tai and another sieve of being adjacent.

The sieve bend sieve nest of combinations thereof formula compass screen surface, uniform crossbeam on described screen frame, crossbeam is circular cross-section, and the back of described each sieve is provided with slotted collar, and slotted collar coupling is connected on crossbeam.

The sieve bend sieve nest of combinations thereof formula compass screen surface, described screen frame periphery arranges screen frame draw-in groove and screen frame Ka Tai, screen frame draw-in groove and screen frame Ka Tai lay respectively on two limits that screen frame faces mutually, be positioned at the sieve draw-in groove of compass screen surface limit portion or sieve Ka Tai respectively with screen frame draw-in groove or screen frame card platform snap-fit.

Adopt the beneficial effect that produces of technique scheme to be: to the present invention is directed to a kind of sieve bend sieve nest with combination compass screen surface that solved sieve bend compass screen surface local replacing Design of Problems.Described sieve nest comprises screen frame and compass screen surface, and wherein compass screen surface is to be combined by the sieve of the mutual clamping of polylith, each sieve with the crossbeam clamping on screen frame is set.Said structure can be easily changed sieve according to compass screen surface local damage situation, and needn't integral replacing compass screen surface, has extended compass screen surface service life, has reduced production cost.Interface arrangment between sieve of the present invention, between sieve and crossbeam, between sieve and screen frame, makes the quick easily row of replacing of sieve, has reduced compass screen surface assembling and maintenance time, has improved the production operational availability of sieve bend.

Detailed description of the invention

below in conjunction with accompanying drawing, the present invention will be described in detail.

Referring to Fig. 1-3, the present invention includes screen frame 1 and be fixed on the compass screen surface 2 on screen frame, the dual-side of screen frame is arc, the crossbeam 4 of uniform circular cross-section on screen frame.For solving damaged compass screen surface local replacing problem, compass screen surface of the present invention adopts combining structure, and compass screen surface 2 is to be combined by several piece sieve 3, and the number of sieve can be determined according to the area of the area of sieve and compass screen surface.

Referring to 4-8, sieve 3 is rectangle, adopts nylon material to make, uniform horizontal sieve aperture in sieve, and the mode by clamping between adjacent sieve connects.At the back of each sieve 3 periphery, sieve draw-in groove 3-2 or sieve card platform 3-1 are set, sieve draw-in groove, sieve Ka Tai lay respectively on two limits that sieve faces mutually.When adjacent sieve clamping, the sieve Ka Tai in the sieve draw-in groove in a sieve or sieve Ka Tai and another sieve or sieve draw-in groove snap-fit, the mutual clamping of several sieves forms compass screen surface 2.Be provided with slotted collar 3-3 at the back of each sieve, slotted collar coupling is connected on crossbeam 4, forms thus and makes fixing between sieve and crossbeam.

Fixing between compass screen surface limit portion and screen frame is also to adopt interface arrangment, and the interface arrangment between this interface arrangment and sieve roughly the same.Referring to Fig. 2, at the periphery of screen frame 1, screen frame draw-in groove 1-2 or screen frame card platform 1-1 are set, screen frame draw-in groove and screen frame Ka Tai lay respectively on two limits that screen frame faces mutually, be positioned at the sieve draw-in groove of compass screen surface limit portion or sieve Ka Tai respectively with screen frame draw-in groove or screen frame card platform snap-fit.

When the present invention uses, get some sieves, by the clamping between the clamping between the clamping between sieve, sieve and crossbeam, compass screen surface and screen frame, be conveniently assembled into sieve nest.After using the serious sieve of a period of time concentrated wear to damage, can conveniently the sieve of damage be replaced by new sieve, needn't integral replacing compass screen surface, thereby greatly reduce production cost, improve the service life of compass screen surface.

To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
