Abstract

The utility model provides a high anti-impact steel reinforced polyurethane sieve plate. The sieve plate is designed by the utility model into a polyurethane abrasion resistant layer 4, steel reinforced layer 3 and anti-tension erosion resistant layer 5 which are formed into integration structure through a full-coating bonding layer 6 and self-rivet structure 2. Sieve meshes 1 all are have certain conicity and in the arrangement of Chinese 'pin'. The sieve plate has the advantages of simple structure, light weight, low noise, high sieving efficiency, wear resistance, corrosion resistance, good rigidity of integration, high performances of impact resistance and tear resistance and long service life. The utility model is particularly suitable for the sieving of the materials of large volume.

Description

High anti-impact steel reinforced polyurethane sieve

The utility model relates to a kind of vibratory sieve or the novel sieve plate of drum sieve.Be mainly used in classification, de-mediated or the dehydration of material.

At present, the sieve plate that domestic vibratory sieve or drum sieve are used mostly is punching steel plate, stainless steel strip net or common metal net greatly, and it is not wear-resisting, not anti-corrosion, the life-span is short, weight is big, noise is high ...Part R﹠D institution and producer have developed polyurethane sieve plate, rubber sieve plate or plastics sieve plate for this reason.Though in light weight, the characteristics such as noise is little, good springiness, erosion resistant of this class sieve plate tool, but still have that intensity is low, poor rigidity, shock resistance be poor, easily elongation strain produces ore deposit pocket or fatigue and drawback such as tears.

The purpose of this utility model promptly is a kind of novel high-impact steel plate reinforcement polyurethane sieve plate that proposes at above problem.Be primarily characterized in that this sieve plate is made up of polyurethane compass screen surface wearing layer, steel plate reinforcement layer and the anti-anticorrosive coat of opening; Sieve aperture is " product " font and arranges and the tool certain taper.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 high-impact steel plate reinforcement polyurethane sieve plate schematic diagram.

Fig. 2 is that Figure 1A-A is to cross-sectional view.

Fig. 3 steel plate reinforcement layer sectional schematic diagram.

Fig. 4 curved circular shaft screen sieve plate section structure schematic diagram.

1, is the tapering sieve aperture that " product " font is arranged

2, wear the riveting structure certainly

3, steel plate reinforcement layer

4, polyurethane compass screen surface wearing layer

5, the anti-anticorrosive coat of opening

6, coat tack coat entirely

7, interlayer is worn rivet hole

8, the female hole of sieve aperture

The concrete implementation procedure of the utility model is: first, selecting specification suitable thick is steel plate about 2～5mm, press the sieve aperture distribution and process the female hole 8 of sieve aperture of respective numbers than big about 15% the specification of required sieve aperture specification, wear rivet hole 7 at the interlayer that reaches processing suitable number on the steel plate periphery muscle band between female hole 8, will be bent into arc to the cylinder sieve plate) thereby form steel plate reinforcement layer 3(; The second, insert suitable mould after steel plate reinforcement layer 3 being carried out the PROCESS FOR TREATMENT of tack coat 6, utilize the casting type polyurethane forming technology with the sieve plate sulfidization molding that the utility model proposes.

Select for use the polyurethane that wearability is good, resilience is high to do wearing layer 4 on the utility model structural design; Steel plate is done strengthening course 3; Selecting for use the high polyurethane of tensile strength to be the anti-anticorrosive coat 5(of opening also can be the polyurethane material of same performance); Wearing layer 4 and the anti-anticorrosive coat 5 of opening are by full clad type tack coat 6 with wear riveting structure 2 certainly and steel plate reinforcement layer 3 all is coated on the sieve plate inner bottom part forms overall structure; The equal tool certain taper of sieve aperture of the present utility model and be " product " font and arrange.

The utility model has solved that nonmetal sieve plate intensity is low, the technical barrier of shock resistance difference. Have following technical characterstic and result of use:

1, in light weight, the running energy consumption low;

2, noise is little, environmental benefit good;

3, the screen-penetrating performance energy is good, screening efficiency is high;

4, integral rigidity height, shock resistance, tear-proof, wear-resisting, anti-corrosion, long service life are specially adapted to the long-pending material screening of big grain.

Claims

1, a kind of high-impact steel plate reinforcement polyurethane sieve plate is characterized in that it is designed to the wear-resisting layer 4 of polyurethane, steel plate reinforcement layer 3 and the anti-anticorrosive coat 5 of opening with sieve plate; Form overall structure by the full clad type tack coat 6 and the dual measure of wearing riveting structure 2 certainly between the three.

2, sieve plate according to claim 1, the shape that it is characterized in that this sieve plate can be that flat oscillating screen plate also can be a curved circular shaft screen plate.

3, sieve plate according to claim 1 is characterized in that the sieve aperture 1 of this sieve plate all is certain taper and is the arrangement of " product " font.

4, sieve plate according to claim 1 is characterized in that wearing layer 4 and the anti-anticorrosive coat 5 of opening can be that the polyurethane of two kinds of different performances also can be the polyurethane with performance.
