Abstract
The utility model relates to a high-strength composite mesh screen which belongs to the technical field of screening devices and is used for solving the problems that the strength of an ordinary mesh screen is low, and the service life is short. The utility model is composed of an upper screen and a supporting screen. The utility model has the improvement that the upper screen is a metal wire screen, and the supporting screen is a polyurethane supporting screen; the polyurethane supporting screen is positioned below the metal screen and forms a lattice shape of longitudinal and transverse intersection, and longitudinal and transverse strips thereof are all made of wire rope cores and polyurethane surface layers. With the improvement, the utility model is different from the good performance of an ordinary metal mesh screen. The utility model has high strength, rigidity and carrying capacity and can effectively decrease the vibrating noise and extend the service life of the mesh screen. The utility model can be made into screening device with various shapes, and is particularly suitable for electromagnetic exciting high-frequency vibration mesh screens. The utility model can be used for the operation of screening, filtration, dehydration, slime separation, etc. in multiple industries.
Description
Technical field
The utility model relates to a kind of solid separation equipment, is a kind of screen cloth that is used for vibration sieve specifically, belongs to the screening plant technical field.
Background technology
The screening material is to use operating type very widely in industries such as coal, metallurgy, cement, pottery, building materials, chemical industry.A kind of vibration sieve by the electro-magnetic exciting force vibration screen is used very general.The screen cloth of vibration sieve separates with screen box, and exciting force directly acts on screen cloth, has reduced to join the quantity and the weight of the parts that shake, and power consumption reduces, and the life-span of equipment is longer relatively.Usually electromagnetic exciting can produce very high vibration frequency, makes vibration sieve have stronger classifying capability.In the prior art, the screen cloth of vibration sieve is many to be formed by metal wire knitted, the vibrating elements high-frequency impacts screen cloth in screening process, the screen cloth long-term work is under the alternate stress effect, fatigue damage is given birth to by the side of being easy to, and also need bear very big pressure for screen clothes such as sieving bigger material of proportion such as Iron Ore Powder, in addition, vibrating elements directly contacts with woven wire, can produce bigger noise pollution.It is more flimsy parts in the screen(ing) machine that above-mentioned factor makes screen cloth, and frequently changing screen cloth not only increases production cost, also influences production efficiency because of the increase of maintenance of equipment time.
Summary of the invention
The utility model is used to overcome the defective of prior art and a kind of compound screen cloth of high strength with polyurethane holder net, long service life is provided.
The alleged problem of the utility model is solved by following technical scheme:
The compound screen cloth of a kind of high strength, form by online and holder net, its special feature is: described online is that woven wire, holder net are polyurethane holder net, described polyurethane holder net is close under the woven wire, the longitude and latitude bar that constitutes polyurethane holder net is the trellis that intersects in length and breadth, and described longitude and latitude bar is made of Steel cord and polyurethane skin layer.
The compound screen cloth of above-mentioned high strength, described online are the double-level-metal silk screen, are fixed as one by the vulcanized rubber bar between the double-level-metal silk screen, and the vulcanized rubber bar is trellis and evenly distributes.
The compound screen cloth of above-mentioned high strength, described online is the single-layer metal silk screen, uniform trellis vulcanized rubber bar on the woven wire.
The compound screen cloth of above-mentioned high strength, the mesh of described polyurethane holder net is a rectangle, its size dimension is 3～10 millimeters.
The compound screen cloth of above-mentioned high strength, 200～300 millimeters of described vulcanized rubber stripe pitch, the vulcanized rubber bar is wide 5～30 millimeters, thick 0.3～10 millimeter.
The problem that the utility model is fragile at the vibration sieve screen cloth, service life is short has been carried out following improvement: abrasion resistant polyurethane holder net is set, in order to directly to bear impacting of exciting parts in the woven wire bottom 1.; 2. the vulcanized rubber bar that trellis distributes is set, on the woven wire in order to improve the intensity of woven wire.The premium properties that the utility model is different from the common metal screen cloth is given in above-mentioned improvement, makes it have higher intensity, rigidity and bearing capacity, and can effectively reduce vibrating noise, improves screen cloth service life.The utility model can be made into the screening plant of different shape, is particularly useful on the high frequency vibrating screen of electromagnetic exciting, can be widely used in the operations such as screening in the conglomerate, filtration, dehydration, desliming.

Number in the figure is expressed as follows: 1. woven wire; 2. polyurethane holder net; 3. double-level-metal silk screen; 4. vulcanized rubber bar; 5. Steel cord; 6. polyurethane top layer; 7. single-layer metal silk screen.
The specific embodiment
Referring to Fig. 1,2, the utility model is made up of online and holder net, and surfing the Net is woven wire 1, directly contacts with material, and the holder net is a polyurethane holder net 2, is positioned under the woven wire directly to contact with the exciting element.Referring to Fig. 3, Fig. 4, polyurethane holder net is the trellis that intersects in length and breadth, and its longitude and latitude bar constitutes by Steel cord 5 and polyurethane skin layer 6, and its mesh is a rectangle, and size dimension is 3～10 millimeters, and mesh also can adopt square or other geometry.
Referring to Fig. 5～Fig. 8, look the demand of screening material, online can be the double-level-metal silk screen 3 or the crin single-layer metal silk screen 7 of filament, and vulcanized rubber bar 4 is set on the wire side of woven wire, and the vulcanized rubber bar is trellis and evenly distributes, 200～300 millimeters of spacings.Can play the effect of reinforcement for single-layer metal silk screen vulcanized rubber bar, to the double-level-metal silk screen, the vulcanized rubber bar be reinforcement be again binding agent, two layers of mesh can be fixed as one securely.
Intensity of the present utility model, rigidity, bearing capacity, service life all apparently higher than common screen cloth, are very suitable for high frequency vibrating screen.Woven wire tensioning in upper strata is laid during use, seal with screen box, lower floor's Steel cord polyurethane holder net directly contacts with exciting device, polyurethane skin layer has good wear resistance, not only can prolong screen cloth service life, but also can reduce noise, the Steel cord of polyurethane holder net then can play the effect that improves strength and stiffness.
