Description
Technical field
The utility model relates to a kind of abrasion-proof screen, belongs to industrial screen technology field.
Background technology
At present, abrasion-proof screen is divided into three major types on the market: wear-resisting steel wire woven screen, wear-resisting steel plate punching screen cloth, wear-resisting
Elastomer screen cloth.
Three class screen clothes are respectively arranged with pluses and minuses:
Wear-resisting steel wire woven screen, advantage is that percent opening is high (generally about 55%), and lower ore deposit amount is big, and Ka Kuang is typically 5%
Left and right；Shortcoming is service life the shortest (about 15 days), is by interlacing additionally, due to mesh grid, and aperture is easily deformed,
Mesh grid there is also the slow phenomenon of blanking at screening process.
Wear-resisting steel plate punching screen cloth, generally uses potassium steel material, and advantage is that wearability is strong, impact force proof strong, replacing side
The advantage such as just, because punched-plate uses monoblock steel plate to make, is unlikely to deform in work.Shortcoming is percent opening (about 40%) on the low side, material
Matter is not suitable for abrasive wear, the life-span short (about 40 days), and owing to punching is without tapering, card ore deposit phenomenon is serious (8%).
Elastomer screen cloth, prominent advantage is light weight, wear-resisting, and noise is little, is generally about 70 days service life, shortcoming
Being percent opening low (generally about 32%), Ka Kuang is serious (12%), and production efficiency is low.
Content of the invention
In place of overcoming above-mentioned the deficiencies in the prior art, the utility model provides a kind of abrasion-proof screen device, concentrates and passes
System screen cloth advantage, overcomes its shortcoming, and screening efficiency is high, service life is long.
The utility model is achieved by the following technical solution: a kind of abrasion-proof screen device, and it includes screen cloth main body, sieve
Host's body includes steel plate base layer, and steel plate base layer makes sieve aperture, and steel plate base layer needs to set every a segment distance according to installation
Having the bonding pad not setting sieve aperture, bonding pad makes some connecting holes；The upper surface of described steel plate base layer has wearing layer；Described
The lower surface of steel plate base layer is provided with strengthening rib strip, and strengthening rib strip is fixed on and moves towards cloth below described bonding pad and along bonding pad
Putting, strengthening rib strip outer layer covers has abrasive rubber layer.
Described wearing layer is rich chromium cast iron or chromium carbide or tungsten carbide or associated metal pottery.
The entirety of described steel plate base layer and wearing layer composition uses build-up wear-resistant plate to substitute, and described sieve aperture is at build-up wear-resistant
Plasma cut is used to make on plate.
It is provided with strengthening rib strip described in twice below described bonding pad, between twice strengthening rib strip, leaves gap, formed and institute
State the connector mounting groove that connecting hole adapts.
Described strengthening rib strip uses screw-thread steel or PC rod iron or round steel.
It is connected with the connection support suitable with working equipment below described strengthening rib strip.
The connector suitable with described connecting hole is bolt and nut component.
Described strengthening rib strip is welded in described steel plate base layer.
The beneficial effects of the utility model are: the utility model screening efficiency height, length in service life, easy for installation, sexual valence
Ratio is high.The anti-wear performance of the utility model wearing layer is good；Strengthening rib strip intensity is high, and good toughness does not ruptures during judder；Strengthen
The abrasive rubber layer of rib outer layer covers is flexible, impact resistance, endurance；Three structure sheafs take long benefit on material and performance
Short, organic unity, concentrates conventional screen network optimization point, overcomes its shortcoming, and particularly, the utility model percent opening is high (about 50%),
Higher by about 20% than elastomer screen cloth, Ka Kuang leads and is less than 2%, in length in service life (about 200 days), is 15 times of steel-wire screen, is
2 to 3 times of elastomer screen cloth.
The utility model mainly matches in equipment such as circular vibrating screen, straight line shaker, drum sieve, vibratory sieves, be widely used in mine,
The industries such as water power, building, cement.
