Abstract
The utility model discloses a magnetic modular polyurethane guard plate which comprises an internal layer reinforcement steel plate; a plurality of through holes are formed in the internal layer reinforcement steel plate with equal interval; a plurality of high-magnetism magnets are arranged under the internal layer reinforcement steel plate with equal interval; and the internal layer reinforcement steel plate and the plurality of high-magnetism magnets are formed into a whole which is wrapped by external layer polyurethane basic bodies. The magnetic modular polyurethane guard plate has the advantages of being simple and reasonable in structure, enabling energy consumption of a device to be effectively reduced after utilization, being good in performances of high abrasion resistance and impact resistance, convenient to install, low in noise, easy to install, not easy to leak slurry and corrosion resistant and reducing abrasion of the device.
Description
Technical field
The utility model relates to a kind of backplate, is specially a kind of magnetic module formula polyurethane backplate.
Background technology
In the screening process of materials such as ore and coal, the shortcoming that always has high energy consumption, poor efficiency, high pollution (dust pollution and noise pollution), pollute in order to raise the efficiency, cut down the consumption of energy, to reduce, through scientific research personnel's continuous effort, the research of some equipment has obtained certain progress.With regard to most popular ball mill, vibrating mill and vibrating scalper, the quality of the backplate material material of interior dress and outer dress is considered to one of key that improves abrasive dust and screening efficiency always.The backplate that is applied at present in the actual production has multiple class and material as metal casing, ceramic backplate and rubber backplate etc.But because the restriction of material itself, in use simultaneously also there are a lot of defectives in these liner plates: for example metal backing is heavier, the machine utilization height, the installing/dismounting complexity, it is poor that acidproof and electrochemically resistant is learned corrosivity, and noise is big, and can only be used for grinding to sieve not being afraid of the irony contaminated material; In a single day and ceramic lining plate is subjected to the restriction of production technology and cost, in use occurs breaking, just must all change, and noise is big, and the material effective rate of utilization is very low, the life-span weak point; Then there is easily aging, tear resistance difference in rubber lining and shortcoming such as wear no resistance, and has added the aromatic oil carcinogen in the material again, can slowly release toxic gas in use.Especially under the impact of high speed hard ware material, processing temperature raises, and damage speed is accelerated greatly.Though the backplate of a lot of polyurethane is also arranged now, and two ends all are to add screw with steel plate to fix, not only installation and removal are inconvenient, and bring certain degree of difficulty to production, also increased cost simultaneously.
The utility model content
The purpose of this utility model provides a kind of magnetic module formula polyurethane backplate, comparatively heavy to solve metal casing traditional in the prior art, the installing/dismounting complexity, it is poor that acidproof and electrochemically resistant is learned corrosivity, noise is big, and can only be used for grinding the material that the irony pollution is not afraid of in screening; Pottery backplate noise is big, and the material effective rate of utilization is very low, and the life-span is short; Then there is easy aging, tear resistance difference in rubber lining and the problem of shortcoming such as wear no resistance.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of magnetic module formula polyurethane backplate, it is characterized in that: include internal layer and strengthen steel plate, described internal layer strengthens the steel plate equal intervals and is distributed with a plurality of through holes, described internal layer strengthens the steel plate below and equidistantly is distributed with the high-strength magnetic magnet of polylith, and described internal layer strengthens steel plate and the high-strength magnetic magnet of polylith constitutes an integral body and externally is coated with the outer polyurethane matrix.
Described a kind of magnetic module formula polyurethane backplate is characterized in that: be distributed with a plurality of locating holes around the described outer polyurethane matrix, described locating hole passes internal layer and strengthens steel plate.
The beneficial effects of the utility model are:
1, low power consuming.The density of polyurethane composite lining board of grinder than steel liner plate and ceramic lining plate be much smaller many, the urethane plate is installed has been reduced the weight of screen(ing) machine integral body dramatically, thereby reduced the load of motor, saved electric energy, just reduced production cost.
2, high abrasion, shock-resistant.General manganese steel backplate on average operates as 5300-6100 hour, the average running of rubber 7800-13000 hour service life.And the abrasion of polyurethane be we can say more wear-resisting than rubber backplate well below rubber.Liner plate adopts special formulation, and through vulcanizing treatment, its anti-wear performance promotes significantly, can also can artificially add the filler of the high abrasion of some different hardness according to client's demand.Simultaneously, the polyurethane backplate has high resistance to impact.The fierceness bump of manganese steel backplate and rubber backplate invar ball cracked phenomenon is arranged to some extent, but the polyurethane backplate is with its intrinsic elastic buffer; basically stopped cracked phenomenon; thereby reduced maintenance cost, saved fault power time, guaranteed the ordinary production order of enterprise.
3, low noise.In the production process of mine, two kinds of occupational disease killers are arranged now: the one, dust pollution, the one, noise pollution.The grinding machine of manganese is installed, and steel ball and manganese directly clash into during running, and noise is loud and sonorous ear-piercing, and noise is about 110dB, directly endangers the healthy of employee.And behind the repacking polyurethane backplate, ore has just reduced noise with the polyurethane collision itself with high toughness, polyurethane itself has certain soundproof effect in addition, noise reduces 20dB at least, working environment has obtained improving greatly, also be bound to excite employee's work incentive, improved the productivity effect of enterprise indirectly.
4, easily install.The manganese that the polyurethane backplate compares is in light weight, does not need special erecting tools such as crane during installation.According to the rational modular magnetic polyurethane of customer demand designed size backplate, as long as the several people just can be easy to installation, avoided weighing wounded the generation of accident such as trick simultaneously, thereby greatly reduced downtime, improved the efficiency of operation of enterprises.
5, spillage not.The modular magnetic polyurethane backplate parts that design and produce have ensured the sealing property of grinding machine, have stopped the spillage phenomenon.
6, corrosion-resistant.Chemical reaction can take place with acid, alkali, salt etc. in metal, has accelerated the wearing and tearing of liner plate; Polyurethane has certain antiacid alkali, electrochemically resistant is learned corrosion resistance and oil resistivity, and is water insoluble, thereby prolonged the service life of backplate effectively.
7, save steel ball.Border work measuring and calculating factually, the firm liner plate of raw ore manganese per ton consumes 1.16 kilograms of steel balls.By 100,000 tons of calculating of annual output raw ore, about 15 tons of year saving steel ball, expense is considerable.
8, reduce equipment attrition.This is that to be lower than the quality of manganese directly related with the quality of polyurethane backplate.Because low load, the gear wear of complete machine and gearbox wearing and tearing all effectively reduce, and the motor feels hot, and coefficient reduces, and the line bag is difficult for aging, thereby obviously prolong complete machine service life.
