Description

The box-like disintegrating machine of a kind of novel tooth form rank groups

Technical field

The utility model relates to a kind of disintegrating machine, and the box-like disintegrating machine of specifically a kind of novel tooth form rank groups belongs to field of cracking machine.

Background technology

At present; The disintegrating apparatus major part of industry materials such as China mine, electric power, colliery, chemical industry, building materials is products (double-geared roller crusher, ring hammer, jaw formula, counterattack etc.) of 50～sixties, exist that ageing equipment, particle size after cracking transfinite, power consumption is big, production efficiency is low, fault is many, service life is short, can not the strict guarantee product granularity etc. problem.

Graded crushing is a kind of novel crushing technology that the eighties begins worldwide to occur; Become the dominant technology trend of coal crushing at present; Its core characteristics are: guarantee granularity requirements: pulverize low excessively: the pan feeding of forming for different dynamics carries out selective crushing; The material that meets granularity requirements directly passes through, only to carrying out fragmentation greater than the material that requires granularity, product all satisfy product requirement.Remove in addition, obvious advantage such as Sizing Crusher has also that disposal ability is big, the complete machine height is low, equipment dependability is high, friction, noise are low can the simplification system have saving equipment and capital expenditure after using this equipment.

The utility model content

In order to address the above problem, the utility model has designed the box-like disintegrating machine of a kind of novel tooth form rank groups, this disintegrating machine collection coarse crushing, in the Trinity broken, in small, broken bits, tooth surface shape has forms such as bachelor, grooved roller, discaling roll, original text shape pick, production efficiency is high.

The technical scheme of the utility model is:

The box-like disintegrating machine of a kind of novel tooth form rank groups comprises frame, charging cover plate, and the discaling roll that is installed on the frame and is driven by motor and belt pulley;

Discaling roll has different profiles of tooth, and novel tooth form screw arrangement such as wolf's fang tooth, conical tooth and original text shape pick are on discaling roll, and two roller relative motions are like the diagrid of rotation; To go less than the material sieve of product granularity; Bulk materials is carried out fragmentation, avoided getting into the broken defective of material doping of disintegrating machine, have the double effects of fragmentation, screening; Can accomplish fragmentation, screening operation separately within the specific limits, need not to be equipped with screening plant.

Be connected with the secured adjusted device on the bearing of discaling roll, adopt the fixed center distance, can require convenient and swift adjustment fixed center distance according to product granularity; Further, said secured adjusted device is the secured adjusted bolt;

Hydraulic pressure is installed on the discaling roll makes a concession protective device automatically, prevent that nonferromagnetic alloy block, admant piece are to the harm to the discaling roll operate as normal of the destruction of discaling roll and wooden unit and flexible article;

The foreign material cleaning plant is housed on the frame, strong to the adaptability of adhesional wetting material;

Be furnished with the current overload protection protection unit on the motor,, phenomenon after-current increases such as stall occur, report to the police and shutdown system the complete machine monitoring;

Entire equipment is provided with and adopts the lubricating arrangement of concentrating the multi point lubricating mode, guarantees safe in utilization.

Discaling roll adopts the shearing-crushing principle, and principles such as the extruding that non-traditional disintegrating machine adopted, impact.In the shattering process, directly pass through less than the material of product granularity, without fragmentation, and only the material greater than granularity requirements is carried out fragmentation, the material of having avoided the getting into disintegrating machine broken defective of mixing is so have the extremely low degradation rate of crossing.For hard material in coal, the coke etc., degradation rate generally about 5～13%, has greatly improved economic benefit excessively, is fit to very much hard material in coal, the coke etc. is carried out crushing operation.

Adopt the fixed center distance, require adjustment centre-to-centre spacing, realize guaranteeing that rigidity is adjustable under the product granularity prerequisite according to product granularity; Material is carried out broken by force; The physical dimension of discaling roll require to be selected according to product granularity, and the bulk that strict control product passes through is as the final granularity disintegrating apparatus of checking on; Product granularity is evenly qualified, the powder output is few, energy-saving and cost-reducing, service life of equipment is long; Easy to maintenance, scene, crushing teeth wearing and tearing back is butt welding reparation or replacing tooth plate directly, and is convenient and swift, the production maintenance cost is low.

Complete machine is simple to operate, the complete symmetry of two rollers has good interchangeability.Except that being furnished with the protection of current overload protection protection unit and belt transmission; Also be provided with special hydraulic pressure and make a concession protective device and foreign material cleaning plant automatically; Can prevent effectively that nonferromagnetic alloy block, admant piece are to the harm to the discaling roll operate as normal of the destruction of discaling roll and wooden unit and flexible article; Make complete machine reliable, and in case the stall phenomenon appears and just can autostop and send warning, protection machine and whole system.Cancel long gear transmission and yielding system in traditional disintegrating machine, reduced middle energy consumption and trouble point.

Adopt multistage overload protection arrangement, except that Machine guarding, also be furnished with intelligent observing and controlling system, to complete machine operation monitoring in real time, in a single day the stall phenomenon appears in disintegrating machine, and disintegrating machine reports to the police and cuts out feeding system, protection machine and whole system.

The advantage of the utility model is: have classification, broken dual-use function; Simple in structure, easy to maintenance; Operate steadily, protective device is reliable; Product granularity is easy to adjust, and epigranular is qualified; Comprise plurality of specifications, top size can reach 1000mm, and discharging-material size is to 3mm, and disposal ability 10-1000t/h is applicable to the crushing operation of hard material in wet coal, coke, nickel minerals, shale, gangue, slag, lime stone, Gypsum Mine, the petroleum coke etc.

Below in conjunction with accompanying drawing and embodiment the utility model is described further.
