Description
Affiliated technical field:
The utility model relates to the Separation of Solid and Liquid process device of fine grained cleaned coal in a kind of coal preparation process, and particularly electromagnetic high-frequency vibratory sieve sieve nest angle hangs adjusting device.
Background technology:
At present, the electromagnetic high-frequency vibratory sieve is widely used in coal preparation plant's coal slime and reclaims, and generally is made up of frame, sieve nest, electromagnetic exciter, gyroaxis, and electromagnetic exciter is arranged on the sieve nest, and an end of sieve nest is hinged by gyroaxis and frame, and sieve nest tilts to place.When the compass screen surface material travels forward speed when too small or excessive, can cause on the compass screen surface material bed blocked up or thin excessively, only the change excitation intensity of electromagnetic exciter of people is deacclimatized material bed variation, but adjustable range is little, and influences the service life of device efficiency and electromagnetic exciter, screen cloth.Someone attempts at an end (feed end) of sieve nest the angular adjustment bar to be set, adjust the angle of inclination of sieve nest, but the height of sieve nest feed end is limited by dispenser or the preceding paragraph sieve nest, and the height that the angular adjustment bar can lifting is limited, the scope that reconcile at the sieve nest angle of inclination is also very little, generally, can not satisfy the production needs far away, and be difficult to online adjustment sieve nest angle of inclination at ± 5 °, make that production is discontinuous, very inconvenient.Common high-frequency electromagnetic vibratory sieve is because the angle of screen(ing) machine and level ground can not online random adjustment, along with the coal separation production process is carried out continuously, the pan feeding concentration of high-frequency electromagnetic vibratory sieve, the granularity of fine grained cleaned coal, the material thickness on the compass screen surface and the movement velocity on compass screen surface constantly changes and cause the Separation of Solid and Liquid process of fine grained cleaned coal not carry out continuously.Sometimes need artificial tool using to take off material on the sieve, increased labour intensity, simultaneously also be easy to damage the screen cloth of high-frequency electromagnetic vibratory sieve; The product moisture of fine grained cleaned coal can not be guaranteed.
The utility model content:
The utility model purpose provides a kind of electromagnetic high-frequency vibratory sieve sieve nest angle and hangs adjusting device; realize not shutting down online adjustment sieve nest angle of inclination; can carry out angle adjustment on a large scale; guarantee to produce continuously; raise the efficiency; control product moisture easily, solve the problems referred to above that background technology exists.
The technical solution of the utility model is: electromagnetic high-frequency vibratory sieve sieve nest angle hangs adjusting device and is made up of electromagnetic high-frequency vibratory sieve frame, sieve nest, screen cloth, gyroaxis, suspension holdfast and suspension actuator, screen cloth is arranged on the sieve nest, sieve nest is hinged by gyroaxis and electromagnetic high-frequency vibratory sieve frame, sieve nest tilts to place, suspension holdfast is fixed on the electromagnetic high-frequency vibratory sieve frame, hang actuator and be arranged on the suspension holdfast, be positioned at the top of sieve nest, hang actuator and be connected with sieve nest.
Hanging actuator can be known wire rope roll actuation mechanism, comprises cylinder, steel wire rope etc., and steel wire rope one end is connected with sieve nest, and the other end is wound on the cylinder.The external force head roll rotates, and is wound on the steel wire rope pull-up on the cylinder or puts down the sieve nest that is attached thereto, the angle of inclination between on-line automatic as required adjustment sieve nest and the ground.The rotation of cylinder can be by motor-driven, also can be manual.
Hanging actuator can also be known hydraulic drive mechanism or electronic push-pull rod body, is implemented in sieve nest overhung push-and-pull sieve nest function, finishes the adjusting to the sieve nest angle of inclination.Hydraulic drive mechanism comprises hydraulic cylinder, magnetic valve etc., and electronic push-pull rod body comprises motor, reductor etc.
Can control automatically by known microcomputer program, each angle of adjusting can change arbitrarily, thereby has reached the tracking adjustment of the Separation of Solid and Liquid process of fine grained cleaned coal, and fine grained head coal product quality and stability thereof are improved; Because the coal preparation plant of certain scale often has several cover high-frequency electromagnetic vibratory sieves, adopts many high-frequency electromagnetic vibratory sieves to concentrate programme-control can also save human resources such as operative employee in a large number.
Adopt the utility model, when the compass screen surface material travels forward speed when too small, cause on the compass screen surface material bed blocked uply, this moment, actuator work was hung in control, put down sieve nest, strengthened the inclination angle between sieve nest and the ground, was convenient to material and travelled forward; When the compass screen surface material travels forward speed when excessive, cause on the compass screen surface material bed thinly excessively, this moment, actuator work was hung in control, and the pull-up sieve nest reduces the inclination angle between sieve nest and the ground, is convenient to rise on the screen cloth upper berth suitable bed (material bed).By adjusting the inclination angle on sieve nest and ground, moisture that can control break oversize material product, when the inclination angle was big, the moisture of product was also bigger, inclination angle hour, the moisture of product is less.With the inclination angle that hangs between actuator adjustment sieve nest and the ground, can intermittently carry out, also can carry out continuously, do not need to shut down, can onlinely finish.Can regulate the inclination angle between sieve nest and the ground on a large scale, generally between 20-40 °, satisfy fully and produce needs.
The utlity model has rational in infrastructure, can not shut down the online characteristics such as sieve nest angle adjustment, angle adjustment scope be big finished, and can conveniently control product moisture.Install angle additional at common high-frequency electromagnetic vibratory sieve and hang adjusting device, can make the serialization of Separation of Solid and Liquid process and the automation of high-frequency electromagnetic vibratory sieve fine grained cleaned coal.
