Abstract
The utility model provides a frequency-adjustable electromagnetic vibrating screen which comprises a frame. A group of swing arms inside the frame are connected to a screen plate frame, and a screen plate is mounted in the screen plate frame. The frequency-adjustable electromagnetic vibrating screen is characterized in that an electromagnetic vibration exciter is arranged between the screen plate and the frame and comprises a static armature connected with the frame and a movable armature connected with the screen plate frame, the static armature is wound with a coil, the coil is connected with a power supply through a circuit breaker which is connected with the movable armature, a reset spring connected with the frame is mounted on one side, opposite to the movable armature, of the screen plate, and the static armature is adjustably connected to the frame. As frequency of the vibrating screen is adjustable, the vibrating screen is capable of meeting requirements of different materials and has wide application range.
Description
Technical field:
The utility model relates to a kind of FM electromagnetic vibratory sieve, belongs to screening plant technical field.
Background technology:
Hummer screen is a kind of conventional screening plant.Hummer screen is generally comprised of parts such as support, vibratory chamber, electromagnetic exciters, after machine vibrator starts, produces the power of shaking, and drives vibratory chamber's vibration, makes the downward layered filtration of material (sieve), reaches the quality requirement of product regulation.The features such as operating efficiency is high, energy consumption is low, noise is little, working stability is reliable because having, part is not fragile for hummer screen, service life are widely used.
Hummer screen generally uses as high frequency shale shaker, but in actual production the vibration of material particles should with the vibration frequency good teamwork of vibratory sieve, and this point just depends on vibratory sieve frequency size, only have the optimum state of being debugged, just can reach best screening effect.The vibration frequency of existing hummer screen is all nonadjustable, causes its scope of application little.
Summary of the invention:
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of FM electromagnetic vibratory sieve, and the frequency of reciprocating sieve can regulate, and adapts to the needs of different material, applied widely.
Above-mentioned object realizes by following technical scheme:
FM electromagnetic vibratory sieve, comprise frame, described frame the inside connects sieve plate framework by one group of swing arm, described sieve plate framework the inside mounted sieve, between described sieve plate framework and described frame, be provided with electromagnetic exciter, described electromagnetic exciter comprises the moving armature that the static gag bit that is connected with described frame is connected with sieve plate framework with described, described static gag bit outside winding around, the circuit on-off device that described coil is connected by the moving armature with described connects power supply, a side relative with described moving armature on described sieve plate is provided with the back-moving spring being connected with described frame, between described static gag bit and described frame, adopt adjustable connection.
Described FM electromagnetic vibratory sieve, described adjustable connection comprises the adjustment screw rod being connected with static gag bit, described adjustment screw rod is connected with adjusting nut through described frame.
Described FM electromagnetic vibratory sieve, described circuit on-off device comprises the armature contact that the fixed contact that is connected with described frame is connected with sieve plate framework with described.
Described FM electromagnetic vibratory sieve, described sieve plate bottom is provided with one group of reinforcement, and described reinforcement is arranged on described sieve plate framework.
Beneficial effect:
1. hummer screen of the present utility model can be adjusted the size of static gag bit to the attraction of moving armature by the distance of adjusting between static gag bit and moving armature, owing to decaying gradually in magnetic field in air, therefore the distance between static gag bit and moving armature is less, so after the coil electricity of static gag bit outside, the magnetic force that static gag bit produces is just larger to the attraction of moving armature, thereby moving armature can obtain a larger acceleration to obtaining a larger power, to static gag bit direction, move fast, in the process of motion, drive armature contact motion and fixed contact to disconnect, the coil losing electricity of static gag bit outside loses magnetism static gag bit, under the pulling force effect of back-moving spring, moving armature is moved back again, otherwise the distance between moving armature and static gag bit is far away, coil electricity makes static gag bit band magnetic afterwards less to the attraction of moving armature, moving armature drives sieve plate less to the speed of static gag bit direction motion, the frequency of vibrations will diminish, can regulate according to actual needs the vibration frequency of vibratory sieve like this, make the applied widely of vibratory sieve.
2. the utility model adopts the mode of adjusting screw rod and adjusting nut to regulate, and regulates convenient.
