Abstract

The utility model discloses a moving-bar type electromagnetic vibrator. The utility model is characterized in that a vibrating plate is arranged in a filler silo, and is fixedly connected with a moving bar; the moving bar is arranged at the middle of a base and an iron core, and is fixedly connected with an armature; the iron core is wound with coils which is connected with a half-wave device. After the half-wave device being connected with the AC, the discontinuous magnetic force generated by the iron core attracts the armature to drive the moving bar and the vibrating plate to do reciprocating motion. Thereby, the fine materials in the filler silo can not appear the phenomenon of blocking and arch lapping. The utility model has the advantages of simple structure, convenient operation, low energy consumption, low noise, etc.

Description

Moving rod-type electromagnetic vibrator

The utility model relates to a kind of filler bin and dredges materials device, specifically a kind of moving rod-type electromagnetic vibrator.

Present thin materials device mainly contains three kinds: one, the large-scale vibrating hopper by the motor drives curved bar is installed in the filler bin bottom.This apparatus structure complexity, noise is big, big energy-consuming, and inconvenience is safeguarded.Two, in reducing place of filler bin bottom hopper wall vibrator is installed, is impacted bulkhead with dither.This device only limits the use of in the filler bin of thin bulkhead.Three, be installed in side by side on the base plate with two vibrating motors, by base plate or dividing plate vibration bulkhead or powder.This device is installed complicated, and efficient is low, increases the cost of filler bin.More than three kinds of thin materials devices can not reach efficiently, purpose of energy saving.

The purpose of this utility model provides a kind of efficient, and energy-conservation filler bin is dredged the moving rod-type electromagnetic vibrator of material usefulness.

Of the present utility model is to realize like this, support [3] is contained on the bulkhead of filler bin, oscillating plate [1] is located in the filler bin, oscillating plate [1] links to each other with moving bar [2], and moving bar [2] is located at support [3], the centre of iron core [11], and be connected mutually with armature [5], be wound with coil windings [8] on iron core [11], coil windings [8] links to each other with half duration [12], and half duration [12] can be a diode.Be provided with return rubber ring [7] in the outside of iron core [11], the annulus [4] that links to each other with armature [5] contacts with rubber ring [7].

The course of work of the present utility model is such, after half duration [12] is connected 220V, 50HZ AC power, iron core [11] is produced be interrupted magnetic force, magnetic attraction armature [5], after iron core magnetic force disappears, by return rubber ring [7] return, it is reciprocating that armature [5] just drives moving bar [2] like this, thereby make oscillating plate [1] also produce reciprocating motion.Oscillating plate [1] also vibrates the powder in the filler bin thereupon, thereby reaches the effect of dredging material.

The utility model is easy to use, power consumption is little, noise is little, and the filler bin body vibration is little, and is easy to maintenance.The powder of elimination in filler bin can effectively be arranged because of friction, obstruction, tower doming effect that charged and composition deviation etc. causes.

Accompanying drawing one is a structural representation of the present utility model.

Accompanying drawing two is an electromagnetic force fundamental diagram of the present utility model.

Now in conjunction with the accompanying drawings embodiment of the present utility model is further specified:

Support [3] is contained on the bulkhead outside of filler bin, oscillating plate [1] is located in the filler bin, oscillating plate [1] is connected mutually with moving bar [2], moving bar [2] is located at support [3], the centre of iron core [11], and fix with armature [5], on iron core [11], be wound with coil windings [8], be provided with return rubber ring [7] in the outside of iron core [11], the annulus [4] that links to each other with armature [5] contacts with rubber ring [7], and its effect is armature [a 5] return.Between moving bar [2] and support [3], be provided with wear ring [9],, on armature [5], be provided with yielding rubber circle [10] in order to reduce noise.Coil [8] joins with half duration [12], and its effect is to produce to be interrupted magnetic force.Half duration [12] can be a diode.In order to protect moving bar [2], be provided with lid [6] at armature [5] and moving bar [2] place that is connected.
