Abstract

The invention provides a method for changing slow discharge of a vibrating screen classifier and belongs to the technical field of equipment maintenance. The method for changing slow discharge of the vibrating screen classifier includes steps of changing an included angle of an upper heavy hammer and a lower heavy hammer and increasing weight of eccentric blocks of the vibrating screen classifier, wherein the smaller the included angle is, the higher the eccentric force is, the shorter the time of materials on a screen is, and the faster discharge is. By changing the included angle of the upper hammer and the lower hammer, motion track and stay time of the materials on the screen can be changed, the smaller the included angle is, the higher eccentric force is, the shorter the time of the materials on the screen is, and the faster the discharge is, so that the method is suitable for roughly screening and screening large-particle materials; the weight of the eccentric blocks is increased, the excitation force of the integral classifier is increased, material proportion is different according to the number of layers of the vibrating screen classifier, and the optimal screening effect of the vibrating screen classifier is achieved by increasing the weight of the eccentric blocks.

Description

Improve the method that vibrating screen classifier discharge is slow

?

Technical field

The invention belongs to plant maintenance technical field, particularly relate to and a kind ofly improve the slow method of vibrating screen classifier discharge.

Background technology

Vibrating screen classifier discharge is slow, or discharge is not the large problem that vast applying unit often runs into, a lot of use producer thinks that this is the problem of machine, do not design when thinking that vibrating screen classifier designs, this problem is the most common in fact is also the problem preferably solved because everything all with vibrating screen classifier vibroseis---vibrating motor has relation.

Vibrating motor is combined by upper and lower two weights (also becoming eccentric fast), two weights its rotor unbalance when work, rotor balancing amount within the scope of permissible value in motor run very normal, after aequum goes beyond the scope, vibrations will be caused, amount of unbalance is larger, shakes larger.

Summary of the invention

For above-mentioned technical problem, the invention provides and a kind ofly improve the slow method of vibrating screen classifier discharge.

For solving the problems of the technologies described above, the present invention improves the slow method of vibrating screen classifier discharge, is realized by following technical proposals:

(1) angle of lower heavy punch in change, the eccentric force of the less generation of angle is larger, and the time that material stops on screen cloth is shorter, and discharging is just fast;

(2) weight of vibrating screen classifier eccentric block is increased.

The present invention improves the slow method of vibrating screen classifier discharge, the angle of lower heavy punch in change, just can change the movement locus of material on screen cloth and the time of staying, the larger eccentric force that it produces of angle is less, the time that material stops on screen cloth is longer, that sieves is meticulousr, discharging is also just slow accordingly, otherwise the eccentric force of the less generation of angle is larger, the time that material stops on screen cloth is shorter, discharging is also just very fast, and this situation is relatively applicable to scalping and the oarse-grained material of sieve; Increase the weight of eccentric block, the exciting force of complete machine will be increased, according to the number of plies of user's vibrating screen classifier, the difference of material proportion, the screening effect that the eccentric fast weight of suitable increase can make screening machine reach best.

Detailed description of the invention

Below by specific embodiment, the present invention is further illustrated.

Vibrating motor is combined by upper and lower two weights (also becoming eccentric fast), two weights its rotor unbalance when work, rotor balancing amount within the scope of permissible value in motor run very normal, after aequum goes beyond the scope, vibrations will be caused, amount of unbalance is larger, shakes larger.

So be aware of its operation principle, the problem that all right solution discharge capacity is slow, that regulates upper and lower two weights exactly.

The angle of lower heavy punch in change, just can change the movement locus of material on screen cloth and the time of staying, the larger eccentric force that it produces of angle is less, the time that material stops on screen cloth is longer, screening meticulousr, and discharging is also just slow accordingly, otherwise the eccentric force of the less generation of angle is larger, the time that material stops on screen cloth is shorter, and discharging is also just very fast, and this situation is relatively applicable to scalping and the oarse-grained material of sieve.So client according to the difference of the material properties of self, should regulate the angle between two eccentric blocks, make the distribution of material, treating capacity, separative efficiency, cross the various changes such as net rate, be adjusted to optimum state.

Have is exactly increase eccentric fast weight again.If increase the weight of eccentric block, the exciting force of complete machine will be increased, according to the number of plies of user's vibrating screen classifier, the difference of material proportion, the screening effect that the eccentric fast weight of suitable increase can make screening machine reach best.

It is all the same that vibrating screen classifier sets when dispatching from the factory, and the material of screening has 1,100 kinds, and the way of adjustment also has 1,100 kinds, finds the angle of oneself material screening the suitableeest, and screening efficiency just can be made to reach maximum.

Claims (1)

1. improve the method that vibrating screen classifier discharge is slow, it is characterized in that comprising the following steps:

(1) angle of lower heavy punch in change, the eccentric force of the less generation of angle is larger, and the time that material stops on screen cloth is shorter, and discharging is just fast;

(2) weight of vibrating screen classifier eccentric block is increased.
