Abstract

The utility model relates to a circular spring type co-vibration mill, which comprises a circular spring coil, an exciting mechanical spring, and a grinding barrel; a plurality of the exciting mechanical springs are provided between the outer loop of the circular mechanical spring and the inner loop of the circular ring mechanical spring which is the grinding barrel. A vibrating motor is positioned on the lower part of a grinding unit and provided with a bottom support for supporting the co-vibration mill. An isolation spring is provided between the grinding unit and the bottom support. The structure of the circular spring changes the mechanical property of the supporting spring of a prior vibrating mill. The prior support damping spring of the vibration mill becomes an exciting mechanical spring grinding barrel and directly generates oscillation under the shock excitation of the circular spring. The structure strength of the mill can be improved obviously.

Description

Annular spring formula resonance mill

Technical field:

The utility model relates to a kind of vibromill, is specifically related to a kind of resonance mill of annular spring formula structure, belongs to " grinding mill of band vibrator " technical field in the International Classification of Patents B02C19/16 reducing mechanism.

Background technology:

The operation principle of vibromill is to produce dither by vibrator, drives mill tube and abrasive media and carries out high-strength impact and grinding.Medium in mill tube impact and rotatablely move material in the tube formed impact comminution, fatigue rupture and immixture, thereby realize material grinding.The support shock-absorbing spring of existing vibromill because the structural design form is single, has influence on the stress form of mill tube, makes the parameter of aspects such as the structural strength of grinding machine and whole operating mode, noise that the possibility of further improvement all be arranged.

Summary of the invention:

The purpose of this utility model makes at the structural strength that improves grinding machine, simplifies housing construction, reduces the grinding machine noise, improves the reliability of machine, and a kind of annular spring formula resonance mill is provided.

The technical solution of the utility model is as follows.

A kind of annular spring formula resonance mill is made up of lapping device, vibrating device and underframe, and lapping device is made up of annular spring coil (1,2), exciting vibration spring (3) and mill tube (4); Vibrating device is made up of vibrating motor (5) and isolation spring (6), and whole mill body is seated on the underframe (7).Being provided with several exciting vibration springs (3) between annular spring outer ring (1) and the annular spring inner ring (2), is mill tube (4) in the annular spring inner ring (2).Vibrating motor (5) is positioned at the below of lapping device, and is provided with underframe (7) support resonance mill.Between lapping device and underframe (7), be provided with isolation spring (6).

The utility model can also adopt common electric machine to add vibrator and realize, in this design, the quantity of mill tube (mill pipe), the quantity of motor all can change.Can be several forms such as the single tube list drives, the multitube list drives, multitube drives more.In this class design, underframe (7) is positioned at the bottom of whole resonance mill, and motor (8) is flexible coupling with vibrator (9); In the situation of single mill tube, vibrator (9) places the two ends of mill tube; In the situation of a plurality of mill tubes, vibrator (9) places the middle position between several mill tubes.

Described spring can be steel spring, rubber spring, air spring, complex spring etc., and its form can be made up of a plurality of springs, also can be made up of the ring spring of one or more one.

The beneficial effects of the utility model are: annular spring structure has changed the mechanical property of the support spring of existing vibrating mill, changes the exciting vibration spring mill tube into by the support shock-absorbing spring that has vibromill now and directly produce vibration under the vibrational excitation of ring spring.Because the change of mill tube stress form significantly improves the structural strength of grinding machine, housing construction is simplified greatly.Machine reliability improves 2-4 doubly than existing grinding machine.The annular spring can fuse with vibrator, and adopts two-stage vibration isolation to be designed to real resonant grinding machine.Adopt annular spring structure can be easily the basic frequency ratio of grinding machine to be controlled between the 0.7-3.The characteristics of resonance mill be can be less exciting force obtain bigger amplitude.Thus, the energy consumption of grinding machine can reduce 30-50%, and the stressing conditions of bearing also is greatly improved, and the life-span of bearing is improved 30-50%, and the active force that the noise of while grinding machine reaches the basis also all can reduce, thereby makes the variation of the operating mode generation matter of grinding machine integral body.

The specific embodiment:

The utility model can have numerous embodiments.In its first kind of embodiment, vibromill has adopted vibrating motor, just has the motor of vibrator, thereby is designed to motor is placed the lapping device below.And in other each embodiment, adopt common drive motors, and add vibrator, according to different purposes and needs, can change the quantity of the quantity of drive motors and mill tube (mill pipe), can be divided into that the single tube list drives, the multitube list drives, multitube drives more.The single tube list drives and promptly disposes drive motors of a mill tube, as shown in Figure 2; Two the driving of single tube promptly disposed two drive motors of a mill tube, as shown in Figure 3; The multitube list drives and promptly disposes two or more mills Guan Yitai drive motors, and its typical example as shown in Figure 4; More multitube drives and promptly disposes two or more mill pipes two or two above drive motors, and its typical example as shown in Figure 4.

Add vibrator at the employing common electric machine and realize in the design of the present utility model, underframe (7) is positioned at the bottom of whole resonance mill, and motor (8) is flexible coupling with vibrator (9).In the situation of single mill tube as shown in Figure 2, vibrator (9) places the two ends of mill tube.In the situation of a plurality of mill tubes thereafter, vibrator (9) places the middle position between several mill tubes.

In addition, in many mill tubes structure, can also be divided into vertical and horizontal two kinds according to the connected mode of mill tube.For example: what show among Fig. 5 is vertical, and what show among Fig. 6 is horizontal.
