Abstract

The utility model relates to a rotary and vibrating type super fine crusher, which is mainly used for a test or a laboratory. The rotary and vibrating type super fine crusher is mainly composed of a machine case, damping layers, a machine base, an electric motor, a spring, a supporting base, a lower vibrating block, an upper vibrating block, a material crushing bowl, a clamping device, an electric motor fixing ring and an eccentric block, wherein, the inner wall of the machine case is provided with a damping layer, a sound-isolating layer and a sound-absorbing layer, and the upper part of the machine base is provided with a damping layer. The utility model organically applies the damping, sound-absorption, sound-isolation, vibration-damping, and other technologies; the machine case is made to form a wide-band sound-isolating body, and the noise of the rotary and vibrating type super fine crusher is reduced from the range of from 20Hz to 20KHz to lower than 70dB. The rotary and vibrating type super fine crusher has the advantages of small size, convenient operation and carrying, low cost, etc.

Description

Low-noise pulverizer
The utility model relates to a kind of disintegrating apparatus, the ultra-fine pulverizer for laboratory test of especially a kind of rotating vibrating type.
At present, ultra-fine assay class pulverizer mainly adopts the impact comminution technology of shaking of revolving, in 5 minutes, mineral powders such as quartz can be broken to 300 orders, and it is simple in structure, need not fixedly mount, but operating noise is big, does not meet national corporate environment noise sanitary standard, especially such pulverizer mainly uses in laboratory or laboratory, and noise problem is one and presses for improved problem.Adopting acoustic hood to reduce noise has certain effect, and little to the service behaviour influence of machine itself, but it can increase the volume and weight of machine significantly, is not easy to carrying and installation, hinders operation, and manufacturing cost is also than higher.
The purpose of this utility model is to overcome the defective that above-mentioned disintegrating apparatus exists, and provides a kind of noise low, and volume is little, and is in light weight, operation convenient in carrying, the low noise pulverizer of low cost of manufacture.
Task of the present utility model is finished in the following manner: this pulverizer mainly by casing, damping layer, support, motor, spring, bearing, down vibrating mass, go up vibrating mass, pulverize material alms bowl, hold down gag, motor retainer ring and eccentric block and form, it is characterized in that on the inwall of casing, being provided with damping layer, puigging and sound absorbing layer are provided with damping layer above bearing.
In order to reduce noise and to reduce and impact, be provided with the vibration isolation rubber circle between spring and the bearing.
In order to reduce vibration and to increase support rigidity, in the support endoporus, be welded with reinforcing ring.
In the utility model, damping layer can adopt pitch or rubber etc., and sound absorbing layer can adopt mineral wool etc., and puigging can adopt sheet metal etc.
The utility model adopts the principle of acoustic hood, utilize the original casing of pulverizer itself, organically use technology such as damping, sound absorption, sound insulation and weakening, make casing form a broadband acoustic isolater, simultaneously between spring, bearing and support drive disk assembly, set up the damping sound insulation material, and increase the rigidity of parts of easily shaking, thereby the noise of pulverizer can be reduced to below the 70dB in the scope of 20HZ~20KHZ.Damping sound insulation layer of the present utility model passes through bonding or screw connecting mode direct and casing is fitted, and sound absorbing layer adopts isolating construction, utilizes Z type circlip to connect with casing, has improved acoustic isolater and has made installation technology.In addition, the utility model also have volume little, in light weight, the operation convenient in carrying, low cost and other advantages.
Concrete structure of the present utility model is provided by drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with drawings and Examples the utility model is described in more detail.
Embodiment:
With reference to Fig. 1, casing 1 is made by sheet metal, on casing 1, be stained with damping layer 2, the sound absorbing layer of being made by super glass wool 4 links by Z-shaped circlip and casing 1, between damping layer 2 and sound absorbing layer 4, be provided with puigging 3, the centre of casing 1 is provided with support 5, the top of support 5 is provided with damping layer 2, bearing 9 and spring 8 are equipped with in the top of support 5, between bearing 9 and the spring 8 vibration isolation rubber circle 16 is housed, be welded with reinforcing ring 6 in the endoporus of support 5, motor retainer ring 14 is housed in the reinforcing ring 6, motor 7 and eccentric block 15, vibrating body 10 is equipped with down in motor retainer ring 14 tops, last vibrating body 11, pulverize material alms bowl 12 and hold down gag 13.

Claims (3)
