Abstract
The utility model discloses a ball mill comprising a cylinder body used for holding materials and a grinding body arranged in the cylinder body for crushing the materials, wherein a lining plate is fixed on the inner wall of the cylinder body, and a noise absorption layer is arranged between the lining plate and the inner wall of the cylinder body. According to the utility model, the noise absorption layer used for absorbing impact force is arranged in the cylinder body to relieve the vibration of the cylinder body and absorb the noise in the cylinder body so as to achieve a noise reduction target. A vacuum cover is used for forming a vacuum layer to further prevent the noise transmission and reduce the noise. A reinforcement rib can be used for improving the strength of the vacuum cover and facilitating the installation of other equipment. An arranged fixing hole can be used for avoiding the mutual effect of a fixing bolt of the cylinder body and the vacuum cover so as to improve the working efficiency in maintenance and installation processes. The ball mill disclosed by the utility model is simple in structure and is capable of reducing the original 110 decibel noise to about 30 decibel, thereby greatly reducing injury of onsite noise on a human body.
Description
Technical field
The utility model relates to mechanical field, is specifically related to a kind of ball mill that can reduce noise and realize pipelining.
Background technology
Ball mill is after material is broken, the key equipment of pulverizing again.It is widely used in cement, silicate product, production industries such as New Building Materials, refractory material, chemical fertilizer, non-ferrous metal ore and glass ceramics.Existing ball mill generally is divided into tube mill, bar type ball mill, cement ball mill, horizontal ball mill etc., horizontal ball mill comprises the cylindrical shell that has material inlet and outlet of a level, in cylindrical shell, be placed with abrasive body, this cylindrical shell and abrasive body are made by iron and steel, when work between abrasive body and the cylindrical shell violent collision takes place, to pulverize the material in the cylindrical shell, in this process, can produce the noise more than 110 decibels, this causes very big influence to environment and staff.
The utility model content
For solving the big problem of ball mill operating noise in the prior art, the utility model provides a kind of ball mill that can reduce noise.Concrete scheme is as follows: a kind of ball mill, comprise the cylindrical shell that holds material and be arranged on the abrasive body of in the cylindrical shell material being pulverized, it is characterized in that, be fixed with liner plate on the inwall of described cylindrical shell, be provided with the noise absorption layer between described liner plate and the cylinder inboard wall.
For improving damping effect simultaneously and reducing noise: described noise absorption layer is made of flexibility material with holes.
For further reducing noise: the lateral surface of described cylindrical shell is provided with the hollow interlayer that is made of blimp, and described hollow interlayer is a vacuum layer.
For reducing airborne noise: the vacuum of described vacuum layer is 10
-1～10
-3Pa.
For improving the intensity of vacuum (-tight) housing: be provided with in the described vacuum layer along the reinforcement of cylindrical shell arranged radially, described reinforcement adopts the interrupted structure that can supply air to pass.
For making things convenient for installation and maintenance: leave the fixing hole that the bolt for fixed cylinder and liner plate passes on the described blimp, blimp does not contact with bolt.
The utility model is by being provided with the noise absorption layer that absorbs impact in cylindrical shell, can alleviate the vibrations that cylindrical shell is subjected to and receive a noise in the tube when inhaling, and reaches the purpose of noise reduction.Utilizing vacuum (-tight) housing to be divided into vacuum layer can further stop the propagation of noise and reduce noise.Can improve the intensity of vacuum (-tight) housing by reinforcement, the convenient miscellaneous equipment of installing.The fixing hole that is provided with can be avoided influencing each other between cylindrical shell set bolt and the vacuum (-tight) housing, increases work efficiency when safeguarding and install.The utility model is simple in structure, former 110 decibels noise can be reduced to about 30 decibels, greatly reduces the infringement of on-site noise to human body.

The schematic surface of Fig. 2 cylindrical shell;
Label declaration in the accompanying drawing: 1-cylindrical shell, 2-liner plate, 3-noise absorption layer, 4-vacuum (-tight) housing, 401-vacuum layer, 402-reinforcement, 403-fixing hole.
The specific embodiment
As shown in Figure 1, ball mill of the present utility model comprises the cylindrical shell 1 that holds material and is arranged on the abrasive body of in the cylindrical shell 1 material being pulverized, and is fixed with liner plate 2 on the inwall of cylindrical shell 1, is provided with noise absorption layer 3 between liner plate 2 and the cylinder inboard wall.The sound that abrasive body impacts on liner plate 2 when work is absorbed by noise absorption layer 3, can reduce corresponding noise level, noise absorption layer 3 is made of flexibility material with holes simultaneously, flexible structure can alleviate the vibrations that cylindrical shell is subjected to, improve the life-span of each parts on the cylindrical shell, inner hole portion also can stop the propagation of noise in damping, concrete material flexible with holes can adopt rubber, plastic or other material, to reach the purpose of damping in sound absorption.
For further alleviating noise, the utility model is provided with the hollow interlayer that is made of blimp 4 at the lateral surface of cylindrical shell 1, and hollow interlayer is a vacuum layer 401.Vacuum layer 401 can further absorb the noise in the cylindrical shell 1.Wherein the vacuum of vacuum layer 401 is 10
-1～10
-3Pa.For strengthening the intensity of blimp 4, in vacuum layer 401, be provided with along the reinforcement 402 of cylindrical shell 1 arranged radially, reinforcement 402 adopts the interrupted structure that can supply air to pass.Reinforcement not only can support blimp but also do not hinder flowing of internal gas like this.Safeguard cylindrical shell for convenience, leave the fixing hole 403 that the bolt 5 for fixed cylinder 1 and liner plate 2 passes on blimp 4, blimp 4 does not contact with bolt 5.So not only can safeguard blimp separately but also can safeguard cylindrical shell separately, increase work efficiency.
The above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, anyly be familiar with the technical staff of this patent in not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned prompting is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of the utility model scheme.
