双重除尘的粉碎生产线Double dust removal crushing production line

技术领域technical field

本实用新型涉及一种双重除尘的粉碎生产线，属于粉碎机械领域。The utility model relates to a crushing production line with double dust removal, which belongs to the field of crushing machinery.

背景技术Background technique

目前国内用于粉碎的设备一般都为单台粉碎设备，即通常都是用粉碎机将物料粉碎一段时间后再用一定目数的筛进行筛分，不符合粒度要求的物料继续投入到粉碎机中粉碎，如此往复，直到所有的物料都粉碎完并符合要求。这种粉碎方式固然能够将物料粉碎到一定的粒度使其变成合格的产品，但是生产效率太低，不符合规模化生产；另一方面，粉碎机粉碎过程中会产生大量的粉尘，在没有吸尘装置的情况下，对环境会造成很大的粉尘污染。At present, the equipment used for crushing in China is generally a single crushing equipment, that is, the material is usually crushed by a pulverizer for a period of time and then sieved by a sieve with a certain number of meshes. Materials that do not meet the particle size requirements continue to be put into the pulverizer. Crushing in the middle, and so on, until all the materials are crushed and meet the requirements. Although this crushing method can crush the material to a certain particle size to make it into a qualified product, the production efficiency is too low to meet the scale production; on the other hand, a large amount of dust will be generated during the crushing process of the crusher. In the case of a dust collection device, it will cause a lot of dust pollution to the environment.

在现有技术中，也有通过除尘器来除去粉碎过程中的细小尘粒，但是，一个除尘器的除尘效果往往不佳，在除尘器的出口处还是会产生大量的粉尘，造成对空气的污染。In the prior art, there is also a dust collector to remove the fine dust particles in the crushing process, but the dust removal effect of a dust collector is often not good, and a large amount of dust will still be generated at the outlet of the dust collector, causing air pollution .

另外，由于粉碎机在高速旋转的时候，会产生大量的热量，如果热量没有及时被转移，很容易造成粉碎机的损坏或粉碎的物料的变性，而现有技术的冷却方式通常是在粉碎机的轴承中通入冷却水，但由于粉碎机的转动件和静止件之间容易产生缝隙，因此这种方式容易造成冷却水的泄漏，进一步的对粉碎物料产生影响。In addition, when the pulverizer rotates at high speed, it will generate a lot of heat. If the heat is not transferred in time, it is easy to cause damage to the pulverizer or denaturation of the pulverized material. The cooling method of the prior art is usually in the pulverizer. Cooling water is passed into the bearing of the pulverizer, but because there is a gap between the rotating part and the stationary part of the pulverizer, this method is likely to cause leakage of cooling water, which will further affect the pulverized material.
