Description
技术领域technical field
本实用新型属于物料分离领域，涉及一种砖混颗粒分离加工系统。The utility model belongs to the field of material separation, and relates to a brick-concrete particle separation and processing system.
背景技术Background technique
随着经济的快速发展，许多建筑需要拆迁重建，产生了数以万计的建筑垃圾。其中经过初步处理粒径分级的砖混建筑垃圾物料虽在社会中有所使用，现有许多科研机构将其运用于道路的路基以及路面的基层建设当中，但表面覆盖大量风化粉末或破碎的细料的砖混建筑垃圾物料工程性质不良，特别是砖混建筑垃圾中的砖颗粒和颗粒表面的大量粉末，吸水率大，遇水软化、膨胀，强度降低，易风化成粉末，其中的大量粉末吸附在颗粒表面形成软弱层，影响颗粒之间的联结，同时也会增加水以及胶凝材料的用量，增加工程造价，影响工程建筑物的强度和稳定性，而且建筑垃圾处理厂家所提供的砖混物料的红砖、混凝土比例变化巨大，材料性质极不均匀，导致工程结构物的均一性、稳定性、整体性极差。故砖混建筑垃圾在社会上少有使用，不利于砖混建筑垃圾的的消耗与充分利用。With the rapid economic development, many buildings need to be demolished and rebuilt, resulting in tens of thousands of construction wastes. Among them, although the brick-concrete construction waste materials that have undergone preliminary treatment and particle size classification are used in the society, many scientific research institutions have used them in the construction of road subgrades and pavement bases, but the surface is covered with a large amount of weathered powder or broken fine particles. Brick-concrete construction waste materials have poor engineering properties, especially the brick particles in the brick-concrete construction waste and a large amount of powder on the surface of the particles. It is adsorbed on the surface of the particles to form a weak layer, which affects the connection between the particles. At the same time, it will increase the amount of water and cementitious materials, increase the cost of the project, and affect the strength and stability of the engineering building. The proportion of red brick and concrete in the mixed material varies greatly, and the material properties are extremely uneven, resulting in extremely poor uniformity, stability and integrity of the engineering structure. Therefore, brick-concrete construction waste is rarely used in society, which is not conducive to the consumption and full utilization of brick-concrete construction waste.
现有的砖混分离产品中，砖混混合料颗粒分离研究较少，大多数筛分设备多将建筑垃圾粉碎筛分后，红砖颗粒、混凝土颗粒混杂在一起，而且一个建筑垃圾处理厂的砖混建筑垃圾砖混比例不一致，造成材料性质不均匀，各种物理、化学参数差距很大，极大地限制了砖混建筑垃圾集料的大规模使用与消耗。Among the existing brick-concrete separation products, there are few studies on the particle separation of brick-concrete mixtures. Most screening equipment crushes and sieves the construction waste, and the red brick particles and concrete particles are mixed together. The proportion of brick-concrete construction waste is inconsistent, resulting in uneven material properties and a large gap in various physical and chemical parameters, which greatly limits the large-scale use and consumption of brick-concrete construction waste aggregates.

本实用新型的具体操作过程为：The concrete operation process of the present utility model is:
砖混颗粒经进料斗1进入到第一传送带2上，再通过烘干设备3进行烘干，然后进入倾斜振动台5中进行振动，通过振动初步分离颗粒与颗粒表面松散的细料及粉末，然后传递到第二传送带7上，第二传送带7将砖混颗粒以一定速度送入箱体13中，同时与鼓风系统9输出的风相遇，其中风带动粉末进入到风导管15中，并将风导管15进入到粉尘处理池16中，剩余的砖混颗粒以一定速度v0向前运动，并在重力的作用下进行分离，同时通过分离挡板进行遮挡，其中，较重的混凝土集料掉落到第一出料口24中，较轻的红砖集料则掉落到第二出料口14中，振动散落的细料则掉落到第三出料口11中。The brick-concrete particles enter the first conveyor belt 2 through the feeding hopper 1, are dried by the drying equipment 3, and then enter the inclined vibration table 5 to vibrate. Then it is transferred to the second conveyor belt 7, and the second conveyor belt 7 sends the brick-concrete particles into the box 13 at a certain speed, and at the same time meets the wind output by the blowing system 9, wherein the wind drives the powder into the air duct 15, and The air duct 15 enters the dust treatment tank 16, and the remaining brick-concrete particles move forward at a certain speed v 0 , and are separated under the action of gravity, and at the same time are shielded by the separation baffle, among which the heavier concrete collects. The materials fall into the first discharge port 24 , the lighter red brick aggregates fall into the second discharge port 14 , and the fine materials scattered by vibration fall into the third discharge port 11 .
本实用新型中风导管15的端部插入于粉尘处理池16中，将粉尘导入粉尘处理池16中，通过水的吸附及沉淀作用将粉尘收集，阻止空气中残留的粉尘进入空气中，减少空气污染，从而实现对砖混集料的除尘和回收，提高砖混颗粒的使用质量；另外，通过格栅网12可以有效防止集料颗粒中的大颗粒以及其他杂物进入鼓风系统9中。The end of the stroke duct 15 of the present invention is inserted into the dust treatment tank 16, the dust is introduced into the dust treatment tank 16, and the dust is collected by the adsorption and precipitation of water, preventing the dust remaining in the air from entering the air, reducing air pollution , so as to realize the dust removal and recovery of the brick-concrete aggregate, and improve the use quality of the brick-concrete particles;
当砖混颗粒以v0的速度水平飞出时，颗粒受到自身重力、风力以及空气摩擦阻力的作用，因为空气的摩擦阻力不大，且对砖颗粒、混凝土颗粒的作用效果一致，这里不计空气的摩擦阻力，并对颗粒进行受力分析，从而了解两者以及粉尘的运动轨迹，如图3所示，对颗粒水平方向进行受力分析：When the brick-concrete particles fly out horizontally at the speed of v 0 , the particles are affected by their own gravity, wind and air frictional resistance, because the frictional resistance of the air is not large, and the effect on the brick particles and concrete particles is the same, and the air is not considered here. The friction resistance of the particles is analyzed, and the force analysis of the particles is carried out to understand the movement trajectory of the two and the dust. As shown in Figure 3, the force analysis of the particles in the horizontal direction is carried out:
f风·cosα＝max (1)f wind ·cosα = max (1)
mg-f风sinα＝may (2)mg-f wind sinα=ma y (2)
由于砖混颗粒大小相近，这里我们假定两者体积相等，受到的风力面积相等，砖混颗粒受到的风力大小相等，同时砖的密度大约为 1.8g/cm3，混凝土的密度约为2.3g/cm3，则砖颗粒的质量要小许多，由公式1和公式2得：Since the size of the brick-concrete particles is similar, here we assume that the volume of the two is equal, the wind force area is equal, and the wind force size of the brick-concrete particles is the same. At the same time, the density of brick is about 1.8g/cm 3 , and the density of concrete is about 2.3g/cm cm 3 , the mass of the brick particles is much smaller, which can be obtained from formula 1 and formula 2:
由公式3知，砖颗粒下落时间要比混凝土颗粒下落的时间长，水平方向的速度要比混凝土颗粒的速度快，因此混凝土颗粒落在近处，砖颗粒将会落在远处，同理，颗粒倾斜向上飞出时也满足，基于该原理，实现砖混颗粒的分离。According to formula 3, the falling time of brick particles is longer than that of concrete particles, and the speed in the horizontal direction is faster than that of concrete particles. Therefore, when concrete particles fall close, brick particles will fall far away. Similarly, It is also satisfied when the particles fly out obliquely upward. Based on this principle, the separation of brick-concrete particles is realized.
所述仅为本实用新型的一种样例，但本实用新型的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本实用新型的保护范围之内。因此，本实用新型的保护范围应以权利要求的保护范围为准。The above is only an example of the present invention, but the protection scope of the present invention is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present invention. , all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
