螺旋输送机的进料布置和卸料布置

螺旋输送机的进料布置:
Feeding arrangement of screw conveyor:
螺旋输送机设计中最为重要的是物料的装载比例及方法,因为在考虑输送机的能力及功率时一般要基于所选择装载体积的百分数(即填充系数)。各种不同的装料布置介绍如下:
The most important thing in the design of the screw conveyor is the loading ratio and the method of the material, because when considering the capacity and power of the conveyor, it should be based on the percentage of the selected loading volume. A variety of different loading arrangement as follows:
固定装料:
Fixed charge:
由特殊设计的输送螺旋密封在管状槽体里组成的螺旋给料机,能使物料在预定速度下从料仓中将物料输出,输出的物料量与物料的高度无关。
The transportation of specially designed spiral sealing screw feeder in the tubular body, can make the material at a predetermined speed from the silo in material output, material quantity and material of the output is independent of the height.
旋转叶轮给料机是采用圆筒形的上面装有特定体积的旋转叶轮,以一定的转速排出物料。其给料量由转速来确定。可与螺旋输送机一起同步传动或者用固定速度或变速的传动装置单独传动。
The rotating impeller feeder is above the cylindrical rotating impeller with a specific volume of the discharge of materials to a certain speed. The feed quantity is determined by the rotational speed. The utility model can be synchronously driven with a screw conveyor or can be independently driven by a fixed speed or variable speed transmission device.
多点装料:
Point loading:
常常要求布置具有多点进料的输送机,它必须用人工来调节。当在任何给定时间里仅需打开一个进料口时,应限制闸门或开关装置在最大开度时不允许使输送机超载。当需要开启一个以上进料口时,必须小心地调节限制每个进料口的流量,以使其总量不要超过输送机的设计能力限。当多个进料口需要全部打开同时向输送机加料时,必须控制总的物料流量。
It is often necessary to arrange a conveyor with multiple points of feed, which must be manually adjusted. When only one opening is opened at any given time, it is necessary to restrict the gate or switch to allow the conveyor to be overloaded at maximum opening. When more than one feed opening is required, the flow rate of each feed inlet must be carefully adjusted so as not to exceed the total capacity of the conveyor. When a plurality of feed ports need to be fully opened and fed to the conveyor, the total material flow must be controlled.
从固定贮仓装料:
From the fixed silo loading:
当直接由固定贮仓装料的螺旋输送机,而又没用流量调节装置,则大大地增加了超载的危险。为此,可在电机控制器上附加指示负载电流的安培计,这是一种简单而实用的方法用以指示达到最大负载。此方法特别适用于手工操作来控制螺旋输送机的装料的场合。
When directly by screw conveyor fixed storage charge, and no flow control device, it has greatly increased the risk of overload. Therefore, additional instructions load current ammeter in the motor controller, which is a simple and practical method for indicating the maximum load. This method is suitable to control the screw conveyor in manual loading.
缓冲装料:
Loading buffer:
物料常常需要垂直落到输送机入口的折边上,由于物料块或颗粒的惯性会产生冲击,有碰坏或磨损设备的可能。为此可在进口溜槽中安装折流挡板或缓冲腔来加以克服。
Materials often need to vertically fall into the entrance of the folding conveyor, because the material block or particle inertia impact, have broken or worn equipment may. This could be the baffle or buffer chamber mounted on the inlet chute to overcome.
螺旋输送机的卸料布置:
Unloading arrangement of screw conveyor:
标准卸料是最广泛采用的卸料布置之一,采用标准卸料口来约束物料的卸出并直接将物料送入后续的设备或贮存装置。
Standard discharge is one of the most widely used unloading arrangement, which is to use the standard discharge port to restrict the discharge of material and to directly feed the material into the following equipment or storage device.
终端卸料类似标准卸料口。但卸料口位于螺旋输送机槽体的最末端,其端部法兰与槽体端部连成一体。
Terminal discharge similar to standard discharge port. But the end of the discharge port is located in the groove of the screw conveyor, the end part of the flange and the groove end together.
无接管的卸料口:
Non discharge port:
物料经过螺旋槽体底部的一个开口直接落下。一般均用于装置的中部卸料,在该点卸料直到没有落料差时都无需停止卸料。例如用于向料库卸料。
The material through an opening at the bottom of the spiral groove directly fall. Generally used in the middle of the discharge device, at the point of unloading until there is no material difference between the need to stop unloading. For example, for material unloading.
开底卸料:
Bottom discharge:
用于向料斗、料仓或料库堆垛中卸料及布料。在输送机螺旋槽体的底部任意要求的长度开口卸出物料。物料堆积起来形成一自然料堆,后面继续来的物料通过料堆送到未卸科的地方。
To the hopper, the hopper or silo unloading and stacking of cloth. At the bottom of any required length of conveyor spiral groove opening unloading material. The material is piled up to form a natural material pile, and the material coming from the back is sent to the unloaded place through the material heap.
螺旋槽体端部卸料:
Spiral groove end unloading:
物料直接通过螺旋输送机槽体端部的开口卸出。螺旋由局部端板支承,轴承安装在端部的法兰上。当输送机填充系数超过0.45时将不能采用这种卸料方法。
The material directly through the opening at the end part of the screw conveyor unloading tank. The screw is supported by a local end plate and the bearing is mounted on the flange of the end. This unloading method cannot be used when the fill factor of the conveyor is over 0.45.
端部敞开卸料:
Open end discharge:
螺旋输送机尾节螺旋采用标准的悬挂轴承支承,这种形式的卸料布置可自由地将物料卸至料仓或贮料堆及类似的地方。
Suspension bearing screw conveyor tail section spiral with a standard, this form of unloading arrangement may be free to material unloading to the silo or storage piles and similar places.
