    螺旋輸送機的進料布置:
    Feeding arrangement of screw conveyor:
    螺旋輸送機設計中較為重要的是物料的裝載比例及方法,因為在考慮輸送機的能力及功率時一般要基于所選擇裝載體積的百分數(即填充系數)。各種不同的裝料布置介紹如下:
    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:
    固定裝料:
    Fixed charge:
    由特殊設計的輸送螺旋密封在管狀槽體里組成的螺旋給料機,能使物料在預定速度下從料倉中將物料輸出,輸出的物料量與物料的高度無關。
    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.
    旋轉葉輪給料機是采用圓筒形的上面裝有特定體積的旋轉葉輪,以一定的轉速排出物料。其給料量由轉速來確定??膳c螺旋輸送機一起同步傳動或者用固定速度或變速的傳動裝置單獨傳動。
    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.
    多點裝料:
    Point loading:
    常常要求布置具有多點進料的輸送機,它必須用人工來調節。當在任何給定時間里僅需打開一個進料口時,應限制閘門或開關裝置在較大開度時不允許使輸送機超載。當需要開啟一個以上進料口時,必須小心地調節限制每個進料口的流量,以使其總量不要超過輸送機的設計能力限。當多個進料口需要全部打開同時向輸送機加料時,必須控制總的物料流量。
    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.
    從固定貯倉裝料:
    From the fixed silo loading:
    當直接由固定貯倉裝料的螺旋輸送機,而又沒用流量調節裝置,則大大地增加了超載的危險。為此,可在電機控制器上附加指示負載電流的安培計,這是一種簡單而實用的方法用以指示達到大負載。此方法特別適用于手工操作來控制螺旋輸送機的裝料的場合。
    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.
    緩沖裝料:
    Loading buffer:
    物料常常需要垂直落到輸送機入口的折邊上,由于物料塊或顆粒的慣性會產生沖擊,有碰壞或磨損設備的可能。為此可在進口溜槽中安裝折流擋板或緩沖腔來加以克服。
    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.
    螺旋輸送機的卸料布置:
    Unloading arrangement of screw conveyor:
    標準卸料是廣泛采用的卸料布置之一,采用標準卸料口來約束物料的卸出并直接將物料送入后續的設備或貯存裝置。
    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.
    終端卸料類似標準卸料口。但卸料口位于螺旋輸送機槽體的末端,其端部法蘭與槽體端部連成一體。
    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.
    無接管的卸料口:
    Non discharge port:
    物料經過螺旋槽體底部的一個開口直接落下。一般均用于裝置的中部卸料,在該點卸料直到沒有落料差時都無需停止卸料。例如用于向料庫卸料。
    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.
    開底卸料:
    Bottom discharge:
    用于向料斗、料倉或料庫堆垛中卸料及布料。在輸送機螺旋槽體的底部任意要求的長度開口卸出物料。物料堆積起來形成一自然料堆,后面繼續來的物料通過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.
    螺旋槽體端部卸料:
    Spiral groove end unloading:
    物料直接通過螺旋輸送機槽體端部的開口卸出。螺旋由局部端板支承,軸承安裝在端部的法蘭上。當輸送機填充系數超過0.45時將不能采用這種卸料方法。
    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.
    端部敞開卸料:
    Open end discharge:
    螺旋輸送機尾節螺旋采用標準的懸掛軸承支承,這種形式的卸料布置可自由地將物料卸至料倉或貯料堆及類似的地方。
    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.
