星型卸料器工作原理：卸料器是由帶有數(shù)個(gè)葉片的轉(zhuǎn)子在圓筒形機(jī)殼內(nèi)旋轉(zhuǎn)，從上部料斗落入的物料，充塞在葉片間的空格內(nèi)，隨葉片的旋轉(zhuǎn)而卸出。星型卸料器工作時(shí)，粉塵靠自身重力落下，充滿上面和側(cè)面的星形葉片空格內(nèi)。葉片轉(zhuǎn)子由電動(dòng)機(jī)通過減速機(jī)轉(zhuǎn)動(dòng)軸帶動(dòng)，葉輪轉(zhuǎn)到下部粉塵靠自重卸下。這種卸塵器一般都安裝在除塵器灰斗下部，為保證連接處的嚴(yán)密不漏風(fēng)，在回轉(zhuǎn)卸料器的上部應(yīng)經(jīng)常保持（儲(chǔ)存）一定高度的粉塵。因?yàn)槿~輪轉(zhuǎn)動(dòng)時(shí)，卸完粉塵后葉輪轉(zhuǎn)上的那一面經(jīng)常是沒有粉塵的，所以容易使空氣漏入。為了保證不漏氣應(yīng)保持一定高度的灰塵柱，使其不致卸空，在灰斗內(nèi)裝設(shè)料位信號(hào)設(shè)施，并與卸塵閥的電動(dòng)機(jī)建立連鎖。

Working principle of star discharger: the discharger is a rotor with several blades rotating in the cylindrical shell. The materials falling from the upper hopper are filled in the space between the blades and discharged with the rotation of the blades. When the star unloader works, the dust falls down by its own gravity and fills the space of the star blade on the top and side. The blade rotor is driven by the motor through the rotating shaft of the reducer, and the impeller rotates to the lower part, and the dust is unloaded by its own weight. This type of dust remover is generally installed at the lower part of the ash hopper of the dust remover. In order to ensure the tightness of the connection and no air leakage, a certain height of dust should be kept (stored) at the upper part of the rotary unloader. When the impeller rotates, the side on which the impeller rotates after the dust is discharged is often free of dust, so it is easy to leak air. In order to ensure that there is no air leakage, a certain height of dust column shall be maintained so that it will not be emptied. Material level signal facilities shall be installed in the ash hopper and interlocked with the motor of the dust discharge valve.

星型卸料器又稱為電動(dòng)卸灰閥、關(guān)風(fēng)器，剛性葉輪給料機(jī)等，是除塵設(shè)備，輸送、排灰、關(guān)風(fēng)和其它設(shè)備給料的主要裝置，適用于各種粉狀物料、顆粒物料的輸送。它由電機(jī)、齒差行星減速器（X）或針綸擺線減速機(jī)（Z）與轉(zhuǎn)龍式卸料器等三大部分組成。一般分為兩大系列，60多種規(guī)格。即A型和B型兩大系列，進(jìn)出口法蘭方形的為A型，圓形的為B型。星型卸料器閥體和葉輪可用鋼板焊制，也可鑄造。采用鑄造方式葉片耐磨性好，葉片與傳動(dòng)軸鋼型連接結(jié)構(gòu)緊湊工作可靠，可以做成鑄鐵、鑄鋼、不銹鋼等材質(zhì)的。

Star type discharger is also known as electric ash discharge valve, air shutoff, rigid impeller feeder, etc. it is the main device for dust removal equipment, conveying, ash discharge, air shutoff and other equipment feeding, and is suitable for conveying various powdery materials and granular materials. It is composed of three parts: motor, tooth difference planetary reducer (x) or needle fiber cycloid reducer (z) and rotary dragon unloader. It is generally divided into two series and more than 60 specifications. I.e. type A and type B series. The square inlet and outlet flanges are type A and the round ones are type B. The valve body and impeller of star unloader can be welded with steel plate or cast. The cast blade has good wear resistance. The blade and the transmission shaft are connected in a compact structure and work reliably. It can be made of cast iron, cast steel, stainless steel and other materials.
