一、正确选用电磁除铁器须同时考虑物料的含铁情况.除铁要求、使用环境和除铁器自身的特性 当物料用胶带输送机运送时,要把胶带机的因素考虑在内。
First, the correct selection of electromagnetic iron remover must consider the iron content of the material at the same time. In addition to the requirements of iron, the environment of use and the characteristics of the iron remover, the factors of belt conveyor should be taken into consideration when the material is transported by belt conveyor.
二、当物料中含铁较多时,应选用连续排铁能力的自卸式电磁除铁器,选用自卸式电磁除铁器可有效保护胶带输送机免遭纵向撕裂之虞。
Two, when the iron content is relatively large, the self discharging electromagnetic iron remover with continuous iron removal capacity should be selected. The self unloading electromagnetic iron remover can effectively protect the belt conveyor from longitudinal tear.
三、当物料中含铁较少时。宜选用人工除铁式电磁除铁器。可适当降低悬挂高度,有利于出铁。但采用人工除铁的除铁器,当铁杆一头吸起并被紧紧吸住时,另一头如顶住输送胶带则容易发生胶带纵向撕裂事故。
Three. When there is less iron in the material. It is advisable to choose an iron removal iron remover with artificial iron removal. It can properly reduce the height of the suspension, which is beneficial to the iron production. But the artificial Deferrizater iron, when the iron head sucked up and is firmly suck, another head as against the conveyor belt is prone to accident belt longitudinal tearing.
四、当使用环境粉尘(如煤尘、烟尘、泥尘、灰尘等)较严重时。应选用全封闭结构的除铁器。
Four, when the use of environmental dust (such as coal dust, dust, dust, dust, etc.) is more serious. Iron remover with fully enclosed structure should be selected.
五、电磁除铁器安装在中部(即同线布置)时,因物料有前冲力和处于松散状有利于除铁。悬挂高度可适当增加。但除铁器磁极法线方向800mm内的铁质构件应改为非磁性材料。
Five. When the electromagnetic iron remover is installed in the middle (that is, the same line arrangement), the material has the front force and the loose shape is beneficial to the iron removal. The suspension height can be increased properly. However, the iron components in the direction of 800mm in the direction of the magnetic pole of the irons should be changed to nonmagnetic materials.
六、电磁除铁器安装在中部(即交叉布置)时,为提高除铁效果,可在胶带下增装一非磁性直线托辊。
Six. When the electromagnetic iron remover is installed in the middle (that is, cross layout), in order to improve the effect of iron removal, a nonmagnetic straight line roller can be installed under the tape.
七、当胶带运输机的带速大于2.5m S时,通常除铁器应装在头部。如采用提高磁场强度的办法,并配以非磁性托辊,亦可装于中部,同样可取得良好的除铁效果。
Seven. When the belt speed of the conveyor is greater than 2.5m S, the iron remover is usually installed in the head. If the method of improving the magnetic field strength is adopted, and the non magnetic roller is used, it can also be installed in the middle, and the good effect of iron removal can be obtained.
八、一般情况下,除铁器的磁系结构为开式磁路,其吸铁有下列特点;吸大的长的易于小的短的;吸尖的易于球的;吸动的易于静的。因此,对除铁要求较高的场合,应适当提高除铁器的规格或采用两级、三级除铁。
Eight, under normal circumstances, the magnetic structure of the iron separator is open magnetic circuit, and its iron absorption has the following characteristics: large and long, easy to short, easy to absorb and easy to move. Therefore, in the case of high requirement for iron removal, the specification of the iron remover or the use of the two and three levels of iron removal should be properly improved.
九、采用多级除铁器时.后级的除铁能力应高于前级的除铁能力,即后级除铁器在胶带表面的磁场力(CH)应大于前级胶带表面的磁场力(CH2)。.否则,后级除铁器除铁效果很差。
Nine, when using multistage iron remover, the iron removal ability of the later stage should be higher than that of the prior stage, that is, the magnetic force (CH) of the later stage iron remover on the surface of the adhesive tape should be larger than the magnetic force on the surface of the front belt (CH2). Otherwise, the effect of iron removal in the post stage is very poor.
十、当物料含铁少时,采用金属探测器配合电磁除铁器(选用短时工作制)联合使用,可获得更好效果。
Ten. When the material is less iron, the combined use of metal detector and electromagnetic iron remover (short time working system) can get better results.
