弛张筛厂家

弛张筛(shai)(shai)(shai)(shai)是我(wo)厂(chang)生产的(de)一种新型筛(shai)(shai)(shai)(shai)分(fen)机(ji)械(xie)，可筛(shai)(shai)(shai)(shai)分(fen)建(jian)筑装修(xiu)垃(la)圾(ji)、煤炭及其它黏(nian)性(xing)(xing)大的(de)物料。该机(ji)采用激(ji)振器(qi)为筛(shai)(shai)(shai)(shai)机(ji)提供激(ji)振力，通过(guo)倾斜筛(shai)(shai)(shai)(shai)箱上(shang)安(an)装的(de)弹(dan)性(xing)(xing)筛(shai)(shai)(shai)(shai)面(mian)(mian)的(de)弛、张运动(dong)抛掷物料的(de)筛(shai)(shai)(shai)(shai)分(fen)机(ji)。其主(zhu)要特(te)点是筛(shai)(shai)(shai)(shai)分(fen)效率(lv)提高，处理量大，动(dong)负荷小，功耗少，噪声低，因此应(ying)用较为广泛。在(zai)这个过(guo)程中，弹(dan)性(xing)(xing)聚氨酯筛(shai)(shai)(shai)(shai)面(mian)(mian)以每(mei)分(fen)钟(zhong)800次的(de)频(pin)率(lv)连(lian)续(xu)不断地扩张、收缩，有效地防(fang)止了(le)筛(shai)(shai)(shai)(shai)孔堵塞。

优势特点

弛张筛产品优势

1、由于筛面做弛(chi)张运动(dong)能(neng)够传递给物(wu)(wu)料加速度，所以(yi)能(neng)够筛分(fen)难筛物(wu)(wu)料，筛孔(kong)不容(rong)易堵塞。

2、入料(liao)(liao)端物(wu)料(liao)(liao)速度(du)快、料(liao)(liao)层薄，大量(liang)物(wu)料(liao)(liao)透(tou)筛(shai)(shai)，处理量(liang)高。排料(liao)(liao)端筛(shai)(shai)面倾角(jiao)低，物(wu)料(liao)(liao)速度(du)慢，这得以将剩余的(de)筛(shai)(shai)下物(wu)彻底透(tou)筛(shai)(shai)，达到(dao)非常高的(de)筛(shai)(shai)分(fen)效率。

3、线性(xing)运动的箱式激振器可靠性(xing)高、维护简单。

4、弛张(zhang)筛的(de)聚氨酯(zhi)筛板(ban)(ban)是特殊(shu)设计的(de)，以承(cheng)受50g的(de)振动强度以及每分钟800次的(de)曲张(zhang)，筛板(ban)(ban)使用寿(shou)命(ming)长、筛机坐落在空心的(de)橡(xiang)胶(jiao)弹簧上，产生的(de)噪音小(xiao)，而且橡(xiang)胶(jiao)弹簧寿(shou)命(ming)长。

5、筛(shai)分机(ji)侧部“U”形(xing)设计(ji)以形(xing)成密封，侧板(ban)无(wu)磨损，而且防止了筛(shai)上物进入筛(shai)下、筛(shai)板(ban)用楔形(xing)橡胶条固(gu)定，不需要任何螺栓，拆装(zhuang)方便、快(kuai)捷、筛(shai)分机(ji)转动部件(jian)少，运(yun)行可靠性高(gao)(gao)，日常维护工作量少，利(li)用率高(gao)(gao)、浮动筛(shai)框(kuang)振幅可调(diao)驰张筛(shai)。

工作原理

弛张筛工作原理

弛张筛(shai)(shai)(shai)(shai)(shai)(shai)是双质(zhi)(zhi)(zhi)量振(zhen)(zhen)动(dong)(dong)(dong)系统，采用聚氨酯(zhi)筛(shai)(shai)(shai)(shai)(shai)(shai)面(mian)，支(zhi)承筛(shai)(shai)(shai)(shai)(shai)(shai)面(mian)的(de)任意两(liang)(liang)根(gen)相邻横(heng)(heng)梁(liang)都分别属于两(liang)(liang)个(ge)振(zhen)(zhen)动(dong)(dong)(dong)质(zhi)(zhi)(zhi)体，其中一个(ge)质(zhi)(zhi)(zhi)体是筛(shai)(shai)(shai)(shai)(shai)(shai)箱(xiang)(xiang)，另一个(ge)质(zhi)(zhi)(zhi)体是配重。在工作时(shi)，筛(shai)(shai)(shai)(shai)(shai)(shai)网交替地拉(la)紧(jin)和松(song)弛，使(shi)(shi)物料(liao)产生前进弹(dan)跳运(yun)动(dong)(dong)(dong)，可避(bi)免物料(liao)黏附(fu)筛(shai)(shai)(shai)(shai)(shai)(shai)网并(bing)堵塞(sai)筛(shai)(shai)(shai)(shai)(shai)(shai)孔。当(dang)两(liang)(liang)质(zhi)(zhi)(zhi)体相差二(er)相位(wei)振(zhen)(zhen)动(dong)(dong)(dong)时(shi)，任意两(liang)(liang)根(gen)相邻横(heng)(heng)梁(liang)时(shi)而靠近，时(shi)而远离，弹(dan)性筛(shai)(shai)(shai)(shai)(shai)(shai)面(mian)也相应(ying)时(shi)而松(song)弛，时(shi)而张紧(jin)，即筛(shai)(shai)(shai)(shai)(shai)(shai)面(mian)随筛(shai)(shai)(shai)(shai)(shai)(shai)箱(xiang)(xiang)作牵连(lian)运(yun)动(dong)(dong)(dong)的(de)同时(shi)，还相对(dui)筛(shai)(shai)(shai)(shai)(shai)(shai)箱(xiang)(xiang)作相对(dui)运(yun)动(dong)(dong)(dong)。这种弛张运(yun)动(dong)(dong)(dong)不仅使(shi)(shi)筛(shai)(shai)(shai)(shai)(shai)(shai)孔不断产生变形(xing)(xing)，而且(qie)大(da)大(da)增加了筛(shai)(shai)(shai)(shai)(shai)(shai)面(mian)的(de)振(zhen)(zhen)动(dong)(dong)(dong)强度，从而有(you)效地克服了筛(shai)(shai)(shai)(shai)(shai)(shai)孔堵塞(sai)现象，显著提高了筛(shai)(shai)(shai)(shai)(shai)(shai)机处理能力。但是因筛(shai)(shai)(shai)(shai)(shai)(shai)箱(xiang)(xiang)的(de)振(zhen)(zhen)动(dong)(dong)(dong)强度并(bing)不大(da)，故机械强度容易保证(zheng)，但筛(shai)(shai)(shai)(shai)(shai)(shai)面(mian)的(de)振(zhen)(zhen)动(dong)(dong)(dong)强度较大(da)且(qie)反复(fu)变形(xing)(xing)，故筛(shai)(shai)(shai)(shai)(shai)(shai)面(mian)寿命较低。
