Description

一种通过动态进料通道进泥的污泥脱水方法及板框(厢式)脱水机 技术领域
本发明涉及污泥脱水设备领域技术领域,具体来说是一种通过动态进料通道进泥的污泥脱水方法及板框(厢式)脱水机。
背景技术
厢式或板框脱水机是一种实现固液分离的设备,现有常见的脱水机将带有滤液通路的滤板平行排列,滤板和相邻滤板之间夹有滤布,将滤板压紧,使滤板与相邻滤板之间构成一个压滤室,悬浮液不断泵入压滤机的滤室内,滤渣被截留在滤室内形成滤饼,滤液透过滤布从滤板的排液通道中流走。待泵达到设定压力之后停止进料,此时如需进一步降低滤饼含水率需对滤饼进行二次挤压,二次挤压时间到之后就开滤板卸滤饼,卸完滤饼后对滤布完成冲洗,后续再合板,等待下一次进泥。由于滤饼具有粘附性,滤饼往往不会全部脱落,很多会粘黏在滤布上。这就需要工人辅助铲落滤饼。另外传统的厢式或板框脱水机是通过滤板上的隔膜充入高压水或空气对滤饼进行二次挤压的,二次挤压压力一般在15kg/CM2左右,二次压榨压力不足,对后续的脱水流程造成影响。
发明内容
本发明的目的在于解决现有技术的不足,提供一种无需人工铲泥,并具有更高二次挤压压力的一种通过脱水机动态进料通道的污泥脱水方法。
同时,为了实现上述目的,还设计了一种具有动态进料通道的脱水机
本发明采用的技术方案如下:
一种通过脱水机动态进料通道的污泥脱水方法,包括以下步骤:
S1.由弹性进料口与滤布夹以及滤布夹上的单位泥饼注入孔共同组成动态进料通道;
S2.污泥由进料泵泵入所述动态进料通道,当动态进料通道内压力到达一定数值时停止进料;
S3.主油缸推动所述动态进料通道两侧的滤板,将两块滤板之间泥饼内的水分进一步挤压去除,进一步降低滤饼含水率;在滤板再次靠近时,进料通道需要同步被压缩,该压缩过程通过动态进料通道的弹性进泥口的压缩变形实现。
S4.打开滤板,通过与所述滤布连接的滤布牵引装置拉动滤布,使滤饼从所述滤布上脱落。由于进料通道的进料口和滤布夹在开板后是分开的,这时候滤布上下行走时滤布夹是可以同步移动的,有效结合了滤布上下行走和滤饼弹性二次挤压两种功能。
进一步的,所述步骤S2中,当所述动态进料通道内的压力为6-10kg/cm2时(泥饼收到的压强),停止进料。
进一步的,所述步骤S3中,推动所述动态进料通道两侧滤板的压力大于等于30kg/cm2(泥饼受到的二次挤压压强)。
本发明的另一方面,提供了一种具有动态进料通道的脱水机,包括弹性进料口和滤布,所述弹性进料口与所述滤布夹组成动态进料通道,所述弹性进料 口与进料泵连接,所述滤布与滤布牵引驱动装置连接,所述动态进料通道两侧设有滤板,所述滤板与主油缸连接。
进一步的,所述滤板上方和下方均设有滤布密封装置。
进一步的,所述滤板靠近是同步压缩进料通道中的弹性进料口的。
进一步的,所述脱水机可以包括由若干弹性进料口与滤布夹组成的动态进料通道。
发明的有益效果
本发明所提供的一种通过脱水机动态进料通道的污泥脱水方法的优点包括但不限于:既能够实现可变滤室的超高压二次压榨技术,又能够实现滤布的上下移动,自动落泥,不需要人工辅助落泥,而且由于污泥含水率大大下降,为污泥后续处理处置提供了有利条件,大大节约了后续污泥处理处置的投资和运行成本,具有巨大的社会效益。

具体实施方式
下面结合附图,对本发明所采用的技术方案做进一步说明。
如图1~3所示,为本发明一种具有动态进料通道的脱水机的一种实施例,结合图1~3,对本实施例的工作原理作进一步的说明。
如图1所示,在进行二次挤压前的状态下,由弹性进料口1和滤布夹5交替压紧组成了进料通道,然后污泥由进料泵泵入进料通道1,当压力达到一定值后,一般是6-10kg/cm2时,停止进料,此时,主油缸进行二次动作,向内侧推动所有滤板靠紧,每两块滤板之间形成的滤室厚度不断变薄,滤布2内的滤饼6受到越来越大的挤压力,滤饼6中的水被再次挤压出来,滤饼厚度由图1中的B1减小到图2中的B2,同样弹性进料口也被压缩了,压缩的长度为B1-B2。此时二次加压压力可以达到30kg/cm2以上,相较于隔膜二次挤压滤饼的方式,其挤压力多了将近一倍。当主油缸到达预先设计的位置后,对滤板保压一段时间后主油缸再次动作后退,拉动滤板逐片同步打开(如图3所示),然后滤布2通过滤布牵引驱动装置上下移动,带动滤饼6往下移动,所有粘连在滤布上的滤饼会受到重力影响自动脱落,这样可以不需要人工辅助铲泥了。通过以上的结构形式和工艺流程能够很好地实现滤布自动落泥和可变滤室厚度超高压二次挤压。
同时,本发明还提供一种通过脱水机动态进料通道的污泥脱水方法,其特征在于,包括以下步骤:
S1.由弹性进料口与滤布夹共同组成动态进料通道;
S2.污泥由进料泵泵入所述动态进料通道,当动态进料通道内压力到达一定数值时停止进料;
S3.主油缸推动所述动态进料通道两侧的滤板,将滤布之间(滤板之间)的污泥挤压为滤饼;
S4.打开滤板,通过与所述滤布连接的滤布牵引装置拉动滤布,使滤饼从所述滤布上脱落。
综上所述,本发明的有益之处在于,既能够实现可变滤室的超高压二次压榨,又能够实现滤布的上下自动落泥,不需要人工辅助落泥。这样就能够推动厢式或板框压滤机的进一步升级换代,不仅解决了需求,而且由于污泥含水率大大下降,为污泥后续处理处置提供了有利条件,大大节约了后续污泥处理处置的投资和运行成本,具有巨大的社会效益。
以上所述,仅为此发明的具体实施方式,但本发明的保护范围不局限于此,任何熟悉本技术领域的技术人员在本发明揭露的技术范围内,根据本发明的技术方案和新型的构思加于等同替换或改变,都应涵盖在本发明的保护范围之内。
