叠螺污泥浓缩机

叠螺污泥浓缩机继承了叠螺污泥脱水机的低能耗,高效率,全自动控制,运行稳定等技术优点,可直接将二沉池污混快速续浓缩,且浓缩分离后的污泥浓度在90%~96%范围内稳定可调,采用该设备后无需建设浓缩池,减少建设投资和占地,有效减少浓缩池污泥造成的恶臭和磷释放,降低后续处理的工作负担,并大幅度提高污泥脱水和深度脱水设备的产能。

sludge thickening screw press inherits the technical advantages of sludge dewatering screw press and developed its own advantages, such as low energy consumption, nigh efficiency, fully automatic control, and stable operation. it can directly thickenthe sludge in the secondary sedimentation tank quickly and continuously, and the sludge concentration is stable and adjustable in the range of 90-96%. after using tinis equiprient, thickening tark is not needed any more, which reduces construction ost and land space. furthermore, it can effectively reduce the odor and phosphcorus release caused by the sludge in the thickening tank, release the workload of subsequent treatments, and significantly increase the capacity of sludge dewatering equipment.


设备原理

work principle

叠螺污泥浓缩机由浓缩主体、驱动装置、滤液槽、混合系统、架体等组成。叠螺污泥浓缩机工作时,通过污泥泵将污泥提升至混合槽后,此时,加药泵也定量地对混合精输送药液,微样电机带动整个搅拌系统将污泥与药液进行充分混合,从而产生矾花,当液位达到液位传感器得到信号,使得叠螺主体电机工作,从而开始压滤流入至叠螺主体内污泥,在螺旋轴的作用下,将污泥一步一步提升至污泥出口,满液则从固定环和游动环之间的间隙中流出来。

总的来说,叠螺污泥浓缩机是运用了螺杆挤压原理,通过螺杆直径和螺距变化产生的强大挤压力,以及游动环与固定环之间的微小缝隙,实现对污泥进行挤压浓缩的一种新型的固液分离设备。

the sludge thickening screw press is composed of a thickener, a driving device, a filttate tank, a mixing system, and a frame. when the screw press is working, the sludge is purnped to ihe rousing tark by the sudge purmp, in the mean time, the dosng pumq aiso guanttatively transports the polmer to the mixing tank, then the stirrina motor drives agitator to start mixing untl solid particles are floculated. when the liquid level reaches the upper level of the fiquid level sensor, the sersor gets a sigrwl and instructs the main motor of screw press to work, thereby starting to filter and press the sludge that comes into the screws body. under the squeezing of the screw shaft, the sludge is raised step by step to the sludge outlet, and the filtrate flows out from the gap between the fixed ring and the moving ring.

in general the sludge thickener screw press uses the principle of screw extrusion which is finalized by the strong extrusion force from the change of screw diameter and pitch, and the tiny gap between the rroving ring and the fixed ring, thus the sold andliguid can be separated. sluckenthickening screw press is a new type of solick-licuid separationequipment for sludge concentration.
