疊螺污泥濃縮機(jī)

疊螺污泥濃縮機(jī)繼承了疊螺污泥脫水機(jī)的低能耗，高效率，全自動(dòng)控制，運(yùn)行穩(wěn)定等技術(shù)優(yōu)點(diǎn)，可直接將二沉池污混快速續(xù)濃縮，且濃縮分離后的污泥濃度在90%~96%范圍內(nèi)穩(wěn)定可調(diào)，采用該設(shè)備后無(wú)需建設(shè)濃縮池，減少建設(shè)投資和占地，有效減少濃縮池污泥造成的惡臭和磷釋放，降低后續(xù)處理的工作負(fù)擔(dān)，并大幅度提高污泥脫水和深度脫水設(shè)備的產(chǎn)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.

設(shè)備原理

Work Principle

疊螺污泥濃縮機(jī)由濃縮主體、驅(qū)動(dòng)裝置、濾液槽、混合系統(tǒng)、架體等組成。疊螺污泥濃縮機(jī)工作時(shí)，通過污泥泵將污泥提升至混合槽后，此時(shí)，加藥泵也定量地對(duì)混合精輸送藥液，微樣電機(jī)帶動(dòng)整個(gè)攪拌系統(tǒng)將污泥與藥液進(jìn)行充分混合，從而產(chǎn)生礬花，當(dāng)液位達(dá)到液位傳感器得到信號(hào)，使得疊螺主體電機(jī)工作，從而開始?jí)簽V流入至疊螺主體內(nèi)污泥，在螺旋軸的作用下，將污泥一步一步提升至污泥出口，滿液則從固定環(huán)和游動(dòng)環(huán)之間的間隙中流出來。

總的來說，疊螺污泥濃縮機(jī)是運(yùn)用了螺桿擠壓原理，通過螺桿直徑和螺距變化產(chǎn)生的強(qiáng)大擠壓力，以及游動(dòng)環(huán)與固定環(huán)之間的微小縫隙，實(shí)現(xiàn)對(duì)污泥進(jìn)行擠壓濃縮的一種新型的固液分離設(shè)備。

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.
