设备简介

Instructions

叠螺污泥脱水机适用于市政污水、食品、饮料、化工、皮革、焊材、造纸、印染、制药等行业的污泥处理，尤其适用于处理油性含量高的污泥。

运行费用低，低速螺旋挤压技术，使得耗电量大幅度降低；设备不易堵塞，冲洗用水大幅度减少；24小时全自动无人运行，人工费用大幅度降低。

在相同处理量的情况下，叠螺机用水量仅为带机的约1/80；叠螺机用电量仅为离心机的约1/12

连续自动运行，叠螺污泥脱水机从泵送污泥，加入药液，排出泥饼均采用自动控制，通过电控柜，加药装置，进泥泵，加药泵等进行联动，可实现24小时无人运行。

Screw filter is mainly used in wastewater treatment industries, such as: municipal wastewater, waster water from food, beverage, chemical, leather, and sludge treatment in papermaking, printing and dyeing, pharmaceutical and other industries.Especially suitable for treating sludge with high oil content.

Because of screw squeezing technology, the power consumption is very low, so that save running cost. It's difficult to be blocked, so the quantity of washing waster will be greatly decreased. It can running continuously for 24 hours, so it has feature of lowest labour cost.

Under the same situation, the water consumption is only 1/80 of the belt filter press and the power consumption is only 1/12 of the centrifuge machine.

Fully automatic running. From feeding, adding chemicals to cake discharging, all steps can be controlled automatically and can contentiously run for 24 hours.

产品特点

Features

叠螺体包括若干相互叠置的固定环，固定环的外周均布有多个螺杆，固定环套装在螺杆上，螺杆上位于相邻两固定环之间套置有垫圈，相邻固定环之间的间隙中还设置有游动环，固定环的内侧与螺旋叶片间隙配合。工作时，游动环随螺旋轴（主轴）的转动而游动，垫圈使得固定环和潜动环之间始终能保持一定的间隙，避免完全堵死，具有自清作用，无需为防止消止消止消息而大量清洗，彻底减少了冲洗用水量。高效污泥挤压技术∶为了进一步降低最终滤饼的含水率。我们采用了独特结构∶

一：是螺旋叶片的螺距从进泥箱向排泥箱方向上逐渐减小，同时螺旋轴靠近排泥箱一侧设有一段变径段，变径段的直径从进泥箱向排泥箱方向上逐渐变大。

二：是在主轴上，位于排泥箱内设有阻混板，阻混板与脱水筒之间留有问隙。阻泥板的设置可阻挡污泥，使脱水筒内的污泥具有一定的压力，可将污泥中的水充分挤出，达到更好的脱水效果。

叠螺体自清洗技术

三：是煤液叶片的表面硬化处理技术在螺旋轴叶片外径上利用低温超音速技术进行表面喷涂硬质材料，使表面硬度达到1000HV，附着力大于70MPa，工件变形小，减少了对螺旋轴杆片的磨损，延长了叠螺体的使用寿命。一般部件采用裁板机或者水刀切割，关键部件纯激光下料，保证设备高精确度。

The screw body is consist of fixed rings, movable rings, screw bars, gasket and the main screw. Whileworking, the movable rings will move as a cycle around the main screw, however, the gasket ensures there have some gap between the fixed ring with the movable ring, so that avoid block torealize self-washing function, and thus greatlydecrease the consumption of washing waster. High Efficient Sludge Squeezing Technology: to greatly deceatse the final cake moisture, we adopts three special structures:

1.The screw distance is decreasing from inlet (bottom side) to outlet (top side). At the same time, the diameter of the screw is becoming bigger from inlet to outlet.

2.On the main shaft, in the cake discharging tank,there is a baffle and there is a gap between the balffle with the dewatering roller, so the ensure therewill have some pressure to the sludge. Thus it can perfectly squeeze out the water and realize best filtering performance.

3.Screw Induration Technology: On the surface ofthe screw leaf, it is processed by the induration materials, and this ensures the hardness can be 1000 HV and the adhesive force is bigger than 70 MPa, so It's difticult to cause deformation, and can have long life-span. Four filter, the normal parts are cut by cutting machine or water cutting machine, and the key parts are cut by laser to make sure the precision.
