叠螺式污泥脱水机
Sludge Dewatering Screw Press
节电、节水、PLC全自动运行！
产品概况Introduction
叠螺式污泥脱水机是集全自动PLC控制柜、污泥浓缩脱水本体及絮凝箱于一体，可在全自动运行的条件下，实现高效的絮凝，连续完成污泥浓缩压榨脱水工作，将收集的滤液回流或排放，脱水的污泥排出。
叠螺式污泥脱水机的主体是由多重固定环及垫圈和游动环组成，螺旋轴贯穿其中形成过滤装置，前段为浓缩部分，后段为脱水部分，将污泥的浓缩和压榨脱水在一起完成，以*微妙的滤体结构取代了传统的滤布和离心的过滤方式。
The laminated screw sludge dewaterer integrates automatic PLC control cabinet, sludge concentrating and dewatering body and flocculation box. It can realize efficient flocculation under the condition of full automatic operation, continuously complete sludge concentrating and pressing dewatering, return or discharge the collected filtrate, and discharge the dewatered sludge.
The main body of the laminated screw sludge dewaterer is composed of multiple fixed rings, washers and swimming rings. The helical shaft runs through the filter to form a filtering device. The front section is the concentrated part, and the back section is the dewatering part. The sludge is concentrated and pressed together to complete dewatering. The unique and subtle filter structure replaces the traditional filter distribution and centrifugal filtration. Way.
空心桨叶干燥机
Hollow Paddle Dryer
污泥干化含水率降至30%以下！
产品概况Introduction
空心桨叶干燥机是一种以传导为主的卧式搅拌型干燥机。因内部空心的搅拌叶片形似于船桨，固称之为空心桨叶干燥机。主体结构为带有夹套的W型壳体内装有成对的空心低速回转中空轴，轴上焊有若干搅拌叶片，夹套和空心搅拌叶片，其内均通以热载体，两种加热面同时对物料加热。空心轴上密集排列着楔形中空桨叶，热介质经空心轴流经桨叶。单位有效容积内传热面积很大，热介质温度从-40~320°C，可以是水蒸气，也可以是液体型：如热水、导热油等。间接传导加热，没有携带空气带走热量，热量均用来加热物料，热量损失仅为通过器体保温层向环境的散热。楔形桨叶传热面具有自清洁功能，物料颗粒与楔形面的相对运动产生洗刷作用，能够洗刷掉楔形面上的附着物料，使运动中一直保持着清洁的传热面。它适合颗粒状及粉末物料的干燥，对膏状物料也能顺利的进行干燥。（其中针对污泥干燥的行业有：印染、造纸、制药、生物、电镀、热电、化工及污水处理厂。一般污泥脱水前（初水份在60%-90%），烘干后终水分为10%-40%，一般污泥要求在30%左右，干污泥成松散粉粒状可与煤粉混合后直接进入锅炉燃烧，污泥的热值大概在1500-2000kcal左右，可废物利用并节省能源，有的污泥烘干后也可制成肥料和建筑材料，或直接填埋不会造成二次污染，变废为宝，*可达到环保要求）
The hollow paddle dryer is a horizontal agitating dryer with conduction-oriented. Because the inner hollow mixing blade is shaped like a boat paddle, it is called a hollow paddle dryer. The main structure is a W-shaped shell with a jacket, which is equipped with a pair of hollow low-speed rotating hollow shafts. A number of stirring blades, jackets and hollow stirring blades are welded on the shaft, and a heat carrier is passed through them. Two heating surfaces At the same time, the material is heated. Wedge-shaped hollow blades are densely arranged on the hollow shaft, and the heat medium flows through the blades through the hollow shaft. The heat transfer area in the unit effective volume is large, and the temperature of the heating medium ranges from -40 to 320°C. It can be steam or liquid: such as hot water, heat transfer oil, etc. Indirect conduction heating does not carry air to take away heat. The heat is used to heat the material, and the heat loss is only the heat dissipation to the environment through the insulation layer of the body. The heat transfer surface of the wedge-shaped blade has a self-cleaning function, and the relative movement of the material particles and the wedge-shaped surface produces a scrubbing effect, which can wash off the attached material on the wedge-shaped surface, so that a clean heat transfer surface is always maintained during movement. It is suitable for drying granular and powder materials, and can also dry paste materials smoothly. (Among the industries for sludge drying are: printing and dyeing, papermaking, pharmaceuticals, biological, electroplating, thermal power, chemical and sewage treatment plants. Generally, the sludge is dewatered (initial moisture is 60%-90%), and the final moisture after drying It is 10%-40%, and the general sludge requirement is about 30%. The dry sludge can be mixed with pulverized coal and then directly burned in the boiler. The calorific value of the sludge is about 1500-2000kcal, which can be used and saved. Energy, some sludge can also be dried into fertilizer and building materials, or directly landfilled will not cause secondary pollution, turn waste into treasure, and fully meet environmental protection requirements)
