A good conveyor for transporting sludge should use a shaftless screw conveyor, which is characterized by strong adhesion and viscous paste like materials. Such as sludge in sewage, high moisture content slag, etc.
The scaling characteristics of shaftless spiral:
U-shaped section: The external structural dimensions are basically the same as those of the LS series screw conveyor.
Axial free spiral: The spiral body is a thick strip spiral, with no axial rotation axis, and the head is connected to the drive shaft. Structurally, there are two types of blades: single blade and double blade. In terms of material, there are two types: carbon steel and stainless steel. According to the pitch ratio, there are two types: 1:1 and 2:3.
Sliding lining plate: a working support component for the middle and tail of the shaftless spiral body, which is made of high-strength engineering plastics, stainless steel, and other high wear-resistant materials.
It can also be designed based on the provided information. According to different materials, there is also a type of circular tube casing with good sealing performance, which can achieve airtightness (0.02mpa) and can work under positive and negative pressure conditions.
Characteristics of sludge screw conveyor:
1. Large conveying capacity, allowing for the transportation of large amounts of materials in small capacity spaces, with a conveying capacity of 15-500m3/h.
2. Low energy consumption during transportation, utilizing the internal friction of materials, saving 40% to 60% electricity compared to screw conveyors.
3. Sealed and safe, the fully sealed casing makes dust seamless and drillable, ensuring safe operation and reliable performance.
4. Long service life, the conveyor chain made of alloy steel through advanced heat treatment processing has a normal service life of>3 years, and the roller life on the chain (depending on different materials) is 1-3 years.
5. The conveying length is long, and the horizontal conveying distance can reach over 60 meters.
6. The process layout is flexible, and it can be installed on elevated, ground, pit, and uphill (15) platforms, with multiple points for material entry and exit.
7. Low usage cost, energy-saving and durable, extremely low maintenance rate, reducing consumption and improving efficiency
The sludge screw conveyor is mainly used to transport sludge, slag, etc. The conveying direction of the conveyor is determined by the spiral direction of the spiral blades and can be transported in both directions. This conveyor can be transported in a closed manner to prevent environmental pollution. It can be conveyed horizontally or obliquely, and when conveying materials, the scraper chain is completely buried in the material. This machine has the advantages of simple structure, reliable use, low cost, long conveying distance, and the ability to transport hot materials. It is widely used in departments such as building materials, chemical industry, metallurgy, coal, mining, and machinery.
