Sludge conveying equipment plays a crucial role in sewage treatment. Sludge conveying equipment can transport sludge from production or treatment sites to treatment equipment, storage facilities, or subsequent disposal points. Common sludge conveying equipment includes belt sludge conveyors and sludge screw conveyors
1、 Technical principle of sludge conveying equipment
The working principle of sludge conveying equipment mainly relies on mechanical transmission and fluid mechanics principles. Common sludge conveying equipment includes belt conveyors, screw conveyors, scraper conveyors, and sludge conveying pumps. These devices transport sludge from one location to another through different mechanical structures and power devices.
1. Belt conveyor
Belt conveyor is a mechanical device driven by friction to transport materials continuously. It transports sludge from the production or processing site to processing equipment, storage facilities, or subsequent disposal points through the friction between the conveyor belt and the driving drum. Belt conveyors have the advantages of large conveying capacity, simple structure, easy maintenance, low cost, and strong versatility.
2. Spiral conveyor
The screw conveyor transports sludge from one end to the other through the rotation of the spiral blades. Its compact structure and strong resistance to entanglement are suitable for transporting granular or powdery sludge, commonly used in sewage treatment and sludge treatment processes. Spiral conveyors are particularly suitable for horizontal or inclined conveying, especially for sludge with high viscosity.
3. Scraper conveyor
The scraper conveyor drives the scraper through a chain to transport sludge from one end to the other. The main structure is made of stainless steel material, which has high mechanical strength, strong corrosion resistance, and long service life. Scraper conveyor is particularly suitable for conveying high concentration and high viscosity sludge, which can effectively prevent blockage.
4. Sludge transfer pump
The working principle of the sludge conveying pump mainly relies on the reciprocating motion of the piston of the oil pump, which drives the reciprocating motion of the working cylinder to achieve the feeding and discharging of sludge. The core component is a twisted blade rubber cam rotor pump, which uses two spiral cam rotors that continuously rotate under synchronous gear drive to push the conveying medium from the pump inlet to the pump outlet.
2、 Application fields of sludge conveying equipment
Sludge conveying equipment is widely used in various fields, including sewage treatment, petroleum, chemical, metallurgical, and food industries.
