Product features

The product is mainly used in the chemical, food, pharmaceutical, papermaking, beverage, environmental protection and other industries to convey materials with strong adhesion, pasty and viscous materials (such as chemical raw materials, waste paper pulp, malt, sludge, etc.) and easily entangled materials (such as domestic garbage).

Working principle

The XDH type shaftless screw conveyor has a conveying principle basically the same as that of a general screw conveyor: just like a rotating screw shaft driving a nut to move along its axial direction, the screw body is equivalent to the screw shaft and the material is equivalent to the nut. When the screw body rotates continuously, the material is also conveyed continuously. The shaftless screw conveyor has a relatively thick strip-shaped blade as its screw body, which is driven by the drive end shaft. There is no shaft in the middle, and the screw body comes into contact (slides) with the bottom liner of the inner wall of the casing.

Compared with the traditional shafted screw conveyor, the shaftless screw conveyor, due to its design without a central shaft and the use of an integral steel screw with certain flexibility to push materials, has the following outstanding advantages: strong anti-entanglement performance. Without the interference of a central shaft, it has special superiority in conveying strip-shaped and easily entangled materials. The application of the shaftless screw conveyor: The XDH series shaftless screw conveyor is used in sewage treatment plants to convey the screen residue of the medium and fine screen with a clear distance of 50mm between the bars and the mud cake of the filter press, etc. It has good environmental protection performance. The fully enclosed conveying and the easy-to-clean spiral surface can ensure environmental hygiene and prevent the conveyed materials from being contaminated or leaked. High torque and low energy consumption. As the screw has no shaft, the material is not prone to clogging, and the discharge port is not clogged. Therefore, it can operate at a lower speed, with smooth transmission and reduced energy consumption. The torque can reach 4000N/m. Large conveying capacity. The conveying capacity is 1.5 times that of the traditional shafted screw conveyor of the same diameter. The conveying distance is long. The single-machine conveying length can reach up to 60 meters. And according to the user's needs, it can be installed in a multi-stage series to convey materials over an extremely long distance. It can work flexibly. The mobile shaftless screw conveyor developed and produced by our company can operate in a mobile manner and serve multiple purposes with one machine. It can be discharged either from the bottom or from the end. This machine can operate at high temperatures by using specially made liners. Compact structure, space-saving, beautiful appearance, easy operation, economical and durable.

Compared with the traditional shafted screw conveyor, the shaftless screw conveyor, due to its design without a central shaft and hanging bearings, uses an integral steel screw with certain flexibility to push materials, thus having the following outstanding advantages:

1. The spiral has extremely strong wear resistance and durability, with a long service life.

2. Strong anti-entanglement performance: Without the interference of a central shaft, it has special superiority in conveying strip-shaped and easily entangled materials, preventing blockage and causing accidents.

3. Good environmental performance: It adopts fully enclosed conveying and an easy-to-clean spiral surface, which can ensure environmental hygiene and prevent the conveyed materials from being contaminated or leaking.

4. High torque and low energy consumption: As the screw has no shaft and the material is less likely to get clogged, it can operate at a lower speed, ensuring smooth transmission and reducing energy consumption.

5. Large conveying capacity: The conveying capacity is 1.5 times that of traditional shafted conveyors of the same diameter, with a maximum of 40m ³ /h. The conveying distance is long, up to 25 meters, and it can be installed in a multi-stage series according to the user's needs to convey materials over an extremely long distance.

6. Compact structure, simple operation, economical and durable, and low maintenance.
