Features and application of shaft-less screw conveyor

As a new type of transport machine emerging in recent years, the shaft-less screw conveyor adopts the design of shaft-less, with unique structure. It is mainly composed of motor, reducer, mechanical seal, flexible shaft-less screw, u-shaped groove and protective bushing, etc. Other supporting accessories include supporting legs, cover plate, end cover and flange.

Advantages of shaft-less screw conveyor in practical application

Compared to a belt conveyor

(1) Since U groove, supporting leg, cover plate and other parts are made of stainless steel, they are beautiful in appearance, compact in structure and small in occupation area.

(2) The overall structure is relatively simple with few parts. The u-shaped groove adopts sectional flange connection, which is convenient to replace and repair the inner bushing. Therefore, the whole machine runs safely and reliably, and the maintenance is convenient. Due to the friction of the shaft-free spirals and u-shaped groove protective lining materials are high wear resistance materials, and with low spiral speed, small wear, long service life and low maintenance costs.

(3) If the dehydrated sludge accidentally falls into the feeding port, it will not cause any scattering or leakage and will not pollute the environment. In addition, since the upper part of u-shaped trough is equipped with cover plate, the conveying process basically belongs to airtight transportation, so it can effectively reduce indoor peculiar smell.

(4) In the normal operation process, maintenance and adjustment are basically unnecessary, which can effectively reduce the labor intensity of operators.

Technical features of shaft-less screw conveyor

Compared with the traditional screw conveyor with shaft, the screw conveyor without shaft has the following prominent advantages:

1.Shaft-less screw conveyor winding resistance is strong, because there was no central axis, the conveyor belt, viscous material, easy to winding material has special advantages, such as used in sewage treatment plants conveying fine screen, its net bars from 50 mm decontamination machine grid slag and filter press mud cake or other materials, or waste disposal sites processing of waste, to prevent obstruction caused by the accident.

2.Shaft-less screw conveyor has good environmental performance. The shaft-less screw conveyor adopts the spiral surface that is fully closed and easy to clean, which can guarantee the environmental sanitation and the materials delivered are free from pollution and leakage.

3. Large torque distance and low energy consumption of shaft-less screw conveyor. As the screw has no shaft, the material is not easily blocked, and the discharge port is not blocked, so it can operate at lower speed, smooth transmission and reduce energy consumption. The torque can be 4000N/m.

4. Large conveying capacity of shaft-less screw conveyor. The conveyance capacity of shaft-less screw conveyors is 1.5 times of conventional screw conveyors with shafts of the same diameter.

5. Long conveying distance of shaft-less screw conveyor. Individual conveyor length up to 60 meters. And according to the needs of the user, the use of multi-stage tandem installation, ultra long distance transport of materials.

6. Flexible operation of shaft-less screw conveyor. Our company develops and produces a mobile screw conveyor without shaft, which can work flexibly. Can through the bottom unloading the material, and through the top unloading the material. Using lining board, the machine can work under high temperature. Compact structure, space - saving, beautiful appearance, easy operation, economical and durable.
