The spiral pipe conveyor is welded with continuous spiral blades in the cylindrical shell, which rotates with the spiral blades. Join materials due to the action of the centrifugal force and friction force with casing rotation and promotion, in the material under the action of gravity and slide along the spiral surface, make the material with spiral pipe rotation so as to realize the material to move forward, like not rotating along the rotation of screw nut for translational motion, to achieve the purpose of conveying material.

Low energy consumption and low maintenance cost; When feeding at the end, it can meet the requirements of uneven feeding, and can complete various technological requirements such as conveying, mixing and so on at the same time. When the material enters too much, it will not produce stuck phenomenon. Convenient for multi-point loading and unloading, conveying materials with high temperature. Suitable for horizontal conveying of high temperature materials; It has good adaptability to high temperature, non-uniform material supply, materials with anti-breakage requirements and anti-pollution requirements, and processes requiring multi-point loading and unloading. It has been proved in practice that the transportation of cement clinker, dry limestone, phosphate rock, ilmenite powder, coal and slag is effective.

The particle size of the material added by the feed inlet at the end shall not be greater than 1/4 spiral diameter; The size of the material fed from the intermediate feed inlet shall not be greater than 30 mm. The feeding temperature must be controlled below 300℃ to ensure that the cylinder does not deform. The wear of the blade and the material groove is very serious when the machine is transporting the material with great abrasives. The spiral conveyor designed in this paper mainly USES and transports silicon micro powder, which has great grinding property, so it is not suitable to use spiral pipe conveyor.

The working principle of

When the screw axis rotates, the material can only move forward along the trough bottom of the conveyor under the push of the blades due to the gravity of the material and the friction generated between the material and the trough wall, just as the nut that cannot be rotated can move along the translational motion of the rotating screw. The transport of materials in the intermediate bearing depends on the thrust of advancing materials behind. Therefore, the transport of materials in the conveyor, is a complete slip movement. In order to make the screw shaft in a more favorable tensile state, the driving device and the unloading port are generally placed on the same end of the conveyor, and the feeding port is placed as far as possible near the tail of the other end. The force that the rotating spiral blade moves the material so that the material does not rotate with the spiral conveyor blade is the weight of the material and the friction resistance of the spiral conveyor casing to the material. There are solid surface, belt surface and blade surface according to different conveying materials. The screw shaft of the screw conveyor has thrust bearing at the end of the direction of the material movement in order to give the axial reaction force to the screw with the material, in the long, should add the intermediate hanging bearing.

Screw machine is widely used in various industries, such as building materials, chemical industry, electric power, metallurgy, coal coal, grain and other industries, suitable for horizontal or inclined transport of powder, granular and small materials, such as coal, ash, slag, cement, grain, material temperature is less than 200℃. The screw machine is not suitable for conveying perishable, viscous, easily caked materials. In the concrete mixing plant, the role of the screw conveyor has been the biggest embodiment.

Maintenance and management

Screw conveyor in the use of the process, must pay attention to the daily maintenance, so as to maximize the sand dryer with good cooperation, to ensure the production capacity and efficiency, but also to prolong the service life of the equipment.

(1) Lubricating oil shall be added to transmission parts such as bearing, gear and chain regularly.

(2) After the box feeding machine is stopped, the spiral blade shall be inspected for wear and repair welding in case of serious wear.

(3) The conveying quantity should not be overloaded, otherwise the material cannot be discharged, which will cause the spiral shaft bending and the box body swelling.

(4) When the conveying medium is of high deflection, attention should be paid to whether the expansion and contraction of the box body is free and not stuck, if there is a solution.

(5) In the operation of the conveyor, when the noise jarring, should be opened to check, troubleshoot.
