In the process of ceramsite production, the conveying of raw materials is an important part of the production process. Due to the high moisture content of ceramsite raw materials, traditional conveying equipment has certain limitations in terms of material adaptability and site location layout. Introduce a conveying equipment suitable for ceramsite raw materials - shaftless screw conveyor; because of its non-central shaft structure, the steel spiral body is directly connected with the transmission device, which can be made into a cantilever structure, especially suitable for the ceramsite rotary kiln, the material at the end of the kiln is fed into the kiln.
1. Product introduction:
The shaftless screw conveyor is an alternative to the shafted conveyor. Its screw body is a shaftless screw. It has the advantages of high working efficiency, simple maintenance, less pollution and low noise. Not only can it transport the light, soft, small, ribbon-like floating substances that old-fashioned equipment can't transport, but also can separate sand and water and squeeze dirt. Beautiful appearance and reasonable structure.
2. Product working principle:
The working principle is the same as that of the shaft screw conveyor, and the material is pushed forward by the rotation of the blades. The performance characteristics of the shaftless screw conveyor are: compared with the traditional shafted screw conveyor, the shaftless screw conveyor has the above outstanding advantages due to the design without a central shaft and the use of a certain flexible integral steel screw to push the material, good environmental performance. Compared with the shaft screw conveyor, the weight and cost will be reduced a lot.
3. Product performance characteristics:
Shaftless screw conveyors can convey materials that traditional shaft screw conveyors and belt conveyors cannot or are difficult to convey, such as granular and powdery materials, wet and pasty materials, semi-fluid and viscous materials, easy to entangle and easy to block materials, materials with special hygiene requirements.
1) Good environmental performance. The fully enclosed and easy-to-clean spiral surface can ensure that the conveyed material is not contaminated and will not leak the conveyed material.
2) The conveying capacity is large, and the conveying capacity is 1.5 times that of the shaft screw conveyor with the same diameter.
3) The torque is large, the energy consumption is low, and the discharge port is not blocked.
4) The conveying distance is long, and the conveying length of a single machine can reach 60~70m.
5) Compact structure, space saving, beautiful appearance, easy operation, economical and durable.
4. The structure of the product:
Shaftless screw conveyor is mainly composed of driving device, head assembly, casing, shaftless screw body, tank lining plate, feeding port, discharging port, cover (when necessary), base and so on.
Driving device: Cycloidal pinwheel reducer or shaft-mounted hard-tooth surface gear reducer is used. In the design, the driving device should be set at the end of the discharge port as much as possible, so that the screw body is in a tension state during operation.
The head is equipped with a thrust bearing, which can bear the axial force generated when conveying materials.
Chassis: The chassis is U-shaped or O-shaped, with a rain-proof cover on the upper part, and the material is stainless steel or carbon steel or FRP.
Shaftless Spiral: The material is stainless steel or carbon steel.
Tank liner: The material is wear-resistant plastic plate or rubber plate or cast stone plate, etc.
Inlet and outlet: There are two kinds of square and round. Generally, the form of inlet and outlet is determined by the user.
