The cooling screw conveyor is a high-temperature resistant screw conveyor that transports high-temperature powder, small particles and other bulk materials in a closed tube body. The maximum temperature of the feed material can reach It has the lowest temperature reach and is a conveying equipment that integrates cooling and conveying.
High temperature resistant screw conveyors usually consist of three parts: the screw conveyor body, the in and out device, and the driving device. The screw machine body consists of three parts: the head section, the middle section and the tail section. The high-temperature-resistant screw conveyor is equipped with a water-cooling system. The materials are made of high-temperature resistant materials. The bearings are imported bearings. There is an external cooling water jacket outside the cylinder, and both ends of the rotating shaft are empty tubes. The cavity of the spiral plate is connected with the empty pipes at both ends of the rotating shaft. The cooling water flows from the empty pipe at the inlet end through the cavity of the spiral plate and then flows out from the empty pipe at the outlet end to form an internal cooling water channel. The material is cooled evenly during the conveying process, and the cooling effect is good. In addition, our company has developed a system where water does not circulate in the spiral and does not scale, thus reducing maintenance time and enhancing production efficiency.
Application fields
Building materials, metallurgy, chemical industry, mining, machinery manufacturing, coal, tobacco, grain, medicine and other industries.
Main features
The high temperature resistant screw conveyor is suitable for conveying cement clinker and slag at the bottom and top of the warehouse.
The high-temperature resistant screw conveyor can be fully enclosed to eliminate dust pollution, or it can be transported in an open manner.
The distance of a single conveyor can reach meters, and the soft connection of multiple machines can be extended as needed.
Advantages
Simple structure, easy debugging, few types of wearing parts, and easy maintenance.
It has large conveying capacity, good heat insulation effect, no need for cooling device and low power consumption.
It starts and stops quickly, runs smoothly, has good vibration isolation performance and low noise.
Easy to install, no special foundation or corner bolts required, easy to move.
Under normal circumstances, the screw conveyor
middle sections are arranged in order of length when leaving the factory. The longest middle section is close to the head section, and the middle sections of the same length are next to each other. If there are special requirements , then give the order when ordering. A thrust bearing is installed in the head section of the screw conveyor to bear the axial force, and a bearing is installed in the middle section and the tail section to support the screw shaft. In addition, a radial bearing that can move axially is installed in the tail section of the screw conveyor. Compensates for screw shaft length errors and adapts to temperature changes. There are two types of screw conveyor spiral surfaces: solid spiral (manufacturing method) and belt spiral (manufacturing method). The flange connection between each spiral shaft ensures the interchangeability of the connecting shaft and facilitates maintenance. The cover of the screw conveyor is a tile type and is clamped to the casing with cover buckles. If the sealing performance needs to be improved, the user can add waterproof canvas between the cover and the casing. There are four types of screw conveyor inlet and outlet devices: inlet, square outlet, push-type outlet, and rack-type outlet. The user can weld the opening on the machine body at the site of use.
