Explosion proof tubular screw conveyor

Explosion proof tubular screw conveyors are not suitable for conveying materials that are prone to deterioration, high viscosity, and easy agglomeration, because these materials will adhere to the screw during transportation and rotate without moving forward or form material blockages at the suspension bearings, which will prevent the screw machine from working properly. The explosion-proof tube screw conveyor has five specifications with screw diameters ranging from 200 millimeters to 500 millimeters, and lengths ranging from 4 meters to 70 meters, with intervals of 0.5 meters. When selecting, the standard nominal length should be met, and any special requirements can be separately stated in the optional section.
The main points of explosion-proof tubular screw conveyor are:
1. High load-bearing capacity.
2. Strong adaptability, easy installation and maintenance, and long service life.
3. The whole machine has a small volume, high speed, and ensures fast and uniform conveying.
4. The discharge end is equipped with a cleaning device, which has low overall noise, strong adaptability, and flexible layout of the inlet and outlet positions.
5. Good sealing performance, the shell is made of seamless steel pipe, and the ends are connected to each other with flanges to form a whole, with good rigidity.
Explosion proof tubular screw conveyor uses a rotating screw to move the conveyed material along a fixed casing for conveying work. The head and tail bearings are moved outside the casing, and the suspension bearings are equipped with dust-proof sealing devices using sliding bearings. The bearing shells are generally made of powder metallurgy, and the conveying cement uses felt bearing shells. The suspension shaft and screw shaft are connected by sliding blocks. It has explosion-proof properties.
Installation and adjustment of explosion-proof tubular screw conveyor:
1. The centerline of the material trough should maintain good coaxiality with the spiral shaft.
2. The connection between each section of the material trough should be tight and there should be no misalignment. Gaskets can be added between sections and between the top cover and the trough to ensure the sealing of the trough, and the length error of the trough can also be adjusted.
3. The gap between the inner wall of the hopper and the surrounding area of the spiral body should be equal.
4. The drive device shaft and the screw shaft should maintain good coaxiality. When adjusting, the height of the driving device can be adjusted with the help of shims.
5. After the installation of the spiral body, it should undergo a static balance test.
6. The intermediate suspension bearing should properly support the connecting shaft to prevent radial deformation of the helical shaft. Installation can be achieved by adjusting the shims between the bearing shells to meet the requirements.
After the installation of the whole machine is completed, check whether there are any debris inside the machine and whether sufficient lubricating oil is added to each lubrication point.
During the no-load test, the bearings must not leak oil and the temperature rise of the bearings should not exceed 20 ℃. During load testing, the temperature rise of the bearing shall not exceed 30 ℃.
