Description
Technical Field
The invention belongs to the technical field of dehydrator roller, and particularly relates to a dehydrator roller welding structure suitable for the diameter of more than 160 mm.
Background
The sludge is a necessary product after sewage treatment in sewage treatment plants and sewage stations, and after the sludge which is not treated well enters the environment, secondary pollution is directly brought to water and atmosphere, and serious threat is formed to ecological environment and human activities. Therefore, the sludge is very careful in handling. The sludge is mainly treated by a sludge dewatering process. The hydroextractor on the existing market mainly divide into: centrifugal dehydrator, belt dehydrator and spiral ring and cartridge type dehydrator. We now discuss a belt extractor.
Currently, various problems exist with the belt dryers on the market. From the principle of the belt dewaterer, the pressure of the belt dewaterer on the press roll must be increased to reduce the water content of the dewatered sludge, so that a problem must be brought, namely the stress condition of the shaft head of the shaft roll becomes very poor, and the shaft head of the shaft roll is finally fractured due to overlarge pressure.
The welding form of the shaft heads of the shaft rollers of the belt type dewaterer on the market at present is shown in figure 5; the structure is that the shaft head 2-1 is arranged in the shaft barrel 1, a groove with a certain distance is reserved at the end part of the shaft head, and the groove is welded fully after the two parts are installed in place. This structure has a great problem. When the beam barrel receives great external force, the welding position can be broken, so that the dehydrator can not work normally, and the shutdown maintenance is needed. Therefore, the working efficiency of the belt type dehydrator is greatly reduced, and the filter cloth is damaged under the more serious condition, so that the greater economic loss is caused. In addition, repairing the roll of this construction can only be accomplished by repair welding, which does not improve the shaft breakage. After the shaft head welding seam of the shaft roller is broken, repair welding is required. However, the working condition of the dehydrator is severe, and the shaft roller is seriously corroded, so that great difficulty is brought to repairing of a fractured welding seam, the repairing time is prolonged, and the working efficiency of the dehydrator is seriously influenced.
For the dehydrator shaft roller with the diameter smaller than 160mm, the following technical scheme is adopted for welding: firstly, the shaft head and the shaft barrel in the figure 3 are processed according to the design size, and the shaft head 2-1 and the shaft barrel 1 are assembled according to the position shown in the figure. The assembly at this time should use hot assembly. The design position is packed into with the spindle nose before the assembly promptly, utilizes the object shrinkage principle of rising with heat, and the aperture of heating back spindle nose tip can the grow, cools off to the room temperature after the assembly, and the spindle nose can produce interference fit with the spindle nose this moment, makes the spindle nose hole die and lock the spindle nose rear end tightly. And then, assembling the assembled shaft roller with the pin holes according to the designed size on site, wherein the positions of the pin holes are symmetrical relative to the axis. And (3) filling the pin shafts 4 into the punched pin holes, enabling the upper ends of the pin shafts to be located in the middle of the wall of the shaft barrel, firmly welding all the pin shafts and the shaft barrel by plug welding, and polishing and removing redundant welding seams. And finally, performing full-circle welding on the shaft head and a groove reserved at the outer end of the shaft barrel, and welding and forming the whole shaft roller. The stress condition of the shaft head of the shaft roller becomes better, but the shaft head is not suitable for the condition of overlarge pressure, and practical application proves that the structure is often applied to the shaft roller of the dehydrator with the diameter larger than 160mm, and the overlarge pressure finally causes the problem of breakage of the shaft head of the shaft roller.
