CS252857B1 - Ancillary construction reducing corrosion cracking of the ammonium drum - Google Patents

Abstract

The condition for cracking in nitrogen is the existence of its main 'liquid environment and pressure. The susceptibility to cracking can be reduced by using quenched and microalloyed steels, or high-alloyed materials. In special carbon steels, the desired effect is not always achieved, and stress from loading and residual stresses mainly after assembly welds cause a smaller, but always existing risk of cracking. The production of pipes from high-alloyed materials is very uneconomical. The proposed design reduces stress by creating a stronger supporting structure and completely eliminates one of the conditions for cracking, i.e. stress.

Description

The invention relates to an auxiliary device which reduces the total corrosion protection of the porous material in a drying, cooling and granule drying plant, or solutions of ammonium nitrate. Ammonium solution and granule solutions and granules are manufactured because of the reduction of the overexploitation price from the lozenges of the mica-olegated-ol olefin. In particular, they are large-sized, such as granules, desiccants, and buffers. These drums with a diameter of up to 3 m, lengths up to 25 m, have a weight of up to 100 t-oins. It is possible to add to this weight the weight of the continuous content, which is to be applied by sticking the material, to the weight of the other 100 tons.

The shell is a substantially thin-walled support beam in the locations of the running pulleys. From flexural bending to high-pressure alternating pressure and tension-tension stresses. This whole is rotated by the cogwheels, which, in turn, introduces other sicriuite materials which increase the irregularity of the run-up and the braking. The resulting stresses in the walls during their oversizing reach high. P, re-emergence of the so-called iprascariae in nitric amine, ie from the microcapsules leading mainly to the trans-crystals to the crack of the wall, two facts are needed, namely tension and soil-o -benie -dusičnano-v. N-aviac to -destruk! it occurs in the mass, te-d-a is normally visually unobservable. Not all types of steel are equally susceptible to cracking, but cracks increase each time. Therefore, the formation conditions need to be eliminated for cracking. The manufacturing technology technician is essentially non-changeable and non-removable. The second option is j-e-in reducing tension. Reducing the stress of the wall ridge is uneconomical and inefficient. The greater the gross weight, the greater the weight, and the poor the weight.

OBJECTS An auxiliary design for reducing the corrosion cracking of the drying drum of ammonium, characterized in that it is formed by a translucent icoin (3) fixed at the site having a structure to wash all tension. The structure of the figure is formed by a p-ri-hexadecimal conjugate 3, which is fixed at the support site 2 (essentially the normal paths of the drum 1) by means of an annular ring 5. and resilient sleeves 4 to the drum 1, to reduce or completely remove the tension in the walls of the drum 1. According to the invention, all the tension is transmitted through a separate support structure. In this way, it will be appreciated that the part of the device in which the transfer of the material to the material used and the structures does not come into contact with the medium. On the other hand, the actual b-ubon, in which, for example, the lithium is granulated, dried, and cooled, it does not have any high stresses in addition to the residual loads. In this way, the food is always eliminated from the causes of the pigs, and it is ensured by them and their distances. The solution according to the invention thus eliminates one of the conditions for the formation of dust, without the need for expensive high-alloying materials. By using a stand-alone cage, the cross-section of the drum itself is reduced, thereby reducing its weight, so that the weight of the stiffener and the cage only from a part of the height is reduced. total weight of the device. A further advantage is the fact that when the drum is cracked for a long time, it can be gradually replaced in the individual flaps. The repair of the prior art may be essentially a substantial replacement. In one particular application of the present invention to the drying drum, the cracks detected are rescued into a new lock of the new drum. The tumbling of the drum with hoop-and-thrust and torsion springs in the coil-oh-twist hammers hurts these flanges in the longitudinal axis of the drum. These flanges dropped in position, transmitting tensile and -pressure tension to the suppressor, stopping another 'ras-t-crack. As a further use of the present invention, it is possible to impart application to all nitrous man-made fertilizers and also to agitate them. Thus, the use of high molecular weight materials for a very small amount is avoided.
