Description

Technical Field

[0001] The utility model relates to the technical field of transportation, in particular to a mobile motor reverse transportation device used in a film evaporator. Background Art

[0002] In the oil refining, chemical and other industrial fields, the operation of large-scale equipment areas is often accompanied by the generation of high-temperature media. The effective cooling of these media is crucial to ensure the continuity and safety of the production process. One of the traditional cooling methods is through an air cooling platform, in which the motor drives the fan blades to rotate through a belt to form an upward guide wind, thereby air-cooling the process tube bundle. This air cooling method can meet the basic cooling needs in most cases, but in extremely hot summers or under high-load operating conditions, its cooling effect is often unsatisfactory, and it is difficult to achieve the temperature indicators required by the process, which has an adverse effect on production efficiency and product quality.

[0003] In order to overcome the limitations of simple air cooling, the industry introduced membrane evaporators as auxiliary cooling systems. The membrane evaporator adopts a unique house-shaped design, which cleverly wraps two air coolers inside it to form a compact and efficient cooling unit. Its four walls are carefully designed as diversion types. The cooling water is transported to the upper side of the wall through the water pump circulation system, and then the cooling water naturally flows down along the diversion wall to the water pipe box below. In this process, the cooling water and the air have sufficient heat exchange, which effectively reduces the temperature of the surrounding environment. At the same time, combined with the dual effects of the closed water wall and air cooling, it provides a more significant cooling effect for the medium tube bundle, significantly improving the overall cooling performance.

[0004] However, although the film evaporator combined with air cooling has achieved significant advantages in cooling effect, its closed design has brought challenges to subsequent maintenance work. The main motor and fan pulley of the air-cooled fan are important objects of daily maintenance, and their maintenance and replacement usually require a large operating space. Traditionally, the industry will set up a special maintenance platform next to the air-cooling platform. The platform relies on an external power supply and realizes the lifting function through the forward and reverse drive hydraulic device of the built-in motor to facilitate the disassembly of the main motor and fan pulley. However, this type of maintenance platform is bulky, complicated to operate, and has high space requirements. It is particularly unsuitable when facing a closed film evaporator.

[0005] Especially when the main motor of the air-cooling fan fails seriously, it needs to be transported outside for professional maintenance. However, there is currently no effective solution for the reverse operation of the main motor inside the closed film evaporator. Utility Model Content
