Embodiment 1

[0026] Motor I6 is installed on the base 4, and motor I is connected to platform 3 through eccentric wheel rocker arm 9, and platform 3 is provided with motor II7 and counterweight 5, and motor II is connected to bottle body 2 through chain, and the top of platform 3 is provided with for fixing A fixed frame of the bottle body 2; the fixed frame is composed of a chuck 1 and a tail top 8.

[0027] Taking the small-bore cylinder as an example, the derusting method of the present invention comprises the following steps:

[0028] Fill the bottle to be processed with high-hardness abrasives and grinding liquid, and fix the bottle body with the tail top and the chuck; when the motor II is working, the bottle body is driven to rotate by the chain; the abrasive in the bottle body rotates under gravity and the bottle body The relative movement is generated under the action of the motor, so as to achieve the effect of cutting the surface; when the motor I rotates, the eccentric rocker a...

Embodiment 2

[0034] The concentration of described sodium nitrite solution is 15g / L, and the concentration of sodium carbonate solution is 2g / L, and other structures and methods are with embodiment 1.

Abstract

The present invention relates to a kind of liner light decoration derusting equipment and derusting method for derusting the inner surface of the bottle body of aerospace gas circuit system. There is a motor II on the top, and the motor II is connected to the bottle body through the transmission device II, and a fixing frame for fixing the bottle body is arranged above the platform. The invention adopts the derusting technology of light decoration, and achieves the effect of derusting by grinding the inner surface of the bottle with abrasive materials, which not only effectively removes the rust in the cavity of the inner surface of the bottle, but also avoids the hydrogen embrittlement problem caused by pickling, and The local rust cleaning problem existing in sand blasting is not in place, and it has a strong promotional effect on the rust removal of the inner surface of the bottle.

Description

technical field [0001] The invention relates to a device and a method for removing rust on the inner surface of equipment, in particular to an inner tank light decoration rust removal device and a rust removal method for removing rust on the inner surface of a bottle of an aerospace gas path system. Background technique [0002] At present, the rust removal of the inner surface of the gas cylinder in the aerospace gas system has always been a technical problem in the field, especially the rust removal of the inner surface of the irregularly shaped bottle is not easy to operate. The rust removal methods in the prior art are mainly sandblasting and pickling, but the above methods have their limitations. Sandblasting the inner tank of the bottle is prone to blind spots, resulting in the problem that the rust cannot be removed. Pickling is forbidden for strong steel. Restricted technology, prohibited in aviation and aerospace enterprises. [0003] Rolling is the process of putt...
