Air tightness detection device for enamel assembled tank

Abstract

The invention relates to the technical field of enamel production equipment, and discloses an air tightness detection device for an enamel assembled tank. The device comprises a water tank, an assembled tank and a booster pump, wherein guide grooves are formed in the two sides of an inner cavity of the water tank, balance weight sliding blocks are movably installed in the guide grooves, one side of each balance weight sliding block is fixedly connected with a rotating box, a movable shaft is movably connected into the rotating box, and a fixing frame is fixedly connected to the position, located on the outer side of the rotating box, of one end of the movable shaft. Through the arrangement of the rotating box and the connecting piece, the assembled tank rotates in water, the surface of the assembled tank can receive pressure of water of different depths, it is ensured that the pressure bearing degree of all the positions of the assembled tank is kept within a certain range, the detection quality is improved, meanwhile, the pressure borne by all the positions of the assembled tank is constantly changed within a certain period of time, the pressure effect of water on the surface of the assembled tank is increased, the inspection strength of the assembled tank is increased, and the quality of the assembled tank product is improved.

Description

technical field [0001] The invention relates to the technical field of enamel production equipment, in particular to an airtightness detection device for an enamel assembled tank. Background technique [0002] Enamel, also known as enamel, is a composite material that melts and condenses inorganic glassy materials on the base metal and combines them firmly with the metal. As one of the most important parts, the enamel liner is durable under pressure and corrosion , anti-absorption and other characteristics, all kinds of ions can not penetrate the surface of the enamel liner, which can effectively ensure that the water quality is not polluted, and it has been widely used in various water heater fields. At present, when the enamel liner is fired, in order to test the air tightness and structural strength, the enamel liner will be pressed into the water by a mechanical arm to maintain the pressure. After a period of time, it will be observed whether there are defects on the sur...

AI Technical Summary

Problems solved by technology

[0003] When testing, the enamel liner is sealed, and then put into the water. The mechanical arm above it presses it into the water to a certain depth. However, due to the large volume of the enamel assembled tank, the depths of the top and bottom are different. Therefore, the pressure of the water is different, which leads to the inability to carry out a uniform pressure-holding test on the inner tank during the test. As a result, due to the small pressure on the upper side, the detection is not in place, which affects the quality of the test. The buoyancy of the robot is relatively large, and a large force is required to press it into the water, and the long-term pressure maintenance will place a large burden on the mechanical arm.
