Description

Technical Field

[0001] The utility model relates to the technical field of deaerator cleaning, in particular to a deaerator inner wall scale cleaning mechanism. Background Art

[0002] A deaerator is a device used to remove oxygen from water. It usually consists of a bottom water tank, a deaerator, and a monitoring device. It can effectively prevent oxygen from causing corrosion and damage to metal equipment, thereby reducing the maintenance cost of metal equipment.

[0003] When the deaerator is in use, the oxygenated water is sent to the deaerator for deoxygenation through the bottom water tank, which contains water and provides circulation. Since the water stays in the bottom water tank for a long time, scale is often generated, which can easily have a certain impact on the use of the deaerator. The existing method for cleaning the scale on the inner wall of the deaerator is generally to add a descaling agent to the inside of the deaerator to soften the scale, and then clean the softened scale. In this process, since the volume of the bottom water tank in the deaerator is large, the bottom water tank needs to be filled with a mixture of descaling agent and water to ensure that the mixture is in full contact with the inner wall of the bottom water tank, which leads to a longer time for softening the scale, a low efficiency of cleaning the scale on the inner wall of the deaerator, and a waste of water resources.

[0030] The outer surface of the hollow rod 55 is provided with through holes at equal intervals, and air can be discharged through the through holes to inflate the airbag 59 .

[0031] When in use, close the exhaust valve 8, start the motor 41, and the output end of the motor 41 rotates forward to drive the reciprocating screw 42 to rotate, and then the reciprocating screw 42 rotates to drive the pressure plate 43 to move back and forth, so that the external airflow enters the interior of the hollow rod 55 through the shell 45 and the connecting pipe 46, and then is discharged through the through hole on the hollow rod 55, so that the airbag 59 expands and the internal space of the deaerator body 1 is separated.

[0036] Working principle: When in use, close the exhaust valve 8, start the motor 41, the output end of the motor 41 rotates forward to drive the reciprocating screw 42 to rotate, and then the reciprocating screw 42 rotates to drive the pressure plate 43 to move back and forth, so that the external airflow passes through the shell 45 and the connecting pipe 46 into the hollow rod 55, and then is discharged through the through hole on the hollow rod 55, so that the airbag 59 expands and the internal space of the deaerator body 1 is separated.

The output end of the motor 41 reverses to drive the reciprocating screw 42 to reverse, and then the reciprocating screw 42 reverses to drive the main gear 53 to reverse, thereby driving the one-way gear 52 to rotate, and then the one-way gear 52 rotates to drive the rotating shaft 51 to rotate, and then the pulley 1 54 rotates, and then the pulley 2 56 rotates through the rotation of the pulley 1 54, and then the hollow rod 55 rotates, and then the cleaning plate 58 rotates through the rotation of the hollow rod 55 to clean the scale on the inner wall of the deaerator body 1 after softening.
