Description

Online cleaning device of ash bucket of dry process dust remover

Technical Field

The utility model relates to the technical field of environmental protection dust removal, in particular to an online cleaning device for an ash bucket of a dry-method dust remover.

Background

The dust remover is an essential environmental protection device in the environmental treatment process, and the dust remover is generally divided into a dry dust remover and a wet dust remover, and is selected according to different dust removing media. Wherein, the dust collected by the dry dust collector (such as an electrostatic precipitator, a cloth bag dust collector and the like) is usually discharged by an ash bucket and then conveyed by adopting a pneumatic or suction and discharge vehicle mode.

The ash bucket commonly used in the dry dust remover is an inverted triangle cone bucket with a rectangular cross section, and the change of the cone is beneficial to collecting and discharging dust. However, due to different properties of the dust, the phenomenon of dust accumulation and hardening on the inner wall of the dust hopper is easy to occur after long-time accumulation, especially the phenomenon that the high-temperature dust remover and the dust with the burning agent or the substances with high viscosity are extremely easy to adhere to the inner wall of the dust hopper and continuously and repeatedly adhere to the subsequent dust, and a thick layer of viscous caking is formed on the inner wall of the dust hopper for a long time. The adhesion between the adhesive agglomeration and the inner wall of the ash bucket is strong, and the ash bucket or the pipeline can not be blocked after a long time by using a pneumatic conveying or suction and discharge vehicle, so that the normal operation of the dust remover is affected. Especially, if the inner wall of the ash bucket is hardened and agglomerated, the ash bucket is difficult to process, and long-time maintenance is needed, so that the yield is affected, and a large amount of manpower and material resources are wasted.

At present, dust is generally vibrated and fallen by electric vibration or manual vibration aiming at dust dipping of the inner wall of an ash bucket of the dry-method dust remover. However, the cleaning effect of vibration is poor for the dust deposit with high viscosity and high temperature, and the condition of the accumulation of the sticky blocks cannot be changed.

The working process of the utility model is as follows:

The winding motor drives the roller to rotate, and the steel wire rope pulls the fixed brush cylinder to enable the brush cylinder to ascend. In the upward process of the fixed brush cylinder, the steel wire brush at the bottom of the fixed brush cylinder contacts the inner wall surface of the ash bucket to clean; meanwhile, the travelling wheels synchronously travel along the sliding rail, the movable brush cylinder is pulled to gradually extend outwards, and the steel wire bundles of the extending part of the movable brush cylinder are ejected out under the action of the second spring and contact with the inner wall of the ash bucket to clean. When the fixed brush cylinder reaches the top of the ash bucket, the magnetic block on the fixed brush cylinder triggers the magnetic induction switch at the upper end of the ash bucket, and after the trigger signal is transmitted to the CPU, the CPU controls the winch motor to rotate reversely, and the steel wire rope pulls the fixed brush cylinder to move downwards.

During the descending process of the fixed brush cylinder, the movable brush cylinder gradually retracts inwards, and at the moment, the first spring is compressed. In the process of transversely moving the movable brush cylinder, the steel wire bundle is limited by the fixed brush cylinder, and the second spring is compressed to be retracted into the chute. When the fixed brush cylinder reaches the bottom of the ash bucket, the movable brush cylinder is completely retracted into the fixed brush cylinder; at this time, the magnetic block on the fixed brush cylinder triggers the magnetic induction switch at the lower end of the ash bucket, and after the trigger signal is transmitted to the CPU, the CPU controls the winding motor to reversely rotate again, and the steel wire rope pulls the fixed brush cylinder to ascend. Along with forward and reverse rotation of the winding motor, the fixed brush cylinder and the movable brush cylinder reciprocate up and down to remove an adhesive layer, a sticky block and the like on the inner wall of the ash bucket, so that the inner wall of the ash bucket is cleaned on line in real time.
