Description
Technical Field
The invention relates to the field of dust collectors, in particular to an intelligent arch breaking control method for an ash hopper of a dust collector.
Background
The bag type dust collector has the working principle of filtering-deashing-filtering, wherein the filtering is to realize gas-solid separation through a filter bag and remove dust particles in dust-containing gas, the deashing is to clear away dust accumulated on the filter bag through pulse compressed air, and the dust falls into a dust hopper and is discharged from the dust hopper. When the dust collected by the dust hopper of the dust remover has large moisture and poor liquidity, the phenomena of wall sticking, caking and shed arching of dust can be caused. Especially when the dust collected by the ash bucket is pulverized coal, the pulverized coal can be spontaneously combusted and even explode due to the fact that the long-term dust is stuck to the wall, agglomerated and arched in a shed. Therefore, a rapping motor is added on the dust hopper of the dust remover to solve the problems of wall sticking, caking and shed arching of dust. However, as the ash bucket is a welded part of a steel plate, the long-term rapping can crack welding seams and even lead to the ash bucket being scattered.
Disclosure of Invention
The invention aims to solve the technical problem of providing an intelligent arch breaking control method for an ash bucket of a dust collector, which can intelligently control the start and stop of a rapping motor through the acquisition signal of a material level meter and avoid the problem of quick damage of the ash bucket caused by rapping the ash bucket for a long time.
The technical scheme of the invention is as follows:
an intelligent arch breaking control method for an ash hopper of a dust remover specifically comprises the following steps:
(1) firstly, fixing a feeding level indicator and a discharging level indicator on the inner wall of an ash bucket of the dust remover, wherein the feeding level indicator is adjacent to the top end of the ash bucket, the discharging level indicator is adjacent to the bottom end of the ash bucket, a rapping motor is fixed on the ash bucket of the dust remover, and the feeding level indicator, the discharging level indicator and the vibrating motor are all connected with a controller;
(2) when the blanking level indicator detects ash materials and the loading level indicator does not detect the ash materials, the controller controls the rapping motor to stop rapping, and blanking is naturally carried out;
(3) when the loading level indicator and the unloading level indicator detect ash materials, the controller controls the rapping motor to start rapping so as to carry out quick unloading;
(4) when the material loading level meter detects ash materials and the material unloading level meter does not detect the ash materials, the phenomena of wall sticking, caking and shed arching of the ash materials on the inner wall of the ash bucket of the dust remover are shown, and the controller controls the rapping motor to start rapping so as to carry out rapping and blanking.
When the material loading level indicator detects ash materials, the controller starts the vibrating motor and sends alarm prompt information to the display screen for alarm prompt.
When the material loading level indicator detects ash materials and the material unloading level indicator does not detect ash materials, the controller sends alarm prompt information to the display screen to prompt workers of the phenomenon of shed arching.
When the material loading level indicator and the material unloading level indicator detect ash materials, the controller sends alarm prompt information to the display screen to prompt workers of the ash gambling phenomenon.
The dust remover ash bucket be a plurality of, last charge level indicator, the unloading charge level indicator on a plurality of dust remover ash buckets, vibrating motor all are connected with the controller, the controller is according to the collection signal output control signal who goes up the charge level indicator and descend the charge level indicator for the motor that shakes that corresponds, realizes centralized control.
The invention has the advantages that:
the controller of the invention judges the state of the ash in the ash bucket according to the signals collected by different level gauges, and then controls the start and stop of the rapping motor according to different states, thereby avoiding the problem of quick damage of the ash bucket caused by rapping the ash bucket for a long time and ensuring that the phenomena of ash piling, wall sticking, caking and shed arching can not be generated in the ash bucket.
