Abstract

The invention discloses a control technology of a heavy punch unloader type small pulsed jet cloth filter. The control technology comprises the following steps: at the beginning, starting a fan and starting a timer to time, and determining an interval time of cleaning dust; when the timer is less than 60 seconds, re-determining the interval time of cleaning the dust; when the timer is less than 4 hours and more than 60 seconds, starting an online dust cleaning procedure, and starting electromagnetic pulse-jet valves sequentially to clean dust; when the timer is greater than 4 hours, starting an off-line dust cleaning procedure, stopping the fan, starting the electromagnetic pulse-jet valves sequentially to clean dust, ending dust cleaning, starting the fan, and resetting the timer. According to the control technology of the heavy punch unloader type small pulsed jet cloth filter, the off-line dust cleaning procedure is added, through a mode of stopping of the fan, the dust cleaning operation on a filter bag module is realized, the service life of a filter bag is prolonged and the dust collecting effect of the jet cloth filter is improved.

Description

technical field [0001] The invention relates to a pulse bag filter, in particular to a control process for a small pulse bag filter with a heavy hammer unloader. Background technique [0002] The dust removal control of the pulse bag filter adopts PLC microcomputer program control instrument, timing (automatic) and manual three control methods. Timing control: According to the set time, each room is cleaned in sequence every other cleaning cycle. Manual control: On the field operation cabinet, it can be manually controlled to automatically clean the dust in each room in turn, or it can be cleaned separately for each room. [0003] Heavy hammer unloader type small pulse bag filter is widely used in various production sites such as metallurgy, building materials, machinery, chemical industry, mining, etc. The dust on site seriously endangers human health. The dust collector adopts the pulse jet dust removal method, which has the advantages of good dust removal effect, high p...
