Abstract
The present invention discloses a kind of small-sized pulsed jet cloth filter control technique of weight discharger formula, and the control technique comprises the steps：During beginning, blower fan starts, and timer starts timing, thus judges deashing interval time；When timer is less than 60 seconds, deashing interval time is rejudged；When timer is small less than 4 and more than 60 seconds, online ash removal program starts, electromagnetic pulse blowing valve sequential start deashing；When timer is small more than 4, off-line ash-clearing program starts, and stops blower fan, and electromagnetic pulse blowing valve sequential start deashing, deashing terminates, and starts blower fan, and timer is reset.Ratio of the invention adds off-line ash-clearing program, by way of blowing-out machine, realizes the deashing operation on filter bay assembly, improves life of bag filter, improves deduster dust collection effect.
Description
Technical field
The present invention relates to a kind of pulsed jet cloth filter, specifically a kind of small-sized pulsed jet cloth filter of weight discharger formula
Control technique.
Background technology
Pulsed jet cloth filter dust-removing control uses the micro computer programmed instrument of PLC, timing (automatic), manual three kinds of controlling parties
Formula.Timing controlled：By setting time, every a cleaning cycle, deashing one time successively of each room.Control manually：Operate at the scene
Manually controllable each room automatic ash removing successively one time on cabinet, also can be to the independent deashing in each room.
It is each that the small-sized pulsed sack cleaner of weight discharger formula is widely used in metallurgy, building materials, machinery, chemical industry, mine etc.
Production scene is planted, its live dust seriously endangers health.Deduster uses the purge mode of pulse jet, with deashing effect
Really good, purification efficiency is high, processing air quantity big, life-span of the filter bag length, maintenance load are small, it is safe and reliable to operation the advantages of.Weight is unloaded
Glassware has simple in construction a, advantage such as maintenance is small, but deduster, when continuously running, because of the suction of blower fan, weight discharger is not
Easily action, a large amount of dusts are suspended in ash bucket, influence efficiency of dust collection and life of bag filter.
The content of the invention
It is an object of the invention to provide a kind of small-sized sack cleaner control technique of weight discharger formula pulse, to solve
The problem of dust that the existing small-sized pulsed jet cloth filter of weight discharger formula is present is suspended in ash bucket.
The purpose of the present invention can be achieved through the following technical solutions：
The small-sized pulsed jet cloth filter control technique of weight discharger formula, it is characterised in that the control technique includes following
Step：
During beginning, blower fan starts, and timer starts timing, thus judges deashing interval time；
When timer is less than 60 seconds, deashing interval time is rejudged；
When timer is small less than 4 and more than 60 seconds, online ash removal program starts, and electromagnetic pulse blowing valve sequential start is clear
Ash；
When timer is small more than 4, off-line ash-clearing program starts, and stops blower fan, and electromagnetic pulse blowing valve sequential start is clear
Ash, deashing terminates, and starts blower fan, and timer is reset.
The dust that the electromagnetic pulse blowing valve is shaken off on filter bay assembly makes it fall into ash bucket, then is unloaded by the weight of bottom
Glassware is drained on conveyer belt.
The electromagnetic pulse blowing valve is arranged on filter bay assembly；The filter bay assembly is arranged on box house；The case
Blower fan is installed at the top of body.
The ash bucket is arranged on bottom half, and ash bucket side wall is provided with weight discharger provided with the mouth that gathers dust, ash bucket bottom,
The upright contraposition place of putting is provided with conveyer belt under weight discharger.
Dusty gas enters ash bucket by the mouth that gathers dust, and ash bucket is fallen directly into after big dust particle separation, remaining dust with
Air-flow enters casing, and the clean gas after filtering is discharged through filter bay assembly via blower fan.
Beneficial effects of the present invention：The present invention adds off-line ash-clearing program than common small-sized pulse dust collector, passes through
The mode of blowing-out machine, the dust on filter bay assembly is shaken off using electromagnetic pulse blowing valve makes it fall into ash bucket, then passes through bottom
Weight discharger is drained on conveyer belt, realizes the deashing operation on filter bay assembly；The dust of accumulation is allowed to be opened by conducting oneself with dignity simultaneously
Weight discharger, completes ash discharge, then carries out carrying out off-line ash-clearing to filter bag, reduces resistance of the filter bag, reduces fan energy consumption, improves filter
Bag service life, improves deduster dust collection effect.
