Description

Sack cleaner

Technical field

The invention belongs to cleaner, particularly a kind of sack cleaner.

Background technology

Along with industrial activity increases rapidly, smoke contamination is on the rise, industry smoke-dust, the particles that the diameter that the pollutions such as construction fugitive dust cause is less than more than 2.5 microns and 2.5 microns become the main pollutant of present stage China, haze weather is affecting people's life, haze weather has caused continuous many traffic accidents on a large scale, in the various big hospital of city, Respiratory Medicine, the numbers of seeing and treating patients such as the anaphylactogen test section several times that also rise violently, therefore except steel-making, the large-scale pollution project such as generating need to administer, some small-sized iron and steel kilns, non-ferrous metal metallurgy, specialty metal is smelted, the treating flour dust of transfer station etc. is extremely urgent.

And these need the enterprise for the treatment of flour dust to be mostly the small enterprise that some are small, technology falls behind relatively, conventionally the cost of selected pulse bag type dust collector is high, it is a lot of that Maintenance Difficulty increases the difficulty of environment protection treating, inward flow filtration-type deduster is the one of sack cleaner, be widely used in early days industrial dedusting industry, its have advantages of with low cost, operation is simple, good dedusting effect., there is following shortcoming in the purge mode of mechanical vibrator: (1) mechanical rapping cleaning dust, make cloth bag bent, folding repeatedly, and cause the cloth bag life-span to shorten, spoilage is high; (2) mechanical rapping cleaning dust belongs to weak energy deashing, cannot be applied to the dedusting industry that dust size is less, operating mode is complicated; (3) bent, the folding repeatedly of cloth bag, requires the space between cloth bag to want large, therefore cause the Bag filter area in unit volume too little.

Summary of the invention

The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of compact conformation, volume little, good dedusting effect, the sack cleaner of long service life.

The technical scheme that technical solution problem of the present invention adopts is: sack cleaner comprises frame, ash bucket, middle casing, air inlet, air outlet, driving mechanism, be characterized in being fixedly equipped with middle casing above frame, on fixing deashing mechanism chassis, the top of middle casing, on deashing mechanism chassis, deashing mechanism is housed, in the middle casing of below, deashing mechanism chassis, be divided into multiple air-purifying chambers, the top of air-purifying chamber is provided with air outlet, on the termination, left side above deashing mechanism chassis, fill driving mechanism, on deashing mechanism, establish several vibrating mechanisms that formed by vertical shaft upper bracket and vertical shaft lower carriage, on deashing mechanism chassis, fill vertical shaft lower carriage with vertical shaft undersetting, above vertical shaft lower carriage, fill vertical shaft upper bracket with fastening bolt nut, the protruding dish of center dress curve in vertical shaft upper bracket and vertical shaft lower carriage, filter element framework in connecting with upper hanging rod on deashing mechanism between vibrating mechanism in casing, below filter element framework, connect several independently cloth bags with cloth bag chaining, in the middle of filter element framework, be provided with frame center axle, both sides at frame center axle are provided with frame supported, frame center axle lower end connects lower peg, below filter element framework, be provided with the sealed outer ring of sealing inner ring, below connecting cloth bag, be provided with card, on card all apart from being provided with several cards hole, each independently cloth bag lower end is all fixed in card hole with spring piston ring, the frame that connects card below is provided with ash bucket, in ash bucket center with under peg spacing pallet is housed, below spacing pallet, chassis is housed, above chassis He in spacing pallet, high energy spring is housed, on excircle above spacing pallet, symmetry is connected on the inwall of ash bucket with spring support.

The invention has the beneficial effects as follows: sack cleaner has been avoided mechanical rapping cleaning dust, make cloth bag repeatedly tortuous, cause the cloth bag life-span to shorten, the shortcoming that spoilage is high, the kinetic energy that simultaneously high-speed motion produces is more thorough than mechanical ash removing, deashing dirt effective, energy-conserving and environment-protective.
