Abstract

The utility model relates to a bag duster, the pneumatic vibrator of the bag duster with pneumatic vibrator is arranged on the upper part of the punching bag frame in a filter chamber or is arranged on the pattern chain of the lower part of the filter bag, or the pattern chains of the upper part of the punching bag frame and the lower part of the filter bag are simultaneously provided with a pneumatic vibrator. The utility model is formed by an upper and a lower box bodies which are combined together; the wind gets into the utility model from an air inlet on upper part of the ash hopper of the lower box body and gets into the filter bag through the hole of the pattern chain, and gas filtered by the filter bag gets into the upper box body and is expelled from an air outlet through a blower fan. The utility model has the advantages of simple structure, low energy consumption, high dust removing effect, small ground occupation, small resistance force, high vibration frequency and good ash removal effect.

Description

Bag duster with pneumatic vibrator

The utility model relates to a kind of exhaust dust device with bag.

The sack cleaner of Shi Yonging has pulse bag type dust collector in the past, machinery rotation blowback sack cleaner or the like.Exist defectives such as device structure complexity, consumable accessory is many, cost is high, maintenance cost is big, make troubles to the user.

By international online retrieval, retrieved the documents and materials of DILOG world patents index and U.S. engineering index, all do not see this pneumatic rapping sack cleaner.

The purpose of this utility model provides a kind of novel pneumatic rapping sack cleaner, to satisfy user's needs.

This pneumatic rapping sack cleaner is made up of air shaker, filter chamber, ash bucket.Air shaker is installed on the card of the top of the Pig framework in the filter chamber or filter bag bottom, or on the card of the top of Pig framework and filter bag bottom air shaker is installed simultaneously.(as Fig. 1), what have both at home and abroad utilizes pneumatic roll-type vibrator in the vibration of casting sandbox and the anti-arching of feed bin and the vibration that sandbox is unpacked.Be used for similar this deduster beyond example.The utility model is to use the vibration cleaning device of the roll-type vibrator of compressed air-driven as it, sack cleaner adopts the unit combination form, each unit is made up of 36 inward flow filtration-type filter bags, at deduster pure qi (oxygen) casing internal upper part, hang a vibration frame with regulating spring highly by screw rod, article 36, filter bag is hung under the framework, vibrator is fixed on frame center, with sebific duct and the outer compressed air gas source UNICOM of deduster, start the compressed air valve, pneumatic roll-type vibrator produces dither, frequency is more than the 80Hz, and Pig framework and filter bag produce vibration together, (pneumatic roll-type vibrator is seen Fig. 2), the card base of the bottom of filter bag and deduster is tight with the metal clip hoop clip, and this form is the top vibration.Around card, connect with rubber slab with housing, with spring card is hung on the housing, use bolting one vibrator at the card center, with sebific duct and the outer source of the gas UNICOM of deduster housing, open deduster valve vibration device and vibrate together with card and filter bag, this is the bottom vibration mode, also a vibrator can be installed respectively on the card of Pig framework upper and filter bag bottom, two vibrators vibrate simultaneously, and this is the third vibration mode.Structure such as Fig. 1 of this pneumatic rapping sack cleaner provide, by last, following two box body combinations form, by lower box ash bucket top air inlet air intake, enter filter bag by the card hole, gas after filter bag filters enters in the upper box is discharged through blower fan by exhaust outlet, after this deduster quits work, the deashing in each unit, or the not blowing-out machine in turn deashing of a unit, a unit in the course of the work, during every unit deashing, start vibrator and close this unit air outlet valve simultaneously and carry out vibration cleaning, the vibrator gas of discharging also can play the effect to the filter bag blowback simultaneously.Open vibrator and closing unit air outlet and adopt linkage, this pneumatic roll-type vibrator vibration frequency height, vibration acceleration is big, and ash-removal effect is good, at deduster inlet dust concentration 1g/m ³Under the situation,

Shift's deashing once gets final product, and continuous operation subdivision deashing adopts timing controller and two kinds of forms of differential pressure controller.The dust that falls clearly falls within the ash bucket and is discharged by ash-valve.

The utility model also has simple in structure, the vibration frequency height, and ash-removal effect is good, and the deashing energy consumption is low, and device structure resistance, running resistance are low, efficiency of dust collection height, characteristics such as floor space is little.

Accompanying drawing 1 is the utility model structural representation, and 1 is air shaker among the figure, and 2 is the filter chamber, and 3 is ash bucket, and 4 is the Pig framework, and 5 is card.

Accompanying drawing 2 is the air shaker schematic diagram.

Embodiment

Pneumatic rapping sack cleaner adopts the unit combination form, and filter chamber, every unit portion size is 1740 * 1740 * 2500～6000mm, the long 2000～5500mm of filter bag, and bag footpath φ 200mm, top is thin slightly, and is tapered slightly.The Pig framework is apart from top cover 270mm, and vibrator designs behind optimization test, and it is made of housing, end cap and the rotor that is positioned at wherein.Inlet, outlet is arranged on the housing.Housing internal diameter φ 80mm, inner width

, rotor diameter φ 70mm has groove, and endoporus φ 28mm is wide

Its principle is after feeding compressed air from air inlet, its rotor to be moved in the housing track, impacts housing and produces dither.Vibrator is with bolting or be welded on Pig framework, card center, and Pig frame, card hang with spring and housing respectively and connect.Ash bucket size suitable for reading is identical with filter, uses Bolt Connection.The dark 1.2m of ash bucket, 55 ° of gradients.The high 1.6m of base support.Filter chamber and base ash bucket are the normal carbon steel construction piece, and the connection place is airtight with the sponge rubber pad.The ash bucket bottom is connected to the ash discharge conveying worm.Manhole, door are established in the top cover of filter chamber and side, easy access vibrator, filter bag.

Claims

1, pneumatic rapping sack cleaner is made the filter bag ash removal rapping apparatus with pneumatic roll-type vibrator, is by air shaker [1], and filter chamber [2], ash bucket [3] is formed.It is characterized in that air shaker [1] is installed on the card [5] of the top of the Pig framework [4] in the filter chamber [2] or filter bag bottom, or on the card [5] of the top of Pig framework [4] and filter bag bottom air shaker [1] is installed simultaneously.
