Abstract

The utility model relates to a centrifugal and rotary dust filter, belonging to a filtering device for dusty air. The utility model arranges a dust entering mouth at a conical barrel. The lower part of a dust filtering cloth bag is provided with an eccentric rotary plate. After the dusty air enters the dust filter, the dusty air is purified once in the conical barrel under the function of centrifugal action. The air with small quantity of dust floats upward and is purified by the dust filtering cloth bag for the second time. The dust adsorbed by the dust filtering cloth bag is vibrated to fall by the intermittent rotation of the eccentric rotary plate to achieve the self-clearing purpose. The utility model has the advantages of simple structure, good dust removing effect, low cost, small occupation of land, etc.

Description

Centrifugal rotation dust filter

The utility model relates to a kind of air cleaning dust filtration device, particularly a kind of dirt catcher that is used for grain and cereal process dust laden air.

Existing grain processing industry all will produce a large amount of dust laden airs when the various cereal crops site transport of processing, conventional dust removal and filtration method is to adopt picogram dragon or cloth bag dust filtration device, though this class cleaner can be finished the dedusting task, but filter clean rate variance, be unsuitable for the big occasion, particularly fiber bag precipitator of the long-pending amount of dirt, the dust containing capacity of its filter dirt cloth is limited, need often filter cloth to be cleared up, remove adhered dust on the filter cloth.Have on the abrasive dust production line of domestic introduction in recent years and a kind ofly can remove the dirt catcher that cloth bag adheres to dust automatically, by electronic valve control Venturi tube, auxiliary air pump produces automatic removing of pressure and adheres to dust, but this dirt catcher structure more complicated, automatically controlled required precision height, electric elements fragile rate height, cost height, power consumption is big, is unsuitable for medium-sized and small enterprises and uses.

The purpose of this utility model is to overcome the deficiency of above-mentioned deduster, provide a kind of novel structure, good dedusting effect, cost low, be easy to safeguard, and can in multiple industry, use centrifugal revolution dirt catcher.

The purpose of this utility model is realized by following mode: its agent structure still adopts the fiber bag precipitator structure, comprise conically shaped, housing and filter dirt cloth bag bundle, its dusty gas import is located on the conically shaped, filter dirt cloth bag bundle is located in the housing, and rotating disk is equipped with in cloth bag bundle bottom, and this rotating disk is hung on the fixed head of filter dirt cloth bag Shu Shangfang by flexible strand, center of turntable is equipped with turning cylinder, and its turning cylinder is by minitype motor driving and the eccentric that different counterweights constitute is housed.Its operation principle is: after dust laden air enters in the conically shaped from entering-dust mouth, along rotation of taper barrel and generation centrifugal force, form pressure differential at internal body, force air come-up dust backspin, dust is separated from air, reach the purpose of primary purification, and still contain a certain amount of dust in the air of come-up, carry out secondary filter by filter dirt cloth bag and purify, the dust that adsorbs on its filter dirt cloth bag shakes dust fall by rotating the intermittence of the rotating disk under it.

In the utility model, consider the inner space of conically shaped, can be with the part of micromachine as counterweight in the eccentric.

The utility model has the advantages that: novel structure, be skillfully constructed, good dedusting effect, cost are low, it is few to take plant area, dust removing effects is remarkable, overcome filter dirt cloth bag laying dust cleaning complex structure in the existing equipment, the shortcoming that additional device is many, and can in multiple industries such as grain processing and tobacco, tealeaves, food, flax, metallurgy, use.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is an eccentric rotating disk schematic diagram of the present utility model.

Implementation example: as shown in Figure 1, be a kind of 10000m that per hour handles ³Dirt catcher, its conically shaped 1 is provided with entering-dust mouth 2, bottom and dust exhausting fan 3 join, the top shell 4 of meeting sb. at the airport, casing 4 tops are equipped with a cloth bag fixed mount 11 and are gone out dirt tube 12, dust-exhausting port distributes on this fixed mount 11, filter dirt cloth bag 9 is housed respectively, filter dirt cloth bag 9 bottoms and eccentric rotating disk 8 join, eccentric rotating disk 8 is also hung on the fixed mount 11 by four flexible wire ropes, and eccentric rotating disk 8 centers are provided with turning cylinder 5, and eccentric 6 is housed on it, this eccentric 6 is an excentric sleeve 10 and an eccentrically mounted weight, and with the part of micromachine 7 as counterweight, the output shaft of micromachine 7 joins with belt and turning cylinder 5, drives turning cylinder 5 and rotates, and drive the intermittently swing of eccentric rotating disk 8, realize that vibration and collision are to remove the purpose of absorption dust on the cloth bag.
