Abstract
The utility model relates to a bag dust remover which is characterized in that a dust remover group box body is mechanically connected with a bag group, and a dust removing blower is arranged at the air outlet at the upper part of the dust remover group box body. The known bag dust remover mainly adopts mechanical rapping or pulse jetting to remove dust. The utility model improves the original dust removing blower into a blower capable of positive rotation and contrarotation, and the air volume produced by contrarotation is 2 times of that produced by positive rotation. When the dust accumulated on the surface of the bag amounts to a certain thickness, a control system issues an order to enable the blower to contrarotate, then the air volume 2 times of that produced by positive rotation is blown into the bag to rapidly inflate the bag and shake the bag, so as to rapidly remove the dust, thereby achieving a high dust removing effect. When the dust removing is accomplished, the blower resumes positive rotation to continuously remove dust, so as to simplify the structure of the dust removing device.
Description
Affiliated technical field
The utility model relates to a kind of bag-type dust collector.
Background technology
At present, the dust pelletizing system of industrial and mining enterprises is often used the fiber bag precipitator dedusting, and its operation principle is a negative pressure of utilizing blower fan to form, and dusty gas is sucked deduster, after the cloth bag filtration, dust is trapped in outside the bag, and cleaned air passes then enters atmosphere through blower fan, when the dust increase of cloth bag surface loading, when reaching certain resistance, send instruction by control system and carry out deashing, break away from cloth bag, discharge after falling into ash bucket thereby make attached to the dust on the cloth bag.
The following several purge modes of the many employings of known sack cleaner:
The mechanical vibrator formula: utilize machinery or electromagnetic shock to make cloth bag produce vibration and the device of deashing, this type of apparatus features is by vibration, reaches the deashing purpose thereby make cloth bag produce distortion.
The pulse jet formula: with compressed air is power, utilizes pulse blowing valve at the abrupt release compressed air stream, induces auxiliary air to inject cloth bag.Filter bag is sharply expanded, rely on gas shock to make cloth bag shake and reach the deashing purpose.
Summary of the invention
The purpose of this utility model is to provide a kind of sack cleaner, traditional vibration dust-cleaning, pulse jetting deashing device have been cancelled, adopt a kind of air output that just changes, reverses, the different dedusting fan of blast, dedusting when blower fan is just changeing, blower fan when counter-rotating air quantity two times when just changeing, utilize the blower fan counter-rotating to produce air quantity, be blown into the purpose that cloth bag reaches deashing.
The beneficial effects of the utility model are: when the dust of cloth bag surface detention reached certain thickness, the cloth bag resistance increased.When pressure was increased to certain numerical value, control system can be sent signal, the counter-rotating of order blower fan, beginning deashing.The deashing time is 3～5 seconds (deashing time length can be adjusted).After deashing stopped, blower fan recovered just changeing the continuation dedusting, has simplified the structure of deashing device.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
This figure is a front view of the present utility model
1. dedusting unit casings among the figure, 1-1 card, 1-2 dedusting unit air inlet, 1-3. air-purifying chamber, 2. cloth bag, 3. blower fan, 3-1 draught fan impeller, 3-2 blower motor, 4. ash bucket, 4-1 ash discharging hole.
Specific implementation method
In the drawings, dedusting unit casing (1), card (1-1), dedusting unit air inlet (1-2) is welded as a whole, and cloth bag (2) adopts mechanical attachment with card (1-1), and blower fan (3) is installed in air outlet place, dedusting unit casing (1) top.The dirt source point of dust pelletizing system connects with dedusting unit air inlet (1-2) by pipeline, dusty gas is under the suction function that blower fan (3) produces, enter dedusting unit casing (1) through dedusting unit air inlet (1-2), dust-contained airflow after cloth bag (2) filters, the air that is cleaned through air-purifying chamber (1-3), enter blower fan (3) and discharge.When the dust that is trapped in cloth bag (2) outer surface reaches certain thickness, the control system blower motor (3-2) of giving an order drives draught fan impeller (3-1) counter-rotating, to spray into greater than the pure air (winding-up air-flow) of 2 times of suction airstream and make cloth bag that the shake distortion takes place in the cloth bag (2), dust falls into ash bucket (4), discharges through ash discharging hole (4-1).
Claims (1)
1. sack cleaner is characterized in that: the blower fan unit has the effect of just changeing exhausting counter-rotating air blast, both can be as the dedusting fan of suction dusty gas, and also can be as the back blowing machine of deashing.
