Description
Technical Field
The utility model relates to a sack cleaner especially relates to an impulse type sack cleaner.
Background
The bag-type dust collector is a dry dust filter, it is suitable for catching tiny, dry, non-fibrous dust, the sack is made of woven filter cloth or non-woven felt, utilize the filtering action of the fabric to filter the dusty gas, after the dusty gas enters the sack-type dust collector, the dust that the granule is big, the proportion is big, because the effect of gravity subsides, fall into the ash bucket, the gas containing tiny dust is when passing through the sack, the dust is detained, make the gas obtain purifying.
The prior pulse bag-type dust collector generally has two bag mounting modes, one is to fix the bag on a bag cage, and the other is to tightly clamp the bag on a mounting sleeve on a pattern plate and then press-fit the bag by using a protective cover on the upper part of the bag cage. In the first structure, the pattern plate is only provided with the pattern holes for clamping the bag cage, the structure is simple, the assembly is convenient, but because the cloth bag is arranged in the bag cage, when the air volume in the box body is large, the cloth bag can be sealed and pressed flat, and the filtering effect and the filtering capacity of the cloth bag are influenced; the mounting sleeve for mounting the cloth bag needs to be welded at the flower hole of the pattern plate, the manufacturing process of the pattern plate is complex, and in the using process, the bag cage can well open the cloth bag inside the cloth bag to guarantee normal filtration of the cloth bag, so that the effective work of the cloth bag dust remover is guaranteed.
The cloth bag of the existing pulse type cloth bag dust remover is generally sleeved on a mounting sleeve of a card, a spring ring on the upper part of a bag opening is used for pressing the circumference of the mounting sleeve, then a bag cage is sleeved in the cloth bag, a protecting cover on the upper part of the bag cage is pressed on the mounting sleeve to realize the press fitting of the cloth bag, namely, the cloth bag is pressed through the spring ring and is pressed through the gravity of the bag cage. The resistance of the dust collector rises along with the continuous progress of filtration, when the resistance reaches a certain value, the ash removal controller sends an ash removal command, the lifting valve plate is closed at first, air inlet is cut off, then the ash removal controller sends a signal to the pulse electromagnetic valve, high-pressure reverse airflow used for removing ash is sent into the cloth bag along with the pulse valve, the cloth bag rapidly expands, and strong shaking is generated, so that dust on the outer side of the filter bag shakes off, and the purpose of removing ash is achieved. Because the ash removal frequency is high, the cloth bag frequently and strongly shakes, the relative motion between the top of the cloth bag and the mounting sleeve can be caused, a gap is sometimes generated between the top of the cloth bag and the mounting sleeve, and the airflow containing dust directly flows to the upper cavity from the gap and is discharged without being filtered, so that the filtering effect of the cloth bag dust remover is weakened, and unqualified gas is discharged. At present, a bag-type dust remover capable of ensuring that a bag is firmly fixed is urgently needed, so that the failure rate of the bag-type dust remover is reduced, and the continuous normal operation of the whole process is ensured.
Disclosure of Invention
