Description

Pulse type bag dust collector

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

The to-be-solved technical problem of the utility model is to provide a can guarantee fixed firm pulsed sack cleaner of sack.

In order to solve the technical problem, the utility model discloses a well box, the lower part of well box is equipped with the ash bucket, the box is installed at the top of well box, the card is equipped with admittedly at the top of well box, a plurality of flower holes have been seted up on the card, the card upper surface corresponds every flower hole ring and is equipped with the installation cover, and every installation sheathes in and is equipped with the sack that stretches into in the well box, be equipped with the bag cage in the sack, the cover pressure equipment on bag cage upper portion is sheathe in at the installation, characterized by the lower edge ring of protecting cover is equipped with the lug that can press fitting at the card upper surface, be equipped with the pressure equipment board on the card, set up a plurality of through-holes that can supply bag cage upper portion to wear out on the pressure equipment board, the lower surface of pressure equipment board encircles the through-hole and is equipped with the heavy groove that suits with the size, the position of lug and makes the pressure equipment board compress tightly, Less than the external dimension of well box, well box wall upper surface ring is equipped with the subsidence district that can supply the peripheral card of pressure equipment board to go into, the tank wall upper surface parallel and level of the upper surface of pressure equipment board and well box, the lower surface pressure equipment of going up the box tank wall is at the upper surface of well box wall and pressure equipment board.

After the structure of the utility model is adopted, the utility model discloses well bag cage is protected and is covered and set up the pressure ear, and card upper portion sets up the pressure equipment board, and the pressure equipment board can compress tightly the pressure ear, and pressure equipment board and well box block can compress tightly the pressure equipment board when going up the box and being connected fixedly with well box to the realization further compresses tightly bag cage and sack, guarantees that the sack is fixed firm, avoids long-time back sack and installation cover to take place relative slip, influence the utility model discloses normal operating has reduced the fault incidence, improves the utility model discloses a job stabilization nature, the utility model discloses simple structure, installation, dismantlement are convenient.

The cross section of the middle box body is rectangular, and the flower holes are arranged in rows and columns, so that the installation of the press-mounting plate is facilitated.
