Description

Efficient modularized bag-type dust collector Technical Field The invention relates to the technical field of bag-type dust collectors, in particular to a modularized efficient bag-type dust collector. Background The bag-type dust collector is used as high-efficiency and mature industrial flue gas purifying equipment, is widely applied to the heavy industrial fields of electric power, steel, cement, chemical industry, metallurgy and the like, and is core equipment for controlling the discharge of productive dust and meeting environmental protection standards. The working principle is that the filter bag made of fiber filter materials is utilized to filter dust-containing gas, so that dust is trapped on the surface of the filter bag, and purified gas is discharged through the fiber gaps of the filter bag. The cloth bag replacement steps of the prior large cloth bag dust remover are as follows: (1) The top cover plate of the dust remover needs to be opened by a crane, operators need to climb onto the firm pattern plate cross beam along the ladder stand, and the safety belt is tied. And releasing the fixed clamp, the pressing plate or the spring ring at the top of the bag cage by using special pliers. The bag cage is extracted vertically and stably upwards by both hands, so that the hole of the flower plate is prevented from being scraped and bumped. If the clamping stagnation occurs, the rubber hammer is used for lightly vibrating, and the rough operation is forbidden. The taken old bags are orderly stacked. (2) The old filter bag is lifted out of the hole of the flower plate. The action is light and slow in the whole process, the dust flying is reduced to the maximum extent. The old filter bag is immediately filled into ton bags for sealing. (3) And taking out the new filter bags one by one in the clean area, and strictly prohibiting the filter bags from being dragged on the ground. The final protective sleeve of the filter bag can be removed before installation. Hoisting the new filter bag to the top of the bag-type dust collector, and fully pinching the elastic expansion ring at the mouth of the new filter bag to align with the holes of the pattern plate. The filter bag is protected by two hands, so that the filter bag naturally, vertically and twist-free passes through the holes of the pattern plate. When the piston ring passes completely, the piston ring is loosened to open naturally. The ring is pressed by hand evenly to ensure that the ring is completely attached to the circumference of the hole of the checkered plate, and the click sound or the uniform elasticity is heard. "one is attached, one is checked, and one is sealed. (4) The bag cage is hoisted back to the top of the bag dust collector again, the bottom of the bag cage is carefully placed into the mouth of the filter bag, and the bag cage is ensured to be always positioned in the center of the filter bag by using a special guide sleeve or being assisted by a lower person. The bag cage is slowly and straightly inserted into the filter bag until the top protective cap of the bag cage is contacted with the flower plate, and the fixing device at the top of the bag cage is installed and fastened. The existing workers are required to ascend and hoist and replace, the replacement difficulty is high, the replacement efficiency is low, the replacement hazard degree is high, dust generated during replacement is easy to fly, the dust on the replacement site is large, the later-period long-time cleaning is required, and the influence on the health of the workers is large. In China patent (bulletin number: CN 115501700B), a cloth bag replacing device for a cloth bag dust remover is disclosed, and comprises a supporting frame and a lifting frame, wherein the supporting frame comprises a cross beam, supporting legs are arranged at two ends of the cross beam, the lifting frame is in sliding fit with the cross beam up and down, a first air cylinder is connected between the cross beam and the lifting frame, a lifting rod is arranged on one side of the lifting frame, the lifting rod comprises a sleeve rod, the sleeve rod is connected with the lifting frame, a supporting head is arranged at the lower end of the sleeve rod, and the supporting head is matched with a bag cage for fixing the cloth bag. The support head through the lifting rod lower extreme can be automatic with bag cage between fixed, can pull out sack and bag cage from the dust removal incasement under the effect of lifting frame and put back, the bag cage is direct to be changed on the lifting rod, and the device is put back to the dust removal incasement again with bag cage and sack after changing the sack, and the manual work only needs to carry out the change operation of new and old sack, has reduced manual operation to improved efficiency, convenient to use is more convenient, swift. The application discloses external equipment, if the external equipment is matched with a large-sized bag-type
