Description

Technical Field

[0001] The utility model belongs to the technical field of metal filter bag installation, in particular to an installation structure for multi-section combined filter bags. Background Art

[0002] Metal filter bags are composed of a microporous flexible membrane, a perforated tube, a bottom seal, and a welded upper flange. The longest lengths range from 6.5 to 7.5 meters. Metal filter bags are used in dust removal chambers, which are designed as a sealed compartment divided into an upper and lower compartment by a panel. The metal filter bags are mounted on this panel.

[0003] To install the filter bag, a worker enters the upper chamber and stands on the ceiling. They insert the filter bag through the ceiling's mounting hole, allowing the bag's flange to rest on the ceiling. The flange is then tightened using screws and a pressure plate on the ceiling. A ceramic seal is placed between the flange and the ceiling. As you can see, the length of the filter bag determines the height of the upper chamber. Therefore, to reduce dust removal chamber manufacturing costs, longer metal filter bags (e.g., 7 meters long) are typically designed in two or three sections, each joined together using threaded connections.

[0004] When installing a multi-segment filter bag in the upper compartment, first insert the lower filter bag into the mounting hole on the panel and secure it in place. Then, manually raise the upper filter bag and align the outer threads of the upper filter bag with the inner threads of the lower filter bag, then tighten the threads to create a threaded connection. Once all the segmented filter bags are assembled, carefully place the entire filter bag onto the panel and secure it.

[0005] Whether it is multi-section splicing or the final filter bag installation, the verticality of the filter bag needs to be ensured. It is difficult to maintain verticality if it is fixed manually, and the labor intensity is also relatively high. Therefore, it is necessary to design a suitable installation structure to achieve relative fixation of the multi-section filter bag on the flower plate and maintain verticality when installing it. Utility Model Content

[0006] The purpose of the utility model is to provide a mounting structure for multi-section filter bags, so as to solve the problems existing in the prior art and achieve relative fixation of the multi-section filter bags on the flower plate and maintain verticality when the multi-section filter bags are installed.

[0007] In order to achieve the above objectives, the solution of the present invention is:

[0008] A mounting structure for multi-section combination filter bags, comprising a flower plate and a fixing tool; the flower plate is provided with a plurality of mounting holes, and a plurality of fixing bolts arranged around each mounting hole; the fixing tool comprises a pair of upper half rings, a pair of lower half rings, two pin shafts, a movable locking buckle, a connecting rod and a limit bolt; the two pin shafts are coaxially arranged up and down, and are respectively installed between the pivot ends of the upper half ring and the lower half ring, so as to respectively make the upper half ring and the lower half ring form a circular ring that can be opened and closed movably; a movable locking buckle is provided between the movable ends of the upper half rings; at least one connecting rod is provided between the upper and lower half rings that are opposite to each other; a limit bolt is provided on the outer wall of each lower half ring, and the limit bolt movably abuts against the fixing bolt to prevent the fixing tool from rotating.

[0009] The lower edge of the inner wall of the upper half ring is provided with an anti-slip flange.

[0010] The two ends of the connecting rod are respectively fixed to the upper half ring and the lower half ring by screws.

[0011] Four fixing bolts are arranged at equal angles around each mounting hole of the flower plate.

[0012] A limiting bolt is provided at the middle position of the outer wall of the lower half ring.

[0013] After adopting the above technical solution, the utility model has the following technical effects:
