Description

Technical Field

[0001] This utility model relates to the technical field of dust collector bag mounting frame, specifically to a metal filter bag frame. Background Technology

[0002] Dust collector bag frames are used in dust collectors in industries such as chemical, metallurgy, building materials, steel, cement, and thermal power generation. The quality of the bag frame directly affects the service life of the dust collector bag and the dust removal efficiency of the bag filter, making it one of the most important components of a dust collector.

[0003] For example, CN220690013U discloses a dust collector bag frame bottom fixing structure, including a dust collector bag frame and a fixing tube set on a base. The fixing tube is provided with a fixing mechanism for fixing the dust collector bag. The fixing mechanism includes multiple fixing grooves opened on the side wall of the dust collector bag, and a fixing plate is slidably connected to each fixing groove. The fixing tube is provided with a driving mechanism for driving each fixing plate. Under the driving action of the driving mechanism, the dust collector bag is fixed by the clamping action of the fixing plates. The operation is simple and convenient. Moreover, the entire fixing mechanism is designed as an integrated unit, eliminating the need to assemble individual parts. This not only improves the efficiency of fixing and disassembling the dust collector bag, but also avoids the risk of loss due to the dispersion of parts, thus further bringing convenience to the fixing of the dust collector bag.

[0004] However, in implementing the relevant technology, the following problems were found in the above-mentioned dust collector bag frame bottom fixing structure: it is difficult to adjust and expand the dust collector bag fitted on the metal frame to support and fix it outward, which causes wrinkles to appear when the dust collector bag is used, affecting its use and reducing the stability of the dust collector bag. Therefore, a metal filter bag frame is proposed. Utility Model Content

[0005] This utility model proposes a metal filter bag frame, which solves the problem in related technologies that it is difficult to adjust, expand, support and fix the dust collector bag fitted on the metal frame outward, which leads to wrinkles in the dust collector bag during use, affects its use and reduces the stability of the dust collector bag.

[0006] The technical solution of this utility model is as follows: A metal filter bag frame, comprising: a bottom circular frame, a top circular frame and a plurality of metal frame rods, wherein the plurality of metal frame rods are arranged in a circular array between the bottom circular frame and the top circular frame;

[0007] The top circle of the bottom circular frame has multiple mounting slots arranged in a sequential array, and the multiple mounting slots are fixedly connected to the bottom ends of multiple metal frame rods. The bottom circle of the top circular frame has multiple mounting slots arranged in a sequential array, and the multiple mounting slots are fixedly connected to the top ends of multiple metal frame rods.

[0008] The bottom circular frame, the top circular frame, and the multiple metal frame rods are all equipped with a support mechanism inside.

[0009] A fixing mechanism is provided at the top of the top circular frame.

[0010] Preferably, the support mechanism includes a cross-shaped plate one that fixes the case inside the bottom circular frame, a cross-shaped plate two that fixes the case inside the top circular frame, and a rotating rod that is rotatably connected between the cross-shaped plate one and the cross-shaped plate two. The top end of the rotating rod rotatably passes through the cross-shaped plate two and is fixedly connected to a handle.

[0011] Preferably, the outer side wall of the rotating rod is provided with multiple external threads spaced apart from top to bottom, and the outer side wall of the rotating rod is fitted with multiple internal thread sleeves, which are threadedly connected to the multiple external threads. A circular push plate is fixedly installed on the outer side of the internal thread sleeve.

[0012] Preferably, a sliding rod is fixedly installed between the first cross-shaped plate and the second cross-shaped plate, and multiple sliding plates are slidably connected to the outer wall of the sliding rod, with the multiple sliding plates being fixedly connected to the multiple internal threaded sleeves.

[0013] Preferably, the fixing mechanism includes a feed hopper fixedly installed on the top of the top circular frame and a circular baffle fixedly installed on the bottom of the outer side wall of the feed hopper.

[0014] Preferably, the fixing mechanism further includes a clamp, on which a hand-held fixing wire is provided.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] By manually rotating the handle, the rotating rod rotates, causing the internal thread to engage with the external thread for threaded movement, and the sliding plate to slide on the sliding rod, causing the circular push plate to move downwards. The circular push plate pushes the metal frame rod to deform and expand outwards, causing the dust collector bag fitted on the metal frame rod to expand outwards for support and fixation. This effectively prevents wrinkles from forming on the dust collector bag, thus improving the stability of the dust collector bag in use. Attached Figure Description
