Dust collectors are commonly used facilities in boilers and industrial production. During dust removal, the filter bag of the dust collector is a key part of the dust collector operation process. Usually, the cylindrical filter bag is vertically suspended in the dust collector. When the dust-laden gas passes through the dust collector, the dust is captured on the outer surface of the filter bag, and the clean gas enters the filter bag through the filter material. There is a cage inside the filter bag to support the filter bag and prevent the filter bag from collapsing. The existing dust collector filter bag sometimes moves and falls off. Therefore, a dust collector filter bag buckle anti-falling mechanism is particularly needed.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5 The utility model provides a technical solution: a dust collector filter bag buckle anti-drop mechanism, comprising a filter bag 1, a shell 2 is fixedly connected to the upper surface of the filter bag 1, an anti-drop mechanism 3 is arranged on the upper surface of the shell 2, a frame 4 is installed on the inner surface of the filter bag 1, and an adjustment mechanism 5 is arranged at one end of the frame 4;

[0020] The anti-falling mechanism 3 includes a fixing plate 301, a limiting groove 302, a fixing block 303, a slot 304, a spring 305 and a latch 306. The upper surface of the housing 2 is fixedly connected with the fixing plate 301, the inner surface of the filter bag 1 is provided with a limiting groove 302, the upper surface of the fixing plate 301 is fixedly connected with the fixing block 303, one side surface of the fixing block 303 is provided with a slot 304, one side surface of the slot 304 is fixedly connected with a spring 305, and one end surface of the spring 305 is fixedly connected with a latch 306. The plate 301, the limiting groove 302, the fixing block 303, the slot 304, the spring 305 and the latch 306 are arranged so that when the filter bag 1 is fixedly installed, the filter bag 1 is installed from the installation opening of the shell 2. When it is installed downward, it passes through the fixing block 303 on the fixing plate 301. The filter bag 1 will squeeze the latch 306 and compress the spring 305, so that the latch 306 shrinks into the slot 304. When the latch 306 passes through the limiting groove 302 on the filter bag 1, it pops out and the latch 306 is stuck in the limiting groove 302, thereby fixing the filter bag 1 to prevent it from falling off.

[0021] Furthermore, the adjusting mechanism 5 includes a support rod 501, a telescopic rod 502, a fixed shell 503, a clamping shell 504 and a clamping block 505. One end of the skeleton 4 is fixedly connected to the support rod 501, the inner surface of the support rod 501 is slidably connected to the telescopic rod 502, the outer surface of the support rod 501 is threadedly connected to the fixed shell 503, the upper surface of the fixed shell 503 is fixedly connected to the clamping shell 504, and the outer surface of the telescopic rod 502 is fixedly connected to the clamping block 505. 502, the fixed shell 503, the clamping shell 504 and the clamping block 505 are arranged. When the skeleton 4 is inserted to support the filter bag 1, the fixed shell 503 is rotated to loosen the clamping shell 504, so that the clamping block 505 is loosened. At this time, the telescopic rod 502 can be adjusted up and down to adjust the length of the skeleton 4. When it is adjusted to a suitable height, the fixed shell 503 is tightened, and the clamping shell 504 will clamp the clamping block 505, thereby fixing the telescopic rod 502, so that the skeleton 4 can reach a suitable length to support different filter bags 1.

[0022] Furthermore, the inner wall size of the slot 304 matches the outer wall size of the latch 306, and the filter bag 1 is snap-connected with the fixing plate 301. Through the setting of the latch 306, the latch 306 can be snapped into the limiting slot 302 to achieve better fixation and anti-falling.

[0023] Furthermore, the spring 305 and the bolt 306 form a telescopic structure, and the fixing block 303 is symmetrically arranged with respect to the central axis of the fixing plate 301 . Through the arrangement of the fixing plate 301 , the fixing block 303 can be installed on the fixing plate 301 , so that the bolt 306 can fix the filter bag 1 conveniently.

[0024] Furthermore, the telescopic rod 502 and the clamping block 505 form a clamping structure, and the support rod 501 is threadedly connected to the fixed shell 503. Through the setting of the telescopic rod 502, the height of the telescopic rod 502 entering the support rod 501 can be adjusted up and down, so that the skeleton 4 can better support the filter bag 1.

[0025] Working principle: First, install the filter bag 1 from the installation opening of the shell 2. When installing downward, it passes through the fixing block 303 on the fixing plate 301. The filter bag 1 will squeeze the bolt 306 and compress the spring 305, so that the bolt 306 will retract into the slot 304, and the bolt 306 will pop out when passing through the limiting slot 302 on the filter bag 1. The bolt 306 is stuck in the limiting slot 302 to fix the filter bag 1 to prevent it from falling off. When the filter bag 1 is fixed and installed, it is necessary to insert the skeleton 4 to support the filter bag 1. Rotate the fixing shell 503 to loosen the clamping shell 504 to loosen the clamping block 505. At this time, the telescopic rod 502 can be adjusted up and down to adjust the length of the skeleton 4. When it is adjusted to a suitable height, tighten the fixing shell 503, and the clamping shell 504 will clamp the clamping block 505, thereby fixing the telescopic rod 502, so that the skeleton 4 can reach a suitable length to support different filter bags 1.
