Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction, in particular to a high-efficiency dust reduction device for the production of fireworks and firecrackers. Background Art

[0002] During the use of the bag dust collector, when the bag is replaced, the operator enters the top of the flower plate through the inspection door above the dust collector, first pinches the spring coil on the upper mouth of the bag into a concave shape, and then pulls the bag out as a whole through the hole in the flower plate, and then lowers the new bag into the bag chamber through the hole in the flower plate, and then pinches the spring coil on the upper part of the bag opening into a concave shape, puts it into the hole in the flower plate and restores the spring coil, and then puts the supporting frame of the bag into the bag opening, and uses screws to lock the frame to fix the frame in the hole in the flower plate while clamping the bag to limit the position. Therefore, when the bag is disassembled and replaced, the screws need to be removed first. However, since there are often a large number of bags in the holes in the flower plate, it is more troublesome for the staff to disassemble them repeatedly. Utility Model Content

[0003] The purpose of the utility model is to solve the problem that when replacing the bag of the existing bag dust collector during use, the operator enters the top of the flower plate through the inspection door above the dust collector, first pinches the spring ring on the upper opening of the bag into a concave shape, then pulls the bag out as a whole through the flower plate hole, then puts the new bag into the bag chamber through the flower plate hole, then pinches the spring ring on the upper part of the bag opening into a concave shape, puts it into the flower plate hole and restores the spring ring, then puts the supporting frame of the bag into the bag opening, and fixes the frame in the flower plate hole with screws. At the same time, the cloth bags are clamped and limited, so when the cloth bags are disassembled and replaced, the screws need to be removed first. Since there are often a large number of cloth bags in the flower plate holes, it is troublesome for the staff to repeatedly disassemble them. Therefore, a high-efficiency dust reduction device for fireworks and firecrackers production is proposed, including a bag dust collector shell, a flower plate rack, cloth bags, and a skeleton assembly. A flower plate rack for installing cloth bags is installed inside the bag dust collector shell, cloth bags are placed inside the flower plate rack, and a skeleton assembly is placed inside the cloth bags. Quick-install mechanisms are installed on the skeleton assembly and the flower plate rack.

[0004] Preferably: the quick-loading mechanism includes an L-shaped cylinder 201, and multiple L-shaped cylinders 201 are installed on the middle part of the flower plate rack 2. The L-shaped cylinder 201 is wide at the top and narrow at the bottom, and is concave from the inside to the outside. The quick-loading mechanism also includes a T-shaped pull ring 403. The skeleton assembly 4 is composed of a stepped cylinder 401 and a skeleton 402. The stepped cylinder 401 is also wide at the top and narrow at the bottom, and is concave from the outside to the inside. The outer diameter of the upper end of the stepped cylinder 401 is larger than the outer diameter of the upper end of the L-shaped cylinder 201. At least three holes are provided in the recessed part of the lower part of the stepped cylinder 401. A T-shaped pull ring 403 is slidably installed inside the hole. One end of the T-shaped pull ring 403 passes through the inner side of the stepped cylinder 401, and the other end of the T-shaped pull ring 403 is located in the hole at the lower part of the stepped cylinder 401, and the end is fixedly connected to a top block 405.

[0005] Preferably, a spring is installed between the top block and the hole in the recess at the bottom of the stepped cylinder, and a T-shaped pull ring passes through the center of the spring. Under normal conditions, the spring pushes the top block outward so that the top block is located in the recess of the L-shaped cylinder.

[0006] Beneficial effect: When it is necessary to remove and replace the bag inside the bag dust collector, the staff first inserts three fingers into the three T-shaped pull rings, and then pulls the three T-shaped pull rings inward. At this time, the three T-shaped pull rings will be pulled inward from the holes at the bottom of the step cylinder. The spring contracts, and the top block fixed to it will also be pulled inward to the inside of the hole at the bottom of the step cylinder. Then, the skeleton assembly can be directly taken out from the bag, realizing the quick removal of the bag. BRIEF DESCRIPTION OF THE DRAWINGS
