[0032] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0033] Example 1: A bag dust collector at the kiln tail, see Figures 1 to 5 , including a bag dust collector body 1, and also including a dust removal structure 2;

[0034] A plurality of dust removal structures 2 are sequentially arranged in the bag filter body 1;

[0035] The dust removal structure 2 includes a cloth bag 201;

[0036] The top of the bag 201 is connected to the circular hole on the mounting plate 101 fixed at the top of the bag dust collector body 1 through the positioning assembly 202;

[0037] The positioning assembly 202 includes a fixing ring 2021, a connecting ring 2023, a movable plate 2027 and a positioning block 2029;

[0038] The fixing ring 2021 is fixedly arranged on the top side of the circular hole on the mounting plate 101; the inner wall of the connecting ring 2023 is fixedly connected to the top of the cloth bag 201; the bottom ends of the four movable plates 2027 are respectively rotatably arranged on the top side of the fixing ring 2021 through the torsion springs 2028; the two ends of the torsion spring 2028 are respectively connected to the bottom end of the movable plate 2027 and the top side of the fixing ring 2021, and the elastic coefficient of the torsion spring 2028 is selected and used by the technicians in this profession according to the actual situation; the four positioning blocks 2029 are respectively fixedly arranged on the inner sides of the four movable plates 2027; among them, the four positioning blocks 2029 are snap-fitted with the four positioning grooves 2025 which are opened in a circular array on the outer wall of the connecting ring 2023.

[0039] The utility model has the advantages of quickly positioning the connecting ring 2023 after docking with the fixing ring 2021 and facilitating separation of the connecting ring 2023 by providing a fixing ring 2021, a connecting ring 2023, a movable plate 2027, a torsion spring 2028 and a positioning block 2029, thereby solving the problem that the mounting ring at the top of the cloth bag 201 and the mounting plate 101 are fixed with many screws, resulting in inconvenient operation when replacing the cloth bag 201.

[0040] Specifically, the positioning block 2029 is configured to have an arc-shaped snap-in side, which is matched with the positioning groove 2025. The arc-shaped snap-in side of the positioning block 2029 allows the connecting ring 2023 to be directly pushed in or pulled out when docking with the fixing ring 2021 or leaving the fixing ring 2021, so as to squeeze the positioning block 2029 to rotate outward, which is convenient for operation.

[0041] Furthermore, four guide rods 2022 are fixedly disposed in a circular array on the top side of the fixing ring 2021 , and four through holes 2024 are opened in a circular array on the connecting ring 2023 , and the guide rods 2022 are fitted in the through holes 2024 .

[0042] The utility model provides the guide rod 2022 and the through hole 2024 , and has the advantage that when the connecting ring 2023 and the fixing ring 2021 are docked, the guide rod 2022 passes through the through hole 2024 to position the docked connecting ring 2023 , so that the positioning block 2029 and the positioning groove 2025 are accurately docked.

[0043] Furthermore, the four movable plates 2027 and the four guide rods 2022 are staggered with each other; the rotation of the movable plates 2027 is not affected.

[0044] It is worth mentioning that two handles 2026 are symmetrically fixed on the top side of the connecting ring 2023 , and the connecting ring 2023 can be pushed in or pulled out conveniently by holding the handles 2026 .

[0045] Working principle: When using the device of the utility model to install the cloth bag 201, the cloth bag 201 is passed through the circular hole on the mounting plate 101, and the handle 2026 is held to dock the connecting ring 2023 with the fixing ring 2021. Before docking, the guide rod 2022 passes through the through hole 2024 accordingly, so that the connecting ring 2023 is stably pushed toward the fixing ring 2021, and the outer ring on the bottom side of the connecting ring 2023 contacts the arc-shaped positioning block 2029. The positioning block 2029 is squeezed outward, and the movable plate 2027 is rotated outward by the torsion spring 2028 until the connecting ring 2023 is docked with the fixing ring 2021. Under the action of the torsion spring 2028, the movable plate 2027 rotates, and the positioning block 2029 rotates accordingly to dock with the positioning groove 2025, so that the cloth bag 201 is positioned. When removing the cloth bag 201, hold the handle 2026 to pull out the connecting ring 2023, and the arc-shaped positioning block 2029 is squeezed out of the positioning groove 2025 after being subjected to an upward force on the inserted side. The movable plate 2027 is rotated outward by the torsion spring 2028 until the guide rod 2022 is separated from the perforation 2024, and the movable plate 2027 and the positioning block 2029 are rotated, and the cloth bag 201 is pulled out for replacement.
