[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example

[0025] like Figures 1-6As shown, this utility model provides a technical solution: a PTFE filter bag for flue gas dust removal in a glass factory, comprising a filter bag body 1, two filter elements 2 disposed on the top of the filter bag body 1, an mounting component 3 disposed on the top of the filter bag body 1, a positioning mechanism 4 for positioning the filter elements 2 disposed on the top of the filter bag body 1, and an installation mechanism 5 for installing and fixing the filter elements 2 disposed on the top of the filter bag body 1. The installation mechanism 5 includes a fixing ring 51 fixedly connected to the top of the filter bag body 1 and a screw rotatably connected to the filter bag body 1. 52, and an insertion hole 510 opened on the filter element 2. The screw 52 is externally threaded to a retainer 55. The bottom of the retainer 55 is fixedly connected to an insertion rod 54. The retainer 55 is externally slidably connected to a limit rod 56. The top of the limit rod 56 is provided with an external thread 57. The external thread of the external thread 57 is connected to a fixing cap 58. The bottom of the screw 52 is fixedly connected to a hexagonal bolt 59. There are two retainers 55. One end of each retainer 55 is threaded to the screw 52, ​​and the other end of each retainer 55 is slidably connected to the limit rod 56. Externally, the two card holders 55 have the same dimensions. There are two sets of insertion rods 54 and four insertion holes 510 in each set. The two sets of insertion holes 510 are respectively located on the two filter elements 2, and their dimensions are adapted to the two sets of insertion rods 54. The two sets of insertion rods 54 are fixedly connected to the bottom of the two card holders 55, and are inserted into the inner side of the two sets of insertion holes 510. There are two external threads 57 and two fixing caps 58. The two external threads 57 are respectively located on the top of the screw 52 and the limiting rod 56, and the two fixing caps 58 are... The fixed cap 58 is threaded to the outside of the two external threads 57 respectively. The limiting rod 56 is fixedly connected to the top of the filter bag body 1. The end of the screw 52 away from the external thread 57 passes through the filter bag body 1 and is fixedly connected to the hexagonal bolt 59. The screw 52 is mounted on the filter bag body 1 through the bearing seat and is rotatably connected to the filter bag body 1. The size of the fixing ring 51 and the two card seats 55 are adapted to the two filter elements 2. The two filter elements 2 are respectively inserted into the inner side of the fixing ring 51 and the bottom card seat 55. Two handles are fixedly connected to the outer side of the two filter elements 2.

[0026] With the above technical solution, during use, the user can install the two fixing caps 58 on the top of the screw 52 and the limiting rod 56 respectively through the two external threads 57. Then, insert the electric wrench into the hex bolt 59, and then drive the hex bolt 59 to rotate. The rotation of the hex bolt 59 drives the screw 52 to rotate, and the rotation of the screw 52 drives the two retaining seats 55 to move through the limiting rod 56. The movement of the retaining seats 55 will separate them from the filter element 2. Then, the user can remove the two filter elements 2 from the retaining seats 55 and the fixing ring 51, and then install a new filter. The filter element 2 is placed on the fixing ring 51 and the bracket 55 by the positioning mechanism 4. Then, the user can move the two brackets 55 back to their original positions by rotating the hex bolt 59 in the opposite direction. At this time, the two brackets 55 will fix the two filter elements 2 again. At the same time, the user can remove the external thread 57 and the fixing cap 58. Then, by continuously rotating the hex bolt 59, the two brackets 55 can be disassembled. This makes it convenient to disassemble and assemble the filter element 2, and also makes it convenient for the user to replace the brackets 55, thus greatly improving the practicality.

[0027] like Figures 1-5 As shown, the positioning mechanism 4 includes four positioning rods 41 that are fixedly connected to the top of the fixing ring 51 and the top of the top bracket 55 at equal angles. Positioning holes 42 are inserted into the outside of the positioning rods 41. The number of positioning holes 42 is the same as that of the positioning rods 41. The two sets of positioning holes 42 are respectively opened on the two filter elements 2, and the positions of the two sets of positioning holes 42 correspond to the two sets of positioning rods 41.

[0028] With the above technical solution, during use, the user can separate the card holder 55 from the filter element 2 through the installation mechanism 5, and then place the two filter elements 2 on the fixing ring 51 and the bottom card holder 55 respectively, so that the positioning holes 42 on the two filter elements 2 are inserted into the positioning rods 41 on the fixing ring 51 and the card holder 55. At this time, the positioning of the filter element 2 can be completed. Then, the filter element 2 can be installed and fixed again through the installation mechanism 5, thereby realizing the positioning of the filter element 2, which facilitates subsequent installation.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
