The rotating shaft 306 is movably connected with a tightening bolt 308 through a threaded hole 307. The rotating shaft 306 is connected with a rotating member 309 through a rotating groove 310. A limiting groove 311 is opened at the exact middle position on the right side surface of the rotating member 309. The limiting member 302 is fixedly installed on the left side surface of the mounting frame 301. The limiting spring 303 is fixedly installed inside the limiting member 302. The limiting rod 304 is fixedly installed at the outer end of the limiting spring 303. The connecting frame 305 is fixedly installed on the right side surface of the mounting frame 301. The rotating shaft 306 is fixedly installed inside the connecting frame 305. The threaded hole 307 is opened inside the rotating shaft 306. The tightening bolt 308 is threadedly connected inside the threaded hole 307. The rotating groove 310 penetrates through both ends on the left side of the rotating member 309. The rotating groove 310 is rotatably connected to the outer wall of the rotating shaft 306. Both ends of the limiting groove 311 penetrate through limiting holes 312. The size of the limiting member 302 is adapted to the limiting groove 311. The size of the limiting rod 304 is adapted to the limiting holes 312.

[0022] The limiting member 302 is fixedly installed at the exact middle position on the left side of the mounting bracket 301, and the rotating member 309 is fixedly installed at the exact middle position on the right side of the mounting bracket 301. The limiting member 302 can be tightly inserted into the inside of the limiting groove 311. After the rotating member 309 stops rotating along the rotating shaft 306 through the rotating groove 310, by tightening the fastening bolt 308, the rotating member 309 is firmly clamped by both ends of the connecting frame 305.

[0023] Specifically, through the compression of the limiting spring 303, the limiting rod 304 can be retracted into the inside of the limiting member 302, so that the limiting member 302 can be inserted into the inside of the limiting groove 311 of the adjacent mounting bracket 301. Through the reset of the limiting spring 303, the limiting rod 304 is inserted into the limiting hole 312, realizing the connection between two adjacent filter bag bodies 1. At the same time, through the rotation of the rotating member 309 along the rotating shaft 306, the included angle between two adjacent filter bag bodies 1 can be adjusted to adapt to different usage spaces, with stronger flexibility.

[0024] Embodiment Two:

[0025] Please refer to the attached Figure 1 -attached Figure 2 On the basis of Embodiment One, it is further obtained that protective mechanisms 2 are arranged on both the inner and outer sides of the filter bag body 1. The protective mechanism 2 includes an elastic mounting member 201 and a protective sleeve 202. The bottom of the elastic mounting member 201 is fixedly installed at the upper end of the filter bag body 1. The outer wall of the elastic mounting member 201 is clamped inside the mounting bracket 301. A magnetic sheet 206 is magnetically attracted to the upper end of the elastic mounting member 201. A connecting rod 205 is fixedly installed at the bottom of the magnetic sheet 206. A spreading frame 204 is fixedly installed at the lower end of the connecting rod 205. The outer wall of the spreading frame 204 abuts against the inner wall of the filter bag body 1. An anti-corrosion coating 203 is fixedly installed on the inner wall of the protective sleeve 202, and the anti-corrosion coating 203 is fixedly installed on the outer wall of the filter bag body 1.

[0026] The elastic mounting member 201 can bend and deform, and can quickly return to its original shape. When installing the filter bag body 1, only need to bend the elastic mounting member 201, and after clamping it inside the mounting bracket 301, the elastic mounting member 201 will quickly return to its original shape, thereby enabling the filter bag body 1 to be stably installed on the mounting bracket 301.

[0027] Specifically, through the elastic mounting member 201, the filter bag body 1 can be quickly installed on the mounting bracket 301, reducing the disassembly and assembly time. The filter bag body 1 is protected by the protective sleeve 202 and the anti-corrosion coating 203, increasing wear resistance and anti-corrosion properties. The spreading frame 204 is used to help the filter bag body 1 maintain a specific shape, ensuring the uniform distribution and effective utilization of the filtering area.

[0028] Working principle of the utility model: The utility model is a blended filter bag for coal-fired thermal power plants. First, the elastic mounting part 201 is compressed so that the filter bag body 1 can be quickly installed on the mounting frame 301. The filter bag body 1 is protected by the protective sleeve 202 and the anti-corrosion coating 203. Then, the support frame 204 is inserted into the interior of the filter bag body 1. The magnetic suction sheet 206 is magnetically sucked on the upper surface of the elastic mounting part 201. When installing multiple groups of filter bag bodies 1, the limit rod 304 on the left side of a group of mounting frames 301 is pressed to compress the limit spring 303 until the limit rod 304 is in place. 04 is completely retracted into the interior of the limiting member 302, and then the limiting member 302 is inserted into the limiting groove 311 on the right side of an adjacent group of mounting frames 301. Subsequently, under the action of the limiting spring 303, the limiting rod 304 is inserted into the limiting hole 312 to complete the connection between the two adjacent groups of mounting frames 301. The angle between the two adjacent groups of mounting frames 301 is adjusted by rotating the rotating member 309 along the rotating shaft 306, thereby achieving the angle between the two adjacent groups of filter bag bodies 1. Finally, the fastening bolt 308 is tightened inside the threaded hole 307 to complete the angle fixation.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
