Technical Field

[0001] The utility model relates to the technical field of dust removal cloth bags, in particular to a cloth bag for facilitating dust removal in a thermal power plant. Background Technique

[0002] The dust removal cloth bag is an important filtering element used in industrial dust removal equipment. It is usually made of various fiber materials, such as polyester fiber, glass fiber, aramid fiber, etc. These fibers are woven or needled through specific processes to form a cloth bag structure with a certain porosity and filtering performance.

[0003] During the operation of the cloth bag dust removal device in a thermal power plant, when the cloth bag is blocked, resulting in a decrease in dust removal efficiency, the cloth bag needs to be replaced or cleaned. The traditional cleaning methods are mainly divided into two types. One is pulse jet cleaning, and the other is reverse air blowing cleaning. The traditional dust removal and cleaning are relatively difficult and not easy to replace. Summary of the Invention

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Referring to Figures 1 - 5 , a dust bag for facilitating dust removal in a thermal power plant, including a bracket 1. A plurality of monomer structures 2 are installed inside the bracket 1. A number of spring A8 are installed inside each monomer structure 2. Both ends of each spring A8 are fixedly connected to the adjacent fixing ring 201. Each spring A8 is in a static state. The spring A8 is used to provide a supporting force for the fixing ring 201 and can also ensure the overall vibration, which is beneficial to ash cleaning. Every two monomer structures 2 are in close contact with each other. Each monomer structure 2 includes two fixing rings 201 and a short cloth bag 202. The two fixing rings 201 are fixedly connected to the short cloth bag 202. The plurality of short cloth bags 202 adopt a gradient pore structure, and the pores of the plurality of short cloth bags 202 gradually increase. The surface pores are slightly smaller to ensure the filtration accuracy, and the internal pores gradually increase to facilitate the falling off of dust. Four fixing rods 9 are inserted into the inside of the plurality of fixing rings 201. Nuts 11 are threadedly connected to both ends of each fixing rod 9. The four fixing rods 9 are used to limit the positions of the plurality of monomer structures 2, and multiple groups of nuts 11 are used to ensure the disassembly of the fixing rods 9. A spring B10 is fixedly connected between each nut 11 and the adjacent fixing ring 201. The spring B10 is in a compressed state, and the elastic deformation of the spring B10 can provide a thrust for the fixing ring 201, improving the stability of the plurality of monomer structures 2. Each short cloth bag 202 is in a corrugated shape, and a tightening ring 3 is sleeved on the outer surface of each short cloth bag 202. The tightening ring 3 is a soft ring that can be tightened and stretched. A plurality of through holes 4 arranged in a circular pattern are opened inside each short cloth bag 202. A number of rotating wheels 5 arranged at equal distances are placed inside the bracket 1. Each rotating wheel 5 is used for rotation. A rotating rod 7 is fixedly connected inside the plurality of rotating wheels 5. The rotating rod 7 is connected to an external motor. By driving the rotating rod 7 to rotate by the external motor, the plurality of rotating wheels 5 can be rotated, and thus the plurality of tightening rings 3 can perform tightening actions. A pull rope 6 is slidably connected inside each through hole 4. One end of each pull rope 6 is fixedly connected to the adjacent tightening ring 3, and the other end is fixedly connected to the adjacent rotating wheel 5.

[0022] Working principle:

[0023] When in use, external air enters the inside of the plurality of short cloth bags 202 from the outside. The pores of the short cloth bags 202 are used for air to enter and are discharged from both ends thereof. The short cloth bags 202 are used to isolate dust and foreign objects, playing a role in dust removal.

[0024] Immediately afterwards, when it is necessary to clean the short cloth bag 202, an external flushing device is installed at the upper end of the whole, and flushing is carried out by means of pulses. The multiple short cloth bags 202 are provided with a gradient pore structure, with slightly smaller surface pores to ensure the filtration accuracy, and gradually increasing internal pores to facilitate the shedding of dust. By setting the short cloth bags 202 to be corrugated, the surface area is increased, and at the same time, the distribution of air flow and dust is changed, which is beneficial to dust cleaning. Then, an external motor is connected to the upper end of the rotating rod 7, and the rotating rod 7 is driven to rotate by the motor. The rotating rod 7 drives multiple rotating wheels 5 to rotate, and the multiple rotating wheels 5 respectively drive multiple groups of pull ropes 6 to tighten. The multiple groups of pull ropes 6 are respectively tightened evenly around the tightening rings 3, so that the tightening rings 3 uniformly stretch the short cloth bags 202, increasing the pores of the short cloth bags 202 and making it easier to clean the dust, thus solving the problem that dust removal and cleaning are relatively difficult.

[0025] Finally, when replacement is needed, only need to take out multiple nuts 11 and take out the four fixing rods 9 from the multiple monomer structures 2, which is simple and fast, thus solving the problem that replacement is not easy.

[0026] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0027] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
