Description

Technical Field

[0001] The utility model relates to the technical field of filter bags, in particular to a film-coated fluorometh needle-punched felt filter bag. Background Art

[0002] Fluorometh needle felt is a mixture of two or more high temperature resistant fibers and layered composites to achieve higher and newer physical and chemical properties; the trade name of the composite high temperature resistant needle-punched filter felt is determined to be FMS (Fluorometh).

[0003] The patent document with the prior art publication number CN216630035U provides a coated fluoromethan needle felt filter bag, comprising a frame and a filter bag, a ring body is installed on the top of the outer wall of the frame, and a bag head ring is integrally formed on the top of the filter bag, characterized in that a cavity is opened inside the ring body, an elastic component is installed inside the cavity, and the top of the elastic component is fixed to the bag head ring. When the filter bag is impacted, the elastic tissue is stretched by the bag head ring. When a large amount of external material enters the filter bag, the utility model pulls the filter bag downward by the impact force of the material, and then the bag head ring rises and the elastic component is stretched to reduce the impact force, thereby avoiding the impact force directly acting on the top of the filter bag to cause tearing, which is beneficial to avoid the impact force during the filtering of large quantities of materials causing tearing on the filter bag mouth, and is beneficial to improving the filter bag effect of the filter bag.

[0004] However, during the use of the existing coated fluoromethac needle felt filter bag, the filter bag will be damaged after filtering for a period of time. At this time, the filter bag needs to be replaced. When replacing the filter bag, it is not easy to disassemble the filter bag, so the filter bag needs to be replaced as a whole, which is not conducive to material saving. For this reason, we propose a coated fluoromethac needle felt filter bag. Utility Model Content

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a coated fluoromethan needle felt filter bag, comprising a mounting sleeve 2, a through opening 5 being opened at the top of the mounting sleeve 2, a mounting tube 6 being fixedly connected to the inner side of the mounting sleeve 2, a mesh frame 7 being fixedly connected to the bottom end of the mounting tube 6, a mesh sleeve 8 being fixedly connected to the outer side of the mesh frame 7, a mounting opening 201 being opened between the mounting sleeve 2 and the mounting tube 6, a filter bag body 1 being fixedly connected to the mounting sleeve 2 and the mounting tube 6 through the mounting opening 201, a filter bag bottom 102 being fixedly connected to the bottom end of the filter bag body 1, a nut sleeve 3 being threadedly connected to the outer side of the mounting sleeve 2, and a fixing sleeve 4 being fixedly connected to the bottom of the nut sleeve 3.

[0024] In the present embodiment, specifically, a filter bag ring 101 is fixedly connected to the inner side of the top end of the filter bag body 1, and the filter bag ring 101 is a circular structure. When the filter bag body 1 is pulled downward through the filter bag ring 101, the gap between the fixing sleeve 4 and the mounting tube 6 is smaller than the filter bag ring 101, thereby preventing the filter bag body 1 from being separated from the mounting tube 6.

[0025] In this embodiment, specifically, the nut sleeve 3 and the fixing sleeve 4 are an integrated structure, and the fixing sleeve 4 gradually becomes smaller from top to bottom. When the fixing sleeve 4 and the mounting tube 6 are closer, the gap between the fixing sleeve 4 and the mounting tube 6 will become smaller, and the filter bag body 1 between the fixing sleeve 4 and the mounting tube 6 will be firmly fixed.

[0026] In the present embodiment, specifically, three mesh sleeves 8 are provided, the three mesh sleeves 8 are of the same size, and the three mesh sleeves 8 are arranged equidistantly. The mesh sleeves 8 support the filter bag body 1 into a cylindrical shape, and at the same time play a shaping and limiting role for the mesh frame 7.

[0027] In this embodiment, specifically, the diameter of the mounting tube 6 is matched with the inner diameter of the filter bag body 1 , and the mounting tube 6 is movably connected to the filter bag body 1 , so that the mounting tube 6 and the filter bag body 1 can be better installed together.

[0028] In the present embodiment, specifically, four grid frames 7 are provided, the lengths of the four grid frames 7 are the same, and the four grid frames 7 are arranged equidistantly. The grid frames 7 can better support the filter bag body 1 and avoid deformation of the filter bag body 1.

[0029] Working principle: After the utility model is installed, first check the installation, fixation and safety protection of the utility model. When using the coated fluorometh needle felt filter bag, the staff will sleeve the top end of the filter bag body 1 on the outside of the mounting tube 6, and then place the top end of the filter bag body 1 in the mounting port 201, and then install the nut sleeve 3 on the mounting sleeve 2. When the nut sleeve 3 is rotated toward the mounting sleeve 2, the fixing sleeve 4 will also move upward. Because the fixing sleeve 4 gradually becomes smaller from top to bottom, the closer the fixing sleeve 4 is to the mounting tube 6, the smaller the gap between the fixing sleeve 4 and the mounting tube 6 will be, and the filter bag body 1 between the fixing sleeve 4 and the mounting tube 6 will be firmly fixed. When the filter bag body 1 needs to be replaced, the staff only needs to remove the nut sleeve 3 from the mounting sleeve 2, and then push the filter bag body 1 downward to remove the filter bag body 1, thus completing the use process of the utility model. The utility model has a simple structure and is safe and convenient to use.
