[0002] A bag filter is a dry dust filtration device that uses bag-shaped filter elements made of fibrous fabric to capture solid particles in dusty gas.

[0003] The main structures used for filtration in a bag filter include a frame and a filter bag. The filter bag covers the outside of the frame. The anti-torsion design is achieved by sewing reinforcing ribs between the frame and the filter bag. However, relying solely on this method still has shortcomings: under long-term alternating stress, the threads are prone to failure, which will affect the filtration effect on dirt.

[0004] Therefore, it is necessary to provide a new anti-torsion filter bag for bag filters to solve the above-mentioned technical problems. Utility Model Content

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please see Figures 1 to 5 The present invention provides an anti-torsion filter bag for a bag filter, which includes a frame 1 and a filter cloth 2 covering the outside of the frame 1.

[0031] The filter cloth 2 is cylindrical, and multiple elastic straps 22 are sewn onto the inner circumference of the filter cloth 2, forming an axial slot between the straps 22 and the filter cloth 2.

[0032] Positioning plugs 3 are fixed on the skeleton 1 with corresponding number and position of straps 22. The positioning plugs 3 can be inserted into the slot.

[0033] It should be noted that in this device, the filter cloth 2 covers the outside of the frame 1 to form a complete filtration structure;

[0034] The traditional method is still used for the installation and fixation of filter cloth 2 and frame 1, and reinforcing ribs are sewn between the two to achieve the initial constraint of filter cloth 2.

[0035] The filter cloth 2 has a binding strap 22 inside, and both ends of the binding strap 22 are sewn onto the filter cloth 2, so that an axial slot is formed between the binding strap 22 and the filter cloth 2; at the same time, a positioning plug 3 is added to the skeleton 1, which can be inserted into the slot, thereby further restricting the filter cloth 2 and making the filter cloth 2 more stable.

[0036] The binding strap 22 is elastic, that is, it has a certain degree of extensibility. When the filter cloth 2 shakes due to wind, it can buffer the vibration generated, reduce the damage to the cotton thread used in the binding strap 22, and extend its service life.

[0037] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The frame 1 includes a mounting ring 11. One end of the mounting ring 11 is fixed with multiple axially arranged and annularly distributed positioning rods 12. Multiple reinforcing ring seats 13 are fixed on the positioning rods 12. The multiple positioning rods 12 and the multiple reinforcing ring seats 13 together form a cylindrical frame.

[0038] Among them, an assembly ring 21 is fixed at one end of the filter cloth 2, and the assembly ring 21 is fixed on the cylinder frame;

[0039] Meanwhile, the reinforcing ring seat 13 includes an inner ring plate 131. The outer circumference of the inner ring plate 131 has sockets 132 corresponding to the position and number of positioning rods 12. The positioning rods 12 pass through the sockets 132 and are fixed by welding.

[0040] It should be noted that: for the frame 1, its mounting ring 11 can be fixed to the carrier equipment. It has multiple positioning rods 12 on one side, all of which are axially arranged, forming a cylindrical frame with the reinforcing ring seat 13. The filter cloth 2 is covered on the outside of the cylindrical frame. At the same time, an assembly ring 21 is also provided at one end of the filter cloth 2. The assembly ring 21 can be fixed to the cylindrical frame by bolts, thereby realizing the installation of the filter cloth 2.

[0041] The reinforcing ring seat 13 has an inner ring plate 131, which can serve as the mounting base for the positioning plug 3. The outer circumference of the inner ring plate 131 has a socket 132, and the positioning rod 12 can pass through the socket 132 and be fixed by welding, so that the positioning rod 12 is stably connected to the reinforcing ring seat 13.

[0042] In the embodiments of this utility model, please refer to Figure 3The positioning plug-in 3 includes a mounting base 31, which is welded and fixed to the outer circumference of the inner ring plate 131. A connecting rod 32 is welded and fixed to one side of the mounting base 31, and a spherical end 33 is welded and fixed to the other end of the connecting rod 32. The diameter of the spherical end 33 is larger than the diameter of the connecting rod 32.

[0043] The connecting rod 32 can be inserted into the slot formed between the strap 22 and the filter cloth 2;

[0044] Each inner ring plate 131 has two sets of positioning plugs 3, and the two sets of positioning plugs 3 on any two inner ring plates 131 are staggered.

[0045] It should be noted that in the positioning plug 3, the connecting rod 32 and the ball end 33 together form a plug structure, which can be inserted into the slot formed between the strap 22 and the filter cloth 2, thereby limiting the filter cloth 2;

[0046] In this configuration, each reinforcing ring seat 13 has two positioning plugs 3. It is necessary to ensure that the positioning plugs 3 on any two reinforcing ring seats 13 are in a misaligned state. Therefore, when the filter cloth 2 is put on the outside of the frame 1, each positioning plug 3 has a corresponding strap 22, which makes the installation more convenient.

[0047] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0048] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
