[0042] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0044] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0045] like Figure 1 and Figure 2As shown, the electrostatic precipitator ceramic block assembly mainly includes a ceramic block 1, a connecting ring 2, a nut 3 and a clamp 6.

[0046] A limiting protrusion 7 is provided on the axial periphery of the ceramic block 1 , and the limiting protrusion 7 is a part of the ceramic block 1 .

[0047] A connecting ring 2 is sleeved on the ceramic block 1. The connecting ring 2 is sleeved on the outer periphery of the ceramic block 1 from one side of the ceramic block 1. The connecting ring 2 has a first end 8 and a second end 9. The first end 8 of the connecting ring 2 is pressed against one side of the limiting protrusion 7. The second end 9 of the connecting ring 2 is used to connect with the outer cylinder sealing plate 19 of the electrostatic precipitator, thereby indirectly fixing the ceramic block 1 on the outer cylinder sealing plate 19. The outer peripheral surface of the connecting ring 2 is provided with an external thread.

[0048] The nut 3 is sleeved on the outer circumference of the ceramic block 1 from the other side of the ceramic block 1. One end of the nut 3 is provided with an internal thread, which matches the external thread on the outer circumference of the connecting ring 2. This end passes over the limiting protrusion 7 and is combined with the external thread on the outer circumference of the connecting ring 2; the edge of the other end of the nut 3 extends radially inward to form a trimming edge 10 (see Figure 2 ), the edge 10 is tightly pressed against the other side of the limiting protrusion 7, that is, the edge 10 and the first end 8 on the connecting ring 2 clamp the limiting protrusion 7, so that the connecting ring 2 is fixed on the ceramic block 1, and the ceramic block 1 is fixed on the outer cylinder sealing plate 19 through the connection between the connecting ring 2 and the outer cylinder sealing plate 19.

[0049] In order to improve the sealing performance and prevent dust from entering the electrostatic precipitator through the gap between the first end 8 and the limiting protrusion 7, a sealing ring 12 is further provided between the first end 8 and the limiting protrusion 7. In order to place the sealing ring 12 more stably, a groove 13 is provided in the first end 8, and the sealing ring 12 is embedded in the groove 13.

[0050] A flange Ⅰ4 is welded on the nut 3, and a flange Ⅱ5 is sleeved on the outer periphery of the connecting ring 2. A keyway (not shown in the figure) is provided on the connecting ring 2, and a brake key 11 (see Figure 1 ), the brake key 11 is arranged corresponding to the keyway. When the flange II 5 is inserted into the outer periphery of the connecting ring 2, the brake key 11 is inserted into the keyway, so that relative rotation cannot occur between the flange II 5 and the connecting ring 2.

[0051] When the nut 3 and the connecting ring 2 clamp the limiting protrusion 7, the flange I4 and the flange II5 are close to each other, and the flange I4 and the flange II5 are connected together through the clamp 6.

[0052] like Figure 3 The hoop 6 includes two limiting pieces 14 (in other embodiments, the limiting pieces 14 may also have one, three, four or more pieces, and the number is not particularly limited) and a hoop 15. Figure 3In a, the stopper 14 is provided with an embedding groove 16, which is used to insert the outer edges of flange I4 and flange II5, thereby limiting the axial separation of flange I4 and flange II5. When the stopper 14 is inserted into the outer edges of flange I4 and flange II5, the hoop 15 is constrained on the outer periphery of the stopper 14, such as Figure 3 b. The cuff 15 has at least a released state and a tightened state, thereby facilitating disassembly.

[0053] When the clamp 6 connects flange I4 and flange II5 together, flange I4 and flange II5 are fixed together, and due to the action of the keyway and the brake key 11, flange II5 and the connecting ring 2 cannot rotate around the axis, and flange I4 is welded to the nut 3, so the nut 3 and the connecting ring 2 cannot rotate around the axis, that is, the nut 3 will not loosen, nor will it separate from the connecting ring 2, so that the ceramic block 1 is not easy to loosen and can be safely connected to the connecting ring 2, that is, the ceramic block 1 is safely connected to the outer cylinder sealing plate 19.

[0054] In order to better protect the ceramic block 1, a rain cover 17 is also provided to prevent rain from falling on the ceramic block 1 to avoid electrostatic precipitator failure. A flange III 18 is provided on the rain cover 17, and the flange III 18 is connected to the flange I4 and the flange II 5. The flange III 18 is also embedded in the embedding groove 16 of the limit plate 14 (see Figure 2 ), and thus fixed by the clamp 6. In this example, the rain cover 17 is connected to the connecting ring 2 and the nut 3 through the flange III 18, which can prevent the rain cover 17 from falling off due to vibration when the electrostatic precipitator is working and facilitate the removal of the rain cover 17. In other embodiments, the rain cover 17 can also have other connection methods, such as screwing the rain cover 17 on the outer periphery of the nut 3 (providing threads on the outer periphery of the nut 3), or welding the rain cover 17 to the nut 3.

[0055] In summary, in this example, a limiting protrusion 7 is provided on the ceramic block 1, and the limiting protrusion 7 is clamped by the combination of the connecting ring 2 and the nut 3, so that the ceramic block 1 is connected to the connecting ring 2, and then connected to the outer cylinder sealing plate 19. The nut 3 and the connecting ring 2 are combined together by threading. Due to the setting of the flange I4, the flange II5 and the clamp 6, it is not easy for the nut 3 to rotate with the connecting ring 2, that is, it is not easy for the nut 3 to loosen from the connecting ring 2, so that even if there is vibration when the electrostatic precipitator is working, the nut 3 is not easy to loosen, so that the ceramic block 1 is not easy to loosen, and finally the electrostatic precipitator has a more stable performance.

[0056] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
