DETAILED DESCRIPTION

[0022] The following will be described in detail with reference to the accompanying drawings. Figure 1 - the accompanying drawings Figure 5 The present application will be further described in detail.

[0023] A demister, with reference to Figure 1 , Figure 2 and Figure 3, comprising a first connecting shaft 1, a second connecting shaft 2, a blade 3 and a fixing assembly 4, the first connecting shaft 1 is arranged above the second connecting shaft 2, the blade 3 is arranged between the first connecting shaft 1 and the second connecting shaft 2, the fixing assembly 4 is arranged between the upper end of the blade 3 and the first connecting shaft 1 and between the lower end of the blade 3 and the second connecting shaft 2, the upper end of the blade 3 is detachably connected to the first connecting shaft 1 through the fixing assembly 4, and the lower end of the blade 3 is detachably connected to the second connecting shaft 2 through the fixing assembly 4. The blade 3 is provided with a plurality of blades 3, and the mounting mode of the plurality of blades 3 is the same. When the blade 3 is replaced, only the restriction of the fixing assembly 4 on the blade 3 needs to be removed, so that the single blade 3 can be disassembled and replaced, thereby avoiding the replacement of the entire demister due to the damage of one blade 3, and the maintenance and replacement cost is reduced.

[0024] Further, the first connecting shaft 1 and the second connecting shaft 2 are each provided with a plurality of first connecting shafts 1 and a plurality of second connecting shafts 2, in this embodiment, the first connecting shaft 1 and the second connecting shaft 2 are provided with two first connecting shafts 1 and two second connecting shafts 2, the two first connecting shafts 1 are distributed on both sides of the upper end of the blade 3, and the two second connecting shafts 2 are distributed on both sides of the lower end of the blade 3, through the arrangement of the plurality of first connecting shafts 1 and the plurality of second connecting shafts 2, the stability of the blade 3 installation is further increased, and the possibility of blade 3 shaking is reduced.

[0025] Referring to Figure 3 , Figure 4 and Figure 5 , further, the fixing assembly 4 comprises a mounting block 41 and a fixing block 42, the mounting block 41 is fixed on the first connecting shaft 1 or the second connecting shaft 2, a sliding groove 411 is formed in the mounting block 41, and the fixing block 42 is slidably arranged on the mounting block 41. The inner wall of the sliding groove 411 is fixedly connected with an elastic block 5, and the elastic block 5 is used for limiting the sliding of the fixing block 42.

[0026] Specifically, when it is necessary to fix the blade 3, the fixing block 42 mounted on the first connecting shaft 1 slides downward until abutting against the blade 3, and the fixing block 42 mounted on the second connecting shaft 2 slides upward until abutting against the blade 3, when the fixing block 42 on the first connecting shaft 1 abuts against the blade 3, the fixing block 42 is abutted by the blade 3 and the lower surface of the elastic block 5, and when the fixing block 42 on the second connecting shaft 2 abuts against the blade 3, the fixing block 42 is abutted by the blade 3 and the upper surface of the elastic block 5. Since the width of the blade 3 is fixed and the distance between the two elastic blocks 5 is fixed, the blade 3 is clamped by the two fixing blocks 42, and the blade 3 is fixed.

[0027] When it is necessary to disassemble the blade 3, the fixing block 42 is moved away from the blade 3, so that the fixing block 42 is clamped by the inner wall of the sliding groove 411 and the elastic block 5, at this time, the distance between the two fixing blocks 42 is greater than the width of the blade 3, so that the blade 3 is released from the limitation, and the blade 3 can be disassembled and replaced.

[0028] Further, the elastic block 5 is provided with arc surfaces 51 at the upper end and the lower end. When the fixing block 42 slides, the elastic block 5 is more likely to be elastically deformed due to the guiding effect of the arc surfaces 51, which reduces the difficulty of sliding of the fixing block 42 and reduces the possibility of jamming.

[0029] Further, the fixing block 42 is provided with a first clamping groove 424. When the fixing block 42 moves towards the blade 3, the blade 3 is inserted into the first clamping groove 424 and is limited by the first clamping groove 424. When the blade 3 abuts against the inner bottom wall of the first clamping groove 424, the fixing block 42 abuts against the elastic block 5, thereby limiting the blade 3. Due to the provision of the first clamping groove 424, the installation stability of the blade 3 is further increased, and the shaking of the blade 3 is further reduced.

[0030] Specifically, the fixing block 42 comprises a first clamping plate 421, a second clamping plate 422 and a connecting rod 423. The connecting rod 423 is fixed at both ends of the first clamping plate 421 and the second clamping plate 422 and is slidably arranged in the sliding groove 411. The width of the first clamping plate 421 and the second clamping plate 422 is greater than the width of the sliding groove 411. That is, the side of the first clamping plate 421 close to the second clamping plate 422, the side of the second clamping plate 422 close to the first clamping plate 421 and the outer surface of the connecting rod 423 together form the first clamping groove 424. During the sliding of the connecting rod 423, the first clamping plate 421 and the second clamping plate 422 always clamp the mounting block 41 in the middle, thereby limiting the sliding path of the connecting rod 423 and reducing the possibility of deviation of the sliding direction of the connecting rod 423.

[0031] Further, the connecting rod 423 is in a cylindrical shape. When the connecting rod 423 abuts against the elastic block 5, the connecting rod 423 is more likely to slide on the elastic block 5 due to the cylindrical shape, thereby further facilitating the sliding of the fixing block 42 in the sliding groove 411 and reducing the possibility of jamming.

[0032] Further, the blade 3 is provided with a second clamping groove 31. A plurality of second clamping grooves 31 are provided, and the plurality of second clamping grooves 31 are arranged in one-to-one correspondence with the plurality of fixing blocks 42. When the connecting rod 423 slides into the second clamping groove 31, the first clamping plate 421 and the second clamping plate 422 clamp the blade 3 in the middle and the second clamping groove 31 limits the movement of the connecting rod 423, thereby further increasing the installation stability of the blade 3.

[0033] Further, the second clamping groove 31 is in shape adaptation with the connecting rod 423. Due to the shape adaptation of the second clamping groove 31 with the connecting rod 423, the contact area of the connecting rod 423 with the second clamping groove 31 is increased, and the possibility of horizontal sliding of the connecting rod 423 in the second clamping groove 31 is reduced, thereby further increasing the installation stability of the blade 3.

[0034] The embodiments of the present application are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, wherein the same parts are denoted by the same reference numerals. Therefore, any equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
