[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0026] like Figure 1The demister blade includes a blade body 1 and a secondary piece 2. The blade body 1 is convex in the middle. The secondary piece 2 is connected to the blade body 1. The blade body 1 includes a middle part 3. Both sides of the middle part 3 are connected to side parts 4. The cross-sections of the middle part 3 and the side parts 4 are both arc-shaped. One end of the secondary piece 2 is connected to the connection between the middle part 3 and one of the side parts 4. The other end of the secondary piece 2 is at a certain distance from the blade body 1 so that a gap is left between the secondary piece 2 and the middle part 3. The secondary piece 2 is added to the blade body 1, and the gap formed between the blade body 1 and the secondary piece 2 can also capture the mist, thereby greatly improving the demisting efficiency.

[0027] like Figure 2-Figure 9 As shown, a production device for demister blades includes an extrusion mechanism 5, a cooling mechanism 6, a conveying mechanism 7 and a cutting mechanism 8. The cutting mechanism 8 includes a frame 30. A guide rail 33 is provided at the upper end of the frame 30. A moving block 34 is slidably provided on the guide rail 33. Two supporting seats 35 are provided on the moving block 34. The upper end surface of the supporting seat 35 can be fitted with the lower end surface of the blade body 1 to effectively support the blade body 1. A support block 36 is provided on the moving block 34 at a position corresponding to the front side of the support seat 35. The end of the support block 36 can extend to the top of the support seat 35. The moving block 34 is connected to a mounting frame 43. A hydraulic cylinder 44 is provided on the upper part of the mounting frame 43. A lifting plate 45 is connected to the lower end of the piston rod of the hydraulic cylinder 44. A cutting knife 46 and a positioning rod 49 are connected to the lower part of the lifting plate 45. A gap is left between the two support seats 35 for the cutting knife 46 to pass through. A positioning seat 47 is connected to the rear side of the moving block 34. A through hole 48 is provided in the positioning seat 47. The through hole 48 passes through the positioning seat 47 from top to bottom. The positioning seat 47 is provided with a mounting seat 51, a mounting groove 52 is provided in the mounting seat 51, a trigger block 54 is slidably provided in the mounting groove 52, a part of the trigger block 54 extends into the through hole 48, abutting inclined surface 50 is provided at the lower end of the positioning rod 49, a guiding inclined surface 55 is provided at the upper end of the trigger block 54, the inclination direction of the abutting inclined surface 50 and the guiding inclined surface 55 are consistent, a spring 4 56 is connected to the end of the trigger block 54 away from the positioning seat 47, the other end of the spring 4 56 is connected to the side wall of the mounting groove 52, and a trigger 53 is installed on the side wall of the mounting groove 52 connected to the spring 4 56. Support plates 2 31 are provided on both the left and right sides of the frame 30, and a limiting groove 32 is provided on the right support plate 2 31.

[0028] Since there is only one connection between the auxiliary piece 2 and the blade body 1, the connection is not strong, and the cutting knife 46 can easily break the auxiliary piece 2 or cause the auxiliary piece 2 to break at the connection with the blade body 1. The blade passes through the limit groove 32 on the support plate 31 and reaches the moving block 34. The blade is positioned by the limit groove 32 so that the blade position is correct. The blade is supported by the support seat 35, and the end of the support block 36 can be inserted between the blade body 1 and the auxiliary piece 2. The auxiliary piece 2 is supported by the end of the support block 36, which can prevent the auxiliary piece 2 from being broken when the cutting knife 46 cuts.

[0029] On the other hand, if the cutting knife 46 descends too fast, it is easy to break the secondary sheet 2, so it is necessary to reduce the descending speed of the cutting knife 46. Since the blades are transported forward all the time, reducing the cutting speed of the cutting knife 46 requires that the cutting knife 46 can move with the blades, otherwise the blades and the cutting knife 46 will be subjected to a force perpendicular to the cutting direction, causing damage to both. When cutting the blades, the hydraulic cylinder 44 drives the lifting plate 45 to descend, and the lifting plate 45 drives the positioning rod 49 and the cutting knife 46 to move downward. The positioning rod 49 is first inserted into the through hole 48 of the positioning seat 47, and the abutting inclined surface 50 at the lower end of the positioning rod 49 abuts against the guiding inclined surface 55 at the upper end of the trigger block 54. As the positioning rod 49 descends, the trigger block 54 is pushed into the mounting groove 52, so that the trigger block 54 contacts the trigger 53. When the triggers 53 on the two support seats 35 are triggered, it indicates that the two positioning rods 49 are inserted into the corresponding positioning seats 47, that is, the cutting knife 46 is correspondingly located above the gap between the two support seats 35. At this time, the hydraulic cylinder 44 drives the lifting plate 45 to continue to move downward. The cutting knife 46 descends to cut the auxiliary piece 2. At this time, the cutting knife 46 contacts the blade section, and the movement of the blade will act on the cutting knife 46. Since the positioning rod 49 is inserted into the positioning seat 47, the force acting on the cutting knife 46 will drive the moving block 34 to move, so that the cutting knife 46 can move with the blade. In the process of the cutting knife 46 cutting the blade, the two move synchronously to ensure that the cutting knife 46 can cut the blade normally. The transmission is realized by the cooperation of the positioning rod 49 and the positioning seat 47, which can reduce the force acting on the piston rod of the hydraulic cylinder 44, prevent the movable rod from being deflected by the force perpendicular to its extension direction, and prevent the subsequent piston rod from being unable to drive the lifting plate 45 to lift vertically.

[0030] When only one trigger 53 is triggered, it indicates that the cutting blade 46 is misaligned with the moving block 34, and the hydraulic cylinder 44 controls the lifting plate 45 to rise back to the original position, and reminds the staff to check at the same time.

[0031] The left end of the guide rail 33 is connected to a mounting block 37, the left end of the moving block 34 is connected to a connecting block 38, and a spring 2 39 is connected between the connecting block 38 and the mounting block 37. Through the setting of the spring 2 39, after the moving block 34 is driven to move, when the cutting knife 46 rises and separates from the blade after cutting is completed, the moving block 34 can be reset.

[0032] The right end of the guide rail 33 is connected to the second mounting block 40, the left end of the second mounting block 40 is connected to the third spring 42, and the left end of the third spring 42 is connected to the buffer block 41. During the resetting process of the moving block 34, the buffer block 41 and the third spring 42 play a buffering role to decelerate the moving block 34. At the same time, the second spring 39 and the third spring 42 play a balancing role, so that the initial position of the moving block 34 is relatively fixed.

[0033] The cooling mechanism 6 includes a cooling block 9 and a cooling box 10 connected to each other. A plurality of support plates 16 are arranged in the cooling box 10. The upper end surface shape of the support plates 16 matches the lower end surface shape of the blade body 1, so as to better support the passing blades. A water outlet plate 11 is arranged on the upper part of the cooling box 10. The cooling block 9 and the water outlet plate 11 are both provided with a water inlet pipe, which is connected to an external water supply mechanism. The water outlet plate 11 discharges water downwards to spray the blades passing thereunder to cool the blades.

[0034] The cooling block 9 is provided with a channel 17, the shape of which is the same as that of the blades. The channel 17 is arranged through the cooling block 9, and a plurality of cooling holes 18 are arranged on the periphery of the channel 17. One end of the cooling hole 18 is connected to the side of the cooling block 9, and the other end of the cooling hole 18 is connected to the water inlet pipe. Water flows through the cooling hole 18 to reduce the overall temperature of the cooling block 9, and cool the blades passing through the channel 17. The cooling holes 18 are arranged around the periphery of the channel 17, so that the cooling source is close to the blades passing through the channel 17, and the blades can be cooled better. The water passing through the cooling holes 18 flows into the cooling box 10.

[0035] The cooling mechanism 6 also includes a water receiving tray 12. The end of the cooling box 10 away from the cooling block 9 is located above the water receiving tray 12. The water flowing out of the cooling box 10 can fall into the water receiving tray 12 for collection. The collected water can continue to be used after being cooled.

[0036] A support plate 13 is provided in the water receiving tray 12. An air supply pipe 14 is provided at one end of the water receiving tray 12 away from the cooling box 10. A plurality of air blowing pipes 15 are connected to the air supply pipe 14. The air blowing pipes 15 are arranged toward the support plate 13. The air supply pipes 14 are connected to an external air pump. When the blades leave the cooling box 10 and reach the top of the water receiving tray 12, the water remaining on the blades can drip into the water receiving tray 12. At the same time, the air blowing pipes 15 can blow compressed gas toward the blades, thereby blowing water off the blades as much as possible.

[0037] The conveying mechanism 7 includes a base 19, and the front and rear sides of the upper part of the base 19 are connected to side plates 21, and a support sheet 20 is connected between the two side plates 21. A support rod 22 is connected to the inner side of the side plate 21, and a rotating arm 26 is installed on the support rod 22. A pressure wheel 24 is rotatably arranged on the rotating arm 26. A driving motor 28 is installed on one of the side plates 21, and the driving motor 28 is driven and connected to a driving wheel 29. The driving motor 28 is installed on the side plate 21 through a lifting mechanism 27, and the lifting mechanism 27 drives the driving motor 28 to rise and fall, thereby adjusting the height of the driving wheel 29, so that the driving wheel 29 can resist the upper end surface of the blade, thereby driving the blade to move. The pressure wheel 24 can press on the upper end surface of the blade and rotate to limit the blade.

[0038] The rotating arm 26 is rotatably arranged on the support rod 22, the rotating arm 26 is connected with a connecting rod 25, the connecting rod 25 is connected with a spring 1 23, and the other end of the spring 1 23 is connected to the support rod 22. Through the arrangement of the spring 1 23, the elastic force of the spring 1 23 enables the rotating arm 26 to have a downward movement force, and the pressure wheel 24 can better press on the upper end surface of the blade to limit the position.

[0039] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
