Description

Technical Field

[0001] The utility model belongs to the technical field of desulfurization tower construction, and specifically relates to anti-corrosion material painting equipment in a desulfurization tower. Background Art

[0002] In order to prevent the base material of the desulfurization tower from being corroded by water vapor and chemical solvents, multiple layers of anti-corrosion coatings need to be applied inside the desulfurization tower.

[0003] At present, anti-corrosion paint is usually applied manually. Due to the high height of the desulfurization tower, it is necessary to set up a climbing frame inside the desulfurization tower in advance to assist the staff in applying the anti-corrosion paint. However, the opening area at the bottom of the desulfurization tower is limited, and a large amount of climbing frame construction materials cannot be transported to the desulfurization tower at one time, resulting in a long construction time for the climbing frame, affecting the completion period of the desulfurization tower. At the same time, in order to ensure the structural stability of the climbing frame, the structure of the climbing frame is also relatively complex, and the anti-corrosion paint needs to be applied in multiple layers. It is also difficult for workers to repeatedly climb on the climbing frame with a complex structure, affecting construction efficiency. Utility Model Content

When applying the anti-corrosion paint, the staff only needs to place the equipment in the desulfurization tower in advance. The anti-corrosion material coating equipment moves up and down and sprays the paint with the help of a driving mechanism. The staff does not need to apply the paint manually or climb up and down, which greatly shortens the construction period.

[0005] The specific technical solution adopted by the utility model is:

[0006] The anti-corrosion material coating equipment in the desulfurization tower includes a frame and a storage tank fixedly connected to the frame, and is further provided with a spraying mechanism and a driving mechanism. The spraying mechanism is fixed on the frame, and the spraying mechanism includes a spray gun and a rotating motor.

DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0018] Specific embodiments, such as Figure 1-2 As shown, the utility model provides an anti-corrosion material coating device in a desulfurization tower, including a frame 2 and a storage tank 3 fixedly connected to the frame 2, and a spraying mechanism and a driving mechanism are additionally provided. The spraying mechanism is fixed on the frame 2, and the spraying mechanism includes a spray gun 4 and a rotating motor 5. The input end of the spray gun 4 is connected to the storage tank 3, and the output end of the spray gun 4 forms a circular motion with the center of the desulfurization tower 1 as the axis with the help of the rotating motor 5. The frame 2 has the freedom to move back and forth up and down along the inner wall of the desulfurization tower 1 with the help of the driving mechanism, and the paint in the storage tank 3 is sprayed on the inner wall of the desulfurization tower 1 with the help of the spraying mechanism and the driving mechanism.

[0019] At present, the anti-corrosion paint is usually applied manually on the inner wall of the desulfurization tower 1, and a climbing frame needs to be set up inside the desulfurization tower 1 in advance to assist the workers in applying the anti-corrosion paint. The construction time of the climbing frame is long, and it is difficult for the workers to climb repeatedly on the climbing frame, which affects the construction efficiency.

[0020] Therefore, the utility model provides an anti-corrosion material painting device. When applying the anti-corrosion paint, the staff only needs to place the device in the desulfurization tower 1 in advance, without the need for the staff to apply the paint manually and climb up and down, which greatly shortens the construction period. When in use, the device is placed in the desulfurization tower 1 and the anti-corrosion paint is added to the storage tank 3, and then the driving motor 6, the rotating motor 5 and the feeding pump at the input end of the spray gun 4 are started. The spray gun 4 will spray the paint on the inner wall of the desulfurization tower 1 under the action of the feeding pump. The rotating motor 5 can make the spray gun 4 rotate at a constant speed and spray the paint on the inner wall of the desulfurization tower 1. The driving mechanism can make the spray gun 4 rise at a constant speed and spray the paint evenly on the inner wall of the desulfurization tower 1.

[0021] The driving mechanism is located at the top of the desulfurization tower 1, and the driving mechanism includes a driving motor 6, a lifting rope 7 and a rotating shaft 8 suspended at the top of the desulfurization tower 1. One end of the lifting rope 7 is wound and fixed with the rotating shaft 8, and the other end of the lifting rope 7 is fixedly connected to the frame 2. The fixed end of the driving motor 6 is fixedly connected to the top of the desulfurization tower 1, and the output end of the driving motor 6 is fixedly connected to the rotating shaft 8. The lifting rope 7 has the freedom of winding with the help of the driving motor 6, and the frame 2 has the freedom of reciprocating up and down with the help of the retraction and extension of the lifting rope 7. The driving mechanism in the utility model suspends the frame 2 with the help of the lifting rope 7 and drives the frame 2 to reciprocate up and down. When the anti-corrosion material coating equipment needs to rise, the staff starts the driving motor 6 and makes it rotate forward. The lifting rope 7 will continuously wrap around the rotating shaft 8 to shorten the distance of the lifting rope 7 between the rotating shaft 8 and the frame 2, thereby realizing the rise of the anti-corrosion material coating equipment. When the anti-corrosion material coating equipment needs to descend, the staff can reverse the driving motor 6.

[0022] The spraying mechanism also includes a connecting beam 9, the fixed end of the rotating motor 5 is fixedly connected to the frame 2, the output end of the rotating motor 5 is fixedly connected to the middle part of the connecting beam 9, the spray gun 4 is symmetrically arranged at both ends of the connecting beam 9, and the storage tank 3 is fixed on the connecting beam 9. The utility model is provided with two groups of symmetrically arranged spray guns 4, so that the paint is applied more evenly and the paint efficiency is increased. At the same time, the spray gun 4 will generate a reaction force when spraying. The symmetrical arrangement of the spray gun 4 can prevent the reaction force from causing the anti-corrosion material painting equipment to tilt to one side.

[0023] At the same time, in order to prevent the suspension rope 7 from being entangled during the rotation of the connecting beam 9, a rotating bearing is provided in the middle of the connecting beam 9 in the utility model, and the suspension rope 7 is connected to the connecting beam 9 by means of the rotating bearing to prevent the suspension rope 7 from being entangled during the rotation of the connecting beam 9.

[0024] A stabilizing mechanism is also fixed below the frame 2. The stabilizing mechanism includes an articulated rod 10 and a running wheel 11 symmetrically arranged on both sides of the frame 2. The articulated rod 10 is hinged to the side wall of the frame 2. The running wheel 11 is symmetrically arranged at both ends of the articulated rod 10. The running wheels 11 on both sides of the articulated rod 10 are respectively in contact with the inner wall of the desulfurization tower 1. The running wheel 11 has the freedom to roll along the up and down direction of the desulfurization tower 1. The surface of the running wheel 11 is provided with anti-skid rubber. In order to prevent the anti-corrosion material brushing equipment from shaking when moving up and down, the utility model is also provided with a stabilizing mechanism, which forms a support through the articulated rod 10 and the running wheels 11 on both sides. When the anti-corrosion material brushing equipment moves, the articulated rod 10 and the running wheel 11 support both sides to form a limit, thereby preventing the anti-corrosion material brushing equipment from deviating and shaking to one side. In addition, the anti-skid rubber arranged on the surface of the running wheel 11 can increase the friction between the running wheel 11 and the inner wall of the desulfurization tower 1, so as to ensure that the anti-corrosion material brushing equipment is more stable during movement.

[0025] The articulated rods 10 are provided with two groups, and the two groups of articulated rods 10 are in an x-shape and are hinged to each other. An adjusting spring 12 is provided at the gap between the two groups of articulated rods 10 at the top, and the two groups of articulated rods 10 have the freedom to swing synchronously with the help of the adjusting spring 12. Since the desulfurization tower 1 may be a conical structure that is narrow at the top and wide at the bottom, if the distance between the running wheels 11 on both sides of the articulated rod 10 is fixed, it will cause the anti-corrosion material coating equipment to get stuck during the ascent process. Therefore, two groups of hinged articulated rods 10 are provided, and the two groups of articulated rods 10 are in a scissor shape and are provided with an adjusting spring 12. When the desulfurization tower 1 is wider, the upper openings of the two groups of articulated rods 10 will open under the action of the adjusting spring 12. At this time, the distance between the running wheels 11 on both sides of the articulated rod 10 is larger. When the desulfurization tower 1 is narrow, the inner wall of the desulfurization tower 1 will be squeezed. When the articulated rod 10 is pressed, the upper openings of the two groups of articulated rods 10 will shrink. At this time, the distance between the running wheels 11 on both sides of the articulated rod 10 is smaller, and the adjusting spring 12 is shortened under the action of the extrusion force. However, since the adjusting spring 12 has the rebound characteristic, the adjusting spring 12 will give the running wheel 11 a force toward the inner wall of the desulfurization tower 1, thereby ensuring that the running wheel 11 continues to be close to the inner wall of the desulfurization tower 1, and the entire stabilizing mechanism is still in a balanced state, avoiding shaking during the movement of the anti-corrosion material coating equipment and improving the spraying quality of the anti-corrosion coating.

[0026] The articulated rod 10 is a hollow tubular structure, and a plurality of groups of fixing holes 13 are arranged on the surface of the articulated rod 10 at intervals along the length direction. The walking wheel 11 is fixedly connected with a fixing rod 14, and a through hole matching the fixing hole 13 is arranged on the fixing rod 14. The fixing rod 14 is inserted into the hollow tube of the articulated rod 10 and is fixed by means of a fixing bolt 15 passing through the fixing hole 13 and the through hole. The distance between the walking wheel 11 and the end of the articulated rod 10 is adjustable by means of the fixing bolt 15. Since different desulfurization towers 1 have different diameters, in order to match the distance between the walking wheels 11 on both sides with the inner diameter of different types of desulfurization towers 1, the walking wheel 11 in the utility model is adjustable and fixedly connected to the articulated rod 10 by means of the fixing bolt 15. By matching the fixing bolt 15 with the fixing holes 13 at different positions, the distance between the walking wheel 11 and the end of the articulated rod 10 can be adjusted.
