Abstract
Description
Technical Field
[0001] This utility model relates to the field of boiler equipment technology, specifically a silencer for boilers. Background Technology
[0002] The silencer used in boilers takes high-temperature and high-pressure steam and low-pressure steam, which are first expanded and depressurized inside the silencer, and then enter the secondary depressurization body. After being expanded and depressurized in a large volume to form low-pressure or ultra-low-pressure steam, it is then sprayed out and then passes through a combined multi-material composite sound-absorbing cover outside the depressurization body for further sound absorption before being discharged into the atmosphere.
[0003] Boilers generate a lot of noise during operation, requiring the installation of silencers to reduce noise. Since silencers need to be connected to the outside environment, dust from the outside air can easily enter the boiler through the silencer when it is not in use. This not only affects the boiler's combustion efficiency but also causes blockages as dust can easily enter the silencer. Existing silencers have a switch door, which is closed when not in use to isolate the silencer from the boiler and prevent dust from entering. However, since the silencer is very hot after use, manually closing the switch door can easily cause burns. Therefore, a new type of silencer for boilers is proposed. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-3 This utility model provides a new technical solution: a boiler silencer, including a boiler silencer body 1, two fixing blocks 2 are fixedly installed on the outer surface of the boiler silencer body 1, and a rotating shaft 3 is fixedly installed on the inner wall of the two fixing blocks 2.
[0029] The boiler silencer body 1 is equipped with a dustproof mechanism, which includes two first fixing plates 4, a door panel 5, a support rod 6, a fixing column 7, a support rod 8, a motor 9, a partition 10, multiple baffles 11, a ventilation slot 12, a slide 13, multiple fixing rods 14, multiple second fixing plates 15, multiple second fixing rods 16, a vertical plate 17, a hydraulic rod 18, and a hydraulic device 19.
[0030] Furthermore, the two first fixing plates 4 rotate on the outer surfaces of the two rotating shafts 3 respectively, and the two door panels 5 are fixedly installed on the opposite sides of the two first fixing plates 4;
[0031] Two support rods 6 are rotatably connected to the rear surfaces of the two door panels 5.
[0032] Furthermore, the fixed column 7 is rotatably connected to the rear end of the two support rods 6, and the support rod 8 is fixedly connected to the outer surface of the fixed column 7;
[0033] Among them, the motor 9 is fixedly installed on the outer surface of the boiler silencer body 1, and the output shaft of the motor 9 is fixedly sleeved on the inner surface of the support rod 8.
[0034] Furthermore, the baffle 10 is fixedly installed on the inner surface of the boiler silencer body 1, and a ventilation groove 12 and a sliding groove 13 are provided on the rear surface of the baffle 10.
[0035] The left ends of multiple fixing rods 14 are rotatably connected to the inner wall of the ventilation slot 12, the right ends of multiple fixing rods 14 penetrate into the slide 13, and the baffle 11 is fixedly sleeved on the outer surface of multiple fixing rods 14.
[0036] Furthermore, multiple second fixing plates 15 are rotatably sleeved on the outer surface of the fixing rod 14, and a second fixing rod 16 is rotatably sleeved on the outer surface of the multiple fixing rods 14;
[0037] The upright plate 17 is fixedly installed on the right end of multiple second fixed rods 16.
[0038] Furthermore, the hydraulic rod 18 is fixedly installed on the upper end of the vertical plate 17, and the hydraulic device 19 is slidably sleeved on the outer surface of the hydraulic rod 18. The hydraulic device 19 is fixedly installed on the outer surface of the boiler silencer body 1.
[0039] When using this boiler silencer, starting the motor 9 causes it to output power to the support rod 8, which is fixedly mounted on the outer surface of the output shaft, causing it to move in a circular motion. Simultaneously, the support rod 8 pulls the fixed column 7 at its upper end to move to the right. This movement of the fixed column 7 also drives the two support rods 6, which are rotatably mounted on its outer surface, to move to the right. As the two support rods 6 move to the right, they gradually become vertical, simultaneously applying a rightward thrust to the two door panels 5 rotatably connected to their right ends. The two door panels 5, via the first fixed plate 4 fixedly mounted on opposite sides, rotate on the outer surface of the rotating shaft 3 and gradually move horizontally, completing the opening and closing of the door panels 5. When adjusting the air intake of the silencer, the... By starting the hydraulic device 19, the hydraulic device 19 drives the hydraulic rod 18, which is slidably sleeved on the inner surface, to move upward. The hydraulic rod 18 drives the vertical plate 17, which is fixedly installed at the lower end, to move upward. The vertical plate 17 drives the multiple second fixed rods 16, which are fixedly installed on the left surface, to move upward. While the multiple second fixed rods 16 are moving upward, they drive the multiple second fixed plates 15, which are rotatably sleeved on the outer surface, to move upward. While the second fixed plates 15 are moving, they drive the fixed rods 14, which are fixedly sleeved on the inner surface, to rotate. At the same time, the fixed rods 14 drive the baffles 11, which are fixedly sleeved on the outer surface, to rotate. The baffles 11 gradually become vertical. At this time, the angle of the baffles 11 can be adjusted to control the amount of air entering the ventilation slot 12.
[0040] This boiler silencer can automatically open and close by rotating two door panels on a shaft via a motor. This allows for opening and closing even when the silencer is still hot after use, preventing burns from manual operation and facilitating its use. Furthermore, the silencer allows for control of the airflow by adjusting the angle of the baffles within the ventilation slots. By controlling the airflow, dust can be further treated by the internal dust collector, a common feature in silencers, which is not specifically mentioned in this invention. This design further prevents dust from entering the silencer, making it more convenient.
[0041] Working Principle: When using this boiler silencer, starting the motor 9 outputs power to the support rod 8 fixedly mounted on the outer surface of the output shaft, causing it to move in a circular motion. Simultaneously, the support rod 8 pulls the fixed column 7 at the upper end to move to the right. This movement of the fixed column 7 also drives the two support rods 6, which are rotatably mounted on the outer surface, to move to the right. As the two support rods 6 move to the right, they gradually become vertical. At the same time, the two support rods 6 exert a rightward thrust on the two door plates 5 rotatably connected to the right end. The two door plates 5, through the first fixed plate 4 fixedly mounted on opposite sides, rotate on the outer surface of the rotating shaft 3 and gradually move horizontally, completing the opening and closing of the door plates 5. This adjusts the air intake of the silencer. When the hydraulic device 19 is activated, the hydraulic device 19 drives the hydraulic rod 18, which is slidably sleeved on the inner surface, to move upward. The hydraulic rod 18 drives the vertical plate 17, which is fixedly installed at the lower end, to move upward. The vertical plate 17 drives the multiple second fixed rods 16, which are fixedly installed on the left surface, to move upward. While the multiple second fixed rods 16 are moving upward, they drive the multiple second fixed plates 15, which are rotatably sleeved on the outer surface, to move upward. While the second fixed plates 15 are moving, they drive the fixed rods 14, which are fixedly sleeved on the inner surface, to rotate. At the same time, the fixed rods 14 drive the baffles 11, which are fixedly sleeved on the outer surface, to rotate. The baffles 11 gradually become vertical. At this time, the angle of the baffles 11 can be adjusted to control the amount of air entering the ventilation slot 12.
[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
