Description

Technical Field

[0001] This utility model relates to the field of combustion furnace technology, specifically a pneumatic chimney baffle with a self-cleaning structure. Background Technology

[0002] Pneumatic chimney dampers are installed on the boiler chimney. When the boiler is not running, the chimney damper can be closed, which greatly reduces the temperature drop inside the waste heat boiler, provides more energy for restarting the waste heat boiler, and reduces the boiler warm-up time.

[0003] In existing technologies, the bottom of pneumatic chimney dampers usually accumulates a lot of impurities. After long-term use, these impurities can easily cause the dampers to become clogged, making them difficult to open and close. However, cleaning requires manual cleaning by staff, resulting in a low degree of automation. Therefore, we have introduced a pneumatic chimney damper with a self-cleaning structure. Utility Model Content

[0004] The purpose of this invention is to provide a pneumatic chimney baffle with a self-cleaning structure, which can automatically clean the impurities adsorbed and accumulated at the bottom of the baffle, with a high degree of automation, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A pneumatic chimney baffle with a self-cleaning structure includes a chimney and a baffle. The chimney sidewall has a rectangular hole, and the baffle is slidably disposed within the rectangular hole. Both ends of the baffle extend outside the rectangular hole. A moving mechanism is provided on the outer side of the chimney at the upper side of the baffle. A housing is fixedly disposed on the outer side of the chimney at the lower side of the baffle. A motor is fixedly disposed on the lower inner wall of the housing. A strip-shaped hole is provided at the upper end of the housing. A vertical moving rod is slidably disposed within the strip-shaped hole. A cleaning brush is fixedly disposed at the upper end of the moving rod. A reciprocating mechanism is provided between the lower end of the moving rod and the motor.

[0006] As a further embodiment of this utility model, the moving mechanism includes a cylinder, which is fixedly mounted on the outer wall of the chimney, and a connecting block is fixedly mounted on the output end of the cylinder, with the lower end of the connecting block fixedly connected to a baffle.

[0007] As a further embodiment of this utility model, the reciprocating mechanism includes a turntable, which is fixedly mounted on the output end of a motor. A strip frame is provided on the upper side of the turntable, and a guide post is slidably mounted inside the strip frame. The lower end of the guide post is fixedly connected to the upper edge of the turntable. Sliding sleeves are provided at both ends of the strip frame, and sliding rods are slidably mounted inside the sliding sleeves. Both ends of the sliding rods are fixedly connected to the housing, and the lower end of the moving rod is fixedly connected to the strip frame.

[0008] As a further embodiment of this invention, a sealing ring is provided inside the rectangular hole.

[0009] As a further embodiment of this invention, the sealing ring is configured as a corrosion-resistant rubber ring.

[0010] As a further embodiment of this invention, the length of the strip frame is greater than the diameter of the turntable.

[0011] As a further embodiment of this invention, the cleaning brush is configured as a glass fiber brush.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This pneumatic chimney baffle with a self-cleaning structure, consisting of a chimney, cleaning brush, cylinder, baffle, moving rod, housing, motor, turntable, connecting block, sliding rod, sliding sleeve, guide column, and strip frame, automatically cleans the baffle when self-cleaning is required. The cylinder's piston rod pushes the connecting block, moving the portion of the baffle inside the chimney to the outside. Simultaneously, the motor starts, rotating the turntable, which in turn rotates the guide column. The guide column reciprocates within the strip frame, causing the strip frame to move left and right. The strip frame, via the moving rod, drives the cleaning brush to clean the accumulated impurities at the bottom of the baffle. This highly automated system automatically cleans the accumulated impurities at the bottom of the baffle. Attached Figure Description

[0017] 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.

[0018] Please see Figures 1 to 3 This utility model provides a technical solution: A pneumatic chimney baffle with a self-cleaning structure includes a chimney 1 and a baffle 4. The chimney 1 has a rectangular hole on its side wall. The baffle 4 is slidably disposed in the rectangular hole, and both ends of the baffle 4 extend to the outside of the rectangular hole. A moving mechanism is provided on the outer side of the chimney 1 above the baffle 4. A housing 6 is fixedly disposed on the outer side of the chimney 1 below the baffle 4. A motor 7 is fixedly disposed on the lower inner wall of the housing 6. The motor 7 is electrically connected to an external power supply through a control switch. A strip-shaped hole is provided at the upper end of the housing 6. A vertical moving rod 5 is slidably disposed in the strip-shaped hole. A cleaning brush 2 is fixedly disposed at the upper end of the moving rod 5. The cleaning brush 2 is made of glass fiber bristles to improve durability.
