Description

Technical Field

[0001] This utility model belongs to the field of flue gas conveying technology, and in particular relates to an adjustable flow flue gas conveying pipeline. Background Technology

[0002] Flue gas pipelines are key facilities used in industrial production for the safe transport of high-temperature and corrosive flue gases. They are mainly used to collect and transport flue gases generated during industrial processes, such as waste gases produced by combustion or chemical reactions in industries like thermal power generation, metallurgy, and chemicals.

[0003] In the prior art, such as patent CN217585365U, a flue gas collection and conveying pipeline for a submerged arc furnace is disclosed. This technical solution involves inserting the two ends of a sealing ring into the first and second annular grooves respectively. The inner and outer sealing rings are sealed and connected to the inner and outer walls of the first annular groove, avoiding direct action of high temperature and extending the sealing effect. Furthermore, when the sealing ring is inserted into the first and second annular grooves, the spring is compressed, and the pressure generated ensures that the sealing ring remains within the first and second annular grooves, resulting in a more secure connection and better sealing.

[0004] However, this flue gas conveying pipeline does not have the function of flue gas flow regulation during use, so it cannot dynamically adjust the flue gas volume. In addition, the installation direction is fixed and cannot be adjusted, and the installation and splicing operation is also inconvenient. Therefore, it still needs to be improved.

[0006] The control mechanism includes a valve disc, a valve core, a connecting seat, a motor, and a drive shaft. The valve disc is radially positioned in the middle of the inner cavity of the delivery pipe. The valve core is rotatably positioned within the inner cavity of the valve disc. The connecting seat is located at the top of the delivery pipe. The motor is located at the top of the connecting seat. One end of the drive shaft is connected to the main shaft of the motor, and the other end passes through the connecting seat, the delivery pipe, and the valve disc before connecting to the valve core.
