Description

Technical Field

[0001] The utility model relates to the field of roasting furnaces, in particular to a sliding smoke exhaust frame, which uses a blower fan to provide corresponding negative pressure to the combustion control system through the smoke exhaust frame to ensure production. Background Art

[0002] The smoke exhaust frame provides negative pressure to the corresponding flue through a branch pipe. The existing branch pipe is a fixed metal bellows branch pipe, which can only be slightly adjusted. When the end wall of the flue seriously deforms and displaces, accurate docking cannot be carried out. It is necessary to manually pull the branch pipe in the deformation direction and assist with iron plates, asbestos, sealing cloth, etc. for sealing, resulting in unstable negative pressure operation of the roasting system. It is difficult to accurately adjust the system negative pressure. In addition, due to serious deformation of the branch pipe and the end wall opening, a large amount of labor is required to adjust the branch pipe. After moving the sliding smoke exhaust frame, it takes at least 30 minutes to seal the smoke exhaust frame, affecting the temperature rise of the roasting system, thereby increasing the consumption of natural gas. Content of the Utility Model

[0003] The purpose of the utility model is to design the branch pipe of the sliding smoke exhaust frame to be able to freely slide the branch pipe of the smoke exhaust frame to both sides, so that the branch pipe of the smoke exhaust frame can freely slide and adjust to align with the transverse wall opening, reducing labor loss, ensuring system negative pressure, improving product quality, and reducing gas unit consumption.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a sliding smoke exhaust frame, including a sliding chute installed below the pipeline. Slide plates are installed on both sides of the bottom of the pipeline. A plurality of sliding bearings are provided on both sides of the sliding chute, and the sliding chute is installed on the slide plate through the sliding bearings; a sealing cotton is provided on the upper surface of the sliding chute to seal between the sliding chute and the pipeline;

[0005] At least one branch pipe is provided at the bottom of the sliding chute;

[0006] An opening is provided at the bottom of the pipeline, and a sliding telescopic chute is installed on the opening;

[0007] A gear shaft is installed below the slide plate, and a gear is installed on the gear shaft;

[0008] A rack meshing with the gear is provided at the bottom of the sliding chute;

[0009] Both ends of the gear shaft are installed on the first bearing seat;

[0010] One end of the gear shaft is fixedly connected to a handwheel. By rotating the handwheel, the gear shaft drives the gear to rotate, and then drives the sliding chute to move along the slide plate through the rack.

[0011] Further, the first bearing seat is connected to the slide plate through a hanging plate.

[0012] Further, the slide plate is connected to the pipeline through a channel steel.

[0013] Further, the rack is installed at the bottom of the sliding chute through a rack pipe support.

[0014] Further, the first bearing block is connected to the hanging plate through a rib plate.

[0015] Further, the sliding bearing is connected to the sliding chute through an adjusting bearing block.

[0016] Further, reinforcing rib plates are provided around the opening.

[0017] Further, longitudinal connecting angle steels are provided at the bottom of the sliding chute.

[0018] Further, a limiting plate is provided at one end of the slide plate.

[0019] Compared with the prior art, the advantages of the present utility model are as follows: It solves the problem that it is difficult to ensure the negative pressure among many problems caused by the deformation of the furnace body during the long-term use of the roasting furnace.

[0020] After experiments, the effect is very obvious. Among them, the sealing time of a single branch pipe and the end wall opening is reduced from 5 minutes in the past to 1 minute, greatly saving labor. The negative pressure of the system increases by 10 - 15 Pa at the same position, the temperature chasing time of each cycle of the system is reduced by about 30 minutes, and the initial temperature of a single flue in the heating area of the system increases by about 8 - 12 degrees.
