Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of RTO combustion devices, specifically to an RTO combustion device with dynamic ratio of exhaust gas to oxygen. Background Technology
[0002] RTO (Regenerative Thermal Oxidizer) combustion units are the core equipment for treating industrial organic waste gas. They achieve complete combustion of waste gas through a dynamic "waste gas-oxygen" ratio. Existing RTO combustion units often use fixed welding or bolted connections to install their ductwork at the top or high up of the unit. These ducts transport waste gas containing dust and sticky organic matter for extended periods, leading to dust accumulation and coking on their inner walls, requiring regular cleaning. However, fixed ductwork at high locations necessitates scaffolding or the use of climbing equipment, making cleaning extremely time-consuming and labor-intensive, and posing safety risks associated with working at heights. Utility Model Content
[0003] In view of the problems existing in the above-mentioned RTO combustion device with dynamic ratio of exhaust gas and oxygen, this utility model is proposed.
[0004] Therefore, the purpose of this invention is to provide an RTO combustion device with dynamic ratio of exhaust gas to oxygen, which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: An RTO combustion device with dynamic ratio of exhaust gas to oxygen includes a base plate and a combustion device body. The combustion device body is fixedly mounted on the upper surface of the base plate. A connecting pipe is rotatably mounted on one side of the combustion device body. An air duct is connected to the end of the connecting pipe away from the combustion device body. The air duct is fixedly sleeved with the outer wall of the connecting pipe. A transmission mechanism for driving the connecting pipe to rotate is provided on the front side of the combustion device body. A limiting mechanism for restricting the rotation of the air duct is provided at the upper end of the combustion device body.
[0006] Preferably, the transmission mechanism includes a first bevel gear and a second bevel gear. The first bevel gear is fixedly sleeved on the outer wall of the connecting pipe. A transmission rod is rotatably arranged on the front side of the combustion device body and on one side of the connecting pipe. The second bevel gear is fixedly sleeved on the rod wall of the transmission rod. The first bevel gear and the second bevel gear are meshed together. A hydraulic cylinder is fixedly arranged on the upper surface of the base plate and on one side of the transmission rod. A lever is fixedly sleeved at the front end of the transmission rod. A strip-shaped opening is opened on the surface of the lever. A round pin is fixedly arranged on the front side of the piston rod end of the hydraulic cylinder. The front end of the round pin passes through the strip-shaped opening.
[0007] Preferably, the limiting mechanism includes a spur gear and a rack. Rotary rods are rotatably mounted at both ends of the upper part of the combustion device body, near the air duct. A baffle is fixedly sleeved on the rod wall of each rotating rod, and the baffles on both sides abut against the front and rear sides of the air duct. The spur gear is fixedly sleeved on one outer end of the rotating rod, and the rack is meshed on the upper side of the gear. A U-shaped plate is mounted above the combustion device body, and a horizontal plate is fixedly mounted on each of the two vertical ends of the U-shaped plate. The lower side of the horizontal plate is fixedly connected to the corresponding rack. Two side plates are fixedly mounted on the top of the combustion device body, and a lead screw is rotatably mounted between the two side plates. The middle end of the U-shaped plate is threadedly sleeved with the lead screw. A motor is fixedly mounted on the outer side of one side plate, and the output end of the motor is fixedly connected to one end of the lead screw.
[0008] Preferably, the front end of the round pin is fixedly sleeved with an anti-detachment ring.
[0009] Preferably, a slide bar is arranged parallel to the lower side of the lead screw, both ends of the slide bar are fixedly connected to the corresponding side plates, and the middle end of the U-shaped plate is movably sleeved with the slide bar.
[0010] Preferably, the rod wall of the round pin and the inner wall of the strip-shaped opening are both coated with a wear-resistant coating.
[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. In this utility model, the motor drives the lead screw to rotate, which causes the U-shaped plate to move. The U-shaped plate drives the rack to move, which causes the gear to rotate. This causes the rotating rod to drive the baffle to rotate to a vertical position, thus releasing the restriction on the air duct.
[0012] 2. In this utility model, the piston rod of the hydraulic cylinder retracts, causing the round pin to slide within the slot, which in turn drives the lever to rotate. The lever then drives the transmission rod to rotate, which in turn causes the second bevel gear to drive the first bevel gear to rotate. This causes the connecting pipe to rotate the air duct to a horizontal position, and the air duct to be lowered to a lower position, making it easier to maintain the inside of the air duct.

The rod wall of the round pin 19 and the inner wall of the strip-shaped opening are coated with a wear-resistant coating to improve the wear resistance of the round pin 19 and the inner wall of the strip-shaped opening.
[0020] Reference Figure 1-3The limiting mechanism includes a spur gear 11 and a rack 17. A rotating rod 10 is rotatably mounted at both ends of the upper end of the combustion device body 2, near the side of the air duct 4.
