Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal smelting roasting furnace technology, specifically to an adjustable discharge blocking device for a zinc smelting roasting furnace. Background Technology
[0002] In the current hydrometallurgical zinc smelting industry, the fluidized bed roaster is a key piece of equipment for processing zinc concentrate to obtain zinc roasted ore. During this process, the zinc concentrate enters the furnace through the discharge port and reaches a fluidized state within the roaster, thus fully reacting to generate roasted ore. The ore is then discharged from the furnace through the discharge port and falls into the roasted ore conveying equipment below the discharge port for transport.
[0003] However, when the calcining conveying equipment malfunctions and requires repair, it is usually necessary to temporarily block the discharge from the calcining furnace to gain 1-3 hours of repair time, thereby avoiding a short-term shutdown of the calcining furnace. Traditional fluidized bed calcining furnaces typically use fixed baffles to achieve this, but this method requires workers to be present at the discharge port of the calcining furnace, posing a significant safety risk. Furthermore, when the temporary interruption of discharge ends and discharge needs to be resumed, the baffles must be manually raised gradually, and after each section is raised, a certain period of time needs to be maintained to stabilize the discharge rate. The entire process requires workers to be present at all times, which not only increases the labor intensity of the workers but also poses a significant safety risk. Summary of the Invention
[0004] This invention addresses the safety hazard of existing technologies where workers need to operate a baffle at the discharge port of the calcining furnace to block or resume material discharge, thus posing a significant safety risk. It provides an adjustable discharge blocking device for zinc smelting calcining furnaces. This device allows workers to block material discharge from the furnace without needing to operate at the discharge port, and its operation is simple.
[0005] The technical solution of this utility model is: an adjustable discharge blocking device for a zinc smelting roasting furnace, including a baffle, a rotating rod and a support. The support is used to support the baffle and the rotating rod. A rack is provided on the right side of the baffle. The rotating rod is located on the right side of the baffle and can rotate relative to the support. A gear is provided at the end of the rotating rod near the baffle. The gear meshes with the rack, so that rotating the rotating rod can drive the baffle to shift its position in the vertical direction.
[0006] By adopting the above solution, the baffle and rotating rod are supported by a bracket, and racks and gears are respectively installed on the baffle and rotating rod. The gears mesh with the racks, so that rotating the rotating rod can drive the gears to rotate. In turn, through the transmission between the gears and the racks, the baffle can be shifted in the vertical direction. This allows the opening and closing of the discharge port of the roasting furnace and the size of the opening and closing to be controlled by rotating the rotating rod. This achieves convenient adjustment of the discharge blockage of the roasting furnace and solves the problems of high labor intensity and high safety risks caused by manually lifting and placing the baffle in the traditional method.
[0007] Based on the above solution, the present invention can be further improved as follows:
[0008] Furthermore, the bracket includes a bracket one and a bracket two. The bracket one is used to support the baffle, and guide grooves are provided on the bracket one on both sides of the baffle. The length direction of the guide grooves is consistent with the length direction of the rack. The rotating rod is rotatably connected to the bracket two.
[0009] The above-mentioned further solution involves supporting the baffle with a bracket, and providing guide grooves on the brackets on both sides of the baffle that are aligned with the length direction of the rack. This allows the guide grooves to guide the baffle as it moves, preventing it from shaking or shifting during movement, thus ensuring the accuracy and stability of the material discharge blocking.
[0010] Furthermore, the length direction of both the rack and the guide groove is vertical, which enables the baffle to effectively block the discharge of material from the roasting furnace.
[0011] Furthermore, the rotating rod is positioned perpendicular to the baffle, allowing the gear and rack to mesh well, thereby reducing wear during transmission.
[0012] Furthermore, the second bracket includes a sleeve rod, the rotating rod passes through the sleeve rod and is rotatably connected to the sleeve rod, and the two ends of the rotating rod are respectively located outside the two ends of the sleeve rod; so that the rotating rod can rotate stably, thereby driving the gear to rotate, and thus realizing the adjustment of the position of the baffle.
[0013] Furthermore, a handwheel is provided at the end of the rotating rod away from the baffle. By turning the handwheel, the rotating rod can be rotated, providing a convenient operating position for the operator.
[0014] Furthermore, the gear is a spur gear.
[0015] Furthermore, the length of the rotating rod is 150cm to 250cm.
[0016] The beneficial effects of this utility model through the above technical solution are as follows:
[0017] 1. In this utility model, a baffle and a rotating rod are supported by a bracket, and a rack and a gear are respectively set on the baffle and the rotating rod. The gear and the rack mesh with each other, so that rotating the rotating rod can drive the gear to rotate. In turn, through the transmission of the gear and the rack, the baffle can be moved vertically. This allows the opening and closing of the discharge port of the roasting furnace and the size of the opening and closing of the discharge port to be controlled by rotating the rotating rod. This realizes the convenient adjustment of the discharge blockage of the roasting furnace and solves the problems of high labor intensity and high safety risks caused by manually lifting and placing the baffle in the traditional method.
[0018] 2. In a further embodiment of this utility model, the baffle is supported by a bracket, and guide grooves are provided on the brackets on both sides of the baffle, which are aligned with the length direction of the rack. This allows the guide grooves to guide the baffle as it moves, preventing it from shaking or shifting during movement, thereby ensuring the accuracy and stability of the material discharge blocking.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0023] like Figures 1-2 As shown, an adjustable discharge blocking device for a zinc smelting roasting furnace includes a baffle 1, a rotating rod 2, and a support. The support supports the baffle 1 and the rotating rod 2. A rack 3 is provided on the right side of the baffle 1, which is the side of the baffle 1 away from the discharge port of the roasting furnace. The length direction of the rack 3 is vertical. The rotating rod 2 is located on the right side of the baffle 1 and can rotate relative to the support. A gear 4 is provided at the end of the rotating rod 2 near the baffle 1, and a handwheel 9 is provided at the end of the rotating rod 2 away from the baffle 1. The rotating rod 2 is perpendicular to the baffle 1, and the gear 4 is a spur gear. The gear 4 meshes with the rack 3, so that rotating the rotating rod 2 by the handwheel 9 can drive the gear 4 to rotate. Through the transmission between the gear 4 and the rack 3, the baffle 1 can be moved in the vertical direction. Thus, rotating the handwheel 9 can drive the baffle 1 to move in the vertical direction, thereby controlling the opening and closing of the discharge port of the roasting furnace and the size of the opening and closing of the discharge port.
[0024] In this embodiment, the blocking device is used to block the discharge of the Lurgi-type roasting furnace. The Lurgi-type roasting furnace operates at a temperature of 900℃ to 1000℃, has a discharge port height of 50cm, a discharge port width of 40cm, and a discharge port distance of approximately 100cm from the ground. Therefore, in this embodiment, a baffle 1 with a height of 70cm and a width of 60cm is used to block the discharge of the roasting furnace. When the baffle 1 blocks the discharge of the roasting furnace, it moves from top to bottom, and when the baffle 1 opens the discharge port of the roasting furnace, it moves from bottom to top. Furthermore, because the operating temperature of the Lurgi-type roasting furnace is high in this embodiment, the temperature of the baffle 1 and the temperature of the rotating rod 2 near the baffle 1 will be high. According to experiments in actual scenarios, the rotating rod 2 within 100cm of the discharge port of the roasting furnace cannot be touched by human hands. Therefore, in this embodiment, the length of the rotating rod 2 is 250cm.
[0025] In one possible implementation, the support includes a first support 5 and a second support 6. The first support 5 is fixed on the ground and is used to support the baffle 1. Guide grooves 7 are provided on the first support 5 on both sides of the baffle 1, and the two sides of the baffle 1 are engaged in the guide grooves 7. The length direction of the guide grooves 7 is consistent with the length direction of the rack 3, so that when the baffle 1 moves, the guide grooves 7 can guide the baffle 1 and prevent the baffle 1 from shaking or deviating during the movement. The rotating rod 2 is rotatably connected to the second support 6.
[0026] In one possible implementation, the second bracket 6 includes a sleeve rod 8, the rotating rod 2 passes through the sleeve rod 8 and is rotatably connected to the sleeve rod 8, and the two ends of the rotating rod 2 are respectively located outside the two ends of the sleeve rod 8.
[0027] In this embodiment, the sleeve rod 8 is 250cm long, and bearings are installed inside the sleeve rod 8 and at both ends. The rotating rod 2 is rotatably connected to the sleeve rod 8 through the bearings, so that the rotating rod 2 can rotate stably, thereby driving the gear 4 to rotate and realizing the adjustment of the position of the baffle 1.
[0028] As one possible implementation, the second bracket 6 further includes a supporting steel bar 10, one end of which is fixedly connected to the sleeve rod 8 and the other end of which is fixedly connected to the first bracket 5. The supporting steel bar 10 includes four inclined steel bars and a reinforcing bar located between two inclined steel bars. In order to further ensure the stability of the sleeve rod 8, a support frame can also be set on the ground to support the sleeve rod 8.
[0029] In this embodiment, when used:
[0030] When it is necessary to block the discharge of the roasting furnace, the operator drives the rotating rod 2 and gear 4 to rotate by turning the handwheel 9. Through the meshing of gear 4 and rack 3, the baffle 1 is driven to move downward in the vertical direction along the guide groove 7. The discharge of the roasting furnace is observed gradually during the movement of the baffle 1.
[0031] When it is necessary to open the discharge port of the roasting furnace, the operator drives the rotating rod 2 and gear 4 to rotate in the opposite direction by turning the handwheel 9 in the opposite direction, thereby driving the baffle 1 to move upward in the vertical direction along the guide groove 7. During the movement of the baffle 1, the operator gradually observes the discharge of the roasting furnace to ensure the discharge speed.
