Description

Technical Field

[0001] This utility model relates to the technical field of furnace hole blocking devices, specifically a furnace hole blocking device for aluminum processing furnaces. Background Technology

[0002] Aluminum smelting furnaces, holding furnaces and other aluminum processing furnaces all have furnace openings for discharging molten aluminum. During the use of aluminum processing furnaces, the furnace openings need to be plugged or opened.

[0003] One existing method for plugging furnace holes involves using a steel rod with a plug sleeve. This requires manual labor, which involves using a sledgehammer to drive the steel rod into or out of the furnace hole. This method is physically demanding, especially during the solidification of aluminum in the furnace hole. It also results in low work efficiency and high risk.

[0004] Patent application number 202121374894.2 discloses another solution for plugging the furnace eye and discloses a furnace eye control device for an aluminum alloy melting furnace. The device includes a plug, the front end of which is connected to the furnace eye, and the rear end of which is connected to a plug rod. An actuator is connected to the plug rod, and a reversing frame is fixedly connected to the upper end of the actuator. One end of a quadrilateral push-pull rod is connected to the reversing frame, and the other end of the quadrilateral push-pull rod is connected to an adjusting handle rod. Support base I and support base II are connected to the furnace body above the furnace eye. The adjusting handle rod is rotatably connected to support base I and support base II. When plugging the furnace eye, the adjusting handle rod is rotated to one side to move the plug to one side of the furnace eye. The locking device is pulled down to lock it with the locking rod to fix the plug.

[0005] The disadvantages of the above two methods are: manual operation of plugging the furnace hole is labor-intensive and dangerous; the force of pressing the plug against the furnace hole is not easy to control. If the force is too small, it is easy to not plug tightly, and if the force is too large, it is easy to damage the furnace hole. Utility Model Content

[0006] The main purpose of this utility model is to provide a furnace hole plugging device for aluminum processing furnaces, so as to solve the problems of manual operation of plugging furnace holes in the above-mentioned prior art, which is labor-intensive and dangerous; the force of pressing the plug against the furnace hole is not easy to control. If the force is too small, it is easy to not plug tightly, and if the force is too large, it is easy to damage the furnace hole.

[0007] To achieve the above objectives, this utility model provides a furnace hole plugging device for aluminum processing furnaces, including a support frame fixedly connected to the furnace body. The support frame is hinged to the top ends of two connecting rods, and the bottom ends of the two connecting rods are hinged to connecting rods. The two connecting rods are parallel and of equal length. A plug holder is fixedly connected to the end of the connecting rod near the furnace body, and a plug is provided at the end of the plug holder near the furnace body. A cylinder is hinged to the support frame, and one of the connecting rods is hinged to the end of the piston rod of the cylinder.

[0008] Furthermore, the connecting rod and the end cap bracket are connected by a buffer device, which includes at least three parallel sliding rods; two sliding plates are slidably connected to the sliding rods, and limit heads that prevent the sliding plates from sliding off the sliding rods are fixedly connected to both ends of the sliding rods; a spring is sleeved on the sliding rod, and the spring is located between the two sliding plates.

[0009] Furthermore, the furnace body is fixedly connected with connecting ears; the support frame is a U-shaped rod, one end of the support frame is hinged to the connecting ear, and the other end is fixed to the connecting ear by inserting a rod; both the support frame and the connecting ear are provided with insertion holes.

[0010] Furthermore, an extension rod is fixedly connected to the connecting rod, a locking frame is fixedly connected to the support frame, a locking rod is threaded onto the locking frame, and a locking hook is fixedly connected to the end of the locking rod away from the locking frame; the locking hook can be rotated to the front of the extension rod to lock it, and can also be rotated to the top of the extension rod to release the lock.

[0011] This invention, by incorporating a cylinder, enables remote control of plugging or removing the plug from the furnace bore, reducing the labor intensity for workers. Furthermore, workers can control the cylinder from a distance, preventing molten aluminum from splashing and causing injury, thus enhancing safety. By setting up a connecting rod frame and connecting rods to form a parallelogram mechanism, the movement of the plug frame can be controlled more stably.

[0012] This invention, by incorporating a buffer device, can buffer the process of pressing the plug into the furnace hole, preventing excessive pressing force from damaging the furnace hole and insufficient pressing force from causing a loose seal; thus ensuring a tight connection between the plug and the furnace hole and a better sealing effect.

[0013] This utility model, by hinged to one end of the support frame and fixed by inserting the other end, allows the support frame to be rotated to one side of the furnace body when manually plugging the furnace hole during maintenance of the furnace hole plugging device in aluminum processing furnaces.

[0014] This invention, by setting locking devices such as locking rods and locking hooks, can lock the plug after it has been plugged into the furnace hole, preventing the plug from being pushed out and causing aluminum liquid leakage. Attached Figure Description

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Example 1 like Figures 1 to 2 As shown, an aluminum processing furnace plugging device is applied to an aluminum smelting furnace or holding furnace with a capacity of 25-32 tons. It includes a support frame 2 fixedly connected to the furnace body 1. The support frame 2 is hinged to the top ends of two connecting rods 3, and the bottom ends of the two connecting rods 3 are hinged to connecting rods 4. The two connecting rods 3 are parallel and of equal length. The support frame 2, connecting rods 4, and connecting rods 3 form a parallelogram mechanism. A plug frame 5 is fixedly connected to the end of the connecting rod 4 near the furnace body 1. The plug frame 5 is an L-shaped rod, and a plug 501 is provided at the end of the plug frame 5 near the furnace body 1. A cylinder 6 of model MBT80 is hinged to the support frame 2. One of the connecting rods 3 is hinged to the end of the piston rod of the cylinder 6. The cylinder 6 is connected to an air tank via an air pipe, and the air tank is connected to an air compressor. A reversing valve for controlling the extension and retraction of the cylinder 6 is provided on the air pipe.

[0020] When the piston rod of cylinder 6 extends, it drives the parallelogram mechanism to move and press the plug 501 into the furnace hole; when the piston rod of cylinder 6 retracts, it drives the parallelogram mechanism to move and pull the plug 501 out of the furnace hole.

[0021] Link 4 and end cap 5 are connected by a buffer device 7, which includes four parallel sliding rods 702. Two square sliding plates 701 are slidably connected to the sliding rods 702. The four corners of the sliding plates 701 are provided with sliding holes for the sliding rods 702 to slide. Limiting heads 703 are fixedly connected to both ends of the sliding rods 702 to prevent the sliding plates 701 from sliding out of the sliding rods. A spring 704 is sleeved on the sliding rods 702 and is located between the two sliding plates 701. The sliding rods 702 limit the direction of movement of the sliding plates 701, and the springs 704 provide a buffering effect.

[0022] By setting the buffer device 7, the plug 501 can play a buffering role during the process of being pressed into the furnace hole, avoiding excessive pressing force that could damage the furnace hole, and also avoiding insufficient pressing force that could not be properly sealed; thus, the plug 501 and the furnace hole are tightly connected, resulting in a better sealing effect.

[0023] Example 2 like Figures 3 to 4 As shown, the furnace hole plugging device for an aluminum processing furnace differs from the furnace hole plugging device in Example 1 only in that: A connecting lug 101 is fixedly connected to the furnace body 1; the support frame 2 is a U-shaped rod, one end of the support frame 2 is hinged to the connecting lug 101, and the other end is fixed to the connecting lug 101 by inserting a rod 8; both the support frame 2 and the connecting lug 101 are provided with insertion holes for inserting the rod 8.

[0024] The support frame is hinged to one end of the furnace body and inserted and fixed at the other end. When repairing the furnace hole blocking device of the aluminum processing furnace and manually blocking the furnace hole, the support frame can be rotated to one side of the furnace body.

[0025] Example 3 like Figure 1 As shown, the aluminum processing furnace hole-blocking device differs from the aluminum processing furnace hole-blocking device in Example 2 only in that: One of the connecting rods 3 has an extension rod 9 fixedly connected to its top, and a locking frame 10 is fixedly connected to the support frame 2. A locking rod 11 is threadedly connected to the locking frame 10, and a locking hook 12 is fixedly connected to the end of the locking rod 11 away from the locking frame 10. The locking hook 12 can be rotated to the front of the extension rod 9 to lock it, and can also be rotated to the top of the extension rod 9 to release the lock.

[0026] By setting locking devices such as locking rod 11 and locking hook 12, the plug 501 can be locked after it is plugged into the furnace hole, preventing the plug 501 from being pushed out and causing aluminum liquid to leak.

[0027] In the above embodiments 1-3, by setting cylinder 6, the plugging of the furnace hole or the removal of the plug can be controlled remotely through cylinder 6, reducing the labor intensity of workers; and workers can control cylinder 6 from a distance from the furnace hole, avoiding splashing of aluminum liquid and causing injury, which is safer; by setting linkage frame 3 and linkage 4 to form a parallelogram mechanism, the movement of plug frame 5 can be controlled more stably.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
