Description

Technical Field

[0001] This utility model belongs to the field of aluminum smelting technology, specifically relating to a precise flow control and automatic furnace hole locking device. Background Technology

[0002] During aluminum smelting, molten aluminum flows through the furnace opening into a chute and then into a mold for shaping. Each smelting furnace must have a furnace opening. After the alloy composition is adjusted and the molten aluminum is refined and purified, it is cast through the furnace opening. Before the molten aluminum is properly treated, the furnace opening is usually plugged and manually sealed to prevent the molten aluminum from leaking out. However, the manual sealing method has the following drawbacks: 1. Workers are close to the aluminum outlet or chute, posing a risk of burns; 2. It is impossible to make accurate judgments when sealing the furnace opening, resulting in inaccurate or insecure sealing. Utility Model Content

[0003] The purpose of this invention is to provide a precise flow control and automatic furnace hole locking device to solve the problem of inaccurate judgment when sealing the furnace hole.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A precise flow control and automatic furnace hole locking device includes a top plate, a connecting rod, and an adjustment mechanism disposed between the top plate and the connecting rod. The top plate and the connecting rod are arranged in parallel. One end of the top plate is provided with a connecting plate perpendicular to the top plate. A vertically extending movable opening is provided through the top plate. The adjustment mechanism includes an electric push rod, a first bracket, a second bracket, a first movable rod, a second movable rod, and a pull rod. The electric push rod includes a fixed part and a telescopic part. The fixed part is disposed above the movable opening, and the telescopic part passes through the movable opening. A first bracket is provided on the top plate and is connected to the fixed part. Tie rods are symmetrically arranged on both sides of the plate, and the tie rods are rotatably connected to the top plate. A second bracket is symmetrically arranged at the end of the top plate away from the connecting plate. A first connecting shaft is arranged between the second brackets, and a second connecting shaft is arranged between the tie rods. A first movable rod and a second movable rod are rotatably connected between the first connecting shaft and the second connecting shaft. A third connecting shaft is arranged at the bottom of the telescopic part. The third connecting shaft passes through the rotatable connection between the first movable rod and the second movable rod. The bottom end of the tie rod is connected to the two side walls of the connecting rod. The tie rod is rotatably connected to the connecting rod. A plug mechanism is arranged at the end of the connecting rod facing the connecting plate.

[0006] To further realize this utility model, the plug mechanism includes an "L"-shaped support column and a plug. The vertical end of the "L"-shaped support column is vertically inserted into the connecting rod, and the horizontal end of the "L"-shaped support column is provided with a plug. The plug extends toward the connecting plate, and the axis of the plug overlaps with the axis of the top plate.

[0007] To further realize this utility model, a guide sleeve is provided on the top surface of the connecting rod, the vertical end of the "L"-shaped support is inserted into the guide sleeve, and a tightening bolt is inserted into the side wall of the guide sleeve.

[0008] To further realize this utility model, an auxiliary tie rod group is also provided between the tie rod and the second support. The auxiliary tie rod group includes auxiliary tie rods symmetrically arranged on both sides of the top plate and the connecting rod. The auxiliary tie rods are parallel to the tie rod and are rotatably connected to the top plate and the connecting rod respectively.

[0009] To further realize this utility model, the electric push rod is perpendicular to the top plate.

[0010] To further realize this utility model, both the connecting plate and the second bracket extend downward and are perpendicular to the top plate.

[0011] To further realize this utility model, the free end of the first movable rod is rotatably connected to the first connecting shaft, and the free end of the second movable rod is rotatably connected to the second connecting shaft.

[0012] To further realize this utility model, the first connecting shaft, the second connecting shaft, and the third connecting shaft are all parallel to the top plate.

[0013] The advantages of this utility model compared to the prior art are as follows:

[0014] This invention, under the action of an electric push rod, can drive the overall linkage of the adjustment mechanism: through the extension and retraction of the telescopic part, the first and second movable rods are rotated and raised or lowered, causing the angle between the pull rod and the auxiliary pull rod and the top plate to change. The connecting rod rises or falls under the pull of the pull rod and the auxiliary pull rod until the plug is aligned with the furnace hole, thereby realizing the rapid opening and precise sealing of the furnace hole, avoiding the safety hazards caused by manual sealing, providing accurate guidance, improving work efficiency, and being convenient and easy to use.

[0015] The "L"-shaped support of this utility model is fixed in the guide sleeve by tightening bolts, which makes it easy for workers to disassemble and install the plug, and facilitates regular cleaning of the plug, avoiding the situation where aluminum liquid sticks to the outside of the plug, resulting in poor sealing.

[0016] This invention can quickly and accurately seal the furnace hole, improving work efficiency and ensuring construction safety. Attached Figure Description

The bottom end of the pull rod 10 is connected to both side walls of the connecting rod 2. The pull rod 10 is rotatably connected to the connecting rod 2. An auxiliary pull rod assembly is also provided between the pull rod 10 and the second support 7. The auxiliary pull rod assembly includes auxiliary pull rods 17 symmetrically arranged on both sides of the top plate 1 and the connecting rod 2.
