Description

Technical Field

[0001] The utility model belongs to the technical field of furnace refining auxiliary equipment, and in particular relates to a cart used for aluminum smelting and refining. Background Art

[0002] Aluminum melting furnace is a new type of high-efficiency and energy-saving furnace developed according to aluminum smelting process. It can well meet the requirements of alloy composition preparation in aluminum smelting process. After preparing the alloy, refining operation is required for degassing and slag removal, which is the key to improving the quality of aluminum melt. Argon and other inert gases are often used as carriers to continuously spray high-efficiency refining agents and granular refining agents into aluminum liquid through refining tubes, which can give full play to the purification effect of refining agents on aluminum liquid, effectively degas and slag, and improve the quality of aluminum melt.

[0003] At present, the workers are manually refining the refining tube in front of the molten pool. Due to the high temperature of the molten pool, the labor intensity of the workers is increased and the danger is great. During the operation, the position of the refined steel tube needs to be adjusted to move up and down, left and right, and forward and backward, which is labor-intensive. At the same time, due to the different heights of the employees and the different operation details, the refining agent cannot be sprayed evenly and inconsistently to various parts of the aluminum liquid, resulting in unstable aluminum liquid refining effect and a great risk of quality fluctuation. The second is to use automatic refining machines for automatic refining, but automatic refining cars are relatively expensive, which increases investment costs; and automatic refining cars are relatively long and cannot work normally in small areas. They have great limitations and cannot be used in all places.

[0004] The present application provides a trolley for aluminum smelting and refining. The structure realizes manual refining through the refining trolley when an automatic refining trolley cannot be used. Compared with conventional manual refining operations, the labor intensity and the influence of thermal radiation of the temperature are greatly improved during the operation; at the same time, since the refining tube does not contact the furnace threshold of the melting furnace, the friction is reduced and the service life of the furnace threshold is increased. Summary of the invention

[0005] In order to achieve the above object, the technical solution of the utility model is as follows:

[0006] A cart used for aluminum smelting and refining, comprising wheels and a frame; the wheels are mounted on the bottom of the frame through bearings, and the frame has two sets of auxiliary support rods extending from the middle section to both sides;

[0011] Furthermore, a pipeline docking valve head is installed between the rear end of the extension pipeline and the feed pipeline;

[0012] The extension pipe is provided with a locking assembly along the top of the frame.

[0013] Furthermore, the locking assembly includes a pressing buckle, a movable pressing plate and a locking handle;

DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0025] like Figure 1 and Figure 2 As shown, a cart used for aluminum smelting and refining includes wheels and a frame; the wheels 13 are mounted on the bottom of the frame 7 through bearings, and the frame 7 has two sets of auxiliary support rods 12 extending from the middle section to both sides; wherein the frame 7 is used as a supporting body, and in daily use, the wheels 13 can be used to complete daily moving tasks. The auxiliary support rods 12 are used to support and lift the extended pipe 5 with a large front and rear span.

[0026] The front auxiliary support rod 12 is connected to the extension bracket 11; the extension bracket 11 is supported on the top of the extension pipe 5, and the front end of the extension pipe 5 is connected to the arc-shaped refining pipe 9, and the output end of the arc-shaped refining pipe 9 extends into the molten pool 10; wherein, the extension bracket 11 ensures the support of the extension pipe 5. Since the front end of the extension pipe 5 is a horizontal suspension structure, the extension pipe 5 gradually sags due to its own gravity due to long-term use. Therefore, in order to avoid this phenomenon, the present application adopts the installation structure of the extension bracket 11 as the support structure for the drooping of the extension pipe 5. The arc-shaped refining pipe 9 is convenient for feeding.

[0027] The rear auxiliary support rod 12 is supported and connected with the balance rod 2; wherein, the balance rod 2 serves as a rear extension structure for balancing the frame 7, and the rod body of the balance rod 2 can be installed with a counterweight object to complete the vehicle body balancing operation process, reducing the difficulty of operation for employees.

[0028] The rear end of the extension pipeline 5 is connected to the feed pipeline 3. The extension pipeline 5, as an extension pipeline for the feed connection, can horizontally support the attack pipeline to avoid the high temperature near the molten pool 10 affecting the plastic structure of the feed pipeline. The feed pipeline is a hose structure and can be flexibly transported in a long line.

[0029] like Figure 1 and Figure 2 As shown, a pipeline docking valve head 4 is installed between the rear end of the extension pipeline 5 and the supply pipeline 3; wherein the pipeline docking valve head 4 can control the supply amount of the supply pipeline 5.

[0030] The extension pipe 5 is provided with a locking assembly 6 along the top of the vehicle frame 7. The design of the locking assembly 6 can be used for replacing or disassembling the extension pipe 5 and maintaining the vehicle body.

[0031] like Figure 1 and Figure 2As shown, the locking assembly 6 includes a buckle 14, a movable pressure plate 15 and a locking handle 16; the locking handle 16 is movably mounted on the main end face of the frame 7, and the buckle 14 is movably mounted on the upper end of the locking handle 16, and the buckle 14 is in locking contact with the movable pressure plate 15, and the movable pressure plate 15 is mounted on the rear end face of the extension bracket 11 in a flip structure. The movable pressure plate 15 and the extension pipeline 5 are in a limited installation structure. Among them, the locking assembly 6 can use the locking handle 16 installed by itself as an operating handle, and fix and limit the buckle 14 to the extension pipeline 5 through the movable pressure plate 15 to prevent the extension pipeline 5 from tilting.

[0032] like Figure 1 and Figure 2 As shown, the extension bracket 11 is provided with a balancing sleeve 8 at the front position of the molten pool 10, and the balancing sleeve 8 is in a limited contact structure with the extension pipeline 5. The balancing sleeve 8 serves as a guide contact structure, which can guide the front end of the extension pipeline 5 to extend into the opening of the molten pool 10.

[0033] like Figure 1 and Figure 2 As shown, the auxiliary support rod 12 is inclined and bent along the rear end, and a handle 1 is installed at the end of the auxiliary support rod 12, and a feed pipe 3 is mounted on the handle 1. The handle 1 is used as a vehicle body operating structure held by the employee with both hands, and is used to assist the employee in the installation process of the feed pipe 3, and can also adjust the position of the vehicle body to cooperate with smelting.

[0034] In summary, in the case where the automatic refining car cannot be used, the labor intensity of manual refining is high and the refining operation is uneven and inconsistent. A small cart is specially designed and manufactured to place the refining tube on the cart to complete the aluminum liquid refining operation. The structure of the refining cart is as follows:

[0035] 1. Purchase two 26-inch wheels 13, and use a 500 mm long rotating connecting rod to connect the two wheels 13 together through a bearing to form the wheels 13 of the refining cart;

[0036] 2. Weld two auxiliary rods with a length of 1500 mm at a 45-degree angle on the rotating connecting rod of the wheel, one for auxiliary support and the other for balance rod 2;

[0037] 3. Make a frame with a height of 900 mm vertically above the rotating connecting rod, and the frame 7 is made into a double-beam structure with a length of 600 mm and a width of 40 mm;

[0038] 4. An extended bracket 11 with a length of 2400 mm is welded on the double beam structure of the frame 7 and the auxiliary support rod using channel steel to place the refined tube and prevent the refined tube from collapsing due to heat during refining in the furnace;

[0039] 5. Two movable pressing plates and pressing buckles are welded on the vertical frame and the extended bracket 11, and the pressing plates and pressing buckles are combined to lock and fix the refined tube on the frame and the V-shaped channel steel frame, so that the refined tube does not shake or move during the refining operation. At the same time, when the refined tube needs to be replaced after the refining is completed, it is only necessary to loosen the pressing buckle and the pressing plate, which is convenient for replacing the refined tube;

[0040] 6. Weld a push rod with a length of 2400 mm on the auxiliary support rod and the auxiliary push rod, and weld a handle 1 at the rear end of the push rod to facilitate the operator to push the push rod through the handle 1 to make the refining trolley move forward and backward and left and right;

[0041] 7. Place the refining tube on the vertical frame and the extension bracket 11 and use the pressing plate and the buckle 14 to fix the extension pipe 5. Connect the hose on the refiner to the rear end of the extension pipe 5 and fix it. Turn on the switch on the refiner, manually push the refining trolley to move forward and backward and left and right to carry out the refining operation.

[0042] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
