Description

Technical Field

[0001] The utility model specifically relates to the field of automobile parts production, and particularly relates to an aluminum liquid melting and stirring device. Background Technique

[0002] Automobile parts are various units that make up an automobile as a whole and a kind of product that serves the automobile. With the improvement of people's living standards, people's consumption of automobiles is increasing, and the market for automobile parts is also becoming larger and larger.

[0003] In the production process of automobile parts, die-casting molding method is usually used to process automobile parts. First, aluminum ingots and metal raw materials are put into a furnace for melting and heating up, and then the aluminum liquid is stirred and argon gas is introduced to reduce the hydrogen content in the aluminum liquid, so as to avoid the situation that pores are generated in automobile parts due to too high hydrogen content. And it is necessary to introduce a impurity removing agent into the aluminum liquid, and the impurities in the aluminum liquid are removed through a conveyor belt. For example, CN218465907U, named an aluminum liquid stirring degasser, "the input method of the impurity removing agent is mainly to add the impurity removing agent in the box into the furnace through a feeding component, and after the addition is completed, the box and the feeding component are moved out of the furnace range through the conveyor belt of the moving component". However, during the process of putting the impurity removing agent into the furnace, due to the introduction of argon gas into the aluminum liquid, the argon gas will emerge from the aluminum liquid. Before the impurity removing agent contacts the aluminum liquid, the argon gas emerging from the aluminum liquid will blow part of the impurity removing agent onto the side wall of the furnace, and only the impurity removing agent that is not blown onto the melting wall contacts the aluminum liquid, so that the impurity removing agent cannot fully remove impurities from the aluminum liquid, resulting in waste of the impurity removing agent and extremely low impurity removal efficiency, and it will also affect the quality of automobile parts. Content of the Utility Model

[0004] The purpose of the utility model is to provide an aluminum liquid melting and stirring device capable of accurately inputting an impurity removing agent for the deficiencies of the prior art, so as to solve the technical problem that the impurity removing agent in the prior art cannot fully remove impurities from the aluminum liquid, which will affect the quality of automobile parts.

[0005] The purpose of the utility model can be realized by the following technical solutions:

[0006] An aluminum liquid melting and stirring device includes a base plate, on which a column and a pressure tank are arranged. A first motor is arranged on the column, the output end of the first motor is connected with a chain in a transmission manner, an adjusting plate is slidably matched on the column, the adjusting plate is connected with the chain in a transmission manner, a second motor and a mixing block are arranged on the adjusting plate, a stirring head is coaxially arranged at the output end of the second motor, an air outlet pipe of the pressure tank is fixedly connected with an air inlet pipe of the mixing block, the air inlet pipe of the mixing block is fixedly installed with a box body in a sealed manner, a supporting plate is arranged on the mixing block, a leakage hole is formed in the supporting plate, and the box body is communicated with the leakage hole.

[0007] As a further optimization or improvement of this solution, a limiting groove is provided on the column, and the adjusting plate is slidably limited by the limiting groove.

[0008] As a further optimization or improvement of this solution, a guide rail is provided on the column, and the adjusting plate is slidably guided by the guide rail.

[0011] As a further optimization or improvement of this solution, a baffle is rotatably installed on the output shaft of the second motor.

[0012] The beneficial effects of the present utility model: By adjusting the height of the adjusting plate through the first motor, the stirring head rotates in the melting furnace. Under the action of the pressurizing tank, argon gas pushes the blades on the rotating shaft to rotate, so that the impurity removing agent falling through the leakage holes in the box body onto the blades is accompanied by the air flow hitting the blades and introduced into the mixing pipe.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1-5 A device for stirring aluminum liquid for melting and melting, comprising a base plate 1, on which a column 2 and a pressurizing tank 3 are arranged, on which a height-adjustable adjusting plate 5 is slidably matched, and the adjusting plate 5 is transmission-connected with a chain 8, on which a second motor 11 and a mixing block 9 are arranged, a mixing tube 18 is provided in the mixing block 9, a rotating shaft 15 is rotatably installed in the mixing tube 18, a plurality of blades are arranged in a circle on the rotating shaft 15, and the blades are attached to the inner wall of a supporting plate 16, and a stirring head is coaxially arranged at the output end of the second motor 11 13. The gas outlet of the pressurized tank 3 is fixedly connected with the gas pipe 4, the gas pipe 4 is communicated with the mixing tube 18, and the argon gas flowing in the mixing tube 18 interferes with the blades. The mixing block 9 is sealed with a box 10, and the mixing block 9 is provided with a support plate 16. The support plate 16 is arched, and a leakage hole 17 is opened on the support plate 16. The box 10 is communicated with the leakage hole 17, and the support plate 16 is arranged in an arc shape, so that the blades of the rotating shaft 15 can better fit with the inner wall of the support plate 16, so as to prevent the argon gas from entering the box 10 through the rotating shaft 15.

[0022] The implementation principle of the present utility model is as follows: Before the equipment works, the equipment needs to be adjusted. The output end of the first motor 6 is rotationally connected with a chain 8, and the chain 8 is in transmission connection with the adjusting plate 5. By starting the first motor 6, the lifting of the adjusting plate 5 can be realized. During the lifting process of the adjusting plate 5, when the stirring head 13 coaxially connected to the output end of the second motor 11 enters the molten aluminum, the adjustment work is completed. Then, start the second motor 11 to make the stirring head 13 stir the molten aluminum. Start the pressure tank 3, and the pressure tank 3 injects argon into the gas transmission pipe 4. When the argon in the gas transmission pipe 4 enters the mixing pipe 18 of the mixing block 9, the argon under the action of the pressure tank 3 pushes the blades on the rotating shaft 15 to rotate, so that the impurity removing agent falling on the blades through the leakage holes 17 in the box body 10 enters the mixing pipe 18 along with the airflow hitting the blades, and under the action of the pressure tank 3, the argon blows the impurity removing agent into the molten aluminum together, so that the impurity removing agent can fully contact the molten aluminum and effectively remove the impurities in the molten aluminum. In order to prevent the blades on the rotating shaft 15 from rotating too fast and causing the impurity removing agent on the blades to splash everywhere, the flow rate and velocity of the argon can be controlled by the pressure tank 3 to make the rotation speed of the blades on the rotating shaft 15 uniform and avoid the impurity removing agent splashing everywhere due to the too fast rotation speed of the blades. After the impurity removal of the molten aluminum is completed, start the first motor 6 to withdraw the stirring head 13 from the furnace, and the stirring ends.

[0023] Specifically, refer to Figures 1-3 , a limiting groove 7 is provided on the column 2, and the adjusting plate 5 is slidably limited with the limiting groove 7. A guide rail 14 is provided on the column 2, and the adjusting plate 5 is slidably guided with the guide rail 14; when the first motor 6 works, the lifting of the adjusting plate 5 can be adjusted. During the lifting process of the adjusting plate 5, through the sliding of the guide rail 14 provided on the column 2 and the adjusting plate 5, the guiding function during the lifting process of the adjusting plate 5 can be realized. Also, through the sliding fit of the limiting groove 7 provided on the column 2 and the adjusting plate 5, the limiting function during the lifting process of the adjusting plate 5 can be realized, so that the adjusting plate 5 slides within the range of the limiting groove 7.

[0024] Refer to Figure 4 , a mixing pipe 18 is provided in the mixing block 9, the gas transmission pipe 4 is communicated with the mixing pipe 18, and a rotating shaft 15 is rotatably installed in the mixing pipe 18, and the rotating shaft 15 fits the inner wall of the support plate 16; in actual use, when the pressure tank 3 is started, the pressure tank 3 provides power for the argon transmission. When passing through the mixing pipe 18, the argon pushes the fan blades of the rotating shaft 15, so that the rotating shaft 15 rotates along the inner wall of the support plate 16. During this process, the impurity removing agent in the box body 10 continuously leaks to the fan blades of the rotating shaft 15 through the leakage holes 17. The rotation of the rotating shaft 15 drives the impurity removing agent to continuously fall into the mixing pipe 18, and is conveyed into the molten aluminum together under the push of the argon. Under the stirring of the stirring head 13, the impurity removing agent fully contacts the molten aluminum, ensuring the full and effective removal of the impurities in the molten aluminum.

[0025] Refer to Figures 4-5, a slot 20 is formed in the box body 10, and the plug rod 19 is slidably inserted into the slot 20. A feeding door 21 is rotatably installed on the box body 10. During actual use, the bottom end inside the box body 10 is arranged in an inclined plane to prevent the impurity removing agent from accumulating inside the box body 10. The feeding door 21 provides a sealed environment for the box body 10 to prevent other impurities from entering the box body 10, thereby affecting the quality of auto parts. After the aluminum liquid impurity removal is completed, the plug rod 19 is inserted into the slot 20 inside the box body 10. At this time, the box body 10 and the mixing pipe 18 can be separated, thereby preventing the argon gas in the mixing pipe 18 from diffusing into the box body 10 and also preventing the impurity removing agent in the box body 10 from entering the mixing pipe 18.

[0026] See Figure 1 , a baffle 12 is rotatably installed on the output shaft of the second motor 11. During actual use, the baffle 12 can prevent the aluminum liquid from splashing due to excessive stirring force of the stirring head 13, thereby avoiding waste of aluminum liquid and protecting workers from being splashed by the aluminum liquid.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principle of the present invention.
