[0017] Figure 2 is a cross-sectional view of the stirring device of the present invention. DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0019] A kind of Figure 1-2The semi-solid pulping device shown comprises a soup ladle 15, the bottom of which is provided with a water inlet 13, a sealing plug 18 which is vertically movable and can block the water inlet 13 is arranged inside the soup ladle 15, and the water inlet 13 is opened and closed by the vertical lifting movement of the sealing plug 18. A sealing fixing plate 14 is arranged at the upper end of the soup ladle 15, a master control device plate 6 is arranged above the sealing fixing plate 14, a master controller fixing cover plate 3 is arranged in the middle of the master control device plate 6, and a lifting controller 20 for driving the sealing plug 18 is arranged on the master controller fixing cover plate 3. The main controller fixed cover 3 is provided with a stirring device extending into the soup spoon 15, and the stirring device includes a motor 1 arranged on the top surface of the main controller fixed cover plate 3, a cross-plum blossom rotating key 12, a transmission connection ring 8, a connecting key 11, a stirring rod 16, and a guide ring 9 arranged below the main controller fixed cover plate 3, wherein the cross-plum blossom rotating key 12 is connected to the output shaft of the motor 1, the cross-plum blossom rotating key 12 is meshed with the inner side of the transmission connection ring 8 for transmission, the transmission connection ring 8 is connected to the stirring rod 16 through the connecting key 11, and the outer side of the stirring rod 16 is slidably matched with the inner wall of the guide ring 9. There are multiple stirring rods 16, and the multiple stirring rods 16 are evenly distributed on the outer periphery of the transmission connection ring 8, and the lower end of the stirring rod 16 is connected to a stirring head 17.

[0020] When the soup spoon 15 has taken the soup, the motor 1 starts, drives the cross-plum blossom rotating key 12 to transmit the transmission to the stirring rod transmission connecting ring 8, and then the stirring rod 16 is rotated along the inner wall of the guide ring 9 through the stirring rod connecting key 11. The stirring rod 16 drives the stirring head 17 to stir the aluminum alloy liquid. An automatic alloy element feeding device 2 is provided on the fixed cover plate 3 of the main controller. Alloy elements can be added while stirring, so as to supplement the alloy elements in the aluminum alloy and obtain an aluminum alloy semi-solid slurry of a predetermined composition. A lubricating oil groove is provided on the fixed cover plate 3 of the main controller, and the lubricating oil groove extends to the inner wall of the guide ring 9, which is used for sliding lubrication of the guide ring 9 and the stirring rod 16.

[0021] The sealing fixing plate 14 and the assembly control plate 6 are directly provided with a plurality of support rods 7, and the plurality of support rods 7 are evenly distributed on the sealing fixing plate 14. The support rods 7 are used to support and connect the sealing fixing plate 14 and the assembly control plate 6.

[0022] like Figure 1 As shown, the side wall of the soup spoon 15 is a double-layer structure, with a first inner cavity 24 in the middle. A liquid filling controller 19 is arranged on the main controller fixed cover plate 3, and the liquid filling controller 19 is connected to the first inner cavity 24 through a first pipe 22, and the first inner cavity 24 is also connected to the lifting controller 20 through a second pipe 21. The liquid filling controller 19 is used to add volatile liquid to the first inner cavity 24. The lifting controller 20 includes a rod cavity and a rodless cavity, wherein the first pipe 22 is connected to the rod cavity, and the rodless cavity is connected to a recovery pipe 23, and the rod cavity and the rodless cavity are connected through a small hole on the piston.

[0023] The cooling of the entire pulping device is to use a stirring head to stir and dissipate heat. After the temperature drops to a certain level, the liquid filling controller is started, and then a volatile liquid, such as water or volatile oil, is added to the first inner cavity 24 through the first pipe 22. After the filling is completed, the liquid filling controller 19 is automatically closed, and the aluminum liquid in the spoon 15 is continuously stirred. At this time, the volatile liquid vaporizes and takes away a large amount of heat, which can cool the aluminum liquid again. At the same time, the high-temperature steam chamber formed by vaporization in the middle cavity of the spoon isolates the external environment, so that the spoon 15 has a good insulation effect and the temperature of the aluminum liquid is stable.

[0024] When the soup spoon enters the state of pouring aluminum liquid, the second pipe 21 opens, and transmits its own high-pressure gas to the rod chamber of the lifting controller 20, so that the sealing plug 8 rises. The recovery pipe 23 draws out the gas entering the rodless chamber. Therefore, under the state of positive pressure in the rod chamber and negative pressure in the rodless chamber, the sealing plug 8 remains in the lifted state. At this time, the water intake 13 is opened to complete the casting. When the soup is taken, the recovery pipe 23 needs to be fed with positive pressure to make the pressure in the rodless chamber greater than the pressure in the rod chamber, so that the sealing plug 8 can close the water intake.

[0025] In order to achieve a better heat preservation effect of the soup spoon 15 and prevent the heat from dissipating too quickly, the bottom of the soup spoon 15 has a second inner cavity 25, and the inner wall of the second inner cavity 25 has a heat insulation coating.

[0026] In order to facilitate taking out the soup, an air pressure balance valve 10 is provided on the sealing fixing plate 14 of the present invention to ensure that the air pressure in the soup spoon 15 is balanced during the process of taking out the soup.

[0027] The lifting controller 20 is connected to the sealing plug 18 through a connecting rod 5, and a thermocouple 4 is arranged in the connecting rod 5. The temperature of the aluminum liquid in the spoon 15 is monitored by the thermocouple 4. Once the temperature reaches the set temperature, the motor 1 stops, that is, the stirring stops, and the aluminum liquid is ready to be poured.

[0028] The technical solutions provided by the embodiments of the present invention are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
