Description

Technical Field

[0001] This utility model relates to the field of aluminum processing technology, specifically to a degassing chamber body and the degassing chamber itself. Background Technology

[0002] The degassing chamber is a core component in modern aluminum melting and die casting processes to ensure the purity of molten aluminum. It is mainly used to remove dissolved hydrogen and impurities from the molten aluminum.

[0003] A degassing chamber generally includes a chamber body 1 with an open top, a degassing device located at the opening at the top of the chamber body 1, a control system for controlling the operation of the degassing device, and a heating and insulation system for heating and maintaining the temperature of the molten aluminum inside the chamber body 1. The top side wall of the chamber body 1 has an aluminum liquid inlet and an aluminum liquid outlet, both of which are equipped with airlocks 2. During operation: the chamber body 1 maintains a certain liquid level, ensuring that the ports connecting the aluminum liquid inlet and outlet to the chamber body 1 are below the liquid surface; the airlocks 2 are closed, creating a sealed space within the chamber body 1. Degassing is achieved by adjusting the pressure, etc. However, the airlock side wall structure is not strong enough and is prone to damage under pressure (e.g., Figure 1 The circled area indicates the location where the air lock 2 is easily damaged. This causes the space above the liquid level in chamber 1 to be connected to the outside air through the air lock 2, preventing the formation of a sealed space in chamber 1, the regulation of the pressure inside chamber 1, and the inability to perform degassing. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a degassing chamber body and degassing chamber, so as to solve the problem that in the existing technology, air locks are set on the aluminum liquid inlet and aluminum liquid outlet, and the air locks are easy to be damaged, resulting in the space above the liquid surface in the chamber being connected to the outside air and unable to perform degassing work.

[0005] To achieve the above objectives, the first aspect of this utility model adopts the following technical solution: a chamber body for a degassing chamber, comprising a chamber body body and a liquid inlet structure and a liquid outlet structure disposed on the chamber body body, wherein the liquid inlet structure and the liquid outlet structure have the same structure and are both integrally formed with the chamber body body, and the liquid inlet structure includes:

[0006] The channel carrier is integrally formed on the outer wall of the chamber body and distributed along the height direction of the chamber body.

[0007] A liquid guiding channel is provided, wherein one end of the liquid guiding channel is located outside the top side of the chamber body, and the other end extends to the inner wall of the bottom side of the chamber body.

[0008] The second aspect of this utility model adopts the following technical solution: a degassing chamber, including the chamber body of a degassing chamber as described in the first aspect of this utility model.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The degassing chamber is integrally formed with the chamber body, liquid inlet structure, and liquid outlet structure, both of which are integrally formed on the outer wall of the chamber body. The liquid inlet structure uses a liquid guiding channel to guide molten aluminum into the chamber body, while the liquid outlet structure uses a liquid guiding channel to drain the molten aluminum from the chamber body. The arrangement of these guiding channels ensures a sufficiently high liquid level within the chamber body during operation, and the guiding channels in both the liquid inlet and outlet structures also maintain a sufficiently high liquid level to effectively isolate the external space from the space above the liquid surface within the chamber body. Furthermore, the sidewalls of the channel carrier and the sidewalls of the chamber body form a sufficiently strong insulating layer between the space within the chamber body and the guiding channels, ensuring that no damage occurs during use. The space above the liquid surface within the chamber body is not connected to the external space through the guiding channels, allowing for stable degassing operations. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described in detail below through specific embodiments:

[0018] like Figure 1 As shown in the figure, this utility model embodiment proposes a degassing chamber body, including a chamber body 3 and a liquid inlet structure 4 and a liquid outlet structure 5 disposed on the chamber body 3. The liquid inlet structure 4 and the liquid outlet structure 5 have the same structure and are integrally formed with the chamber body 3. The liquid inlet structure 4 includes a channel carrier 41 and a liquid guiding channel 42. The channel carrier 41 is integrally formed on the outer wall of the chamber body 3 and distributed along the height direction of the chamber body 3. The liquid guiding channel 42 is opened in the channel carrier 41, with one end located outside the top side of the chamber body 3 and the other end extending to the inner wall of the bottom side of the chamber body 3.

[0019] The degassing chamber is integrally formed by the chamber body 3, the liquid inlet structure 4, and the liquid outlet structure 5. Both the liquid inlet structure 4 and the liquid outlet structure 5 are integrally formed on the outer wall of the chamber body 3. The liquid guide channel 42 in the liquid inlet structure 4 guides molten aluminum into the chamber body 3, and the liquid guide channel 42 in the liquid outlet structure 5 guides molten aluminum out of the chamber body 3. The arrangement of the liquid guide channel 42 is such that, during operation, the liquid level inside the chamber body 3 is sufficiently high, and the liquid guide channel 42 in the liquid inlet structure 4 and the liquid outlet structure 5 also has a sufficiently high liquid level to effectively isolate the external space from the space above the liquid surface inside the chamber body 3. Furthermore, the side wall of the channel carrier 41 and the side wall of the chamber body 3 form a sufficiently strong insulating layer between the space inside the chamber body 3 and the liquid guide channel 42, ensuring that no damage occurs during use. The space above the liquid surface inside the chamber body 3 will not be connected to the external space through the liquid guide channel 42, enabling the degassing operation to proceed stably.

[0020] To better understand this solution, further structural optimizations are presented below.

[0021] like Figure 2 As shown, according to another embodiment of the present invention, the chamber body of the degassing chamber, wherein the liquid guiding channel 42 includes an inclined liquid guiding channel section 421 inclinedly arranged in the channel carrier 41 and a horizontal liquid guiding channel section 422 horizontally arranged in the channel carrier 41, the horizontal liquid guiding channel section 422 being connected to the top end of the inclined liquid guiding channel section 421 and the bottom end of the inclined liquid guiding channel section 421 being located on the bottom inner wall of the chamber body 3.

[0022] During use, the horizontal liquid guiding channel section 422 is connected to an external liquid guiding tank. The liquid guiding tank guides molten aluminum into the horizontal liquid guiding channel section 422 of the liquid inlet structure 4, and then into the chamber body 3 through the inclined liquid guiding channel section 421 of the liquid inlet structure 4. With a sufficiently high liquid level in the chamber body 3, the molten aluminum is discharged through the inclined liquid guiding channel section 421 of the liquid outlet structure 5, and then discharged through the horizontal liquid guiding channel section 422 of the liquid outlet structure 5 into the corresponding liquid guiding tank. The inclined liquid guiding channel section 421 is designed to maintain a sufficiently high liquid level to disconnect the air above the horizontal liquid guiding channel section 422 from the gas above the liquid level in the chamber body 3, resulting in good sealing performance within the chamber body 3. Furthermore, the inclined liquid guiding channel section 421 also causes the thickness of the side wall of the channel carrier 41 that fits against the chamber body 3 to increase sequentially from bottom to top. The side wall of the channel carrier 41 facing the horizontal liquid guiding channel section 422 has sufficient thickness, which, together with the wall thickness of the chamber body 3, ensures sufficient structural strength at this point. This prevents damage under pressure and the entry of external air into the chamber body 3, thus affecting the exhaust operation inside the chamber body 3.

[0023] Furthermore, the horizontal liquid guiding channel section 422 and the inclined liquid guiding channel section 421 are arranged on the same plane, and the horizontal liquid guiding channel section 422 is located on the side of the inclined liquid guiding channel section 421 away from the chamber body 3, so that the flow of aluminum liquid in the liquid guiding channel 42 is smoother and it is convenient to connect the liquid guiding channel 42 to the external liquid guiding tank.

[0024] Furthermore, the sidewall of the channel carrier 41 that is directly opposite the horizontal liquid guiding channel section 422 extends upwards from the horizontal liquid guiding channel section 422, ensuring that there is sufficient structural strength between the top side of the chamber body 3 and the top side of the liquid guiding channel 42 without damage.

[0025] To facilitate the cleaning of aluminum dross in the inclined liquid guiding channel section 421, such as Figure 2 As shown, according to another embodiment of the present invention, the chamber body of the degassing chamber has an opening 6 formed on the channel carrier 41 directly above the horizontal liquid guiding channel section 422, and a protective cover plate 7 is detachably connected to the opening 6.

[0026] During operation, the protective cover 7 is connected to the opening 6 to protect the area directly above the horizontal liquid guiding channel section 422. When it is necessary to clean aluminum dross inside the inclined liquid guiding channel section 421, the protective cover 7 is removed from the opening 6, making it easier to insert tools into the inclined liquid guiding channel section 421 from the opening 6 to clean the aluminum dross adhering to the inner wall of the inclined liquid guiding channel section 421.

[0027] The protective cover 7 overlaps within the opening 6 and is limited by the limiting structure 8, which facilitates the stable assembly of the protective cover 7 at the opening 6 and makes the installation or removal of the protective cover 7 more convenient.

[0028] Specifically, the limiting structure 8 includes a first limiting part 81, a second limiting part 82, a positioning notch 85, a first limiting step 83, and a second limiting step 84. The first limiting part 81 is located on one side of the opening 6 and extends upwards from the opening 6. There are two second limiting parts 82 arranged at intervals, both located on the other side of the opening 6 and extending upwards from the opening 6. There are two positioning notches 85, both of which are provided on the protective cover plate 7, for the two second limiting parts 82 to be inserted one-to-one. There are two first limiting steps 83, both of which are provided on the inner wall of the opening 6, and the two first limiting steps 83 are connected one-to-one between the two second limiting parts 82 and the first limiting part 81. There are two second limiting steps 84, both of which are provided on the protective cover plate 7. During assembly, the two second limiting steps 84 overlap the two first limiting steps 83 one-to-one, and the protective cover plate 7 abuts against the two second limiting parts 82 and the first limiting part 81.

[0029] In this embodiment, the first limiting part 81 is formed by the side wall of the channel carrier 41 and the horizontal liquid guiding channel section 422 extending upwards from the horizontal liquid guiding channel section 422. The second limiting part 82 is a protrusion formed at the top of the opening 6. The protective cover plate 7 is specifically square. When the protective cover plate 7 is assembled, the two second limiting steps 84 overlap one-to-one with the two first limiting steps 83, thereby limiting one pair of opposing sides of the protective cover plate 7. The cooperation of the first limiting part 81 and the two second limiting parts 82 limits the other pair of opposing sides of the protective cover plate 7. The two second limiting parts 82 are embedded one-to-one in the two positioning notches 85, thereby limiting the protective cover plate 7 from the front, back, left and right directions. It has sufficient assembly stability. During the assembly or disassembly of the protective cover plate 7, it can only be moved in the vertical direction.

[0030] To facilitate a stable connection to the liquid guiding tank, such as Figure 2 As shown, according to another embodiment of the present invention, the chamber body of the degassing chamber is provided with a receiving platform 9 located below the end of the liquid guiding channel 42 away from the chamber body 3.

[0031] In this embodiment, the receiving platform 9 can support one end of the liquid guiding tank, which facilitates the installation of the liquid guiding tank and enables the liquid guiding tank to communicate with the liquid guiding channel 42, so as to introduce and export molten aluminum into the chamber body 3.

[0032] Applying the chamber body of any of the above embodiments to a degassing chamber, such as... Figure 2As shown, according to another embodiment of the present invention, the degassing chamber includes a chamber body as described in any of the above embodiments, and a degassing device, a control system, and a heating and insulation system that cooperate with the chamber body 3, so that the degassing chamber has the advantages of the chamber body described above. The degassing device, control system, and heating and insulation system are existing structures mentioned in the background art and will not be further described here.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
