Description

Technical Field

[0001] This utility model relates to the field of aluminum processing technology, and in particular to an automatic transfer and sealing mechanism for the pouring of soup from a reverberatory furnace. Background Technology

[0002] In the aluminum processing industry, reverberatory furnaces are commonly used thermal equipment. A molten aluminum outlet pipe is installed at the outlet of the reverberatory furnace, through which molten aluminum is poured out. In existing technology, a chute is installed at the outlet pipe to guide the poured molten aluminum to downstream equipment. However, because the reverberatory furnace needs to rotate to a certain extent when pouring the molten aluminum, it is difficult to guarantee the sealing effect at the connection between the outlet pipe and the chute, easily leading to some molten aluminum dripping from the connection. In view of the above technical problems, this utility model proposes an automatic transfer and sealing mechanism for the molten aluminum outlet of a reverberatory furnace. By setting a first arc surface at the outlet end of the molten aluminum outlet pipe and a second arc surface at the inlet end of the transition chute, a good sealing effect can be maintained at the connection between the outlet pipe and the chute when the reverberatory furnace rotates at a certain angle to pour out the molten aluminum. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an automatic transfer and sealing mechanism for soup dispensing in a reverberatory furnace, which aims to solve the technical problem that the sealing effect at the outlet end of the soup dispensing pipe of the reverberatory furnace needs to be improved in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An automatic transfer and sealing mechanism for soup dispensing in a reverberatory oven includes a soup dispensing pipe, a transition trough, and a transition trough lifting device. The bottom of the outlet end of the soup dispensing pipe is provided with a first arc surface, and the inlet end of the transition trough is provided with a second arc surface. The second arc surface is located below the first arc surface, and the axis of the second arc surface is parallel to the axis of the first arc surface. The transition trough lifting device is used to drive the transition trough to rise and fall. After the transition trough rises, the second arc surface can abut against the first arc surface.

[0005] Furthermore, in the aforementioned automatic transfer sealing mechanism for soup dispensing in the reverberatory furnace, a first sealing groove is provided at the inlet end of the transition groove. The first sealing groove includes a first horizontal sealing groove and two first vertical sealing grooves. The first horizontal sealing groove is located below the soup dispensing pipe; the two first vertical sealing grooves are located outside the soup dispensing pipe; and filler is provided in both the first horizontal sealing groove and the two first vertical sealing grooves.

[0006] Furthermore, in the aforementioned automatic transfer sealing mechanism for the soup outlet of the reverberatory furnace, a third arc surface is provided at the bottom of the outlet end of the transition groove, and the axis of the third arc surface is parallel to that of the second arc surface.

[0007] Furthermore, in the aforementioned automatic transfer sealing mechanism for soup dispensing from the reverberatory furnace, a second sealing groove is provided at the outlet end of the transition groove. The second sealing groove includes a second horizontal sealing groove and two second vertical sealing grooves, and filler is provided in both the second horizontal sealing groove and the two second vertical sealing grooves.

[0008] Furthermore, in the aforementioned automatic transfer sealing mechanism for soup dispensing from the reverberatory furnace, the transition groove lifting device includes a bracket, a worm gear lifting mechanism mounted on the bracket, and a supporting top plate; the worm gear lifting mechanism includes a housing, a worm, a worm wheel, and a lead screw, with the top end of the lead screw connected to the supporting top plate; the transition groove is mounted on the supporting top plate.

[0009] Furthermore, in the aforementioned automatic transfer sealing mechanism for soup dispensing from the reverberatory furnace, at least two screws are provided on the support, and a first through hole is opened at each screw on the supporting top plate. Each screw passes upward through the corresponding first through hole, and a first nut is provided at the position of each screw below the supporting top plate.

[0010] Furthermore, in the aforementioned automatic transfer sealing mechanism for soup dispensing from the reverberatory furnace, a flange is provided at the bottom of the transition groove, and a second through hole is opened at each screw corresponding to the flange. Each screw passes upward through the corresponding second through hole, and a second nut is provided above the flange on each screw. Each screw is provided with a spring, with the top end of each spring abutting against the flange and the bottom end of each spring abutting against the supporting top plate.

[0011] Furthermore, in the aforementioned automatic transfer sealing mechanism for the reverberatory furnace soup dispensing mechanism, the worm gear lifting mechanism also includes a handwheel, which is connected to one end of the worm.

[0012] Beneficial Effects: This utility model provides an automatic transfer and sealing mechanism for soup dispensing in a reverberatory furnace. Compared with existing technologies, it features a first arc surface at the bottom of the soup outlet and a corresponding second arc surface at the inlet of the transition groove, with the axes of the two arc surfaces remaining parallel. When the reverberatory furnace rotates around its axis for soup dispensing, the transition groove maintains a close fit between the second and first arc surfaces, forming a continuous sealing surface along the length of the arc surface. This fundamentally solves the problem of aluminum dripping caused by misalignment of the sealing surface during furnace rotation. Furthermore, the addition of a composite sealing structure at the inlet of the transition groove, consisting of a first horizontal sealing groove, two sections of first vertical sealing grooves, and internal filler, further improves the sealing effect at the bottom and sides of the soup outlet.

[0026] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model is further described in detail below. It should be understood that the specific embodiments described herein are merely for explaining this utility model and are not intended to limit this utility model.

[0027] Please see Figures 1 to 10 This utility model provides an automatic transfer and sealing mechanism for the soup outlet of a reverberatory furnace. The accompanying drawings are for illustrative purposes only, highlighting only the structures relevant to the innovation; some conventional structures (such as the internal structure of a worm gear lifting mechanism) are not shown. The terms "first," "second," etc., used herein are merely different names for similar structures for ease of explanation and are not intended to limit this application. The axes of the aforementioned arc surfaces refer to the axis of the cylinder on which the arc surface lies.

[0028] Please refer to the following first. Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 9 The automatic transfer and sealing mechanism for discharging soup in the reverberatory oven includes a soup discharging pipe 1, a transition groove 2, and a transition groove lifting device 3. A first arc surface 41 is provided at the bottom of the outlet end of the soup discharging pipe, and a second arc surface 42 is provided at the inlet end of the transition groove 2. The second arc surface is located below the first arc surface, and the axis 420 of the second arc surface is parallel to the axis 410 of the first arc surface. The transition groove lifting device 3 is used to drive the transition groove to rise and fall. After the transition groove rises, the second arc surface can abut against the first arc surface (e.g., ...). Figure 7 (The state shown).

[0029] The transition groove includes a bottom plate 21 and two side plates 22 (e.g. Figure 10 (As shown). The aforementioned second arc surface is located at the inlet end of the bottom plate of the transition groove. Since the axis of the second arc surface is parallel to the axis of the first arc surface, when the second arc surface abuts against the first arc surface, the second arc surface and the first arc surface continuously fit together along the axial direction (i.e., the length direction of the first arc surface), thereby achieving a sealing effect.

[0030] For ease of understanding, the attached diagram shows the rotating shaft of the reverberatory furnace. The axis of the rotating shaft actually coincides with the axis of the first arc surface. When the reverberatory furnace rotates to dispense soup, the second arc surface and the first arc surface always remain in contact, thereby keeping the outlet end of the soup dispensing pipe and the inlet end of the transition groove in contact.

[0031] Please see Figure 10To further improve the sealing effect, the following improvements can be made: A first sealing groove is provided at the inlet end of the transition groove 2. This first sealing groove includes a first horizontal sealing groove 511 and two first vertical sealing grooves 512. The first horizontal sealing groove 511 is located below the soup outlet pipe; the two first vertical sealing grooves 512 are located on both sides of the soup outlet pipe 1; and packing 6 (attached) is provided in both the first horizontal sealing groove and the two first vertical sealing grooves. Figure 5 The packing material 6 is schematically shown. By setting the packing material in the first horizontal sealing groove, the sealing effect between the bottom of the soup outlet pipe and the transition groove is further improved. By setting the packing material in the two sections of the first vertical sealing groove, the sealing effect between the two vertical sides of the soup outlet pipe and the transition groove is improved.

[0032] In practical applications, a chute 8 is installed downstream of the transition channel to guide the molten aluminum to subsequent equipment. There are various connection methods between the transition channel and the chute. As a preferred option, a scheme similar to the combination of the first and second arc surfaces can also be used. For details, please refer to [link to relevant documentation]. Figure 8 The bottom of the outlet end of the transition trough is provided with a third arc surface 43, the axis 430 of which is parallel to the axis 420 of the second arc surface. Correspondingly, the bottom of the inlet end of the chute 8 is provided with a fourth arc surface 44, the axis 440 of which is parallel to the axis 430 of the third arc surface. The bottom of the chute is not higher than the bottom of the transition trough, so that the molten aluminum in the transition trough can flow normally into the chute. Since the chute itself is not within the protection scope of this utility model, the attached drawings only schematically show the front end of the chute 8, and this document does not specifically limit the structure of the chute.

[0033] Please see Figure 10 Furthermore, a second sealing groove is provided at the outlet end of the transition groove 2. This second sealing groove includes a second horizontal sealing groove 521 and two second vertical sealing grooves 522. Packing material is provided in both the second horizontal sealing groove and the two second vertical sealing grooves. By providing packing material in the second horizontal sealing groove, the sealing effect between the bottom of the chute inlet end and the transition groove is further improved. By providing packing material in the two second vertical sealing grooves, the sealing effect between the two vertical sides of the chute inlet end and the transition groove is improved.

[0034] Please see Figures 1 to 4The transition groove lifting device 3 includes a bracket 31, a worm gear lifting mechanism 32 mounted on the bracket, and a supporting top plate 33. The worm gear lifting mechanism 32 includes a housing 321, a worm, a worm wheel, and a lead screw 329, with the top end of the lead screw 329 connected to the supporting top plate 33. The transition groove is mounted on the supporting top plate. The lead screw is the output end of the worm gear lifting mechanism; the lifting of the lead screw can drive the lifting of the supporting top plate, thereby driving the lifting of the transition groove. Since the worm gear lifting mechanism itself is existing technology, its structural principle is clear to those skilled in the art; therefore, its detailed internal structure is not shown in the accompanying drawings.

[0035] Please continue reading. Figures 1 to 4 To further improve the stability of the supporting top plate, the bracket is further provided with at least two screws 34. A first through hole (not visible from the perspective of the attached drawing) is provided at each screw on the supporting top plate. Each screw passes upward through its corresponding first through hole. A first nut 351 is provided below each screw 34 located below the supporting top plate 33. The screws provide horizontal restraint for the supporting top plate, and the first nuts provide downward restraint.

[0036] like Figure 1 and Figure 10 As shown, furthermore, the bottom of the transition groove is provided with flanges 29 (only one flange 29 is visible from the perspective of the attached drawing, but there are actually two flanges 29, respectively provided on both sides of the bottom of the transition groove). Each flange 29 has a second through hole 290 corresponding to each screw 34. Each screw passes upward through the corresponding second through hole. A second nut 352 is provided above each screw on the flange. Each screw is equipped with a spring 36, with the top end of each spring 36 abutting against the flange 29 and the bottom end of each spring 36 abutting against the supporting top plate 33. As the transition groove rises until the second arc surface abuts against the first arc surface, the supporting top plate continues to rise a certain distance, compressing the springs and causing them to exert an upward force on the transition groove. This ensures that during actual use, the second arc surface always remains abutting against the first arc surface.

[0037] The worm gear lifting mechanism can be driven manually or electrically. Considering that the lifting mechanism does not need to be used frequently, it is preferable to drive it manually. That is, the worm gear lifting mechanism 32 also includes a handwheel 320, which is connected to one end of the worm.

[0038] In practical applications, the reverberatory furnace and chute are pre-installed. The gap between the soup tube and the chute is reserved according to the size of the transition trough. The automatic transfer sealing mechanism for the soup dispensing mechanism of the reverberatory furnace is set at the position corresponding to the soup dispensing pipe of the reverberatory furnace. The worm gear lifting device is adjusted to raise the transition trough to the position between the soup dispensing pipe and the chute. The worm gear lifting device is further adjusted so that the second arc surface abuts against the first arc surface, the third arc surface abuts against the fourth arc surface, and the spring is compressed. When the reverberatory furnace needs to pour out aluminum soup, its own drive device (e.g., a hydraulic cylinder, not shown in the figure) rotates the furnace body around an axis (e.g., a hydraulic cylinder). Figure 11 and Figure 12 As shown, after rotating a certain angle, the molten aluminum is poured from the outlet into the transition trough. The molten aluminum then flows through the transition trough to the chute and finally into the downstream equipment. After the molten aluminum is poured out, the reverberatory furnace's own drive mechanism resets the furnace body's reverse rotation mechanism. Because the axis of the rotating shaft coincides with the axis of the first arc surface, the second arc surface remains in contact with the first arc surface during the furnace's rotation, achieving a good sealing effect.

[0039] It should be noted that, due to the complex structure, large size, and fixed installation of the chute itself, a lifting device cannot be directly installed at the bottom of the chute to achieve the technical effect of this invention. This invention cleverly incorporates a transition groove and a corresponding lifting device between the soup outlet pipe and the chute, allowing the transition groove to be raised and lowered. A first arc surface is provided at the outlet end of the soup outlet pipe, and a second arc surface is provided at the inlet end of the transition groove, thereby solving the technical problem of poor sealing at the outlet end of the soup outlet pipe.

[0040] It should be noted that in practical applications, a cover plate 92 is installed corresponding to the soup outlet pipe (e.g., Figure 12 As shown, during normal operation of the reverberatory furnace, the cover plate covers the outlet pipe; when it is necessary to pour out the aluminum broth, the cover plate opens. Since the cover plate is not an innovative point of this utility model and is not within the protection scope of this utility model, this article will not specifically describe or limit the cover plate and the drive device of the cover plate.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. It is understood that those skilled in the art can make equivalent substitutions or modifications based on the technical solution and inventive concept of the present utility model, and all such modifications or substitutions should fall within the protection scope of the present utility model.
