Description

Technical Field

[0001] This utility model relates to the technical field of aluminum liquid vortex well systems, and in particular to an impeller hanger for an aluminum liquid booster pump. Background Technology

[0002] The aluminum vortex well system is a key component of a dual-chamber aluminum furnace or a recycled aluminum smelting furnace. It is mainly used for the efficient and low-loss melting of scrap aluminum such as aluminum chips and scraps. Its core principle is to use the high-speed rotation of the impeller in the pump chamber to lift the aluminum liquid. The aluminum liquid enters the vortex well and flows from top to bottom along the side wall of the vortex well to form a vortex, which quickly immerses the scrap aluminum into the vortex molten pool, thus reducing oxidation loss.

[0003] In existing aluminum molten metal vortex well systems, the output shaft of the drive unit is coaxially connected to the impeller shaft in the pump chamber, driving the impeller shaft to rotate. The drive unit is supported above the pump chamber by a simple bracket. When impeller maintenance is required, an overhead crane is needed to detach the drive unit's base from the simple bracket and then hoist it to the maintenance site. Utility model patent CN202126169U discloses a side-well aluminum scrap melting furnace. This technical solution uses a bracket, lifting seat, lead screw, and reducer to lift the drive unit and impeller in place. While this lifting is convenient, it still requires an overhead crane in the workshop to move the impeller to the maintenance site. Utility Model Content

[0004] The purpose of this invention is to provide an impeller hanger for an aluminum liquid booster pump, which facilitates the lifting and moving of the impeller and reduces reliance on overhead cranes in the workshop.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model relates to an impeller hanger for an aluminum liquid booster pump, which is installed above the pump chamber of an aluminum liquid vortex well and is used to hoist the drive unit and impeller. It includes a support frame body, an electric hoist, a positioning seat, and a clamping block. The support frame body is a frame structure formed by bolted or welded steel sections. A guide rail beam is horizontally positioned at the top center of the support frame body, allowing the bottom wheels of the electric hoist to travel on the guide rail beam. A crossbeam support at the bottom of the support frame body spans between the pump chamber and an outer maintenance station. A sling at the bottom of the electric hoist connects to a hook at the top of the drive unit, enabling the drive unit and impeller to be moved between the pump chamber and the maintenance station. The positioning seat is horizontally positioned above the pump chamber on the crossbeam support at the bottom of the support frame body. The clamping block is mounted on the positioning seat, which positions the drive unit above the pump chamber, while the clamping block presses the drive unit against the positioning seat.

[0007] Furthermore, a drive support base plate is horizontally arranged at the bottom of the drive unit, and angle steel pieces are vertically arranged at the four corners of the drive support base plate. The angle steel pieces can cooperate with the positioning seat to position the impeller so that it accurately enters the pump chamber.

[0008] Furthermore, a positioning protrusion is provided in the center of the inward-facing side wall of the drive support base plate, and the positioning protrusion extends downward from the bottom surface of the drive support base plate; the positioning protrusion precisely positions the drive support base plate onto the positioning seat.

[0009] Furthermore, the positioning seat is a C-shaped plate component, and the opening of the positioning seat faces the maintenance station; positioning posts are vertically arranged at the four corners of the positioning seat, and the angle steel pieces are snapped onto the inner outer wall of the positioning posts.

[0010] Furthermore, the two inner positioning posts are higher than the two outer positioning posts.

[0011] Furthermore, a positioning slot is provided on the inner end plate of the positioning seat, and the positioning protrusion can be fitted into the positioning slot.

[0012] Furthermore, the top surfaces of the three side plates of the positioning seat are each equipped with two clamping blocks; the cross-section of the clamping block is L-shaped, and the middle part of the clamping block is installed into the threaded hole of the side plate of the positioning seat by screws.

[0013] Furthermore, the bottom crossbeam bracket of the main support frame is provided with four positioning columns at the maintenance station, and the positioning columns position the angle steel component.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0015] This utility model of an aluminum liquid booster pump impeller hanger, with its main support frame positioned above and to the side of the pump chamber, directly utilizes the outer end of the crossbeam bracket at the bottom of the support frame as a temporary fixed workstation for maintenance, facilitating rapid maintenance operations. Simultaneously, an electric hoist capable of linear movement is integrated into the top of the support frame for hoisting the drive unit and impeller, reducing reliance on overhead cranes in the production workshop. The positioning seat and clamping block enable rapid positioning of the impeller into the pump chamber. This utility model of an aluminum liquid booster pump impeller hanger facilitates the lifting, lowering, and moving of the impeller, reducing reliance on overhead cranes in the workshop.

[0016] Furthermore, the precise installation of the drive unit is achieved through the cooperation of the drive support base plate and the positioning seat. The positioning columns and angle steel pieces provide guidance and positioning during the hoisting and descent of the drive unit. The two higher inner positioning columns initially limit the inward movement of the two angle steel pieces on the drive support base plate, indicating that the electric hoist should move inward into position. The positioning slots and protrusions ensure the drive support base plate accurately falls onto the positioning seat. The clamping blocks allow for quick clamping and disassembly of the drive support base plate's edges, enabling rapid assembly and disassembly of the drive unit. The positioning seat is installed using mounting holes and a lower oblong hole, allowing for easy adjustment of its position, facilitating accurate insertion of the impeller below the positioned drive unit into the pump chamber for operation. Adding positioning columns at the maintenance station allows for rapid positioning of the drive support base plate hoisted to the maintenance station, ensuring that the impeller does not accidentally slip outward along the bottom crossbeam support of the main support frame during maintenance.

[0027] In one specific implementation, such as Figures 1-4 As shown, the impeller hanger of this utility model aluminum liquid booster pump is installed above the pump chamber 8 of the aluminum liquid vortex well, and is used to hoist the drive unit 3 and the impeller 7. In the prior art, the drive unit 3 generally includes a base frame and a motor and a reducer mounted on the base frame. The downward output shaft of the reducer is coaxially connected to the top of the impeller 7. The impeller hanger of this utility model aluminum liquid booster pump includes a support frame body 1, an electric hoist 2, a positioning seat 5, and a clamping block 6. The support frame body 1 is a frame structure formed by bolting or welding of steel profiles. A guide beam 101 is horizontally arranged at the top center of the support frame body 1, and the bottom wheel of the electric hoist 2 can travel on the guide beam 101. The guide beam 101 is generally made of I-beam steel and has sufficient support strength. A horizontal beam support is arranged at the bottom of the support frame body 1, spanning between the pump chamber 8 directly above and the maintenance station on the outside. The sling at the bottom of the electric hoist 2 connects to the hook at the top of the base frame of the drive unit 3, enabling the drive unit 3 and impeller 7 to be moved between the pump chamber 8 and the maintenance station. The positioning seat 5 is horizontally positioned above the pump chamber 8 on the bottom crossbeam support of the support frame body 1, and the clamping block 6 is mounted on the positioning seat 5. The positioning seat 5 positions the drive unit 3 directly above the pump chamber 8, at which point the impeller 7 below the drive unit 3 is coaxially inserted into the pump chamber 8, enabling the pumping of molten aluminum. The clamping block 6 presses the drive unit 3 onto the positioning seat 5, providing a quick and temporary fixation.

[0028] The support frame body 1 is positioned above and to one side of the pump chamber 8, with the outer end of the crossbeam bracket at the bottom of the support frame body 1 serving as a temporary fixed workstation for maintenance, facilitating rapid maintenance operations. Simultaneously, an electric hoist 2, capable of linear movement, is integrated into the top of the support frame body 1 to hoist the drive unit 3 and impeller 7, reducing reliance on overhead cranes in the production workshop. The positioning seat 5 and clamping block 6 enable rapid positioning of the impeller 7 into the pump chamber 8. This utility model of an aluminum liquid booster pump impeller hanger facilitates the lifting, lowering, and transfer of the impeller, reducing reliance on overhead cranes in the workshop.

[0029] In one specific embodiment of this utility model, such as Figure 1 and Figure 3 As shown, a drive support base plate 4 is horizontally mounted at the bottom of the drive unit 3, and the reducer of the drive unit 3 is fixed on the drive support base plate 4. Angle steel pieces 401 are vertically mounted at the four corners of the drive support base plate 4, and the angle steel pieces 401 can cooperate with the positioning seat 5 to position the impeller 7 accurately into the pump chamber 8. An output shaft through hole 403 for the output shaft of the reducer of the drive unit 3 is provided in the middle of the drive support base plate 4.

[0030] Specifically, such as Figure 3 As shown, a positioning protrusion 402 is centrally located on the inward-facing side wall of the drive support base plate 4, protruding downwards from the bottom surface of the drive support base plate 4. The positioning protrusion 402 precisely positions the drive support base plate 4 onto the positioning seat 5.

[0031] Specifically, such as Figure 1 and Figure 4 As shown, the positioning seat 5 is a C-shaped plate component. The positioning seat 5 is horizontally fixedly connected to the crossbeam bracket at the bottom of the support frame body 1, and the opening of the positioning seat 5 faces the maintenance station. Positioning posts 501 are vertically installed at the four corners of the positioning seat 5, and angle steel pieces 401 are snapped into the inner outer wall of the positioning posts 501.

[0032] Specifically, such as Figure 1 As shown, the two inner positioning posts 501 are higher than the two outer positioning posts 501. The positioning posts 501 are cylindrical components.

[0033] Specifically, such as Figure 1 As shown, a positioning slot 503 is provided on the inner end plate of the positioning seat 5, and the positioning protrusion 402 can be fitted into the positioning slot 503.

[0034] The drive unit 3 can be accurately installed in place by the cooperation of the drive support base plate 4 and the positioning seat 5; the positioning column 501 and the angle steel piece 401 can guide and position the drive unit 3 during the hoisting and descent process, and the two higher positioning columns 501 on the inner side initially limit the two angle steel pieces 401 facing inward on the drive support base plate 4, prompting the electric hoist 2 to move inward into place; the positioning slot 503 and the positioning protrusion 402 can accurately drop the drive support base plate 4 into the positioning seat 5.

[0035] In one specific embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the top surfaces of the three side plates of the positioning base 5 are each equipped with two clamping blocks 6, which are symmetrically arranged in the center. The cross-section of the clamping block 6 is L-shaped, and the middle part of the clamping block 6 is installed into the threaded hole of the side plate of the positioning base 5 by screws. The cantilever end of the clamping block 6 can be pressed against the drive support base plate 4.

[0036] By quickly pressing and disassembling the edge of the drive support base plate 4 with the clamping block 6, the drive unit 3 can be quickly assembled and disassembled.

[0037] In one specific embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the top surface of the side plate of the positioning seat 5 has a mounting hole 502. The mounting hole 502 is an oblong hole with its long side parallel to the length direction of the guide rail beam 101. Correspondingly, the crossbeam bracket at the bottom of the support frame body 1 also has an oblong hole, which is perpendicular to the long side of the mounting hole 502. The mounting bolts pass through the mounting hole 502 and the oblong hole below to install the positioning seat 5. Large round washers need to be stacked on both the top and bottom of the mounting bolts.

[0038] By using mounting holes 502 and lower oblong holes to install the positioning seat 5, the front, back, left and right positions of the positioning seat 5 can be easily adjusted, making it easy for the impeller 7 below the positioned drive unit 3 to be accurately inserted into the pump chamber 8 for operation.

[0039] In one specific embodiment of this utility model, such as Figure 1 As shown, the bottom crossbeam bracket of the support frame body 1 is equipped with four positioning columns 501 at the maintenance station, which are consistent with the positioning method at the positioning seat 5. The positioning columns 501 position the angle steel piece 401.

[0040] By adding a positioning column 501 to the maintenance station, the drive support base plate 4 hoisted to the maintenance station can be quickly positioned, ensuring that the impeller 7 will not accidentally slide outward along the bottom crossbeam bracket of the support frame body 1 during the maintenance process.

[0041] The process of using this utility model aluminum liquid lifting pump impeller hanger is as follows: After completing the maintenance of the impeller 7 located at the maintenance station, the electric hoist 2 is used with a remote control to lift and pull the vertically lifting drive unit 3 and impeller 7. The drive support base plate 4 is released from the restriction of the positioning column 501 at the maintenance station, and then the electric hoist 2 is controlled to move inward along the guide rail beam 101. When the angle steel piece 401 on the inner side of the drive support base plate 4 contacts the two higher positioning columns 501, the electric hoist 2 is controlled to descend. The descent is slow, so that the four angle steel pieces 401 are respectively engaged with the inner outer wall of the positioning column 501. When the drive support base plate 4 is about to descend onto the positioning seat 5, the positioning protrusion 402 can be engaged and embedded into the positioning slot 503 to complete the final positioning. At this time, the impeller 7 below the drive unit 3 is accurately inserted into the pump chamber 8. After the drive support base plate 4 is placed on the positioning seat 5, the edge of the drive support base plate 4 is pressed with the clamping block 6, and the screw in the middle is tightened so that the cantilever end of the clamping block 6 can be pressed onto the drive support base plate 4. The motor of the drive unit 3 is turned on, the motor drives the reducer, and the reducer drives the impeller to rotate in the pump chamber 8 to pump and lift the aluminum liquid.

[0042] In summary, this utility model of an aluminum liquid booster pump impeller hanger, with the support frame body 1 positioned above and to one side of the pump chamber 8, directly uses the outer end of the crossbeam bracket at the bottom of the support frame body 1 as a temporary fixed workstation for maintenance, facilitating rapid maintenance operations. Simultaneously, by integrating a linearly moving electric hoist 2 at the top of the support frame body 1 to hoist the drive unit 3 and impeller 7, reliance on overhead cranes in the production workshop is reduced. The positioning seat 5 and clamping block 6 enable rapid positioning of the impeller 7 into the pump chamber 8. This utility model of an aluminum liquid booster pump impeller hanger facilitates the lifting, lowering, and transfer of the impeller, reducing reliance on overhead cranes in the workshop. Furthermore, the drive support base plate 4 and the positioning seat 5 work together to ensure accurate installation of the drive unit 3. The positioning column 501 and the angle steel piece 401 work together to guide and position the drive unit 3 during hoisting and descent. The two higher inner positioning columns 501 initially limit the inward movement of the two angle steel pieces 401 on the drive support base plate 4, indicating that the electric hoist 2 should move inward into position. The positioning slot 503 and the positioning protrusion 402 work together to ensure the drive support base plate 4 accurately falls onto the positioning seat 5. The clamping block 6 quickly clamps and disassembles the edge of the drive support base plate 4, enabling rapid assembly and disassembly of the drive unit 3. The positioning seat 5 is installed using the mounting hole 502 and the lower oblong hole, allowing for easy adjustment of its position (front, back, left, right), facilitating accurate insertion of the impeller 7 below the positioned drive unit 3 into the pump chamber 8 for operation. By adding a positioning column 501 to the maintenance station, the drive support base plate 4 hoisted to the maintenance station can be quickly positioned, ensuring that the impeller 7 will not accidentally slide outward along the bottom crossbeam bracket of the support frame body 1 during the maintenance process.
