Abstract
Description
Technical Field
[0001] This utility model relates to the field of alloy raw material technology, specifically to an acid pickling device for the production of non-ferrous metal alloys. Background Technology
[0002] In alloy production, some ores need to be pickled to remove the oxide layer, oil, or impurities on the surface of the ore or intermediate products due to the presence of surface impurities (such as iron oxide scale, oil stains, gangue minerals, etc.) or symbiotic minerals, thereby improving the purity of the raw materials. In subsequent processing, one or more other elements are added to form an alloy, which has unique properties such as low density, high specific strength, good electrical and thermal conductivity, and strong corrosion resistance.
[0003] After some of the alloys or forgings have been formed, sand, oxide scale or release agent may be generated on the surface. Pickling can remove impurities and reduce the impact on subsequent machining or surface treatment. The common pickling process for this type of alloy requires selecting a suitable pickling solution according to the material of the aluminum alloy, and then reducing the corrosion of non-ferrous alloy castings by controlling the time, temperature and concentration.
[0004] However, some non-ferrous alloy castings have complex structures and surfaces with deep holes, blind holes, and internal cavities. During placement and cleaning, cavitation shielding and insufficient solution exchange can easily occur, leading to a reduction in the cleaning efficiency of non-ferrous alloy castings. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an acid pickling device for non-ferrous metal alloy production, which reduces the cavitation shielding phenomenon that easily occurs when some complex non-ferrous alloy castings are placed in and cleaned, thus reducing cleaning efficiency.
[0006] The technical solution adopted by this utility model to solve the technical problem is: a pickling device for non-ferrous metal alloy production, comprising a frame, a variable frequency ultrasonic generator, and ultrasonic transducers. The variable frequency ultrasonic generator is connected in parallel to several ultrasonic transducers via wires. A receiving frame is provided on the upper side of each ultrasonic transducer. A horizontal plate is welded to the bottom end of the receiving frame. The upper end of the horizontal plate contacts a base plate. The horizontal plate is fixedly connected to the ultrasonic transducers by adhesive. A water outlet pipe is provided on one side of the bottom end of the base plate. The receiving frame contacts the inner wall of the frame. A U-shaped pad is fixedly connected inside the frame. Support rods are fixedly connected to the four sides of the upper end of the U-shaped pad. The support rods are movable. The upper side of the movable insertion receiving frame is contacted by a rubber ring, and the upper end of the rubber ring is contacted by an L-shaped clamping plate. One side of the L-shaped clamping plate extends to and contacts the inner wall of the receiving frame. The support rod is threadedly connected to a pressure ring on the upper side of the receiving frame. A sealing frame is hinged to one side of the frame. An electric push rod is fixedly connected to the side of the sealing frame away from the frame. A slider is fixedly connected to the output end of the electric push rod. A fixed frame is fixedly connected to the side of the slider near the receiving frame. A drive motor is fixedly connected to one side of the fixed frame. A bidirectional screw is fixedly connected to the output end of the drive motor. Clamping strips are threadedly connected to both sides of the bidirectional screw that are far apart from each other.
[0007] As a preferred technical solution of this utility model, an auxiliary rod is fixedly connected inside the sealing frame, and springs are sleeved on both sides of the auxiliary rod. By setting the auxiliary rod, the stability of the slider movement is increased.
[0008] As a preferred technical solution of this utility model, a gasket is fixedly connected to the side of the sealing frame away from the electric push rod, and one side of the gasket corresponds to the side wall of the frame. By setting the gasket, the collision and friction between the sealing frame and the frame can be reduced.
[0009] As a preferred technical solution of this utility model, an operation slot is provided on one side of the frame. The operation slot is rotatably connected to a baffle via a rotating shaft. By setting the operation slot and the baffle, it is easy to open the baffle and observe the equipment status.
[0010] As a preferred technical solution of this utility model, a U-shaped slot is provided on the bottom side of the receiving frame, and a U-shaped rubber pad is provided in the U-shaped slot. A U-shaped protrusion is fixedly connected to the bottom end of the base plate, and the U-shaped protrusion corresponds to the U-shaped slot. A card hole is provided on the upper end of the base plate, and the card hole is inserted into the bottom end of the L-shaped card plate. By setting the U-shaped slot to correspond to the U-shaped protrusion and the card hole to correspond to the L-shaped card plate, the base plate can be limited, so as to achieve the effect of easy removal of the base plate.
[0011] As a preferred technical solution of this utility model, a U-shaped slot is provided on the bottom side of the receiving frame, and open slots are provided on all four sides of the frame. A connecting plate is fixedly connected to the frame on the upper side of the open slot. A positioning rod is inserted into the upper end of the connecting plate. The positioning rod is threadedly connected to a limiting plate. A latch is provided on both sides of the limiting plate and the latch contacts the support rod.
[0012] This utility model has the following advantages:
[0013] (1) By setting a detachable base plate structure inside the receiving frame, and then setting an electric push rod on one side of the sealing frame that can make the casting to be pickled held on the clamping bar shake, the oscillation can reduce the shielding phenomenon of air holes on the casting to be pickled and improve the cleaning efficiency.
[0014] (2) By disassembling the four pressure rings, the L-shaped clamping plate can be detached, so that the L-shaped clamping plate no longer restricts the base plate, thereby achieving the effect of easy disassembly and replacement of the base plate. At the same time, a horizontal plate structure is set between the base plate and the ultrasonic transducer to avoid the ultrasonic transducer being directly glued to the base plate. Furthermore, the use of the U-shaped groove, U-shaped pad and U-shaped protrusion to seal the base plate with the receiving frame can provide the effect of receiving acidic solution during the pickling process.

[0020] The present invention will be further described below with reference to the accompanying drawings.
[0021] Please refer to the following: Figure 1-3 The pickling apparatus shown includes a frame 1, a variable frequency ultrasonic generator 2, and ultrasonic transducers 3. The variable frequency ultrasonic generator 2 connects several ultrasonic transducers 3 in parallel via wires. A receiving frame 4 is provided on the upper side of each ultrasonic transducer 3. The receiving frame 4 and the base plate 6 are made of corrosion-resistant material. A horizontal plate 5 is welded to the bottom end of the receiving frame 4. The ultrasonic transducers 3 act directly on the horizontal plate 5 and then synchronously transmit the ultrasonic waves to the base plate 6. The upper end of the horizontal plate 5 contacts the base plate 6. The horizontal plate 5 is fixedly connected to the ultrasonic transducers 3 by adhesive. A water outlet pipe 12 is provided on one side of the bottom end of the base plate 6. A manual control valve is installed on the side, which opens and closes the outlet pipe 12 by rotation. A drain hole is opened on the bottom side of the base plate 6. A connecting ring is installed on the base plate 6 at the drain hole. Then, a rotating sleeve is connected to the outlet pipe 12. The outlet pipe 12 is connected to the drain hole by the threaded connection between the sleeve and the connecting ring. This allows for easy disassembly of the base plate 6. The receiving frame 4 contacts the inner wall of the frame 1. A U-shaped pad 7 is fixedly connected inside the frame 1. Support rods 8 are fixedly connected to the four sides of the upper end of the U-shaped pad 7. The support rods 8 are movably inserted into the upper side of the receiving frame 4. A rubber ring 9 contacts the upper side of the receiving frame 4. An L-shaped clamping plate 10 contacts the upper end of the rubber ring 9. One side of the card plate 10 extends to and contacts the inner wall of the receiving frame 4. A pressure ring 11 is threaded onto the upper side of the receiving frame 4, and rotating the pressure ring 11 ensures a stable connection between the rubber ring 9 fitted on the support rod 8 and the L-shaped card plate 10 with the receiving frame 4. Simultaneously, a card hole 24 is inserted into one side of the L-shaped card plate 10, providing a limit for the bottom plate 6 and reducing the risk of dislocation during vibration. A sealing frame 13 is hinged to one side of the frame 1. A corrosion-resistant and abrasion-resistant sensor is installed on one side of the sealing frame 13 to monitor the pH value of acidic solutions, facilitating subsequent solution replacement. The sealing frame 13 is located away from the frame 1. An electric push rod 14 is fixedly connected to the side. The extension and retraction of the electric push rod 14 can move the slider 15. The output end of the electric push rod 14 is fixedly connected to the slider 15. A fixed frame 16 is fixedly connected to the side of the slider 15 near the receiving frame 4. A drive motor is fixedly connected to one side of the fixed frame 16. A protective sleeve is provided on the drive motor. The drive motor drives the bidirectional screw 17 to rotate, which can make the clamping strips 18 move relative to each other. The output end of the drive motor is fixedly connected to the bidirectional screw 17. The two sides of the bidirectional screw 17 that are far apart from each other are threaded with clamping strips 18. The clamping strips 18 are made of titanium metal to reduce the corrosion of the clamping strips 18 by acidic solutions.
[0022] An auxiliary rod 19 is fixedly connected inside the sealing frame 13. There are two auxiliary rods 19. Each auxiliary rod 19 is located on both sides of the slider 15 and is fitted with a spring. By setting the auxiliary rods 19 and the springs, the slider 15 is limited to move only in a straight line, which improves the stability of the movement of the fixed frame 16.
[0023] Among them, a shim 20 is fixedly connected to the side of the sealing frame 13 away from the electric push rod 14. One side of the shim 20 corresponds to the side wall of the frame 1. By setting the shim 20, the collision wear of rotating the sealing frame 13 is reduced.
[0024] The frame 1 has an operation slot 21 on one side. The operation slot 21 is rotatably connected to a baffle 22 via a rotating shaft. Opening the baffle 22 allows for maintenance of the internal structure of the frame 1.
[0025] The receiving frame 4 has a U-shaped groove 23 on its inner bottom side, and a U-shaped rubber pad is placed inside the U-shaped groove 23. The side curvature of the base plate 6 is consistent with the side curvature of the receiving frame 4. A U-shaped protrusion is fixedly connected to the bottom end of the base plate 6, and the U-shaped protrusion corresponds to the U-shaped groove 23. A locking hole 24 is opened at the upper end of the base plate 6, and the locking hole 24 is inserted into the bottom end of the L-shaped locking plate 10. By setting the U-shaped groove 23 on the bottom side of the receiving frame 4 in conjunction with the U-shaped protrusion on the bottom side of the base plate 6, and then placing the U-shaped rubber pad between the two, it is convenient to receive the solution. At the same time, the U-shaped protrusion, in conjunction with the U-shaped groove 23, the locking hole 24 and the L-shaped locking plate 10, can provide upper and lower limit of the base plate 6, and improve the effect of stabilizing and limiting the base plate 6.
[0026] The frame 1 has open slots on all four sides. A connecting plate 25 is fixedly connected to the upper side of the open slot. A positioning rod 26 is inserted into the upper end of the connecting plate 25. The positioning rod 26 is threaded to a limiting plate 27. The limiting plate 27 has a latch on both sides and the latch contacts the support rod 8. By setting the positioning rod 26 in conjunction with the limiting plate 27, one side of the limiting plate 27 can contact the support rod 8, thereby pressing the pressure ring 11 and reducing the vibration of the pressure ring 11 from dislodging from the support rod 8.
[0027] Working principle: Select a suitable acidic solution according to the material of the non-ferrous alloy metal, and then place the alloy to be pickled onto the bottom plate 6. At this time, the sealing frame 13 is closed, and then the drive motor is started, so that the bidirectional screw 17 and the clamping bar 18 move relative to each other and clamp the alloy metal to be pickled. Further, the electric push rod 14 extends and retracts, causing the slider 15 and the fixed frame 16 to move and vibrate the alloy to be pickled, thereby reducing the cavitation shielding phenomenon on the alloy. Then, the frequency conversion ultrasonic generator 2 is started, and then the ultrasonic transducer 3 vibrates and transmits it to the horizontal plate 5 and the bottom plate 6, causing the solution to vibrate and causing the sand, oxide scale or mold release agent or other impurities on the alloy to be pickled to be removed. After a period of time, the manual control valve can be opened to remove the acidic solution. Then, the limiting plate 27 and the pressure ring 11 are removed, which allows the L-shaped clamping plate 10 and the rubber ring 9 to be detached, so that the bottom plate 6 can be removed and replaced.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
