Description

Technical Field

[0001] The present application belongs to the technical field of high-purity aluminum preparation, and specifically relates to a high-purity aluminum cleaning device. Background Art

[0002] High-purity aluminum has excellent electrical and thermal conductivity, reflectivity, ductility, and corrosion resistance, and is widely used in aerospace, energy, transportation, semiconductors, and other fields. The production of high-purity aluminum and ultra-high-purity aluminum with a purity of 5N (99.999%) and above has extremely strict requirements on raw materials. The raw material must be at least 3N5 (99.95%) refined aluminum (such as electrolytic aluminum or secondary refined aluminum). If ultra-high-purity aluminum of 6N and above is produced, 4N-5N aluminum must be used as the initial raw material. After mechanical processing, these raw aluminum materials will form a dense aluminum oxide film on the surface, and a large amount of impurities such as cutting fluid and dust will adhere to them. Direct use will affect the purity of the high-purity aluminum products.

[0003] Pickling is an effective method for removing residual impurities and metal oxides from the surface of aluminum ingots and is an essential process for processing aluminum raw materials used in high-purity aluminum production. Traditionally, the pickling method involves immersing the metal parts in a pickling tank, allowing them to sit for a while, then removing them from the tank and transferring them to a cleaning tank to clean any residual acid from the surface. This method is slow, time-consuming, inefficient, and complex, resulting in low acid solution utilization. Furthermore, the operator is required to manually and closely contact the acid solution, which is highly dangerous. Summary of the Invention

[0055] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0056] The high-purity aluminum cleaning device provided in this embodiment is intended to at least to some extent solve the technical problems of low efficiency and high risk in cleaning residual impurities and metal oxides on the surface of high-purity aluminum.

[0057] Figure 1 Schematic diagram of the structure of a high-purity aluminum cleaning device according to some embodiments; Figure 2 for Figure 1 Side view of the medium and high purity aluminum cleaning device; Figure 3 for Figure 1 A top view of the support platform of the high-purity aluminum cleaning device. Figure 1 、 Figure 2 and Figure 3 The high-purity aluminum cleaning device of the embodiment of the present application includes: a housing 10, a support platform 20, a support assembly 70, a hanging assembly 80, and a raw material rack 90. The support platform 20 is arranged in the housing 10, and an ethanol washing tank 30, an acid washing tank 40, a water washing tank 50, and a drying tank 60 are arranged in parallel and spaced apart on the support platform 20. The support assembly 70 is arranged in the housing 10 and is located above the support platform 20. The hanging assembly 80 is slidably mounted on the support assembly 70. The raw material rack 90 is detachably connected to the hanging assembly 80.

[0058] The ethanol washing tank 30 , the acid washing tank 40 , the water washing tank 50 and the drying tank 60 are all located below the support platform 20 .

[0059] Since the support platform 20 is arranged in the shell 10, the ethanol washing tank 30, the pickling tank 40, the water washing tank 50 and the drying tank 60 are arranged in parallel and spaced apart on the support platform 20, the support assembly 70 is arranged in the shell 10 and is located above the support platform 20, the hanging assembly 80 is slidably arranged on the support assembly 70, and the raw material rack 90 is detachably connected to the hanging assembly 80. Therefore, when it is necessary to clean the impurities and metal oxides on the surface of the high-purity aluminum, the high-purity aluminum is placed in the raw material rack 90, and the hanging assembly 80 is connected to the raw material rack 90. The hoisting assembly 80 slides on the supporting assembly 70 so that the raw material rack 90 reaches above the ethanol washing tank 30. The hoisting assembly 80 lowers the raw material rack 90 into the ethanol washing tank 30 to clean the surface of the high-purity aluminum. After the high-purity aluminum is cleaned in the ethanol washing tank 30, the hoisting assembly 80 lifts the raw material rack 90 out of the ethanol washing tank 30 and slides on the supporting assembly 70 so that the raw material rack 90 reaches above the pickling tank 40. The hoisting assembly 80 lowers the raw material rack 90 into the pickling tank 40 to clean the high-purity aluminum. After the high-purity aluminum is cleaned in the pickling tank 40, the hoisting assembly 80 lifts the raw material rack 90 out of the pickling tank 40 and slides on the support assembly 70 so that the raw material rack 90 reaches the top of the water washing tank 50. The hoisting assembly 80 lowers the raw material rack 90 into the water tank to achieve cleaning of the high-purity aluminum surface. After the high-purity aluminum is cleaned in the water washing tank 50, the hoisting assembly 80 lifts the raw material rack 90 out of the water washing tank 50 and slides on the support assembly 70 so that the raw material rack 90 reaches the drying tank 6. 0, the hoisting assembly 80 lowers the raw material rack 90 into the drying tank 60 to dry the surface of the high-purity aluminum. After the high-purity aluminum is dried in the drying tank 60, the hoisting assembly 80 lifts the raw material rack 90 out of the drying tank 60 and places the raw material rack 90 on the transportation equipment to transport the cleaned high-purity aluminum out of the shell 10. This can achieve continuous and automatic cleaning of the high-purity aluminum, save manpower, reduce labor intensity, improve cleaning efficiency, and prevent operators from being exposed to highly corrosive acid for a long time and causing physical harm.

[0060] After the hoisting assembly 80 lowers the raw material rack 90 into the pickling tank 40, the hoisting assembly 80 can send the next raw material rack 90 into the ethanol washing tank 30 to clean the high-purity aluminum on multiple raw material racks 90, further improving the cleaning efficiency.

[0061] The support platform 20 may be made of a high-strength, corrosion-resistant plastic material or a metal-based material covered with plastic.

[0062] The material of the ethanol washing tank 30 can be a high-strength and corrosion-resistant plastic material or a metal base with a plastic or metal outer layer.

[0063] The pickling tank 40 may be made of a high-strength, corrosion-resistant plastic material or a metal base covered with a plastic material.

[0064] The material of the water washing tank 50 can be a high-strength and corrosion-resistant plastic material or a metal base covered with a plastic material.

[0065] The drying tank 60 may be made of metal.

[0066] The acid solution in the pickling tank 40 is HF or a mixture of HF and HNO3, with a concentration of 1%-12%, and the pickling time is 5-30 minutes.

[0067] In some embodiments, the shell 10 is made of high-strength, corrosion-resistant plastic material or a material with metal as the base and plastic as the outer cover. The shell 10 is divided into a first part and a second part by the support platform 20. The first part is located below the second part. The ethanol washing tank 30, the pickling tank 40, the water washing tank 50 and the drying tank 60 are all arranged in the first part. A sliding transparent window is provided on one side of the second part for easy observation. At the same time, it can prevent acid from splashing and injuring the operator, thereby ensuring the safety of the operator.

[0068] Figure 4 for Figure 1 Schematic diagram of the structure of the support assembly of the medium and high purity aluminum cleaning device. Figure 1 、 Figure 2 and Figure 4 In some embodiments, to enable the suspension assembly 80 to slide on the support assembly 70, the support assembly 70 includes a first driver 71 and a lead screw 72. The first driver 71 is disposed in the housing 10. The lead screw 72 is rotatably disposed within the housing 10 and is connected to the first driver 71. The lead screw 72 is threadably connected to the suspension assembly 80. The driver 71 may be a motor.

[0069] When the hoisting assembly 80 is to be moved, the first driver 71 is started, the action end of the first driver 71 drives the screw rod 72 to rotate, and the screw rod 72 drives the hoisting assembly 80 to move.

[0070] Combine Figure 4 In some embodiments, in order to enable the hanging assembly 80 to slide on the support assembly 70, the support assembly 70 further includes a support rod 73. The support rod 73 is disposed in the housing 10 and is spaced apart from the lead screw 72. The support rod 73 is parallel to the lead screw 72. One end of the hanging assembly 80 is threadedly connected to the lead screw 72, and the other end is slidably disposed on the support rod 73. The support rod 73 restricts the hanging assembly 80 so that when the lead screw 72 rotates, the hanging assembly 80 can be driven to move along the length direction of the lead screw 72 without rotating.

[0071] Combine Figure 1In some embodiments, the support assembly 70 further includes a limiter 74 . The limiter 74 is disposed on the screw rod 72 , and the drying tank 60 is located between the limiter 74 and the ethanol washing tank 30 . When the hoisting assembly 80 moves to the limiter 74 , the limiter 74 is triggered, and the limiter 74 sends a stop signal to the first driver 71 to prevent excessive movement of the hoisting assembly 80 . The limiter 74 may be a limit switch.

[0072] Combine Figure 1 and Figure 4 In some embodiments, to enable the lifting assembly 80 to lift the raw material rack 90, the lifting assembly 80 includes: a first connecting member 81, a second connecting member 82, a second driver, a lifting rope 83, and a gripper 84. The first connecting member 81 is threadedly connected to the lead screw 72 and moves in a first direction. The second connecting member 82 is slidably mounted on the first connecting member 81 and moves in a second direction. The second driver is mounted on the second connecting member 82. The lifting rope 83 is connected to the second driver. The gripper 84 is connected to the lifting rope 83 and is detachably connected to the raw material rack 90. The ethanol washing tank 30, the pickling tank 40, the water washing tank 50, and the drying tank 60 are arranged in parallel and spaced apart along a first direction, on the same horizontal plane, with the first direction being perpendicular to the second direction. The first direction can be the length of the lead screw 72. The gripper 84 can be a pneumatic gripper or an electric gripper.

[0073] When the raw material rack 90 is to be hoisted, the second driver is activated. The action end of the second driver drives the gripper 84 downward via the lifting rope 83. The gripper 84 grabs the raw material rack 90 to achieve connection with the raw material rack 90. The second driver is then activated to drive the raw material rack 90 upward via the lifting rope 83 and the gripper 84. The first driver 71 is activated. The first driver 71 drives the first connecting member 81 to move in the first direction via the screw rod 72, so that the raw material rack 90 reaches above one of the ethanol washing tank 30, the pickling tank 40, the water washing tank 50, and the drying tank 60. The second driver is then activated. The action end of the second driver drives the gripper 84 downward via the lifting rope 83. The gripper 84 releases the raw material rack 90 to achieve separation from the raw material rack 90, so that the raw material rack 90 falls into one of the ethanol washing tank 30, the pickling tank 40, the water washing tank 50, and the drying tank 60.

[0074] When the raw material rack 90 reaches above one of the ethanol washing tank 30, the pickling tank 40, the water washing tank 50 and the drying tank 60, the second connecting member 82 slides on the first connecting member 81, and in the second direction, the second connecting member 82 drives the second driver to move, and the second driver drives the raw material rack 90 to move through the hanging rope 83 and the gripper 84, so that the raw material rack 90 is aligned with the top of the opening of one of the ethanol washing tank 30, the pickling tank 40, the water washing tank 50 and the drying tank 60, and the raw material rack 90 can smoothly enter one of the ethanol washing tank 30, the pickling tank 40, the water washing tank 50 and the drying tank 60.

[0075] In some embodiments, there are two first connecting members 81 , which are spaced apart and arranged side by side, and both ends of the second connecting member 82 can be slidably mounted on the two first connecting members 81 .

[0076] In some embodiments, the hoisting assembly 80 further includes a third driver. The fixed end of the third driver is connected to the first connector 81. The operating end of the third driver is provided with a running wheel. The first connector 81 is provided with a track, and the running wheel is located within the track. When the second connector 82 is required to move in the second direction, the third driver is activated, and the operating end of the third driver drives the running wheel to move within the track, thereby causing the second connector 82 to move in the second direction. The third driver may be a motor.

[0077] Of course, in other embodiments, the hoisting assembly 80 further includes a pusher. The pusher's fixed end is attached to the first connecting member 81, and its actuating end is connected to the second connecting member 82. The second connecting member 82 is provided with a slider, and the first connecting member 81 is provided with a track within which the slider is slidably mounted. When the second connecting member 82 is required to move in the second direction, the pusher is activated, and the actuating end of the pusher pushes the second connecting member 82, causing the slider to move within the track, thereby moving the second connecting member 82 in the second direction. The pusher may be a pneumatic cylinder.

[0078] Combine Figure 1 In some embodiments, the housing 10 is provided with an operation panel 240, which can be used to set the number of raw material racks 90. The operation panel 240 can be used to set the cleaning liquid volume and cleaning time of the ethanol washing tank 30, and the jet flow rate and jet speed of the air nozzle group 100 in the ethanol washing tank 30. The operation panel 240 can be used to set the acid concentration injected into the pickling tank 40, the acid concentration required for cleaning, the cleaning liquid volume and cleaning time of the pickling tank, and the jet flow rate and jet speed of the air nozzle group 100 in the pickling tank 40. The operation panel 240 can be used to set the pure water volume and cleaning time of the water washing tank 50, and the jet flow rate and jet speed of the air nozzle group 100 in the pickling tank 50. The operation panel 240 can also be used to set the drying temperature and drying time of the drying tank 60.

[0079] In some embodiments, the second driver may be a winch, and one end of the suspension rope 83 is wound around the action end of the winch.

[0080] In some embodiments, the number of second drivers, lifting ropes 83 and grippers 84 can be multiple, multiple second drivers correspond one-to-one to multiple lifting ropes 83, and multiple lifting ropes 83 correspond one-to-one to multiple grippers 84. One end of the lifting rope 83 is connected to the corresponding second driver, and the other end is connected to the corresponding gripper 84, so as to realize that the lifting assembly 80 and the raw material rack 90 have multiple connection points, thereby realizing the stability of the lifting raw material rack 90.

[0081] In some embodiments, one end of the first connector 81 is threadedly connected to the lead screw 72, and the other end is slidably mounted on the support rod 73. A nut is provided at the end of the first connector 81, which is threadedly connected to the lead screw 72. A sleeve is provided at the end of the first connector 81, which is sleeved on the support rod 73 to enable the end of the first connector 81 to slide on the support rod 73.

[0082] Combine Figure 2 In some embodiments, to support high-purity aluminum, the raw material rack 90 includes: a base 91, a raw material frame 92, a central shaft 93, and a lifting lug 94. At least one raw material frame 92 is used to support high-purity aluminum. The central shaft 93 is connected to the base 91 and passes through the at least one raw material frame 92. The lifting lug 94 is provided on the raw material frame farthest from the base 91 among the at least one raw material frame 90 and is detachably connected to the lifting assembly 80. The lifting lug 94 is detachably connected to the gripper 84 of the lifting assembly 80. The number of lifting lugs 94 can be multiple, and the number of grippers 84 can be multiple. The multiple lifting lugs 94 correspond one-to-one to the multiple grippers 84, and the lifting lugs 94 are detachably connected to the corresponding grippers 84.

[0083] A central shaft 93 is connected to the base 91 and supported by the base 91. The central shaft 93 is passed through at least one raw material frame 92 to limit the position of the raw material frame 92 and ensure the stability of the raw material frame 92 installed on the base 91. High-purity aluminum is placed in the raw material frame 92 to support the high-purity aluminum. The lifting assembly 80 is connected to the lifting lug 94 to lift the raw material frame 92.

[0084] In some embodiments, when there are multiple raw material frames 92, a supporting member is provided between two adjacent raw material frames 92, and the supporting member 95 is detachably connected to the central axis 93. The upper raw material frame 92 of the two adjacent raw material frames 92 is supported by the supporting member 95 to achieve the spacing of the two adjacent raw material frames 92, so that the high-purity aluminum in the raw material frame 92 is fully exposed, to ensure that the high-purity aluminum in the raw material frame 92 can fully react with the ethanol in the ethanol washing tank 30 and the acid in the pickling tank 40, and also enable the water in the water washing tank 50 to fully clean the high-purity aluminum, and the drying tank 60 can fully dry the high-purity aluminum.

[0085] In some embodiments, the height of the raw material basket 92 can be adjusted by adjusting the position of the carrier 95 on the central axis 93, thereby meeting the placement requirements of high-purity aluminum blocks of different shapes and sizes and having a wide range of applications. The carrier 95 can be a nut.

[0086] In some embodiments, the raw material rack 90 further includes a locking member. The locking member is detachably connected to the end of the central shaft 93 facing away from the base 91. When the raw material rack 92 is to be installed, the locking member is removed from the central shaft 93. After the raw material rack 92 is installed, the locking member is installed back to the end of the central shaft 93 facing away from the base 91. This prevents the raw material rack 92 from being detached from the central shaft 93 and ensures the stability of the installation of the raw material rack 92. The locking member may be a nut.

[0087] Combine Figure 1 、 Figure 2 and Figure 3 In some embodiments, in order to fully clean the high-purity aluminum, at least one air nozzle group 100 is provided in the ethanol washing tank 30, the pickling tank 40 and the water washing tank 50. When the raw material rack 90 enters the ethanol washing tank 30, the pickling tank 40 and the water washing tank 50, the air nozzle group 100 is started, and the air nozzle group 100 sprays gas to form a vortex in the ethanol washing tank 30, the pickling tank 40 and the water washing tank 50, thereby washing away surface impurities of the high-purity aluminum block.

[0088] After the high-purity aluminum block is cleaned in the ethanol washing tank 30, the acid washing tank 40 and the water washing tank 50, the air nozzle group 100 can continue to spray gas to quickly dry the liquid on the surface of the raw material rack 90 and the high-purity aluminum block to prevent liquid dripping from damaging the operating table and contaminating the cleaning liquid used in the next cleaning process.

[0089] In some embodiments, in order to ensure that vortexes are formed in the ethanol washing tank 30, the pickling tank 40 and the water washing tank 50, the air nozzle group 100 is composed of a plurality of air nozzles 101 evenly spaced at equal angles. The angles between the axis of the air nozzle 101 and the tangent of the inner wall of the ethanol washing tank 30, the pickling tank 40 and the water washing tank 50 are all 30°-60°, and the angles between the axis of the air nozzle 101 and the axis of the tank body of the ethanol washing tank 30, the pickling tank 40 and the water washing tank 50 are all 50°-80°. The jet speed of the air nozzle 101 is 5-15m / s, and the flow rate is 0.5-3m 3 / h.

[0090] In some embodiments, the number of the air nozzle groups 100 may be one or more. When the number of the air nozzle groups 100 is multiple, the multiple air nozzle groups 100 in the ethanol washing tank 30 are arranged at intervals along the axial direction of the ethanol washing tank 30, the multiple air nozzle groups 100 in the pickling tank 40 are arranged at intervals along the axial direction of the pickling tank 40, and the multiple air nozzle groups 100 in the water washing tank 50 are arranged at intervals along the axial direction of the water washing tank 50.

[0091] In some embodiments, the gas ejected by the air nozzle 101 is compressed air at room temperature.

[0092] In some embodiments, to ensure the stability of the raw material rack 90 when installed in the ethanol washing tank 30, the pickling tank 40, and the water washing tank 50, a stopper 110 is provided on the bottom wall of each of the ethanol washing tank 30, the pickling tank 40, and the water washing tank 50, and the raw material rack 90 is provided with a mounting hole 96. The stopper 110 is inserted into the mounting hole 96. The interaction between the stopper 110 and the wall of the mounting hole 96 prevents the raw material rack 90 from tipping over in the ethanol washing tank 30, the pickling tank 40, and the water washing tank 50, thereby ensuring the normal progress of the cleaning operation.

[0093] In some embodiments, the limiting member 110 may be conical or frustum-shaped to facilitate insertion of the limiting member 110 into the mounting hole 96 .

[0094] Combine Figure 1 and Figure 2 In some embodiments, to enable ethanol cleaning of high-purity aluminum, a first liquid outlet is defined at the bottom of the ethanol washing tank 30. The high-purity aluminum cleaning apparatus further includes an ethanol barrel 120, a first connecting pipe 130, a first valve 140, a first filter element 150, a second valve 260, a second connecting pipe 170, an ethanol circulation barrel 180, and a first bidirectional pump 190. The ethanol barrel 120 is disposed within the housing 10, above the ethanol washing tank 30. The ethanol barrel and the ethanol washing tank 30 are located on opposite sides of the support platform 20, respectively. The first connecting pipe 130 connects the ethanol barrel 120 and the ethanol washing tank 30. The first valve 140 is disposed in the first connecting pipe 130. The first filter element 150 is disposed at the bottom of the ethanol washing tank 30 and is connected to the first liquid outlet. The second valve 260 is disposed at the first liquid outlet. The second connecting pipe 170 is connected to the first filter element 150. The ethanol circulation barrel 180 is connected to the second connecting pipe 170. The first bidirectional pump 190 is disposed in the second communication pipe 170 .

[0095] When the high-purity aluminum is to be cleaned with ethanol, the first valve 140 is opened, and the ethanol in the ethanol barrel 120 flows, under the action of gravity, through the first connecting pipe 130 into the ethanol washing tank 30. The raw material rack 90 carries the high-purity aluminum into the ethanol washing tank 30 for cleaning. After the high-purity aluminum is cleaned in the ethanol washing tank 30, the second valve 260 is opened, and the first two-way pump 190 is started, allowing the ethanol in the ethanol washing tank 30 to enter the ethanol circulation barrel 180 through the first liquid outlet, the first filter element 150, and the second connecting pipe 170. The first filter element 150 filters the ethanol. After the raw material rack 90 is lifted out of the ethanol washing tank 30, the first two-way pump 190 is started, and the ethanol in the ethanol circulation barrel 180 can enter the ethanol washing tank 30 through the second connecting pipe 170, the first filter element 150, and the first liquid outlet, thereby recycling the ethanol.

The third connecting pipe is connected to the second filter element. The acid circulation tank is connected to the third connecting pipe. A second bidirectional pump is disposed in the third connecting pipe.

[0097] After the high-purity aluminum is cleaned in the pickling tank 40, the third valve is opened and the second two-way pump is started, allowing the ethanol in the pickling tank 40 to enter the acid circulation barrel through the second liquid outlet, the second filter element 200, and the third connecting pipe. The second filter element 200 can filter the ethanol. After the raw material rack 90 is lifted out of the pickling tank 40, the second two-way pump is started, and the ethanol in the acid circulation barrel can enter the pickling tank 40 through the third connecting pipe, the second filter element 200, and the second liquid outlet, thereby achieving acid recycling.

[0098] In some embodiments, the first filter element 150 and the second filter element 200 may be multi-stage bidirectional filters resistant to hydrofluoric acid corrosion, which can automatically peel off and flush attached impurities.

[0099] Combine Figure 2In some embodiments, to collect used ethanol, acid, and water, the high-purity aluminum cleaning apparatus further includes: a fourth connecting pipe 210, a fifth connecting pipe, a sixth connecting pipe, and a waste liquid bucket 220.

The sixth connecting pipe is connected to the bottom of the water washing tank 50. The waste liquid bucket 220 is connected to the fourth connecting pipe, the fifth connecting pipe, and the sixth connecting pipe. A one-way pump 230 is provided on each of the fourth connecting pipe 210, the fifth connecting pipe, and the sixth connecting pipe.

[0100] When the ethanol in the ethanol washing tank 30 reaches its service life, the one-way pump 230 on the fourth connecting pipe 210 is started to allow the ethanol in the ethanol washing tank 30 to enter the waste liquid barrel 220 through the fourth connecting pipe 210, and the used ethanol is collected by the waste liquid barrel 220 to ensure the safety of the staff.

[0101] When the acid in the pickling tank 40 reaches its service life, the one-way pump on the fifth connecting pipe is started to allow the acid in the pickling tank 40 to enter the waste liquid barrel 220 through the fifth connecting pipe, and the used acid is collected by the waste liquid barrel 220 to ensure the safety of the staff.

[0102] When the water in the washing tank 50 reaches its service life, the one-way pump on the fifth connecting pipe is started to allow the water in the washing tank 50 to flow into the waste liquid barrel 220 through the fifth connecting pipe, and the used water is collected by the waste liquid barrel 220 to ensure the safety of the staff.

[0103] The fourth communication pipe 210 , the fifth communication pipe and the sixth communication pipe are each provided with a fourth valve 160 to control the opening and closing of the fourth communication pipe 210 , the fifth communication pipe and the sixth communication pipe.

[0104] In some embodiments, the infrared heating lamps uniformly arranged within drying tank 60 have high heating efficiency, strong heat collection capacity, and high heat utilization rate, uniformly heating the high-purity aluminum and rapidly drying it.
