DETAILED DESCRIPTION

[0018] It is easy to understand that, according to the technical scheme of the present application, those skilled in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the present application. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical scheme of the present application, and should not be regarded as the whole or as the limitation or restriction of the technical scheme of the present application.

[0019] Example one, please refer toFigures 1 to 7 The application provides an ultrasonic-assisted high-pressure spray cleaning device for neodymium iron boron waste regeneration, which comprises a device outer box 1, an ultrasonic cleaner 2, a rotary cleaning cabin, a lifting material bearing mechanism, a central spray assembly and a centrifugal lifting mechanism.

[0020] The device outer box 1 is an external support and protection structure of the whole device, and an internal space is used for accommodating core components of the cleaning device.

[0021] The ultrasonic cleaner 2 is arranged below the inside of the device outer box 1; the ultrasonic cleaner 2 is used for deep cleaning of the waste material after preliminary cleaning by high-pressure spray, and through cavitation effect of ultrasonic waves, stubborn dirt and oxidation layers in the waste material surface and gaps are effectively removed, and cleaning thoroughness is improved.

[0022] The rotary cleaning cabin is rotationally arranged in the inside of the device outer box 1 and located above the ultrasonic cleaner 2; the rotary cleaning cabin comprises a rotating disc 3, an outer frame 5 rotationally driven by the rotating disc 3 through a connecting rod 4 and an outer protective net 6 arranged at the outer edge of the outer frame 5; the rotating disc 3 transmits rotary power to the outer frame 5 and the outer protective net 6 through the connecting rod 4, so that the outer frame 5 and the outer protective net 6 rotate synchronously; the outer protective net 6 is used for preventing the waste material from being thrown out during rotation; an upper inner edge 7 and a lower inner edge 8 are arranged on the inner side of the outer frame 5 in an annular shape; the two inner edges play a limiting and guiding role during lifting and discharging of the waste material.

[0023] The lifting material bearing mechanism is movably arranged below the rotating disc 3 and in the middle of the outer frame 5; the mechanism is used for bearing the waste material to be cleaned and can realize lifting during cleaning; the mechanism comprises an inner frame 9, an inner protective net 10 arranged at the outer edge of the inner frame 9 and a platform 11 fixed to the top of the inner frame 9; the inner protective net 10 and the outer protective net 6 jointly form an annular cleaning space to prevent the waste material from scattering during cleaning; the platform 11 is a component for initially bearing the waste material; the outer frame 5, the outer protective net 6, the upper inner edge 7, the lower inner edge 8, the inner frame 9 and the inner protective net 10 jointly enclose an annular cleaning space for accommodating the waste material to be cleaned.

[0024] The central spray assembly is used for high-pressure spray cleaning of the waste material; the central spray assembly comprises a flow divider 12 located at the bottom of the platform 11, spray pipes 13 radially distributed outside the flow divider 12 and having nozzles facing the inner protective net 10 and a connecting pipe 14 fixedly connected to the top of the flow divider 12 and penetrating the rotating disc 3 upwardly; the connecting pipe 14 is in sliding connection with the rotating disc 3, so that the central spray assembly can keep connection with an external water supply system while rotating and lifting; the nozzles of the spray pipes 13 face the inner protective net 10, so that high-pressure water flow can be uniformly sprayed onto the waste material in the annular cleaning space.

[0025] Centrifugal lifting mechanism: arranged inside and below the rotating disc 3; comprising radially distributed sliding grooves 23, counterweights 25 slidingly connected in the sliding grooves 23, upper rotating members 27 fixedly connected to the bottom of the counterweights 25, lower connecting members 29 fixedly connected to the top of the platform 11, and movable rods 28 movably connected between the upper rotating members 27 and the lower connecting members 29.

[0026] Working principle: When the rotating disc 3 rotates, the outer frame 5 and the outer protective net 6 are driven to rotate synchronously by the connecting rod 4, and the center spraying assembly and the lifting material carrying mechanism are driven to rotate synchronously by the connecting pipe 14; in the rotating process, the counterweights 25 slide outward along the sliding grooves 23 under the action of centrifugal force; the sliding of the counterweights 25 drives the platform 11 and the lifting material carrying mechanism to rise as a whole through the movable rods 28; the platform 11 rises from a position flush with the lower inner edge 8 to a position flush with the upper inner edge 7; in this process, the waste is thrown to the inner wall of the outer protective net 6 under the action of centrifugal force, and tends to be evenly distributed during the rising of the platform 11, thereby ensuring the uniformity of high-pressure spraying.

[0027] In example two, the structure and function of the equipment are further optimized on the basis of example one.

[0028] The diameter of the inner frame is 0.3-0.6 mm smaller than the diameters of the inner walls of the upper inner edge and the lower inner edge; this ensures that the inner frame 9 does not interfere with the upper inner edge 7 and the lower inner edge 8 during lifting, while also ensuring the effective sealing of the annular cleaning space to prevent waste from leaking out of the gap.

[0029] It also includes a driving mechanism for driving the rotating disc 3 to rotate; the driving mechanism includes a motor 32 fixedly installed on the inner wall of the equipment outer box 1, a gear 31 fixedly connected to the output end of the motor 32, and a gear ring 30 fixedly sleeved on the outside of the rotating disc 3 and engaged with the gear 31. The motor 32 transmits power to the rotating disc 3 through the engagement of the gear 31 and the gear ring 30, causing it to rotate.

[0030] It also includes a high-pressure water supply system for providing high-pressure cleaning liquid to the center spraying assembly; the high-pressure water supply system includes a water inlet pipe 16, a rotating sealing connector 15 fixedly connected to one end of the water inlet pipe 16 and sealingly and rotatably connected to the top of the connecting pipe 14; the other end of the water inlet pipe 16 extends outside the equipment outer box 1 and is connected to an external high-pressure water source; the rotating sealing connector 15 ensures that the high-pressure cleaning liquid can be stably and leak-free delivered to the flow divider 12 when the connecting pipe 14 rotates.

[0031] Optimization of the centrifugal lifting mechanism: In order to better control the movement of the counterweights 25 and the lifting of the platform 11, limit springs 24 are fixedly installed on the inner wall of the side of the sliding grooves 23 close to the center of the rotating disc, for limiting and buffering the inward sliding of the counterweights 25.

[0032] The counterweight 25 has a groove on the side away from the limiting spring 24, and a compression spring 26 is provided in the groove to provide a reset force for the counterweight 25. When the rotation speed of the turntable 3 decreases or stops, the elastic force of the compression spring 26 pushes the counterweight 25 toward the center of the turntable, thereby driving the platform 11 to descend.

[0033] Waste tumbling and redistribution mechanisms: A telescopic cylinder 18 is fixedly installed on the top inner wall of the outer casing 1 of the equipment. The output end of the telescopic cylinder 18 faces downward and corresponds to the rotary sealing connector 15. When the turntable 3 stops or rotates at low speed, under the action of the weight of the lifting material carrying mechanism, the reset force of the compression spring 26 and the auxiliary thrust provided by the telescopic cylinder 18, the platform 11 descends and resets to be flush with the lower inner edge 8.

[0034] Motor 32 can rotate in both directions, driving the rotating cleaning chamber to alternate between forward and reverse rotation. This allows the waste material to tumble and redistribute during the centrifugal force changes as the platform 11 resets and restarts. When the turntable 3 rotates forward, the waste material is thrown towards the outer protective net 6. When the turntable 3 rotates in reverse, the waste material moves in the opposite direction. During the process of the platform 11 descending and rising again, due to the changes in centrifugal force and the effect of gravity, the waste material is effectively tumbled, allowing all surfaces of the waste material to be fully exposed to the spray water flow and ultrasonic waves, greatly improving the uniformity and thoroughness of the cleaning.

[0035] After cleaning, the telescopic cylinder 18 extends, driving the platform 11 to descend below the lower inner edge 8, so that the waste material falls into the ultrasonic cleaner 2 below through the gap between the lower inner edge 8 and the platform 11, realizing the automatic discharge of waste material.

[0036] A limiting plate 17 is fixedly connected to the top inner wall of the outer casing 1 of the equipment to prevent the rotary sealing connector 15 from rotating with the connecting tube 14; this ensures the stability and sealing of the rotary sealing connector 15.

[0037] It also includes a feeding and guiding mechanism for accurately guiding the waste to be cleaned into the cleaning chamber. The feeding and guiding mechanism includes a first discharge pipe 19 fixedly installed inside the upper part of the outer casing 1 and extending to its exterior, two sets of baffle rings 20 fixedly connected to the top of the turntable 3, a guide ramp 21 disposed between the two sets of baffle rings 20, and a second discharge pipe 22 disposed below the turntable 3 with its top opening located between the two sets of baffle rings 20. The bottom outlet of the second discharge pipe 22 is located above the platform 11. The waste enters through the first discharge pipe 19, is guided by the baffle rings 20 and the guide ramp 21, and finally falls accurately onto the platform 11 through the second discharge pipe 22.

[0038] Example 3, based on Example 2, further describes the moving mechanism of the ultrasonic cleaner 2.

[0039] Dual-axis moving mechanism 33: The ultrasonic cleaner 2 is connected to the inner wall of the outer casing 1 of the equipment through the dual-axis moving mechanism 33; the dual-axis moving mechanism 33 includes a guide rail, a slider, a drive motor and a lead screw.

[0040] The dual-axis moving mechanism 33 has two main functions: Waste collection: The dual-axis moving mechanism 33 drives the ultrasonic cleaner 2 to move upward, enabling it to collect the waste falling from the rotating cleaning chamber.

[0041] Material Removal: After cleaning, the dual-axis moving mechanism 33 drives the ultrasonic cleaner 2 to move out from the front of the outer casing 1, allowing staff to easily remove the cleaned waste. This further improves the automation level and ease of operation of the equipment.

[0042] Overall workflow overview: Feeding: The NdFeB waste to be cleaned enters through the first feeding pipe 19, is guided by the baffle ring 20 and the guide plate 21, and falls onto the platform 11 through the second feeding pipe 22.

[0043] High-pressure spraying and waste leveling: Motor 32 drives turntable 3 to rotate forward, which drives the rotating cleaning chamber to rotate through gear 31 and gear ring 30; under the action of centrifugal force, counterweight 25 slides outward, driving platform 11 to rise, so that the waste is thrown to the inner wall of outer protective net 6 and tends to be distributed flat; high-pressure water supply system provides high-pressure cleaning fluid to the central spraying assembly through water inlet pipe 16, rotating sealing connector 15 and connecting pipe 14, and spray pipe 13 performs high-pressure spraying cleaning on the waste.

[0044] Waste tumbling and redistribution: During the cleaning process, motor 32 alternates between forward and reverse rotation, driving the rotating cleaning chamber to alternate between forward and reverse rotation; when the speed decreases, the counterweight 25 is reset under the action of compression spring 26 and limit spring 24, and platform 11 descends; when it rotates again, platform 11 rises again; so that the waste is fully tumbling and redistributed under the action of centrifugal force and gravity, ensuring the uniformity and thoroughness of cleaning.

[0045] Ultrasonic cleaning: After high-pressure spray cleaning, the telescopic cylinder 18 extends, and the drive platform 11 descends below the lower inner edge 8, causing the waste material to automatically fall into the ultrasonic cleaner 2 below. The dual-axis moving mechanism 33 drives the ultrasonic cleaner 2 to receive the waste material and perform ultrasonic cleaning.

[0046] Discharge: After ultrasonic cleaning is completed, the dual-axis moving mechanism 33 drives the ultrasonic cleaner 2 to move out from the front of the outer casing 1 of the equipment, making it easy to remove the cleaned waste material.

[0047] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
