Description

Technical Field

[0001] This invention relates to the field of copper removal electrolysis technology, specifically to a black copper sludge cleaning machine. Background Technology

[0002] In copper electrolysis production, the electrolyte purification process typically employs copper stripping electrolysis to adsorb harmful impurities in the electrolyte. This involves using the residue from the crude copper anode plate as a cathode to adsorb impurities such as arsenic, antimony, and bismuth from the electrolyte, thus purifying it. During the copper electrolysis purification process, after the secondary copper stripping electrolysis, black copper slurry and copper stripping supernatant are produced. The black copper slurry adheres to the cathode and needs to be periodically removed.

[0003] When scraping off black copper sludge, the scraping force required varies because the thickness of the black copper sludge on each cathode plate is different. Existing black copper sludge cleaning machines use many sensors to detect the thickness of the black copper sludge and thus control the scraping force. These machines are not only very complex and prone to failure, but also expensive. Summary of the Invention

[0004] The purpose of this invention is to provide a novel black copper sludge cleaning machine that can adaptively scrape off black copper sludge according to its thickness. It has a simple structure, strong practicality, and low cost.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A black copper sludge cleaning machine is used to remove black copper sludge from plate-shaped products. The black copper sludge cleaning machine includes a frame, a lifting frame, a scraper assembly, a longitudinal drive device, and a lifting drive device. The frame is a cuboid frame, including columns on all four sides and a rectangular frame on the upper surface. Multiple upper fixed plates are arranged horizontally at intervals within the rectangular frame, and the interval between the multiple upper fixed plates matches the thickness of the plate-shaped product.

[0007] The lifting frame is disposed inside the cuboid frame, including a rectangular lifting frame planar frame;

[0008] The scraper assembly includes a front scraper, a rear scraper, a front scraper longitudinal moving plate, a rear scraper longitudinal moving plate, a front scraper tension spring, and a rear scraper tension spring. The front and rear scrapers are laterally spaced within the lifting frame plane, and the spacing between the front and rear scrapers of the same plate-shaped product matches the thickness of the plate-shaped product. The front scraper longitudinal moving plate is longitudinally positioned on the side of the front scraper, and the rear scraper longitudinal moving plate is longitudinally positioned on the side of the rear scraper. One end of the front scraper tension spring is connected to the upper side of the front scraper, and the other end is connected to the front scraper longitudinal moving plate. One end of the rear scraper tension spring is connected to the upper side of the rear scraper, and the other end is connected to the rear scraper longitudinal moving plate. The front and rear scraper tension springs are arranged in a staggered manner.

[0009] The longitudinal drive device is mounted on the lifting frame and drives the front scraper longitudinal moving plate to move backward and the rear scraper longitudinal moving plate to move forward.

[0010] The lifting drive device drives the lifting frame to move up and down.

[0011] The black copper sludge cleaning machine using the above technical solution first fixes the upper end of the plate-shaped product with black copper sludge between the gaps of the upper fixed plate. The lower section of the plate-shaped product is placed inside the rectangular frame, and then placed on the lifting frame plane frame to contact the scraper assembly. Since one end of the front scraper tension spring is connected to the upper side of the front scraper and the other end is connected to the longitudinal moving plate of the front scraper, and one end of the rear scraper tension spring is connected to the upper side of the rear scraper and the other end is connected to the longitudinal moving plate of the rear scraper, the front scraper... The front scraper spring and the rear scraper spring are arranged in a staggered pattern. When the longitudinal drive device drives the front scraper longitudinal moving plate to move backward and the rear scraper longitudinal moving plate to move forward, under the spring tension of the front and rear scraper springs, the front scraper adaptively and tightly contacts the front of the plate-shaped product, and the rear scraper adaptively and tightly contacts the back of the plate-shaped product. Then, driven by the lifting drive device, the lifting frame moves upward. During the movement, the front and rear scrapers remove the black copper sludge from the surface of the plate-shaped product. Due to this structure of the front and rear scraper springs, the front scraper acts backward tightly on the front surface of the plate-shaped product, and the rear scraper acts forward tightly on the rear surface of the plate-shaped product. In this way, regardless of whether the thickness of the black copper sludge on each plate-shaped product (including but not limited to the cathode plate) is uniform, it can adaptively act on the surface of the plate-shaped product. There is no need to install sensors to detect the thickness of the black copper sludge. The structure is simple, practical, and of stable quality, with low cost.

[0012] Furthermore, the lifting frame planar frame is defined to include multiple transversely arranged transverse partitions, two longitudinal plates, and a mounting base. The longitudinal plates are installed on the left and right sides of the transverse partitions, and the mounting base is located at the front end of the transverse partitions.

[0013] Furthermore, the specific fixing method of the front and rear scrapers is defined as follows: the number of front and rear scrapers is N, the number of upper fixing plates is N plus 1, and the front and rear scrapers are alternately arranged above the multiple transverse partitions. The front and rear scrapers are respectively hinged to the corresponding transverse partitions. The two flaps of the hinge on the front scraper are respectively located at the front end of the front scraper and the front end of the corresponding transverse partition, and the two flaps of the hinge on the rear scraper are respectively located at the rear end of the rear scraper and the rear end of the corresponding transverse partition. The hinged connection method can better and more firmly fix the position of the front and rear scrapers, and ensure their rotation. Furthermore, it ensures that under the spring force of the front and rear scraper springs, the front and rear scrapers always adhere to the front and rear surfaces of the plate-shaped product, thereby better removing the black copper sludge from the plate-shaped product.

[0014] Furthermore, the longitudinal drive device is further defined as including a longitudinal servo motor and a transmission fork. The longitudinal drive device is mounted on the mounting base. The output shaft of the motor is laterally disposed on the outside of the mounting base. The transmission fork is connected to the output shaft of the motor. The transmission fork is provided with a forward fork and a backward fork. A front fork connecting plate is provided at the front end of the longitudinal moving plate of the rear scraper. The forward insertion rod is hinged to the front fork connecting plate. A rear fork connecting plate is provided at the front end of the longitudinal moving plate of the front scraper. The backward insertion rod is hinged to the rear fork connecting plate. This transmission fork hinge design, with its connecting plates for the front and rear forks, connects to the longitudinal moving plates of the front and rear scrapers. A single transverse motor can synchronously control the opposing relative movements of the longitudinal moving plates. When the motor rotates, the transmission fork rotates, simultaneously rotating the forward fork and driving the rear scraper longitudinal moving plate forward. The rear scraper tension spring moves forward, and the rear scraper experiences forward force on the back of the plate-shaped product. Similarly, synchronously, when the motor rotates, the transmission fork rotates, simultaneously rotating the backward fork and driving the front scraper longitudinal moving plate backward. The front scraper tension spring moves backward, and the front scraper experiences forward force on the front of the plate-shaped product. This ensures synchronous control with a single motor, saving costs and simplifying operation. It also better guarantees the synchronized operation of the front and rear scrapers, resulting in more effective removal of black copper sludge from the plate-shaped product.

[0015] Furthermore, the lifting drive device is defined as a worm gear jack, which is located inside the column. The upper output shaft of the worm gear jack is a lead screw, and a nut is provided on the lead screw. The nut abuts against the four corners of the rectangular lifting frame plane frame, and the upper end of the lead screw is connected to the lead screw bearing seat. This lifting servo motor device can slowly move the entire lifting frame up and down, cleaning the black copper sludge on the plate-shaped product during the movement. It can reciprocate up and down multiple times to ensure the cleaning effect.

[0016] Furthermore, the scraper assembly includes a scraper seat and a scraper body fixedly connected to the scraper seat. This separate arrangement of the scraper body and scraper seat allows for easier replacement of the scraper body and facilitates maintenance.

[0017] In addition, the black copper sludge cleaning machine also includes a hopper, which is located below the machine frame. The purpose of the hopper is to better collect and process the black copper sludge and reduce pollution.

[0018] Furthermore, the black copper mud cleaning machine also includes a safety door, which is located on the four sides of the frame. The safety door is equipped with a handle. The safety door can better ensure safety during operation and the cleanliness of the surrounding environment, and can also reduce some noise. The handle makes it easy to open and close the safety door. The safety door can be connected by a sliding track or by an outward-opening hinge.

[0019] Furthermore, the black copper sludge cleaning machine also includes a control box, which is located at the rear end of the frame. This makes the overall structure more reasonable, with the motor and transmission fork at the front and the control box at the rear.

[0020] The beneficial effects of this invention are: by using a mechanical device to scrape the black copper sludge, replacing manual labor for cleaning the black copper sludge, not only is work efficiency improved, but also physical harm to workers is avoided. Attached Figure Description

[0037] The longitudinal drive device 4 is mounted on the lifting frame 2, driving the front scraper longitudinal moving plate 33 to move backward and the rear scraper longitudinal moving plate 34 to move forward; the lifting drive device 5 drives the lifting frame 2 to move up and down.

[0038] The lifting frame planar frame 21 includes multiple horizontally arranged transverse partitions 211, two longitudinal plates 212, and a mounting base 213. The longitudinal plates 212 are installed on the left and right sides of the transverse partitions 211, and the mounting base 213 is located at the front end of the transverse partitions 211.

[0039] The number of front scrapers 31 and rear scrapers 32 is N, and the number of upper fixing plates 121 is N plus 1. The front scrapers 31 and rear scrapers 32 are alternately arranged above the multiple transverse partitions 211. The front scrapers 31 and rear scrapers 32 are respectively hinged to the corresponding transverse partitions 211. The two flaps of the hinge 6 on the front scraper 31 are respectively arranged at the front end of the front scraper 31 and the front end of the corresponding transverse partition 211. The two flaps of the hinge 6 on the rear scraper 32 are respectively arranged at the rear end of the rear scraper 32 and the rear end of the corresponding transverse partition 211.

[0040] The longitudinal drive device 4 is mounted on the mounting base 213. The longitudinal drive device 4 includes a longitudinal servo motor 41 and a transmission fork 42. The output shaft of the motor is laterally arranged on the outside of the mounting base 213. The transmission fork 42 is connected to the output shaft of the longitudinal servo motor 41.

The forward insertion rod 421 is hinged to the rear fork connecting plate 341. The front end of the front scraper longitudinal moving plate 33 is provided with a front fork connecting plate 331. The backward insertion rod 422 is hinged to the front fork connecting plate 331.

[0041] The lifting drive device 5 is a worm gear jack, which is located inside the column 11. The upper output shaft of the worm gear jack is a lead screw 51, which is equipped with a nut. The nut abuts against the four corners of the rectangular lifting frame plane 21. The upper end of the lead screw 51 is connected to the lead screw bearing seat 52.

[0042] The front scraper 31 includes a front scraper seat and a front scraper body fixedly connected to the front scraper seat; the rear scraper 32 includes a rear scraper seat and a rear scraper body fixedly connected to the rear scraper seat.

[0044] In use, firstly, the upper end of the plate-shaped product 10 with black copper mud is fixed between the gaps of the upper fixing plate 121. The lower section of the plate-shaped product 10 is placed inside the rectangular frame 1, and the lower section of the plate-shaped product 10 is placed on the lifting frame plane frame 121 and in contact with the scraper assembly 3. Since one end of the front scraper tension spring 35 is connected to the upper side of the front scraper 31 and the other end is connected to the front scraper longitudinal moving plate 33, and one end of the rear scraper tension spring 36 is connected to the upper side of the rear scraper 32 and the other end is connected to the rear scraper longitudinal moving plate 34, the front scraper tension spring 35 and the rear scraper tension spring 36 are arranged in a staggered manner. Under the rotation drive of the longitudinal servo motor 41, the longitudinal servo motor 41 drives... The backward fork 422 then drives the front scraper longitudinal moving plate 33 to move backward, and the front scraper tension spring 35 is stretched backward. At the same time, the longitudinal servo motor 41 drives the forward fork 421 to drive the rear scraper longitudinal moving plate 34 to move forward, and the rear scraper tension spring 36 is stretched forward. Under the spring tension of the front scraper tension spring 35 and the rear scraper tension spring 36, the front scraper 31 adaptively and closely contacts the front of the plate-shaped product 10, and the rear scraper 32 adaptively and closely contacts the back of the plate-shaped product 10. Then, driven by the lifting drive device 5, the lifting frame 2 moves upward. During the movement, the front scraper 31 and the rear scraper 32 will remove the black copper sludge from the surface of the plate-shaped product 10.

[0045] In the above specific embodiment, the longitudinal drive device 4 includes a longitudinal servo motor 41 and a transmission fork 42. The output shaft of the motor is laterally arranged on the outer front end of the lifting frame plane frame 21. The transmission fork 42 is connected to the output shaft of the longitudinal servo motor 41. The transmission fork 42 is provided with a forward fork 421 and a backward fork 422. The front end of the rear scraper longitudinal moving plate 34 is provided with a rear fork connecting plate 341. The forward fork 421 is hinged to the rear fork connecting plate 341. The front end of the front scraper longitudinal moving plate 33 is provided with a front fork connecting plate 331. The backward fork 422 is hinged to the front fork connecting plate 331. The transmission fork 42 is shaped like a two-pronged fork, with one fork 421 and the other fork 422. Both the forward fork 421 and the backward fork 422 are connected to the fork handle. The backward fork 422 is hinged to the front fork connecting plate 331.

[0046] Of course, other connection methods can also be used, such as Figure 2The above-described technical solution also includes a movable positioning shaft 423. The longitudinal driving device includes a longitudinal servo motor and a transmission fork. The output shaft of the motor is laterally disposed on the outer front end of the lifting frame plane frame. The transmission fork is connected to the output shaft of the motor and has a forward fork and a backward fork. The front end of the rear scraper longitudinal moving plate is provided with a rear fork connecting plate. The rear end of the rear fork connecting plate is provided with an outer upper and lower strip hole 3411, and the front end of the rear fork connecting plate is provided with an outer left and right strip hole 3412. The front scraper longitudinal... A fork connecting plate is provided at the front end of the moving plate. The rear end of the fork connecting plate is provided with an inner upper and lower strip hole 3311, and the front end of the fork connecting plate is provided with an inner left and right strip hole 3312. The forward fork 421 moves in conjunction with the outer upper and lower strip hole 3411, the backward fork 422 moves in conjunction with the inner upper and lower strip hole 3411, one end of the moving positioning shaft 423 moves in conjunction with the outer left and right strip hole 3412, and the other end of the moving positioning shaft 423 moves in conjunction with the inner left and right strip hole 3312.

[0047] In this manner, when the transmission fork 42 rotates, the forward fork 421 moves within the outer upper and lower strip holes 3411, driving the rear scraper longitudinal moving plate 34 to move, and the backward fork 422 moves within the inner upper and lower strip holes 3311, driving the front scraper longitudinal moving plate 33 to move. Considering the maximum limit distance of movement, a moving positioning shaft 423 is provided in the outer left and right strip holes 3412 and the inner left and right strip holes 3312. However, when at the maximum limit distance, the leftmost side of the outer left and right strip holes 3412 and the left and right sides of the inner left and right strip holes 3412 contact the moving positioning shaft 423 and are limited, preventing further movement.

[0048] Because of this structure of front and rear scraper springs, the front scraper acts backward on the front surface of the plate-shaped product, and the rear scraper acts forward on the rear surface of the plate-shaped product. In this way, regardless of whether the thickness of the black copper sludge on each plate-shaped product (including but not limited to the cathode plate) is uniform, it can adaptively act on the surface of the plate-shaped product. There is no need to install sensors to detect the thickness of the black copper sludge. The structure is simple, practical, and has stable quality and low cost.

[0049] It should be noted that words indicating direction in this article, such as "up" and "down," are all in the format of "upper" and "lower." Figure 1 The direction setting is for ease of description only and has no other specific meaning.

[0050] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
