Description

Technical Field

[0002] The conductive contacts of the electrolytic cathode plate need to be reused, and the contact surface needs to be cleaned, otherwise the conductive performance will be affected. For example, in the production scale of wet zinc smelting above 100kt / a, most of the 2.6㎡ and 3.2㎡ rolled aluminum plates are used as cathode plates of the zinc electrowinning system. The copper conductive contacts of the cathode plate are easily oxidized in an acidic environment, and the copper oxide or copper sulfate compounds generated on the contact surface will affect the conductive performance of the plate, causing heating of the cathode plate and uneven precipitation of zinc sheets. Due to the large number of cathode plates in the zinc electrowinning system above 100kt / a, manual cleaning is more difficult. At present, there is no cathode plate conductive contact cleaning device designed for the cathode plate washing machine. Although some people have designed some cleaning devices, such as electrolytic cathode plate conductive contact grinders, such devices use rigid contact cleaning, which causes greater damage to the conductive contacts, unsatisfactory cleaning effects, and low operating efficiency.

DETAILED DESCRIPTION

[0018] In this embodiment, refer to Figure 1-3The electrolytic cathode plate conductive contact brushing device includes a control system, a cleaning mechanism, a driving mechanism and a moving mechanism. The control system is controlled by PLC. The driving mechanism includes a motor 3, and the motor 3 is connected to the cleaning mechanism through a transmission mechanism; the cleaning mechanism includes a first roller brush 11 and a second roller brush 12. The first roller brush 11 is connected to the motor 3 through a driving shaft 21, and a driving wheel 23 is installed on the driving shaft 21; the second roller brush 12 is connected to a driven shaft 22, and a driven wheel 24 is installed on the driven shaft 22. The driven wheel 24 is connected to the driving wheel 23 to form a synchronously rotatable structure; the moving mechanism includes a transverse movement mechanism and a lifting mechanism. The transverse movement mechanism is installed on the lifting mechanism, and the motor 5, the driving shaft 21 and the driven shaft 22 are installed on the transverse movement mechanism, so that the first roller brush 11 and the second roller brush 12 can perform lifting and transverse movement to ensure that the conductive contacts are fully cleaned.

[0019] The lifting mechanism includes a lifting plate 6 and a lifting cylinder 8 . The lifting plate 6 is horizontally mounted on the lifting cylinder 8 , and the lifting cylinder 8 is upright mounted on a base 7 .

[0020] The transverse movement mechanism includes a movable plate 41 and a transverse push cylinder 42. The movable plate 41 is horizontally movable and mounted on the lifting plate 6. The transverse push cylinder 42 is fixedly mounted on the lifting plate 6. The movable plate 41 is connected to the transverse push cylinder 42. The transverse push cylinder 42 pushes the movable plate 41 to perform transverse movement. The moving direction is perpendicular to the extension direction of the driving shaft 21. When the roller brush contacts the conductive contact, the transverse push cylinder 42 pushes the movable plate 41. The pushing stroke is equal to the width of the conductive contact, so as to fully clean the conductive contact.

[0021] The movable plate 41 is movably mounted on the lifting plate 6 through three sets of linear bearings 44 at the front, middle and rear, in cooperation with the sliding rod 43 .

[0022] The lifting cylinder 8 includes two three-axis cylinders, and the lifting cylinder 8 has two upper and lower magnetic switches. The upper magnetic switch constitutes an upper limit switch 91, and the lower magnetic switch constitutes a lower limit switch 92, so as to monitor the device's descending and rising signals, and provide switching quantities for the PLC to ensure stable and reliable operation of the device.

[0023] A bearing seat 5 is mounted on the movable plate 41 via a bracket 51 , and the driving shaft 21 and the driven shaft 22 are respectively mounted via corresponding bearing seats 5 into a parallel horizontal structure so that the first roller brush 11 and the second roller brush 12 are flush with each other.

[0024] The driving shaft 21 is connected to the motor 3 via a coupling 31 .

[0025] The driving wheel 21 and the driven wheel 22 use synchronous pulleys with the same structure and are connected by a synchronous belt to achieve the same rotation speed and driving time for the two sets of roller brushes. The center distance between the two sets of roller brushes is the same as the pitch of the cathode plates on the cathode conveyor line.

[0026] This device is installed on both sides of the double-plate lifting and scrubbing machine for supporting use, and cleans the conductive contacts of the cathode plates of the electrolytic cells on both sides respectively. The conductive contacts are cleaned by steam blowing and nylon roller brushing.

[0027] When the automatic mode of the double-plate scrubber is turned on, the motor 3 starts to work and the roller brush starts to rotate. When the cathode conveyor line of the scrubber conveys two cathode plates and stops, the lifting hanger lifts the cathode plates, and the two sets of lifting cylinders 8 are lifted, and the roller brush is lifted to contact the cathode plate conductive head. Steam starts to spray, and the horizontal push cylinder 42 pushes the roller brush platform (i.e., the movable plate 41) to make a cycle of reciprocating motion to achieve complete cleaning of the contact surface of the conductive contact, and the roller brush cleans the conductive contacts of the two cathode plates at one time.

[0028] The contact surface and contact corners of the conductive contact are firstly washed by steam for 3 seconds, and then washed by roller brush for 10 seconds. When the washing machine hanger descends to the center position, the lifting cylinder 8 descends to the initial position, the roller brush and the conductive contact are no longer in contact, and the cathode conveyor line of the washing machine continues to convey the cathode plate.

[0029] According to the working rules of the cathode plate surface of the scrubber, the conductive contact brushing device performs a cyclic cleaning action, and the devices on both sides realize automatic switching according to the rules of zinc flakes being deposited out of the slot.

[0030] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
