Description

Technical Field

[0001] The invention belongs to the technical field of electrolytic refining of precious metal silver, and in particular relates to a cleaning device for a conductive rod of an anode plate hung in silver electrolysis. Background Art

[0002] In the traditional silver electrolytic refining production process, the electrolytic anode is composed of a conductive rod and a gold-silver alloy plate, and the titanium plate is the electrolytic cathode. The conductive rod needs to be used repeatedly during the electrolysis process. In the actual electrolytic production process, one end of the conductive rod needs to be placed on the conductive motherboard on the electrolytic cell to obtain electricity. Under high current density, the conductive rod is very easy to heat up and oxidize and turn black. In the high-temperature and strongly acidic corrosive environment above the electrolyte surface, other impurities are also easily attached to the surface of the conductive rod, causing the conductive performance of the conductive rod to continue to decline during the electrolysis process, resulting in a series of problems such as increased electrolytic cell voltage, increased power consumption, and reduced quality of electrolytic silver powder. Various crystalline stains and dirt are attached to the conductive rod, and it needs to be cleaned to ensure its conductive effect. The existing method of cleaning the conductive rod is manual grinding and cleaning, which is inefficient, has poor cleaning effect, high labor cost, and cannot meet the needs of modern production. There is also a mechanical cleaning method, but the current wire brush cleaning of the conductive rod will cause surface damage to the conductive rod, affecting its reusability.

[0003] Therefore, how to provide a cleaning device for the conductive rods of silver electrolysis anode plates is a problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0004] In view of this, the present invention provides a cleaning device for silver electrolysis anode plate conductive rods, which can remove dirt on the rod surface by mechanical brushing, has good cleaning effect, high efficiency and saves labor costs.

[0005] In order to achieve the above object, the present invention adopts the following technical solution: a cleaning device for anode plate conductive rods in silver electrolysis, comprising:

[0006] A box body, wherein a feed port is provided at one end of the top of the box body, and a discharge port is provided on the side wall at the other end of the box body;

[0007] A conveyor line is arranged inside the box body, with one end of the conveyor line located below the feed port and the other end close to the discharge port, and the bars are sequentially conveyed on the conveyor line;

[0008] A spray brushing assembly is arranged inside the box and cleans the bars on the conveyor line;

[0009] A vibration mechanism is installed inside the box body and near one end of the discharge port. A vibration bracket is provided on the vibration mechanism. The vibration bracket lifts and vibrates the bar materials on the conveyor line. Driven by the conveyor line, the bar materials pass through the spray brush assembly and the vibration bracket in sequence and are discharged through the discharge port.

[0010] The controller is fixed on the outer side wall of the box and is connected with the conveying line, the spraying and brushing assembly, and the vibration mechanism by electrical signals.

[0011] The beneficial effects of the present invention are: the conveyor line is used to circulate and reciprocate to convey the rod material forward, and the rod material passes through the spray and brushing assembly and the vibration mechanism in the process of moving to the discharge port. The spray and brushing assembly can spray cleaning liquid and complete the smearing and brushing of the rod material to remove the stains hard on the surface of the rod material. After this cleaning process, the remaining dirt will be vibrated clean by the vibration mechanism. The present invention can not only comprehensively wet and clean the surface of the rod material, but also remove the attached hard stains by mechanical brushing, freeing both hands and performing a thorough and automatic cleaning of the rod material with high work efficiency.

[0012] Preferably, a lifting buffer mechanism is provided inside the box and below the feed port, and the lifting buffer mechanism is electrically connected to the controller. The lifting ends of the lifting buffer mechanism are located on both sides of the conveyor line and move up and down to transfer the rod material at the feed port to the conveyor line.

[0013] The resulting technical effect is: there is a certain height difference between the feeding port of the box and the conveyor line, and the lifting buffer mechanism is used to transition the bar material, and the bar material is steadily delivered to the conveyor line to avoid damage to the bar material due to the height difference.

[0014] Preferably, the axial length dimension of the bar is greater than the width dimension of the conveying line.

[0015] The resulting technical effect is that longer bars can be placed on the conveyor line and pushed forward by the conveying mechanism on the conveyor line. Of course, under the constraints on both sides of the box, the bars will not deviate significantly.

[0016] Preferably, the spray brushing assembly includes a high-pressure nozzle and a brush roller. The high-pressure nozzle is fixed on the inner top of the box and faces the rods on the conveyor line. The high-pressure nozzle sprays high-pressure cleaning fluid; the brush roller is rotatably connected to the inside of the box and is located above the conveyor line. The brush roller performs a smear-type brushing on the rods soaked with the cleaning fluid.

[0017] The resulting technical effect is: the high-pressure nozzle can spray high-pressure cleaning fluid to preliminarily remove dirt on the surface of the rod and wet the rod. The subsequent high-speed rotation of the brush roller can clean the dirt on the surface of the rod again to achieve further cleaning.

[0018] Preferably, the vibration mechanism includes a vibration source, a vibration bracket and a lifter, the lifter is vertically fixed to the inner bottom of the box, a buffer pad is provided at the connection between the lifter and the box, the vibration bracket is fixed to the lifting end of the lifter, the vibration bracket is an arc-shaped fork bracket, there are two groups of vibration brackets and they are located on both sides of the conveyor line, the vibration bracket supports the rod material under the drive of the lifting end of the lifter, the vibration source is fixed on the lifter and is electrically connected to the controller signal.

[0019] The resulting technical effect is: the vibration mechanism vibrates by relying on the vibration source, and the rods enter the supporting range of the vibration bracket under the push of the conveyor line after the brushing is completed, and the rods are lifted upward by the drive of the lifter. The vibration of the rods is achieved by relying on the vibration source. After the vibration cleaning is completed, the rods are lowered to the conveyor line for continued transportation. In this process, the rods are vibrated to remove stubborn dirt, achieve deep cleaning, and shake off the cleaning liquid on the rods.

[0020] Preferably, the vibration source is an electromagnetic vibrator.

[0021] Preferably, a servo motor for controlling the rotation of the brush roller is installed on the box body, and the servo motor is connected to the controller via electrical signals.

[0022] The resulting technical effect is: the servo motor is the driving source for the rotation of the brush roller, the outer layer of the brush roller is soft and will not damage the rod material.

[0023] Preferably, a high-pressure water pump is fixed on the box body, the high-pressure water pump is electrically connected to the controller, and a high-pressure pipe is connected between the high-pressure water pump and the high-pressure nozzle.

[0024] The resulting technical effect is: the high-pressure water pump provides cleaning fluid at a certain pressure, which has a better flushing effect.

[0025] Preferably, the controller is a PLC logic controller.

[0026] The resulting technical effect is that the operation of the conveying line, spray brushing components and vibration mechanism can be automatically controlled according to the preset program, so as to realize the overall coordination and automation of the conductive rod cleaning operation without human intervention.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See the attached Figures 1 to 5 According to an embodiment of the present invention, a cleaning device for anode plate conductive rods of silver electrolysis is provided, which comprises:

[0035] Box 1 is made of stainless steel sheet material and has a closed cubic structure. The internal space is used to install various devices. A feed port 2 is provided at one end of the top of the box. The feed port is designed as a trumpet mouth, which is larger at the top and smaller at the bottom. The width of the lower port is slightly wider than the length of the conductive rod. A discharge port 3 is provided on the side wall of the other end of the box 1.

[0036] Conveyor line 4 is arranged inside the box 1, with one end of the conveyor line located below the feed port 2 and the other end close to the discharge port 3. Bars 5 are sequentially conveyed on the conveyor line 4; a bar collection facility is provided outside the box;

[0037] The spray brushing assembly 6 is arranged inside the box 1 and cleans the bars on the conveyor line 4;

[0038] The vibration mechanism 7 is installed inside the box body 1 and near one end of the discharge port 3. The vibration mechanism 7 is provided with a vibration bracket 702. The vibration bracket 702 is used to lift and vibrate the bar material on the conveyor line 4, applying low-frequency vibration to the brushed bar material. After the vibration is completed, the vibration bracket lowers the bar material. Driven by the conveyor line, the bar material 5 passes through the spray brush assembly 6 and the vibration bracket 702 in sequence and is discharged through the discharge port.

[0039] The controller 8 is fixed on the outer wall of the box body 1 and is electrically connected to the conveying line 4, the spraying and brushing assembly 6, and the vibration mechanism 7.

[0040] In other embodiments, a lifting buffer mechanism 9 is provided inside the box body 1 and below the feed port 2. The lifting buffer mechanism 9 is electrically connected to the controller 8. The lifting ends of the lifting buffer mechanism 9 are located on both sides of the conveyor line 4 and move up and down to transfer the rods at the feed port to the conveyor line. In order to better catch the rods, the lifting end of the lifting buffer mechanism is a fork type.

[0041] In other specific embodiments, the axial length of the bar 5 is greater than the width of the conveying line 4 .

[0042] In some other embodiments, the spray brushing assembly 6 includes a high-pressure nozzle 601 and a brush roller 602. The high-pressure nozzle 601 is fixed on the inner top of the box body 1 and faces the rod material on the conveyor line. The high-pressure nozzle 601 sprays high-pressure cleaning liquid; the brush roller 602 is rotatably connected to the inside of the box body 1 and is located above the conveyor line 4. The brush roller 602 performs a smearing brushing on the rod material soaked with the cleaning liquid to remove pollutants such as silver nitrate attached to the surface of the conductive rod.

[0043] In some other specific embodiments, the vibration mechanism 7 includes a vibration source 701, a vibration bracket 702, and a lifter 703. The lifter 703 is vertically fixed to the inner bottom of the box body 1. A cushion is provided at the connection between the lifter 703 and the box body 1. The vibration bracket 702 is fixed to the lifting end of the lifter 703. The vibration bracket 702 is an arc-shaped fork frame. There are two sets of vibration brackets 702, which are located on both sides of the conveyor line. The vibration bracket 702 is driven by the lifting end of the lifter 703 to support the bar material. The vibration source 701 is fixed to the lifter 703 and is electrically connected to the controller 8. The vibration mechanism can shake off tiny attachments on the bar material and remove residual cleaning liquid on the surface of the conductive rod.

[0044] In other embodiments, the vibration source 701 is an electromagnetic vibrator with a frequency of 50 Hz.

[0045] In some other embodiments, a servo motor 603 for controlling the rotation of the brush roller 602 is installed on the box body 1, and the servo motor 603 is electrically connected to the controller 8.

[0046] In some other specific embodiments, a high-pressure water pump 604 is fixed to the housing 1 and electrically connected to the controller 8. A high-pressure pipe is connected between the high-pressure water pump 604 and the high-pressure nozzle 601. The high-pressure nozzle is a rotating nozzle that sprays 360 degrees and can form a strong cleaning liquid jet at a pressure of 60-80 bar. The high-pressure nozzle sprays the cleaning liquid containing an acidic solution onto the conductive rod to provide a strong jet flushing to dissolve oxides attached to the surface of the conductive rod.

[0047] In other embodiments, controller 8 is a PLC logic controller. The PLC system is installed in a control cabinet on the side of the box and includes a CPU module, I / O module, Ethernet communication module, etc. The control logic program is written in the PLC to define the on / off and operating parameters of the conveyor line, high-pressure water pump, servo motor, vibration mechanism, etc.

[0048] The PLC system connects to actuators such as motors, pneumatic cylinders, and vibrators via digital I / O points, and to sensors via analog I / O points. The HMI interface is connected to the PLC and is used to monitor system operation and modify control parameters. In automatic mode, the PLC activates each device according to the control logic sequence to implement the cleaning process and monitors the operating status of sensor feedback. The PLC can control the conveyor device to sequentially move conductive rods in and out of the box, control the spray pressure and duration of the spray device, and control the speed and number of brushing cycles of the brush roller. After cleaning a group of conductive rods, the PLC automatically resets the system to prepare for the next batch of cleaning operations. If a fault alarm occurs, the PLC can execute an emergency stop function to ensure system safety. The cleaning fluid can be collected and reused in a storage tank at the bottom of the box.

[0049] The conveyor line can use screw conveyors, hydraulic push rods, etc. to realize the automatic conveyance of conductive rods. The screw conveyor uses the rotating screw to push the conductive rods to achieve conveyance; the hydraulic push rod uses the hydraulic cylinder moving back and forth to push the conductive rods in and out of the box.

[0050] This device uses a variety of cleaning processes to thoroughly clean the surface of the conductive rod; the control system is integrated into the box, and can automatically control the operation of the conveyor line and spray brush components according to the preset program, realizing the overall coordination and automation of the conductive rod cleaning operation without human intervention.

[0051] As for the devices and methods of use disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the description of the methods.
