Description

Technical Field

[0001] This utility model relates to the field of slag metal recovery technology, specifically to a metal recovery device for anode slag. Background Technology

[0002] Anode slag is a byproduct of copper electrolysis. Its main components are copper oxide and iron oxide, as well as small amounts of sulfur, nickel, lead, zinc and other elements. Recycling anode slag not only helps reduce resource waste, but also protects the environment.

[0003] In practice, anode slag is relatively brittle and hard, and sometimes slag and metal objects stick together, making them difficult to separate. In addition, existing technologies often use rinsing to further wash away the metal objects in the slag, but lack reliable water supply and drainage structures. Therefore, we propose a metal recovery device for anode slag. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a metal recovery device for anode slag. This device features a reliable metal recovery unit. The anode slag to be processed is poured into an inner rotating drum. As the drum rotates, the slag is thrown towards the corrugated wall. The raised strips on the corrugated wall cause the slag to tumble continuously, causing the slag adhering to the metal to detach and separate. Water sprayed from the top washes the metal. When solenoid valve one closes the drain pipe, the sprayed water accumulates inside the inner rotating drum, completely immersing the slag containing metal in the water, thus improving the cleanliness of the cleaning. Furthermore, with the help of water buoyancy, the washed metal, under magnetic attraction, can better drift towards the electromagnet. When solenoid valve one opens, the cleaning wastewater flows along the drain pipe into the sewage chamber for temporary storage. Solenoid valve two opens the drain outlet to discharge the sewage, effectively solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal recovery device for anode slag, comprising a base, a metal recovery unit, and a wastewater discharge unit;

[0006] Base: It is a flat cylindrical structure, and an upper cylinder is fixedly connected to the upper side. The connection between the inner walls of the two is provided with a stepped structure.

[0007] Metal recycling unit: includes an inner rotating cylinder, corrugated wall, electromagnet, collection basin, filter screen, and handle frame. The inner rotating cylinder is installed inside the upper cylinder and placed at the upper port of the base, with its outer side close to the inner wall of the upper cylinder. A ring of corrugated wall is fixedly connected to the bottom edge of the inner side of the inner rotating cylinder. The cross-section of the corrugated wall is a right-angled triangular structure. A ring of raised strips is fixedly connected in a circular array on the inclined surface of the corrugated wall. A cylindrical electromagnet is installed at the middle position of the bottom of the inner rotating cylinder. The outer side of the electromagnet is coated with waterproof adhesive. The collection basin is a basin-shaped structure with a circular through hole in the middle and the outer edge flares outward. A handle frame is fixedly connected to the upper end of the collection basin. The collection basin is fitted on the outside of the electromagnet. An annular groove is formed between the corrugated wall and the collection basin. Two drain holes are opened in this groove area, and a filter screen is installed at the port of the hole.

[0008] Wastewater discharge unit: installed inside the base.

[0009] The base and upper cylinder form the main frame of this device. The stepped structure at the connection between the two supports the inner rotating cylinder. The anode slag to be processed is poured into the inner rotating cylinder. When the inner rotating cylinder rotates, the slag is thrown towards the corrugated wall. The protrusions on the corrugated wall cause the slag to tumble continuously, thereby causing the slag adhering to the metal to fall off and separate. The water sprayed down from the upper side can wash the metal, thereby further cleaning the metal. When the electromagnet on the inner side is energized, it will form a magnetic force on its cylindrical surface, thereby attracting the cleaned metal. When the power is turned off and the magnet is demagnetized, the metal will fall into the collection basin. The collection basin can be lifted upwards by the handle frame to retrieve the recovered metal. The filter screen allows the cleaning wastewater to leak downwards and isolates the metal. The sewage discharge unit is used to discharge the cleaning wastewater, and the slag particles can be discharged to the outside along with the wastewater.

[0010] Furthermore, the metal recycling unit also includes a shower head, a pressurized water pump, a carrying frame, and a top cover. The upper end of the upper cylinder has a structure that is lower on the inside and higher on the outside, and a top cover is placed at the upper end. Two carrying frames are fixedly connected to the upper end of the top cover. A disc-shaped shower head is embedded in the middle area of ​​the top cover. A pressurized water pump is installed on the upper side of the shower head. The right side of the pressurized water pump has a water inlet port, and the water outlet port of the pressurized water pump is connected to the water inlet of the shower head. The top cover is used to seal the ports of the upper cylinder and the inner rotating cylinder to prevent slag, metal, and cleaning wastewater from splashing out from the ports. The pressurized water pump draws external water, pressurizes it, and sprays it from the lower end of the shower head to wash the anode slag. The carrying frames allow workers to easily open the top cover.

[0011] Furthermore, the metal recycling unit also includes a motor and a sleeve ring. The sleeve ring is fixedly connected to the lower side of the inner rotating drum. The motor is located inside the base, with its output shaft facing upwards and fixedly connected inside the sleeve ring. A pin is fixedly connected to the end of the output shaft. The sleeve ring is used to engage with the output shaft of the motor, and the pin ensures the stability of the transmission process. The motor provides power to drive the inner rotating drum to rotate.

[0012] Furthermore, the wastewater discharge unit includes a solenoid valve, a drain pipe, an inner partition, and a wastewater chamber. A drain pipe is inserted into the drain hole at the bottom of the inner rotating cylinder, and a solenoid valve is installed in the drain pipe. The base is hollow, and an inner partition is fixedly connected in the middle. The vertical cross-section of the inner partition is a convex shape. The motor is located inside the inner partition and is fixed to the base by bolts. The inner partition and the inner wall of the base are clamped together to form a wastewater chamber with interconnected upper and lower ends. The solenoid valve controls the opening and closing of the drain pipe. When the solenoid valve closes the drain pipe, the sprayed water accumulates inside the inner rotating cylinder, allowing the slag containing metal to be completely immersed in the water, thereby improving the cleaning cleanliness. Furthermore, with the help of water buoyancy, the washed-out metal objects can better float towards the electromagnet after being attracted by magnetic force. When the solenoid valve opens, the cleaning wastewater can flow into the wastewater chamber along the drain pipe. The inner partition is used to separate and protect the motor.

[0013] Furthermore, the wastewater discharge unit also includes a drainage channel, a second solenoid valve, and a drain outlet. A downward-sloping drainage channel is provided on one side of the bottom of the wastewater chamber. A drain outlet is inserted inside the drainage channel, with its end extending outwards. A second solenoid valve is installed in the drain outlet's pipe. The downward-sloping drainage channel facilitates the discharge of wastewater from the wastewater chamber, and the second solenoid valve controls the opening and closing of the drain outlet.

[0014] Furthermore, it also includes a control panel and a pressure relief valve. The pressure relief valve is installed on the upper side of the top cover, and the control panel is fixedly installed on the front end of the upper cylinder. The control panel is used to control the start and stop of the operation of various electrical devices in this device, and the pressure relief valve can release pressure inside the inner rotating cylinder during water injection.

When the power is turned off and the magnet is demagnetized, the metal will fall into the collection basin.

[0017] 2. Solenoid valve one is used to control the opening and closing of the drain pipe. When solenoid valve one closes the drain pipe, the sprayed water will accumulate inside the inner rotating drum, allowing the slag containing metal objects to be completely immersed in the water, thereby improving the cleanliness of the cleaning.

Solenoid valve 41 is used to control the opening and closing of the drain pipe 42. When solenoid valve 41 closes the drain pipe 42, the sprayed water will accumulate inside the inner rotating drum 31, so that the slag containing metal objects is completely immersed in the water, thereby improving the cleanliness of the cleaning. With the help of the buoyancy of the water, the washed metal objects can better float towards the electromagnet 33 after being attracted by the magnetic force.

[0035] The working principle of the metal recovery device for anode slag provided by this utility model is as follows: This device has a reliable metal recovery unit 3.

The pin block can ensure the stability of the transmission process. The motor 39 provides power to drive the inner rotating cylinder 31 to rotate. When the inner rotating cylinder 31 rotates, the slag is thrown towards the corrugated wall 32. The protrusions on the corrugated wall 32 will cause the slag to roll continuously, thereby causing the slag adhering to the metal to fall off and separate. The sprayed water can wash the metal objects, thereby further cleaning them. The pressurized water pump 38 draws water from an external source, pressurizes it, and sprays it from the lower end of the shower head 37 to wash the anode slag.

When solenoid valve 41 closes the drain pipe 42, the sprayed water accumulates inside the inner rotating drum 31, allowing the slag containing metal to be completely immersed in the water, thereby improving the cleanliness of the cleaning. Furthermore, with the help of water buoyancy, the washed-out metal objects, after being attracted by the magnetic force, can better float towards the electromagnet 33. When solenoid valve 41 is opened, the cleaning wastewater can flow along the drain pipe 42 into the sewage chamber 44. The inner partition 43 is used to separate and protect the motor 39. The downward-sloping drainage channel 45 facilitates the discharge of wastewater from the sewage chamber 44. Solenoid valve 46 controls the opening and closing of the drain outlet 47.
