Description

A waste battery toner separation device Technical Field

[0001] This utility model provides a waste battery toner separation device, belonging to the technical field of waste battery processing devices. Background Technology

[0002] A battery is a device that converts chemical energy into electrical energy. It generates current through internal chemical reactions to provide portable power for various electrical appliances and devices. It consists of key components such as a positive electrode, a negative electrode, an electrolyte, and a separator. Common types include lithium-ion batteries, lead-acid batteries, and nickel-metal hydride batteries.

[0003] After recycling used batteries, in order to recover high-value materials and realize resource reuse, they are shredded and then crushed, followed by multi-layer physical screening. The value of a battery is determined by the metal elements attached to its positive and negative electrodes. The mixture of raw materials after battery crushing is called black powder in the industry. It is the core value of the battery. This mixture contains various metals, carbon powder, graphite, etc.

[0004] Currently, when using high-temperature pyrolysis to separate carbon powder from black powder, tubular furnaces or rotary kilns are mainly used to hold the black powder. However, the black powder is piled up together in this way, resulting in low heating efficiency. The black powder after external pyrolysis will affect the pyrolysis rate of the black powder inside, resulting in a slow pyrolysis process. Summary of the Invention

[0005] The technical problem this invention aims to solve is the low efficiency of extracting carbon powder from black powder using the current high-temperature pyrolysis method.

[0006] In order to solve the above problems, the proposed technical solution is as follows: a waste battery toner separation device, including a tubular furnace, an inert gas supply mechanism connected to the tubular furnace, and a volatile gas condensation and collection mechanism; an output shaft of an electric motor passing through the tubular furnace is provided in the upper middle part of the tubular furnace, and an auger blade 1 is provided in the lower middle part of the output shaft of the electric motor, and the outer edge of the auger blade 1 is connected to the auger blade 2.

[0007] As an improvement, the tubular furnace includes a furnace body and a furnace cover disposed above the furnace body;

[0008] As an improvement, the inert gas supply mechanism includes a gas pipe with its outlet end connected to the tubular furnace, a gas pipe with its inlet end connected to a gas cylinder, and a one-way valve at the outlet end of the gas pipe.

[0009] As an improvement, the volatile gas condensation and collection mechanism includes a condenser tube connected to the tubular furnace and a collection box connected to the condenser tube.

[0010] As an improvement, the bottom of the auger blade 1 is attached to the inner bottom surface of the furnace body and the outer edge is inclined downward;

[0011] As an improvement, the bottom of the second auger blade is attached to the inner bottom surface of the furnace body and the outer edge is attached to the inner wall of the tubular furnace, with the inner edge tilted downward.

[0012] The beneficial effects of this utility model are:

[0013] By setting an electric motor to drive the first auger blade to rotate, and the first auger blade to drive the second auger blade to rotate, when using the high-temperature pyrolysis method to separate carbon powder, the first auger blade can move the black powder placed near the middle of the tube furnace outward, and the second auger blade can move the black powder placed near the outer part of the tube furnace inward. This enables the black powder to be heated quickly and evenly, thereby improving the pyrolysis rate of the black powder. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] As shown in Figures 1-3, this utility model provides a waste battery toner separation device, including a tubular furnace 1; the tubular furnace 1 includes a furnace body 101 and a furnace cover 102 disposed above the furnace body 101; the tubular furnace 1 is an existing device that can provide a stable high-temperature environment to heat the "black powder" produced after the waste battery is crushed. The heating temperature is generally selected between 500℃ and 900℃. This temperature range is sufficient to volatilize most organic matter and some low-boiling-point inorganic matter without damaging the graphite structure.

[0020] An inert gas supply mechanism 2 is connected to the tubular furnace 1. The inert gas supply mechanism 2 includes a gas pipe 201 with its outlet end connected to the tubular furnace 1, a gas cylinder 202 with its inlet end connected to the gas pipe 201, and a one-way valve at the outlet end of the gas pipe 201. When the valve of the gas cylinder 202 is opened, the inert gas will enter the tubular furnace 1 through the gas pipe 201. When heating the carbon powder, it can prevent the carbon powder from being oxidized at high temperature and ensure that the entire pyrolysis process is carried out in an oxygen-free environment.

[0021] The volatile gas condensation and collection mechanism 3 of the tube furnace 1 is connected; the volatile gas condensation and collection mechanism 3 includes a condenser 301 connected to the tube furnace 1 and a collection box 302 connected to the condenser 301; in this way, during the pyrolysis process, non-carbon components such as electrolyte residues, binders, and certain metal compounds will volatilize into gases at high temperatures. The volatilized gases are cooled by the condenser 301 and then enter the collection box 302. This part mainly includes organic solvents, electrolyte decomposition products, etc., while the unvaporized solid residues are mainly carbon powder (graphite) and other high-temperature resistant inorganic substances.

[0022] A motor 4 with an output shaft passing through the upper center of the tube furnace 1 is provided. A screw conveyor blade 5 is provided in the lower middle part of the output shaft of the motor 4. The outer edge of the screw conveyor blade 5 is connected to the screw conveyor blade 6. The bottom of the screw conveyor blade 5 is attached to the inner bottom surface of the furnace body 101 and the outer edge is inclined downward. The bottom of the screw conveyor blade 6 is attached to the inner bottom surface of the furnace body 101 and the outer edge is attached to the inner wall of the tube furnace 1, and the inner edge is inclined downward. In this way, during the pyrolysis process, the motor 4 can drive the screw conveyor blade 5 to rotate, and the screw conveyor blade 5 can drive the screw conveyor blade 6 to rotate. The screw conveyor blade 5 can move the black powder in the middle of the tube furnace 1 outward, and the screw conveyor blade 6 can move the black powder in the outer part of the tube furnace 1 inward, thereby enabling the black powder to be heated quickly and evenly, thus improving the pyrolysis rate of the black powder.

[0023] The principle of this invention is as follows: In use, the black powder is first placed into the tube furnace 1. Then, the valve of the gas cylinder 202 is opened, allowing the inert gas in the cylinder 202 to enter the tube furnace 1 through the gas pipe 201, filling the tube furnace 1 with inert gas. Next, the tube furnace 1 and the motor 4 are started. The tube furnace 1 heats the black powder, causing non-carbon components such as electrolyte residues, binders, and certain metal compounds in the black powder to volatilize into gas. The volatilized gas is cooled through the condenser 301 and then enters the collection box 302. This part mainly includes organic solvents and electrolyte decomposition products, while the unvaporized solid residues are mainly carbon powder (graphite) and other high-temperature resistant inorganic substances. During the pyrolysis process, the motor 4 drives the auger blades 5 to rotate. 5 can drive the auger blades 6 to rotate. The auger blades 5 can move the black powder in the middle of the tube furnace 1 outward, and the auger blades 6 can move the black powder in the outer part of the tube furnace 1 inward. This enables the black powder to be heated quickly and evenly, thereby improving the pyrolysis rate of the black powder. The residue after pyrolysis usually still contains some fine inorganic particles or other impurities. These large particles that are insoluble in water or solvents can be removed by filtration. The filtered carbon powder is then washed with an appropriate solvent (such as water, acid solution, etc.) to remove impurities adsorbed on the surface and improve purity. The final step is to dry the washed carbon powder to remove residual moisture and other solvents, ensuring that the final product is dry, pure, and suitable for subsequent applications.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
