Description

Technical Field

[0001] This utility model relates to the field of lithium battery solid waste recycling technology, specifically a mixing device for solid waste recycling. Background Technology

[0002] Solid waste from lithium batteries mainly refers to waste lithium battery components generated during industrial production activities, including waste electrode sheets, waste cells, waste powder and slurry, and scraps. It is classified as recyclable solid waste. When recycling solid waste from lithium batteries, a mixing device for solid waste recycling is required. Mixing solid waste from lithium batteries refers to mixing solid waste from waste batteries with new materials in a certain proportion during the recycling and processing of waste lithium batteries in order to achieve resource reuse.

[0003] The existing Chinese patent CN216799828U, published on June 24, 2022, discloses a decolorizing reactor for producing industrial-grade mixed oil using biological waste. This invention relates to the field of decolorizing reactor technology. An exhaust fan is installed on the upper surface of the reactor, and an air duct extending into the reactor is installed at the input end of the exhaust fan. A first solenoid valve is installed on the air duct near the reactor. The running exhaust fan extracts water vapor from inside the reactor through the air duct and then delivers it to a condenser for condensation through an output pipe. This quickly removes water vapor accumulated on the upper part of the reactor, preventing it from condensing into water droplets on the top surface and falling into the mixed oil, thus shortening the dehydration time of the mixed oil. The use of bolt holes and bolt seats allows the heating rod to be installed on the lower surface of the bolt seat. The bolt seat can be reversed to unscrew it from the bolt hole, allowing the heating rod to be removed from the reactor. This makes the heating rod easy to install and remove, facilitating maintenance and replacement, and extending the service life of the device.

[0004] However, in actual use, when the above-mentioned device is used to add materials to the reactor, the solid waste of lithium batteries and new materials are added through the feed pipe. During the addition, the materials cannot be effectively and evenly dispersed. The materials will accumulate in one place under gravity. This results in a problem that it takes a long time to mix the materials evenly.

[0005] Therefore, we propose a novel mixing device for solid waste recycling to solve the above-mentioned technical problems. Utility Model Content

[0034] Example 1

[0035] This embodiment provides a technical solution: a mixing device for solid waste recycling, such as... Figures 1-5 As shown, it includes a lithium battery solid waste mixing tank, a mixing and stirring mechanism, a rotary crushing mechanism, a feeding pipe 4, and an airflow uniform dispersion mechanism.

[0036] The mixing and stirring mechanism is installed and connected to the inner middle of the lithium battery solid waste mixing tank. This mechanism mixes and stirs the recycled lithium battery solid waste material inside the tank. A rotating crushing mechanism is fixedly connected to the upper left side of the mixing tank. This mechanism crushes the lithium battery solid waste material to the required mixing size before adding it to the mixing tank. A feeding pipe 4 is installed on the upper end of the rotating crushing mechanism via screws. The feeding pipe 4 allows the lithium battery solid waste material to be added to the mixing tank. The material is added to the rotary crushing mechanism for crushing. The airflow uniform dispersion mechanism is fixedly connected to the lithium battery solid waste mixing tank and can be stably installed. The airflow uniform dispersion mechanism is connected to the rotary crushing mechanism. The airflow uniform dispersion mechanism can blow the material inside the rotary crushing mechanism. The airflow uniform dispersion mechanism can receive gas delivered by an external air pump to blow the material. By delivering gas of different pressures by an external air pump, the blown lithium battery solid waste can be dispersed to different areas. This allows for uniform addition of material for mixing, which is convenient for efficient mixing in the later stages.

[0037] like Figure 1 and Figure 5 As shown, the lithium battery solid waste mixing vessel includes a reactor body 1. The reactor body 1 is hollow inside and can store lithium battery solid waste and new materials for mixing. An observation window 11 is fixedly connected to the middle of the front end of the reactor body 1 to facilitate personnel to observe the mixing status. A discharge valve body 2 is fixedly connected through the middle of the lower end of the reactor body 1. After mixing inside the reactor body 1, the discharge valve body 2 is opened to facilitate material discharge. Three equally angled reactor body support columns are fixedly connected to the outside of the discharge valve body 2 on the reactor body 1. The reactor body 1 is stably supported by the triangularly distributed support columns 12 at the lower end. An exhaust sealing cover 13 is installed on the inner side of the upper end of the reactor body 1 by screws. The exhaust sealing cover 13 can effectively seal the upper opening of the reactor body 1. The exhaust pipe on the exhaust sealing cover 13 can be connected to the purification tower for waste gas purification. A mixing and stirring mechanism is installed at the center of the inner side of the exhaust sealing cover 13. The mixing and stirring mechanism can be started on the exhaust sealing cover 13 for mixing.

[0038] The mixing mechanism includes a stirring motor 3, which is mounted on the exhaust sealing cover 13 with screws for easy installation and removal. The output shaft of the stirring motor 3 is fixedly connected to a first coupling 31 arranged along the central axis of the exhaust sealing cover 13. When the output shaft of the stirring motor 3 rotates, it can drive the first coupling 31 to rotate. The other end of the first coupling 31 is fixedly connected to a mixing main shaft 33. When the first coupling 31 rotates, it can drive the mixing main shaft 33 to rotate. Eight mixing side rods 32 are symmetrically fixedly connected to the outer wall of the mixing main shaft 33 and sleeved inside the reactor body 1. The mixing main shaft 33 can drive the eight mixing side rods 32 symmetrically fixed to the outer wall to rotate. The eight mixing side rods 32 can rotate and mix inside the reactor body 1. The mixing main shaft 33 is concentric with the reactor body 1 to avoid rotational position deviation.

[0039] During use, lithium battery solid waste can be added to the rotary crushing mechanism through the feeding pipe 4 for crushing. The rotary crushing mechanism crushes the lithium battery solid waste, and the crushed material meets the mixing size requirements. The airflow uniform dispersion mechanism is fixedly connected to the lithium battery solid waste mixing tank and can be stably installed. The airflow uniform dispersion mechanism is connected to the rotary crushing mechanism and can blow the material inside the rotary crushing mechanism. The airflow uniform dispersion mechanism can receive gas delivered by an external air pump to blow the material. By delivering gas of different pressures by an external air pump, the blown lithium battery solid waste can be dispersed to different areas, so that the material can be added evenly for mixing, which is convenient for efficient mixing later. The mixing and stirring mechanism can stir and mix the lithium battery solid waste inside the lithium battery solid waste mixing tank.
