Description

Technical Field

[0001] This utility model relates to the field of material separation, and in particular to an ultralight material separation device. Background Technology

[0002] In the solid waste treatment industry, there are many sheet-like and powdery materials with large differences in density and size but similar hydrodynamic properties. For example, the separation of lightweight materials such as wood chips and plastics from dust in construction and decoration waste treatment; the separation of separators and positive and negative electrode powders in the battery recycling industry. Efficient separation is required to recover valuable components.

[0003] The usual processing method is to first use an air classifier to separate the ultralight flake materials from the powder materials. The flake materials and powder materials then enter the downstream gravity separation system, where the ultralight flake materials and powder materials are separated.

[0004] Conventional gravity separation systems (such as cyclone dust collectors) cannot completely separate ultralight flakes from powders, and the separation effect needs to be improved. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides an ultralight material separation device.

[0006] The ultralight material separation device provided in this application adopts the following technical solution: An ultralight material separation device includes a housing. An air inlet channel communicating with the interior of the housing is provided on the top side wall of the housing. The air inlet channel is connected to and communicates with the air outlet of a preceding process. Ultralight materials enter the housing through the air inlet channel along with the airflow from the preceding process. An air outlet channel communicating with the interior of the housing is provided on the middle side wall of the housing. The air inlet channel and the air outlet channel are located on opposite sides of the housing. The air outlet channel is connected to and communicates with the air inlet of a subsequent device for processing powdery materials. A discharge channel communicating with the interior of the housing is provided on the bottom wall of the housing. The discharge channel is connected to and communicates with the inlet of a hopper for storing flake materials. A separation plate is fixedly installed inside the housing. The separation plate has filter holes. The size of the filter holes is larger than the size of the powder material and smaller than the size of the flake material.

The second flow space is connected to the air outlet channel. The first flow space and the second flow space are connected through the filter holes. The first flow space is located below the second flow space. Airflow carrying ultralight materials enters the first circulation space through the air inlet channel. Powdered materials pass through the filter holes of the separator plate with the airflow and then enter the downstream device for processing powdered materials through the air outlet channel. Flake materials cannot pass through the filter holes of the separator plate and enter the silo for storing flake materials through the discharge channel under the action of gravity.

The isolation section is inclined, with its highest end located above the air inlet channel and its lowest end located above the air outlet channel. The filter holes are located on the separation section, which is located at the air outlet channel, and the area of ​​the separation section is larger than the area of ​​the air outlet channel. The limiting section is arc-shaped, with a central angle ≥180°. Both ends of the limiting section are located on the same plane, and both ends of the limiting section are fixedly connected to the inner wall of the housing via connecting plates. The bottom of the limiting section is provided with a discharge port communicating with the discharge channel. The space formed below the isolation section, on the side of the separation section near the air inlet channel, and above the limiting section is the first circulation space; the space formed above the isolation section and on the side of the separation section near the air outlet channel is the second circulation space.

The scraper is fixedly connected to the end of the rotating blade away from the rotating shaft, and the other end of the scraper abuts against the inner circumferential surface of the limiting section.

[0009] Preferably, the plane containing the portion of the scraper outside the rotating blade has a certain angle with the plane containing the rotating blade.

[0010] Preferably, the rotating component includes a servo motor, which is coaxially connected to the rotating shaft via a right-angle reducer and drives the rotating shaft to rotate.

[0018] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0019] This application discloses an ultralight material separation device.

[0020] Reference Figure 1-4 The ultralight material separation device includes a housing 1. An air inlet channel 11, communicating with the interior of the housing 1, is located on the top side wall of the housing 1. The air inlet channel 11 is connected to and communicates with the air outlet of a preceding process (such as an air classifier). Ultralight materials enter the housing 1 through the air inlet channel 11 along with the airflow from the preceding process. An air outlet channel 12, communicating with the interior of the housing 1, is located on the middle side wall of the housing 1. The air inlet channel 11 and the air outlet channel 12 are located on opposite sides of the housing 1. The air outlet channel 12 is connected to and communicates with the air inlet of a subsequent device for processing powdered materials 7 (such as a pulverizing system). A discharge channel 13, communicating with the interior of the housing 1, is located on the bottom wall of the housing 1. The discharge channel 13 is connected to and communicates with the inlet of a silo for storing flake materials 8. Different raw materials and different processes require different subsequent processing methods; appropriate equipment can be connected according to the actual situation.

[0021] The opening of the air inlet channel 11 gradually widens from the direction away from the housing 1 to the direction closer to the housing 1. After the airflow enters the housing 1 through the air inlet channel 11, the gradually widening opening improves the efficiency of airflow entry. The opening of the air outlet channel 12 gradually narrows from the direction closer to the housing 1 to the direction farther away from the housing 1. After the airflow passes through the air outlet channel 12, the gradually narrowing opening facilitates the concentration and collection of airflow. The opening of the discharge channel 13 gradually narrows from the direction closer to the housing 1 to the direction farther away from the housing 1, facilitating the concentration and collection of sheet-like material 8.

[0022] A separation plate 2 is fixedly installed inside the housing 1. The separation plate 2 has filter holes 221. The size of the filter holes 221 is larger than the size of the powder material 7 and smaller than the size of the flake material 8. The separation plate 2 divides the space inside the housing 1 into a first flow space 3 and a second flow space 4. The first flow space 3 is connected to the air inlet channel 11 and the unloading channel 13. The second flow space 4 is connected to the air outlet channel 12. The first flow space 3 and the second flow space 4 are connected through the filter holes 221. The first flow space 3 is located below the second flow space 4.

[0023] Airflow carrying ultralight material enters the first circulation space 3 through the air inlet channel 11. Powdered material 7 passes through the filter holes 221 of the separation plate 2 with the airflow and then enters the downstream device for processing powdered material 7 through the air outlet channel 12. Flake material 8 cannot pass through the filter holes 221 of the separation plate 2. Under the action of gravity, flake material 8 enters the silo for storing flake material 8 through the unloading channel 13.

[0024] The separation plate 2 comprises, from top to bottom, an isolation section 21, a separation section 22, and a limiting section 23 connected sequentially from top to bottom. The isolation section 21 is inclined, with its highest end above the air inlet channel 11 and its lowest end above the air outlet channel 12. Filter holes 221 are located on the separation section 22. Neither the isolation section 21 nor the limiting section 23 has filter holes 221. The separation section 22 is located at the air outlet channel 12, and its area is larger than that of the air outlet channel 12. The limiting section 23 is arc-shaped, with a central angle ≥ 180° (in this embodiment, the central angle of the limiting section 23 = 180°). Both ends of the limiting section 23 are on the same plane, and both ends are fixedly connected to the inner wall of the housing 1 via connecting plates 231. The bottom of the limiting section 23 is provided with a discharge port 232 communicating with the discharge channel 13.

[0025] The space formed below the isolation section 21, on the side of the separation section 22 near the air inlet channel 11, and above the limiting section 23 is the first circulation space 3, and the space formed above the isolation section 21 and on the side of the separation section 22 near the air outlet channel 12 is the second circulation space 4.

[0026] A rotating impeller 5 is provided in the first circulation space 3. The rotating impeller 5 is rotatably arranged by the rotating assembly 6. The rotating impeller 5 includes a rotating shaft 51, rotating blades 52, and scraper 53. The rotating shaft 51 is rotatably connected to the housing 1 through a bearing. Multiple rotating blades 52 are equidistantly arranged along the circumference of the rotating shaft 51. There is a gap between the rotating blades 52 and the limiting section 23. The scraper 53 is fixedly connected to the end of the rotating blades 52 away from the rotating shaft 51. The other end of the scraper 53 abuts against the inner circumferential surface of the limiting section 23.

[0027] The plane of the scraper 53 located outside the rotating blade 52 has a certain angle with the plane of the rotating blade 52.

[0028] The rotating assembly 6 includes a servo motor 61, which is coaxially connected to the rotating shaft 51 via a right-angle reducer 62 and drives the rotating shaft 51 to rotate. The right-angle reducer 62 is fixed to the outer wall of the housing 1 via a connecting bracket.

[0029] The scraper 53 scrapes the ultralight material adhering to the separation plate 2 into the discharge port 232 and then into the silo through the discharge port 232 and the discharge channel 13.

[0030] The implementation principle of the ultralight material separation device in this application embodiment is as follows: Airflow carrying ultralight material enters the first circulation space 3 through air inlet channel 11. Powdered material 7 passes through the filter holes 221 of separation plate 2 with the airflow and enters the downstream device for processing powdered material 7 through air outlet channel 12. Flake material 8 cannot pass through the filter holes 221 of separation plate 2. Under the action of gravity, flake material 8 enters the silo for storing flake material 8 through discharge channel 13. Scraper 53 scrapes the ultralight material adhering to separation plate 2 into discharge port 232 and enters the silo from discharge port 232 and discharge channel 13.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
