[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] Example: Figure 1 As shown, the OLED organic material mechanical impurity removal device of this embodiment includes a housing 1 and a support 2 disposed at the bottom of the housing 1. The housing 1 is provided with a partition 11. A stirring chamber 111 is formed above the partition 11, and a filtering chamber 112 is formed below the partition 11. A magnetic stirring unit 3 is provided in the stirring chamber 111. A heating unit 4 for heating the stirring chamber 111 is provided in the partition 11. A drain port is provided on the partition 11, and a control valve 5 is provided in the drain port. A filtering unit 6 is provided at the top of the filtering chamber 112, and a solution discharge port 113 with a valve is provided at the bottom of the filtering chamber 112. An organic material inlet 12 is provided at the top of the housing 1, and a solvent addition port 13 is also provided at the top of the housing 1.

[0025] In this embodiment, the OLED organic material mechanical impurity removal device involves adding powdered OLED organic material through the organic material inlet 12, followed by adding a solvent (all existing solvents, not detailed here) through the solvent addition port 13. Then, the magnetic stirring unit 3 is activated to stir the solvent and organic material powder, while the heating unit 4 heats the stirring chamber 111. Under suitable temperature conditions, the organic material powder is completely dissolved in the solvent. The stirring process accelerates the dissolution of the organic material. Simultaneously, due to the characteristics of the magnetic stirring unit 3, metallic impurities in the solution are adsorbed during stirring. Next, the control valve 5 is opened, allowing the solution to flow downwards. Insoluble impurities are filtered out by the filtration unit 6, and the remaining solution enters the lower part of the filtration chamber 112 and is finally discharged through the solution outlet 113 for further crystallization, drying, and other operations, resulting in purified organic material powder. The overall structure is simple and reasonable, effectively removing metallic and other mechanical impurities from organic materials with minimal manual intervention and high efficiency.

[0026] In this embodiment, the magnetic stirring unit 3 includes at least the following two structural forms:

[0027] 1) The magnetic stirring unit 3 includes a stirring shaft 31, a cross-shaped connecting frame 32, and multiple stirring rods 33. The stirring shaft 31 is vertically arranged, and its upper end is rotatably connected to the middle of the housing 1. The upper end of the housing 1 is provided with a rotary drive device 35 connected to the upper end of the stirring shaft 31. The connecting frame 32 is horizontally arranged, and its cross intersection is connected and fixed to the lower end of the stirring shaft 31. Multiple stirring rods 33 are vertically fixed at even intervals to the lower end of the connecting frame 32. The stirring rods 33 are magnetic rods.

[0028] In the above scheme 1), the rotary drive device 35 drives the stirring shaft 31 to rotate the cross-shaped connecting frame 32, thereby causing multiple stirring rods 33 to stir the solution. Since the stirring rods 33 are smooth magnetic rods (which can be made of permanent magnets), they come into full contact with the solution during the stirring process and adsorb metal impurities in the solution.

[0029] 2) The magnetic stirring unit 3 includes a stirring shaft 31, a cross-shaped connecting frame 32, and multiple stirring rods 33. The stirring shaft 31 is vertically arranged, and its upper end is rotatably connected to the middle of the housing 1. The upper end of the housing 1 is provided with a rotary drive device 35 connected to the upper end of the stirring shaft 31. The connecting frame 32 is horizontally arranged, and its cross intersection is connected and fixed to the lower end of the stirring shaft 31. Multiple stirring rods 33 are vertically fixed at even intervals to the lower end of the connecting frame 32. Multiple sets of adsorption components 34 made of permanent magnets are arranged at intervals on the surface of the stirring rods 33.

[0030] In the above scheme 2), the rotary drive device 35 drives the stirring shaft 31 to rotate the cross-shaped connecting frame 32, thereby causing multiple stirring rods 33 to stir the solution, so that the organic material powder dissolves in the solution at a certain temperature. During the stirring process, multiple sets of adsorption components 34 come into full contact with the solution and then adsorb insoluble metal impurities in the solution. This design can effectively remove metal impurities.

[0031] In this embodiment, the top of the box body 1 is provided with a box cover that can be opened or closed. The magnetic stirring unit 3 is connected to the box cover. The box cover can be connected to the upper end of the box body 1 by a latch or the like, so that the inside of the box body 1 and the magnetic stirring unit 3 can be cleaned after opening.

[0032] In this embodiment, the rotary drive device 35 uses a servo motor of an appropriate model.

[0033] In this embodiment, the adsorption component 34 is tree-branch shaped.

[0034] In this embodiment, the upper surface of the partition 11 is a conical surface, and the drain outlet is provided at the tip of the cone. The conical design facilitates the convergence of liquid towards the drain outlet, making drainage easier.

[0035] In this embodiment, the heating unit 4 is an electric heating wire or an electric heating tube. An electrical cabinet is provided on the outside of the housing 1. This electrical cabinet is connected to the heating unit 4 and the rotary drive device 35, allowing operation of both from the electrical cabinet. The control valve 5 can be configured as an electrically controlled valve, connected to the electrical cabinet for electronic control.

[0036] As a preferred implementation method, such as Figure 2 As shown, the organic material inlet 12 extends upward to form a tube. Multiple sets of horizontal rotating cylinders 14 are rotatably arranged between the inner walls on both sides of the organic material inlet 12. The surface of the rotating cylinder 14 is provided with densely distributed comb strips. The comb strips are used to intercept light impurities, such as hair. Multiple sets of rotating cylinders 14 are distributed in parallel at intervals on the same horizontal plane.

[0037] In the above implementation scheme, when organic material powder is added through organic material inlet 12, the powder flows through the comb gaps on the surface of the rotating drum 14, and light impurities (such as hair) are intercepted at the comb, thus achieving preliminary filtration of the powder.

[0038] In a preferred embodiment, the filter unit 6 is a filter cloth bag fixed on the inner wall of the filter cavity 112.

[0039] In the above implementation scheme, the filter unit 6 has a simple structural design. A perforated metal bracket can be installed on the outside (lower part) of the filter cloth bag for support. This metal bracket can be installed on the inner wall of the filter chamber 112, thus providing good support for the filter cloth bag.

[0040] In this embodiment, an inspection port is provided on the side wall of the filter chamber 112 at a position corresponding to the position above the filter cloth bag, and an inspection door that can be opened or closed is installed at the inspection port. This facilitates opening the inspection door and using the inspection port for internal inspection and cleaning.

[0041] In a preferred embodiment, the inner wall of the filter chamber 112 is provided with a ring of spaced hanging points, and the edge of the filter cloth bag is provided with hooks that correspond one-to-one with the hanging points, and the hooks are hung at the corresponding hanging points.

[0042] In the above implementation scheme, the hanging point can be a hanging ring, and the filter cloth bag is attached to the hanging point for easy replacement of the filter cloth bag.

[0043] In this embodiment, the bottom of the support 2 is provided with wheels 21, which facilitates the movement of the entire device along the ground.
