Description

Technical Field

[0001] The utility model relates to the technical field of cleaning kettles, in particular to a separation device for separating oil and low-density small-particle powder. Background Art

[0002] Common cleaning methods for powders include dissolution filtration and spray cleaning. When the density of the powder is relatively large relative to the cleaning liquid, the powder and the cleaning liquid easily form a suspension. The impurities in the powder are dissolved by the cleaning liquid and filtered out. High-purity powder can be obtained by drying. When the density of the powder is relatively small relative to the cleaning liquid and the particles are large, the powder floats on the surface of the cleaning liquid. By spraying the cleaning liquid, the cleaning liquid can effectively wet the powder surface, dissolve the impurities and take them away. High-purity powder can be obtained by drying.

[0003] The powder has a lower density and smaller particles than the cleaning liquid. Such powder always floats on the surface of the cleaning liquid and moves in blocks. It cannot become a suspension and cannot be removed by dissolution and filtration. At the same time, the powder has a low density and small particles. When the spray method is used for cleaning, the powder is wrapped in a ball on the surface of the cleaning liquid. The cleaning liquid cannot effectively and smoothly enter the inside of the powder ball, and the spray method cannot effectively remove the impurities in it.

[0004] At present, there is no special cleaning device for powders with low density and small particles, and such powders are difficult to be effectively cleaned.

[0030] The utility model includes a kettle lid 1 and a kettle body 2. A filter screen 3 is installed inside the kettle body 2. The filter screen 3 divides the interior of the kettle body 2 into an upper chamber and a lower chamber up and down. A stirring blade 5 is provided in the lower chamber. The stirring shaft 6 of the stirring blade 5 sequentially passes upward through the filter screen 3 and is connected to the rotating shaft of a first motor 7 at the top of the kettle body 2 through a shaft sleeve. A liquid inlet 8 and a powder discharge port 9 communicating with the lower chamber are provided on the side wall of the kettle body 2. An oil discharge port 10 communicating with the upper chamber is further provided on the kettle lid. The kettle lid and the kettle body are detachably connected. A liquid inlet valve is installed on the liquid inlet 8, a powder discharge valve is installed on the powder discharge port 9, and an oil discharge valve is installed on the oil discharge port 10. It further includes a rotating plate 12. Assembly holes 13 are provided on the rotating plate 12. The kettle body 2 is detachably installed through a connecting member and the assembly holes 13. The design that the rotating plate 12 is fixed on a rotating device efficiently separates oil from low-density small-particle powder. Open the liquid inlet valve, and let the mixture of powder and oil enter the lower chamber of the kettle body 2 from the liquid inlet 8. Then pour the cleaning liquid into the liquid inlet 8. When the liquid level in the kettle body 2 is higher than the filter screen 3, start the first motor 7. The first motor 7 drives the stirring blade 5 to rotate. Under the action of the cleaning liquid, the oil floats above the filter screen 3, and the powder is separated below the filter screen 3. Open the oil discharge valve of the oil discharge port 10 to discharge the upper-layer oil and the cleaning liquid, and then close the oil discharge valve of the oil discharge port 10. Start the rotating device to invert the kettle body 2. Open the oil discharge valve of the oil discharge port 10 to let the cleaning liquid discharge from the oil discharge port 10. After the cleaning liquid is discharged, the purge port valve of the purge port 11 can be opened to blow in hot air, which flows out from the oil discharge port 10 to dry the powder. Close the oil discharge valve of the oil discharge port 10 and the purge port valve of the purge port 11. Open the powder discharge valve of the powder discharge port 9, and discharge the powder in the kettle body 2 from the powder discharge port 9 through the stirring blade 5.

The liquid inlet 8 being close to the filter net 3 facilitates rapid feeding. The liquid enters the upper chamber from the filter net 3, separating the powder from the oil. The powder discharge port 9 being close to the filter net 3 enables the stirring blade 5 to rotate and discharge the powder conveniently after the rotating plate rotates 180°.

[0034] The inner diameter of the kettle body 2 of the present utility model is larger than the height of the kettle body 2, increasing the stirring and filtering area, which can improve the cleaning effect and reduce the amount of cleaning liquid used.

[0035] As Figure 1 shown in the figure, the bottom of the kettle body 2 of this embodiment is provided with a purge port 11 communicating with the lower chamber. Wind can flow in from the purge port 11 and flow out from the oil discharge port 10 to achieve purging of the interior of the kettle body 2.

[0036] As Figure 1 shown in the figure, the ratio of the diameter of the powder discharge port 9 to the diameter of the liquid inlet 8 in this embodiment is 3:(1 - 2). Preferably, the ratio of the diameter of the powder discharge port 9 to the diameter of the liquid inlet 8 is 3:1, which can be adjusted according to actual conditions to accelerate the discharge of the powder.

[0037] As Figure 1 、 Figure 4 shown in the figure, the outer wall of the kettle body 2 of this embodiment is circumferentially provided with a flange edge 14. A plurality of mounting holes are arranged at intervals on the flange edge 14. The rotating plate 12 is provided with positioning holes 22 corresponding to the mounting holes one by one. It also includes a plurality of mounting bolts 15. Each mounting bolt passes through the mounting hole and the positioning hole 22 in sequence to fix the kettle body 2 on the rotating plate 12; this can fix the kettle body 2 and the rotating plate 12, facilitating installation and disassembly.

[0038] The stirring blade 5 of the present utility model is an S-shaped fan blade. Rotating along the direction of the S-shaped fan blade is beneficial to the discharge of the powder.

[0039] The present utility model further includes a hot air conveying mechanism. The hot air conveying mechanism is connected to the purge port 11 through a pipeline to convey hot air into the kettle body to dry the powder.

[0040] The hot air conveying mechanism of the present utility model includes a blower and a heating device connected to the blower.
