Description

Technical Field

[0001] The utility model relates to a screening and filtering device, in particular to an alumina ceramic powder screening and filtering device applied in the technical field of ceramic powder screening and filtering. Background Art

[0002] During the production process, ceramic powder needs to be screened using vibrating screening equipment to obtain powder coatings with uniform particles. When traditional screening equipment is screening, ceramic powder is prone to accumulation and clogging in the screening components, which can easily cause damage to the screen and affect the screening efficiency. The existing technology still has inconveniences and defects in actual use, so it is necessary to improve the ceramic powder screening and filtration equipment.

[0003] The patent with publication number CN210876214U discloses a filtering and screening device for powdered materials, including a box body, a feed funnel fixedly connected to the top of the box body, and a support foot fixedly connected to the bottom of the box body. The filtering and screening device for powdered materials pours powdered materials of different sizes into the box body through the feed funnel, and the powdered materials will fall above the screening plate. The first connecting plate is driven to vibrate by the first vibration motor. During the shaking process of the first connecting plate, the screening frame and the screening plate are driven to vibrate in turn, so that the powdered material on the screening plate is filtered and screened. The powdered material with a volume smaller than the aperture of the screening hole will fall above the filter plate through the screening hole, and the larger powdered material will flow into the interior of the first collection box through the first discharge pipe.

The ceramic powder filtered by the first filter plate enters the second frame, and the vibration motor controls the second filter plate to vibrate up and down to shake off the large-particle ceramic powder not filtered out by the first filter plate, and enters the third frame after being filtered through the second filter plate. The large-particle impurities that are not filtered out are discharged from the screening and filtering device through the feed port two. The control motor controls the filter plate to perform pressure grinding and filtering on the ceramic powder entering the third frame and discharge it from the screening and filtering device through the feed port three. At the same time, the fine ceramic powder is filtered through the filter net and transported into the collection frame for storage.

[0008] As a further improvement of the present application, feed port 1 passes through the cavity inside the first frame, feed port 2 passes through the second frame, feed port 3 passes through the third frame, and a material taking port is provided on one side of the collection frame.

The ceramic powder filtered by the first filter plate enters the second frame, and the vibration motor arranged on the top of the fixed plate controls the second filter plate to vibrate up and down, so as to remove the large particles of ceramic powder that are not filtered out by the first filter plate. The powder is not shaken up and is filtered through the second filter plate before entering the third frame. The large particles of impurities that are not filtered out are discharged from the screening and filtering device through the second feed port set on the side of the second frame, which plays a role in further refining the filtration and screening. The control motor installed at the bottom of the fixed plate controls the filter plate to perform pressure grinding and filtering on the ceramic powder entering the third frame and discharge it from the screening and filtering device through the third feed port. At the same time, the fine ceramic powder is filtered through the filter mesh and then transported into the collection frame for storage. This design can effectively break up the compacted powder material, while alleviating the waste of resources caused by multiple filtration and screening, thereby improving the collection efficiency and production quality.

[0027] Second implementation method:
