Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibration filtration equipment technology, specifically to an ultrasonic vibration filtration device for ceramic powder. Background Technology
[0002] Ceramic powders are typically made from inorganic compounds such as oxides (e.g., alumina, zirconium oxide), nitrides (e.g., silicon nitride), and carbides (e.g., silicon carbide) through processes like pulverization, grinding, and purification. Their particle sizes are mostly in the micrometer to nanometer range, and they are widely used in structural ceramics (e.g., wear-resistant bearings), functional ceramics (e.g., electronic ceramic substrates), and bioceramics (e.g., artificial bones). Because impurities can disrupt the structural uniformity of ceramic products, leading to reduced strength and cracks, and because powders of different mesh sizes exhibit significant differences in shrinkage and densification rates during sintering, it is necessary to perform vibration filtration for impurity removal and classification of ceramic powders.
[0003] When existing vibration filtration equipment processes high-viscosity slurries or ultrafine powders, particle agglomeration is caused by the close spacing between particles and strong van der Waals forces in high-viscosity slurries, and the difficulty in uniformly dispersing the dispersant. Ultrafine powders, on the other hand, tend to spontaneously aggregate due to their large specific surface area and high surface energy. Due to agglomeration and the poor fluidity of high-viscosity slurries, particles adhere to and accumulate at the edges of the sieve holes, leading to sieve blockage and making it impossible to effectively disperse particles and facilitate the passage of material through the sieve holes. Utility Model Content
[0004] The purpose of this invention is to provide a ceramic powder ultrasonic vibration filtration device to solve the above problems.
[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution, including:

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0031] like Figures 1-5As shown, in one embodiment, a ceramic powder ultrasonic vibration filtration device includes: a filtration assembly 3, including a first support rod 31 and a second support rod 32 arranged symmetrically. A collection frame 34 is installed at the bottom of the first support rod 31, and multiple sets of filter frames 37 are stacked on top of the collection frame 34 from bottom to top. A sealing cover 33 is installed on the top of the uppermost filter frame 37, thereby forming a relatively closed filtration space.
[0032] For example, the collection frame 34 is rotatably connected to the bottom outer wall of the first support rod 31 via the steering seat 36, so that the collection frame 34 can be flexibly rotated to adjust the angle; while the collection disc 35 is installed inside the collection frame 34 to receive the filtered ceramic powder.
[0033] Specifically, a collection tray 35 is installed inside the collection frame 34 to collect the filtered product for subsequent centralized collection of the filtered ceramic powder; a filter screen 38 is installed inside the filter frame 37 for graded filtration of the product; a sealing ring 39 is installed outside the filter screen 38 to enhance the sealing between the filter frames 37 and between the filter frames 37 and the sealing cover 33 and the collection frame 34, preventing unfiltered material from leaking out from the gaps.
[0034] Furthermore, the filter frame 37 is rotatably connected to the outer wall of the middle part of the first support rod 31 via the steering seat 36, and the filter screen 38 is rotatably connected to the filter frame 37 via the rotating shaft 311. The end of the rotating shaft 311 passes through the filter frame 37 and is equipped with a first retaining ring 310. The first retaining ring 310 is engaged with the second support rod 32 to fix the position of the filter screen 38. A handle 313 is installed on one side of the outer wall of the corresponding filter frame 37 and sealing cover 33 to facilitate the operator to rotate the filter frame 37 and sealing cover 33. A second retaining ring 312 is installed on the outer wall of the sealing cover 33 and is engaged with the second support rod 32 to fix the position of the sealing cover 33.
[0035] Specifically, both the first retaining ring 310 and the second retaining ring 312 are made into a semi-circular retaining ring structure that can be snapped together by the elastic element 23, which ensures the stability of the connection and allows the retaining ring to be easily removed from the support rod when disassembly is required.
[0036] It should be explained in detail that the filter screen 38 installed on the top filter frame 37 has a larger aperture than the filter screen 38 installed on the bottom filter frame 37. That is, the aperture of the filter screen 38 gradually decreases from top to bottom, thereby achieving the classification and screening of materials with different particle sizes.
[0037] In addition, the collection frame 34, filter frame 37 and sealing cover 33 are circular. The top contour of the collection frame 34 fits with the bottom contour of the filter frame 37, the outer contour of the adjacent filter frame 37 fits with the outer contour of the filter frame 37, the top contour of the filter frame 37 fits with the bottom contour of the sealing cover 33, and the outer contour of the sealing ring 39 fits with the inner contour of the filter frame 37. This can minimize the leakage of materials during the filtration process and further enhance the sealing performance inside the filter frame 37, ensuring that materials can only be filtered through the filter screen 38.
[0038] Understandably, the filter assembly 3 allows for the filtration of ceramic powder through multiple sets of filter screens 38 with gradually decreasing pore sizes. This enables graded filtration of ceramic powder based on different particle sizes or mesh counts, meeting diverse application needs. Furthermore, since both the filter frame 37 and the collection frame 34 employ a rotatable connection and are equipped with easy-to-operate handles 313, the various components can be quickly and conveniently rotated after filtration to collect ceramic powder of different particle sizes, providing ease of use.
[0039] Example 2:
[0040] Based on Embodiment 1, a support component 2 is also provided, including an ultrasonic vibration device 24 (such as an ultrasonic vibrator) installed below the filter component 3. The vibrating slide 25 drives the filter component 3 above to vibrate synchronously, thereby enhancing the filtration effect.
[0041] For example, the ultrasonic vibration device 24 is installed at the bottom of the slide 25, and the first support rod 31 and the second support rod 32 are symmetrically installed at the top of the slide 25.
[0042] Specifically, positioning rods 21 are symmetrically installed at the bottom of the slide 25, and the bottom of the positioning rods 21 is detachably connected to the base 1; correspondingly, an elastic element 23 (such as a support spring) is sleeved on the outside of the positioning rods 21, and a limiting seat 22 is installed on the top of the positioning rods 21.
[0043] It is understandable that with the support component 2, the ceramic powder can be vibrated by the ultrasonic vibration device 24 during the filtration operation of the filter component 3, and the filter component 3 can be used for filtration. At the same time, the slide 25 can move vertically back and forth along the outer wall of the positioning rod 21, thereby driving the elastic element 23 to perform low-frequency movement, effectively dispersing particles and promoting the material to pass through the sieve holes, thus effectively improving the vibration filtration efficiency of ceramic powder.
[0044] Working principle:
[0045] The ultrasonic vibration device 24 is electrically connected via an external power supply and controller. Before ultrasonically vibrating and filtering the ceramic powder, the following preparations are made: First, the handle 313 on the movable sealing cover 33 drives the second retaining ring 312 to disengage from the outer wall of the second support rod 32. Then, the sealing cover 33 is rotated open to disengage from the filter frame 37. Next, the ceramic powder to be filtered is added to the filter screen 38 on the inner wall of the uppermost filter frame 37. Then, the handle 313 on the movable sealing cover 33 drives the second retaining ring 312 to engage with the outer wall of the second support rod 32. Finally, the sealing cover 33 is snapped onto the outer surface of the second support rod 32 to seal the uppermost filter frame 37.
[0046] The ultrasonic vibration device 24 is then activated and begins to work, while the slide 25 vibrates on the surface of the positioning rod 21. The positioning rod 21 moves vertically back and forth and synchronously drives the elastic element 23, which remains active under the elastic action of the elastic element 23. When the slide 25 is vibrating at a low frequency, it synchronously drives the first support rod 31 and the second support rod 32 to move synchronously, thereby driving the ceramic powder placed inside the filter frame 37 to gradually pass through the filter screen 38 for sieving. This allows the powder to be gradually sieved and filtered downwards according to different particle sizes until the smallest powder falls into the collection frame 34 and the collection tray 35 for storage.
[0047] After the ceramic powder is filtered, from top to bottom, the handle 313 on the movable filter frame 37 drives the first retaining ring 310 to disengage from the outer wall of the second support rod 32, and the filter frame 37 drives the steering seat 36 to rotate on the outer wall of the first support rod 31. Then, the collection container is placed on the bottom of the rotated filter frame 37, and the corresponding first retaining ring 310 drives the rotating shaft 311 and the filter screen 38 to rotate, thereby driving the sealing ring 39 to rotate in the inner wall of the corresponding filter frame 37, so that the ceramic powder on the surface of the filter screen 38 tilts downward and pours out. The above operation is repeated to complete the collection of ceramic powder of different particle sizes.
[0048] Finally, by rotating the handle 313 on the collection frame 34, the collection tray 35 placed in the collection frame 34 is removed, thus completing the collection of all the ceramic powder after vibration filtration.
[0049] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
