Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of building ceramic powder dispersing equipment, and in particular to an ultrasonic vibration powder distribution device for wetting and powdering building ceramics. Background Technology
[0002] Currently, both dry powder production technology and the upgraded wet powder production technology for architectural ceramics face the problem of uniform powder distribution during granulation or wetting. In particular, the wet powder production method improves upon the dry powder production method by employing multi-stage blowing powder distribution and forced perforated plate mechanical dispersion, thus achieving a significant improvement in powder distribution uniformity compared to the previous dry powder distribution method.
[0003] Because the new multi-stage powder distribution method still relies on wind to disperse and move fine powder, large-diameter perforations are necessary to ensure smooth powder drop from the perforated plate. This results in localized concentration of falling fine powder, insufficient uniform dispersion, and requires a powerful fan to provide air pressure and volume, necessitating a corresponding increase in the size of the system's dust collector and adding to the complexity and investment of the powder distribution structure. Furthermore, the mixture of wind and powder has strong wind erosion properties, making the perforated plate highly susceptible to wind erosion damage. Additionally, the high density of ceramic fine powder and its significant free-fall state within the tower make wind dispersion difficult. Therefore, finding a windless, uniform powder distribution method in the wetting system has become a key issue for improving and advancing wetting powder preparation technology. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0019] Reference Figures 1 to 3 As shown, this embodiment provides an ultrasonic vibration powder distribution device for wetting and powdering building ceramics, including an upper powder-blocking ring 3, a lower powder-blocking ring 4 below the upper powder-blocking ring 3, a filter element installed between the upper powder-blocking ring 3 and the lower powder-blocking ring 4, a plurality of ultrasonic vibration components circumferentially connected to the outer side of the filter element, a primary powder distribution inverted cone 12 provided above the filter element, the primary powder distribution inverted cone 12 being fixedly connected to the inner wall of the upper powder-blocking ring 3, a sealing cover 2 being fixedly connected to the top of the upper powder-blocking ring 3, a powder inlet flexible interface 1 being fixedly connected and connected to the top of the sealing cover 2, and a powder outlet flexible interface being provided at the bottom of the lower powder-blocking ring 4.
[0020] This invention satisfies the process requirements of vibration and stable powder supply of the powder distributor by setting up the powder inlet flexible interface 1 and the sealing cover 2; the design of the primary powder distribution inverted cone 12 allows fine powder to fall through the inverted cone mesh and flow down the cone surface at the same time, so that the fine powder distribution is initially uniform; the ultrasonic vibration component provides vibration energy to the filter element for secondary powder distribution, which further improves the uniformity of powder distribution; by setting the powder outlet flexible interface at the lower end of the lower powder baffle ring 4, a flexible connection is achieved between it and the wetting tower body, so as to ensure that the fine powder distributed by the powder distributor falls directly into the cylinder without dust; the ultrasonic vibration component causes the filter element to vibrate at a small amplitude ultra-high frequency, thereby ensuring the uniformity of powder distribution.
[0021] Specifically, the upper powder baffle ring 3 is welded together with the sealing cover 2 and the first-stage powder distribution inverted cone 12 to form a stable cabinet frame structure to meet the needs of high-frequency vibration. The hole diameter and hole spacing of the first-stage powder distribution inverted cone 12 are selected as 20mm. Soft interface retaining rings are welded at the powder inlet soft interface 1 and the powder outlet soft interface to facilitate closed operation of powder inlet and outlet.
[0022] Further refining the scheme, the ultrasonic vibration component includes a transducer 8 fixedly connected to the filter element, and the transducer 8 is connected to an ultrasonic generator 6 via a wire. The ultrasonic generator 6 is located on one side of the lower powder ring 4.
[0023] Further refining the design, the filter element includes a screen 13, with a screen frame 7 fixedly connected to the outside of the screen 13. An upper powder-blocking ring 3 and a lower powder-blocking ring 4 respectively contact the screen frame 7, and a transducer 8 is fixedly installed on the outside of the screen frame 7. The upper powder-blocking ring 3, the lower powder-blocking ring 4, and the screen frame 7 are made of stainless steel, with a designed height of approximately 200mm.
[0024] The design is further refined by installing several clamps 9 on the outer side of the sieve frame 7. The clamps 9 are fixedly connected to the upper powder blocking ring 3 and the lower powder blocking ring 4 by bolts. By fixing the sieve frame 7 and the sieve screen 13 in the middle of the upper powder blocking ring 3 and the lower powder blocking ring 4, the sieve screen 13 is selected from 10 to 20 mesh stainless steel coarse sieve screen, and they are connected together by the clamps 9, achieving a uniform effect of secondary powder distribution.
[0025] Specifically, the powder is locked by the upper powder-blocking ring 3 and the lower powder-blocking ring 4. The upper powder-blocking ring 3 and the lower powder-blocking ring 4 are connected and fixed to the sieve frame 7 by the clamp 9. The sieve screen 13 for powder distribution is installed taut on the upper part of the sieve frame 7 to ensure that the ultrasonic vibration energy is transmitted evenly. The edge of the sieve screen 13 is installed with a resonant ring, which is connected to the transducer 8 to convert the longitudinal vibration into the transverse vibration of the sieve screen 13, forming a three-dimensional vibration effect. The transducer 8 converts electrical energy into mechanical vibration, generating high-frequency micro-amplitude vibration. The transducer 8 is connected to the ultrasonic generator 6, which converts the power frequency electricity into a high-frequency electrical signal to provide energy for the transducer 8, so that the fine powder is evenly dispersed and distributed. The number of ultrasonic generators 6 used can be selected according to the amount of powder and the diameter of the powder-blocking ring.
[0026] To further refine the design, a reinforcing rod 14 is installed at the bottom of the screen 13, and the reinforcing rod 14 is fixedly connected to the inner wall of the screen frame 7. The installation of the reinforcing rod 14 increases the load-bearing capacity of the screen 13, making the screen 13 less prone to damage and extending its service life.
[0027] Further refining the design, a fixed frame 5 is fixedly connected to the side wall of the lower powder baffle ring 4, and a fixed ring frame 11 is set below the lower powder baffle ring 4. Several damping shock-absorbing springs 10 are set between the fixed ring frame 11 and the fixed frame 5. The fixed frame 5 is designed at the lower end of the lower powder baffle ring 4 for the installation of the damping shock-absorbing springs 10. At the same time, a 100mm powder outlet flexible interface is welded along the inner ring for the flexible connection and locking of the cloth bag. Both the fixed ring frame 11 and the fixed frame 5 are made of thick annular square steel. The design of using damping shock-absorbing springs 10 to support the bottom of the fixed ring frame 11 and the relatively dense single damping shock-absorbing springs 10 is designed to solve the stability problem of the large size of the powder distribution cabinet and reduce the impact on the high-altitude columns.
[0028] This invention transforms the sieving function of screen 13 into a uniform powder distribution function using ultrasound. Utilizing the smaller amplitude and higher frequency of ultrasound, the diameter of the screen holes is increased when used as a sieve. The design of the residue outlet and the collection of undersize fine powder are disregarded, allowing powder to flow directly through the cross-section of screen 13, achieving a uniform powder distribution effect. This device can simultaneously replace the cylindrical diffuser, inverted cone diffuser, and perforated plate diffuser designs in the previous three-stage powder distribution system for wet powder making. It also eliminates the need for a blower system for these three stages of powder distribution, thus simplifying the structure, reducing power consumption, and improving the uniformity of powder distribution. This fully guarantees the quality of wetting in wet powder making. Correspondingly, the configuration of the dust collector, constant pressure exhaust hood, and airlock cone in the wet powder making system is also omitted or reduced, resulting in a simpler structure, lower failure rate, reduced operating costs, and improved powder production, quality, and economic efficiency.
