Description

Technical Field

[0001] This utility model belongs to the field of building ceramic wetting and powder preparation technology, and particularly relates to a high-frequency vibration powder preparation device for 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 powder distribution, thus achieving significant progress and improvement in powder distribution uniformity compared to the previous dry powder production method.

[0003] However, the multi-stage blowing and forced perforated plate mechanical dispersion powder distribution methods of the wetting powder preparation technology still have the following problems in use: 1. Because the new wetting powder preparation technology adopts a multi-stage blowing powder distribution method, and in order to ensure smooth powder drop from the perforated plate in the forced perforated plate mechanical dispersion powder distribution method, large-diameter (20mm) perforations must be used. This results in localized concentration of falling fine powder and insufficient uniform dispersion, requiring a powerful fan to provide air pressure and air volume, which increases the size of the system dust collector and the complexity and investment of the powder distribution structure. 2. Because the mixture of wind and powder has wind erosion properties, the perforated plate is easily damaged by wind erosion. 3. The ceramic fine powder itself has a high density, and the free fall state inside the tower is obvious, making it difficult to disperse by wind.

[0004] Therefore, finding a way to uniformly distribute fine powder in a wetting system without wind has become a key issue in improving and advancing the wetting powder production process. It is necessary to develop a high-frequency vibration powder distribution device for wetting powder production of building ceramics. Utility Model Content

[0005] The purpose of this invention is to provide a high-frequency vibration powder distribution device for wetting and powdering of building ceramics, which replaces the multi-stage blowing powder distribution and forced perforated plate mechanical dispersion powder distribution in the existing wetting and powdering technology by using a windless uniform powder distribution method.

[0006] To achieve the above objectives, this utility model provides a high-frequency vibration powder distribution device for wetting and powdering building ceramics, comprising a powder distribution ring frame, a vibration damping spring, and a fixing ring frame arranged sequentially from top to bottom. The two ends of the vibration damping spring are fixedly connected to the powder distribution ring frame and the fixing ring frame, respectively. A sealing cover, a primary powder distribution inverted cone, and a secondary powder distribution mesh plate are fixedly connected sequentially from top to bottom to the inner side wall of the powder distribution ring frame. A vibration source assembly is fixedly connected to the outer side wall of the powder distribution ring frame. A powder inlet is provided at the top of the sealing cover, and a powder outlet is provided at the bottom of the powder distribution ring frame.

[0007] Preferably, a plurality of tie rods are fixedly connected between the primary powder-distributing cone and the secondary powder-distributing mesh plate, and the two ends of the tie rods are fixedly connected to the primary powder-distributing cone and the secondary powder-distributing mesh plate, respectively.

[0008] Preferably, the vibration source assembly includes two high-frequency vibration motors symmetrically arranged on the outer side wall of the powder distribution ring frame.

[0009] Preferably, a powder inlet flexible connector retaining ring is fixedly connected to the powder inlet, and a powder outlet flexible connector retaining ring is fixedly connected to the powder outlet.

[0010] Therefore, the high-frequency vibration powder distribution device for wetting and powdering building ceramics with the above-mentioned structure has the following beneficial effects:

[0011] The device utilizes the vibration of the vibration source component to achieve uniform powder distribution without wind, while the vibration damping spring ensures that the powder distribution device meets the requirements for high-altitude support stability and safety. It replaces the combination of multi-stage blowing powder distribution and forced perforated plate mechanical dispersion powder distribution in the existing wet powder making technology. The equipment structure is simpler, the failure rate is lower, the operating cost and equipment cost are reduced, and the powder production output, quality and economic benefits are improved.

[0012] The initial uniform distribution of fine powder is achieved by using a primary powder distribution cone with inverted holes, and the uniformity of powder distribution is further improved by using a secondary powder distribution screen.

[0013] The use of tie rods increases the stability of the secondary powder-coating screen, preventing the central part of the screen from fluctuating violently due to resonance, thus avoiding frequent screen replacements.

[0014] The inlet and outlet flexible interface retaining rings facilitate closed operation of powder inlet and outlet, preventing dust generation.

[0015] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0019] 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.

[0020] 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. Example

[0021] Reference Figures 1-2 As shown, this embodiment provides a high-frequency vibration powder distribution device for wetting and powdering building ceramics, including a powder distribution ring frame 1, a vibration damping spring 2, and a fixing ring frame 3 arranged sequentially from top to bottom. The two ends of the vibration damping spring 2 are fixedly connected to the powder distribution ring frame 1 and the fixing ring frame 3, respectively. A vibration source assembly is fixedly connected to the outer wall of the powder distribution ring frame 1. A sealing cover 5, a primary powder distribution inverted cone 6, and a secondary powder distribution mesh plate 7 are fixedly connected sequentially from top to bottom to the inner wall of the powder distribution ring frame 1. The bottom end of the sealing cover 5 is fixedly connected to the top end of the inner wall of the powder distribution ring frame 1. The sealing cover 5, the primary powder distribution inverted cone 6, and the powder distribution ring frame 1 can be welded together. The secondary powder distribution mesh plate 7 and the powder distribution ring frame 1 can be welded together or connected by a clamp. The top end of the sealing cover 5 has a powder inlet, and the bottom end of the powder distribution ring frame 1 has a powder outlet.

[0022] In use, a primary powder distribution cone 6 with an aperture and spacing of approximately 20mm is used, along with a secondary powder distribution mesh plate 7 with an aperture and spacing of 2mm to 3mm. The powder distribution ring frame 1 and the fixing ring frame 3 are made of thick annular square steel, and the vibration damping spring 2 is a damping vibration damping spring. After the vibration source assembly is started, the powder distribution ring frame 1, the sealing cover 5, the primary powder distribution cone 6, and the secondary powder distribution mesh plate 7 vibrate. At this time, after the powder is introduced into the sealing cover 5 from the powder inlet, the powder will first fall on the primary powder distribution cone 6 and flow down along the cone surface, achieving a preliminary uniform distribution of fine powder. Then, it falls on the secondary powder distribution mesh plate 7, further improving the uniformity of powder distribution. Finally, it enters the wetting tower body through the powder outlet for wetting operations.

[0023] The aforementioned powder distribution 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 preparation, while also eliminating the need for a blower system. This simplifies the equipment structure used for powder distribution, reduces power consumption, and achieves more uniform powder distribution, thus ensuring the wetting effect and quality of wet powder preparation. Correspondingly, the dust collector configuration in the wet powder preparation system has been simplified, as have the constant pressure exhaust hood and airlock cone, resulting in a simpler wetting system structure, lower failure rate, reduced operating costs, and improved powder production output, quality, and economic efficiency.

[0024] In a further optimized scheme, several tie rods 8 are fixedly connected between the primary powder-distributing cone 6 and the secondary powder-distributing mesh plate 7, with the two ends of the tie rods 8 being fixedly connected to the primary powder-distributing cone 6 and the secondary powder-distributing mesh plate 7, respectively.

[0025] When in use, the number of tie rods 8 can be set to more than 5. The tie rods 8 are used to increase the stability of the secondary powder coating screen 7 and prevent the central part of the secondary powder coating screen 7 from fluctuating violently due to resonance, thereby avoiding frequent screen replacement.

[0026] In a further preferred embodiment, the vibration source assembly includes two high-frequency vibration motors 4 symmetrically arranged on the outer side wall of the powder distribution ring frame 1.

[0027] In use, the high-frequency vibration motor 4 can drive the powder distribution ring frame 1, the sealing cover 5, the first-stage powder distribution inverted cone 6 and the second-stage powder distribution mesh plate 7 to vibrate with high frequency and small amplitude, thereby achieving uniform powder distribution.

[0028] A further optimized solution is provided, wherein a powder inlet flexible interface retaining ring 9 is fixedly connected to the powder inlet, and a powder outlet flexible interface retaining ring 10 is fixedly connected to the powder outlet.

[0029] In use, the lengths of both the powder inlet flexible interface retaining ring 9 and the powder outlet flexible interface retaining ring 10 can be set to 100mm. The powder inlet flexible interface retaining ring 9 is used to lock the bag with a flexible connection, and the powder outlet flexible interface retaining ring 10 realizes the flexible connection between the bag and the wetting tower body, thereby ensuring that the well dispersed powder can fall directly into the cylinder body without dust.

[0030] Therefore, this utility model is a high-frequency vibration powder distribution device for wetting and powdering of building ceramics with the above-mentioned structure. It uses a windless uniform powder distribution method to replace the multi-stage blowing powder distribution and forced perforated plate mechanical dispersion powder distribution in the existing wetting and powdering technology.
