Description

Technical Field

[0001] This invention belongs to the technical field of wetting towers for building ceramics production, and particularly relates to a rectangular anti-sticking wetting tower for building ceramics wetting and powdering. Background Technology

[0002] Since its invention and application, the wet powder preparation process for architectural ceramics has fundamentally solved the problems of dry powder preparation, which is characterized by the formation of granular powder, while also addressing the high energy consumption, high pollution, and high emissions associated with traditional wet powder preparation. In the actual application of wet powder preparation technology, the wetting system is crucial. Our company has addressed identified problems, leading to the continuous emergence of new technologies and the ongoing iteration and upgrading of supporting wetting production equipment. For example, the process has evolved from three-stage wind-driven powder distribution to windless high-frequency vibration powder distribution and ultrasonic vibration powder distribution to solve the problem of powder distribution uniformity; and from single-spindle atomization of suspended umbrella-shaped fine water mist to uniform atomization with alternating long and short sections, resulting in increasingly better wet powder preparation production effects.

[0003] However, the aforementioned wetting and vibration-based powder distribution methods still have the following problems: wetting relies on a fan-shaped spray system, which inherently has uneven fan area and variations from small to large, still causing localized uneven distribution of the fine water mist; during vibration-based powder distribution, the powder still exhibits uneven distribution. These unevennesses lead to the powder agglomerating after wetting, forming large wet lumps.

[0004] In addition, during the wet powder production process, the drift of high-pressure fine water mist wets the tower wall, easily causing powder to stick to the wall and form large lumps. This requires periodic tapping to remove the wet lumps. Furthermore, nozzle blockage can produce water droplets, forming wet powder lumps.

[0005] The aforementioned large wet lumps and wet powders easily cause blockages in the cone-shaped part of the wetting tower, requiring production to be stopped once blocked. Therefore, there is an urgent need to find solutions to the problems of wall adhesion and blockage of the cone-shaped discharge port during the wetting powder production process. Furthermore, the optimized design and improvement of the existing wetting tower's high-frequency vibration powder distribution and fine water mist support rods are even more urgently needed to enable the rapid and widespread application of wetting powder production in the building ceramics industry.

[0015] Preferably, the anti-sticking cloth cylinder, the powder feeding cylinder, and the powder feeding frame are all cubical, the powder feeding cone is a quadrangular pyramid, the powder feeding cover is a quadrangular frustum, and the spray rods are evenly distributed in one horizontal row, two horizontal rows, or two mountain-shaped rows within the powder feeding cylinder.

[0016] Preferably, a support plate is fixedly connected to the bracket, and one end of the spray bar is detachably connected to the water supply pipe on the support plate via a hose.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Example

[0040] Reference Figures 1-10 As shown, this embodiment provides a rectangular anti-sticking wetting tower for building ceramics wetting and powder preparation, including a support 1. From top to bottom, a storage bin 2, a high-frequency vibrating powder distributor 3, a powder feeding cylinder 22, and an anti-sticking cloth cylinder 4 are fixedly connected on the support 1. The top and bottom ends of the high-frequency vibrating powder distributor 3 are flexibly connected to the storage bin 2 and the powder feeding cylinder 22, respectively. The high-frequency vibrating powder distributor 3 uses multi-stage powder dispersion to achieve uniform powder falling. The powder feeding cylinder 22 is provided with uniformly distributed spray rods 5. The spray rods 5 are connected to a water tank 7 through a water supply pipe 6. The bottom surface of the spray rods 5 is provided with several downward-facing nozzles 26. The nozzles 26 are uniformly distributed within the vertical projection of the anti-sticking cloth cylinder 4. In this embodiment, the spacing between adjacent nozzles 26 is 100-200mm.

[0041] During use, the powder in the storage bin 2 falls into the high-frequency vibrating powder distributor 3. The high-frequency vibrating powder distributor 3 improves the uniformity of powder distribution during the falling process. Subsequently, the powder falls evenly into the upper powder cylinder 22. Under the action of the nozzle 26 spraying fine water mist evenly, the falling dry powder is uniformly wetted. During this process, since the nozzle 26 sprays downward, it can avoid the nozzle 26 being blocked by powder to produce water droplets and thus wet lumps of powder. The evenly wetted powder continues to fall into the anti-sticking cloth cylinder 4. At this time, since the anti-sticking cloth cylinder 4 itself has anti-sticking properties, it can prevent the powder from sticking to the inner wall of the wetting tower and forming large wet lumps. In the above process, with the uniform distribution of powder, uniform spraying of fine water mist, and the four functions of the nozzle 26 not clogging and producing water droplets, and the anti-sticking cloth cylinder 4, the formation of large lumps after the powder is wetted can be effectively reduced. This can effectively reduce the probability of blockage at the outlet 20 of the wetting tower, making it easier for the wetted powder to be smoothly removed from the wetting tower and fall onto the feeding belt 21 for transport to the next process. When the wetted powder is discharged, the moisture content can be detected by the online moisture detector 19 to facilitate the determination of whether the powder is wetted properly.

[0042] In a further preferred embodiment, the high-frequency vibrating powder distributor 3 includes a powder distribution frame 31 and a base 32 arranged vertically. At least one powder inlet sealing cover 33 is fixedly connected to the top of the powder distribution frame 31. The powder inlet sealing cover 33 is used for a flexible connection with the bottom of the storage bin 2 to prevent powder from diffusing into the air. A high-frequency vibration source 34 is fixedly connected to the outer wall of the powder distribution frame 31. The high-frequency vibration source 34 can be a high-frequency vibration motor or a transducer connected to an ultrasonic generator. Powder distribution cones 35 and perforated powder distribution mesh plates 36 are fixedly connected to the inner wall of the powder distribution frame 31, arranged vertically. There is at least one powder distribution cone 35, and each cone corresponds to one powder inlet sealing cover 33. There is one perforated powder distribution mesh plate 36. A powder distribution cover 37 is fixedly connected to the top of each powder distribution cone 35. The top opening size of the powder distribution cover 37 is smaller than the bottom opening size. The outer wall of the powder-distributing cone 35 is provided with evenly distributed powder-distributing holes 38 and perforated V-shaped diffusion guide plates 39. The tip of the perforated V-shaped diffusion guide plate 39 is located above the tail end of the perforated V-shaped diffusion guide plate 39, and the tip position has a slit. The base 32 is fixedly connected to the bracket 1, and the base 32 can be welded to the bracket 1. At the same time, the bottom of the base 32 is fixedly connected to the bracket 28 on the bracket 1. The base 32 and the powder-distributing frame 31 are connected by a shock-absorbing spring 310, which can be a damping shock-absorbing spring 310.

[0043] In use, when the wetting tower is of normal size, there is one powder distribution cone 35. When the wetting tower is larger, the number of powder distribution cones 35 can be set to four. The top opening of the powder distribution cover 37 is about 40% of the diameter of the bottom opening. The bottom surface of the powder distribution cover 37 is located at one-third of the distance from the top to the bottom of the powder distribution cone 35. The powder distribution cover 37 can block the upper middle area of ​​the powder distribution cone 35 and at the same time perform the first dispersion of the powder falling on it. This causes the powder falling from the storage bin 2 to scatter downwards from the top and middle of the powder distribution cone 35, preventing the powder from falling completely through the powder distribution hole 38 when passing through the upper middle part of the powder distribution cone 35. This also prevents the powder from being poorly distributed due to no powder passing through the lower part of the powder distribution cone 35. To address the issue of uniformity, the powder distribution cone 35 has a cone surface slope of 50–60 degrees, and the diameter and spacing of the drilled holes on the slope are 8–12 mm. The powder distribution cone 35, through its shape and structure, achieves a second layer of powder dispersion. The perforated V-shaped diffuser plate 39 guides the powder, ensuring a more uniform distribution on the four sides of the powder distribution cone 35, thus achieving a third layer of powder dispersion. The perforated mesh plate 36 is the fourth layer of powder dispersion structure. With a mesh diameter and spacing of 2–3 mm, the perforated mesh plate 36 allows the powder to fall evenly into the wetting tower. This four-fold powder dispersion system—powder distribution cover 37, powder distribution cone 35, perforated V-shaped diffuser plate 39, and perforated mesh plate 36—ensures uniform powder distribution within the wetting tower, preventing the formation of large wet lumps after wetting and reducing the probability of clogging.

[0044] In a further optimized design, a grid support member 23 is fixedly connected to the inner wall of the powder distribution frame 31. The grid support member 23 includes a first prism plate 231 evenly distributed horizontally and a second prism plate 232 evenly distributed horizontally. The first prism plate 231 and the second prism plate 232 intersect and are welded to form the grid support member 23. Both ends of the first prism plate 231 and the second prism plate 232 are welded to the inner wall of the powder distribution frame 31, and the bottoms of the first prism plate 231 and the second prism plate 232 extend out of the powder distribution frame 31. The top surface of the grid support member 23 is welded to the connection point of the powder distribution perforated mesh plate 36, and the top surface of the powder distribution perforated mesh plate 36 is welded to the connection point of the powder distribution cone 35. In use, the grid support member 23 can increase the seismic resistance of the powder distribution perforated mesh plate 36 and the powder distribution cone 35.

[0045] In a further optimized design, a connecting rod 24 connects two adjacent powder-distributing cones 35, with the bottom edge of the powder-distributing cone 35 welded to the bottom edge of the side wall of the connecting rod 24. The connecting rod 24 increases the connection strength between two adjacent powder-distributing cones 35.

[0046] Furthermore, the powder inlet sealing cover 33 is provided with a first observation window 8, and a transparent acrylic plate is fixedly connected inside the first observation window 8.

[0047] When in use, the first observation window 8 makes it easy to observe the working status of the powder cone 35, and thus make it easy to determine whether maintenance is needed.

[0048] Furthermore, the powder inlet sealing cover 33 is connected to the bottom end of the storage bin 2 via the powder inlet flexible retaining ring 9, and the bottom end of the powder distribution frame 31 is connected to the top end of the powder outlet flexible retaining ring.

[0049] In use, the powder inlet flexible retaining ring 9 can extend into the bottom of the storage hopper 2 and slide to connect with the inner wall of the bottom of the storage hopper 2. The powder inlet flexible retaining ring 9 can also be fixedly and sealed to the bottom of the storage hopper 2, but the powder inlet flexible retaining ring 9 needs to be retractable. The powder outlet flexible retaining ring includes a peripheral retaining ring plate 10 and a bag cylinder 11. The top side of the peripheral retaining ring plate 10 is fixedly connected to the inner wall of the powder distribution frame 31, such as by welding. The other top side of the peripheral retaining ring plate 10 is fixedly connected to the grid support member 23, such as by welding. The top of the bag cylinder 11 is fixedly connected to the bottom of the peripheral retaining ring plate 10, and the bottom of the bag cylinder 11 is fixedly connected to the top of the powder feeding cylinder 22. The bag cylinder 11 can unfold and stack with the vibration of the high-frequency vibrating powder distributor 3.

[0050] Furthermore, the anti-sticking cloth cylinder 4, the powder loading cylinder 22, and the powder loading frame 31 are all cubical, the powder loading cone 35 is a quadrangular pyramid, and the powder loading cover 37 is a quadrangular frustum. The spray rods 5 are evenly distributed in one horizontal row, two horizontal rows, or two mountain-shaped rows within the powder loading cylinder 22.

[0051] When in use, the structure of the single-row spray bar 5 is relatively simple and the installation steps are simple. The double-row spray bar 5 shortens the length of the spray bar 5, making it convenient for maintenance and replacement.

[0052] In a further optimized design, a support plate 12 is fixedly connected to the bracket 1, and one end of the spray bar 5 is detachably connected to the water supply pipe 6 on the support plate 12 via a hose 17. A first working platform 13 with a railing and a second working table 25 are also fixedly connected to the bracket 1. The first working platform 13 is arranged adjacent to each other below the support plate 12, and the second working table 25 is arranged adjacent to each other below the high-frequency vibrating powder distributor 3.

[0053] In use, the support plate 12 can be positioned 500mm below the top of the upper powder cylinder 22. The support plate 12 is used to install and fix the spray bar 5. The hose 17 enables a detachable connection between the spray bar 5 and the water supply pipe 6, and also facilitates the disassembly of the spray bar. The first working platform 13 facilitates personnel standing, thereby facilitating the maintenance of the spray bar 5. The second working table 25 facilitates personnel to observe the uniformity of powder distribution. The second working table 25 can be welded to the bracket 1 and to the base 32 in the high-frequency vibrating powder distributor 3.

[0054] In a further optimized scheme, the storage bin 2 includes a bin body 201, a rotary feeder 202, and a square cone 203. The top surface of the bin body 201 is connected to the feeding assembly 14, and the bottom surface of the bin body 201 is provided with an outlet in the same number as the powder inlet sealing cover 33. Each outlet is fixedly connected to a rotary feeder 202, and the bottom surface of the rotary feeder 202 is fixedly connected to a square cone 203. The cross-sectional dimensions of the square cone 203 gradually decrease from top to bottom.

[0055] In use, the feeding component 14 feeds the powder from the ground to the hopper 201 at the top of the support 1. The rotary feeder 202 controls the feeding speed. The characteristics of the rotary feeder 202 itself cause the powder to be fed intermittently. The square cone 203 can concentrate the powder, thereby achieving continuous feeding, which is beneficial for the uniform distribution of powder by the subsequent high-frequency vibrating powder distributor 3.

[0056] Furthermore, the feeding assembly 14 includes a tilting elevator 141, the top of which is connected to the top of the storage bin 2, and the bottom of which is connected to an airflow channel 142, which is connected to a dust collector.

[0057] In use, the dry powder screened by the impurity removal system is directly conveyed to the tilting elevator 141 through the air trough 142. A dust collector is installed at the air trough 142 to collect the air blower from the empty trough. The tilting elevator 141 lifts the dry powder to the storage silo 2 at the top of the wetting tower.

[0058] Further optimization of the solution: the anti-stick fabric cylinder 4 is made of Teflon non-stick fabric. The anti-stick fabric cylinder 4 is fixed to the bracket 1 by strapping. The bottom of the anti-stick fabric cylinder 4 is provided with a discharge port 20 with a square pyramid structure. The four corners of the bottom of the discharge port 20 are fixedly connected to the four columns on the bracket 1 by tension ropes 15. The tension ropes 15 are connected to the adjustable tension rope device 16. The bottom of the discharge port 20 is sewn with a dustproof skirt 27.

[0059] In use, tie straps are sewn to the corners of the cubic anti-stick fabric cylinder 4 and the square pyramidal discharge port 20. Then, tension ropes 15 are used to diagonally pull the four columns on the support 1 at the four corners of the bottom of the discharge port 20. Finally, the adjustable tensioner 16 on the tension ropes 15 and the tie straps are used to achieve a fixed connection between the anti-stick fabric cylinder 4 and the support 1. The Teflon non-stick fabric effectively prevents powder from sticking to the walls inside the wetting tower.

[0060] In a further optimized design, a second observation window 18 is provided on the side wall of the powder cylinder 22, located below the spray bar 5.

[0061] When in use, the second observation window 18 makes it easy to observe the wetting situation inside the wetting tower.

[0062] Therefore, the present invention provides a rectangular anti-sticking wetting tower for building ceramics with the above-mentioned structure, which increases the uniformity of powder distribution and wetting, and solves the problems of sticking to the wall and clogging the outlet 20 of the wetting tower.
