Description

Technical Field

[0001] This invention relates to the field of ceramic production, and in particular to a raw material screening and impurity removal device for ceramic production. Background Technology

[0002] In the production of ceramic products, particle size control and impurity removal of raw materials are crucial preliminary steps to ensure the quality of the finished product. Ceramic raw materials are mostly powdery or clay containing a certain amount of moisture. Before entering the ball mill and forming process, they need to be sieved to remove coarse particles, clumps, and impurities, ensuring uniform clay fineness. Currently, vibrating screens or drum screens are commonly used for sieving ceramic raw materials, with screen surfaces typically made of woven metal mesh or perforated plates. For dry powder sieving, when the raw material contains fine powder and sticky components with a certain moisture content, the screen holes are easily filled with fine powder or clumps of clay, leading to a sharp decrease in the effective screening area and reduced screening efficiency. This necessitates frequent shutdowns for cleaning, severely impacting continuous production.

[0003] In the prior art, Chinese invention patent CN117380526A discloses a dry separation device for ceramic production materials. This prior art also addresses the clogging problem in ceramic material screening by using a "vibration + mechanical knocking" method to maintain the smooth flow of the screen surface. The knocking action is actively driven by an independent drive mechanism, and the knocking position, frequency and phase are fixed and orderly. It is difficult to form multi-directional and asynchronous turbulent impacts in different areas of the screen surface, and the ability to peel off local sticky mud cakes is limited. The knocking mechanism is an external point knocking, which is not effective in cleaning the stuck and adhered materials inside the screen holes. In addition, it requires an additional drive, has a complex structure and high energy consumption. Summary of the Invention

[0004] The purpose of this invention is to provide a raw material screening and impurity removal device for ceramic production in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A raw material screening and impurity removal device for ceramic production includes a vibration mechanism for collecting raw materials, an inner vibration plate for dispersing raw materials, an inner vibration plate for vibrating and filtering raw materials, and a filtering mechanism. The vibration mechanism has an inner vibration plate installed inside, and the filtering mechanism is evenly arrayed on the inner vibration plate. The bottom of the filtering mechanism is connected to a disordered swinging mechanism to improve the vibration disorder effect and prevent clogging. The bottom of the vibration mechanism has a vibration component installed, and the evenly distributed mechanism is installed above the inner vibration plate. The inner vibrating plate is a flat plate structure. The filtration mechanism includes a conical filter head, which is movably connected to the inner vibrating plate. The inner vibrating plate has a circular hole that matches the conical filter head. The lower end of the conical filter head is fixed by a bottom connecting strip. An inner fixing ring is provided on the inner side of the bottom connecting strip. The inner side of the inner fixing ring is engaged with the disordered swing mechanism.

[0006] Preferably, the disordered swing mechanism includes a collision cylinder, the collision cylinder is fixed to the inner vibration plate by a tripod, a swing rod is slidably connected to the inner side of the collision cylinder, an impact block is installed at the top of the swing rod, a hammer ball is fixed to the bottom of the swing rod, an assembly cylinder is fixed to the outer side of the hammer ball, and the inner fixing ring is snapped to the outside of the assembly cylinder by a snap-fit ​​mechanism.

[0007] Preferably, the conical filter head is composed of multiple wedge-shaped wire screen plates, and the inner side of the conical filter head is formed with a cavity that matches the impact block, and the impact block has a drum-shaped structure.

[0008] Preferably, the diameter of the swing rod is half the inner diameter of the collision cylinder, and the swing rod swings inside the collision cylinder.

[0009] Preferably, the snap-fit ​​mechanism includes an elastic buckle plate and a buckle groove. The elastic buckle plate is formed on the outer wall of the assembly cylinder, and the buckle groove is formed on the inner wall of the inner fixing ring. The elastic buckle plate is a hemispherical spring sheet.

[0010] Preferably, the uniform distribution mechanism includes a dividing plate, and the dividing plate is provided with a plurality of transverse arrays installed inside the sealing cover of the oscillation mechanism, and dividing slots are formed between the dividing plates.

[0011] Preferably, the height of the dividing plate corresponding to the feed hopper of the oscillation mechanism gradually decreases towards the side away from the feed hopper, and the gap of the dividing slot gradually increases.

[0012] Compared with existing technologies, the beneficial effects are as follows: The raw materials are evenly distributed upon entry by the uniform distribution mechanism. The vibration component drives the vibration seat, inner vibration plate, and filtration mechanism to vibrate as a whole. The wedge-shaped wire screen structure of the conical filter head filters the powder raw materials. During the filtration process, the gaps and the vibration of the conical filter head itself prevent clogging. At the same time, the disordered swing mechanism at the lower end causes the impact block, swing rod, and hammer ball to form irregular impacts, increasing the degree of vibration disorder. This ensures low-frequency multi-angle vibration while avoiding adhesion problems caused by vibration and wet materials. Attached Figure Description

[0016] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0017] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-9 As shown, a raw material screening and impurity removal device for ceramic production includes a vibration mechanism 1 for collecting raw materials, an inner vibration plate 2 for dispersing raw materials, an inner vibration plate 2 for vibrating and filtering raw materials, and a filtering mechanism 4. The vibration mechanism 1 is equipped with an inner vibration plate 2, and the filtering mechanism 4 is evenly arrayed on the inner vibration plate 2. The bottom of the filtering mechanism 4 is connected to a disordered swinging mechanism 5 to improve the vibration disorder effect and prevent clogging. The bottom of the vibration mechanism 1 is equipped with a vibration component 6, and the even distribution mechanism 3 is installed above the inner vibration plate 2. The inner vibrating plate 2 is a flat plate structure. The filter mechanism 4 includes a conical filter head 41, which is movably connected to the inner vibrating plate 2. The inner vibrating plate 2 has a round hole formed to match the conical filter head 41. The lower end of the conical filter head 41 is fixed by a bottom connecting strip 42. An inner fixing ring 43 is provided on the inner side of the bottom connecting strip 42. The inner side of the inner fixing ring 43 is engaged with the disordered swing mechanism 5.

[0018] In this embodiment, the disordered swing mechanism 5 includes a collision cylinder 52, which is fixed to an inner vibrating plate 2 via a tripod. A swing rod 51 is slidably connected to the inner side of the collision cylinder 52. An impact block 56 is installed on the top of the swing rod 51. A hammer ball 53 is fixed to the bottom of the swing rod 51. An assembly cylinder 54 is fixed to the outer side of the hammer ball 53. An inner fixing ring 43 is snapped into the outside of the assembly cylinder 54 via a snap-fit ​​mechanism 55.

[0019] With this configuration, when the oscillating component 6 excites the inner oscillating plate 2 to vibrate, the hammer ball 53 is driven by inertia to swing the swing rod 51 in the collision cylinder 52 in a disorderly manner, and the impact block 56 intermittently hits the inner wall of the conical filter head 41, forming a multi-directional, asynchronous impact, which destroys the bridging and adhesion of powder in the gap of the wedge-shaped wire screen plate, thereby improving the anti-clogging effect and enhancing the material dispersion.

[0020] In this embodiment, the conical filter head 41 is composed of multiple wedge-shaped wire screen plates, and the inner side of the conical filter head 41 is formed with a cavity that matches the impact block 56. The impact block 56 has a drum-shaped structure.

[0021] With this configuration, multiple wedge-shaped wire screen plates surround a conical filter head 41, forming a continuous filter gap on the three-dimensional conical surface. The powder slides down the conical surface while being screened. The drum-shaped impact block 56 matches the arc-shaped contour of the inner cavity of the conical filter head 41, ensuring uniform contact and stress dispersion during impact. This effectively shakes off the adhering material while avoiding local deformation or damage.

[0022] In this embodiment, the diameter of the swing rod 51 is half the inner diameter of the collision cylinder 52, and the swing rod 51 swings inside the collision cylinder 52.

[0023] With this configuration, sufficient radial clearance is maintained between the swing rod 51 and the impact cylinder 52, allowing the swing rod 51 to swing freely at a large angle along the inner wall of the impact cylinder 52 under vibration excitation without jamming; this ratio takes into account both swing amplitude and structural stability, ensuring continuous and reliable random impact.

[0024] In this embodiment, the snap-fit ​​mechanism 55 includes an elastic buckle plate 551 and a buckle groove 552. The elastic buckle plate 551 is formed on the outer wall of the assembly cylinder 54, and the buckle groove 552 is formed on the inner wall of the inner fixing ring 43. The elastic buckle plate 551 is a hemispherical spring.

[0025] With this configuration, the assembly cylinder 54 can be quickly engaged with the buckle groove 552 on the inner fixing ring 43 via the hemispherical elastic buckle plate 551, thus achieving a detachable connection between the disordered swing mechanism 5 and the filter mechanism 4. During installation and maintenance, the entire assembly can be disassembled without tools, and the flexible fit after engagement allows for slight relative vibration between the two, further enhancing the anti-clogging effect.

[0026] In this embodiment, the uniform distribution mechanism 3 includes a dividing plate 31. The dividing plate 31 is provided with a plurality of transverse arrays installed inside the sealing cover 14 of the oscillation mechanism 1. Dividing slots 32 are formed between the dividing plates 31.

[0027] With this configuration, the material fed into the hopper 15 is first divided into multiple streams by several dividing plates 31 and their dividing slots 32, and then falls onto the array of conical filter heads 41 below; this avoids material accumulation in local areas, balances the load on each filter mechanism 4, and improves the overall screening efficiency and equipment utilization.

[0028] In this embodiment, the height of the dividing plate 31 corresponding to the feed hopper 15 of the oscillation mechanism 1 gradually decreases towards the side away from the feed hopper 15, and the gap of the dividing slot 32 gradually increases.

[0029] With this configuration, the height of the dividing plate 31 gradually decreases from the side of the feed hopper 15 to the far end, allowing the material flow to naturally diffuse to lower areas under the action of gravity and vibration; at the same time, the dividing slot holes 32 gradually increase in size from near to far, so that the flow rate of the material far from the feed end increases accordingly, compensating for the attenuation of the kinetic energy of the material at the far end, and achieving uniform material distribution across the entire plate surface.

[0030] Working principle: During operation, powdered ceramic raw materials are fed into the feed hopper 15 and are first divided into multiple streams by several dividing plates 31 and the dividing slots 32 between them by the equalization mechanism 3, and then evenly distributed across the entire plate surface. The vibration component 6 generates excitation force, which is transmitted to the entire vibration mechanism 1 through the vibration seat 11 and the column 13 in sequence, causing the inner vibration plate 2 and the filter mechanism 4 arrayed on it to vibrate as a whole. The vibration damping seat 12 absorbs and isolates the transmission of vibration to the outside, and the sealing cover 14 prevents dust from overflowing. The raw material is screened at the conical filter head 41 on the inner vibrating plate 2. The conical filter head 41 is composed of multiple wedge-shaped wire screen plates. The powder slides down the conical surface and passes through the screen, while coarse particles and impurities are intercepted. At the same time, the disordered oscillation mechanism 5 vibrates with the inner vibrating plate 2. The collision cylinder 52 is fixed to the inner vibrating plate 2 by a tripod. The swing rod 51 inside it drives the hammer ball 53 to swing disorderly under the action of inertia and radial clearance, so that the drum-shaped impact block 56 at the top intermittently hits the cavity inside the conical filter head 41, forming a multi-directional, asynchronous impact, which, in conjunction with the wedge-shaped wire screen... The natural self-cleaning properties of the plate gaps continuously disrupt the bridging, adhesion, and wet material agglomeration of powder at the gaps, thereby achieving anti-clogging and efficient screening without stopping the machine or adding water. The disordered swing mechanism 5 is flexibly engaged with the bottom of the filter mechanism 4 through the elastic buckle 551 of the snap-fit ​​mechanism 55 and the buckle groove 552 on the inner fixed ring 43, which facilitates overall disassembly and maintenance. The qualified powder under screening is discharged from the lower end of the conical filter head 41, and the coarse material that has not passed through screening is removed from the discharge port by vibration. The impurities at the top and the screened raw materials at the bottom flow out from the two discharge ports for collection.
