Description

Technical Field

[0001] The invention relates to the technical field of ceramic material preparation, and in particular to a ceramic micro-bead wet blank drying system and a drying method thereof. Background Art

[0002] Gelcasting is an important preparation method in the preparation of ceramic materials. It mixes ceramic powder and organic binder to form a slurry with high solid content, relatively low viscosity and good fluidity, and then forms a spherical wet blank with a certain shape and strength under the induction of initiator, catalyst and temperature. The wet blank obtained by this method often contains a lot of water, which needs to be removed by drying to ensure the smooth implementation of the next process.

[0003] The existing drying of the spherical wet blank obtained by injection molding is mainly carried out manually or semi-automatically, and the collected liquid containing the injected spherical wet blank is poured into the cleaning equipment, and then the cleaned spherical wet blank is transferred to the drying equipment manually or mechanically for drying. Although this method can achieve the cleaning and drying of the injected spherical wet blank, the cleaning and drying efficiency is low, and the wet blanks and wet blanks are easy to gather together and slide in a small area in the rotating cylinder during the drying process of the washed wet blank by the drying equipment, so that the sphericity of the dried blank obtained by drying is not good, which easily leads to deformation or cracking of the final product. Therefore, there is an urgent need for a drying system that can achieve continuous production and obtain a dry blank with good sphericity. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that there is a lack of a drying system that can realize continuous production of wet blanks obtained by injection molding and obtain dry blanks with good sphericity, thereby providing a ceramic microbead wet blank drying system and a drying method thereof.

The spherical wet billet is moved and rotates along the circumferential direction to a high position with the rotating drying cylinder. When the spherical wet billet is rotated and lifted to a higher position, it descends under the action of gravity generated by its own weight, so that the spherical wet billets gathered together are separated from each other, and a single spherical wet billet moves around its own axis inside the rotating drying cylinder, performing a motion similar to "rotation", so that a single spherical wet billet can perform a "revolution" motion while rotating with the rotating drying cylinder and a "rotation" motion at the same time, thereby ensuring that a dried billet with better sphericity and high surface finish is obtained, and further ensuring that the final product is not prone to problems such as deformation or cracking.

[0024] The cleaning component ultrasonically cleans the spherical wet blank and transports it to the drying mechanism;

[0025] The heating component is started and the rotary drying cylinder is started at the same time, so that the spherical wet blank is moved by the disturbance component during the rotation of the rotary drying cylinder and is dried by the heating component to form a dry blank.

[0026] A drying method according to the present invention has at least the following technical effects:

[0027] By sequentially connecting the separation component, the cleaning component and the drying mechanism along the conveying direction, after the liquid containing the spherical wet blank is obtained by gel injection molding, the operator only needs to convey the liquid containing the spherical wet blank to the separation component, the separation component separates the spherical wet blank from the liquid and automatically conveys it to the cleaning component for ultrasonic cleaning, and then the cleaning component automatically conveys the ultrasonically cleaned spherical wet blank to the drying mechanism for drying to obtain a dry blank, and the entire process realizes automated continuous production with high production efficiency; at the same time, by arranging a disturbance component inside the rotating drying cylinder, the disturbance component gathers the spherical wet blank in the process of rotating the rotating drying cylinder. The spherical wet billets gathered together are moved and rotated along the circumferential direction to a high position with the rotating drying cylinder. When the spherical wet billets are rotated and lifted to a higher position, they drop under the action of the gravity generated by their own weight, so that the spherical wet billets gathered together are separated from each other, and a single spherical wet billet moves around its own axis inside the rotating drying cylinder, performing a motion similar to "rotation", so that a single spherical wet billet can perform a "revolution" motion while rotating with the rotating drying cylinder and a "rotation" motion at the same time, thereby ensuring that the dried billets have better sphericity and high surface finish, and further ensuring that the final product is not prone to problems such as deformation or cracking.

[0046] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] Embodiment 1

[0048] like Figures 1 to 4 The present embodiment shows a ceramic micro-bead wet blank drying system, which includes a separation component, a cleaning component and a drying mechanism 1 arranged in sequence along the conveying direction. The drying mechanism 1 includes a rotary drying cylinder 11 and a heating component. The feed end of the rotary drying cylinder 11 is connected to the cleaning component, and is used for the spherical wet blank output by the cleaning component to pass through and enter the interior of the rotary drying cylinder 11. The interior of the rotary drying cylinder 11 is provided with a disturbance component, which is used to move the spherical wet blank during the rotation of the rotary drying cylinder 11. The heating component is used to heat the interior of the rotary drying cylinder 11. It can be understood that the conveying direction described in the text is Figure 1 The conveying direction is shown in .

[0049] The ceramic microbead wet blank drying system of the present embodiment is configured by sequentially connecting the separation component, the cleaning component and the drying mechanism 1 in the conveying direction. After the liquid containing the spherical wet blank is obtained by injection molding, the operator only needs to convey the liquid containing the spherical wet blank to the separation component. The separation component separates the spherical wet blank from the liquid and automatically conveys it to the cleaning component for cleaning. Then the cleaning component automatically conveys the cleaned spherical wet blank to the drying mechanism 1 for drying to obtain a dried blank. The whole process realizes automated continuous production with high production efficiency. At the same time, a disturbance component is arranged inside the rotary drying cylinder 11. The disturbance component is in the rotary drying cylinder 11. During the rotation of the cylinder 11, the spherical wet blanks gathered together are moved and rotated along the circumferential direction with the rotating drying cylinder 11 to a high position. When the spherical wet blanks are lifted to a higher position by rotation, they fall under the action of gravity generated by their own weight, so that the spherical wet blanks gathered together are separated from each other, and a single spherical wet blank moves around its own axis inside the rotating drying cylinder 11, performing a motion similar to "rotation", so that a single spherical wet blank can perform "revolution" motion while rotating with the rotating drying cylinder 11 in the rotating drying cylinder 11 and "rotation" motion at the same time, thereby ensuring that a dried blank with better sphericity and high surface finish (such as Figure 6 As shown), the final product is less likely to deform or crack.

[0050] It can be understood that after the spherical wet billets gathered together fall and impact the inner wall of the rotary drying cylinder 11 to separate from each other into independent single spherical wet billets, the disturbance component also moves the single spherical wet billets during the rotation of the rotary drying cylinder 11, and rotates them along the circumferential direction to a high position together with the rotary drying cylinder 11, and then falls under the action of its own weight to perform a movement similar to "rotation".

[0051] It should be noted that when the spherical wet blanks are rotated and lifted to a higher place, because the vertical projection of the spherical wet blanks does not fall within the range of the disturbance component, that is, there is no disturbance component to provide upward supporting force, the spherical wet blanks can fall under the action of the gravity generated by their own weight and impact the inner wall of the rotating drying cylinder 11, so that the spherical wet blanks gathered together are separated from each other.

[0052] It should be noted that the spherical wet blanks are spherical in shape, and there are attachments such as water or oil on the surface, which results in strong adsorption between the spherical wet blanks and very little friction with the inner wall of the rotary drying cylinder 11. Therefore, if no disturbance component is added inside the rotary drying cylinder 11, it is easy to cause most of the spherical wet blanks to gather together and slide in a very small area at the lower part of the rotary drying cylinder 11, and most of the spherical wet blanks do not rotate, so that the heat drying effect of different positions of the spherical wet blanks is different, that is, the spherical wet blanks are not uniformly heated and dried, resulting in unidirectional shrinkage during the drying process, thereby resulting in poor sphericity and low surface finish of the dried blanks (such as Figure 7 shown).

[0053] like Figures 2 to 4 As shown, specifically, the cross-sectional profile of the rotary drying cylinder 11 perpendicular to its axial direction is circular; the rotary drying cylinder 11 is inclined with respect to the horizontal plane, and more specifically, the inclination angle of the rotary drying cylinder 11 is set to 30°.

[0054] Specifically, the middle of the end surface of the rotary drying cylinder 11 which is axially away from the feeding end is connected to a rotary motor via a rotary shaft 14 ; the arrangement direction of the rotary shaft 14 is parallel to the axial direction of the rotary drying cylinder 11 .

[0055] like Figure 2 As shown, optionally, the disturbance assembly includes a plurality of disturbance brushes 12, preferably two disturbance brushes 12, which are arranged at intervals along the circumference of the rotary drying cylinder 11. The disturbance brushes 12 act like a "rake" to comb the spherical wet blanks gathered together and drive the spherical wet blanks to rotate along the circumference to a high position with the rotary drying cylinder 11. When the spherical wet blanks are lifted to a higher position, they will fall under the action of gravity generated by their own weight, so that the spherical wet blanks gathered together are better separated from each other, and a single spherical wet blank moves around its own axis inside the rotary drying cylinder 11, performing a motion similar to "rotation", so that a single spherical wet blank can perform a "revolution" motion while rotating with the rotary drying cylinder 11 in the rotary drying cylinder 11 and a "rotation" motion can be performed at the same time, thereby ensuring that the dried blanks have a better sphericity and a high surface finish, and further ensuring that the final product is not prone to deformation or cracking.

[0056] In specific applications, the number of disturbance brushes 12 can be reasonably increased or decreased according to the actual drying requirements of the spherical wet blanks. For example, in other embodiments, the number of disturbance brushes 12 is set to one, three, four, five or other numbers.

[0057] like Figure 2As shown, optionally, a mounting frame 13 is provided inside the rotary drying cylinder 11, and the mounting frame 13 rotates together with the rotary drying cylinder 11. The disturbance brush 12 is provided on the mounting frame 13, and the end surface of the disturbance brush 12 facing away from the mounting frame 13 is attached to the inner wall of the rotary drying cylinder 11. By rotating the disturbance brush 12 synchronously with the rotary drying cylinder 11, and the disturbance brush 12 is attached to the inner wall of the rotary drying cylinder 11, the spherical wet blanks gathered together can be better combed and all the spherical wet blanks located at the lower part of the rotary drying cylinder 11 can be driven to rotate along the circumferential direction to a high position together with the rotary drying cylinder 11, so that the spherical wet blanks gathered together can be better separated from each other, and a single spherical wet blank moves around its own axis inside the rotary drying cylinder 11, thereby ensuring that the dried blanks have a better sphericity and a high surface finish.

[0058] The above is only a preferred structure of the disturbance component. As other alternatives to the above technical solution, the disturbance component can be set as a disturbance table convexly arranged on the inner circumference of the rotary drying cylinder 11, the disturbance component can also be a plate-like structure with grooves or holes arranged inside the rotary drying cylinder 11, and the disturbance component can also be a mesh structure arranged inside the rotary drying cylinder 11. In actual use, the disturbance component can be fixed and not rotated, and the rotation direction of the disturbance component can also be set opposite to the rotation direction of the rotary drying cylinder 11.

[0059] Optionally, a hydrophobic and oleophobic layer is provided on the inner wall of the rotary drying cylinder 11. The hydrophobic and oleophobic layer can reduce the adhesion between the inner wall of the rotary drying cylinder 11 and the spherical wet blank, preventing the spherical wet blank from sticking to the inner wall of the rotary drying cylinder 11, ensuring that the spherical wet blank will fall under the gravity generated by its own weight when it is rotated and lifted to a higher place, and ensuring that the surface finish of the spherical wet blank is not easily adversely affected.

[0060] Optionally, the heating assembly includes a hot air blower, which is used to deliver hot air to the interior of the rotary drying cylinder 11. In the process of delivering the cleaned spherical wet blanks to the rotary drying cylinder 11 for drying, the hot air blower is started to deliver hot air to the interior of the rotary drying cylinder 11, so that the spherical wet blanks are evenly contacted with the hot air at all positions during the "revolution" and "rotation" movements in the rotary drying cylinder 11, so that the spherical wet blanks are evenly heated and dried, thereby ensuring that the dried blanks obtained by drying have better sphericity and high surface finish.

[0061] In specific applications, the hot air blower can be a temperature-controlled hot air blower or a constant temperature hot air blower; in other embodiments, the heating component can use existing mature heating equipment to heat the inside of the rotary drying cylinder 11 to dry the spherical wet blanks.

[0062] like Figure 1 and Figure 5 As shown, optionally, the cleaning component includes an ultrasonic cleaning tank 21 and a rotating cleaning cylinder 22, the rotating cleaning cylinder 22 is arranged to be inclined upward along the conveying direction, and one end of the rotating cleaning cylinder 22 facing the separation component is arranged in the ultrasonic cleaning tank 21, and the interior is connected to the ultrasonic cleaning tank 21; the inner wall of the rotating cleaning cylinder 22 is spirally arranged with a spiral baffle 23 along the length direction of the rotating cleaning cylinder 22, and the spiral baffle 23 and the inner wall of the rotating cleaning cylinder 22 form a spiral conveying channel 24. By gradually tilting the rotary cleaning cylinder 22 upward along the conveying direction, the lower inlet end of the rotary cleaning cylinder 22 is located in the ultrasonic cleaning tank 21, and the higher outlet end of the rotary cleaning cylinder 22 extends outside the ultrasonic cleaning tank 21. After the spherical wet blank separated from the liquid is conveyed to the rotary cleaning cylinder 22, the rotary cleaning cylinder 22 is started to rotate, so that the spherical wet blank is slowly conveyed from bottom to top along the spiral conveying channel 24. The spherical wet blank will be conveyed by the ultrasonic cleaning tank when the rotary cleaning cylinder 22 is in the part of the ultrasonic cleaning tank 21. The cleaning liquid 21 performs dynamic ultrasonic cleaning, effectively removing the powder or dust remaining on the surface of the spherical wet blank, so that the surface cleanliness of the dried blank obtained by drying is higher; and when the spherical wet blank is spirally transported by the rotating cleaning cylinder 22 extending to the part outside the ultrasonic cleaning tank 21, the cleaning liquid mixed in the spherical wet blank will fall back to the ultrasonic cleaning tank 21 along the inclined rotating cleaning cylinder 22 under the action of gravity, which can reduce the number of times the cleaning liquid is replenished, and reduce the water content of the spherical wet blank after cleaning, shortening the time for drying the spherical wet blank in the drying mechanism 1 to obtain a dry blank.

[0063] Specifically, an ultrasonic transducer is disposed at the bottom of the ultrasonic cleaning tank 21 to implement ultrasonic cleaning of the spherical wet blank in the ultrasonic cleaning tank 21 .

[0064] Optionally, the inclination angle of the rotating cleaning cylinder 22 is less than 30°, preferably 15° here, because the spherical wet blank is spherical in shape and is not easy to be transported from bottom to top, and the larger the inclination angle of the rotating cleaning cylinder 22, the faster the rotation speed of the rotating cleaning cylinder 22 must be to transport the spherical wet blank upward; so in this embodiment, the inclination angle of the rotating cleaning cylinder 22 is set to 15°. It has been measured that under this inclination angle, the rotating cleaning cylinder 22 only needs a lower rotation speed to drive the spherical wet blank to be transported from bottom to top, and ensure the ultrasonic cleaning time of the spherical wet blank in the ultrasonic cleaning tank 21.

[0065] In specific applications, the inclination angle of the rotating cleaning cylinder 22 can be reasonably increased or decreased according to the ultrasonic cleaning time of the spherical wet blank and the operating speed of the rotating cleaning cylinder 22. For example, in other embodiments, the inclination angle of the rotating cleaning cylinder 22 is set to 0.5°, 8° or 28°, etc.

[0066] Optionally, the cleaning assembly further comprises a plurality of columns disposed on the inner wall of the rotating cleaning cylinder 22, and the plurality of columns are spirally arranged at intervals in the spiral conveying channel 24. The columns serve to disperse the spherical wet blanks, prevent the spherical wet blanks from agglomerating with the spherical wet blanks, and ensure that a single spherical wet blank is fully ultrasonically cleaned.

[0067] like Figure 1 As shown, optionally, the separation component includes a screen 31 that is gradually tilted downward along the conveying direction, and one end of the screen 31 facing the cleaning component is connected to the cleaning component. By gradually tilting the screen 31 downward along the conveying direction, when the liquid containing the spherical wet blank is conveyed to the feed end of the screen 31 located at a higher position, the liquid will flow out through the sieve holes on the screen 31, so that the spherical wet blank is retained on the upper surface of the screen 31, and automatically rolls down from top to bottom along the conveying direction and is conveyed to the cleaning component for ultrasonic cleaning, with a high degree of automation.

[0068] Specifically, a liquid collecting tank 32 is provided at the lower end of the screen 31, and the liquid collecting tank 32 is used to collect the liquid after the spherical wet blanks are separated.

[0069] Specifically, the separation assembly includes a plurality of screens 31 stacked in sequence from top to bottom, and the apertures of the screen holes of the plurality of screens 31 gradually decrease from top to bottom, so as to automatically separate the spherical wet blanks from the liquid material and automatically classify them according to different particle sizes. More specifically, a cleaning assembly is connected to the discharge end of each screen 31, so as to automatically tilt and dry the spherical wet blanks of different particle sizes after classification to obtain corresponding dried blanks.

[0070] like Figure 1 As shown, optionally, a vibration conveyor 4 is provided between the cleaning component and the drying mechanism 1. The vibration conveyor 4 can automatically convey the spherical wet blanks that have been ultrasonically cleaned and output by the cleaning component to the rotary drying cylinder 11, and on the other hand, the spherical wet blanks can be conveyed by vibration, which can prevent the spherical wet blanks from agglomerating with each other and discharge the cleaning liquid mixed in the spherical wet blanks.

[0071] like Figure 1As shown, optionally, the ceramic microbead wet blank drying system also includes an automatic discharging component 5, the discharging end of the automatic discharging component 5 is connected to the feeding end of the screen 31 through the ball liquid conveying groove 51; the automatic discharging component 5 is used to store the liquid containing the spherical wet blank, and to convey the liquid containing the spherical wet blank to the separation component. The operator only needs to store the liquid containing the spherical wet blank in the automatic discharging component 5 in advance. During the drying process of the spherical wet blank, the automatic discharging component 5 automatically and continuously conveys the liquid containing the spherical wet blank to the separation component, and the separation component separates the spherical wet blank from the liquid and automatically conveys it to the cleaning component for cleaning. Then the cleaning component automatically conveys the cleaned spherical wet blank to the drying mechanism 1 for drying to obtain a dried blank. The whole process realizes automated continuous production with high production efficiency.

[0072] Specifically, the automatic discharging component 5 adopts existing mature automatic discharging equipment, which can output the liquid material containing the spherical wet blanks.

[0073] Embodiment 2

[0074] like Figures 1 to 5 A drying method provided in this embodiment is shown, which is applied to the ceramic green blank drying system described in the first embodiment. The drying method comprises the following steps:

[0075] The slurry containing the spherical wet blanks is transported to a separation component, and the separation component separates the spherical wet blanks from the slurry and transports them to a cleaning component;

[0076] The cleaning assembly performs ultrasonic cleaning on the spherical wet blank and transports it to the drying mechanism 1;

[0077] The heating component is started and the rotary drying cylinder 11 is started at the same time, so that the spherical wet blank is moved by the disturbance component during the rotation of the rotary drying cylinder 11 and is dried by the heating component to form a dry blank.

[0078] The drying method of this embodiment is to connect the separation component, the cleaning component and the drying mechanism 1 in sequence along the conveying direction. After the liquid containing the spherical wet blank is obtained by injection molding, the operator only needs to convey the liquid containing the spherical wet blank to the separation component. The separation component separates the spherical wet blank from the liquid and automatically conveys it to the cleaning component for ultrasonic cleaning. Then the cleaning component automatically conveys the ultrasonically cleaned spherical wet blank to the drying mechanism 1 for drying to obtain a dried blank. The whole process realizes automated continuous production with high production efficiency. At the same time, a disturbance component is arranged inside the rotating drying cylinder 11. The disturbance component disperses the spherical wet blanks gathered together during the rotation of the rotating drying cylinder 11. The spherical wet blanks are moved and rotated along the circumferential direction to a high position with the rotating drying cylinder 11. When the spherical wet blanks are rotated and lifted to a higher position, they fall down under the action of the gravity generated by their own weight and impact the inner wall of the rotating drying cylinder 11, so that the spherical wet blanks gathered together are separated from each other, and a single spherical wet blank moves around its own axis inside the rotating drying cylinder 11, performing a motion similar to "rotation", so that a single spherical wet blank can perform a "revolution" motion while rotating with the rotating drying cylinder 11 in the rotating drying cylinder 11 and a "rotation" motion at the same time, thereby ensuring that the dried blanks have better sphericity and high surface finish, and further ensuring that the final product is not prone to problems such as deformation or cracking.

[0079] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
