Description

[0002] In the production and processing of electronic ceramic components (such as multilayer ceramic capacitors and alumina ceramic substrates), electronic ceramic spray dryers are the core equipment for converting ceramic slurry into dry powder. They mainly atomize mixed slurry into tiny droplets, and then dry the droplets at a specific temperature to finally obtain ultrafine powder that meets the requirements of subsequent molding and sintering.

[0003] However, existing electronic ceramic spray dryers still have many technical defects in actual operation. For example, the storage structure of some existing equipment lacks an effective stirring mechanism, which leads to component stratification problems such as ceramic powder settling and organic phase floating during the storage and transportation of the slurry. This results in uneven composition of the droplets formed by subsequent atomization, affecting the quality of the dried powder. In addition, some equipment relies on manual intervention or simple temperature switch control, which cannot accurately sense and adjust the temperature changes in the drying chamber in real time. This can easily lead to problems such as excessively high temperature causing carbonization of organic binders in the slurry, or excessively low temperature causing insufficient drying of droplets. Therefore, there is an urgent need for an electronic ceramic spray dryer that can solve the above defects, achieve stable slurry stirring, uniform droplet atomization, automatic and precise temperature control, and stable operation, so as to improve the processing quality and production efficiency of electronic ceramic powder and meet the needs of large-scale and high-precision production of electronic ceramic components.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Please see Figure 1-7 This utility model provides a technical solution: an electronic ceramic spray dryer, comprising: a drying chamber 1, the interior of which is a cavity for accommodating the drying process of electronic ceramic slurry, and a heating plate is provided inside the drying chamber 1 to heat the environment inside the cavity to provide the heat required for drying the electronic ceramic slurry; when the droplets formed after the electronic ceramic slurry is atomized enter the cavity of the drying chamber 1, the heating plate will be activated and release heat to heat the environment inside the cavity, so that the droplets can quickly evaporate moisture in a suitable temperature environment, thus completing the drying process; thereby achieving the function of providing a stable heat supply for drying electronic ceramic slurry, and thus greatly improving the efficiency of droplet drying and the quality stability of the dried powder.

[0033] Atomizing disc 2 is installed on top of drying chamber 1. Atomizing disc 2 has a cavity structure for receiving mixed slurry and high-pressure gas, and breaking the mixed slurry into tiny droplets by airflow shear force to achieve atomization treatment of the mixed slurry. Mixed slurry tank 3 continuously supplies mixed slurry to atomizing disc 2. At the same time, external high-pressure gas also enters the cavity structure of atomizing disc 2. Inside the cavity, the airflow formed by high-pressure gas comes into full contact with the mixed slurry. With the help of airflow shear force, the mixed slurry is broken into fine and uniform tiny droplets. These droplets then fall from the bottom of atomizing disc 2 into drying chamber 1. This achieves the effect of efficiently converting mixed slurry into tiny droplets, thereby greatly increasing the contact area between the mixed slurry and the drying environment and accelerating the drying speed.

[0034] The mixing slurry tank 3, installed on the atomizing disc 2, is a sealed storage structure used to store the electronic ceramic mixed slurry to be atomized and to continuously supply the mixed slurry to the atomizing disc 2. The operator first injects the electronic ceramic mixed slurry to be atomized into the mixing slurry tank 3. Due to its sealed structure, the slurry is protected from external contamination or moisture evaporation during storage. During equipment operation, the mixing slurry tank 3 continuously and stably supplies the stored mixed slurry to the cavity structure of the atomizing disc 2 according to its needs. This achieves stable storage and continuous supply of the mixed slurry, greatly improving the continuity and stability of the atomizing disc 2's operation and preventing the atomization effect from being affected by interruptions or instability in the slurry supply.

[0035] A pneumatic stirring assembly 4 is installed on the mixing slurry tank 3 to uniformly stir the mixed slurry within the tank 3, preventing component stratification. A pressure pump 5 delivers regulated and stable high-pressure air to the power input end of the pneumatic stirring assembly 4. The high-pressure air enters the pneumatic stirring assembly 4 and drives it to rotate, causing the stirring structure of the pneumatic stirring assembly 4 to rotate uniformly within the mixing slurry tank 3. This stirs the mixed slurry, ensuring thorough mixing of all components and preventing the settling of heavy components such as ceramic powder and the floating of organic phases. This prevents stratification of the mixed slurry components, greatly improving the uniformity of the components and ensuring the consistency of droplet composition after subsequent atomization treatment.

[0036] A pressure pump 5 is installed on one side of the drying chamber 1. The input end of the pressure pump 5 is connected to an external high-pressure air source, and the output end is connected to the power input end of the pneumatic stirring assembly 4. It is used to deliver external high-pressure air to the pneumatic stirring assembly 4 after pressure regulation, providing stable power for the stirring action of the pneumatic stirring assembly 4. When the equipment requires the pneumatic stirring assembly 4 to work, the pressure pump 5 starts, its input end draws high-pressure air from the external high-pressure air source, and then the pressure of the high-pressure air is adjusted by the internal pressure regulation structure to reach the pressure value suitable for the operation of the pneumatic stirring assembly 4. Then, the adjusted and stable high-pressure air is delivered to the power input end of the pneumatic stirring assembly 4 through the output end. This achieves the function of providing stable and suitable power for the pneumatic stirring assembly 4, thereby greatly improving the stability of the stirring speed of the pneumatic stirring assembly 4 and ensuring uniform stirring effect.

[0037] Temperature control component 6 is located on one side of the drying chamber 1. It is used to monitor the temperature inside the drying chamber 1 in real time and automatically stabilize the temperature inside the drying chamber 1 within the optimal temperature range suitable for drying electronic ceramic slurry. When the temperature inside the drying chamber 1 changes, the temperature control component 6 will sense this change in real time. When the temperature exceeds the optimal drying range, its internal structure will automatically activate the adjustment mechanism to reduce the heating power of the heating plate to reduce heat output. When the temperature is lower than the optimal drying range, it will automatically increase the heating power of the heating plate to increase heat output, thus always controlling the temperature inside the drying chamber 1 within a suitable range. This achieves the function of real-time monitoring and automatic adjustment of the temperature inside the drying chamber 1, thereby greatly improving the stability of the drying environment for electronic ceramic slurry and ensuring that the physical properties of the dried powder meet the requirements of subsequent processing.

[0038] Furthermore, the pneumatic stirring assembly 4 includes a pneumatic box 401 mounted on top of the mixing slurry tank 3. A drive disc 402 is rotatably mounted inside the pneumatic box 401. Multiple sets of drive blades 403 are fixedly connected to the outer surface of the drive disc 402. A drive shaft 404 is fixedly connected inside the drive disc 402. The other end of the drive shaft 404 extends into the mixing slurry tank 3 and is fixedly connected to a stirring shaft 405. A connecting pipe 406 is fixedly connected to the side of the pneumatic box 401 away from the pressure pump 5. The other end of the connecting pipe 406 is fixedly connected to the atomizing disc 2. The pressure pump 5 delivers high-pressure air. Upon entering the pneumatic chamber 401, the airflow impacts the drive blades 403, causing the drive disc 402 to rotate within the pneumatic chamber 401. As the drive disc 402 rotates, it simultaneously drives the drive shaft 404 to rotate. The drive shaft 404 then drives the stirring shaft 405, which extends into the mixing slurry tank 3, to rotate, thereby achieving the stirring of the slurry. At the same time, some high-pressure air can also enter the atomizing disc 2 through the connecting pipe 406 to assist in atomization. This achieves the efficient conversion of high-pressure air power into stirring power and assists in atomization, thus greatly improving the power transmission efficiency of the pneumatic stirring assembly 4 and the overall collaborative working effect of the equipment.

[0039] Furthermore, the temperature control assembly 6 includes a sliding rheostat 601 and a sealed box 602 installed on one side of the drying chamber 1. A temperature sensing tube 603 is fixedly connected to one side of the sealed box 602, and the other end of the temperature sensing tube 603 extends into the inner cavity of the drying chamber 1. A sealing plate 604 is slidably connected inside the sealed box 602. A push rod 605 is fixedly connected to one side of the sealing plate 604, and the other end of the push rod 605 extends to the outside of the sealed box 602 and is fixedly connected to a sliding plate 606. The sliding plate 606 is slidably connected to the sliding rheostat 601. When the temperature inside the drying chamber 1 changes, the temperature detection tube 603 senses the temperature and causes the internal gas to expand or contract, thereby pushing or pulling the sealing plate 604 inside the sealed chamber 602 to slide. The sealing plate 604 drives the push rod 605 to move, and the push rod 605 pushes the sliding plate 606 to slide on the sliding rheostat 601, changing the resistance value of the sliding rheostat 601 connected to the circuit. This achieves the function of automatically adjusting the resistance of the sliding rheostat 601 through temperature changes, thereby greatly improving the sensitivity and adjustment accuracy of the temperature control component 6 to temperature changes.

[0040] Furthermore, a return spring 607 is fitted on the outer surface of the push rod 605 located between the sealing plate 604 and the inner wall of the sealing box 602. When the temperature inside the drying chamber 1 decreases and the gas inside the temperature detection tube 603 and the sealing box 602 contracts, the return spring 607 releases its elastic potential energy, pushing the sealing plate 604 to slide back to its initial position. The sealing plate 604 then drives the push rod 605 and the sliding plate 606 back to their corresponding positions, restoring the resistance of the sliding rheostat 601 to the value appropriate for the temperature. This achieves the function of assisting the sealing plate 604 and the sliding plate 606 in resetting, thereby greatly improving the timeliness and accuracy of the temperature control component 6 adjustment and avoiding adjustment lag when the temperature is too low.

[0041] Furthermore, both the temperature detection tube 603 and the sealing box 602 are filled with inert gas, and the temperature detection tube 603 and the sealing box 602 are connected in a continuous manner. When the temperature inside the drying chamber 1 changes, the inert gas in the temperature detection tube 603 and the sealing box 602 will undergo synchronous volume changes due to thermal expansion and contraction, stably pushing the sealing plate 604 to slide. Moreover, the inert gas has stable chemical properties and will not react with the equipment components or affect the drying of the slurry. Thus, the inert gas is used to stably transmit temperature change signals and protect the equipment, thereby greatly improving the stability of the temperature control component 6 and the service life of the equipment.

[0042] Furthermore, the bottom of the atomizing disc 2 is fixedly connected with multiple sets of evenly arranged spray nozzles; the tiny droplets formed inside the atomizing disc 2 will be sprayed downwards through the multiple sets of evenly arranged spray nozzles at the bottom. The even distribution of the spray nozzles allows the droplets to be evenly dispersed in the cavity of the drying chamber 1, avoiding the accumulation of droplets in local areas; thus achieving the effect of evenly dispersing and falling droplets, thereby greatly improving the uniformity of contact between droplets and drying hot air, and ensuring the consistency of powder particle size after drying.

[0043] Furthermore, a controller 9 is fixedly connected to one side of the drying chamber 1. The controller 9, the sliding rheostat 601, and the heating plate are connected in series by wires to form a series circuit. When the resistance of the sliding rheostat 601 changes, the current in the series circuit changes accordingly. The controller 9 receives the current change signal and further precisely adjusts the heating power of the heating plate according to the preset program to ensure that the heat output of the heating plate matches the drying requirements. This achieves the effect of precisely adjusting the heating plate power, thereby greatly improving the accuracy of temperature control in the drying chamber 1 and ensuring the stability of the slurry drying process.

[0044] Furthermore, multiple sets of stirring blades are fixedly connected to both sides of the stirring shaft 405. When the stirring shaft 405 rotates, the multiple sets of stirring blades on both sides will rotate synchronously in the mixing slurry tank 3 to fully stir the mixing slurry at different positions, break the concentration gradient that may be formed inside the slurry, and fully integrate the ceramic powder with the organic phase. This achieves the effect of stirring the mixing slurry in all directions, thereby greatly improving the uniformity of the mixing of each component of the slurry and avoiding the impact of uneven local slurry composition on the subsequent atomization and drying effect.

[0045] Furthermore, a discharge port 7 is fixedly connected to one side of the drying chamber 1. After the droplets are dried in the drying chamber 1 to form qualified electronic ceramic powder, the powder is discharged from the discharge port 7 on one side of the drying chamber 1 under the action of gravity or driven by the auxiliary conveying structure of the equipment. The staff can collect the powder at the discharge port 7. This achieves the function of conveniently collecting the dried powder, thereby greatly improving the efficiency of powder collection and reducing the residue of powder in the equipment.

[0046] Furthermore, bases 8 are fixedly connected to the four corners of the bottom of the drying chamber 1. During the installation and operation of the equipment, the bases 8 at the four corners of the bottom of the drying chamber 1 are in contact with the ground, providing stable support for the entire equipment and preventing the equipment from shifting position or loosening parts due to vibration during operation. At the same time, the bases 8 can also reduce the direct friction between the equipment and the ground. Thus, the equipment is stabilized and supported, which greatly improves the stability and safety of the equipment operation and extends the service life of the equipment.

[0047] In the production of electronic ceramic components such as multilayer ceramic capacitors (MLCCs) and alumina ceramic substrates, it is necessary to dry the electronic ceramic slurry, which is a mixture of ceramic powder, organic binder, dispersant, and solvent, into a uniform ultrafine powder to meet the requirements of subsequent molding and sintering. Electronic ceramic spray dryers can efficiently complete this core processing step. Their working principle is as follows:

[0048] First, the electronic ceramic slurry to be processed is pre-stored in a slurry tank 3 with a sealed storage structure. Then, the pressure pump 5 is started, and a stable air pressure is delivered to the power input end of the pneumatic stirring assembly 4. When the air pressure enters the pneumatic box 401 of the pneumatic stirring assembly 4, it drives multiple sets of drive blades 403 to rotate, thereby driving the drive disk 402 to rotate synchronously with the internally fixed drive shaft 404, which in turn drives the stirring shaft 405 to rotate. When the stirring shaft 405 rotates, it drives multiple sets of stirring blades on both sides to stir the slurry at a uniform speed, thereby ensuring that the components of the slurry always remain in a uniform and stable state, and providing a raw material basis with consistent composition for subsequent atomization treatment.

[0049] Subsequently, the uniformly stirred slurry in the mixing slurry tank 3 is continuously conveyed to the atomizing disc 2 installed on the top of the drying chamber 1. The atomizing disc 2 receives the slurry and high-pressure gas simultaneously through its own cavity structure. With the help of airflow shearing force, the slurry is broken into tiny and uniform droplets. The droplet-shaped slurry can significantly increase the contact area with the drying environment, thereby effectively shortening the drying time and improving the drying uniformity. This avoids the problem of uneven powder particle size caused by slurry agglomeration in traditional drying methods. In addition, multiple sets of uniformly arranged spray nozzles are fixedly connected to the bottom of the atomizing disc 2, which can further ensure the uniformity of droplet distribution.

[0050] Once the droplets form, they fall directly into the cavity inside the drying chamber 1. At this time, the pre-installed heating plate inside the drying chamber 1 activates, providing the necessary heat for the droplet drying. Simultaneously, the temperature control component 6 installed on one side of the drying chamber 1 enters the working state. Since the temperature detection tube 603 of the temperature control component 6 extends into the inner cavity of the drying chamber 1, the inert gas inside it, along with the sealed box 602, can expand and contract with the temperature changes inside the drying chamber 1. When the temperature is higher than the optimal drying range, the expansion of the inert gas pushes the sealing plate 604 inside the sealed box 602 to move, causing the push rod 605 and the sliding plate 606 to slide along the sliding rheostat 601. The outer surface of the push rod 605, located between the sealing plate 604 and the inner wall of the sealed box 602, is fitted with a return spring 607. At this time, the sliding plate 606 will increase the sliding rheostat. Since the voltage remains constant, the current decreases when the resistor connected to the circuit 601 is constant. Furthermore, because a controller 9 is fixedly connected to one side of the drying chamber 1, and the controller 9, the sliding rheostat 601, and the heating plate are sequentially connected by wires to form a series circuit, this device can automatically adjust the heating plate power by changing the current in the series circuit, thus reducing the heating intensity. When the temperature is below the optimal range, the reset spring 607 pulls the sealing plate 604 to reset, and the sliding plate 606 returns to its corresponding position, thereby increasing the current and thus increasing the heating plate power. Ultimately, this achieves automatic and stable temperature control inside the drying chamber 1, preventing the organic binder in the slurry from carbonizing and decomposing due to excessively high temperatures, or the droplets from not drying sufficiently and forming wet powder due to excessively low temperatures. This ensures the physical properties of the dried electronic ceramic powder and its compatibility with subsequent processing.

[0051] After the droplets have dried and formed qualified powder in the drying chamber 1, they can be collected through the fixed discharge port 7 on one side of the drying chamber 1. The base 8, which is fixedly connected to the four corners of the bottom of the drying chamber 1, provides stable support for the equipment throughout the process, ensuring that the relative positions of each component remain fixed during operation, and further ensuring the stability of the processing and the quality of the powder product.
