[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0031] This embodiment describes a clay pressing device, which relates to the field of ceramic manufacturing technology. It uses negative pressure suction to extract and enrich the solvent squeezed out of the clay blank, thereby realizing the recycling and reuse of the solvent.

[0032] Please see Figures 1 to 6 The clay pressing device in this embodiment includes a static press 100, a pressing mold 200, and a suction component 300. The static press 100 can provide a constant pressure to compress the clay blank. The pressing mold 200 can form a relatively closed space to promote the compression and deformation of the clay. The suction component 300 can suction the inner cavity of the pressing mold 200 to form a negative pressure state, which provides power for the enrichment of clay solvent.

[0033] The static press 100 includes a liftable compression head 110, which can directly act on the clay to provide pressure for extruding the clay.

[0034] The pressing mold 200 includes a mold body 210. A pressing cavity 211, adapted to fit a compression head 110, is provided in the middle of the mold body 210. The top of the pressing cavity 211 is positioned opposite the opening of the compression head 110. The compression head 110 and the compression cavity form a relatively sealed space, which restricts the movement of the clay and shapes it. The compression head 110 can compress the clay located in the pressing cavity 211, eliminating air bubbles and other defects in the clay, reducing porosity or uneven structure in the finished ceramic product, thereby improving the strength and surface finish of the final product.

[0035] The suction assembly 300 includes a suction unit 310 and a filter plate 320. The filter plate 320 is installed at the bottom of the pressing mold 200. The function of the filter plate 320 is to support the clay and simultaneously separate air and solvents from the clay. The presence of the filter plate 320 effectively separates the pores and solvents in the clay from the clay body. The suction unit 310 is connected to the bottom of the mold body 210 and communicates with the pressing cavity 211. The suction unit 310 extracts the separated air and solvents through the suction port at the bottom of the mold, avoiding solvent waste and reducing air pollution.

[0036] It should also be noted that the suction unit 310 can create negative pressure in the compression chamber, promoting the release of air from the clay and further improving the internal quality of the clay.

[0037] In some embodiments, please refer to Figure 5 The filter press plate 320 includes a filter layer 321 and a skeleton layer 322 disposed on both sides of the filter layer 321. The edges of the two skeleton layers 322 are integrally connected, sandwiching the filter layer 321 between the two skeleton layers 322. The skeleton layer 322 can enhance the overall structural stability of the filter press plate 320 and prevent the filter layer 321 from deforming or breaking due to excessive pressure during use. By sandwiching the filter layer 321, the skeleton layer 322 provides strong support for the filter layer 321, so that the entire filter press plate 320 maintains a stable shape during isostatic pressing and can withstand the pressure generated when pressing the clay.

[0038] By encasing the filter layer 321 with the skeleton layer 322, the filter layer 321 can maintain its filtration performance during long-term use, reducing wear or damage caused by pressure. The filter layer 321 is not easily deformed by the solvent, gas, and clay particles squeezed out during the pressing process, thus maintaining its high-efficiency separation performance.

[0039] In practical implementation, the skeleton layer 322 is a steel wire skeleton layer 322, which has high structural strength and can improve the overall structural strength of the filter plate 320. The filter layer 321 is a fiber filter layer 321, which allows air-soluble liquids to pass through while preventing solid substances in the clay from passing through.

[0040] It should be noted that a skeleton partition is provided between the two skeleton layers 322. The two ends of the skeleton partition are fixedly connected to the skeleton layer 322 to form a frame structure, which further improves the structural strength of the filter press plate 320.

[0041] In some embodiments, please refer to Figure 5 The suction unit 310 includes a suction hood 311 and a suction pump 312. The suction hood 311 is fixedly connected to the bottom of the mold body 210 and is tightly connected to the bottom area of ​​the pressing cavity 211, ensuring that the suction hood 311 can tightly cover the bottom area of ​​the mold. The suction hood 311 is connected to the suction pump 312 through a pipe. During the isostatic pressing process of the clay, after the solvent and air in the clay are separated by the filter plate 320, the suction hood 311 can efficiently extract these gases and solvents from the clay, avoiding their accumulation in the mold and causing solvent waste or air pollution.

[0042] The suction pump 312 is connected to the suction hood 311 via a pipe, and can continuously provide negative pressure to quickly suck out the air and solvent inside the mold. The efficient suction function of the suction pump 312 ensures the rapid and thorough removal of solvent and air, thereby improving the density of the clay and preventing air and solvent from adversely affecting the quality of the clay during the molding process.

[0043] In some embodiments, please continue reading Figure 5 The suction hood 311 includes a hood body 311a and a support plate 311b. One end of the support plate 311b is fixedly connected to the hood body 311a, and the other end of the filter press plate 320 abuts against the support plate 311b. The support plate 311b connects the hood body 311a and the filter press plate 320, providing additional support force and preventing the hood body 311a and the filter press plate 320 from deforming or displacing due to pressure or external force during use, thereby improving the reliability of the overall system.

[0044] The support plate 311b has multiple through holes for connecting the cover 311a and the pressing cavity 211. These through holes effectively connect the cover 311a and the pressing cavity 211. The through holes allow air, solvent, and gas to flow rapidly inside and outside the cover 311a, making the suction process more efficient. During the clay pressing process, these through holes provide a clear path, ensuring that the suction unit 310 can smoothly extract the gas and solvent separated from the clay, thereby improving the extraction efficiency of air and solvent.

[0045] In some embodiments, please refer to Figure 5 The cover 311a has openings at both ends and gradually narrows from top to bottom to form a enrichment cavity. The enrichment cavity can effectively concentrate the gas and solvent discharged from the clay pressing cavity 211, allowing them to converge in this area and be easily sucked up. The enrichment cavity makes it easier for the solvent and gas to be collected by the suction system during the flow process, rather than diffused to other areas, thereby improving the suction efficiency.

[0046] The enrichment chamber allows the gas and solvent in the chamber to gradually concentrate in a smaller outlet area as they flow. This allows the suction system to perform negative pressure suction more efficiently. The negative pressure action can quickly and effectively remove the gas and solvent, reducing their residue in the clay and ensuring the density and quality of the clay.

[0047] In some embodiments, please refer to Figure 6 The suction assembly 300 also includes a separation unit 330, which is located between the housing 311a and the suction pump 312. The two ends of the separation unit 330 are connected to the housing 311a and the suction pump 312 respectively via pipes. The separation unit 330 effectively separates the clay solvent from the gas in the air, ensuring that the solvent is not drawn away with the airflow. Through this separation process, the solvent can be collected and recycled, thereby reducing solvent waste, improving resource utilization, and reducing environmental pollution. The recycled clay solvent can be reused, reducing the demand for new solvent, helping to reduce production and environmental costs, and further optimizing the system's economics.

[0048] Ceramic clay solvents often contain chemical components, which can pollute the environment if discharged directly without treatment. Separation unit 330 effectively avoids this situation, further improving the environmental performance of the equipment.

[0049] For further implementation methods, please refer to Figure 6 The separation unit 330 includes a filter element 331 for separating and enriching clay solvent. Both ends of the filter element 331 are connected to the suction pump 312 and the bottom of the housing 311a via pipes. The filter element 331 can effectively separate the clay solvent enriched in the air. Since clay solvent is often carried out with the air during the suction process, the filter element 331 can perform physical or chemical separation of these solvents, ensuring that the solvent is not discharged into the air with the airflow, achieving effective recovery. The precise separation of clay solvent by the filter element 331 significantly improves the solvent recovery rate. The separated solvent can be reused, avoiding resource waste, reducing solvent consumption, and minimizing environmental pollution.

[0050] In practical implementation, filter element 331 is specifically a filter cartridge containing a cylindrical filter screen. The filter screen is typically made of metal or synthetic materials and has a small pore size, separating the clay solvent and gas through physical means. The filter screen can be made of different materials, such as stainless steel or polyester, to adapt to different solvents and working environments.

[0051] In some embodiments, please refer to Figure 6 A clay pressing device also includes a discharge assembly 400, which includes an air compressor 410. The air compressor 410 is connected to the side of a housing 311a via a pipe. By providing high-pressure airflow, the air compressor 410 can effectively discharge clay from the pressing mold 200. Air enters the side of the housing 311a through the pipe, generating pressure and pushing the clay to be easily demolded from the mold.

[0052] Compared to traditional mechanical or manual operation, the air compressor 410 can quickly generate sufficient airflow pressure, thereby accelerating the demolding process of clay and reducing the time and labor costs required for manual demolding.

[0053] The air compressor 410 applies air pressure evenly, which helps the clay maintain its overall shape when demolding, avoiding deformation of the clay surface or shape due to uneven pressure or excessive squeezing.

[0054] Because the air pressure is relatively mild, the air compressor 410 will not exert too much impact on the clay, which helps to protect the surface quality of the finished clay product and ensure the fineness and integrity of the clay after molding.

[0055] It should be noted that a clay pressing device also includes a packaging box. The air compressor 410, filter 331 and suction pump 312 are all installed in the packaging box, which can effectively save space, make the equipment layout more compact and orderly, reduce the floor space required by the device and improve the overall efficiency of the equipment.

[0056] The enclosure provides a closed working environment, sealing components such as the air compressor 410, filter 331, and suction pump 312 together, reducing interference from the external environment on the equipment. Especially in high temperature, high humidity, or dusty environments, it can effectively prevent the entry of external substances and reduce the risk of equipment failure and damage.

[0057] The enclosure effectively isolates the operating noise of the air compressor 410 and the suction pump 312, reducing noise pollution to operators and the surrounding environment and improving the comfort of the working environment.

[0058] Workflow: First, the clay blank is loaded into the pressing cavity 211 of the mold body 210, and the suction pump 312 is started. Then, the static press 100 is started, and the compression head 110 moves relative to the pressing cavity 211 of the mold body 210, compressing the clay blank in the compression cavity. At the same time, the suction pump 312 uses a pipeline to create negative pressure suction through the suction hood 311, which can remove the solvent and air squeezed out from the clay blank. The filter element 331 can separate the solvent in the air and enrich and recover the solvent. Finally, the air compressor 410 blows air into the hood 311a, pushing out the clay blank.

[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the present utility model.
