Description

Technical Field

[0001] The present disclosure relates to the field of ceramic processing, and in particular to a mud-water separation device. Background Art

[0002] During the slip casting process, mud is injected into the mold to form the green body. After slip casting, the excess mud in the mold will be released. This released mud contains a mixture of ceramic mud waste and water. In addition, during the process of opening the mold and trimming the green body, a mixture of some waste and water may also be generated. These wastes can be referred to as ceramic mud waste in this field. In order to separate the mixture of these ceramic mud wastes and a large amount of water, a sedimentation tank is generally used to separate the ceramic mud waste and water. For the same batch of ceramic production, the composition of the raw materials is almost the same.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the concept, specific structure and technical effects of the present disclosure in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present disclosure, other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure. In addition, all the connection relationships mentioned in the text do not refer solely to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interactively without conflicting with each other.

[0022] During the slip injection molding process, mud is injected into the mold to form a green body. After the slip injection is completed, the excess mud in the mold will be discharged. The discharged mud is a mixture of ceramic mud waste and water. In addition, in the processes of opening the mold and trimming the green body, a mixture of ceramic mud waste and water may also be produced. In this field, these wastes are generally referred to as ceramic mud waste. In order to separate these wastes and a large amount of water, sedimentation tank 1 technology is usually used to achieve effective separation of ceramic mud waste and water. In the same batch of ceramic production, the raw material composition is basically the same. If these ceramic mud wastes can be recycled and reused in the same batch of ceramic production, the required reprocessing steps are less, thereby improving the utilization rate of ceramic mud waste. However, the sedimentation tank 1 needs to stand for a long time to separate the ceramic mud waste, which cannot meet the fast production rhythm, thereby affecting the reuse efficiency of ceramic mud waste.

[0023] like Figures 1 to 3 As shown, a mud-water separation device includes a sedimentation tank 1, a frame 2, a conveying pipe 3, a spiral 4 and a motor 5. The frame 2 is arranged beside the sedimentation tank 1, the spiral 4 is arranged in the conveying pipe 3, the spiral 4 and the conveying pipe 3 can rotate relative to each other, the conveying pipe 3 is fixed on the frame 2, the conveying pipe 3 is inclined, the lower end of the conveying pipe 3 is inserted into the sedimentation tank 1, the fixed part of the motor 5 is fixed on the frame 2 or the conveying pipe 3, the motor 5 drives the spiral 4 to rotate, the upper side surface of the lower end of the conveying pipe 3 is provided with a feed hole 36 connected to the conveying pipe 3, and the lower side surface of the upper end of the conveying pipe 3 is provided with a discharge hole 37 connected to the conveying pipe 3.

[0024] The mud-water separation device utilizes the principle of spiral 4 conveying and gravity separation. The sedimentation tank 1 is used to preliminarily separate the mixture of ceramic mud waste and water, wherein the heavier ceramic mud waste will be deposited at the bottom of the tank. The frame 2 is fixed to the side of the sedimentation tank 1 to support the entire separation device. The conveying pipe 3 is installed at an angle, with one end inserted into the bottom of the sedimentation tank 1 and the other end located at a higher position. The spiral 4 is installed in the conveying pipe 3 and can rotate relative to the conveying pipe 3. The motor 5 is fixed on the frame 2 or the conveying pipe 3, and by driving the spiral 4 to rotate, the ceramic mud waste at the bottom of the sedimentation tank 1 is conveyed. A feed hole 36 is provided on the upper side of the lower end of the conveying pipe 3 for introducing the ceramic mud waste in the sedimentation tank 1 into the conveying pipe 3; a discharge hole 37 is provided on the lower side of the upper end for discharging the separated ceramic mud waste.

[0025] Through the innovative arrangement of the spiral 4 and the conveying pipe 3, the device can effectively improve the separation efficiency of ceramic mud waste and shorten the standing time, thereby significantly improving the recycling rate of the waste. In addition, the process of rapid separation and recycling of waste helps to reduce the demand for new raw materials, thereby reducing production costs. In terms of environmental protection, this technology effectively promotes the recycling of ceramic mud waste, reduces waste emissions, and has a positive impact on the environment. In terms of product quality, since the separated waste can be directly used in the same batch production, it helps to maintain the stability of the raw material composition, thereby improving the overall quality of ceramic products.

[0026] In the sedimentation tank 1, the ceramic mud waste is discharged through the discharge hole 37. In order to achieve effective and unified collection of these ceramic mud wastes, in a specific embodiment, the mud-water separation device is further equipped with a first collecting box 6. This first collecting box 6 is placed below the discharge hole 37, and is mainly used to receive and recover the ceramic mud waste that falls from the discharge hole 37. Through this design, the ceramic mud waste can be processed in an orderly and centralized manner, avoiding the environmental problems caused by random scattering, and also providing convenience for subsequent processing and reuse. In addition, this orderly collection method helps to keep the working environment clean and orderly, and improves the overall work efficiency and environmental quality.

[0027] When the spiral 4 is rotating, it has the ability to push the mixture of ceramic mud waste and water upward along the conveying pipe 3. In order to improve the conveying efficiency of ceramic mud waste, usually, the gap between the thread of the spiral 4 and the conveying pipe 3 will be designed to be relatively small, thereby improving the conveying efficiency. And such a design will also drive the water to move toward the discharge port. However, if there is too much water mixed in the ceramic mud waste, this will require additional water separation steps in the subsequent processing process, thereby reducing the overall processing efficiency. In order to solve this problem, in a specific embodiment, the mud-water separation device also includes a drain pipe 8. Specifically, drainage holes are provided on the lower side of the conveying pipe 3, and these drainage holes are directly connected to the inside of the conveying pipe 3. In this way, the drain pipe 8 is connected to the drainage holes, thereby achieving effective water separation and improving the overall processing efficiency.

[0028] To ensure that as much water as possible can be drained from the delivery pipe 3, thereby reducing the total amount of water contained in the ceramic mud waste discharged from the discharge hole 37 of the delivery pipe 3, in one specific embodiment, multiple drainage holes are designed. These drainage holes are all arranged on the lower side of the delivery pipe 3 to more effectively drain water. To further ensure efficient drainage, multiple drainage pipes 8 are also provided, each corresponding to a drainage hole. Through this design, each drainage hole can drain water, thereby reducing the moisture content of the ceramic mud waste discharged from the discharge hole 37 of the delivery pipe 3. This design can effectively improve drainage efficiency.

[0029] During the processing of ceramic clay waste, although the chemical composition of these waste materials is essentially the same, there are differences in their physical properties, particularly in the coarseness and fineness of the particles. To effectively screen out the ceramic clay with a smaller mesh size, i.e., finer particles, one embodiment utilizes a conveying pipe 3 with primary screening holes 38. These primary screening holes 38 communicate with the interior of the conveying pipe 3 and are located on the underside of the conveying pipe 3. The primary screening holes 38 are arranged between the discharge hole 37 and the feed hole 36 to provide a preliminary screening of the ceramic clay during transportation. In this way, the finer ceramic clay particles can be effectively separated, thereby achieving efficient utilization and classified processing of the waste materials.

[0030] To significantly improve the efficiency of the screening process, in one specific embodiment, multiple primary screening holes 38 are designed. This increases the number of primary screening holes 38, allowing the screening process to process more material in a shorter time, thereby significantly improving overall screening efficiency. This ensures that material can pass through these primary screening holes 38 more quickly during the screening process, reducing waiting time and increasing productivity. Furthermore, the design of multiple primary screening holes 38 can also increase screening uniformity.

[0031] To effectively collect the ceramic slurry that falls through the primary screening holes 38, in one embodiment, the mud-water separation device is further equipped with a second collection box 7. This second collection box 7 is carefully designed and positioned below the primary screening holes 38. Its primary function is to receive and store the ceramic slurry that falls through the primary screening holes 38. This ensures that the ceramic slurry is effectively collected after the initial screening, avoiding waste and facilitating subsequent processing and utilization.

[0032] The conveying pipe 3 is designed to achieve efficient transportation of ceramic mud. To facilitate installation and maintenance, in a specific embodiment, the conveying pipe 3 includes a lower tube body 31, an upper baffle 33, a lower baffle 34, and a cover plate 32. The lower tube body 31 is fixedly mounted on the frame 2 to ensure the stability of the conveying pipe 3. The cover plate 32 is fixed to the top of the lower tube body 31, forming a channel between the cover plate 32 and the lower tube body 31. The function of this channel is to accommodate the spiral body 4, allowing it to rotate freely within it. The two ends of the spiral body 4 are respectively connected to the upper baffle 33 and the lower baffle 34, ensuring its stability and reliability in the channel. To reduce friction, the two ends of the spiral body 4 are connected to the upper baffle 33 and the lower baffle 34 via bearings 35, thereby achieving smooth rotational motion. This design not only improves conveying efficiency but also facilitates daily maintenance and overhaul. With this structure, the conveying pipe 3 can be installed and disassembled more conveniently, greatly improving work efficiency.

[0033] To further enhance ease of processing and assembly, in one embodiment, a feed hole 36 is intentionally provided between the cover plate 32 and the lower tube 31. This design allows a mixture of waste ceramic sludge and water to enter the channel formed between the lower tube 31 and the cover plate 32 through the feed hole 36 during assembly. Furthermore, a discharge hole 37 is also provided on the lower tube 31 to allow the ceramic sludge to flow out.

[0034] To ensure that the ceramic mud waste can be discharged smoothly from the discharge hole 37 and avoid being blocked by atmospheric pressure, the designer has intentionally left an air inlet 9 between the cover plate 32 and the lower tube 31. This air inlet 9 is carefully positioned above the discharge hole 37 so that air can enter during the discharge process, thereby balancing the internal and external pressures and ensuring that the discharge hole 37 is not blocked by atmospheric pressure. This design not only improves the discharge efficiency but also ensures a smooth and stable discharge process.

[0035] The above specifically describes the preferred embodiments of the present disclosure, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present disclosure, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
