[0002] In the porcelain production process, clay preparation is an indispensable key link, which is related to the uniformity, bonding strength and plasticity of the porcelain clay. The adobe that has been carefully prepared can show better durability and more delicate texture during the firing process. However, traditional clay preparation devices often use a single spiral rod for stirring and extrusion. This design has certain limitations in efficiency and quality.
[0003] Although a single spiral rod can stir the clay and expel some air to a certain extent, its stirring range and efficiency are limited, making it difficult to continuously and efficiently transport and mix the surrounding clay. At the same time, due to the lack of stirring strength and uniformity, the air inside the clay is often difficult to completely expel, requiring long-term extrusion and repeated operations. This not only affects production efficiency, but may also have a potential impact on the quality of porcelain.
[0004] Therefore, it is very necessary to invent a multi-stage clay kneading device for processing Longquan celadon. Utility Model Content

[0020] As attached Figure 1 To Attachment Figure 3 As shown:
[0021] The utility model provides a multi-stage mud kneading device for processing Longquan celadon, comprising a multi-stage composite mud kneading machine 1, a vacuum pump 2, a shock absorber 3, a machine base 4 and a driving motor 5. The vacuum pump 2 is fixedly installed on the multi-stage composite mud kneading machine 1, the multi-stage composite mud kneading machine 1 is installed on the machine base 4 through the shock absorber 3, the driving motor 5 is fixedly installed on the machine base 4, and the driving motor 5 is connected to the multi-stage composite mud kneading machine 1.
[0022] The multi-stage composite mud making machine 1 includes a casing 11, a vacuum tube 12, a feed port 13, a sealing cover plate 14, a mud making screw rod 15, a vibration plate 16 and a flexible coupling 17. The interior of the casing 11 is connected to the vacuum pump 2 through the vacuum tube 12, and the vacuum pump 2 is fixedly installed on the outside of the casing 11; the feed port 13 is fixedly installed on the casing 11, and the sealing cover plate 14 is hingedly installed on the feed port 13; two mud making screw rods 15 are rotatably installed inside the casing 11, and either end of the two mud making screw rods 15 rotates through the casing 11 and is fixedly connected to the vibration plate 16, and the vibration plate 16 is fixedly connected to the output end of the driving motor 5 through the flexible coupling 17. The multi-stage composite mud making machine 1 adds parallel screw rods on the basis of the traditional single screw rod to form a double screw rod working mechanism, which greatly improves the efficiency of mud material transportation and mixing, ensures the stirring strength and uniformity, and overcomes the limitations of traditional design. At the same time, high-frequency vibration and periodic positive and negative pressure mechanisms are introduced to further enhance mud mixing, eliminate bubbles and improve product quality.
[0023] Embodiment 1:
[0024] Specifically, a conical feed port 13 is fixedly installed above one end of the casing 11. The conical design facilitates the smooth entry of mud and reduces the possibility of blockage. A discharge port is installed at the other end of the casing 11 to facilitate the smooth discharge of the processed mud. The vacuum pump 2 is arranged on one side above the discharge port of the casing 11. The vacuum pump 2 is a rotary vacuum pump. The vacuum pump 2 forms periodic positive and negative pressures inside the casing 11 through the vacuum tube 12. The rotary vacuum pump can efficiently evacuate and exhaust the inside of the casing 11 through its unique rotation mechanism, thereby forming periodic positive and negative pressures inside the casing 11. This periodic change in positive and negative pressure has a significant impact on the treatment effect of the mud.
[0025] In the negative pressure stage: the rotary vacuum pump extracts the air inside the housing 11 through the vacuum pipe 12 to form a negative pressure environment. In this process, the excess air and moisture in the clay are effectively discharged, making the clay more compact and uniform. At the same time, the negative pressure environment also helps to further mix the particles in the clay and improve its uniformity.
[0026] In the positive pressure stage: the rotary vacuum pump injects gas into the casing 11 through the vacuum tube 12 to form a positive pressure environment. This stage mainly plays a role in compacting the mud. Through the positive pressure, the mud is more tightly combined and the internal gap is reduced.
[0027] Specifically, the two clay-kneading spiral rods 15 rotatably installed inside the housing 11 are arranged in parallel to ensure that the clay can be evenly and efficiently stirred inside the housing. The clay-kneading spiral rod 15 is composed of a main shaft and spiral blades, which can drive the clay to perform continuous spiral motion, thereby achieving the mixing and transportation of the clay. One end of the main shaft of the clay-kneading spiral rod 15 rotates to pass through the housing 11 and is fixedly connected to the external vibration disk 16. This connection method enables the vibration generated by the vibration disk 16 to be directly transmitted to the clay-kneading spiral rod 15, thereby driving the spiral rod to generate high-frequency vibration. This high-frequency vibration can not only promote the mixing and uniform distribution of the clay, but also help eliminate bubbles and excess water in the clay, thereby improving the quality of the clay.
[0028] Specifically, the vibration disk 16 is a fan-shaped eccentric disk, and the vibration disk 16 is located on one side below the feed port 13 and at one end of the housing 11. The vibration disk 16 can generate a stable and efficient vibration effect when in operation.
[0029] Specifically, the flexible coupling 17 is a belt coupling, which can effectively connect the output end of the drive motor 5 with the vibration disk 16 to ensure the stability and reliability of power transmission; the shock absorber 3 is a spring-type shock absorber seat, and the shock absorber 3 is composed of a base, a spring and a support rod. The base of the shock absorber 3 is elastically connected to the support rod through a spring, and the support rod is fixedly connected to the casing 11, and the base of the shock absorber 3 is fixedly installed on the base 4. This design can effectively reduce the vibration and noise during the operation of the equipment, ensure the stable operation of the equipment, and reduce the interference to the surrounding environment.
[0030] Embodiment 2:
[0031] First, the mud enters the interior of the casing 11 through the feed port 13 and is sealed by the sealing cover plate 14. The drive motor 5 is started, and the power is transmitted to the vibration disk 16 and the mud kneading screw rod 15 through the flexible coupling 17, so that the vibration disk 16 generates stable vibration. The vibration of the vibration disk 16 is transmitted to the mud kneading screw rod 15, and then while the mud kneading screw rod 15 rotates, the mud kneading screw rod 15 performs high-frequency vibration inside the casing 11. The two parallel mud kneading screw rods 15 work together to ensure that the mud is uniformly and efficiently stirred and mixed inside the casing. And the vibration helps the mixing and uniform distribution of the mud, and can eliminate bubbles and excess water in the mud. At the same time, during the mixing process of the mud, the vacuum pump 2 starts to work and is connected to the inside of the casing 11 through the vacuum tube 12. The rotary working mechanism of the vacuum pump 2 enables it to efficiently evacuate and exhaust the inside of the casing 11, thereby forming periodic positive and negative pressures inside the casing 11. In the negative pressure stage, the excess air and moisture in the clay are effectively discharged, making the clay more compact and uniform; in the positive pressure stage, the clay is further compacted and the internal voids are effectively reduced. This periodic change of positive and negative pressure not only helps to mix and compact the clay, but also further improves the quality of the clay. Through the alternating action of positive and negative pressure, the particles in the clay are more fully mixed, and bubbles and loose areas are effectively eliminated, thereby improving the appearance and performance of the product.
[0032] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
