Description

Technical Field

[0001] This utility model relates to the field of ceramic clay cleaning technology, and specifically discloses a multi-stage cleaning device for ceramic clay. Background Technology

[0002] Porcelain clay is the main raw material for ceramics. It is named after the kaolin found near Jingdezhen, China, the world's first ceramic kiln. Pure porcelain clay is a white or grayish-white, soft mineral with a silky luster. Porcelain clay washing equipment, also known as a clay washing machine or washing equipment, is a mechanical device specifically used to purify, remove impurities, and classify raw porcelain clay (kaolin). It is a crucial pre-treatment step in the preparation of ceramic raw materials. In ceramic production, the washing of porcelain clay (kaolin, bentonite, etc.) is a vital process. Its purpose is to remove impurities such as quartz, mica, and iron from the porcelain clay, improving its purity and whiteness, thereby ensuring the quality of the final ceramic product.

[0003] Currently, common methods for cleaning kaolin clay mostly involve single-pool soaking or simple agitation. These methods have significant drawbacks: 1. Incomplete cleaning: A single cleaning can only remove some surface impurities, and it is ineffective at removing stubborn impurities that are deeply embedded.

[0004] 2. Low efficiency: Cleaning, sedimentation, and slag removal are all carried out in the same container, resulting in a long cycle and high water consumption. Utility Model Content

[0005] This invention proposes a multi-stage cleaning device for ceramic clay. Through two-stage cleaning processes of coarse washing and fine washing, the clay is gradually purified from coarse to fine, and the impurity removal rate is much higher than that of single-stage cleaning. Utilizing the overflow principle, the slurry can automatically flow from the previous stage to the next stage, realizing a continuous cleaning process and greatly improving production efficiency. Through the set-up circulating water system, the settled clean water is reused in the cleaning process, which greatly reduces the consumption of fresh water and the amount of wastewater discharged.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0018] Please see Figure 1-4 A multi-stage cleaning device for ceramic clay includes an outer shell 1. Multiple partitions 2 are fixedly connected inside the outer shell 1 and are distributed on the left and right. The multiple partitions 2 divide the outer shell 1 into a coarse washing tank 3, a fine washing tank 4, a sedimentation tank 5 and a water storage tank distributed from left to right. The outer walls of the multiple partitions 2 are all provided with overflow ports 7 of equal height. Both the coarse washing tank 3 and the fine washing tank 4 are equipped with a stirring mechanism and a waste removal mechanism. The stirring mechanism can stir the porcelain clay, and the waste removal mechanism can remove the impurities inside the coarse washing tank 3 and the fine washing tank 4. The sedimentation tank 5 is equipped with an inclined tube packing group 8, and the lower end face of the sedimentation tank 5 is connected to a sludge discharge pipe 9. A valve is installed on the outer wall of the sludge discharge pipe 9. A water pump 10 is installed inside the water storage tank 6. The outlet of the water pump 10 is connected to a return pipe 11, and the other end of the return pipe 11 is connected to the coarse washing tank 3.

[0019] In this embodiment: the porcelain clay raw material and water are put into the coarse washing tank 3, and then stirred at a low to medium speed by a stirring mechanism. The main function of this stirring mechanism is to loosen the porcelain clay lumps and, by utilizing the density difference between impurities and porcelain clay, to allow heavy impurities such as quartz and iron filings to quickly settle to the bottom slope of the coarse washing tank 3. Simultaneously, light floating soil in the slurry is stirred and separated. The slurry, after coarse washing, automatically overflows through the overflow port 7 into the fine washing tank 4. The stirring mechanism in the fine washing tank 4 operates at a higher speed to deeply emulsify and scrub the slurry, further removing light and fine impurities such as fine mica and organic matter attached to the surface of the porcelain clay particles. During the process, the remaining medium-density impurities, such as fine sand, also settle. This step-by-step overflow from left to right achieves continuous cleaning, and each tank focuses on treating impurities of a specific particle size, resulting in highly targeted cleaning and significantly higher efficiency than single-stage cleaning. In the coarse washing tank 3 and fine washing tank 4, the impurities separated by agitation settle under their own gravity. Thanks to the inclined structure of the tank bottom sloping towards the feed inlet 17, the settled impurities are naturally guided and collected in the impurity removal mechanism, and then discharged through it. This process can be carried out simultaneously during the cleaning operation, achieving continuous separation of impurities. The discharge ensures uninterrupted operation of the main cleaning process, greatly improving overall efficiency. The purified porcelain clay slurry, after fine washing, overflows into sedimentation tank 5. The inclined tube packing group 8 provides a large settling area (the inclined tube packing group 8 consists of a honeycomb module made of multiple slender hexagonal hollow tubes tightly bound together; this is a well-known and mature existing technology, and will not be described in detail here). Based on the "shallow sedimentation principle," this greatly accelerates the settling speed of the porcelain clay particles, enabling rapid separation of mud and water. The clarified water enters the storage tank 6 through overflow outlet 7, while the settled porcelain clay in sedimentation tank 5... The conical structure at the bottom further concentrates the mud into a high-density slurry. When the slurry needs to be used, the valve on the slurry discharge pipe 9 is opened, and the concentrated slurry is discharged under static pressure for subsequent production. The discharge time of the concentrated slurry is determined according to the amount of sediment to prevent the discharge time from being too long, which would cause the clarified water to be discharged along with the slurry. The clarified water collected in the water storage tank 6 is pumped back to the coarse washing tank 3 by the water pump 10 through the return pipe 11 as cleaning water. This constitutes a closed water circulation system, which greatly reduces the consumption of fresh water and the discharge of industrial wastewater, and achieves energy-saving and environmentally friendly production.

[0020] As a technical optimization of this utility model, the stirring mechanism includes a mounting plate 12 that is fixedly connected to the upper end of the coarse washing tank 3 and the fine washing tank 4 respectively. A rotating shaft 13 is rotatably connected to the lower end face of the mounting plate 12. A plurality of evenly distributed stirring rods 14 are fixedly connected to the outer wall of the rotating shaft 13. The rotating shaft 13 is driven by a first drive motor 15 installed on the upper end face of the mounting plate 12.

[0021] In this embodiment: the first drive motor 15 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives multiple stirring rods 14 to rotate, thereby stirring the porcelain clay raw material.

[0022] As a technical optimization of this utility model, the impurity removal mechanism includes a conveying cylinder 16 that is fixedly connected to the lower end of the coarse washing tank 3 and the fine washing tank 4 respectively. The lower end of the outer wall of the conveying cylinder 16 is provided with a feed inlet 17. The upper end of the conveying cylinder 16 extends to the top of the mounting plate 12. The upper end of the outer wall of the conveying cylinder 16 is connected to an impurity removal groove 18. The other end of the impurity removal groove 18 extends to the outside of the outer shell 1. The inside of the conveying cylinder 16 is rotatably connected to a spiral conveying blade 19. The spiral conveying blade 19 is configured as a mesh structure. The spiral conveying blade 19 is driven by a second drive motor 20 installed on the upper end face of the conveying cylinder 16.

[0023] In this embodiment: the second drive motor 20 drives the spiral conveyor blade 19 to rotate, and the spiral conveyor blade 19 transports the impurities that enter the conveying cylinder 16 through the feed inlet 17 to the impurity discharge trough 18, and then discharges them through the impurity discharge trough 18, thereby cleaning the impurities in the coarse washing tank 3 and the fine washing tank 4. Since the spiral conveyor blade 19 is set as a mesh structure, when transporting impurities, water will pass through the spiral conveyor blade 19 and will not be discharged through the conveying cylinder 16.

[0024] As a technical optimization of this utility model, the outer wall of the outer shell 1 is provided with an observation port 21 that communicates with the sedimentation tank 5, and the interior of the observation port 21 is fixedly and sealed with tempered glass.

[0025] In this embodiment: the observation port 21 facilitates the observation of the sedimentation amount of the concentrated mud. The tempered glass can seal the observation port 21 while allowing the concentrated mud to be observed.

[0026] As a technical optimization of this utility model, the lower interior of both the coarse washing tank 3 and the fine washing tank 4 is configured as an inclined surface structure that slopes towards the feed inlet 17.

[0027] In this embodiment, the lower interior of both the coarse washing tank 3 and the fine washing tank 4 is configured as an inclined surface structure that slopes towards the feed inlet 17, which allows impurities to gather at the feed inlet 17.

[0028] As a technical optimization of this utility model, the lower end of the sedimentation tank 5 is set as a conical structure.

[0029] In this embodiment, the lower part of the sedimentation tank 5 is set as a conical structure, which allows the sedimentation tank 5 to converge towards the sludge discharge pipe 9.

[0030] As a technical optimization of this utility model, the water pump 10, the first drive motor 15 and the second drive motor 20 are all electrically connected to an external control computer.

[0031] In this embodiment, the water pump 10, the first drive motor 15, and the second drive motor 20 can be controlled by an external control computer.

[0032] The working principle and usage process of this utility model are as follows: Porcelain clay raw material and water are added to the coarse washing tank 3. Then, the first drive motor 15 drives the rotating shaft 13 to rotate, which in turn drives multiple stirring rods 14 to rotate, thereby stirring the porcelain clay raw material. This causes heavy impurities such as quartz and iron filings to quickly settle to the bottom slope of the coarse washing tank 3. Simultaneously, light floating soil in the slurry is stirred and separated. The slurry after coarse washing then automatically overflows through the overflow port 7 into the fine washing tank 4. The stirring mechanism in the fine washing tank 4 operates at a higher speed, deeply emulsifying and scrubbing the slurry, further removing light and fine impurities such as fine mica and organic matter attached to the surface of the porcelain clay particles. During this process, the remaining medium-density impurities such as fine sand also settle. In the coarse washing tank 3 and the fine washing tank 4, the impurities separated by stirring settle under their own gravity. Thanks to the inclined structure of the tank bottom towards the feed inlet, the settled impurities are naturally guided and collected in the feed inlet. The material enters the conveying cylinder 16 through the feed inlet 17, and then the second drive motor 20 drives the spiral conveyor blade 19 to rotate. The spiral conveyor blade 19 transports the impurities that enter the conveying cylinder 16 through the feed inlet 17 to the discharge trough 18, and then discharges them through the discharge trough 18. The pure porcelain clay slurry after fine washing overflows into the sedimentation tank 5. The inclined tube packing group 8 provides a huge settling area. Based on the "shallow sedimentation principle", it greatly accelerates the settling speed of porcelain clay particles, so that mud and water are quickly separated. The clarified water enters the water storage tank 6 through the overflow port 7. The settled porcelain clay is further concentrated into high-density mud in the conical structure at the bottom of the sedimentation tank 5. When the mud is needed, the valve on the mud discharge pipe 9 is opened, and the concentrated mud is discharged under static pressure for subsequent production. The clarified water collected in the water storage tank 6 is pumped back to the coarse washing tank 3 by the water pump 10 through the return pipe 11 as cleaning water.
