Description

Technical Field

[0001] The utility model relates to the technical field of equipment related to ceramic film production, and more specifically to a stirring device for increasing the plasticity of mud materials. Background Art

[0002] During the preparation of ceramic membranes, the plasticity of the clay directly affects the quality of vacuum extruded products. The process of clay forming a plastic mud ball is: the completely dry powdered clay is mixed with a small amount of water at the beginning, and its physical properties do not change much, and it does not show plasticity and is still not loose. Continue to add water and mix. When the clay particles are in a water environment, a little external force is applied to make the water ions be adsorbed to the surface of the clay particles, and a water structure layer is established around the surface of the clay particles. The OH- ions are adsorbed to the surface of the oxygen ions, and the surface of the clay particles is tightly wrapped with a very thin "water film". The adjacent clay particles are "huggled into a ball" by the cohesive force of water, and the clay becomes plastic. The external force is removed without deformation. At this time, the water content of the clay is called the plastic limit, or plastic limit for short. If water is continued to be added and mixed at this time, the clay becomes softer and softer until it becomes a flowing mud. At this time, the water content of the clay is called the liquid index, or liquid limit for short.

[0003] Obviously, only when the moisture content of the clay is between its plastic limit and liquid limit can it be extruded and formed. The wider the range, the easier it is to form the clay, and vice versa. It can be seen that the clay needs to be formed into a plastic mass by applying external force, that is, stirring and forming. The stirring increases the plasticity of the clay so that it can be extruded and formed. However, there is no targeted clay plastic stirring device on the market. The ordinary stirring device drives the stirring shaft through the motor to rotate the stirring rod for stirring. The stirring efficiency is low, the stirring effect is poor, and the stirring is not uniform, which affects the quality of the subsequent extruded products. Utility Model Content

[0037] The working principle and use process of this utility model:

[0038] The initial state of this utility is Figure 1 As shown, first, mud and water are added into the mixing box through the material inlet 201, and the two driving rods 302 are driven to rotate by the dual-axis motor 301. The driving rods 302 rotate the rotating shaft 2023 through the active disk 303, the transmission belt 305 and the driven disk 304; the rotating shaft 2023 synchronously drives the rotating drum 2022 and the cross connecting plate 2031 to rotate during the rotation. During the rotation of the rotating drum 2022, the stirring rod 2024 and the stirring shaft on the stirring rod 2024 are driven to rotate around the rotating shaft 2023. When the cross connecting plate 2031 rotates, the rotating rod 2032 follows and performs circumferential motion. During circumferential motion, the toothed disc 2034 sleeved on its outer wall and the inner gear ring 2033 mesh, thereby driving the toothed disc 2034 to rotate, and the toothed disc 2034 drives the rotating rod 2032 to rotate the active bevel gear 2035, thereby driving the driven bevel gear 2036 to drive the stirring rod 2024 to rotate. The stirring rod 2024 can rotate while following the rotating drum 2022 to rotate circumferentially around the rotating shaft 2023, and the two sets of stirring mechanisms 202 are symmetrically arranged, so that the mud can be stirred from different directions, so that the stirring efficiency is improved, the stirring effect is better and more uniform, thereby quickly increasing the plasticity of the mud.

[0039] After the plasticity of the mud is increased by stirring so that it can be extruded and formed, the hydraulic cylinder 403 is extended and retracted to push and pull the axle pin 402 through the connecting piece 404. The axle pin 402 rotates the support shaft 101 through the lever 401. As the support shaft 101 rotates, the connecting frame 102 drives the mixing barrel 200 to rotate, so that the material port 201 is tilted downward to facilitate the pouring of the mud.

[0040] The electronic components and modules used in the content of this utility model can all be parts that are commonly used in the market and can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs. The electronic components and modules are all connected to an external power supply and a control switch for use. Their specific circuit connection methods and methods of use are commonly used public technologies and will not be elaborated on here.

[0041] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
