Description

Technical Field

[0001] The present invention relates to the technical field of ceramic production, in particular to a ceramic material strengthening process based on nanotechnology. Background Art

[0002] Although the existing production process of ceramic materials has become relatively mature after years of development, there are still many shortcomings in further improving the mechanical properties, toughness and comprehensive application performance of ceramic materials. First of all, although the hardness of ceramic materials is relatively high, due to their high brittleness, they are prone to cracking or breaking under external forces, which limits their use in certain special application scenarios. In existing processes, in order to improve the performance of ceramics, sintering conditions are often adjusted or some reinforcing materials are added, but the effects of these methods are often limited, and there is a lack of systematic strengthening solutions.

[0003] In actual ceramic production, mixing ceramic powders is a critical step. However, in traditional mixing processes, ceramic powder particles tend to agglomerate during mixing, forming large clumps of powder. Such agglomerations not only affect subsequent processing and sintering but also lead to uneven heating of the material during sintering. This unevenness directly affects the density and internal structure of the ceramic product, thereby reducing the overall strength and toughness of the material, resulting in poor mechanical properties of the final product, high scrap rates, and inconsistent quality.

[0004] Furthermore, the design of traditional mixing equipment often faces certain limitations in actual production. Due to its complex structure, mixing equipment is easily blocked by foreign objects or large particles during operation, causing equipment downtime or even damage. This not only affects production continuity, but also increases maintenance costs and downtime, significantly reducing production efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0022] The following combination Figure 1-Figure 5 , and further illustrate the technical solution of the present invention through specific implementation methods.

[0023] The present invention provides a ceramic material strengthening process based on nanotechnology, comprising the following steps: S1, adding ceramic powder doped with aluminum and magnesium components into a heating cylinder 109, wherein the doping with aluminum and magnesium can improve the mechanical properties of the ceramic, increase its toughness and strength; S2, driving the mixing blade 118 to stir the ceramic powder by rotating the mixing part, breaking up powder agglomerates, promoting uniform distribution of particles, and improving sintering uniformity; S3, starting the induction heating coil surrounding the heating cylinder 109, and heating the ceramic powder to a sintering temperature; S4, driving the mixing part to rotate by a driving part, wherein the driving part can prevent the entire equipment from malfunctioning due to foreign matter being stuck in the mixing part during the stirring of the ceramic powder; S5, driving the swing arm 102 to swing by the unloading electric cylinder 104, so that the heating cylinder 109 follows the swing, and the ceramic melt inside the heating cylinder 109 is melted. The liquid is poured out. During this process, the telescopic cylinder of the unloading electric cylinder 104 will move relative to the support frame 101, and the telescopic rod of the unloading electric cylinder 104 will move relative to the swing arm 102, swinging the heating cylinder 109 to an inclined state so that the top opening is tilted downward to pour out the ceramic melt. In this process, the engaging protrusion 115 needs to be swung to a position with the same swing direction as the heating cylinder 109. Specifically, the electromagnet 105 can be started. The electromagnet 105 generates a magnetic force to attract the positioning magnet 107, and the positioning magnet 107 will move toward the direction of the electromagnet 105, thereby driving the driving active shaft 116 to swing through the torque arm 108. Therefore, as long as the electromagnet 105 is started, the engaging protrusion 115 will be driven to swing to the correct position, ensuring that the engaging protrusion 115 and the engaging groove 114 can be smoothly separated and engaged. The mixing section includes a heating tube 109, which is composed of an induction heating coil and a graphite crucible. Ceramic powder doped with aluminum and magnesium is added to the graphite crucible. A shaft tube bracket 110 is fixed to the top of the inner wall of the heating tube 109. A shaft tube 111 is fixed to the shaft tube bracket 110. A stirring shaft 113 is rotatably mounted on the shaft tube 111. A plurality of mixing blade connectors 117 are equidistantly arranged along the stirring shaft 113 along its own axial direction. Each mixing blade connector 117 is symmetrically fixed with two mixing blades 118 about the axis of the stirring shaft 113. The two mixing blades 118 are angled with the horizontal plane. Each mixing blade 118 is also fixed with an edge blade 119 at the end away from the mixing blade connector 117, generating axial and radial mixing flows to enhance the mixing effect of the ceramic powder. The two mixing blades 118 at the bottom are fixed with top center blades 122 through vertical connecting pieces 120. The two top center blades 122 are symmetrically arranged about the axis center of the stirring shaft 113. A bottom edge blade 121 is fixed at one end of each top center blade 122 away from the axis center of the stirring shaft 113 to ensure that the ceramic powder at the bottom of the heating cylinder 109 can also be fully stirred to avoid material deposition.A supporting rotating ring 103 is fixedly sleeved on the outer surface of the heating cylinder 109, and the supporting rotating ring 103 is rotatably installed on the support frame 101. The support frame 101 is fixed on the base 127. The side of the support frame 101 is also rotatably equipped with a swing arm 102 fixed to the supporting rotating ring 103. A unloading electric cylinder 104 is movably installed on the top of the support frame 101. The end of the telescopic rod of the unloading electric cylinder 104 is movably connected to the swing arm 102, which is used to drive the swing arm 102, the supporting rotating ring 103 and the heating cylinder 109 to swing.

[0024] A driving active shaft 116 is rotatably installed on the top of the support frame 101, and an engaging protrusion 115 is fixed to the bottom end of the driving active shaft 116, wherein an engaging concave block 112 is fixed to the top end of the stirring shaft 113, and an engaging groove 114 is provided on the engaging concave block 112, and the engaging groove 114 is spline-fitted with the engaging groove 114 and the engaging protrusion 115; wherein a torque arm 108 is fixed to the top end of the driving active shaft 116, and a positioning magnetic block 107 is fixed to the end of the torque arm 108 away from the driving active shaft 116, and an electromagnet 105 is fixed to the support frame 101 through an electromagnet bracket 106, and the electromagnet 105 and the positioning magnetic block 107 are magnetically fitted. The support frame 101 also secures a gearbox 124 and a drive protection chamber 125. The output shaft of the gearbox 124 is connected to the driving shaft 116 via a transmission chain 123. The inner wall of the drive protection chamber 125 is secured to a plurality of circular connecting support plates 139. An inner flow guide duct 136, coaxial with the drive protection chamber 125, is secured to the inner wall. Curved sealing covers 132 are secured to the top and bottom openings of the drive protection chamber 125. Coaxially mounted active drive impellers 137 and passive drive impellers 138 are rotatably mounted within the inner flow guide duct 136. A drive motor 126 is secured to the base 127. The output shaft of the drive motor 126 is secured to the active drive impeller 137, while the input shaft of the gearbox 124 is secured to the passive drive impeller 138. The input shaft of the gearbox 124, the output shaft of the drive motor 126, and the curved sealing covers 132 all form a rotating seal. A heat conducting block 128 is fixed to the outer surface of the drive protection chamber 125. A heat sink 130 is mounted overhead on this block. A secondary cooling plate 135 is coupled to the heat conducting block 128 via thermal grease. The interior of the secondary cooling plate 135 utilizes a hollow, negative pressure chamber filled with coolant. A wind deflector 129 is fixed to the heat sink 130. A cooling fan bracket 134 is fixed to the wind deflector 129. A cooling fan 131 is rotatably mounted on this bracket 134. This fan 131 is connected to the input shaft of the gearbox 124 via a heat dissipation belt 133.

[0025] The working principle of a ceramic material strengthening process based on nanotechnology disclosed in the present invention is as follows: when in use, the drive motor 126 is started, and the output shaft of the drive motor 126 drives the active drive impeller 137 to rotate, and the active drive impeller 137 drives the fluid inside the inner guide tube 136 to move (liquid or gas can be used), and the fluid drives the driven drive impeller 138 to rotate (and then converges to one end of the active drive impeller 137 through the gap between the outer surface of the inner guide tube 136 and the inner surface of the drive protection chamber 125 to form a circulating flow of the fluid), the driven drive impeller 138 drives the input shaft of the gearbox 124 to rotate, and the output shaft of the gearbox 124 drives the driving shaft 116 to rotate through the transmission chain 123, and the driving shaft 116 drives the engaging protrusion 115 and the engaging recess The groove 114 drives the stirring shaft 113 to rotate, the stirring shaft 113 drives the mixing blade connector 117 to rotate, the mixing blade connector 117 drives the mixing blade 118 to rotate and the edge blade 119 to rotate, as well as the top center blade 122 and the bottom edge blade 121 at the bottom to rotate. The mixing blade 118, the edge blade 119, the bottom edge blade 121 and the top center blade 122 will drive the ceramic powder inside the heating tube 109 to mix and stir, among which the mixing blade 118 and the top center blade 122 will drive the ceramic powder to move upward along the axial direction of the stirring shaft 113, while the edge blade 119 and the bottom edge blade 121 will drive the ceramic powder at the edge of the heating tube 109 to move downward along the axial direction of the stirring shaft 113, forming a cycle, which is conducive to uniform mixing of the ceramic powder.

[0026] In addition, the user can activate the secondary refrigeration sheet 135. The cooling surface of the secondary refrigeration sheet 135 will transfer the low temperature to the thermal block 128. The thermal block 128 then transfers the low temperature to the drive protection chamber 125, cooling the fluid medium inside the drive protection chamber 125 to increase its density (the arc-shaped sealing cover 132 has a certain toughness and can deform accordingly with the expansion or contraction of the fluid medium inside the drive protection chamber 125). This will increase the density of the fluid inside the drive protection chamber 125, thereby increasing the force transmitted from the active drive impeller 137 to the driven drive impeller 138, and further increasing the torque at the output shaft end of the gearbox 124. At this time, the mixing blade 118 and the top center blade 122 can mix a larger mass of ceramic powder. The temperature of the heating surface of the secondary refrigeration plate 135 will be transferred to the heat sink 130. As the heat sink 130 heats the internal coolant, the boiling point of the coolant is low due to the negative pressure. At this time, the coolant will absorb heat and evaporate. It should be noted that the coolant occupies half of the internal space of the heat sink 130. The evaporated coolant will move to the top of the heat sink 130 for condensation and then fall back downward. This process requires the cooling fan 131 to rotate, move the external cold air to the heat sink 130, and dissipate heat from the heat sink 130, thereby ensuring that the coolant can condense quickly. The rotation of the cooling fan 131 is connected to the input shaft of the gearbox 124 through the heat dissipation transmission belt 133. Therefore, the operation of the gearbox 124 can drive the cooling fan 131 to rotate. At the default ambient temperature, the medium density inside the drive protection chamber 125 is relatively small, so the force of the active drive impeller 137 to drive the driven drive impeller 138 to rotate is relatively small, resulting in a relatively small torque at the output end of the gearbox 124. Therefore, the load torque on the stirring shaft 113 can be controlled by the refrigeration secondary plate 135. When the mixing blade connecting seat 117, the mixing blade 118, the edge blade 119, the vertical connecting plate 120, the bottom edge blade 121 and the top center blade 122 are stuck due to foreign objects, the driven drive impeller 138 can stop rotating, causing the active drive impeller 137 to idle, thereby activating the protection function.

[0027] At the same time, in addition to adding aluminum and magnesium to the ceramic powder, users can also dope graphene nanosheets inside, and adjust the direction of the graphene nanosheet plane according to the force direction of the ceramic material so that it is parallel to the force direction. This allows the sintered ceramic material to withstand greater tensile strength. Specifically, the ceramic powder mixed with graphene nanosheets is placed in an electromagnetic field. Under the action of the electromagnetic field, the graphene nanosheets will be oriented and arranged, improving the mechanical and functional properties of the material. This is because graphene nanosheets have obvious shape anisotropy (thin sheet) and electromagnetic anisotropy (high conductivity in the plane, low conductivity in the vertical direction). This characteristic causes it to produce orientation behavior under the action of an electromagnetic field. Under the action of an electromagnetic field, the graphene nanosheet will generate an induced dipole moment, causing it to align along the direction of the electric field. The interaction between the induced dipole moment and the applied electric field will generate a torque on the nanosheet, causing it to rotate to the lowest energy orientation state, that is, the plane is perpendicular to the direction of the electric field.
