[0026] The present invention will be described in detail below with reference to the attached drawings, along with embodiments.

[0027] As shown in Figures 1 to 3, the mixing apparatus 100 of the present invention, which is suitable for high-solids slurry, consists of a mixing tank 101, a supply pipe 102, a mixing paddle 113, a mixing spindle 103, and a mixing motor (not shown).

[0028] Specifically, the mixing tank 101 has a mixing space 101a and a supply pipe 102 having a powder inlet 102a, a liquid inlet 102b, and a supply passage 102c that communicate with the mixing space 101a, and is configured so that powder and liquid are supplied to the mixing space 101a via the supply passage 102c.

[0029] Specifically, the mixing paddle 113 is rotatably mounted within the mixing space 101a and is for homogeneously stirring and mixing the powder and liquid mixture within the mixing space 101a. The mixing spindle 103 extends at least partially into the mixing space 101a and forms an anti-rotation connection with the mixing paddle 113. The mixing spindle 103 is driven (directly or indirectly) by a mixing motor to rotate around its central axis, thereby rotating the mixing paddle 113 and enabling high-speed mixing of the powder and liquid mixture within the mixing space 101a. The slurry formed after homogeneous mixing is discharged from the outlet 1011d. Note that the outlet 1011d is closed during mixing.

[0030] In reality, the powder that enters the supply channel 102c tends to agglomerate. This affects the passability within the supply channel 102c, and if supplied directly to the mixing space 101a, it may have a significant impact on the dispersion efficiency.

[0031] As a preferred embodiment, as shown in Figures 1 to 4, the mixing apparatus 100 of the present invention, suitable for high-solids slurry, comprises a supply paddle member 104, a supply spindle 105, a supply motor 106, and a reduction gear 114. The supply spindle 105 extends at least partially into the supply passage 102c. The supply motor 106 cooperates with the reduction gear 114 to drive the supply spindle 105 within the supply passage 102c. The supply paddle member 104 is rotatably positioned within the supply passage 102c and attached to the supply spindle 105. By rotating together with the supply spindle 105, the supply paddle member 104 mixes and crushes the powder that enters the supply passage 102c at least from the powder inlet 102a.

[0032] In a preferred embodiment, as shown in Figures 2 and 4, the supply pipe 102 has a plurality of powder inlets 102a. These powder inlets 102a are arranged at different positions in the circumferential direction to simultaneously feed in the same powder or different types of powder. The supply paddle member 104 thoroughly grinds and mixes the fed powder.

[0033] As a specific embodiment, as shown in Figure 5, the supply paddle member 104 consists of a sleeve portion 1041, a helical portion 1042, and a connecting portion 1043. The sleeve portion 1041 is fitted onto the supply spindle 105, connected to the supply spindle 105 via a key, and fitted onto the supply spindle 105 in a way that prevents rotation. A step portion 1051 is formed on the supply spindle 105. This limits the mounting position of the sleeve portion 1041 on the supply spindle 105. The helical portion 1042 is configured to extend substantially along a spiral. The numerous connecting portions 1043 spirally connect the helical portion 1042 and the sleeve portion 1041 around the sleeve portion 1041, and the rotation of the connecting portions 1043 slices the powder in the supply passage 102c and uniformly mixes the powder. More specifically, the combination of the helical section 1042 and the connecting section 1043 is uniformly arranged in multiple groups around the central axis to improve slitting efficiency. The helical section 1042 and the connecting section 1043 adopt a streamlined structural design, with a rounded, smooth appearance that reduces resistance to powder, enabling rapid and uniform mixing of powder in narrow spaces, and preventing powder from accumulating in the supply path 102c.

[0034] In the preparation of high-solids-content, high-viscosity slurries, the particle size of the powder becomes smaller and the specific surface area increases, leading to increased adsorption of gases on the surface. This makes it difficult for the powder to penetrate the liquid, resulting in difficulties in uniform mixing and dispersion, and making problems such as peeling, aggregation, and precipitation more likely. Directly adding the powder to the mixing space 101a results in poor mixing efficiency and is time-consuming.

[0035] As a preferred embodiment, as shown in Figures 2 to 8, the mixing apparatus 100 of the present invention, suitable for high-solids slurry, further comprises an infiltration tube 107, a plurality of infiltration paddles 108, and a plurality of infiltration columns 109.

[0036] As shown in Figures 1 and 2, the infiltration pipe 107 has an infiltration passage 107a that communicates with the supply passage 102c, and the infiltration passage 107a is located between the supply passage 102c and the mixing space 101a.

[0037] As shown in Figure 1, the liquid inlet 102b is located in a different axial position from the powder inlet 102a, and the liquid inlet 102b is located in the supply passage 102c, which is close to the infiltration passage 107a. This allows the liquid to enter the infiltration passage 107a quickly after being supplied from the liquid inlet 102b.

[0038] As shown in Figures 2 to 4, the infiltration paddles 108 are provided within the infiltration passage 107a so as to rotate around their central axis. These infiltration paddles 108 are positioned at different axial locations within the infiltration passage 107a to mix the powder and liquid mixture during rotation. In this invention, the axial, radial, and circumferential directions are relative positions with respect to the central axis.

[0039] Multiple infiltration columns 109 are cylindrical structures extending radially along a central axis and are positioned between two infiltration paddles 108. The mixture of powder and liquid material flowing along the infiltration path 107a is divided in the infiltration columns 109. Specifically, the numerous infiltration columns 109, positioned between the two infiltration paddles 108, are located at different circumferential positions, and the infiltration columns 109 are positioned between the supply spindle 105 and the infiltration tube 107.

[0040] Using the above method, under the stirring of the infiltration paddle 108, the mixture of powder and liquid material, separated by multiple infiltration columns 109, is rotated completely so that the liquid material is thoroughly mixed with the powder. After continuous mixing of the infiltration paddle 108 and the infiltration columns 109, the majority of the infiltration can be completed, resulting in high infiltration efficiency.

[0041] Specifically, the gap between the infiltration paddle 108 and the infiltration column 109 is 3 mm to 5 mm, and the powder-liquid mixture is compressed between the infiltration paddle 108 and the infiltration column 109, accelerating the infiltration process.

[0042] In a specific embodiment, the infiltration paddle 108 includes a connecting shaft portion 1081 and a paddle portion 1082. The connecting shaft portion 1081 is fitted onto the supply spindle 105 and coupled to the supply spindle 105 to provide a rotation-preventing fit with the supply spindle 105. Multiple infiltration paddles 108 are sequentially inserted onto the supply spindle 105, with one connecting shaft portion 1081 of the infiltration paddle 108 approaching the sleeve portion 1041, and an end cap 111 is attached to the end of the supply spindle 105 to completely fix the connecting shaft portion 1081 in position relative to the spindle. The immersion paddle 108 and the supply paddle member 104 are connected to the same supply spindle 105, and as they rotate together, the rate at which powder is introduced into the immersion passage 107a and the rate at which the mixture is output to the mixing space 101a are made approximately equal. This avoids the accumulation of the mixture due to the powder being introduced into the immersion passage 107a being too fast, and the negative pressure space and accumulation of liquid that occur at the junction between the immersion passage 107a and the supply passage 102c when the output rate of the mixture is too fast, thereby facilitating the realization of metering control.

[0043] The paddle portions 1082 of the infiltration paddle 108 are arranged symmetrically with respect to opposing central axes at circumferential positions of the connecting shaft portion 1081. The paddle portions 1082 have paddle surfaces inclined to intersect with the central axis, and as the infiltration paddle 108 rotates, it applies both axial force along the central axis and centrifugal force to the powder-liquid mixture in the infiltration path 107a. The axial force pushes a portion of the powder-liquid mixture toward the infiltration column 109, and the centrifugal force pushes another portion of the mixture toward the inner wall of the infiltration tube 107.

[0044] Specifically, the gap between the paddle portion 1082 and the inner wall of the infiltration tube 107 is 3 mm to 5 mm, and the mixture of powder and liquid is pushed toward the inner wall of the infiltration tube 107 by centrifugal force, constricting it between the paddle portion 1082 and the infiltration tube 107, further accelerating the infiltration process.

[0045] In a preferred embodiment, as shown in Figure 6, the paddle surface of the paddle section 1082 is configured to have at least one curved surface, thereby reducing the resistance when the paddle surface comes into contact with the mixture, allowing the mixture to flow smoothly over the paddle surface and promoting mixing of the mixture. Specifically, the paddle surface of the paddle section 1082 is divided into a positive paddle surface 1082a and a negative paddle surface 1082b, which are located on both sides of the paddle section 1082, respectively. The positive paddle surface 1082a provides thrust to the mixture, and the negative paddle surface 1082b divertes the flow of the mixture through the paddle section 1082.

[0046] Specifically, the paddle section 1082 further includes a transition surface 1082c. As shown in the figure, the transition surface 1082c is located between the positive paddle surface 1082a and the negative paddle surface 1082b and intersects the central axis at an angle. In this manner, a portion of the mixture pushed by the positive paddle surface 1082a flows toward the transition surface 1082c near the side of the mixing space 101a, thereby kneading this portion of the mixture between the transition surface 1082c and the mixing infiltration column. Furthermore, the transition surface 1082c near the side of the supply channel 102c forms a contact angle 1082d with the positive paddle surface 1082a. The contact angle 1082d divides the mixture in the infiltration channel 107a as the paddle section 1082 rotates, causing a portion of the mixture to flow along the transition surface 1082c on this side, further promoting the mixing of the mixture.

[0047] As shown in Figures 3, 7, and 8, in a preferred embodiment, a number of flanged pipes 1071 are sequentially connected to the infiltration pipe 107 to form the infiltration pipe 107, and the infiltration paddle 108 is housed in the space surrounded by the flanged pipes 1071. Installation of the infiltration paddle 108 and the infiltration pipe 107 is achieved by sequentially attaching them to the supply spindle 105, and assembly is easy.

[0048] In a preferred embodiment, the mixing device 100 suitable for the high-solids slurry of the present invention has a wetting ring member 110. The mixing device 100 is configured to have a ring structure and is installed outside the supply spindle 105. The infiltration column 109 is connected at one end to the infiltration tube 107 and at the other end to the wetting ring member 110, integrally connecting coaxially positioned infiltration columns 109 and improving the robustness of the infiltration column 109.

[0049] As shown in Figure 1, in a preferred embodiment, the supply pipe 102 has a plurality of liquid inlets 102b located at different positions in the circumferential direction, so that the same fluid or different types of fluids can be supplied simultaneously, resulting in uniform fluid input to the wetting pipe in the circumferential direction and improved wetting efficiency.

[0050] As shown in Figures 3 and 4, in a preferred embodiment, a supply spindle 105 of a specific length is provided with a bearing housing 112 attached to the supply pipe 102. Thus, the reducer 114 is mounted in the bearing housing 112. The bearing housing 112 provides an internal space for mounting a number of bearings.

[0051] As shown in Figure 2, when a powder-liquid mixture is mixed by operating the mixing paddle 113 at high speed, a lot of heat is generated, and if the temperature continues to rise to a certain level, it can lead to the modification of the mixture. In a preferred embodiment, the mixing tank 101 has a cooling jacket 101b having a cooling chamber 1011a, an inlet port 1011b, and an outlet port 1011c. The cooling chamber 1011a is provided around the mixing space 101a, the inlet port 1011b is a port for cooling water to flow into the cooling chamber 1011a, and the outlet port 1011c is a port for cooling water to flow out of the cooling chamber 1011a, removing excess heat from the mixing space 101a and preventing the temperature from rising and the slurry from modifying. Specifically, the mixing tank 101 consists of an outer tank 1011 and an inner tank 1012, and the cooling jacket 101b is configured between the outer tank 1011 and the inner tank 1012.

[0052] Specifically, the mixing tank 101 consists of an inlet pipe 1013 and an outlet pipe 1014, with an inlet port 1011b provided in the inlet pipe 1013 and an outlet port 1011c provided in the outlet pipe 1014. The inlet pipe 1013 extends radially to a region near the central axis, increasing the residence time of the cooling water supplied from the inlet port 1011b to the cooling chamber 1011a, thereby absorbing sufficient heat and improving heat dissipation.

[0053] As shown in Figures 9 to 12, in a specific embodiment, the mixing paddle 113 consists of a dispersion disk 116, a number of dispersion columns 117, and a guide cone 118. The dispersion disk 116 consists of a central portion 1161 and a number of paddle block portions 1162 provided around the central portion 1161. The central portion 1161 is configured to be center-symmetric with respect to the central axis.

[0054] Multiple dispersion columns 117 rotate in sync with the paddle block section 1162 and are separately located on the paddle block section 1162. A guide cone 118 is located above the central section 1161, forming a first discharge surface 1181. This improves the fluidity of the mixture after the slurry on top of the dispersion disk 116 has been induced and dispersed, and improves the flow to the dispersion disk 116.

[0055] The dispersion column 117 rotates at high speed on the dispersion disk 116, shearing and dispersing the powder-liquid mixture and propelling it at high speed towards the inner wall of the inner tank 1012. Because the rotation speed is lower in the intermediate zone located on the side of the dispersion column 117 closer to the central axis, the mixture at the top of the tank space falls down to fill the intermediate zone, increasing the fluidity of the mixture in the tank space.

[0056] The dispersion disk 116 has a mounting hole 116b for insertion into one end of the mixing spindle 103, and a fitting inner surface 116c formed around the dispersion axis. The portion of the mixing spindle 103 that is inserted into the mounting hole 116b has a fitting outer surface 1031 formed around the spindle axis. After being inserted into the mounting hole 116b and pressed, the fitting outer surface 1031 and the fitting inner surface 116c form an interlocking fit, causing the dispersion disk 116 to rotate due to friction.

[0057] Specifically, the paddle block section 1162 is configured to have a positive guide surface 1163 and a negative guide surface 1164. The positive guide surface 1163 and the negative guide surface 1164 are provided on both sides of the paddle block section 1162 and are both inclined to intersect with the central axis. A guide passage 116a is provided between the positive guide surface 1163 and the negative guide surface 1164 of the paddle block section 1162. The guide passage 116a penetrates the dispersion disk 116 axially so that at least a portion of the slurry is guided to the bottom of the dispersion disk 116 when the dispersion disk 116 rotates. Specifically, the first discharge surface is configured to be at least part of a conical surface, thereby enhancing the flow guide effect of the first discharge surface.

[0058] In the above method, when the paddle block section 1162 rotates, the forward guide surface 1163 cuts a portion of the mixture and pushes it toward the bottom of the tank space, promoting the flow of the mixture, while the reverse guide surface 1164 guides the mixture as it passes through the guide passage 116a.

[0059] As shown in Figures 10 and 11, in a preferred embodiment, the positive guide surface 1163 is inclined to intersect the radial direction of the central axis, and by rotating, it applies a radial force to the mixture flowing through the guide channel 116a, throwing the mixture out and increasing the fluidity of the mixture. Specifically, the positive guide surface 1163 is configured as a streamlined curved surface.

[0060] In a preferred embodiment, the inverted guide surface 1164 is inclined to intersect the central axis radially, and by rotating, it guides a portion of the mixture flowing through the guide channel 116a radially, thereby increasing the fluidity of the mixture. Specifically, the inverted guide surface 1164 is configured as a streamlined curved surface. The streamlined curved surface helps to reduce air resistance.

[0061] In a preferred embodiment, the projected area of ​​the positive guide surface 1163 in a projection plane perpendicular to the central axis is less than or equal to the projected area of ​​the negative guide surface 1164 in a projection plane perpendicular to the central axis. This causes the slurry to be gradually compressed as it enters the guide path 116a and guided to the bottom of the distributed disk 116.

[0062] In a preferred embodiment, the upper surface of the paddle block portion is curved. The tops of the numerous paddle block portions 1162 are configured to be curved, thereby reducing the slurry's resistance to the dispersion disk 116.

[0063] As shown in Figures 10 and 12, in a preferred embodiment, the dispersion column 117 includes a column top 1171 and a column bottom 1172, the column top 1171 being located above the paddle block portion 1162 and the column bottom 1172 being located below the paddle block portion 1162. The dispersion column 117 has at least a cylindrical surface parallel to the central axis.

[0064] As shown in Figures 2 and 13, in a preferred embodiment, the mixing apparatus 100 further comprises baffles 115 for stopping the circumferential flow of slurry, driven by the mixing paddles 113, at the inner wall of the mixing tank 101. A number of axially extending baffles 115 are provided at different circumferential positions on the inner wall of the mixing tank. The baffles 115 guide a portion of the circumferentially rotating slurry upward, so that the slurry not only rotates circumferentially due to the action of the dispersion disks 116 and dispersion columns 117, but also rolls up and down, improving the mixing effect.

[0065] Optionally, the baffle plate 115 is fixed or rotatably mounted on the inner wall of the mixing tank. Here, the rotation setting adjusts the inclination angle of the baffle plate 115 for different dispersion speeds.

[0066] As shown in Figures 9 to 12, the projection of the bottom surface of the dispersion disk 116 onto a projection plane perpendicular to the dispersion axis is a straight line, and the gap between it and the bottom surface of the inner tank 1012 forms a pinch region. Due to the rapid reduction in space, the mixture is squeezed by the bottom surface of the dispersion disk 116 and the bottom surface of the inner tank 1012 as it enters the kneading region, improving the kneading effect.

[0067] To ensure the passage of the mixture through the guide path 116a, the forward guide surface 1163 and the reverse guide surface 1164 are connected by a connecting surface 1165, and a gap is left between the forward guide surface 1163 and the reverse guide surface 1164.

[0068] A conical boss 1166 is formed in the central part 1161. The guide cone 118 is attached to the boss 1166, and a second discharge surface 1166a is formed on the boss 1166. The taper of the second discharge surface 1166a is the same as that of the first discharge surface, allowing the slurry to flow smoothly from the surface of the guide cone 118 to the dispersion disk 116.

[0069] Intersecting flow guide outer edges are provided on the second discharge surface and the upper surface of the dispersion disk 116. Intersecting transition outer edges are provided on the connection surface 1165 and the upper surface of the dispersion disk 116. In this way, at least a portion of the transition outer edge and the flow guide outer edge overlap, and the slurry flowing into the guide cone 118 is directly guided to the guide path 116a, improving the flow effect.

[0070] The above description is limited to exemplifications of some preferred embodiments of the present disclosure and applicable technical principles. Those skilled in the art will understand that the scope of the invention relating to embodiments of the present disclosure is not limited to technical solutions obtained from specific combinations of the above-described technical features, but also includes other technical solutions formed by any combination of the above-described technical features or their equivalents, without departing from the inventive concept.
