Technical Field

[0001] The invention relates to the technical field of stirring equipment, and in particular to a stirring device. Background Art

[0002] In a current color paste preparation process, iron oxide powder is mixed with a variety of solvents and placed in a mixing barrel, stirred and pumped into a roller compactor through a vacuum pump for compaction, and then returned to the mixing barrel for multiple cycles to complete the stirring operation, so that the iron oxide powder in the mixed solvent is completely dissolved and the solvent forms a fine water solution. During the stirring operation, since the iron oxide powder is easily present in a clumping form and unevenly distributed after mixing, the current stirring equipment cannot focus on stirring the part where the iron oxide powder is more clumping when in use, resulting in low overall efficiency.

When the ring body moves upward, the ring body can be separated from the through hole to open the upper end of the through hole.

[0005] Furthermore, the ring body is annular, the inner peripheral wall of the ring body is fixedly connected to the two outer walls of the rod body, and the outer diameter of the ring body is the same as the inner diameter of the through hole.

[0006] Furthermore, the collar also includes an extension portion located below the ring body, the upper cross-section of the extension portion is arc-shaped, the upper outer wall of the extension portion is arc-shaped, and the lower radial outer end of the extension portion is a sharp angle.

[0007] Furthermore, the bottom of the extension portion is located below the through hole.

[0008] Furthermore, the rotating block is provided with a cavity.

[0009] Furthermore, a fixing piece is installed on the second outer wall of the rod body, and the fixing piece is provided with a tip portion, which is a linear tip along the second circumference of the rod body, and the tip portion can be inserted into the through hole.

[0010] Furthermore, a rod body 1 is installed at the bottom of the rotating block, a chassis is installed at the bottom of the rod body 1, the chassis is located below the fixed plate, the chassis and the rod body 1 are connected through a bearing 1, a fixing ring is installed at the upper end of the chassis, the fixing ring is connected to the rod body 2 through a bearing 2, the rod body 2 and the through hole are arranged one by one, the rod body 2 is evenly distributed along the circumference of the chassis, and the rod body 1, the chassis and the rotating block are all coaxially arranged.

[0011] Furthermore, a gear is installed on the outer wall of the first rod body, and a gear ring is installed on the outer wall of the second rod body, and the gear rings are both meshed with the gear.

[0012] Beneficial effects of the present invention:

[0013] 1. When there are more agglomerated solutes in the introduced color paste, they will gather at the through hole, causing blockage at the through hole wall and slowing down the flow of the color paste. At this time, the color paste solution in cavity one increases further, and the overall liquid level of the color paste solution rises, causing the rotating block to float further upward, thereby further reducing the flow rate of cavity one, thereby slowing down the flow rate of the color paste in cavity one, and the distance between the wall and the inner wall of channel two is closer. Due to the rotation of the rotating block, the color paste is squeezed by the combined action of the wall and the inner wall of channel two, which is conducive to better crushing the agglomerated solutes in the color paste under pressure, making the color paste more delicate.

[0014] 2. Due to the blockage at the through hole wall, the residence time of the color paste in the cavity 1 increases, which increases the stirring time, and then the color paste carrying more agglomerated solutes obtains a better stirring effect. As the fixing part and the extension part clean the through hole wall, the through hole is unblocked, and when the color paste passes through the through hole, it is cut by the fixing part, and the agglomerated solute in the color paste is broken up, thereby improving the fineness of the color paste.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, a stirring device is used to stir the color paste solution. The color paste passes through the stirring device for multiple cycles to fully mix the agglomerated iron oxide powder in the color paste solution with the solvent. The stirring device includes a barrel body 1 and a rotating block 2. The barrel body 1 is provided with a channel 11, a channel 2 12, and a channel 3 13 from top to bottom. The top of the channel 11 passes through the top of the barrel body 1 and is the feed end. The incoming material is a preliminary mixed solution of the color paste. The bottom of the channel 11 is connected to the top of the channel 2 12. The channel 2 12 is a tapered hole with a small aperture at the upper end and a large aperture at the lower end. The bottom of the channel 2 12 is connected to the top of the channel 3 13. The bottom of the channel 3 13 passes through the barrel body 1 to facilitate the outflow of the color paste.

[0025] like Figure 1As shown, the main body of the rotating block 2 is a conical structure, and a cavity 22 is provided in the rotating block 2 so that the rotating block 2 can float in the color paste solution. The rotating block 2 is inserted into the barrel body 1, and the rotating block 2 passes through the second channel 12. The rotating block 2 is provided with a wall surface 24, and the wall surface 24 is at least partially located in the second channel 12. The wall surface 24 is a conical surface with a small diameter at the upper end and a large diameter at the lower end. The taper of the second channel 12 is the same as that of the wall surface 24. The gap between the inner wall surface of the second channel 12 and the wall surface 24 forms a cavity 16, and the lower end of the cavity 16 is connected to the third channel 13. The rotating block 2 can move up and down and can rotate along its own axis. Specifically, the rotating block 2 includes an end 21 located at the top, and the end 21 is slidably connected and inserted into the shaft body 7. The end 21 can move up and down along the inner wall of the shaft body 7. The outer wall of the end 21 is provided with a protrusion, and the shaft body 7 is provided with a corresponding groove. The protrusion of the end 21 is inserted into the groove of the shaft body 7, so that the shaft body 7 forms a limit on the rotation direction of the end 21. The top of the shaft body 7 is driven to rotate by a motor, and the end 21 is driven to rotate synchronously when the shaft body 7 rotates. When the end 21 is at the lower extreme position, it does not separate from the shaft body 7. Support feet 23 are installed at the bottom of the rotating block 2, and the support feet 23 are located on both sides of the rotating block 2, and the support feet 23 are located in the channel three 13.

[0026] like Figure 1 , Figure 2 As shown, a rod body 13 is also installed at the bottom of the rotating block 2, and a fixed disk 4 is installed at the hole 3 13. The fixed disk 4 is located below the support foot 23. The rod body 13 passes through the fixed disk 4. When the rotating block 2 moves up and down, the rod body 13 is driven to make the rod body 13 move up and down along the inner wall of the fixed disk 4. The fixed disk 4 is located in the hole 3 13. The fixed disk 4 divides the hole 3 13 into a cavity 1 131 and a cavity 2 132 from top to bottom. The cavity 1 131 is connected to the cavity 1 6. A plurality of countersunk holes 41 are provided at the upper end of the fixed disk 4. The countersunk holes 41 are evenly distributed along the circumference of the fixed disk 4. The bottom of the countersunk holes 41 is connected to a through hole 411. The through hole 411 runs through the bottom of the fixed disk 4. The cavity 1 131 is connected to the cavity 2 132 through the countersunk holes 41 and the through hole 411.

[0027] like Figure 2 As shown, a stirring plate 31 is installed on the outer wall of the rod body 3, and the stirring plate 31 is located between the top of the fixed plate 4 and the bottom of the rotating block 2. The rotating block 2 rotates to drive the rod body 3 to rotate, thereby causing the stirring plate 31 to rotate to stir the color paste in the cavity 131.

[0028] like Figure 2 As shown, a chassis 32 is installed at the bottom of the rod body 1 3, the chassis 32 is located below the fixed plate 4, the rod body 1 3 is inserted into the chassis 32, and the chassis 32 and the rod body 1 3 are connected through a bearing 1 321. A fixing ring 33 is installed at the upper end of the chassis 32, and a rod body 2 34 is connected in the fixing ring 33 through a bearing 2 331. The rod body 2 34 and the through hole 411 are arranged one by one, and the rod body 2 34 is evenly distributed along the circumference of the chassis 32. The rod body 1 3, the chassis 32, and the rotating block 2 are all coaxial.

[0029] The rod body 34 passes through the through hole 411. The outer wall of the rod body 34 is sleeved with a collar 5, which includes a ring body 51 and an extension portion 52 located below the ring body 51. Figure 3 , Figure 3 4 is a diagram showing the matching of the rod body 34 and the ring body 51. The ring body 51 is annular, and the inner wall of the ring body 51 is fixedly connected to the outer wall of the rod body 34. The outer diameter of the ring body 51 is the same as the inner diameter of the through hole 411. Figure 2 , Figure 4 The extension portion 52 is arranged along the axial direction of the rod body 34 in the length direction. Figure 4 4 is a diagram showing the matching between the upper portion of the second rod body 34 and the extension portion 52 . The cross section of the extension portion 52 is arc-shaped, the upper outer wall of the extension portion 52 is arc-shaped, and the bottom of the extension portion 52 extends to below the through hole 411 . Figure 4 FIG. 3 is a diagram showing the matching of the lower portion of the rod body 34 and the extension portion 52. The radial outer end of the lower portion of the extension portion 52 is a sharp angle. Figure 4 As shown, when the upper portion of the extension portion 52 is located in the through hole 411, the extension portion 52 rotates to agitate the color paste in the through hole 411. Figure 5 As shown, when the ring 5 rises, the lower part of the rod body 34 is located in the through hole 411. Since the radial outer end of the lower part of the extension part 52 is a sharp angle and the tip is a vertical straight line, the lower part of the extension part 52 cuts and breaks the agglomerated solute (i.e., agglomerated mixture formed by iron oxide powder and solvent with larger particles) blocking the inner wall of the through hole 411 in the process of spiral ascent, thereby preventing the through hole 411 from being blocked.

[0030] like Figure 2 , Figure 7 As shown, the outer wall of the rod body 34 is fixedly mounted with a fixing member 8, combined with Figure 5 The fixing member 8 is in an arc shape, and a tip 81 is provided on the outer wall of the fixing member 8. The tip 81 is a linear tip along the circumference of the rod body 34. There are multiple tips 81 evenly distributed above and below. In the initial state, the fixing member 8 is located below the through hole 411. When the rod body 34 rises, the fixing member 8 is inserted into the through hole 411, and the fixing member 8 rotates with the rod body 34, so that the tip 81 forms a horizontal cutting on the mass solute blocking the inner wall of the through hole 411 to break it, thereby preventing the through hole 411 from being blocked.

[0031] like Figure 2 As shown, when the rod body 1 3 moves up and down, the chassis 32 is driven to move, so that the rod body 2 34 can move up and down. The rod body 2 34 can rotate along its own axis. Specifically, a gear 36 is installed on the outer wall of the rod body 1 3, and the gear 36 is a gear ring. The outer wall of the rod body 2 34 is installed with a gear ring 35, and each gear ring 35 is meshed with the gear 36. Under the rotation of the rod body 1 3, the rod body 1 3 rotates along its own axis, so that the extension part 52 can stir the inner wall of the through hole 411 to prevent the mass solute from accumulating on the inner wall of the through hole 411 and affecting the fluidity.

[0032] Combination Figure 2 , Figure 6 In the initial state, the ring body 51 is located at the lower end limit position, the ring body 51 is inserted into the upper end of the through hole 411 to close the upper end of the through hole 411, and when the ring body 51 moves upward, the ring body 51 can be separated from the through hole 411 to open the upper end of the through hole 411.

[0033] like Figure 1 As shown in Figure 2, in the initial state, the rotating block 2 is at the lower limit position, the bottom of the support foot 23 is against the upper end of the fixed plate 4, the ring body 51 is inserted into the upper end of the through hole 411, and the upper end of the through hole 411 is closed. At this time, the flow rate of the cavity 6 is the largest. After the color paste is introduced, the color paste flows along the cavity 6 into the cavity 131. The rotating block 2 rotates so that the color paste flowing along the wall 24 tends to be thrown outward, so that the color paste in the cavity 6 is squeezed, which is conducive to the crushing effect of the mass solute in the color paste under pressure. At the same time, the rod body 3 drives the stirring plate 31 to rotate, and the stirring plate 31 stirs the color paste in the cavity 131.

[0034] When the color paste solution in the chamber 131 increases and cannot flow downward from the through hole 411, Figure 6 As shown, the rotating block 2 floats up, and the flow rate of the cavity 131 decreases. During the floating process of the rotating block 2, the ring body 51 moves upward, and the ring body 51 is separated from the through hole 411 to open the upper end of the through hole 411, and the color paste flows downward from the through hole 411. By delaying the opening of the through hole 411, the cavity 131 can store a certain amount of color paste to stir it. The color paste flow rate flowing in from cavity 16 is consistent with the color paste flow rate flowing out from through hole 411. When the color paste carried by the incoming color paste contains more agglomerated solutes, they will gather at through hole 411, causing blockage at the hole wall of through hole 411 and slowing down the color paste flow rate. At this time, the color paste solution in cavity 131 increases further, and the overall liquid level of the color paste solution rises, causing the rotating block 2 to float further upward, thereby further reducing the flow rate of cavity 16, thereby slowing down the flow rate of the color paste in cavity 16, and the distance between the wall 24 and the inner wall of the channel 2 12 is closer. Due to the rotation of the rotating block 2, the color paste is squeezed by the combined action of the wall 24 and the inner wall of the channel 2 12, which is beneficial to produce a better crushing effect of the agglomerated solutes in the color paste under pressure, making the color paste more delicate. The color paste feeding speed is slowed down by monitoring the distance between the wall 24 of the rotating block 2 and the channel 2 12. When the color paste flow rate flowing into the cavity 1 6 is consistent with the color paste flow rate flowing out of the through hole 411, the distance value is 5mm. When the distance is less than 2mm, the feeding speed is slowed down.

[0035] Due to the blockage at the wall of the through hole 411, the residence time of the color paste in the cavity 131 increases, which increases the stirring time, and then the color pastes carrying more lumpy solutes obtain a better stirring effect. As the fixing member 8 and the extension 52 clean the wall of the through hole 411, the through hole 411 is unblocked, and when the color paste passes through the through hole 411, it is cut by the fixing member 8, and the lumpy solutes in the color paste are cut into pieces, thereby improving the fineness of the color paste. As the color paste flows out of the through hole 411, the rotating block 2 slowly descends. When the spacing between the wall 24 of the rotating block 2 and the channel 2 12 is 5 mm, the feed resumes the initial speed. At this time, the extension 52 and the fixing member 8 are both located below the through hole 411.

[0036] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
