Abstract
Description
Technical Field
[0001] This utility model relates to the field of solid-liquid separation technology, specifically to a zirconium bead solid-liquid separation device for a sand mill. Background Technology
[0002] Currently, the solid-liquid separation in sand mills on the market uses a screen structure, which is a static separation method. For 200-nanometer-level products, φ0.1mm zirconium beads are required. The screen gap for φ0.1mm zirconium beads must be less than 0.05mm. This type of screen is particularly difficult to manufacture and is extremely prone to clogging in a short time. This leads to material blockage during sand mill operation, causing the equipment to malfunction. Furthermore, there is a lack of iterative design and a need to strengthen quality control. Utility Model Content
[0003] Therefore, the purpose of this invention is to provide a zirconium bead solid-liquid separation device for a sand mill. Through the cooperation of the zirconium bead solid-liquid separation component and the connecting locking component, a combination of axial and radial centrifugal separation spirals is used during operation. The axial spiral increases the centrifugal separation time of the fluid material, better adapting to the solid-liquid separation of high-viscosity fluids. Under centrifugal force, the radial spiral makes it easier to separate solids, such as zirconium beads and other materials, from the high-viscosity fluid.
[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: a zirconium bead solid-liquid separation device for a sand mill, comprising:
[0005] A zirconium bead solid-liquid separation assembly for a sand mill includes a three-phase asynchronous motor, a first pulley connected to the output end of the three-phase asynchronous motor, a belt wound around the first pulley, a second pulley connected to the belt, a discharge hollow shaft connected to the middle position of the second pulley, a bushing keyed to the discharge hollow shaft, an axial spiral separation block connected to the bushing, and a radial spiral separation block connected to the axial spiral separation block.
[0006] A connecting locking assembly includes a circular slot formed on the surface of the radial spiral separating block, a disc inserted into the circular slot, a hexagonal bolt with one end penetrating the disc and the other end fitting into the slot on the surface of the disc, a screw hole formed in the circular slot, and a first internal hexagonal screw penetrating the disc and connected to the screw hole.
[0007] As a preferred embodiment of the zirconium bead solid-liquid separation device for a sand mill described in this utility model, the outer wall of the discharge hollow shaft is fixed with a common flat key, and the inner side of the bushing is provided with a keyway, the common flat key and the keyway engaging with each other.
[0008] As a preferred embodiment of the zirconium bead solid-liquid separation device for a sand mill described in this utility model, the bottom surface of the bushing is provided with a hole, and the top end of the axial spiral separation block is fixed with a protrusion, the hole and the protrusion fitting together.
[0009] In a preferred embodiment of the zirconium bead solid-liquid separation device for a sand mill described in this utility model, the end of the hexagonal bolt is threadedly connected to the end of the discharge hollow shaft, and the axial spiral separation block and the radial spiral separation block are locked together by a connecting locking assembly.
[0010] As a preferred embodiment of the zirconium bead solid-liquid separation device for a sand mill according to the present invention, it further includes a product placement platform located on one side of the gripper assembly, and the product placement platform is used to place a heavy-duty product motor.
[0011] As a preferred embodiment of the zirconium bead solid-liquid separation device for a sand mill described in this utility model, it further includes a symmetrical double-helix separation component, which includes a first spiral separation block and a second spiral separation block that are locked and connected to the discharge hollow shaft.
[0012] As a preferred embodiment of the zirconium bead solid-liquid separation device for a sand mill described in this utility model, it further includes a combined assembly, which includes an inner groove on the bottom surface of the second spiral separation block, a first plate fitted with the inner groove, a threaded head with one end penetrating through the first plate and the other end fitting into the groove on the surface of the first plate, a second plate fitting into the first plate, and a second internal hexagon screw locking the first plate and the second plate together.
[0013] Compared with the prior art, the advantages of this utility model are:
[0014] By cooperating with the zirconium bead solid-liquid separation component and the connecting locking component of the sand mill, a combination of axial and radial centrifugal separation screws is achieved during use. The axial screw increases the centrifugal separation time of the fluid material, making it better suited for solid-liquid separation of high-viscosity fluids. Under centrifugal force, the radial screw makes it easier to separate solids, such as zirconium beads and other materials, from the high-viscosity fluid.
[0015] By using a symmetrical double-helix separation assembly, the separation efficiency is doubled compared to a single helix. The effective length of the radial helix groove is shorter, and the centrifugation time of the material is also shorter. This structure is well adapted to the solid-liquid separation of low-viscosity fluids. Under the action of centrifugal force, the radial helix makes it easier to separate solids, such as zirconium beads and materials, from the low-viscosity fluid.
[0016] In practical use, a three-phase asynchronous motor drives the first pulley to rotate at high speed, which in turn drives the second pulley to rotate via the belt. The discharge hollow shaft also rotates synchronously, driving the axial spiral separator and the radial spiral separator to rotate. The mixed material enters the separation device from the spiral groove of the radial spiral separator under the push of the diaphragm pump. The material with a small mass flows out of the device through the discharge hollow shaft, while the material with a large mass is pushed to the radial spiral separator by the action of the axial spiral separator. Finally, under the action of centrifugal force, it is thrown out of the separation device along the original path and enters the re-grinding chamber. In this way, when the fluid flows out of the separation device, all the heavy material that has been centrifuged to the inner diameter of the axial spiral separator is first pushed to the radial spiral separator by the axial spiral separator and then thrown out by the radial spiral separator. The combination of axial spiral and radial centrifugal separation spirals increases the centrifugal separation time of the fluid material by the axial spiral, which causes more material to be pushed to the radial spiral by the axial spiral during the process of flowing through the axial spiral, thus achieving efficient centrifugal separation.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0032] This invention provides a zirconium bead solid-liquid separation device for a sand mill. Through the cooperation of the zirconium bead solid-liquid separation component and the connecting locking component, a combination of axial and radial centrifugal separation spirals is used during operation. The axial spiral increases the centrifugal separation time of the fluid material, better adapting to the solid-liquid separation of high-viscosity fluids. Under centrifugal force, the radial spiral makes it easier to separate solids, such as zirconium beads and other materials, from the high-viscosity fluid.
[0033] Figures 1-6 The diagram shown is an overall structural schematic of one embodiment of the zirconium bead solid-liquid separation device for a sand mill according to this utility model. Please refer to [link / reference]. Figure 1-6The main structure of this embodiment includes: a zirconium bead solid-liquid separation assembly for a sand mill and a connecting and locking assembly.
[0034] A zirconium bead solid-liquid separation assembly for a sand mill includes a three-phase asynchronous motor 11, a first pulley 12 connected to the output end of the three-phase asynchronous motor 11, a belt 13 wound on the first pulley 12, a second pulley 14 connected to the belt 13, a discharge hollow shaft 15 connected to the middle position of the second pulley 14, a bushing 18 keyed to the discharge hollow shaft 15, an axial spiral separation block 16 connected to the bushing 18, and a radial spiral separation block 17 connected to the axial spiral separation block 16.
[0035] A standard flat key 110 is fixed to the outer wall of the discharge hollow shaft 15, and a keyway 111 is provided on the inner side of the bushing 18. The standard flat key 110 and the keyway 111 engage with each other. In use, the standard flat key 110 and the keyway 111 engage to limit the bushing 18 and ensure that the bushing 18 and the discharge hollow shaft 15 are linked.
[0036] The bottom surface of the bushing 18 is provided with a hole 181, and the top end of the axial spiral separating block 16 is fixed with a protrusion 19, and the hole 181 and the protrusion 19 fit together.
[0037] In use, the bushing 18 is joined together with the axial spiral separator 16, and they rotate simultaneously with the discharge hollow shaft 15.
[0038] The connecting locking assembly cooperates with the zirconium bead solid-liquid separation assembly of the sand mill to lock the axial spiral separation block 16 and the radial spiral separation block 17. Specifically, the connecting locking assembly includes a circular slot 21 opened on the surface of the radial spiral separation block 17, a disc 22 inserted into the circular slot 21, a hexagonal bolt 23 with one end penetrating the disc 22 and the other end fitting against the slot on the surface of the disc 22, a screw hole 25 opened in the circular slot 21, and a first internal hexagonal screw 24 penetrating the disc 22 and connected to the screw hole 25.
[0039] In practical use, the three-phase asynchronous motor 11 drives the first pulley 12 to rotate at high speed, which in turn drives the second pulley 14 to rotate via the belt 13. The discharge hollow shaft 15 also rotates synchronously, driving the axial spiral separator 16 and the radial spiral separator 17 to rotate. The mixed material enters the separation device from the spiral groove of the radial spiral separator 17 under the push of the diaphragm pump. The material with small mass flows out of the device through the discharge hollow shaft 15, while the material with large mass is pushed to the radial spiral separator 17 by the action of the axial spiral separator 16. Finally, under the action of centrifugal force, it is thrown out of the separation device along the original path and enters the re-grinding chamber. In this way, when the fluid flows out of the separation device, all the heavy material that has been centrifuged to the inner diameter of the axial spiral separator 16 is first pushed to the radial spiral separator 17 by the axial spiral separator 16 and then thrown out by the radial spiral separator 17. By using the combination of axial spiral and radial centrifugal separation spirals, the axial spiral increases the centrifugal separation time of the fluid material, resulting in more material being pushed to the radial spiral by the axial spiral during the flow of the fluid material, thus achieving efficient centrifugal separation.
[0040] For further details, please refer to Figures 7-9 By using a symmetrical double-helix separation component, the separation efficiency is doubled compared to a single helix. The effective length of the radial helix groove is shorter, and the centrifugation time of the material is also shorter. This structure is well adapted to the solid-liquid separation of low-viscosity fluids. Under the action of centrifugal force, the radial helix makes it easier to separate solids, such as zirconium beads and materials, from the low-viscosity fluid.
[0041] Specifically, it also includes a symmetrical double-helix separation assembly, which includes a first spiral separation block 31 and a second spiral separation block 32 that are locked and connected to the discharge hollow shaft 15.
[0042] It also includes a joint component, which includes an inner groove 41 opened on the bottom surface of the second spiral separating block 32, a first plate 42 fitted with the inner groove 41, a threaded head 43 with one end penetrating through the first plate 42 and the other end fitting into the groove on the surface of the first plate 42, a second plate 44 fitting into the first plate 42, and a second internal hexagon screw 45 locking the first plate 42 and the second plate 44 together.
[0043] In practical use, the same working principle applies. The discharge hollow shaft 15 drives the first spiral separation block 31 and the second spiral separation block 32 to rotate. The mixed material enters the separation device through the spiral grooves of the first spiral separation block 31 and the second spiral separation block 32 under the push of the diaphragm pump. The material with small mass flows out of the equipment through the discharge hollow shaft 15, while the material with large mass is thrown out of the separation block along the radial spiral under the action of the centrifugal force provided by the double spiral. This allows the large mass objects, such as the material and zirconium beads, to re-enter the grinding chamber, thereby achieving the separation of the material and the zirconium beads. In this way, the effective length of the radial spiral groove is shorter, and the centrifugation time of the material is also shorter. This structure is well adapted to the solid-liquid separation of low viscosity fluids. The use of double spirals increases the separation efficiency by several times compared to single spirals.
[0044] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
