[0001] The application belongs to the technical field of material processing equipment, and particularly relates to a closed adjustable dynamic and static high-shear homogenization and pressurization mixer. BACKGROUND

[0002] The mixer is a device for mixing two or more different media, and generally has the functions of shearing and emulsifying the media. In the fields of oil and gas exploitation, mining, chemical industry and food, the mixer is used, and the homogenization and mixing effect will directly affect the material quality and production efficiency. The traditional mixer generally comprises an inlet, a pump shell and an impeller, and the impeller is generally of a closed structure. The media is mixed by high-speed rotation of the impeller, and is discharged under the action of centrifugal force. However, the prior art has the problem of insufficient shearing of the media, and it is difficult to mix high-viscosity, high-concentration or extremely fine materials. Secondly, the existing mixer needs to replace corresponding parts for different materials, and is generally equipped with multiple stators and impellers, and has many additional components. Moreover, the structure of the existing mixer is redundant, and another pressurization device is often required, and the mixer cannot realize pressurization of the media alone. SUMMARY

The transmission device comprises a rotating transmission shaft, and the transmission shaft passes through the modular pump shell to drive the rotation of the impeller assembly.

[0005] The basic principle of the adjustable closed dynamic and static high shear force homogenization and pressurization mixer is that the multiple disc arrangement of the impeller assembly provides a larger mixing space and more blades, which can enhance the homogenization and pressurization of the multiphase medium, the increase of the through-flow circular hole is also beneficial to the flow of the multiphase medium in the impeller assembly, and the connecting column can also ensure that the impeller assembly has sufficient strength, the turbulence block can generate stronger turbulence in the impeller to strengthen the mixing, and the inclined blade surface can guide the flow.

[0006] When the entire mixer is used, the impeller assembly rotates at high speed under the drive of the transmission device, the negative pressure generated by the rotation of the impeller assembly causes the multiphase medium to flow into the entire mixer along the inlet assembly, the multiphase medium is discharged radially along the impeller assembly under the disturbance of the blades, and the multiphase medium flows through the second mixing chamber from the first mixing chamber in turn through the turbulence block, the connecting column and the impeller shearing block, when the multiphase medium passes through the two mixing chambers in turn, the turbulence block strengthens the turbulence in the impeller assembly, and the double-layer design of the impeller assembly is also beneficial to the pressurization of the multiphase medium, under the action of the strong rotation and pressurization, the multiphase medium is gradually sheared, broken and homogenized to meet the refinement requirement, and then the multiphase medium is discharged along the outlet assembly of the side wall of the modular pump shell under the action of the centrifugal force. The problem that the existing mixer cannot homogenize and pressurize the material is solved.

[0007] Further, the adjustable closed dynamic and static high shear force homogenizing and pressurizing mixer further comprises a stator assembly arranged inside the modular pump shell, the stator assembly comprises a plurality of grid bars arranged in a ring shape and uniformly spaced around the axis of the modular pump shell, both ends of each grid bar are provided with a grid bar cylinder for connecting with both sides of the modular pump shell; each grid bar is provided with two axially arranged threaded holes, and a double-headed stud is arranged in each threaded hole; the top end of each double-headed stud is connected with a guide vane, and the bottom end is connected with a T-shaped shear block; there is a gap between the two guide vanes on each grid bar, and there is also a gap between the two guide vanes and the two sides of the modular pump shell; in the adjacent two wheel discs, the outer wall side of the two impeller shear blocks, the middle part of the two blades and the connecting column are enclosed to form a T-shaped shear groove; the T-shaped shear block and the T-shaped shear groove are in one-to-one matching relationship, and a T-shaped shear block is arranged in each T-shaped shear groove.

[0008] The working principle of the mixer provided with the stator assembly is as follows: the multiphase medium flows into the mixer along the inlet assembly, the multiphase medium is discharged radially along the impeller assembly under the disturbance of the blade, and then passes through the spoiler, the connecting column and the T-shaped shear block, wherein the multiphase medium generates a strong shear effect with the T-shaped shear block, and then flows through the second mixing chamber, at this time, the multiphase medium generates a dynamic and static shear effect between the stator assembly and the impeller assembly, and the multiphase medium flowing through the stator assembly is discharged along the outlet assembly of the side wall of the modular pump shell under the action of centrifugal force. The strong shear effect between the T-shaped shear block and the T-shaped shear groove can make the multiphase medium be fully sheared and broken and mixed.

[0009] Further, the modular pump shell is in a hollow cylindrical structure arranged horizontally, and a left end cover and a right end cover are detachably arranged on the two sides of the modular pump shell, respectively, a flow-in round hole is arranged at the center of the left end cover, and the inlet assembly comprises an inlet pipe in communication with the flow-in round hole; an outflow port is arranged on the side wall of the modular pump shell, the outflow port is arranged along the tangential direction of the circumference of the modular pump shell, the outlet assembly comprises an outlet pipe in communication with the outflow port, and a flange plate is connected to the end of the inlet pipe and the outlet pipe.

The flange plate is arranged to facilitate the connection of the inlet pipe and the outlet pipe with other pipelines, and can be installed at any desired position.

[0011] Further, the diameter of the through-flow round hole is greater than the diameter of the inlet round hole.

[0012] Further, a gap is arranged between the left disc and the left end cover. The gap has the beneficial effect of facilitating the entry of the multiphase medium into the impeller assembly.

[0013] Further, the left end cover and the right end cover are each provided with a number of mounting holes in the circumferential direction, the number of which is the same as that of the grid bars. Each grid bar is matched with two mounting holes, and the grid bar cylinders at the two ends of each grid bar are arranged in the corresponding mounting holes of the left end cover and the right end cover. A plurality of connecting holes are arranged at the outer edges of the left end cover and the right end cover, and the left end cover and the right end cover are fixed to the two sides of the modular pump shell through screws passing through the connecting holes.

[0014] The mounting holes in the left end cover and the right end cover have the beneficial effect of fixing the grid bars. The left end cover and the right end cover are fixed to the two sides of the modular pump shell, which can make the mixer form a whole and reduce the risk of leakage of the multiphase medium.

[0015] Further, the right disc is provided with an impeller hub at the center, the circumferential inner wall of the impeller hub is provided with an impeller hub key groove in the axial direction, and the circumferential outer wall of the impeller hub is provided with a radial bearing.

The center of the two side surfaces of the right end cover is provided with a sealing ring mounting groove, and the sealing ring mounting groove is coaxially arranged with the bearing mounting hole. A sealing ring is arranged in each sealing ring mounting groove, and the inner ring of each sealing ring is in tight contact with the circumferential outer wall of the impeller hub. The transmission shaft is connected with the impeller hub through the connection of the connecting key and the impeller hub key groove.

[0016] The above arrangement has the beneficial effect of ensuring that the power of the transmission device is transmitted to the impeller assembly. The arrangement of the radial bearing and the sealing ring ensures that the impeller assembly rotates and the mixed medium does not leak along the impeller hub.

[0017] Further, an adjustment ring mounting groove is arranged on the right side surface of the right end cover, and a grid bar rotation adjustment ring is rotatably arranged in the adjustment ring mounting groove.

A right end cover auxiliary plate is arranged on the right side of the right end cover, and the right end cover auxiliary plate is a three-quarter circular ring and is pressed on the outer edge of the grid bar rotation adjustment ring. The grid bar cylinders at the right ends of the grid bars each protrude a certain length from the right end cover, and a gear is fixedly arranged on each grid bar cylinder, which is engaged with the teeth of the inner gear.

[0018] The beneficial effect of the above arrangement is that when the adjusting handle is rotated, the rotating power is transmitted to the gear through the inner gear, so that the grid strip drives the T-shaped shearing block to be placed in the impeller assembly, the grid strip or the modular pump shell, that is, the T-shaped shearing block is placed in the T-shaped shearing groove to play a shearing crushing effect when the mixing medium needs to be finely divided, and is placed in the stator assembly or the modular pump shell to play a turbulence effect on the mixing medium when it is not needed.

[0019] Further, a gear block is arranged on the right side surface of the right end cover, and three grooves for cooperating with the adjusting handle are arranged on the gear block.

[0021] Further, the end of each guide vane is bent to one side, and the bending direction of the guide vane is consistent with the tangential direction of the circumference of the rotation of the impeller assembly.

[0022] The beneficial effect of the above arrangement is that the guide vane plays a guide effect, so that the flow of the multiphase medium is smoother.

The adjustable closed dynamic and static high shear force homogenization-pressurization mixer provided by the present application can make the uniformity and fragmentation of the mixed multiphase medium higher, the turbulence block in the impeller assembly can make the multiphase medium generate stronger turbulence in the first mixing cavity, the dynamic-static strong shear effect generated by the cooperation of the T-shaped shearing block and the T-shaped shearing groove increases the shearing, fragmentation and mixing space of the multiphase medium, and improves the homogenization and refinement degree of the multiphase medium. At the same time, whether to install the T-shaped shearing block and the guide vane can be selected according to actual needs, or the T-shaped shearing block can be adjusted to be placed in different working positions to adapt to actual needs, so that independent adjustment and adaptation are realized, the accessories are simplified, and frequent assembly and disassembly are avoided.

[0039] First embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the application provides a adjustable closed dynamic and static high shear force homogenization-pressurization mixer, comprising a modular pump shell 1 and a transmission device; the inside of the modular pump shell 1 is provided with an impeller assembly 7; the two sides of the modular pump shell 1 are respectively provided with an inlet assembly 2 and an outlet assembly 3.

[0040] The impeller assembly 7 comprises a left disc 701, a middle disc 702 and a right disc 703 arranged in the axial direction of the modular pump shell 1 from left to right in sequence, the center of the left disc 701 is provided with an inlet circular hole 712, the center of the middle disc 702 is provided with a through-flow circular hole 713, and the adjacent two discs are fixed through a plurality of annularly spaced connecting columns 704; specifically, the diameter of the through-flow circular hole 713 is greater than the diameter of the inlet circular hole 712. The beneficial effect of such arrangement is that the increase of the through-flow circular hole 713 is also conducive to the flow of the multi-phase medium in the impeller assembly 7, and at the same time, the connecting column 704 can also ensure that the impeller assembly 7 has sufficient strength, the turbulence block 706 makes the impeller inside generate stronger turbulence, and the mixing is strengthened.

[0041] The space between the adjacent two discs is a first mixing cavity 16; the space between the outer edges of the three discs and the modular pump shell 1 is a second mixing cavity 17; The side surfaces of the left disc 701 right side, the right disc 703 left side and the middle disc 702 two sides are all provided with a plurality of blades 705 arrayed in the circumferential direction, the plurality of blades 705 on the adjacent two discs are in one-to-one correspondence, a gap is arranged between the two corresponding blades 705 on the adjacent two discs, and a connecting column 704 is arranged between every two blades 705, the two ends of the connecting column 704 are connected with the middle parts of the two corresponding blades 705 on the adjacent two discs respectively; two layers of turbulence blocks 706 are arranged on the side wall of each blade 705 close to the circumferential direction, and a rectangular structure impeller shear block 708 is arranged on the side wall away from the circumferential direction; an inclined blade surface 707 is arranged at one end of each blade 705 close to the circumferential direction, and the normal direction of the inclined blade surface 707 forms an acute angle with the rotation axial direction of the impeller assembly 7.

[0042] The transmission device comprises a rotating transmission shaft, and the transmission shaft drives the impeller assembly 7 to rotate through the modular pump shell 1.

[0043] The basic principle of the adjustable closed dynamic and static high shear force homogenization-pressurization mixer is that the multi-disc arrangement of the impeller assembly 7 makes the impeller assembly 7 have a larger mixing space and more blades 705, which can enhance the homogenization and pressurization of the multi-phase medium, the increase of the through-flow circular hole 713 is also conducive to the flow of the multi-phase medium in the impeller assembly 7, at the same time, the connecting column 704 can also ensure that the impeller assembly 7 has sufficient strength, the turbulence block 706 makes the impeller inside generate stronger turbulence, and the mixing is strengthened.

The multiphase medium is discharged radially along the impeller assembly 7 under the disturbance of the blades 705, and then flows through the second mixing chamber 17 from the first mixing chamber 16 in sequence through the spoiler 706, the connecting column 704 and the impeller shear block 708.

Under the action of strong rotation and pressurization, the multiphase medium is gradually sheared, broken and homogenized to meet the refinement requirements, and then discharged along the outlet assembly 3 of the side wall of the modular pump shell 1 under the action of centrifugal force. The problem of insufficient homogeneity of the material and inability to pressurize and mix of the existing mixer is solved.

[0045] In the second embodiment, the second embodiment of the present application provides an adjustable closed dynamic and static high shear force homogenization-pressurization mixer.
