Description

Technical Field

[0001] The utility model relates to the technical field of mixer devices, in particular to an SK type static mixer device. Background Art

[0002] SK type static mixer, which is composed of spiral plates twisted 180° or 270°. When installed into the tube shell, the adjacent spiral plates are left-handed and right-handed respectively. It uses the mixing unit body fixed in the tube to change the flow state of the fluid in the tube. It is only suitable for mixing processes with low requirements and unit operation processes related to mixing. It can also be used to enhance heat transfer;

[0003] In combination with the above content, it should be explained that: during the use of the traditional SK type static mixer, a simple and smooth spiral plate (left-handed and right-handed) structure is usually used to change the flow direction of the fluid, which has a limited degree of interference with the fluid flow process, thereby causing an unsatisfactory mixing effect of the fluid. At the same time, the traditional SK type static mixer has a single flow axis, which leads to the need to increase the flow distance and mixing time during the mixing of different fluids, or to perform multiple reciprocating treatments on the same batch of fluids, which is time-consuming, labor-intensive, and inefficient;

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0005] The utility model aims to provide an SK type static mixer device, which is used in conjunction with an inner cylinder and a chamber cylinder, and utilizes the right-hand and left-hand racks with concave-convex structures in the chamber cylinder to guide the multi-axial and multi-dimensional mixed and disturbed flow of the fluid, thereby accelerating the mixing between the fluids, and utilizing the overflow port to squeeze and inject the initially disturbed mixed fluid into the overflow cavity, thereby promoting the fluid to be pressurized and ejected from bottom to top, which can not only realize the initial disturbed mixing of multiple streams of the fluid, but also reversely pressurize and push it, and combine the dead weight of the fluid, the limited extrusion of the cavity space and the continuous injection pressure of the fluid to recoil, convey and mix the fluid, effectively change the flow state of the fluid, increase the mass transfer and heat transfer effect of the fluid, and solve the problems raised.

[0006] The purpose of the utility model can be achieved by the following technical solutions: an SK type static mixer device, comprising an inner cylinder, a cross-type partition frame is arranged inside the inner cylinder, a chamber dividing cylinder is arranged in the compartment between the cross-type partition frame and the inner cylinder, a right-handed frame is arranged inside the chamber dividing cylinder, and a left-handed frame is connected to the bottom of the right-handed frame;

[0007] An outer cylinder is arranged on the outer periphery of the inner cylinder, a spiral ring sheet is arranged on the cylinder wall between the inner cylinder and the outer cylinder, and a gathering cone is arranged at the bottom of the outer cylinder.

[0013] Beneficial effects of the utility model:

[0014] (1) The utility model uses the inner cylinder and the chamber cylinder to match each other, and uses the right-hand and left-hand racks with concave-convex structures in the chamber cylinder to guide the multi-axial and multi-dimensional mixed and disturbed flow of the fluid, thereby accelerating the mixing between the fluids, and uses the overflow port to squeeze and inject the initially disturbed mixed fluid into the overflow cavity, thereby promoting the fluid to surge from bottom to top in a pressurized manner. It can not only achieve the initial disturbance mixing of the multi-stream flow of the fluid, promote the preliminary mixing and detailed treatment of the fluid, but also reversely pressurize and push it. Combined with the dead weight of the fluid, the limited extrusion of the cavity space and the continuous injection pressure of the fluid, the fluid is recoiled, transported and mixed, effectively changing the flow state of the fluid, increasing the flow distance in a small space, increasing the mass transfer and heat transfer effect of the fluid, and improving the mixing treatment efficiency of the fluid;

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

[0024] Embodiment 1:

[0025] This embodiment is used to solve the problem that during use, a traditional SK type static mixer usually uses a simple and smooth left-handed and right-handed spiral plate structure to change the flow direction of the fluid, which has a limited degree of interference with the fluid flow process, thereby causing an unsatisfactory mixing effect on the fluid.

[0026] See also Figure 1 - Figure 4 As shown, this embodiment is an SK type static mixer device, comprising an inner cylinder 1, a cross partition frame 101 is arranged inside the inner cylinder 1, a chamber cylinder 2 is arranged in the compartment between the cross partition frame 101 and the inner cylinder 1, a right-handed frame 201 is arranged inside the chamber cylinder 2, a left-handed frame 205 is connected to the bottom of the right-handed frame 201, and an external device is connected to the top and bottom of the SK type device to promote the top of the outer cylinder 4 to be sealed, wherein the injection port of the external device is connected to the top of the multi-component chamber cylinder 2;

[0027] A sealing pad 103 connected to the bottom of the dividing chamber cylinder 2 is arranged at the bottom of the inner cylinder 1, a plurality of overflow chambers 102 are arranged between the cross partition 101 and the dividing chamber cylinder 2, an overflow channel connected to the spiral ring sheet 3 is arranged at the top of the overflow chamber 102, and a plurality of detachable interference columns are arranged inside the overflow chamber 102. The demixing fluid entering the overflow chamber 102 contacts and collides with the inner cylinder 1 and the cross partition 101, and changes its flow direction due to the size of the overflow chamber 102. After the demixing fluids are piled up on each other, they rise along the overflow chamber 102. In this process, they are affected by the interference columns, causing the demixing fluids to be mixed twice in the overflow chamber 102 to obtain two mixed fluids. After the two mixed fluids fill the overflow chamber 102, they enter the overflow channel and penetrate into between the inner cylinder 1 and the outer cylinder 4 along the overflow channel.

[0028] A plurality of overflow ports 202 are arranged at the bottom of the cavity cylinder 2, and external equipment injects fluid along the injection port and the top of the cavity cylinder 2. Different fluids are mixed and enter the single-component cavity cylinder 2, and the different fluids flow along the gap between the surface of the right-handed frame 201 and the left-handed frame 205 and the cavity cylinder 2. Affected by the protrusions 203 and the grooves 204, the different fluids are prompted to send flow trajectories and fluid position interference guides during the flow along the gap, so that the fluids are initially dispersed and mixed in the cavity cylinder 2 to obtain a demixing fluid. The demixing fluid is pushed and accumulated at the bottom of the cavity cylinder 2 by its own weight and the subsequent injection of fluid. Under the pushing of various mixing pressures, the demixing fluid is ejected and overflowed into the overflow chamber 102 along the overflow port 202. The surfaces of the right-handed frame 201 and the left-handed frame 205 are both provided with a plurality of protrusions 203 and grooves 204.

[0029] Embodiment 2:

[0030] This embodiment is used to solve the problem that the traditional SK type static mixer has a single flow axis, which leads to the need to increase the flow distance and mixing time during the mixing of different fluids, or to perform multiple reciprocating treatments on the same batch of fluids, which is time-consuming, labor-intensive, inefficient, and causes uneven mixing. It also has a significant amplification effect, and the droplets can only be dispersed to a particle size of ≥10μm during the emulsification process, and the operational stability is poor, so it can only be used for general mixing processes.

[0031] See also Figure 1 , Figure 5 As shown, an SK type static mixer device of this embodiment includes an outer cylinder 4 arranged on the outer periphery of an inner cylinder 1, a spiral ring sheet 3 is arranged on the cylinder wall between the inner cylinder 1 and the outer cylinder 4, and a gathering cone 5 is arranged at the bottom of the outer cylinder 4;

[0032] The surface of the spiral ring sheet 3 is provided with multiple groups of convex columns 301. The cross sections on both sides of the spiral ring sheet 3 are sealed and connected with the cylinder walls of the inner cylinder 1 and the outer cylinder 4 respectively. The two mixed fluids fall from the top of the inner cylinder 1 to the surface of the spiral ring sheet 3. Under the condition of continuous injection, the injected two mixed fluids are pushed to flow downstream along the surface of the spiral ring sheet 3. In this process, the two mixed fluids are disturbed and blocked by the convex columns 301, causing the two mixed fluids to be separated and mixed with each other, and affected by the spiral chamber formed by the spiral ring sheet 3, the outer cylinder 4 and the inner cylinder 1, causing the two mixed fluids close to the outer cylinder 4 to be pushed and rolled upward, and stirring and mixing between the fluids are generated again to obtain a three mixed fluid;

[0033] A cone ring 501 connected to the bottom of the outer cylinder 4 is arranged on the top of the aggregate cone 5. The bottom of the aggregate cone 5 is designed in a circular ring shape. When the three-mixed fluid passes through the bottom of the spiral ring sheet 3, it falls into the cone ring 501. Affected by the inclination angle of the inner wall of the cone ring 501, the three-mixed fluid flows downwardly until it is collected in the circular ring at the bottom of the aggregate cone 5, and then flows to the equipment installed at the bottom of the SK type static mixer. During the emulsification process, the droplets can be dispersed to a particle size of ≥5μm, the operation stability is good, and the problem of difficult uniform mixing of multiple liquids is solved.

[0034] Combining Example 1 and Example 2, it can not only achieve preliminary mixing of multiple streams of the fluid and promote the preliminary mixing and delicate processing of the fluid, but also reverse pressurize and push it. Combining the dead weight of the fluid, the limited extrusion of the cavity space and the continuous injection pressure of the fluid to recoil, convey and mix the fluid, effectively change the flow state of the fluid, increase the flow distance in a small space, increase the mass transfer and heat transfer effect of the fluid, and improve the mixing and processing efficiency of the fluid. The spiral ring sheet 3 forms a spiral conveying channel between the inner cylinder 1 and the outer cylinder 4, which helps the fluid to contact with the convex column 301 during the flow under the dead weight and the continuous pushing pressure of the subsequent injection, further promoting good dispersion and sufficient mixing between different fluids. The droplets can be dispersed to a particle size of ≤5μm during the emulsification process, with good operational stability, solving the problem of difficult uniform mixing of multiple liquids.
