Description

Technical Field

[0001] This utility model relates to the field of extraction and mixing equipment, and in particular to a mixing and enhancing high-efficiency extraction device. Background Technology

[0002] Against the backdrop of the global advocacy for green and low-carbon development, and the active promotion of the realization of "dual carbon" goals, industrial enterprises, as major energy consumers, face the urgent task of energy conservation and emission reduction.

[0003] Currently, extraction and mixing processes consume a lot of energy, have low energy efficiency, and involve energy waste in some production stages. This not only increases production costs but also contradicts the national policy of green development. To enhance the company's market competitiveness, respond to national energy conservation and emission reduction policies, and reduce energy consumption and production costs, this energy-saving technological upgrading project is being undertaken.

[0004] Currently used vertical shaft pumps have problems such as low mixing efficiency, large energy loss, and insufficient operational stability in solid-liquid mixing scenarios due to unreasonable impeller flow channel design. Specifically, these problems include uneven solid dispersion, poor head-flow matching, and significant efficiency decay after long-term operation. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-efficiency extraction device for mixing and lifting, which aims to improve the problems of uneven solid phase dispersion, poor head and flow rate matching, and significant efficiency decay after long-term operation in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mixing and lifting high-efficiency extraction device, comprising a cylinder, a stirring mechanism installed at the upper part of the cylinder, a static mixing component installed at the lower part of the cylinder, a guide cylinder installed inside the cylinder, a sieve plate provided at the upper part of the static mixing component, the sieve plate being fixedly connected to the inner wall of the cylinder, a motor being fixedly connected to the top of the cylinder, a casing shaft being fixedly connected to the output end of the motor, the casing shaft penetrating and rotatably connected to the cylinder, a secondary impeller being fixedly connected to the middle part of the outer wall of the casing shaft, a primary impeller being fixedly connected to the lower part of the outer wall of the casing shaft, secondary blades being fixedly connected to the outer wall of the secondary impeller, and primary blades being fixedly connected to the outer wall of the primary impeller.

[0011] As a further description of the above technical solution:

[0013] As a further description of the above technical solution:

[0014] The static mixing sheet is a twisted sheet, and multiple static mixing sheets are arranged in an alternating manner.

[0015] As a further description of the above technical solution:

[0017] As a further description of the above technical solution:

[0018] The sieve plate has fine sieve holes evenly distributed in the middle.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, the staged stirring of the first-stage impeller and the second-stage impeller, combined with the static mixing blades with alternating twisting, achieves efficient dispersion and full contact of materials, solving the problem of uneven solid-phase dispersion and improving extraction efficiency. At the same time, through the rational design of the impeller flow channel and blade structure, the asymmetric curved blades reduce impact and wake loss, reduce efficiency decay caused by power waste, and can also adapt to actual working conditions to improve fluid driving force. The number of second-stage blades can be adapted to the diameter of the first-stage impeller as needed to further enhance fluid conveying capacity, taking into account both head and flow rate improvement, thereby reducing energy loss and mixing energy consumption.

[0021] 2. In this utility model, by setting the guide tube, the fluid can be forced to flow strictly along the set path to prevent short circuits and ensure that all fluids are fully stirred through the high shear zone. The porous sieve plate can shear larger droplets and bubbles into smaller ones, increase the mass transfer area, and make the upward-flowing fluid more evenly distributed on the cross-section, which greatly improves the mass transfer efficiency and mixing uniformity.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-3 This utility model provides an embodiment of a high-efficiency mixing and extraction device, comprising a cylinder 1 for carrying materials and coordinating material mixing and extraction operations. A stirring mechanism 2 is installed on the upper part of the cylinder 1 to facilitate gradient stirring of the materials. A static mixing component 3 is installed on the lower part of the cylinder 1 to facilitate initial mixing of the materials. The two components work together to ensure mixing and extraction efficiency. A guide tube 4 is installed inside the cylinder 1, which enhances the axial flow from bottom to top, preventing short-circuiting and turbulence in the stirring zone. It allows the fluid to flow obliquely from the impeller area to the overflow port 11, ensuring stable flow along a set path, increasing the fluid delivery volume (flow rate) per unit time, and simultaneously enhancing the axial thrust (head) of the fluid, greatly improving mixing efficiency and extraction mass transfer rate. The guide tube 4 is fitted onto the first-stage impeller 24 and the second-stage impeller 25. The static mixing component 3 is equipped with a sieve plate 5 on its upper part, which can be increased according to actual conditions. The static mixing component 3 and the stirring mechanism 2 work together to achieve preliminary mixing and gradient stirring of materials. The two work together to improve the mixing and extraction efficiency and avoid the decline in mass transfer efficiency due to insufficient mixing. The sieve plate 5 is fixedly connected to the inner wall of the cylinder 1. The upper and lower parts of the outer wall of the guide tube 4 are fixedly connected with multiple support plates 41. The support plates 41 are fixedly connected to the inner wall of the cylinder 1. The middle part of the sieve plate 5 is evenly distributed with fine sieve holes 51, which can shear larger droplets and bubbles into smaller ones, increase the mass transfer area, and make the upward flowing fluid more evenly distributed in the cross section. If multiple sieve plates 5 are provided, the aperture of the sieve holes 51 can be increased or decreased according to actual conditions to achieve step-by-step crushing.

[0029] Furthermore, a motor 21 is fixedly connected to the top of the cylinder 1 to provide power output. A casing 22 is fixedly connected to the output end of the motor 21. The casing 22 passes through and is rotatably connected to the cylinder 1. A secondary impeller 23 is fixedly connected to the middle of the outer wall of the casing 22. A primary impeller 24 is fixedly connected to the lower part of the outer wall of the casing 22. Secondary blades 231 are fixedly connected to the outer wall of the secondary impeller 23. The number of blades can be increased according to the diameter of the primary impeller 24. Primary blades 241 are fixedly connected to the outer wall of the primary impeller 24. The blades are designed with an asymmetric curved surface. The asymmetric curved surface blades reduce impact and wake loss, reduce efficiency decay caused by power waste, and make the fluid velocity distribution more in line with the actual working conditions. The asymmetric curved surface blades fit the actual working conditions and improve the fluid driving force. The number of secondary blades 231 can be adapted to the diameter of the primary impeller 24 as needed to further enhance the fluid conveying capacity and take into account both head and flow rate improvement.

[0030] Furthermore, an overflow port 11 is provided on the upper front side of the cylinder 1, and the overflow port 11 is connected to an overflow cylinder 12 for orderly guiding materials and avoiding splashing.

[0031] Specifically, the static mixing component 3 includes a guide plate 31, which serves as a support and guide. The guide plate 31 is fixedly connected to the lower part of the inner wall of the cylinder 1. The top of the guide plate 31 is fixedly connected to multiple static mixing plates 32. The static mixing plates 32 are twisted plates, and the multiple static mixing plates 32 are staggered, which can effectively disrupt the material flow trajectory and improve the solid-liquid contact. The staggered twisting of the static mixing plates 32 disrupts the material trajectory and provides initial power for fluid flow.

[0032] Working principle: The material to be processed first enters the lower area of ​​the cylinder 1 and flows through the static mixer 3. The guide plate 31 plays a supporting and guiding role, guiding the material to be evenly distributed and flow to multiple staggered swirl-type static mixing plates 32. The static mixing plates 32 disrupt the initial flow state of the material through a special structure, break the solid-liquid stratification phenomenon, and initially improve the sufficient contact between the two phases, laying the foundation for subsequent deep mixing.

[0033] After static pretreatment, the material flows upward, passes through the sieve holes 51 on the sieve plate 5, and then enters the working area of ​​the stirring mechanism 2 at the top of the cylinder 1. After the motor 21 starts, it outputs power and transmits it stably to the secondary impeller 23 and the primary impeller 24 through the shaft 22, driving the two impellers to rotate synchronously. The primary blade 241 adopts an asymmetrical curved surface design, which makes the fluid velocity distribution match the actual working conditions when rotating, reduces energy loss, and further disperses the material. The primary blade 241 and the secondary impeller 23 form a gradient stirring effect, while the guide tube 4 can deepen the mixing degree of the material.

[0034] After being deeply mixed by two impellers, the material continues to flow upward and completes the extraction reaction inside the device. The material that is finally formed in a stable flow state will be discharged in an orderly manner through the overflow port 11 on the upper front side of the cylinder 1. The overflow cylinder 12 avoids material splashing and ensures a clean working environment and efficient material recovery.

[0035] Additionally, it should be noted that components not described in detail in this article are existing technologies.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
