Description

Technical Field

[0001] This utility model relates to a mixer, specifically a cone-disc static pipe mixer. Background Technology

[0002] Currently, most of the mixers used in the industry are static mixers, which are mostly used in liquid-liquid mixing to speed up the mixing rate, reduce the dynamic stirring time, reduce the storage tank volume, and facilitate continuous production. Most of the mainstream static mixers with large pipe diameters and high flow rates are SK type mixers. Due to the large flow rate and large pipe diameter, the selected SK type mixers have fewer spiral layers, and the mixing effect is not very good.

[0003] In silica production, rapid adjustment and mixing are required when mixing low-viscosity liquids such as acids and mother liquors to achieve a homogeneous mixture. The SK-type mixers currently used in the industry have the following limitations:

[0004] Excessive flow rate will cause excessive loss of fluid dynamics in the inlet plate type;

[0005] Large-diameter, high-flow-rate pipes are suitable for fewer spiral layers, resulting in poor mixing performance.

[0006] When multiple liquids are fed, the pressure affects the flow rate and pressure of the main material and the auxiliary material. The injection points of the materials are uneven when they enter the pipeline, and the unevenness also exists when the spiral guides and mixes them. Utility Model Content

[0007] To address the shortcomings of the existing technology, this utility model provides an optimized design for a static mixer. This design addresses the need for rapid and uniform mixing of materials in the production of silica, particularly when mixing low-viscosity liquids (acid and mother liquor) under conditions of small storage tanks and continuous production. The resulting static mixer features low energy loss, good mixing effect, uniform injection, easy maintenance, and convenient use.

[0008] To achieve the above technical objectives, the present invention adopts the following technical solution: a conical disc static pipe mixer, comprising a coarse pipe and a fine pipe disposed in a pipe, the central axes of the coarse pipe and the fine pipe being symmetrical; a conical diverter is disposed inside the pipe, the conical diverter comprising a support frame and at least one ring disposed on the support frame, a plurality of conical parts being disposed within the ring area, the conical parts being fixed to the ring by connecting members, and the gaps formed between the conical parts being used for diverting materials.

[0009] The bottom surface of the cone is square.

[0010] The tapered device has a fixing hole / fixing groove, which is used to fix the connector.

[0011] The fixing hole / fixing groove is formed in the middle of the tapered object.

[0012] The connector is made of cable or stainless steel strip.

[0013] The total base area of ​​the cone is no more than 40% of the annular region.

[0014] The cones in adjacent layers are staggered.

[0015] The support frame employs multiple support rods, and the support rods are circumferentially and fixedly connected to multiple rings.

[0016] A central post is also provided at the center of the ring, and the connector can be fixed to the central post.

[0017] In summary, this utility model achieves the following technical effects:

[0018] This invention replaces the conventional single control method of controlling the flow rate through a regulating valve with a dual control method of pressure and flow rate when the material (liquid) enters the mixer. While ensuring the amount of material added, it also ensures the set pressure in the pipeline when the material flows into the mixer, so that the pressure of the two (or more) fluids entering the mixer is the same or close to the range value, so that the material forms a pressure impact and mixes first, resulting in better mixing effect; and eliminates the uneven injection caused by different pressures when the liquid enters the pipeline mixer.

[0019] This utility model adopts a square cone-shaped flow divider. Due to its pointed top and lower bottom, it splits the fluid in a bursting manner, resulting in less flow loss compared to spiral, corrugated, and crossbar methods. This reduces flow loss during high-splitting and mixing processes.

[0020] The material (liquid) of this invention has the characteristic of large flow rate. The liquid is divided and mixed by a four-sided square cone design. The number of times the liquid is mixed is more than that of a spiral design. A uniform effect is achieved through multiple division and mixing. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0031] Example:

[0032] Figure 1 It is a conical disc static pipeline mixer, including at least two feed pipes provided in the pipeline 1. A conical diverter 2 is provided inside the pipeline 1. The conical diverter 2 includes a support frame 22 and at least one ring 21 provided on the support frame 22. A plurality of cones 25 are provided in the area of ​​the ring 21. The cones 25 are fixed to the ring 21 by a connector 24. The gap formed between the cones 25 is used to divert materials.

[0033] In this embodiment, the feed pipe includes a coarse pipe 3 and a fine pipe 4, and the coarse pipe 3 and the fine pipe 4 are symmetrical about their central axes. The other end of the pipe 1 is provided with a discharge pipe 5.

[0034] This invention symmetrically arranges a coarse pipe 3 and a fine pipe 4, which are used to transport different materials. Simultaneously, the pressure and flow rate within the coarse pipe 3 and the fine pipe 4 are set to be consistent, meaning the difference is very small, and the materials in the two pipes are offset. Figure 1 (As shown by the two dashed arrows), due to the consistent pressure, the initial mixing occurs during the counter-current flow, enhancing the mixing effect. The multi-layered conical conical 25 sequentially divides the flow, ensuring thorough mixing.

[0035] Figure 2 This is a schematic diagram of a cone-shaped distributor. Figure 3 This is a schematic diagram of a single-layer splitter. Figure 4 yes Figure 3 From the top view, the bottom surface of the cone 25 is square, forming a structure with a pointed top and a square bottom. This structure provides a splitting effect for the fluid, resulting in less flow loss compared to spiral, corrugated, or crossbar designs. The cone 25 uses a single cone point and four bottom surfaces, effectively dividing a circle into multiple fluid surfaces. The flow directions formed by these surfaces converge at the bottom. The cone arrangement of the flow divider is adjusted to achieve multiple splitting and merging processes.

[0036] The bottom surface of the cone 25 is larger than the width of the connector 24 to prevent it from affecting the material diversion.

[0037] The conical device 25 has a fixing hole / slot for fixing the connector 24. The fixing part on the conical device 25 can use either a fixing hole or a fixing slot, as long as it can secure the connector 24. In this application, the connector 24 is made of cable or stainless steel strip. The cable can be tied around the fixing slot around the conical device or passed through the fixing hole of the conical device. In this embodiment, the connector 24 is made of steel strip, which provides greater support and prevents the conical device from tipping over or overturning under fluid impact.

[0038] The fixing hole / fixing groove is opened in the middle of the cone 25, which provides a better fixing effect.

[0039] The total bottom area of ​​the cone 25 is no more than 40% of the area of ​​the ring 21. In this embodiment, the cone bottom area accounts for 35%-40% of the inner area of ​​the pipe, which does not affect the flow rate and ensures thorough mixing.

[0040] The cones 25 of adjacent layers are staggered, with the cone of the next layer located in the gap of the cone of the previous layer. Material falling from the upper layer can be diverted again by the cone of the lower layer, and mixed thoroughly.

[0041] The support frame 22 uses multiple support rods, which are evenly distributed around the circumference and fixedly connected to multiple rings 21 to provide support. They can also be fixed to the inner wall of the pipe by bolts or other means, and can be removed as a whole for maintenance.

[0042] A central column 23 is also provided at the center of the ring 21, and the connector 24 can be fixed to the central column 23 to improve the support effect.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
