A static mixing tubular reaction device

Abstract

This utility model relates to the field of mixing equipment technology, specifically to a static mixing tubular reaction device, comprising: two support bases and a conveying mechanism. In this utility model, a conveying mechanism is provided on the reactor body, and the heat exchange medium is brought into contact with the conveying mechanism via the reactor body, the heat exchange medium inlet pipe, and the heat exchange medium outlet pipe. This allows the temperature of the conveying mechanism to be adjusted using the flowing heat exchange medium, thereby ensuring the reaction effect of the conveying mechanism. Furthermore, the feed pipe facilitates the conveying of materials into the corresponding conveying pipe. Mixing core body one and mixing core body two divide the material into multiple streams, with the flow velocity increasing in the middle of the material conveying pipe and decreasing at both ends, breaking the stable state of material flow. This allows the materials to collide and shear at different speeds, enhancing the turbulence intensity. The increased turbulence generates more eddies and shear forces, thus ensuring thorough mixing of the materials.

Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically a static mixing tubular reaction device. Background Technology

[0002] Polyurethane-modified epoxy toughening agents are compounds that modify epoxy resins with polyurethane, primarily used to improve the toughness and impact resistance of epoxy resins. The production of polyurethane-modified epoxy toughening agents generally requires the mixing and reaction of multiple materials. Existing mixing equipment used in the production of polyurethane-modified epoxy toughening agents typically employs a reactor, utilizing a stirring structure on the reactor to mix and stir the various materials to induce a reaction. However, the unidirectional rotation of the stirring structure on the reactor results in the materials flowing in an orderly manner during the mixing process, leading to poor mixing efficiency and affecting the reaction rate and overall effect of the reaction. Utility Model Content

[0003] The purpose of this invention is to provide a static mixing tubular reaction device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A static mixing tubular reaction apparatus, comprising:

[0006] Two support bases are provided, and a reactor body is fixedly fitted onto the two support bases. Multiple round holes are provided at both ends of the reactor body. A heat exchange medium inlet pipe and a heat exchange medium outlet pipe are connected and fixed to the reactor body.

[0007] A conveying mechanism, installed on the reactor body, is used for conveying and mixing materials.

[0008] Furthermore, the conveying mechanism includes:

[0009] Multiple conveying pipes, with both ends of the multiple conveying pipes respectively fixed to the inner sidewall of the corresponding circular hole, each end of the conveying pipe having a connecting groove, and the inner sidewall of the connecting groove having multiple slots, and the inside of the conveying pipe having a mixing component.

[0010] A feed pipe is provided on the corresponding conveying pipe;

[0011] A discharge pipe is provided on the corresponding conveying pipe;

[0012] Multiple connecting pipes are disposed outside multiple conveying pipes, with the two ends of the multiple connecting pipes respectively opposite to the ends of the corresponding conveying pipes.

[0013] Preferably, the outer diameter of the conveying pipe is the same as the inner diameter of the circular hole, and the length of the conveying pipe is greater than the length of the reactor body.

[0014] Preferably, the mixing component includes two mixing core bodies, which are located at both ends inside the conveying pipe. Each of the two mixing core bodies is fixedly connected to a second mixing core body at an adjacent end. Each of the two mixing core bodies is fixedly connected to a connecting ring at an opposite end. The two connecting rings are slidably inserted into two connecting slots. Multiple locking blocks are fixedly connected to the connecting rings, and the multiple locking blocks are inserted into corresponding locking slots.

[0015] Preferably, the thickness of the connecting ring is the same as the depth of the connecting groove, and the outer diameter of the connecting ring is the same as the inner diameter of the connecting groove.

[0016] Preferably, flange two is sleeved and fixed on the outer sides of both ends of the plurality of conveying pipes, and flange one is sleeved and fixed on the outer sides of both ends of the feed pipe, the discharge pipe and the plurality of connecting pipes. The plurality of flange two are fixedly connected to the corresponding flange one through a shaft. The inner diameter of the flange one is the same as the inner diameter of the connecting ring.

[0017] Preferably, the inner diameters of the feed pipe, the discharge pipe, and the multiple connecting pipes are all the same, and the inner diameter of the feed pipe is the same as the inner diameter of the end of the conveying pipe.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. By setting a conveying mechanism on the reactor body, and using the reactor body, heat exchange medium inlet pipe and heat exchange medium outlet pipe to make the heat exchange medium contact the conveying mechanism, the temperature of the conveying mechanism can be adjusted by the flowing heat exchange medium, thereby ensuring the reaction effect of the conveying mechanism. The feed pipe facilitates the conveying of materials into the corresponding conveying pipe. The mixing core body one and mixing core body two divide the material into multiple streams. The flow velocity in the middle of the material conveying pipe increases and the flow velocity at both ends decreases, breaking the stable state of material flow. This allows the materials to collide and shear with each other at different speeds, enhancing the turbulence intensity. The increased turbulence can generate more eddies and shear forces, thereby enabling the materials to be fully mixed. The materials will pass through multiple sets of mixing core bodies one and mixing core bodies two, thereby improving the mixing effect of the materials and thus improving the practicality of this static mixing tubular reaction device.

[0020] 2. By fixing flanges two to the outside of both ends of multiple conveying pipes, the use of multiple flanges two, multiple flanges one and multiple bolts makes it easy to install and fix the feed pipe, discharge pipe and multiple connecting pipes to the ends of multiple conveying pipes. If the bolts connected to multiple flanges two are removed, it is easy to disassemble, clean or replace the mixing core body one, mixing core body two and connecting ring. The disassembly and replacement operation is simple and convenient. Attached Figure Description

Detailed Implementation

[0026] 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.

[0027] Example 1

[0028] Please see Figure 1-5 In this embodiment of the present invention, a static mixing tubular reaction device includes: two support bases 100 and a conveying mechanism 200. A reactor body 110 is sleeved and fixed on the two support bases 100. Multiple circular holes 111 are opened at both ends of the reactor body 110. A heat exchange medium inlet pipe 120 and a heat exchange medium outlet pipe 130 are connected and fixed on the reactor body 110. The conveying mechanism 200 is disposed on the reactor body 110 and is used for conveying and mixing materials.

[0029] Specifically, the conveying mechanism 200 facilitates the conveying and thorough mixing of materials, thereby ensuring the reaction rate and effect between multiple materials. When the conveying mechanism 200 is in use, the heat exchange medium inlet pipe 120 facilitates the delivery of the heat exchange medium into the reactor body 110, and the heat exchange medium outlet pipe 130 facilitates the discharge of the heat exchange medium. Thus, the temperature of the conveying mechanism 200 is adjusted by the flowing heat exchange medium, thereby ensuring the reverse effect of the conveying mechanism 200.

[0030] like Figure 3-5 As shown, in this embodiment, the conveying mechanism 200 includes: multiple conveying pipes 210, a feed pipe 220, a discharge pipe 230, and multiple connecting pipes 240. The two ends of the multiple conveying pipes 210 are respectively fixedly connected to the inner wall of a corresponding circular hole 111. Each end of the conveying pipe 210 has a connecting groove 211, and the inner wall of the connecting groove 211 has multiple slots 212. A mixing component is disposed inside the conveying pipe 210. The feed pipe 220 is disposed on the corresponding conveying pipe 210, the discharge pipe 230 is disposed on the corresponding conveying pipe 210, and the multiple connecting pipes 240 are disposed on the outside of the multiple conveying pipes 210. The two ends of the multiple connecting pipes 240 are respectively opposite to the ends of the corresponding conveying pipes 210. The outer diameter of the conveying pipe 210 is equal to the diameter of the circular hole 111. The inner diameters of the holes 111 are the same, the length of the conveying pipe 210 is greater than the length of the reactor body 110, and the mixing assembly includes two mixing core bodies 260. The two mixing core bodies 260 are located at both ends inside the conveying pipe 210, and each of the two mixing core bodies 260 is fixedly connected to a mixing core body 261 at an adjacent end. Each of the two mixing core bodies 260 is fixedly connected to a connecting ring 262 at an opposite end, and the two connecting rings 262 are slidably inserted into two connecting grooves 211 respectively. Multiple locking blocks are fixedly connected to the connecting rings 262, and the multiple locking blocks are inserted into the corresponding locking grooves 212 respectively. The thickness of the connecting rings 262 is the same as the depth inside the connecting grooves 211, and the outer diameter of the connecting rings 262 is the same as the inner diameter of the connecting grooves 211.

[0031] The delivery pipe 210 is a tubular shell structure with a large inner diameter at both ends and a small inner diameter in the middle.

[0032] In this embodiment, the feed pipe 220 facilitates the conveying of materials into the corresponding conveying pipe 210. When the material passes through the mixing core body 260, it is divided into many tiny streams. These streams intersect and collide, thereby achieving mixing between different materials. When the material flows to the middle of the conveying pipe 210, the mixing core body 261 further divides the material into multiple streams, and the inner diameter of the middle of the conveying pipe 210 decreases, thereby accelerating the flow rate of the material and increasing the turbulence intensity. When the material flows from the middle of the inner side of the conveying pipe 210 to the end with a larger inner diameter, the flow rate decreases again. This change in material flow rate breaks up the material flow. The stable flow state allows materials to collide and shear at different speeds, further enhancing turbulence intensity. Increased turbulence generates more eddies and shear forces, enabling thorough mixing of materials. Multiple connecting pipes 240 connect multiple conveying pipes 210 into a single unit, allowing materials to pass through multiple mixing core bodies 260 and 261, improving the mixing effect and enhancing the practicality of the static mixing tubular reaction device. Furthermore, the thicker wall in the middle of the conveying pipe 210 allows it to withstand the pressure generated by the accelerated flow rate, ensuring the service life of the conveying pipe 210.

[0033] Example 2

[0034] Based on Example 1, in order to facilitate the disassembly and replacement of the hybrid core body 1 260 and the hybrid core body 261.

[0035] like Figure 3-5 As shown, in this embodiment, flanges 270 are fixedly fitted onto the outer sides of both ends of multiple conveying pipes 210, and flanges 250 are fixedly fitted onto the outer sides of both ends of the feed pipe 220, the discharge pipe 230, and multiple connecting pipes 240. Multiple flanges 270 are fixedly connected to the corresponding flanges 250 via shafts. The inner diameter of flanges 250 is the same as the inner diameter of connecting ring 262. The inner diameters of feed pipes 220, discharge pipes 230, and multiple connecting pipes 240 are all the same, and the inner diameter of feed pipe 220 is the same as the inner diameter of the end of conveying pipe 210.

[0036] In practice, multiple flanges 270, multiple flanges 250, and multiple bolts are used in conjunction to facilitate the installation and fixation of the feed pipe 220, discharge pipe 230, and multiple connecting pipes 240 to the ends of multiple conveying pipes 210. Removing the bolts connected to the flanges 270 facilitates the removal of the feed pipe 220, discharge pipe 230, multiple connecting pipes 240, and multiple flanges 250. Removing flanges 250 facilitates the removal of the mixing core body 260 and mixing core body 261 inside the conveying pipe 210. The connecting ring 262 can be pulled out, which facilitates the cleaning or replacement of the first mixing core body 260, the second mixing core body 261, and the connecting ring 262. The disassembly and replacement operation is simple and convenient. After the first mixing core body 260, the second mixing core body 261, and the connecting ring 262 are reinstalled, the connecting ring 262 can be limited by the locking block and the locking groove 212. The flange 250 after installation can also limit the connecting ring 262, which facilitates the fixing of the first mixing core body 260, the second mixing core body 261, and the connecting ring 262 after installation.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
