Description

Technical Field

[0001] This utility model relates to the field of surfactant production technology, and in particular to a closed reaction vessel for surfactant production that is easy to feed. Background Technology

[0002] In the production process of surfactants, it is usually necessary to mix, heat and react solid raw materials (such as alkylbenzene, fatty acids, caustic soda, etc.) with liquid raw materials in a reaction vessel.

[0003] According to Chinese Patent Publication No. CN223010559U, a closed reaction vessel for surfactant production that facilitates feeding is provided. It is equipped with a storage tank, a feed inlet, a sealing cover, a feed pipe, a flow control valve, and a support column. By opening the sealing cover, the reactant can be pre-placed in the storage tank through the feed inlet. When feeding is required, the flow control valve can be opened to feed directly, making feeding more sealed and convenient.

[0004] According to the existing technology, when solid raw materials are fed into the reactor body through the storage tank and the feed port, the solid raw materials are prone to clumping and agglomeration inside the storage tank. In addition, when falling into the reactor body, the material will only fall into one place and cannot be evenly dispersed into the material inside the reactor body, which makes it difficult for the solid raw materials to fully dissolve and react, resulting in incomplete reaction and affecting the yield and quality of the product. Therefore, a closed reactor for surfactant production that is easy to feed is proposed to solve the above problems. Utility Model Content

[0024] like Figure 1-4 As shown, the present invention proposes a closed reaction vessel for surfactant production that facilitates feeding, comprising a reaction vessel body 1, a top cover 2 on the top of the reaction vessel body 1, a first reduction motor 3 on the top of the top cover 2, a stirring shaft 4 extending into the interior of the reaction vessel body 1 connected to the output shaft of the first reduction motor 3, a plurality of evenly distributed stirring blades 5 on the outer side of the stirring shaft 4, and a feeding mechanism 6 on the top of the top cover 2.

[0025] In this invention, by starting the first reduction motor 3, the output shaft of the first reduction motor 3 will drive the stirring shaft 4 to rotate, and the stirring shaft 4 will drive multiple stirring blades 5 to rotate. The raw materials can be mixed and stirred by the rotation of the stirring blades 5.

[0026] Solid raw materials can be fed into the reactor body 1 through the feeding mechanism 6. At the same time, the solid raw materials are crushed and controlled, making the feeding of solid raw materials more sealed and accurate, and also making the mixing of materials more thorough, thus improving the mixing efficiency of active surface agents.

[0027] In Embodiment 1, the feeding mechanism 6 includes four mounting rods 61 located on the top of the top cover 2. A storage box 62 is located on the top of the four mounting rods 61. A feeding component 63 is located on the top of the storage box 62 for adding raw materials into the storage box 62. The storage box 62 can be installed and supported by the four mounting rods 61, and raw materials can be added into the storage box 62 by the feeding component 63. At the same time, after adding raw materials, the sealing of the storage box 62 is also ensured.

[0028] The top of the top cover 2 is provided with two vertical plates, and a crushing box 65 is provided between the opposite sides of the two vertical plates. A connecting component 66 is provided on the top of the crushing box 65, and a crushing component 67 is provided inside the crushing box 65 for crushing raw materials. A feeding component 64 extending into the top cover 2 is provided at the bottom of the crushing box 65. A dispersing disc 68 located above the stirring blade 5 is provided on the outside of the stirring shaft 4. Multiple evenly distributed through holes 69 are provided on the inner bottom wall of the dispersing disc 68 that extend to its bottom.

[0029] The material inside the storage box 62 can be accurately fed into the crushing box 65 through the connecting component 66. The solid material is crushed by the crushing component 67 inside the crushing box 65. After crushing, the crushed material enters the dispersing plate 68 through the feeding component 64.

[0030] When the stirring shaft 4 rotates, it drives the dispersion disk 68 to rotate. When the dispersion disk 68 rotates, it drives the material inside it to rotate. Under the action of centrifugal force, the material inside the dispersion disk 68 is thrown into the liquid medium inside the reactor body 1 as evenly as possible through multiple through holes 69, which promotes the rapid dispersion and mixing of the material and improves the reaction efficiency and quality.

[0031] In embodiment 2, the feeding assembly 63 includes a feeding pipe 631 connected to the top of the storage tank 62. The top of the feeding pipe 631 is threadedly connected to a pipe cap 632, and a rubber sealing gasket is provided between the top of the feeding pipe 631 and the inner top of the pipe cap 632.

[0032] Rotate the tube cover 632 to remove it, and then add the material into the storage box 62 through the feeding tube 631. After the material is added, place the tube cover 632 on top of the feeding tube 631 and rotate it in the opposite direction. This will seal the top of the feeding tube 631 with the tube cover 632 and the rubber sealing gasket, effectively preventing dust from escaping during feeding and protecting the production environment.

[0033] In embodiment 3, the connecting component 66 includes a first feeding hopper 661 connected to the bottom of the storage box 62. The bottom of the first feeding hopper 661 is connected to a connecting pipe 662. The other end of the connecting pipe 662 is connected to the top of the crushing box 65. A flow control valve 663 is provided on the inner side of the connecting pipe 662.

[0034] When feeding is required, the flow control valve 663 is opened, and the material inside the storage tank 62 will enter the crushing box 65 through the first feeding funnel 661 and the connecting pipe 662. The flow control valve 663 can ensure the accuracy of feeding and ensure the production effect of surfactant.

[0035] In embodiment four, the crushing assembly 67 includes a second reduction motor 671 installed on one side of the crushing box 65, and a crushing shaft 672 extending into the crushing box 65 is connected to the output shaft of the second reduction motor 671. A plurality of evenly distributed crushing blades 673 are provided on the outer side of the crushing shaft 672.

[0036] When the flow control valve 663 is opened, the second reduction motor 671 is started simultaneously. The output shaft of the second reduction motor 671 drives the crushing shaft 672 to rotate, and the crushing shaft 672 drives multiple crushing blades 673 to rotate. The multiple rotating crushing blades 673 can crush agglomerated and clumped materials, avoiding the problem that lumpy materials are difficult to disperse and dissolve after entering the reactor body 1, and creating good conditions for subsequent uniform reaction.

[0037] In embodiment 5, the feeding assembly 64 includes a second feeding hopper 641 connected to the bottom of the crushing box 65. The bottom of the second feeding hopper 641 is connected to a feeding pipe 642. The other end of the feeding pipe 642 extends into the interior of the top cover 2 and is located above the dispersing disc 68.

[0038] After the material is crushed, it can be fed into the interior of the reactor body 1 through the second feeding funnel 641 and the feed pipe 642, and fall directly into the interior of the dispersion plate 68. Through the high-speed rotation of the dispersion plate 68, the material can be evenly distributed into the liquid raw material through multiple through holes 69 as much as possible.

[0039] In embodiment six, a liquid material adding mechanism can also be provided on the top of the top cover 2. The liquid material adding mechanism includes only an installation rod 61, a storage tank 62, a feeding component 63, and a connecting component 66. The liquid material is stored in the storage tank 62 and added into the storage tank 62 by the feeding component 63. The bottom end of the connecting pipe 662 is directly connected to the inside of the top cover 2. The flow control valve 663 controls the quantitative addition of liquid material into the reactor body 1 through the connecting pipe 662.

[0040] In the feeding mechanism 6, the flow control valve 663 is a solid flow control valve, and in the liquid material adding mechanism, the flow control valve 663 is a liquid flow control valve.

[0041] In Example 7, both the outer sides of the reactor body 1 and the top cover 2 are provided with connecting rings 7, and the two connecting rings 7 are connected by multiple sets of bolt threads.

[0042] The reactor body 1 and the top cover 2 can be connected and installed through two connecting rings 7 and multiple sets of bolt threads, which facilitates the cleaning of the inside of the reactor body 1 and the top cover 2.

[0043] Example 8: An observation window is provided on the outside of the reactor body 1, a controller is provided on the outside of the reactor body 1, a feed pipe is connected to the bottom of the reactor body 1, and four evenly distributed support bases are provided at the bottom of the reactor body 1.

[0044] The material mixing and reaction inside the reactor body 1 can be observed through the observation window. A valve is installed inside the feed pipe, through which the surfactant that has completed the reaction can be discharged. The reactor body 1 can be supported by the support base.

[0045] The first geared motor 3, the flow control valve 663, and the second geared motor 671 are all electrically connected to the controller. The controller can control the first geared motor 3, the flow control valve 663, and the second geared motor 671. The feeding speed can be precisely controlled through the flow control valve 663 and the controller.
