Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a reaction vessel for producing fluorescent whitening agents. Background Technology

[0002] Optical brighteners are fluorescent dyes, also known as white dyes, and are a general term for a class of compounds. They are an important product in the chemical industry with a wide range of applications. The production of optical brighteners requires a series of chemical reactions, such as condensation, distillation, and crystallization. These reactions require various raw materials to be placed in a reaction vessel, where they undergo a series of reactions to produce the optical brightener product. During the production process, the materials in the reaction vessel need to be stirred to ensure uniform mixing. However, currently, most reaction vessels use stirring shafts for stirring, which is a relatively simple method with low stirring efficiency, resulting in insufficient mixing of materials and affecting the reaction rate and product quality. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the prior art by providing a reaction vessel for producing fluorescent whitening agents.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A reaction vessel for producing fluorescent whitening agents, comprising a vessel body; A water supply pipe is vertically and rotatably mounted on the vessel body; An annular tube is rotatably disposed inside the vessel body, and a support tube connects the annular tube and the water supply pipe; A water spray pipe is fixedly installed on the annular pipe. The water spray pipe is vertically installed and has multiple first water spray holes. A water pump is installed on the water pump pipe, with one end connected to the vessel body and the other end rotatably connected to the water supply pipe. A stirring assembly is disposed inside the vessel and is used to stir the materials inside the vessel; A power unit, mounted on the vessel body, is used to drive the stirring assembly and the water supply pipe to rotate.

[0005] Preferably, the support pipe and the annular pipe are provided with a plurality of second water spray holes.

[0006] Preferably, the stirring assembly includes a rotating shaft rotatably disposed within the vessel body, a stirring blade is fixedly disposed on the rotating shaft, the rotating shaft is located on one side of the water supply pipe, and the annular pipe is located below the rotating shaft.

[0010] Preferably, the top of the vessel is provided with a feed pipe, and the bottom of the vessel is provided with a discharge pipe.

[0011] The beneficial effects of adopting the above technical solution are as follows: 1. In this utility model, the raw materials for producing fluorescent whitening agents are injected into the reactor body. The power component drives the stirring component to stir the raw materials in the reactor body, so that the raw materials are mixed evenly. During the stirring process, the water pump draws the raw materials in the reactor body through the water pumping pipe and transports them to the water supply pipe. The raw materials then flow through the support pipe, the annular pipe and the spray pipe in sequence, and finally spray out from the first spray hole, so that the raw materials can complete the circulation flow.

[0017] like Figures 1 to 3 As shown, a reaction vessel for producing fluorescent whitening agents includes a vessel body 1. A water supply pipe 2 is vertically rotatably mounted on the vessel body 1, located in the middle of the vessel body 1. The upper end of the water supply pipe 2 extends through the vessel body 1 to the top of the vessel body 1, and the lower end of the water supply pipe 2 is located inside the vessel body 1. An annular pipe 3 is rotatably mounted inside the vessel body 1, located in the lower part of the vessel body 1. A support pipe 4 connects the annular pipe 3 and the water supply pipe 2, thus connecting the water supply pipe 2 and the annular pipe 3. The water supply pipe 2 and the annular pipe 3 are coaxially arranged. Multiple water spray pipes 5 are fixedly mounted on the annular pipe 3, vertically arranged, and evenly distributed along the circumferential direction. The system is configured such that the water spray pipe 5 and the annular pipe 3 are connected, and the water spray pipe 5 has multiple first water spray holes 6 on its wall. The upper end of the water spray pipe 5 is a closed end, so that the liquid in the water spray pipe 5 can only be discharged from the first water spray holes 6. The water supply pipe 2 is also connected to the water suction pipe 7. One end of the water suction pipe 7 is rotatably connected to the upper end of the water supply pipe 2, and the other end of the water suction pipe 7 is connected to the lower part of the vessel body 1. The water suction pipe 7 is equipped with a water pump 8, which can be fixedly connected to the vessel body 1 through the bracket 19. The vessel body 1 is also equipped with a stirring assembly and a power assembly. The stirring assembly is used to stir the material in the vessel body 1, and the power assembly is used to drive the stirring assembly and the water supply pipe 2 to rotate.

[0018] In this invention, the raw materials used to produce fluorescent whitening agents are placed in a reactor body 1. A power unit drives a stirring unit to stir the raw materials in the reactor body 1, ensuring uniform mixing. To further enhance the uniformity of the mixture, a water extraction pipe 7 draws the raw materials from the reactor body 1 and transports them to a water delivery pipe 2. The raw materials flow along the water delivery pipe 2, support pipe 4, annular pipe 3, and spray pipe 5, and are finally returned to the reactor body 1 through the first spray hole 6 on the spray pipe 5, completing a cycle. During this cycle, the raw materials are further mixed, resulting in a uniform mixture. During the circulation of the raw materials within the reactor body 1, the power unit drives the water delivery pipe 2, support pipe 4, and annular pipe... 3. The water spray pipe 5 rotates inside the reactor body 1. During the rotation, the water spray pipe 5 can stir the raw materials in the reactor body 1, making the raw materials evenly mixed. In addition, after the fluorescent whitening agent is produced, the inside of the reactor needs to be cleaned to prevent the raw materials from remaining in the reactor body 1 and affecting the next reaction. During the cleaning process, clean water is injected into the reactor body 1 through the feed pipe 16, and the water pump 8 draws the clean water into the water supply pipe 2 through the water suction pipe 7. Finally, it is sprayed out from the first water spray hole 6 on the water spray pipe 5. The sprayed clean water can be sprayed on the side wall of the reactor body 1, which can clean the raw materials adhering to the side wall of the reactor body 1, prevent the raw materials from adhering to the side wall of the reactor body 1, and solve the problem of the reactor being difficult to clean.

[0019] Furthermore, the first water spray hole 6 is aligned with the water spray pipe 5 along the circumferential direction, so when the raw material is sprayed out from the first water spray hole 6, it can be directly sprayed onto the side wall of the vessel body 1 to clean the side wall of the vessel body 1.

[0020] Furthermore, the support pipe 4 and the annular pipe 3 are provided with a plurality of second water spray holes 9, which face upwards. During the circulation process, the raw materials can also be sprayed out from the second water spray holes 9, enabling the raw materials to circulate quickly. In addition, during the cleaning process, the upward-sprayed clean water can be directly sprayed onto the stirring component, which can clean the stirring component and make the reactor cleaner more thorough.

[0021] Furthermore, the water supply pipe 2 is provided with multiple third water spray holes 18 on the side wall inside the vessel body 1. The raw materials can also be sprayed out from the third water spray holes 18 to complete the circulation flow. At the same time, during the cleaning process of the vessel body 1, the clean water sprayed from the third water spray holes 18 can be directly sprayed onto the stirring component to clean the hard-to-clean dead corners on the stirring component, making the cleaning more thorough.

[0022] Furthermore, such as Figure 4As shown, the stirring assembly includes a rotating shaft 10, which is vertically rotatably disposed within the vessel body 1. The rotating shaft 10 is driven to rotate by a power assembly. A stirring blade 11 is fixedly disposed on the rotating shaft 10, and the stirring blade 11 is located inside the vessel body 1. The rotating shaft 10 and the stirring blade 11 are located on one side of the water supply pipe 2, and the annular pipe 3 is located below the rotating shaft 10. In this embodiment, the power assembly drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the stirring blade 11 to rotate, thereby stirring the raw materials in the vessel body 1 and making the raw materials evenly mixed. While the stirring blade 11 and the stirring shaft 10 are rotating and stirring, the raw materials flow and circulate in the water pumping pipe 7, the water supply pipe 2, the support pipe 4, the annular pipe 3, and the spray pipe 5. The raw materials are quickly and evenly mixed through both stirring and the circulation of the raw materials.

[0023] Furthermore, the power assembly includes a first gear 12 fixedly mounted on the water supply pipe 2, coaxially arranged with the water supply pipe 2. A second gear 13 is fixedly connected to the upper end of the rotating shaft 10, passing through the vessel body 1. The second gear 13 is coaxially arranged with the rotating shaft 10. Both the first gear 12 and the second gear 13 are located above the vessel body 1, meshing with each other. A motor 14 is fixedly mounted on the vessel body 1, and the motor 14 is drively connected to the second gear 13. In this embodiment, the motor 14 drives the second gear 13 to rotate. The second gear 13 is fixedly connected to the rotating shaft 10, thus driving the rotating shaft 10 to rotate within the vessel body 1, stirring the raw materials within the vessel body 1. Because the second gear 13 meshes with the first gear 12, it can drive the first gear 12 to rotate. Simultaneously, the rotation of the first gear 12 drives the water supply pipe 2 to rotate, causing the support pipe 4, the annular pipe 3, and the spray pipe 5 to rotate within the vessel body 1.

[0024] Furthermore, a fixing frame 15 is provided on the vessel body 1. The fixing frame 15 is fixedly installed at the upper end of the vessel body 1. The water supply pipe 2 is rotatably installed on the fixing frame 15, making the rotation of the water supply pipe 2 more stable. The upper end of the water supply pipe 2 extends to the top of the fixing frame 15 and is rotatably connected to the water pumping pipe 7. The water supply pipe 2 and the water pumping pipe 7 can be made of stainless steel. Therefore, the water supply pipe 2 is made of a hard material and is not easy to bend or break.

[0025] It should be noted that a bearing is installed between the water supply pipe 2 and the vessel body 1, and a bearing is installed between the water supply pipe 2 and the fixed frame 15, which enables the water supply pipe 2 to rotate more smoothly; a bearing is installed between the rotating shaft 10 and the vessel body 1, which makes the rotating shaft 10 rotate more smoothly and stably.

[0026] Furthermore, the motor 14 is fixedly mounted on the mounting bracket 15, and the output shaft of the motor 14 is fixedly connected to the upper end of the rotating shaft 10. Therefore, the motor 14 can drive the rotating shaft 10 to rotate. At the same time, the rotating shaft 10 is fixedly connected to the second gear 13, so it can drive the second gear 13 to rotate, and the first gear 12 meshing with the second gear 13 rotates synchronously.

[0027] In another embodiment, the motor 14 is fixedly mounted on the mounting frame 15, and a third gear is fixedly mounted on the output shaft of the motor 14. The third gear meshes with the second gear 13, and the second gear 13 is fixedly connected to the rotating shaft 10. After the motor 14 is started, it drives the third gear to rotate, which in turn drives the second gear 13, which meshes with the third gear, to rotate. Since the second gear 13 is fixedly connected to the rotating shaft 10, it can drive the rotating shaft 10 to rotate, thereby stirring the raw materials in the vessel 1.

[0028] Furthermore, a rotary joint is connected between the water supply pipe 2 and the water pumping pipe 7.

[0029] Furthermore, the top of the vessel body 1 is provided with a feed pipe 16, and the bottom of the vessel body 1 is provided with a discharge pipe 17. Both the feed pipe 16 and the discharge pipe 17 are provided with valves for opening and closing the pipes. The feed pipe 16 is used to inject raw materials into the vessel body 1, and the discharge pipe 17 is used to discharge the raw materials that have completed the reaction inside the vessel body 1.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
