Description

Technical Field

[0001] This utility model belongs to the field of sodium methoxide processing technology, and in particular relates to a sodium methoxide stirring and cooling device. Background Technology

[0002] Sodium methoxide is a chemical process that produces sodium methoxide by reacting it with methanol under an inert gas atmosphere. The reaction is violent and exothermic, so the temperature must be strictly controlled and a cooling system must be provided. The sodium methoxide produced is usually stored in the form of a methanol solution or further processed into a solid. The entire process must be isolated from air and moisture. It is mainly used as a catalyst in the production of pharmaceuticals, pesticides and biodiesel.

[0003] In the existing technology, the synthesis process of sodium methoxide has a significant exothermic effect, which leads to an increase in the temperature of the reaction system. Since the reaction temperature directly affects the purity and yield of sodium methoxide, excessively high temperatures can easily trigger side reactions (such as the formation of sodium formate or decomposition), thereby reducing the quality of the product and affecting the stability of the process and the performance of the product.

[0004] Based on this, the present invention designs a sodium methoxide stirring and cooling device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problem that the synthesis process of sodium methoxide in the prior art has a significant exothermic effect, which leads to an increase in the temperature of the reaction system. Since the reaction temperature directly affects the purity and yield of sodium methoxide, excessively high temperatures can easily trigger side reactions (such as the formation of sodium formate or decomposition), thereby reducing product quality and affecting process stability and product performance. Therefore, this invention proposes a sodium methoxide stirring and cooling device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sodium methoxide stirring and cooling device includes a base plate, a support frame fixedly connected to the base plate, a rolling assembly installed on the support frame, a stirring tank placed on the rolling assembly, a cooling device assembled outside the stirring tank, and a recovery device assembled on the base plate.

[0008] The cooling device includes a sealing shell, which is fitted over the mixing tank. The sealing shell has two openings inside, and sealing plugs are fitted inside the openings.

[0009] As a further description of the above technical solution:

[0010] The cooling device also includes a movable plate, and four elastic telescopic rods are fixedly connected inside the movable plate, with the elastic telescopic rods fixedly connected inside the sealed shell.

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

[0012] The sealing plug is a flexible rubber plug, and the sealing plug is fixedly connected inside the movable plate.

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

[0014] The inner diameter of the opening is larger than the diameter of the sealing plug's cross-section.

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

[0016] The recycling device includes a receiving box, which is fixedly connected to the upper surface of the base plate. A protective box is fixedly connected inside the receiving box, and an electric push rod is fixedly connected inside the protective box. A push rod is fixedly connected to the output end of the electric push rod.

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

[0018] An extrusion block is fixedly connected to the upper surface of the push rod, and a protective plate is provided on the outer sleeve of the push rod.

[0019] As a further description of the above technical solution:

[0020] The support frame has a circular hole, and the protective plate is tapered, with the diameter of the protective plate's cross-section being larger than the inner diameter of the protective box.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] In this invention, ice water or coolant is injected into the mixing tank through the upper opening. When the mixing tank rotates, the coolant accumulates at the bottom of the tank under centrifugal force, achieving continuous cooling of the outer wall of the mixing tank. After processing, one of the openings of the mixing tank is moved directly above the extrusion block. At this time, the electric push rod is activated, and its output shaft drives the push rod to move linearly. The extrusion block at the end of the push rod then applies axial thrust to the sealing plug, causing the sealing plug to disengage from the opening. After the seal is released, the coolant is discharged through the opening under gravity, first flowing to the surface of the inclined protective plate, and then guided along the protective plate to the receiving box, completing the centralized recovery of the coolant. This design not only ensures efficient heat exchange during the mixing process but also realizes the automated recovery of the cooling medium. Attached Figure Description

Detailed Implementation

[0029] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-4 ;

[0031] This utility model provides a technical solution: a sodium methoxide stirring and cooling device, including a base plate 1, a support frame 2 fixedly connected to the base plate 1, a rolling assembly 3 installed on the support frame 2, a stirring tank 4 placed on the rolling assembly 3, a cooling device 5 assembled outside the stirring tank 4, and a recovery device 7 assembled on the base plate 1.

[0032] The cooling device 5 includes a sealing shell 501, which is fitted over the mixing tank 4. The sealing shell 501 has two openings 502 inside, and a sealing plug 504 is fitted inside the openings 502.

[0033] Specifically, such as Figure 2-4As shown, the cooling device 5 also includes a movable plate 503, which has four elastic telescopic rods 505 fixedly connected inside. The combination design of the elastic telescopic rods 505 and the movable plate 503 realizes the automatic reset function of the sealing plug 504. When the electric push rod 703 drives the extrusion block 705 to apply pressure to the sealing plug 504, the movable plate 503 moves smoothly under the guidance of the elastic telescopic rods 505, ensuring that the sealing plug 504 accurately disengages from the opening 502. After the force is released, the restoring force of the elastic telescopic rods 505 drives the movable plate 503 to reset, so that the sealing plug 504 re-seals the opening 502. This structure not only simplifies the operation process, but also avoids the wear problem of traditional threaded or snap-on seals, significantly improving the sealing reliability and service life of the device.

[0034] Furthermore, the elastic telescopic rod 505 is fixedly connected inside the sealing shell 501, and the sealing plug 504 is set as an elastic rubber plug, which is fixedly connected inside the moving plate 503. The inner diameter of the opening 502 is larger than the diameter of the cross-section of the sealing plug 504, and the inner diameter of the opening 502 is slightly larger than the diameter of the cross-section of the sealing plug 504, forming a clearance fit. This design allows the sealing plug 504 to smoothly disengage from the opening 502 when under pressure, while relying on the elastic deformation of the rubber plug to compensate for dimensional tolerances and ensure the sealing performance when not open or closed. This dynamic sealing method is suitable for the rotation of the mixing tank 4 and avoids accidental leakage caused by vibration.

[0035] The recycling device 7 includes a receiving box 701, which is fixedly connected to the upper surface of the base plate 1. A protective box 702 is fixedly connected inside the receiving box 701. An electric push rod 703 is fixedly connected inside the protective box 702. A pushing rod 704 is fixedly connected to the output end of the electric push rod 703. A squeezing block 705 is fixedly connected to the upper surface of the pushing rod 704. A protective plate 706 is fitted over the pushing rod 704. A circular hole 6 is provided inside the support frame 2. The protective plate 706 is tapered, and the diameter of the cross-section of the protective plate 706 is larger than that of the protective plate. The inner diameter of the protective box 702, the conical protective plate 706 and the protective box 702 form a graded flow guiding system, which effectively optimizes the coolant recovery efficiency. When the coolant is discharged from the port 502, the conical protective plate 706 uses its inclined structure to disperse and guide the liquid, avoiding splashing. At the same time, the protective box 702 forms a closed protection for the electric push rod 703 and the push rod 704 to prevent liquid from seeping into the drive components. This design not only ensures the corrosion resistance of key components, but also ensures that all coolant flows into the receiving box 701 in a directional manner, reducing media loss.

[0036] Working principle: Ice water or coolant is injected into the mixing tank 4 through the upper port 502. When the mixing tank 4 rotates, the coolant accumulates at the bottom of the tank under the action of centrifugal force, achieving continuous cooling of the outer wall of the mixing tank 4. After processing, one of the ports 502 of the mixing tank 4 is moved directly above the extrusion block 705. At this time, the electric push rod 703 is activated, and its output shaft drives the push rod 704 to move linearly. The extrusion block 705 at the end of the push rod 704 then applies an axial thrust to the sealing plug 504, causing the sealing plug 504 to disengage from the port 502. After the seal is released, the coolant is discharged through the port 502 under the action of gravity. It first flows to the surface of the inclined protective plate 706, and then is guided along the protective plate 706 to the receiving box 701, completing the centralized recovery of the coolant. This design not only ensures efficient heat exchange during the mixing process, but also realizes the automated recovery of the cooling medium.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
