Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a glass reaction vessel. Background Technology

[0002] Glass reactors are widely used in pharmaceuticals, fine chemicals, and other fields due to their excellent corrosion resistance and transparency. During the reaction process, to ensure uniform mixing and efficient heat transfer, a stirring mechanism is typically installed to continuously agitate the materials inside the reactor.

[0003] However, in many pharmaceutical synthesis or crystallization reactions, the reactants themselves have high viscosity, or solids precipitate during the reaction. These materials easily adhere to the smooth inner wall of the reaction vessel, forming a wall-hanging phenomenon. This adhered layer not only hinders the heat transfer efficiency of the vessel wall but also prevents these materials from fully participating in the reaction, directly affecting the yield and purity of the final product. This is a problem that urgently needs to be solved in pharmaceutical production with stringent quality requirements.

[0004] To address the issue of residue buildup on reactor walls, existing technologies have attempted to incorporate wall-scraping devices. However, glass reactors are expensive and fragile, and their inner walls are difficult to make perfectly spherical during manufacturing, resulting in dimensional tolerances. If a traditional rigid scraper is used, a safety gap must be maintained between the scraper and the vessel wall to avoid scratching or shattering the glass. This significantly reduces the scraping effectiveness, failing to effectively remove the deposits. Conversely, forcing a rigid scraper to adhere to the vessel wall creates enormous stress in areas with smaller inner diameters, posing a high risk of equipment damage. Therefore, it is difficult to achieve effective wall scraping while ensuring safety.

[0005] Therefore, this utility model proposes a glass reactor to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the glass reactor, due to the fragility of the reactor body material and the existence of manufacturing tolerances, the rigid wall scraping device is unable to effectively remove the material adhering to the wall while ensuring safety, thus affecting the reaction efficiency and product purity. The present invention aims to provide a glass reactor with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a glass reaction vessel, which includes a reaction assembly, a motor, a stirring mechanism, and a wall scraping assembly. The reaction assembly includes a reaction vessel. The stirring mechanism is disposed inside the reaction vessel and includes a stirring shaft that is driven and connected to the motor. The stirring mechanism also includes a connecting ring fixedly connected to the stirring shaft and a support frame that extends radially from the connecting ring and is fixedly connected to it. The wall scraping assembly is fixedly connected to the free end of the support frame. The wall scraping assembly includes a mounting base fixed to the support frame, a scraper slidably accommodated in the mounting base, and a spring accommodated in the mounting base for elastically pushing the scraper. The spring is disposed between the inner bottom wall of the mounting base and the inner side surface of the scraper.

[0008] Preferably, the wall scraping assembly further includes scraping teeth; the scraping teeth are fixedly connected to both sides of the scraper and work in conjunction with the scraper to enhance the peeling and scraping effect on the material adhering to the inner wall of the reaction vessel.

[0009] Preferably, the stirring mechanism further includes stirring blades; the stirring blades extend radially from the connecting ring and are fixedly connected thereto, and when the stirring shaft rotates, the stirring blades shear, circulate and mix the materials in the reaction vessel.

[0010] Preferably, the stirring unit, which is composed of the connecting ring, the stirring blade and the support frame, is provided in two sets; the two sets of stirring units are symmetrically distributed vertically along the axial direction of the stirring shaft. This layout ensures that the material can be fully turned and mixed in the vertical direction, avoiding material sedimentation at the bottom of the vessel or uneven mixing of the upper layer of material.

[0011] Preferably, the stirring mechanism further includes a support base; the support base is fixed to the bottom of the reaction vessel, providing stable rotational support for the lower end of the stirring shaft, ensuring the stability and concentricity of the stirring shaft during high-speed rotation.

[0012] Preferably, the reaction assembly further includes a top cover; the top cover is detachably and sealed to the reaction vessel, together forming a closed reaction space, which facilitates feeding, discharging, and chemical reaction under specific pressure or atmosphere.

[0013] Preferably, the length direction of the scraper is parallel to the axial direction of the stirring shaft; this arrangement makes the contact line between the scraper and the inner wall of the reaction vessel a perpendicular line, increasing the effective scraping area during a single rotation and improving the overall wall scraping efficiency.

[0014] Preferably, the stirring blade is blade-shaped, and its blade plane has a preset angle with the axial direction of the stirring shaft; this angle design can generate axial thrust on the material when the stirring blade rotates, causing the material to form vertical convection in the vessel, thereby enhancing the overall macroscopic mixing effect.

[0015] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that rigid scrapers are difficult to adapt to the tolerance of glass vessel bodies and are prone to damage by setting a wall scraping component on a support frame that rotates with the stirring mechanism and using a spring to push the scraper in the wall scraping component, so that the scraper can flexibly fit the inner wall of the reaction vessel. It achieves the technical effect of adaptively and non-damagingly scraping off the wall-adhering material, thereby significantly improving the mixing uniformity and reaction yield.

[0016] 2. This utility model solves the problem of complex equipment structure and the need for multiple drive sources caused by the separation of stirring and wall scraping functions in the prior art by integrating the wall scraping component onto the stirring mechanism and driving it with the same motor. It achieves the technical effect of simplifying the overall structure, reducing energy consumption and ensuring that wall scraping and stirring are carried out synchronously.

[0017] 3. This utility model solves the problem of inconsistent reactions between upper and lower layers caused by uneven vertical mixing of materials in traditional reactors by symmetrically setting stirring mechanisms on the stirring shaft. It achieves the technical effect of promoting the overall circulation of materials in the reactor and ensuring highly uniform reaction conditions. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Please refer to Figures 1 to 4 This utility model provides a glass reactor, which aims to solve the problem that in the prior art, the stirring mechanism 4 and the wall scraping mechanism of the glass reactor are structurally separated, and the rigid scraper is difficult to adapt to the tolerance of the inner wall of the glass reactor, resulting in the drug sticking to the wall and poor scraping effect.

[0022] like Figure 1 and Figure 2 As shown, the glass reactor includes a reaction assembly 1, a motor 2, and a stirring mechanism 4. The motor 2 is located on the upper part of the reaction assembly 1, and the stirring mechanism 4 is located inside the reaction assembly 1. The reaction assembly 1 includes a reaction container 101 and a top cover 102. The top cover 102 is detachably and sealed to the reaction container 101. The stirring mechanism 4 includes a stirring shaft 401 vertically arranged inside the reaction container 101. The stirring shaft 401 is connected to the motor 2 via a connector 3. The stirring mechanism 4 also includes a connecting ring 403 fixedly connected to the stirring shaft 401. A support frame 404 extending radially from the connecting ring 403 is fixedly connected to the connecting ring 403. The reactor also includes a wall scraping assembly 5, which is fixedly connected to the free end of the support frame 404.

[0023] Please refer to the following carefully. Figure 3 and Figure 4 The wall scraping assembly 5 includes a mounting base 501, a scraper 502, and a spring 504. The mounting base 501 is fixed to the free end of the support frame 404. The scraper 502 is slidably accommodated in the mounting base 501. The outer side of the scraper 502 is used to adhere to the inner wall of the reaction vessel 101. The length direction of the scraper 502 is parallel to the axial direction of the stirring shaft 401. The spring 504 is a compression spring 504, which is accommodated in the mounting base 501 and is located between the inner bottom wall of the mounting base 501 and the inner side of the scraper 502. The spring 504 always applies a radially outward thrust to the scraper 502, so that the scraper 502 adheres tightly to the inner wall of the reaction vessel 101. The wall scraping assembly 5 also includes scraper teeth 503, which are fixedly connected to both sides of the scraper 502 and adhere to the inner wall of the reaction vessel 101 under the same thrust of the spring 504 as the scraper 502.

[0024] Please refer to Figure 2 and Figure 3To achieve mixing and stirring of materials, the stirring mechanism 4 also includes stirring blades 402. The stirring blades 402 extend radially from the connecting ring 403 and are fixedly connected to it. The stirring blades 402 are blade-shaped, and their blade planes have a preset angle with the axial direction of the stirring shaft 401. Two sets of stirring units are provided, which are composed of the connecting ring 403, stirring blades 402 and support frame 404. The two sets of stirring units are symmetrically fixedly arranged up and down along the axial direction of the stirring shaft 401.

[0025] To ensure the stability of the rotation of the stirring shaft 401, the stirring mechanism 4 also includes a support base 405, which is fixed to the bottom of the reaction vessel 101, and the lower end of the stirring shaft 401 is rotatably inserted into the support base 405.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, to enhance the wall scraping effect, please refer to... Figure 3 and Figure 4 The wall scraping assembly 5 also includes scraper teeth 503, which are fixedly connected to both sides of the scraper 502 and are used to assist in scraping off the material adhering to the inner wall of the reaction vessel 101.

[0027] As another preferred embodiment, in order to achieve mixing of materials, please refer to... Figure 3 The stirring mechanism 4 also includes a stirring blade 402, which extends radially from the connecting ring 403 and is fixedly connected thereto.

[0028] As a further optimization of the stirring blade 402, in order to improve the mixing efficiency, the stirring blade 402 is blade-shaped, and its blade plane has a preset angle with the axial direction of the stirring shaft 401, so as to generate a more complex flow field when rotating.

[0029] As a preferred overall layout of the stirring mechanism 4, in order to achieve uniform mixing of materials inside the vessel, two sets of stirring units are provided, consisting of a connecting ring 403, stirring blades 402, and support frame 404, and these two sets of stirring units are symmetrically distributed vertically along the axial direction of the stirring shaft 401.

[0030] As a preferred embodiment, to ensure the rotational stability of the stirring shaft 401, please refer to... Figure 2 The stirring mechanism 4 also includes a support base 405, which is fixed to the bottom of the reaction vessel 101, and the lower end of the stirring shaft 401 is rotatably inserted into the support base 405.

[0031] As a preferred embodiment, in order to construct a closed reaction space, please refer to... Figure 2 The reaction assembly 1 also includes a cover 102, which is detachably and sealed to the reaction vessel 101.

[0032] In a preferred embodiment, to ensure the effectiveness of the contact surface between the scraper 502 and the vessel wall, the length direction of the scraper 502 is parallel to the axial direction of the stirring shaft 401.

[0033] Working principle: When the motor 2 starts, it drives the stirring shaft 401 to rotate through the connector 3. The connecting ring 403, stirring blade 402 and support frame 404, which are fixedly connected to the stirring shaft 401, rotate synchronously. The stirring blade 402 mixes and stirs the materials in the reaction vessel 101, while the symmetrically arranged stirring units ensure the uniformity of material mixing in the vertical direction.

[0034] While the stirring mechanism 4 rotates, the scraping assembly 5, fixed to the support frame 404, moves synchronously along the inner wall of the reaction vessel 101. Inside the scraping assembly 5, the spring 504 always applies a radially outward elastic thrust to the scraper 502. This thrust allows the scraper 502 and the scraping teeth 503 on both sides to continuously and tightly adhere to the inner wall of the reaction vessel 101. Due to the elastic effect of the spring 504, this structure can automatically compensate for the gap changes caused by the eccentric rotation of the stirring mechanism 4 or the manufacturing tolerance of the reaction vessel 101, thereby achieving dynamic and continuous scraping of the inner wall of the vessel, effectively preventing material adhesion and ensuring thorough mixing of materials.
