A heat preservation device for preparing gel

Abstract

This invention provides a heat-insulating device for preparing gels, aiming to solve the technical problem that existing heat-insulating equipment has poor heat-insulating effect on high-viscosity, low-flowability gel raw materials. The heat-insulating device includes: an outer shell; an inner liner disposed inside the outer shell, with a heat-insulating medium filling the gap between the inner liner and the outer shell; multiple conduits disposed on the inner liner, with both ends extending from the sides of the inner liner; and a submersible pump disposed in the gap between the inner liner and the outer shell, submerged in the heat-insulating medium, with the pump's output port connected to one end of each conduit. During the heat-insulating process, the heat-insulating medium directly exchanges heat with the gel raw material inside the inner liner through the outer wall of the inner liner. Simultaneously, the submersible pump drives the heat-insulating medium through the conduits, and the gel raw material in the middle of the inner liner maintains a constant temperature under the action of the heat-insulating medium in the conduits. This ensures that the temperature distribution inside the gel raw material in the inner liner is uniform during the heat-insulating process.

Description

Technical Field

[0001] This utility model relates to a heat preservation device for preparing gels. Background Technology

[0002] In the field of preparing hydrogels for water-light injection, existing technologies (such as CN118286505A) disclose a typical method. A key step in this method involves crosslinking sodium hyaluronate (HA-Na) with 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC·HCl) at a molar ratio of 0.5 to 2:1 at a specific reaction temperature (30°C). However, this process requires precise isostatic control of the reaction system (especially materials with significantly reduced fluidity or those that have formed a gel). Current conventional heat preservation equipment generally suffers from low heat transfer efficiency and uneven temperature distribution when processing such high-viscosity, low-flowability gel raw materials, making it difficult to ensure that the material as a whole is stably maintained at the required 30°C reaction temperature, resulting in unsatisfactory heat preservation effects.

[0019] Example

[0020] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment discloses a heat-insulating device for preparing gels, including an outer shell 10, an inner liner 20, a conduit 30, and a submersible pump 40. The inner liner 20 is disposed inside the outer shell 10, and there is a gap between the inner liner 20 and the outer shell 10. The gap is filled with a heat-insulating medium, which is generally warm water. The inner liner 20 and the outer shell 10 are usually connected by multiple support columns.

[0021] Multiple conduits 30 are provided in the inner liner 20. The two ends of the conduits 30 extend from both sides of the inner liner 20, so that both ends of the conduits 30 are located in the gap between the inner liner 20 and the outer shell 10.

[0022] The submersible pump 40 is disposed in the gap between the inner liner 20 and the outer shell 10. The submersible pump 40 is submerged in the insulation medium, and the output port of the submersible pump 40 is connected to one end of all the conduits 30, thereby driving the insulation medium to flow in the conduits 30 through the submersible pump 40.

[0023] Generally, the conduit 30 and the inner liner 20 are made of copper or aluminum to improve thermal conductivity.

[0024] In this embodiment, the gel material that needs to be kept warm is placed in the inner liner 20. During the heat preservation process, the heat preservation medium between the inner liner 20 and the outer shell 10 directly exchanges heat with the gel material inside the inner liner 20 through the outer wall of the inner liner 20. At this time, the gel material in the inner liner 20 near its outer wall is in a constant temperature maintenance state.

[0025] At the same time, the submersible pump 40 drives the insulation medium to pass through the conduit 30, and the gel material in the middle of the inner liner 20 is kept at a constant temperature under the action of the insulation medium in the conduit 30.

[0026] This technical solution ensures that the temperature distribution inside the gel material in the inner liner 20 is uniform during the heat preservation process.

[0027] In one specific embodiment: The insulation device also includes a heating component 50, which is disposed in the gap between the outer shell 10 and the inner liner 20. Its main function is to maintain the temperature of the insulation medium in a stable state.

[0028] Generally, the heating assembly 50 includes a heating element and a power supply kit for the heating element.

[0029] In another specific embodiment: The section of the conduit 30 located in the inner liner 20 has a rectangular cross-section. By designing the conduit 30 as a rectangular flat structure, the heat exchange efficiency between the gel material and the heat insulation medium in the conduit 30 can be increased.

[0030] In another specific embodiment: To improve the uniformity of temperature distribution of the gel raw material, all conduits 30 are arranged parallel to each other and evenly distributed in the inner liner 20.

[0031] In another specific embodiment: The heat preservation device also includes a stirring assembly 60, which is located in the inner liner 20 and is used to stir the gel raw material. The raw material between two adjacent conduits 30 is also in a state of poor flowability. Therefore, the stirring assembly 60 can promote the flow of the gel raw material, thereby improving the uniformity of temperature distribution.

[0032] Specifically, the inner liner 20 is detachably provided with a cover 70, and the stirring assembly 60 is provided on the cover 70. The output part of the stirring assembly 60 is located in the inner liner 20.

[0033] The stirring assembly 60 includes a main shaft 61, a motor 62 and a drive plate 63. The top end of the main shaft 61 is rotatably mounted on the cover 70 and extends out of the cover 70. The bottom end of the main shaft 61 extends toward the bottom of the inner liner 20. The main shaft 61 is located between two adjacent guide tubes 30.

[0034] The motor 62 is located on the top of the cover 70, outside the inner liner 20. The output shaft of the motor 62 is poweredly connected to the top of the main shaft 61 to drive the main shaft 61 to rotate.

[0035] The drive plate 63 is mounted on the main shaft 61 and located in the inner liner 20. Multiple drive plates 63 are evenly distributed around the main shaft 61.

[0036] In this embodiment, the motor 62 drives the main shaft 61 to rotate, thereby driving the drive plate 63 through the main shaft 61, and the drive plate 63 stirs the gel material in the inner liner 20 to promote the flow of the gel material.

[0037] Preferably, the inner liner 20 is provided with multiple main shafts 61, the top ends of all main shafts 61 are poweredly connected to the output shaft of the motor 62, and each main shaft 61 is provided with a drive plate 63. In this application, the output shaft of the motor 62 and the top ends of all main shafts 61 are powered through a gear meshing structure.

[0038] Preferably, the drive plate 63 has a spiral structure, thereby driving the gel material to flow not only laterally but also longitudinally during the stirring process. It is understood that in this embodiment, the lateral direction is perpendicular to the main shaft 61, and the longitudinal direction is parallel to the main shaft 61.

[0039] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
