Description

Technical Field

[0001] This utility model relates to the field of antibacterial hydrogel synthesis technology, and in particular to a isothermal catalytic synthesis device for antibacterial hydrogels. Background Technology

[0002] Antibacterial hydrogels are functional materials that combine polymers with antibacterial active substances, possessing both physical barrier properties and chemical bactericidal capabilities. They are widely used in medical, bioengineering, and other fields. Their core function is to inhibit or kill pathogenic microorganisms through the sustained release of antibacterial components, while simultaneously promoting tissue repair. The isothermal catalytic synthesis of antibacterial hydrogels typically involves activating a catalytic system through a chemical reaction at a specific temperature, promoting cross-linking of polymer chains or doping with functional molecules to form a gel network structure with antibacterial properties.

[0003] A search revealed a patent with publication number CN113578177B entitled "A Device for Preparing Hydrogel Dressings." The technical problem it addresses is that both the additives and raw materials have a certain liquid viscosity, requiring a prolonged mixing time to achieve the required uniformity for production. The device injects the compounding agent into the feeding chamber through a first feed pipe, while simultaneously injecting the raw materials through a second feed pipe. A premixing unit is incorporated to premix the compounding agent and raw materials before they enter the mixing chamber, preventing stratification caused by batch injection and hindering subsequent mixing. This setup facilitates preliminary mixing of the raw materials and compounding agent during injection, promoting uniform mixing and improving the uniformity of the dressing's function. However, the following drawbacks remain: the synthesis of antibacterial hydrogels requires constant temperature catalysis, but the uniformity of this temperature distribution needs improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a constant-temperature catalytic synthesis device for antibacterial hydrogels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A isothermal catalytic synthesis device for antibacterial hydrogels includes a tank, a discharge pipe fixedly installed at the bottom of the tank, a top cover fixedly installed at the top of the tank by bolts, an isothermal channel provided between the inner and outer circumferential walls of the tank, an electric heating strip fixedly installed on the outer side of the isothermal channel, a temperature uniform cover sleeved on the inner side of the isothermal channel, the electric heating strip sleeved on the temperature uniform cover, and a diffuser provided in each space of the temperature uniform cover.

[0007] Preferably, a fixed bracket is fixedly installed at the lower circumference of the tank body, and the fixed bracket includes multiple support rods, with a pressure-distributing block fixedly installed at the bottom of each support rod.

[0008] Preferably, a feeding cylinder is fixedly installed at one end of the top of the top cover, and a dust cover is snapped onto the top of the feeding cylinder. A drive motor is fixedly installed in the middle of the top of the top cover, and a mixing and stirring assembly is fixedly installed at the output end of the drive motor. The mixing and stirring assembly is located inside the tank.

[0009] Preferably, a controller is fixedly installed at the middle of the outer circumference of the tank.

[0010] Preferably, the heating strip is spiral-shaped, and the bottom end of the heating strip is attached to the bottom end of the tank.

[0011] Preferably, the diffuser includes a heat transfer column, and multiple heat dissipation fins at equal angles are fixedly connected around the circumference of the heat transfer column. Multiple temperature expansion plates at equal angles are fixedly installed at the outer end of the circumference of the heat transfer column, and the outer side of the heat transfer column is fixedly installed with the outer side of the constant temperature channel.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model proposes a constant-temperature catalytic synthesis device for antibacterial hydrogels. The device comprises a constant-temperature channel with heating elements, multiple diffusers, and a temperature uniform cover arranged sequentially from the outside to the inside. Each diffuser corresponds to a single space in the temperature uniform cover. When the controller activates the heating elements, the temperature inside the constant-temperature channel is rapidly increased and the heat distribution is uniform, resulting in a uniform temperature on the inner circumference of the tank. This allows the antibacterial hydrogel to be catalytically synthesized under constant-temperature conditions. The diffusers include heat transfer columns, multiple heat dissipation fins, and multiple temperature expansion plates. The heat transfer columns transfer heat to the heat dissipation fins and temperature expansion plates, while the heat from the heat dissipation fins is also transferred to the temperature expansion plates. This not only rapidly and uniformly equalizes the temperature inside the constant-temperature channel, but also improves the temperature uniformity rate.

[0014] 2. The present invention proposes a constant temperature catalytic synthesis device for antibacterial hydrogels. The heating strips are spiral-shaped and the bottom of the heating strips are attached to the bottom of the tank. This allows the heating strips to be arranged in an orderly and equidistant manner inside the constant temperature channel, which helps to accelerate the uniform temperature distribution inside the constant temperature channel.

Detailed Implementation

[0020] Reference Figure 1-4 A constant-temperature catalytic synthesis device for antibacterial hydrogel includes a tank 1, a discharge pipe 2 fixedly installed at the bottom of the tank 1, a top cover 3 fixedly installed at the top of the tank 1 by bolts, a constant-temperature channel 9 provided between the inner and outer circumferential walls of the tank 1, an electric heating strip 10 fixedly installed on the outer side of the constant-temperature channel 9, a temperature uniform cover 11 sleeved on the inner side of the constant-temperature channel 9, the electric heating strip 10 sleeved with the temperature uniform cover 11, and a diffuser 12 provided in each space of the temperature uniform cover 11.

[0021] In this utility model, a fixed bracket 7 is fixedly installed at the lower circumference of the tank body 1, and the fixed bracket 7 includes multiple support rods, with a pressure-distributing block 8 fixedly installed at the bottom of each support rod, which helps the tank body 1 to be placed stably and to work.

[0022] A feeding cylinder 5 is fixedly installed at one end of the top of the top cover 3, and a dust cover is snapped onto the top of the feeding cylinder 5 to prevent dust, water vapor and other substances from entering the tank 1 from the feeding cylinder 5. It also helps to keep the tank 1 warm and reduce heat loss. A drive motor 4 is fixedly installed in the middle of the top of the top of the top cover 3, and a mixing and stirring component is fixedly installed at the output end of the drive motor 4. The mixing and stirring component is located inside the tank 1. The mixing and stirring component helps to accelerate the catalytic synthesis of antibacterial hydrogel.

[0023] A controller 6 is fixedly installed at the middle of the outer circumference of the tank body 1. The controller 6 can control the operation of the heating strip 10 and the temperature inside the constant temperature channel 9.

[0024] The heating strip 10 is spiral-shaped, and the bottom end of the heating strip 10 is attached to the bottom end of the tank body 1, so that the heating strip 10 is arranged in an orderly and equidistant manner inside the constant temperature channel 9, which helps to accelerate the uniform temperature distribution inside the constant temperature channel 9.

[0025] The diffuser 12 includes a heat transfer column 13, and multiple equal-angle heat dissipation fins 14 are fixedly connected to the circumference of the heat transfer column 13. Multiple equal-angle temperature expansion plates 15 are fixedly installed at the outer end of the circumference of the heat transfer column 13. The outer side of the heat transfer column 13 is fixedly installed to the outer side of the constant temperature channel 9, so that the heat transfer column 13 transfers heat to the multiple heat dissipation fins 14 and the multiple temperature expansion plates 15. At the same time, the heat from the multiple heat dissipation fins 14 is also transferred to the multiple temperature expansion plates 15, so that the temperature uniform cover 11 not only quickly and evenly distributes the temperature inside the constant temperature channel 9, but also improves its temperature uniformity speed.

[0026] Working principle: The constant temperature channel 9 is provided with heating strips 10, multiple diffusers 12 and temperature uniform cover 11 arranged sequentially from the outside to the inside. Each diffuser 12 corresponds to each space of the temperature uniform cover 11. After the controller 6 turns on the heating strips 10, the temperature inside the constant temperature channel 9 can be raised quickly and the heat distribution is uniform, thereby making the temperature of the inner wall of the tank 1 uniform. This allows the antibacterial hydrogel to be catalyzed and synthesized in a constant temperature environment. The diffuser 12 includes heat transfer columns 13, multiple heat dissipation fins 14 and multiple temperature expansion plates 15. The heat transfer columns 13 transfer heat to the multiple heat dissipation fins 14 and multiple temperature expansion plates 15. At the same time, the heat from the multiple heat dissipation fins 14 is also transferred to the multiple temperature expansion plates 15. This makes the temperature uniform cover 11 not only quickly and uniformly uniform the temperature inside the constant temperature channel 9, but also improves its temperature uniformity speed.

[0027] The heating strip 10 is spiral-shaped, and its bottom end is attached to the bottom end of the tank body 1, so that the heating strip 10 is arranged in an orderly and equidistant manner inside the constant temperature channel 9, which helps to accelerate the uniform temperature distribution inside the constant temperature channel 9.
