Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermal insulation pipe technology, specifically to a silicone tube jacket constant temperature device. Background Technology
[0002] In the pharmaceutical industry, pipelines with both insulation and heating functions are needed to transport heated liquid materials. These pipelines provide insulation or auxiliary heating during transport to maintain a constant temperature, especially for highly heat-sensitive and easily crystallizing materials. Jacketed pipelines are commonly used for insulation and heating. They consist of an inner and an outer pipe. The material is transported through the inner pipe, while hot water, steam, or heat transfer oil is typically circulated in the outer pipe to maintain the temperature of the material within the inner pipe. Due to the jacketed design, the device requires a certain level of sealing and water pressure resistance. Existing technologies do not adequately address the sealing of the transition connections at the pipe ends of these jacketed pipelines, leading to potential leakage of the heat transfer medium and affecting the insulation effect. To address this technological gap, the inventors of this utility model propose a silicone tube jacketed thermostatic device. This device uses hydraulic oil seals at both pipe ends, and the inner pipe uses thermally stable silicone tubing. This design ensures that the pipeline provides jacketed heating and insulation functions while also guaranteeing the sealing of both pipe ends and water pressure resistance, preventing heat transfer medium leakage. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a silicone tube jacket constant temperature device, which uses hydraulic oil seal rings at both ends of the tube, so that while the pipeline has the functions of jacket heating and heat preservation, it also ensures good sealing performance and water pressure resistance at both ends of the tube, and prevents heat medium leakage.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A silicone tube jacketed thermostatic device includes a tube body and tube heads disposed at both ends of the tube body. The tube body comprises a copper tube and an insulation layer wrapped around the copper tube. The tube body also includes a silicone tube inside the copper tube and a heat transfer medium cavity formed between the copper tube and the silicone tube. Each tube head includes two hydraulic oil seal rings stacked together. The inner diameter of the hydraulic oil seal ring matches the diameter of the silicone tube. The silicone tube passes through the hydraulic oil seal ring and is tightly fitted to it.
[0006] Furthermore, the aforementioned silicone tube jacketed constant temperature device is characterized in that the inner diameter of the hydraulic oil seal ring matches the diameter of the silicone tube, the silicone tube passes through the hydraulic oil seal ring and can fit tightly with the hydraulic oil seal ring, the heat medium cavity between the silicone tube and the copper tube is used to introduce heat medium, the heat medium enters the heat medium cavity between the silicone tube and the copper tube from the heat medium inlet at one end of the copper tube, and then flows out from the heat medium outlet at the other end of the copper tube.
[0007] Furthermore, the silicone tube clamp constant temperature device is characterized in that the hydraulic oil seal is made of polyurethane, and two hydraulic oil seals are stacked at the tube end.
[0008] Furthermore, the aforementioned silicone tube jacket constant temperature device is characterized in that the insulation layer is made of insulation cotton.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] This utility model provides a silicone tube jacketed thermostatic device, in which two hydraulic oil seal rings are stacked inside the tube head. The inner diameter of the hydraulic oil seal rings matches the diameter of the silicone tube. The silicone tube can pass through the hydraulic oil seal rings and fit tightly against them, preventing the heat medium from overflowing from the heat medium cavity. This achieves a better heat preservation effect, so that while the pipeline has the functions of jacketed heating and heat preservation, it also ensures good sealing performance and water pressure resistance at both ends of the tube head, preventing heat medium leakage.

Obviously, the embodiments described below are only some embodiments of this utility model, not all embodiments. Based on this embodiment, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0015] like Figure 1As shown, a silicone tube jacketed thermostatic device includes a tube body and tube heads 5 disposed at both ends of the tube body. The tube body includes a copper tube 1 and an insulation layer 2 wrapped around the copper tube. The tube body includes a silicone tube 3 inside the copper tube 1 and a heat medium cavity 4 formed between the copper tube 1 and the silicone tube 3. The diameter of the silicone tube 3 is smaller than the inner diameter of the copper tube 1. Two hydraulic oil seal rings 6 are stacked inside the tube head 5. The two hydraulic oil seal rings 6 are used in a stacked manner. The silicone tube 3 passes through the seal ring 6 and its diameter matches the inner diameter of the hydraulic oil seal ring 6. The silicone tube 3 and the hydraulic oil seal ring 6 are tightly fitted. The heat medium cavity 4 between the silicone tube 3 and the copper tube 1 is used to introduce heat medium. The heat medium enters the heat medium cavity 4 between the silicone tube 3 and the copper tube 1 from the heat medium inlet 7 at one end of the copper tube 1, and then flows out from the heat medium outlet 8 at the other end of the copper tube 1. The hydraulic oil seal ring 6 is made of polyurethane, and the insulation layer 2 is made of insulation cotton. Figure 2 This is a cross-sectional view of the hydraulic oil seal 6 of this utility model. The hydraulic oil seal 6 is made of polyurethane, which is stable and durable.
[0016] The specific process is as follows: This utility model is used in the preparation of diclofenac sodium sustained-release tablets for the heat-sensitive and easily crystallizing material cetyl alcohol (C 16 H 34 For the delivery of Cetyl alcohol (C), after the device is assembled, 60°C hot water is introduced into the heat medium inlet 7. The hot water flows through the heat medium cavity 4 and out from the heat medium outlet 8. The recovered hot water is reheated to 60°C and introduced back into the heat medium inlet 7, and the cycle repeats. In addition, the insulation layer 2 made of heat insulation cotton wraps around the copper pipe 1, so that the temperature inside the copper pipe 1 is kept stable at 60°C. Then, the peristaltic pump is turned on to deliver the material into the silicone tube 3. 16 H 34 O) is kept in a liquid state at 60°C inside the silicone tube 3, avoiding the formation of cetyl alcohol (C 16 H 34 O) Production safety hazards caused by crystallization blockage. Two hydraulic oil seal rings 6 are placed in the pipe ends 5 respectively. The silicone tube 3 passes through the seal ring 6 and its diameter matches the inner diameter of the hydraulic oil seal ring 6. It is also tightly fitted with the hydraulic oil seal ring 6. Due to the characteristics of the hydraulic oil seal ring 6, it can resist the pressure of hot water (≤0.1MPa) and prevent hot water from overflowing from the heat medium cavity 4, thus achieving a better heat preservation effect.
