Description

Technical Field

[0001] This utility model relates to the field of rubber additive production technology, specifically to an environmentally friendly condensation reflux device for distillation and purification of rubber additives. Background Technology

[0002] In the production process of environmentally friendly rubber additives, distillation purification is a crucial step, effectively removing impurities and improving the purity and quality of the rubber additives. However, existing condensation reflux devices suffer from problems such as poor condensation effect, low coolant utilization rate, and difficulty in accurately collecting purified products when distilling and purifying environmentally friendly rubber additives. This not only affects the purification efficiency and quality of rubber additives but may also lead to energy waste, failing to meet the requirements of environmentally friendly production. Therefore, an improved condensation reflux device is urgently needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an environmentally friendly condensation reflux device for the distillation and purification of rubber additives, which has the advantage of good condensation effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a condensation reflux device for the distillation and purification of environmentally friendly rubber additives, comprising a distillation tank, a spiral condenser tube connected to the top of the distillation tank, a collection box connected to the right end of the spiral condenser tube, a collection tank located on the right side of the collection box, a cooling jacket sleeved around the spiral condenser tube, an inlet pipe connected to the left side of the top of the cooling jacket, an inner sheath fitted inside the cooling jacket and located inside the spiral condenser tube, the inner sheath and the spiral condenser tube forming a double-layer structure, an outlet pipe connected to the right side of the cooling jacket, and the lower right end of the outlet pipe connected to the top of the collection tank.

[0005] As a preferred embodiment, a return pipe is connected above one end of the outlet pipe, a return valve is movably installed at the upper end of the return pipe, and the other end of the return pipe is connected to the inlet pipe at the top of the cooling jacket.

[0006] As a preferred embodiment, a regulating valve is movably installed on the surface of one end of the outlet pipe, and a sealing cap is snapped onto the right side of the top of the collection tank. The bottom of the sealing cap is connected to the inner wall of the processing pipe at the top of the collection tank through a sealing gasket.

[0007] As a preferred embodiment, both ends of the cooling jacket are fixedly equipped with sealing baffles, and the interior of the sealing baffles is also connected to the inner sheath.

[0008] As a preferred embodiment, the cooling jacket has a hollow interior, and the coolant flowing inside the inlet pipe is located inside the hollow tank.

[0009] As a preferred embodiment, the inner wall of the inner sheath is provided with a number of protrusions, which are distributed in a spiral shape.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model significantly increases the flow path and residence time of steam within the condenser tube through the design of the spiral condenser tube. As the steam flows through the spiral channel, its contact time with the cooling medium is prolonged, allowing for more thorough heat exchange and effectively improving condensation efficiency. This enables the environmentally friendly rubber additive steam to be cooled into liquid more quickly and thoroughly, providing a good foundation for subsequent purification and collection. The cooling jacket provides a continuous and stable cooling environment for the spiral condenser tube. Coolant is continuously injected through the inlet pipe, flowing within the jacket and absorbing heat from the steam within the spiral condenser tube. This circulating cooling method ensures the uniformity and stability of the cooling effect, guaranteeing effective cooling of the steam throughout the entire condensation process.

[0012] 2. This utility model utilizes the cooling liquid to absorb the heat of the steam in the spiral condenser within the cooling jacket, and then flows out through the outlet pipe. Part of the cooling liquid can return to the inlet pipe through the return pipe and participate in the cooling cycle again. This design significantly improves the utilization rate of the cooling liquid, reduces the amount of cooling liquid to be replenished, and thus reduces the cost caused by frequent addition of cooling liquid. For long-term distillation and purification processes, this design can effectively save production costs. Attached Figure Description

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0019] Please see Figure 1 As shown, this utility model provides a condensation reflux device for the distillation and purification of environmentally friendly rubber additives, including a distillation tank 1, a spiral condenser tube 2 connected to the top of the distillation tank 1, a collection box 3 connected to the right end of the spiral condenser tube 2, a collection tank 8 set on the right side of the collection box 3, a cooling jacket 4 sleeved on the outside of the spiral condenser tube 2, a liquid inlet pipe 10 connected to the left side of the top of the cooling jacket 4, an inner sheath 13 fitted inside the cooling jacket 4 and located inside the spiral condenser tube 2, the inner sheath 13 and the spiral condenser tube 2 forming a double-layer structure, a liquid outlet pipe 11 connected to the right side of the cooling jacket 4, and the lower right end of the liquid outlet pipe 11 connected to the top of the collection tank 8.

[0020] The design of the spiral condenser tube 2 in this technical solution greatly increases the flow path and residence time of steam within the condenser tube. As the steam flows through the spiral channel, its contact time with the cooling medium is extended, allowing for more thorough heat exchange and effectively improving condensation efficiency. This enables the environmentally friendly rubber additive steam to be cooled into liquid more quickly and thoroughly, providing a good foundation for subsequent purification and collection. The cooling jacket 4 provides a continuous and stable cooling environment for the spiral condenser tube 2. Coolant is continuously injected through the inlet pipe 10, flowing within the jacket and absorbing the heat from the steam within the spiral condenser tube 2. This circulating cooling method ensures the uniformity and stability of the cooling effect, guaranteeing effective cooling of the steam throughout the entire condensation process. Example

[0021] Based on Embodiment 1, this utility model is as follows: Figure 3 As shown, a return pipe 6 is connected to one end of the outlet pipe 11, a return valve 7 is movably installed at the upper end of the return pipe 6, and the other end of the return pipe 6 is connected to the inlet pipe 10 at the top of the cooling jacket 4.

[0022] Adopting such Figure 1The technical solution shown allows the coolant to absorb heat from the steam in the spiral condenser 2 within the cooling jacket 4 and then flow out from the outlet pipe 11. Part of the coolant can return to the inlet pipe 10 through the return pipe 6 and participate in the cooling cycle again. This design significantly improves the utilization rate of the coolant and reduces the amount of coolant replenishment, thereby reducing the cost caused by frequent coolant additions. For long-term distillation and purification processes, this design can effectively save production costs.

[0023] Secondly, in the technical solution, a regulating valve 9 is movably installed on the surface of one end of the liquid outlet pipe 11, and a sealing cover 12 is snapped onto the right side of the top of the collection tank 8. The bottom of the sealing cover 12 is connected to the inner wall of the processing pipe at the top of the collection tank 8 through a sealing gasket. Both ends of the cooling jacket 4 are fixedly installed with sealing baffles 5, and the inside of the sealing baffles 5 is also connected to the inner sheath 13.

[0024] Its adoption is as follows Figure 1 The technical solution shown has a regulating valve 9 installed on the outlet pipe 11, which can precisely regulate the flow rate of coolant. In the process of distillation and purification of environmentally friendly rubber additives, the cooling intensity requirements are different at different stages. When the amount of steam generated in the distillation tank 1 is large and a stronger cooling effect is required, the opening of the regulating valve 9 can be increased to increase the flow rate of coolant and enhance the cooling capacity. Conversely, when the amount of steam is small, the opening can be reduced to decrease the flow rate of coolant and avoid over-cooling, thereby achieving fine control of the cooling process and improving the efficiency and quality of distillation and purification. Example

[0025] This utility model is as follows Figures 1-3 As shown, the cooling jacket 4 has a hollow interior, and the coolant flowing inside the inlet pipe 10 is located inside the hollow groove; the inner wall of the inner sheath 13 is provided with several protrusions, which are distributed in a spiral shape.

[0026] By adopting the above technical solution, the hollow design inside the cooling jacket 4 provides sufficient flow space for the coolant. After the coolant flows into the hollow tank from the inlet pipe 10, it can flow freely and evenly in the jacket without flow obstruction or local eddies due to the narrow space. This helps the coolant to fully absorb the heat of the steam in the spiral condenser 2 and ensures the efficient operation of the cooling process.

[0027] The working principle of this utility model is as follows: the environmentally friendly rubber additive to be purified is distilled in the distillation tank 1, and the generated vapor rises into the spiral condenser 2. The coolant enters the cooling jacket 4 through the liquid inlet pipe 10 to cool the vapor in the spiral condenser 2. Since the inner sheath 13 and the spiral condenser 2 form a double-layer structure, and the spiral protrusions on the inner wall of the inner sheath 13 increase the contact area between the vapor and the inner sheath 13, the condensation effect is improved. After the vapor is cooled into liquid in the spiral condenser 2, it flows into the collection tank 3. In the liquid outlet pipe 11, a portion of the coolant can be returned to the cooling jacket 4 through the return pipe 6 and the return valve 7 for recirculation and cooling. After the coolant completes heat exchange in the cooling jacket 4, it is discharged through the liquid outlet pipe 11 and flows into the collection tank 8.
