Description

Technical Field

[0001] This utility model relates to the field of plasticizer production technology, specifically a distillation apparatus for producing rubber plasticizers. Background Technology

[0002] Rubber plasticizers are reagents. Plasticizing rubber refers to adding certain substances to rubber that reduce the intermolecular forces, thereby lowering the glass transition temperature and enhancing its plasticity and flowability. This facilitates molding operations such as calendering and extrusion. Simultaneously, it can improve certain physical and mechanical properties of vulcanized rubber, such as reducing hardness and tensile stress, imparting higher elasticity and lower heat generation, and improving cold resistance. In the production process, some companies obtain plasticizers through the esterification reaction of acids and alcohols. Because the products obtained from this type of esterification reaction contain a certain amount of intermediates and many impurities, further purification is required through distillation.

[0003] Chinese patent application number 202122629026.0 discloses a distillation apparatus for producing rubber plasticizers, including a base, a fixed frame connected to the top center of the base, a distillation tank connected to the upper end of the fixed frame, an electric heater embedded in the bottom of the inner cavity of the distillation tank, a cover plate on the top of the distillation tank, a condenser connected to the top left side of the cover plate, a condenser tube inside the condenser tube, a guide tube connected to the right end of the condenser tube, a distillation suction cup connected to the end of the guide tube extending into the distillation tank, a receiver connected to the end of the condenser tube passing through the cover plate, a liquid collection tank below the receiver, and a control panel on the outer wall of the base. This distillation apparatus for producing rubber plasticizers is reasonably designed, which is conducive to improving the distillation preparation efficiency of rubber plasticizers, facilitating the inspection and maintenance of components, and making it convenient to clean the residue inside the distillation tank, making it practical and easy to use.

[0004] The distillation apparatus for producing rubber plasticizers still has some shortcomings in actual use, such as low condensation efficiency and high energy consumption. During the condensation process, the temperature of the cooling medium that is in direct contact with the condenser tube will rise, the contact time between the circulating cooling medium and the condenser tube is short, and the utilization rate of the cooling medium is low. Utility Model Content

[0005] The purpose of this invention is to provide a distillation apparatus for producing rubber plasticizers, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a distillation apparatus for producing rubber plasticizers, comprising a distillation component, wherein a condensation component is provided at the top of the distillation component; The condensation assembly includes a condensation box, which has an inner condensation chamber and an outer condensation chamber. The inner condensation chamber is located in the middle of the outer condensation chamber, and the outer condensation chamber surrounds the outer side of the inner condensation chamber. Multiple baffle heat-conducting plates are staggered from top to bottom inside the condensation box. Multiple condensation tubes are provided inside the condensation box. One end of each of the multiple condensation tubes is connected to a flow guide bend, and the other end of each of the multiple condensation tubes extends to the other side of the condensation box.

[0007] Preferably, the distillation assembly includes a machine base, a distillation tank is fixedly installed on one side of the top surface of the machine base, a distillation chamber is provided inside the distillation tank, and a condenser is fixedly installed on one side of the top surface of the machine base.

[0008] Preferably, an electric heater is provided at the bottom of the distillation tank, and a cap is threaded onto the top of the distillation tank.

[0009] Preferably, one end of each of the multiple flow guide bends extends into the distillation chamber, and a distillation suction cup is fixedly connected to the end of the flow guide bend that extends into the distillation chamber.

[0010] Preferably, the plurality of condenser tubes are arranged in a repeatedly bent manner, and the plurality of condenser tubes all pass through the body of the baffle heat conduction plate.

[0011] Preferably, a No. 1 water inlet pipe is provided on one side of the top of the outer condensing chamber, a No. 1 water outlet pipe is provided on the other side of the bottom of the outer condensing chamber, and a No. 2 water inlet pipe and a No. 2 water outlet pipe are respectively provided on the same side of the top and bottom of the inner condensing chamber.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This distillation apparatus for rubber plasticizer production utilizes a three-stage temperature gradient created by inner and outer dual condensing chambers combined with baffled heat-conducting plates. This effectively enhances the steam condensation rate, resulting in better condensation performance compared to traditional single-chamber structures. Simultaneously, the cooling media entering both the inner and outer condensing chambers are baffled by the heat-conducting plates. Condensation occurs first in the inner condensing chamber. During liquefaction, the steam dissipates heat, causing the temperature of the cooling media within the inner condensing chamber to rise. To prevent a decrease in condensation efficiency, the heat is transferred to the outer condensing chamber via the baffled heat-conducting plates, where the cooling media further assists in cooling. This prevents the temperature of the cooling media in the inner condensing chamber from rising too rapidly, which could negatively impact condensation. Furthermore, the dual-cycle cooling system can maintain 60% of the basic condensation capacity even in the event of a single-chamber failure, enhancing its functionality. Attached Figure Description

[0015] 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.

[0016] like Figures 1-4 As shown, this utility model provides a technical solution: including a distillation assembly 1, wherein a condensation assembly 2 is provided at the top of the distillation assembly 1; The condensation assembly 2 includes a condensation box 201, which has an inner condensation chamber 203 and an outer condensation chamber 202. The inner condensation chamber 203 is located in the middle of the outer condensation chamber 202, and the outer condensation chamber 202 surrounds the outer side of the inner condensation chamber 203. Multiple baffle heat-conducting plates 204 are staggered from top to bottom inside the condensation box 201. Multiple condensing pipes 205 are provided inside the condensation box 201. One end of each of the multiple condensing pipes 205 is connected to a flow-guiding bend 206, and the other end of each of the multiple condensing pipes 205 extends to the other side of the condensation box 201. The innovative design of the inner condensation chamber 203 and the outer double condensation chamber 203 guides the cooling medium to form a baffle through the baffle heat-conducting plates 204, thereby increasing the flow time of the cooling medium and improving the heat exchange efficiency within a limited space.

[0017] In this embodiment, the distillation assembly 1 includes a machine base 101, a distillation tank 102 is fixedly installed on one side of the top surface of the machine base 101, a distillation chamber 103 is provided inside the distillation tank 102, and a condenser 201 is fixedly installed on one side of the top surface of the machine base 101.

[0018] Meanwhile, an electric heater 104 is provided at the bottom of the distillation tank 102, and a cap 105 is threaded onto the top of the distillation tank 102 to achieve a seal.

[0019] One end of each of the multiple flow guide bends 206 extends into the distillation chamber 103, and a distillation suction cup 207 is fixedly connected to the end of the flow guide bend 206 that extends into the distillation chamber 103.

[0020] The multiple condenser tubes 205 are arranged in a repeatedly bent manner, and all of the multiple condenser tubes 205 pass through the body of the baffle heat conduction plate 204. The condenser tubes 205 are arranged in a serpentine manner and pass through the baffle heat conduction plate 204.

[0021] The outer condensing chamber 202 has a first water inlet pipe 208 on one side of its top and a first water outlet pipe 209 on the other side of its bottom. The inner condensing chamber 203 has a second water inlet pipe 210 and a second water outlet pipe 211 on the same side of its top and bottom, respectively. The cooling water circulates in both chambers. The cooling medium is introduced through the first water inlet pipe 208 and the first water outlet pipe 209 and flows out through the second water inlet pipe 210 and the second water outlet pipe 211.

[0022] During use, the electric heater 104 heats up to 180-220℃, and the steam enters the condenser 205 through the distillation suction cup 207 and the guide bend 206. Condensation stage: 10℃ low-temperature water is simultaneously introduced into the outer condensing chamber 202 and the inner condensing chamber 203. Specifically, the cooling medium is introduced through the first inlet pipe 208 and the first outlet pipe 209, and flows out through the second inlet pipe 210 and the second outlet pipe 211. The cooling medium entering the inner condensing chamber 203 and the outer condensing chamber 202 will form baffles under the action of the baffle heat conduction plate 204. Condensation first occurs in the inner condensing chamber 203. During the liquefaction process, the steam will dissipate heat, and the temperature of the cooling medium in the inner condensing chamber 203 will rise. In order to avoid the condensation effect being reduced, the heat can be conducted to the outer condensing chamber 202 through the baffle heat conduction plate 204, and the cooling medium in the outer condensing chamber 202 will assist in the cooling. Collection stage: The condensate is introduced into an external collection tank through the receiver. The collection tank is connected to one end of the condenser tube 205. The evaporated gas becomes distilled liquid after passing through the condenser tube 205, and then is introduced into the collection tank through the condenser tube 205 for collection.

[0023] In summary, this distillation apparatus for rubber plasticizer production forms a three-stage temperature gradient through inner and outer dual condensing chambers combined with baffle heat-conducting plates 204, effectively improving the steam condensation rate and achieving better condensation performance than traditional single-chamber structures. Simultaneously, the cooling media entering both the inner condensing chamber 203 and the outer condensing chamber 202 are baffled by the baffle heat-conducting plates 204, with condensation occurring first in the inner condensing chamber 203. During liquefaction, the steam dissipates heat, causing the temperature of the cooling medium in the inner condensing chamber 202 to rise. To prevent a decrease in condensation efficiency, the heat is transferred to the outer condensing chamber 202 via the baffle heat-conducting plates 204, and the cooling medium in the outer condensing chamber 202 assists in cooling, preventing the temperature of the cold-cooling medium in the inner condensing chamber 202 from rising too rapidly and affecting the condensation effect. Furthermore, the dual-cycle cooling system can maintain 60% of the basic condensation capacity in the event of a single-chamber failure, enhancing its functionality.
