Description

Technical Field

[0001] This application relates to the field of solvent recovery equipment technology, and more specifically, to an organic solvent recovery device. Background Technology

[0002] Industrial production generates a large amount of waste solvents, which contain organic solvents with recycling value. Existing methods for recycling organic solvents mainly include distillation catalysis, adsorption recovery, microbial treatment, and low-temperature plasma treatment. Among these, distillation catalysis is suitable for treating high-concentration organic solvents. It involves adding a catalyst to high-concentration waste solvents and heating the waste solvent by distillation to generate vapor. The organic solvents are then obtained by condensing the vapors.

[0003] Existing distillation recovery equipment often has unsatisfactory vapor collection effects during the distillation process. Due to the varying concentrations and compositions of organic solvents in the waste solvent, and the different boiling points of various organic solvents, the vapor condensation rates of different solvents also differ, resulting in low recovery efficiency. Therefore, a catalyst needs to be added. However, in the later stages of distillation, the waste solvent produces excessive solid waste residue after being catalyzed. The waste residue adheres to the catalyst, affecting the catalytic interaction between the catalyst and the waste solvent, leading to a decrease in the efficiency of the catalytic reaction and a decline in the overall recovery efficiency.

[0004] Therefore, we propose an organic solvent recovery device to solve the existing problems. Utility Model Content

[0029] like Figures 1 to 5 As shown, an organic solvent recovery device includes a support 2, on which a housing 1 is mounted. The housing 1 has a cooling tank 11 and a distillation tank 12 arranged side-by-side. The cooling tank 11 contains a condenser pipe 111. The distillation tank 12 contains a vessel 5. A sealing assembly 6 is mounted on the top of the vessel 5. A stirring motor 61 is mounted above the sealing assembly 6. The output end of the stirring motor 61 passes through the sealing assembly 6 and is connected to a stirring shaft 66. The stirring shaft 66 drives a suction assembly and a stirring paddle 661 along its axis from top to bottom. One end of the suction assembly passes through the side wall of the vessel 5 and communicates with the condenser pipe 111. A tilting motor 4 is mounted on the support 2 and is driven through the support 2 and connected to the housing 1. During use, [the device is used to] [connect the cooling tank 111 to the distillation tank 1]. The distillation tank 12 heats the tank 5, causing the waste solvent inside the tank 5 to generate vapor. The cooling tank 11 has a built-in condenser 111 for cooling the vapor. The top of the tank 5 has a sealing assembly 6 for sealing the tank 5. A stirring motor 61 is installed on the sealing assembly 6. The motor output end passes through the sealing assembly 6 and is connected to the stirring shaft 66. A suction assembly and a stirring paddle 661 are connected from top to bottom on the shaft. One end of the suction assembly is connected to the condenser 111 for collecting vapor and transporting it to the condenser 111. A tilting motor 4 is installed on the support 2. The motor passes through the support 2 and is connected to the tank 1 for driving the tank 1 to tilt. After the distillation recovery is completed, the tank 5 is cleaned to remove the waste residue generated after the reaction in the tank 5.

[0030] Furthermore, a heat-conducting agent 121 and a heating component are filled between the tank 5 and the distillation tank 12, and a coolant is filled between the cooling tank 11 and the condenser tube 111. A solvent outlet 112 connected to the condenser tube 111 is installed at the bottom of the cooling tank 11. A pressure gauge 7 connected to the condenser tube 111 is installed on the cooling tank 11. In use, the heat-conducting agent 121 and the heating component are filled between the tank 5 and the distillation tank 12. The heating component heats the tank 5 and the internal solvent and catalyst. The heat-conducting agent 121 ensures the heat transfer effect and promotes the evaporation and vaporization of the solvent. The coolant between the cooling tank 11 and the condenser tube 111 enhances the cooling effect of the condenser tube 111. The solvent outlet 112 at the bottom of the cooling tank 11 is connected to the condenser tube 111 and is used to discharge the condensed solvent. The pressure gauge 7 on the cooling tank 11 monitors the pressure inside the condenser tube 111.

[0031] Furthermore, the sealing assembly 6 is an end cap 63 that is detachably covered on the top of the tank 5. The suction assembly includes a turbine shroud 64. One side of the top of the turbine shroud 64 is fixedly connected to the bottom of the end cap 63. One end of the bottom of the turbine shroud 64 is provided with an air inlet 642. The side end of the turbine shroud 64 is provided with a second connecting pipe 641 that connects to the air inlet 642. A turbine fan 65 is installed inside the turbine shroud 64. When in use, the stirring shaft 66 rotates, which drives the turbine fan 65 to rotate, generating negative pressure. This causes the vapor in the tank 5 to be sucked into the turbine shroud 64 of the suction assembly through the air inlet 642 and the second connecting pipe 641, and then sent to the condenser pipe 111 for cooling through the second connecting pipe 641 on the side end of the turbine shroud 64.

[0032] Furthermore, a first connecting pipe 51 is provided on the side wall of the tank body 5, and a second connecting pipe 641 is detachably connected to one end of the first connecting pipe 51 located inside the tank body 5. The other end of the first connecting pipe 51 passes through the tank body 5 and is connected to the condenser pipe 111, which facilitates disassembly and maintenance during use.

[0033] Furthermore, the stirring shaft 66 passes through the turbine fan 65 and is driven by the turbine fan 65. In use, when the stirring motor 61 drives the stirring shaft 66 to rotate, the turbine fan 65 rotates accordingly. The turbine fan 65 structure pushes and draws the organic solvent vapor generated by distillation heating in the tank 5, thereby drawing the vapor out of the tank 5 and into the subsequent condensation stage.

[0034] Furthermore, one end of the stirring paddle 661 is fixedly connected to the stirring shaft 66. The stirring paddle 661 extends spirally downward along the shaft of the stirring shaft 66. During use, the stirring shaft 66 rotates, and the paddle stirs the solvent in the tank, so that the solvent, the waste residue precipitated after heating, and the catalyst are fully mixed, so that the catalyst and the waste solvent are fully contacted and uniformly heated, thereby improving the evaporation efficiency. Moreover, the spiral structure of the propeller can stir the solvent at different liquid levels.

[0035] Furthermore, multiple equidistant connecting rings 62 are installed on the end cap 63. In use, the connecting rings 62 are gripped and positioned by a disassembly tool, enabling quick disassembly and assembly of the end cap 63, which facilitates internal cleaning, maintenance, and component replacement of the tank body 5.

[0036] Furthermore, rotating shafts 41 are fixedly installed at both ends of the housing 1. The rotating shafts 41 are rotatably connected to the bracket 2. The other end of the rotating shafts 41 passes through the bracket 2 and is connected to the output end of the tilting motor 4. A support connection assembly 3 is also provided between the bracket 2 and the housing 1. In use, the rotating shafts 41 are driven to rotate by the tilting motor 4, thereby causing the housing 1 to rotate around the bracket 2, realizing the tilting action of the housing 1. This facilitates the pouring of the waste residue remaining in the tank 5 after distillation and the cleaning of the inside of the tank 5.

[0037] Furthermore, the support connection assembly 3 includes a first cylinder 31 and a second cylinder 32 arranged perpendicularly to each other. One end of the first cylinder 31 and the second cylinder 32 are fixedly connected to the bracket 2. The output end of the first cylinder 31 is fixed on the front side wall of the box 1, and the output end of the second cylinder 32 is fixed on the rear side wall of the box 1. In use, during the tilting or resetting process of the box 1, the first cylinder 31 and the second cylinder 32 provide stable support force for the box 1 through telescopic adjustment, so that the box 1 can stay stably at any tilting angle and avoid shaking or accidental tilting due to gravity.

[0038] Furthermore, a control component 8 is installed at the front end of the housing 1. The control component 8 is electrically connected to the pressure gauge 7, the tilting motor 4, and the stirring motor 61. During use, the control component 8 can be used to set and adjust various parameters of the equipment to achieve automated and precise control of the organic solvent recovery device.

[0039] The working principle of this invention is as follows: In use, waste solvent and catalyst are added to tank 5. The heating component is activated via control component 8 to heat tank 5, causing the waste solvent inside to be heated and generate steam under the action of the catalyst. Simultaneously, stirring motor 61 drives stirring shaft 66 to rotate, and stirring paddle 661 stirs the solvent inside tank 5, ensuring thorough mixing of the waste solvent, the waste residue precipitated after heating, and the catalyst. This ensures that the catalyst and waste solvent are always in full contact and uniformly heated during the recovery process, improving steam generation efficiency. After steam is generated, stirring shaft 66 drives turbine fan 65 to rotate, generating negative pressure. This causes the steam inside tank 5 to be drawn into the turbine cover 6 of the suction component through air inlet 642 and second connecting pipe 641. In step 4, the solvent is fed into the condenser tube 111 through the second connecting pipe 641 on the side of the turbine cover 64. It is cooled by the coolant outside the condenser tube 111 and thus liquefied and condensed. The condensed solvent is discharged through the solvent outlet 112. After the distillation recovery is completed, the tilting motor 4 is started by the control component 8. The tilting motor 4 drives the rotating shaft 41 to rotate, thereby causing the tank 1 to rotate around the support 2, so as to tilt the tank 1, which facilitates the dumping of the waste residue remaining in the tank 5 after distillation and cleaning the inside of the tank 5. During the tilting or resetting of the tank 1, the first cylinder 31 and the second cylinder 32 provide stable support force for the tank 1 through extension and retraction adjustment, so that the tank 1 can stay stably at any tilting angle and avoid shaking or accidental tilting due to gravity.

[0040] The above-described specific embodiments are merely preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
