Description

Technical Field

[0001] The utility model relates to the technical field of hydrocarbon solvent waste liquid recovery, in particular to hydrocarbon solvent waste liquid recovery equipment. Background Art

[0002] Hydrocarbon solvent cleaning, that is, the cleaning process using hydrocarbon cleaning agents, is a cleaning technology widely used in the industrial field. Hydrocarbon cleaning agents are mainly composed of hydrocarbons composed of two elements, carbon and hydrogen. They are formulated by deep processing of crude oil and adding active solvents, solubilizers, stabilizers, etc. Hydrocarbon cleaning agents are non-polar petroleum fractions like most lubricating oils, rust-proof oils, and machining oils. According to the principle of like dissolves like, their effect in cleaning these mineral oils is better than halogenated hydrocarbons and water-based cleaning agents. Hydrocarbon cleaning agents can effectively dissolve organic dirt such as grease, wax, and glue, and separate them from the surface being cleaned. The boiling point of hydrocarbon cleaning agents is relatively high, generally above 150°C, so the volatile loss during use and storage is small, and the sealing requirements for packaging and equipment are very low. According to toxicological tests, the inhalation toxicity, oral toxicity, and skin contact toxicity of hydrocarbon cleaning agents are all low, and they are not carcinogenic, making them safer for cleaning operators.

[0003] However, after the existing hydrocarbon solvent cleaning is completed, the residual waste liquid needs to be recycled and reused. Common hydrocarbon cleaning machines use a distillation structure with complex pipelines, and their manufacturing precision requirements are high, which makes the cost and selling price of hydrocarbon cleaning machines high, making them difficult to popularize. Therefore, the utility model provides a hydrocarbon solvent waste liquid recovery device to meet the needs. Utility Model Content

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] In the above solution, this device utilizes a two-layer structure: an inner tank liner and an outer tank shell, with the interlayer between them used to hold the thermal oil.

[0019] The following is a detailed description of a hydrocarbon solvent waste liquid recovery device provided by the present invention in conjunction with the accompanying drawings and specific embodiments; at the same time, it is explained here that, in order to make the embodiments more detailed, the following embodiments are preferred embodiments, and for some well-known technologies, those skilled in the art may also adopt other alternative methods.

[0020] like Figures 1 to 3As shown, the embodiment of the present invention provides a hydrocarbon solvent waste liquid recovery device, including a frame 17, a tank body 10 is provided inside the frame 17, a cylinder head 1 is hinged on the top of the tank body 10, a tank shell 9 is provided outside the tank body 10, a sealing strip 8 is provided between the top of the tank body shell 9 and the cylinder head 1, an operation panel 11 is provided on one side of the frame 17, an electric control box 16 is provided inside the frame 17, a heat transfer oil injection pipe is provided outside the tank body shell 9, a heat transfer oil injection port threaded cover 7 is provided on the top of the heat transfer oil injection pipe, a waste residue discharge pipe is provided on one side of the bottom end of the tank body 10, a waste residue discharge threaded cover 12 is provided on one side of the waste residue discharge pipe, a steam outlet 2 is provided outside the tank body 10, a steam conduit is provided at the output end of the steam outlet 2, a steam temperature probe 4 is provided on the outside of the steam conduit, a steam connecting hose 3 is fixedly connected to the bottom of the steam conduit, a condenser 6 is fixedly connected to the interior of the frame 17, and a steam connection The output end of the hose 3 is fixedly connected to the input end of the condenser 6. The input end of the condenser 6 is provided with a new liquid flow outlet 15. A heat dissipation fan 5 is provided on one side of the frame 17. The heat dissipation fan 5 is located on one side of the condenser 6. A thermal oil heating pipe 18 is provided at the bottom of the tank shell 9. A thermal oil discharge ball valve 19 is provided on the outside of the thermal oil heating pipe 18. Open the thermal oil injection port threaded cover 7, and inject an appropriate amount of thermal oil (about 45 liters) into the interlayer between the tank shell 9 and the tank body liner 10. Then tighten the thermal oil injection port threaded cover 7 to ensure sealing. Open the cylinder head 1 and pour the dirty hydrocarbon solvent to be recycled into the tank body liner 10. Note that the liquid level should not exceed the steam outlet 2 to prevent steam overflow. Close the cylinder head 1 and tighten the screws above to ensure the sealing of the tank body liner 10 to prevent steam leakage. Start the heating button on the operation panel 11. The electrical control box 16 controls the thermal oil heating pipe 18 to start working, and the thermal oil temperature gradually rises. As needed, the maximum temperature of the thermal oil can be set to 200°C. As the temperature of the thermal oil rises, the hydrocarbon solvent in the tank liner 10 is heated by the oil bath. When the temperature reaches the boiling point of the hydrocarbon solvent (generally around 162°C), the solvent begins to boil and produce steam. The steam enters the steam conduit through the steam outlet 2. The steam temperature probe 4 monitors the steam temperature in real time to ensure the stability of the distillation process. After passing through the steam conduit, the steam enters the condenser 6 through the steam connecting hose 3 for cooling and condensation. In the condenser 6, the steam is cooled and condensed into liquid hydrocarbon solvent. The condensed solvent flows out of the new liquid outlet 15 and is collected for reuse. The heat dissipation fan 5 is located on one side of the condenser 6, providing the necessary cooling air for the condensation process and ensuring the condensation effect. After the recycling machine has cooled, the waste residue discharge threaded cover 12 is opened to remove the waste residue and dirty solutes remaining in the tank liner 10. These waste residues are usually organic dirt such as grease, wax, and glue dissolved during the cleaning process. After cleaning, the waste residue discharge threaded cover 12 is closed to prepare for the next recycling work. By heating with an oil bath and cooling with a condenser 6, efficient recycling of hydrocarbon solvent waste liquid is achieved.The recycling speed is fast and the efficiency is high, which can significantly reduce waste liquid discharge and environmental pollution. The recycling process does not require the use of large amounts of water resources, reducing wastewater discharge and energy consumption. At the same time, the recovered hydrocarbon solvent can be reused in the cleaning process, realizing the recycling of resources. The equipment structure is reasonably designed, and the operation panel 11 is clear and easy to understand. Operators only need simple training to get started, which reduces the difficulty of operation and labor costs. The equipment adopts a double-layer structure design, and the heat transfer oil and hydrocarbon solvent are heated separately, avoiding the burning, deterioration and safety hazards that may be caused by direct heating of the hydrocarbon solvent by the heating pipe. At the same time, the equipment is equipped with sealing devices such as sealing strips 8 and threaded covers, as well as an over-temperature and over-pressure protection system to ensure the sealing and safety of the equipment.

[0021] like Figures 1 to 3 As shown, the four corners of the bottom of the frame 17 are equipped with feet 13 and casters 14. During normal operation, the feet 13 support and stabilize the frame 17, ensuring that the equipment will not be displaced by vibration or external forces during heating, distillation, and condensation processes, thereby ensuring the stability and safety of the equipment. When the equipment needs to be moved or adjusted, the height of the feet 13 can be adjusted so that the casters 14 contact the ground or the workbench, allowing the frame 17 to be easily moved. This design makes it easier to transport the equipment between different workstations. During maintenance and cleaning, the height of the feet 13 and casters 14 can be adjusted to easily move the frame 17 to the appropriate location for operation, improving operational convenience and efficiency. The combination of the feet 13 and casters 14 achieves an excellent balance between stability and mobility. The equipment can be stably fixed in a designated location for operation while also being easily moved to other locations when needed, enhancing its flexibility and adaptability.

[0022] The working principle of the utility model is as follows: First, unscrew the threaded cap 7 of the thermal oil inlet and fill it with thermal oil (approximately 45 liters), then tighten the cap. Manually open the cylinder head 1 and pour in dirty hydrocarbon solvent (up to 120 liters) until the liquid level does not exceed the height of the steam outlet 2. Close the cylinder head 1 and tighten the six screws on it. The entire cleaning process is completed. Turn on the heating button and condenser 6 button on the operation panel 11, and the thermal oil heating pipe 18 begins to operate. The thermal oil temperature continues to rise (the maximum temperature of the thermal oil can be set to 200°C). The hydrocarbon solvent is heated by the oil bath. When the temperature reaches 162°C, the hydrocarbon solvent begins to boil. The pressurized vapor is continuously squeezed out of the steam outlet 2. Cooled by the condenser 6, it condenses and turns into clean hydrocarbon liquid, which flows out of the liquid outlet 15 again. A can of dirty hydrocarbon solvent can be evaporated in as little as two hours. After the recovery machine cools, open the waste residue discharge threaded cap 12 to remove the dirty solute, completing the recovery process.

[0023] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention; in order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
