Description

Technical Field

[0001] This utility model relates to the field of waste heat utilization of solvent recovery machines, and more specifically, to a waste heat utilization device for solvent recovery machines. Background Technology

[0002] Solvent recovery machines are widely used in many industrial production processes to recover various organic solvents, thereby reducing production costs and environmental pollution. However, traditional solvent recovery machines generate a large amount of waste heat during operation.

[0003] On the one hand, if this waste heat is not utilized, it will be wasted, which is not only a loss of energy, but also does not meet the current requirements of energy conservation and environmental protection. In today's increasingly energy-scarce world, how to effectively utilize these waste heat resources has become an important issue. On the other hand, many industrial production sites need additional heat sources to meet specific process requirements, such as heating water for cleaning and heating. If the waste heat generated by the solvent recovery machine can be used reasonably, the dependence on other energy sources can be reduced and energy costs can be lowered.

[0004] Therefore, it is necessary to redesign the waste heat recovery device of the solvent recovery machine to address the above-mentioned problems. Utility Model Content

The collection box 8 can collect the scraped impurities.

[0029] Two limiting holes 17 are symmetrically opened on both sides of the collection box 8, and the output ends of the two fixing devices abut against the corresponding limiting holes 17. A handle is fixedly installed on the outer wall of the collection box 8. The collection box 8 can collect impurities in the heat exchange tube 1.

[0030] Each fixing device includes a spring 22, which is fixedly installed on the inner side wall of the corresponding mounting groove 21. One end of the spring 22 is fixedly connected to a limiting rod 23, which is slidably engaged in the corresponding mounting groove 21.

Through the elastic properties of the spring 22, the spring 22 can drive the limiting rod 23 to remain abutting against the limiting hole 17.

[0031] The ventilation device includes a fixed shaft 10, which is rotatably mounted on one side of the filter plate 2. The output end of the synchronization component is fixedly connected to the outer wall of the fixed shaft 10. A fixed sleeve 14 is fixedly mounted on one end of the fixed shaft 10.

Then, the second synchronous wheel 12 can drive the fixed shaft 10 to rotate. Then, the fixed shaft 10 can drive the fixed sleeve 14 and the fan blade 15 to rotate. At this time, the solvent vapor can pass through the heat exchange tube 1 and be filtered through the filter plate 2 to be discharged to the outside. When the solvent vapor passes through the heat exchange tube 1, the heat in the vapor can be conducted to the water tank through the heat exchange tube 1 to heat the water in the tank.
