Description

Technical Field

[0001] This utility model relates to the field of resin processing technology, and in particular to a waste heat recovery device for resin processing. Background Technology

[0002] Resin processing has wide applications in modern industry, covering multiple fields such as plastic products, composite materials, coatings, and adhesives. With the continuous growth of market demand for resin products, the production scale of resin processing enterprises is also expanding. However, resin processing typically consumes a large amount of energy. For example, in the stages of resin synthesis and molding, heating is required to bring the resin to specific process temperatures to ensure product quality and performance.

[0003] A typical waste heat recovery device for resin processing consists of a conversion chamber, a conveying system, and a waste heat recovery unit. The conversion chamber uses coolant to perform heat conversion with high-temperature resin, initially absorbing and converting the heat generated during resin processing. The conveying system uses pipelines to transport coolant carrying waste heat to the waste heat recovery unit, which then transfers the waste heat to the resin to be heated, achieving secondary utilization of heat.

[0004] In some of the aforementioned technologies, the heat conversion efficiency of high-temperature resin materials is low due to unreasonable structural design or heat exchange methods. This results in insufficient recovery of waste heat generated during resin processing, leading to energy waste. Furthermore, an excessive pursuit of sufficient heat conversion causes excessive heat loss from the resin material within the pipeline, resulting in a significant temperature drop and ultimately condensation of the resin material within the pipeline. This not only affects the normal transport of materials within the pipeline but also increases equipment maintenance costs and downtime, severely restricting the continuity and efficiency of resin processing production. Therefore, a waste heat recovery device for resin processing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a waste heat recovery device for resin processing, which aims to improve the problem that some existing devices have low heat conversion efficiency for high-temperature resin materials and are prone to resin material condensation in the pipeline due to excessive heat conversion.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A waste heat recovery device for resin processing includes a conversion outer tube, a connecting outer tube fixedly connected to the outside of the conversion outer tube, a recovery mechanism disposed inside the connecting outer tube, a liquid inlet fixedly connected to the outside of the conversion outer tube, a liquid outlet fixedly connected to the outside of the conversion outer tube, a feed inlet fixedly connected to the outside of the connecting outer tube, a conveying mechanism disposed outside the feed inlet, and a flow divider plate fixedly connected to the outside of the connecting outer tube. Multiple fine flow tubes are fixedly connected to the outside of the flow divider plate, and a coarse flow tube is fixedly connected to the outside of the flow divider plate. A connecting cavity tube is fixedly connected to the other end of the coarse flow tube, and a discharge port is fixedly connected to the other end of the connecting cavity tube. A support assembly is fixedly connected to the outside of the conversion outer tube. As a further description of the above technical solution: The conveying mechanism includes a transmission pipe, one end of which is fixedly connected to the outside of the feed inlet, a circulation pipe is fixedly connected to the outside of the liquid inlet, a snap-fit ​​plate is fixedly connected to the outside of the transmission pipe, a base frame is fixedly connected to the bottom of the snap-fit ​​plate, and a connecting plate is fixedly connected to the outside of the transmission pipe. As a further description of the above technical solution: The other end of the transmission tube is fixedly connected to a processing tube, and a waste heat recovery device is installed on the outside of the processing tube. The other end of the processing tube is fixedly connected to a connection port. As a further description of the above technical solution: The other end of the first circulation pipe is fixedly connected to a recovery pipe, and the other end of the recovery pipe is fixedly connected to a second circulation pipe. As a further description of the above technical solution: The outside of the recovery pipe is installed inside the waste heat recovery unit, and the other end of the second circulation pipe is fixedly connected to the outside of the liquid outlet. As a further description of the above technical solution: The support assembly includes an arc plate, which is fixedly connected to the outside of the conversion outer tube, and a support frame is fixedly connected to the outside of the arc plate. As a further description of the above technical solution: The inside of the snap-fit ​​plate is fixedly connected to the outside of the first circulation tube, and the inside of the connecting plate is fixedly connected to the outside of the first circulation tube. As a further description of the above technical solution: The outlet is fixedly connected to the inside of the conversion outer tube, and the other end of the coarse flow tube is fixedly connected to the outside of the connecting cavity tube.

[0007] This utility model has the following beneficial effects: 1. In this utility model, by using a flow divider to divert the material to the fine flow tube and the coarse flow tube, the contact area with the conversion outer tube is increased, the heat exchange efficiency is improved, and finally the material flows out through the combined cavity tube, thereby realizing efficient heat conversion of high temperature resin material and preventing the problem of condensation in the pipe due to excessive heat conversion.

[0008] 2. In this utility model, after the coolant absorbs waste heat in the conversion outer pipe, it completes circulation through the outlet, circulation pipe two, recovery pipe, and circulation pipe one. The waste heat transferred in the recovery pipe heats the resin material in the processing pipe, forming high-temperature resin material in conjunction with the heating instrument. The high-temperature resin material enters the connecting outer pipe through the transmission pipe, thereby realizing the recovery and reuse of waste heat to form a circulation system, reducing the problems of low efficiency and insufficient waste heat recovery during operation.
