However, due to the contact with steam, the condensate contains residual heat. Sending this condensate, which is still warm, into the storage tank may result in the waste of this residual heat. Therefore, it is necessary to design a waste heat recovery device for sizing machines to solve the above problem.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0023] This invention utilizes a waste heat recovery mechanism to efficiently recover waste heat from condensate. High-temperature steam is condensed by a condensing plate within the airflow holes to form condensate containing waste heat. The condensate then enters the heat-conducting pipe through branch pipes and the main pipe. As it flows within the heat-conducting pipe, it transfers waste heat to the cold water in the water tank, raising the temperature of the cold water. The heated water can then be used for slurry preparation or to supplement boiler water, fully utilizing waste heat that might otherwise be wasted, thus improving energy efficiency. It effectively constrains high-temperature steam, preventing its unorganized diffusion. The suction pump introduces steam into the airflow holes through the suction pipe and the circular cavity, achieving directional collection and guidance of steam, improving steam condensation efficiency, thereby increasing recoverable waste heat, reducing energy waste, and lowering energy costs in the production process.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a waste heat recovery device for a sizing machine, comprising:

[0033] The sizing tank 1 is fixedly equipped with a top cover 2, and the top cover 2 is equipped with a waste heat recovery mechanism. It should be noted that it can efficiently recover and treat the waste heat in the condensate, thus avoiding the waste of waste heat.

[0034] The waste heat recovery mechanism includes a frustum 3, an airflow hole 4, a water inlet frame 5, a water inlet hole 6, a branch pipe 7, a water tank 8, a main pipe 9, a heat conduction pipe 10, and an air pump 12;

[0035] An airflow hole 4 is opened on the frustum 3. A condenser plate is fixedly installed on the inner wall of the top of the airflow hole 4. The water inlet frame 5 is fixedly connected to the frustum 3. The water inlet hole 6 is opened on the top of the water inlet frame 5. The branch pipe 7 is fixedly installed on the water inlet frame 5 and the water tank 8. The water tank 8 is fixedly installed on the bottom of the frustum 3. The main pipe 9 is fixedly connected to the branch pipe 7. The heat conduction pipe 10 is fixedly connected to the main pipe 9 and the water tank 8. It should be noted that the heat conduction pipe 10 is connected to an external collection tank for collecting condensate.

[0036] With the above structure, the slurry is heated in the sizing tank 1 to form steam. The vacuum pump 12 is started to guide the steam to the airflow hole 4, so that the steam enters the airflow hole 4 through multiple water inlet holes 6. The steam is condensed by the condenser plate on the inner wall of the top of the airflow hole 4. The condensate with temperature enters the water inlet frame 5 through the water inlet hole 6, and then enters the main pipe 9 through the branch pipe 7. Then it is discharged into the external collection tank through the heat conduction pipe 10. When the condensate with temperature flows in the heat conduction pipe 10, the heat of the condensate can enter the cold water in the water tank 8 to heat the water in the water tank 8. In this way, the waste heat in the condensate can be recovered and the condensate can be collected.

[0037] Specifically, the waste heat recovery mechanism also includes an extraction pipe 13, a connecting frame 14, and a fixing screw 15. The bottom of the extraction pump 12 is fixedly connected to the extraction pipe 13, the extraction pipe 13 is fixedly installed on the frustum 3, the bottom of the connecting frame 14 is fixedly connected to the frustum 3, and the connecting frame 14 is fixedly installed on the top inner wall of the top cover 2 by the fixing screw 15.

[0038] With the above structure, the waste heat recovery mechanism can be disassembled and reassembled as a whole, making it convenient to disassemble and operate when subsequent inspection and maintenance are required.

[0039] Specifically, a guide roller 16 is rotatably connected inside the sizing tank 1. It should be noted that a heating layer is also provided inside the sizing tank 1 for heating the sizing material. This is existing technology and will not be described in detail here.

[0040] Specifically, a heat insulation sleeve is fixedly fitted on the outside of branch pipe 7 to prevent heat loss.

[0041] Specifically, a circular cavity 11 is provided on the truncated cone 3, and the circular cavity 11 is connected to the airflow hole 4. The bottom of the suction pipe 13 extends into the circular cavity 11. An exhaust pipe is fixedly provided on the top of the suction pump 12. A through hole is provided on the top of the top cover 2, and the top of the exhaust pipe passes through the through hole. It should be noted that starting the suction pump 12 facilitates the diversion of the generated hot air towards the airflow hole 4.

[0042] Specifically, branch pipe 7 is connected to the inside of water inlet frame 5, and branch pipe 7 is connected to the inside of main pipe 9. Water tank 8 is fixedly equipped with water inlet pipe and water outlet pipe. It should be noted that water inlet pipe and water outlet pipe are connected to external pipes for water inlet and outlet treatment of water tank 8. In addition, water tank 8 is also equipped with temperature sensor for monitoring water temperature.

[0043] Working principle:

[0044] S1: During the sizing operation, the heating layer in the sizing tank 1 heats the sizing material to maintain it at the temperature required by the process, while generating a large amount of high-temperature steam. The top cover 2 forms a closed space to confine the steam above the tank, preventing unorganized diffusion. After the vacuum pump 12 is started, it generates negative pressure on the circular cavity 11 of the frustum 3 through the vacuum pipe 13, drawing the steam in the top cover into the circular cavity. Through the connection structure between the circular cavity and the airflow hole 4, the steam is evenly distributed into multiple airflow holes 4.

[0045] S2: As the steam rises through the airflow hole 4, it comes into contact with the condenser plate on the inner wall of the top and is cooled and liquefied to form condensate with residual heat. A small amount of uncondensed gas is discharged from the device through the exhaust pipe of the air pump 12. The condensate flows down along the inner wall of the airflow hole, enters the water inlet frame 5 through the water inlet hole 6, and then enters the main pipe 9 through the branch pipe 7. The heat insulation sleeve on the outside of the branch pipe 7 can reduce heat loss during the transportation process and ensure that the residual heat of the condensate is utilized efficiently.

[0046] S3: The main pipe 9 guides the condensate into the heat-conducting pipe 10 that runs through the water tank 8. As the condensate flows in the pipe, it transfers waste heat to the cold water in the water tank through the pipe wall. The water tank 8 is replenished with cold water through the water filling pipe. The heated water can be transported to the sizing system or boiler through the drain pipe to realize the recovery and reuse of waste heat. Finally, the condensate that has completed the heat exchange is discharged into the external collection tank through the end of the heat-conducting pipe for subsequent production cycles. Throughout the process, the connecting frame 14 and the fixing screws 15 ensure that the waste heat recovery mechanism is stably installed on the top cover 2. The guide roller 16 synchronously conveys the yarn to complete the sizing operation. The temperature sensor on the water tank 8 monitors the water temperature in real time to ensure the waste heat recovery efficiency and system operation stability.
