[0002] The heating of hydraulic press dies is a commonly used technology in the production of military and civilian protective supplies. Generally, the heat conduction oil heating technology is adopted. Affected by process conditions, the cooling rate of the heat conduction oil is slow, resulting in insufficient production capacity. Therefore, the steam heating mode is adopted. Under general conditions, it is directly discharged, and its heat energy cannot be fully utilized. CN 219744407 U discloses a steam condensate recovery and utilization system, which recovers the condensate after heating the urea dissolution tank to the condensate tank for storage through a condensate pipeline, and sends the condensate after heating the urea solution storage tank to the heating system of the urea workshop through the first pipeline during the heating period and sends it to the condensate tank for storage through the second pipeline during the non-heating period, so as to utilize the temperature and pressure of the condensate generated by the urea solution storage tank to meet the heating requirements of the heating system of the urea workshop. However, the collected hot water is not well utilized. Therefore, it is very important to solve this problem. Summary of the Utility Model

[0003] In view of this, the purpose of the present utility model is to provide a steam heating and condensate water recycling system for a hydraulic press die to solve the problems raised in the above background art.

[0004] Based on the above purpose, the present utility model provides a steam heating and condensate water recycling system for a hydraulic press die, including a hydraulic press die and a steam generator. The head end of the hydraulic press die is connected to the steam generator through a pipeline for generating steam to enter the hydraulic press die. A condensate valve is arranged at the discharge port at the end of the hydraulic press die. The condensate valve is connected to a condensate collection tank through a pipeline. The condensate collection tank includes an upper chamber and a lower chamber separated up and down. The condensate valve is connected to the upper chamber through a rear pipeline.

In the upper chamber, an electric heating wire is also used to heat the water when it is not hot enough to ensure the usage requirements of the radiators; the water used by the radiators flows into the lower chamber of the steam trap collection tank for transfer and buffering storage. The water in the lower chamber finally flows back to the water supply tank through a return water pump. The water supply tank then supplies water to the steam generator through a water supply pump to generate steam. In this way, the waste heat of the hot water generated by the steam is utilized to meet the heating requirements of the workshop. The water can be heated when it is not hot enough to meet the heating requirements of the workshop, and the final water can be reused without waste. An emergency discharge port is provided in the upper chamber for emergency discharge when there is too much hot water, to avoid large-area leakage of hot water and harm to workers; the water supply tank is connected to a pure water machine, so the water is pure water with a high cleanliness.

[0020] As Figures 1 to 3As shown in the figure, a steam heating and condensate recovery system for a hydraulic press die includes a hydraulic press die 1 and a steam generator 2. The first end of the hydraulic press die 1 is connected to the steam generator 2 to generate steam and supply it to the hydraulic press die 1. A steam trap 3 is provided at the discharge port at the end of the hydraulic press die 1. The steam trap 3 is connected to a condensate collection tank 4 through a pipeline. The condensate collection tank 4 includes an upper chamber 5 and a lower chamber 6 separated vertically. The steam trap 3 is connected to the upper chamber 5 through a subsequent pipeline. The upper chamber 5 is connected to a multi-stage radiator 7 through a pipeline. The multi-stage radiator 7 is a group of radiators connected in parallel. The radiators are installed in the workshop. The multi-stage radiator 7 is connected to the lower chamber 6 through a pipeline. The steam generator 2 is connected to a water supply tank 8 through a pipeline. The lower chamber 6 is connected to the water supply tank 8 through a pipeline. A disc-shaped electric heating wire 9 is provided on the inner wall of the upper chamber 5, and a temperature sensor 10 is also provided in the upper chamber 5. Steam is generated by the steam generator 2 to heat the hydraulic press die 1. The hot water generated after the steam is heated by the steam trap 3 is discharged into the upper chamber 5 of the condensate collection tank 4, where it is stored for transfer and buffering. Then, the hot water flows through the multi-stage radiator 7 for heat dissipation. The multi-stage radiator 7 is a group of radiators 18 connected in parallel. The hot water is added to the radiators 18 to ensure the warmth and comfort of the workshop in winter. An electric heating wire 9 and a temperature sensor 10 are also provided in the upper chamber 5. The temperature sensor 10 measures the water temperature in the upper chamber 5. When the water temperature is less than 70 °C, the electric heating wire 9 heats the hot water in the upper chamber 5 to ensure the usage requirements of the radiators. The water used by the radiators flows through the lower chamber 6 of the condensate collection tank 4 for transfer and buffering storage. The water in the lower chamber 6 finally flows into the water supply tank 8, and the water supply tank 8 supplies water to the steam generator 2 to generate steam again.

[0021] An emergency discharge port 11 is provided at the top of the upper chamber 5. The emergency discharge port 11 is connected to the sewer through a pipeline and is used for emergency discharge when there is too much hot water to avoid injury to workers caused by large-area leakage of hot water.

A hot water circulation pump 16 is provided on the pipeline between the upper chamber 5 and the multi-stage radiator 7. These pumps are used to pump the hot water so that the hot water can flow faster and more smoothly.

[0024] The water supply tank 8 is connected to a pure water machine 17 through a pipeline, and the upper chamber 5 is connected to a bathing device through a pipeline. In this way, the water is pure water with a relatively high cleanliness. Since the upper chamber is connected to the bathing device, the water with a relatively high cleanliness can meet the bathing requirements and further utilize the hot water.

[0025] The hydraulic press die 1 is heated by steam generated by the steam generator 2. The hot water generated after the steam is heated by the steam trap 3 is discharged into the upper chamber 5 of the condensate collection tank 4, and is stored in the upper chamber 5 for transfer and buffering. Then, the hot water flows through the hot water circulation pump 16 to the multi-stage radiator 7 for heat dissipation. The multi-stage radiator 7 is a plurality of groups of radiators connected in parallel. The hot water is added to the radiators to ensure the warmth and comfort of the workshop in winter. In addition, in the upper chamber 5, an electric heating wire 9 is also used to heat the water when it is not hot enough to ensure the use requirements of the radiators; the water used by the radiators flows into the lower chamber 6 of the condensate collection tank 4 for transfer and buffering storage. The water in the lower chamber 6 finally flows through the return water pump 15 to the water supply tank 8. The water supply tank 8 then supplies water to the steam generator 2 through the water supply pump 13 to generate steam. In this way, the waste heat of the hot water generated by the steam is utilized to meet the heating requirements of the workshop. The hot water can be heated when it is not hot enough to meet the heating requirements of the workshop, and the final water can be reused without causing waste.
