[0003] At present, the steam generated by the steam device is used to heat the pot body, and the condensate water generated in the sandwich layer has a high temperature and is directly discharged without recycling, which causes waste of resources. The existing condensate water recovery device collects the condensate water in the sandwich pot and then inputs the condensate water into the steam generator. Although the device is simple, it has many defects: first, the recovery device is easy to evaporate the heat of the condensate water, causing waste of resources; second, too much collected condensate water can cause overflow of the device, insufficient condensate water collection, insufficient steam generator work, pipe blockage or damage to the steam generator, and other problems, which requires multiple technical personnel to watch at any time, wastes manpower, and requires a long time for maintenance, which delays production; third, the condensate water from the sandwich pot has a large pressure and generates vibration, which can easily tear the connection and produce impurities, and can also cause great damage to the equipment. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the above problems, the utility model provides a circulating utilization system of sandwich pot, which can efficiently recycle and utilize the condensate water in the sandwich pot, avoid waste of resources, save manpower and material resources, reduce damage to the device, avoid impurities blocking the pipeline and damaging the steam generator, and solve the problems of overflow of too much condensate water, insufficient condensate water collection and stop of the steam generator, and the system is simple, easy to install, disassemble and maintain, and is conducive to large-scale promotion and application.

[0005] The technical scheme of the utility model is as follows:

[0006] A recycling system for a jacketed kettle comprises a jacketed kettle and a steam generator. The jacketed kettle is provided with a steam inlet and an outlet. The steam inlet is connected to the steam generator via a steam delivery pipe, and the outlet is connected to a condensate recovery pipe, on which a steam trap is provided. The outlet is connected to a water collecting tank via the condensate recovery pipe, and the top of the water collecting tank is connected to an overflow tank via an overflow pipe.

In the prior art, when encountering this situation, the condensed water can usually only be allowed to overflow from the water collecting tank to the outside, causing the environment to be very humid and easily causing safety accidents. Another way is to stop the steam and stop the operation of the double-layer pot, which will delay production. The utility model provides an overflow box, which will allow the excess condensed water to flow to the overflow box through the overflow pipe, which will not delay production and avoid affecting the surrounding environment, thereby reducing the occurrence of safety accidents; the provision of the insulation layer prevents a large amount of temperature loss of the collected condensed water, reduces the waste of resources, and can maintain the recycled condensed water at about 70°C, effectively recycling and utilizing resources; the float liquid level switch provided on the water collecting tank effectively protects It proves that when the amount of condensed water collected is small, water can be added to the water collecting tank in time through the water source, which will not delay the operation of the steam generator, because when the water in the water storage tank of the steam generator is too little, the steam generator will stop working.

Further preferably, the outlet of the water collecting tank is arranged at the bottom of the buffer device.

[0010] Preferably, a drain is arranged at the bottom of the water collecting tank. The arrangement of the drain can enable the water in the water collecting tank to be drained in time when the water collecting tank needs to be repaired, and the impurities in the water collecting tank can also be discharged through the drain.

[0011] Preferably, the water inlet of the water collecting tank is arranged at the middle or lower part of the middle of the water collecting tank. The water inlet is mainly arranged to supplement water to the water collecting tank through the water source when the collected condensate water is insufficient, so as to ensure the normal operation of the steam generator and facilitate the effective operation of the recycling system. When there is sufficient condensate water, the water inlet is closed, and the collected condensate water can be used to supply the steam generator.

[0012] Preferably, the condensate recovery pipe is connected with the condensate inlet of the water collecting tank, and the outlet of the sandwich boiler is higher than the condensate inlet of the water collecting tank, so as to facilitate the flow of the condensate water in the sandwich boiler into the water collecting tank.

[0013] Preferably, a valve is arranged on the pipe through which the water source is connected with the water collecting tank, and the water outlet of the water source is higher than the water inlet of the water collecting tank, so as to facilitate the automatic flow of the water in the water source into the water collecting tank when the valve is opened.

[0014] Further preferably, the water outlet of the overflow tank is connected with the pipe through a return pipe, a valve is arranged on the return pipe, and the water outlet of the overflow tank is higher than the water inlet of the water collecting tank. When the overflow tank collects a large amount of condensate water, the valve on the pipe of the water source is closed, the valve on the return pipe is opened, and the water in the overflow tank flows to the water collecting tank when the float level switch in the water collecting tank is opened.
