[0021] like Figures 1 to 4 As shown, the utility model relates to a steam condensate heat energy recovery and preheating bath water device, comprising a water collecting shell 1 for centralized steam condensation water, the inlet end of the water collecting shell 1 is connected to the steam condensate generated by the steam cylinder, the bath water heat exchanger, and the turbulent heat exchanger for winter heating through a multi-way joint, the outlet end of the water collecting shell 1 is connected to a pump body 2, the pump body 2 is connected to a filter shell 3, a coil heat exchanger 7 is provided on one side of the filter shell 3, and the coil heat exchanger 7 is connected on one side to a water tank 8 for the condensed water after centralized heat exchange, a cold water inlet end 701 and a cold water outlet end 702 are provided in the central area of ​​the coil heat exchanger 7, the cold water inlet end 701 is connected to an external cold water source, and the external cold water source can be tap water connected through a pipeline, the cold water outlet end 702 is connected to a hot water tank 9 through a pipeline, the coil heat exchanger 7 and the filter shell 3, the pump body 2 and the filter shell 3, the water collecting shell 1 and the pump body 2 are all connected through pipelines (such as Figure 1 );

[0022] The filter shell 3 is connected to the hot water inlet of the coil heat exchanger 7, and the hot water outlet of the coil heat exchanger 7 is connected to the grey water tank 8, which is the heat source channel. The coil heat exchanger 7 is passed through a plurality of hollow copper tubes. The middle space is used for cold water to pass through the outer periphery of the copper tube to achieve heat exchange. This is an existing device, and the specific internal structure and working principle are no longer described in detail. The heat exchange can be achieved by passing the external cold source through the outer walls of the plurality of copper tubes that absorb heat, and then stored in the hot water tank 9 for reuse. The condensed grey water stored in the grey water tank 8 after heat exchange can be used for water replenishment of the hospital's second phase central air-conditioning system, floor cleaning, and toilet flushing.

[0023] Since the steam cylinder, bath water heat exchanger, and turbulent heat exchanger for winter heating are mechanical equipment, there will be impurities in the water in the high-temperature steam condensation under the operating environment. In order to filter the impurities, a filter screen plate 4 is installed inside the filter shell 3, and in order to reduce the occurrence of blockage, the filter screen plate 4 is a conical surface structure protruding toward the center. A plurality of holes for filtering are opened on the filter screen plate 4. A spiral transmission structure 5 is provided in the center of the filter shell 3. The spiral transmission structure 5 includes a propeller blade 501. The front of the propeller blade 501 faces the liquid inlet position of the filter shell 3. The spiral transmission structure 5 also includes a screw thread connected to the propeller blade 501. The center rod 502 is connected to the center, and the outer periphery of the center rod 502 is rotatably connected to multiple connecting plates 503. The connecting plates 503 are fixed to the inner wall of the filter shell 3. The outer periphery of the center rod 502 is connected to a rotary plate 504 for scraping impurities. The rotary plate 504 fits with the top of the filter mesh plate 4. A through opening is opened on the outside of the filter shell 3, and a debris collection shell 10 is installed at the through opening. The debris collection shell 10 is provided with a valve port 11. Opening the valve port 11 can help clean up the impurities. Combined with the impact of the water flow, it will drive the rotary plate 504 to rotate, which can scrape the impurities. Combined with the impact of the water flow, the impurities will be flushed to the edge and discharged into the debris collection shell 10.

[0024] In order to further play a certain role in heat preservation for the water in the condensation of high-temperature steam, a friction overheating mechanism 6 is provided below the spiral transmission structure 5. The friction overheating mechanism 6 includes a movable plate 601 and a fixed plate 602 made of metal material. The center of the movable plate 601 is fixed to the periphery of the center rod 502, and the outer wall of the fixed plate 602 is fixed to the inner wall of the filter shell 3. The adjacent sides of the movable plate 601 and the fixed plate 602 are fitted together. The fitting sides of the movable plate 601 and the fixed plate 602 are integrally formed with staggered convex patterns 603. The movable plate 60 1 and the fixed plate 602 are respectively provided with a first water inlet and a second water inlet, the diameter of the second water inlet being larger than the first water inlet. By having the second water inlet having a larger diameter than the first water inlet, it is ensured that the heat generated by rotation friction is not affected at the same time, the staggered convex patterns 603 can make them fit together, and the staggered convex patterns 603 can greatly increase the fitting area, thereby increasing the effect of frictional heat generation, so that when the high-temperature steam condenses and the water passes through the movable plate 601 and the fixed plate 602, the heat generated by friction has a certain thermal insulation effect.

[0025] It should be noted that the filter shell 3 is a structure composed of a shell, a bottom plate and a top plate to facilitate internal maintenance. The number of groups of movable plates 601 and fixed plates 602 can be selected according to the situation to achieve better insulation effect, and the above-mentioned pipeline can add a water pump according to the situation to ensure infusion efficiency.

[0026] Working principle: This embodiment provides a steam condensate heat energy recovery and preheating bath water device. When in use, the pump body 2 is controlled by the external control structure to suck the high-temperature steam condensate collected in the water collecting shell 1 and transport the high-temperature steam condensate. In the process of the high-temperature steam condensate passing through the filter shell 3, it will be filtered by the filter screen 4. The impact of the water flow drives the rotation of the propeller blades 501, and then the center rod 502 rotates to rotate the rotary plate 504, which can scrape the impurities and discharge them into the interior of the impurity collecting shell 10. At the same time, the friction between the movable plate 601 and the fixed plate 602 generates heat, and the water outlet is combined with the water outlet, so that when the high-temperature steam condensate passes through the movable plate 601 and the fixed plate 602, the heat generated by friction has a certain thermal insulation effect. In the process of the high-temperature steam condensate passing through the coil heat exchanger 7, cold water is input at the same time to realize heat exchange and utilize the heat resources. Then, through the storage in the medium water tank 8 and the hot water tank 9, the water resources can be reused.

[0027] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
