Description

Technical Field

[0001] This utility model relates to the field of steam heat pump technology, and in particular to a high-temperature steam heat pump hot water and heating equipment. Background Technology

[0002] High-temperature steam heat pumps collect heat from low- to medium-temperature wastewater and exhaust gases discharged or wasted by industrial enterprises, converting it into water at ≤150℃ or high-temperature steam for industrial processes or heating. While existing technologies have achieved a stable supply of hot water, they still have certain drawbacks.

[0003] For example, patent CN207112756U discloses a heat pump steam engine, including a chiller and a water tank. The chiller has a hot air outlet, and the bottom of the water tank has a heating device connected to the hot air outlet. The key feature is that the top of the water tank has a heating frame, and the water tank contains a first partition and a second partition. The surfaces of the first and second partitions have several pairs of flow holes, dividing the water tank into three layers. The uppermost layer has a first outlet and a steam outlet, the middle layer has a second outlet, and the lowermost layer has a third outlet and a water inlet. This invention not only generates steam but also meets the requirements for different water temperatures.

[0004] In the aforementioned existing patents, due to water quality, a large amount of scale will accumulate in the water tank, partition and convection holes after long-term use, affecting the overall heating effect or causing convection blockage. It is necessary to regularly empty the internal hot water and then manually remove the scale inside, which requires a large amount of labor for the staff. At the same time, the device stops operating during the cleaning, which will affect the stable and continuous supply of hot water.

[0005] Therefore, there is an urgent need for a high-temperature steam heat pump hot water and heating equipment to solve the above problems. Utility Model Content

[0027] Reference Figures 1-4 This utility model provides a high-temperature steam heat pump hot water and heating equipment, comprising:

[0028] Water tank 1 is connected to the steam heat pump body 3 via pipe 2. Several partitions 4 are fixedly connected inside the water tank 1, and flow holes 5 are provided on the partitions 4.

[0029] The first cleaning assembly includes a main shaft 6 and several first cleaning components. The main shaft 6 is rotatably connected to the middle of the water tank 1. Several first cleaning components are respectively disposed on the main shaft 6. The water tank 1 is divided into several cavities by several partitions 4. Several first cleaning components are respectively located in several cavities. The first cleaning components are used to clean the scale in the cavities.

[0030] The second cleaning assembly includes a transmission component and several second cleaning components. The several second cleaning components are respectively disposed on several first cleaning components. The transmission component is disposed inside the main shaft 6. The several second cleaning components are respectively connected to the transmission component for transmission. The second cleaning components are used to clean the scale inside the flow hole 5.

[0031] Water tank 1 is connected to steam heat pump body 3 through pipe 2. At the same time, a heating device is installed in water tank 1. Water tank 1 achieves water convection through flow hole 5, thereby achieving hot water supply at different temperatures. This is existing technology and will not be described in detail here.

[0032] The scheme is further optimized. The first cleaning component includes several cleaning plates 7 fixedly connected to the main shaft 6. The several cleaning plates 7 are located in several cavities respectively. The cleaning plates 7 slide in contact with the inner wall of the cavity. The second cleaning component is set on the cleaning plates 7.

[0033] The top of the main shaft 6 extends out of the water tank 1 and is fixedly connected to the output shaft of the motor 17. The cleaning plate 7 is driven to rotate by the motor 17 to scrape and clean the scale on the inner wall of the water tank 1.

[0034] The design was further optimized, and the cleaning plate 7 was redesigned into a U-shaped structure.

[0035] Reference Figure 2 The three sides of the U-shaped cleaning plate 7 make sliding contact with the top of the inside of the water tank 1, the bottom of the partition 4, the inner side wall of the water tank 1, the bottom of the partition 4, and the bottom of the inside of the water tank 1, respectively, to achieve the cleaning of surface scale.

[0036] The solution is further optimized by providing a groove 8 on the top of the cleaning plate 7. The second cleaning component includes a support frame 9 fixedly connected in the groove 8. A rotating shaft 10 is rotatably connected to the support frame 9. A cleaning roller 11 is fixedly connected to the rotating shaft 10. The cleaning roller 11 is in contact with the partition plate 4. The rotating shaft 10 is connected to the transmission component.

[0037] Reference Figure 3 The cleaning plate 7 cleans the scale at the bottom of the partition 4, and the cleaning roller 11 inside cleans the scale inside the flow hole 5 on the partition 4.

[0039] Reference Figure 4 The support rod 12 is fixedly connected to the bottom of the water tank 1. When the main shaft 6 rotates, it drives the cleaning roller 11 to make a circular motion around the central axis. The rotating shaft 10 on the cleaning roller 11 rotates under the action of the meshing first bevel gear 13 and second bevel gear 14. When rotating, it drives the cleaning roller 11 to rotate synchronously, thereby driving the cleaning roller 11 to move at the bottom of the partition 4, so as to clean the scale on the partition 4 and the flow hole 5.
