The bottom ends of the two tooth frames 19 are fixedly connected to connecting plates 20, and the bottom ends of the two connecting plates 20 are fixedly connected to L-shaped cleaning brushes 21. The two L-shaped cleaning brushes 21 are both fitted with the smoke filter plate 5.

The two positioning blocks 22 are respectively fixedly connected to the two tooth frames 19, and the two positioning blocks 22 slide in the two positioning grooves to ensure the horizontal movement of the two tooth frames 19.

[0033] Reference Figure 2 and Figure 3 The boiler body 1 is connected to the top of the pretreatment box 2 via a smoke inlet pipe, and one side of the pretreatment box 2 is connected to the condenser 7 via a smoke delivery pipe.

[0034] The implementation principle of the electric heat pump steam boiler and ice maker integrated machine of the embodiment of the present application is as follows: the flue gas of the boiler body 1 enters the pretreatment box 2 through the smoke inlet pipe, is filtered by the smoke filter plate 5, and is transported to the condenser 7 through the smoke delivery pipe. Since the high-temperature and high-pressure gas passes through the condenser 7, the heat energy is released here and transferred to the water or other fluid used as the heat source. In this process, the working medium is condensed into a liquid state and releases a large amount of heat energy. It is filtered again through the filter 8 and passes through the expansion valve 9 after filtration. The condensed working medium is decompressed through the expansion valve 9 to reduce its temperature and pressure and then enters the evaporator 10. Since the evaporator 10 is generally a closed container containing supplied water, the heat energy provided by the electric heat pump circulation system heats the water and converts it into steam. The evaporator 10 usually contains a heating element (such as an electric heater) inside to provide additional heat to help heat the water to the boiling point and generate steam. Once the water is heated to the boiling point, the generated steam will be led out of the evaporator 10 and used for heating, cooking, drying and other purposes in the industrial production process. The low-temperature and low-pressure liquid refrigerant, The low-temperature and low-pressure vapor refrigerant entering the evaporator 10 evaporates rapidly and absorbs heat, causing the water flowing into the inner wall of the evaporator 10 to cool down and freeze rapidly. The rolling ice blades then cut the ice flakes into pieces and drop them into the ice storage cabinet. The evaporator 10 is an important part of the ice maker and is a part of the ice maker that makes ice. The steam separates the gas and liquid through the gas-liquid separator 11, is compressed into high-temperature and high-pressure gas through the compressor 12, and then condensed into low-temperature and low-pressure gas-liquid through the condenser 7. When it is necessary to clean the smoke filter plate 5, start the motor 3 so that the rotating rod 13 drives The rotating flushing plate 14 rotates and flushes the smoke filter plate 5 through a plurality of spray nozzles. At the same time, the rotating rod 13 drives the worm wheel 17 to rotate through the worm 15, and the worm wheel 17 drives the transmission rod 16 to rotate. The transmission rod 16 drives two fixedly connected sector gears 18 to rotate and drives two tooth frames 19 to reciprocate. The two tooth frames 19 drive two L-shaped cleaning brushes 21 to reciprocate through two connecting plates 20 to clean the stains in the gap between the pretreatment box 2 and the smoke filter plate 5, thereby achieving the effect of inconvenient cleaning of the gap.
