[0025] Please see Figure 1 , Figure 4 This utility model provides an embodiment of a protective device for a steam mechanical thermal compressor, comprising a water inlet assembly 1 and a filter water tank 2 fixedly connected to one end of the water inlet assembly 1. A water outlet assembly 3 is fixedly connected to the side of the filter water tank 2 away from the water inlet assembly 1. A steam tank 4 is installed at the end of the water outlet assembly 3 away from the filter water tank 2. A steam flow pipe 5 is welded to one side of the steam tank 4. A steam compressor body 6 is fixedly connected to the end of the steam flow pipe 5 away from the steam tank 4. The water outlet assembly 3 includes a water outlet pipe 31 and a solenoid valve 32 installed on the water outlet pipe 31. A high-pressure water pipe 33 is installed on the side of the solenoid valve 32 near the filter water tank 2. The high-pressure water pipe 33 is fixedly connected to the outlet pipe 31. A solenoid valve 34 is installed on the high-pressure water pipe 33. When the filter water tank 2 is working normally, both the inlet component 1 and the outlet component 3 are in normal flow state. When the filter water tank 2 is not working normally, by closing the solenoid valve 32 and opening the solenoid valve 34, high-pressure water is introduced from the high-pressure water pipe 33 to backwash the filter water tank 2, which avoids impurities and particles from accumulating in the filter water tank 2 for a long time and affecting the filtration effect of the filter water tank 2.

[0026] Please see Figure 2The water inlet assembly 1 includes a water inlet pipe 11 and a solenoid valve 12 installed on the outer surface of the water inlet pipe 11.

[0027] Please see Figure 3 The filter tank 2 includes a filter tank shell 21 and a filter screen 22 installed inside the filter tank shell 21. The side of the filter tank shell 21 near the inlet pipe 11 is fixedly connected to the output end of the inlet pipe 11. The filter screen 22 is located on the side of the filter tank shell 21 near the inlet pipe 11. A partition 23 is welded to the side of the filter tank shell 21 away from the inlet pipe 11. A filter screen 24 is welded to the side of the partition 23 near the outlet assembly 3. The end of the filter screen 24 near the outlet assembly 3 is fixedly connected to the input end of the outlet assembly 3. A water pressure sensor 25 is located on the side of the partition 23 near the filter screen 22. One end of the water pressure sensor 25 passes through the filter tank shell 21 and is fixedly connected to the filter tank shell 21. On the other side of 3, a water pressure sensor 26 is installed.

A water pressure differential sensor 261 is installed on one side of the water pressure sensor 26. A controller 27 is installed on the upper surface of the filter tank shell 21 near the inlet pipe 11. When the water pressure differential sensor 261 detects that the water pressure difference on both sides of the partition 23 is greater than the preset value, it means that the screen holes of the filter screen 24 have been blocked by impurities. At this time, the water pressure differential sensor 261 sends a signal to the controller 27. The controller 27 closes the solenoid valve 12 and the solenoid valve 22, opens the solenoid valve 33, and connects high-pressure water from the high-pressure water pipe 34 to flush the impurities blocked at the screen holes of the filter screen 24 to the screen 12.
