The outer wall of the diversion pipe 10 penetrates the left and right sides of the heating box 121. The connection ends of the several heating pipes 122 are electrically connected to the inner wall of the base 1 near the diversion pipe. Heating pipes 122 are installed on both sides of the pipe 10 to heat the pipe wall of the diversion pipe 10. The bottom of the heating box 121 is fixedly connected to the top of the base 1.

[0030] The working principle of this dual-condition cooling and heat tracing integrated device for a feed pump will be explained in detail below.
[0031] like Figure 1-5 As shown, when the feed pump operates in dual mode, the pump body in the device is controlled by the electrical box 2. When the temperature is too high, the two flanges 96 are connected by bolts to fix the connection between the connecting pipe 95 and the water supply pipe 94. Check valves 11 and 234 can be opened, while check valves 314 and 415 are kept closed. The dual-mode feed pump 5 transports the material in the material box 3 into the feed pipe 7 through the suction pipe 6. At the same time, the water pump 92 transports the cold water in the cold water tank 91 into the spiral pipe 82 through the suction pipe 93, the water supply pipe 94, and the connecting pipe 95, and then returns to the cold water tank through the return pipe 97. Inside 91, the cold water circulating in the spiral tube 82 cools the wall of the conveying pipe 7. Then, the centrifugal pump 131 is started to transport the cooled material into the storage tank 4 for storage. When the temperature is too low, the heating tube 122 is opened, and the one-way valve 3 14 and one-way valve 4 15 are opened. The one-way valve 11 and one-way valve 2 134 are kept closed. The dual-condition conveying pump 5 transports the material in the material tank 3 into the diversion pipe 10 through the extraction pipe 6. The heat generated by the heating tube 122 heats the wall of the diversion pipe 10. Then, the heated material is transported into the storage tank 4 for storage by the centrifugal pump 131.
[0032] The electrical box, dual-mode feed pump, heating element, water pump, centrifugal pump, and check valve used are all existing products in terms of their specific types and structures. The specific circuit connection structure and control relationship between the electrical box and the dual-mode feed pump, heating element, water pump, and centrifugal pump are also existing technologies, and will not be elaborated on here.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
