However, since a heating structure is provided on the outer surface of the metering pump, and the motor itself generates heat when the metering pump is running, and the heating operation is performed again, the motor heats up too much and is easily damaged, resulting in poor practicality. In view of this, a polyester ultra-fine denier fiber production device is provided to overcome the above-mentioned defects. Utility Model Content

[0022] Reference Figure 1-Figure 4The utility model provides a polyester ultra-fine fiber production device: comprising a metering pump 1, the outer wall of the metering pump 1 is sleeved with a heat-conducting shell 2, the left side of the heat-conducting shell 2 is connected with a first connecting pipe 3, the left side of the first connecting pipe 3 is connected with a water storage tank 4, the inside of the water storage tank 4 is fixed with a submersible pump 5 interconnected with the first connecting pipe 3 by screws, the upper end of the heat-conducting shell 2 is connected with a second connecting pipe 6, the end of the second connecting pipe 6 is connected with a buffer box 7, the upper surface of the buffer box 7 is installed with a protective cover 8, the upper end of the protective cover 8 is connected with a delivery pipe 9, the end of the delivery pipe 9 is connected with a sleeve arranged on The heating element 10 on the metering pump 1 and the heating tube 11 are installed inside the buffer tank 7. The heat exchange fluid in the water tank 4 is pumped out by the submersible pump 5 and sent to the inside of the heat-conducting shell 2. The heat generated when the motor is running is absorbed by the heat-conducting shell 2, and the heat is transferred to the heat exchange fluid. The heat-conducting fluid is continuously transported to the heat-conducting shell 2 and enters the buffer tank 7. Since the heat-conducting fluid is preheated when passing through the heat-conducting shell 2, the set heating tube 11 can heat the heat-conducting fluid faster and can indirectly cool the motor, thereby ensuring the working temperature of the motor and improving its practical life.

[0023] As a further implementation scheme of the above technical scheme: the input end of the metering pump 1 is connected to a feed pipe 12, the output end of the metering pump 1 is connected to a discharge pipe 13, the feed pipe 12 on the metering pump 1 is connected to the raw material pipe, and the discharge pipe 13 is connected to an external processing equipment, so as to transport the raw materials.

Heat is generated when the motor is running, and the heat is absorbed by the heat-conducting shell 2, and the motor is indirectly dissipated to transfer the heat to the heat exchange In the liquid, the heat-conducting liquid is continuously transported to the heat-conducting shell 2, and with the cooperation of the second connecting pipe 6, the heat-conducting liquid enters the buffer box 7. Since the heat-conducting liquid is preheated when passing through the heat-conducting shell 2, the set heating tube 11 is started, which can heat the heat-conducting liquid faster, and then enters the heating element 10 through the delivery pipe 9 on the protective cover 8. The set heating element 10 is sleeved on the outer surface of the pump body, so that the heat-conducting liquid indirectly heats the pump body, and the spinning flowing in the pump body is heated, thereby increasing the melt fluidity, improving the spinnability of the melt, increasing the temperature of the nascent fiber, and improving the post-processing performance of the fiber. The set insulation shell 14 can keep the heating element 10 warm.

[0027] As a further implementation scheme of the above technical scheme: the inner wall of the upper surface of the water storage tank 4 is threadedly connected with a connecting block 18 fixedly connected to the buffer box 7, and the water storage tank 4 can be removed from the buffer box 7 through the connecting block 18 on the buffer box 7.

[0028] As a further implementation scheme of the above technical scheme: four fixing screws 19 are symmetrically installed on the upper surface of the protective cover 8, the heating tube 11 is fixedly connected to the buffer box 7, and the fixing screws 19 are unscrewed to separate the fixing screws 19 and the threaded groove 20, so as to facilitate the disassembly of the protective cover 8.

[0029] As a further implementation scheme of the above technical scheme: the ends of the four fixing screws 19 are threadedly connected to the threaded grooves 20 opened on the buffer box 7, the inner wall of the heating element 10 is tightly fitted with the outer wall of the metering pump 1, and the heat transfer liquid that continuously enters the heating element 10 can flow into the water storage tank 4 again with the cooperation of the return pipe 15, so as to be recycled.

[0030] During specific implementation, the heat transfer liquid that continuously enters the heating element 10 can flow into the water tank 4 again with the cooperation of the reflux pipe 15 for recycling, and a cooling device can be added to the first connecting pipe 3 to cool the heat exchange liquid when passing through the first connecting pipe 3, and then enter the heat-conducting outer shell 2 for heat exchange to avoid the heat exchange liquid temperature being too high and affecting the indirect heat dissipation effect of the motor. The sealing cover 17 is removed, and the heat exchange liquid can be added to the water tank 4 through the liquid filling port 16. The water tank 4 can be removed from the buffer tank 7 through the connecting block 18 on the buffer tank 7, and the fixing screw 19 can be unscrewed to separate the fixing screw 19 and the threaded groove 20, so as to facilitate the disassembly of the protective cover 8.
