DETAILED DESCRIPTION

[0021] Example 1, see the attached specification Figure 1-2A chlorophenol finished product automatic packaging device comprises a receiving tank 13 connected to a discharge port of a distillation tower 11 through a feed pipe 12, and a packaging machine 14. A discharge port is provided at the bottom of the receiving tank 13, and the discharge port is connected to an inlet of the packaging machine 14 through a feed pipe 20. A cooling water pipe 15 is provided on the outer wall of the receiving tank 13, and a cooling water regulating valve 151 is provided on the cooling water pipe 15. The cooling temperature is adjusted by the cooling water regulating valve 151 to control the temperature of the receiving tank 13 to be 5-10°C higher than the crystallization point of chlorophenol (chlorophenol is stable and high after being extracted from the distillation tower 11), and a nitrogen pipeline 16 is connected to the upper part of the receiving tank 13, and nitrogen is introduced into the receiving tank 13 through the nitrogen pipeline 16.

[0022] The middle part of the cooling water pipe 15 is a spiral tube, and both ends of the spiral tube extend to the two ends of the receiving tank 13. The spiral tube is wound around the outer wall of the receiving tank 13. The spiral tube can more fully exchange heat with the receiving tank 13, and the cooling and temperature control efficiency is higher and the effect is better.

[0023] A tank insulation layer 171 is wrapped around the outer side of the receiving tank 13, and a tank protection layer 172 is provided outside the insulation layer. The insulation layer and the protection layer reduce the heat exchange between the cooling water pipe 15 and the outside world to ensure the cooling effect.

[0024] The packaging machine 14 is provided with an exhaust pipe 142, on which an exhaust fan is installed. The outer end of the exhaust pipe 142 is connected to the exhaust system in the workshop, and the chlorophenol generated by the packaging is discharged from the workshop in time through the exhaust fan.

[0025] The packaging machine 14 is an automatic filling packaging machine 14 with a weighing function. A temperature measuring point is provided in the middle of the receiving tank 13, and a thermometer 19 is installed at the temperature measuring point to monitor the stability of the material in the receiving tank 13 in real time.

[0026] The working process and principle of this embodiment are as follows: the chlorophenol extracted from the distillation tower 11 is sent to the receiving tank 13 through the feed pipe 12, and the temperature of the receiving tank 13 is controlled by the cooling water pipe 15 to keep the material in the receiving tank 13 in a liquid state, and nitrogen is filled into the receiving tank 13 through the nitrogen pipeline 16 for protection, and the nitrogen pressure is controlled at about 0.05MPa to prevent the chlorophenol from being oxidized in the receiving tank 13, and then the liquid chlorophenol enters the packaging machine 14 from the feed pipe 20 for high-efficiency automatic filling and bearing. During the filling process, the storage time of the chlorophenol in the receiving tank 13 should be controlled to be less than 72 hours to avoid discoloration of the material stored for a long time.

[0027] Example 2, see the attached specification Figure 1 , 3In this embodiment, based on the first embodiment, a heating pipe 18 of the same length as the feeding pipe 20 is provided on the outer side of the feeding pipe 20. The heating pipe 18 is a spiral pipe. After the material enters the feeding pipe 20 from the receiving tank 13, the stability will decrease. The feeding pipe 20 is heated by the heating pipe 18 to control the material temperature to be 5-10°C higher than the crystallization point. The outer side of the heating pipe 18 is wrapped with a pipe body insulation layer 181 and a pipe body protective layer 182 to avoid heat loss and improve the heating effect. An electric heating device 141 is installed on the material pipe inside the packaging machine 14. When the indoor temperature is low, the temperature of the material entering the packaging machine 14 will drop rapidly, and crystallization blockage is likely to occur in the pipeline of the packaging machine 14. The electric heating device 141 can effectively solve this problem.
