DETAILED DESCRIPTION
[0020] The present invention provides a precise sampling device for cyclic acid final products, such as Figure 1-3As shown, it includes a sleeve 11, a sampling chamber 12, a thread 13, a first baffle plate 14, a distillation hole 15, a condensation cylinder 16, a condensation chamber 17, a first groove 18, a second baffle plate 19, a first condensation tube 20, a second condensation tube 21, a third condensation tube 22, a second groove 23, a first limiting ring 24, a second limiting ring 25, and a spring 26.
[0021] like Figure 1-3 As shown, a sampling chamber 12 is opened in the sleeve 11, and a condensation cylinder 16 is slidably connected to the sampling chamber 12. An elastic component is fixedly connected to one end of the condensation cylinder 16 away from the sleeve 11. A condensation chamber 17 is opened in the condensation cylinder 16, and a condensation tube group is arranged in the condensation chamber 17. A first baffle plate 14 is fixedly connected to the sampling chamber 12, and a second baffle plate 19 is arranged at one end of the first baffle plate 14 away from the condensation cylinder 16.
[0022] A thread 13 is provided at one end of the sampling chamber 12 away from the condensation cylinder 16, and the thread 13 is used to be threadedly connected to the inlet of the reactor. The first baffle plate 14 is slidably connected to the condensation cylinder 16, and a plurality of distillation holes 15 are provided on the first baffle plate 14. A first groove 18 is provided on the condensation chamber 17, and a second baffle plate 19 is slidably connected to the first groove 18. The height and width of the second baffle plate 19 are adapted to the height and width of the first groove 18.
[0023] The elastic component includes a first limiting ring 24, a second limiting ring 25 and a spring 26. A second groove 23 is provided on the condensing tube 16. The first limiting ring 24 and the second limiting ring 25 are both slidably connected to the second groove 23. One end of the spring 26 is fixedly connected to the first limiting ring 24, and the other end of the spring 26 is fixedly connected to the second limiting ring 25.
[0024] The condenser tube group includes a first condenser tube 20 and a second condenser tube 21. One end of the second condenser tube 21 is fixedly connected to the first condenser tube 20. The other end of the second condenser tube 21 is fixedly connected to the third condenser tube 22. The third condenser tube 22 and one end of the first condenser tube 20 are both arranged on the outside of the condenser tube 16.
[0025] When the present scheme is used for accurate sampling of the cyclic acid final product, first, the sleeve 11 is rotated to threadably connect the sleeve 11 to the feed port of the cyclic acid final product reactor through the thread 13, and the first condenser 20 and the third condenser 22 are respectively connected to the condensate circulation device.
[0026] Then, when the cyclic acid final product in the reactor is distilled into the sampling chamber 12, the cyclic acid final product enters the condensation cylinder 16 through the distillation hole 15 and the first groove 18. After condensation, the cyclic acid final product flows along the side wall of the condensation chamber 17 into the bottom of the condensation chamber 17, the weight of the condensation cylinder 16 increases, and the condensation cylinder 16 slides downward.
[0027] Finally, when the condensing cylinder 16 slides downward, the condensing cylinder 16 drives the second limiting ring 25 to move downward, and the second limiting ring 25 generates pressure on the spring 26, thereby compressing the spring 26. As the condensing cylinder 16 slides downward, the first groove 18 on the condensing cylinder 16 coincides with the second baffle plate 19, and the cyclic acid final product cannot enter the condensing chamber 17. Therefore, the purpose of accurately controlling the weight of the cyclic acid final product that can be accommodated in the condensing chamber 17 can be achieved by adjusting the elastic coefficient of the spring 26.
[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
