[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0021] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0022] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0026] After the telescopic tube is adjusted, materials can be added from the open part. The materials added from the open part will slide from the opening of the telescopic tube into the reaction zone in the three-necked flask;
[0027] The feeding speed is controlled by a graduated rotary valve, which can be purchased from the market. The model is UP-Q61F-10S. When fast feeding is required, the graduated rotary valve is adjusted to a larger value. When slow feeding is required, the graduated rotary valve is adjusted to a smaller value. When feeding needs to be stopped, the graduated rotary valve is closed.
[0028] When quantitative addition is required, first close the scale valve, add the material into the vertical measuring tube, and then quantitatively add the material according to the scale of the measuring tube.
