[0066] The working principle of the embodiment is as follows:

[0067] First, the melt material flows into the inner part of the barrel 2 near the driving motor 11 through the melt feeding pipe 3, and then the powdered adsorbent is introduced into the barrel 2 through the adsorbent feeding pipe 41. It should be noted that the adsorbent feeding pipe 41 is arranged between the melt feeding pipe 3, and the adsorbent feeding pipe 41 feeds the reaction additive through the cooperation of the loss weight scale 42. The use of the loss weight scale feeding can accurately control the proportion of the reaction additive according to the yield of the melt material fed first, so that the adsorbent product with the best adsorption effect can be obtained. The working principle of the loss weight scale 42 and the melt material are both prior art, and will not be described in detail here. The melt material is usually a certain polymer or other base material, which is mixed with the adsorbent after being heated and melted to form a uniform melt.

[0068] The melt material and the powdered adsorbent are fed into the barrel 2 at the same time, and the driving motor 11 is started. The driving motor 11 drives the screw 14 to rotate in the barrel 2 through the coupling 12 and the transmission box 13.

It should be noted that the outer part of the coupling 12 can be provided with a protective cover 150 to avoid injury caused by accidental touch of the operator. The driving motor 11 can use a high-efficiency variable frequency motor matched with an ultra-high torque transmission box 13 to make the melt material and the powdered adsorbent fully mixed and reacted in the barrel 2. The ultra-high torque screw 14 can smoothly convey the mixture to the pelletizing die plate. The barrel 2 and the screw 14 can both use materials that meet the requirements of high corrosion resistance and high wear resistance.
