Description

Technical Field

[0001] This invention relates to the field of polycrystalline silicon production equipment technology, and more particularly to an apparatus for filling a chlorosilane resin adsorption column with resin. Background Technology

[0002] There are three main methods for loading chlorosilane adsorption resin in the polysilicon production process. The first method involves loading the resin into a chlorosilane resin adsorption column, purging it with nitrogen, and then introducing chlorosilane into the bottom of the column. During this process, because the reaction between chlorosilane and residual moisture in the resin is exothermic, the slow rate of chlorosilane introduction means the heat cannot be carried away in time, leading to localized overheating of the resin, resin pulverization, loss of active groups resulting in resin deactivation, and even safety accidents. The second method involves pouring the resin directly into the chlorosilane resin adsorption column through a manhole. In this process, because chlorosilane has a low vaporization partial pressure, it easily vaporizes and reacts with moisture in the air to generate hydrogen chloride, polluting the environment and harming operators. Furthermore, the resin has a lower density than chlorosilane, and the resin floating on the surface of the chlorosilane cannot react fully, posing a risk of agglomeration and exothermic reactions. Direct pouring also introduces air into the system, jeopardizing production. The third method involves using pneumatic conveying to deliver the resin into the chlorosilane resin adsorption column. During pneumatic conveying, a certain amount of chlorosilane needs to be loaded into the chlorosilane resin adsorption column. In order to ensure that the resin and chlorosilane can fully contact each other, a submersible insertion tube method is required, which requires high nitrogen pressure. Moreover, the pneumatic conveying distance is long and the flow rate is fast, which causes significant wear on the resin. The resin cannot form a uniform dispersion flow in the pipeline, and blockage is very likely to occur during solid phase conveying. Summary of the Invention

[0030] The resin container is fixedly mounted on a support frame for temporary storage of resin to be filled. The lower end of the resin container has a discharge port; the discharge port has a conical structure so that the resin gathers towards the discharge port under its own weight.

[0031] A feed trough is fixedly provided on the upper part of the resin container; the feed trough is located on one side of the resin container; the bottom of the feed trough is inclined towards the resin container to facilitate the operator to fill the resin from the feed trough.
