When the round surface of the semicircular block no longer pushes the scraper, the scraper is reset and moves to the right under the action of the corresponding spring's own elastic force. The reciprocating movement of the scraper enhances the scraping effect of the scraper on the catalyst particles blocked on the surface of the porous metal sheet, thereby re-exposing the effective reaction area.

[0020] Second: The porous metal sheet is knocked by a knocking plate to knock off the catalyst particles blocked on the surface of the porous metal sheet, which reduces the need for additional energy, reduces the energy consumption of the equipment, reduces operating costs, improves the fluid flow in the reaction tank, and allows the reactants to contact the catalyst particles more evenly, thereby optimizing the reaction process.
