This invention provides an ultrafiltration membrane module resistant to high suspended solids impact, relating to the field of wastewater filtration technology. It includes a hollow cylinder and an ultrafiltration mechanism within it. The ultrafiltration mechanism includes a membrane filtration unit and an anti-shock component at its lower end. The anti-shock component includes a rotating lower sleeve with lower blades evenly distributed around its outer circumference, and a sludge removal component above it for scraping sludge from the cylinder wall. Below the fixed plate, there is also an mounting sleeve and a rotating upper sleeve, with upper blades evenly distributed around its outer circumference and connected to an upper scraper. During filtration, raw water impacts the lower blades at the inlet and enters the membrane filtration unit, driving the lower scraper to rotate and scrape sludge. Simultaneously, the rising water flow drives the upper scraper to clean the upper section of the cylinder wall. During backwashing, high-pressure purified water impacts the lower blades in the opposite direction, causing them to rotate and scrape sludge, which is then discharged from the sludge removal hole. This invention utilizes hydraulic self-drive to achieve online cleaning of the cylinder wall, effectively buffering the impact of high suspended solids, protecting the membrane surface, and extending its service life.

This invention relates to the field of heat exchange technology and discloses a spiral plate heat exchanger with a segmented cylinder. The heat exchanger includes a heat exchanger body, two sets of spiral plates spirally wound around each other inside the heat exchanger body, and a segmented cylinder coaxially embedded within the cavity enclosed by the two sets of spiral plates. A segmented rubber plate is fixedly installed inside the segmented cylinder.
