1、 Overview of SXZ series self-cleaning rotating fine grille

The SXZ series self-cleaning rotary grille is a new type of solid-liquid separation device developed by our company based on the digestion and absorption of advanced technologies at home and abroad.

It is widely used in small and medium-sized wastewater treatment plants, pump station tanks, and other occasions to intercept and remove garbage and floating debris in wastewater.

2、 Working principle of SXZ series self-cleaning rotating fine grille

Wastewater flows into the water tank through the inlet valve and water outlet, delaying the rise of the partition of the flushing water tank to the filtration water level line and evenly distributing it on the surface of the rotating grid cylinder; Purified water enters the interior through the outside of the wedge-shaped grid slot cylinder, and then flows from the interior to the outside through the wedge-shaped grid slot at the bottom of the grid cylinder, self-cleaning the grid under the continuous impact of water flow; At the same time, garbage and floating objects larger than the gap between the grids are blocked by the grid and carried to the other side of the grid by the continuously rotating grid cylinder, and discharged through the unloader; The filtered sewage flows into the water outlet and exits through the drainage outlet. If the solid content in the inlet water is high or the inlet water volume is too large, causing an increase in the water level in the tank, when it reaches the set water level, the liquid level gauge will send a signal, the sound and light alarm will sound, and the continuously variable transmission will be manually adjusted to accelerate the speed of the grid cylinder, thereby increasing the effective filtering area of the grid cylinder and improving its water passing capacity; If the liquid level continues to rise despite increasing the speed of the grid cylinder, and reaches a certain level, the wastewater flows directly into the drainage tank through the overflow tank and exits through the drainage outlet. If the wastewater contains a large amount of oil or grease substances, they will deposit between the wedge-shaped grid gaps, making it difficult for the unloader to remove them, thereby reducing the water passage area of the grid cylinder. At this time, the internal flushing device can be turned on to flush with high-pressure cold (hot) water or gas. The high-pressure water (gas) is sprayed out in a fan shape through the nozzle to clear the grid gaps and remove the attachments inside the grid gaps.
