The processing method of the fixed ring of the ring piece of the screw stacking machine

- Oct 29, 2020-

At present, in the domestic market, the screw stacking sludge dewatering machine is widely used. The screw stacking machine is a kind of equipment that uses screw extrusion to remove sludge. The technology originates from Japan and is used in aquaculture wastewater treatment, food and beverage, Various industries such as papermaking and processing. No clogging, high processing efficiency and simple operation. The core body is composed of moving ring, fixed ring and screw shaft. The following describes the processing methods of the moving and fixed rings of the screw stacker.

The current mainstream processing method is laser cutting of 304 stainless steel sheet. The thickness of the plate is generally about 2.5mm. As the market price of screw stacking machines once dropped, some screw stacking machine manufacturers use PA or PE injection molding to reduce equipment costs, and their thickness is generally more than 5mm. The first processing method is the current mainstream processing method, and it is also a processing method adopted by most snail sludge dewatering machine manufacturers. It has the advantages of convenient processing, convenient material acquisition, high ring sheet hardness, strong structure, good flatness, and finished products. The advantages and disadvantages of high rate are high cost and not resistant to chloride ion corrosion. The plastic ring has the advantages of low processing cost, certain wear resistance, high acid and alkali resistance, but the disadvantages are poor hardness, poor impact resistance, low processing accuracy, and poor structure.
