The WLSY Type Shaftless Screw Conveyor and Compactor (also known as a shaftless screw press) is a novel solid-liquid separation device engineered specifically for the sewage treatment process. It brilliantly integrates the transportation and compaction of grid slag into a single continuous operation. Once the moisture-laden slag salvaged by the screen cleaner is conveyed and compacted by this equipment, its volume and water content are substantially reduced, greatly facilitating subsequent external transport and disposal.
The machine primarily consists of a drive unit, shaftless screw, U-shaped trough, bracket, lining plate, cover plate, inlet, compacting section, outlet, and drain pipe. During operation, materials enter via the inlet, are forcefully pushed forward by the screw to the compacting section for deep dewatering, and are finally discharged from the outlet. Simultaneously, the extracted wastewater flows safely through the drain pipe directly back into the grid channel.

Core Features
All-in-One Conveying and Pressing: Designed as a highly integrated unit, the machine boasts a versatile, multi-functional nature. It seamlessly transports intercepted grid slag while simultaneously pressing and dewatering it in the compacting section, offering a highly efficient, one-step solution for slag volume reduction.
Bearingless Compacting Section for Smooth Flow: The equipment features a brilliantly simplified structure, notably eliminating all internal bearings within the high-stress compacting section. This mechanical optimization ensures that materials flow smoothly without tangling or clogging, while also rendering routine maintenance exceptionally simple and fast.
Fully Enclosed Structure Prevents Pollution: Understanding that grid slag can emit foul odors and leak contaminated fluids, the equipment is designed so that, except for the necessary open inlet and outlet, the entire trough can be fully covered and sealed. This strict sealing prevents any dirty material from overflowing, significantly reducing air pollution in the surrounding plant environment.
Frequently Asked Questions
Where does the wastewater extracted during pressing go? Will it mess up the workshop floor?
It will not dirty the floor. The equipment is outfitted with a dedicated drain pipe. The water forcefully squeezed out in the compacting section flows centrally through this drain pipe and is safely and properly directed straight back into the grid channel, ensuring the site environment remains neat and sanitary.
What is the primary function of this machine?
The WLSY Shaftless Screw Conveyor and Compactor is an innovative piece of equipment designed to achieve the integration of conveying and pressing grid slag. Its primary purpose is to transport and deeply compress the water-logged slag salvaged by the screen cleaner, vastly reducing its physical volume to facilitate easy loading and external transportation.
Does the machine emit a severe foul odor while running?
The equipment offers excellent environmental protection. Aside from the necessary openings for material entry and exit, the remainder of the U-shaped conveying and pressing trough can be fully covered and sealed during operation. This strict enclosure guarantees that no materials spill out, drastically reducing odor emission and air pollution.
