MULTI-STAGE VIBROIMPACT DEWATERING OF WET DISPERSED MATERIALS USING HYDRAULIC IMPULSE EQUIPMENT

The paper presents a comprehensive multi-stage technology and original hydraulic impulse equipment (HID) for vibroimpact dewatering of wet dispersed food production waste. Conventional single-stage mechanical dewatering equipment typically achieves insufficient moisture reduction and requires costly thermal post-treatment. The proposed technological line resolves these limitations by dividing the dewatering process into four sequential stages, each employing a dedicated unit of equipment with progressively increasing vibroimpact loading intensity applied to the wet dispersed material. At the first stage, preliminary dewatering is performed on a hydraulic impulse vibroimpact screen, reducing concentrate moisture content to 85%. The screen incorporates a rubber-fabric conveyor belt with riveted U-shaped steel plates, fine filter mesh, and four HID hydraulic cylinders that impart high-frequency vertical oscillations to the belt, forcing liquid through the mesh and holes. At the second stage, the concentrate undergoes further dewatering in a screw press to a moisture content of 75%; the expelled filtrate is collected for subsequent microfiltration. At the third stage, an inertial vibroimpact press-hammer (IVPM) with HID applies simultaneous static, inertial, and vibroimpact loading from above and below, reducing moisture content to 70%. The fourth and final stage employs a roll press with HID, where the concentrate passes in a thin layer between driven and passive rolls subjected to combined static and vibroimpact compression, achieving a final moisture content of approximately 25% without thermal treatment. The filtrate from each stage is directed to microfiltration, ultrafiltration, and nanofiltration installations equipped with HID. The structural designs of all four units of equipment are described in detail. Six principal design requirements for the equipment complex are formulated, covering multi-stage organisation, progressive loading intensification, stepless HID parameter adjustment, use of proven machine bases, vibration isolation, noise control, sensor-based monitoring, and computer-aided remote control of the process.
