The plate-type sludge dewatering machine adopts elastomers positioned among pressing filter plates, adjacent anti-thrust filter plates, air-inlet filter plates, feeding filter plates and thrust filter plates to form at least three hermetic pressing filter chambers variable in volume, utilizes the compression deformation and resilience of the elastomers to deep squeeze and dewater a filter cake, and adopts sealing plugs which are arranged in front of air-inlet holes of the air-inlet filter plates and the thrust filter plates and are on positions opposite to feeding holes on the feeding filter plates and the anti-thrust filter plates, wherein the feeding filter plates are adjacent and involutory to the air-inlet filter plates. After low-pressure filter dewatering is over and feeding is stopped, the sealing plugs block and seal the feeding holes so as to prevent sludge from flowing back and entering pipelines during pressing filtration. The dewatering method adopts the variable hermetic pressing filter chambers formed by the elastomers to perform pressing filtration and dewatering, and adds the operation of adopting the sealing plugs to block the feeding holes before high-pressure squeezing-dewatering operation. The invention has the advantages of high dewatering efficiency, strong adaptability, low energy consumption, low use cost and the like.

PendingCN112858025AAccurate measurement of axial compression performanceWide applicabilityMaterial strength using tensile/compressive forcesAxial compressionConstruction engineering
The invention relates to a test device for measuring the axial compression performance of a composite material pipe for structural engineering. The test device is characterized by comprising an upper end plate, a lower end plate, a semicircular steel bar, an axial strain gauge and an annular strain gauge, the upper end plate and the lower end plate are the same in structure, each of the upper end plate and the lower end plate comprises a circular end plate and a cylindrical bulge positioned in the center of the end plate, the two semicircular steel bars are fixed on the end plates through glue, an annular groove is formed between the two semicircular steel bars and the cylindrical bulge, and the groove is used for accommodating the end part of a tubular compression sample; the groove is filled with high-strength gypsum to fix the end part of the sample with the end plate; the axial strain gauge and the annular strain gauge are uniformly distributed on the outer surface of the sample around the circumference of the sample and are positioned in the middle of the sample. The invention further relates to a test method for measuring the axial compression performance of the composite material pipe for structural engineering. The device is simple in structure, flexible and convenient in test method operation, wide in applicability and high in detection precision, and belongs to the technical field of structural material performance detection in civil engineering.
