Abstract

The invention relates to a dynamic gap type screw press comprising a spiral auger driven by a speed reducer and front and rear flange sleeves for supporting the spiral auger, wherein moving and static sheet groups matched with the spiral auger are arranged between the front flange sleeve and the rear flange sleeve; the front flange sleeve is provided with a feed opening; the rear flange sleeve is provided with a discharge opening; the spiral auger consists of a tapered shaft and blades; the outside diameters of the blades are equal; the screw pitches of the blades are equal; the inside diameters of the moving and the static sheet groups are greater than the outside diameter of the blades of the spiral auger; and the inside diameters of moving blades of the moving and the static sheet groups are smaller than the outside diameter of the blades of the spiral auger. According to the invention, sludge is propelled and extruded in the moving and the static sheet groups by the spiral auger consisting of the tapered shaft and the equidistant blades so as to realize the solid-liquid separation. The dynamic gap type screw press has simple structure and is convenient to process and stable for dehydration and has long service life; the equidistant blades have high rigidity; and the moving and the static sheet groups have the functions of draining, automatically cleaning, preventing blockage and the like.

Description

technical field [0001] The invention relates to a press machine, in particular to a dynamic gap screw press machine which is driven by a screw and slides in the gap between static plates. Background technique [0002] Traditional solid-liquid separation devices include vacuum filters, pressurized filters, centrifugal dehydrators, belt filter presses, plate and frame filter presses, etc. Due to the use of filter screens in the above devices, the sludge is easy to collect in the meshes of the filter screens. The filter screen is blocked due to retention in the medium, which reduces the efficiency of solid-liquid separation, and the filter screen has a short service life, which also brings a lot of inconvenience to the maintenance work of the device. At present, a screw-type extrusion device is generally used, and the screw shaft drives the blade to spirally push the extruded sludge to realize solid-liquid separation, which overcomes the clogging of the filter screen and elimin...
