Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 2 shown.

[0016] A variable-gap screw press dehydration integrated machine, which includes a drive motor 1, a variable-pitch shaft 2 and a cleaning system 4, the variable-pitch shaft 2 is covered with a stainless steel elastic filter 5, such as figure 2 As shown, the discharge end of the stainless steel elastic filter screen 5 is equipped with a fixed platen 6, and the feed end is equipped with a movable platen 7. Both the fixed platen 6 and the movable platen 7 are installed on the guide shaft 8, and the movable platen 7 is connected to drive it along the The drive mechanism 9 for the guide shaft 8 to move. During specific implementation, the quantity of driving mechanism 9 is preferably identical with the quantity of guide shaft 8, to realize synchronous pressing and unclamping, also can adopt a driving mechanism multi-point...

Abstract

The invention relates to a variable-gap screw extrusion / dewatering integrated machine which comprises a drive motor (1), a variable-pitch shaft (2) and a cleaning system (4). The machine is characterized in that a stainless steel elastic filter screen (5) is sheathed on the variable-pitch shaft (2); a discharge end of the stainless steel elastic filter screen (5) is provided with a fixed pressure plate (6), and a feed end is provided with a movable pressure plate (7); both the fixed pressure plate (6) and the movable pressure plate (7) are installed on a guide shaft (8); and the movable pressure plate (7) is connected with a driving mechanism (9) for driving the movable pressure plate (7) to move along the guide shaft (8). The variable-gap screw extrusion / dewatering integrated machine can compact the driving mechanism to release compacting force in the shutdown cleaning process, so that the gap of the elastic filter screen naturally widens, and the gap of the filter screen is increased from 0.2-0.4mm to 2-3mm; and thus, the cleaning process is easier, and can save abundant water resources.

Description

technical field [0001] The invention relates to an environmental protection equipment, in particular to a sludge dehydration equipment, in particular to a variable-gap screw press dehydration integrated machine which is easy to clean. Background technique [0002] The screw press sludge dewatering machine is widely used in municipal sewage engineering and water treatment systems in petrochemical, light industry, chemical fiber, paper, pharmaceutical, leather and other industries. [0003] The working principle of the screw press sludge dewatering machine is: before the sludge enters the equipment, PAM is added to the equipment, and after the flocculation reaction, the sludge and water are initially separated. Along the direction of the mud cake outlet, the distance between the screw shafts gradually decreases, the volume of the screw cavity continues to shrink, and the internal pressure gradually increases. Driven by the continuous operation of the screw shafts, the water in...
