Embodiment 1

[0108] Embodiment 1: The deep sludge filter press dewatering of the present invention includes a filter press dewatering device and a filter press dewatering method based on the filter press dewatering device.

[0109] The sludge filter press dewatering device includes: sludge unloader 1, driving frame 2, driving car 3, filter press barrel 4, sludge filter press, filter cloth drum 7, sludge distributing machine 8 and filter barrel automatic cycle shifter Bit machine;

[0110] The sludge distributing machine and the sludge unloading machine are relatively installed and arranged. On the side of the sludge distributing machine and the sludge unloading machine, there are respectively a distributing station and a sludge cleaning station. The distributing station and the sludge cleaning station are located on the same axis;

[0111] There is a sludge filter press between the distributing station and the sludge cleaning station, there is at least one sludge filter press, and there i...

Embodiment 2

[0169] Example 2: Figure 17 and Figure 18 Among them, both ends of the lifting driven shaft 8-1-9 are connected with a driven connecting wheel 8-1-7 through a sleeve 8-1-6; a lifting chain 8-1-7 is bypassed on the sprocket 8. One end of the lifting chain 8-1-8 is connected to the pick-and-place device 8-2, and the other end of the lifting chain 8-1-8 is connected to the lifting hydraulic cylinder 8-1-11.

[0170] Others are the same as in Example 1.

Embodiment 3

[0171] Example 3: Figure 11 Among them, the filter cloth drum lifter 8-1 has two groups with the same structure, which are hydraulic lifting cylinders, the lower end of the hydraulic lifting cylinder is connected to the lifting plate 8-13, and the pick-and-place device 8-2 is connected to the lifting plate 8-13 The lower end moves up and down with the lifting plate 8-13 under the effect of the hydraulic lifting oil cylinder.

[0172] Others are the same as in Example 1.

Abstract

The invention discloses a deep sludge filter-pressing dehydration device and a dehydration method, and belongs to a filter-pressing dehydration device and a dehydration method. According to the device, a sludge distributing machine and a sludge discharging machine are oppositely arranged; a material distributing station and a sludge discharging and cleaning station are arranged on one side of thesludge distributing machine and one side of the sludge discharging machine respectively; a sludge filter press is arranged between the material distribution station and the sludge discharging and cleaning station; a filter pressing station is correspondingly arranged below the sludge filter press; the filter pressing station, the material distributing station and the sludge discharging and cleaning station are positioned on the same axis; filter pressing barrels are arranged on the filter pressing station, the material distributing station and the sludge discharging and cleaning station; a filter barrel automatic circulating shifter is arranged above or on one side of the filter pressing station, the material distributing station and the sludge discharging and cleaning station; and the filter barrel automatic circulating shifter is positioned on the moving tracks of the filter pressing station, the material distributing station and the sludge discharging and cleaning station. Accordingto the invention, no chemical additive is required to be added during dehydration and filter pressing of sludge, so that the cost is effectively reduced, and the operation is stable and reliable; andthe automation degree of equipment is high, and operators are not required to operate on site;

Description

technical field [0001] The invention relates to a sludge filter press dewatering device and a dewatering method, in particular to a deep sludge filter press dewatering device and a dewatering method. Background technique [0002] At present, the working principle of the plate and frame filter press is that the water in the sludge is discharged through the filter cloth through the extrusion of the plate and frame to achieve the purpose of dehydration. It is mainly composed of recessed filter plate, frame, automatic-pneumatic closing system, side plate suspension system, filter plate vibration system, air compression device, filter cloth high-pressure washing device, and is bulky. The plate and frame sludge filter press needs to add iron salt and lime as additives in order to achieve the effect of filter press dehydration, which undoubtedly increases the cost of sludge filter press, and increases the amount of sludge, and then dewaters the sludge . In addition, manual operat...
