Dewatering unit 1 is used for the mud of sludge pump 3 outputs is carried out press filtration, and the moisture in the described mud of filtering obtains mud cake, and described mud cake is transported in described mud storing unit 2.
Wherein dewatering unit 1 can have the equipment of mud press filtration function for pressure filter or other, does not enumerate herein.
The sludge treatment system of the present embodiment, the mud that sludge pump 3 extracts is not directly to be stacked on mud storing unit 2, but at first be transported to dewatering unit 1 place, the mud that 1 pair of sludge pump of dewatering unit 3 extracts carries out press filtration to be processed, moisture in the described mud of filtering, obtain mud cake, and described mud cake is transported in mud storing unit 2.Because described mud cake is to be obtained by mud filtering moisture to a certain degree, compare with the mud that directly extracts from the river course in prior art, water content in mud cake is few, makes sludge pump 3 can extract the loading tolerance limit that just can reach mud storing unit 2 after the mud in larger zone at every turn.In the situation that the desilting zone is definite, load-carrying mud storing unit 2 is determined, adopt sludge treatment system and method for the present invention, can reduce the number of times of mud storing unit 2 round transports, and then improve the efficient of desilting.
The present embodiment 2 provides a kind of sludge treatment system on the basis of embodiment 1, to shown in Figure 4, comprise mud storing unit 2, sludge pump 3 and a plurality of dewatering unit 1 as Fig. 2.
A plurality of dewatering units 1 are connected with sludge pump 3 gatings by multi-direction switch 4.
As shown in Figure 2, so that being set on mud storing unit 2, two dewatering units 1 describe as example.
When dewatering unit 1 was two, multi-direction switch 4 was two-way switch, and the gating of controlling two dewatering units 1 connects.
Particularly, multi-direction switch 4 can be the pneumavalve lock.
As shown in Figures 2 and 3, the dewatering unit 1 of gating is used for the mud of sludge pump 3 outputs is carried out press filtration, and the moisture in the described mud of filtering obtains mud cake.
Wherein, be provided with filtrate output terminal and mud cake output terminal on each dewatering unit 1; The mud of exporting when 1 pair of sludge pump of dewatering unit 3 carries out the press filtration processing, and the moisture in the mud of filtering is discharged by the filtrate output terminal.For example, the filtrate output terminal directly is communicated with the river course, the moisture in the mud of filtering directly enters in the river course, and this kind mode can make dumping of filtrate easier.
Described mud cake output terminal is used for the output mud cake.
The dewatering unit 1 of gating, be not used for being stored in the mud cake output of its press filtration cavity volume.
As shown in Figure 4, dewatering unit 1 comprises compressing member and a plurality of filter plate of arranging side by side 8; Wherein compressing member does not draw.
Compressing member is used for a plurality of filter plates 8 are compressed; Form the press filtration cavity volume between two adjacent filter plates 8.
In the present embodiment, filter plate 8 is sunk structure for both sides, and when compressing member compressed a plurality of filter plates 8,8 adjacent of two filter plates just formed the press filtration cavity volume.

The mud cake that wherein produces in pressure-filtering process was stored in the press filtration cavity volume of dewatering unit 1 before reaching the processing tolerance limit of dewatering unit 1.
When the dewatering unit 1 of gating reaches the sludge treatment tolerance limit, switch to not the dewatering unit 1 of gating by multi-direction switch 4 and proceed sludge treatment, a plurality of dewatering unit 1 like this alternately carries out processed to the mud that sludge pump 3 extracts, and can further improve the processing efficiency of mud.
The sludge treatment tolerance limit of the dewatering unit 1 of gating is that the permeability according to the filter cloth on filter plate 8 judges, but because filter cloth is arranged on filter plate 8, and filter plate 8 is arranged on the inside of dewatering unit 1, the permeability of direct-detection filter cloth relatively is not easy to realize.
Therefore, in the present embodiment, the permeability of the work output indirect detection filter cloth by indirect detection filtrate output terminal filtrate.
Therefore, be provided with a flow of filtrate monitor on each dewatering unit 1, correspondence is sent the filtrate flow value of the filtrate output terminal of each dewatering unit 1;
Described sludge treatment system further comprises controller 5;
The filtrate flow value that sends according to the dewatering unit 1 of gating like this judges whether dewatering unit 1 reaches the sludge treatment tolerance limit.
The filtrate flow value that sends when the dewatering unit 1 of gating is during less than default minimum filtrate flow value, and expression has reached the sludge treatment tolerance limit of the dewatering unit 1 of gating, and switch to the not dewatering unit 1 of gating with multi-direction switch 4 this moment.
After multi-direction switch 4 being switched to the dewatering unit 1 of gating not, the dewatering unit 1 of current gating continues that the mud that sludge pump 3 extracts is carried out press filtration to be processed, and the mud in the dewatering unit 1 that reaches the sludge treatment tolerance limit is exported dump.
When dewatering unit 1 was exported dump, the filter plate 8 that presses together was opened, and a part of mud cake comes off under the effect of self gravitation, and remaining mud cake is by the manual method dump.
In prior art, generally will be stored in the mud cake removal of dewatering unit 1 by manual method.But, export dump by manual method cumbersome, and the time of dump is long.
In the present embodiment, as shown in Figure 4, the both sides of the filter plate 8 of dewatering unit 1 are provided with wicker, and filter plate 8 is overlapped on the crossbeam that is arranged on filter plate 8 both sides by wicker.This kind design can make filter plate 8 move along the length direction of crossbeam.If filter plate 8 is subject to along the perpendicular reactive force of the length direction of crossbeam, filter plate 8 also can be along moving with the perpendicular direction of the length direction of crossbeam.
Therefore, in the present embodiment, be provided with mud cake vibrating arm 9 and tremble mud electric motor 11 below filter plate 8;
Tremble mud electric motor 11, be used for driving mud cake vibrating arm 9 and rotate;
Mud cake vibrating arm 9 is used for making filter plate 8 to produce the vibration perpendicular with the length direction of mud cake vibrating arm 9.
Wherein the sludge treatment system, further comprise: timing register;
Described timing register is used for the time of trembling 11 described mud cake vibrating arms 9 rotations of drive of mud electric motor is carried out timing;
Wherein, as shown in Figure 4, be provided with a plurality of mud blades 10 of trembling on mud cake vibrating arm 9, a plurality of mud blades 10 of trembling are around mud cake vibrating arm 9 Spiral distributions;
Mud cake vibrating arm 9 is arranged on the below of the filter plate 8 of dewatering unit 1, and the one end with tremble mud electric motor 11 and be connected.
So can realize the automatic dump to dewatering unit 1, dump is convenient, saves the dump time.
As shown in Figures 2 and 3, be provided with mud storehouse 6 on mud storing unit 2, the mud cake of dewatering unit 1 output is delivered to mud storehouse 6 by travelling belt 7.
In the present embodiment, the quantity of the dewatering unit 1 that arranges on mud storing unit 2 is a plurality of.A plurality of dewatering units 1 can be every two be one group and share a sludge pump 3, can realize that so a plurality of sludge pumps 3 extract the work of mud simultaneously, a plurality of dewatering units 1 alternately uninterruptedly carry out mud press filtration work, can further improve desilting efficiency data.
The load-carrying of considering mud storing unit 2 is limited, preferably, in the present embodiment, two dewatering units 1 can be set on mud storing unit 2, makes two dewatering units 1 mud filter-press dehydration that hockets.
