When mobile, the shape of filter plate 15 will not be made to receive extrusion deformation because of the gravity of sludge, and pushing away of moving right of sludge
Power can open the outlet of sewer 16 on right side, and sludge is discharged from outlet of sewer 16, complete sewage and sludge
Separation, the sewage of the novel environment friendly of the sewage treatment field desilts equipment when the sludge bulking to large volume is stirred, in dirt
Mud processing main body 1 is internally provided with teeter chamber 19 and pulverizing chamber 21, and the sewage containing big sludge is poured into Treatment of Sludge in this way
The inside of main body 1 can crush big sludge by pulverizing chamber 21 first, then by teeter chamber 19 to broken sludge
It is stirred so that sludge becomes soft, the sewage contained in sludge can be squeezed out in the process below in this way,
Simultaneously can by the sewage in sludge can by squeeze flow out, more sewage can be handled, facilitate by
Sludge and sewage are separated.
Working principle: when the sewage of the novel environment friendly using the sewage treatment field desilts equipment, the dirt is first checked for
The sewage of the novel environment friendly of water treatment field desilts equipment inner body and whether structure is completed, and is then familiar with sewage treatment neck
The sewage of the novel environment friendly in domain is desilted and is come into operation again inside equipment after installation and operation process, in use, starting simultaneously the first
One motor 7, the second motor 8, first motor 7 drives the second screw rod 6 to be operated, between the second screw rod 6 and the first screw rod of upper end 3
Chain 22 is arranged with to be attached, in this way the second screw rod 6 operate during will by chain 22 drive the first screw rod 3 into
Row running, the second motor 8 drive stirring rod 18 to be rotated, 7 slidings being arranged on such first screw rod 3 and the second screw rod 6
Block 5 can be moved in the opposite direction, and sludge is then poured into Treatment of Sludge main body 1 from the sludge import 2 of upper end
Inside, when by pulverizing chamber 21, the sludge of large volume is crushed by the broken block 4 being arranged on sliding shoe 5, then will be dirty
Teeter chamber 19 can be flowed downwardly by the outlet 20 of lower end after the completion of mud is broken, pass through stirring for 19 inner rotation of teeter chamber
It mixes bar 18 to be stirred the sludge being crushed, so that sludge becomes soft, under then passing through the sewage for mixing sludge
The dispatch tube 17 at end is transmitted to inside the sludge filtration case 10 on right side, and the water mixed in sludge is flowed by the filter plate 15 of lower end
It to the lower end of sludge filtration case 10, is flexibly connected between the left side and dispatch tube 17 of sludge filtration case 10, sludge passes through
Dispatch tube 17 can take out dispatch tube 17 from the left side of sludge filtration case 10 when being all flowed into the inside of sludge filtration case 10
Out, the opening in 10 left side of sludge filtration case is closed, then starts first hydraulic cylinder 9, first hydraulic cylinder 9 passes through lower end
Connecting rod 24 drives the first pressing plate 11 to move down, and the sliding slot 12 by the first pressing plate 11 in two sides moves down, and thus may be used
To press the sludge inside sludge filtration case 10 downwards, so that the sewage contained in sludge is downward by the first pressing plate 11
It is squeezed, subsequently starts second hydraulic cylinder 25, so that second hydraulic cylinder 25 drives the first pressing plate 11 to be moved to the right, this
Sample sludge will be moved to the right, and the sewage contained in sludge in the process of moving can pass through the filter plate 15 of lower end
It is flowed into the lower end of sludge filtration case 10, and the thrust that sludge moves right can open the sludge outlet 14 on right side, make
Obtaining sludge can discharge from sludge outlet 14, and the sewage of the lower end siltation of last sludge filtration case 10 can be gone out by sewage
Mouthfuls 16 discharge, this completes the separation of sewage and sludge, so as to complete the novel environment friendly of the sewage treatment field
Sewage desilts installation and operation process inside equipment, and here it is the works that the sewage of the novel environment friendly of the sewage treatment field desilts equipment
Make principle.
Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art
Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into
Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all
