Embodiment 1

[0062] In the sludge fixing device 400, the side wall of the fixed outer mold 402 is equipped with four auxiliary oil cylinders 401 uniformly arranged, and the four auxiliary oil cylinders 401 adopt the same type of oil cylinder, and the use of the same type of oil cylinder makes the fixed outer mold 402 rise or fall. The lower port of the outer mold 402 is always fixed on the horizontal plane, so that the sludge on the lower filter cloth conveyor belt 209 can be wrapped up as a whole.

[0063] Four main oil cylinders 501 are installed on the frame 100, and the main oil cylinders 501 also adopt the same type of oil cylinders. The multiple main oil cylinders 501 make the fixed upper mold 403 receive a greater force, so that the force of squeezing the sludge is greater .

[0064] Both the main oil cylinder 501 and the auxiliary oil cylinder 401 are connected with a hydraulic station 600 , and the hydraulic oil inlet pipeline of the auxiliary oil cylinder 401 and the main oil cyl...

Embodiment 2

[0067]The fixed outer mold 402 can be made of 304 stainless steel, which not only can withstand greater working pressure, but also can effectively reduce the corrosion of the fixed outer mold 402 and prolong the service life of the fixed outer mold 402 . The fixed upper mold 403 is arranged in the fixed outer mold 402, and the two are clearance fit, and the fixed upper mold 403 can slide freely. The fixed upper mold 403 and the fixed outer mold 402 have a gap fit. In order to prevent the sludge from being extruded from the slits in the gap fit during the extrusion process, an O-shaped mold for preventing sludge leakage is also installed on the outer wall of the fixed outer mold 402. Sealing ring, to improve the sealing between its fixed outer mold 402 and fixed upper mold 403. When the fixed outer mold 402 lowers the fixed sludge, the fixed outer mold 402 is lowered to the set position and stops the lowering action; the fixed upper mold 403 moves downward for several seconds t...

Embodiment 3

[0070] The shaped part 304 is in the shape of a ring, and the shaped part 304 can be made of 304 stainless steel to reduce the corrosion of the shaped part 304 . The side of the shaped part 304 is connected to the output end of the pre-compression cylinder 306. The pre-compression cylinder 306 can be a compressed air cylinder or an oil cylinder. In this embodiment, the pre-compression cylinder 306 is an oil cylinder. The movement of the pre-pressing cylinder 306 drives the shaped part 304 to rotate around the rotating shaft 305 . In the specific working process, the rotating shaft 305 is installed on the frame 100, and the rotating shaft 305 is installed opposite to the pre-pressing cylinder 306. Under the action of the hydraulic oil, the output end of the pre-pressing cylinder 306 moves upwards, thereby driving the shaped parts 304 rotates around the rotating shaft 305, so that there is a certain distance between the shaped part 306 and the lower filter cloth conveyor belt 20...

Abstract

The invention relates to sludge dewatering equipment. The sludge dewatering equipment comprises a rack, a sludge conveying device mounted on the rack and used for conveying the sludge to a next execution station, a sludge shaping device arranged on the rack and used for shaping the sludge on the sludge conveying device into a set shape, a sludge fixing device used for receiving and fixing the sludge conveyed by the sludge conveying device and positioned in the rack, and a sludge extruding device mounted on the rack and used for extruding and dewatering the sludge in the sludge fixing device. The water content of sludge discharged after sludge dewatering is low, continuous operation is achieved, the equipment investment is small, and the operation cost is low.

Description

technical field [0001] The invention relates to the technical field of sludge dewatering in the environmental protection industry, in particular to a sludge dewatering device. Background technique [0002] Sludge dewatering equipment is a continuous operation of sludge treatment equipment, mainly divided into plate and frame filter press, belt filter press, centrifugal dewatering machine and stacking screw dewatering machine. [0003] The plate and frame filter press is pressed into the plate and frame to filter, extrude and dehydrate. The whole process of plate and frame compression feeding, frame unloading, filter cloth washing, etc. is automatically operated. The moisture content of the sludge is low, and the moisture content can reach 60. % or less, but the equipment investment is large, the floor area is large, the supporting equipment is many and complex, and it cannot run continuously; the belt filter press is a comprehensive dehydration machine that uses gravity dehy...
