Embodiment 1

[0040] like Figure 1-10 As shown, a sludge press with distributed pressing units includes a lower platform 1 on which a plurality of groups of uprights 101 are installed to guide the sliding of the movable beam 2, and a plurality of groups of the uprights The movable beam 2 is installed on the movable beam 2, and the pressing unit 3 is penetrated in the movable beam 2. The vertical column 101 is also sleeved with a fixed beam 4, and the upper and lower ends of the fixed beam 4 are fixedly connected with adjusting nuts 401. The fixed beam 4 is limited on the upright column 101 by adjusting the nut 401 to provide structural guarantee for the orderly progress of the sludge pressing work. There is a working space, and a pressing hydraulic cylinder 7 is installed on the fixed beam 4. The pressing hydraulic cylinder 7 drives the pressing unit 3 to work to complete the sewage pressing of sludge. The pressing hydraulic cylinder 7 can also be other power drive devices;

[0041] The r...

Embodiment 2

[0045] like Figure 3-5 As shown, the lower platform 1 is provided with a water blocking frame 102, the water blocking frame 102 is arranged on the lower platform 1 and multiple groups cooperate with each other to form a rectangular frame, and the sewage formed by pressing is concentrated on the inner side of the water blocking frame 102, so the The pressing unit 3 is located on the inner side of the water blocking frame 102. The lower platform 1 on the inner side of the water blocking frame 102 is provided with a plurality of groups of water outlet holes 103 on the plane. The water outlet hole 103 is connected with the sewage pipeline 104, the sewage pipeline 104 is connected to the external drainage pipeline, the sewage formed by the sludge pressing is discharged from the water outlet hole 103 to the sewage pipeline 104, and finally the staff will install the external The drainage pipe is connected to the sewage pipeline to discharge the sewage produced by pressing in time. ...

Embodiment 3

[0048] like Figure 1-7 As shown, the pressing units 3 are distributed on the movable beam 2 in multiple groups, and the pressing unit 3 includes a filter cartridge 301, the filter cartridge 301 is fixedly connected to the movable beam 2, and the bottom of the filter cartridge 301 is installed There is a lower indenter 302, an upper indenter 303 is also arranged above the lower indenter 302, a working space is left between the upper indenter 303 and the lower indenter 302, and the upper indenter 303 is connected with the lower indenter 303. There are permeable holes 306 evenly distributed on the pressure head 302, and round holes 307 are evenly distributed on the filter cartridge 301. The permeable holes 306 and the round holes 307 are used to discharge the sewage generated during the sludge pressing. The head 303 is connected with the piston rod of the pressing hydraulic cylinder 7 which is arranged in the fixed beam 4. Each pressing unit 3 corresponds to a single pressing hy...

Abstract

The invention provides a sludge squeezer with distributed squeezing units, relates to the technical field of sludge dewatering, and aims to solve the problems of single structure, low dewatering speed and poor dewatering effect of an existing sludge filter press. Comprising a lower platform, multiple sets of stand columns are installed on the lower platform, a movable beam is installed on the multiple sets of stand columns, a squeezing unit is arranged in the movable beam in a penetrating mode, the stand columns are further sleeved with a fixed beam, and the upper end and the lower end of the fixed beam are fixedly connected with adjusting nuts. The fixed beam is located above the movable beam, a working space is reserved between the fixed beam and the movable beam, a squeezing hydraulic cylinder is installed on the fixed beam, the round hole is formed in the side wall of the filter cylinder and used for draining water, and compared with a membrane filter press which is only provided with a water draining hole in a filter plate at the end of the filter cylinder, the water draining efficiency is greatly improved; in the sludge squeezing process, filtrate can be discharged without hindrance when reaching the side wall of the filter cylinder through the mud cake interlayer channel, so that the difficulty of filtrate discharge is reduced.

Description

technical field [0001] The invention relates to the technical field of sludge dewatering, in particular to a sludge press with distributed pressing units. Background technique [0002] The filter press is the main equipment used for pressure dewatering of sludge. At present, the commonly used sludge dewatering treatment includes belt filter press, plate and frame filter press, diaphragm filter press, etc. In the belt filter press, the sludge is sandwiched between two layers of filter cloths, and goes around on multiple rollers, and the sludge is filtered and dehydrated by the pressure of the rollers and the tension of the filter cloth. Its working efficiency is high, but the moisture content of sludge after dewatering treatment is high, which is 80~85%, which is far from meeting the treatment requirements. In the plate and frame filter press, the filter plate and the filter frame are alternately stacked on two parallel support beams. The filtration pressure is provided by ...
