Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a filter press device. Background Art

[0002] In the process of seawater desalination, the precipitated sludge needs to be dried to remove moisture from the sludge and facilitate subsequent sludge treatment. The general method for removing moisture from the sludge is to use a sludge filter press to drain the water. However, the existing filter press devices directly send the precipitated sludge into the sludge filter press device. The sludge without any pretreatment has a high moisture content and a poor filter press effect. At the same time, when the existing filter press device discharges the treated sludge, the bottom of the filter press plate is prone to sludge sticking to it, and when the push plate cannot clean up all the sticky sludge, more and more sludge will stick to the filter press plate, affecting the sludge filter press efficiency.

[0008] Furthermore, the mud outlet pipe of the water filter box passes through the box body and extends to one side of the pressure plate groove.

[0009] Furthermore, the first bracket is slidably connected to the first protrusion at the bottom of the pressure plate groove through a rotating column, and the second bracket is engaged with the second protrusion at the bottom of the pressure plate groove.

[0010] Working principle and beneficial effects:

[0011] When using the device, the sludge precipitated after seawater desalination is poured into the filter water tank, the water in the sludge will flow out from the filter screen, and the sewage will be discharged from the outlet pipe; the sludge inside the filter water tank will be discharged from the sludge outlet pipe to the pressure plate groove, the first hydraulic rod is started, the first hydraulic rod drives the pressure plate to further press out the water in the sludge, and then the third hydraulic press is started, the third hydraulic press rotates the pressure plate groove along the first protrusion by a certain angle, and then the motor is started, the motor drives the rotating shaft to rotate, so that the half gear is engaged with the gear groove on the moving rod, the moving rod knocks the pressure plate groove upward, the sludge after filtration and pressure is shaken off from the filter press tank, and then the second hydraulic rod is started to push the remaining sludge out with the push plate.

[0012] The utility model can accelerate the outflow of water in the sludge during filter pressing by first processing the water in the sludge. After the sludge is filtered, the motor drives the semi-gear to move, driving the transfer rod to knock the pressure plate groove upward, so that the sludge stuck on the filter press plate is shaken off, and the push plate is convenient for pushing the sludge inside the filter press groove to reduce the residual sludge on the filter press groove, which can effectively prevent more and more sludge from sticking to the filter press groove and affecting the processing efficiency of the sludge.
