Description

Technical Field

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

[0002] Desulfurization wastewater sludge treatment refers to the process of treating sludge containing sulfide, oxide, limestone and other impurities generated during the desulfurization process. The wastewater sludge first needs to be dehydrated to reduce the moisture content to a certain level to reduce the volume and weight. The wastewater from the sludge may contain a large amount of alkaline or acidic substances. The wastewater needs to be neutralized to make its pH value close to neutral to reduce its harm to the environment.

[0003] At present, the existing desulfurization wastewater sludge treatment devices on the market usually need to remove the moisture in the sludge first, and then neutralize the wastewater after all the sludge is dehydrated, and finally take the dehydrated sludge out of the equipment. This operation process is relatively cumbersome and cannot be carried out simultaneously. Utility Model Content

[0028] In this embodiment, when the fixed column 2 rotates, the extrusion plate 3 and the material-discharging plate 5 are controlled to move synchronously, and when the pulley 11 at the bottom end rotates, it drives the first bevel gear 13 to rotate, and the first bevel gear 13 drives the second bevel gear 15 meshing on the other side to rotate. When the second bevel gear 15 rotates, the reciprocating screw 19 is controlled to rotate through the transmission shaft 14, and when the reciprocating screw 19 rotates, it drives the movable sleeve 20 to reciprocate and rise and fall linearly. When the extrusion plate 3 is displaced from the upper position to the lower position with the rotation of the fixed column 2, the tray 6 is lifted to the highest point, so that the mud and water entering from the feeding port 27 are clamped by the extrusion plate 3 and the tray 6, so that the sludge and water in the mud and water are separated, and the water enters the water tank 7 below the processing box 1, and the sludge is pushed to the position of the guide plate 24 by the continuously displacing material-discharging plate 5, so that the mud and water separation can be achieved, and the dehydrated soil can be discharged.
