Description

Technical Field

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

[0002] During the industrial and agricultural production process, a large amount of silt is generated and accumulated, such as at the bottom of fish ponds and lakes. If these silts undergo processing, filtration, solidification and other processes, they can be turned into treasure. The reprocessed and solidified silt can not only be used to plant grass and flowers, but also to build roadbeds and road slopes. After pretreatment, it can be used in roadbed backfill, pavement bricks, premixed mortar and other building materials. It can replace some raw materials with higher carbon emissions, achieve synergistic efficiency in pollution reduction and carbon reduction, and make important contributions to ecological environmental protection and the development of a regenerative economy.

[0003] After searching, a Chinese patent discloses a sludge solidification pretreatment device (authorization announcement number CN220642865U), which includes a base, support legs are fixedly connected to both sides of the upper surface of the base, and the tops of the support legs are fixedly connected to connecting frames. The adjacent surfaces of the two connecting frames are provided with a conveying mechanism, and one end of the conveying mechanism is provided above the solidification box. In the present utility model, although the patented technology can drive the conveying shaft to rotate by starting the motor, thereby causing the conveyor belt to convey the sludge, and the water in the sludge is filtered through the filter holes, when the sludge passes through the connecting plate, the connecting plate can pull the sludge apart, so that the water carried in the sludge can be fully filtered, and then the sludge is sent into the solidification box, and the heating plate heats the solidification box, so that the residual water in the sludge can be evaporated, which is convenient for subsequent solidification, thereby solving the problem that it takes a long time to dry the water inside the sludge during the sludge drying process.

[0004] However, the above-mentioned device still has some shortcomings in actual use. The most obvious one is that the sludge solidification pretreatment device uses a conveyor belt to transport the sludge, which can easily cause the sludge to slip from the conveyor belt and fail to achieve the purpose of transportation. In addition, the overall structure of the above-mentioned device is large, which makes it inconvenient in actual use and is not easy to apply to the mud collection site for treatment.

[0039] Working principle: First, move the transport vehicle 1 to the mud collection site, then use the connecting flange to connect the discharge pipe to the output end of the external sludge pump. When the sludge needs to be pre-treated, the cylinder 6 can be started by the external control device. With the extension and contraction of the piston rod of the cylinder 6, the water pressure plate 9 can be driven to move downward, and used in conjunction with the butterfly plate 11, it can speed up the dehydration operation of the sludge and improve the sludge pretreatment efficiency. In the above structure, the sludge is directly transported to the interior of the pretreatment tank 3 through the discharge pipe. Compared with the traditional conveyor belt transportation method, this transportation method is more reliable, and the entire device is small in size and is transported by the transport vehicle 1;

Then, the servo motor 14 can be started, and the rotation of the output shaft of the servo motor 14 can drive the butterfly plate 11 to flip, so that the squeezed sludge blocks fall into the interior of the mixing box 2;

[0041] When the sludge blocks after squeezing out the water enter the mixing box 2, a curing agent or a dehydrating agent can be added to the mixing box 2 through the feed port 8, and the rotation of the output shaft of the servo motor 2 5 can drive the stirring blade 7 to operate to improve the mixing effect of the curing agent and the sludge blocks, and further achieve an ideal sludge solidification state for subsequent processing.
