Oily sludge drying and curing treatment device

By setting a pushing structure inside the mixing tank, the sludge is moved by using a rotating shaft and a pushing arc frame. The pushing arc frame is also set on the outside of the mixing rod, which solves the problems of slow sludge flow and poor mixing effect, and achieves rapid discharge and uniform mixing, thus improving the efficiency of the device.

AI Technical Summary

Technical Problem

In existing oily sludge drying and solidification treatment devices, the sludge is relatively viscous and flows slowly, resulting in poor mixing effect and seriously affecting the efficiency of use.

Method used

A pushing structure, including a rotating shaft and a pushing arc frame, is set inside the mixing tank. The sludge is moved by the fan blades, and a circumferentially oscillating pushing arc frame is set on the outside of the mixing rod. In conjunction with the rotation of the mixing rod, the sludge is quickly discharged and the solidifying agent is evenly sprayed.

Benefits of technology

It increases the flow rate of sludge, shortens the residence time of sludge in the mixing tank, enhances the mixing effect of sludge and solidifying agent, and improves the efficiency of the equipment.

Abstract

The utility model relates to the technical field of sludge treatment, in particular to an oily sludge drying and curing treatment device which comprises a stirring barrel, a feeding hole is formed in the left end of the top surface of the stirring barrel, a discharging hole is formed in the right end of the bottom surface of the stirring barrel, and a stirring rod is movably mounted on the inner side of the stirring barrel through a bearing; the right end of the stirring rod is fixedly connected with a belt pulley; a pushing structure is mounted on the inner side of the stirring barrel and comprises a rotating shaft, and the rotating shaft is movably mounted on the inner side of the stirring barrel through a bearing. The fan blades are arranged on the lower side of the feed port and can push sludge to move rightwards during rotation so as to be conveniently and quickly discharged through the discharge port, and the material pushing arc frame swinging circumferentially is arranged on the outer side of the stirring rod and can be immersed in the sludge during rotation and stir and push the sludge towards the position perpendicular to the rotation direction of the stirring rod, so that the sludge can be quickly discharged through the discharge port. The stirring effect on the sludge is ensured, and the auxiliary pushing effect on the sludge is improved.
