AI Technical Summary

Technical Problem

In existing in-situ sludge solidification treatment devices used in river remediation construction, the solidification agent has difficulty penetrating into the sludge quickly, resulting in a long mixing process, high energy consumption, and uneven agent penetration, which affects the sludge solidification effect and construction efficiency.

Method used

The injection space is formed by using mud-dividing plates and mud-supporting plates. Combined with the design of the spraying component's water nozzle and rotating base plate, it ensures that the solidified agent can quickly penetrate deep into the sludge. Through the synergistic effect of the mud-dividing plates and mud-supporting plates, a stable injection space is formed, and the uniform spraying and mixing of the agent is achieved by using the cooperation of the water nozzle and rotating base plate.

Benefits of technology

It improves the mixing effect of sludge and solidification agent, reduces mixing time and energy consumption, enhances the construction quality and overall stability of sludge solidification, and avoids the environmental pollution risks caused by uneven agent penetration.

Abstract

The utility model discloses a sludge in-situ curing treatment device for river regulation construction, which comprises a main shaft provided with a protective sleeve, a pesticide spraying component arranged at the bottom of the protective sleeve, a plurality of groups of stirring devices arranged on the main shaft, sludge separating plates symmetrically arranged on adjacent stirring blades of the stirring devices, and sludge supporting plates arranged on the sludge separating plates and distributed oppositely. The mud separating plate and the mud supporting plate are distributed in a linear mode in the height direction of the main shaft, a medicine injection space is formed by the mud separating plate and the mud supporting plate, and the medicine spraying assembly is provided with a liquid medicine spray head matched with the medicine injection space. Sludge is divided by the sludge dividing plates welded on the stirring blades in the rotating direction of the stirring blades, then the sludge is supported by the sludge supporting plates, finally, a chemical injection space is formed behind the sludge supporting plates, the sludge is divided into a space at the position, and at the moment, a curing chemical is sprayed to the sludge space from the chemical spray head after passing through the corrugated pipe from the chemical inlet pipe; and the curing agent is sprayed deep in the sludge, so that the agent mixing effect is improved.
