[0002] Soil remediation mixing kettle is a kind of equipment specially used in soil remediation process. It mainly mixes soil with remediation agents or other remediation materials through mixing and reaction to achieve the purpose of remediating contaminated or damaged soil.

[0003] For example, Chinese patent publication number CN221536478U discloses a soil remediation mixing kettle, comprising a kettle body, wherein a crushing and filtering assembly and a stirring assembly are movably connected inside the kettle body, wherein the crushing and filtering assembly comprises a filter tube and a crushing mechanism, wherein the stirring assembly comprises a stirring blade, and wherein the upper end of the kettle body is fixedly connected to a spray assembly, wherein the spray assembly comprises a water pipe. In the utility model, after the soil enters the filter tube, the soil is filtered through filter screens 1 and 2, so that larger particles roll into the crushing box through guide plate 1, and the larger particles are crushed by the crushing mechanism. After being crushed, the larger particles return to the interior of the kettle body through guide plate 2 and the connecting pipe. In this way, the crushing and filtering assembly can not only filter the soil, but also crush the larger particles after filtering.

[0004] The above patent has the following problems:

[0005] This patent has some shortcomings when used. For example, when the device is screening soil, the wet soil may clog the filter, requiring manual cleaning of the clogged filter, which is time-consuming. Furthermore, after the device is stirred, some soil may remain inside the device and not be completely discharged. The soil remaining inside the device for a long time may produce bacteria, affecting the next use. In view of this, we propose a soil remediation mixing kettle. Utility Model Content
