Description

Technical Field

[0001] The utility model belongs to the technical field of soil remediation, and in particular relates to a soil remediation processing device. Background Art

[0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil, reducing their concentration to an acceptable level, or converting toxic and harmful pollutants into harmless substances.

[0003] For example, Chinese patent publication number CN219292031U discloses a soil remediation treatment device, which belongs to the field of soil remediation and includes a mixing box with an open top, a liquid inlet pipe, and a liquid outlet pipe. The liquid inlet pipe is mounted on the side wall of the mixing box, and the liquid outlet pipe is mounted at one end of the liquid inlet pipe, and the liquid outlet pipe is arranged inside the mixing box. A screen drum with openings at both ends is slidably mounted inside the mixing box. A drive assembly for driving the screen drum to perform horizontal lateral movement is mounted on the mixing box. A screen is hinged inside the screen drum, and an electric push rod is hinged on the side wall of one side of the screen drum, and the telescopic end of the electric push rod is hinged on the screen. The present application overcomes the shortcomings of the prior art and automatically cleans solid particles on the screen through the interaction between the mixing box, screen drum, screen, electric push rod, filter plate, mounting plate, rotating disk, drive rod, drive block, moving rod, drive motor, and guide rod. Manual cleaning is not required, which reduces labor, saves time, and improves work efficiency.

[0004] The above patent has the following problems:

[0005] This patent has some shortcomings when used. For example, when the device screens the soil, some soil will clump together, which will affect the efficiency of the soil screening. At the same time, the device is not convenient for discharging the soil from the second discharge port, which easily causes some soil to remain in the corner of the bottom of the mixing chamber, requiring manual cleaning by staff, which is quite inconvenient. In view of this, we propose a soil remediation and treatment device. Utility Model Content

[0006] The purpose of the present invention is to provide a soil remediation device to solve the problems raised in the above background technology.

[0007] In view of this, the present invention provides a soil remediation device, comprising:

At this time, the sprayed repair liquid will fall on the soil, and the auger can mix the soil and the repair liquid. Under the action of the filter plate, the soil can be prevented from entering the water tank. The repaired soil will then be discharged and collected from the discharge port of the discharge pipe.

[0014] When it is necessary to clean the larger granular impurities on the top of the screen plate, the driving assembly is set up to drive the placement barrel to move upward, so that the annular frame is moved out of the annular groove, so that a certain distance is generated between the placement barrel and the annular frame. Then, the annular frame can be moved upward, and the annular frame will drive the screen plate to move upward, so that the annular frame is pulled out from the two cylinders. Then, the annular frame can be removed from the fixing ring together with the screen plate, and the larger granular impurities in the annular frame can be cleaned.
