Description

Technical Field

[0001] The utility model relates to the technical field of soil remediation dosing, and particularly relates to an automatic dosing device for chemical oxidation soil remediation. Background Technique

[0002] The chemical oxidation technology uses the strong oxidizing property of oxidants to destroy target organic substances, so that organic pollutants are completely mineralized or transformed into low-toxic and easily biodegradable intermediate products. The most commonly used oxidants include potassium permanganate, ozone, Fenton's reagent and persulfate. Sometimes, in order to improve the remediation treatment degree of organic contaminated soil, a method of mixing multiple types of oxidation agents is usually adopted. However, the dosage of oxidation agents must be controlled during this process. Therefore, the addition amount and addition speed of different oxidation agents are particularly important.

[0003] In order to facilitate the addition of multiple types of oxidation agents, a dosing device is designed. However, in the existing dosing devices, generally, the required addition amount is calculated in advance before dosing. That is to say, it is difficult to flexibly adjust and control the addition amount and addition speed during the actual dosing process, resulting in problems such as excessive or too fast addition of some types of oxidation agents, so that the mixing of multiple types of oxidation agents is uneven, and ultimately the subsequent remediation effect of the agent on organic contaminated soil is affected.

[0004] Therefore, it is very necessary to invent an automatic dosing device for chemical oxidation soil remediation to solve the above problems. Content of the Utility Model

A dosing assembly that can control the dosing amount is longitudinally detachably inserted into the jacks 10. Removable extraction assemblies that can control the extraction amount of the medicament are installed at the positions on the outer side walls of both sides of the mixing tank 1 that are adapted to the dosing assembly. A transmission inclined pipe 16 that can control the flow rate is connected between the dosing assembly and the extraction assembly. One end of the transmission inclined pipe 16 is connected to the top of the side wall of the dosing assembly, and the other end of the transmission inclined pipe 16 is connected to the bottom of the side wall of the extraction assembly. The dosing assembly and the extraction assembly are similar to syringes, and the actual extraction amount or discharge amount can be controlled by controlling the pushing amount.

[0024] The dosing assembly includes a dosing pipe 13 detachably longitudinally inserted into the jacks 10, a dosing cylinder 12 installed at the top of the dosing pipe 13, a piston block 18 longitudinally slidably passing through the dosing cylinder 12, a push rod 19 arranged at the top of the piston block 18, and a push plate 20 arranged at the top of the push rod 19.

And various types of oxidizing agents entering the mixing tank 1 through the flow guiding cover 2 are evenly mixed under the mixing and stirring of the stirring blade 6, and finally discharged from the mixing tank 1 through the discharge pipes 7 and sprayed or added to the organic polluted soil for restoration use.
