Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, and in particular to a chemical dosing device for remediating organically polluted soil. Background Technology

[0002] Chemical oxidation technology is one of the main technologies for treating organic and compound contaminated soils. It involves adding chemical oxidizing agents to the soil, which react with the pollutants in a redox reaction, degrading or transforming the pollutants into less toxic and less mobile pollutants. Chemical oxidation technology has the advantages of high efficiency and low cost, and can effectively treat compound contaminated soils formed by various organic and compound pollutants, making it very suitable for my country's needs for contaminated soil remediation.

[0003] Chinese Patent CN216911511U discloses an improved dosing device for the remediation of organic and compound contaminated soil. The device includes a base frame, on the upper surface of which are arranged four raw material storage tanks, a mixing tank, and a temporary storage tank. Each of the four raw material storage tanks is connected to a mixing tank via a pipeline transmission mechanism. The mixing tank is connected to the temporary storage tank via a second pipeline transmission mechanism. The temporary storage tank is connected to a sprayer via a third pipeline transmission mechanism. A stirring mechanism is installed on the top of each of the four raw material storage tanks, mixing tanks, and temporary storage tanks. The activated reagents are stored in the temporary storage tank and then sprayed onto the contaminated soil in different directions through a three-part pipe and a nozzle, ensuring thorough mixing of the reagents and the contaminated soil. This improves the soil remediation efficiency. Furthermore, the large-capacity tanks can store a large amount of reagents, allowing for continuous spraying and the remediation of large quantities of soil at once.

[0004] Existing chemical dosing devices for organic contaminated soil remediation lack a leakage collection structure. If a leakage occurs during the connection between the pipeline and the tank, the chemical may seep into the soil below the base, causing contamination and reducing the practicality of the chemical dosing device for organic contaminated soil remediation.

The outer walls of the insulation shell 4 and the temporary storage tank 7 are spaced to form a filling cavity, which can be filled with heat-resistant and low-temperature-resistant insulation materials. This allows for easy filling of insulation materials according to the ambient temperature of the device, improving the temporary storage of the agent and enhancing the structural integrity of the device. The guide channel 101 and the collection assembly work together to facilitate the collection of leaked agents. Furthermore, the guide channel 101 is tilted towards the end of the collection box 2, allowing the leaked agent to flow into the collection box 2 through the guide channel 101, thus improving the collection effect of the leaked agent.

[0017] Further explanation: Each of the four raw material storage tanks 3, mixing tank 6, and temporary storage tank 7 is equipped with a feed pipe 14; each of the four raw material storage tanks 3, mixing tank 6, and temporary storage tank 7 is connected to a stirring assembly; each stirring assembly includes a protective box 8, a motor 801, a rotating rod 802, a stirring blade 803, and a mounting cover 804; the motor 801 is housed inside the protective box 8, connected to the rotating rod 802, and the stirring blade 803 is connected to the outer wall of the rotating rod 802; the protective box 8 is connected to the mounting cover 804, and the connection is detachable. The stirring blades 803 of each assembly are connected to the interior of each of the four raw material storage tanks 3, mixing tank 6, and temporary storage tank 7, facilitating the stirring of the reagents within the tanks.

[0018] Example 2: Figure 1 and Figure 4 As shown, the present invention proposes an organic polluted soil remediation dosing device. Based on the above embodiments, this embodiment also details the specific components and coordination methods of multiple sets of pipeline transmission components and feeding components.

[0019] To further explain, each set of pipeline transmission components a includes a liquid pump a5, a flow meter a501, a valve a502, and a long pipe a503; the output end of the liquid pump a5 is connected to the long pipe a503, and the flow meter a501 and the valve a502 are installed on the long pipe a503; each raw material storage tank 3 is connected to the mixing tank 6 through pipeline transmission components a; the mixing tank 6 is connected to pipeline transmission component b, pipeline transmission component b is connected to the temporary storage tank 7, the temporary storage tank 7 is connected to pipeline transmission component c, pipeline transmission component c is connected to the hose 13, and the hose 13 is equipped with a switch valve and connected to a nozzle. Pipeline transmission component b includes a pump b, a long pipe b, a flow meter b, and a valve b; the pump b is connected to the mixing tank 6, the output end of the pump b is connected to the long pipe, the long pipe is connected to the temporary storage tank 7, and the long pipe b is equipped with a flow meter b and a valve b; pipeline transmission component c includes a pump c, a long pipe c, a flow meter c, and a valve c; the pump c is connected to the temporary storage tank 7, the output end of the pump c is connected to the long pipe c, the long pipe c is connected to the hose 13, and the long pipe c is equipped with a flow meter c and a valve c; sodium sulfate reagent is added to two raw material storage tanks 3, sodium hydroxide reagent is added to another raw material storage tank 3, and finally water is added to the last raw material storage tank 3. The motor 801 of the stirring mechanism is started. The rotating rod 802 is driven to rotate, causing the stirring blade 803 to stir the raw materials in the raw material storage tank 3. Then, different raw materials are transported into the mixing tank 6 through the pipeline transmission component a for mixing, stirring and activation. During the transportation through the pipeline transmission component a, the ratio of each raw material can be controlled by the flow meter a501 and the valve a502. The quantitative adjustment can be made according to different soil conditions. After stirring and activation, the agent is transported to the temporary storage tank 7 through the pipeline transmission component b, and then sprayed out from the hose 13 through the pipeline transmission component c. The hose 13 can be supported by a triangular bracket and its height can be adjusted. The nozzle sprays the agent onto the soil, so that the agent is fully mixed with the contaminated soil, thereby improving the soil remediation efficiency.

[0020] Further explanation: The base plate 1 is connected to the base frame plate 9, and the base frame plate 9 is connected to the feeding assembly; the feeding assembly includes feeding support rods 10, moving blocks 1001, connecting blocks 1002, sliders 1003, and foot pedals 1004; there are two feeding support rods 10, each with a moving block 1001 at its upper end, each moving block 1001 connected to a connecting block 1002, and each feeding support rod 10 connected to a slider 1003 on one side; both feeding support rods 10 are connected to the foot pedals 1004, which are made of anti-slip patterned steel plates; the base plate 1 is connected to support rods 11, and the support rods 11 are connected to connecting slide rods 12, which have six sets of through holes, with two through holes in each set. A set of through holes are respectively connected to the connecting blocks 1002. Each connecting block 1002 is provided with a mounting hole, and the six sets of through holes are respectively set on both sides of the four raw material storage tanks 3, mixing tanks 6 and temporary storage tanks 7. When the temporary storage tank 7 needs to be fed, the feeding component is adjusted to one side of the temporary storage tank 7. The mounting holes and through holes of the connecting blocks 1002 correspond to each other, and a fixing pin is used to pass through to facilitate the auxiliary fixing effect. Then, the lower end of the feeding component is straightened by the staff to ensure that the staff on the feeding component can stably feed the temporary storage tank 7. When the raw material storage tanks 3 and mixing tanks 6 need to be fed, the feeding component is adjusted to the corresponding position so that the operation is the same as the feeding operation of the temporary storage tank 7, which facilitates the feeding of the organic polluted soil remediation dosing device.

[0021] The working principle of this utility model is as follows: During soil remediation, the organic polluted soil remediation dosing device connects four raw material storage tanks 3 and mixing tanks 6 via four sets of pipeline transmission components a; connects mixing tank 6 and temporary storage tank 7 via pipeline transmission component b; and connects temporary storage tank 7 and hose 13 via pipeline transmission component c. However, in the event of a leak at the connection point, a guide channel 101 is installed on the base plate 1. The guide channels 101 are distributed below the connection point. The inclined angle of the guide channels 101 allows the chemicals to flow naturally into the collection tank 2, preventing accumulation. Simultaneously, the inner wall of the guide channels 101 is coated with polytetrafluoroethylene (PTFE), which does not react with acidic or alkaline chemicals and reduces chemical adhesion, ensuring that most of the leaked chemicals flow smoothly into the collection tank 2, avoiding... The leak-proof agent seeps into the bottom of the base plate 9, and the staff can then promptly handle the collected leaks based on the liquid level in the collection tank 2 to prevent overflow. Before use, staff place adsorbent materials, such as activated carbon and adsorbent resin, into the collection tank 2. The lower layer is a certain thickness of adsorbent resin, such as macroporous anion exchange resin, which adsorbs harmful ions from the agent, while the upper layer is a certain thickness of activated carbon, which adsorbs volatile organic compounds from the agent. The two layers work synergistically to purify the leaked agent, achieving preliminary treatment. The adsorbent materials need to be cleaned and replaced regularly to prevent secondary pollution. This improves the practicality of the organic polluted soil remediation dosing device. Content not described in detail in this manual is prior art known to those skilled in the art.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
