Description

Technical Field

[0001] The utility model belongs to the technical field of soil pollution prevention and control, and particularly relates to a solidification and stabilization stirring device for heavy metal contaminated soil. Background Technique

[0002] By adding a solidification and stabilization agent to the contaminated soil, the toxic heavy metals in the soil are fixed by physical or chemical methods, or converted into forms with inactive chemical properties, thereby preventing the migration and diffusion of heavy metals in the environment and reducing their toxicity. The mixing and stirring device system in the equipment is the core part, which can ensure the full mixing of the solidifying agent or stabilizing agent with the contaminated soil and achieve a uniform solidification and stabilization effect. This mixing and stirring effect is the key step to achieve the goal of soil remediation.

[0003] In the prior art, some solidification and stabilization stirring devices for heavy metal contaminated soil have potential defects of poor stirring effect during use. Uneven stirring will lead to insufficient mixing of the agent and the soil, making it difficult to fully fix or stabilize the heavy metals. The heavy metal content in the treated soil is still relatively high, and it is difficult to achieve the expected remediation effect. At the same time, some solidification and stabilization stirring devices for heavy metal contaminated soil also have the defect of being difficult to accurately control the flow rate of the agent. Inaccurate control of the agent flow rate will lead to an imbalance in the mixing ratio of the soil and the agent. Some soil may have an excessive amount of the agent, while some soil may have an insufficient amount of the agent, resulting in uneven treatment effects. Content of the Utility Model

The output end of the first motor 202 penetrates to one side surface of the inner wall of the mixing tank 102 and is fixedly connected to a connecting rod 203. The connecting rod 203 is rotatably connected to one side of the inner surface of the support frame 201;

[0031] Among them, the first motor 202 is used to drive the connecting rod 203 to rotate synchronously.

[0032] The adjusting assembly 300 includes a feeding pipe 301 arranged on one side of the steel frame 101, and a discharge port 302 is fixedly connected to one end of the feeding pipe 301.

[0033] Among them, the feeding pipe 301 is used to convey the medicament, and the discharge port 302 is used to support other components in the adjusting assembly 300.

[0034] Specifically, the bearing assembly 100 further includes a sealing cover 103 hinged to one side of the outer surface of the mixing tank 102, and a ladder 104 is fixedly installed on one side of the outer surface of the steel frame 101.

[0037] In summary, the bearing assembly can keep the device stable during mixing, and at the same time can facilitate the staff to observe the internal situation of the mixing tank 102.

[0038] Embodiment 2

[0039] Referring to Figure 1 、 Figure 3 and Figure 4 , this is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides the structure of the mixing assembly 200 and an efficient mixing method.

[0044] During use, the first motor 202 is started to drive the connecting rod 203 to rotate synchronously. The connecting rod 203 drives the first bevel gear 204 and the first stirring rod 205 to rotate synchronously. Then, the first bevel gear 204 drives the third bevel gear 209 to rotate, so that the third bevel gear 209 drives the second bevel gear 207 to rotate. Thus, the second bevel gear 207 drives the connecting sleeve 206 and the second stirring rod 208 to rotate in the opposite direction, so as to achieve the effect of realizing bidirectional stirring through a single motor.

[0045] In summary, through the setting of the stirring assembly 200, the first motor 202 can drive the first stirring rod 205 and the second stirring rod 208 to rotate bidirectionally at the same time. While improving the stirring efficiency through bidirectional rotation, it also saves the operation cost of the equipment to a certain extent.

[0046] Embodiment 3

[0047] Referring to Figure 1 、 Figure 2 and Figure 5 , this is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides the structure of the adjusting assembly 300 and the method of adjusting the chemical agent flow rate.

[0048] Specifically, the adjusting assembly 300 further includes a protective cover 303 adaptively installed on one side surface of the discharge port 302, and a limiting groove 304 is formed on the surface of the protective cover 303.

[0049] Among them, the protective cover 303 is used to protect some components in the adjusting assembly 300.

[0050] Furthermore, the adjusting assembly 300 further includes a toothed ring 305 slidably connected in the limiting groove 304, and a rotating column 306 is fixedly connected to one side surface of the discharge port 302.

[0051] Among them, four groups of internal teeth and one group of external teeth are arranged on the surface of the toothed ring 305.

[0052] Preferably, the adjusting assembly 300 further includes an opening and closing plate 307 rotatably connected to the surface of the rotating column 306. A second motor 308 is adaptively installed on one side surface of the material conveying pipe 301, and a spur gear 309 is fixedly connected to the output end of the second motor 308.

[0053] Among them, the rotating column 306 is used to support the opening and closing plate 307. The number of the rotating column 306 and the opening and closing plate 307 is four. The teeth at one end of the four opening and closing plates 307 are respectively meshed with the four groups of internal teeth on the surface of the toothed ring 305. The second motor 308 is used to drive the spur gear 309 to rotate synchronously. The teeth of the spur gear 309 extend into the inside of the protective cover 303 and are meshed with one group of external teeth on the surface of the toothed ring 305.

[0054] During use, the material conveying pipe 301 is moved to a suitable position, the valve is opened to allow the medicament to flow to the discharge port 302. The staff remotely controls to start the second motor 308 to drive the spur gear 309 to rotate synchronously. Then, through the cooperation between the rotation of the spur gear 309 and one group of external teeth on the surface of the toothed ring 305, the toothed ring 305 is driven to slide in the limiting groove 304. At the same time, the four groups of internal teeth on the surface of the toothed ring 305 respectively drive the four opening and closing plates 307 to rotate around the rotating column 306, so as to adjust the angles of the four opening and closing plates 307, so as to achieve the effect of accurately adjusting the flow rate of the medicament during feeding.

[0055] In summary, through the setting of the adjusting assembly 300, the flow rate of the medicament during feeding can be accurately adjusted, so as to ensure that each unit of soil can obtain an appropriate amount of medicament treatment, thereby reducing unnecessary medicament waste, reducing the repair cost. Accurately adjusting the flow rate of the medicament during feeding also helps to achieve the uniform mixing of the medicament and the contaminated soil, so as to effectively exert the solidification and stabilization effect of the medicament.
