Description

Technical Field

[0001] This utility model relates to the field of contaminated soil remediation, and in particular to a rinsing device for soil pollution remediation. Background Technology

[0002] Soil leaching equipment is a rapidly developing and highly efficient remediation technology in recent years. It primarily uses chemical leaching to separate pollutants from the soil and is suitable for treating sites contaminated with heavy metals, organic matter, and complex contamination. The specific steps involve adding a specific leaching agent (such as chelating agents, acids, or surfactants) to the contaminated soil, causing the pollutants to transfer from the solid phase to the liquid phase, followed by solid-liquid separation to remove the pollutants. However, existing solid-liquid separation methods mainly rely on filters. In practical applications, solid particles mixed in the leaching agent easily clog the filters, affecting the separation efficiency. Therefore, we propose a soil leaching device for soil remediation. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is that existing rinsing equipment is prone to clogging when separating solid and liquid phases.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a leaching device for soil pollution remediation, which includes a sedimentation tank for settling the separated leaching agent, a separation component for separating the solid phase and liquid phase in the leaching agent, including an inclined separation tube, which is provided with an inlet, a solid phase outlet and a liquid phase outlet connected to the sedimentation tank.

[0005] As a preferred embodiment of the leaching equipment for soil pollution remediation of this utility model, the solid phase outlet is located above the liquid phase outlet, the feed inlet is located between the solid phase outlet and the liquid phase outlet, and a discharge pipe is connected to the solid phase outlet.

[0006] As a preferred embodiment of the rinsing equipment for soil pollution remediation of this utility model, a flow gap is provided between the auger blades and the inner wall of the separation tube.

[0007] As a preferred embodiment of the soil pollution remediation rinsing equipment of this utility model, wherein: an interceptor plate and an overflow plate are fixedly installed in the inner cavity of the sedimentation tank, the interceptor plate and the overflow plate divide the inner cavity of the sedimentation tank into an inlet chamber, an overflow chamber and an outlet chamber, and the inlet chamber, the overflow chamber and the outlet chamber are interconnected.

[0008] As a preferred embodiment of the leaching equipment for soil pollution remediation of this utility model, a sludge removal baffle is rotatably installed on the sedimentation tank, and a water outlet pipe is provided on the side of the sedimentation tank opposite to the sludge removal baffle, and the water outlet pipe is connected to the water outlet chamber.

[0009] As a preferred embodiment of the soil pollution remediation rinsing equipment of this utility model, a shower box is fixedly installed on the separation pipe at the inlet, and a spraying mechanism is built into the shower box. A sealing component is provided at the inlet, and the sealing component includes a sealing arc plate slidably installed at the inlet. A driving half-ring fixedly connected to the sealing arc plate is slidably installed on the outside of the separation pipe near the sealing arc plate.

[0010] As a preferred embodiment of the leaching equipment for soil pollution remediation of this utility model, the separation pipe is equipped with a support ring, and a support rod is fixedly installed on the outer convex surface of the support ring away from the separation pipe. The end of the support rod away from the separation pipe and the bottom of the sedimentation tank are both provided with casters.

[0011] The beneficial effects of the leaching equipment for soil pollution remediation of this utility model are as follows: by setting the separation components, the operation of separating the liquid phase and solid phase of the leaching agent mixed with solid particles is completed. By utilizing the setting of the flow gap, the liquid phase can be separated from the polluted soil under its own gravity. Compared with traditional separation equipment, the problem of solid particles clogging the filter screen is avoided, and the separation efficiency is greatly improved. Attached Figure Description

[0018] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0019] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0020] Reference Figure 1 - Figure 4 This embodiment provides a leaching device for soil pollution remediation, including a sedimentation tank 1 for settling the separated leaching agent, and a separation component 2 for separating the solid and liquid phases in the leaching agent, including an inclined separation pipe 21, which has an inlet 22, a solid phase outlet 23 and a liquid phase outlet 24 connected to the sedimentation tank 1.

[0021] During separation, the eluent mixed with solid particles is first introduced into the separation tube 21 through the feed port 22. After separation by the separation tube 21, the liquid phase enters the sedimentation tank 1 through the liquid phase outlet 24 for sedimentation, and the solid phase is discharged through the solid phase outlet 23, thus completing the separation of the liquid phase and solid phase of the eluent mixed with solid particles.

[0022] The solid phase outlet 23 is located above the liquid phase outlet 24, and the inlet 22 is located between the solid phase outlet 23 and the liquid phase outlet 24. A discharge pipe 25 is connected to the solid phase outlet 23. A rotating rod 26, coaxial with the separation tube 21, is rotatably mounted inside the separation tube 21. An auger blade 28 is fixedly sleeved on the outside of the rotating rod 26, and the end of the rotating rod 26 away from the sedimentation tank 1 passes through the separation tube 21 and is fitted with a separation motor 27 fixedly connected to the separation tube 21. A flow gap 29 is provided between the auger blade 28 and the inner wall of the separation tube 21.

[0023] like Figure 3As shown, a rotating rod 26 is rotatably installed inside the separation tube 21. An auger blade 28 is mounted on the rotating rod 26, and the auger blade 28 does not contact the inner wall of the separation tube 21. A flow gap 29 is provided between the auger blade 28 and the inner wall of the separation tube 21. Therefore, when the eluent mixed with solid particles enters the separation tube 21 through the feed inlet 22, the separation motor 27 is activated to drive the rotating rod 26 to rotate. The rotation of the rotating rod 26 drives the auger blade 28 to rotate, thereby guiding the solids entering the inner cavity of the separation tube 21 to the solid phase outlet 23. Furthermore, from... Figure 1 As can be seen, the separation tube 21 is inclined, and a flow gap 29 is provided between the auger blade 28 and the inner wall of the separation tube 21. Therefore, when the solid particles are pushed upward by the auger blade 28, the liquid in the eluent will flow along the flow gap 29 towards the liquid phase outlet 24 under the influence of its own gravity, until it flows into the sedimentation tank 1, while the solid phase will enter the solid phase outlet 23 and then flow out from the outlet pipe 25. This setting, mainly due to the ability to freely adjust the appearance of the liquid phase, avoids the filter screen being blocked by solid particles compared with traditional separation equipment, and greatly improves the separation efficiency.

[0024] An interceptor plate 11 and an overflow plate 12 are fixedly installed in the inner cavity of the sedimentation tank 1. The interceptor plate 11 and the overflow plate 12 divide the inner cavity of the sedimentation tank 1 into an inlet chamber 13, an overflow chamber 14 and an outlet chamber 15, and the inlet chamber 13, the overflow chamber 14 and the outlet chamber 15 are interconnected.

[0025] from Figure 3 As can be seen, the lower part of the inlet chamber 13 is connected to the overflow chamber 14, and the upper part of the overflow chamber 14 is connected to the outlet chamber 15. When the rinsing agent enters the sedimentation tank 1, it first enters the inlet chamber 13. The interceptor plate 11 set between the inlet chamber 13 and the overflow chamber 14 can prevent the rinsing agent from directly entering the overflow chamber 14. It must enter the overflow chamber 14 through the flow channel at the bottom of the inlet chamber 13 and the overflow chamber 14. The rinsing agent in the overflow chamber 14 will stand in the overflow chamber 14 until the liquid level of the rinsing agent in the overflow chamber 14 exceeds the overflow plate 12, and only then will some liquid enter the outlet chamber 15. In step 5, since the rinsing agent entering the sedimentation tank 1 contains not only liquid but also a small amount of small solid particles, the settling of this part of the rinsing agent in the overflow chamber 14 allows the small solid particles to accumulate at the bottom of the overflow chamber 14 under the influence of their own gravity. Therefore, the rinsing agent flowing into the outlet chamber 15 basically does not contain solid particles, further improving the separation effect of the solid and liquid phases in the rinsing agent. The setting of the interceptor plate 11 can prevent the rinsing agent that has just entered the sedimentation tank 1 and has not been settling from flowing directly to the upper layer of the overflow chamber 14 and entering the outlet chamber 15, thereby ensuring the effect of settling and sedimentation of the rinsing agent.

[0026] A sludge removal baffle 16 is rotatably installed on the sedimentation tank 1, and a water outlet pipe 17 is provided on the side of the sedimentation tank 1 opposite to the sludge removal baffle 16, and the water outlet pipe 17 is connected to the water outlet chamber 15.

[0027] After a period of use, the mud removal baffle 16 can be opened to clean the solid sediment at the bottom of the inlet chamber 13 and the overflow chamber 14, ensuring the normal use of the subsequent sedimentation process. In addition, during use, the rinsing agent in the outlet chamber 15 can be discharged through the outlet pipe 17 for easy subsequent treatment.

[0028] A shower box 3 is fixedly installed on the separation pipe 21 at the feed inlet 22, and a spraying mechanism is built into the shower box 3. A sealing component 4 is provided at the feed inlet 22. The sealing component 4 includes a sealing arc plate 41 that is slidably installed at the feed inlet 22. A drive half ring 42 that is fixedly connected to the sealing arc plate 41 is slidably installed on the outside of the separation pipe 21 and near the sealing arc plate 41.

[0029] The contaminated soil is first placed in the shower box 3, and then the built-in spraying mechanism in the shower box 3 sprays the contaminated soil with a washing agent to remove the pollutants in the contaminated soil. After a period of reaction, the semi-ring 42 is driven to push the sealing arc plate 41 to move, thereby releasing the seal at the feed inlet 22 and facilitating the soil to enter the separation tube 21 for solid-liquid separation.

[0030] A support ring 5 is installed on the separation tube 21. A support rod 6 is fixedly installed on the outer convex surface of the support ring 5 away from the separation tube 21. A caster wheel is provided at the end of the support rod 6 away from the separation tube 21 and at the bottom of the sedimentation tank 1. 7

[0032] The support ring 5 and the support rod 6 can support the separation pipe 21, preventing the entire equipment from becoming unbalanced and tipping over during operation, which would affect the normal operation. In addition, the end of the support rod 6 away from the separation pipe 21 and the bottom of the sedimentation tank 1 are equipped with casters. The casters facilitate the transportation of the equipment. In conventional settings, shower equipment is usually fixed in one place and cannot be moved as needed, which has a large limitation in use and a limited range of applications.

[0033] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
