Description

Technical Field

[0001] This utility model relates to the field of soil and groundwater remediation, and in particular to a permeable chemical injection device for soil and groundwater remediation. Background Technology

[0002] Soil and groundwater remediation refers to the process of taking a series of technical, engineering and management measures to restore the environmental quality of soil and groundwater to acceptable standards or restore their ecological functions in response to pollution caused by human activities or natural factors.

[0003] In existing soil and groundwater remediation methods, various injection methods are employed. For shallow soils, injection wells or injection rods are often inserted directly into the soil to precisely inject the chemical solution into the contaminated area. For deep soils and groundwater, horizontal and directional well technologies can be used to lay pipelines along the direction of the contamination plume to achieve uniform penetration of the chemical solution. Pneumatic injection uses high pressure to force the chemical solution into soil pores and aquifers. In in-situ chemical oxidation and other remediation methods, permeable reactive barrier technology can be used to allow the chemical solution to continuously react with the contaminants under the slow-release effect of the barrier material.

[0004] In the process of soil and groundwater remediation, soil particles, impurities, or chemical crystals can easily clog the outlet of the injection equipment. Some interception structures are unable to cope with complex blockage situations. Once a blockage occurs, it will not only interrupt the remediation process, but also require frequent manual cleaning. To address this issue, a permeable chemical injection device for soil and groundwater remediation is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a permeable chemical injection device for soil and groundwater remediation, which aims to solve the problem that the outlet of the injection equipment in the prior art is easily blocked by soil particles, impurities or chemical crystals, causing the remediation to be interrupted.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 , Figure 4The present invention provides an embodiment of a permeable chemical injection device for soil and groundwater remediation, comprising a mobile carrier 1, a cleaning and stirring mechanism 2 and a connection and disassembly mechanism 3 disposed on the outer wall of the mobile carrier 1, the cleaning and stirring mechanism 2 comprising a storage cylinder 211, the bottom of the storage cylinder 211 being fixedly connected to the top of the mobile carrier 1, the storage cylinder 211 being used to store the remediation chemical solution, and a stirring shaft 212 being rotatably connected to the inner wall of the storage cylinder 211, the stirring shaft 212 being rotatable under the drive of a motor 223, driving a stirring rod. 213. The medicine solution is stirred. A stirring rod 213 is fixedly connected to the outer wall of the stirring shaft 212. The stirring rod 213 can rotate under the drive of the stirring shaft 212 to stir and mix the medicine solution inside the storage cylinder 211, so that the repair agent is evenly dispersed and precipitation is avoided. A connecting cylinder 214 is fixedly connected to the bottom end of the stirring shaft 212. The connecting cylinder 214 can transmit the rotation of the stirring shaft 212 to the rotating rod 215. The rotating rod 215 is slidably connected to the inner wall of the connecting cylinder 214. The rotating rod 215 can move within the connecting cylinder 214. Driven synchronously, it provides rotational power for drill bit 313. A support plate 216 is rotatably connected to the outer wall of the rotating rod 215. The support plate 216 can drive drill bit 313 to descend or rise under the push of hydraulic rod 221, realizing the drilling and retraction of drill bit 313 in the soil. A water outlet ring block 217 is fixedly connected to the bottom of the support plate 216. The water outlet ring block 217 is used to transport the liquid in the storage cylinder 211 into the soil and spray it out. An interception net 218 is fixedly connected to the outer wall of the water outlet ring block 217. 18 can prevent soil from entering the outlet and avoid blockage. A cleaning scraper 219 is fixedly connected to the outer wall of the rotating rod 215. The cleaning scraper 219 can clean the soil attached to the interception net 218 when the rotating rod 215 rotates, ensuring that the outlet is unobstructed. A telescopic pipe 220 is fixedly connected to the bottom of the liquid storage cylinder 211. The telescopic pipe 220 can flexibly transport the liquid during the lifting and lowering of the support plate 216 to ensure the continuity of liquid transmission. The bottom end of the telescopic pipe 220 is fixedly connected to the top of the water outlet ring block 217.

[0032] Reference Figures 2-4The cleaning and mixing mechanism 2 also includes a hydraulic rod 221, the bottom of which is fixedly connected to the top of the mobile carrier 1. The bottom end of the inner rod of the hydraulic rod 221 is fixedly connected to the top of the support plate 216. The hydraulic rod 221 can push the support plate 216 to drive the drill bit 313 to descend or rise, precisely controlling the depth of the drill bit 313 in the soil. The cleaning and mixing mechanism 2 also includes a liquid inlet 222, which is located at the top of the liquid storage tank 211. The liquid inlet 222 facilitates the addition of repair solution to the liquid storage tank 211. The cleaning and mixing mechanism 2 also includes a motor 223, the bottom of which is fixedly connected to the top of the liquid storage tank 211. The output end of the motor 223 is fixedly connected to the top of the mixing shaft 212. The motor 223 provides a power source for the mixing shaft 212, ensuring the smooth operation of mixing and drilling. The cleaning and mixing mechanism 2 also includes a push-pull handle 224, the outer wall of which is fixedly connected to the side wall of the mobile carrier 1. The push-pull handle 224 facilitates the movement of the equipment by the staff and transports it to the location that needs repair.

[0033] Reference Figure 1 , Figure 3 , Figure 4 The connection and disassembly mechanism 3 includes a connecting block 311, the top of which is fixedly connected to the bottom of the rotating rod 215. The connecting block 311 is used to connect the rotating rod 215 and the drill bit 313 to ensure power transmission. The connection and disassembly mechanism 3 also includes a screw 312, the inner wall of which is threadedly connected to the outer wall of the screw 312. The screw 312 can be tightened or loosened to fix and replace the drill bit 313. The connection and disassembly mechanism 3 also includes a drill bit 313, which is detachably connected to the connecting block 311 via the screw 312. The drill bit 313 can be replaced according to different soil conditions and remediation needs to improve the applicability of the equipment.

[0034] Working principle: When soil and groundwater remediation is required, the mobile carrier 1 can be moved to the remediation position by pushing and pulling the handle 224. By starting the motor 223, the output end of the motor 223 drives the fixedly connected stirring shaft 212 to rotate, thereby driving the connecting cylinder 214 fixedly connected to the bottom of the stirring shaft 212 to rotate. Since the outer wall of the rotating rod 215 is fixedly connected to a rectangular block, and the inner wall of the connecting cylinder 214 is provided with a corresponding rectangular groove, when the connecting cylinder 214 rotates, it will drive the rotating rod 215 to rotate synchronously, so that the rotating rod 215 drives the connecting block 311 and the drill bit 313 fixedly connected at the bottom to rotate. By starting the hydraulic rod 221, the inner rod of the hydraulic rod 221 pushes the support plate 216 to descend, thereby driving the drill bit 313 to descend through the support plate 216, so that the drill bit 313 drills into the soil, so as to drive the water outlet ring block 217 into the soil.

[0035] While the stirring shaft 212 rotates, the stirring rod 213, which is fixedly connected to the outer wall of the stirring shaft 212, also rotates. The stirring rod 213 can stir and mix the liquid inside the storage cylinder 211 when the drill bit 313 drills into the soil, so that the repair agent is evenly dispersed and avoids sedimentation, so as to facilitate the subsequent injection of the liquid into the soil. The liquid inside the storage cylinder 211 can enter the water outlet ring 217 through the telescopic tube 220, and finally spray out through the water outlet opened on the outer wall of the water outlet ring 217. The intercepting net 218 can prevent soil from clogging the water outlet. While the rotating rod 215 rotates, the cleaning scraper 219, which is fixedly connected to the outer wall of the rotating rod 215, also rotates. The cleaning scraper 219 can clean the soil attached to the intercepting net 218, so as to prevent soil from clogging the water outlet and affecting the injection of the liquid.

[0036] When it is necessary to change to a different size drill bit 313, the screw 312 on the connecting block 311 is removed, so that the connecting block 311 is no longer fixed to the drill bit 313 by the screw 312, so that other sizes of drill bits 313 can be replaced.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
