Description

Technical Field

[0001] This invention relates to the field of soil and groundwater remediation technology, and in particular to a soil and groundwater remediation device. Background Technology

[0002] As people's living standards continue to improve, and with the acceleration of urbanization and the implementation of industrial restructuring policies in my country, the severity of contaminated sites is becoming increasingly prominent. Among these issues, soil pollution and its impact on groundwater are serious problems caused by industrial pollution sources, excessive application of inorganic fertilizers, and pesticide residue pollution.

[0003] The treatment of soil and groundwater pollution includes the application of remediation agents. Due to the differences in the application environment of soil and groundwater, different application devices are generally required to be installed in specific locations. Furthermore, the operation methods of different application devices also vary, resulting in complicated installation and operation procedures. Summary of the Invention

[0004] This invention discloses a soil and groundwater remediation device, which aims to solve the technical problem that the operation methods of different delivery devices are somewhat different, resulting in complicated installation and operation procedures.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A soil and groundwater remediation device includes an injection mechanism. The injection mechanism comprises an outer tube containing an adjusting mechanism. Multiple first perforations are formed through the outer wall of the outer tube near its bottom end. A bearing seat is located on the bottom outer wall of the outer tube, and an inner tube is movably connected within the bearing seat and situated inside the outer tube. A spiral conveyor plate is fixedly connected to the outer wall of the inner tube, and multiple second perforations are formed through the outer wall of the inner tube near its bottom end. First filter screens are fixedly connected within the multiple second perforations. A partition is fixedly connected to the inner wall of the inner tube, and a storage bin is separated within the inner tube by the partition. A feeding device is tightly connected to the inner wall of the top of the partition. The inner tube has a second gear fixedly connected to its outer wall at the top, and the outer wall of the second gear is movably meshed with a first gear. A stepper motor is fixedly connected to the outer wall at the top of the first gear. A guide housing is connected to the inner wall at the top of the outer tube, and connecting pipes are tightly connected to the inner walls of the opposite sides of the guide housing. A diversion mechanism is connected to one end of each connecting pipe. A support base is fixedly connected to the outer wall at the top of the guide housing, and the inner tube is movably connected to and passes through the support base. A bearing bracket is fixedly connected to one outer wall of the support base, and the first gear is movably connected to the bearing bracket. The stepper motor is fixed to the top of the bearing bracket.

[0007] Equipped with an injection mechanism, the solid remediation agent is first placed in the storage silo through a supply hose. In soil environments, the lower end of the remediation device is buried underground, and tap water is continuously injected into the storage silo through the supply hose. After the tap water mixes with some of the solid remediation agent, it is discharged into the outer pipe through the first filter screen. A stepper motor drives the first gear to rotate, which in turn drives the inner pipe to rotate through the second gear. Under the action of the spiral conveyor blades, the water containing the remediation agent is squeezed from bottom to top and discharged through the diversion mechanism. This allows for simultaneous soil irrigation and uniform application of the remediation agent. In groundwater environments, the lower end of the remediation device is placed in the groundwater environment. Groundwater enters the outer pipe through the first perforation, comes into contact with the remediation agent through the first filter screen, and is squeezed into the diversion mechanism by the moving spiral conveyor blades and flows out. This allows for full utilization of groundwater and uniform mixing of groundwater and remediation agent through the device, completing the application of groundwater remediation agent. With this structure, the remediation device can be used for both soil and groundwater remediation agent application, effectively improving its utilization range.

[0008] In a preferred embodiment, the adjusting mechanism includes an annular baffle, a slot is provided through the outer tube, and the annular baffle is movably connected to the slot. Multiple third perforations are provided through the outer wall of the annular baffle near its bottom, and multiple third filters are fixedly connected to the multiple third perforations. An arc-shaped sliding groove is provided through the inner wall of the top of the guide housing. Multiple first slides are fixedly connected to the outer wall of the top of the annular baffle, and the first slides are movably connected to the arc-shaped sliding groove. Second slides are fixedly connected to the outer walls of the tops of the multiple first slides respectively. The bottom ends of the multiple second slides are attached to the outer wall of the top of the guide housing, and support rings are simultaneously fixedly connected to the outer walls of the tops of the multiple second slides. Multiple handles are provided at equal density on the outer walls of the tops of the support rings.

[0009] The system is equipped with an adjustment mechanism. In this mechanism, multiple handles drive the entire annular baffle to rotate within the trough, changing the position of multiple third filters so that they are located within the trough or coincide with the positions of multiple first perforations. This allows the outer tube to switch between sealed and open states, thus adapting to both soil and groundwater environments.

[0010] In a preferred embodiment, the diversion mechanism includes diversion pipes, which are respectively and tightly fixed to opposite ends of two connecting pipes. Multiple diversion ports are evenly spaced on the inner wall of the bottom end of each diversion pipe. An outer cover is fixedly connected to the outer wall of the bottom end of each diversion pipe, and linear sealing slide rails are simultaneously fixedly connected to the inner walls of opposite sides of the outer cover. A sealing slider is movably engaged within the linear sealing slide rail, and a support plate is movably connected to the linear sealing slide rail via the sealing slider. Multiple cutting discs are evenly spaced on the outer wall of the bottom end of the support plate, and the direction of the multiple cutting discs is consistent with the direction of the linear sealing slide rail. A second filter screen is fixedly connected to the inner wall of the outer cover, and the second filter screen is located at the top of the support plate.

[0011] By incorporating a diversion mechanism, when the remediation agent is discharged into the diversion mechanism through the connecting pipe, it is discharged into the soil or groundwater through multiple diversion ports. The outer cover and second filter screen cover the multiple diversion ports to prevent debris in the soil or groundwater from clogging them. Simultaneously, with the arrangement of multiple cutting blades, when the remediation device is placed underground, during the discharge process through the multiple diversion ports, the support plate moves laterally along the linear sealed slide rail, and the multiple baffles loosen the surrounding soil, thereby facilitating the rapid absorption of the remediation agent. In a groundwater environment, the support plate drives the baffles to reciprocate, which can play a certain role in stirring the groundwater around the remediation agent and promote the rapid mixing of the remediation agent.

[0012] As described above, a soil and groundwater remediation device includes an injection mechanism. The injection mechanism includes an outer tube, inside which is an adjusting mechanism. Multiple first perforations are penetrating the outer wall of the outer tube near its bottom end. A bearing seat is located on the bottom outer wall of the outer tube, within which an inner tube is movably connected. The inner tube is located inside the outer tube. A spiral conveying plate is fixedly connected to the outer wall of the inner tube. Multiple second perforations are penetrating the outer wall of the inner tube near its bottom end, and multiple first perforations are fixedly connected to the multiple second perforations. The filter screen has a baffle plate fixedly connected to the inner wall of the inner tube, and a storage bin is separated from the inner tube by the baffle plate. A feeding hose is tightly connected to the inner wall of the top of the baffle plate. A second gear is fixedly connected to the outer wall of the top of the inner tube, and a first gear is movably meshed with the outer wall of the second gear. A stepper motor is fixedly connected to the outer wall of the top of the first gear. A guide shell is connected to the inner wall of the top of the outer tube, and connecting pipes are tightly connected to the inner walls of the opposite sides of the guide shell. A diversion mechanism is connected to one end of each connecting pipe. The soil and groundwater remediation device provided by this invention has the technical effect of being able to apply remediation agents to soil and groundwater separately, effectively improving its application range.

Multiple first perforations 115 are provided through the outer wall of the outer tube 108 near its bottom end. A bearing seat 107 is provided on the outer wall of the bottom end of the outer tube 108. An inner tube 102 is movably connected inside the bearing seat 107 and is located inside the outer tube 108. A spiral conveying plate 116 is fixedly connected to the outer wall of the inner tube 102. Multiple second perforations are provided through the outer wall of the inner tube 102 near its bottom end, and multiple second perforations are fixedly connected to... The system includes a first filter screen 106, a partition 104 fixedly connected to the inner wall of the inner tube 102, and a storage bin 105 separated from the inner tube 102 by the partition 104.

In soil conditions, the lower end of the remediation device is buried underground, and tap water is continuously poured into the storage silo 105 through the supply hose 101. After the tap water mixes with some of the solid remediation agent, it is discharged into the outer pipe 108 through the first filter screen 106. The stepper motor 113 drives the first gear 112 to rotate, which in turn drives the inner pipe 102 to rotate through the second gear 114. Under the action of the spiral conveyor plate 116, the water containing the remediation agent is squeezed from bottom to top and diverted. Mechanism 2 discharges, thereby simultaneously achieving soil irrigation and uniform application of remediation agent. In a groundwater environment, the lower end of the remediation device is placed in the groundwater environment. Groundwater enters the outer pipe 108 through the first perforation 115, comes into contact with the remediation agent through the first filter screen 106, and is squeezed into the diversion mechanism 2 by the moving spiral conveyor plate 116 and flows out. This allows for full utilization of groundwater and uniform mixing of groundwater and remediation agent through the device, completing the application of groundwater remediation agent. Under this structure, the remediation device can be used for the application of remediation agents for soil and groundwater respectively, effectively improving its application range.

The top outer walls of the support rings 307 are provided with a plurality of handles 308 at equal density. In the adjustment mechanism 3, the entire annular baffle 304 is rotated along the slot 302 by the plurality of handles 308, changing the position of the plurality of third filters 303 so that they are located in the slot 302 or coincide with the position of the plurality of first perforations 115. This allows the sealing and opening states of the outer tube 108 to be switched, thereby adapting to soil environment and groundwater environment respectively.

[0026] Reference Figure 4 In a preferred embodiment, the diversion mechanism 2 includes a diversion pipe 201, and the diversion pipe 201 is tightly fixed to one end of each of the two connecting pipes 110 facing each other. The bottom inner wall of each diversion pipe 201 is provided with a plurality of diversion ports 202 at equal density.

A sealing slider 206 is movably engaged inside the linear sealing slide rail 205, and a support plate 207 is movably connected to the linear sealing slide rail 205 through the sealing slider 206.

[0028] Reference Figure 4In a preferred embodiment, a plurality of cutting discs 208 are fixedly connected at equal density to the bottom outer wall of the support plate 207, and the arrangement direction of the plurality of cutting discs 208 is consistent with the arrangement direction of the linear sealing slide rail 205.

Simultaneously, with the multiple cutting plates 208 in place, when the remediation device is placed underground, during the drainage process through the multiple diversion ports 202, the support plate 207 moves laterally along the linear sealing slide rail 205, loosening the surrounding soil through the multiple partitions 208, thus facilitating the rapid absorption of the remediation agent. In a groundwater environment, the support plate 207 drives the partitions 208 in reciprocating motion, which can stir the groundwater surrounding the remediation agent, promoting rapid mixing of the remediation agent.

[0029] Working principle: First, the solid remediation agent is placed in the storage silo 105 through the supply hose 101. In soil environments, the lower end of the remediation device is buried underground, and tap water is continuously poured into the storage silo 105 through the supply hose 101. After the tap water mixes with some of the solid remediation agent, it is discharged into the outer pipe 108 through the first filter screen 106. The stepper motor 113 drives the first gear 112 to rotate, which in turn drives the inner pipe 102 to rotate through the second gear 114. Under the action of the spiral conveyor plate 116, the water containing the remediation agent is squeezed from bottom to top and discharged through the diversion mechanism 2. This simultaneously achieves soil irrigation and uniform dispensing of the remediation agent. In groundwater environments, the lower end of the remediation device is placed in the groundwater environment, and groundwater enters the outer pipe through the first perforation 115. Inside the tube 108, the remediation agent comes into contact with the first filter 106 and is squeezed into the diversion mechanism 2 by the moving spiral conveyor 116. This allows for the full utilization of groundwater and the uniform mixing of groundwater and remediation agent through the device, thus completing the application of the groundwater remediation agent. Under this structure, the remediation device can be used for the application of remediation agents for soil and groundwater respectively, effectively improving its application range. In the adjustment mechanism 3, multiple handles 308 drive the entire annular baffle 304 to rotate along the empty groove 302, changing the position of multiple third filters 303 so that they are located in the empty groove 302 or coincide with the position of multiple first perforations 115. This allows switching between the sealed and open states of the outer tube 108, thus adapting to the use in soil and groundwater environments respectively.
