[0001] This utility model relates to the field of soil remediation technology, and in particular to a soil remediation device with controllable flow rate. Background Technology

[0002] Soil remediation is a technical measure to restore contaminated soil to its normal function. In the soil remediation industry, there are over one hundred existing soil remediation technologies, with more than ten commonly used. These can be broadly categorized into physical, chemical, and biological methods. Since the 1980s, many countries around the world, especially developed countries, have formulated and implemented contaminated soil remediation plans, thus forming a new soil remediation industry.

[0003] Chinese patent discloses a soil remediation device (authorization announcement number CN208303486U). This patented technology features a large stirring amplitude, which can turn the soil in the soil remediation tank over as a whole, resulting in excellent stirring effect, loosening the compacted soil, and achieving excellent remediation effect. The inner wall of the soil remediation tank is provided with a first annular groove, a second annular groove, and multiple strip grooves. The remediation agent delivery pipe is laid in the first annular groove and the strip grooves, and the remediation agent delivery pipe is provided with a round hole, so that the turned soil can fully contact the remediation agent in the remediation agent delivery pipe, resulting in excellent remediation effect.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: When existing soil remediation devices deliver remediation agents internally, it is difficult to control the flow rate of the remediation agent according to specific usage requirements, resulting in different flow rates of the remediation agent during delivery and uneven soil remediation. Utility Model Content

[0005] The technical problem to be solved by this invention is that the existing technology lacks the function of controlling the flow rate of the remediation agent, which leads to uneven soil remediation. Therefore, we propose a soil remediation device with controllable flow rate.

[0006] To achieve the above objectives, this application adopts the following technical solution: a soil remediation device with controllable flow rate, comprising a main body, a cover plate installed on the top of the main body, an air outlet pipe installed on the top of the cover plate, a gas recovery device installed on the top of the air outlet pipe, a remediation agent delivery pipe installed on the left side of the main body, a remediation agent storage box installed on the left side of the remediation agent delivery pipe, a first housing fixedly connected to the surface of the remediation agent storage box, a flow limiting plate slidably connected inside the first housing, a control block fixedly connected to the rear end of the flow limiting plate, a second housing fixedly connected to the left end of the first housing, through grooves opened at both the front and rear ends of the second housing, a movable plate slidably connected inside the through grooves, a fixed rod fixedly connected to the front end of the movable plate, a plurality of fixed holes opened on the surface of the control block, a control rod slidably connected to the top of the second housing, a T-shaped block fixedly connected to the bottom of the control rod penetrating the top of the second housing, and an assist baffle fixedly connected to the top of the control rod.

[0007] Preferably, sliders are fixedly connected to both sides of the T-block, and grooves that cooperate with the sliders are opened on both sides of the interior of the second housing.

[0008] Preferably, a first spring is sleeved on the surface of the control lever, the top of the first spring is fixedly connected to the bottom of the assist baffle, and the bottom of the first spring is fixedly connected to the top of the second housing.

[0009] Preferably, a second spring is fixedly connected to the rear end of the movable plate, and the rear end of the second spring is fixedly connected to the rear end of the inner cavity of the second housing.

[0010] Preferably, a sliding rod is fixedly connected to the rear end of the first housing, and a through hole for cooperating with the sliding rod is provided at the end of the movable plate away from the fixed rod.

[0011] Preferably, the surface of the flow limiting plate is provided with a plurality of flow limiting holes, and the diameter of the flow limiting holes is arranged in descending order.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, pressing the baffle causes the control rod to move the T-block downwards. The T-block then presses against the movable plate, causing the movable plate to disengage the fixed rod from the inner diameter of the fixed hole, thus releasing the control block from its position. By adjusting the position of the control block, the user can make the flow-limiting plate restrict the flow of the repair liquid in the repair agent delivery pipe, preventing uneven flow of the repair liquid and thus preventing uneven soil remediation.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figures 1-4As shown, this utility model provides a technical solution: a soil remediation device with controllable flow rate, including a main body 1, a cover plate 2 installed on the top of the main body 1, an air outlet pipe 3 installed on the top of the cover plate 2, a gas recovery device 4 installed on the top of the air outlet pipe 3, a remediation agent delivery pipe 5 installed on the left side of the main body 1, a remediation agent storage box 6 installed on the left side of the remediation agent delivery pipe 5, a first shell 7 fixedly connected to the surface of the remediation agent storage box 6, a flow limiting plate 8 slidably connected inside the first shell 7, a control block 9 fixedly connected to the rear end of the flow limiting plate 8, a second shell 10 fixedly connected to the left end of the first shell 7, and through grooves 11 opened at both the front and rear ends of the second shell 10, a movable plate 12 slidably connected inside the through grooves 11, and a control block 9 fixedly connected to the front end of the movable plate 12. A fixed rod 13 is fixedly connected to the control block 9. Several fixed holes 14 are opened on the surface of the control block 9. A control rod 15 is slidably connected to the top of the second housing 10. A T-shaped block 16 is fixedly connected to the bottom of the control rod 15 through the top of the second housing 10. An assist baffle 17 is fixedly connected to the top of the control rod 15. By pressing the assist baffle 17, the control rod 15 drives the T-shaped block 16 to move downward. By the T-shaped block 16 squeezing the movable plate 12, the movable plate 12 drives the fixed rod 13 to disengage from the inner diameter of the fixed hole 14, releasing the limitation on the control block 9. The user can adjust the position of the control block 9 so that the flow limiting plate 8 can limit the flow of the repair liquid in the repair agent delivery pipe 5, preventing uneven flow of the repair liquid and causing uneven soil repair.

[0021] Reference Figure 3 As shown in this embodiment: sliders 18 are fixedly connected to both sides of the T-block 16, and grooves 19 that cooperate with the sliders 18 are opened on both sides inside the second housing 10. When the T-block 16 moves, the cooperation between the sliders 18 and the grooves 19 prevents the T-block 16 from tipping over.

[0022] Reference Figure 3 As shown in this embodiment: a first spring 20 is sleeved on the surface of the control rod 15. The top of the first spring 20 is fixedly connected to the bottom of the assist baffle 17, and the bottom of the first spring 20 is fixedly connected to the top of the second housing 10. When the fixing rod 13 is inserted into the movable plate 12 to fix the position of the control block 9, the elastic force generated by the first spring 20 generates an upward force on the assist baffle 17, which limits the position of the T-block 16 and prevents the movable plate 12 from driving the fixing rod 13 out of the inner diameter of the fixing hole 14 when the T-block 16 moves downward.

[0023] Reference Figure 3As shown in this embodiment: the rear end of the movable plate 12 is fixedly connected to a second spring 21, and the rear end of the second spring 21 is fixedly connected to the rear end of the inner cavity of the second housing 10. After the position of the flow limiting plate 8 is adjusted, the assist baffle 17 is released, and the assist baffle 17 is moved upward by the first spring 20, so that the T-block 16 is disengaged from the contact with the movable plate 12. Then, the thrust generated by the second spring 21 causes the movable plate 12 to drive the fixing rod 13 to be inserted into the inner diameter of the fixing hole 14, so that the position of the control block 9 is fixed. After fixing, the elastic force of the second spring 21 limits the position of the movable plate 12, preventing the movable plate 12 from disengaging from the inner diameter of the fixing hole 14 due to vibration or other non-human factors.

[0024] Reference Figure 2 As shown in this embodiment: a sliding rod 22 is fixedly connected to the rear end of the first housing 7, and a through hole 23 is provided at the end of the movable plate 12 away from the fixed rod 13 to cooperate with the sliding rod 22. The sliding connection between the sliding rod 22 and the through hole 23 makes the movable plate 12 more stable when moving, and prevents the movable plate 12 from tilting up at one end when moving.

[0025] Reference Figure 4 As shown in this embodiment: the surface of the flow limiting plate 8 is provided with a plurality of flow limiting holes 24, the diameter of the flow limiting holes 24 being arranged in a decreasing order. By opening a plurality of flow limiting holes 24 with a decreasing diameter, the user can accurately control the flow rate of the repair fluid.

[0026] The working principle of this utility model is as follows: By pressing the assist baffle 17, the user moves the control lever 15 downwards, causing the T-block 16 to move downwards. The T-block 16 then presses against the movable plate 12, causing the movable plate 12 to disengage the fixed rod 13 from the inner diameter of the fixed hole 14, thus releasing the restriction on the control block 9. The user then adjusts the position of the control block 9 to restrict the flow of the repair fluid in the repair agent delivery pipe 5 using the flow-limiting plate 8. Once the flow-limiting plate 8 is properly adjusted, the user releases the assist baffle 17, causing the first spring 20 to move the assist baffle 17 upwards, disengaging the T-block 16 from contact with the movable plate 12. Then, the thrust generated by the second spring 21 causes the movable plate 12 to insert the fixed rod 13 into the inner diameter of the fixed hole 14, thus fixing the position of the control block 9. After fixing, the position of the movable plate 12 is limited by the elastic force of the second spring 21 to prevent the movable plate 12 from being driven by non-human factors such as vibration to disengage the fixing rod 13 from the inner diameter of the fixing hole 14. This prevents uneven flow of the repair fluid and avoids uneven soil repair. At the same time, when the T-block 16 moves, the cooperation of the slider 18 and the chute 19 prevents the T-block 16 from tipping over. The sliding connection between the slide rod 22 and the through hole 23 makes the movable plate 12 more stable during movement and prevents one end of the movable plate 12 from tilting up. By opening several flow-limiting holes 24 with successively decreasing diameters, the user can accurately control the flow rate of the repair fluid.

[0027] 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.
