Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil remediation technology, and in particular to a chemical dispensing device for soil remediation. Background Technology
[0002] Currently, the common method for soil pollution remediation is chemical injection, which involves injecting remediation agents into soil layers at different depths using drilling equipment. However, existing equipment has certain shortcomings:
[0003] First, depth detection and layered drug injection are not coordinated: traditional equipment relies on manual measurement of borehole depth and cannot dynamically adjust the injection position in real time, resulting in uneven drug distribution.
[0004] Secondly, the problem of clogging of injection holes is prominent: soil backfilling or loose particles after drilling can easily cause the injection holes to collapse and become blocked, requiring repeated cleaning or even secondary drilling, which greatly reduces the efficiency of the operation.
[0005] Finally, the system has low integration: the injection actuator and the anti-blocking device are mostly separate designs, which have poor coordination and occupy a lot of space, making them unsuitable for operation in confined spaces. Utility Model Content

[0028] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0029] like Figures 1 to 5 As shown, this application provides a chemical dispensing device for soil remediation, comprising: a main body 100 of the chemical dispensing device, including a device support 10, a chemical tank 20, a lifting frame 30, a drilling mechanism 40, and a control panel 70. The chemical tank 20 is located at the top of the device support 10, the lifting frame 30 is located in the middle of the device support 10, the drilling mechanism 40 is installed at the upper end of the lifting frame 30, and the drilling mechanism 40 includes a transmission box 41, a drive motor 42, and a drill rod 46. The top of the drill rod 46 is connected to a driven pulley 44; and a lifting assembly 50, located between the device support 10 and the lifting frame 30, including a mounting... The device support 10 has a lifting cylinder 51 at the top, a distance sensor 52 and a guide sleeve 53 installed at the top of the lifting frame 30, and a guide rod 54 adapted to the guide sleeve 53 is provided in the middle of the device support 10; the agent filling anti-clogging component 60 includes a water pump 61, an electric three-way ball valve 62 and an air pump 68 installed inside the agent tank 20, and a high-pressure hose 63 is connected to the bottom of the electric three-way ball valve 62, and a rotary joint 64 is provided between the high-pressure hose 63 and the driven pulley 44. The drill rod 46 has a channel 65 inside, and a pressure sensor 67 is provided on the inner wall of the channel 65.
[0030] After adopting the above technical solution, since the lifting component 50 is located between the device support 10 and the lifting frame 30, and the agent injection anti-clogging component 60 includes a water pump 61, an electric three-way ball valve 62, and an air pump 68 installed inside the agent tank 20, it is possible to drill holes at different depths and remediate the soil. This can solve the problems of inconsistent depth detection and layered injection: traditional equipment relies on manual measurement of drilling depth and cannot dynamically adjust the injection position in real time, resulting in uneven agent distribution; the problem of injection hole clogging is prominent: after drilling, soil backfilling or loose particles can easily cause the injection hole to collapse and become blocked, requiring repeated cleaning or even secondary drilling, which greatly reduces the efficiency of operation; the system integration is low: the injection execution mechanism and the anti-clogging device are mostly designed separately, with poor coordination and large space occupation, which is not conducive to operation in narrow spaces.
[0031] It should be noted that when drilling and injecting remediation fluid into the soil, firstly, the two sets of lifting cylinders 51 are activated via the control panel 70. The output of the lifting cylinders 51 drives the lifting frame 30 to descend, and simultaneously the drilling mechanism 40 is activated. The output of the drive motor 42 drives the drive pulley 43 to rotate, which in turn drives the belt 45 and the driven pulley 44 to rotate, further driving the drill rod 46 to rotate. As the lifting cylinders 51 drive the lifting frame 30 to descend, the drill rod 46 is driven to perform the drilling operation. At the same time, the air pump 68 is activated, and the output of the air pump 68 is controlled via the control panel 70 to connect with the high-pressure hose 6. 3. The channel 65 is opened, and gas is injected into it. The pressure sensor 67 detects the pressure. If the pressure is insufficient, the air pump 68 is continuously started to prevent the channel 65 from becoming blocked during the drilling process of the drill rod 46. The distance sensor 52 detects the depth of the drill rod 46 during its descent. When the set depth is reached, the drilling mechanism 40 and the air pump 68 are stopped. Then, the electric three-way ball valve 62 is controlled by the control panel 70 to connect the water pump 61 and the high-pressure hose 63. The water pump 61 introduces the repair fluid in the chemical tank 20 into the rotary joint 64 and the channel 65 through the high-pressure hose 63, and finally injects it into the soil.
[0032] In an optional embodiment, a baffle 69 is provided in the middle of the medicine tank 20, and the baffle 69 and the medicine tank 20 are an integral structure, which can block the middle of the medicine tank 20, so that the upper end of the baffle 69 is used to store the repair fluid. A liquid level sensor 21 is installed inside the medicine tank 20 to monitor the liquid level of the repair fluid in real time, according to the attached... Figure 1 and 2 It is known that the top of the medicine tank 20 is equipped with an injection port, and the bottom of the baffle 69 is used to house the water pump 61 and the air pump 68.
[0033] In an optional embodiment, the output end of the drive motor 42 is provided with a drive pulley 43, and a belt 45 is connected to the outside of the drive pulley 43. The belt 45 is adapted to the driven pulley 44, which facilitates the drive pulley 43 to rotate through the output end of the drive motor 42. Under the transmission of the belt 45, the driven pulley 44 and the drill rod 46 are driven to rotate, ensuring that the drill rod 46 can perform drilling operations.
[0034] In one optional embodiment, there are two sets of lifting cylinders 51 arranged symmetrically, and the lifting cylinders 51 are electrically connected to the control panel 70. The control panel 70 is provided with control buttons and a display screen on the outside, and a control circuit board and a battery are provided inside the control panel 70, which facilitates the control of the start and stop of the lifting cylinders 51.
[0035] In an optional implementation, the distance sensor 52 is electrically connected to the control panel 70, and the guide sleeves 53 are equidistantly distributed laterally along one side edge of the lifting frame 30 to detect the descent depth during the descent of the lifting frame 30, ensuring that the drill rod 46 can reach the set depth for subsequent soil remediation.
[0036] In an optional embodiment, both the water pump 61 and the air pump 68 are connected to the electric three-way ball valve 62, and the water pump 61 is connected to the reagent tank 20 through a water pipe, which can transport the stored liquid inside the reagent tank 20 to the high-pressure hose 63 and the channel 65. At the same time, gas can be injected into the channel 65 to ensure that the bottom of the channel 65 is not blocked. After the gas is introduced, a positive pressure environment is formed inside the drill rod 46 to prevent soil particles from entering the borehole.
[0037] In one optional embodiment, the rotary joint 64 is connected to the high-pressure hose 63, and the driven pulley 44 and the drill rod 46 are an integral structure. During the rotation of the driven pulley 44, the middle part of the rotary joint 64 is rotated to ensure that the high-pressure hose 63 is not rotated. A bearing is provided between the drill rod 46 and the lifting frame 30 to ensure that the drill rod 46 can rotate normally and play the role of drilling.
[0038] In an alternative embodiment, the high-pressure hose 63 is connected to the channel 65, and the bottom of the channel 65 is embedded with a ceramic liner 66, and the inner wall of the channel 65 is inlaid with a ceramic liner 66 to reduce mud adhesion.
