Description

Technical Field

[0001] This utility model relates to the field of groundwater technology, and in particular to an in-situ groundwater treatment device. Background Technology

[0002] Groundwater in-situ remediation devices are mainly used for on-site treatment of polluted areas. By implementing remediation technology directly at the pollution source, the transfer of contaminated media is avoided. They have advantages such as low cost and low disturbance. Groundwater needs to be extracted before treatment.

[0003] However, during the process of extracting groundwater, the equipment often encounters the problem that the groundwater contains solid particles such as stones and sand. The presence of these solid particles not only easily wears down the equipment, but also accelerates the wear and damage of equipment components. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an in-situ groundwater treatment device.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0023] Reference Figures 1-3 A groundwater in-situ treatment device includes a base frame 8, and a pumping power assembly is provided on the upper surface of the base frame 8. The pumping power assembly includes a water pump 1, which is fixed to the upper surface of the base frame 8 by bolts. The pumping end of the water pump 1 is connected and fixed to the housing 2.

[0024] The upper surface of the base frame 8 is fixed with a housing 2 by bolts. The upper surface of the base frame 8 is fixed with a fixing frame 5 by bolts. A water guide shell 4 is fixed with bolts on one side of the fixing frame 5. The water pump 1 is started, so that the groundwater enters the interior of the water guide shell 4 through the liquid inlet pipe 15. The top of the water guide shell 4 is connected and fixed with a connecting pipe 3, and the connecting pipe 3 is connected and fixed with the top of the housing 2. The interior of the housing 2 is equipped with a stirring assembly and an intermittent shielding assembly. The stirring assembly includes a connecting shaft 12, which is rotatably connected to the top of the housing 2. Multiple stirring blades 9 are fixed to the outside of the connecting shaft 12 by bolts. A motor is fixed to the top outer wall of the housing 2 by bolts, and one end of the motor output shaft passes through the housing 2 and is fixed to the connecting shaft 12. The rotation of the motor causes the connecting shaft 12 to drive the stirring blades 9 to rotate, so that the extracted groundwater reacts more fully with the reducing agent, and the organic pollutants in the groundwater are dechlorinated and degraded.

[0025] It should be noted that the intermittent shielding assembly includes multiple connecting rods 11, which are fixed to the outside of the connecting shaft 12 by bolts. A retaining ring 10 is fixed between the multiple connecting rods 11 by bolts, and the retaining ring 10 is in contact with the inner wall of the housing 2. The retaining ring 10 can block one end of the liquid outlet of the connecting pipe 3. The retaining ring 10 has multiple slots 13, which can be connected to the connecting pipe 3. At the same time, the rotation of the connecting shaft 12 causes the connecting rods 11 to drive the retaining ring 10 and the slots 13 to rotate. When the slots 13 are connected to the liquid outlet of the connecting pipe 3, the reducing agent enters the housing 2 through the connecting pipe 3. When the retaining ring 10 blocks the liquid outlet of the connecting pipe 3, the feeding stops. This cycle is repeated to allow intermittent feeding into the housing 2.

[0026] In particular, the interior of the water guide shell 4 is equipped with a waste box 19. The top of the waste box 19 is fixed with a filter plate 14 by bolts, and the filter plate 14 is in contact with one end of the liquid inlet of the connecting pipe 3. When groundwater enters the interior of the water guide shell 4, the filter plate 14 filters the impurities in the water, and the filtered water enters the shell 2 through the connecting pipe 3. A cover plate 18 is inserted into the bottom of the water guide shell 4. The cover plate 18 and the water guide shell 4 are detachably connected by a latch 6. The latch 6 facilitates the disassembly and assembly of the cover plate 18 and the water guide shell 4, thereby enabling the cleaning and maintenance of the waste box 19 and the filter plate 14.

[0027] The upper surface of the cover plate 18 is provided with a groove 17. The bottom of the waste box 19 is fixed with a protrusion 16 by bolts, and the protrusion 16 is inserted into the groove 17. The use of the groove 17 and the protrusion 16 makes it easy to position and connect the waste box 19 and the cover plate 18. A feed port is provided on one side of the shell 2. A feed pipe 7 is fixedly connected to the feed port. A reducing agent is added into the feed pipe 7 by external raw material equipment, so that the reducing agent enters the interior of the shell 2. A liquid inlet is provided on one side of the water guide shell 4. A liquid inlet pipe 15 is fixedly connected to the liquid inlet. The liquid inlet pipe 15 is connected to an external pipe, and the connected external pipe extends into the groundwater source.

[0028] Working principle: When it is necessary to treat groundwater, first connect the inlet pipe 15 to the external pipe and extend it into the groundwater source. Start the water pump 1 so that the groundwater enters the water guide shell 4 through the inlet pipe 15 and filters the impurities in the water through the filter plate 14. The filtered water enters the shell 2 through the connecting pipe 3.

[0029] At the same time, a reducing agent is added into the feed pipe 7 through external raw material equipment, so that the reducing agent enters the shell 2. The motor is started, and the motor rotates, causing the connecting shaft 12 to drive the stirring plate 9 to rotate, so that the extracted groundwater reacts more fully with the reducing agent, and the organic pollutants in the groundwater are dechlorinated and degraded.

[0030] At the same time, the rotation of the connecting shaft 12 causes the connecting rod 11 to drive the retaining ring 10 and the slot 13 to rotate. When the slot 13 is connected to the liquid outlet of the connecting pipe 3, the reducing agent enters the shell 2 through the connecting pipe 3. When the retaining ring 10 blocks the liquid outlet of the connecting pipe 3, the feeding stops. This cycle is repeated so that the shell 2 is intermittently fed.

[0031] After the water inside the casing 2 has been initially treated, it is discharged through the outlet of the water pump 1.

[0032] This utility model has been described through the above embodiments. Those skilled in the art will understand that this utility model is not limited to the above embodiments. Many more modifications can be made based on the teachings of this utility model, and all such modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
