Description

Technical Field

[0001] The invention relates to the technical field of groundwater pollution remediation, and in particular to an auxiliary device for groundwater pollution remediation. Background Art

[0002] With the rapid development of social industrialization, the harm caused by industrial pollution is becoming more and more serious, especially the discharge of some industrial wastewater, which not only pollutes the soil, but also falls into the ground and comes into contact with groundwater, thus polluting the groundwater.

[0003] At present, extraction technology is adopted for groundwater repair. Specifically, groundwater is first pumped into a pool on the ground by a water pump, and then relevant chemical repair drugs are added into the pool to chemically repair the groundwater, and then the repaired water flow is discharged back into the underground, so as to achieve the effect of groundwater repair. Because some solid particles of rocks or soil are mixed in the groundwater, these particles will affect the mixing of chemical repair agents and groundwater, so they need to be filtered. Although the existing fixed filter structure can achieve a good filtering effect on groundwater, due to the high particle content in the groundwater and the large water flow rate extracted, the filter structure needs to be replaced regularly, which is more troublesome, and the filtration of groundwater is also delayed during the replacement process.

[0051] See also Figure 1-8 , the present invention provides a technical solution:

[0052] An auxiliary device for groundwater pollution remediation, comprising a support base 1;

[0053] A water tank 11 is installed on the support base 1, one side of the water tank 11 is connected to a water inlet pipe 12, and the other side of the water tank 11 is connected to a water outlet pipe;

[0054] A filter assembly 14 is installed on the water tank 11. The filter assembly 14 includes a first transmission roller 1401 rotatably connected to the inside of the water tank 11, a second transmission roller 1404 rotatably connected to the outside of the water tank 11, and an active roller 1405. A filter belt 1402 is sleeved on the first transmission roller 1401, the second transmission roller 1404, and the active roller 1405.

[0055] The first driving roller 1401 divides the filter mesh belt 1402 into a water inlet section 1406 near the water inlet pipe 12 and a water outlet section 1407 near the water outlet pipe.

[0056] The filter belt 1402 divides the water tank 11 into a to-be-filtered area 1408, a primary filter area 1410 and a secondary filter area 1409 which are connected in sequence;

[0057] The support base 1 is also provided with a scraper assembly 16 for acting as the filter mesh belt 1402 and a collection box 13 for receiving excrement discharged from the scraper assembly 16;

[0058] The support base 1 is also provided with a filter driving assembly 15 for driving the active roller 1405 and the scraper assembly 16 to rotate.

[0059] In this embodiment, Figure 1 As shown, the area to be filtered 1408 is the area close to the water inlet pipe 12, and the secondary filtering area 1409 is the area close to the water outlet pipe 21. In order to achieve a better filtering effect, the first transmission roller 1401 should be located in the area close to the bottom of the water tank 11, and the distance between the first transmission roller 1401 and the bottom end of the inner wall of the water tank 11 can just pass the filter belt 1402.

[0060] When in use, the water inlet pipe 12 is connected to a water pump, which can extract groundwater and pump it into the water tank 11 through the water inlet pipe 12. Since the groundwater is mixed with some solid particles of rocks or soil that may affect the repair effect, a filter component 14 is required to filter and pre-treat the aforementioned impurities. Abandoning the traditional fixed filter plate, this embodiment adopts a driveable filter belt 1402, which has two main functions. First, through the setting of the first drive roller 1401, the filter belt 1402 is bent into an inlet section 1406 and an outlet section 1407 that are spaced apart. The inlet section 1406 and the outlet section 1407 can both filter the flowing water in the water tank 11. That is, through the bending setting of the filter belt 1402, the number of filtration times is increased, and the effect of improving the filtration quality is achieved within an effective space; second, the driveable filter belt 1402 can bring the impurities remaining thereon during filtration out of the water tank 11, and return to the water tank 11 again after the scraping action of the scraper assembly 16. In this way, the filter belt 1402 can always maintain a high filtration capacity, which can reduce the frequency of replacing the filter structure, thereby achieving the effect of improving the filtration efficiency.

[0061] The collecting box 13 may be located below the scraper assembly 16. The first transmission roller 1401, the second transmission roller 1404 and the driving roller 1405 are provided to facilitate the transmission of the filter mesh belt 1402 on the one hand, and to increase the filtering surface of the filter mesh belt 1402 in the water tank 11 on the other hand, so as to ensure a better filtering effect.

[0062] A transmission support frame (not shown) for supporting the second transmission roller 1404 and the active roller 1405 may also be provided on the support base 1 .

[0063] Preferably, the scraper assembly 16 comprises a scraper rotating shaft 1602 , and a plurality of evenly distributed filter scraper plates 1604 are arranged on the outer surface of the scraper rotating shaft 1602 .

[0064] In this embodiment, when the scraper rotating shaft 1602 rotates, the filter scraper plate 1604 will continuously scrape off the impurities on the filter mesh belt 1402, or through the collision between the filter scraper plate 1604 and the filter mesh belt 1402, the impurities remaining on the filter mesh belt 1402 will be shaken off into the collection box 13.

[0065] like Figure 3 and Figure 8 As shown, the scraper rotating shaft 1602 can be installed on the collection box 13 through the scraper mounting frame 1501.

[0066] Preferably, the filter drive assembly 15 comprises a filter drive device 1502, a filter transmission driven gear 1403 sleeved on the active roller 1405, and a filter scraper driven gear 1603 sleeved on the scraper rotating shaft 1602, and the filter driving gear 1503 is sleeved on the output shaft of the filter drive device 1502;

[0067] The filter drive assembly 15 further includes a filter toothed belt 17 sleeved on the filter driving gear 1503 , the filter scraper driven gear 1603 and the filter transmission driven gear 1403 .

[0068] In this embodiment, the filter drive device 1502 can use a reduction motor. When the filter drive device 1502 is started, the filter driving gear 1503 can be driven to rotate, and under the transmission action of the filter toothed belt 17, the filter scraper driven gear 1603 and the filter transmission driven gear 1403 can be synchronously driven to rotate, thereby driving the active roller 1405 to rotate to drive the filter mesh belt 1402, and driving the scraper rotating shaft 1602 to rotate to clean the impurities remaining on the filter mesh belt 1402.

[0069] To support the filter drive device 1502, the filter drive assembly 15 further includes a filter support frame 1501 connected to the support base 1, and the filter drive device 1502 is installed on the filter support frame 1501. The collection box 13 can be installed on the water outlet pipe 21 or on the filter support frame 1501.

[0070] Preferably, the transmission direction of the filter belt 1402 is configured as: from the water outlet section 1407 to the water inlet section 1406 .

[0071] In this way, the filter belt 1402 can be prevented from directly carrying the residual impurities from the to-be-filtered area 1408 to the primary filter area 1410 and the secondary filter area 1409 .

[0072] Preferably, it also includes a repair box 3 connected to the water outlet pipe.

[0073] In this embodiment, after the groundwater that has been filtered and pre-treated enters the repair box 3, chemical repair drugs are placed in the repair box 3 for repair.

[0074] Preferably, the repair box 3 is rotatably mounted on the support base 1 via a rotating seat 2;

[0075] A vertical partition 4 is installed in the repair box 3, and the partition 4 divides the repair box 3 into a first space 18 and a second space 19;

Figure 1As shown, the first stirring component 6 receives the driving action of the filter drive component 15. At this time, the first stirring component 6 can rotate in the first space 18 to mix the chemical repair drug and the groundwater. After the repair treatment in the first space 18 is completed, the position of the first space 18 and the second space 19 are exchanged through the repair drive component 8, so that the second space 19 is located in a position connected to the outlet pipe 21. The second stirring component 7 receives the driving action of the filter drive component 15. At this time, the second stirring component 7 can rotate in the second space 19 to mix the chemical repair drug and the groundwater, and the first space 18 can perform the discharge work.

[0082] Preferably, the first stirring assembly 6 comprises a first shaft 601, a plurality of first stirring rods 602 distributed at equal distances are arranged on the outer annular surface of the first shaft 601, and a first repair driven gear 605 is arranged on the top end of the first shaft 601;

[0085] In this embodiment, starting the filter drive device 1502 can drive the repair driving gear 1504 to rotate. Under the action of the repair drive assembly 8, when the first repair driven gear 605 is engaged with the repair driving gear 1504, the first shaft 601 can be driven to rotate, so that the first stirring rod 602 stirs the first space 18; when the second repair driven gear 705 is engaged with the repair driving gear 1504, the second shaft 701 can be driven to rotate, so that the second stirring rod 702 stirs the second space 19.

[0086] In order to facilitate accurate material discharge, preferably, a material discharge assembly 10 is also included;

[0087] The material unloading assembly 10 comprises a connecting frame 1001 mounted on the partition 4 , and two ends of the connecting frame 1001 are respectively connected to a first material box 1002 sleeved on the periphery of the first shaft 601 and a second material box 1003 sleeved on the periphery of the second shaft 701 .

As the first shaft 601 rotates, the chemical repair drug in the first material box 1002 can be orderly transferred to the first dispersion disk 603, and then as the first dispersion disk 603 rotates, the aforementioned chemical repair drug is evenly distributed and sprinkled into the first space 18; the second spiral blade 704 can form a dragon structure on the second shaft 701. As the second shaft 701 rotates, the ski repair drug in the second material box 1003 can be orderly transferred to the second dispersion disk 703, and then as the second dispersion disk 703 rotates, the aforementioned chemical repair drug is evenly distributed and sprinkled into the second space 19.
