Technical Field

[0001] This utility model relates to the field of filtration equipment, and more particularly to a filtration device, a groundwater pollutant treatment device, and an assessment device. Background Technology

[0002] The rational use of groundwater is a common way to support agricultural planting and industrial production activities. However, groundwater is susceptible to pollution from production and daily life.

[0003] To purify collected contaminated groundwater, existing technology proposes a composite groundwater treatment device, comprising a mixing tank, a flotation tank, and a subsequent treatment unit, which are sequentially connected. The groundwater to be purified first enters the mixing tank, where agitation is initiated, and reagents are added and mixed with the groundwater. This allows the reagents to react with the corresponding pollutants, generating solid impurities. The settled groundwater is then introduced into the flotation tank, where microbubbles and upward water flow are generated, causing the solid impurities to float to the surface. The groundwater, after solid impurities have been removed, flows into the subsequent treatment tank for further purification.

[0004] The aforementioned device lacks an optimized design for filtering and removing solid impurities, and the cumbersome process of removing solid impurities during repeated use is extremely inconvenient.

[0005] Therefore, it is necessary to provide a new filtration device to solve the above-mentioned technical problems. Utility Model Content

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0040] Please refer to the following: Figures 1 to 4 One embodiment of the present invention provides a filtration device, comprising:

[0041] A mixing tank 1 is provided with a cover plate 4 and a stirring component 2 at its top and bottom, respectively. An aeration device 3 is provided inside the mixing tank 1 and is arranged around the stirring component 2. Two feeding hoppers 7 and a feeding pipe 8 are both provided on the cover plate 1.

[0042] A settling trough structure 6 is arranged around the top of the mixing tank 1. The mixing tank 1 has multiple through holes 62, each of which is connected to the settling trough structure 6.

[0043] The filter mechanism 10 includes a housing 101, a filter screen 102, and a control pipe 103. The control pipe 103 connects the housing 101 to the bottom end of the settling tank structure 61. The filter screen 102 is installed inside the housing 101. A valve 11 is provided on the control pipe 103.

[0044] The scraping device 5 includes a bracket 51, a motor 52 and a scraper 53. The motor 52 is mounted on the cover plate 4 through the bracket 51. The drive shaft of the motor 52 passes through the cover plate 4 and is connected to the scraper 53. The scraper 53 is correspondingly arranged with the through hole 62.

[0045] The discharge pipe is located at the bottom of the mixing box 1 and is connected to the bottom of the box body 10 through a guide pipe.

[0046] In this embodiment, control valves can be installed on both the control pipe and the discharge pipe.

[0047] In the initial state, the control pipe is closed, and the liquid to be treated is transported to the interior of the mixing tank 1 through the injection pipe 8. The reagent is added into the mixing tank 1 through the two feeding hoppers 7.

[0048] The stirring device 2 is activated to mix the agent and the liquid to be treated to generate solid impurities. The microbubbles generated by the aeration device 3 can adsorb the solid impurities generated by the reaction and make them float to the surface in time.

[0049] Then, the motor 52 is started to drive the scraper 53 to transport the floating solid impurities and liquid through the through hole 62 into the interior of the settling tank structure 61.

[0050] At this time, the control tube can be opened, and solid impurities and liquid enter the tank 101 through the settling tank structure 61, and the solid impurities are removed by the filter screen 102.

[0051] After cleaning, the discharge pipe is opened, and the liquid filtered to remove solid impurities is output through the discharge pipe. This ultimately achieves automated filtration to remove solid impurities, making the operation convenient and efficient.

[0052] In this embodiment, the two feeding hoppers 7 can respectively feed flocculant and coagulant aid, and the liquid to be treated can be groundwater.

[0053] The mixing element 2 enables the flocculant and coagulant aid to fully mix and react with the groundwater, while the microbubbles generated by the aeration device 3 can promptly adsorb the flocculents produced by the reaction and cause them to float and separate. The synergistic effect can achieve solid-liquid separation more efficiently, remove impurities from the groundwater, and enhance the overall treatment effect.

[0054] Please refer to it again. Figure 1 The bracket 51 is located between the two feeding hoppers 7 to optimize the space at the top of the cover plate.

[0055] Please refer to it again. Figure 3 The number of scraper blades 53 is multiple, and each scraper blade 53 is arranged in a one-to-one correspondence with the through hole 62. This improves the scraping efficiency of the scraper blades.

[0056] Please refer to the following: Figure 5 , Figure 6 and Figure 7 The filtration device further includes a rinsing assembly 20; the rinsing assembly 20 includes an annular conveying pipe 201, multiple rinsing heads 202, an L-shaped conveying pipe 203, and a plug-in connector 204. The annular conveying pipe 201 is installed inside the settling tank structure 61 via a snap-fit ​​bracket 21. The multiple rinsing heads 202 are respectively opened at the bottom of the annular conveying pipe 201. One end of the L-shaped conveying pipe 203 passes through the cover plate 4 and communicates with the annular conveying pipe 201. The plug-in connector 204 is connected to the other end of the L-shaped conveying pipe 203.

[0057] When it is necessary to flush out the residual solid impurities inside the settling tank structure 61, first connect the plug-in connector 204 to the external liquid conveying equipment.

[0058] The liquid is transported through the L-shaped conveying pipe 203 to the inside of the annular conveying pipe 201. After the liquid is transported to the inside of the annular conveying pipe 201, it is sprayed onto the sides and bottom of the inner wall of the settling tank structure 61 through multiple flushing heads 202 on the surface of the annular conveying pipe 201.

[0059] The housing 101 is equipped with a disassembly door 12 to facilitate subsequent cleaning and maintenance of the interior of the housing 101.

[0060] This utility model also provides a groundwater pollutant treatment device.

[0061] The groundwater pollutant treatment device includes a conveying device 14, a secondary filter box 13, an oxidation box 15, and a filtration device, wherein the filtration device, the conveying device 14, the secondary filter box 13, and the oxidation box 15 are connected in sequence.

[0062] In this embodiment, the secondary filter box is filled with filter elements, which are used to remove heavy metal impurities from groundwater.

[0063] The filter element is a heavy metal adsorption packing material, which may include zeolite, bio-manganese oxide and vermiculite.

[0064] The oxidation chamber 15 can be equipped with electrodes and ultraviolet lamps. The electrodes include a cathode plate and an anode plate. Ionization can be achieved through the action of the cathode plate and the anode plate, which accelerates the degradation of organic matter in the water. The ultraviolet lamps can sterilize and disinfect the groundwater, thereby achieving a three-stage purification process for the groundwater and ensuring the purification effect of the groundwater.

[0065] Finally, the purified groundwater can be discharged through the right-side conduit of oxidation tank 15.

[0066] This invention also provides a device for assessing groundwater pollutants.

[0067] The equipment for assessing groundwater pollutants includes a groundwater pollutant treatment device and a detector, with the detector located on top of the mixing tank 1.

[0068] The detector can be a suspended solids concentration detector.

[0069] Mixing tank 1 generates microbubbles through aeration device 3, causing solid impurities to float to the surface. After flotation treatment, the content of suspended solids in the water flow is detected by a suspended solids concentration detector, which can intuitively understand the effect of solid-liquid separation. If the suspended solids concentration is too high, it indicates that the flotation effect is not good. It is necessary to adjust the aeration rate of the aeration device, check the use of flocculant, or maintain the equipment to ensure that subsequent treatment links are not affected and improve the overall treatment efficiency.

[0070] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
