Description

Technical Field

[0001] The utility model relates to the technical field of groundwater treatment equipment, in particular to a pretreatment equipment for heavy metal components in groundwater and soil. Background Art

[0002] After the groundwater resources are exploited and stand still for a period of time, the content of divalent iron ions in the groundwater body will increase. When divalent iron ions encounter air, they will react with oxygen to form trivalent iron ions, causing the water body to turn yellow. Generally, aeration is used to accelerate the precipitation of internal metal elements, so as to realize the purification of groundwater. Since the groundwater contains soil after being exploited, it is necessary to pre-treat the groundwater.

[0003] However, the existing groundwater filtration devices have certain drawbacks. The existing filtration structure cannot be self-cleaned, which easily causes blockage of the filter screen during the groundwater filtration process, thus affecting the groundwater pretreatment effect. Therefore, there is an urgent need for a pretreatment equipment for heavy metal components in groundwater and soil to solve the above problems. Summary of the Utility Model

[0004] To solve the above problems, the utility model provides a pretreatment equipment for heavy metal components in groundwater and soil, and the utility model is realized through the following technical solutions.

[0005] A pretreatment equipment for heavy metal components in groundwater and soil includes a filtration tank and a hoist. One end of the hoist is connected to the filtration tank in a penetrating manner. The top of the filtration tank is fixedly connected with a fixing frame. Three filtration barrels penetrate through the top of the fixing frame. One end of the filtration barrel is fixedly connected with a barrel cover. A water collecting pipe and an air spraying pipe penetrate through the top of the barrel cover. An elevating frame is movably connected inside the filtration tank. The mounting seat penetrating through the top of the elevating frame is movably sleeved on the filtration barrel. A circular brush is fixedly connected to the top of the mounting seat. One end of the hoist is fixedly connected with a hoist motor. The spiral pushing impeller fixedly connected to the output end of the hoist motor rotates inside the hoist, and one end of the spiral pushing impeller extends into the filtration tank. The end of the hoist far away from the filtration tank is connected with a soil discharge pipe in a penetrating manner.

[0006] Furthermore, two servo motors are fixedly connected to the outer surface of the filtration tank. The output shafts of the servo motors are fixedly connected with lead screws. Both ends of the top of the elevating frame are fixedly connected with movable rods. The movable rods movably penetrate through one end of the fixing frame and are fixedly connected with a movable plate. The lead screws penetrate through and are in threaded cooperation with the movable plate.

[0007] Further, a water pump and an air pump are fixedly connected to the outer surface of the filtration tank. The input end of the water pump is fixedly connected with a water suction pipe, and the water suction pipe is connected to the water collecting pipe through a first hose provided. The output end of the water pump is connected with a groundwater output pipeline. The output end of the air pump is fixedly connected with an air inlet pipe, and the air inlet pipe is connected to the air jet pipe through a second hose provided.

[0008] Further, a sewage pipe penetrates through the bottom of the filtration tank, and a sealing cover is arranged at one end of the sewage pipe.

[0009] Further, the elevator is fixedly connected to the bottom of the filtration tank through a hanging bracket, and the elevator is obliquely connected to the filtration tank.

[0010] The beneficial effects of the present utility model are as follows: during the working process of the device, first, groundwater is poured into the filtration tank from the top opening.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0025] As Figures 1-5 shown, the present utility model has the following specific embodiments.

[0026] Embodiment:

[0027] A pretreatment device for the heavy metal components of groundwater and soil, including a filter box 1 and an elevator 2. One end of the elevator 2 is connected to the filter box 1 through penetration. A fixed frame 3 is fixedly connected to the top of the filter box 1. Three filter barrels 31 are connected to the top of the fixed frame 3 through penetration. One end of the filter barrel 31 is fixedly connected to a barrel cover 32. A water collecting pipe 321 and an air injection pipe 322 are connected to the top of the barrel cover 32 through penetration. A lifting frame 4 is movably connected inside the filter box 1. The mounting base 41 penetrating through the top of the lifting frame 4 is movably sleeved on the filter barrel 31. An annular brush 42 is fixedly connected to the top of the mounting base 41. One end of the elevator 2 is fixedly connected to a lifting motor 21. The screw-type pushing impeller 211 fixedly connected to the output end of the lifting motor 21 rotates inside the elevator 2, and one end of the screw-type pushing impeller 211 extends into the filter box 1. The end of the elevator 2 far from the filter box 1 is connected to a soil discharge pipe 22 through penetration.

[0028] By adopting the above technical solution, when using the device, first pour groundwater into the top opening of the filter tank 1. The filter barrel 31 inside the filter tank 1 can filter the groundwater. The filtered groundwater can be pumped out through the water collecting pipe 321. Then, drive the lifting frame 4 to lift and lower in the filter tank 1 by the servo motor 12. The lifting frame 4 can drive the connected annular brush 42 to scrape the outer surface of the filter barrel 31. At the same time, the air injection pipe 322 can inject high-pressure air, and the air can clean the filter holes of the filter barrel 31, so as to facilitate the automatic cleaning of the filter barrel 31, avoid filter blockage. Finally, by turning on the lifting motor 21 to drive the spiral pushing impeller 211 to rotate inside the elevator 2, the spiral pushing impeller 211 can lift and output the soil deposited inside the filter tank 1, which is convenient for filtering groundwater, convenient for self-cleaning, and avoids blockage, thereby improving the pre-treatment filtering effect.

[0029] Specifically, two servo motors 12 are fixedly connected to the outer surface of the filter tank 1. The output shaft of the servo motor 12 is fixedly connected with a lead screw 121. Both ends of the top of the lifting frame 4 are fixedly connected with movable rods 43. The movable rods 43 movably penetrate through one end of the fixed frame 3 and are fixedly connected with a movable plate 431. The lead screw 121 penetrates through and is in threaded cooperation with the movable plate 431.

[0030] By adopting the above technical solution, the dirt on the outer surface of the filter barrel 31 can be scraped off. That is, by turning on the servo motor 12 to drive the lead screw 121 to rotate, the lead screw 121 can drive the movable plate 431 in threaded cooperation to lift and lower. The movable plate 431 drives the connected lifting frame 4 to lift and lower. The lifting frame 4 drives the connected mounting seat 41 to lift and lower. The mounting seat 41 can drive the annular brush 42 to be sleeved on the outer surface of the filter barrel 31 to lift and lower, so that the bristles of the annular brush 42 clean the outer surface of the filter barrel 31.

The air inlet pipe 61 is connected to the air injection pipe 322 through a second hose 611 provided.

[0032] By adopting the above technical solution, the provided water pump 5 can pump water. Since the water suction pipe 51 is connected to the water collecting pipe 321 through the first hose 511, and one end of the water collecting pipe 321 penetrates and extends into the filtering barrel 31, the water filtered into the interior of the filtering barrel 31 can be pumped out. The provided air pump 6 can deliver gas into the air inlet pipe 61. Since the air inlet pipe 61 is connected to the air jet pipe 322 through the second hose 611, and the air jet pipe 322 extends into the filtering barrel 31, the gas entering the filtering barrel 31 can be ejected through the water filtering holes, preventing the water filtering of the filtering barrel 31 from being blocked.

[0033] Specifically, a sewage discharge pipe 11 penetrates and is connected to the bottom of the filtering box 1, and a sealing cover is provided at one end of the sewage discharge pipe 11.

[0034] By adopting the above technical solution, the provided sewage discharge pipe 11 can clean and discharge the dirt remaining inside the filtering box 1, and the sealing cover on the sewage discharge pipe 11 can be aligned for closing or opening.

[0035] Specifically, the hoist 2 is fixedly connected to the bottom of the filtering box 1 through a suspension bracket, and the hoist 2 is obliquely connected to the filtering box 1.

[0036] By adopting the above technical solution, the provided suspension bracket can stably suspend the hoist 2 on the filtering box 1. At the same time, the hoist 2 is obliquely connected to the filtering box 1, facilitating the lifting and output of sludge.
