Description

Technical Field

[0001] This utility model relates to the field of groundwater treatment technology, specifically a groundwater decontamination and filtration device. Background Technology

[0002] Due to surface water pollution and geological structure, groundwater and river water may contain various elements exceeding standards, either individually or simultaneously. These elements include iron, manganese, ammonia nitrogen, fluoride, heavy metals, silt, suspended solids, and so on. Moreover, groundwater taken from the ground will contain a certain amount of silt, algae, and other suspended impurities, making it unsuitable for direct use in production and daily life. Therefore, filtering the raw water is an essential step.

[0003] Because groundwater contains high levels of iron, manganese, ammonia nitrogen, fluoride, heavy metals, silt, and suspended solids, it must be treated before use to meet the required standards. Existing groundwater treatment devices produce a large amount of sediment when purifying groundwater through filter media, requiring effective separation of the sediment from the groundwater. Furthermore, existing filters become clogged during the groundwater filtration process, necessitating the replacement of filter cartridges, resulting in high maintenance costs, impacting the groundwater treatment process, and leading to low reliability. Utility Model Content

[0004] This utility model provides a groundwater decontamination and filtration device, which aims to solve the shortcomings of existing filters mentioned in the background art. When the filters become clogged during the groundwater filtration process, the filter element consumables need to be replaced, resulting in high maintenance costs, affecting the groundwater treatment process, and leading to low reliability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a groundwater decontamination and filtration device, comprising two filter tanks arranged in parallel and a decontamination and filtration assembly connected to the filter tanks via a three-way pipe; an inlet branch pipe is provided at the top of each filter tank, and a water inlet pipe is fixedly connected to the top of the inlet branch pipe; a filter plate is fixedly installed inside each filter tank, and several filter caps arranged in an array are detachably installed on the filter plate; the decontamination and filtration assembly includes a reaction mechanism and a filtration mechanism; the reaction mechanism includes a reaction cylinder and a filter element disposed at the top of the reaction cylinder. The reaction vessel includes an inlet pipe fixedly connected to the tee pipe via a flange, a stirring component located inside the reaction vessel, a dosing port located on one side of the top of the reaction vessel, a drain port located at the tail end of the reaction vessel, and a motor whose output shaft is fixedly connected to the stirring component and fixedly installed on the outer wall of one end of the reaction vessel. The filtration mechanism includes a filter pipe fixedly installed at the tail end of the reaction vessel, a filter element fixedly installed inside the filter pipe, a cleaning component located inside the filter element, a drain port fixedly installed at the end of the filter pipe, and a clean water outlet fixedly installed at the bottom of the filter pipe.

[0006] When in use, first open the one-way solenoid valve on the inlet branch pipe so that the groundwater can flow from the water pipe through the inlet branch pipe into the filter tank. Then the water flows through the sand bed and moves downward in the pores of the sand bed to perform three-dimensional deep filtration, isolating mud, sand and plankton in the upper part of the sand bed. The clean water enters the three-way pipe through the sand bed and the filter cap, thus completing the initial filtration.

[0007] Next, open the three-way solenoid valve on the three-way pipe to allow the groundwater that has been preliminarily filtered in the two filter tanks to enter the reaction cylinder through the inlet pipe. At this time, add the chemical to the reaction cylinder through the dosing port and stir it thoroughly with the stirring component to allow the chemical to react fully with the groundwater. After the reaction is completed, open the drain outlet to discharge the wastewater with sediment into the filter pipe for filtration.

[0008] After the wastewater is filtered by the filter element, the clean water enters the annular cavity between the filter pipe and the filter element through the filter holes and is discharged from the clean water outlet. Meanwhile, the sediment and other impurities remaining in the filter holes are cleaned by the cleaning components and discharged from the drain outlet.

[0009] Preferably, the stirring component includes a stirring shaft with both ends rotatably connected to the inner wall of the reaction cylinder and the filter pipe, and stirring blades fixedly installed on the outer wall of the stirring shaft.

[0010] Preferably, the cleaning component includes a stirring shaft extending to the inside of the filter element, a plurality of mounting plates staggered and fixedly installed on the outer wall of the stirring shaft, and a wire brush fixedly installed on the mounting plates.

[0011] Preferably, the upper surface of the filter plate is covered with a plurality of homogeneous quartz sands of equal particle size to form a sand bed for deep filtration, wherein the particle size of the quartz sand is 0.5-1.5 mm.

[0012] Preferably, the filter plate has a plurality of mounting holes that are adapted to the filter cap.

[0013] Preferably, a one-way solenoid valve is fixedly installed on the water inlet branch pipe, and a three-way solenoid valve is fixedly installed on the three-way pipe.

[0014] This groundwater filtration and treatment device is simple in structure and easy to use. Opening the one-way solenoid valve on the inlet branch pipe allows groundwater to flow from the intake pipe into the filter tank. The water then flows through the sand bed, undergoing three-dimensional deep filtration by moving downwards within the sand bed pores. Silt, plankton, and other contaminants are isolated at the top of the sand bed. The purified water then passes through the sand bed and filter cap into the three-way pipe, completing the initial filtration. Next, opening the three-way solenoid valve on the three-way pipe allows the pre-filtered groundwater from both filter tanks to enter the reaction chamber through the inlet pipe. At this point, chemicals are added to the reaction chamber through the dosing port, and the agitator thoroughly stirs the mixture. The mixture is stirred to ensure the chemicals react fully with the groundwater. After the reaction is complete, the drain outlet is opened to discharge the wastewater containing sediment into the filter pipe for filtration. After the wastewater is filtered by the filter element, the purified water enters the annular cavity between the filter pipe and the filter element through the filter holes and is discharged from the purified water outlet. The sediment and other impurities remaining in the filter holes are cleaned by the cleaning components and discharged from the sewage outlet. This solves the problem that existing filters require replacement of filter elements after clogging during groundwater filtration, resulting in high maintenance costs, affecting the groundwater treatment process, and leading to low reliability.
