Description

Technical Field

[0001] This utility model relates to the field of groundwater purification technology, specifically a groundwater scale inhibition and filtration environmental purification device. Background Technology

[0002] Groundwater, as a crucial component of the water resource system, occupies an irreplaceable position in the natural water cycle and in ensuring water supply for human society. From a natural perspective, groundwater is widely distributed in underground spaces, resembling a vast natural reservoir. Its dynamic balance mechanism and stable recharge characteristics make it a reliable water source for many regions. In agricultural production, groundwater, with its relatively stable quality and minimal impact from seasonal climate changes, has become a core source of irrigation water, ensuring stable and high yields of food and cash crops. In rural areas, groundwater is fundamental to meeting the drinking water needs of people and livestock, directly impacting the quality of life and health of rural residents. In remote urban areas, when groundwater becomes the primary water source, it provides indispensable water resources for residents' daily lives. Especially in arid and semi-arid regions where surface water resources are extremely scarce, groundwater becomes a lifeline for local survival and development.

[0003] However, with the rapid development of human society and economy, groundwater faces increasingly severe pollution challenges. On the one hand, surface environmental pollution is constantly intensifying. Industrial wastewater, domestic sewage, and agricultural non-point source pollution carry large amounts of pollutants into underground aquifers through soil infiltration and surface runoff, leading to the deterioration of groundwater quality. On the other hand, in some areas, due to complex geological conditions and slow groundwater circulation, pollutants continuously accumulate, migrate, and transform in the underground environment, further exacerbating the degree of groundwater pollution. Among existing groundwater purification technologies, flocculation sedimentation is a commonly used treatment method. Its principle is to add flocculants to groundwater to cause suspended particles and colloidal substances in the water to coagulate and precipitate, thereby achieving preliminary purification of the water quality. However, in practical applications, this technology has many significant problems.

[0004] Specifically, when flocculants react with impurities in groundwater, they generate a large number of flocs. These flocs have a large specific surface area and strong adsorption capacity, making them prone to accumulating and clogging on the surface and pores of the filter structure during subsequent filtration processes. As the filtration process continues, the degree of clogging in the filter structure intensifies, leading to a significant increase in filtration resistance and a sharp decrease in filtration rate, severely impacting the purification efficiency and treatment capacity of groundwater. Furthermore, clogging of the filter structure increases equipment maintenance costs and operating energy consumption, reduces equipment lifespan, and poses numerous challenges to the stable operation of groundwater purification projects.

[0005] More seriously, in some areas with severe groundwater pollution, long-term exposure to industrial wastewater discharge and mining activities has resulted in groundwater containing large amounts of minerals such as calcium carbonate, as well as heavy metal ions such as lead, mercury, and cadmium. These pollutants not only alter the physicochemical properties of groundwater but also pose serious threats to human health. For example, long-term consumption of groundwater containing excessive calcium carbonate may lead to calcium salt deposition in the body, causing organ stones such as kidney stones and gallstones. Furthermore, the accumulation of heavy metal ions in the body can interfere with normal physiological metabolic functions, leading to heavy metal poisoning and causing irreversible damage to the nervous, digestive, and immune systems.

[0006] Therefore, strengthening the protection, development, and utilization management of groundwater, and ensuring the sustainable use of groundwater resources, has become an important task in the current construction of ecological civilization. Developing a highly efficient and reliable groundwater scale inhibition and filtration environmental purification device is of significant practical importance and application value for solving the problems existing in current groundwater purification technologies, improving groundwater purification efficiency, and ensuring the safety of residents' drinking water. Based on this, a groundwater scale inhibition and filtration environmental purification device is proposed. Utility Model Content

The output end of the scraping motor is connected to the hollow transmission shaft through the gear set. The hollow transmission shaft is fixedly connected to multiple scraping strips through a transmission seat.

[0012] Both the transmission base and the hollow transmission shaft are rotatably connected to the isolation cover, the isolation cover is fixedly connected to the flocculation separation cage, the bottom ends of the plurality of guide tubes pass through the transmission base and are connected to the hollow transmission shaft, and the surface of the guide tubes is provided with guide holes.

[0013] A stirring motor is installed between the sampling box and the flocculant box. The stirring motor is fixedly connected to the flocculation tank. The output end of the stirring motor passes through the flocculation tank and is fixedly equipped with a stirrer. The stirrer is located on the inner side of the middle of the isolation cover. A qualified water outlet is fixedly installed at the output end of the flocculation tank. The interior of the flocculation tank is connected to the qualified water outlet.

[0014] The sterilization tank and the flocculation tank are connected internally by a sampling box. The flocculant tank is filled with flocculant, and the inner wall at the upper end of the sterilization tank is equipped with a sterilization lamp.

[0015] A water pump and a booster pump are fixedly installed on one side of the sterilization tank, below the storage tank. Each of the water pump and the booster pump has a water intake pipe at one end. The water pump is fixedly installed at the bottom of one of the water intake pipes. The input end of the water pump and the output end of the water pump are connected to the sedimentation tank through one of the water intake pipes.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses a sedimentation tank for initial sedimentation treatment. Then, the sediment remaining at the bottom of the sedimentation tank is filtered by a sediment filter press to further separate water and sand. The clean water is filtered through a filter screen and stored inside a storage tank. The clean water is disinfected and sterilized in a sterilization tank. Then, the clean water in the sterilization tank is guided to the inside of the flocculation tank through a sampling box. The stirring motor drives the stirrer to rotate inside the flocculation separation cage, which can effectively improve the further purification of the clean water by the flocculation separation cage. By periodically activating the cleaning mechanism, the blockage of the flocs generated by flocculation can be effectively avoided.

[0019] 2. This utility model uses a scraping motor to drive a hollow transmission shaft to rotate via a gear set. The hollow transmission shaft then drives multiple scraping strips to rotate inside the isolation cover via a transmission seat. During the rotation, the scraping strips scrape the inner wall of the pressure reducing guide plate, effectively preventing the flocs formed after the water flocculates from clogging the pressure reducing guide plate, maintaining the purification effect of the flocculation separation cage, and extending the service life of the flocculation separation cage. The flocs can be extracted through the guide pipe and discharged centrally through the hollow transmission shaft, thereby reducing the amount of water wasted while ensuring the cleanliness of the inside of the flocculation separation cage.
