Description

Technical Field

[0002] In the process of purifying well water and river water, it is necessary to use advanced and mature water purification technologies for treatment. These technologies involve multiple steps to improve and enhance water quality. Purified water has a wide range of applications, such as daily water, water resources required for factory production, industrial cooling circulating water, and primary water sources required for pure water preparation systems. Whether it is water for drinking or water required for industrial production, it needs to be purified. Quartz sand filters, as a commonly used filtering equipment, are mainly responsible for removing impurities in water, such as silt, colloids, rust, etc., thereby effectively reducing the turbidity of water. Therefore, quartz sand filters play a vital role in the process of water purification.

The entire filtering process of the utility model undergoes three filtrations, which can filter and purify large and small impurities in the water, with a high filtering effect and improved water quality. In addition, the uniform distribution structure can evenly disperse water into the coarse quartz sand filler and the fine quartz sand filler, effectively avoiding water accumulation, increasing the filtering burden of quartz sand, and further improving the filtering effect.

[0040] Reference Figure 1 , Figure 4 The circulation component also includes a connecting pipe 42, which is used to connect the water injection pipe 43 and the water inlet pipe 41. The upper surface of the upper flange 71 is fixedly connected to the lower surface of the connecting pipe 42, and the left surface of the connecting pipe 42 is fixedly connected to the right surface of the filter barrel 1.

The lower surface of the filter barrel 1 passes through and is fixedly connected with the water outlet pipe 44. The filtered water will flow out from the water outlet pipe 44 and flow to the next process.

[0041] Working principle: When the device is used, water is first injected into the water injection pipe 43, the water will flow through the connecting pipe 42 and be injected into the filter barrel 1 from the water inlet pipe 41, and the water entering the filter barrel 1 will pass through the coarse sand layer, fine sand layer, activated carbon layer and filter in turn. The water can be filtered in multiple stages to ensure the cleanliness of the outflowing water. The filtered water will flow from the outlet pipe 44 to the next process.

[0042] After the device has been used for a period of time, scale is likely to remain on the coarse sand layer, fine sand layer, activated carbon layer and filter, which will affect the filtering effect. At this time, it is necessary to replace the coarse sand layer, fine sand layer, activated carbon layer and the activated carbon, coarse sand and fine sand inside the filter.

[0043] During replacement, first unscrew the bolts connecting the mounting block 51 and the clamping block 52, and unscrew the bolts connecting the upper flange 71 and the lower flange 72, then press the positioning block 76 to squeeze the inclined surface of the limit block 73, so that the limit block 73 releases the limit on the L-shaped block 75, and then remove the pipeline.

After the activated carbon, coarse sand and fine sand are replaced, align the T-block 54 with the T-slot 502 to place the coarse sand layer, fine sand layer, activated carbon layer and filter in sequence. After the placement is completed, the barrel cover 3 is plugged into the filter barrel 1. After the plugging is completed, the mounting block 51 and the clamping block 52 will be aligned, and then the bolts are tightened to complete the installation of the barrel cover 3.

[0044] Then align the upper flange 71 and the lower flange 72 and insert the L-shaped block 75 into the slot 701. During the insertion, the L-shaped block 75 will squeeze the inclined surface of the limiting block 73, and the limiting block 73 will move to the right to release the obstruction of the L-shaped block 75. When the insertion is completed, the limiting block 73 will not be squeezed, and the reaction force of the limiting spring 74 will push the limiting block 73 to move to the left and engage with the L-shaped block 75, limit the L-shaped block 75, and then tighten the bolts to complete the connection between the upper flange 71 and the lower flange 72, and complete the installation of the pipeline.
