Quick-assembly detachable downpipe water purification device and method

Abstract

The invention discloses a quick-assembly detachable downpipe water purification device and method. The quick-assembly detachable downpipe water purification device comprises a rough filtration device, a check valve, a water flow spiral speed increaser and a filter box, the rough filtration device is used for filtering large-particle impurities such as leaves and disintegrating slag in rainwater flow, and the large-particle impurities pass through the check valve after being preliminarily filtered; the check valve receives water coming from the front end and injects the water into the water flow spiral speed increaser; the water flow spiral speed increaser accelerates the flow speed of water flow and increases the amount of water passing through the downpipe in unit time by utilizing spiral protrusions on the surface, and the accelerated rainwater enters the filter box and enters the water storage cellar through the downpipe below the filter box; the filtering box utilizes different filtering materials in the filtering box to purify rainwater in a grading manner; the water flow spiral speed increasers and the filter boxes form filter combinations, and the three filter combinations are arranged in the equipment from top to bottom. The device has the advantages of being convenient to disassemble and assemble, outstanding in drainage and filtering efficiency, low in maintenance cost and wide in application range.

Description

technical field [0001] The invention relates to the technical field of water purification devices, in particular to a quick-installed and detachable downpipe water purification device and method. Background technique [0002] Water resources are generally scarce in northern my country, and the promotion of roof rainwater collection technology can effectively supplement different needs such as green irrigation, road washing, and daily washing. However, because there are many foreign objects such as branches, leaves, dust, and debris on the roof of the building, the existing rainwater collection methods are still unable to quickly distinguish the sewage in the early stage from the cleaner rainwater in the later stage, which is prone to the following disadvantages: [0003] 1. The traditional downpipe collection method leads to the failure to discharge the sewage in the early stage, and the sewage and clean water enter the water storage equipment together, prolonging the water ...

AI Technical Summary

Problems solved by technology

However, because there are many foreign objects such as branches, leaves, dust, and debris on the roof of the building, the existing rainwater collection methods are still unable to quickly distinguish the sewage in the early stage from the cleaner rainwater in the later stage, which is prone to the following disadvantages:

[0003] 1. The traditional downpipe collection method leads to the inability to discharge the sewage in time in the early stage, and the sewage and purified water enter the water storage equipment together, prolonging the water purification cycle

[0004] 2. In the existing downpipe patent, the rainwater relies on gravity to infiltrate naturally, the water speed is slow and the filtration efficiency is low, and the excess clean rainwater cannot be discharged in time

For example, Zheng Zhenyi's (China, 2017) "A Downpipe Filter" (Application No.: CN201720649865.X) did not consider timely discharge measures for excess rainwater

[0005] 3. The cost of filter materials in existing downpipe patents is relatively high

For example, "A Downpipe Filter" (Application No.: CN201910030167.5) by Gong Xibo et al. (China, 2019) uses high-cost materials such as filter cotton, which is not conducive to large-scale promotion

[0006] 4. Most of the existing downpipe patents are applicable to newly-built houses. It is difficult to renovate the downpipes of existing houses, and it is not conducive to quick disassembly and maintenance
