Rain water collecting and purifying device

Abstract

The invention discloses a rain water collecting and purifying device which includes a pedestal (1), a supporting device (2), a first filtering apparatus (6), a precipitation apparatus (5), a filter tube (4), a second filtering apparatus (3) and a compression apparatus (7). The supporting device includes a first supporting column, a second supporting column, a first support, a first supporting board, a material collecting box, a second support, a third support and a first vertical rod. The first filtering apparatus (6) includes a first filtering frame (61), a first inclined board (62), a first connection rod (63), a first filter screen (64), a first inclined rod (65), a second vertical rod (66), a holding rod (67), a spring (68) and a transversal rod (69) and a first pipe. The device can filter solid granules away from rain water and then compress and filter the rain water after the impurities are removed. The device is good in effect and is high in efficiency.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a rainwater collection and purification device. Background technique [0002] In today's highly developed industry, people are facing a serious shortage of water resources. Therefore, it is particularly important to make full use of rainwater. After leaving the rainwater mixed with various sundries on the sewer pipes outside the house along the pipes, after filtering The rainwater can be reused, such as for gardens, fields and other places that need water, effectively using natural water resources. Most of the existing roof rainwater purification technologies use initial rainwater abandonment devices, rainwater collection tanks, quartz sand filters, high-pressure water inlet pumps, and backwash water pumps. This kind of rainwater treatment technology has a long process, requires a large area, and consumes a lot of energy. During the idle period, the accumulated ...

Problems solved by technology

This kind of rainwater treatment technology has a long process, requires a large area, and consumes a lot of energy. During the idle period, the accumulated water in the container is easy to stink.

[0003] Chinese patent CN203002095 discloses a high-efficiency energy-saving rainwater purifier, which includes a three-dimensional box, a curved screen, a water inlet, a waste flow valve, a water production valve, a backwash valve, an overflow port, a water collection pipe, and quartz sand. , but due to its low purification efficiency, it is impossible to quickly purify rainwater. At the same time, rainwater cannot be precipitated during the process of collecting rainwater for purification, so that the impurities in it cannot be effectively separated, which will make the purification effect unsatisfactory. , and affect the final rainwater purification effect
