Description

Technical Field

[0001] The present invention relates to the technical field of rain and sewage purification equipment, and more specifically, to a fiberglass rainwater purifier. Background Art

[0002] With the gradual enhancement of the overall social environmental protection and conservation awareness, more and more equipment for recycling natural resources has emerged like bamboo shoots after a spring rain. For example, rainwater collection devices for recycling rainwater. Since China is a water-scarce country, especially in inland areas, the water resource problem restricts economic growth and social sustainable development all the time. In recent years, with the gradual expansion of the urban scale, the problem of water resource shortage has become increasingly severe. In order to make better use of natural resources, the demand for rainwater recycling devices is also increasing.

[0003] In the prior art, there is an integrated fiberglass rainwater collection and self-cleaning device with the publication number of CN205475430U. In this integrated fiberglass rainwater collection and self-cleaning device, through the setting of a collector, rainwater from the outside can be easily collected inside the integrated fiberglass rainwater collection and self-cleaning device. The inclined surface design of the collector is beneficial to the flow of rainwater. The first filtration chamber, the second filtration chamber and the storage chamber sequentially arranged inside the integrated fiberglass rainwater collection and self-cleaning device enable the rainwater to be filtered and purified twice through a filter screen and a rainwater purifier, and finally reach the storage chamber for storage for subsequent use. Users only need to open the water outlet valve to obtain clean water. The above device can only achieve simple filtration and purification of rainwater. However, during the purification process, on the one hand, continuous purification treatment of rainwater cannot be achieved, and on the other hand, effective post-treatment of the impurities purified from the rainwater cannot be carried out during rainwater purification. Therefore, the purification function is limited, and the purification method of the above purifier for rainwater is relatively single. Based on this, the present invention provides a fiberglass rainwater purifier to solve the problems raised in the above background art. Summary of the Invention

[0057] The working principle of the present invention is as follows: When in use, the purifier is buried underground, and a placement cavity adapted to the specifications of the purifier is reserved in the ground. The rain inlet pipe 3 is connected to the municipal rainwater supply pipe, and the overflow pipe 7 is connected to the next-stage treatment equipment for rainwater or the relevant drainage pipeline. When the rain inlet pipe 3 feeds rainwater, the rain-driven shaft 30 is driven by the action of the rainwater.

After the outer shaft sleeve 8 is driven, it then drives the spiral filter sheet 10 to lift materials upward and conduct layer-by-layer filtration of the rainwater. The waste residue or floating scum filtered out by the spiral filter sheet 10 finally enters the sewage storage mechanism through the waste guide pipe 13. After the sewage suction shaft pipe 9 rotates, it then drives the purification filter cylinder 6 to rotate. By setting the rotation state of the purification filter cylinder 6, the blockage rate of the filtering structure in the purification filter cylinder 6 is reduced. And after the outer shaft sleeve 8 and the sewage suction shaft pipe 9 are driven, they then drive the pump shaft 37 to work. After the pump shaft 37 works, it then drives the liquid delivery pipe to conduct high-pressure liquid delivery into the inside of the backwashing cavity 36. Through the high-pressure liquid delivery to the backwashing cavity 36, high-pressure water is ejected from the backwashing spray holes 40, and then the backwashing self-purification of the purification filter cylinder 6 is realized. And after the rain-driven shaft 30 is driven, the aeration pipe 4 conducts aeration purification of the rainwater. When the sewage storage mechanism works, the spiral extrusion blade 20 conducts sewage delivery downward and extrudes the accumulated sewage. Through extrusion, the sewage storage capacity of the sewage storage mechanism is increased. When the sewage storage mechanism stores sewage to a specified level, an external hoisting device cooperates with the lifting ring 26 to lift the whole sewage storage mechanism. After lifting, the discharging seat 14 is screwed out, and then the solid sewage accumulated inside the sewage storage cylinder 12 is quickly discharged.
