The utility model has the advantages that:

the initial rainwater runoff is less, and impurity, mud isopachous content are high, and the rainwater flows into abandoning the room through the inlet tube, abandons the mouth outflow, accomplishes and abandons a class. As the amount of rain increases, impurities in the rain water decrease. When the flow entering the flow discarding chamber through the water inlet pipe is larger than the flow flowing out from the flow discarding port, the water level of rainwater in the flow discarding chamber is gradually increased, the large floating ball floats up to block the lower port of the flow guiding pipe. Along with the rise of the water level in the drainage chamber, the rainwater enters the clear water chamber after being filtered by the filter screen. The water entering the clean water chamber will inevitably flow into the flow guide pipe through the back washing opening. The size of the big floating ball needs to be ensured, and even if the clear water chamber is filled with water, the big floating ball still can be sealed with the lower port of the flow guide pipe. Thus, the filtered clean water flows out from the water outlet and enters the rainwater collecting tank.

And in the later stage, the flow rate of the water flowing into the flow abandoning chamber along with the water inlet pipe is reduced, the flow rate of the flow abandoning port is gradually larger than the flow rate of the water flowing into the flow abandoning chamber, the water amount of the flow abandoning chamber is gradually reduced, the buoyancy force borne by the large floating ball is reduced, the large floating ball moves downwards under the action of the water in the flow guide pipe and the like, and the residual water in the clean water chamber flows into the flow abandoning chamber through the back flushing port and the flow guide pipe to form the flushing effect on the flow abandoning chamber so as to flush impurities, sludge and the like deposited at the bottom of the flow abandoning chamber out of the flow abandoning chamber. The rainwater discarding and filtering device can not only complete the rainwater discarding and filtering function, but also has the unpowered self-cleaning function, and can be used for a long time without manual cleaning.

The small floating ball is subjected to upward buoyancy after the clear water chamber is filled with water, and can increase the upward buoyancy together with the large floating ball, so that the size of the large floating ball can be reduced.

Detailed Description

The unpowered self-cleaning waste-flow filtering device shown in the figures 1 and 2 comprises a rectangular stainless steel shell 1 with a bottom, wherein the upper part and the lower part of the shell are divided into two parts: the upper half part is a filtered rainwater clear water chamber 13, and the lower half part is a drainage chamber 5; the middle is separated by a filter layer, a fixed baffle 17 which can not penetrate water and a separation layer which is composed of a fixed plate 16.

The filter layer comprises an upper stainless steel filter screen 2 and a lower stainless steel filter screen 2, and a water permeable cloth 3 positioned between the two stainless steel filter screens 2.

The small floating ball 12 is fixedly connected with the big floating ball 6 through a connecting rod 15. The connecting rod 15 can move up and down in the guide tube 9. The guide tube 9 is fixed on the square tube 11 and passes through the square tube 11. The square tube 11 is fixedly connected with the center of the back washing port on the fixed plate. Around the periphery of the duct is a draft tube 10. The draft tube 10 is fixed on the upper and lower parts of the fixed plate and communicated with the back washing port. The upper chamber and the lower chamber of the clear water chamber and the flow discarding chamber are communicated through a guide pipe 10, and rainwater in the clear water chamber flushes the flow discarding chamber downwards through the guide pipe when the flow discarding chamber is cleaned, so that the function of automatically cleaning the flow discarding chamber is completed.

The working principle is as follows: the collected rainwater enters the waste flow chamber 5 through the water inlet pipe 8, and the rainwater which is dirty in the initial stage flows out through the waste flow port 4. Because the inlet tube is phi 200mm, abandon the mouth and be phi 50mm or phi 80mm, when the inlet tube flow was greater than abandon the flow of mouth the flow, the rainwater can be full of and abandon the flow chamber and can upwards flow, through upper and lower two-layer stainless steel filter screen 2 and middle cloth 3 that permeates water, deposit, adsorb, filter the rainwater. The treated rainwater enters the clear water chamber 13. Meanwhile, the water in the flow abandoning chamber floats on the large floating ball 6 of the flow abandoning chamber to block the flow guide pipe. Thus, clean rainwater in the clean water chamber flows out through the water outlet 14, and the rainwater discarding and filtering process is completed (the rainwater in the rainwater discarding chamber flows upwards by virtue of the rainwater fall when the water inlet is higher than the water outlet).

In the later stage of rainwater collection, when the rainwater flow in the water inlet pipe 8 becomes small, the large floating ball falls under the action of the self weight of the large floating ball 6 and the self weight of the rainwater in the guide pipe 10, and the rainwater in the clear water chamber 13 directly flows through the guide pipe 10 to wash the waste flow chamber 5, so that the function of automatically washing the waste flow chamber is completed. The whole equipment can realize the functions of flow discarding, filtering and self-cleaning without power.
