Detailed Description
The present application is described in further detail below with reference to the accompanying drawings.
The embodiment of the application discloses a reclaimed water recycling system of an open width washing machine. Referring to fig. 1 and 2, the reclaimed water recycling system of the open-width washing machine comprises a recycling tank 1 and an annular filter screen 3, wherein the recycling tank 1 is a cylinder, a water inlet 11 and a water outlet 12 are respectively formed in the center of the top and the edge of the bottom of the recycling tank 1, and the water inlet 11 is used for receiving wastewater.

Referring to fig. 2 and 3, the number of the annular filter screens 3 may be multiple, in this embodiment, two annular filter screens 3 are adopted, the two annular filter screens 3 are coaxially distributed, the two annular filter screens 3 divide the inner space of the recycling tank 1 into a water inlet cavity 13, an interlayer cavity 14 and a water outlet cavity 15, the innermost is the water inlet cavity 13, the middle is the interlayer cavity 14, and the outermost is the water outlet cavity 15. The mesh number of each annular filter screen 3 increases progressively along the rivers direction, and the mesh number that leans on the annular filter screen 3 of water inlet 11 of inboard is less promptly for filter the great impurity of granule in the waste water, and the mesh number that leans on the annular filter screen 3 of delivery port 12 of outside is great, is arranged in filtering the less impurity of granule in the waste water, with this avoid the great impurity of granule to block up the annular filter screen 3 that the mesh number is high fast and make this annular filter screen 3 lose efficacy fast, with this maintenance frequency that reduces annular filter screen 3.
All be equipped with hydraulic pressure detection piece 2 in intake antrum 13, intermediate layer chamber 14 and the play water cavity 15, hydraulic pressure detection piece 2 mountable is on the top inner wall of retrieval and utilization case 1 to this reduces the hydraulic pressure interference phenomenon that the water depth change leads to, promotes the referential of hydraulic pressure value, and hydraulic pressure detection piece 2 just has great numerical value when three cavity is full of liquid simultaneously, with the water level state of this detectable three cavity.

The control module is used for triggering the judgment module when the hydraulic pressure of the water inlet 11 is higher than a first set value and the hydraulic pressure of the water outlet 12 is reduced to a second set value; the first set value is higher than the second set value, when the hydraulic pressure of the water inlet 11 is higher than the first set value, the flow of the waste water is normal, and the recycling tank 1 can be filled with the waste water so that the waste water passes through the two annular filter screens 3. When the hydraulic pressure of the water outlet 12 is reduced to a second set value, the hydraulic pressure of the water outlet 12 is attenuated, and the flow of the wastewater is reduced at the time, which indicates that the filtering efficiency of the annular filter screen 3 is too low.
After the judging module is triggered, whether the annular filter screens 3 are blocked or not is judged according to the hydraulic pressure difference values corresponding to the annular filter screens 3 and the set threshold values;
if the hydraulic pressure difference exceeds the set threshold value, the annular filter screen 3 is indicated to be blocked, and a prompt signal is output at the moment.
Specifically, the filtering efficiency is different due to the different mesh sizes of the two annular filtering nets 3, and the smaller the mesh size of the annular filtering net 3 is, the smaller the flow rate is. Therefore, even if two annular filter screens 3 are new, the actual hydraulic attenuations on the two sides of the two annular filter screens are different, so that two set thresholds need to be set, each annular filter screen 3 corresponds to one set threshold, and the smaller the mesh number is, the smaller the set threshold is, so as to accurately judge whether the annular filter screens 3 are blocked. When the hydraulic pressure difference exceeds a set threshold value, the filtering efficiency attenuation of the annular filter screen 3 is serious, and the annular filter screen needs to be cleaned or replaced, so that a prompt signal is output, and the prompt signal can be represented as an audible and visual alarm, a popup window displayed on a human-computer interaction interface and the like.
