When the user needs to take out the aggregate frame 6 from the aggregate space 14 through the handle 102, the second cover 9 is driven to slide relative to the aggregate frame 6, so that the second cover 9 covers the two feed inlets 61, and then the aggregate frame 6 is driven to move, thereby reducing the probability of leakage of the collected impurities in the aggregate frame 6 through the feed inlets 61.
Further, referring to fig. 2, a second water through-hole 22 is further formed at the bottom of the first partition plate 2 between the filtering space 13 and the collecting space 14, so that the sewage introduced into the collecting space 14 together with the impurities can be introduced into the bottom of the filtering space 13 through the second water through-hole 22 and finally discharged through the water discharge opening 16.
Further, it is preferable that the case 1 is fixedly provided with a filter screen for filtering foreign matters at the second water through-hole 22, so that the probability that the foreign matters collected in the aggregate space 14 directly enter the filtering space 13 is reduced.
The implementation principle of the low-power hospital sewage treatment device provided by the embodiment of the application is as follows:
the sewage enters the water inlet space 12, flows along the flow channel 121 and then enters the filtering space 13 through the first water through hole 21, and flows through the filtering components 4 to filter out impurities with certain particle size in the sewage and leave the impurities on the filtering components 4, and the filtered sewage is discharged through the water outlet 16 for subsequent sewage treatment;
the filtered impurities on the filtering component 4 move along the slideway 132 towards the direction close to the collecting port 133 under the action of the sewage flow and the rotation of the grid rod 42, and enter the collecting hopper 5 through the collecting port 133; the impurity that gets into in the aggregate bin 5 can get into the inside of the aggregate frame 6 that is arranged in the aggregate space 14 through feed inlet 61 again and collect to realize preventing stifled, clear stifled effect in an automatic mode, and treatment effeciency is high, need not to additionally use power consuming equipment simultaneously, and required power is lower during the use.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
