In the figure:

1. the sewage treatment system comprises a sewage treatment box, 2 parts of a water inlet pipe, 3 parts of a water outlet pipe, 4 parts of a filter plate, 41 parts of filter holes, 5 parts of a sewage sliding channel, 6 parts of a sewage discharge pipe, 42 parts of an anti-blocking hole and 7 parts of a sewage collection bin.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to the attached drawings 1-3, the sewage treatment system comprises a sewage treatment tank 1, wherein a water inlet pipe 2 and a water outlet pipe 3 are respectively arranged at two ends of the sewage treatment tank 1, a plurality of filter plates 4 are arranged between the water inlet pipe 2 and the water outlet pipe 3, the filter plates 4 are obliquely arranged, and the upper ends of the filter plates 4 are inclined towards the water inlet pipe 2; it has a plurality of filtration holes 41 to open on the filter 4, and the aperture of the filtration hole 41 of a plurality of filters 4 is reduced gradually by inlet tube 2 on 3 directions of outlet pipe, and the bottom of the case slope of sewage treatment case 1 sets up, and the horizontal position that is close to the one end of outlet pipe 3 is higher than the horizontal position of the other end, and a plurality of filters 4 are equipped with the smooth dirty passageway 5 that supplies the filth to pass through with the bottom of the case of sewage treatment case 1, and the below of inlet tube 2 is equipped with blow off pipe 6.

Anti-blocking holes 42 are further formed in the surface, close to the water outlet pipe 3, of the filter plate 4, the anti-blocking holes 42 are in one-to-one correspondence with the filter holes 41, the anti-blocking holes 42 are communicated with the filter holes 41, and the aperture of the anti-blocking holes 42 is larger than that of the filter holes 41. When the filth can not pass through the filter holes 41 along with the water flow, the anti-blocking holes 42 are provided to facilitate the filth to slide out of the filter holes 41, thereby reducing the situation of blocking the filter holes 41.

Sewage treatment case 1 is close to the one end of inlet tube 2 and is equipped with filth collection storehouse 7, and filth collection storehouse 7 and sewage treatment case 1 intercommunication just locate the below of inlet tube 2, and on filth collection storehouse 7 was located to blow off pipe 6. The filth of below may be stirred when inlet tube 2 drains, stores the filth in filth collecting bin 7 specially, and the filth can avoid being stirred or reduce to stir to avoid influencing the filtration of filter 4.

The bottom of the sewage collecting bin 7 is obliquely arranged, and the bottom of the sewage collecting bin 7 and the bottom of the sewage treatment box 1 form an inclined plate. This setting makes things convenient for when the filth falls to the bottom of the case, through the swash plate landing to filth collection bin 7.

The number of filter plates 4 is three. The filtration hole 41 is big then filter fast, and the filtration hole 41 is little then filter slowly, sets up three filter 4, and two preceding filters 4 can filter most filths, and when the third filter 4 filters, only a bit filths in the sewage, the influence that receives during the filtration will be few, and filtration efficiency will accelerate.

The filter 4 is first board, second board and third board by inlet tube 2 in proper order towards 3 directions on the outlet pipe, and first board and second board all are equipped with smooth dirty passageway 5 with the bottom of the case of sewage treatment case 1, the lower extreme and the sewage treatment case 1 fixed connection of third board. The filth that is blocked by filter 4 when first board and second board can sink to the bottom of the case, then in the filth collection storehouse 7 of the below of inlet tube 2 is fallen to the landing through sliding dirty passageway 5, and the rethread blow off pipe 6 discharges. After the sewage is filtered by the third plate, the sewage is basically free of dirt, and the lower end of the third plate is connected with the sewage treatment box 1, so that the situation that the dirt in the box body possibly pollutes the water filtered by the third plate is conveniently prevented.

The utility model discloses in, inlet tube 2 exhaust sewage can filter through first board, second board and third board in proper order, because only receive a little filth influence when the third board, and filtration efficiency is high. For filter 4 of perpendicular setting, through setting up the filter 4 of slope, the filth more easily from filtering the landing in the hole 41, reduces the emergence of the jam condition to improve the live time of filter 4. Through setting up anti-blocking hole 42, can further reduce the emergence of the jam condition, improve the live time of filter 4. Through setting up smooth dirty passageway 5, filth between filter 4 can be piled up at filth collection storehouse 7 along smooth dirty passageway 5, then discharges and go, and this setting can reduce the filth and pile up on filter 4 to guarantee the filter effect of filter 4, also can prolong the live time of filter 4. Through setting up blow off pipe 6, can in time clear up the filth of sewage treatment case 1, guarantee the filter effect of filter 4 in the sewage treatment case 1, further improve the live time of filter 4.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
