Preferably, the cam further comprises a bolt, a threaded hole is formed in the bottom end of the first rotating shaft, the bolt is screwed in the threaded hole, and the bottom end of the bolt is connected to the left side of the top of the cam.

The working principle is as follows: when the device is required to be used for separating sewage from impurities, a user injects the sewage from the water inlet pipe, the sewage flows on the second screen plate from the water inlet pipe and then enters the small frame body, and then enters the large frame body through the filtration of the first screen plate, at the moment, the user adds the coagulant into the large frame body and controls the motor to rotate to drive the first rotating shaft to rotate so as to drive the first bevel gear to rotate, thereby driving the second bevel gear to rotate, driving the blades to rotate, the blades rotate to mix the sewage and the coagulant in the large frame body so as to enable some suspended matters in the sewage to react, when the sewage and the coagulant in the large frame body react and the impurities precipitate, the user controls the motor to stop working, then the user opens the valve to enable the sewage in the large frame body to be discharged from the discharge pipe, and when no sewage is discharged from the discharge pipe, the user closes the valve, then the user extracts the stopper, and the impurity that big framework bottom precipitated flows from the discharge opening, and the back is all emitted to the impurity that big framework bottom precipitated, and the user is with stopper back discharge opening in. So filter sewage through second otter board and first otter board earlier, can separate most impurity, rethread coagulant and sewage reaction, the impurity of production reprecipitates down, then will get rid of the sewage discharge of impurity, emits the impurity of sediment again, can prevent to get rid of the sewage behind the impurity and receive the pollution of impurity once more.

Because the blanking device is also included, the blanking devices are arranged on the large frame body and comprise a pinion, a bearing seat, a third rotating shaft and a bull gear, first lug, the storage frame, second branch, place board and second spring, all be equipped with the pinion in the second pivot, the pinion is inboard in big framework, support left and right sides lower part all is equipped with the bearing frame, all be equipped with the third pivot in the bearing frame, third pivot outer end all is connected with the gear wheel, gear wheel and pinion meshing, gear wheel outside off-centre position all is equipped with first lug, big framework right wall top in left side and the big framework left wall top in right side all are equipped with the storage frame, storage frame bottom bilateral symmetry is opened there is the through-hole, inboard through-hole is passed on gear wheel upper portion, bottom center is equipped with second branch in the storage frame, the articulated board of placing in second branch top, it all is connected with the second spring to place between inboard and the storage frame bottom in bottom of board bottom. So when adding the coagulant, the user can put into the storage frame with the coagulant, when the second pivot rotates, drive the pinion and rotate, and then drive the gear wheel and rotate, thereby drive first lug and rotate, when first lug rotates to and places the board contact, promote and place inboard rebound of board, make the second spring stretched, also make and place board outside rebound, place in the through-hole entering big framework of coagulant on the board, when first lug rotates to leaving and places the board furthest, the second spring resets, drive and place the board and reset, make the left and right sides of placing the board contact with the storage frame inner wall once more, make the coagulant on placing the board can't flow down. Therefore, the coagulant can be added without people, and the coagulant is gradually added, so that the reaction of the coagulant and the sewage can be better promoted, and the suspended matters in the sewage are less.

Because still including slider, slide rail and apron, left small frame body left wall top on left and right side small frame body right wall top all are equipped with the slider, and the sliding connection has the slide rail on the slider, is equipped with the apron on the slide rail, and the apron covers small frame body top. Therefore, when the equipment is not needed to be used, the small frame body is covered, dust can be prevented from entering the small frame body, and when the equipment is used, the cover plate is pulled open.

Because still including the knocking device, big framework bottom is equipped with the knocking device, the knocking device is including the guide pin bushing, the guide arm, the second lug, the third spring, baffle and cam, it has the cavity to open in the big framework lower wall, all be equipped with the guide pin bushing in the inboard big framework of cavity, the guide pin bushing endotheca has the guide arm, the guide arm inner all is connected with the baffle, the guide arm top all is equipped with the second lug, be connected with the third spring between the second lug of innermost and the cavity inboard, first pivot bottom is connected with the cam, the cam is between the baffle of the left and right sides. So when taking out the impurity that deposits in the big framework again, the user control motor rotates, it rotates to drive first pivot, and then drive the cam and rotate, when the cam rotates to and the baffle contact, promote the baffle and move to the outside, and then drive the guide arm and move to the outside, thereby drive the second lug and move to the outside, make the third spring stretched, the second lug moves to the outside and strikes the cavity top, strike the impurity of big framework bottom, make the impurity of big framework bottom can not remain in big framework bottom, when the cam farthest end changes away from the baffle, the third spring resets, drive guide arm and the reset of last device thereof. So relapse, the big framework bottom is constantly strikeed to the second lug, can let the better outflow of impurity of big framework bottom sooner.

Because still including the bolt, first pivot bottom is opened threaded hole, and threaded hole internal rotation has the bolt, and the bolt bottom is connected in cam top left side. Therefore, when the bottom of the large frame body is not required to be knocked, a user can unscrew the cam, and when the bottom of the large frame body is required to be knocked, the cam can be screwed back.

(3) Advantageous effects

The invention achieves the effects of thorough separation and convenient use, firstly filters sewage through the second screen plate and the first screen plate, can separate most impurities, then reacts with the sewage through the coagulant, generates the impurities and precipitates, then discharges the sewage with the impurities removed, discharges the precipitated impurities, can prevent the sewage with the impurities removed from being polluted by the impurities again, gradually adds the coagulant, can better promote the reaction of the coagulant and the sewage, ensures that suspended matters in the sewage are less remained, and can enable the impurities at the bottom of the large frame body to flow out more quickly and better through the continuous knocking of the second lug at the bottom of the large frame body.
