Specific embodiment

The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.

As shown in Figures 1 to 5, a kind of drum filter of belt scraping plate, including rectangular shell 1, the side of the shell 1 There are two water inlet 2 and a sewage draining exit 4, water outlet is set to side opposite with water inlet 2 on shell 1 for setting, in shell 1 Horizontal positioned rotary drum 5 is installed, one layer is fixed on the outside of the rotary drum 5 strainer, water inlet 2 and sewage draining exit 4 with rotary drum 5 Inside connection, wherein rotary drum 5 open at one end simultaneously sticks on shell the side for being provided with water inlet 2, the opening of the rotary drum 5 Sealing strip is provided on the inside of edge and shell 1, rotary drum 5 is connect far from one end of water inlet 2 with rotary motion mechanism, the revolution Driving mechanism is for driving rotary drum 5 to rotate about the axis, specifically, being arranged on the end face of the one end of the rotary drum 5 far from water inlet 2 There is ring gear, which engages with gear, and the shaft connection of gear and motor, motor driven gear rotation is to drive ring gear to turn Dynamic, ring gear drives 5 unitary rotation of rotary drum again,

Wherein, 1 bottom of shell is fixed with multiple turning rolls, and idler wheel 10 and turning rolls are pivotally connected, the idler wheel 10 Axis it is parallel with the axis of the rotary drum 5, the idler wheel 10 is for being supported rotary drum 5.Preferably, in order to make idler wheel 10 Preferably rotary drum 5 is supported, in preferred embodiment, 5 both ends of rotary drum are circumferentially fixed with a chow ring respectively The flange 51 of shape, 1 bottom of shell are fixed with four rolling 10, and card slot 101 is circumferentially offered on the wheel face of the idler wheel 10, described The flange 51 at 5 both ends of rotary drum is fastened in the card slot 101.

Wherein, agitating paddle 8 is fixedly installed with inside told rotary drum 5, agitating paddle 8 includes loom, and one end of the loom is fixed On the side wall of shell 1, the other end is deep into rotary drum 5, and the blade perpendicular to loom is fixed on the side of loom, when turn Drum 5, which carries out rotation, to be made, and internal sewage is driven to rotate to form vortex, and since agitating paddle 8 is fixedly installed, it is opposite It is rotated in rotary drum 5, so as to be stirred to the sewage in rotary drum 5, the granule foreign in sewage can be better dispersed, from And it can be improved filter efficiency.

The scraper plate 9 of 5 lateral wall of rotary drum can be connected to by being rotatably assorted on the inside of the shell 1, specifically, scraper plate 9 Side and the inner sidewall of shell 1 are hinged, and the other end is movable end, and 9 bottom of scraper plate is connected with pushing mechanism, passes through pushing mechanism Scraper plate 9 is pushed, so that the vertical end of scraper plate 9 carries out vertical rotating, in this application, which can be oil cylinder, The piston rod of oil cylinder pushes the activity end motion of scraper plate 9, and when the rotary drum 5 rotation, the rotary drum 5 connects with the scraper plate 9 Contacting surface is from top to bottom moved relative to the scraper plate 9, in order to make it easy to understand, by taking rotary drum 5 is rotated counterclockwise as an example, scraper plate 9 It is set on left shell 1, rotary drum 5 and the contact surface of scraper plate 9 can then be moved down relative to scraper plate 9 at this time, similarly, work as rotary drum 5 when being rotated clockwise, and scraper plate 9 is then set to the right side of shell 1.

Sewage enters rotary drum 5 from water inlet 2, and rotary motion mechanism driving rotary drum 5 starts turning, greater than of strainer diameter Grain object can be intercepted in strainer, these particle wastes can be then discharged by sewage draining exit 4.

And since partial particulate waste is identical as aperture of filter screen, particle waste can be partially engaged in the hole of strainer, When needing to clear up these particle wastes, first the water in shell 1 can be drained, scraper plate 9 is pushed by pushing mechanism, makes scraper plate 9 abut with rotary drum 5, then rotate rotary drum 5, and by moving under upper, scraper plate 9 can will be fastened on for the contact surface of rotary drum 5 and scraper plate 9 Particulate matter hanging fascia or cutting in strainer, these can then fall on 9 upper surface of scraper plate by the particulate matter that scraper plate 9 is retained down, to scraping Plate 9 is cleared up, to clear up particulate matter.

Preferably, in order to avoid scraper plate 9 causes to damage in scraper to strainer, the application using plastic plate as scraper plate 9, It further, can be using Teflon plate as scraper plate 9.

The application further includes flusher 6, and the flusher 6 includes the water pipe 61 for being fixed on 1 top of shell, the water Pipe 61 is connected to nozzle group, and the nozzle group is connect towards the strainer, the water pipe 61 with recoil water pump 62, anti-by opening Jet water pump 62 makes liquid discharge to clean strainer by nozzle group again by water pipe 61.

Wherein, the nozzle group is arranged along 61 length direction of water pipe, the sprinkling direction of nozzle group and towards the strainer, institute Stating nozzle group includes atomizer 63 and fluid nozzle 64, and atomizer 63 and fluid nozzle 64 pass through pipeline and water pipe 61 respectively Connection, wherein be equipped with atomizing piece 631 inside the atomizer 63, which is ultrasonic atomization piece 631, works as liquid Body can be dispersed as liquid grain when passing through atomizing piece 631.

It with the increase for using the time, can be blocked by impurity on strainer, strainer can be carried out by flusher 6 at this time It rinses, so that the impurity on strainer be rinsed, during the rinsing process, rotary motion mechanism can drive 5 turns of rotary drum Dynamic to be convenient for cleaning, the application can be dispersed as little particle liquid when liquid passes through atomizer 63 due to including atomizer 63 Mist, liquid can discharge a large amount of anion in atomization process, electrostatic can occur with the grease stain on strainer and react, make itself It is adsorbed on the outside of grease stain, so that grease stain be wrapped up, the grease stain wrapped up then can more easily be fallen by fluid scouring.

In addition, the application is also provided between atomizer 63 and water pipe 61 in order to preferably clear up strainer Atomization valve 632 is provided with fluid valve 641 between fluid nozzle 64 and water pipe 61, can by atomization valve 632 and fluid valve 641 With spray head used in the control of selectivity, to play the effect for preferably cleaning strainer, for example, can be closed when greasy dirt is less Atomization valve 632 is closed to increase the water velocity sprayed, fluid valve 641 can be first closed when greasy dirt is more, to increase atomization quantity, Preferably, atomization valve 632 and fluid valve 641 can use solenoid valve.

In addition, further including for detecting the liquid level induction system of liquid level difference inside and outside the filter screen (figure in the application In be not shown), liquid level induction system is fixed on the outside of shell 1, when the dirt adhered on filter screen is more, inside and outside can shape At liquid level difference, when liquid level induction system detects that liquid level difference is greater than some setting value, liquid level induction system sends letter Number controller is given, controller starting recoil water pump 62, fluid nozzle 64 is rinsed strainer, thus by impurity from sewage draining exit 4 It goes out.

The application is hinged with mobilizable lid 7 at the top of the shell 1, and the lid 7 is for opening and closing the shell 1.It should be understood that the application controls each mechanism by controller, specifically, controller is PLC controller.

Embodiment described above is only preferred embodiments for fully illustrating the utility model, the utility model Protection scope it is without being limited thereto.Those skilled in the art made equivalent substitute or change on the basis of the utility model It changes, both is within the protection scope of the present invention.The protection scope of the utility model is subject to claims.
