A backwashing square tube is arranged on the right side of the filter square tube and extends upward and downward. A working hole is formed between the backwashing square tube and the filter square tube. A main shaft is arranged in the working hole and extends forward and backward along its axis. Four filter plates extend radially around the main shaft. The interval angle between adjacent filter plates is equal. One end of the main shaft is connected to a power assembly for rotating control.

[0005] The utility model further provides that the upper end of the backwashing square tube has a backwashing inlet, and the lower end has a backwashing outlet. A water distributor is arranged near the backwashing inlet in the backwashing square tube.

[0006] The utility model further provides that the cross section of the filter square tube is the same as that of the backwashing square tube, and their sizes are equal.

[0007] The utility model further provides that the power assembly is arranged outside the filter square tube and the backwashing square tube.

[0011] In order to make the technical personnel of the prior art better understand the technical scheme of the utility model, the preferred embodiment of the utility model is described below in conjunction with specific examples, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, and not for the limitation of the utility model patent claim. Based on the examples in the utility model, all other examples obtained by the ordinary technical personnel in the art without creative labor belong to the scope of protection of the utility model.

[0012] The utility model is further illustrated below in conjunction with the drawings and preferred examples.

[0013] Example 1

[0014] Referring to Figure 1 As shown in the drawing, the grinding sewage filtering device of the embodiment includes the filtering square tube 1 extending up and down, the upper end of the filtering square tube 1 has the sewage inlet 2, and the lower end has the sewage outlet 3, the right side of the filtering square tube 1 is provided with the backwashing square tube 4 attached thereto and extending up and down, the working hole 5 is opened between the backwashing square tube 4 and the filtering square tube 1, further including the main shaft 6 extending into the working hole and having the axis extending front and back, the main shaft 6 is provided with four filtering plates 7 extending along the radial direction, the interval angle between the adjacent two filtering plates 7 is equal, and the one end of the main shaft 6 is drivingly connected with the power assembly (not shown) for rotating, and the power assembly includes the motor and the speed reducer.

[0015] Further, the upper end of the backwashing square tube 4 has the backwashing inlet 8, and the lower end has the backwashing outlet 9, and the backwashing square tube 8 is provided with the water distributor 10 close to the backwashing inlet.

[0016] Further, the cross section of the filtering square tube 1 is the same as the shape of the cross section of the backwashing square tube 4, and the size is equal.

[0017] Further, the power assembly is arranged outside the filtering square tube 1 and the backwashing square tube 4.

[0018] In the embodiment, the sewage is discharged from the sewage inlet 2 and discharged from the sewage outlet 3, during which, the filtration is carried out by the filtering plate 7, and part of the particulate impurities is filtered out, at the same time of the filtration by the filtering plate 7, the power assembly carries the main shaft 6 and all the filtering plates 7 thereon to rotate at low speed, the filtering plate 7 rotating out of the filtering square tube 1 and rotating into the backwashing square tube 4 is backwashed by the water distributor 10 above to restore the filtration performance.

[0019] When the backwash square tube 4 is not equipped with a water distributor 10, an external water source can be used to connect to the backwash inlet 8 to backwash the filter plate 7 that has been transferred into the backwash square tube 4.

[0020] Among them, by evenly distributing four filter plates 7 around the outer circumference of the main shaft 6, when the filter plate 7 extending into the filter square tube 1 is horizontal, the two adjacent filter plates 7 are vertical, which closes the working hole 5 and the spacing blocks part of the sewage from flowing sideways.

[0021] The grinding wastewater filtration device involved in this utility model can backwash the filter plates that have been rotated out of the filter square tube and into the backwash square tube by rotating and switching the filter plates, thereby restoring their filtration performance, ensuring that each filter plate has a continuous and good filtration performance, excellent filtration effect, complete overall function, and strong practicality.
