Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, 2, 5, 6, 7, 8 and 10, the present invention provides a technical solution: the utility model provides a filter equipment, including casing 1 be equipped with play water pipe 2 in casing 1 go out 2 upsides of water pipe and be equipped with water inlet 3 go out the cover on the water pipe 2 and be equipped with and filter drum 4 is provided with a plurality of filter chambers 5 along the circumferencial direction interval on the corresponding position of 3 with the water inlet 5 bottom of filter chamber is equipped with filter screen 61 downside and the corresponding position of filter chamber 5 are equipped with row cinder notch 7 be equipped with in the play water pipe 2 and carry out clear clean mechanism 8 to the mesh of filter screen 6 casing 1 is equipped with outside the first actuating mechanism 9 that can drive and filter drum 4 rotation fixed angle.
When the filtering device is used, sewage enters from the filtering cavity 5 on the upper side of the filtering cylinder 4, enters the water inlet 3 on the upper side of the circular water outlet pipe 2 after passing through the filtering net 6, and is then discharged from the front end of the circular water outlet pipe 2 or flows into the next process, when more garbage is accumulated on the filtering net 6 at the position of the water inlet 3, the first driving mechanism 9 can be controlled to drive the filtering cylinder 4 to rotate for a fixed angle, so that one filtering cavity 5 is switched, the filtering efficiency is effectively improved, when the filtering cavity 5 accumulating more garbage rotates to the slag discharge opening 7, the garbage naturally falls from the slag discharge opening 7 under the action of gravity, and meanwhile, the cleaning mechanism 8 can dredge meshes of the filtering net 6 entering the slag discharge opening 7, so that the filtering net 6 is effectively ensured to be reused.
The cleaning mechanism 8 comprises a cleaning brush 81, the front end of the cleaning brush 81 extends into the rear side of the round water outlet pipe 2, bristles 82 capable of being inserted into meshes of the filter screen 6 are arranged at the position, corresponding to the filter screen 6, of the front end of the cleaning brush 81, the rear end of the cleaning brush 81 extends out of the round water outlet pipe 2, and a second driving mechanism 10 capable of driving the cleaning brush 81 to move up and down when the filter cylinder 4 rotates is arranged between the shell 1 and the cleaning brush 81.
When the filtering cylinder 4 rotates, the cleaning brush 81 is lifted for a certain distance under the action of the second driving mechanism 10, so that the bristles 82 are separated from the meshes of the filtering net at the slag discharge port 7, the rotation of the filtering cylinder 4 is effectively prevented from being blocked, and when the filtering cylinder 4 rotates to a preset angle, the cleaning brush 81 descends again, and at the moment, the bristles 82 are inserted into the meshes of the filtering net switched to the slag discharge port 7, so that the effect of dredging the filtering net 6 is achieved.
A partition wall 11 capable of partitioning the water inlet 3 and the slag discharge port 7 is arranged in the round water outlet pipe 2.
The partition wall 11 divides the water outlet circular tube 2 into two areas, namely a water outlet area and a cleaning mechanism 8 accommodating area, wherein the water outlet area can guide filtered water entering from the water inlet 3 to the front end of the water outlet circular tube 2, the accommodating area is used for installing the cleaning mechanism 8, and the partition wall 11 effectively prevents the filtered water from entering the slag discharge port 7. In another embodiment of the present invention, a dynamic sealing mechanism 12 may be disposed between the rear end surface of the circular water outlet pipe 2 and the cleaning mechanism 8, wherein the dynamic sealing mechanism 12 includes a vertical long groove 121 disposed on the rear end surface of the circular water outlet pipe 2, an interlayer space is disposed on the rear end surface of the circular water outlet pipe 2 outside the vertical long groove 121, a sealing long plate 122 capable of moving up and down is movably disposed in the interlayer space, the rear end of the cleaning brush 81 of the cleaning mechanism 8 is sealingly disposed in the middle of the sealing long plate 122, and when the cleaning brush 81 moves up or down, the sealing long plate 122 correspondingly moves up or down in the interlayer space, so as to always maintain the sealing of the vertical long groove 121, thereby achieving the effect of dynamic sealing. Because the brush hair 82 on the cleaning brush 81 inserts in the mesh of the filter screen 6 of row cinder notch 7 department, at this moment, the filter screen 6 of this department is sealed, the filterable water that gets into from water inlet 3 can only flow to play water pipe 2 front end, in addition, switch the process of filter chamber 5, although brush hair 82 breaks away from the mesh of the filter screen of row cinder notch 7 department for a short time, but filter drum 4 rotation process, water inlet 3 is closed gradually by the junction between two filter chambers 5 earlier, then is opening gradually, so, the water after the filtration only has minimum part to flow through row cinder notch 7, the water that flows out from this time just can carry out the back flush to the filter screen 6 of here.
According to the invention, the rear end of the filtering cylinder 4 is provided with the connecting circular tube 13, the first driving mechanism 9 comprises a transmission gear 91 arranged on the connecting circular tube 13, the outer side of the rear end of the filtering cylinder 4 is provided with a stepping motor 92, a motor shaft of the stepping motor 92 is provided with a driving gear 93, and the driving gear 93 is meshed with the transmission gear 91.
The stepping motor 92 can be connected with a controller, and the rotation angle of the stepping motor 92 can be preset before use according to the number of the filter cavities 5, the ratio of the number of teeth of the driving gear 93 to the number of teeth of the transmission gear 91. When the stepping motor 92 is rotated by a fixed angle or number of turns, exactly one filter chamber 5 is switched. For example, when the number of the filter chambers 5 is 4 and the ratio of the number of the teeth of the driving gear 93 to the number of the teeth of the transmission gear 91 is 1:2, the stepping motor 92 is set to drive the driving gear 93 to rotate 180 °/half turn each time, and at this time, the transmission gear 91 rotates 90 °/four turns, and exactly one filter chamber 5 is switched.
