Of course, in order to allow a quick installation of the entire filter mechanism, a locking mechanism 10 may also be provided at the end of the second connecting pipe 7.
As shown in fig. 5, a plurality of shunt arcs 301 are uniformly arranged in the shunt tube 3, and the shunt arc 301 is obliquely arranged to divide the shunt tube 3 into a plurality of regions; a plurality of rotary cutting knives 401 are uniformly arranged in the crushing pipe 4 corresponding to the shunting arc piece 301. The plurality of splitter arcs 301 divide the cross-section of the splitter tubes 3 into a plurality of zones and direct the water flow to different zones and directions and toward the crushing tube 4, and move relative to the corresponding shear cutters 401. While the water flow and the rotary cutting knife 401 generate relative motion, the sundries or particles with larger volume in the water body are cut into particles with smaller volume by the rotary cutting knife 401 and continue to flow forwards. The shunting arc piece 301 has also played certain stirring effect to debris or granule in the rivers when shunting for debris or granule can be even get into broken pipe 4 and carry out the breakage.
The shunt arc piece 301 comprises an arc piece body 302, an adjusting shaft 303 and a control motor 304, wherein the adjusting shaft 303 is positioned at the upper end of the arc piece body 302, the adjusting shaft 303 is transversely arranged along the section of the shunt tube 3 and penetrates through the side wall of the shunt tube 3, and the control motor 304 is connected with the tail end of the adjusting shaft 303. When the control motor 304 is operated, the adjustment shaft 303 is driven to rotate, so that the arc piece body 302 rotates, and the angle of the whole shunt arc piece 301 is adjusted. After the angle of reposition of redundant personnel arc piece 301 is adjustable, the rivers direction also corresponding change, and the cutting effect of rotary cutter 401 also can change for the cutting crushing function of whole device is more diversified.
As shown in fig. 9, in order to ensure the sealing between the adjusting shaft 303 and the shunt tube 3, a sealing bearing 304 is installed on the adjusting shaft 303 through the side wall of the shunt tube 3, and the outer edge of the sealing bearing 304 is fixedly connected with the shunt tube 3.
As is well known, the shear cutter 401 cuts the foreign materials or particles by the rotation of the blade. Thus, an external energy source or natural force may be used to rotate the rotary cutter 401, for example, by providing a rotary motor to the rotary cutter and energizing the rotary cutter. In this example, just with the diversion of the diversion arc pieces 301, we can fully utilize the impulsive force of the water flow to drive the rotary cutter 401 to rotate naturally. The blade of the rotary cutter 401 is upward, and can rotate to cut under the action of water flow. In this way, the water flow drives the rotary cutter 401 to rotate, so as to cut the sundries or particles with large volume in the water body, and fully filter and treat the sewage.
The inner wall of the crushing pipe 4 is connected with a movable gear ring 402 along the circumferential direction, the tail part of each rotary cutting knife 401 is coaxially provided with a synchronizing gear 403, and a plurality of synchronizing gears 403 are meshed with the movable gear ring 402. Since the plurality of synchronizing gears 403 are engaged with the movable gear ring 402, the synchronizing gears 403 drive the movable gear ring 402 to move, and simultaneously, the movable gear ring 402 also drives the synchronizing gears 403 to move. When one of the shear cutters 401 and the synchronizing gear 403 rotate, the other shear cutters 401 are also synchronized with the rotational speed of the shear cutter 401. Therefore, even if the water flow in the pipeline is not uniform, or the sizes of the sundries are different, when the crushing pipe 4 is crushed by the rotary cutting knife 401, the better crushing effect can be obtained.
Further, as shown in fig. 10, an adjusting rod 404 is disposed outside the movable gear ring 402, and the adjusting rod 404 penetrates through the wall of the crushing pipe 4 and is hinged with the crushing pipe 4. The adjusting rod 404 is hinged to the crushing pipe 4 and can rotate up and down to drive the movable gear ring 402 to move up and down in the crushing pipe 4. While moving, the movable gear ring 402 is engaged with or disengaged from the synchronizing gear 403, so that the linkage of the rotary cutters 401 is more free and flexible.
Preferably, the number of the diverging arc pieces 301 and the rotary cutter 401 is three in order to sufficiently exert the diverging, agitating and cutting actions of the diverging arc pieces 301 and the rotary cutter 401.
As shown in fig. 11, the flow sensor 8 monitors the flow passing through the storage pipe 6 in real time, and transmits the flow data to the control unit 9, and the control unit 9 sends an operation command to control the operation of the motor 304 according to the flow change in the pipeline, so as to adjust the inclination angle of the shunt arc piece 301. When flow sensor 8 monitors that the flow of accomodating pipe 6 diminishes unusually, give control unit 9 with flow data transfer, control unit 9 sends the operation order and lets control motor 304 operation, it is rotatory to drive adjusting shaft 303, reduce the inclination of reposition of redundant personnel arc piece 301, make rivers get into broken pipe 4 through shunt tubes 3 with higher speed, drive shear knife 401 and cut with higher speed, the debris granule obtains better cutting breakage, thereby increase the flow of accomodating pipe 6, make the flow through whole filter mechanism normal. When the flow sensor 8 detects that the flow of the receiving pipe 6 is increased or abnormal, the control unit 9 will issue an opposite command. In a word, the flow sensor 8 and the control motor 304 operate under the control of the control unit 9 to drive other components to act, so that the whole device can operate normally.
As shown in fig. 6 and 7, a transfer hole 605 is formed in a side surface of the storage tube 6, a movable sealing door 603 is installed on the transfer hole 605, the movable sealing door 603 can move along a circumferential direction of the storage tube 6, a push block 601 is installed on one side of the movable sealing door 603, and a protrusion 602 is arranged on the push block 601; the lower end of the containing pipe 6 is also fixed with a laying net 604, and the second filter tank 5 is arranged on the laying net 604. The holding net 604 serves as a fixing member for the second filtering tank 5.
The second filter tank 5 comprises a circular side wall 501 and a second filter screen 502 connected with the bottom end of the side wall 501, a filter sheet 503 is laid on the second filter screen 502, and a hand-held block 504 is arranged outside the side wall 501. Meanwhile, in order to improve the filtering effect, the filter sheet 503 may be laid in multiple layers.
In order to facilitate the replacement of the second filter 502, the second filter tank 5 is movably connected to the receiving pipe 6. Therefore, a transfer hole 605 is opened in the side surface of the storage tank. In order to smoothly take out the second filtering tank 5, the width of the transfer hole 605 is equal to or more than the half circumference of the receiving pipe 6. For use in sewer pipes, it is necessary to install a movable sealing door 603 in the transfer hole 605. The shape of the movable sealing door 603 matches the shape of the transfer hole 605, and the size is larger than the size of the transfer hole 605. Sliding structures are arranged between the upper end and the lower end of the movable sealing door 603 and the transfer hole 605. The sliding structure may be a fixed sliding groove on the transfer hole 605, and the upper and lower ends of the movable sealing door 603 are inserted into the sliding groove. As shown in fig. 8, a seal 606 is provided between the movable sealing door 603 and the transfer hole 605 for sealing. The sealing strip 606 mainly plays a role in isolation and sealing, and the material of the sealing strip 606 can be selected according to actual needs.
The push block 601 and the protrusion 602 are arranged on the movable sealing door 603, and the hand-held block 504 is arranged on the second filter tank 5, so that the movable sealing door 603 and the second filter tank 5 can be conveniently moved, and the purpose of quickly replacing the second filter screen 502 is achieved.
It is noted that the second filter 502 has a higher precision than the first filter 202 for better filtering.
